Description

本発明は、例えばショーケースの照明配線などに適用される、第１コネクタと、該第１コネクタに差込み連結される第２コネクタからなる配線コネクタに関する。 The present invention relates to a wiring connector including a first connector and a second connector that is plugged and connected to the first connector, which is applied to, for example, lighting wiring of a showcase.

本発明の配線コネクタは、第１コネクタが設置壁に埋設固定されており、第１コネクタに連結された第２コネクタから伸びる出力リードが設置壁の表面に沿う方向に向かって導出されているが、このような配線コネクタは、例えば特許文献１に開示されており公知である。特許文献１の配線コネクタ（防水コネクタ）は、設置壁（内箱）に埋設固定された第１コネクタ（コンセント）と、第１コネクタに接続される第２コネクタ（プラグ）からなり、第１コネクタの正面側から第２コネクタを差込むことにより、コンタクトとプラグピンとを接続することができる。第１コネクタは、該第１コネクタの前縁に設けた固定構造（フランジ）で設置壁に固定されており、該フランジは第２コネクタの周囲において設置壁の表面に露出している。第２コネクタは、傘状に形成された略半部が設置壁の表面から突出しており、この傘状部分の周端面から出力リード（配線コード）が導出されている。傘状の突出部分を手指で摘んで引き抜くことにより、第２コネクタを第１コネクタから分離することができる。 In the wiring connector of the present invention, the first connector is embedded and fixed in the installation wall, and the output lead extending from the second connector connected to the first connector is led out toward the surface of the installation wall. Such a wiring connector is disclosed in, for example, Patent Document 1 and is known. The wiring connector (waterproof connector) of Patent Document 1 is composed of a first connector (outlet) embedded and fixed in an installation wall (inner box) and a second connector (plug) connected to the first connector, and is a first connector. The contact and the plug pin can be connected by inserting the second connector from the front side of the. The first connector is fixed to the installation wall by a fixed structure (flange) provided on the leading edge of the first connector, and the flange is exposed on the surface of the installation wall around the second connector. In the second connector, a substantially half portion formed in an umbrella shape protrudes from the surface of the installation wall, and an output lead (wiring cord) is derived from the peripheral end surface of the umbrella-shaped portion. The second connector can be separated from the first connector by picking and pulling out the umbrella-shaped protruding portion with a finger.

実開昭５７−１７８３８５号公報（第２図）Jikkai Sho 57-178385 (Fig. 2)

特許文献１の配線コネクタにおいては、第２コネクタの設置壁の表面からの突出寸法が大きく設定されているので、第２コネクタの分離操作を容易に行うことができる。しかし、設置壁の表面から大きく突出している分、特許文献１の配線コネクタを例えばショーケースに適用した場合には、陳列室内で第２コネクタが目立ち、ショーケースのデザイン性が低下する。第２コネクタが商品陳列の邪魔になることもある。こうした不都合は、第２コネクタの突出寸法を小さくすれば解消できるが、特許文献１の配線コネクタのように、設置壁の表面から突出した第２コネクタの周端面を手指で摘んで第２コネクタを分離する形態では、少なくとも指先が掛かる程度の突出寸法が必要であり、突出部分の小寸法化には限界があった。 In the wiring connector of Patent Document 1, since the protrusion dimension from the surface of the installation wall of the second connector is set to be large, the separation operation of the second connector can be easily performed. However, when the wiring connector of Patent Document 1 is applied to, for example, a showcase because it protrudes greatly from the surface of the installation wall, the second connector stands out in the display room, and the design of the showcase deteriorates. The second connector may interfere with the product display. Such inconvenience can be solved by reducing the protruding dimension of the second connector, but like the wiring connector of Patent Document 1, the peripheral end surface of the second connector protruding from the surface of the installation wall is picked up by a finger to hold the second connector. In the separated form, at least a protruding dimension that allows the fingertip to hang is required, and there is a limit to reducing the size of the protruding portion.

本発明は、第２コネクタが設置壁の表面において目立たず、しかも邪魔にならない配線コネクタを提供することを目的とする。 An object of the present invention is to provide a wiring connector in which the second connector is inconspicuous on the surface of the installation wall and does not get in the way.

第１コネクタ１１は設置壁７に開口した装着孔２８に背面側から装着されて、装着孔２８の周縁複数個所で係合する固定構造２９で固定されている。設置壁７と正対する側から見て、本体部３６の外郭縁で規定される投影形状が、装着孔２８と設置壁７の表面に露出する固定構造２９とを合成した外郭縁で規定される投影形状よりも大きく形成されており、第１コネクタ１１に第２コネクタ１２が差込み連結された状態において、装着孔２８および第１コネクタ１１の正面の全体が第２コネクタ１２で隠蔽されている。 The first connector 11 is mounted on the mounting hole 28 opened in the installation wall 7 from the back surface side, and is fixed by a fixing structure 29 that engages at a plurality of peripheral edges of the mounting hole 28. When viewed from the side facing the installation wall 7, the projected shape defined by the outer edge of the main body 36 is defined by the outer edge obtained by combining the mounting hole 28 and the fixed structure 29 exposed on the surface of the installation wall 7. It is formed larger than the projected shape, and in a state where the second connector 12 is inserted and connected to the first connector 11, the entire front surface of the mounting hole 28 and the first connector 11 is concealed by the second connector 12.

固定構造２９は、装着孔２８の周縁壁の正面と複数個所で係合する係止爪３０と、装着孔２８の周縁壁の背面を受止めるフランジ部３１を備えている。第１コネクタ１１に第２コネクタ１２が差込み連結された状態において、係止爪３０が本体部３６の背面に設けた収容凹部５４に収容されて、本体部３６の背面の四周縁部が設置壁７に密着されている。 The fixed structure 29 includes locking claws 30 that engage with the front surface of the peripheral wall of the mounting hole 28 at a plurality of locations, and a flange portion 31 that receives the back surface of the peripheral wall of the mounting hole 28. In a state where the second connector 12 is inserted and connected to the first connector 11, the locking claw 30 is accommodated in the accommodating recess 54 provided on the back surface of the main body 36, and the four peripheral edges on the back surface of the main body 36 are the installation walls. It is in close contact with 7.

ハウジング１５と本体部３６の間に、第１コネクタ１１に差込み連結された第２コネクタ１２の連結状態を保持する保持構造５７が設けられている。保持構造５７は、第１コネクタ１１側に設けられる第１係合体５８と、第２コネクタ１２側に設けられる第２係合体５９とで構成されて、第２係合体５９が第１係合体５８に対して弾性変形されて係脱されるようになっている。第２係合体５９を係合解除状態に弾性変形させる解除操作部６０が、差込凹部４３の壁面に配置されている形態を採ることができる。 A holding structure 57 is provided between the housing 15 and the main body 36 to hold the connected state of the second connector 12 which is inserted and connected to the first connector 11. The holding structure 57 is composed of a first engaging body 58 provided on the first connector 11 side and a second engaging body 59 provided on the second connector 12 side, and the second engaging body 59 is the first engaging body 58. It is elastically deformed and disengaged. The release operation unit 60 that elastically deforms the second engaging body 59 into the disengaged state can be arranged on the wall surface of the insertion recess 43.

第１係合体５８は、ハウジング１５に一体に形成された係合爪６１で構成されている。第２係合体５９は、本体部３６と一体に形成された片持ち状の弾性アーム６２と、弾性アーム６２の揺動先端に突設されて、係合爪６１と係脱される係合突起６３を備えている。第２係合体５９の弾性アーム６２が、差込凹部４３を囲む壁面に切欠き形成されたアームスリット６４に臨んで配置されて、弾性アーム６２が解除操作部６０を兼ねている形態を採ることができる。 The first engaging body 58 is composed of an engaging claw 61 integrally formed with the housing 15. The second engaging body 59 is a cantilever elastic arm 62 formed integrally with the main body 36, and an engaging protrusion that is projected from the swinging tip of the elastic arm 62 and is engaged with and disengaged from the engaging claw 61. It has 63. The elastic arm 62 of the second engaging body 59 is arranged so as to face the arm slit 64 formed in the wall surface surrounding the insertion recess 43, and the elastic arm 62 also serves as the release operation portion 60. Can be done.

本体部３６の背面中央を間にして一対の差込凹部４３が設けられている。弾性アーム６２が、各差込凹部４３を囲む壁面の本体部３６の背面中央側に形成したアームスリット６４に臨むように配置されていることが好ましい。 A pair of insertion recesses 43 are provided with the center of the back surface of the main body 36 in between. It is preferable that the elastic arm 62 is arranged so as to face the arm slit 64 formed on the back center side of the main body portion 36 of the wall surface surrounding each insertion recess 43.

ハウジング１５の底壁１６の内面から正面開口１８側に向かってソケット部２０が突設され、本体部３６の裏面から背面側に向かってソケット部２０に外嵌または内嵌するプラグ部３９が突設されている。雄コンタクト３８と雌コンタクト１９のいずれか一方がソケット部２０に設けられ、他方がプラグ部３９に設けられている。第２コネクタ１２の上下周面のいずれか一方に、給電リード９用の導出孔５３が形成されている。第２コネクタ１２が第１コネクタ１１に対して、導出孔５３が第２コネクタ１２の上周面で開口する標準姿勢と、導出孔５３が第２コネクタ１２の下周面で開口する反転姿勢とに差込み連結可能に構成されている形態を採ることができる。 The socket portion 20 projects from the inner surface of the bottom wall 16 of the housing 15 toward the front opening 18 side, and the plug portion 39 that is externally or internally fitted into the socket portion 20 projects from the back surface side of the main body portion 36 toward the back surface side. It is installed. One of the male contact 38 and the female contact 19 is provided in the socket portion 20, and the other is provided in the plug portion 39. A lead-out hole 53 for the power feeding lead 9 is formed on one of the upper and lower peripheral surfaces of the second connector 12. A standard posture in which the second connector 12 opens with respect to the first connector 11 with the lead-out hole 53 on the upper peripheral surface of the second connector 12, and an inverted posture in which the lead-out hole 53 opens on the lower peripheral surface of the second connector 12. It is possible to take a form in which it can be plugged into and connected.

本発明の配線コネクタにおいては、指先を差込むための一対の差込凹部４３を本体部３６に凹み形成して、該差込凹部４３を囲む壁面を背面側に膨出形成した。第１コネクタ１１に第２コネクタ１２が差込み連結された状態において、本体部３６の背面側に膨出した差込凹部４３を囲む壁面を、正面開口１８からハウジング１５に差し込まれてハウジング１５の内部に収容した。こうした配線コネクタによれば、第２コネクタ１２を分離するときには、一対の差込凹部４３に差し込んだ指先で本体部３６を摘まんで、第１コネクタ１１から第２コネクタ１２を分離できるので、本体部３６を指先が掛かる程の厚み寸法にする必要がなく、本体部３６を薄型化できる。また、凹み形成された一対の差込凹部４３は本体部３６の表面よりも背面側に位置するので、本体部３６の表面に分離操作のための突起等が形成されることもなく、この点でも本体部３６を薄型化できる。従って、本体部３６の表面を平坦面とし、さらに本体部３６の厚み寸法を、その周端面３７から出力リード９が導出できる程度まで薄くすることができる。以上のように、本発明によれば、設置壁７から突出する第２コネクタ１２の薄型化を実現して、設置壁７の表面において目立たず、しかも邪魔にならない配線コネクタを得ることができる。 In the wiring connector of the present invention, a pair of insertion recesses 43 for inserting fingertips are formed as recesses in the main body 36, and a wall surface surrounding the insertion recesses 43 is formed to bulge toward the back surface side. In a state where the second connector 12 is inserted and connected to the first connector 11, the wall surface surrounding the insertion recess 43 bulging toward the back side of the main body 36 is inserted into the housing 15 from the front opening 18 and inside the housing 15. Contained in. According to such a wiring connector, when separating the second connector 12, the main body 36 can be pinched with the fingertips inserted into the pair of insertion recesses 43, and the second connector 12 can be separated from the first connector 11. It is not necessary to make the thickness of 36 so that the fingertips can be hung on it, and the main body 36 can be made thinner. Further, since the pair of recessed recesses 43 are located on the back side of the surface of the main body 36, no protrusions or the like for separation operation are formed on the surface of the main body 36, which is a point. However, the main body 36 can be made thinner. Therefore, the surface of the main body 36 can be made flat, and the thickness of the main body 36 can be reduced to such an extent that the output lead 9 can be derived from the peripheral end surface 37 thereof. As described above, according to the present invention, it is possible to realize a thinning of the second connector 12 protruding from the installation wall 7, and to obtain a wiring connector that is inconspicuous on the surface of the installation wall 7 and does not get in the way.

設置壁７と正対する側から見て、本体部３６の外郭縁で規定される投影形状を、設置壁７に開設した装着孔２８と設置壁７の表面に露出する第１コネクタ１１の固定構造２９とを合成した外郭縁で規定される投影形状よりも大きく形成して、第１コネクタ１１に第２コネクタ１２が差込み連結された状態において、装着孔２８および第１コネクタ１１の正面の全体を第２コネクタ１２で隠蔽した。これによれば、第２コネクタ１２で装着孔２８および第１コネクタ１１を覆い隠して、設置壁７と正対する側から見たときの配線コネクタまわりの見栄えを向上できる。また、第１コネクタ１１は第２コネクタ１２で隠蔽されるので、第２コネクタ１２の色のみを設置壁７の塗装色に合わせることで、設置壁７上において配線コネクタを目立たなくすることができる。これにより、例えば設置壁７の塗装色が複数ラインナップされるショーケース等においては、第１コネクタ１１の色を複数用意する必要がない分、配線コネクタの製造および保管に要するコストを低減できる。なお、従来の配線コネクタにおいては、第１コネクタの固定構造が設置壁の外面に露出しているため、第２コネクタに加え第１コネクタも設置壁の塗装色に合わせる必要がある分、配線コネクタの製造および保管に要するコストが上昇するのを避けられない。 A fixed structure of a mounting hole 28 formed in the installation wall 7 and a first connector 11 that exposes the projected shape defined by the outer edge of the main body 36 to the surface of the installation wall 7 when viewed from the side facing the installation wall 7. The entire front surface of the mounting hole 28 and the first connector 11 is formed in a state where the second connector 12 is inserted and connected to the first connector 11 by forming a shape larger than the projected shape defined by the outer edge obtained by combining 29 and 29. It was concealed by the second connector 12. According to this, the mounting hole 28 and the first connector 11 can be covered with the second connector 12, and the appearance around the wiring connector when viewed from the side facing the installation wall 7 can be improved. Further, since the first connector 11 is concealed by the second connector 12, the wiring connector can be made inconspicuous on the installation wall 7 by matching only the color of the second connector 12 with the paint color of the installation wall 7. .. As a result, for example, in a showcase or the like in which a plurality of paint colors of the installation wall 7 are lined up, it is not necessary to prepare a plurality of colors of the first connector 11, so that the cost required for manufacturing and storing the wiring connector can be reduced. In the conventional wiring connector, since the fixed structure of the first connector is exposed on the outer surface of the installation wall, it is necessary to match the first connector in addition to the second connector with the paint color of the installation wall. It is inevitable that the cost of manufacturing and storing the product will increase.

第１コネクタ１１に第２コネクタ１２が差込み連結された状態において、本体部３６の背面に設けた収容凹部５４に、装着孔２８の周縁壁の正面と複数個所で係合する係止爪３０を収容して、本体部３６の背面の四周縁部が設置壁７に密着するようにした。これによれば、設置壁７の表面から突出した係止爪３０を、本体部３６の厚み寸法内に収めて、設置壁７から突出する本体部３６をより薄型化できる。また、本体部３６と設置壁７との間の隙間を無くし、配線コネクタを本体部３６の周端面側から見たときの印象をすっきりとしたものにすることができる。また、隙間がない分、本体部３６の外周縁に溜まった埃等の清掃を容易に行える。 In a state where the second connector 12 is inserted and connected to the first connector 11, locking claws 30 that engage with the front surface of the peripheral wall of the mounting hole 28 at a plurality of places are provided in the accommodating recess 54 provided on the back surface of the main body 36. It was housed so that the four peripheral edges on the back surface of the main body 36 were in close contact with the installation wall 7. According to this, the locking claw 30 protruding from the surface of the installation wall 7 can be accommodated within the thickness dimension of the main body 36, and the main body 36 protruding from the installation wall 7 can be made thinner. Further, the gap between the main body 36 and the installation wall 7 can be eliminated, and the impression of the wiring connector when viewed from the peripheral end surface side of the main body 36 can be made clear. Further, since there is no gap, dust and the like accumulated on the outer peripheral edge of the main body 36 can be easily cleaned.

第１コネクタ１１側に設けられる第１係合体５８と、第２コネクタ１２側に設けられる第２係合体５９とで構成される保持構造５７は、第２係合体５９を第１係合体５８に対して弾性変形して係脱するようになっている。第２係合体５９を係合解除状態に弾性変形させる解除操作部６０を差込凹部４３の壁面に配置する。このように、差込凹部４３の壁面に配置した解除操作部６０によれば、第１コネクタ１１に差込み連結された第２コネクタ１２の連結状態を保持する保持構造５７を配線コネクタに設けた場合でも、本体部３６の突出寸法が大きくなることがなく、適正な連結状態を維持しながらも、目立たず、しかも邪魔にならない配線コネクタを得ることができる。 The holding structure 57 composed of the first engaging body 58 provided on the first connector 11 side and the second engaging body 59 provided on the second connector 12 side makes the second engaging body 59 into the first engaging body 58. On the other hand, it is elastically deformed and disengaged. The disengaging operation unit 60 that elastically deforms the second engaging body 59 into the disengaged state is arranged on the wall surface of the insertion recess 43. As described above, according to the release operation unit 60 arranged on the wall surface of the insertion recess 43, when the wiring connector is provided with the holding structure 57 that holds the connected state of the second connector 12 that is inserted and connected to the first connector 11. However, the protruding dimension of the main body 36 does not become large, and it is possible to obtain a wiring connector that is inconspicuous and does not get in the way while maintaining an appropriate connection state.

第２係合体５９の弾性アーム６２を、差込凹部４３の壁面に切欠き形成されたアームスリット６４に臨んで配置して、弾性アーム６２が解除操作部６０を兼ねるようにした。これによれば、保持構造５７の係合を解除する解除操作部６０を別途設ける必要がなく、簡素な構造で解除操作部６０を差込凹部４３の内面に配置することができる。また、アームスリット６４を形成したことによって差込凹部４３の壁面に生じた切欠き部は弾性アーム６２で塞がれるので、アームスリット６４を形成したことによる第２コネクタ１２の外観の変化を最小化でき、配線コネクタが目立つようなこともない。 The elastic arm 62 of the second engaging body 59 is arranged so as to face the arm slit 64 formed in the wall surface of the insertion recess 43 so that the elastic arm 62 also serves as the release operation portion 60. According to this, it is not necessary to separately provide the release operation unit 60 for disengaging the holding structure 57, and the release operation unit 60 can be arranged on the inner surface of the insertion recess 43 with a simple structure. Further, since the notch formed on the wall surface of the insertion recess 43 due to the formation of the arm slit 64 is closed by the elastic arm 62, the change in the appearance of the second connector 12 due to the formation of the arm slit 64 is minimized. The wiring connector does not stand out.

本体部３６の背面中央を間にして一対の差込凹部４３を設け、各差込凹部４３を囲む壁面の本体部３６の背面中央側に形成したアームスリット６４に臨むように弾性アーム６２を配置した。これによれば、一対の差込凹部４３に指先を差込み、本体部３６を摘まむ動作を行うだけで、意識することなく解除操作部６０で保持構造５７の係合を解除できるので、第１コネクタ１１から第２コネクタ１２を分離する動作を簡便化できる。 A pair of insertion recesses 43 are provided with the center of the back surface of the main body portion 36 in between, and the elastic arm 62 is arranged so as to face the arm slit 64 formed on the back center side of the main body portion 36 of the wall surface surrounding each insertion recess 43. bottom. According to this, the engagement of the holding structure 57 can be disengaged by the disengaging operation unit 60 without being aware of it, simply by inserting the fingertips into the pair of insertion recesses 43 and performing the operation of pinching the main body portion 36. The operation of separating the second connector 12 from the connector 11 can be simplified.

第２コネクタ１２を第１コネクタ１１に対して、導出孔５３が第２コネクタ１２の上周面で開口する標準姿勢と、導出孔５３が第２コネクタ１２の下周面で開口する反転姿勢に差込み連結可能に構成した。これによれば、第２コネクタ１２を差込み連結する姿勢を変更することで、出力リード９を上向きに導出する状態と、下向きに導出する状態とに切り換えることができ、出力リード９の配線形態の自由度を向上して、出力リード９が煩雑に配線されるのを抑制できる。また、煩雑に配線されるのを抑制することで、出力リード９に陳列商品が引っ掛かることがなく、出力リード９の断線のリスクを低減できる。 The second connector 12 has a standard posture in which the lead-out hole 53 opens on the upper peripheral surface of the second connector 12 with respect to the first connector 11, and the lead-out hole 53 has an inverted posture in which the lead-out hole 53 opens on the lower peripheral surface of the second connector 12. It is configured so that it can be plugged in and connected. According to this, by changing the posture in which the second connector 12 is inserted and connected, it is possible to switch between a state in which the output lead 9 is led out upward and a state in which the output lead 9 is led out downward. The degree of freedom can be improved to prevent the output leads 9 from being complicatedly wired. Further, by suppressing complicated wiring, the display product is not caught on the output lead 9, and the risk of disconnection of the output lead 9 can be reduced.

It is composed of a flange portion 31 provided in a circumferential shape on the outer surface of the peripheral wall 17 on the rear side from the front surface of the above. As shown in FIG. 8, two locking claws 30 are provided on the upper and lower peripheral walls 17. The left and right locking claws 30 are provided in a line symmetry with the left and right center of the housing 15 as a symmetrical line in the front view, and the forming interval thereof is that of the locking claw 30 above the lower locking claw 30. Is bigger. The clearance dimension between the rear surface of the locking claw 30 and the front surface of the flange portion 31 is substantially the same as the thickness dimension of the back plate 7 (see FIG. 4). The flange portion 31 is formed in an intermittent shape by cutting out the flange portion 31 of the portion facing the locking claw 30, but this is due to the convenience of the mold at the time of molding, and the flange portion 31 is continuous. It may be formed in.

装着孔２８の上下の縁部には、それぞれ２個の台形状の切欠き部３２が設けられている。切欠き部３２は、第１コネクタ１１を背面板７に固定する際に、先の係止爪３０を背面板７の前面（正面）側に係止させるために設けられている。切欠き部３２は、その形成間隔が係止爪３０と同一間隔に設定されており、正面視において装着孔２８の中央から左に偏った位置に形成されている。 Two trapezoidal notches 32 are provided at the upper and lower edges of the mounting hole 28, respectively. The notch portion 32 is provided to lock the first locking claw 30 to the front surface (front surface) side of the back plate 7 when the first connector 11 is fixed to the back plate 7. The notch portion 32 is formed at the same interval as the locking claw 30, and is formed at a position biased to the left from the center of the mounting hole 28 in front view.

第１コネクタ１１は背面板７に対して裏面側から組付けられる。具体的には、まず、背面板７の裏面側において各係止爪３０を、それぞれ切欠き部３２と位置合わせしたうえで、第１コネクタ１１を図３において前側に押込んで、切欠き部３２に係止爪３０を差込む。次いで第１コネクタ１１を図３において右側にスライドさせることにより、装着孔２８の周縁壁の後面（背面）がフランジ部３１で受止められた状態で背面板７の前面に各係止爪３０が係合され固定が完了する。背面板７の表面に係止爪３０を係止させた状態においては、フランジ部３１よりも前側の周囲壁１７は、装着孔２８に嵌まり込んでおり、第１コネクタ１１の上下左右方向の移動が規制されている（図１および図４参照）。さらに、装着孔２８の周縁部分の背面板７が、係止爪３０とフランジ部３１で挟み込まれており、第１コネクタ１１の前後方向の移動が規制されている（図１参照）。従って、第１コネクタ１１は、固定構造２９で背面板７に対してがたつくことなく固定される。 The first connector 11 is assembled to the back plate 7 from the back surface side. Specifically, first, after aligning each of the locking claws 30 with the notch portion 32 on the back surface side of the back plate 7, the first connector 11 is pushed to the front side in FIG. 3, and the notch portion 32 Insert the locking claw 30 into the. Next, by sliding the first connector 11 to the right in FIG. 3, each locking claw 30 is placed on the front surface of the back plate 7 in a state where the rear surface (back surface) of the peripheral wall of the mounting hole 28 is received by the flange portion 31. Engage and fix is complete. In a state where the locking claw 30 is locked to the surface of the back plate 7, the peripheral wall 17 on the front side of the flange portion 31 is fitted into the mounting hole 28, and is in the vertical and horizontal directions of the first connector 11. Movement is restricted (see Figures 1 and 4). Further, the back plate 7 at the peripheral edge of the mounting hole 28 is sandwiched between the locking claw 30 and the flange portion 31, and the movement of the first connector 11 in the front-rear direction is restricted (see FIG. 1). Therefore, the first connector 11 is fixed to the back plate 7 without rattling by the fixing structure 29.

図３において、符号３３は、第１コネクタ１１が背面板７に固定されたとき、背面板７の表面よりも前方に突出するように形成された抜け止め突起である。この抜け止め突起が背面板７の裏面側に抜け出ない限り、第１コネクタ１１を分離方向にスライドさせることができず、従って第１コネクタ１１が背面板７から分離されるのをよく防止できる。第１コネクタ１１が背面板７に固定された状態では、周囲壁１７の前端面と背面板７の表面とは略面一状になっており、背面板７の表面より前側には、４個の係止爪３０と、抜け止め突起３３の先端側の一部が突出している。 In FIG. 3, reference numeral 33 is a retaining protrusion formed so as to project forward from the surface of the back plate 7 when the first connector 11 is fixed to the back plate 7. Unless the retaining protrusion comes out to the back surface side of the back plate 7, the first connector 11 cannot be slid in the separation direction, and therefore the first connector 11 can be well prevented from being separated from the back plate 7. When the first connector 11 is fixed to the back plate 7, the front end surface of the peripheral wall 17 and the surface of the back plate 7 are substantially flush with each other, and four are on the front side of the surface of the back plate 7. The locking claw 30 and a part of the retaining protrusion 33 on the tip end side are projected.

As shown in FIGS. 4 and 5, the main body 36 is formed in a rectangular flat plate shape having a flat surface and long left and right, and power is supplied from the peripheral end surface 37 of the main body 36 toward the surface of the back plate 7. Lead 9 has been derived. In this embodiment, the vertical dimension of the main body 36 is 36 mm, the horizontal dimension is 75 mm, the front-rear dimension (thickness dimension) is 5 mm, and the front four corners and the front ridge line are rounded. Since the front-rear dimension of the main body 36 may be set larger than the diameter of the power supply lead 9, for example, when the power supply lead 9 having a diameter of 3 mm is used, the front-rear dimension of the main body 36 is made thinner. be able to.

図１および図７に示すように本体部３６の後面の中央には、雄コンタクト３８が設けられるプラグ部３９が後（背面）向きに突設されている。プラグ部３９は、ブロック状の基端ブロック４０と、筒状の外嵌筒４１とで構成されており、両コネクタ１１・１２を連結した状態において、外嵌筒４１はソケット部２０に外嵌する。プラグ部３９は、背面視において四隅が丸められた横長直方体状に形成されている（図８参照）。基端ブロック４０には３個の雄コンタクト３８が左右方向に等間隔で設けられており、左右中央の雄コンタクト３８は、本体部３６の中心を通る前後方向に伸びる軸線に沿って設けられる。各雄コンタクト３８は、先端が基端ブロック４０から後向きに突出する状態で基端ブロック４０に設けたコンタクト孔４２に配置される。 As shown in FIGS. 1 and 7, a plug portion 39 provided with a male contact 38 is provided so as to project rearward (backward) in the center of the rear surface of the main body portion 36. The plug portion 39 is composed of a block-shaped base end block 40 and a tubular outer fitting cylinder 41, and the outer fitting cylinder 41 is outerly fitted to the socket portion 20 in a state where both connectors 11 and 12 are connected. do. The plug portion 39 is formed in a horizontally long rectangular parallelepiped shape with four corners rounded in the rear view (see FIG. 8). The base end block 40 is provided with three male contacts 38 at equal intervals in the left-right direction, and the male contacts 38 at the center of the left and right are provided along an axis extending in the front-rear direction passing through the center of the main body portion 36. Each male contact 38 is arranged in a contact hole 42 provided in the proximal block 40 with its tip protruding rearward from the proximal block 40.

本体部３６には、指先を差込むための一対の差込凹部４３が凹み形成されており、該差込凹部４３を囲む壁面が背面側に膨出形成されている。一対の差込凹部４３は、プラグ部３９（本体部３６の背面中央）を間にして設けられている。本実施例の第２コネクタ１２は、後側のコネクタベース４６と、前側のカバー体４７とを溶着固定して形成される。コネクタベース４６はベース部４８と、ベース部４８に一体的に形成される椀状の左右一対のカップ部４９を備えており、ベース部４８の後面にプラグ部３９が設けられている。カバー体４７は、カバー主壁５０と、カバー主壁５０の四周縁部から後向きに立設されるカバー周壁５１とで後面に開口する凹部を備えた角皿状に形成されている。カバー主壁５０には、コネクタベース４６の一対のカップ部４９に対応する位置に貫通孔５２が開設されている。カップ部４９と貫通孔５２とで差込凹部４３が形成されており、カップ部４９は差込凹部４３を囲む壁面を構成している。 A pair of insertion recesses 43 for inserting fingertips are formed in the main body 36, and a wall surface surrounding the insertion recesses 43 is formed to bulge on the back surface side. The pair of insertion recesses 43 are provided with the plug portion 39 (center of the back surface of the main body portion 36) in between. The second connector 12 of this embodiment is formed by welding and fixing the connector base 46 on the rear side and the cover body 47 on the front side. The connector base 46 includes a base portion 48 and a pair of bowl-shaped left and right cup portions 49 integrally formed with the base portion 48, and a plug portion 39 is provided on the rear surface of the base portion 48. The cover body 47 is formed in a square dish shape having a recess that opens to the rear surface of the cover main wall 50 and the cover peripheral wall 51 that is erected rearward from the four peripheral edges of the cover main wall 50. A through hole 52 is provided in the cover main wall 50 at a position corresponding to the pair of cup portions 49 of the connector base 46. The insertion recess 43 is formed by the cup portion 49 and the through hole 52, and the cup portion 49 constitutes a wall surface surrounding the insertion recess 43.

図８に示すように、本体部３６を正面（背面板７と正対する側）から見て、二点鎖線で示す本体部３６（カバー主壁５０）の外郭縁で規定される投影形状は、装着孔２８と背面板７の表面に露出する固定構造２９とを合成した外郭縁で規定される投影形状よりも大きく形成されて、両コネクタ１１・１２が差込み連結された状態において、第２コネクタ１２で装着孔２８および第１コネクタ１１の正面の全体を隠蔽している。これによれば、第２コネクタ１２で装着孔２８および第１コネクタ１１を覆い隠して、背面板７と正対する側から見たときの配線コネクタまわりの見栄えを向上できる。また、第１コネクタ１１は第２コネクタ１２で隠蔽されるので、第２コネクタ１２の色のみを背面板７の塗装色に合わせることで、背面板７上において配線コネクタを目立たなくすることができる。これにより、例えば背面板７の塗装色が複数ラインナップされるショーケース等においては、第１コネクタ１１の色を複数用意する必要がない分、配線コネクタの製造および保管に要するコストを低減できる。なお、従来の配線コネクタにおいては、第１コネクタの固定構造が設置壁の外面に露出しているため、第２コネクタに加え第１コネクタも設置壁の塗装色に合わせる必要がある分、配線コネクタの製造および保管に要するコストが上昇するのを避けられない。 As shown in FIG. 8, when the main body 36 is viewed from the front (the side facing the back plate 7), the projected shape defined by the outer edge of the main body 36 (cover main wall 50) indicated by the alternate long and short dash line is The second connector is formed in a state where the mounting hole 28 and the fixed structure 29 exposed on the surface of the back plate 7 are formed larger than the projected shape defined by the outer edge, and both the connectors 11 and 12 are inserted and connected. 12 hides the entire front surface of the mounting hole 28 and the first connector 11. According to this, the mounting hole 28 and the first connector 11 can be covered with the second connector 12, and the appearance around the wiring connector when viewed from the side facing the back plate 7 can be improved. Further, since the first connector 11 is concealed by the second connector 12, the wiring connector can be made inconspicuous on the back plate 7 by matching only the color of the second connector 12 with the paint color of the back plate 7. .. As a result, for example, in a showcase or the like in which a plurality of paint colors of the back plate 7 are lined up, it is not necessary to prepare a plurality of colors of the first connector 11, so that the cost required for manufacturing and storing the wiring connector can be reduced. In the conventional wiring connector, since the fixed structure of the first connector is exposed on the outer surface of the installation wall, it is necessary to match the first connector in addition to the second connector with the paint color of the installation wall. It is inevitable that the cost of manufacturing and storing the product will increase.

コネクタベース４６およびカバー体４７は射出成型品からなり、本実施例ではそれぞれＡＢＳ樹脂を素材として形成した。なお、ＡＢＳ樹脂以外の合成樹脂素材でコネクタベース４６およびカバー体４７を形成してもよい。コネクタベース４６とカバー体４７とは、収容凹部５４にベース部４８と一対のカップ部４９の開口縁部が収容される状態で溶着固定される。両者４６・４７を溶着固定した状態におけるカバー体４７部分が、両コネクタ１１・１２を連結した状態において、背面板７の表面よりも外面側に位置する本体部３６となる。給電リード９は、コネクタベース４６とカバー体４７とを接合したときに形成される、周端面３７の上周面で開口する３個の導出孔５３から導出されており、各導出孔５３は周端面３７と雄コンタクト３８が装着されるコンタクト孔４２とを連通している。 The connector base 46 and the cover body 47 are made of injection-molded products, and in this embodiment, they are each made of ABS resin as a material. The connector base 46 and the cover body 47 may be formed of a synthetic resin material other than ABS resin. The connector base 46 and the cover body 47 are welded and fixed in a state where the base portion 48 and the opening edges of the pair of cup portions 49 are accommodated in the accommodating recess 54. The cover body 47 portion in the state where both 46 and 47 are welded and fixed becomes the main body portion 36 located on the outer surface side of the surface of the back plate 7 in the state where both connectors 11 and 12 are connected. The power supply lead 9 is led out from three lead-out holes 53 opened on the upper peripheral surface of the peripheral end surface 37, which are formed when the connector base 46 and the cover body 47 are joined, and each lead-out hole 53 is peripheral. The end face 37 and the contact hole 42 to which the male contact 38 is mounted are communicated with each other.

第１コネクタ１１に第２コネクタ１２が差込み連結された状態においては、平板状の本体部３６の後面側に膨出したカップ部４９（差込凹部４３を囲む壁面）は、正面開口１８からハウジング１５の内部に差し込まれてハウジング１５の内部に収容されている。これにより、第２コネクタ１２の本体部３６のみが、背面板７の表面より前側に突出している。また、各雌コンタクト１９と雄コンタクト３８とは接続されており、プラグ部３９の外嵌筒４１はソケット部２０に外嵌して、両者２０・４１の間の周回状の隙間が防水パッキン２６で封止され、両コンタクト１９・３８の接続部分を防水している。これにより、ハウジング１５内に水が浸入した場合でも、雌コンタクト１９および雄コンタクト３８に水が付着することがない。 In a state where the second connector 12 is inserted and connected to the first connector 11, the cup portion 49 (the wall surface surrounding the insertion recess 43) that bulges toward the rear surface side of the flat plate-shaped main body portion 36 is housing from the front opening 18. It is inserted inside the 15 and housed inside the housing 15. As a result, only the main body 36 of the second connector 12 protrudes forward from the surface of the back plate 7. Further, each female contact 19 and the male contact 38 are connected, the outer fitting cylinder 41 of the plug portion 39 is outer-fitted to the socket portion 20, and the circumferential gap between the two 20 and 41 is the waterproof packing 26. It is sealed with and waterproofs the connection parts of both contacts 19 and 38. As a result, even if water enters the housing 15, the water does not adhere to the female contact 19 and the male contact 38.

上記のように、本実施例に係る配線コネクタにおいては、指先を差込むための一対の差込凹部４３を本体部３６に凹み形成して、該差込凹部４３を囲む壁面（カップ部４９）を後面側に膨出形成した。第１コネクタ１１に第２コネクタ１２が差込み連結された状態において、本体部３６の後面側に膨出した差込凹部４３を囲む壁面を、正面開口１８からハウジング１５に差し込まれてハウジング１５の内部に収容した。こうした配線コネクタによれば、第２コネクタ１２を分離するときには、一対の差込凹部４３に差し込んだ指先で本体部３６を摘まんで、第１コネクタ１１から第２コネクタ１２を分離できるので、本体部３６を指先が掛かる程の厚み寸法にする必要がない。また、凹み形成された一対の差込凹部４３は本体部３６の表面よりも背面側に位置するので、本体部３６の表面に分離操作のための突起等が形成されることもない。従って、本体部３６の表面を平坦面とし、さらに本体部３６の厚み寸法を、その周端面３７から給電リード９が導出できる程度まで薄くすることができる。以上のように、本実施例によれば、背面板７から突出する第２コネクタ１２の薄型化を実現して、背面板７の表面において目立たず、しかも邪魔にならない配線コネクタを得ることができる。 As described above, in the wiring connector according to the present embodiment, a pair of insertion recesses 43 for inserting fingertips are formed in the main body portion 36, and a wall surface (cup portion 49) surrounding the insertion recess 43 is formed. Was formed to bulge on the posterior surface side. In a state where the second connector 12 is inserted and connected to the first connector 11, the wall surface surrounding the insertion recess 43 bulging toward the rear surface side of the main body 36 is inserted into the housing 15 from the front opening 18 and inside the housing 15. Contained in. According to such a wiring connector, when separating the second connector 12, the main body 36 can be pinched with the fingertips inserted into the pair of insertion recesses 43, and the second connector 12 can be separated from the first connector 11. It is not necessary to make 36 thick enough to hang a fingertip. Further, since the pair of recessed recesses 43 are located on the back surface side of the surface of the main body 36, protrusions or the like for the separation operation are not formed on the surface of the main body 36. Therefore, the surface of the main body 36 can be made flat, and the thickness of the main body 36 can be reduced to such an extent that the power feeding lead 9 can be derived from the peripheral end surface 37 thereof. As described above, according to the present embodiment, it is possible to realize a thinning of the second connector 12 protruding from the back plate 7, and to obtain a wiring connector that is inconspicuous on the surface of the back plate 7 and does not get in the way. ..

コネクタベース４６とカバー体４７とを一体化したのちは、ベース部４８および一対のカップ部４９部分を除くカバー体４７の凹部部分に、背面視においてコ字状に形成される左右一対の収容凹部５４が形成される。両コネクタ１１・１２が差込み連結された状態においては、当該収容凹部５４に、背面板７の表面から突出した係止爪３０（固定構造２９の一部）と抜け止め突起３３の先端が収容されて、カバー体４７のカバー周壁５１の後端面（本体部３６の背面の四周縁部）が背面板７に密着している。これによれば、背面板７の表面から突出した係止爪３０と抜け止め突起３３を、本体部３６の厚み寸法内に収めて、背面板７から突出する本体部３６を薄型化できる。また、本体部３６と背面板７との間の隙間を無くし、配線コネクタを本体部３６の周端面側から見たときの印象をすっきりとしたものにすることができる。また、隙間がない分、本体部３６の外周縁に溜まった埃等の清掃を容易に行える。 After integrating the connector base 46 and the cover body 47, a pair of left and right accommodating recesses formed in a U shape in the rear view in the recessed portion of the cover body 47 excluding the base portion 48 and the pair of cup portions 49. 54 is formed. In the state where both connectors 11 and 12 are inserted and connected, the locking claw 30 (a part of the fixed structure 29) protruding from the surface of the back plate 7 and the tip of the retaining protrusion 33 are accommodated in the accommodating recess 54. The rear end surfaces of the cover peripheral wall 51 of the cover body 47 (four peripheral edges on the back surface of the main body portion 36) are in close contact with the back plate 7. According to this, the locking claw 30 and the retaining protrusion 33 protruding from the surface of the back plate 7 can be accommodated within the thickness dimension of the main body 36, and the main body 36 protruding from the back plate 7 can be made thinner. Further, the gap between the main body 36 and the back plate 7 can be eliminated, and the impression of the wiring connector when viewed from the peripheral end surface side of the main body 36 can be made clear. Further, since there is no gap, dust and the like accumulated on the outer peripheral edge of the main body 36 can be easily cleaned.

ハウジング１５と本体部３６の間に、第１コネクタ１１に差込み連結された第２コネクタ１２の連結状態を保持する左右一対の保持構造５７が設けられている。各保持構造５７は、第１コネクタ１１側に設けられる第１係合体５８と、第２コネクタ１２側に設けられる第２係合体５９とで構成されており、第２係合体５９が、第１係合体５８に対して弾性変形されて係脱されるようになっている。第２係合体５９を係合解除状態に弾性変形させる解除操作部６０は、差込凹部４３の内面に配置されている。 A pair of left and right holding structures 57 are provided between the housing 15 and the main body 36 to hold the connected state of the second connector 12 that is inserted and connected to the first connector 11. Each holding structure 57 is composed of a first engaging body 58 provided on the first connector 11 side and a second engaging body 59 provided on the second connector 12 side, and the second engaging body 59 is the first. It is elastically deformed with respect to the engaging body 58 so that it can be engaged and disengaged. The disengaging operation unit 60 that elastically deforms the second engaging body 59 into the disengaged state is arranged on the inner surface of the insertion recess 43.

第１係合体５８は、ハウジング１５に一体に形成された一対の係合爪６１で構成されている。係合爪６１はＬ字状に形成されており、底壁１６から前向きに突出している。一対の係合爪６１のＬ字状の先端部分は、互いに向かい合っている。第２係合体５９は、カバー主壁５０（本体部３６）と一体に形成された片持ち状の弾性アーム６２と、弾性アーム６２の揺動先端に突設されて、係合爪６１が係脱される係合突起６３を備えている。弾性アーム６２は「へ」字状に形成されており、貫通孔５２の内壁面から後向きに連設されている。差込凹部４３を囲む壁面を構成するカップ部４９には、アームスリット６４が切欠き形成されており、該アームスリット６４に臨んで弾性アーム６２が配置されている。弾性アーム６２のアームスリット６４に臨む部分が解除操作部６０とされて、弾性アーム６２が解除操作部６０を兼ねている。弾性アーム６２は、弾性変形させやすいようにアームスリット６４よりも差込凹部４３の内部寄りに配置されている。各差込凹部４３において、各差込凹部４３の本体部３６の背面中央側の壁面にアームスリット６４が切欠き形成されている。 The first engaging body 58 is composed of a pair of engaging claws 61 integrally formed with the housing 15. The engaging claw 61 is formed in an L shape and projects forward from the bottom wall 16. The L-shaped tip portions of the pair of engaging claws 61 face each other. The second engaging body 59 is provided with a cantilever elastic arm 62 integrally formed with the cover main wall 50 (main body portion 36) and a swinging tip of the elastic arm 62, and the engaging claw 61 is engaged. It includes an engaging protrusion 63 that can be disengaged. The elastic arm 62 is formed in a “he” shape, and is continuously provided backward from the inner wall surface of the through hole 52. An arm slit 64 is notched in the cup portion 49 forming the wall surface surrounding the insertion recess 43, and the elastic arm 62 is arranged so as to face the arm slit 64. The portion of the elastic arm 62 facing the arm slit 64 is the release operation unit 60, and the elastic arm 62 also serves as the release operation unit 60. The elastic arm 62 is arranged closer to the inside of the insertion recess 43 than the arm slit 64 so that it can be easily elastically deformed. In each insertion recess 43, an arm slit 64 is formed in the wall surface on the back center side of the main body portion 36 of each insertion recess 43.

上記のように、保持構造５７の第２係合体５９を係合解除状態に弾性変形させる解除操作部６０を差込凹部４３の壁面に配置すると、第１コネクタ１１に差込み連結された第２コネクタ１２の連結状態を保持する保持構造５７を配線コネクタに設けた場合でも、本体部３６の突出寸法が大きくなることがなく、適正な連結状態を維持しながらも、目立たず、しかも邪魔にならない配線コネクタを得ることができる。
また、差込凹部４３のアームスリット６４に臨んで配置された弾性アーム６２が解除操作部６０を兼ねていると、保持構造５７の係合を解除する解除操作部６０を別途設ける必要がなく、簡素な構造で解除操作部６０を差込凹部４３の内面に配置することができる。また、アームスリット６４を形成したことによって差込凹部４３の壁面に生じた切欠き部は弾性アーム６３で塞がれるので、アームスリット６４を形成したことによる第２コネクタ１２の外観の変化を最小化でき、配線コネクタが目立つようなこともない。 As described above, when the disengaging operation unit 60 that elastically deforms the second engaging body 59 of the holding structure 57 into the disengaged state is arranged on the wall surface of the insertion recess 43, the second connector is inserted and connected to the first connector 11. Even when the holding structure 57 for holding the connected state of 12 is provided in the wiring connector, the protruding dimension of the main body 36 does not become large, and the wiring is inconspicuous and does not get in the way while maintaining the proper connected state. You can get a connector.
Further, when the elastic arm 62 arranged so as to face the arm slit 64 of the insertion recess 43 also serves as the release operation unit 60, it is not necessary to separately provide the release operation unit 60 for disengaging the holding structure 57. With a simple structure, the release operation unit 60 can be arranged on the inner surface of the insertion recess 43. Further, since the notch formed on the wall surface of the insertion recess 43 due to the formation of the arm slit 64 is closed by the elastic arm 63, the change in the appearance of the second connector 12 due to the formation of the arm slit 64 is minimized. The wiring connector does not stand out.

第１コネクタ１１の正面開口１８、ソケット部２０、雌コンタクト１９、および係合爪６１は、正面開口１８の開口中心を対称点として、点対称の関係に形成されている。また、第２コネクタ１２の本体部３６、プラグ部３９、雄コンタクト３８、差込凹部４３、および弾性アーム６２は本体部３６の板面中心を対称点として、点対称の関係に形成されている。このような点対称の関係に各部材を配置することにより、第２コネクタ１２が第１コネクタ１１に対して、導出孔５３が第２コネクタ１２の周端面３７の上周面で開口する標準姿勢と、導出孔５３が第２コネクタ１２の周端面３７の下周面で開口する反転姿勢に差込み連結可能に構成されている。第２コネクタ１２が標準姿勢で連結されているときは給電リード９が上向きに伸び、反転姿勢で連結されているときは給電リード９が下向きに伸びる。これによれば、第２コネクタ１２を差込み連結する姿勢を変更することで、給電リード９を上向きに導出する状態と、下向きに導出する状態とに切り換えることができ、給電リード９の配線形態の自由度を向上して、出力リード９が煩雑に配線されるのを抑制できる。また、煩雑に配線されるのを抑制することで、出力リード９に陳列商品が引っ掛かることがなく、出力リード９の断線のリスクを低減できる。 The front opening 18, the socket portion 20, the female contact 19, and the engaging claw 61 of the first connector 11 are formed in a point-symmetrical relationship with the opening center of the front opening 18 as a point of symmetry. Further, the main body portion 36, the plug portion 39, the male contact 38, the insertion recess 43, and the elastic arm 62 of the second connector 12 are formed in a point-symmetrical relationship with the center of the plate surface of the main body portion 36 as a symmetric point. .. By arranging each member in such a point-symmetrical relationship, the second connector 12 has a standard posture in which the lead-out hole 53 opens on the upper peripheral surface of the peripheral end surface 37 of the second connector 12 with respect to the first connector 11. The lead-out hole 53 is configured to be inserted and connected in an inverted posture that opens on the lower peripheral surface of the peripheral end surface 37 of the second connector 12. When the second connector 12 is connected in the standard posture, the feeding lead 9 extends upward, and when the second connector 12 is connected in the inverted posture, the feeding lead 9 extends downward. According to this, by changing the posture in which the second connector 12 is inserted and connected, it is possible to switch between a state in which the power feeding lead 9 is led out upward and a state in which the power feeding lead 9 is led out downward. The degree of freedom can be improved to prevent the output leads 9 from being complicatedly wired. Further, by suppressing complicated wiring, the display product is not caught on the output lead 9, and the risk of disconnection of the output lead 9 can be reduced.

第１コネクタ１１に対する第２コネクタ１２の連結は、正面開口１８に本体部３６を正対させた状態から、第２コネクタ１２を第１コネクタ１１に向かって差込むことにより行われる。このとき、第２コネクタ１２は、一対の差込凹部４３に指先を差込んで摘んでもよいし、本体部３６の周端面３７の上下、あるいは左右を摘んでもよい。差込み初期のプラグ部３９は、ハウジング１５の上下の周囲壁１７に形成されたガイドリブ６７により、ソケット部２０に対し適正な上下位置に案内される。さらに第２コネクタ１２を差込むと、雄コンタクト３８が、雌コンタクト１９のコンタクト孔２１に進入し、加えて、ソケット部２０に形成されたガイド突起６９が、プラグ部３９の基端ブロック４０に凹み形成されたガイド凹部６８に侵入して案内されながら、雄コンタクト３８と雌コンタクト１９が接続される。保持構造５７は差込み終端で係合されるようになっており、このとき、弾性アーム６２の弾性復元力で、係合爪６１に弾性アーム６２が衝突しカチッと叩打音が生じるので、第２コネクタ１２が適正な位置まで差し込まれたどうかを音で確認できる。 The connection of the second connector 12 to the first connector 11 is performed by inserting the second connector 12 toward the first connector 11 from the state where the main body portion 36 faces the front opening 18. At this time, the second connector 12 may be pinched by inserting a fingertip into the pair of insertion recesses 43, or may pinch the top and bottom or the left and right of the peripheral end surface 37 of the main body 36. The plug portion 39 at the initial stage of insertion is guided to an appropriate vertical position with respect to the socket portion 20 by guide ribs 67 formed on the upper and lower peripheral walls 17 of the housing 15. Further, when the second connector 12 is inserted, the male contact 38 enters the contact hole 21 of the female contact 19, and in addition, the guide protrusion 69 formed in the socket portion 20 enters the base end block 40 of the plug portion 39. The male contact 38 and the female contact 19 are connected while being guided by entering the guide recess 68 formed in the recess. The holding structure 57 is engaged at the insertion end, and at this time, the elastic arm 62 collides with the engaging claw 61 due to the elastic restoring force of the elastic arm 62, and a clicking sound is generated. You can confirm by sound whether the connector 12 is inserted to the proper position.

図１に示すように、ガイド凹部６８は平面視で台形溝状に形成されて、隣り合う雄コンタクト３８の間に配置されており、ガイド突起６９はガイド凹部６８に対応する台形リブ状に形成されて、隣り合う雌コンタクト１９の間に配置されている。両コンタクト１９・３８が接続初期以降において、ガイド突起６９は隣り合う雄コンタクト３８・３８の間に位置するため、ガイド突起６９が隔壁となって、隣り合う雄コンタクト３８・３８どうしの絶縁距離を確保している。このように隔壁として機能するガイド突起６９によって隣り合う雄コンタクト３８・３８どうしが短絡するのを防止できる。また、第２コネクタ１２が差込み終端まで差し込まれた状態では、ガイド凹部６８とガイド突起６９とで、第２コネクタ１２の上下および左右方向の動きが規制されるようになっている。 As shown in FIG. 1, the guide recess 68 is formed in a trapezoidal groove shape in a plan view and is arranged between adjacent male contacts 38, and the guide protrusion 69 is formed in a trapezoidal rib shape corresponding to the guide recess 68. And are located between adjacent female contacts 19. Since the guide protrusions 69 are located between the adjacent male contacts 38 and 38 after the initial connection of both contacts 19 and 38, the guide protrusions 69 serve as a partition wall to provide an insulation distance between the adjacent male contacts 38 and 38. I have secured it. In this way, the guide protrusion 69 that functions as a partition wall can prevent the adjacent male contacts 38 and 38 from being short-circuited. Further, in a state where the second connector 12 is inserted to the insertion end, the movement of the second connector 12 in the vertical and horizontal directions is restricted by the guide recess 68 and the guide protrusion 69.

第２コネクタ１２は、各差込凹部４３に指先を差込み、一対の差込凹部４３間の本体部３６を内向きに摘んだ状態で、手前側に引抜くことにより、第１コネクタ１１から分離できる。このとき、各差込凹部４３において、本体部３６の背面中央側の各差込凹部４３を囲む壁面側に解除操作部６０（弾性アーム６２）が配置されているので、一対の差込凹部４３に指先を差込み、本体部３６を摘まむ動作を行うだけで、意識することなく解除操作部６０で保持構造５７の係合状態を解除できるので、第１コネクタ１１から第２コネクタ１２を分離する動作を簡便化できる。 The second connector 12 is separated from the first connector 11 by inserting a fingertip into each insertion recess 43, pinching the main body 36 between the pair of insertion recesses 43 inward, and pulling it toward the front side. can. At this time, in each of the insertion recesses 43, since the release operation portion 60 (elastic arm 62) is arranged on the wall surface side surrounding each insertion recess 43 on the back center side of the main body portion 36, the pair of insertion recesses 43 The engagement state of the holding structure 57 can be disengaged by the disengaging operation unit 60 without being aware of it by simply inserting a fingertip into the body and pinching the main body 36. Therefore, the second connector 12 is separated from the first connector 11. The operation can be simplified.

上記の実施例以外に、保持構造５７は、第２係合体５９をカップ部４９で左右方向にスライド自在に支持されて、解除操作部を兼ねるスライド体と、スライド体に突出形成される係合リブと、スライド体を係合方向に付勢するばねなどで構成し、第１係合体５８を係合リブがスライド係合される係合溝で構成してもよい。固定構造２９は、ハウジング１５に形成したねじボスと、ねじボスにねじ込まれるビスとで構成でき、この場合には、背面板７の前面側からねじボスにビスをねじ込んで、背面板７に第１コネクタ１１を締結固定する。正面開口１８は真円状、楕円状、多角形状に形成することができる。本体部３６も同様に真円状、楕円状、多角形状に形成することができる。コネクタベース４６とカバー体４７を溶着固定しただけの雄コンタクト３８を備えていない第２コネクタ１２を用意しておき、当該第２コネクタ１２を照明器具４が連結されない第１コネクタ１１に差込み連結することができる。これによれば、不使用の第１コネクタ１１を絶縁しつつ、背面板７上において配線コネクタが目立つのを防止できる。 In addition to the above embodiment, in the holding structure 57, the second engaging body 59 is slidably supported in the left-right direction by the cup portion 49, and the sliding body that also serves as the releasing operation portion is engaged with the slide body so as to project. It may be composed of a rib and a spring or the like for urging the slide body in the engaging direction, and the first engaging body 58 may be composed of an engaging groove in which the engaging rib is slid-engaged. The fixing structure 29 can be composed of a screw boss formed in the housing 15 and a screw screwed into the screw boss. In this case, the screw is screwed into the screw boss from the front side of the back plate 7 and the screw is screwed into the back plate 7. 1 The connector 11 is fastened and fixed. The front opening 18 can be formed in a perfect circular shape, an elliptical shape, or a polygonal shape. Similarly, the main body 36 can be formed into a perfect circle, an ellipse, or a polygon. Prepare a second connector 12 that does not have a male contact 38 that only welds and fixes the connector base 46 and the cover body 47, and inserts and connects the second connector 12 to the first connector 11 to which the lighting fixture 4 is not connected. be able to. According to this, it is possible to prevent the wiring connector from being conspicuous on the back plate 7 while insulating the unused first connector 11.

上記の実施例では、単相３線式の主配線８に合わせて３個のコンタクト対１９・３８を設けたが、単相２線式の主配線８に適用する場合には、左右端のコンタクト対１９・３８だけを設けて主配線８および給電リード９を接続すればよい。中央のコンタクト孔対２１・４２を省略して、単相２線式専用の配線コネクタとすることもできる。また、４個以上のコンタクト対１９・３８を設けることもできる。この場合にも、標準姿勢と反転姿勢で第２コネクタ１２が差込み連結できるように各部材を点対称の関係に形成することが好ましい。ソケット部２０に雄コンタクト３８を設け、プラグ部３９に雌コンタクト１９を設ける形態であってもよい。本実施例に係る配線コネクタはオープン型のショーケースのほか、クローズド型のショーケース、業務用の冷凍冷蔵庫あるいは温蔵庫などの庫内照明装置に電力を供給する配線にも適用できる。 In the above embodiment, three contact pairs 19 and 38 are provided in accordance with the single-phase three-wire main wiring 8, but when applied to the single-phase two-wire main wiring 8, the left and right ends are provided. Only the contact pairs 19 and 38 need to be provided to connect the main wiring 8 and the power supply lead 9. It is also possible to omit the contact hole pairs 21 and 42 in the center and use a wiring connector dedicated to the single-phase two-wire system. It is also possible to provide four or more contact pairs 19.38. Also in this case, it is preferable to form each member in a point-symmetrical relationship so that the second connector 12 can be inserted and connected in the standard posture and the inverted posture. A male contact 38 may be provided in the socket portion 20, and a female contact 19 may be provided in the plug portion 39. The wiring connector according to this embodiment can be applied not only to an open type showcase, but also to a wiring for supplying electric power to an internal lighting device such as a closed type showcase, a commercial refrigerator / freezer or a heat storage.
