次に、主に図３及び図７を参照して、一方のコネクタ部１１の組立てについて説明する。一方のコネクタ部１１の組立ては、まず、コンタクト１２に電線を接続させ、コンタクト１２の先端２７側からハウジング２９の後面４４に形成された挿入口４５にコンタクト１２を挿入させる。コンタクト１２の挿入は、コンタクト１２の接続部２５とは反対側の先端２７側に形成された突起部１９が挿入口４５に形成された狭小部４６を通過するように向きを合わせて行なわれる。そして、挿入口４５から挿入したコンタクト１２をハウジング２９内のコンタクト収容部５０まで押し込み、コンタクト収容部５０に装着させる。 Next, the assembly of one connector portion 11 will be described mainly with reference to FIGS. 3 and 7. In assembling one of the connector portions 11, first, an electric wire is connected to the contact 12, and the contact 12 is inserted into the insertion port 45 formed on the rear surface 44 of the housing 29 from the tip 27 side of the contact 12. The insertion of the contact 12 is performed in such a way that the projection 19 formed on the side of the tip 27 opposite to the connection 25 of the contact 12 passes through the narrow portion 46 formed in the insertion port 45. Then, the contact 12 inserted from the insertion port 45 is pushed to the contact accommodating portion 50 in the housing 29 and mounted on the contact accommodating portion 50.

このとき、コンタクト収容部５０に押し込まれたコンタクト１２は、コンタクト１２の底部１４に形成された固定孔１５にコンタクト収容部５０の底面３９側に形成された固定片５１が嵌り込むことで位置決め固定され、装着される。このとき、固定片５１は、コンタクト１２の底部１４の先端２７側に押されることで弾性変形してコンタクト１２の底部１４を摺動し、その後、固定片５１が固定孔１５に嵌り込むことで、弾性力が開放され、固定孔１５と固定片５１が係合され、コンタクト１２の抜け止めがされる。同様に、他のコンタクト１２をハウジング２９への装着を行なうことで、一方のコネクタ部１１が組立てられる。 At this time, the contact 12 pushed into the contact accommodating portion 50 is positioned and fixed by fitting the fixing piece 51 formed on the bottom surface 39 side of the contact accommodating portion 50 into the fixing hole 15 formed in the bottom portion 14 of the contact 12 And be worn. At this time, the fixing piece 51 is elastically deformed by being pushed toward the tip 27 side of the bottom portion 14 of the contact 12 and slides on the bottom portion 14 of the contact 12, and then the fixing piece 51 is fitted into the fixing hole 15. The elastic force is released, the fixing hole 15 and the fixing piece 51 are engaged, and the contact 12 is prevented from coming off. Similarly, by mounting the other contact 12 to the housing 29, one connector portion 11 is assembled.

なお、他方のコネクタ部１１Ａの組立ては、一方のコネクタ部１１の組立てと共通するので、詳細な説明は省略する。 In addition, since the assembly of the other connector part 11A is the same as the assembly of one connector part 11, detailed description will be omitted.

次に、一方のコネクタ部１１と他方のコネクタ部１１Ａの接続について説明する。一方のコネクタ部１１と他方のコネクタ部１１Ａの接続は、まず、図１Ａ、図２Ａ、図２Ｂ及び図７Ａに示すように、他方のコネクタ部１１Ａを一方のコネクタ部１１に対して、上下及び左右を反転した状態、すなわち、一方のコネクタ部１１のハウジング２９及び他方のコネクタ部１１Ａのハウジング２９Ａの接続方向側となる各前面４０、４０Ａを向かい合わせ、且つ、一方のコネクタ部１１に対して、他方のコネクタ部１１Ａの上面３０Ａと底面３９Ａの位置が一方のコネクタ部１１と反対となるように配置される。 Next, the connection between one connector portion 11 and the other connector portion 11A will be described. First, as shown in FIG. 1A, FIG. 2A, FIG. 2B and FIG. 7A, the connection between one connector portion 11 and the other connector portion 11A is made up and down and the other connector portion 11A with respect to one connector portion 11. A state in which the left and right are reversed, that is, the front faces 40 and 40A on the connection direction side of the housing 29 of one connector portion 11 and the housing 29A of the other connector portion 11A face each other, and with respect to one connector portion 11 The positions of the top surface 30A and the bottom surface 39A of the other connector portion 11A are arranged so as to be opposite to that of the one connector portion 11.

次に、向かい合わせた状態の一方のコネクタ部１１及び他方のコネクタ部１１Ａの各上面３０、３０Ａの各下段面３２、３２Ａを近接させ、一方のコネクタ部１１の前面４０の当接部４３と他方のコネクタ部１１Ａの上面３０Ａの壁面部３３Ａ、及び他方のコネクタ部１１Ａの前面４０Ａの当接部４３Ａと一方のコネクタ部１１の上面３０の壁面部３３とがそれぞれ当接するまで移動される（図１Ｂ、図２Ｃ、図２Ｄ及び図７Ｂ参照）。 Next, the lower surfaces 32 and 32A of the upper surfaces 30 and 30A of one connector portion 11 and the other connector portion 11A in the opposite state are made to approach each other, and the contact portion 43 of the front surface 40 of one connector portion 11 The wall surface portion 33A of the upper surface 30A of the other connector portion 11A, the contact portion 43A of the front surface 40A of the other connector portion 11A, and the wall surface portion 33 of the upper surface 30 of the one connector portion 11 respectively move 1B, 2C, 2D and 7B).

このとき、一方のコネクタ部１１と他方のコネクタ部１１Ａの各下段面３２、３２Ａが近接することで、一方のコネクタ部１１の下段面３２から突出したコンタクト１２の接触部２２の接触面２３ａと、他方のコネクタ部１１Ａの下段面３２Ａから突出したコンタクト１２Ａの接触部２２Ａの接触面２３Ａａとが互に接触される。その際、一方のコネクタ部１１のコンタクト１２の接触部２２の接触片２３と、他方のコネクタ部１１Ａのコンタクト１２Ａの接触部２２Ａの接触片２３Ａとがそれぞれ弾性変形される（図７Ｂ参照）。 At this time, the contact surfaces 23a of the contact portions 22 of the contacts 12 protruding from the lower surface 32 of the one connector portion 11 and the lower surfaces 32 and 32A of the other connector portion 11A approach each other. The contact surface 23Aa of the contact portion 22A of the contact 12A protruding from the lower surface 32A of the other connector portion 11A contacts each other. At that time, the contact piece 23 of the contact portion 22 of the contact 12 of one connector portion 11 and the contact piece 23A of the contact portion 22A of the contact 12A of the other connector portion 11A are elastically deformed (see FIG. 7B).

また、一方のコネクタ部１１と他方のコネクタ部１１Ａが接続方向に移動される際に、一方のコネクタ部１１に形成された嵌合突起３４が他方のコネクタ部１１Ａに形成された嵌合孔４１Ａに嵌合され、他方のコネクタ部１１Ａに形成された嵌合突起３４Ａが一方のコネクタ部１１に形成された嵌合孔４１に嵌合されるようになる。そして、この嵌合突起３４、３４Ａが嵌合孔４１、４１Ａにそれぞれ嵌合されることで、一方のコネクタ部１１及び他方のコネクタ部１１Ａの接続の際の移動が案内され、円滑に接続を行なうことができるようになる（図８参照）。 Also, when one connector portion 11 and the other connector portion 11A are moved in the connection direction, a fitting hole 41A is formed in the other connector portion 11A with the fitting protrusion 34 formed on the one connector portion 11 And the fitting projection 34A formed on the other connector 11A is fitted in the fitting hole 41 formed on the one connector 11. Then, by fitting the fitting projections 34, 34A into the fitting holes 41, 41A, respectively, movement at the time of connection of one connector portion 11 and the other connector portion 11A is guided, and the connection is smoothly performed. It can be done (see Figure 8).

その後、一方のコネクタ部１１と他方のコネクタ部１１Ａを接続方向に移動させ、一方のコネクタ部１１のハウジング２９の前面４０の当接部４３と他方のコネクタ部１１Ａのハウジング２９Ａの壁面部３３Ａが当接され、また、他方のコネクタ部１１Ａのハウジング２９Ａの前面４０Ａの当接部４３Ａと一方のコネクタ部１１のハウジング２９の壁面部３３が当接されと、一方のコネクタ部１１と他方のコネクタ部１１Ａとが接続され、ロック機構５２により接続が固定される。 Thereafter, one connector portion 11 and the other connector portion 11A are moved in the connecting direction, and the contact portion 43 of the front surface 40 of the housing 29 of the one connector portion 11 and the wall surface portion 33A of the housing 29A of the other connector portion 11A When the contact portion 43A of the front surface 40A of the housing 29A of the other connector portion 11A and the wall surface portion 33 of the housing 29 of the one connector portion 11 abut each other, the one connector portion 11 and the other connector The connection is fixed by the lock mechanism 52.

このロック機構５２による接続の固定は、図８に示すように、一方のコネクタ部１１のハウジング２９の各嵌合突起３４に形成された係止突起３５と、他方のコネクタ部１１Ａのハウジング２９Ａの下段面３２Ａの各嵌合孔４１Ａを覆うように形成された係止部３８Ａが係止され、また、他方のコネクタ部１１Ａのハウジング２９Ａの各嵌合突起３４Ａの形成された各係止突起３５Ａと、一方のコネクタ部１１のハウジング２９の下段面３２の各嵌合孔４１を覆うように形成された各係止部３８がそれぞれ係止されることにより行なわれる。以上により、一方のコネクタ部１１と他方のコネクタ部１１Ａの接続が完了する。 The fixation of the connection by the lock mechanism 52 is, as shown in FIG. 8, of the locking projections 35 formed on the respective fitting projections 34 of the housing 29 of one of the connector portions 11 and the housing 29A of the other connector portion 11A. Locking portions 38A formed to cover the fitting holes 41A of the lower surface 32A are locked, and locking protrusions 35A formed with the fitting protrusions 34A of the housing 29A of the other connector portion 11A. The locking portions 38 formed to cover the fitting holes 41 of the lower surface 32 of the housing 29 of the one connector portion 11 are locked. By the above, the connection of one connector part 11 and the other connector part 11A is completed.

このように、実施形態のロック機構５２は、一方のコネクタ部１１側のハウジング２９に形成された２つの嵌合突起３４と、他方のコネクタ部１１Ａ側のハウジング２９Ａに形成された２つの係止部３８Ａ、及び他方のコネクタ部１１Ａ側のハウジング２９Ａに形成された２つの係止突起３５Ａと、一方のコネクタ部１１側のハウジング２９に形成された２つの係止部３８とがそれぞれ係止されることで、一方のコネクタ部と他方のコネクタ部の接続が４箇所で固定されるようになり、確実に固定を維持することができる。 Thus, the lock mechanism 52 according to the embodiment includes two fitting projections 34 formed on the housing 29 on one connector portion 11 and two locks formed on the housing 29A on the other connector portion 11A. The two locking projections 35A formed on the housing 38A on the side of the other portion 38A and the other connector 11A and the two locking portions 38 formed on the housing 29 on the side of one connector 11 are respectively locked By this, the connection between one connector portion and the other connector portion is fixed at four points, and the fixing can be reliably maintained.

また、各係止突起３５、３５Ａは各嵌合突起３４、３４Ａに、各係止部３８、３８Ａは嵌合孔４１、４１Ａを覆うようにそれぞれ形成されているので、各嵌合突起３４、３４Ａと各嵌合孔４１、４１Ａの嵌合と、各係止突起３５、３５Ａと各係止部３８、３８Ａの係止を同一工程で行なうことができる。 Further, since the locking projections 35 and 35A are formed on the fitting projections 34 and 34A, and the locking portions 38 and 38A are formed to cover the fitting holes 41 and 41A, the fitting projections 34 and 35A are formed. The fitting of the fitting holes 34 and the fitting holes 41 and 41A and the locking of the locking projections 35 and 35A and the locking portions 38 and 38A can be performed in the same process.

また、一方のコネクタ部１１及び他方のコネクタ部１１Ａは、各嵌合突起３４、３４Ａが嵌合孔４１、４１Ａに嵌合されることで、各ハウジング２９、２９Ａの下段面３２、３２Ａが近接し、各コネクタが離れる方向に移動することが規制されるため、各コンタクト１２の接触片２３は、互いの弾性力によりそれぞれ押圧し合い、確実に接触が行なわれる。 Further, in the one connector portion 11 and the other connector portion 11A, the lower surfaces 32, 32A of the respective housings 29, 29A are close to each other by the respective fitting projections 34, 34A being fitted in the fitting holes 41, 41A. Since the movement of the connectors in the direction away from each other is restricted, the contact pieces 23 of the contacts 12 are mutually pressed by the elastic force of each other, and the contacts are reliably made.

また、一方のコネクタ部１１と他方のコネクタ部１１Ａは、それぞれのハウジング２９、２９Ａ、及びそれぞれに装着されるコンタクト１２、１２Ａが同じ形状で形成された雌雄同型のコネクタで構成されているので、製造される部品点数を削減することができる。また、ロック機構についても、雌雄同型のハウジングで形成することができる。 In addition, since one connector portion 11 and the other connector portion 11A are configured as male-female connectors in which the respective housings 29, 29A and the contacts 12, 12A mounted on the respective housings 29, 29A are formed in the same shape, The number of parts manufactured can be reduced. In addition, the locking mechanism can also be formed by a male and female housing.

なお、実施形態では、一方のコネクタ部及び他方のコネクタ部には、それぞれ４本のコンタクトが装着される場合を説明したがこれに限らず、各１本ずつを用いた場合でもよく、また、コンタクトが幅方向に並列されていれば、４本以外に複数の本数を用いることができる。 In the embodiment, the case where four contacts are attached to each of the one connector portion and the other connector portion is described, but the present invention is not limited to this. If the contacts are arranged in parallel in the width direction, a plurality of numbers other than four can be used.

なお、一方のコネクタ部がコネクタ部と対応し、他方のコネクタ部が相手方コネクタ部と対応する。 One connector part corresponds to the connector part, and the other connector part corresponds to the other connector part.
