Description

本発明は、例えば携帯電話機用の充電式電池を携帯電話機本体側と電気的に接続するためのコネクタに関するものである。 The present invention relates to a connector for electrically connecting, for example, a rechargeable battery for a mobile phone to the mobile phone body side.

一般に、携帯電話機の本体背面側には、充電式電池からなるバッテリーが着脱自在に取付けられており、バッテリーの接点には携帯電話機本体側に設けられたコネクタが接触することにより、バッテリーと携帯電話機本体がコネクタを介して電気的に接続されるようになっている（例えば、特許文献１参照。）。 In general, a battery made of a rechargeable battery is detachably attached to the back side of the main body of the mobile phone, and the battery and the mobile phone are brought into contact with a battery contact by a connector provided on the mobile phone main body side. The main body is electrically connected via a connector (see, for example, Patent Document 1).

前記コネクタは、バッテリー等の接続対象物と接触する弾性変形可能な複数の端子と、各端子を保持する絶縁性のコネクタ本体とを備え、各端子の一端側をコネクタ本体内に固定するとともに、各端子の他端側をコネクタ本体の一端側の面から外部に突出させ、接続対象物をコネクタ本体の所定方向から端子の他端側に接触させることにより、各端子をコネクタ本体側に弾性変形させて接続対象物の電気接点に圧接させるように構成されている（例えば、特許文献２参照。）。 The connector includes a plurality of elastically deformable terminals that come into contact with a connection object such as a battery, and an insulating connector body that holds each terminal, and fixes one end of each terminal in the connector body, Each terminal is elastically deformed to the connector body side by projecting the other end side of each terminal to the outside from the surface of one end side of the connector body and bringing the connection object into contact with the other end side of the terminal from a predetermined direction of the connector body. It is comprised so that it may be made to press-contact to the electrical contact of a connection target object (for example, refer patent document 2).

しかしながら、前記コネクタでは、係止片１ａの先端がコネクタ本体２の内面に接触するため、係止片１ａの先端によってコネクタ本体２の内面が削れ、コネクタ本体２の品質を低下させるという問題点があった。また、係止片１ａの先端がコネクタ本体２の内面に突き刺さり易いため、端子１の円滑な動作が妨げられるとともに、係止片１ａが突き刺さった状態で外力が加わることにより係止片１ａの変形を生ずるという問題点もあった。 However, in the connector, since the tip of the locking piece 1a contacts the inner surface of the connector body 2, the inner surface of the connector body 2 is scraped by the tip of the locking piece 1a, and the quality of the connector body 2 is deteriorated. there were. Further, since the tip of the locking piece 1a is likely to pierce the inner surface of the connector main body 2, the smooth operation of the terminal 1 is hindered, and deformation of the locking piece 1a is caused by external force being applied while the locking piece 1a is pierced. There was also a problem of producing.

本発明は前記問題点に鑑みてなされたものであり、その目的とするところは、端子の係止片がコネクタ本体の内面に接触しても、係止片によってコネクタ本体が削れることがなく、しかも端子の動作も円滑に行うことができ、係止片の変形も生ずることのないコネクタを提供することにある。 The present invention has been made in view of the above problems, and the purpose thereof is to prevent the connector body from being scraped by the locking piece even if the locking piece of the terminal contacts the inner surface of the connector body. In addition, it is an object of the present invention to provide a connector that can smoothly operate the terminal and that does not cause deformation of the locking piece.

本発明は前記目的を達成するために、接続対象物と接触する弾性変形可能な端子と、端子を保持する絶縁性のコネクタ本体とを備え、端子の一端側をコネクタ本体内に固定し、端子の他端側をコネクタ本体の一端側の面に設けた開口部から外部に突出させるとともに、端子の幅方向両側に設けた係止片をコネクタ本体の一端側の内面に係止することにより、端子の変位を所定位置で規制するようにしたコネクタにおいて、前記係止片を、端子の他端に設けられた第１の係止片と、端子の一端側と他端側との間に設けられた第２の係止片とから形成し、接続対象物と接触する接触部を第１の係止片と第２の係止片との間に設け、第２の係止片をコネクタ本体の一端側の内面に接触する部分が曲面状をなすように形成している。 In order to achieve the above object, the present invention includes an elastically deformable terminal that comes into contact with an object to be connected and an insulating connector main body that holds the terminal, and fixes one end of the terminal in the connector main body. The other end side of the connector body protrudes to the outside from the opening provided on the one end side surface of the connector body, and the locking pieces provided on both sides in the width direction of the terminal are locked to the inner surface on the one end side of the connector body, In the connector in which the displacement of the terminal is restricted at a predetermined position, the locking piece is provided between the first locking piece provided at the other end of the terminal and the one end side and the other end side of the terminal. A contact portion that is in contact with an object to be connected is provided between the first locking piece and the second locking piece, and the second locking piece is connected to the connector main body. The part which contacts the inner surface of the one end side is formed so as to form a curved surface.

これにより、第２の係止片におけるコネクタ本体の内面との接触部分が曲面状をなすように形成されていることから、第２の係止片の接触によってコネクタ本体の内面が削れたり、第２の係止片がコネクタ本体の内面に突き刺さることがない。また、コネクタ本体の一端側の内面に端子の第１の係止片及び第２の係止片が係止することにより、コネクタ本体の一端側への端子の変位が所定位置で規制される。 Accordingly, since the contact portion between the inner surface of the connector body of the second locking piece is formed so as to form a curved, or shaved inner surface of the connector body by contact of the second locking piece, the The two locking pieces do not pierce the inner surface of the connector body. In addition, when the first locking piece and the second locking piece of the terminal are locked to the inner surface of one end side of the connector body, the displacement of the terminal toward the one end side of the connector body is restricted at a predetermined position.

本発明のコネクタによれば、第２の係止片の接触によってコネクタ本体の内面が削れることがないので、コネクタ本体の品質を低下させることがないという利点がある。この場合、第２の係止片がコネクタ本体の内面に突き刺さることもないので、端子を常に円滑に動作させることができるとともに、第２の係止片が突き刺さった状態で外力が加わることもないので、第２の係止片の変形を確実に防止することができる。また、端子の第１の係止片及び第２の係止片により、コネクタ本体の一端側への端子の変位を所定位置で規制することができるので、端子の不適正な方向への変形を防止することができる。 According to the connector of the present invention, since the inner surface of the connector main body is not scraped by the contact of the second locking piece, there is an advantage that the quality of the connector main body is not deteriorated. In this case, since the second locking piece does not pierce the inner surface of the connector main body, the terminal can be operated smoothly at all times, and no external force is applied when the second locking piece is pierced. Therefore, deformation of the second locking piece can be reliably prevented. Moreover, since the displacement of the terminal toward the one end side of the connector main body can be restricted at a predetermined position by the first locking piece and the second locking piece of the terminal, the terminal is deformed in an inappropriate direction. Can be prevented.

コネクタ本体１０は合成樹脂の成形品からなり、各端子２０が配置される複数の端子孔１１を幅方向に間隔をおいて有している。各端子孔１１はコネクタ本体１０の前面（一端側の面）及び下面に開口しており、その上面側及び背面側（コネクタ本体１０の他端側の面側）はコネクタ本体１０の上面壁１２及び背面壁１３によって囲まれている。この場合、端子孔１１の前面側開口部１１ａは端子孔１１の内部よりも幅寸法が小さく形成されている。また、コネクタ本体１０の前面には各端子孔１１の幅方向両側から前方に突出する複数の突出部１４が設けられている。コネクタ本体１０内には背面壁１３に沿って上下方向に延びる端子保持溝１５が設けられ、端子保持溝１５は端子孔１１の幅方向両面に設けられている。即ち、端子保持溝１５に端子２０の一端側を下方から圧入することにより、端子２０がコネクタ本体１０に保持されるようになっている。また、コネクタ本体１０の底面には金属製の複数の固定部材１６が互いに幅方向に間隔をおいて取付けられており、各固定部材１６は図示しない基板に半田付け等により固定されるようになっている。 The connector body 10 is made of a synthetic resin molded product, and has a plurality of terminal holes 11 in which the terminals 20 are arranged at intervals in the width direction. Each terminal hole 11 opens to the front surface (one end side surface) and the lower surface of the connector main body 10, and the upper surface side and rear surface side (the other surface side of the connector main body 10) are the upper surface wall 12 of the connector main body 10. And the back wall 13. In this case, the front side opening 11 a of the terminal hole 11 is formed to have a width dimension smaller than the inside of the terminal hole 11. In addition, a plurality of projecting portions 14 projecting forward from both sides in the width direction of the terminal holes 11 are provided on the front surface of the connector body 10. In the connector main body 10, terminal holding grooves 15 extending in the vertical direction along the back wall 13 are provided, and the terminal holding grooves 15 are provided on both sides of the terminal hole 11 in the width direction. That is, the terminal 20 is held by the connector body 10 by press-fitting one end side of the terminal 20 into the terminal holding groove 15 from below. Further, a plurality of metal fixing members 16 are attached to the bottom surface of the connector body 10 at intervals in the width direction, and each fixing member 16 is fixed to a substrate (not shown) by soldering or the like. ing.

各端子２０はその一部を略Ｓ字状に形成された弾性変形可能な導電性の金属板からなり、その一端側はコネクタ本体１０に固定されている。端子２０は、コネクタ本体１０の背面壁１３に沿って上下方向に延びる第１の平板部２１と、第１の平板部２１の上端から下方に向かって屈曲する第１の屈曲部２２と、第１の屈曲部２２から下方に延びる第２の平板部２３と、第２の平板部２３の下端から斜め上方に向かって屈曲する第２の屈曲部２４と、第２の屈曲部２４から上方に延びる第３の平板部２５と、第３の平板部２５の上端から斜め下方に向かって屈曲する第３の屈曲部２６と、第３の屈曲部２６からコネクタ本体１０の前面を介して前方に前下りに延びる第４の平板部２７と、第４の平板部２７の前端から後方に向かって屈曲する接触部２８と、接触部２８から後方に延びる第５の平板部２９とから形成され、第１の平板部２１の下端には図示しない基板等に接続される接続部２１ａが設けられている。即ち、端子２０は、略Ｓ字状部分の各屈曲部２２，２４，２６を基点に接続対象物の接触方向（前後方向）に変形するようになっている。また、第５の平板部２９の下端にはコネクタ本体１０の前面側の内面に係止する第１の係止片２９ａが設けられ、各第１の係止片２９ａは端子孔１１の前面側開口部１１ａよりも幅が広くなるように幅方向外側に向かって延出している。第３の平板部２５の上端側の幅方向両側にはコネクタ本体１０の前面側の内面に係止する第２の係止片２５ｂがそれぞれ設けられ、各第２の係止片２５ｂは端子孔１１の前面側開口部１１ａよりも幅が広くなるように形成されている。この場合、各第２の係止片２５ｂは上方に向かって延出するとともに、コネクタ本体１０の内面との接触部分が曲面状をなすように後方に向かって屈曲している。 Each terminal 20 is made of an elastically deformable conductive metal plate partly formed in a substantially S shape, and one end side thereof is fixed to the connector main body 10. The terminal 20 includes a first flat plate portion 21 extending in the vertical direction along the back wall 13 of the connector body 10, a first bent portion 22 bent downward from the upper end of the first flat plate portion 21, A second flat plate portion 23 extending downward from one bent portion 22, a second bent portion 24 bent obliquely upward from the lower end of the second flat plate portion 23, and upward from the second bent portion 24. A third flat plate portion 25 that extends, a third bent portion 26 that bends obliquely downward from the upper end of the third flat plate portion 25, and a front portion of the connector main body 10 from the third bent portion 26 forward. Formed from a fourth flat plate portion 27 extending forward and downward, a contact portion 28 bent rearward from the front end of the fourth flat plate portion 27, and a fifth flat plate portion 29 extending backward from the contact portion 28, The lower end of the first flat plate portion 21 is connected to a substrate or the like (not shown). Part 21a is provided. That is, the terminal 20 is configured to be deformed in the contact direction (front-rear direction) of the connection object with the bent portions 22, 24, 26 of the substantially S-shaped portion as the base point. The lower end of the fifth flat plate portion 29 is provided with a first locking piece 29a that is locked to the inner surface on the front surface side of the connector body 10, and each first locking piece 29a is on the front side of the terminal hole 11. It extends toward the outside in the width direction so as to be wider than the opening 11a. On both sides in the width direction on the upper end side of the third flat plate portion 25, second locking pieces 25b that are locked to the inner surface on the front surface side of the connector main body 10 are provided, and each second locking piece 25b has a terminal hole. 11 is formed so as to be wider than the front opening 11a. In this case, each second locking piece 25b extends upward, and is bent rearward so that the contact portion with the inner surface of the connector body 10 forms a curved surface.

以上のように構成されたコネクタは、例えば携帯電話機におけるバッテリー収納部の基板に取付けられる。即ち、接続対象物としてのバッテリー（図示せず）が端子２０の接触部２８に接触すると、図３の一点鎖線に示すように端子２０がコネクタ本体１０の後方に向かって変形し、バッテリーの接触が解除されると、端子２０の弾性により接触部２８が前方に戻る。また、コネクタ本体１０の前面側の内面に端子２０の第１の係止片２９ａ及び第２の係止片２５ｂが係止することにより、端子２０の前方への変位が所定位置で規制され、端子２０の不適正な方向への変形が防止される。この場合、第２の係止片２５ｂは、コネクタ本体１０の内面との接触部分が曲面状をなすように形成されていることから、第２の係止片２５ｂの接触によってコネクタ本体１０の内面が削れたり、第２の係止片２５ｂがコネクタ本体１０の内面に突き刺さることがない。 The connector configured as described above is attached to a substrate of a battery storage unit in a mobile phone, for example. That is, when a battery (not shown) as a connection object comes into contact with the contact portion 28 of the terminal 20, the terminal 20 is deformed toward the rear of the connector body 10 as shown by an alternate long and short dash line in FIG. When is released, the contact portion 28 returns to the front due to the elasticity of the terminal 20. Further, the first locking piece 29a and the second locking piece 25b of the terminal 20 are locked to the inner surface on the front side of the connector body 10, whereby the forward displacement of the terminal 20 is restricted at a predetermined position. Deformation of the terminal 20 in an inappropriate direction is prevented. In this case, the second locking piece 25b is formed so that the contact portion with the inner surface of the connector main body 10 forms a curved surface, and therefore the inner surface of the connector main body 10 by the contact of the second locking piece 25b. The second locking piece 25b is not pierced into the inner surface of the connector body 10.

このように、本実施形態のコネクタによれば、コネクタ本体１０の内面に係止する第２の係止片２５ｂをコネクタ本体１０の内面との接触部分が曲面状をなすように形成したので、第２の係止片２５ｂの接触によってコネクタ本体１０の内面が削れることがなく、コネクタ本体１０の品質を低下させることがないという利点がある。この場合、第２の係止片２５ｂがコネクタ本体１０の内面に突き刺さることもないので、端子２０を常に円滑に動作させることができるとともに、第２の係止片２５ｂが突き刺さった状態で外力が加わることもないので、第２の係止片２５ｂの変形を確実に防止することができる。 Thus, according to the connector of the present embodiment, the second locking piece 25b that locks to the inner surface of the connector body 10 is formed so that the contact portion with the inner surface of the connector body 10 forms a curved surface. There is an advantage that the inner surface of the connector main body 10 is not scraped by the contact of the second locking piece 25b, and the quality of the connector main body 10 is not deteriorated. In this case, since the second locking piece 25b does not pierce the inner surface of the connector body 10, the terminal 20 can always be operated smoothly, and an external force can be applied while the second locking piece 25b is pierced. Since it is not added, the deformation | transformation of the 2nd locking piece 25b can be prevented reliably.

また、第２の係止片２５ｂをコネクタ本体１０の後方に向かって屈曲させることにより曲面状に形成するようにしたので、第２の係止片２５ｂを曲げ加工により容易に形成することができ、製造上極めて有利である。 Further, since the second locking piece 25b is formed in a curved shape by bending it toward the rear of the connector body 10, the second locking piece 25b can be easily formed by bending. It is extremely advantageous in manufacturing.
