JP 2006-147271 A

しかしながら、このコネクタでは、回動部材を閉鎖したときにロック部材が接続対象物の切欠部に嵌合して接続対象物を反挿入方向に係止するようになっているので、接続対象物の挿入時には接続対象物をどの位置まで挿入すればよいのか確認することができず、接続対象物がコネクタ本体に完全に挿入されていない状態で各端子と接続対象物が電気的に接続する場合がある。このとき、回動部材を閉鎖する前に接続対象物がコネクタ本体から抜け出したり、接続対象物と各端子との間に位置ずれが生じて接触不良になるという問題点があった。   However, in this connector, when the rotating member is closed, the lock member is fitted into the cutout portion of the connection object, and the connection object is locked in the anti-insertion direction. At the time of insertion, it cannot be confirmed to what position the connection object should be inserted, and each terminal and the connection object may be electrically connected in a state where the connection object is not completely inserted into the connector body. is there. At this time, there is a problem that the connection object comes out of the connector main body before closing the rotating member, or a positional shift occurs between the connection object and each terminal, resulting in poor contact.

前記コネクタにおいては、図７（ａ）及び図７（ｂ）に示すように押圧カバー４０を開放方向、即ち前方に回動すると、全開位置（全閉位置から約９０°回動させた位置）において押圧カバー４０の後端側が各端子２０，３０の係合部２１ｂ，３１ｂに係合する。その際、各端子２０，３０の弾性片部２１，３１の後端側が押圧カバー４０によって下方に押圧され、各端子２０，３０の弾性片部２１，３１の前端側が上昇する。このとき、各第１の端子２０（各第２の端子３０についても同様）の第１の接触部２１ａ及び第２の接触部２２ａ間の上下方向の寸法Ｄ２がフレキシブル回路１の厚さ寸法より大きくなり、フレキシブル回路１をコネクタ本体１０に挿入することが可能となる。   In the connector, as shown in FIGS. 7A and 7B, when the pressing cover 40 is rotated in the opening direction, that is, forward, the fully open position (position rotated about 90 ° from the fully closed position). , The rear end side of the pressing cover 40 is engaged with the engaging portions 21 b and 31 b of the terminals 20 and 30. At this time, the rear end sides of the elastic pieces 21 and 31 of the terminals 20 and 30 are pressed downward by the pressing cover 40, and the front end sides of the elastic pieces 21 and 31 of the terminals 20 and 30 are raised. At this time, the vertical dimension D2 between the first contact portion 21a and the second contact portion 22a of each first terminal 20 (same for each second terminal 30) is larger than the thickness dimension of the flexible circuit 1. As a result, the flexible circuit 1 can be inserted into the connector body 10.

次に、図８（ａ）に示すようにフレキシブル回路１をコネクタ本体１０に挿入すると、フレキシブル回路１の先端の幅方向両端側が各ロック端子５０の係止部５２ａに当接する。そして、図８（ｂ）に示すようにフレキシブル回路１をさらにコネクタ本体１０の後方に向かって挿入すると、各ロック端子５０の弾性片５２が下方に弾性変形する。この場合、係止部５２ａは、その前端部がフレキシブル回路１の下面に当接しながら、フレキシブル回路１をコネクタ本体１０の後方に案内するようになっている。さらに、図８（ｃ）に示すようにフレキシブル回路１をコネクタ本体１０の後方に向かって挿入すると、各ロック端子５０の係止部５２ａは、上方に復元しながらフレキシブル回路１の各切欠部１ｃに嵌合する。このとき、係止部５２ａがフレキシブル回路１の各切欠部１ｃに嵌合する感触がフレキシブル回路１を介して外部に伝わる。また、各ロック端子５０の係止部５２ａは、フレキシブル回路１の各切欠部１ｃに嵌合すると、フレキシブル回路１の反挿入方向、即ち前方への移動を規制する。   Next, as shown in FIG. 8A, when the flexible circuit 1 is inserted into the connector body 10, both ends in the width direction of the distal end of the flexible circuit 1 abut against the locking portions 52 a of the lock terminals 50. When the flexible circuit 1 is further inserted toward the rear of the connector main body 10 as shown in FIG. 8B, the elastic pieces 52 of the lock terminals 50 are elastically deformed downward. In this case, the locking portion 52 a guides the flexible circuit 1 to the rear of the connector body 10 while the front end of the locking portion 52 a is in contact with the lower surface of the flexible circuit 1. Further, when the flexible circuit 1 is inserted toward the rear of the connector body 10 as shown in FIG. 8C, the locking portions 52a of the lock terminals 50 are restored upward and the notches 1c of the flexible circuit 1 are restored. To fit. At this time, a feeling that the engaging portion 52 a is fitted in each notch portion 1 c of the flexible circuit 1 is transmitted to the outside through the flexible circuit 1. Moreover, when the latching | locking part 52a of each lock terminal 50 fits in each notch part 1c of the flexible circuit 1, the movement to the anti-insertion direction of the flexible circuit 1, ie, the front, is controlled.

そして、係止部５２ａがフレキシブル回路１の各切欠部１ｃに嵌合した後に押圧カバー４０を閉鎖方向に回動すると、各第１の端子２０は、図９（ａ）に示すように押圧カバー４０による押圧が解除されることにより復元する。この場合、弾性片部２１の第１の接触部２１ａが下方に移動して、フレキシブル回路１の第１の電気接点１ａに接触する。また、図９（ｂ）に示すように、各第２の端子３０の第１の接触部３１ａは、下方に移動してフレキシブル回路１の第２の電気接点１ｂに接触する。これにより、フレキシブル回路１と基板Ａとが各端子２０，３０を介して電気的に接続される。なお、押圧カバー４０を閉鎖したときには、押圧カバー４０の各第１の当接部４１ａが各第１の端子２０の弾性片部２１の下面後端側に当接するとともに、各第２の当接部４２ｂが各第２の端子３０の弾性片部３１の下面後端側に当接する。これにより、弾性片部２１，３１の弾性変形が規制されることから、各端子２０，３０第１の接触部２１ａ，３１ａがフレキシブル回路１から離間して接触不良となることがない。   Then, when the pressing cover 40 is rotated in the closing direction after the locking portion 52a is fitted in each notch portion 1c of the flexible circuit 1, each first terminal 20 is pressed against the pressing cover as shown in FIG. It restores by releasing the press by 40. In this case, the first contact portion 21 a of the elastic piece portion 21 moves downward and contacts the first electrical contact 1 a of the flexible circuit 1. Further, as shown in FIG. 9B, the first contact portion 31 a of each second terminal 30 moves downward and contacts the second electrical contact 1 b of the flexible circuit 1. Thereby, the flexible circuit 1 and the board | substrate A are electrically connected via each terminal 20 and 30. FIG. When the pressing cover 40 is closed, each first contact portion 41a of the pressing cover 40 contacts the lower surface rear end side of the elastic piece portion 21 of each first terminal 20, and each second contact. The part 42b contacts the lower surface rear end side of the elastic piece part 31 of each second terminal 30. Thereby, since elastic deformation of the elastic piece portions 21 and 31 is restricted, the first contact portions 21a and 31a of the terminals 20 and 30 are not separated from the flexible circuit 1 to cause poor contact.

また、図９（ｃ）に示すように各ロック端子５０の規制部５２ｂの下面には、押圧カバー５０の基端側が当接していることから、規制部５２ｂの下方への移動が規制される。この場合、係止部５２ａの下方への移動も規制されることから、押圧カバー４０の閉鎖時には端子５０の係止部５２ａをフレキシブル回路１の切欠部１ｃに常に嵌合させることができ、フレキシブル回路１を確実に係止することが可能となる。   Further, as shown in FIG. 9C, since the base end side of the pressing cover 50 is in contact with the lower surface of the restricting portion 52b of each lock terminal 50, the downward movement of the restricting portion 52b is restricted. . In this case, since the downward movement of the locking portion 52a is also restricted, the locking portion 52a of the terminal 50 can always be fitted into the cutout portion 1c of the flexible circuit 1 when the pressing cover 40 is closed. The circuit 1 can be reliably locked.

このように、本実施形態のコネクタによれば、ロック端子５０をコネクタ本体１０の端子配列方向両端側に備え、ロック端子５０には、コネクタ本体１０に挿入されたフレキシブル回路１の下面に接触しながら弾性変形し、フレキシブル回路１が所定位置まで挿入されると、フレキシブル回路１の両端部に設けられた切欠部１ｃに復元しながら嵌合してフレキシブル回路１を前方に係止する係止部５２ａと、係止部５２ａがフレキシブル回路１に嵌合した状態で押圧カバー４０を閉鎖すると、押圧カバー４０に当接して係止部５２ａの下方への移動を規制する規制部５２ｂとを設けたので、フレキシブル回路１がコネクタ本体１０に完全に挿入されたことを挿入操作時の感触によって確認することができ、コネクタ本体１０が未完全挿入状態で接続されることを確実に防止することができる。また、押圧カバー４０を閉鎖したときにはロック端子５０の係止部５２ａをフレキシブル回路１の切欠部１ｃに常に嵌合させることができるので、フレキシブル回路１を前方に係止することができ、フレキシブル回路１がコネクタ本体１０から抜け出したり、位置ずれが生じて接触不良になることを確実に防止することができる。   As described above, according to the connector of this embodiment, the lock terminals 50 are provided at both ends of the connector body 10 in the terminal arrangement direction, and the lock terminals 50 are in contact with the lower surface of the flexible circuit 1 inserted into the connector body 10. When the flexible circuit 1 is elastically deformed and the flexible circuit 1 is inserted to a predetermined position, it is fitted to the notch portions 1c provided at both ends of the flexible circuit 1 while being restored to engage the flexible circuit 1 forward. When the pressing cover 40 is closed in a state in which the locking portion 52a is fitted to the flexible circuit 1, a regulating portion 52b that abuts the pressing cover 40 and regulates the downward movement of the locking portion 52a is provided. Therefore, it can be confirmed by the feel at the time of the insertion operation that the flexible circuit 1 is completely inserted into the connector body 10, and the connector body 10 is not completely inserted. It can be reliably prevented from being connected. Further, when the pressing cover 40 is closed, the locking portion 52a of the lock terminal 50 can always be fitted into the cutout portion 1c of the flexible circuit 1, so that the flexible circuit 1 can be locked forward, and the flexible circuit 1 can be reliably prevented from coming out of the connector main body 10 or causing a positional shift to cause poor contact.

また、係止部５２ａの前端部をコネクタ本体１０の後方に向かって上り傾斜をなすように形成したので、フレキシブル回路１をコネクタ本体１０の後方に案内することができる。従って、フレキシブル回路１をコネクタ本体１０に挿入するときに、フレキシブル回路１の先端が係止部５２ａの前端部に当接することによって挿入が妨げられることがないので、フレキシブル回路１をコネクタ本体１０の後方に容易に挿入することができる。   In addition, since the front end portion of the locking portion 52 a is formed so as to be inclined upward toward the rear of the connector main body 10, the flexible circuit 1 can be guided to the rear of the connector main body 10. Therefore, when the flexible circuit 1 is inserted into the connector main body 10, the insertion of the flexible circuit 1 is not hindered by the front end of the locking portion 52 a coming into contact with the front end of the locking portion 52 a. It can be easily inserted backwards.

さらに、各端子２０，３０を、押圧カバー４０が所定の開放位置まで回動すると、各端子２０，３０の後端側が押圧カバー４０に押圧されることにより各端子２０，３０の前端側が上方に弾性変形するとともに、押圧カバー４０を閉鎖すると各端子２０，３０の前端側が下方に復元してフレキシブル回路１に接触するように形成したので、押圧カバー４０開放時における各端子２０，３０の前端側の間隙Ｄ２を押圧カバー４０閉鎖時の間隙Ｄ１よりも大きく形成することができ、フレキシブル回路１を容易に挿入することができる。   Further, when each of the terminals 20 and 30 is rotated to the predetermined open position, the rear end side of each of the terminals 20 and 30 is pressed against the press cover 40 so that the front end of each of the terminals 20 and 30 is directed upward. Since the front end side of each terminal 20, 30 is restored downward and comes into contact with the flexible circuit 1 when the pressure cover 40 is closed while being elastically deformed, the front end side of each terminal 20, 30 when the pressure cover 40 is opened The gap D2 can be formed larger than the gap D1 when the pressing cover 40 is closed, and the flexible circuit 1 can be easily inserted.

さらにまた、各端子２０，３０を、押圧カバー４０を閉鎖すると弾性片部２１，３１の下面後端側が押圧カバー４０に当接することにより、弾性片部２１，３１の前端側の上方への弾性変形を規制するように形成したので、押圧カバー４０を閉鎖したときに各端子２０，３０の第１の接触部２１ａ，３１ａが各端子２０，３０の弾性変形によってフレキシブル回路１から離間して接触不良になることを確実に防止することができる。   Furthermore, when each of the terminals 20 and 30 is closed, when the pressure cover 40 is closed, the lower rear end side of the elastic piece portions 21 and 31 comes into contact with the pressure cover 40, so that the elasticity of the elastic piece portions 21 and 31 on the front end side is increased upward. Since the deformation is restricted, the first contact portions 21a and 31a of the terminals 20 and 30 are separated from the flexible circuit 1 by the elastic deformation of the terminals 20 and 30 when the pressing cover 40 is closed. It can be surely prevented from becoming defective.

なお、上記実施形態は本発明の一具体例に過ぎず本発明が上記実施形態のみに限定されることはない。例えば、前記実施形態では、各電気接点１ａ，１ｂが設けられた面を上面としてフレキシブル回路１をコネクタ本体１０に挿入する場合について説明したが、各電気接点１ａ，１ｂが設けられた面を下面としてフレキシブル回路１をコネクタ本体１０に挿入してもよい。この場合、各電気接点１ａ，１ｂは、それぞれ第２の端子３０の第２の接触部３２ａと第１の端子２０の第２の接触部２２ａに接触することにより電気的に接続される。また、押圧カバー４０を閉鎖したときには、各端子２０，３０の第１の接触部２１ａ，３１ａはフレキシブル回路１の上面（各電気接点１ａ，１ｂが設けられていない面）に当接するとともに、フレキシブル回路１を各第２の接触部２２ａ，３２ａ側に押圧する。   In addition, the said embodiment is only one specific example of this invention, and this invention is not limited only to the said embodiment. For example, in the above embodiment, the case where the flexible circuit 1 is inserted into the connector body 10 with the surface provided with the electrical contacts 1a and 1b as the upper surface has been described. However, the surface provided with the electrical contacts 1a and 1b is the lower surface. The flexible circuit 1 may be inserted into the connector main body 10. In this case, the electrical contacts 1a and 1b are electrically connected by contacting the second contact portion 32a of the second terminal 30 and the second contact portion 22a of the first terminal 20, respectively. When the pressing cover 40 is closed, the first contact portions 21a and 31a of the terminals 20 and 30 are in contact with the upper surface of the flexible circuit 1 (the surface where the electrical contacts 1a and 1b are not provided) and are flexible. The circuit 1 is pressed toward the second contact portions 22a and 32a.
