Description

本発明は、シールドコネクタに係り、具体的にはシールド被覆を備えたシールドフラットケーブル用のシールドコネクタに関する。   The present invention relates to a shielded connector, and more particularly to a shielded connector for a shielded flat cable having a shield coating.

シールドフラットケーブルは、可撓性を有する絶縁フィルムに複数の導体パターンを挟んで形成されたケーブル、又は、可撓性を有する平板型の導体を複数本並べて被覆したリボン状のケーブルなどのフラットケーブル（平型ケーブル）を、導電性のシールド部材で被覆して形成されている。このようなシールドフラットケーブルを配線基板等の電子部品に接続するために、通常、シールドコネクタが用いられる。   The shielded flat cable is a cable formed by sandwiching a plurality of conductor patterns on a flexible insulating film, or a flat cable such as a ribbon-shaped cable in which a plurality of flexible flat conductors are lined up and covered. (Flat cable) is formed by covering with a conductive shield member. In order to connect such a shielded flat cable to an electronic component such as a wiring board, a shield connector is usually used.

シールドコネクタ（以下、単にコネクタと略称する。）としては、例えば、特許文献１に記載されたものが知られている。これによれば、シールドフラットケーブル（以下、単にフラットケーブルと略称する。）の複数の導体が露出された先端部が差し込まれる差込み部が形成されたハウジングと、差込み部に装着された複数の端子を備えた端子列と、差込み部及びその周囲部分を除く他の部分のハウジング表面の大部分を覆う導電性シェルと、その導電性シェルに設けられたロック部とを備え、差込み部に差し込まれるフラットケーブル先端部の両側に設けられた切欠き部にロック部を係止させて、フラットケーブルをシールドコネクタに係止すると共に、位置決めするようにしている。また、導電性シェルを配線基板に設けられた接地端子に接続するようにしている。   As a shield connector (hereinafter simply referred to as a connector), for example, the one described in Patent Document 1 is known. According to this, the housing in which the insertion part into which the front-end | tip part in which the some conductor of the shield flat cable (henceforth a flat cable) was exposed was formed was formed, and the several terminal with which the insertion part was mounted | worn And a conductive shell that covers most of the housing surface of the other portion excluding the insertion portion and the surrounding portion, and a lock portion provided on the conductive shell, and is inserted into the insertion portion. The lock portion is locked to the notches provided on both sides of the flat cable tip, and the flat cable is locked to the shield connector and positioned. Further, the conductive shell is connected to a ground terminal provided on the wiring board.

特許文献１に記載のロック部は、ハウジングの長手方向の両端部に位置する導電性シェルの部材の一部をハウジング内部に折り返し、その折り返し片の側縁に先細り状の係止部を起立させて形成し、その係止部を折り返し片の弾性によりフラットケーブル先端部の切欠き部の方向に付勢して形成されている。これにより、フラットケーブルを挿し込む過程で、フラットケーブルの表面に当接した係止部がロック部の折り返し片の撓みによって後退し、さらにフラットケーブルを差し込んで切欠き部が係止部の位置に達したときに、係止部が切欠き部に進出してフラットケーブルをロックするようにしている。   In the lock portion described in Patent Document 1, a part of the member of the conductive shell located at both ends in the longitudinal direction of the housing is folded inside the housing, and a tapered locking portion is erected on the side edge of the folded piece. The locking portion is formed by urging the locking portion in the direction of the notch at the tip of the flat cable by the elasticity of the folded piece. As a result, in the process of inserting the flat cable, the latching portion that contacts the surface of the flat cable is retracted due to the bending of the folded piece of the lock portion, and the flat cable is further inserted and the notch is brought to the position of the latching portion. When it reaches, the locking part advances into the notch and locks the flat cable.

一方、特許文献１に記載されたロック解除部は、柱状部材を導電性シェルに設けた開口から挿入して、先端をロック部の折り返し片の上面に当接させ、柱状部材を上下方向に移動可能にハウジングに支持させて形成されている。そして、導電性シェルの開口から突き出たロック解除部を下方に変位させてロック部の折り返し片を撓ませることにより、係止部を切欠き部から退出させてロックを解除するように形成されている。   On the other hand, in the lock release part described in Patent Document 1, the columnar member is inserted from the opening provided in the conductive shell, the tip is brought into contact with the upper surface of the folded piece of the lock part, and the columnar member is moved in the vertical direction. It is formed so as to be supported by the housing. Then, the lock release portion protruding from the opening of the conductive shell is displaced downward to bend the folded piece of the lock portion, so that the locking portion is retreated from the cutout portion to release the lock. Yes.

しかしながら、特許文献１のロック部は、導電性シェルで覆われているから、ロック部の係止部がフラットケーブルの切欠きに落ち込んで、確実に係止されているか否かを外部から見て判別しにくい。この点、導電性シェルの開口からのロック解除部の突出し量によってロック状態をある程度判別できるが、例えば、何らかの原因で確実にロックされていない半ロックの状態になっていると、導通不良等が起きやすいという問題がある。   However, since the lock part of patent document 1 is covered with the conductive shell, it is seen from the outside whether the locking part of the locking part falls into the notch of the flat cable and is securely locked. Difficult to distinguish. In this regard, the locked state can be determined to some extent by the protruding amount of the unlocking portion from the opening of the conductive shell, but for example, if it is in a semi-locked state that is not securely locked for some reason, a continuity failure etc. There is a problem that it is easy to get up.

また、特許文献１のロック解除部は、ハウジングの長手方向の両端部に別々に設けられているから、シールドフラットケーブルを離脱するとき、両方のロック解除部を同時に操作しなければならないので、操作が煩雑になるのを避けることができない。   Moreover, since the unlocking part of patent document 1 is separately provided in the both ends of the longitudinal direction of a housing, when removing a shield flat cable, since both unlocking parts must be operated simultaneously, operation Can not be avoided.

本発明が解決しようとする課題は、コネクタの所定位置にフラットケーブルがロックされていることを外観で判別でき、かつロックの解除が容易なコネクタを提供することにある。   The problem to be solved by the present invention is to provide a connector that can visually determine that a flat cable is locked at a predetermined position of the connector and can be easily unlocked.

上記課題を解決するため、本発明のシールドフラットケーブル用コネクタは、シールドフラットケーブルの複数の導体が露出された先端部が差し込まれる差込み部が形成されたハウジングと、前記差込み部に装着された複数の端子を備えた端子列と、導電性部材で形成され、前記差込み部のハウジング上面に配置されたシールドロック部材と、前記端子列の配列方向の前記ハウジングの両端部に固定され、導電性部材で形成され、前記シールドロック部材を前記差込み部のハウジング上面に押圧する押えばね部を有する押え部材と、前記シールドロック部材の下面から垂下させて形成され、前記シールドフラットケーブルの先端部の両側に形成された係止孔にそれぞれ挿入される先細り状の一対の係止部と、前記シールドロック部材の長手方向の側縁に設けられ前記シールドフラットケーブルのシールド部材に接触導通されるシールド接触部とを備えていることを特徴とする。   In order to solve the above-mentioned problems, a shielded flat cable connector according to the present invention includes a housing in which an insertion part into which a distal end part where a plurality of conductors of a shielded flat cable are exposed is formed, and a plurality of parts attached to the insertion part. A terminal row provided with a plurality of terminals, a shield lock member formed on the upper surface of the housing of the insertion portion, and a conductive member fixed to both ends of the housing in the arrangement direction of the terminal row. And a presser member having a presser spring portion that presses the shield lock member against the upper surface of the housing of the insertion portion, and is formed by hanging from the lower surface of the shield lock member, on both sides of the tip of the shield flat cable. A pair of tapered locking portions that are respectively inserted into the formed locking holes, and the longitudinal direction of the shield lock member Characterized in that it includes a shield contact portion provided on the side edge is in contact electrically connected to the shield member of the shielded flat cable.

すなわち、導電性部材で形成されたシールドロック部材の下面に垂下させて一対の係止部を設け、この係止部を押えばね部で差込み部のハウジング上面を押圧していることから、フラットケーブル先端部の係止孔が係止部の位置に差し込まれると、係止部が押えばね部の弾性によって係止孔に挿入されてロックされる。このとき、フラットケーブルの差し込み過程で、シールドロック部材の係止部がフラットケーブルの表面に当接された状態のときは、シールドロック部材はハウジング上面よりも上方に押し上げられる。そして、シールドロック部材の係止部がフラットケーブル先端部に形成された係止孔の位置に達して係止孔に進入してロックがなされると、シールドロック部材はハウジング上面の初期位置に戻される。   In other words, a flat cable is provided because a pair of locking portions are provided by being suspended from the lower surface of the shield lock member formed of a conductive member, and the upper surface of the housing of the insertion portion is pressed by the pressing spring portion. When the locking hole at the distal end is inserted into the position of the locking part, the locking part is inserted into the locking hole and locked by the elasticity of the presser spring part. At this time, when the locking portion of the shield lock member is in contact with the surface of the flat cable in the process of inserting the flat cable, the shield lock member is pushed up above the upper surface of the housing. When the locking portion of the shield lock member reaches the position of the locking hole formed at the tip of the flat cable and enters the locking hole and is locked, the shield locking member is returned to the initial position on the upper surface of the housing. It is.

したがって、ロック動作の過程では、シールドロック部材は差込み部のハウジング上面に対して上下動し、ロック状態に至ったときはシールドロック部材が初期位置に戻る。このように、シールドロック部材は、ハウジング上面に位置されているから、外部から観察することにより、シールドロック部材のロック動作の状態を容易に判別できる。つまり、シールドロック部材がハウジング上面に押し当てられていれば、差込み部の所定位置にフラットケーブルがロックされていることを判別できる。また、シールドロック部材がハウジング上面から浮き上がっていれば、半ロックないし半係止状態であることを判別できる。この場合、フラットケーブルの差込み姿勢を調節して所定位置にロックさせる操作を行うことができる。   Therefore, in the lock operation process, the shield lock member moves up and down with respect to the upper surface of the housing of the insertion portion, and when the lock state is reached, the shield lock member returns to the initial position. Thus, since the shield lock member is located on the upper surface of the housing, the state of the lock operation of the shield lock member can be easily determined by observing from the outside. That is, if the shield lock member is pressed against the upper surface of the housing, it can be determined that the flat cable is locked at a predetermined position of the insertion portion. If the shield lock member is lifted from the upper surface of the housing, it can be determined that the shield lock member is in a half-locked or half-locked state. In this case, it is possible to perform an operation of adjusting the insertion posture of the flat cable and locking it at a predetermined position.

一方、本実施形態においてロックを解除する場合、フラットケーブルの両側部の係止孔に係止している一対の係止部は、シールドロック部材４で連結されていることから、シールドロック部材４を持ち上げることにより、一対の係止部１２のロックを容易に解除することができる。   On the other hand, when the lock is released in the present embodiment, the pair of locking portions locked in the locking holes on both sides of the flat cable are connected by the shield lock member 4. By lifting up, the lock of the pair of locking portions 12 can be easily released.

また、本実施形態によれば、シールドロック部材４が導電性部材で形成されているから、別のシールド部材によりロック部材を覆う必要がないから、部品点数を減らすことができる。しかも、シールドロック部材４の構造が簡単であるから、製造及び組み付けが容易になる。   Moreover, according to this embodiment, since the shield lock member 4 is formed of a conductive member, it is not necessary to cover the lock member with another shield member, so that the number of parts can be reduced. In addition, since the structure of the shield lock member 4 is simple, manufacture and assembly are facilitated.

この場合において、さらに、前記シールドロック部材に隣接して前記ハウジングの上面を覆って導電性部材で形成されたシールドカバーを備えることができる。そして、前記押え部材を、前記シールドカバーの長手方向の両端を折り曲げて前記ハウジングの両端に固定される支持部と一体に形成し、支持部の下端から水平方向に折り曲げて形成されたアース部と、支持部の上端からハウジング上面に平行に伸延された押えばね部とを有して形成することができる。このように形成することにより、シールドカバーとシールドロック部材を電気的に接続することができ、部品点数を減らすことができる。また、アース部を外部の接地回路に接続すれば、シールドロック部材のシールド接触部を介してフラットケーブルのシールド部をアースに接続できる。   In this case, a shield cover formed of a conductive member may be provided so as to cover the upper surface of the housing adjacent to the shield lock member. And, the holding member is formed integrally with a support part that is fixed to both ends of the housing by bending both ends in the longitudinal direction of the shield cover, and a ground part that is formed by bending horizontally from the lower end of the support part; And a presser spring portion extending in parallel with the upper surface of the housing from the upper end of the support portion. By forming in this way, the shield cover and the shield lock member can be electrically connected, and the number of parts can be reduced. Further, if the ground portion is connected to an external ground circuit, the shield portion of the flat cable can be connected to the ground via the shield contact portion of the shield lock member.

本発明によれば、コネクタの所定位置にフラットケーブルがロックされていることを外観で判別でき、かつロックの解除が容易になる。   According to the present invention, it can be determined by appearance that the flat cable is locked at a predetermined position of the connector, and unlocking is facilitated.

In the process of inserting the flat cable 20, when the locking portion 12 of the shield lock member 4 is in contact with the surface of the flat cable 20, the shield lock member 4 is pushed up above the housing upper surface 8. When the locking portion 12 of the shield lock member 4 reaches the position of the locking hole 23 of the flat cable and the locking portion 12 enters the locking hole 23 and is locked, the shield locking member 4 is moved to the upper surface of the housing. 8 is returned to the initial position. Therefore, in the lock operation process, the shield lock member 4 moves up and down with respect to the housing upper surface 8 of the insertion portion 6, and when the lock state is reached, the shield lock member 4 returns to the initial position. Thus, the state of the lock operation of the shield lock member 4 can be easily determined. In other words, if the shield lock member 4 is pressed against the housing upper surface 8, it can be determined that the flat cable 20 is locked at a predetermined position of the insertion portion 6. If the shield lock member 4 is lifted from the upper surface 8 of the housing, it can be determined that the shield lock member 4 is in a half-locked or half-locked state, and an operation of adjusting the insertion posture of the flat cable 20 to lock it in a predetermined position can be performed. it can.

また、ロックを解除する場合は、フラットケーブルの係止孔２３に係止する一対の係止部１２は、シールドロック部材４で連結されているから、押え部材５を外してシールドロック部材を取り外すことにより、一対の係止部のロックを容易に解除することができる。また、本発明によれば、ロック部材を導電性部材で形成したことから、別のシールド部材によりロック部材を覆う必要がない。しかも、ロック部材の構造が簡単であるから、部品点数を減らすことができ、組み付けが容易になる。   When releasing the lock, the pair of locking portions 12 locked in the locking holes 23 of the flat cable are connected by the shield lock member 4, so that the presser member 5 is removed and the shield lock member is removed. Thus, the pair of locking portions can be easily unlocked. Moreover, according to this invention, since the lock member was formed with the electroconductive member, it is not necessary to cover a lock member with another shield member. Moreover, since the structure of the lock member is simple, the number of parts can be reduced, and assembly is facilitated.

また、本実施形態によれば、シールドカバー７と一体に押え部材５を形成しているから、シールドロック部材４とシールドカバー７とを容易に電気的に接続でき、押え部材５のアース部５ａを配線基板等のアース回路に接続するだけで、コネクタ１のシールドを行うことができる。しかも、シールドロック部材４のシールド接触部１４を介して、フラットケーブル２０のシールド部材を容易に配線基板等のアース回路に接続することができる。   In addition, according to the present embodiment, since the pressing member 5 is formed integrally with the shield cover 7, the shield lock member 4 and the shield cover 7 can be easily electrically connected, and the ground portion 5 a of the pressing member 5 can be obtained. The connector 1 can be shielded simply by connecting to a ground circuit such as a wiring board. In addition, the shield member of the flat cable 20 can be easily connected to an earth circuit such as a wiring board via the shield contact portion 14 of the shield lock member 4.
