Description

シールドコネクタShield connector
　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. Is covered 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.
　シールドコネクタとしては、特許文献１に記載されたものが知られている。この従来例のシールドコネクタは、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、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、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シールドフラットケーブルの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、シールド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 the shield connector, the one described in Patent Document 1 is known. The shield connector of this conventional example includes a housing in which an insertion portion into which a distal end portion where a plurality of conductors of a shielded flat cable are exposed is inserted, a terminal row having a plurality of terminals attached to the insertion portion, and an insertion A conductive shell that covers most of the surface of the housing other than the portion and its surroundings, and a lock portion provided on the conductive shell, on both sides of the tip of the shield flat cable that is inserted into the insertion portion The lock portion is locked to the notch portion provided so that the shield 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.
　また、従来例のシールドコネクタでは、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た折返し片を備え、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シールドフラットケーブルの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、シールドフラットケーブルを挿し込む過程で、シールド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、さらにシールド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シールドフラットケーブルをロックするようにしている。 Further, in the shield connector of the conventional example, the lock portion includes a folded piece obtained by folding a part of the conductive shell member located at both ends in the longitudinal direction of the housing inside the housing, and is tapered at the side edge of the folded piece. The locking portion is formed upright, and the locking portion is formed by being urged in the direction of the notch at the tip of the shield flat cable by the elasticity of the folded piece. As a result, in the process of inserting the shield flat cable, the locking portion that contacts the surface of the shield flat cable is retracted due to bending of the folded piece of the lock portion, and the shield flat cable is further inserted and the notch portion is the locking portion. When the position is reached, the locking portion advances into the cutout portion to lock the shield flat cable.
　一方、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, the lock release unit inserts a columnar member from an opening provided in the conductive shell, abuts the tip on the upper surface of the folded piece of the lock unit, and supports the columnar member on the housing so as to be movable in the vertical direction. Is formed. 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、従来例のシールドコネクタでは、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シールド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, in the shield connector of the conventional example, since the lock portion is covered with the conductive shell, it is determined whether or not the locking portion of the locking portion falls into the notch of the shield flat cable and is securely locked. Difficult to distinguish from the outside. 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、従来例のシールドコネクタでは、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。 Further, in the shield connector of the conventional example, since the unlocking portions are separately provided at both ends in the longitudinal direction of the housing, when releasing the shield flat cable, both unlocking portions must be operated simultaneously. Therefore, it cannot be avoided that the operation becomes complicated.
　本発明が解決しようとする課題は、シールドコネクタの所定位置にシールド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シールド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 shield connector that can visually determine that the shield flat cable is locked at a predetermined position of the shield connector and can be easily unlocked.
　上記課題を解決するため、本発明の態様に係るシールドコネクタは、シールド被覆を備えたシールドフラットケーブル用のものであって、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、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、ハウジングの上面に配置されたシールドロック部材と、端子列の配列方向のハウジングの両端部に固定され、導電性部材で形成され、シールドロック部材をハウジングの上面に押圧する押えばね部を有する押え部材と、シールドロック部材の下面から垂下させて形成され、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一対の係止孔に挿入される先細り状の一対の係止部と、シールドロック部材の長手方向の側縁に設けられ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る。 In order to solve the above problems, a shielded connector according to an aspect of the present invention is for a shielded flat cable having a shield coating, and is a plug-in part into which a plurality of conductors of the shielded flat cable are exposed. A housing having a plurality of terminals mounted on the insertion portion, a shield lock member formed of a conductive member and disposed on the upper surface of the housing, and a housing in the arrangement direction of the terminal rows. A holding member that is fixed to both ends and formed of a conductive member and has a holding spring portion that presses the shield lock member against the upper surface of the housing, and is formed by hanging down from the lower surface of the shield lock member. A pair of tapered locking portions to be inserted into a pair of locking holes formed on both sides, and the length of the shield lock member And a shield contact portion that contacts electrically connected to the shield member is provided shielded flat cable to the side edges of the direction.
　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、係止部を押えばね部でハウジングの上面を押圧していることから、シールドフラットケーブルの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、シールド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シールド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の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シールドフラットケーブルの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の上面の初期位置に戻される。 That is, 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 locking portion is pressed against the upper surface of the housing by the presser spring portion. When the locking hole of the part 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 shield flat cable in the process of inserting the shield flat cable, the shield lock member is pushed upward from 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 shield flat cable and enters the locking hole and is locked, the shield locking member is moved to the initial position on the upper surface of the housing. Return to position.
　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ハウジングの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、ハウジングの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の上面に押し当てられていれば、差込み部の所定位置にシールド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の上面から浮き上がっていれば、半ロックであることを判別できる。この場合、シールド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, 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 shield flat cable is locked at a predetermined position of the insertion portion. Further, if the shield lock member is lifted from the upper surface of the housing, it can be determined that the shield lock member is semi-locked. In this case, it is possible to perform an operation of adjusting the insertion posture of the shield flat cable and locking it in a predetermined position.
　一方、ロックを解除する場合、シールド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で連結されていることから、シールドロック部材を持ち上げることにより、一対の係止部のロックを容易に解除することができる。 On the other hand, when releasing the lock, since the pair of locking portions locked in the locking holes on both sides of the shield flat cable are connected by the shield lock member, by lifting the shield lock member, The pair of locking portions can be easily unlocked.
　また、シールドロック部材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シールドロック部材を覆う必要がないため、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。 Further, since the shield lock member is formed of a conductive member, it is not necessary to cover the shield lock member with another shield member, so that the number of parts can be reduced. Moreover, since the structure of the shield lock member is simple, manufacture and assembly are facilitated.
　シールドコネクタは、導電性部材で形成され、シールドロック部材に隣接してハウジングの上面を覆うためのシールドカバーを備えるてもよい。この場合、シールドカバーは、シールドカバーの長手方向の両端を折り曲げてハウジングの両端に固定される支持部を備える。そして、押え部材が支持部と一体に形成される。また、押え部材は、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の上面に平行に伸延された押えばね部とを備える。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シールドフラットケーブルのシールド部をアースに接続できる。 The shield connector may be formed of a conductive member, and may include a shield cover for covering the upper surface of the housing adjacent to the shield lock member. In this case, the shield cover includes support portions that are fixed to both ends of the housing by bending both ends in the longitudinal direction of the shield cover. The pressing member is formed integrally with the support portion. The presser member includes a grounding portion formed by bending in a horizontal direction from the lower end of the support portion, and a presser spring portion extending in parallel to 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 shield flat cable can be connected to the ground via the shield contact portion of the shield lock member.
　本発明の態様に係るシールドコネクタによれば、シールドコネクタの所定位置にシールド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 shield connector according to the aspect of the present invention, it can be visually determined that the shield flat cable is locked at a predetermined position of the shield connector, and unlocking is facilitated.

However, as shown in FIG. 1, for example, the shield flat cable 20 is formed by sandwiching a plurality of conductor patterns in a flexible insulating film. Is covered with a conductive shield member. The distal end portion 21 of the shield flat cable 20 is formed corresponding to a portion to be inserted into the insertion portion 6 of the shield connector 1. The tip 21 has the shield member removed and a plurality of conductors exposed.
　シールドロック部材４は、差込み部６に装着される端子列３に沿う長手方向を有し、金属などの導電性の板材で形成されている。シールドロック部材４の長手方向の両端には、板材を折り曲げて下面から垂下させた係止部１２と脚部１３が形成されている。係止部１２は、先細り状に形成される。すなわち、係止部１２の差込み部６奥側の面にはシールドロック部材４の下面に対してほぼ鉛直な係止面１２ａが形成され、その反対側の面には傾斜させた進入面１２ｂが形成される。係止部１２は、ハウジング２の上壁２ｂの両端に形成された切り込み１１ｃに挿入されるようになっている。脚部１３は、係止部１２から離して直状の長方形に形成される。脚部１３は、ハウジング２の上壁２ｂの両端に形成された支持孔１１ｂに嵌入されるようになっている。シールドロック部材４のシールドフラットケーブル２０の差込み側の長手方向の縁部には、シールドフラットケーブル２０の上面に接触可能に巻曲げて形成したシールド接触部１４が形成されている。 The shield lock member 4 has a longitudinal direction along the terminal row 3 attached to the insertion portion 6, and is formed of a conductive plate material such as metal. At both ends of the shield lock member 4 in the longitudinal direction, locking portions 12 and leg portions 13 are formed by bending a plate material and hanging from the lower surface. The locking part 12 is formed in a tapered shape. That is, a locking surface 12a substantially perpendicular to the lower surface of the shield lock member 4 is formed on the surface of the locking portion 12 on the back side of the insertion portion 6, and an inclined entry surface 12b is formed on the opposite surface. It is formed. The locking portion 12 is inserted into cuts 11 c formed at both ends of the upper wall 2 b of the housing 2. The leg portion 13 is formed in a rectangular shape that is separated from the locking portion 12. The leg 13 is inserted into support holes 11 b formed at both ends of the upper wall 2 b of the housing 2. A shield contact portion 14 formed by winding the shield lock member 4 so as to be in contact with the upper surface of the shield flat cable 20 is formed at the longitudinal edge of the shield lock member 4 on the insertion side of the shield flat cable 20.
　シールドカバー７は、シールドシェルとも称され、シールドロック部材４に隣接してハウジング２の上壁２ｂを覆って設けられる。シールドカバー７は、シールドロック部材４と共に差込み部６の上面側をシールドする。シールドカバー７は、金属などの導電性の板材で形成され、両端部に折り曲げ形成されたシールドカバー７の支持部７ａと一体に、一対の押え部材５が形成されている。支持部７ａは、ハウジング２の両端に設けられた溝部１１ａに嵌め込まれるようになっている。支持部７ａに連設して形成された押え部材５は、支持部７ａの一部を形成する鉛直部５ｂの下端に折り曲げ形成された水平なアース部５ａと、鉛直部５ｂの上端からハウジング２の上壁２ｂの上面８に平行に伸延された押えばね部５ｃとを備える。 The shield cover 7 is also referred to as a shield shell, and is provided adjacent to the shield lock member 4 so as to cover the upper wall 2b of the housing 2. The shield cover 7 shields the upper surface side of the insertion portion 6 together with the shield lock member 4. The shield cover 7 is formed of a conductive plate material such as metal, and a pair of pressing members 5 are formed integrally with the support portion 7a of the shield cover 7 that is bent at both ends. The support portion 7 a is fitted into groove portions 11 a provided at both ends of the housing 2. The holding member 5 formed continuously with the support portion 7a includes a horizontal grounding portion 5a bent at the lower end of the vertical portion 5b forming a part of the support portion 7a, and the housing 2 from the upper end of the vertical portion 5b. And a presser spring portion 5c extending parallel to the upper surface 8 of the upper wall 2b.
　図２に示すように、ハウジング２の上面８には、図２の手前側から、シールドロック部材４とシールドカバー７とが配置されている。まず、図４（ａ）に示すように、先に、シールドロック部材４の脚部１３をハウジング２の両端に形成された支持孔１１ｂに嵌入しながら、係止部１２を切り込み１１ｃに挿入する。次いで、図４（ｂ）に示すように、シールドロック部材４に並べて図４（ｂ）の奥側にシールドカバー７を位置させて、支持部７ａをハウジング２の両端に形成された溝部１１ａに圧入して固定する。このとき、押え部材５の押えばね部５ｃにより、シールドロック部材４の上面を図４（ｂ）の下方に押圧するように固定する。こうして組み立てたシールドコネクタ１の差込み部６の入口から、シールドフラットケーブル２０の先端部２１を差込み部６の所定位置まで差し入れる。すると、シールドフラットケーブル２０の先端部２１の両側部に形成された矩形の係止孔２３にシールドロック部材４の係止部１２が進入して係止される。こうして、シールドフラットケーブル２０の先端部２１が差込み部６の所定位置にロックされる。そして、先端部２１に露出されている導体（不図示）が、端子列３のそれぞれの端子に接触導通される。 As shown in FIG. 2, a shield lock member 4 and a shield cover 7 are arranged on the upper surface 8 of the housing 2 from the front side of FIG. First, as shown in FIG. 4A, first, the locking portion 12 is inserted into the notch 11c while the legs 13 of the shield lock member 4 are fitted into the support holes 11b formed at both ends of the housing 2. . Next, as shown in FIG. 4 (b), the shield cover 7 is positioned on the back side of FIG. 4 (b) along the shield lock member 4, and the support portions 7 a are formed in the groove portions 11 a formed at both ends of the housing 2. Press fit and fix. At this time, the upper surface of the shield lock member 4 is fixed by the presser spring portion 5c of the presser member 5 so as to press downward in FIG. 4B. The distal end portion 21 of the shield flat cable 20 is inserted into a predetermined position of the insertion portion 6 from the entrance of the insertion portion 6 of the shield connector 1 assembled in this way. Then, the locking portion 12 of the shield lock member 4 enters and is locked into the rectangular locking holes 23 formed on both sides of the tip portion 21 of the shield flat cable 20. Thus, the tip 21 of the shield flat cable 20 is locked at a predetermined position of the insertion portion 6. A conductor (not shown) exposed at the tip 21 is brought into contact with each terminal of the terminal row 3.
　ここで、シールドコネクタ１のロック動作とロック解除動作を、図５（ａ）―５（ｅ）、６（ａ）―６（ｂ）を参照して説明する。図５（ａ）に示すように、シールドフラットケーブル２０の差込み前において、シールドロック部材４は押えばね部５ｃによってハウジング２の底壁２ａに向けて押し付けられている。これにより、係止部１２の先端部がハウジング２の底壁２ａの凹所１１ｄに位置されている。次に、図５（ｂ）に示すように、シールドフラットケーブル２０の先端部２１が矢印３０の方向から差込み部６に差し込まれて先端が係止部１２の進入面１２ｂに達する。そして、シールドフラットケーブル２０をさらに押し込むと、図５（ｃ）に示すように、進入面１２ｂの傾斜面によって係止部１２を押し上げる力が発生し、押えばね部５ｃが上方に変形される。 Here, the locking operation and unlocking operation of the shield connector 1 will be described with reference to FIGS. 5 (a) -5 (e) and 6 (a) -6 (b). As shown in FIG. 5A, before the shield flat cable 20 is inserted, the shield lock member 4 is pressed toward the bottom wall 2a of the housing 2 by the presser spring portion 5c. Thereby, the front-end | tip part of the latching | locking part 12 is located in the recess 11d of the bottom wall 2a of the housing 2. FIG. Next, as shown in FIG. 5B, the distal end portion 21 of the shield flat cable 20 is inserted into the insertion portion 6 from the direction of the arrow 30, and the distal end reaches the entry surface 12 b of the locking portion 12. When the shield flat cable 20 is further pushed in, as shown in FIG. 5C, a force for pushing up the locking portion 12 is generated by the inclined surface of the entry surface 12b, and the presser spring portion 5c is deformed upward.
　シールドフラットケーブル２０をさらに押し込むと、図５（ｄ）に示すように、押えばね部５ｃが上方に変形して、係止部１２が持ち上げられ（図示ｈ）、係止部１２の先端がシールドフラットケーブル２０の先端部２１の上を摺動する。シールドフラットケーブル２０をさらに押し込むと、図５（ｅ）に示すように、係止部１２の先端部がシールドフラットケーブル２０の先端部２１の係止孔２３に進入して、押えばね部５ｃが元に復帰する。この状態のとき、係止部１２の係止面１２ａが係止孔２３の差込み方向の先端側の縁２３ａに当接して係止し、シールドフラットケーブル２０の先端は差込み部６の奥壁の近傍まで差し込まれた状態になる。 When the shield flat cable 20 is further pushed in, as shown in FIG. 5 (d), the presser spring portion 5c is deformed upward, the locking portion 12 is lifted (shown h), and the tip of the locking portion 12 is shielded. It slides on the tip 21 of the flat cable 20. When the shield flat cable 20 is further pushed in, as shown in FIG. 5E, the distal end portion of the locking portion 12 enters the locking hole 23 of the distal end portion 21 of the shield flat cable 20, and the presser spring portion 5c is moved. Return to the original. In this state, the locking surface 12a of the locking portion 12 contacts and locks the edge 23a on the distal end side in the insertion direction of the locking hole 23, and the distal end of the shield flat cable 20 is on the back wall of the insertion portion 6. It will be in the state where it was inserted to the vicinity.
　この状態で、シールドロック部材４のシールド接触部１４が、シールドフラットケーブル２０の表面のシールド部材に導通接触する。これにより、シールドフラットケーブル２０の表面のシールド部材は、シールドロック部材４と押えばね部５ｃとアース部５ａを介して、配線基板（不図示）のアース回路に接続され、所定のシールド効果を発揮することができる。このようにして、シールドフラットケーブル２０の複数の導体が端子列３の複数の端子にそれぞれ導通接触される状態で、位置決めされるとともにロックされる。 In this state, the shield contact portion 14 of the shield lock member 4 is in conductive contact with the shield member on the surface of the shield flat cable 20. As a result, the shield member on the surface of the shield flat cable 20 is connected to the ground circuit of the wiring board (not shown) via the shield lock member 4, the presser spring portion 5c, and the ground portion 5a, and exhibits a predetermined shielding effect. can do. In this manner, the plurality of conductors of the shielded flat cable 20 are positioned and locked in a state of being in conductive contact with the plurality of terminals of the terminal row 3.
　一方、ロック解除は、図６（ａ）に示すように、シールドロック部材４を矢印３１の方向に持ち上げて行う。これにより、係止部１２と係止孔２３の係止が外れて、シールドフラットケーブル２０を矢印３２の方向に引き抜いて、シールドフラットケーブル２０の複数の導体が端子列３の複数の端子にそれぞれ導通接触と、シールドフラットケーブル２０の表面のシールド部材とシールド接触部１４との導通接触が解除される。 On the other hand, unlocking is performed by lifting the shield lock member 4 in the direction of the arrow 31 as shown in FIG. Thereby, the locking of the locking portion 12 and the locking hole 23 is released, the shield flat cable 20 is pulled out in the direction of the arrow 32, and the plurality of conductors of the shield flat cable 20 are respectively connected to the plurality of terminals of the terminal row 3. The conduction contact and the conduction contact between the shield member on the surface of the shield flat cable 20 and the shield contact portion 14 are released.
　実施形態に係るシールドコネクタ１によれば、シールドロック部材４の下面に垂下させて一対の係止部１２を設け、係止部１２を押えばね部５ｃでハウジング２の上面８を押圧している。このため、シールドフラットケーブル２０の先端部２１の係止孔２３が係止部１２の位置に差し込まれると、係止部１２が押えばね部５ｃの弾性によって係止孔２３に挿入されてロックされる。このシールドフラットケーブル２０の差し込み過程で、シールドロック部材４の係止部１２がシールドフラットケーブル２０の表面に当接されている状態のときは、シールドロック部材４はハウジング２の上面８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４の係止部１２がシールドフラットケーブル２０の係止孔２３の位置に達し、係止部１２が係止孔２３に進入してロックがなされると、シールドロック部材４はハウジング２の上面８の初期位置に戻される。したがって、ロック動作の過程では、シールドロック部材４はハウジング２の上面８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４が初期位置に戻る。このため、外部から観察することにより、シールドロック部材４のロック動作の状態を容易に判別できる。言い換えれば、シールドロック部材４がハウジング２の上面８に押し当てられていれば、差込み部６の所定位置にシールドフラットケーブル２０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４がハウジング２の上面８から浮き上がっていれば、半ロックであることを判別でき、シールドフラットケーブル２０の差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。 According to the shield connector 1 according to the embodiment, a pair of locking portions 12 are provided by being suspended from the lower surface of the shield lock member 4, and the locking portion 12 is pressed against the upper surface 8 of the housing 2 by the presser spring portion 5 c. . For this reason, when the locking hole 23 of the distal end portion 21 of the shield flat cable 20 is inserted into the position of the locking portion 12, the locking portion 12 is inserted into the locking hole 23 by the elasticity of the presser spring portion 5c and locked. The In the process of inserting the shield flat cable 20, when the locking portion 12 of the shield lock member 4 is in contact with the surface of the shield flat cable 20, the shield lock member 4 is above the upper surface 8 of the housing 2. Pushed up. When the locking portion 12 of the shield lock member 4 reaches the position of the locking hole 23 of the shield flat cable 20 and the locking portion 12 enters the locking hole 23 and is locked, the shield locking member 4 is The housing 2 is returned to the initial position on the upper surface 8. Therefore, in the process of the locking operation, the shield lock member 4 moves up and down with respect to the upper surface 8 of the housing 2, and when the lock state is reached, the shield lock member 4 returns to the initial position. For this reason, the state of the locking operation of the shield lock member 4 can be easily determined by observing from the outside. In other words, if the shield lock member 4 is pressed against the upper surface 8 of the housing 2, it can be determined that the shield flat cable 20 is locked at a predetermined position of the insertion portion 6. Further, if the shield lock member 4 is lifted from the upper surface 8 of the housing 2, it can be determined that the shield lock member 4 is semi-locked, and an operation of adjusting the differential posture of the shield flat cable 20 to lock it in a predetermined position can be performed. .
　また、ロックを解除する場合は、シールド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、シールドロック部材４を導電性部材で形成したことから、シールドロック部材４を別のシールド部材により覆う必要がない。しかも、シールドロック部材４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 to the locking holes 23 of the shield flat cable are connected by the shield lock member 4. By removing, the lock of the pair of locking portions can be easily released. Moreover, according to this invention, since the shield lock member 4 was formed with the electroconductive member, it is not necessary to cover the shield lock member 4 with another shield member. Moreover, since the structure of the shield lock member 4 is simple, the number of parts can be reduced, and assembly is facilitated.
