Abstract

<P>PROBLEM TO BE SOLVED: To provide a connector capable of implementing impedance matching and EMI countermeasures. <P>SOLUTION: Since this connector is provided with a second shield member 50 facing a first shield member 40 by interposing respective terminals 20 therebetween, and detachably formed in a connector body 10, EMI countermeasures can be implemented because the rear surface side of a flexible circuit 1 is covered with the second shield member 50 when the second shield member 50 is mounted to the connector body 10; and when the second shield member 50 is detached from the connector body 10, impedance matching can be implemented because capacitance is not generated between the respective terminals 20 and the second shield member 50. Accordingly, since the impedance matching and the EMI countermeasures can be implemented by the single connector, the need of separately manufacturing connectors having structures corresponding to respective functions is obviated, and the manufacturing cost of the connector can be reduced. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、例えばフレキシブルプリント回路（ＦＰＣ）やフレキシブルフラットケーブル（ＦＦＣ）等を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 connecting, for example, a flexible printed circuit (FPC) or a flexible flat cable (FFC).

従来、この種のコネクタとして、接続対象物を所定位置に挿入可能なコネクタ本体と、接続対象物の一方の面に接触する複数の端子と、接続対象物の他方の面に接触するシールド部材とを備え、接続対象物がコネクタ本体に挿入されると、シールド部材及び各端子が接続対象物に接触するようにしたものが知られている。   Conventionally, as this type of connector, a connector main body in which a connection object can be inserted at a predetermined position, a plurality of terminals that contact one surface of the connection object, and a shield member that contacts the other surface of the connection object When the connection object is inserted into the connector body, the shield member and each terminal are in contact with the connection object.

しかしながら、このコネクタでは、接続対象物の一方の面側がシールド部材で覆われていないため、ＥＭＩ（Ｅｌｅｃｔｒｏ Ｍａｇｎｅｔｉｃ Ｉｎｔｅｒｆｅｒｅｎｃｅ：電磁波障害）対策が十分でない。   However, in this connector, since one surface side of the connection object is not covered with the shield member, an EMI (Electro Magnetic Interference) countermeasure is not sufficient.

そこで、各端子を間にして前記シールド部材と対向する他のシールド部材を設けたものが知られている（例えば特許文献１参照）。
特開２００１−１１０４９３号公報 In view of this, there is known one provided with another shield member facing the shield member with each terminal interposed therebetween (see, for example, Patent Document 1).
JP 2001-110493 A

しかしながら、このコネクタでは、他のシールド部材と各端子との間に生じるキャパシタンスの影響によりコネクタのインピーダンスが変動するため、他のシールド部材を設けない場合と比較してインピーダンスマッチングを適切に行うことができない。従って、インピーダンスマッチング及びＥＭＩ対策を適切に行うためには、それぞれの機能に対応した構造を有するコネクタを別々に製造する必要があり、コネクタの製造コストが嵩むという問題点があった。   However, in this connector, since the impedance of the connector fluctuates due to the influence of the capacitance generated between the other shield member and each terminal, impedance matching can be appropriately performed as compared with the case where no other shield member is provided. Can not. Therefore, in order to appropriately perform impedance matching and EMI countermeasures, it is necessary to separately manufacture connectors having a structure corresponding to each function, and there is a problem that the manufacturing cost of the connector increases.

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、インピーダンスマッチング及びＥＭＩ対策の何れも行うことの可能な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 an object thereof is to provide a connector capable of performing both impedance matching and EMI countermeasures.

本発明は、前記目的を達成するために、接続対象物を所定位置に挿入可能なコネクタ本体と、接続対象物の一方の面に接触する複数の端子と、接続対象物の他方の面に接触する第１のシールド部材とを備え、接続対象物がコネクタ本体に挿入されると、第１のシールド部材及び各端子が接続対象物に接触するようにしたコネクタにおいて、前記各端子を間にして第１のシールド部材と対向するとともに、コネクタ本体に着脱可能に形成された第２のシールド部材を備えている。   In order to achieve the above object, the present invention provides a connector main body in which a connection object can be inserted at a predetermined position, a plurality of terminals that contact one surface of the connection object, and a contact with the other surface of the connection object. A first shield member, and when the connection object is inserted into the connector body, the first shield member and each terminal are in contact with the connection object. The second shield member is provided so as to face the first shield member and to be detachable from the connector main body.

これにより、第２のシールド部材をコネクタ本体に装着した場合には、接続対象物の一方の面側が第２のシールド部材で覆われることからＥＭＩ対策を行うことが可能となり、第２のシールド部材をコネクタ本体から取り外した場合には、各端子と第２のシールド部材との間にキャパシタンスが生じないことからインピーダンスマッチングを行うことが可能となる。   As a result, when the second shield member is attached to the connector body, one surface side of the connection object is covered with the second shield member, so that it is possible to take measures against EMI, and the second shield member When the connector is removed from the connector body, no impedance is generated between each terminal and the second shield member, so that impedance matching can be performed.

本発明によれば、１つのコネクタでインピーダンスマッチング及びＥＭＩ対策の何れも行うことができるので、それぞれの機能に対応した構造を有するコネクタを別々に製造する必要がなくなり、コネクタの製造コストを低減させることができる。これにより、用途に応じてインピーダンスマッチングやＥＭＩ対策を必要とする狭ピッチコネクタとして用いる場合には特に好適である。   According to the present invention, since it is possible to perform both impedance matching and EMI countermeasures with a single connector, it is not necessary to separately manufacture connectors having a structure corresponding to each function, thereby reducing the manufacturing cost of the connector. be able to. This is particularly suitable for use as a narrow pitch connector that requires impedance matching and EMI countermeasures depending on the application.

Are provided at equal intervals. A groove 10c into which the first shield member 40 is press-fitted is provided between the front surface side and the back surface side of the terminal hole 10b, and the groove 10c is opened upward of the connector body 10. Further, the back surface portion 12 is provided with a protruding portion 12a formed so as to extend rearward.

各端子２０は導電性の金属板からなり、コネクタ本体１０の各端子孔１０ｂにそれぞれ底面側から圧入することによって保持されている。各端子２０の一端側には互いに前後方向に間隔をおいて上方に二股状に延びる固定片部２１及び弾性片部２２が設けられるとともに、弾性片部２２はフレキシブル回路１の一方の面側（背面側）に位置するように設けられ、固定片部２１は第１のシールド部材４０を間にして弾性片部２２と対向するように設けられている。固定片部２１はコネクタ本体１０の前面部１１に沿って上下方向に延び、その先端側は端子孔１０ｂから上方に突出している。また、固定片部２１の先端側には開閉部材３０を係止する係止部２１ａが後方に向かって突設されている。弾性片部２２はコネクタ本体１０の前後方向に弾性変形可能に形成され、その先端側にはフレキシブル回路１の電気接点に接触する接触部２２ａが前方に向かって突設されている。各端子２０の他端側はコネクタ本体１０の底面部１４に沿って前後方向に延びるとともに、コネクタ本体１０の背面側から外部に露出している。また、各端子２０の他端側には基板１００に接続される接続部２３が設けられ、接続部２３は端子２０の下端から後方に延びるように形成されている。   Each terminal 20 is made of a conductive metal plate, and is held by being press-fitted into each terminal hole 10b of the connector body 10 from the bottom surface side. A fixed piece portion 21 and an elastic piece portion 22 are provided on one end side of each terminal 20 so as to be bifurcated upwardly with an interval in the front-rear direction, and the elastic piece portion 22 is provided on one surface side of the flexible circuit 1 ( The fixed piece portion 21 is provided so as to face the elastic piece portion 22 with the first shield member 40 in between. The fixed piece portion 21 extends in the vertical direction along the front surface portion 11 of the connector body 10, and the tip end side thereof protrudes upward from the terminal hole 10 b. In addition, a locking portion 21 a that locks the opening / closing member 30 protrudes rearward from the distal end side of the fixed piece portion 21. The elastic piece portion 22 is formed so as to be elastically deformable in the front-rear direction of the connector main body 10, and a contact portion 22 a that contacts an electric contact of the flexible circuit 1 protrudes forward from the distal end side thereof. The other end side of each terminal 20 extends in the front-rear direction along the bottom surface portion 14 of the connector body 10 and is exposed to the outside from the back side of the connector body 10. Further, a connection portion 23 connected to the substrate 100 is provided on the other end side of each terminal 20, and the connection portion 23 is formed to extend rearward from the lower end of the terminal 20.

開閉部材３０は合成樹脂の成形品からなり、コネクタ本体１０の上面側及び前面側を覆うように略Ｌ字状に形成されている。開閉部材３０の前端側には各端子２０の固定片部２１を挿通する複数の端子挿通孔３０ａが互いに幅方向に等間隔で設けられ、各端子挿通孔３０ａの一端側には第１のシールド部材４０を後方へ押圧する押圧部３１が設けられている。押圧部３１は端子２０の固定片部２１と第１のシールド部材４０との間に配置され、固定片部２１の係止部２１ａと前面部１１の上端に係止することにより、上下方向への移動が規制されている。この場合、押圧部３１は、開閉部材３０が開放位置（開閉部材３０の上面が水平方向と平行をなす位置）にあるときの前後方向の寸法が固定片部２１と第１のシールド部材４０との間隔よりも小さく、開閉部材３０が閉鎖位置（開閉部材３０の上面が水平方向と略３０°をなす位置）にあるときの前後方向の寸法が固定片部２１と第１のシールド部材４０との間隔よりも大きくなるように断面が一方向に長く形成されている。   The opening / closing member 30 is made of a synthetic resin molded product, and is formed in a substantially L shape so as to cover the upper surface side and the front surface side of the connector body 10. A plurality of terminal insertion holes 30a through which the fixed piece portions 21 of the respective terminals 20 are inserted are provided at equal intervals in the width direction on the front end side of the opening / closing member 30, and a first shield is provided on one end side of each terminal insertion hole 30a. A pressing portion 31 that presses the member 40 backward is provided. The pressing portion 31 is disposed between the fixed piece portion 21 of the terminal 20 and the first shield member 40, and is locked in the vertical direction by being locked to the locking portion 21 a of the fixed piece portion 21 and the upper end of the front surface portion 11. Movement is regulated. In this case, the pressing portion 31 has a dimension in the front-rear direction when the opening / closing member 30 is in the open position (a position in which the upper surface of the opening / closing member 30 is parallel to the horizontal direction) and the fixed piece portion 21 and the first shield member 40. The dimension in the front-rear direction when the opening / closing member 30 is in the closed position (a position where the upper surface of the opening / closing member 30 forms approximately 30 ° with the horizontal direction) is smaller than the distance between the fixed piece portion 21 and the first shield member 40. The cross section is formed long in one direction so as to be larger than the interval.

第１のシールド部材４０はコネクタ本体１０の幅方向に延びる導電性の金属板からなり、その下端側をコネクタ本体１０の溝１０ｃに上方から圧入することにより、コネクタ本体１０に前後方向に弾性変形可能に取付けられている。この場合、第１のシールド部材４０はフレキシブル回路１の一方の面側（前面側）に位置するようになっており、第１のシールド部材４０の幅方向中央部には、開閉部材３０の各押圧部３１に押圧されると後方に弾性変形してフレキシブル回路１のグランド部に接触する接触片４１が設けられている。また、第１のシールド部材４０の幅方向両端側はコネクタ本体１０の側面部１３の前端側を覆うように略Ｌ字状に形成され、その下端側には基板１００に接続されるグランド用接続部４２が設けられている。   The first shield member 40 is made of a conductive metal plate extending in the width direction of the connector body 10, and its lower end side is press-fitted into the groove 10 c of the connector body 10 from above, thereby elastically deforming the connector body 10 in the front-rear direction. Installed as possible. In this case, the first shield member 40 is located on one surface side (front surface side) of the flexible circuit 1, and each of the opening / closing members 30 is disposed at the center in the width direction of the first shield member 40. A contact piece 41 is provided that is elastically deformed backward when pressed by the pressing portion 31 and contacts the ground portion of the flexible circuit 1. Further, both end sides in the width direction of the first shield member 40 are formed in a substantially L shape so as to cover the front end side of the side surface portion 13 of the connector main body 10, and a ground connection connected to the substrate 100 at the lower end side thereof. A portion 42 is provided.

第２のシールド部材５０はコネクタ本体１０の幅方向に延びる導電性の金属板を略コ字状に折り曲げ形成したものからなり、コネクタ本体１０の背面部１２に上下方向に着脱可能に形成されている。また、第２のシールド部材５０には、背面部１２の前面の幅方向両端側を覆うように形成された接触部５１と、コネクタ本体１０の後方に向かって開口するように形成された嵌合部５２とが設けられており、第２のシールド部材５０をコネクタ本体１０の背面部１２に取り付けると、接触部５１が第１のシールド部材４０に接触し、コネクタ本体１０の突出部１２ａが嵌合部５２に嵌合するようになっている。   The second shield member 50 is formed by bending a conductive metal plate extending in the width direction of the connector main body 10 into a substantially U shape, and is formed on the back surface portion 12 of the connector main body 10 so as to be detachable in the vertical direction. Yes. The second shield member 50 has a contact portion 51 formed so as to cover both ends of the front surface of the back surface portion 12 in the width direction, and a fitting formed so as to open toward the rear of the connector body 10. When the second shield member 50 is attached to the back surface portion 12 of the connector main body 10, the contact portion 51 contacts the first shield member 40 and the protruding portion 12 a of the connector main body 10 is fitted. It fits into the joint 52.

以上のように構成されたコネクタは、図４に示すように開閉部材３０を開放位置にした状態で組み立てられる。また、コネクタを基板１００に実装する際は、開閉部材３０を開放位置にしたまま各端子２０の接続部２３及び第１のシールド部材４０の接続部４２が半田付けにより基板１００に接続される。   The connector configured as described above is assembled with the opening / closing member 30 in the open position as shown in FIG. Further, when the connector is mounted on the substrate 100, the connection portion 23 of each terminal 20 and the connection portion 42 of the first shield member 40 are connected to the substrate 100 by soldering with the opening / closing member 30 in the open position.

ここで、コネクタをＥＭＩ対策用として適用する場合には、コネクタを基板１００に実装した後、フレキシブル回路１の一端側を開口部１０ａ内に挿入し、図５に示すように開閉部材３０を閉鎖位置まで回動すると、押圧部３１が端子２０の固定片部２１に当接しながら開閉部材３０と一体に回動し、押圧部３１によって第１のシールド部材４０の接触片４１が後方に押圧される。これにより、接触片４１が後方に弾性変形してフレキシブル回路１の前方の面（グランド）側に圧接するとともに、フレキシブル回路１の後方の面（信号線）側が可動片部２２に圧接し、フレキシブル回路１が接続される。この場合、開閉部材３０の回動部分の下方に位置するフレキシブル回路１が第１のシールド部材４０によって覆われることから、開閉部材３０の回動部分において外部からの電磁波が遮断される。また、フレキシブル回路１の後方の面側は第２のシールド部材５０によって覆われることから、外部からの電磁波が遮断される。   Here, when the connector is applied as an EMI countermeasure, after the connector is mounted on the substrate 100, one end of the flexible circuit 1 is inserted into the opening 10a, and the opening / closing member 30 is closed as shown in FIG. When rotating to the position, the pressing portion 31 rotates integrally with the opening / closing member 30 while abutting against the fixed piece portion 21 of the terminal 20, and the contact piece 41 of the first shield member 40 is pressed backward by the pressing portion 31. The As a result, the contact piece 41 is elastically deformed rearward and pressed against the front surface (ground) side of the flexible circuit 1, and the rear surface (signal line) side of the flexible circuit 1 is pressed against the movable piece portion 22 and is flexible. Circuit 1 is connected. In this case, since the flexible circuit 1 positioned below the rotating portion of the opening / closing member 30 is covered with the first shield member 40, electromagnetic waves from the outside are blocked at the rotating portion of the opening / closing member 30. Further, since the rear surface side of the flexible circuit 1 is covered with the second shield member 50, electromagnetic waves from the outside are blocked.

また、コネクタをインピーダンスマッチング用として適用する場合には、第２のシールド部材５０の嵌合部５２とコネクタ本体１０の突出部１２ａとの嵌合を解除して第２のシールド部材５０をコネクタ本体１０から取り外した状態において、上記のようにフレキシブル回路１をコネクタ本体１０に挿入して各端子２０に接続させる。この場合、フレキシブル回路１の後方の面側は第２のシールド部材５０によって覆われていないことから、各端子２０と第２のシールド部材５０との間にキャパシタンスが生じない。   When the connector is used for impedance matching, the fitting between the fitting portion 52 of the second shield member 50 and the protruding portion 12a of the connector main body 10 is released, and the second shield member 50 is used as the connector main body. In a state of being removed from 10, the flexible circuit 1 is inserted into the connector main body 10 and connected to each terminal 20 as described above. In this case, since the rear surface side of the flexible circuit 1 is not covered with the second shield member 50, no capacitance is generated between each terminal 20 and the second shield member 50.

このように、本実施形態のコネクタによれば、各端子２０を間にして第１のシールド部材４０と対向するとともに、コネクタ本体１０に着脱可能に形成された第２のシールド部材５０を備えたので、第２のシールド部材５０をコネクタ本体１０に装着した場合には、フレキシブル回路１の後方の面側が第２のシールド部材５０で覆われることからＥＭＩ対策を行うことが可能となり、第２のシールド部材５０をコネクタ本体１０から取り外した場合には、各端子２０と第２のシールド部材５０との間にキャパシタンスが生じないことからインピーダンスマッチングを行うことが可能となる。従って、１つのコネクタでインピーダンスマッチング及びＥＭＩ対策を行うことができるので、それぞれの機能に対応した構造を有するコネクタを別々に製造する必要がなく、コネクタの製造コストを低減させることができる。これにより、用途に応じてインピーダンスマッチングやＥＭＩ対策を必要とする狭ピッチコネクタとして用いる場合には特に好適である。   As described above, according to the connector of the present embodiment, the second shield member 50 is provided which is opposed to the first shield member 40 with the terminals 20 interposed therebetween and is detachably formed on the connector main body 10. Therefore, when the second shield member 50 is attached to the connector main body 10, the rear surface side of the flexible circuit 1 is covered with the second shield member 50, so that it is possible to take EMI countermeasures. When the shield member 50 is removed from the connector main body 10, impedance matching can be performed because no capacitance is generated between each terminal 20 and the second shield member 50. Therefore, since impedance matching and EMI countermeasures can be performed with one connector, it is not necessary to separately manufacture connectors having a structure corresponding to each function, and the manufacturing cost of the connector can be reduced. This is particularly suitable for use as a narrow pitch connector that requires impedance matching and EMI countermeasures depending on the application.

また、第１のシールド部材４０に外部のグランド部に接続可能なグランド用接続部４２を設けるとともに、第２のシールド部材５０に、第２のシールド部材５０をコネクタ本体１０に取り付けると、第１のシールド部材４０に接触する接触部５１を設けたので、第１及び第２のシールド部材４０，５０を電磁波遮断用の部材のみならず、グランド接続用の部材としても用いることができ、部品点数を少なくすることができる。   In addition, the first shield member 40 is provided with a ground connection portion 42 that can be connected to an external ground portion, and when the second shield member 50 is attached to the connector body 10 to the second shield member 50, Since the contact portion 51 that contacts the shield member 40 is provided, the first and second shield members 40 and 50 can be used not only as an electromagnetic wave shielding member but also as a ground connection member. Can be reduced.

さらに、コネクタ本体１０に、第２のシールド部材５０をコネクタ本体１０に取り付けると、第２のシールド部材５０に設けられた嵌合部５２に嵌合する突出部１２ａを設けたので、第２のシールド部材５０をコネクタ本体１０に取り付けた場合には第２のシールド部材５０を確実に保持することができる。   Furthermore, when the second shield member 50 is attached to the connector main body 10 in the connector main body 10, the protrusion 12 a that fits into the fitting portion 52 provided in the second shield member 50 is provided. When the shield member 50 is attached to the connector main body 10, the second shield member 50 can be reliably held.

また、コネクタ本体１０に回動自在に設けられた開閉部材３０を備え、開閉部材３０を所定の閉鎖位置まで回動するとフレキシブル回路１の後方の面と各端子２０とが圧接し、開閉部材３０を開放方向の所定位置まで回動するとフレキシブル回路１と各端子２０との圧接が解除されるように構成したので、フレキシブル回路１と各端子２０との接続信頼性を向上させることができる。   Further, the connector main body 10 is provided with an opening / closing member 30 rotatably provided. When the opening / closing member 30 is rotated to a predetermined closed position, the rear surface of the flexible circuit 1 and each terminal 20 are in pressure contact with each other, and the opening / closing member 30. Since the press contact between the flexible circuit 1 and each terminal 20 is released when the terminal is rotated to a predetermined position in the opening direction, the connection reliability between the flexible circuit 1 and each terminal 20 can be improved.

さらに、各端子２０に、フレキシブル回路１の後方の面側に接触する弾性片部２２と、第１のシールド部材４０を間にして弾性片部２２と対向する固定片部２１とを設けるとともに、固定片部２１と第１のシールド部材４０との間には固定片部２１に当接しながら開閉部材３０と一体に回動して第１のシールド部材４０を押圧する押圧部３１を設け、第１のシールド部材４０を、開閉部材３０を閉鎖位置まで回動すると、押圧部３１に押圧されながら弾性変形してフレキシブル回路１の前方の面に圧接するように形成したので、開閉部材３０の回動部分における外部からの電磁波を第１のシールド部材４０によって確実に遮断することができ、ＥＭＩ対策を強化することができる。また、第１のシールド部材４０には押圧部３１の押圧によるフレキシブル回路１への接触圧を付与することができるので、長期的な使用においても接触圧が低下することなく、接続信頼性を高めることができる。   Furthermore, each terminal 20 is provided with an elastic piece portion 22 that contacts the rear surface side of the flexible circuit 1 and a fixed piece portion 21 that faces the elastic piece portion 22 with the first shield member 40 therebetween, Between the fixed piece portion 21 and the first shield member 40, a pressing portion 31 that rotates integrally with the opening / closing member 30 and presses the first shield member 40 while being in contact with the fixed piece portion 21 is provided. When the opening / closing member 30 is rotated to the closed position, the one shield member 40 is elastically deformed while being pressed by the pressing portion 31 so as to be in pressure contact with the front surface of the flexible circuit 1. Electromagnetic waves from the outside in the moving part can be reliably blocked by the first shield member 40, and EMI countermeasures can be strengthened. Moreover, since the contact pressure to the flexible circuit 1 by the press of the press part 31 can be given to the 1st shield member 40, even if it uses for a long term, a contact pressure does not fall, but improves connection reliability. be able to.
