Description

本発明は中継用コネクタ、特に、２枚のフレキシブルプリント基板（以下、「ＦＰＣ」という）を相互に接続するため、ゼロインサーションフォース（ＺＩＦ）構造を備えた中継用コネクタあるいはバックロック式コネクタに関する。 The present invention relates to a relay connector, and more particularly to a relay connector or a backlock connector having a zero insertion force (ZIF) structure for connecting two flexible printed boards (hereinafter referred to as “FPC”) to each other. .

従来、ＦＰＣのためのＺＩＦ構造を備えた中継用コネクタとしては、例えば、ハウジング９に第一，第二のフレキシブル基板３，４を挿入して位置決めした後、スライドカバー２５をスライドさせることにより、前記フレキシブル基板３，４をコンタクト１１の両端部１７，１９に所定の接触圧でそれぞれ弾性接触させ、前記第一，第二のフレキシブル基板３，４を相互に電気接続するものがある（特許文献１参照）。
また、ＦＰＣのためのＺＩＦ構造を備えたバックロック式コネクタとしては、ハウジング２０に組み込んだ略Ｈ字形状の接触子１０のうち、回転ビーム１１をレバー３０で回動し、接触ビーム１２の接触部１６をＦＰＣ４０に接触させて電気接続するものがある（特許文献２参照）。
特開平９−１９９２４１号公報特開平１０−２０８８１０号公報 Conventionally, as a relay connector having a ZIF structure for an FPC, for example, after the first and second flexible boards 3 and 4 are inserted and positioned in the housing 9, the slide cover 25 is slid, There is one in which the flexible substrates 3 and 4 are elastically brought into contact with both end portions 17 and 19 of the contact 11 with a predetermined contact pressure, respectively, and the first and second flexible substrates 3 and 4 are electrically connected to each other (Patent Document). 1).
In addition, as a back lock type connector having a ZIF structure for FPC, a rotating beam 11 is rotated by a lever 30 in a substantially H-shaped contact 10 incorporated in a housing 20, and the contact of the contact beam 12 is achieved. There is one in which the portion 16 is brought into contact with the FPC 40 to be electrically connected (see Patent Document 2).

しかしながら、前記中継用コネクタにおいては、通常、フレキシブルな樹脂フィルムからなるフレキシブル基板４の先端部が補強シートで裏打ちされ、硬い板状体となっている。このため、例えば、前記ハウジング９に組み付けたフレキシブル基板４を前記ハウジング９の開口部に沿って図１（Ｂ）中の左方側に引き回すと、前記フレキシブル基板４の先端部が、その最先端を支点として回動し、コンタクト１１の端部１９から離れ、接触不良を生じるおそれがある。
一方、前記バックロック式コネクタにおいても、前記ハウジング２０に組み付けたＦＰＣ４０を前記ハウジング２０の開口部に沿って左方側に引き回すと、前記ＦＰＣ４０の先端部が、その最先端を支点として回動し、接触子１０の接触部１６から離れ、接触不良を生じるおそれがある。 However, in the relay connector, the tip of the flexible substrate 4 made of a flexible resin film is usually lined with a reinforcing sheet to form a hard plate. For this reason, for example, when the flexible substrate 4 assembled to the housing 9 is drawn to the left side in FIG. 1B along the opening of the housing 9, the distal end portion of the flexible substrate 4 is at its leading edge. May be pivoted to move away from the end 19 of the contact 11 to cause a contact failure.
On the other hand, also in the backlock connector, when the FPC 40 assembled to the housing 20 is drawn to the left side along the opening of the housing 20, the front end of the FPC 40 is rotated with its front end as a fulcrum. There is a possibility that contact failure may occur due to separation from the contact portion 16 of the contact 10.

本発明は、前記問題点に鑑み、ハウジングに組み付けたＦＰＣを上下のいずれの方向に引き回しても、接触不良が生じにくい中継用コネクタを提供することを課題とする。 In view of the above problems, an object of the present invention is to provide a relay connector that is less likely to cause poor contact even when the FPC assembled to the housing is routed in any direction.

本発明にかかる中継用コネクタは、前記課題を解決すべく、対向する正面および背面に相互に連通する開口部をそれぞれ設けたハウジングと、前記ハウジングの対向する両側面から一方側に平行に延在した一対の腕部で回動可能に支持された操作レバーと、一端部に可動爪を有し、かつ、他端部に操作部を有するとともに、前記ハウジングの背面の開口部から挿入，保持され、前記操作レバーの回動操作によって駆動される仮止め金具と、上下で対向する受動接点と第１能動接点とを一方側に配置し、かつ、前記第１能動接点と同一直線上に位置する第２能動接点を他方側に配置するとともに、前記ハウジングの開口部から挿入，保持され、前記操作レバーの回動操作によって駆動される接触子と、からなり、
前記ハウジングの開口部のうち、正面の開口部に、折れ曲がらないように補強シートで補強された第１フレキシブルプリント基板の一端部を挿入し、前記操作レバーを回動して前記仮止め金具の操作部を駆動し、その可動爪で前記第１レキシブルプリント基板を仮止めする一方、
前記ハウジングの背面の開口部に第２フレキシブルプリント基板の一端部を挿入し、前記操作レバーを更に回動することにより、前記第２フレキシブルプリント基板を介して前記接触子の第２能動接点を駆動し、前記第１フレキシブルプリント基板の一端部を前記接触子の受動接点と第１能動接点とで挟持し、前記第１フレキシブルプリント基板の一端部に設けた接続パッドを前記接触子に電気接続するとともに、前記第２フレキシブルプリント基板の一端部に設けた接続パッドを前記接触子の第２能動接点に電気接続する中継用コネクタであって、
前記第１フレキシブルプリント基板の一端部を挿入するハウジングの開口部の上下縁部のうち、前記第１能動接点に対応する縁部を、前記受動接点に対応する縁部よりも外方に迫り出すように突設した構成としてある。 The relay connector according to the present invention includes, in order to solve the above problems, a housing provided with openings that communicate with each other on the front surface and the back surface, and extending parallel to one side from the opposite side surfaces of the housing. An operation lever supported rotatably by the pair of arms, a movable claw at one end, an operation at the other end, and inserted and held from the opening on the back of the housing. , A temporary fitting that is driven by a turning operation of the operation lever, and a passive contact and a first active contact that are vertically opposed to each other are disposed on one side, and are located on the same straight line as the first active contact. A second active contact disposed on the other side, and a contactor inserted and held from the opening of the housing and driven by a turning operation of the operation lever,
One end of the first flexible printed circuit board reinforced with a reinforcing sheet so as not to bend is inserted into the front opening of the housing, and the operation lever is rotated to rotate the temporary fixing metal fitting. While driving the operation unit and temporarily fixing the first flexible printed circuit board with the movable claw,
One end of the second flexible printed circuit board is inserted into the opening on the back surface of the housing, and the operation lever is further rotated to drive the second active contact of the contact through the second flexible printed circuit board. Then, one end of the first flexible printed circuit board is sandwiched between the passive contact and the first active contact of the contact, and a connection pad provided on the one end of the first flexible printed circuit is electrically connected to the contact. And a relay connector for electrically connecting a connection pad provided at one end of the second flexible printed circuit board to the second active contact of the contact ,
Of the upper and lower edges of the opening of the housing into which one end of the first flexible printed circuit board is inserted, the edge corresponding to the first active contact protrudes outward from the edge corresponding to the passive contact. Thus, the projecting configuration is as follows.

本発明によれば、例えば、ＦＰＣを受動接点側に引き上げた場合には、ハウジングに挿入した前記ＦＰＣの一端部が硬い板状体であるので、その最先端を支点として傾斜する。このため、ＦＰＣの一端部上面がハウジングの上方縁部に当接しても、前記ＦＰＣの一端部上面に設けた接続パッドが受動接点により強く圧接し、接点圧を確保できるので、接触信頼性が低下することはない。逆に、ＦＰＣを能動接点側に引き下げた場合には、受動接点に対応する縁部よりも外方に迫り出している能動接点に対応する縁部が、ＦＰＣのハウジング内に挿入されたＦＰＣの先端部を強く位置規制し、前述のように傾斜することがない。このため、ＦＰＣの一端部の下面に設けた接続パッドが能動接点により強く圧接するだけでなく、ＦＰＣの一端部の上面に設けた接続パッドが受動接点から離れることがないので、接点圧が著しく低下せず、接触信頼性が低下しない。したがって、本発明によれば、ＦＰＣが上下に引き回されても、その先端部が接触子の受動接点および能動接点の少なくともいずれか一方に所定の接点圧で接触するので、高い接触信頼性を確保できる。
また、ＦＰＣの一端部の上下面のうち、いずれの面に接続パッドを設けたＦＰＣ（図示せず）であっても、所定の接点圧で接続でき、接続の自由度が大きい汎用性に優れた中継用コネクタが得られる。
特に、接触子の能動接点および受動接点が弾性変形可能であり、かつ、前記能動接点が受動接点側に付勢されているとき、例えば、ＦＰＣを受動接点側に引き上げた場合には、ハウジングに挿入した前記ＦＰＣの一端部が硬い板状体であるので、その最先端を支点として傾斜する。このため、ＦＰＣの一端部上面がハウジングの上方縁部に当接しても、前記ＦＰＣの一端部上面に設けた接続パッドが受動接点により強く圧接するとともに、前記ＦＰＣの一端部下面に設けた接続パッドが能動接点に所定の接点圧力で接触し続け、接触信頼性が低下することはない。逆に、ＦＰＣを能動接点側に引き下げた場合には、受動接点に対応する縁部よりも外方に迫り出している能動接点に対応する縁部が、ＦＰＣのハウジング内に挿入されたＦＰＣの先端部を強く位置規制し、前述のように傾斜することがない。このため、ＦＰＣの一端部の下面に設けた接続パッドが能動接点により強く圧接するだけでなく、ＦＰＣの一端部の上面に設けた接続パッドが受動接点から離れず、接点圧が著しく低下することがないので、接触信頼性が低下しない。したがって、ＦＰＣが上下に引き回されても、能動接点および受動接点の両方がＦＰＣの上下面に常に所定の接点圧で接触しているので、より一層優れた接触信頼性，汎用性を有する中継用コネクタが得られる。
さらに、一方の縁部が他方の縁部よりも迫り出しているので、ＦＰＣの一端部をハウジング内に挿入する際の位置決めが容易となり、作業性がより一層向上する。 According to the present invention, for example, when the FPC is pulled up to the passive contact side, one end portion of the FPC inserted into the housing is a hard plate-like body, and therefore, the FPC is inclined with the leading edge as a fulcrum. For this reason, even if the upper surface of one end of the FPC abuts on the upper edge of the housing, the connection pad provided on the upper surface of the one end of the FPC is strongly pressed by the passive contact, and the contact pressure can be secured. There is no decline. Conversely, when the FPC is pulled down to the active contact side, the edge portion corresponding to the active contact that protrudes outward from the edge portion corresponding to the passive contact is the FPC inserted into the FPC housing. The position of the tip portion is strongly regulated, and it does not tilt as described above. For this reason, not only the connection pad provided on the lower surface of one end of the FPC is strongly pressed by the active contact, but also the connection pad provided on the upper surface of the one end of the FPC does not move away from the passive contact. It does not decrease and contact reliability does not decrease. Therefore, according to the present invention, even when the FPC is drawn up and down, the tip of the FPC contacts at least one of the passive contact and the active contact of the contact with a predetermined contact pressure. It can be secured.
Moreover, even if it is FPC (not shown) which provided the connection pad in any surface among the upper and lower surfaces of the one end part of FPC, it can connect with predetermined contact pressure, and it is excellent in versatility with a large degree of freedom of connection. A relay connector can be obtained.
In particular, when the active contact and the passive contact of the contact are elastically deformable and the active contact is biased toward the passive contact, for example, when the FPC is pulled up toward the passive contact, Since one end portion of the inserted FPC is a hard plate-like body, the FPC is inclined with its leading edge as a fulcrum. For this reason, even if the upper surface of one end of the FPC contacts the upper edge of the housing, the connection pad provided on the upper surface of the one end of the FPC is strongly pressed by the passive contact, and the connection provided on the lower surface of the one end of the FPC. The pad continues to contact the active contact at a predetermined contact pressure, and contact reliability is not reduced. Conversely, when the FPC is pulled down to the active contact side, the edge corresponding to the active contact that protrudes outward from the edge corresponding to the passive contact is the FPC inserted into the FPC housing. The position of the tip portion is strongly regulated, and it does not tilt as described above. For this reason, not only the connection pad provided on the lower surface of one end of the FPC is strongly pressed by the active contact, but the connection pad provided on the upper surface of the one end of the FPC does not move away from the passive contact, and the contact pressure is significantly reduced. Since there is no contact reliability, contact reliability does not decrease. Therefore, even if the FPC is routed up and down, both the active contact and the passive contact are always in contact with the upper and lower surfaces of the FPC at a predetermined contact pressure, so that the relay has much better contact reliability and versatility. Connector is obtained.
Furthermore, since one edge protrudes from the other edge, positioning when inserting one end of the FPC into the housing is facilitated, and workability is further improved.

本発明にかかる実施形態としては、ハウジング内の受動接点を上方側に配置するとともに、第１能動接点を前記受動接点に対向するように下方側に配置する一方、ハウジングの開口部の下方縁部を、上方縁部よりも外方に迫り出すように突設しておいてもよい。
本実施形態によれば、前述と同様な効果が得られる。特に、斜め上方からＦＰＣの一端部をハウジング内に挿入する場合に、下方縁部に当接させて位置決めした後、ハウジング内に挿入でき、作業性がより一層向上する。 As an embodiment according to the present invention, the passive contact in the housing is arranged on the upper side, and the first active contact is arranged on the lower side so as to face the passive contact, while the lower edge of the opening of the housing May be provided so as to protrude outward from the upper edge.
According to this embodiment, the same effect as described above can be obtained. In particular, when one end of the FPC is inserted into the housing from obliquely above, the FPC can be inserted into the housing after being positioned in contact with the lower edge, further improving workability.

本発明にかかる他の実施形態としては、ハウジング内の受動接点を下方側に配置するとともに、第１能動接点を前記受動接点に対向するように上方側に配置する一方、ハウジングの開口部の上方縁部を、下方縁部よりも外方に迫り出すように突設しておいてもよい。
本実施形態によれば、前述と同様な効果が得られる。特に、斜め下方からＦＰＣの一端部をハウジング内に挿入する場合に、上方縁部に当接させて位置決めした後、ハウジング内に挿入でき、作業性がより一層向上するという効果がある。 As another embodiment of the present invention is to place a passive contact in the housing on the lower side, while placed on the upper side as the first active contact facing the passive contact, above the opening of the housing The edge portion may protrude from the lower edge portion so as to protrude outward.
According to this embodiment, the same effect as described above can be obtained. In particular, when one end portion of the FPC is inserted into the housing from obliquely below, the FPC can be inserted into the housing after being positioned in contact with the upper edge portion, and the workability is further improved.

Respectively. As shown in FIG. 4B, a press-fitting groove for press-fitting first and second contacts 30 and 40, which will be described later, into a receiving part 23 extending from the lower edge of the back side of the housing body 21. 24 and 25 are alternately provided at a predetermined pitch. In addition, press-fitting grooves 26 and 26 for press-fitting the temporary fitting 50 are formed on the outer sides of the press-fitting grooves 24 and 24 located at both ends, respectively. The arm portion 22 has a tapered surface 22a and a bearing portion 22b formed on the upper step portion of the inward surface. Further, in the lower step portion of the inward surface, a first recess 22c is formed immediately below the tapered surface 22a, and a second recess 22d is directly below the bearing portion 22b. Next, a third recess 22e is formed on the inner side of the bearing 22b and the second recess 22d.

一方、図４Ａに示すように、前記ハウジング２０の正面側の開口部２１ａから前記圧入溝２４，２５，２６の端部を目視可能である。また、前記ハウジング２０の正面側の両側縁部から上段部２７および下段部２８を側方にそれぞれ突設することにより、後述する第１ＦＰＣ７０を挿入できるスリット２１ｃが形成されている。ただし、前記上段部２７よりも前記下段部２８が外方に迫り出している。なお、前記開口部２１ａの奥側には、図３および図１３Ｂに示すように、挿入した第１ＦＰＣ７０の先端部が当接する位置決め部２１ｄが形成されている。 On the other hand, as shown in FIG. 4A, the end portions of the press-fit grooves 24, 25, and 26 can be seen from the opening 21 a on the front side of the housing 20. Further, by projecting the upper step 27 and the lower step 28 laterally from both side edge portions on the front side of the housing 20, a slit 21c into which a first FPC 70 described later can be inserted is formed. However, the lower step portion 28 protrudes outward from the upper step portion 27. In addition, as shown in FIGS. 3 and 13B, a positioning portion 21d with which the distal end portion of the inserted first FPC 70 abuts is formed on the back side of the opening portion 21a.

第１接触子３０は、図５に示すように、正面略Ｈ字形状を有する導電性板バネ材からなるものである。すなわち、連結部３１の上端部から両側方に上辺部３２を延在してある一方、その下端部から両側方に下辺部３３を延在してある。そして、前記上辺部３２の一端側に係合爪３２ａを形成してある一方、他端側に支点部３２ｂを設けてある。また、前記下辺部３３の一端側には第１能動接点３３ａを設けてある一方、他端側には第２能動接点３３ｂを設けてある。さらに、前記上辺部３２の下辺縁部うち、前記連結部３１の上端部近傍から受動接点３４ａが前記第１能動接点３３ａに対向するように延在しているとともに、係止用突起３４ｂが突設されている。そして、前記支点部３２ｂの近傍には圧入用突起３４ｃが突き出し加工で形成されている。 As shown in FIG. 5, the first contact 30 is made of a conductive leaf spring material having a substantially front H-shape. That is, while the upper side part 32 is extended on both sides from the upper end part of the connection part 31, the lower side part 33 is extended on both sides from the lower end part. An engaging claw 32a is formed on one end side of the upper side portion 32, and a fulcrum portion 32b is provided on the other end side. Further, a first active contact 33a is provided on one end side of the lower side portion 33, and a second active contact 33b is provided on the other end side. Further, among the lower edge portions of the upper side portion 32, the passive contact 34a extends from the vicinity of the upper end portion of the connecting portion 31 so as to face the first active contact 33a, and the locking projection 34b protrudes. It is installed. A press-fitting projection 34c is formed in the vicinity of the fulcrum portion 32b by extrusion.

そして、前記第１接触子３０は、図２Ｃに示すように、前記ハウジング２０に設けた圧入溝２４に開口部２１ａ側から圧入することにより、係止用突起３４ｂがハウジングの内部に係止するとともに、前記係合爪３２ａが前記開口部２１ａの上方縁部に係合して抜け止めされる。このとき、前記第１接触子３０の下辺部３３は連結部３１に吊り下げられ、ハウジング２０に接触していない。 Then, as shown in FIG. 2C, the first contact 30 is press-fitted into the press-fitting groove 24 provided in the housing 20 from the opening 21a side, so that the locking projection 34b is locked inside the housing. At the same time, the engaging claw 32a engages with the upper edge of the opening 21a and is prevented from coming off. At this time, the lower side portion 33 of the first contact 30 is suspended from the connecting portion 31 and is not in contact with the housing 20.

第２接触子４０は、図６に示すように、正面略Ｈ字形状を有する導電性板バネ材からなるものである。すなわち、連結部４１の上端部から両側方に上辺部４２を延在してある一方、その下端部から両側方に下辺部４３を延在してある。前記上辺部４２の一端側に係止爪４２ａを形成してある一方、他端側に係合爪４２ｂおよび支点部４２ｃを設けてある。また、前記下辺部４３の一端側には第１能動接点４３ａを設けてある一方、他端側には第２能動接点４３ｂを設けてある。さらに、前記上辺部４２の下辺縁部うち、前記連結部４１の上端部近傍から受動接点４４ａが前記第１能動接点４３ａに対向するように延在しているとともに、前記受動接点４４ａの基部に係止用突起４４ｂが突設されている。そして、前記上辺部４２の前記連結部４１の近傍に圧入用突起４４ｃが突き出し加工で形成されている。 As shown in FIG. 6, the second contact 40 is made of a conductive leaf spring material having a substantially H-shaped front surface. That is, while the upper side part 42 is extended from the upper end part of the connection part 41 to both sides, the lower side part 43 is extended from the lower end part to both sides. A locking claw 42a is formed on one end side of the upper side portion 42, while an engaging claw 42b and a fulcrum portion 42c are provided on the other end side. A first active contact 43a is provided on one end side of the lower side portion 43, and a second active contact 43b is provided on the other end side. Further, a passive contact 44a extends from the vicinity of the upper end portion of the connecting portion 41 in the lower edge of the upper side portion 42 so as to face the first active contact 43a, and at the base of the passive contact 44a. A locking projection 44b is provided in a protruding manner. A press-fitting protrusion 44c is formed in the vicinity of the connecting portion 41 of the upper side portion 42 by extrusion.

そして、前記第２接触子４０は、図２Ｂに示すように、前記ハウジング２０に設けた圧入溝２５に開口部２１ｂから圧入することにより、係止爪４２ａおよび係止用突起４４ｂがハウジング２０の内部に係止するとともに、前記係合爪４２ｂが開口部２１ａの上方縁部に係合して抜け止めされる。このとき、前記第２接触子４０の下辺部４３は連結部４１に吊り下げられ、ハウジング２０に接触していない。 As shown in FIG. 2B, the second contactor 40 is press-fitted into the press-fitting groove 25 provided in the housing 20 from the opening 21 b, so that the locking claw 42 a and the locking projection 44 b are formed on the housing 20. The engaging claw 42b engages with the upper edge of the opening 21a and is prevented from coming off. At this time, the lower side portion 43 of the second contactor 40 is suspended from the connecting portion 41 and is not in contact with the housing 20.

なお、図２Ｂ，２Ｃから明らかなように、前記ハウジング２０に前記第１，第２接触子３０，４０をそれぞれ組み込むことにより、第１接触子３０の受動接点３４ａおよび第１能動接点３３ａが、第２接触子４０の受動接点４４ａおよび第１能動接点４３ａよりもハウジング２０の奥側に位置する。このため、前記第１，第２接触子３０，４０は後述する第１ＦＰＣ７０にそれぞれ異なる位置で電気接続される。
同様に、第１接触子３０の第２能動接点３３ｂが、第２接触子４０の第２能動接点４３ｂよりもハウジング２０の奥側に位置する。このため、前記第１，第２接触子３０，４０は後述する第２ＦＰＣ８０にそれぞれ異なる位置で電気接続される。 2B and 2C, by incorporating the first and second contacts 30 and 40 into the housing 20, the passive contact 34a and the first active contact 33a of the first contact 30 are The second contact 40 is located on the back side of the housing 20 with respect to the passive contact 44a and the first active contact 43a. Therefore, the first and second contacts 30 and 40 are electrically connected to the first FPC 70 described later at different positions.
Similarly, the second active contact 33 b of the first contact 30 is located on the back side of the housing 20 with respect to the second active contact 43 b of the second contact 40. Therefore, the first and second contacts 30 and 40 are electrically connected to the second FPC 80 described later at different positions.

仮止め金具５０は、図７に示すように、正面略Ｈ字形状を有する板バネ材からなるものである。すなわち、連結部５１の上端部から両側方に上辺部５２を延在してある一方、その下端部から両側方に下辺部５３を延在してある。前記上辺部５２の一端側に係止爪５２ａを形成してある一方、他端側に係合爪５２ｂを設けてある。また、前記下辺部５３の一端側には可動爪５３ａを設けてある一方、他端側には操作部５３ｂを設けてある。さらに、前記上辺部５２の下辺縁部うち、前記連結部５１の上端部近傍に係止用突起５４ａが突設されている。 As shown in FIG. 7, the temporary fitting 50 is made of a leaf spring material having a substantially H-shape on the front side. That is, the upper side 52 extends from the upper end of the connecting portion 51 to both sides, while the lower side 53 extends from the lower end to both sides. An engaging claw 52a is formed on one end side of the upper side portion 52, and an engaging claw 52b is provided on the other end side. Further, a movable claw 53a is provided on one end side of the lower side portion 53, and an operation portion 53b is provided on the other end side. Further, a locking protrusion 54 a is provided in the vicinity of the upper end portion of the connecting portion 51 in the lower edge portion of the upper side portion 52.

そして、前記仮止め金具５０は、図１３Ｂに示すように、前記ハウジング２０に設けた圧入溝２６に圧入することにより、係止爪５２ａおよび係止用突起５４ａがハウジング２０の内部に係止するとともに、前記係合爪５２ｂが開口部２１ｂの上方縁部に係合して抜け止めされる。このとき、前記仮止め金具５０の下辺部５３は連結部５１に吊り下げられ、ハウジング２０に接触していない。 Then, as shown in FIG. 13B, the temporary fitting 50 is press-fitted into the press-fitting groove 26 provided in the housing 20, whereby the locking claw 52 a and the locking projection 54 a are locked inside the housing 20. At the same time, the engaging claw 52b engages with the upper edge of the opening 21b and is prevented from coming off. At this time, the lower side portion 53 of the temporary fitting 50 is suspended from the connecting portion 51 and is not in contact with the housing 20.

操作レバー６０は、図８に示すように、レバー本体６１の両側端部から延在部６２，６２をそれぞれ延在してある。前記レバー本体６１には、所定のピッチでスリット６３，６４が交互に並設されている。前記スリット６３，６４内には、前記第１，第２接触子３０，４０の支点部３２ｂ，４２ｃに圧接する操作部６３ａ，６４ａ（図２Ｂ，２Ｃ）を架け渡すように形成してある。 As shown in FIG. 8, the operation lever 60 has extending portions 62 and 62 extending from both end portions of the lever main body 61. In the lever body 61, slits 63 and 64 are alternately arranged at a predetermined pitch. In the slits 63 and 64, operation portions 63a and 64a (FIGS. 2B and 2C) are formed so as to be in pressure contact with the fulcrum portions 32b and 42c of the first and second contactors 30 and 40, respectively.

一方、前記延在部６２の外向面には、回動軸６５が同一軸心上にそれぞれ突設されているとともに、仮止め用突部６６が同一軸心上にそれぞれ突設されている。また、前記延在部６２の内向面には、押圧部６７がそれぞれ突設され、前記押圧部６７の外周面には圧接用リブ６７ａ（図８Ｃ）がそれぞれ形成されている。さらに、前記延在部６２の外周縁部には、係合爪部６８がそれぞれ突設されている。 On the other hand, on the outwardly facing surface of the extending portion 62, the rotation shafts 65 project from the same axis, and the temporary fixing projections 66 project from the same axis. Further, pressing portions 67 project from the inward surfaces of the extending portions 62, and pressure-contacting ribs 67a (FIG. 8C) are formed on the outer peripheral surface of the pressing portion 67, respectively. Further, an engaging claw portion 68 protrudes from the outer peripheral edge portion of the extending portion 62.

そして、前記操作レバー６０は、前記回動軸６５を前記ハウジング２０のテーパ面２２ａに沿って押し込み、前記腕部２２を弾性変形させることにより、前記回動軸６５を軸受け部２２ｂに嵌合するとともに、前記仮止め用突部６６を前記ハウジング２０の第１凹部２２ｃに嵌合する。 The operation lever 60 pushes the rotation shaft 65 along the tapered surface 22a of the housing 20 and elastically deforms the arm portion 22, thereby fitting the rotation shaft 65 into the bearing portion 22b. At the same time, the temporary fixing projection 66 is fitted into the first recess 22 c of the housing 20.

したがって、図１１および図１２に示すように、操作レバー６０を倒すことにより、回動軸６５を中心とし、仮止め用突部６６が第１，第２，第３凹部２２ｃ，２２ｄ，２２ｅに順次、係合するとともに、係合爪部６８がハウジング２０の第１凹部２２ｃに係合することにより、ロック状態となる。 Therefore, as shown in FIGS. 11 and 12, when the operation lever 60 is tilted, the temporary fixing projection 66 is formed in the first, second, and third recesses 22c, 22d, and 22e around the rotation shaft 65. The engaging claw portion 68 is engaged with the first recess 22c of the housing 20 in order to engage with each other, and the locked state is established.

第１ＦＰＣ７０は、図９に示すように、前記ハウジング２０への組み付け作業を容易にするため、フレキシブルな樹脂フィルムの一端部の下面に補強シート７１を裏打し、折れ曲がらない先端部７２を形成してある。また、前記先端部７２の上面には２種類の接続パッド７３，７４を所定のピッチで千鳥状に交互に設けてある。さらに、前記第１ＦＰＣは、その先端部７２の両側に仮止め用切り欠き部７５をそれぞれ形成してある。 As shown in FIG. 9, the first FPC 70 has a reinforcing sheet 71 lined on the lower surface of one end portion of a flexible resin film to form an end portion 72 that does not bend in order to facilitate the assembly operation to the housing 20. It is. In addition, two types of connection pads 73 and 74 are alternately provided in a staggered pattern at a predetermined pitch on the upper surface of the distal end portion 72. Further, the first FPC has a notch portion 75 for temporary fixing on both sides of the tip end portion 72, respectively.

第２ＦＰＣ８０は、図１０に示すように、前記ハウジング２０への組み付け作業を容易にするため、フレキシブルな樹脂フィルムの一端部の上面に補強シート８１を裏打し、折れ曲がらない先端部８２を形成してある。また、前記先端部８２の下面には２種類の接続パッド８３，８４を所定のピッチで千鳥状に設けてある。 As shown in FIG. 10, the second FPC 80 has a reinforcing sheet 81 lined on the upper surface of one end portion of a flexible resin film to form an end portion 82 that does not bend in order to facilitate the assembling work to the housing 20. It is. Further, two types of connection pads 83 and 84 are provided in a staggered pattern at a predetermined pitch on the lower surface of the distal end portion 82.

次に、前述の構成部品からなる中継用コンタクト１０に第１，第２ＦＰＣ７０，８０を接続する方法について説明する。
まず、図１３に示すように、操作レバー６０の仮止め用突部６６が第１凹部２２ｃに係合しているとともに、操作部６３ａ，６４ａが第１，第２接触子３０，４０の支点部４２ｃ，３２ｂに圧接することにより、ガタツキなく支持されている。 Next, a method for connecting the first and second FPCs 70 and 80 to the relay contact 10 composed of the above-described components will be described.
First, as shown in FIG. 13, the temporary fixing projection 66 of the operation lever 60 is engaged with the first recess 22 c, and the operation portions 63 a and 64 a are fulcrums of the first and second contacts 30 and 40. By pressing against the parts 42c and 32b, the parts 42c and 32b are supported without backlash.

ついで、図１４に示すように、ハウジング２０の開口部２１ａおよびスリット２１ｃから第１ＦＰＣ７０の先端部７２を挿入し、ハウジング２０内の位置決め部２１ｄに当接させる。そして、前記操作レバー６０を略垂直に引き起こすと、回動軸部６５を支点に前記操作レバー６０が回動し、仮止め用突部６６が第２凹部２２ｄに係合するとともに、前記操作レバー６０の押圧部６７が仮止め金具５０の操作部５３ｂを押し下げる。このため、仮止め金具５０の下辺部５３が連結部５１の下端部を支点に回動し、可動爪５３ａが第１ＦＰＣ７０の切り欠き部７５に係止することにより、第１ＦＰＣ７０が仮止めされる。このとき、操作レバー６０の仮止め用突部６６が第２凹部２２ｄに係合しているので、操作レバー６０が自動復帰せず、第１ＦＰＣ７０が脱落することもない。 Next, as shown in FIG. 14, the distal end portion 72 of the first FPC 70 is inserted through the opening 21 a and the slit 21 c of the housing 20 and is brought into contact with the positioning portion 21 d in the housing 20. When the operation lever 60 is raised substantially vertically, the operation lever 60 rotates about the rotation shaft portion 65, and the temporarily fixing projection 66 is engaged with the second recess 22d. The pressing portion 67 of 60 pushes down the operation portion 53b of the temporary fixing metal fitting 50. Therefore, the lower side portion 53 of the temporary fixing metal fitting 50 rotates around the lower end portion of the connecting portion 51, and the movable claw 53a is engaged with the cutout portion 75 of the first FPC 70, whereby the first FPC 70 is temporarily fixed. . At this time, since the temporarily fixing projection 66 of the operation lever 60 is engaged with the second recess 22d, the operation lever 60 does not automatically return and the first FPC 70 does not fall off.

ついで、図１５に示すように、第２ＦＰＣ８０をハウジング２０の開口部２１ｂから挿入した後、操作レバー６０を完全に倒すと、仮止め用突部６６が第３凹部２２ｅに嵌合するとともに、係合爪部６８が第１凹部２２ｃに係合する。このため、図２Ｂ，２Ｃに示すように、操作レバー６０のレバー本体６１が第２ＦＰＣ８０を介して第１，第２接触子３０，４０の第２能動接点３３ｂ，４３ｂを押し下げる。この結果、第２ＦＰＣ８０の接続パッド８３，８４と第１，第２接触子３０，４０の第２能動接点３３ｂ，４３ｂとがそれぞれ電気接続する。さらに、第１，第２接触子３０，４０の下辺部３３，４３が連結部３１，４１の下端部を支点としてそれぞれ回動し、第１接触子３０の受動接点３４ａと第１能動接点３３ａとが第１ＦＰＣ７０の接続パッド７３を挟持して電気接続する。同様に、第２接触子４０の受動接点４４ａと第１能動接点４３ａとが第１ＦＰＣ７０の接続パッド７４を挟持して電気接続し、接続作業が完了する。 Next, as shown in FIG. 15, after the second FPC 80 is inserted from the opening 21 b of the housing 20, when the operation lever 60 is completely tilted, the temporary fixing projection 66 is fitted into the third recess 22 e and The pawl portion 68 engages with the first recess 22c. Therefore, as shown in FIGS. 2B and 2C, the lever main body 61 of the operation lever 60 pushes down the second active contacts 33 b and 43 b of the first and second contacts 30 and 40 through the second FPC 80. As a result, the connection pads 83 and 84 of the second FPC 80 are electrically connected to the second active contacts 33b and 43b of the first and second contacts 30 and 40, respectively. Furthermore, the lower side portions 33 and 43 of the first and second contactors 30 and 40 are rotated about the lower end portions of the coupling portions 31 and 41, respectively, so that the passive contact 34a and the first active contact 33a of the first contactor 30 are rotated. Hold and electrically connect the connection pads 73 of the first FPC 70. Similarly, the passive contact 44a and the first active contact 43a of the second contactor 40 are electrically connected by sandwiching the connection pad 74 of the first FPC 70, and the connection operation is completed.

本実施形態によれば、ハウジング２０に第１ＦＰＣ７０を仮止めした後、ハウジング２０に第２ＦＰＣ８０を組み付けて電気接続でき、ハウジング２０に第１，第２ＦＰＣ７０，８０を同時に位置決めする必要がない。このため、第１，第２ＦＰＣ７０，８０の接続作業が容易となり、作業性が向上するという利点がある。 According to the present embodiment, after the first FPC 70 is temporarily fixed to the housing 20, the second FPC 80 can be assembled and electrically connected to the housing 20, and it is not necessary to position the first and second FPCs 70, 80 simultaneously on the housing 20. For this reason, there is an advantage that the connection work of the first and second FPCs 70 and 80 is facilitated and the workability is improved.

また、本実施形態よれば、図２Ｂ，２Ｃに示すように、第１ＦＰＣ７０をハウジング２０の上段部２７に沿って引き上げた場合には、前記第１ＦＰＣ７０のハウジング２０に挿入した先端部７２が硬い板状体であり、ハウジング２０の位置決め部２１ｄを支点として傾斜し、開口部２１ａの上方縁部に当接する。しかし、第１ＦＰＣ７０の接続パッド７３，７４が第１，第２接触子３０，４０の受動接点３４ａ，３４ａにより強く圧接するので、接触信頼性が低下することはない。また、第１，第２接触子３０，４０の第１能動接点３３ａ，４３ａは上方に付勢されているので、著しく接点圧が低下することはない。 Further, according to the present embodiment, as shown in FIGS. 2B and 2C, when the first FPC 70 is pulled up along the upper step portion 27 of the housing 20, the distal end portion 72 inserted into the housing 20 of the first FPC 70 is a hard plate. It is in the form of a body, is inclined with the positioning portion 21d of the housing 20 as a fulcrum, and abuts on the upper edge of the opening 21a. However, since the connection pads 73 and 74 of the first FPC 70 are strongly pressed by the passive contacts 34a and 34a of the first and second contacts 30 and 40, the contact reliability is not lowered. Further, since the first active contacts 33a and 43a of the first and second contactors 30 and 40 are biased upward, the contact pressure does not significantly decrease.

一方、第１ＦＰＣ７０をハウジング２０の下段部２８に沿って引き下げた場合には、ハウジング２０の下段部２８が上段部２７よりも迫り出している。このため、第１ＦＰＣ７０のハウジング２０内に挿入された先端部７２が強く位置規制され、前述のように傾斜することがない。この結果、第１ＦＰＣ７０の接続パッド７３，７４に対する第１，第２接触子３０，４０の受動接点３３ａ，４３ａおよび第１能動接点３３ａ，４３ａの接点圧がそれぞれ著しく低下することがなく、接触信頼性が低下しない。特に、第１，第２接触子３０，４０の第１能動接点３３ａ，４３ａは上方に付勢されているので、著しい接点圧の低下を防止できる。さらに、受動接点３４ａ，４４ａは若干の弾性変形が可能であるので、接触信頼性が著しく低下することはない。 On the other hand, when the first FPC 70 is pulled down along the lower step portion 28 of the housing 20, the lower step portion 28 of the housing 20 protrudes from the upper step portion 27. For this reason, the front-end | tip part 72 inserted in the housing 20 of 1st FPC70 is position-controlled strongly, and does not incline as mentioned above. As a result, the contact pressures of the passive contacts 33a and 43a and the first active contacts 33a and 43a of the first and second contacts 30 and 40 with respect to the connection pads 73 and 74 of the first FPC 70 are not significantly reduced, and the contact reliability Sex does not decrease. In particular, since the first active contacts 33a and 43a of the first and second contacts 30 and 40 are biased upward, a significant decrease in contact pressure can be prevented. Furthermore, since the passive contacts 34a and 44a can be slightly elastically deformed, the contact reliability is not significantly reduced.

このため、本実施形態よれば、第１ＦＰＣ７０が上下に引き回されても、その接点パッド７３，７４が第１，第２接触子３０，４０の受動接点３３ａ，４３ａおよび第１能動接点３４ａ，４４ａに接触している。このため、先端部の下面に接続パッドを設けたＦＰＣ（図示せず）を接続しても、接触信頼性を低下させることがなく、接続の自由度が大きい汎用性に優れた中継用コネクタ１０が得られる。また、下段部２８が上段部２７よりも迫り出しているので、第１ＦＰＣ７０をハウジング２０に挿入する際の位置決めが容易となり、接続作業性がより一層向上するという利点がある。 Therefore, according to the present embodiment, even if the first FPC 70 is drawn up and down, the contact pads 73 and 74 are the passive contacts 33a and 43a and the first active contacts 34a and 34a of the first and second contacts 30 and 40, respectively. 44a is in contact. For this reason, even if an FPC (not shown) provided with a connection pad on the lower surface of the tip is connected, the contact reliability is not lowered, and the relay connector 10 having a high degree of freedom of connection and excellent versatility. Is obtained. Further, since the lower step portion 28 protrudes more than the upper step portion 27, there is an advantage that the positioning when the first FPC 70 is inserted into the housing 20 is facilitated, and the connection workability is further improved.

第２実施形態は、図１６および図１７に示すように、プリント基板に実装できる、いわゆるバックロック式中継用コネクタ１１に適用した場合である。バックロック式中継用コネクタ１１とは、ハウジングにおけるＦＰＣの挿入位置と操作レバーの取付位置とが反対側に位置している中継用コネクタをいう。 As shown in FIGS. 16 and 17, the second embodiment is applied to a so-called backlock relay connector 11 that can be mounted on a printed circuit board. The backlock relay connector 11 is a relay connector in which the FPC insertion position in the housing and the operation lever mounting position are located on the opposite sides.

本実施形態にかかるハウジング２０は、図１７Ｂに示すように、ＦＰＣ（図示せず）を挿入する開口部２１ａの両側縁部に上段部２７と下段部２７とが突設されている。特に、前記上段部２７は前記下段部２８よりも外方に迫り出した位置にあり、第１実施形態と同様、ＦＰＣの上下方向の引き回しによる不具合を防止できる。 As shown in FIG. 17B, the housing 20 according to the present embodiment has an upper step portion 27 and a lower step portion 27 protruding from both side edges of an opening portion 21a into which an FPC (not shown) is inserted. In particular, the upper step portion 27 is located at a position that protrudes outward from the lower step portion 28, and, as in the first embodiment, it is possible to prevent inconveniences caused by the FPC being routed in the vertical direction.

また、接触子９０は、正面略Ｈ字形状を有する導電性板バネ材からなるものである。すなわち、連結部９１の上端部から両側方に上辺部９２を延在してある一方、その下端部から両側方に下辺部９３を延在してある。前記上辺部９２の一端側に能動接点９２ａを形成してある一方、他端側に操作部９２ｂを設けてある。また、前記下辺部９３の一端側には係止爪９３ａを設けてある一方、他端側には支点部９３ｂを設けてある。さらに、前記下辺部９３の上辺縁部うち、前記連結部９１の下端部近傍から受動接点９４が前記能動接点９２ａに対向するように延在している。 The contact 90 is made of a conductive leaf spring material having a substantially H-shape on the front side. That is, the upper side 92 extends from the upper end of the connecting portion 91 to both sides, while the lower side 93 extends from the lower end to both sides. An active contact 92a is formed on one end side of the upper side portion 92, and an operation portion 92b is provided on the other end side. A locking claw 93a is provided on one end side of the lower side portion 93, and a fulcrum portion 93b is provided on the other end side. Further, a passive contact 94 extends from the vicinity of the lower end portion of the connecting portion 91 in the upper edge portion of the lower side portion 93 so as to face the active contact 92a.

そして、前記接触子９０は、前記ハウジング２０に設けた圧入溝２５に圧入することにより、係止爪９３ａがハウジング２０内に係止して抜け止めされる。このとき、前記接触子９０の上辺部９２は連結部９１に支持され、ハウジング２０に接触していない。このため、前記ハウジング２０に取り付けた操作レバー６０を回動することにより、前記上辺部９２の操作部９２ｂを押圧部６９が押し上げ、連結部９１の上端部を支点として前記上辺部９２が回動し、図示しないＦＰＣの接続パッド部を受動接点９４と能動接点９２ａとで挟持して電気接続する。他は、前述の第１実施形態とほぼ同様であるので、同一部分に同一番号を附して説明を省略する。 The contact 90 is press-fitted into the press-fitting groove 25 provided in the housing 20, whereby the locking claw 93 a is locked in the housing 20 and is prevented from coming off. At this time, the upper side portion 92 of the contact 90 is supported by the connecting portion 91 and is not in contact with the housing 20. Therefore, by rotating the operating lever 60 attached to the housing 20, the pressing portion 69 pushes up the operating portion 92b of the upper side portion 92, and the upper side portion 92 rotates with the upper end portion of the connecting portion 91 as a fulcrum. Then, a connection pad portion of the FPC (not shown) is sandwiched between the passive contact 94 and the active contact 92a to be electrically connected. Others are almost the same as those of the first embodiment, and the same parts are denoted by the same reference numerals and the description thereof is omitted.

本発明にかかる中継用コネクタは、前述の中継用コネクタおよびバックロックタイプのコネクタ以外の中継用コネクタにも適用できる。 The relay connector according to the present invention can also be applied to relay connectors other than the relay connector and the back lock type connector described above.
