Description of the Invention: [Technical Field] The present invention relates to a connector, and more particularly to a relay connector or a rear locking connector having a zero insertion force (ZIF) structure for making two flexible prints The substrates (hereinafter referred to as "FPC") are connected to each other. [Prior Art] Previously, a relay connector having a ZIF structure for an FPC has, for example, a method of inserting a housing into the first and second flexible substrates 3, 4 for positioning by sliding the sliding cover 25 The flexible substrates 3 and 4 are elastically contacted at the both end portions 17 and 19 of the contact member 1 by a predetermined contact pressure, so that the first and second flexible substrates 3 and 4 are electrically connected to each other. (refer to Patent Document 1). Further, a relay connector having a ZIF structure for FPC is provided in a substantially meandering contact member 10 incorporated in the outer casing 20, and the lever 30 is rotated by the rotating beam 11, so that the contact portion 16 of the contact beam 12 contacts. It is electrically connected to the FPC 40 (refer to Patent Document 2). [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. The reinforcing plate is padded from the inner surface to the front end portion of the flexible substrate 4 made of a flexible resin film to form a hard plate-like body. Therefore, for example, when the flexible substrate 4 combined with the outer casing 9 is pulled to the left side in the first figure (Β) along the opening of the outer casing 9, the front end portion of the flexible substrate 4 is the most The front end rotates as a fulcrum and deviates from the end portion 149 of the contact member 1 1 to cause a defect in contact. On the other hand, in the rear lock type connector, when the FPC 40 assembled in the outer casing 20 of the 1298214 is pulled to the left side along the opening of the outer casing 20, the front end portion of the FPC 40 is the front end of the FPC 40. The fulcrum rotates and deviates from the contact portion 16 of the contact member 10, and there is a problem that contact failure occurs. The present invention has been made in view of the above problems, and an object thereof is to provide a connector which is less likely to cause contact failure even when the FPC assembled in the casing is pulled up to any direction. In order to solve the above problems, the connector according to the present invention is reinforced by a reinforcing plate so as not to be bent, and is held in the casing by the driven contact and the active contact of the contact member held in the casing. One end portion of the flexible printed circuit board, and a connection pad provided at one end portion of the flexible printed circuit board is electrically connected to the contact member, and is configured to be inserted into an opening portion of the outer casing at one end portion of the flexible printed circuit board. Among the upper and lower edge portions, an edge portion corresponding to the driven contact is protruded to protrude outward from an edge portion corresponding to the driven contact. According to the present invention, for example, when the FPC is pulled up to the driven contact side, since one end portion of the FPC inserted into the casing is a hard plate-like body, the front end is inclined as a fulcrum. Therefore, even if the one end portion of the FPC abuts on the upper edge portion of the outer casing, the connection pads provided on the upper end of the FPC are still strongly pressed by the driven contacts, thereby ensuring the contact pressure, and thus the contact is not lowered. Reliability. Conversely, when the FPC is pulled down to the active contact side, the corresponding edge of the active contact is pushed out from the corresponding edge of the driven contact, and the front end of the FPC inserted in the FPC housing is strongly defined. There will be a situation as inclined as described above. Therefore, the connection pads disposed under the FPC-ends are not only strongly crimped by the active contacts, and since the connection pads provided on the FPC-ends do not deviate from the driven contacts, the contact pressure does not significantly Reduces the reliability of the 1298214 without reducing contact. Therefore, according to the present invention, even if the FPC is pulled up and down, the front end portion is pressed into contact with at least one of the driven contact and the active contact of the contact member at a predetermined contact position, thereby ensuring high contact reliability. Moreover, even if any one of the upper and lower faces of the FPC-end portion is provided with an FPC (not shown) for connecting pads, the contact connection can be predetermined, and a connector having high connection freedom and good versatility can be obtained. . In particular, the active contact and the driven contact of the contact point are elastically deformable, and when the active contact applies a force to the driven contact side, for example, when the FPC is pulled up to the driven side, the contact side is inserted due to The aforementioned FPC-end portion of the outer casing is a hard plate-like body, and therefore is inclined with its foremost end as a fulcrum. Therefore, even if the FPC-end portion abuts on the upper edge of the outer casing, the connection pads provided on the FPC-end portion are strongly crimped by the driven contact, and the connection welding is provided under the FPC-end portion. The pad is continuously contacted at the active contact with a predetermined contact pressure without a situation in which contact reliability is lowered.

Further, a fastening claw portion 68 is protruded from the outer peripheral edge portion of the extending portion 62. Then, the operating lever 60 pushes the rotating shaft 65 along the tapered surface 22a of the outer casing 20, and the rotating shaft 65 is fitted to the bearing receiving portion by elastically deforming the arm portion 22. 22b, the temporary fixing projection 66 is fitted to the first recess 22c of the outer casing 20. Therefore, as shown in Fig. 11 and Fig. 12, the temporary fixing projections 66 are sequentially engaged with the first and second ends with the rotation shaft 65 as the center by the manner in which the operating lever 60 is volted. The third recessed portions 22c, 22d, and 22e are locked in a state in which the engaging claw portion 68 is engaged with the first recessed portion 22c of the outer casing 20. As shown in Fig. 9, the first FPC 70 is formed so as to facilitate the assembly work on the outer casing 20, and the reinforcing plate 71 is placed on the lower surface of one end portion of the flexible resin film from the inner surface to form a front end portion 72 that is not bent. . Further, two kinds of connection pads 73 and 74 are alternately provided in a zigzag shape at a predetermined pitch on the front end portion 72. Further, the first FPC is formed on both sides of the front end portion 72, and each of the temporary B fixing notch portions 75 is formed. As shown in Fig. 10, in the second FPC 80, in order to facilitate the assembly work of the outer casing 20, the reinforcing plate 81 is placed on the upper surface of one end portion of the flexible resin film from the inner surface to form a front end portion 8 2 which is not bent. . Further, two kinds of connection pads 83 and 84 are alternately formed in a zigzag shape at a predetermined pitch below the front end portion 8 2 . Next, a method of 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. 1, the temporary fixing projections 6 of the operating lever 60 are engaged with the first recessed portion 22c, and are crimped to the first, -13-1298214 by the operating portions 63a and 64a. The fulcrum portions 42c and 32b of the second contacts 30 and 40 are supported so as not to be shaken. Then, as shown in Fig. 14, the distal end portion 72 of the first FPC 70 is inserted from the opening 21a and the slit 21c of the outer casing 20, and abuts against the positioning portion 21d in the outer casing 20. When the operation lever 60 is pulled up substantially vertically, the operation lever 60 is pivoted about the rotation shaft portion 65, and the temporary fixing projection 66 is engaged with the second recess 22d, and the operation lever 60 is pushed. The pressing portion 67 pushes down the operation portion 53b of the temporary fixing member 50. Therefore, the lower side portion 53 of the temporary fixing member 50 is pivoted with the lower end portion of the connecting portion 51 as a fulcrum, and the first FPC 70 is engaged by the movable claw 53a being fastened to the notch portion 75 of the first FPC 70. At this time, since the temporary fixing projection 66 of the operating lever 60 is engaged with the second recess 22d, the operating lever 60 is not automatically restored, and the first FPC 70 does not fall off. Then, as shown in Fig. 15, after the second FPC 80 is inserted from the opening 21b of the casing 20, when the operating lever 60 is completely collapsed, the temporary fixing projection 66 is fitted into the third recess 22e, and the claw portion is engaged. 68 is engaged 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 33b and 43b of the first and second contacts 30 and 40 via the second FPC 80. As a result, the connection pads 83 and 84 of the second FPC 80 and the second active contacts 33b and 43b of the first and second contacts 30 and 40 are electrically connected to each other. Further, the lower side portions 33 and 43 of the first and second contact members 30 and 40 are rotated by the lower end portions of the coupling portions 31 and 41 as fulcrums, and the driven contact 34a of the first contact member 30 and the first active connection are provided. Point 33a holds the connection pads 73 of the first FPC 70 and is electrically connected. Similarly, the driven contact 44a of the second contact 40 and the first active contact 43a hold the connection pads 74 of the first FPC 70 and are electrically connected to complete the connection work. According to the present embodiment, after the first FPC 70 is temporarily fixed to the casing 20, the second FPC 80 can be assembled to the casing 20 and electrically connected, and the first and the -14-1298214 2FPCs 70 and 80 need not be simultaneously positioned in the casing 20. Therefore, the connection work of the first and second FPCs 70 and 80 is facilitated, and the workability is improved. According to the present embodiment, as shown in FIGS. 2B and 2C, when the first FPC 70 is pulled up along the upper portion 27 of the casing 20, the front end portion 72 of the casing 20 of the first FPC 70 is inserted into a hard plate-like body. And the positioning portion 21d of the outer casing 20 is used as a fulcrum, and abuts against the upper edge portion of the opening portion 21a. However, the connection pads 7 3 and 7 4 of the first FPC 70 are strongly crimped by the driven contacts 3 4 a and 3 4 a of the first and second contacts 30 and 40, so that the contact is not reliably reduced. Sexual situation. Further, the first active contacts 33a and 43a of the first and second contacts 30 and 40 are biased upward, so that the contact pressure is not significantly lowered. On the other hand, when the first FPC 70 is pulled down along the lower portion 28 of the outer casing 20, the lower portion 28 of the outer casing 20 projects more than the upper portion 27. Therefore, the front end portion 72 inserted into the outer casing 20 of the first FPC 70 is strongly defined at a position without the aforementioned inclination. As a result, the contact pressures of the driven contacts 33a and 43a of the first and second contacts 30 and 40 and the first active contacts 33a and 43a are not applied to the connection pads 73 and 74 of the first FPC 70. Significantly reduced conditions without reducing contact reliability. In particular, since the first active contacts 3 3 a and 4 3 a of the first and second contacts 30 and 40 are biased upward, it is possible to prevent the contact pressure from being remarkably lowered. Further, the driven contacts 34a, 44a can be elastically deformed a certain number, so that there is no case where the contact reliability is remarkably lowered. Therefore, according to the present embodiment, even when the first FPC 70 is pulled up and down, the contact pads 73 and 74 are in contact with the driven contacts 3 3 a and 4 3 a of the first and second contacts 30 and 40, and The first active contact is 3 4 a, 4 4 a. Therefore, even if an FPC (not shown) provided with a connection pad is connected under the front end portion, the contact reliability is not lowered, and a relay connection having a large degree of connection freedom and good versatility is obtained. 15-1298214 • Connector 1 0. Further, the lower portion 28 is pushed out than the upper portion 27, so that it is easy to position the first 1F P C 70 into the outer casing 20, and there is an advantage in that the connection workability is further improved. The second embodiment is as shown in Figs. 16 and 17 and can be attached to a printed board, that is, to the case of the rear lock type connector 1 1. The rear lock type connector 1 1 refers to a connector in which the FPC insertion position and the operation lever are mounted on the opposite side. In the casing 20 according to the present embodiment, as shown in Fig. 17, the upper portion 27 and the lower portion 27 are protruded from both side edges of the opening portion 21a (not shown) to be inserted into the > FPC. In particular, the upper portion 27 is located outwardly from the lower portion 28, and similarly to the first embodiment, it is possible to prevent the FPC from being pulled up and down. Further, the contact member 90 is composed of a conductive leaf spring material having a substantially meandering shape on the front surface. That is, the upper side portion 92' extends from both sides of the upper end portion of the joint portion 9.1, and the lower side portion 93 extends from both sides of the lower end portion. The upper side portion 92 is formed with an active contact 92a on the end side and an operation portion 92b on the other end side. Further, the lower side portion 9 3 is provided with a locking claw 9 3 a on one end side, and a fulcrum portion 93b is provided on the other end side. Further, among the upper edge portions of the lower side portion 93, the "moving contact 94" extends from the vicinity of the lower end portion of the connecting portion 9 1 so as to face the main contact 92a. Then, the contact member 90 is biased into the casing 20 by press-fitting into the press-fitting groove 25 of the outer casing 20 to be stopped. At this time, the upper side portion 92 of the aforementioned contact member 90 is supported by the connecting portion 91' not contacting the outer casing 20. Therefore, by pressing the operation lever 60 attached to the outer casing 20, the pressing portion 69 pushes up the upper side portion 92© operation portion 92b to pivot the upper end portion of the joint portion -16 - 1298214 9 1 as a fulcrum. The portion 92 is electrically connected to the connection pad portion of the FPC (not shown) by the driven contact 94 and the active contact 92a. The other points are substantially the same as in the first embodiment, and the same reference numerals will be given to the same portions, and description thereof will be omitted. The connector according to the present invention can also be applied to connectors other than the above-described relay connector and rear lock type connector.
