[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is for an FPC that is adapted to lock a flexible printed circuit board (hereinafter referred to as FPC) inserted in the connector body by a slide cover member slidably mounted on the connector body mounted on the board. Regarding electrical connectors.

[0002]

[Prior art]

 Conventionally, an FPC electrical connector of this type having the configuration shown in FIG. 3 has been implemented, and this will be described.

As shown in the figure, a conventional FPC electrical connector 1 is composed of a connector body 2 mounted on a substrate and a slide cover member 3 slidably mounted on the connector body 2. The main body 2 has a box shape having an opening 2a for inserting the FPC 4 on the front side thereof, and a plurality of contact metal fittings 5 contacting the FPC 4 are fixedly arranged inside thereof.

Here, the contact fitting 5 is composed of a base portion 5a fixed to the connector main body 2 and a linear pressing piece portion 5b which rises from the base portion 5a and is bent, and a tip 5c of the pressing piece portion 5b is formed. The FPC 4 is elastically contacted. Further, a foot portion 5d is provided on the base portion 5a of the contact fitting 5 so as to project to the outside of the connector body 2, and the foot portion 5d is electrically connected to a wiring pattern of a substrate (not shown). In the connector body 2, the contact fittings 5 with the feet 5d formed on the front side and the contact fittings 5 formed on the rear side are alternately arranged in parallel.

Next, the slide cover member 3 presses the insertion opening 3 a having the tapered portion 3 b into which the FPC 4 is guided and inserted, and the FPC 4 inserted into the connector body 2 from the insertion opening 3 a against the contact fitting 5. The pressing portion 3c is provided for the purpose.

Next, the assembled state of the electrical connector 1 will be described. As shown in the cross-sectional view of FIG. 4, when the FPC 4 is locked, the insertion port 3a of the slide cover member 3 pulled out from the connector body 2 is inserted. The FPC 4 is inserted from above, the contact portion formed on the tip side of the FPC 4 is positioned below the pressing piece portion 5b of the contact fitting 5 in the connector body 2, and the slide cover member 3 is slid horizontally in this state. Move and push in. As a result, the tip portion of the FPC 4 is held between the tip 5c of the pressing piece portion 5b and the pressing portion 3c, and the FPC 4 and the contact fitting 5 are electrically connected and the FPC 4 is locked. To be done.

Further, when the FPC 4 is taken out, the slide cover member 3 is slid in the horizontal direction and pulled out, whereby the holding condition of the FPC 4 is released and the FPC 4 is pulled out.

[0008]

[Problems to be solved by the device]

 However, in the above-mentioned conventional FPC electrical connector 1, the insertion port 3a of the slide cover member 3 into which the FPC 4 is inserted is simply provided with the tapered portions 3b above and below the insertion port with respect to the horizontal direction. It is configured to guide the tip.

Therefore, when the FPC 4 is inserted from the horizontal direction, the tip end of the FPC 4 is guided by the tapered portions 3b formed above and below the insertion opening 3a and is inserted into the connector body 2. As shown in the figure, when it is inserted obliquely from above, there is a problem that the tapered portion 3b does not act as a guide and smooth insertion cannot be performed.

Further, when the FPC 4 is inserted into the connector body 2, only the front end portion of the FPC 4 is locked, and in the vicinity of the insertion opening 3a of the slide cover member 3, a vertical gap is formed by the formed tapered portion 3b. However, there is also a problem that the FPC 4 is easily bent downward.

[0011]

[Means for Solving the Problems]

 Therefore, as a means for solving the above-mentioned problems, the present invention provides a connector main body to which a plurality of contact metal fittings that come into contact with an inserted flexible printed circuit board are fixed, and slidably mounted on the connector main body. An electric connector for a flexible printed circuit board, comprising: a slide cover member that presses and locks a flexible printed circuit board inserted in the connector body onto the contact fitting, the flexible printed circuit board insertion port of the slide cover member. It has a structure in which a protruding flat surface portion that protrudes outward in the horizontal direction is provided.

[0012]

[Action]

 With the above configuration, the FPC is easily guided and inserted into the insertion opening even when the FPC is inserted obliquely from above by the protruding flat surface portion provided in the insertion opening of the slide cover member. In addition, after the insertion, the protruding flat surface portion supports the downward direction to prevent bending.

[0013]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are sectional views showing an embodiment of an electric connector for an FPC according to the present invention.

As shown in the figure, the FPC electrical connector 10 includes a connector body 11 mounted on a substrate (not shown), and a slide cover member 12 slidably mounted on the connector body 11. The connector main body 11 is formed into a box shape having an opening 11a for inserting the FPC 4, and a plurality of contact metal fittings 13 that come into contact with the FPC 4 are fixedly arranged inside.

Here, the connector fitting 13 is formed of a base portion 13a fixed to the connector body 11 and a linear pressing piece portion 13b that is raised from the base portion 13a and bent, as in the conventional case. The tip 13c of the portion 13b elastically contacts the tip contact portion of the FPC 4. Further, a foot portion 13d is provided on the base portion 13a so as to project to the outside of the connector body 11, and is electrically connected to a wiring pattern (not shown). Further, as in the conventional structure, the contact metal fitting 13 has contact metal fittings 13 formed on the front side and contact metal fittings 13 formed on the rear side alternately arranged.

Subsequently, the slide cover member 12 has an insertion opening 14 provided with an upper end side taper portion 12a into which the FPC 4 is guided and inserted, and a protruding flat surface portion 12b protruding outward in the horizontal direction, and a contact metal fitting 13. The structure is provided with a pressing portion 12c for pressing the tip contact portion of the FPC 4 inserted in the.

Next, the assembled state of the electrical connector 10 will be described. As shown in FIG. 2, when the FPC 4 is locked to the connector body 11, the slide cover member 12 pulled out from the connector body 11 is inserted. When the FPC 4 is inserted obliquely from above through the opening 14, the tip of the FPC 4 comes into contact with the protruding flat surface portion 12b and is guided and inserted toward the insertion opening 14 side. As a result, the contact portion formed on the front end side of the FPC 4 is positioned below the pressing piece portion 13b of the contact tool 13, and in this state, the slide cover member 12 is slid toward the horizontal connector body 11 side. The FPC 4 is electrically connected and locked to the connector body 11 by pressing and pushing the tip of the FPC 4 between the tip 13c of the pressing piece 13b and the pressing portion 12c of the slide cover member 12 to electrically connect the FPC 4 to the connector body 11. .

Further, when the FPC 4 is taken out, the slide cover member 12 is again slid in the horizontal direction and pulled out, whereby the holding state of the pinching pressure of the FPC 4 is released and the FPC 4 is pulled out.

[0019]

[Effect of device]

 Therefore, according to the FPC electric connector of the present invention having the above-described configuration, the FPC is obliquely provided from above from the above because the slide cover member of the electric connector is provided with the protruding flat surface portion protruding outward in the horizontal direction. Even in the insertion work, the FPC comes into contact with the protruding flat surface portion and is easily guided and inserted into the insertion opening, so that the FPC can be provided with a degree of freedom in the insertion direction, thereby improving workability. be able to. Further, since the inserted FPC is positioned and held from below by the protruding flat surface portion in the sandwiched state, it is possible to obtain an effect that it is possible to prevent the occurrence of bending after the insertion locking. is there.
