[Problems to be solved by the device]

 In the conventional FPC connector 50 as described above, the sliding direction of the slide cover member 52 with respect to the connector main body 51 is horizontal, so that it may be located close to the front of the connector main body 51 mounted on the board and other connectors. When an electronic component or the like is mounted, the slide cover member 52 cannot be slid with respect to the connector main body 51, so that it becomes difficult to lock and unlock the FPC. In other words, the conventional FPC connector 50 described above is required to have a space in advance for pulling out the slide cover member 52 or inserting the FPC in front of the connector when mounting the connector on the board. However, it cannot fully cope with high-density mounting of boards in recent years.

In view of the above point, the present invention is designed to easily lock and unlock the FPC even when another electronic component or the like is mounted in front of the connector body mounted on the board. It is intended to provide a connector for use.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of an FPC connector according to the present invention. An FPC connector 1 of this example comprises a connector body 10 mounted on a board and a slide cover slidably mounted on the connector body 10. It is composed of a member 20.

As can be seen from FIGS. 3 and 4, the connector body 10 has a box shape having an opening for inserting an FPC (reference numeral F) below the upper end 15 of the upper plate portion. Guide projections 12 having a substantially rectangular cross section for defining a sliding direction of a slide cover member 20 to be described later are provided on both side surface portions thereof so as to obliquely cross the both side surface portions, and the slide cover member is also provided. When the slide cover member 20 is pulled out, a locking projection 17 having a triangular cross-section for locking it when it is pushed into the connector body 10 and a retaining projection 19 for preventing the slide cover member 20 from slipping off when the slide cover member 20 is pulled out are provided. There is.

Inside the connector body 10, a large number of contact fittings 30A and 30B that are brought into contact with the FPC are fixed. As shown in detail in FIGS. 5 and 6, the contact fittings 30A and 30B include a base portion 31 fixed to the connector body 10, a bending portion 33 that rises upward from the base portion 31 and is bent, and a bending portion of the bending portion 33. The pressing piece portion 35 is connected to the portion 33, and the central portion of the pressing piece portion 35 is curved so as to project downward. The pressing piece portion 35 is capable of bending in the vertical direction, and the pressing convex portion 36 located at the tip of the pressing piece portion 35 is elastically brought into contact with the FPC.

Further, foot portions 32a and 32b are provided on the base side of the contact fittings 30A and 30B, respectively, and the foot portions 32a and 32b are connected to the wiring pattern of the board. In the connector body 10, a contact metal fitting 30A having a foot portion 32a formed on the front side and a contact metal fitting 30B having a foot portion 32b formed on the rear side are alternately arranged side by side.

On the other hand, the slide cover member 20 has a base portion 21 having an inclined pressing portion 23 and a pair of holding plate portions 22 provided at both ends of the base portion 21. Inside, there are provided parallel protrusions 27 having a parallelepiped cross section that are respectively locked by the locking projections 17 and the retaining projections 19, and the guide projections 12 provided on the connector body 10 are fitted therein. A groove-shaped guide portion 24 is provided to be fitted.

In the FPC connector 1 of this embodiment having such a configuration, when the slide cover member 20 is mounted on the connector body 10, the slide cover member 20 is attached to the guide protrusion 12 provided on the connector body 10. After fitting the groove-shaped guide portion 24 provided in the slide cover member 20, the slide cover member 20 is slid obliquely downward along the length direction of the projecting convex portion 12 and pushed into the connector body 10.

As a result, the locking projections 27 of the slide cover member 20 are locked to the locking projections 17 of the connector body 10 after the locking projections 19 and the locking projections 17 of the connector body 10 are crossed over, so that the slide cover member 20 is connected to the connector. It is attached to the main body 10. In this state, the upper plate front end 15 of the connector main body 10 contacts the contact end surface 26 of the slide cover member 20, and a gap for inserting and withdrawing the FPC is formed between the upper plate front end 15 and the inclined pressing portion 23. It is formed.

When locking the FPC, first, the slide cover member 20 is pulled obliquely upward from the state shown in FIG. 4 with respect to the connector body 10. Then, as shown in FIG. 3, the groove-shaped guide portion 24 of the slide cover member 20 is guided by the guide convex portion 12 of the connector body 10, and the slide cover member 20 is slanted with respect to the connector body 10. It slides upward and is pulled out.

In this state, the FPC is inserted into the connector main body 10 through the gap formed between the front end 15 of the upper plate portion and the inclined pressing portion 23, and the contact portions formed on the tip side of the FPC are contacted with each contact. The metal fittings 30A and 30B are positioned below the pressing piece portion 35, and in this state, the slide cover member 20 is pushed obliquely downward. Then, as shown in FIG. 4, the groove-shaped guide portion 24 of the slide cover member 20 is guided by the guide convex portion 12 of the connector body 10, and the slide cover member 20 slides obliquely downward with respect to the connector body 10. It is moved and pushed.

As a result, the tip of the FPC is clamped and held by the pressing convex portion 36 of the pressing piece portion 35 and the pressing portion 23, the FPC and the contact fittings 30A and 30B are electrically connected, and the FPC is locked. To be done. In this case, the FPC is elastically pressed by the pressing piece portion 35 of the contact fittings 30A and 30B, but since the pressing piece portion 35 has a curved central portion, it is made linear. Its spring characteristics are improved compared to the conventional one (FIG. 7), and sufficient pressing force can be obtained even if the horizontal length is shortened.

In this way, when the FPC is locked, the FPC is pulled out from the gap formed between the upper plate front end 15 of the connector body 10 and the inclined pressing portion 23 of the slide cover member 20. , The FPC may be drawn in a horizontal direction as shown by a solid line in FIG. 4, or may be in a vertical direction as shown by a chain line in FIG. 4, and the drawing direction can be set arbitrarily.

Therefore, even when other electronic components or the like are arranged around the FPC connector 1 of the present example mounted on the substrate, the other components are avoided in the set without interfering with those electronic components and the like. The FPC wiring can be done with.

On the other hand, when the FPC is unlocked, the slide cover member 20 is slid upward from the position shown in FIG. 4 and pulled out to the position shown in FIG. As a result, the holding condition of the FPC is released and the FPC is pulled out from the outlet.

Therefore, in the FPC connector 1 of the present example configured as described above, the slide cover member 20 is provided with the guide protrusion 12 and the groove guide provided on the connector body 10 and the slide cover member 20. The slide cover member 20 is guided by the portion 24 and slid in an oblique direction with respect to the connector main body 10. Therefore, when locking and unlocking the FPC, the slide cover member 20 is pulled out obliquely upward, not in front of the connector main body 10. It will be.

Therefore, even when another electronic component or the like is mounted in front of the connector body 10 mounted on the board, the FPC can be easily locked and unlocked, which means that the high density of the board is high. Implementation can be promoted.
