[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for connecting a flat cable and a printed wiring board, and more particularly to a small connector which facilitates mounting.

[0002]

2. Description of the Related Art A conventional connector for connecting a flat cable to a printed wiring board is disclosed in, for example, Japanese Patent Laid-Open No. 4-24208.
As disclosed in Japanese Patent Publication No. 7, a structure in which a printed circuit board is inserted into a connector and a slide means is slid to realize connection with a contact is general.

3 (a) and 3 (b) are cross-sectional views of such a conventional example before and after mounting a connector. FIG.
As shown in (a), a conventional connector 304 has an opening 301, a contact portion 303 for connection, and a slider portion 302 for fixing a cable, and a flexible printed circuit board 300 is printed. It is connected to the wiring board 305. First, the flexible printed board 300 is inserted into the opening 301 of the connector 304.

Next, as shown in FIG. 3B, after inserting the printed circuit board 300, the slider portion 302 is slid between the upper part of the connector 304 and the flexible printed circuit board 300 to contact the flexible printed circuit board 300 and the contact 303. And connect. In this way, the flexible printed circuit board 300 is held by the connector 304 and connected to the printed wiring board 305.

[0005]

In the conventional connector described above, when the flexible printed circuit board and the contact are connected, the operation of sliding the slider portion after inserting the distal end portion of the flexible printed circuit board into the opening is performed. ing.

However, since this flexible printed circuit board has high flexibility and the slider portion of the connector is small in size,
When the above-mentioned operation is performed manually, there is a drawback that workability is not easy. Further, even if such a connector is automatically mounted by using an assembly facility, there are drawbacks that the movement in mounting is complicated and it is effective, or the tact time becomes long.

An object of the present invention is to provide a connector suitable for facilitating such operational handling and suitable for automatic mounting on a printed wiring board by an assembling apparatus.

And a mounting bracket 205. The plurality of contacts 202 form lead terminals 200 for connecting to a printed wiring board (not shown) at one end, and the plurality of cable conductors 10 on the flat cable 100 side at the other end.
1st 1st, 2nd insulator part 102A, 10
A contact portion 201 for contacting the intermediate conductor portion not held by 2B is formed. Further, the substantially U-shaped housing 204 has a recess 203 formed at a position facing the L-shaped locking portion 103 of the cable-side connector portion 104, and the contact 20 is provided so that only the lead terminal 200 is led to the outside.
2 is arranged inside, and the cable side connector portion 1
The first insulator portion 102A of No. 04 is held at a predetermined position. The substantially U-shaped housing 204 of the package-side connector portion 207 has a taper portion that serves as a guide for mounting the cable-side connector portion 104 on the inner surface that forms the short side thereof. Further, the mounting brackets 205 are formed on both side surfaces of the substantially U-shaped housing 204 for fixing the package side connector portion 207 to the printed wiring board, and the mounting brackets 205 and the substantially U-shaped housing 204 are integrally formed by molding. Formed.

Hereinafter, the cable side connector portion 104 will be described.
