The retention of the PC 6 in the insertion / removal direction from the slider 9 is achieved, and the positioning in the insertion / removal direction is performed. The guide frames 15 and 16 are respectively guided by a pair of guide grooves 19 and 19 formed in the rear half of the left and right side portions of the housing 3 and can slide in the insertion / removal direction with respect to the housing 3. Each guide groove 19 is provided with a stopper 20 located above the downstream portion of the slider 9 in the insertion direction and a lock portion 21 located below the portion of the slider 9 on the extraction side of the stopper 20. (In FIG. 1, the stopper 20 and the lock portion 21 are shown only in the guide groove 19 on the right side.) The lock portion 21 is for temporarily fixing the slider 9 to the housing 3.

Further, at the tips of the guide frames 15 and 16,
As shown in FIGS. 2 and 5, an inward hook 22 is formed which engages with the stopper 20 at the pushing position of the slider 9 and holds the pushing position. Next, referring to FIGS. 1 and 2A, the insertion protrusion 2 of the housing 3
Openings 24 are formed side by side on the front end face 2a of the above so as to face the respective contacts 5. The latter half of both sides of the housing 3 is made wider than the insertion protrusion 2, and the pair of guide grooves 19 are formed. In the upper plate portion 25 of the housing 3, at the push-in position of the slider 9, a step that matches the first holding frame 13 and the first convex portion 17, and the second holding frame 14 and the second convex portion 18, respectively. Recessed part 4
0 and 41 are formed.

The contact 5 serves as a fixed portion 5a having a U-shaped cross section, an elastic piece 5b serving as a connecting portion of the FPC 6 facing the bottom plate of the fixed portion 5a, and a connecting portion for a contact of a paired connector. The elastic piece portion 5c is provided. The front half of the housing space 4 of the housing 3 has a partition wall 27 that connects the upper plate 25 and the lower plate 26 of the housing 3.

It extends to the middle part in the height direction. These partition walls 31
The space between the lower plate portion 26 and the lower plate portion 26 is the slider insertion space 2 described above.
It is 9. In this embodiment, the end portion 7 of the FPC 6 is attached to the slider 9 in the state shown in FIG.
When the FPC 6 is set upside down on the placing portion 8 of the FPC 6 as shown in FIG.
The PC 6 is reliably prevented from being set in a normal state. At the stage of setting the FPC 6 in this way, the assembler can be made sure to recognize that the FPC 6 is facing down, and as a result, the FPC 6 can be reliably prevented from being erroneously inserted into the housing 3. be able to.

Further, since the anti-set preventing portion composed of the convex portions 17 and 18 and the concave portions 11 and 12 fulfills the function of preventing the FPC 6 from coming off the slider 9 when the FPC 6 is properly mounted, the coming-off preventing means. The structure can be simplified as compared with the case where is separately provided. Furthermore, the convex portion 1
Since the anti-set preventing portion composed of 7, 18 and the concave portions 11, 12 has a function of positioning the FPC 6 in the slider 9, the structure can be simplified as compared with the case where the positioning means is separately provided.

In the above embodiment, the widths of the first and second convex portions (similarly, the first and second concave portions) are made different, but the first and second convex portions (similarly). At least one of the shape, the position, and the size of the first and second recesses) may be different. Then, FIG. 6 and FIG.
Shows another embodiment of the present invention. With reference to these drawings, the present embodiment is different from the embodiment of FIG. 1 in that in the embodiment of FIG.
Although a part of 14 has advanced to the mounting plate 8 and comprised the convex parts 17 and 18, instead of this, in this Embodiment, it is independent from the holding frames 13 and 14 on the mounting plate 8. As the convex portion, for example, columnar first and second ribs 32 and 33 are formed. The diameter of the first rib 32 is larger than the diameter of the second rib 33. Correspondingly, the FPC 6 is provided with first and second rib insertion holes 34 and 35 as recesses that fit exactly into the first and second ribs 32 and 33, respectively. Further, the housing 3 is formed with recesses 36 and 37 that allow the ribs 32 and 33 to enter when the slider 9 is inserted. Also in the present embodiment, the same operational effects as those of the embodiment of FIG. 1 can be obtained.

Next, FIG. 8 shows still another embodiment of the present invention. The present embodiment differs from the embodiment of FIG. 6 in that a single convex portion is formed at a position offset by a predetermined distance d from the center position C of the mounting plate 8 of the slider 9 in the left-right direction, for example, a columnar shape. The rib 38 is formed, and the rib insertion hole 39 is formed as a single recess at the position of the FPC 6 corresponding to the rib 38. The housing 3 is also formed with a recess 42 that allows the rib 38 as a protrusion to enter when the slider 9 is inserted. Also in the present embodiment, when the FPC 6 is set face down, the rib 38 cannot fit into the rib insertion hole 39, so that the face setting is reliably prevented. It is possible to reliably prevent erroneous insertion of the FPC 6.

Besides, various modifications can be made within the scope of the present invention.
