Next, an embodiment of the present invention will be described in detail with reference to FIGS.

FIG. 1 is a perspective view showing a configuration of a connector 10 of the present invention, FIG. 2 is a perspective view showing a method of press-fitting a contact, and FIG. FIG. 3 is a plan view showing a substrate 30.

As shown in FIG. 1, a flexible board connector according to the present invention
Are provided so that when the lever 11 rotates, the recesses 15 provided inside the both side wall portions 14 of the housing 13 are fitted. Furthermore, housing 1
Another concave portion 17 is provided outside the side wall portions 14 at both ends of the clamp lever 3 so that the shaft portions 19 at both ends of the clamp lever 18 are fitted when the clamp lever 18 rotates. Also, as shown in FIG.
A plurality of contacts 40 are press-fitted from behind, the contact portion 41 of the contact 40 is seen in the mounting portion 16 of the housing 13, and the lever 11 and the clamp lever 18 are rotatably mounted above the housing 13. I have.
Further, as shown in FIG. 3, the flexible substrate 30 is provided with a number of pad portions 31 for making electrical contact with the contact portions 41 of the contacts 40.

Next, the operation of the embodiment of the connector for a flexible substrate of the present invention will be described in detail with reference to FIGS.

FIG. 4 is a front view for explaining the operation of mounting the FPC in the embodiment of the connector for a flexible substrate according to the present invention. (A) is a front view showing a state before mounting, (B) a state during mounting, and (C) a state after mounting.
In FIG. 4, the FPC is omitted for convenience of explanation. First, the FPC 30 is mounted by temporarily mounting the FPC 30 on the mounting portion 16 of the housing 13 from the direction of arrow A shown in FIG. 1 and the front direction of FIG. 4A, and then rotating the lever 11 in the direction of arrow B. Convex portions 12 on both side surfaces of lever 11
The recesses 15 inside the side walls 14 of both ends of the housing 13 are fitted to each other, and the state shown in FIG. Next, the clamp lever 18 is rotated in the direction of arrow C shown in FIG. 1 to fit the shaft portions 19 at both ends of the clamp lever 18 with the other concave portions 17 outside the side wall portions 14 at both ends of the housing 13. Then, the state shown in FIG. 4C is reached, and a series of operations is completed.
Although the clamp lever 18 is useful, it is not an essential component in mounting the FPC, but is used in accordance with the usage environment of the connector in the apparatus. Depending on the environment, even if the clamp lever 18 is not mounted, the original mounting of the FPC is not affected.

[0020]

As described above, according to the present invention,
After temporarily mounting the FPC on the mounting portion, the FPC is mounted by rotating the lever to fit the convex portions on both side surfaces of the lever with the concave portions inside the side wall portions of both ends of the housing, and further rotate the clamp lever. By moving the clamp levers, the shafts at both ends of the clamp lever are fitted into the recesses outside the side wall portions at both ends, thereby suppressing the elastic deformation of the side wall portions. Can be strengthened. As a result, a load is applied to the FPC in a direction in which the lever is lifted upward, so that even when a load that is turned on the lever in a direction opposite to the mounting direction of the FPC is applied, the lever can be prevented from coming off. .
