Abstract

This invention makes it a subject to provide a flexible board connector.

The flexible board is inserted into the main body of the connector to make electrical contact with the contact projections of the contact arms of the first and second terminals, and is highly stable and stable due to the pressing positioning of the interlocking block in the lower surface of the movable cover and its respective hole. Has the effect of not falling out. In addition, the movable cover is rotated outward to open the flexible substrate, and when the movable cover is rotated in the opposite direction, the contact protrusions of the respective rectangular linkage arms are driven to make electrical contact with the flexible substrate, and the movable cover is returned to its original position. Upon return, each interlock block presses the flexible substrate to make electrical contact with the contacting projections of the second terminal contact arm, whereby the contacting projections of the flexible substrate and the first and second terminals have stable electrical contact.

Description

Flexible board connector {Flexible board connector}

The present invention relates to a kind of flexible board connector, in particular, the electrical contact effect is good, at the same time, the flexible board is not easily pulled out, has a good practicality of fitting tightness with the connector, good positioning effect that the movable cover does not shake It relates to a flexible board connector having a.

The well-known flexible board connector has the following faults, as shown to FIG. 1 and FIG.

1. The terminal 8 inserted into the main body 7 of the connector is slightly fixed in the fitting groove 71 by the contact arm 81 and the support arm 82, and the inside abutment portion on both sides of the terminal 8 is provided. Since 831 and 832 abut on the edges 711 and 712 of both end portions of the fitting groove 71, the joint firmness of the terminal 8 and the fitting groove 71 is relatively low.
