Connector for flexible base board

Abstract

A connector for connecting to a flexible substrate which includes reinforcement for the surrounding areas of the pivot-supporting holes which support an operation lever and provides feedback to an operator when the operation lever is locked to the housing of the connector. A slider is directed by guides while the operation lever turns. When the slider is at a backward position, an insertion opening can be accessed for inserting a flexible substrate. When the slider is at a forward position, a press plate of the slider presses either one of the flexible substrate which has been inserted into the opening and the contacts provided in the housing to the other one. An electrical connection is established between the flexible substrate and the contacts. The operation lever is parallel to the slider in the forward position, and locks provided on a side surface opposite to the side surface with the insertion opening are locked to turn locks on the operation lever. The guides are fixed to the housing and are formed by bending a metal plate into a U shape. The pivot-supporting holes are formed individually on the guides.

Description

[0001] The technical field of the invention [0002] The present invention relates to a flexible substrate and a printed circuit board in which a plurality of contact terminals are exposed at the end of a flexible flat plate such as a flexible flat cable (hereinafter referred to as FFC) or a flexible printed circuit board (hereinafter referred to as FPC). Connectors for electrical connection. Background technique [0003] In the past, in order to connect flexible substrates such as FFC or FPC to printed circuit boards, connectors for connecting flexible substrates were fixed to the side of the printed circuit board to connect flexible substrates such as FFC or FPC to flexible substrates. connector connected. [0004] In addition, since FFC or FPC is flexible, it is generally possible to insert a flexible substrate such as FFC or FPC using a low insertion force that is not affected by the contact pressure from the contact of the connector for connection. At the same time, afte...

Problems solved by technology

[0020] However, in Conventional Example 1, in the pivot support hole 113 penetratingly provided on the box body 102, the pivot 112 protruding from the rotating arm portion 110 of the operating lever 104 is rotatably engaged, and the operating lever 104 is arranged to be rotatable. However, since the flexible substrate connection connector 101 itself is relatively small, the strength around the pivot support hole 113 is not strong enough, so once an operation error is applied and an overload force is applied, there will be damage around the pivot support hole 113. and the problem of damage to the flexible substrate connection connector 101

[0021] In addition, in Conventional Example 1, since the force required to pull out a flexible substrate such as FFC or FPC is not transmitted to the operating rod 104, the operating rod 104 will not rotate freely, but when the flexible substrate such as FFC or FPC is pulled, the operating rod 104 will not rotate freely. When the substrate 120 is mounted on the flexible substrate connection connector 101 so that the operation lever 104 is rotated and the contacts 105, 106 are in contact with the flexible substrate 120, whether the operation lever 104 is rotated in a reliable contact state Judgment is based on the feeling of the operator who turns the operating lever 104 to be parallel to the upper surface of the box body 102, and there is a problem that it cannot be judged reliably.

Then, when the operating lever 104 is rotated to bring the flexible substrate 120 into contact with the contacts 105, 106, there is a possibility that the operating lever 104 is slightly rotated in a direction to release the contact between the flexible substrate 120 and the contacts 105, 106 due to external force such as vibration. The connection state between points 105 and 106 and the flexible substrate 120 is not sufficient or there is a possibility of dissolving
