Connector

Abstract

A connector to be surface mounted on a wiring board has a base having an opening to be inserted with a tip portion of a flexible printed circuit board at a front surface, and having a plurality of insertion holes passing from the front surface to a rear surface juxtaposed at a predetermined pitch, a connection terminal arranged in a projecting manner with a substantially T-shaped operating piece having at one end a movable contacting point that comes into pressure contact with joints juxtaposed at the tip portion of the flexible printed circuit board, the connection terminal having one end that becomes a fixed contacting point inserted to the insertion hole from the rear surface side, and an operating lever in which a cam portion is fitted into a turning recessed portion arranged at an upper side of the connection terminal to act as a turning supporting point, the cam portion driving an operation receiving portion positioned at the other end of the operating piece. A position regulation contacting portion that contacts a position regulating portion arranged at the upper side of the connection terminal when the operating lever is turned and a locking operation is completed is arranged at a lower surface of the operating lever.

Description

technical field [0001] The present invention relates to a connector, and more particularly, to a connector connected to a connection portion provided at a front end portion of a flexible printed circuit board. Background technique [0002] Conventionally, as a connector, for example, there is a connector for a printed wiring board in which a plurality of contacts are arranged in parallel and a plurality of terminals such as FPC are collectively connected. Furthermore, a case is provided which has an insertion groove into which the FPC or the like is inserted, the contact is arranged so as to protrude and recede freely from the insertion groove, and the operation member is provided so as to be movable between a connection position and a release position. Therefore, when the operation member is at the connection position, the contact is pressed by the operation member to protrude toward the insertion groove and is crimped on the terminal of the FPC or the like to be connected ...

AI Technical Summary

Problems solved by technology

[0004] However, in the above-mentioned connector, as in Patent Document 1 image 3 As shown in FIG. 4 , when the operation member 20, that is, the operation lever, is locked, the rotation operation will cause excessive rotation.

Therefore, the operating rod is lifted due to the principle of leverage, and it is easy to fall off from the housing, that is, the base

[0005] In addition, when the operation lever comes off, an excessive load acts on the contact point, that is, the connecting terminal, so that the connecting terminal is plastically deformed and there is a problem that connection cannot be performed.
