Abstract

The present invention provides an ultra-thin simple locking and unlocking connector that can connect a printed circuit board and a flexible flat cable. This ultra-thin quick lock and unlock connector has one terminal, one cover, one base, one insulator and multiple locking elements. The terminal can connect the printed circuit board and the flexible flat cable. The cover is combined with the base to form a mounting space that can accommodate the flexible flat cable. The base forms a hole to accommodate the deformation that occurs at the free end of the terminal after the terminal connects the flexible flat cable. The insulator forms a plurality of gaps and a plurality of grooves. A locking element is installed in this gap. The acting part of the locking element connects the hook part of the locking element, and when the acting part is pressed by the stressing part, the hook induces the movement of the hook part to unlock the flexible flat cable. Conversely, when the acting part is not pressed by the stressing part, the hook part allows the flexible flat cable to be snapped into the mounting space.

Description

ULTRA-THIN EASY-LOCK AND EASY-UNLOCK CONNECTOR

The present invention relates to a connector, and in particular, provides an ultra-thin simple locking and unlocking connector.
