Description

LVDS connector with lock and unlock structure

The present invention relates to a connector, and in particular, an LVDS connector having a clamp and an unlocking structure.

Conventional LVDS connectors require a relatively large operating space because they are unlocked by means of an unlocking device located at the end of the cable. Also, since it is located at the end of the cable, it is not possible to determine with certainty whether it is unlocked or still locked. This often leads to damage to the locking structure as the cable is pulled out without being fully unlocked.

Therefore, the present invention proposes an LVDS connector having a locking claw and an unlocking structure used to solve the disadvantages of the existing connector.

A first object of the present invention is to provide an LVDS connector having a locking and unlocking structure capable of connecting a flexible flat cable and a printed circuit board.

An LVDS connector with a catch and unlock structure has a first component and a second component. The first component can connect a flexible flat cable. The first component also has a first housing, a first rubber core, and a second housing. The first housing includes a first body, a leaf spring, and a plurality of insertion pins. The leaf spring is first formed on the surface of the main body to be in contact with the printed circuit board, and the insertion pins are first formed on both sides of the main body. The first rubber core includes a third body, a plurality of insertion holes and a plurality of insertion members. The third body is installed on the first body. The third body forms an insertion member, and an insertion hole is formed in each insertion member. The insertion hole is provided corresponding to the insertion pin. The second housing includes a second body and a plurality of covering members. The second housing and the first housing form a mounting space to mount the flexible flat cable. The second body fixes the first rubber core to the mounting space through the covering member. The second component can connect a printed circuit board. The second component can connect and separate the first component. The second component also includes a second rubber core, one fixing member, and a plurality of levers and terminals. The second rubber core includes a fourth body and a plurality of working grooves. The fourth body forms an action groove, and also forms a plurality of sockets in the action groove.
