Abstract

The invention provides an LVDS connector with lock and unlock structure, which can connect a flexible flat cable and a printed circuit board, and includes a first component and a second component. The first component can be connected to a flexible cable. The second component can be connected to the printed circuit board. When the plug-in provided by the first component moves toward the action slot of the second component, the plug-in drives the pull rod of the second component to rotate in the first rotation direction until the plug-in locks the first component; and when the pull rod is driven by an external force, it moves opposite to the first component. When a rotation direction is a second rotation direction, the plug-in is pushed away by the pull rod, so that the first component is separated from the second component.
