The plug-in and disengagement prevention structure of the flexible circuit cable.

Background technique

Flexible flat cables or flexible flat cables are widely used in various electronic products such as notebook computers, personal digital assistants, and mobile phones. The traditional flexible cable structure is generally a structure in which several wires covered with an insulating layer are arranged side by side to form a row of wires, and is used for the transmission of electronic signals in conjunction with connectors or circuit welding.

Since the flexible circuit cable is thin and flexible, when the flexible circuit cable is plugged into a corresponding slot, the insertion is often inaccurate and the stability is insufficient. In response to this problem, practitioners combine a connector at the front end of the flexible circuit cable to enhance its structural stability and improve the electrical contact stability of the connector. The connector generally includes a metal part and a plastic part.

When assembling, first attach the metal part to the flexible circuit cable, then position the plastic part on the preset section of the flexible circuit cable, and then push the metal part forward to cover the plastic part . At this time, the insertion section of the flexible circuit cable can be plugged into the slot.

However, in the prior art, since there is no disengagement preventing structure, if the user pushes the metal part backwards, the connector will be separated from the plastic part along the extending direction of the cable. Since the plastic part lacks the sheathing and bonding of the metal part, the plastic part cannot be positioned in the predetermined section of the flexible circuit cable. In this way, the function of arranging metal parts and plastic parts is completely lost, and the originally expected purpose of enhancing the stability of the mechanism and improving the electrical contact stability of the plug-in connection cannot be achieved.
