Description

Technical Field

It is most suitable for data transmission cables between mobile parts and motherboards, between PCB boards and in miniaturized electrical equipment, and is widely used in electric vehicles.

[0003] Flexible flat cables or flexible circuit boards serve as bridges between different components, and generally require electrical connectors to connect the ends. In actual application scenarios, miniaturization and ultra-thinness are the development trends of many electronic products, and therefore the volume requirements for electrical connectors are becoming increasingly stringent.

[0004] The patent closest to the prior art is publication number: CN204680836U, which discloses a board-end connector, including a board-end connector body, contact terminals, a flip cover and a grounding plate; the contact terminals are inserted into the board-end connector body, and the flip cover is arranged on one end of the board-end connector body; there are two grounding plates, which are arranged on both sides of the other end of the board-end connector body. The utility model has a simple structure. After the FPC line is connected to the board-end connector, the flip cover on the board-end connector presses the FPC line to improve the contact force fixation between the board-end connector and the FPC, solving the problem of easy separation and poor contact between the FPC line and the board-end connector. The grounding plate on the board-end connector is then welded and fixed to the PCB board as an integrated structure, which increases the holding force between the board-end connector and the PCB board and improves the stability between the board-end connector and the PCB board.

[0005] When the board-end connector body and the board-end connector are mated, the product is still prone to separation due to vibration due to insufficient holding force, so it is important to improve the holding force of the connectors after mating.

[0006] In view of this, the utility model proposes a buckle mechanism for a flat cable, which increases the retention force between the cable end connector and the board end connector through a buckle device to solve the problem that the connectors are easily separated when mated.
