Background

A Flexible Printed Circuit Board (FPC) is a Printed Circuit Board made of a Flexible insulating base material (mainly, polyimide or a polyester film), and has many advantages that a rigid Printed Circuit Board does not have. For example, it can be freely bent, rolled, folded. The FPC can be used for greatly reducing the volume of electronic products, and is suitable for the development of the electronic products in the directions of high density, miniaturization and high reliability. Therefore, the FPC is widely applied to the fields or products of aerospace, military, mobile communication, laptop computers, computer peripherals, PDAs, digital cameras and the like. The interface component for connecting the flexible circuit board is a flexible circuit board connector, commonly known as an FPC connector. The FPC connector comprises a rubber core, a turnover cover, a terminal piece and a welding piece, the structural design of the terminal piece of the existing FPC connector is unreasonable, and a contact point of the terminal piece cannot be contacted with the middle part of a golden finger of a flexible circuit board, so that the contact between the terminal piece and the flexible circuit board is unreliable, and the FPC connector also has the defects of complex structure, unreliable performance, unreliable connection and inconvenient assembly.

Disclosure of Invention

An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance are reliable, connect reliable, assemble convenient high reliable FPC connector.

In order to realize the above-mentioned purpose, the utility model discloses a highly reliable FPC connector, including gluing core, a plurality of interval arrangements set up terminal piece in gluing the core, rotate flip, two soldering lugs of setting respectively on gluing the both ends of core on gluing the core, one of terminal piece serve and be provided with extension support arm, contact arm in gluing the core respectively, the other end of terminal piece on be provided with the weld part of extension outside gluing the core, the contact arm on be provided with two contact points respectively, and one side of two contact points is provided with the die-casting groove respectively, the terminal piece on one side department that corresponds the contact arm be provided with the arc wall.

The beneficial effect of above-mentioned structure is: the pressure casting groove is arranged on the contact point of the contact arm, so that the contact point can be ensured to be contacted with the middle part of the golden finger of the flexible circuit board, the contact reliability of the terminal piece and the flexible circuit board is favorably improved, the arc-shaped groove is arranged on the terminal piece, the elasticity of the contact arm is favorably improved, the contact of the terminal piece and the flexible circuit board can be ensured, and the FPC connector has the advantages of simple structure, stable and reliable performance, reliable connection and convenient and fast assembly.

Particularly, the support arm of the terminal piece is provided with an anti-falling barb which is inserted in the rubber core and forms the limit matching of the terminal piece and the rubber core. The anti-falling barb can avoid the terminal sheet from loosening and falling off, thereby being beneficial to improving the working reliability of the FPC connector.

Particularly, an arc-shaped clamping groove is formed in the soldering lug corresponding to the rotating shaft of the turnover cover, the rotating shaft of the turnover cover is clamped in the arc-shaped clamping groove and forms rotating connection and matching of the turnover cover and the soldering lug, and one end of the soldering lug is provided with an inserting part extending out of the rubber core. The arc-shaped clamping groove matched with the turnover cover is formed in the soldering lug, so that the turnover cover and the soldering lug can be assembled conveniently, and the assembly efficiency of the FPC connector can be improved.

In particular, a guide bevel is arranged on each side of the plug-in part. The guide inclined plane can play a guide role, so that the insertion part can be smoothly inserted into the insertion hole of the circuit board, and the insertion part can be welded in the insertion hole, thereby ensuring that the soldering lug is more firmly connected with the circuit board.
