Description

FPC connector

Technical Field

The utility model relates to a connector technical field, concretely relates to FPC connector.

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 flip cover, a terminal and a welding sheet, the structural design of the existing FPC connector is unreasonable, the flip cover is not compact in connection with the terminal, the flip cover is easy to open accidentally due to vibration, the reliability of a product is low, and the FPC connector also has the defects of inconvenience in assembly and complex structure.

Disclosure of Invention

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

In order to realize the above object, the utility model discloses a FPC connector, including gluing core, a plurality of interval arrangement setting terminal piece in gluing the core, rotating flip, two soldering lugs of setting respectively on the both ends of gluing the core of setting on gluing the core, terminal piece serve and be provided with support arm, contact arm respectively, the support arm on have the branching and be formed with first supporting part and second supporting part, first supporting part on be provided with the arc wall, and be formed with the centre gripping space between first supporting part and the second supporting part, flip on correspond centre gripping space department and be provided with pivot portion, centre gripping space lock just constitute the joint cooperation of flip and terminal piece in pivot portion.

The beneficial effect of above-mentioned structure is: be provided with first supporting part and second supporting part on the support arm of terminal piece, be formed with the centre gripping space that is used for centre gripping flip's pivot portion between first supporting part and the second supporting part, flip's pivot portion is difficult for breaking away from the centre gripping space, has guaranteed that flip and terminal piece are connected compacter, and flip's rotation is more smooth and easy, does not have the card to pause. Therefore, the FPC connector has the advantages of simple structure, compact structure, stable and reliable performance, reliable connection and convenient and fast assembly.

Particularly, one end of the soldering lug is provided with two insertion pieces, the rubber core is provided with slots matched with the insertion pieces corresponding to the insertion pieces, the insertion pieces are respectively inserted into the corresponding slots and form clamping matching of the soldering lug and the rubber core, and the other end of the soldering lug is bent towards the outer side of the rubber core, extends and wraps the side wall of the rubber core. The soldering lug is connected with the rubber core in a clamping matching mode, so that the soldering lug is convenient to assemble with the rubber core, and the soldering lug is wrapped on the side wall of the rubber core, so that the connection between the soldering lug and the rubber core is more compact, the soldering lug and a circuit board are more compact in welding, and the working reliability of the FPC connector is improved.

Particularly, each plug-in strip on all be provided with the anticreep barb, the spacing cooperation of anticreep barb block in the slot and constitution soldering lug and gluey core. The anti-falling barb can fuse with the rubber core mutually, has guaranteed that the soldering lug is compacter with being connected of rubber core.
