[0002] FPC connector, or flexible printed circuit board connector, is a drive circuit connector made of soft materials that can be folded and bent. FPC connectors are mainly composed of metal terminals, connectors and retainers. Metal terminals are the key components for connecting FPC with other electronic components. FPC connectors have the characteristics of excellent flexibility, flexible application, and foldability. They can also save labor costs and space, simplify wiring procedures, and make wiring simple.

[0003] The flip-free FPC connector is a special type of flexible printed circuit board connector, whose main feature is that it can be connected without flipping the cover. Figure 1 As shown, it uses plastic material as the main body, but plastic material cannot shield interference, and its outer end lacks a corresponding shielding structure, which easily causes external noise to interfere with the connector and affect the normal signal transmission quality of the FPC connector; the traditional flip-free FPC connector terminal is a blanking Pin insertion structure with a knife-edge contact surface, high surface roughness, and unstable contact signal.

[0004] Therefore, it is necessary to design an ultra-thin, high-frequency, high-speed, flip-free FPC connector to solve the above-mentioned problems. Utility Model Content

[0008] As a preferred solution of the utility model, the cover plate is made of metal material with shielding function by cutting and stamping forming process.

[0009] As a preferred solution of the utility model, the cover plate is completely wrapped around the upper outer end of the plastic body, and support blocks are integrally provided on the left and right sides of the cover plate.

[0010] As a preferred solution of the utility model, two elastic buckle blocks are respectively arranged on the left and right sides of the plastic body, and two buckle grooves are respectively opened on the left and right sides of the cover plate. The plastic body and the cover plate are clamped between the elastic buckle blocks and the buckle grooves.

[0011] As a preferred solution of the utility model, the bent end of the terminal adopts an embedded rubber-encapsulated structure, and the contact surface adopts a precision-rolled surface.

[0012] As a preferred solution of the present invention, the overall height of the connector body is 0.5-0.6 mm.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the present invention, the following purposes are achieved by improving the existing traditional flip-free FPC connector structure: 1. This solution can play a shielding function by adding a metal cover plate on the FPC connector, which can prevent some noise from interfering with the connector and improve the transmission quality; 2. Compared with the design of the traditional FPC connector, this solution can reduce the plastic material and reduce the harm of plastic to the environment; 3. This solution is a bent terminal embedded in a rubber-coated structure, the contact surface is a precision-rolled surface, the surface roughness is very small, the transmission signal is stable, the contact impedance is small, the contact is more reliable, the signal transmission is more stable, and high-frequency and high-speed transmission is easy to achieve; 4.
