Description

Type-C connector assembly structure

This creation is about an electrical connector, especially an assembly structure of a Type-C connector.

In recent years, a new generation of USB 3.1 specifications has been developed in the electrical connector market, and among them, the USB 3.1 Type-C specification capable of supporting a transmission rate of 10 Gbps is most attracting attention of users. The new specification of USB Type-C, its biggest feature is that its upper and lower ends are completely consistent and there is no directionality in use, which provides users with faster transmission rate when transmitting large-capacity files, thus effectively shortening the transmission. time.

Furthermore, the connection terminal and the insulating seat of the conventional connector may be combined by injection molding or by plug-and-assembly. However, when the combination of injection molding is adopted, since the cost of the mold required for injection molding is high, it is not required for cost. Moreover, when the plug-in assembly method is adopted, since the upper and lower rows of the lead terminals of the Type-C connector are simultaneously present and the gap between the terminals is small, it is difficult to assemble, and a large error is likely to occur after assembly, thereby affecting Finished product yield.
