[0001] The utility model relates to the technical field of electronic connectors, and particularly refers to a Type-C connector assembly. Background Art

[0002] With the continuous progress of technology and the increasing demands of users, data transmission and charging methods have been greatly improved. The USB Type-C socket performs excellently in terms of transmission speed, compatibility, durability, charging speed, and safety, and has become one of the socket standards widely adopted in modern devices. As a standard socket, the USB Type-C socket adapts to the trend of smaller, thinner, and lighter form factors, as well as the characteristics of high-speed transmission, wide compatibility, durability and stability, fast charging, and safety and reliability, bringing users a convenient, efficient, and safe connection experience.

[0003] Currently, the internal main structure of the USB type-c socket is divided into upper row terminals and lower row terminals. After being injection molded separately, they are combined with the middle steel sheet through an automatic machine and then injection molded again. This structure is complex, with poor stability, and the production process is complex, resulting in an increase in production costs. Summary of the Utility Model

[0004] The purpose of the utility model is to address the deficiencies of the prior art and provide a Type-C connector assembly with a scientific and simple structure. By using insert molding for both the upper row terminals and the lower row terminals to form semi-finished products, and then combining and molding the upper layer injection plastic part and the lower layer injection plastic part, the overall structure of the connector is made more reliable, reducing the investment in the automatic machine combination process, saving processing costs, and improving the product yield.

[0009] Further, fixing pins for connecting to the PCB main board are provided on the middle steel sheet.

[0010] Further, a plurality of grooves are provided on the upper injection-molded plastic part, and a plurality of protrusions are provided on the lower injection-molded plastic part. The protrusions and the grooves are arranged in an up-and-down corresponding manner.

[0011] Further, both the upper row of terminals and the lower row of terminals are integrally stamped and formed structures.

[0012] Further, the upper row of terminals and the middle steel sheet are formed in the upper injection-molded plastic part by insert molding.

[0013] Further, the lower row of terminals is formed in the lower injection-molded plastic part by insert molding.

[0014] The above technical solutions have the following beneficial effects compared with the prior art:

[0015] A Type-C connector assembly of the present utility model includes an upper assembly and a lower assembly. The upper assembly includes an upper row of terminals, an upper injection-molded plastic part, and a middle steel sheet. The lower assembly includes a lower row of terminals and a lower injection-molded plastic part. By using insert molding (Insert Molding) for both the upper row of terminals and the lower row of terminals to form semi-finished products, and then combining and molding the upper injection-molded plastic part and the lower injection-molded plastic part, the overall structure of the connector is made more reliable, reducing the investment in the automatic machine combination process, saving processing costs, and improving the product yield.
