[0002] In December 2013, the USB 3.0 promotion team released the rendering of the next generation USB Type-C connector, and then in August 2014, it was ready for mass production. The highlights of the new version of the interface are a slimmer design, faster transmission speed (up to 10Gbps) and more powerful power transmission (up to 100W). The biggest feature of the Type-C double-sided pluggable interface is that it supports double-sided insertion of the USB interface, officially solving the global problem of "USB can never be plugged in correctly", and it can be plugged in from the front or back.

[0003] The current female socket modules of USB Type-C connectors all include an insulating body and a hook member, an upper row of terminals and a lower row of terminals arranged on the insulating body. In order to fix the hook member, the upper row of terminals and the lower row of terminals together, the current traditional method adopts multiple molding and assembly methods, which makes the insulating body structure complex, the production efficiency is low, the product cost is increased, and the product quality is difficult to guarantee. Therefore, it is necessary to improve the current female socket module. Summary of the invention

The hook component includes a second material strip and a hook that are integrally connected, and the second material strip is overlapped and fixed together with the first material strip. The hook, the upper row of terminals and the lower row of terminals are all injection molded at the same time and fixed on the insulating body.

[0008] As a preferred solution, the second material strip is overlapped and fixed with the first material strip by one-time stamping of a metal mold, welding or post-process mechanical fixing.

[0009] As a preferred solution, a first fixing hole is formed on the first material strip, and a second fixing hole is formed on the second material strip, and the second fixing hole is directly connected to the first fixing hole.

[0010] As a preferred solution, there are two hook members arranged on the left and right, wherein the second material strip of one hook member is overlapped and fixed on one end surface of the first material strip, and the second material strip of the other hook member is overlapped and fixed on the bottom surface of the other end of the first material strip.

[0011] As a preferred solution, the hook is provided with a through hole for positioning the hook and the plastic during molding.

[0012] A method for manufacturing a USB Type-C female socket module by one-time injection molding comprises the following steps:

[0013] (1) Stamping out an integrated terminal assembly and hook piece;

[0014] (2) Fix the integrated terminal assembly and the hook member relatively together through the material strip;
