AI Technical Summary

Technical Problem

The existing Type C connectors require more than 2 moldings, with large manufacturing cycles and investment costs, high costs, and metal terminals are prone to shifting during molding, resulting in poor contact.

Method used

A single-formed Type C connector female seat structure is designed. By setting a socket at the end of the plastic terminal assembly, the end of the metal terminal PIN is buried in the plastic body, and folded 180° directly below the two outermost terminals to form a plug-in and pull-out lock PIN, and the plastic body is used to penetrate the through port to increase the contact area between the metal terminal and the plastic body.

Benefits of technology

The front and back sides of the male plug can be connected to the male plug in one molding, and the joint strength with the male plug is high, which reduces production costs and improves the service life of the mother seat and the stability of the conduction state.

Abstract

The present invention discloses a one-time molded Type C connector female seat structure, which includes a PCB connection board, an iron shell plugged into the PCB connection board, and a plastic terminal assembly wrapped in the iron shell, wherein the plastic terminal assembly includes a metal terminal and a plastic body integrally formed with the metal terminal by injection molding, wherein the metal terminal is divided into two groups and the connection part with the male plug is exposed on the upper and lower surfaces or both sides of the plastic body, and a plug-in locking PIN integrally connected with the PIN and folded 180° is arranged directly below the two outermost PINs of the metal terminal; the end bends of the PIN located on the upper and lower surfaces of the metal terminal are provided with a pressing part pressed by the plastic body. The present invention can realize the front and back plugging of the male plug with only one molding, and has high plug-in bite strength with the male plug, and low manufacturing cost.
