electrical connector

Abstract

An electric connector comprises the components of a terminal base which is provided with a base part and a tongue plate that frontwards extends from the base part, the tongue plate is provided with a first surface, a second surface which faces the first surface, a front end surface which is connected between the first surface and the second surface, and two side parts, and each side part is provided with a locking trough at a position which is next to the front end surface; a plurality of conductive terminals which are provided with contact parts that extend to the tongue plate, and the contact parts in two rows are exposed to outside from the first surface and the second surface of the tongue plate; and a metal shielding plate, wherein the metal shielding plate is provided with a body part which is arranged in the tongue plate and is arranged between the two rows of contact parts, frontwards projected parts which frontwards project from two sides of the front part of the body part to the front end surface, and locking projections which outwards project from two sides of the front part of the body part; the locking projections are arranged between the locking troughs and the front end surface; and the parts, which are adjacent with the frontwards projected parts, of the locking projections are embedded into the tongue plate and are not exposed to outside.

Description

technical field [0001] The invention relates to an electrical connector, in particular to an electrical connector which can improve the durability after multiple insertions and extractions. Background technique [0002] As a new generation product of USB 3.0 connector, the USB Type-C connector not only no longer has a directional plug interface, that is, the plug connector can be inserted into the socket connector in both directions, but also supports a data transmission speed of 10Gbit / s . The USB Type-C connector includes a plastic base and two rows of conductive terminals arranged on the plastic base. The conductive terminals include ground terminals and differential signal terminals adjacent to the ground terminals for high-speed transmission and data reception. There is a grounding metal sheet at intervals between the two rows of conductive terminals. The grounding metal sheet bears the back and forth insertion force of the connector, and the thickness of the groundin...

AI Technical Summary

Problems solved by technology

There is a grounding metal sheet at intervals between the two rows of conductive terminals. The grounding metal sheet bears the back and forth insertion force of the connector, and the thickness of the grounding metal sheet is usually thin. The contact pressure per unit area is relatively large, and the interface is rough, which is easy to cause wear.
