plug connector

Abstract

A plug connector, which can be connected to a socket connector, the socket connector includes two elastic pieces, wherein the plug connector includes an insulating body, which is composed of a tongue and a step part to carry the connecting terminal; and a metal shell, It has a top surface, a bottom surface and two side walls. The two side walls are connected to the top surface and the bottom surface and are jointly surrounded to form a storage slot. The insulation system is housed in the storage slot and assembled with a metal shell. In one body, the top and bottom surfaces of the metal shell or the top or bottom surface are provided with multiple depressions, protrusions or a long depression for contact with the metal shrapnel of the socket connector; through the metal shell The structure punched on the top or bottom surface of the plug can prevent electromagnetic interference, dust and chips, and can maintain a stable insertion force after multiple insertions and extractions.

Description

technical field [0001] The present invention relates to a plug connector, in particular to a plug connector capable of preventing electromagnetic interference, dust-proof, chip-proof, and can maintain a stable plug-out force after repeated plug-in and pull-out. Background technique [0002] Universal Serial Bus (USB) connectors, generally known as USB connectors, have been widely used in signal transmission of various computer products due to their characteristics of plug and play and fast transmission speed. With the development of USB connectors, people have more requirements for transmission speed and stability. [0003] Currently, USB 2.0 is mostly used as the transmission interface in the market. With the continuous expansion of transmission files, USB 2.0 can no longer meet the needs of the market. USB3.0 has the feature of backward compatibility, and has both the ease of use and plug-and-play function of traditional USB technology. Therefore, the technical goal of th...

AI Technical Summary

Problems solved by technology

Obviously, at least two holes defined on the upper surface of the metal shell will lead to poor integrity of the metal shell. When the plug connector is connected to the socket connector, it will cause electromagnetic interference (Electromagnetic Interference) due to the lack of shielding. ; EMI) phenomenon will cause interference and instability when the transmission signal passes through the connector

In particular, the electromagnetic interference phenomenon caused by the lack of shielding will be more obvious at the higher frequency of USB3.0. This electromagnetic interference phenomenon caused by at least two penetration holes defined on the upper surface of the metal shell must be solved.

[0005] In addition, since there are at least two holes defined on the wall of the metal shell, dust and fines may fall into the metal shell from the gap between the insulating body and the penetration hole, resulting in poor contact of the connector or affecting the plugging and unplugging of the USB connector. force
