Reversible high-speed transmission connector

Abstract

The invention discloses a high-speed transmission connector which can be plugged in and out in reverse, comprising an upper terminal module, a lower terminal module, an upper fixing piece, a lower fixing piece and a shell. The upper terminal module has an integral structure, including a row of upper terminals, a grounding piece and an upper insulator covering the upper terminals and the grounding piece. The upper terminal module is stacked and fixed above the lower terminal module. The upper engaging portion of the upper fixing piece and the lower engaging portion of the lower fixing piece are respectively inserted from the top and bottom of the fixing groove of the upper insulator and pass through the corresponding through holes on the grounding piece, so that the upper engaging portion and the lower engaging portion The lower engagement parts engage with each other and are fastened in the through hole of the ground plate. In this way, not only can the upper terminal module and the lower terminal module be fixed, but also a complete grounding path or shielding path can be formed, thereby ensuring the safety and accuracy of signal transmission of the high-speed transmission connector.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a high-speed transmission connector that can be plugged in and out in reverse. Background technique [0002] The Universal Serial Bus (USB) connector is a serial bus standard that connects computer systems and external devices. It is also a technical specification for input and output interfaces. It is widely used in information communication products such as personal computers and mobile devices. And extended to photographic equipment, digital TV (set-top box), game consoles and other related fields. [0003] As we all know, it is a worldwide problem that the USB connector cannot be inserted correctly. The Type-C (Type-C) interface solves this problem. It supports double-sided insertion of the USB connector, and the design is thinner, which is conducive to the creation of ultra-thin mobile phones, and the transmission speed is also faster. [0004] However, the current rese...

AI Technical Summary

Problems solved by technology

[0004] However, the current research on this kind of high-speed transmission connector that can be plugged and unplugged is still very limited, and there are still many technical problems. For example, there will be an assembly process after the upper terminal module is injection molded and then assembled with the grounding piece separately. The problem of cumbersome and large tolerance; or the manufacturing process of the upper and lower terminal modules being injection molded separately and then injection molded together with the grounding piece is also quite complicated; the existing shell and insulator need to use auxiliary fixtures to achieve For the purpose of fixing, this kind of structural design still needs to be simplified; the existing upper and lower fixing pieces are fixed by laser welding, and this structural design makes the assembly process complicated; The contact is unstable and prone to poor contact
