Differential Signal Connector

Abstract

The invention discloses a differential signal connector. The differential signal connector comprises a plurality of terminal modules and a plastic body, wherein each terminal module comprises a terminal seat, a signal terminal and a ground terminal, the signal terminal and the ground terminal are integrally fixed with the terminal seat, a conductive polymer material layer further fixedly covers the end surface of the terminal seat and is conducted with all ground terminals to form a full-package shielding structure having a shielding function on the signal terminals, the plastic body is provided with a plurality of plug-in grooves, a plurality of first terminal holes and a plurality of second terminal holes, the plurality of first terminal holes and the plurality of second terminal holes pass through the plug-in grooves, the terminal modules are fixedly inserted to the plug-in grooves of the plastic body, and contact parts of the signal terminals and contact parts of the ground terminals of the terminal modules separately extend to the first terminal holes and the second terminal holes. Through the cooperation of the conductive polymer material layer and the ground terminals, the problems of signal interference, crosstalk and the like generated during high-speed transmission of the signal terminals are solved, all noise can be shielded in the outside, the high-speed signal transmission stability of the signal terminals is ensured, and the high-frequency performance of a product is relatively high.

Description

Technical field: [0001] The invention relates to the technical field of connector products, in particular to a differential signal connector. Background technique: [0002] Differential signal connectors are commonly used connectors for large-scale communication equipment, ultra-high-performance servers and supercomputers, industrial computers, and high-end storage devices. Due to the development of communication technology, signal transmission speeds are getting higher and higher, so it is necessary to solve problems such as interference and crosstalk that occur due to the distributed capacitance and inductance caused by the high-speed transmission of high-frequency signals. [0003] However, most of the current differential signal connectors are not equipped with a shielding device for anti-crosstalk, that is, the differential signal connector is relatively lacking in signal shielding technology, resulting in relatively large signal interference between the signal terminals in th...

AI Technical Summary

Problems solved by technology

[0003] However, most of the current differential signal connectors are not equipped with shielding devices for anti-crosstalk, that is, differential signal connectors are relatively deficient in signal shielding technology, resulting in relatively large signal interference between signal terminals in differential signal connectors. In turn, the high-frequency performance of the product is poor, causing great trouble to users
