Differential contact module and differential connector and connector assembly using the module

Abstract

The invention relates to the field of electrical connectors and particularly relates to a difference contact module and a difference connector and a connector assembly using the module. The difference contact module comprises an insulating base body, a differential pair and a grounding contact, wherein the differential pair and the grounding contact are assembled inside the insulating base body, a shielding plate is arranged above and / or below the differential pair and the grounding contact on the insulating base body, and at least one of the grounding contact and the shielding plate is provided with a protruding structure which protrudes towards the other one of the grounding contact and the shielding plate. During usage, a gap between two adjacent differential pairs, in which the crosstalk occurs, is greatly reduced, so that the crosstalk between two adjacent differential pairs of the difference connector can be reduced, and the signal transmission quality of the difference connector can be improved; besides, the shielding plate is arranged, so that two adjacent layers of difference contact modules of the difference connector are isolated, and the problem of the crosstalk between two adjacent layers of contact modules can be solved.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a differential contact module, a differential connector and a connector assembly using the module. Background technique [0002] Differential connectors use signal contacts to achieve signal connections between electronic devices. Usually, the distance between two adjacent signal contacts is limited, which leads to a mixed electric field that makes one signal contact between two adjacent signal contacts. Crosstalk occurs when the pins induce electrical interference, ultimately compromising signal integrity. [0003] The Chinese patent application number 2007100779307 discloses a high-speed, high-density electrical connector with a central shielding pin. The high-speed, high-density electrical connector with a central shielding pin includes an insulating base and is sequentially arranged on the More than two layers of contact modules in the insulating base, each of the contac...

AI Technical Summary

Problems solved by technology

The high-speed, high-density electrical connector with a central shielding pin is provided with the ground contact between two adjacent differential pairs of its contact module, thereby avoiding crosstalk between differential pairs, to a certain extent The reliability of signal transmission is improved, but the problem of crosstalk between the two differential pairs through the gap between the ground contact and the upper ground contact still exists, which limits the quality of signal transmission and cannot meet the requirements of some occasions. In addition, since there is no shielding structure between adjacent two-layer contact modules, the crosstalk problem between adjacent two-layer contact modules still cannot be solved
