High-speed backplane connector plug, differential electric connection part thereof and shielding module thereof

Abstract

The invention provides a shielding module of a high-speed backboard connector plug, which comprises a first shielding sheet, a second shielding sheet, and a wing part which is arranged at the middle part of a shielding group forming the first shielding sheet and the second shielding sheet and is higher than the surface where the middle part is located, and is used for isolating crosstalk between adjacent signal groups, in addition, a shielding connecting piece electrically connected with the first shielding piece and the second shielding piece is further arranged, the shielding connecting piece is located between the second side face of the first shielding piece and the second side face of the second shielding piece, and one side of the shielding connecting piece is electrically connected with the second side faces of all the shielding groups in the first shielding piece. And the other side of the shielding connecting piece is electrically connected with the second side surfaces of all the shielding groups in the second shielding piece, and the two sides of the shielding connecting piece are communicated. According to the shielding module, the common-ground interconnection of signal loops in the contact areas of the plug and the socket is realized, the resonance problem of crosstalk in transmission of the high-speed connector can be effectively suppressed, and the signal quality at the rate of 56Gbps or above is ensured.

Description

Technical field [0001] The present application relates to the technical field of communications devices, and particularly to a high-speed backplane connector plug and a portion which is electrically connected to the differential, the masking module. Background technique [0002] Connector for circuit is blocked at the barrier between the isolation circuit or bridge the communication gap between the circuit board so that current flows, the circuit to achieve a predetermined function. Since the switches, routers, modem (Modem), and other communication terminal apparatus user access terminal needs bandwidth increases, high-speed transmission signal integrity of the connector and the signal (signal integrity) demanding. In a high speed docking connector (Docking Connector), the differential signal with its good interference properties has been widely used. Common high-speed backplane connectors typically comprises a set of signals is provided on the insulating base spaced, group shie...

AI Technical Summary

Problems solved by technology

However, when the receptacle shielding sheet cooperates with the grounding contact inside the receptacle connector, it is easy to break the complete shielding reference above the signal terminal, affecting the return flow path, and a single convex hull cannot achieve multiple contact contacts at the convex hull, causing the plug to be grounded Contacts produce stub effect

Moreover, the complexity of the shielding structure is increased, and the requirements for assembly tolerances are stricter

[0006] Based on this, for the design of the shielding sheet, in the prior art, either because of the inconsistency of the processing technology, or the weak ability to control the resonance due to the fluctuation of the shielding sheet, or the poor interconnection effect of the shielding group contacts where the plug and socket are mated, cannot To control resonance, or to achieve common ground interconnection requires more complex shielding structure and more materials
