Differential contact module, differential connector and differential pair shielding structure

Abstract

The invention relates to a differential contact module, a differential connector and a differential pair shielding structure. The differential pair shielding structure comprises two oppositely-bondedshielding sheets. The opposite sides of two shielding sheets are provided with accommodation slots for accommodating a differential signal pair. The corresponding accommodation slots on two shieldingsheets are buckled and assembled to form an accommodation hole for accommodating the differential signal pair to fully surround and shield the differential signal pair. The differential signal pair isintegrally located in the accommodation hole from a socket end to a plug end, and fully surrounded and shielded by two shielding sheets to ensure that any two adjacent differential pairs are completely isolated by the shielding sheets. An electromagnetic field between two signal conductors is effectively restrained. The leakage of magnetic field energy is reduced. Signal interference is reduced.The structure is relatively simple. At the same time, two shielding sheets are oppositely bonded, which is convenient for assembly and processing.

Description

technical field [0001] The invention relates to a differential contact module, a differential connector, and a differential pair shielding structure. Background technique [0002] Differential connectors are mainly used in occasions that require high-speed, high-quality transmission signals. Its main components include a housing and a differential contact module disposed in the housing. The differential contact module includes an insulator and a contact that is fixedly assembled on the insulator. The contacts include differential signal pairs and grounding shields. A differential connector often includes multiple differential contact modules. The differential contact modules are fixedly arranged side by side in corresponding slots of the shell layer by layer to realize the integration of each differential contact module. [0003] In the current differential connector, in order to reduce the electromagnetic interference between the differential pair signals of different diffe...
