Embodiment Construction

[0017] Examples of fully shielded differential connectors, such as Figure 1-6 As shown, the differential connector includes a housing 101 , a shield 102 and a differential module 103 .

[0018] The housing 101 is provided with mounting slots corresponding to the differential modules 103 one-to-one, and the shield 102 is a metal cover for cooperating with the housing 101 to fix the differential module 103 .

[0019] The differential module 103 includes an insulator 11 , a differential pair 12 and a ground pin 15 . The insulator 11 plays the role of combining the differential pair 12 and the ground pin, and the two sides of the insulator are respectively provided with a wiring shield 13. In this embodiment, the wiring shield 13 is a shielding plate, which is fixedly assembled on the insulator 11.

[0020] One side of the differential pair 12 is provided with an end shield 14. In this embodiment, the end shield 14 is a shielding sheet, and the shielding sheet and the correspon...

Abstract

The invention relates to the field of an electric connector and especially relates to a full-shielding-type difference connector. The full-shielding-type difference connector comprises a housing and more than two difference modules. Each difference module comprises an insulator, differential pairs and grounding pins. The housing is provided with plugging holes corresponding to the differential pairs and the grounding pins; at least one side of the insulator is provided with a wiring shielding member; the wiring shielding member is arranged between any two difference modules; at least one side of the plug section of each differential pair is provided with an end shielding member; the end portion shielding member is arranged between the corresponding differential pairs of any two difference modules; the end portion shielding members are electrically connected with the corresponding wiring shielding members; the housing is provided with openings corresponding to the end portion shielding members; and the openings and the plug holes are mutually isolated. In the using process, the end portion shielding members block between the plug sections of the differential pairs of the two adjacent difference modules, so that electromagnetic interference between the plug sections of the differential pairs of the two difference modules can be prevented, and furthermore, the problem that an existing difference connector damages signal integrity of a transmission line is solved.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a fully shielded differential connector. Background technique [0002] Differential connectors are mainly used in occasions that require high-speed, high-quality transmission signals. Its main components include housing, differential module and shield. The differential module includes an insulator and a contact piece fixedly assembled on the insulator, and the contact piece includes a differential pair and a ground pin. A differential connector often includes a plurality of differential modules, and the housing is provided with slots corresponding to the differential modules and socket holes corresponding to the plug-in sections of the contacts of the differential modules, and the differential modules are fixed and inserted layer by layer. In the corresponding slot on the shell, the plug-in section of the contact piece extends into the corresponding plug-in hole. [0003] ...
