Embodiment Construction

[0020] Example 1 of the differential module, as figure 1 As shown, the differential module includes an insulator 11, a differential pair 12 and a ground pin. 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.

[0021] 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 corresponding shielding plate are fixed together so that the two are electrically connected to each other. Together, the end shields 14 can isolate the differential pair 12 of the differential module from the differential pair on an adjacent differential module, thereby avoiding electromagnetic interference between the two.

Abstract

The invention relates to the field of an electric connector and especially relates to a difference module and a full-shielding-type difference connector using the module. The difference module comprises an insulator, differential pairs and grounding pins. At least one side of the insulator is provided with a wiring shielding member; at least one side of each differential pair is provided with an end shielding member; and the end portion shielding members are in electrical connection with the wiring shielding member. At least one side of each differential pair of the difference module is provided with the end shielding member, and the end shielding members are in electrical connection with the wiring shielding member of the difference module, so that in the using process, when two difference modules coexist, the end shielding members block between the differential pairs of the two difference modules; electromagnetic interference between 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 differential module and a fully shielded differential connector using the module. 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...
