Abstract

The invention relates to a differential connector, a differential pair shielding structure thereof and a shielding buckle plate. The shielding buckle plate comprises a plate body. The plate body is provided with an avoiding hole for avoiding a differential signal pair, and further provided with a contact part for contact conduction with a shielding pin on the shielding sheet of each differential contact module. The plate surface of the plate body is provided with a bump in interference clamp fit with a clamp slot on a shielding sheet, or the plate surface of the plate body is provided with a clamp slot in interference clamp fit with a bump on a shielding sheet. The relative positions between the shielding buckle plate and a shielding sheet are fixed. The shielding stability of a full shielding structure is further ensured. At the same time, the connection form is convenient, and the overall structure is simple and easy to manufacture.

Description

technical field [0001] The invention relates to a differential connector, a differential pair shielding structure, and a shielding buckle plate. Background technique [0002] The differential connector in the prior art includes several signal terminals and grounding pins, wherein the signal terminals are arranged in the form of differential pairs, and the corresponding grounding pins are surrounded on the outside of the corresponding differential signal pairs, so as to realize the corresponding differential pair Provides electromagnetic shielding. [0003] As shown in the U.S. Patent Publication No. US2007155241A1, there are a plurality of L-shaped shielding sheets arranged in a matrix in the backplane connector, and each L-shaped shielding sheet is a shielding pin, and the differential signal surrounded by the L-shaped shielding sheets It has a shielding effect to reduce crosstalk, but each shielding pin is not connected to each other inside the backplane connector, so eac...
