Abstract

The present application relates to a backplane connector and belongs to the technical field of connectors. The backplane connector includes a base board; differential signal pins arranged on the baseboard, every two differential signal pins forming a group of differential pairs; a shielding system disposed on the base board and surrounding the differential pairs. The shielding system includes atleast one shielding unit, each of which includes at least one U-shaped shielding piece having the same opening direction, a sealing shielding piece and a ground metal connection piece, wherein the sealing shielding piece is arranged on the opening side of the last U-shaped shielding piece along the opening direction; the respective U-shaped shielding pieces surround a group of differential pairs from three sides; the last group of differential pairs along the opening direction is surrounded by the U-shaped shielding piece and the sealing shielding piece from four sides; one end of the ground metal connection piece is grounded, and the other end of the ground metal connection piece is in contact with the respective U-shaped shielding pieces and the sealing shielding piece arranged in the first direction in the same shielding unit, or the other end of the ground metal connection piece is in contact with the respective U-shaped shielding pieces and the sealing shielding pieces arranged inthe second direction in different shielding units.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to backplane connectors. Background technique [0002] Backplane connectors are used to transmit high-speed signals, so it is necessary to effectively reduce crosstalk between differential signals to the greatest extent. Usually, backplane connectors include multiple differential pairs and multiple shields, where a differential pair consists of two differential signal pins. The shield surrounds the corresponding differential pair, thereby providing electromagnetic shielding for the corresponding differential pair. [0003] In the related art, the shielding element is surrounded by two sides or three sides, and at least one side is open to electromagnetic interference, so that the shielding performance is poor and the effect is not good. Contents of the invention [0004] In view of this, the present invention provides a backplane connector in order to overcome the problems in ...
