Abstract

The invention provides a signal connector and relates to the field of data transmission. The signal connector includes a backplane connection portion and a daughter card connection unit. The backplaneconnection portion is provided with a first signal terminal pair and a first shielding sheet, and the daughter card connection unit is provided with a second signal terminal pair and a second shielding sheet. When the backplane connecting portion and the daughter card connecting unit cooperate with each other, the first signal terminal pair and the second signal terminal pair are joined one by one, and the first shielding sheet and the second shielding sheet can form a shielding cavity which coats the first signal terminal pair and the second signal terminal. Through the signal connector provided by the invention, the better shielding structure can be formed between transmission signals, the signal crosstalk can be reduced, and the signal integrity can be improved.

Description

technical field [0001] The present application relates to the technical field of data transmission, and more specifically, to a signal connector used in a data transmission system. Background technique [0002] In current communication systems, an interconnection system based on a combination of a printed circuit board (printed circuit board, PCB) and a daughter card is the most common interconnection architecture. As a connection bridge between the backplane and the daughter card, the signal connector is a key component that affects signal transmission. As the signal transmission rate continues to increase, higher requirements are placed on the integrity of the transmitted signal, and a key factor affecting signal integrity is the shielding structure in the signal connector. The currently used shielding structure is only a metal shielding sheet, which cannot achieve a good shielding effect. Therefore, a connector with a good shielding effect is needed to reduce signal cros...
