Abstract

The invention belongs to the technical field of cables, and relates to a connector unit, a connector module and electronic equipment, the connector unit comprises a shielding sheet, a shielding shell assembly, a plurality of shielding covers and a plurality of differential pair signal terminals, the shielding shell assembly is arranged on the shielding sheet, the plurality of shielding covers are arranged on one side of the shielding sheet, the plurality of shielding covers are provided with openings, and the differential pair signal terminals are arranged in the openings. The opening directions of two adjacent shielding cases are respectively a positive direction and a negative direction, a differential pair signal terminal is arranged in each shielding case, and each differential pair signal terminal is respectively used for being electrically connected with each cable extending into the shielding case assembly. And the shielding shell assembly can effectively shield the cable extending into the shielding shell assembly. The opening directions of the two adjacent shielding covers are respectively the positive direction and the negative direction, so that the two adjacent shielding covers realize good isolation and blocking of the communication space between the two adjacent shielding covers, and the electromagnetic wave crosstalk between the differential pair signal terminals in the two adjacent shielding covers is better reduced; therefore, all-directional shielding of the differential pair signal terminals is realized.

Description

technical field [0001] The present application belongs to the technical field of cables, and in particular, relates to a connector unit, a connector module and an electronic device. Background technique [0002] Each working module of an electronic device usually needs to be connected to the backplane of the electronic device by a connector module composed of a plurality of connector units. The connector unit usually includes a plurality of independent connection units, and each connection unit has a differential pair signal terminal group for connecting cables and a shielding case surrounding the differential pair signal terminals. [0003] In the prior art, since the shielding cover needs to be designed to avoid encroaching on the space where the differential pair signal terminal group is inserted and matched with the external equipment, the shielding cover cannot completely cover the peripheral side of the differential pair signal terminal group, and it is necessary to T...
