The contact of the mating connector protrudes from the external opening into the shielding cavity 21 and contacts the differential pair 41.

[0048] The shielding cavity 21 is provided with an insulating isolation shell 30. The isolation shell 30 is provided with isolation holes for avoiding the differential pair 41 insertion end, so that the differential pair 41 is insulated and separated from the conductive shell 20 through the isolation shell 30.

[0057] The end face of the external contact end 22 of the conductive shell 20 constitutes the end face of the insertion end of the female connector 100, and when the male connector 200 is inserted into the female connector 100, the side face of the part where the external contact end 22 of the conductive shell 20 is located is in contact with the inner side face of the frame-shaped ground frame of the male connector 200, so that the shielding conduction is ensured and the matching structure is simplified, and the shielding conduction of the male connector 200 and the female connector 100 is not affected by the position degree of the shielding part of the male connector 200. In other embodiments, the conductive shell can not be inserted into the male shell, and at this time, the male shielding part can be provided in a mesh structure, each pair of male signal pins corresponds to a mesh hole, the male shielding part is in contact with each male ground part, and after the male connector and the female connector are inserted, the end face of the conductive shell of the female connector is pressed onto the male shielding part to form shielding conduction.

[0058] After the male connector and the female connector are inserted, the conductive shell of the female connector that plays a shielding role cooperates with the shielding structure of the male connector to realize full-enclosure shielding of the insertion end link, improve crosstalk, and meet the demand of high-speed signal transmission.
