Embodiment Construction

[0054] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0055] Specific embodiments of the contact module of the present invention, such as Figure 1 to Figure 9 As shown, the contact module includes an insulator 1, a ground contact 2 disposed in the insulator 1, and a differential pair 3. The differential pair 3 and the ground contact 2 are arranged side by side. Each differential pair 3 includes two signal contacts 31. The differential Two grounding contacts 2 are provided on both sides of the pair 3 to ensure the shielding effect on the differential pair 3 . Wherein the ground contact 2 and the signal contact 31 are bent contacts, and the differential pair 3 and the ground contact 2 are plastic-sealed in the insulator 1 .

[0056] like Image 6 and Figure 7 As shown, the contact module also includes a shielding plate assembly 4 arranged on the side of the insulator 1 for facing the adjacent contact mod...

Abstract

The invention relates to a shielding plate assembly, a contact module, and a high-speed electrical connector. The contact module includes an insulator, a ground contact, a signal contact, and a shielding plate assembly. The shielding plate assembly includes a contact shielding plate and an auxiliary shielding plate. The auxiliary shielding plate is in conductive contact with the contact shielding plate; The hole of the shielding plate on the body, the edge of the hole of the shielding plate has a contact piece protruding towards the side of the auxiliary shielding plate, the contact piece and the shielding body are integrally bent and formed, and the insulator is provided with an avoidance channel for the contact piece to pass through. The sheet is in conductive contact with the grounding contact piece, the auxiliary shielding plate is provided with a contact sheet perforation for the contact sheet to pass through, and the auxiliary shielding plate has a cover part for sealing the hole of the shielding plate. The auxiliary shielding plate covers the shielding plate hole on the contacting shielding plate, improves the anti-signal crosstalk ability of the ground contact, and solves the problem of poor anti-signal crosstalk ability of the current contact module.

Description

technical field [0001] The invention relates to a shielding plate assembly, a contact module, and a high-speed electrical connector. Background technique [0002] High-speed electrical connectors are mainly used in occasions that require high-speed, high-quality transmission signals, and their main components include housings, contact modules and shields that are laminated and assembled in the housings. Wherein the contact module includes an insulator, a differential pair fixedly mounted on the insulator and a ground contact. In order to reduce the signal crosstalk in the signal transmission process, the insulator of the contact module is also equipped with a shielding plate. For example, the Chinese patent with the authorized announcement number CN202217874U and the authorized announcement date is 2012.05.09 discloses a high-speed transmission with shielding grounding structure The connector includes a seat body and a box body arranged in the seat body, wherein the seat bo...
