Shield plate component and contact module, and high-speed electric connector

Abstract

The invention relates to a shield plate component and a contact module, and a high-speed electric connector. The contact module comprises an insulator, a grounding contact, a signal contact, and the shield plate component; the shield plate component comprises a contacting shield plate, an auxiliary shield plate; the auxiliary shield plate is in electric contact with the contacting shield plate; the contacting shield plate comprises a shield and a shield plate hole arranged on the shield; a contact sheet protruded to one side of the auxiliary shield plate is arranged at a hole edge of the shield plate hole, the contact sheet and the shield are integrally bent and molded; an avoidance channel for enabling the contact sheet to pass through is formed on the insulator, the contact sheet is in conductive contact with the grounding contact, and a contact sheet via hole for penetrating the contact to penetrate through is formed on the auxiliary shield plate, and an seal cap part for capping the shield plate hole is arranged on the auxiliary shield plate. The seal cap of the auxiliary shield plate contacts the shield plate hole on the shield plate, the capacity of resisting the signal crosstalking by the grounding contact is improved, and the problem that the existing contact module is bad in signal crosstalking resistance is solved.

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...
