Problems solved by technology

[0004] However, the electromagnetic shielding performance of this double-layer shielding sheet structure is not ideal from the actual test. There is a long gap between the bottom shrapnel and the metal shell, which is prone to EMI leakage, and the upper shrapnel is lapped on the bottom shrapnel. If the bottom layer shrapnel shield fails, the upper layer shrapnel shield will also fail, and there is no real double-layer shielding effect.

Abstract

The invention discloses a connector shell (100). The connector shell (100) comprises an insertion port (10) and a shielding sheet structure (2), wherein the shielding sheet structure (2) is arranged at the periphery of the insertion port (10) and comprises a plurality of first elastic sheets (21) and a plurality of second elastic sheets (22), the plurality of first elastic sheets (21) are arranged in parallel, the plurality of second elastic sheets (22) are arranged in parallel and are arranged at outer sides of the first elastic sheets, each first elastic sheet and each second elastic sheet comprise first end (211 and 221) and second ends (212 and 222), the first ends (211 and 221) are fixedly connected with the connector shell, and the second ends (212 and 222) freely extend towards the connector shell. According to the structure of the connector shell, the first elastic sheets and the second elastic sheets respectively form a shielding layer with the metal shell so as to respectively develop a shielding effect, so that a dual-layer electromagnetic interference (EMI) effect can be reliably achieved.

Description

technical field [0001] Embodiments of the present invention relate to a connector housing, in particular to a shielding plate structure for the connector housing. Background technique [0002] Connectors currently used in the field of high-speed data communication generally have a connector housing outside the connector to shield electromagnetic waves (EMI). The connector housing generally includes a metal housing and a metal shielding sheet structure connected to the outer periphery of the metal housing. The shielding sheet structure is suitable for elastic contact with an external mounting opening to fix the metal housing to the mounting opening. , and prevent electromagnetic waves from leaking from the gap between the metal shell and the installation opening. [0003] In order to achieve high-demand electromagnetic shielding (EMI) performance, existing connector housings have adopted a double-layer shielding sheet structure. The double-layer shielding sheet structure in...
