Abstract

The invention provides an electrical cabinet door panel grounding device. The electrical cabinet door panel grounding device comprises a first contact component and a second contact component, whereinthe first contact component comprises a first contact, the second contact component comprises a second contact, the second contact is flocculent metal wires, and the first contact and the second contact are opposite to each other. In the electrical cabinet door panel grounding device, when the first contact is contacted wit the second contact at any angle, the first contact and the second contactare contacted in surface, so that a contact area of the first contact and the second contact is always guaranteed, good conductivity between the cabinet body and the door panel is ensured, and further, the whole electrical cabinet is guaranteed to have good shield performance.

Description

technical field [0001] The invention belongs to the field of electric connection, in particular to a grounding device for an electric cabinet door plate. Background technique [0002] The electrical system is installed in the electrical cabinet of the locomotive, so the electrical cabinet needs to be grounded to shield external electromagnetic interference. Generally, the cabinet body and the cabinet door of the electrical cabinet are separated. In order to ensure the good electromagnetic shielding performance of the entire electrical cabinet, when the cabinet door is closed, there must be good electrical conductivity between the cabinet door and the cabinet body to ensure that the cabinet body is grounded at the same time. , The cabinet door also has reliable grounding performance. [0003] Patent document CN207625086 U discloses a grounding device for an electrical box door panel, which includes a grounding baffle, a grounding contact and a grounding contact holder. The ...
