Problems solved by technology

When the traditional grounding method is used for assembly, the grounding reliability of each grounding element part needs to depend on other components, and there are often phenomena such as difficult wiring and poor grounding; moreover, the traditional wiring method is realized by interconnecting wires, and the diameter of the wires is impossible due to space constraints. If it is too large, the parasitic inductance is often large, and the impedance of the wire increases sharply in the EMC test of electrostatic discharge, fast transient burst and other EMC projects that contain a large number of high-frequency interference signals, resulting in grounding failure.

Abstract

The invention discloses a hood type power distribution terminal electrical assembly grounding device. The hood type power distribution terminal electrical assembly grounding device mainly comprises a cover plate, and a support and a grounding terminal which are installed on the cover plate. The hood type power distribution terminal electrical assembly grounding device is characterized in that a plurality of installation holes connected with an external member and with metal pieces embedded in are formed in the cover plate, a grounding piece is arranged on the inner side of the cover plate, the grounding piece is connected with a metal piece and a support through connection pieces, and the grounding terminal is connected with the grounding piece. The hood type power distribution terminal electrical assembly grounding device not only can simplify an assembly mode, but also greatly improves ground connection reliability of a power distribution terminal.

Description

technical field [0001] The invention relates to the technical field of grounding of power distribution terminals, in particular to a cover-type power distribution terminal electrical assembly grounding device. Background technique [0002] As a common structural form of power distribution terminals, the shroud structure often has a very narrow internal space and relatively dense components and connectors. When the traditional grounding method is used for assembly, the grounding reliability of each grounding element part needs to depend on other components, and there are often phenomena such as difficult wiring and poor grounding; moreover, the traditional wiring method is realized by interconnecting wires, and the diameter of the wires is impossible due to space constraints. If it is too large, the parasitic inductance is often large, and the impedance of the wire increases sharply in the EMC project test that contains a large number of high-frequency interference signals su...
