Abstract

The invention relates to a common grounding structure. The structure comprises a mounting bolt, a mounting nut, a wiring bolt and a wiring nut, the mounting bolt and the wiring bolt are connected to form a double-head grounding bolt of an integrated structure through a boss, and the two side surfaces of the boss are a common conduction contact surface and a wiring conduction contact surface; the mounting nut and a mounting covering cap sleeve the periphery of the mounting bolt from inside to outside, the wiring nut and a wiring covering cap sleeve the periphery of the wiring bolt from inside to outside, and the diameter of the boss is larger than the diameters of the mounting bolt and the wiring bolt. According to the common grounding structure, it can be guaranteed that the conduction contact surfaces are not easily corroded, the electric performance is not easily aged and lowered, the technology is convenient and easy to implement, the anti-loosening and protection effects are extremely good, and the production cost is low.

Description

technical field [0001] The invention relates to a conductive connection design of a common grounding point in a negative line, in particular to a common grounding structure and its use method, which is particularly suitable for ensuring that the conductive contact surface is not easily corroded, and that the electrical performance is not easily degraded due to aging, and the process is realized simple. Background technique [0002] At present, in the electronic and electrical circuits of road vehicles, construction machinery and ships, the conductive connection between different components in the electronic and electrical circuits is often involved, mainly for the common ground point (Common Ground) in the negative line (also known as the ground line). Point) conductive connection. The common ground point is the position designed on the common ground parts (Common Ground Parts) for the negative electrode lines of the electrical products in the electronic and electrical circ...
