Description

Technical Field

[0001] This utility model relates to the field of grounding technology, and in particular to a fixing mechanism for grounding. Background Technology

[0002] Grounding is an important component of the electrical system of automobiles and other equipment. It refers to connecting the metal casing or negative terminal of electrical equipment to the metal components such as the vehicle body through a wire to form a circuit. The principle is to use the metal body as a common negative terminal to replace an additional negative wire, simplifying the circuit layout. Its main functions include conducting current, protecting equipment and personnel safety, and stabilizing circuit voltage.

[0003] The grounding process requires the use of a fixing structure. Common fixing structure types include bolt type, clip type, and welding type. The main purpose is to use mechanical or welding methods to firmly fix the grounding wire terminal to the metal component of the vehicle body to ensure good conductive contact. This can prevent the connection from loosening or poor contact due to vehicle vibration and avoid circuit failure.

[0004] Traditional grounding fixing often uses single bolt tightening or simple clip connection. The metal contact surface is prone to fretting wear due to vibration, which leads to increased contact resistance and affects conductivity stability. At the same time, bolt tightening depends on manual torque control. If it is too loose, it will loosen easily; if it is too tight, it will cause metal deformation. In addition, the assembly efficiency is low.

[0005] Therefore, it is necessary to provide a fixing mechanism for grounding to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a fixing mechanism for grounding, which solves the problems of vibration, fretting and wear of the metal contact surface of traditional grounding fixing using a single bolt or simple buckle, which increases resistance, while manual control of bolt torque makes it easy to loosen or deform and has low assembly efficiency.

The protective sleeve is installed on the outer surface of the wire, and the two conductive heads are installed at both ends of the wire. The two conductive heads are inserted into the two slots respectively and connected to the fixing bolts by threads.

[0009] Preferably, the conductive base includes a conductive plate and a plurality of mounting holes, wherein the plurality of mounting holes are formed on the top of the conductive plate.
