Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage connectors, in particular to a replaceable high-voltage connector. Background Art

[0002] High-voltage connectors are connectors that can withstand high-voltage currents. Typically, they are used to connect high-voltage equipment in power systems and industrial control systems, such as transformers, switches, cables, etc. These connectors are different from general low-voltage connectors and can ensure stable current transmission and prevent problems such as arcing and leakage.

[0003] The male and female end covers on high-voltage connectors usually adopt a single-layer snap-on structure. Once the sealing between them is weakened, the joint may become loose, resulting in poor contact between the cables and affecting the smoothness of the circuit.

[0004] In addition, the terminals on the high-voltage connector, especially the female terminals, are often assembled to the high-voltage connector by fastening with multiple bolts, but this fixing method is cumbersome and not easy to replace. Utility Model Content
