Description

Technical Field

[0001] The utility model relates to the field of electrical connection, in particular to a power-changing connector for integrally assembling and disassembling a low-voltage module. Background Art

[0002] At present, the new energy industry is developing rapidly, and battery swap connectors are widely used in new energy vehicles. The assembly and disassembly process of the low-voltage components of the battery swap connector: generally, the front and rear mounting plates are used to fix the low-voltage signal terminals, and then the front and rear mounting plates are fixed by locking the front and rear shells to fix the low-voltage components. Its defects are: First, this fixing method requires two front and rear shells to lock the low-voltage components. After the low-voltage mounting plates are closed, they are locked with bolts. If the low-voltage terminals shake or get stuck, they need to be readjusted. At the same time, there are a large number of low-voltage terminals, ranging from several to dozens, which usually requires repeated installation. The terminals are easily damaged during the assembly process. Therefore, this method is complicated and difficult to assemble, consumes more man-hours, and has a high rate of poor assembly; second, each time the low-voltage components are inspected and replaced, the shell needs to be removed, which is easy to cause the power terminals to loosen in the long run. After re-locking the shell, it is difficult to ensure the contact performance of the power terminals, affecting product performance. Utility Model Content
