AI Technical Summary
In existing power wiring assemblies, the male and female pins are prone to seizing, making disassembly inconvenient and potentially causing deformation, which affects use.
A power wiring assembly was designed, including a limit stop and a locking element. The limit stop restricts the insertion length, and the locking element switches between locked and unlocked states to ensure stable connection of the plug and easy disassembly.
It achieves stable connection and convenient disassembly of the power wiring assembly, avoids pin seizing and deformation, and reduces maintenance costs.
