AI Technical Summary
When existing connectors are plugged in and out under high voltage, the pins and socket surfaces are prone to burning due to discharge, which increases contact resistance and damages the connector.
It adopts a square pin and socket structure with embedded magnets. The Lorentz force is used to concentrate the electric arc on a specific contact arc surface, avoiding direct contact between the electric arc and the pin and socket. The electric arc is dispersed by the magnetic lines of force of the magnet, reducing ablation.
It effectively avoids the burning of pins and sockets, and improves the reliability and durability of the connector during hot-plugging under high voltage.
