Technical Field

[0001] The utility model relates to the technical field of cables, and in particular to a safety cable for a charging pile. Background Art

[0002] Charging pile is a kind of energy replenishment device that provides power for electric vehicles. Its function is similar to the gas pump in the gas station. It can be fixed on the ground or wall and installed in public buildings (charging stations, shopping malls, public parking lots, etc.) and residential parking lots. It can charge various types of electric vehicles according to the voltage and current adjustment. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.
