The utility model relates to the technical field of charging guns, and particularly discloses a waterproof, anti-heating, anti-
electric shock and anti-arc structure of a conversion head, which comprises a CCS1 gun head and an NACS interface connected with the CCS1 gun head, a first
copper contact pin, a first
signal pin and a PCBA circuit board are arranged in the CCS1 gun head, a first button and a second button are arranged on the NACS interface, and a second
copper contact pin is arranged on the first button. The inner side of the first button and the inner side of the second button are each provided with a microswitch electrically connected with the PCBA circuit board, a
copper bar, a second copper pin and a second
signal pin are arranged in the NACS interface, and a waterproof sealing strip is arranged between the CCS1 gun head and the NACS interface. According to the utility model, the first copper pin and the second copper pin are both connected with the copper bar in a pressure riveting manner, the first button and the second button are internally provided with the microswitches, power is
cut off before the gun is pulled out,
electric arc generation is avoided, the
electric arc prevention function is realized, and the
electric shock prevention function is realized by arranging the safety door structure at the output end of the CCS1 gun head. The waterproof sealing performance is improved by arranging the waterproof sealing strip, and the waterproof grade is improved.
