[0019] The utility model provides a kind of charging gun. In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following will be further described in detail to the utility model with the accompanying drawings, it should be understood that the specific embodiments described herein are merely used to explain the utility model, and are not used to limit the utility model. Figures 1-5 And embodiment, the utility model is further described in detail. It should be understood that the specific embodiments described herein are merely used to explain the utility model, and are not used to limit the utility model.

[0020] A discharge gun, including shell 1, discharge gun terminal 41 is arranged in the shell and constitutes vehicle interface end 12, the other end of the shell 1 has socket terminal 81 and constitutes socket end 11, when using, through the vehicle interface end 12 and vehicle form connection, the socket end 11 can provide electrical energy for external equipment. To improve the safety factor of discharge gun, current protection assembly is also arranged in the shell 1. The current protection assembly includes leakage protection and overcurrent protection.

[0021] ​Further, the current protection assembly comprises a leakage protection module 5 welded on the first PCBA board 4. The first PCBA board is arranged in the middle of the discharge gun, i.e. between the vehicle interface end and the socket end. The leakage protection reset switch 2 and the test switch 3 arranged on the leakage protection module 5 are both arranged to extend out of the other end of the first PCBA board 4 from one end of the first PCBA board 4. The leakage protection module has the same structure as the existing leakage protection module, and its leakage protection mechanism is also realized by detecting the leakage current in the circuit. When the leakage current in the circuit exceeds the set threshold, the leakage protection module triggers the protection action to cut off the power supply or send an alarm signal to prevent electric shock or equipment damage. In order to play an indicating role, the housing is also provided with a leakage protection indicator.

[0022] The current protection assembly further comprises a fuse 6 arranged on one side of the leakage protection module 5, which is welded and connected with the first PCBA board 4. The arrangement of the fuse 6 can quickly cut off the current to ensure the safety of electricity use when the circuit fails or abnormally, such as abnormal increase of current, and the fuse melts after reaching a certain degree.

[0023] The socket end of the leakage protection module 5 is provided with a second PCBA board 7, which is arranged at the socket end through a support. The second PCBA board 7 is provided with a micro switch 8. The micro switch 8 is connected to the second PCBA board 7, and the socket terminal is connected with the micro switch 8. In the embodiment, the socket end is provided as a five-hole socket, including a two-hole socket and a three-hole socket, and the micro switch is provided with two, which are respectively located at the two-hole socket and the three-hole socket. The power supply of the socket is controlled by the micro switch to realize the power-on and power-off of the socket.
