[0006] According to another embodiment of the present invention, the rear end of the gun body is further provided with a cable clamp and a cable clamp ring for clamping the charging cable, the cable clamp is placed in the cable clamp ring, the cable clamp ring is connected to the rear end of the gun body, and the cable clamp clamps the charging cable.

[0007] According to another embodiment of the present invention, a sealing ring is further provided between the cable clamp and the charging cable.

[0008] According to another embodiment of the present invention, the power terminal is further connected to the charging cable by welding.

[0009] According to another embodiment of the present invention, the gun body further includes an upper shell and a lower shell, and the upper shell and the lower shell are locked and fixed together by a cable clamp.

[0010] According to another embodiment of the present invention, the gun body and the gun head are further plug-connected and fixed together by bolts.

[0011] The beneficial effect of this utility model is that it improves the current carrying capacity of the charging gun terminal through the double-ended split slot terminal and power terminal, which can greatly increase the charging current and shorten the charging time to meet the demand for fast charging. By quickly and conveniently replacing the charging gun head to replace the damaged terminal, the operating and maintenance costs of the charging pile are greatly reduced.

[0015] Figure 1 It is a structural diagram of the present utility model.

[0016] As attached Figure 1 As shown, a replaceable gun-head charging gun includes a gun body 1, a gun head 2, a double-ended split groove terminal 3, a power terminal 4, a signal terminal 5, and a PCB board 6. The gun body 1 and the gun head 2 are detachably connected together, the double-ended split groove terminal 3 is fixed in the gun head 2, and the power terminal 4, the signal terminal 5, and the PCB board 6 are fixed in the gun body 1. The double-ended split groove terminal 3, the power terminal 4, and the signal terminal 5 are all electrically connected to the charging cable in the gun body 1, and the signal terminal 5 is electrically connected to the PCB board 6.

[0017] A temperature sensor 7 and a temperature control switch 8 are fixed in the gun body 1 . The temperature sensor 7 is electrically connected to the charging cable in the gun body 1 , and the temperature sensor 7 is electrically connected to the temperature control switch 8 .

[0018] The tail end of the gun body 1 is installed with a cable clamp 9 and a cable clamp ring 10 for clamping the charging cable. The cable clamp 9 is placed in the cable clamp ring 10. The cable clamp ring 10 is connected to the tail end of the gun body 1. The cable clamp 9 clamps the charging cable.

[0019] A sealing ring 11 is provided between the cable clamp 10 and the charging cable.

[0020] The power terminal 4 is connected to the charging cable by welding.

[0021] The gun body 1 includes an upper shell and a lower shell, which are locked and fixed together by a cable clamp 10.

[0022] The gun body 1 and the gun head 2 are plug-connected and fixed together by bolts.

[0023] The charging gun improves the current carrying capacity of the charging gun terminal through the double-headed split slot terminal 3 and the power terminal 4, which can greatly increase the charging current, shorten the charging time, and meet the user's needs for fast charging. When the double-headed split slot terminal 3 and the power terminal 4 are contaminated or worn, it will not cause serious charging heat, which greatly reduces the user's use risk. When the double-headed split slot terminal 3 and the power terminal 4 are accidentally damaged, or the terminals are severely worn in the later period of the charging gun's life, the temperature sensor 7 transmits the temperature information to the background system. The operator can detect abnormal heating and pinpoint the damaged charging pile through the background system, so that the gun head 2 can be quickly and conveniently repaired, greatly reducing the operation and maintenance costs of the charging pile.
