According to the increasing global warming phenomenon, countries around the world continue to advocate energy conservation and carbon reduction, so as to slow down the phenomenon of global warming, and also raise awareness of environmental protection. In the daily life of clothing, food, shelter, entertainment, etc. When a large amount of waste is disposed of, it will also generate a large amount of waste gas, carbon dioxide, etc., which affects the environmental quality when handling various types of waste. Among them, vehicles, locomotives, airplanes or ships that pass through various modes of transportation As a means of transportation, but because various vehicles use fuel such as gasoline or diesel, they will emit exhaust gas during operation, which is the culprit of serious air pollution. Vehicles are an indispensable means of transportation in daily life. How to use environmental protection appeals and the ability to use mobility tools has become a problem that modern people must face and solve.

In order to solve the problem of exhaust emissions from vehicles, some people have developed electric vehicles, which are driven by electric energy to drive the vehicles to operate without emitting exhaust gas and causing pollution such as air and environment. The goal of encouraging people to change Use electric vehicles, locomotives, etc. as a means of transportation to reduce exhaust emissions, to improve the air quality of the living environment, and to reduce pollution and damage to the environment and air, then use electric vehicles or locomotives, etc., the most important One of the conditions is that vehicles such as steam and locomotives must be charged to provide energy for operation of steam, locomotives, etc., and the charging method can be charged by the user at home or at a charging station set at a fixed point. Charging vehicles such as steam and locomotives through a charging gun.

Furthermore, the currently used charging gun has a handle that is assembled through the left and right opposite sides, and is internally provided with various components such as a control unit, a push switch, a power cord, a mechanical lock, and the like, and a button is provided outside the handle. Then, the charging connector is arranged on the side of the handle to be connected with the vehicle, and the power supply socket or the generator is connected through the power cord of the other side of the handle to provide the power required for the charging gun to charge the vehicle, but the current charging gun is required. A plurality of resistors are provided through the reciprocating action of the conductive terminals to increase the voltage change amount through the resistor to determine the state of use of the charging gun. However, at present, the plurality of resistors are mostly disposed on the metal wires in the power line, but the resistance is soldered to the metal wires. When the structure of the welded part is weakened and embrittled, the welded part of the charging gun is prone to breakage. Therefore, the manufacturer additionally installs a resistor module inside the charging gun to charge the battery. The internal resistance setting of the gun is bound to occupy the use space inside the charging gun, which leads to the overall volume of the charging gun becoming larger. Due to the increased volume of use is generated a lot of inconvenience.
