[0034] Working process: When the device is in use and needs to be installed between the female end 1 and the male end 2, the limit slide bar fixedly connected to the outside of the plug shell 21 corresponds to the slide groove inside the female end 1, and the plug shell 21 is inserted into the inside of the female end 1. The number of slide bars designed at the left and right ends of the plug shell 21 is different, which can ensure the correct connection between the female end 1 and the male end 2. When the plug shell 21 slides on the inside of the female end 1, the plug shell 21 contacts the groove 82, and the groove 82 is set to an inclined shape, which is convenient for squeezing the magnetic card column 81 when the plug shell 21 moves, and the magnetic card column 81 drives the limit slide column 84 to move, and the limit slide column 84 The spring 85 is squeezed, the limit slide 84 is slidably connected to the inner side of the active groove 6, and the magnetic card column 81 is received in the active groove 6. When the magnetic card column 81 is aligned with the bayonet 24, under the elastic thrust of the spring 85, the magnetic card column 81 is engaged in the bayonet 24. At the same time, the first sealing ring 22 fixedly connected to one side of the plug shell 21 contacts the rear side of the female end 1, and the first sealing ring 22 is deformed. The second sealing ring 23 contacts the inner side of the female end 1 and the second sealing ring 23 is deformed.

When the device is in normal use, a certain amount of heat will be generated between the pin inside the female end 1 and the electrical connection insertion channel 26, and the gas will expand and cool due to heat expansion. The expanded gas will enter the sealed space formed by the inner side of the female end 1 and the outer side of the plug shell 21 from the ventilation channel 25, and the gas will enter the active groove 6 from the buffer channel 83 opened on the inner side of the magnetic card column 81 and the limit slide column 84, and then enter the outer edge opening 5 from the active groove 6, and then enter the multi-channel tube 31 from the outer edge opening 5, and then enter the heat dissipation gas storage tank 33 from the multi-channel tube 31. When there is a lot of gas, the gas passes through the heat dissipation gas storage tank 33. The lower through hole of the upper mounting shell 34 enters the inside of the circular balloon 35, and the circular balloon 35 expands. The circular balloon 35 is convenient for storing hot air, and the gas inside the heat dissipation gas storage tank 33 takes away the heat of the heat dissipation gas storage tank 33 through the flow of external gas. After the heat inside the heat dissipation gas storage tank 33 is reduced, the hot air inside the circular balloon 35 gradually enters the heat dissipation gas storage tank 33 and cools down again. Under the action of the circular force of the circular balloon 35, the gas inside the heat dissipation gas storage tank 33 can enter the electrical connection plug 26, thereby achieving the effect of cooling the device and ensuring the service life of the device.
