The switch knob 132 is disposed in the upper cavity 16, and the cover 133 is disposed on the top end 11c of the housing body 11 to cover the upper part of the upper cavity 16.

Referring to fig. 6, in the present embodiment, specifically, the switch housing 131 includes a main housing 1311 and a boss 1312 disposed along an outer circumference of the main housing 1311 in a protruding manner. Referring to fig. 3 and 4, the main housing 1311 is accommodated in the switch accommodating groove 112, and the boss 1312 is disposed at the edge of the notch of the switch accommodating groove 112. A gasket 1314 is sleeved on the bottom surface of the boss 1312 contacting with the edge of the opening of the switch receiving groove 112, and the gasket 1314 can cover the bottom surface of the boss 1312 and the outer peripheral side surface of the main casing 1311. The switch case 131 is placed in the switch receiving groove 112 with gaskets 1314 between the boss 1312 and the notch of the switch receiving groove 112 and between the main housing 1311 and the groove wall of the switch receiving groove 112. The sealing gasket 1314 is arranged to further seal the contact surface between the switch housing 131 and the switch receiving groove 112.

Referring to fig. 6 again, the switch housing boss 1312 is further provided at the periphery thereof with opposite mounting lugs 1313, the mounting lugs 1313 are provided with screw holes therein, and the switch housing 131 is fastened to the top end 11c of the housing body 11 by screws to further compress the gasket, thereby achieving a better sealing effect. One of the mounting ears 1313 has a fool-proof structure disposed thereon for facilitating identification of the mounting position of the switch housing 131 and the top end 11c of the housing body 11.

The switch button 132 is pivotally connected to the top end 11c of the housing main body 11, an opening matched with the switch button 132 is formed in the cover 133, so that the switch button 132 is exposed to the outside, and the switch button 132 is used for controlling the charging gun to be turned on and off from the outside.

Referring to fig. 7, the cover shell 133 includes a head portion at a front end and a tail portion at a rear end, the tail portion of the cover shell 133 is close to the tail end 11b of the housing body 11, the tail portion of the cover shell extends downward to form an inclined surface, and an elastic buckle 1331 is protruded from a side of the tail portion of the cover shell facing the housing body 11.

The elastic buckle 1331 is of an arch structure seen from bottom to top, a boss buckling position 13311 is arranged at the lower end of the middle part of the front side of the elastic buckle 1331, and a chamfer 13312 is designed on the boss buckling position 13311. The fastening position 113 is arranged on the housing main body 11, and the boss fastening position 13311 is matched with the fastening position 113 to clamp and fix the cover shell 133 on the top end 11c of the housing main body 11. The fastening position 113 is designed with a guide angle, which cooperates with the chamfer 13312 on the boss fastening position 13311 for guiding assembly of the cover shell 133. It should be noted that the fastening position 113 is located at the rear end of the upper cavity 16 and is communicated with the upper cavity 16. The fastening portion 113 is formed between a pair of side members 31 connected to the top end 11c of the skin member 11, a cross member 32 connected to the pair of side members 31, and the top end 11c of the skin member 11. The fastening portion 113 does not vertically penetrate through the top end 11c of the housing main body, and the fixing of the cover 133 does not affect the overall waterproof performance of the housing main body 11.

In summary, the front end 11a, the top end 11c and the rear end 11b of the housing body 11 are sealed by different sealing structures, so that the housing body 11 can be effectively waterproof and dustproof.

In addition, it should be noted that, besides the purpose of waterproof and dustproof of the housing main body 11 of the charging gun, the top end 11c of the housing main body 11 also needs to have a drainage effect, because the top end 11c of the housing main body 11 is located at a vertical upward position during the use of the charging gun, and further because the top end 11c of the housing main body 11 generally has an arc design gradually widening from top to bottom, during the use, the water accumulation phenomenon is easily generated in the upper cavity 16. If the accumulated water cannot be removed for a long time, the pivot for fixing the switch button 132 and the switch module of the switch housing 131 may be corroded to cause the charging gun to break down, and the accumulated water may slowly permeate into the inner cavity 17 from between the switch housing 131 and the switch accommodating groove 112, thereby causing a potential safety hazard to the use of the charging gun.

Therefore, referring to fig. 2 and 8, the rear end of the upper cavity 16 is further provided with a drainage channel 114 transversely penetrating through the upper cavity 16, and the drainage channel 114 is located at the lowest end of the upper cavity 16 in the vertical direction. Both lateral ends of the drain groove 114 are exposed to the outside of the case main body top end 11c, so that the water entering the upper cavity 16 is accumulated in the drain groove 114 and is discharged to the outside. The drainage channel 114 is arranged to drain accumulated water infiltrated into the gap between the cover shell 133 and the top end 11c of the shell body 11 in time, so as to ensure that the inner cavity 17 has no accumulated water.

Referring to fig. 1 and 4, the present application further provides an integrated charging gun 100, where the integrated charging gun 100 includes the above-mentioned charging gun sealed housing 10, and further includes a terminal 20 disposed in the gun head 12. The outer surface of the terminal 20 is provided with a terminal sealing ring 21, the gun head 12 is provided with an inner mounting hole 122, and the terminal sealing ring 21 arranged on the outer periphery of the terminal 20 in the gun head 12 is pressed by the inner mounting hole 122 of the gun head 12, so that the contact surface between the terminal 20 and the gun head 12 is sealed. By arranging the sealing rings on the outer surface of the gun head 12 and the outer surface of the terminal 20, the gun head 12 of the integrated charging gun 100 can achieve a complete sealing effect.

The invention provides a charging gun sealing shell 10 which comprises a shell main body 11 in an integrated design, a gun head part 12 inserted at the front end 11a of the shell main body 11 and a switch part 13 arranged at the top end 11c of the shell main body 11.
