[0002] The connector of general electronic products and the plug pin of electrical appliances are called plugs. The household AC power plug and socket have a rod-shaped or copper plate-shaped male connector protruding to physically insert into a female connector-type power socket with a slot or cavity. The waterproof performance of the plug is particularly important. Especially when using the plug outdoors, the waterproof effect of the plug affects the use effect of the plug and is also related to the safety of the user and the equipment.

[0003] According to a disclosed waterproof and heat-dissipating plug structure (Publication No.: CN220797237U), in the above application, heat generated by the plug can be effectively absorbed and released by setting heat-dissipating blocks and heat-dissipating holes, reducing heat accumulation, keeping the plug in a low-temperature state, and thus prolonging the service life of electrical equipment; by increasing the heat-dissipating surface area and promoting heat transfer, the plug structure can effectively reduce the temperature of electrical equipment during high-load and long-time operation, improving the stability and reliability of electrical equipment; through the waterproof design, moisture can be prevented from entering the contact part between the socket and the plug, reducing the risk of electrical components getting damp and lowering the potential hazards of electric shock and short circuit.

[0004] However, in the actual use process of the above equipment, the waterproof design can only prevent moisture from entering the contact part between the socket and the plug. When using the plug outdoors, in rainy weather, the male connector on the plug is easily wetted, and when the plug is inserted into the socket at this time, it is easy to cause a circuit break, thus damaging the machine. In view of this, we have proposed a plug waterproof structure and an electric vehicle charging pile. Content of the Utility Model
