Abstract
A waterproof structure applied to an alternating current plug and an alternating current socket includes a plug body and a socket body. The plug body has an inserting portion, a covering portion formed thereon, a limiting portion formed between the plug body and the covering portion, and a washer positioned at one end of the limiting portion to be adjacent to the inserting portion. The socket body has an opening relative to the inserting portion for insertion, and a receiving portion formed thereon suitable for the covering portion to be engaged. The structure will not only be more stable than before to prevent separation occurred by an external force, but also be waterproof equally.
