Description

Waterproof structure of AC power plug and socket

technical field

The utility model relates to a waterproof structure of an AC power plug and a socket, in particular to a structure capable of achieving stable plugging and waterproof effects after the plug body and the socket body are plugged together.

Background technique

Areas with oceanic climate are often attacked by typhoons in summer and autumn, and typhoons bring a lot of rain, causing residents living in low-lying areas to suffer from floods and suffer huge losses in property . Among them, the water ingress into the plugs and sockets of electrical equipment will lead to power failure of the electrical equipment in operation, or even damage or cause electric leakage, and the user will get an electric shock. Therefore, how to avoid water ingress and moisture in the plugs and sockets has become an urgent important issues to be resolved.

Known waterproof structures for AC power plugs and sockets, such as known screw-type waterproof devices for electric wire plugs and sockets, include a clamp that can hold the socket and a clamp that allows the electric wire plug to be just engaged therein. sleeve. The electric wire at the rear end of the electric wire type plug is protruded from the rear end of the sleeve, and a gasket is sleeved on the sleeve; in this way, when in use, the plug in the sleeve is inserted into the socket with a clamp, so that the plug and The socket is clamped naturally, and then a bolt is used to tightly cover the rear end of the sleeve and screw on the sleeve and the fixture. In this way, the bolt is tightly pressed against the sleeve and the washer to achieve the purpose of waterproofing; finally, a nut is inserted from the rear end of the sleeve, and screwed tightly with the thread at the rear end of the sleeve, so as to realize the tight pressing of the wire waterproof function.

Although the screw-type waterproof device of the wire type plug and socket can make the wire type plug and socket realize the waterproof function, a screw must be used to tightly cover the rear end of the sleeve and the Tighten it on the clamp, and then insert a nut from the rear end of the sleeve, and screw it tightly with the thread at the rear end of the sleeve, so as to realize the waterproof function. Therefore, the steps to use it are cumbersome, and there are many components between the plug and the socket, resulting in a relatively complicated structure of the plug and the socket itself. Therefore, the AC power plug and the socket cannot meet the requirements of actual use.

Contents of the utility model
