1. Waterproof socket is to add a waterproof box with a cover outside the general wall socket, and there is a rubber mat where the box contacts the wall, so it can be waterproof; Some waterproof sockets are made of plastic rain-proof sheaths, with the inner hole facing downwards and supporting special skewers. There are three-phase and four-wire, tn-s supporting stand and stand.
2. The common wall switch can't be waterproof mainly because the water and steam in the outside air can enter the socket through the jack on its socket. Compared with the common switch, a waterproof cover made of plexiglass will be added to the surface of the waterproof socket, which can effectively prevent the outside water and steam from entering the socket. In addition, there will be a waterproof pad at its fixed place, which can also effectively prevent the outside steam from entering the socket.

4. The main evaluation standard for waterproof performance of waterproof connectors is ip waterproof grade standard. Look at the waterproof performance of waterproof connector, mainly look at the last two digits XX of IPXX, the first digit X is from to 6, and the high grade is 6; The second digit is from to 8, and the high grade is 8; Therefore, the waterproof connector has a high waterproof rating of IP68.
5. sealing principle: rely on up to 5 sealing rings and sealing rings to pre-tightly seal with pressure. This kind of seal will not lose the pre-tightening force when the connector expands with heat and contracts with cold, ensuring the waterproof effect for a long time, and it is impossible for water molecules to penetrate under ordinary pressure (it can work for a long time in a water depth of less than 2M).
