1, waterproof socket is in general embedded in the wall outside the socket plus a waterproof box with a cover, the box and the wall in contact with the place of rubber gaskets, so you can waterproof; some waterproof sockets for the plastic rain sheath, cuttings in the hole down, supporting the special cuttings. There are three-phase four-wire, three-phase five-wire supporting cuttings, cuttings.
2, ordinary wall switches can not be waterproof is mainly due to the external air in the water and water vapor can be through the socket on the socket into the socket, and compared to the ordinary switch, waterproof socket surface will be added to a plexiglass waterproof cover, which can effectively block the outside world of water and water vapor into the interior of the socket, and in addition to the fixed place will also be waterproof pads, which can also effectively block the outside world of water vapor into the socket, the waterproof pads, which can also effectively block the outside world of water vapor into the socket, the waterproof pads. Block the outside water vapor into the socket interior.
3, waterproof socket is in general embedded in the wall outside the socket plus a waterproof box with a cover, the box and the wall in contact with the place of rubber mats, so you can waterproof; waterproof socket for the plastic rain jacket, cuttings in the hole down, supporting the special cuttings. There are three-phase four-wire, three-phase five-wire supporting cuttings, cuttings.
4, for the waterproof connector waterproof performance of the main evaluation criteria is based on ip waterproof grade standard. To see how the waterproof connector waterproof performance, mainly look at the IPXX two digits after XX, the first X is from 0 to 6, the high level for 6; the second digit is from 0 to 8, the high level for 8; so the waterproof connector of the high waterproof level of IP68.
5, the sealing principle: rely on as many as five sealing rings and sealing ring to pressure pre-tensioned sealing. This sealing in the connector thermal expansion and contraction, will not lose the preload, long time to ensure the waterproof effect, water molecules can not be penetrated under ordinary pressure (can be in less than 2M water depth long-term work)
