I. Principle of waterproof industrial plug. A socket into which one or more circuit wiring can be inserted, through which various wiring can be inserted to facilitate connection with other circuits. Embedded socket is embedded in the integrated communication cabinet, which is a power supply device that provides basic DC power for communication and data equipment in the same cabinet. It also has certain versatility. Industrial plugs are suitable for industry, generally divided into 3-core, 4-core, 5-core, etc. The current is generally divided into 16A, 32A, 63A, 125A, 250A, 420A, etc., and the protection level can be divided into IP44 and IP67, which are relatively conventional. Generally, it is used with industrial sockets and industrial connectors.Another waterproof industrial plug is to cover the plug with a layer of plastic sheath, which can isolate the plug from the external gas and prevent the precipitation and moisture in the gas. In cold and humid places such as shower room, bathroom, restaurant kitchen, etc., it is often necessary to use electricity. The application of general power socket can't guarantee watering, so we must choose power socket.II. Classification of waterproof industrial plugs1. According to specifications (outer diameter specifications) M12, M14, M15, M16, M18, M19, M20, M23, M24, M28 and M342. Press led power socket, waterproof route plug, waterproof switch power plug, waterproof automobile plug, dc/ac power socket, multimedia system power socket, waterproof cable plug and power socket.3. According to the number of cores and their appearance, 1 -12 cores, mini plug, standard plug, big D plug, waterproof electronic wire, SM half-air connection, extension line union, T-type tee power socket, Y-type power socket and Yituo multi-channel power socket.III. Installation of waterproof industrial plugsThe selection and installation of outdoor waterproof industrial plugs should pay more attention to the following problems than indoor ones: the power socket should be installed in the hidden position of the house against the wall as far as possible, and it is not easy to get wet in rainy days; It is best to cut off the outdoor power supply in rainy days to prevent power failure.Although the appearance design of power outlets seen by people in the sales market is the same, the quality of power outlets of different well-known brands varies greatly. Therefore, when purchasing, you should choose well-known brands and power outlets with safety labels. The state of power outlets is also divided into different grade specifications, and the higher the grade, the higher the safety factor of power outlets. When purchasing outdoor waterproof industrial plugs, you should choose the ones with higher safety level. Generally, it is necessary to see that the level has not been ip55, and it can meet the requirements only if the level is around ip55.
