First of all, the key difference between industrial plug and general civil socket is reflected in the shape of socket: as the saying goes, which socket has which cover. 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. CEE connector CEE standard industrial plug socket is an explosion-proof socket, and the temperature is limited below 32 degrees. Industrial plugs are applicable to industry. They are generally divided into 3 cores, 4 cores, 5 cores, etc. the current is generally divided into 16a, 32a, 63A, 125A, 250A, 420a, etc. the protection grade can be divided into IP44 and IP67, which are relatively conventional. Generally, it is used together with industrial socket and industrial connector. Some high-power sockets use cylindrical industrial plugs, so the opposite socket should use circular sockets, so that the socket and power plug are industrial plugs. There are significant differences between industrial plugs and general civil sockets (also known as national standard sockets) in the above shapes. GB sockets are made of flat metal, while industrial plugs are made of circular copper columns. Industrial plugs are generally three-phase four wire or three-phase five wire, and there are more sockets than national standard sockets.

Second, the requirements and characteristics of waterproof sockets in the workplace are different:

Most of the working places of industrial plugs and sockets are outdoors. One situation that the outdoor natural environment must deal with together is rainy and snowy days. In order to better avoid endangering all normal work and production and manufacturing conditions under such circumstances, the equipment must be waterproof, IP44, IP67, etc.

Third, the components of the industrial plug are also made of different materials:

The cable on the industrial plug also adopts a unique rubber sheathed flexible cable, that is, a soft and easy to move cable wrapped with vulcanized rubber and rubber sheath. According to the national standard, general cables can only be used in the middle of minus 15 degrees to 50 degrees, while rubber sheathed flexible cables can be used in minus 50 degrees without hard bottom. There is no difficulty in the application of wire core within 65 ℃ above zero. The shell of general socket mostly adopts PC raw materials, which has certain characteristics of high temperature and heat resistance, which is sufficient for general individual users. However, due to the uniqueness of mobile socket, it is often used to produce switching power supply for high-power socket, so the working capacity of flame retardant and fire safety is higher. Therefore, wolf household appliances have high utilization rate and high flame retardant PC polycarbonate aluminum alloy on the socket control panel. It has strong impact resistance, ductility, perseverance, fall resistance, flame retardant and fire safety. It can be safely applied in the middle of minus 60 degrees to 120 degrees. The long-term application safety does not change, and the service life of the socket can be reasonably increased.
