With the development of society, nowadays, we can't turn on electrical equipment and electricity more and more, so we need something to connect them, that is, connectors, plugs and sockets for short. IP54, that is, dust prevention is level 5: dust intrusion cannot be completely prevented, but the amount of dust intrusion will not affect the normal operation of the product; Waterproof grade 4: prevent splashing water from invading, and prevent splashing water from all directions from invading. The power socket has one or more seats into which 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. As its name implies, industrial plug is a kind of plug used in industrial environment. Nowadays, industrial plug is widely used in many industries and fields.Therefore, it is quite different from the traditional ordinary plug in its reliability, durability, protection level and so on, while the ordinary plug is still quite different. The following are the characteristics of various aspects:1. Durability: Because the shell of industrial plug is made of high-quality engineering plastics, it has high strength, impact resistance, fear of falling and trampling. The use of industrial plugs has an anti-aging effect, so that industrial plugs can be used not only indoors, but also outdoors. The industrial plug can be within 5,000 times of the normal plug operation cycle.2. Universality: Because the manufacturing standards used by industrial plugs are the same as those of international standards, industrial plugs can match the use of both domestic and international products. At the same time, there are many kinds of industrial plugs, which can meet various purposes.
