The use characteristics of industrial plugs are different in different use environments, and their application characteristics and functions are obviously different. We can find that the use effect of industrial plugs has certain functions in actual use, especially in the natural environment encountered by manufacturing industries such as petrochemical ironmaking and mining industrial equipment in the first industrial chain and manufacturing industries such as industrial hotels in the third industry chain. Therefore, high regulations are clearly put forward for industrial plugs. A switch is arranged between the weatherproof socket resistor and the electromagnetic switch, the fuse and the electromagnetic switch are connected with a power line, the power line is provided with a normally open switch of the electromagnetic switch, and the normally open switch of the electromagnetic switch is connected with the jack. 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.On the whole, industrial plugs in various manufacturing industries have the following characteristics:1. High safety factor: Because the key links in industrial production are closely linked, once a problem occurs in one stage, it is likely to cause great harm to other stages, so industrial plugs must have a very high safety factor index value, and their functional design must meet the application requirements and technical standards in industry, so that industrial production can have great security. In addition, it is usually necessary to design some safety protection countermeasures cooperatively.2 Power maintenance role of moisture-proof and safe use: the design scheme of this role can greatly improve the stability of industrial plugs, which leads to safer and more stable use of products in daily use, and the high safety factor of products with wider environmental conditions is a proof.3. High-quality closed type and its maintenance equipment can make the socket plugs connect with each other more strongly, and it is not easy to fall off.4. Long service life of industrial plugs: The long service life of industrial plugs is to ensure the safety of manufacturing. 5. High temperature resistance and flame retardant rating: Industrial production equipment is usually open 24 hours a day, so the specified high temperature resistance and flame retardant rating of power sockets are usually high.High practicability: manufacturing industries are different. If industrial plugs are only made for one manufacturing industry, both product cost and application cost are very high.
