As a connector, industrial plugs are commonly used in factories, power generation equipment, construction engineering, mechanical equipment and other places, and are generally used in combination with industrial plugs. 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. 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. 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. But many people say that I can't use ordinary plugs? What is the difference between industrial plugs and ordinary plugs?1. First of all, industrial plugs and ordinary plugs are completely different in appearance. As the saying goes, "sewer is equipped with manhole cover", the appearance of industrial machinery and industrial plug are closely related. Many high-power machines can't use the copper-sheet-shaped structure of ordinary sockets because of the high current, and all adopt the round socket structure, so industrial plugs can only be cylindrical. Therefore, in order to facilitate the use of various factories and enterprises, industrial plugs and industrial plugs were born together.Industrial plugs can also be easily distinguished from the appearance of ordinary plugs. General plugs are generally flat copper plugs with three teeth or two teeth, while industrial plugs are generally round copper posts. There are also obvious differences from the external material of plugs. The external material of industrial plugs is generally thicker, because it must withstand more severe environmental tests.Figure 2. Different environments make their water resistance different. Industrial plugs are generally used in factories or outdoor environments, which inevitably face the test of rain and snow. In order to be used in these situations, industrial plugs must have certain waterproof performance. Of course, plugs and industrial plugs should be used together. The waterproof grade of industrial plugs is above ip44, which can fully meet the needs of our outdoor use.3. Industrial plugs are made of different materials from ordinary plugs.The cable used in industrial plugs is a special rubber sheathed cable, that is, a kind of soft and easy-to-move cable that does not wrap a layer of rubber or rubber sheath around the wires. Ordinary civil cables can only be used at -15-50 degrees, while the cables used in industrial plugs can be used at -50 degrees, and the cable will not be hardened, and the cable core used at 65 degrees can ensure the stability of performance.Generally, outsourced plugs are all ordinary pc materials, which have certain heat resistance and high temperature resistance, and are absolutely sufficient for general household use. Most industrial plugs are used in high-power industrial machinery, so the heat resistance of plugs is required to be high. Therefore, pc polycarbonates are used in industrial plugs and industrial plug panels. It has the characteristics of flame retardance, fire resistance, impact resistance, good toughness and falling resistance. The utility model is safe to use, usually between-60 and 120 degrees, which greatly prolongs the service life of industrial plugs and industrial plugs.4. Different functions. At present, the commonly used method of industrial plugs and industrial plugs is mobile integral equipment, which takes electricity from the power supply on one side and supplies power for industrial machinery on the other side, and basically requires necessary use; General plugs are basically universal and can be used in general multifunctional sockets.
