The application of industrial plug is relatively extensive, and it is an ideal device of the new generation. 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 universality. Socket A socket into which one or more circuit wires can be inserted, through which various wires can be inserted to facilitate connection with other circuits. 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 normally open switch of the electromagnetic switch is arranged on the power line; and the normally open switch of the electromagnetic switch is connected with the jack. He can be seen in many places, such as steel smelting, petroleum chemical industry, electric power and electronics, railways, construction sites, airports, mines, mining sites, water supply and drainage treatment plants, ports and docks with ships, shopping malls and hotels, etc. Industrial plugs are closely related to our life, so how should consumers buy industrial plugs?1. Appearance: Generally, good products have a textured appearance, good and uniform color, clearly visible printed characters, and the hardness and flame retardancy of the materials used meet certain requirements. It seems that if the surface of the product is coated with a layer of oil, it looks smooth, but the weight is very light. Please never buy the above featured products, because this material is not good in flame retardant, and it may bring fire hazards to electricity.2. Feeling: When you buy it, you must shake it first to make sure there is no sound in it and it feels thick. Pull the power cord again. Make sure the power cord and socket are firmly connected.3. Structure and material: To judge the quality of the socket, we should first look at the socket sleeve, which can be seen from the jack. Generally, the material should have a smooth surface, and it is required not to have copper rust, with a thickness of 0.5mm-0.8mm The cross-sectional area of the power cord is also one of the quality standards for judging, and it must be consistent with the standard cross-section. If the cross-section is too small, the power cord will become hot and soft after long-term use, and more importantly, improper selection will cause fire.4. Find a good brand: Famous brand products have been strictly tested by the market for a long time, and the materials and production will be tested by strict quality standards, so a good brand can make us buy with confidence.These are the standards for purchasing high-quality industrial plugs. If you want to buy industrial plugs, you can refer to the above methods.
