I believe many people only know that it is a waterproof plug, so what kind of specific power outlet is it? Today, we will talk about power outlets in detail. A switch is arrange between that resistance of the weatherproof socket and the electromagnetic switch; the fuse and the electromagnetic switch are connected with a pow line; the power line is provided with an electromagnetic switch normally open switch which is connected with a jack. 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. Industrial plugs are suitable for industrial use, and are 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 together with industrial sockets and connectors. The combination of power socket and power socket is called cee connector. They must exist at the same time to be meaningful. This is different from our household plugs and sockets. Power outlets and power outlets must be purchased together. There is a great demand for power outlets in the market, but some users do not know how to buy power outlets. When some of our customers told us what power outlets they needed, they didn't express them clearly enough. Today, we mainly talk about some key points of purchasing power outlets for your reference. When you purchase power outlets next time, you can express your needs simply and clearly. First of all, we need to determine the cable current power and cable material size. Knowing these two problems, we can determine how many cores and how big power outlets we need to take, and we can also understand whether we use national standard wires or non-marking wires. As for the connection mode, the welding connection mode is widely used in the market at present, and injection molding is adopted. Another connection mode is screw type, and screw type power socket is mainly used in assembled CEE connector, which is generally used for outdoor cable connection. Screw type connection mode can avoid soldering iron brought by welding, which will be more convenient and convenient to use. However, screw type connection mode is relatively expensive, so general manufacturers choose injection molding for connection. Then, with regard to connector types, plugs matched with different wire diameters are also different. For those with smaller wire diameters, we generally choose to use small connectors, which can not only save cost but also save volume, which is a relatively better choice. However, for those with larger wire diameters, large power outlets are needed to match, so as to ensure their normal use and stable performance. In any case, the most important thing is that customers need to know their needs and what we need to clearly record, and then it is generally not wrong to purchase according to this demand. We mainly summarize the following points. Everyone comes down in order according to their own needs, and then actively communicates with the manufacturers, so that you can get the power outlet you need. 1. The specification of the cable determines the number of cores and types of wires of the power information socket. Figure 2. There are many kinds of plugs, and the main ways we should choose are docking, the occasion of use and the size of the power outlet. There are also color requirements, which will not be hard and fast unless it is a special occasion. 3. Other special education requirements, other special design requirements mainly include the cold resistance of specific analysis data, which can be used in ultraviolet irradiation occasions, the need to inform the power socket of the time management and work intensity required by ultraviolet irradiation, the special environmental requirements of waterproof grade, special wiring methods, and so on.
