When it comes to plug products, I firmly believe that everyone knows what it is used for, and plugging in the power socket can display the electromagnetic energy of the electrical equipment driver. 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. CEE connector CEE standard industrial plug socket is an explosion-proof socket, and the temperature is limited below 32 degrees. 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.Plugs can be divided into civil plugs and industrial plugs. The plugs that people usually use at home are civil plugs. Industrial plug refers to the plug used in industrial production, which is commonly used with industrial plug for electromagnetic energy transmission of large and medium-sized industrial equipment. As a unique electronic device, industrial plug has its own set of classification standards. Let me teach you how to classify.First, according to the specifications and types of zoning:UM/CEL, VCE, CDD, T-FAEK, SBC, ASI, PSD, SAUS, PSE, ONI, UP, etc.Second, according to the structural zoning:According to different structures, industrial plugs are divided into two-core plugs, three-core plugs and multi-core plugs. 2-core plug: refers to a plug with two pins. The pin is inserted in the shape of a block or a circular pin. The specifications of each country and region are different. Some pins are inserted in the shape of a block or a round pin, for example, in China, a round pin is used for insertion in Europe.3-core plug: one more grounding pin than 2-core plug, used as grounding device. You may think that there is just one more touch component, and lifting a new pin will cause a series of structural problems. How to assign the size, diameter and the spacing between the pins must be considered, so its product structure is much more complicated than that of 2-core.For multi-core plugs, this is even more complicated. Most of the 4-core and 5-core plugs are manufactured by manufacturers according to customers' regulations. In addition to the effective design structure of the product itself, it is also necessary to fully consider the characteristics of mechanical equipment that can not meet the requirements in plug application.Three, according to the role of zoning:Industrial plugs can be divided into conversion plugs, injection plugs and assembly plugs according to their functions. Switching plug: Each of our electricity consumption standards is different. For a simple example, when we apply British industrial plug, it can't be used. At this time, we need to change it with a switching plug. The function of the switching plug is to convert a national industrial standard plug into a national industrial standard plug, which can be used in another country.Injection molding plug: This kind of plug is a kind of plug that fuses the plug and the wire through the high temperature and high pressure of the plastic mold to produce a detailed assembly. Once it is formed, the plug and the wire can't be disassembled. This kind of plug has the advantages of safety and durability. If we go to the sales market to buy plugs, we will find that the vast majority of several large plugs are all plugs with good injection molding technology.
