Nowadays, industrial plugs and sockets have become the latest generation of ideal power devices in society, and are widely used in various industries, especially in the fields of petrochemical industry, power electronics and so on. 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. 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.Next, I will give you some details about the materials commonly used in manufacturing industrial plugs. I believe you will have a better understanding of this equipment after reading it.The first one is nylon, which is often used to make equipment housings nowadays, and is generally a plastic composed of polyamide resin and other materials. The manufacturing methods of this kind of resin manufacturers are quite diverse, which can be made not only by polycondensation of diamine and diacid, but also by ring-opening polymerization of lactam obtained by dehydration of amino acids. The equipment made of this kind of material has high strength, high wear resistance and high chemical resistance, so it can be applied to some harsh environments, achieve very good corrosion resistance, and is not interfered by external environmental factors. In addition, in terms of the use of ambient temperature, the application range is also very wide, and it can usually be applied between -40 degrees Celsius and +90 degrees Celsius, and can operate normally at 90 degrees Celsius. There will be no deformation, etc., and it can work normally at MINUS 40 degrees Celsius, without any influence on technical indicators, so it is very common in some construction sites. Of course, the equipment made of this material has a very obvious defect, which is that the feel of external light is not very comfortable, and it generally gives people a very hard feeling.The second material used to manufacture equipment today is nylon pa66, which is actually an upgrade of the first nylon belt material. This material is suitable for production equipment, and the requirements for injection molding process are quite strict, so the technical aspects of production using this material were certain requirements at that time. This kind of material is usually translucent, opaque, milky white crystalline polymer with strong ductility.
