Industrial plugs are also often called industrial plugs, mainly because of the performance of this product, which is widely used in industrial environment at present, and the power supply is stable and reliable. 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. 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.Here, I'd like to introduce the three characteristics of the industrial plug and socket. I hope you can have a deeper understanding of the product after reading it.I. Mechanical propertiesThe reliability of all products in use largely depends on the mechanical properties of the products. For industrial plugs and sockets, the mechanical performance is actually the connection performance of products, that is, the force required when the plug is inserted into the socket and the force required when it is withdrawn. Generally, all plug and socket products have a certain pull-out force. Generally, the pull-out force of the plug will be less than the pull-out force, so it is called the maximum pull-out force and the minimum pull-out force.Industrial plugs and sockets are produced according to the standard seriously in this respect, so they have very stable reliability in connection.In addition, the loss caused by the unplugging force of this product is relatively low, so compared with some plugs and sockets in the past, the number of unplugging has obviously increased.II. PerformanceGenerally, the properties mentioned in products are contact resistance, insulation resistance and resistance. The lower the resistance of the product, the more stable it is, and it is a high-quality product. Industrial plugs and sockets in this area usually have a resistance of several milliohms to tens of milliohms, but they are very stable and will not affect the remaining current of the contact circuit when in use.In addition, the insulation resistance of the product has reached the standard, and the insulation performance of the product and external contact is relatively high. It also has very good electrical resistance, and its electrical strength is very high.III. Environmental performanceOf course, the environmental protection performance is also a very important product performance, especially in industrial plugs, because these products are used in some harsh industrial environments. In order to ensure the stable and reliable performance of these products in subsequent use, the manufacturers have made special treatment on these environmental protection performances, which will have an impact in high temperature, rain, vibration, impact and complex design.First of all, this product can be used to raise the ambient temperature, and now this kind of industrial plug and socket can be used in the range of MINUS 65℃ to MINUS 200℃, maintaining reliable operation.Secondly, the sealing performance of the product is improved, and some special materials are used in the outer shell of the product, so that the product will not be corroded or rusted due to some rainwater.
