Many friends should know something about industrial plugs, but what parts of industrial plugs do we know? When can industrial plug failure accurately determine the location of the problem? The structure of industrial plug is introduced. 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. The power socket has a seat 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 applicable to industry, generally divided into 3-core, 4-core, 5-core, etc. Current is generally divided into 16A, 32A, 63A, 125A, 250A, 420A, etc. The protection level can be divided into IP44 and IP67, which are relatively conventional. Generally, it is used with industrial sockets and connectors. Industrial plugs generally consist of housing, bayonet ring, snap seal ring, latch, handle, handle seal ring, cable rack, cable seal ring, metal washer, screw gland, screw, etc. See the following figure for details.1. Industrial plug shellThe function of the shell is mainly to protect other internal parts and connect the loading bolt with the handle, but the most important thing is the function of sealing and waterproofing. The diameter, bolt seat and fast size of the shell must meet the requirements of national GB/T11919-2001 standard.The surface of the handle fixing block is designed with anti-slip stripes, and the tail of the handle is provided with cable entrance holes. In order to meet the requirements of waterproof and anti-immersion, commonly used industrial plugs are composed of threaded sealing ring, metal gasket and rubber sealing ring. There are two types of housings: two-piece and one-piece, one of which is basically the first generation product, while the two-piece front housing and the rear part of the latch seat are handles. Shells are usually made of thermoplastic, and the colors of pc and pa shells usually represent different voltages.2. As an important structure of industrial plugs, the bayonet ring strictly meets the requirements of gb/t11919-2001. The inner hole of the bayonet ring can be sleeved on the plug shell to rotate freely, and has a certain anti-falling function. Usually, anti-stripping structure is adopted to ensure that the bayonet ring will not fall off the housing.3. The function of the sealing ring is waterproof. Water is placed into the interior of the industrial plug through the gap between the shell and various parts. The sealing ring is generally made of elastic material or ordinary rubber, and it can be divided into three types according to different parts of use:(1) The utility model relates to a buckle sealing ring, which is mainly used for sealing the connection surface between industrial plugs and industrial plugs.(2) Handle sealing ring, mainly for waterproof treatment between industrial plug shell and handle;③ Cable sealing ring is used to seal and waterproof the end of industrial plug after connecting cables.4. Through the assembly of the above structures, the industrial plugs we use are made. The principle of industrial plugs is to adopt some personalized design institutions to achieve the purpose of waterproofing. Let's have a deep understanding of the characteristics of industrial plugs. First of all, industrial plugs are waterproof. We can choose different levels of industrial plugs according to our actual needs. After that, it has strong dustproof performance, and industrial plugs can be used normally in some dusty and serious areas; There is also the function of splash-proof, of course, even the water can be splash-proof, let alone; Because the shell material is made of high-quality engineering plastics, it has strong anti-corrosion ability, and can withstand long-term sunlight and be used normally.
