Socket is a common special tool in people's daily life. The actual operation method is divided into industrial plug and household socket. 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. Embedded socket is embedded in an integrated communication cabinet, which provides DC basic power for communication and data equipment in the same cabinet. It has certain universality at the same time. 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. The application scenarios are different, and there are great differences in design and function. Everyone knows well about electrical outlets, but the actual operation of industrial production is more effective in design. Sometimes, the output power design is carried out according to common scenes, including the firmness of jacks and relative regulations. In order to avoid inserting other power sources, some industrial plugs will continue to be specially designed, so as to have certain maintenance effect and prevent random application of high-power products. In addition, general industrial plugs are also equipped with connectors produced in industry, that is, special connectors. Both parties must be connected according to RF connectors, so that funds can be invested in all normal applications. In addition to the load level, industrial plugs will also appear in some unique areas. For example, the specifications of dual-core or triple-core, and the different current specifications of their applications, can also be used in related scenarios. When using sockets, products inspected by relevant departments are generally selected to make the quality more reliable. In addition, when installing the industrial plug, it is necessary to ensure that the rated current exceeds 1.25 times of the known current to prevent the industrial plug from being damaged due to excessive current.
