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. 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 normally open switch of the electromagnetic switch is arranged on the power line; and the normally open switch of the electromagnetic switch is connected with the jack. 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. I. Safety and reliability As we all know, plugs and sockets are products related to electricity safety, so there are certain requirements for product quality, not to mention products used in industry. In all aspects, manufacturers are thoughtful, precise design, to ensure the safety of products in use. 1. First of all, in order to help the operators not to use the product wrongly, the shell color of industrial plug products is designed according to the rated voltage represented by the product. For example, the blue shell represents 220V, while the red shell represents 380V, so the rated voltage represented by the product can be seen at a glance on the shell. To a great extent, it solves the problem that some plugs and sockets in the past often confuse the product voltage and use it wrongly. 2. Secondly, when the product models and specifications are different, the diameter, number of rods and grounding position of grounding contacts are also very different, so even if you want to use products for mismatch, it is impossible, because under such a design, only products with the same specifications can be inserted for operation, which completely solves the previous errors caused by faults and hazards. 3. Industrial Plugs and Sockets This product is specially designed to prevent electric shock for the safety of electricity use, that is, the grounding pole socket of the product is designed to be longer than that of the phase pole and the neutral pole socket, so that it can be ensured that the product will be connected to the prefecture level first, then connected to the phase pole, and the same is true when it is pulled out, and the earth pole will be pulled out last, thus ensuring the safety of the product. 4. There are many kinds of industrial plugs, from the old ip44 splash-proof type to the more common ip67 immersion-proof type. However, no matter which type, this series of plug and socket products have high protection performance, so as to ensure that the operator will not directly contact the live parts when using the products and ensure the safety of use. 5. The industrial plug is specially designed, and the top of the socket is provided with an elastic ferrule, which ensures the close contact and good conductivity after being inserted into the industrial plug, so that the product can not only keep more reliable operation, but also prolong the service life of the product correspondingly. 6. Besides sockets, industrial plugs also have a special design, that is, the plugs are equipped with retaining devices, so that the plugs and sockets can be plugged tightly during the use of the products, and the situation of falling off will not occur at all, thus greatly improving the reliability in use.
