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. 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. The handle was not completely fixed on the main body when the portable industrial plug product was delivered for the first time, so the working equipment could not be used during the first installation. Just press the spring plate with a screwdriver or other tools to loosen and install it. There is no need for screw connection and peeling on the product. When using electrode terminals with different colors, different stages can be quickly distinguished by using different colors, making the connection process easier and faster. Using the same way of installing wires and electrode terminals, the construction time is shortened and the work efficiency is improved. The external cable locking nut, cable sealing ring and cable self-tightening ring apron can be integrated. Its main feature is that it can be easily tightened manually without using any tools. This structure can prevent the nut from falling off accidentally or due to vibration or mechanical pressure. Ip44 industrial plug is provided with fins on the opening cover, which makes it easier to open the cover when the plug is inserted, ensuring simple and quick operation. In fact, the mobile socket and plug produced are the same, and the fixed hook is adopted in the design case, so that the product can be hung in any environment.
