The inner wall of the fixed box 7134 is installed with a second contact 71313, and the second contact 71313 is in contact with the first contact 71312.

When a short circuit occurs and the second power connection block 7115 moves downward, the conductive rod 7136 re-contacts the first power connection block 710 under the elastic force of the third spring 7137, so that the early warning device 7131 is re-connected to the circuit, and the early warning device 7131 is powered on to send an alarm to the staff, so that the staff can take timely measures to further protect the electronic components in the electrical switch cabinet.

[0023] Working principle: When the socket is directly installed, insert the power connection piece of the socket into the power connection slot 3 to complete the power connection; When it is necessary to connect with the electrical switch cabinet, the grafting plate 4 needs to be installed inside the dark box body 1, so that the power connection plate 5 on the grafting plate 4 is inserted into the power connection slot 3, and then the power cable and load cable components that need to be connected to the electrical switch cabinet are installed; Insert the cable component into the corresponding slot 704 on the installation head 703, so that the end of the cable component contacts the conductive surface 7119, and then turn the screw rod 706. Since the screw rod 706 is threadedly connected to the screw barrel 705, the installation head 703 is pushed to move upward, and a fixed pressure rod 71111 is fixedly installed on the inner top wall of the installation frame 701, so that the bottom end of the fixed pressure rod 71111 passes through the rod groove 71110 and enters the interior of the installation head 703, and the cable component is pressed and fixed, which is convenient for installation. At the same time, the first heat conduction block 71112 is in close contact with the cable component, which is convenient for heat conduction and temperature sensing of the cable component. Since the second power connection block 7115 is movably arranged, when the diameter of the cable component is small, the movement of the installation head 703 will not affect the contact between the second power connection block 7115 and the first power connection block 710; When the second power connection block 7115 contacts the first power connection block 710, the end of the pressure plate 7129 is located inside the empty slot 7121. At the same time, when the second power connection block 7115 moves upward, the push rod 7133 pushes the movable plate 71310 to move upward, and then the connecting rod 71311 drives the transverse block 7135 to move toward the side away from the first power connection block 710, so that the conductive rod 7136 is out of contact with the first power connection block 710, so that the early warning device 7131 is in a power-off state. When a short circuit occurs in the circuit, the current in the circuit suddenly increases, causing the temperature of the cable component to rise suddenly to a high level. Since the first heat-conducting block 71112 is in contact with the cable component, the heat is transferred to the sealed space above the piston 7125 through the heat-conducting rod 7123. At this time, the heat-expanding gas expands and pushes the piston 7125 to move downward, and then the pressure plate 7129 pushes the second power connection block 7115 to move downward, so that the second power connection block 7115 is disconnected from the first power connection block 710, and the power is cut off, thereby protecting the electronic components in the electrical switch cabinet. When the second power connection block 7115 moves downward, the transverse block 7135 moves toward the first power connection block 710 under the elastic force of the third spring 7137, so that the conductive rod 7136 contacts the first power connection block 710 again, and the corresponding early warning device 7131 is energized to send an alarm to the staff, so that the staff can take timely measures to further protect the electronic components in the electrical switch cabinet.
