[0059] It should be noted that the present invention is a junction box for power supply transfer. Before use, the device can be placed in a required location to achieve working conditions;

[0060] First, when two adjacent lines need to be connected, in the closed state of the junction box, the bidirectional screw rod 26 is rotated so that the two sliders 27 carry the two junction box bodies 3 to slide to the predetermined positions at both ends and then stop. At this time, the junction box is in a fully open state;

[0061] Then, according to the needs of the line connection direction, remove the bolt fastener 30, and then rotate the junction box body 3 clockwise or counterclockwise by 90 degrees as needed and then install the bolt fastener 30. In addition, if two adjacent lines are connected in the same line, the junction box body 3 does not need to be rotated.

[0062] According to the number of lines to be connected, the slider 3 40 is moved to the corresponding position so that the two adjacent rotating rollers 3 42 separate the lines to prevent them from being entangled, and then one end of the line is installed on the wiring terminal 4 to complete the connection between the one end of the line and the wiring terminal 4;

[0063] Then, the one-way screw rod 22 is rotated to move the baffle plate 24 downward until it fits with the outside of the wire and stops, and then the two-way screw rod 26 is rotated to move the two junction box bodies 3 toward the hollow box 10 until the junction box bodies 3 fit with both ends of the hollow box 10. At this time, the corresponding hollow block 29 is inserted into the small hole 20 of the hollow box 10;

[0064] Rotating the one-way screw rod 12 causes the slider 13 to move upward, and the slider 13 acts on the baffle 18 through the connecting arm 19 to move it, so that it moves with the conductive tube 2 17 toward the conductive plate 15, and is inserted into the circular hole of the insulating sleeve 6 to fit with the conductive plate 5. During the process, the conductive tube 2 17 pushes the two triangular blocks 24 open, and the triangular blocks 24 fit the outer side of the conductive tube 2 17 under the action of the spring 25. At this time, when the line is energized, the two adjacent lines are energized under the mutual connection of the conductive plate 15, the conductive tube 2 17, the conductive tube 16 and the conductive plate 2 15. If the line needs to be repaired, the position of the two conductive tubes 17 is adjusted by the one-way screw rod 12, so that the conductive tube 2 17 is disconnected from the conductive plate 15 at the corresponding position, so that the two adjacent lines are in a power-off state.
