[0024] Specifically, as Figure 1 shown, when in use, the wire connected to the device can be inserted into the interior of the wire groove 11 along the wire hole 15 at the center position of the lead plate 14. After the wire contacts the wire post 12 and the wiring board 13 on the inner side of the wire groove 11, the fixing bolt 18 can be rotated. The fixing bolt 18 pushes the pressure rod 17 to move, presses the wire against the inner side of the wire groove 11 for fixation, and then the wire connection operation can be completed;

[0025] A position adjustment component is provided at the tail end of the junction box 5. The position adjustment component includes an adjustment table 21, a knob 22, a lead screw 23, a nut 24, a slider 25, and a chute 26. An adjustment table 21 is provided at the tail end of the junction box 5. A knob 22 is movably installed at the bottom end of the adjustment table 21. The top end of the knob 22 extends into the interior of the adjustment table 21. A lead screw 23 is installed at the top end of the knob 22.

[0029] Working principle: When in use, first install the junction box 5 through bolts. The junction box 5 is installed on the door frame for use. Then, tear off the release paper 29 on the back of the magnetic box 1, and bond the magnetic box 1 to the door body with the help of the foam adhesive 28 for pre-installation. When the door body is in the closed state, after the magnetic box 1 is aligned with the junction box 5 on the door frame, the position of the magnetic box 1 can be fixed through bolts. If the positions are slightly misaligned with each other, the operator can directly rotate the knob 22 below the adjustment table 21 on the back of the junction box 5. As the knob 22 rotates, the screw rod 23 inside the adjustment table 21 can be driven to rotate. The screw sleeve 24 can move up and down along the screw rod 23, and drive the front-end junction box 5 to move up and down through the slider 25, driving the junction box 5 to be aligned with the magnetic box 1. Finally, the circuit connection can be carried out. The circuit connected to the device can be inserted into the inside of the wire groove 11 along the wire hole 15 at the center of the lead plate 14. After the circuit contacts the wire post 12 and the wiring board 13 inside the wire groove 11, the fixing bolt 18 can be rotated. The fixing bolt 18 pushes the pressure rod 17 to move, pressing the circuit against the inside of the wire groove 11 for fixation to prevent the circuit from falling off. In this way, the connection operation between the circuit and the junction box 5 is completed.
