[0026] The load-bearing frame 143 contacts the combing frame 145, the load-bearing frame 143 contacts the T-shaped rod 7, and the combing frame 145 contacts the inner wall of the cabinet 1. By combing the connecting wires inside the cabinet 1, the electromagnetic coupling between different connecting wires can be reduced, crosstalk can be reduced, and the stability of the signal can be enhanced.

[0027] The protection device includes a guide tube 151, a linkage disk 152, a support disk 153, a support rod 154, a fixing frame 155, a power-off button 156 and a wire rope 157.

[0029] When the present embodiment is working, the T-shaped rod 7 moves toward the direction close to the protection rod 8, contacts the load-bearing frame 143 and squeezes the load-bearing frame 143. The load-bearing frame 143 is squeezed by the T-shaped rod 7 and moves in the direction away from the free end of the elastic telescopic rod 144. The load-bearing frame 143 moves in the direction away from the free end of the elastic telescopic rod 144 to drive the load-bearing rod 142 to move. The load-bearing rod 142 moves to squeeze the combing spring 146. The combing spring 146 is squeezed by the load-bearing rod 142 to produce deformation and accumulate force. At the same time, the load-bearing frame 143 moves in the direction away from the free end of the elastic telescopic rod 144 and breaks away from the contact with the combing frame 145. After frame 143 is out of contact with combing frame 145, the squeezing and fixing of the connecting wire is released. When the T-shaped rod 7 moves in the direction away from the protective rod 8 to reset, the T-shaped rod 7 moves in the direction away from the protective rod 8 to be out of contact with the load-bearing frame 143. After the load-bearing frame 143 is out of contact with the T-shaped rod 7, the load-bearing rod 142 moves toward the combing frame 145 under the elastic force of the combing spring 146. The load-bearing rod 142 moves toward the combing frame 145, driving the load-bearing frame 143 to move. The load-bearing frame 143 moves and contacts with the combing frame 145 and cooperates with the load-bearing groove and the combing groove to comb and fix the connecting wire inside the cabinet 1.

[0030] The load-bearing frame 143 moves in a direction away from the free end of the elastic telescopic rod 144, driving the load-bearing rod 142 to move. The movement of the load-bearing rod 142 drives the linkage plate 147 to move in a direction away from the free end of the elastic telescopic rod 144. The linkage plate 147 moves in a direction away from the free end of the elastic telescopic rod 144, contacts with the linkage disk 152 and squeezes the linkage disk 152. The linkage disk 152 is squeezed by the linkage plate 147 and moves in a direction away from the load-bearing plate 141. The linkage disk 152 moves in a direction away from the load-bearing plate 141 to squeeze the No. 1 spring. The No. 1 spring is squeezed by the linkage disk 152. The extrusion produces deformation and accumulates force, and at the same time the linkage disk 152 moves in the direction away from the load-bearing plate 141, driving the wire rope 157 to move. The movement of the wire rope 157 causes the support disk 153 to move toward the power-off button 156 under the elastic force of the support spring 158. The support disk 153 moves toward the power-off button 156, driving the support rod 154 to move. The support rod 154 moves and contacts the maintenance slot to limit the power-off button 156. The power-off button 156 is limited by the support rod 154, so that the power-off button 156 cannot be pressed when the electrical equipment inside the cabinet 1 is being repaired.
