Description

Technical Field

[0001] The utility model belongs to the technical field of cable fixing, and particularly relates to a grounding cable locker used for cable fixing. Background Art

[0002] The Chinese utility model patent with publication number CN206947920U discloses an OPGW floor-standing cable box, including a box body, wherein a plurality of horizontal mounting plates are arranged in the box body, and vertical mounting plates are arranged between the horizontal mounting plates. A first cable rack capable of winding the OPGW optical cable is arranged on one side of the horizontal mounting plate, and a second cable rack capable of winding the guide optical cable is arranged on the other side; a joint box is arranged on the vertical mounting plate, and the OPGW optical cable and the guide optical cable are fused in the joint box; a high-voltage disconnector is arranged on the bottom horizontal mounting plate, and the OPGW optical cable is connected to the incoming line end of the high-voltage disconnector through a grounding wire before winding to the first cable rack, and from the first cable rack winding to the junction box, and the outgoing line end of the high-voltage disconnector is connected to the external substation grounding grid. The cable box described in the utility model adopts a three-point grounding technology to ensure reliable grounding of the OPGW optical cable.

[0003] The above-mentioned prior art discloses a cable lock card, which is used to fix the OPGW optical cable. The cable lock card is made of aluminum alloy and is provided with a grounding point. The grounding wire is crimped and connected to the incoming line end of the high-voltage disconnector to complete effective grounding. The cable lock card is used to fix the OPGW optical cable. Because the clamping force is limited, the clamping force is limited when clamping the OPGW optical cable. When the remaining cable box shakes, the fixed OPGW optical cable is easy to slide and dislocate. Forced locking will also squeeze and damage the cable. In addition, the cable lock card of the above-mentioned prior art has only one wire groove. When multiple groups of OPGW optical cables need to be fixed, multiple groups of cable lock cards need to be set up separately, which is time-consuming and labor-intensive. Utility Model Content

One end of the guide rod is fixed to the kneading rod, and the other end passes through the bending part, and the bending part is provided with a guide hole for the guide rod to penetrate.

[0009] Furthermore, in order to provide anti-slip and pressure reduction effects when the kneading rod is pressed and improve the comfort of use, the kneading rod is made of flexible rubber.

[0010] Furthermore, in order to make the ratchet move more smoothly and to increase the strength of its limiting ratchet, the base is provided with a strip opening on the side of each ratchet to form a strip sliding hole.

Because of the establishment of the ratchet and the ratchet and ratchet principle (the existing principle, so it will not be repeated), the deflection frame can only deflect in one direction to prevent the clamping pre-tightening force between the first cable seat and the second cable seat from loosening, and as the deflection frame deflects toward the base side, the clamping between the first cable seat and the second cable seat will only become tighter and tighter, and because the bent part is elastically clamped, forced clamping will not occur, and the damage to the cable is small.

[0015] ② The number of clamped cables is not single: through the establishment of the first cable seat and the second cable seat, more than one set of cable grooves can be set on the first cable seat and the second cable seat, and the cables that can be fixed are not limited to one.
