[0041] The following is combined with Figure 1-4 This application is described in further detail.

[0042] The present application embodiment discloses a cable fixer. Figure 1 and Figure 2 The cable holder includes a bottom plate 1, a T-shaped plate 2 and two side baffles 3. The T-shaped plate 2 and the side baffles 3 are vertically connected to the same surface of the bottom plate 1. The T-shaped plate 2 includes a first plate 21 and a second plate 22 that are perpendicular to each other. The two side baffles 3 are respectively located on opposite sides of the second plate 22. The side baffles 3 are arranged parallel to the second plate 22 and spaced apart. The two side baffles 3 and the T-shaped plate 2 form two L-shaped cable grooves for power cables to be inserted into.

[0043] The beneficial technical effects of the cable holder of the embodiment of the present application are roughly as follows:

[0044] The two L-shaped cable grooves formed by the bottom plate 1, the T-shaped plate 2 and the two side baffles 3 can clamp and fix the two power cables, effectively preventing the power cables from twisting and shaking frequently during use, which is not only conducive to the stable installation of the power wires, but also the surface of the power wires is easily damaged due to repeated friction, thereby greatly improving the service life of the power wires.

[0045] In this embodiment, a blocking portion 4 is provided on the side of the side baffle plate 3 close to the second plate 22, and the blocking portion 4 is located inside the L-shaped wire groove. The blocking portion 4 is used to isolate the power cable in the L-shaped wire groove, wherein the blocking portion 4 is located on the outer side of the side baffle plate 3 away from the first plate 21.

The fixing plate 5 is provided with a hook groove 51. The first hook 61 is clamped on the hook groove 51. The fixing plate 5 is vertically connected to the bottom plate 1 and the side baffle 3 at the same time.

[0050] The fixing plate 5 and the wire clamping member 6 designed above have a simple structure and are easy to manufacture, and can further improve the stability of the power cable. Moreover, the fixing plate 5 can also greatly improve the structural firmness of the cable holder 203 .

[0051] In order to facilitate the bending and arrangement of the power cable in the L-shaped cable slot, a circular arc chamfer 23 is provided at the connection between the first plate 21 and the second plate 22 to prevent the power cable from breaking due to bending transition in the L-shaped cable slot.
