Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a cable fixing structure of a high-voltage power distribution cabinet. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box) and metering cabinet (box). It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is suitable for occasions with relatively dispersed loads and fewer circuits; the motor control center is used in occasions with concentrated loads and more circuits. They distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. Among them, the high-voltage distribution cabinet is a type of distribution cabinet.

[0003] At present, when high-voltage distribution cabinets are in use, a large number of electronic components are installed inside them. However, when some high-voltage distribution cabinets are in use, the cables of the electronic components are placed or hidden behind the distribution cabinets. When the electronic components are inspected and repaired, the cables need to be combed and disassembled. At the same time, the cables are entangled with each other, which may reduce the service life of the cables. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 As shown, a cable fixing structure of a high-voltage power distribution cabinet includes a power distribution cabinet body 1, and also includes:

[0021] A connecting frame 2 is arranged on the top of the power distribution cabinet body 1, and a positioning bolt 3 is arranged inside the connecting frame 2;

[0022] The fixing assembly 4 is arranged on the rear surface of the power distribution cabinet body 1, and the fixing assembly 4 includes a fixing box 41 arranged on the rear surface of the power distribution cabinet body 1, a threading tube 42 is slidably connected inside the fixing box 41, a rotating tube 43 is rotatably connected outside the threading tube 42, and a screw mechanism 44 is arranged inside the fixing box 41.

[0023] refer to Figure 2 and Figure 3 As shown, the rotating tube 43 includes a moving rod 5 threadedly connected to the inside for adjustment, and the moving rod 5 includes a moving ring 6 fixedly connected to the bottom.

[0024] The moving ring 6 includes an elastic ring 7 disposed inside for protecting the cable casing, and the elastic ring 7 includes a rough block 8 disposed inside.

[0025] It should be noted that when the staff needs to fix the cable, they first install the fixing boxes 41 of different sizes according to the specifications of the cable, first install the connecting frame 2 through the positioning bolt 3, and after the installation is completed, pull the positioning rod 12 to move the positioning rod 12 to the specified position, and then start the screw mechanism 44 to operate. When the screw mechanism 44 operates, it can drive the threading tube 42 to move, and then adjust the position of the threading tube 42. After the threading tube 42 moves to the specified position, the staff passes the cable through the threading tube 42, so that the cable One end of the cable is connected to the electronic component, and then the length of the cable is adjusted so that the cable is not too tight or too loose. Then the rotating tube 43 is rotated, and the rotating tube 43 can drive the moving rod 5 to move, so that the inner circle of the elastic ring 7 can contact the outer part of the cable. At the same time, the rough block 8 can make a certain gap between the outer side of the cable and the inner circle of the elastic ring 7 to facilitate air flow. The positioning rod 12 is loosened so that the positioning rod 12 enters the interior of the threading tube 42, and the cable can be positioned and fixed.

[0026] refer to Figure 1 and Figure 2 As shown, the screw mechanism 44 includes a connecting block 9 arranged on the outside for driving the threading tube 42 to move, and the fixing box 41 includes a side tube 10 arranged on the rear surface.

[0027] The side tube 10 includes a spring 11 welded to one side of the inner wall, and a positioning rod 12 slidably connected to the inside.

[0028] One end of the spring 11 is welded to the outer side of the positioning rod 12 . A positioning hole 13 is provided inside the threading tube 42 . The inner wall of the positioning hole 13 is slidably connected to the outer side of the positioning rod 12 .

[0029] It should be noted that when the staff needs to adjust the position of the wire threading tube 42 according to the cable, first the screw mechanism 44 starts to operate. When the screw mechanism 44 operates, it can drive the connecting block 9 to move, and then the connecting block 9 drives the wire threading tube 42 to move. At the same time, a bracket is fixedly connected to the outside of the wire threading tube 42, and the bracket is fixedly connected to one end of the side tube 10, and then the wire threading tube 42 can drive the side tube 10 to move through the bracket. After one end of the cable is connected to the electronic component, the positioning rod 12 is released, and under the elastic force of the spring 11, the positioning rod 12 enters the interior of the positioning hole 13, so that one end of the positioning rod 12 can squeeze the cable inside the wire threading tube 42 to position the cable.

[0030] refer to Figure 2As shown, a sliding groove 14 for the movement of the wire tube 42 is provided inside the fixed box 41, a ventilation window 15 for heat dissipation of the cable is provided inside the fixed box 41, and a fixing block 16 for maintaining stable movement is fixedly connected to the outer side of the wire tube 42.

[0031] It should be noted that the staff can adjust the position of the wire tube 42 according to the position of the cable, so that the cable can pass through the wire tube 42 smoothly, so that the cable will not be too bent, and the cable can be protected to a certain extent. At the same time, under the action of the ventilation window 15, the outside air can flow smoothly inside the fixed box 41, thereby preventing the temperature inside the fixed box 41 from being too high and affecting the normal operation of the cable.

[0032] Working principle: When the staff needs to fix the cables of the electronic components inside the distribution cabinet body 1, first push the positioning rod 12 to compress the spring 11, then pass the cable through the threading tube 42, and then connect one end of the cable to the electronic component normally. After the connection is completed, pull the cable to make the cable in a slightly tight state, and then the staff rotates the rotating tube 43. When the rotating tube 43 rotates, it can drive the moving rod 5 to move, and then the moving rod 5 can drive the moving ring 6 to move. After the moving ring 6 moves to the specified position, the inner circle of the elastic ring 7 fits with the outer part of the cable, and at the same time, the rough block 8, there is a certain gap between the cable and the elastic ring 7 to facilitate air flow. At the same time, the staff loosens the positioning rod 12, and under the elastic force of the spring 11, the positioning rod 12 can enter the interior of the positioning hole 13, and then one end of the positioning rod 12 can squeeze the cable inside the threading tube 42, and then the positioning rod 12 can position and clamp the cable inside the threading tube 42, which is convenient for the staff to position the cables separately and to disassemble and assemble the cables. At the same time, under the action of the screw mechanism 44, the position of the threading tube 42 can be adjusted so that the cable can directly pass through the threading tube 42.
