[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-4 This utility model provides a technical solution: a cable management structure for a power distribution cabinet, comprising a positioning plate 1, a positioning bolt 2, a mounting window 3, a locking bolt 4, a locking nut 5, a mounting hole 6, a base plate 7, a track window 8, a cable management tube 9, an external thread 10, a fastening nut 11, a side hole 12, a compression bolt 13, a protective washer 14, and a protective ring 15. A positioning bolt 2 is installed through one end of the positioning plate 1, and a mounting window 3 is opened through the other side of the positioning plate 1. A locking bolt 4 is installed through the mounting window 3, and a lock is installed at the end of the locking bolt 4. A nut 5 and a locking bolt 4 pass through a mounting hole 6, which is located at the end of a substrate 7. The rear side of the end of the substrate 7 is attached to the front end of the other side of the positioning plate 1. A track window 8 is provided on the substrate 7, and a cable tie tube 9 is installed through the track window 8. An external thread 10 is provided on the outer wall of the front end of the cable tie tube 9, and a fastening nut 11 is installed on the external thread 10. A side hole 12 is provided on the side of the front end of the cable tie tube 9, and a compression bolt 13 is installed in the side hole 12. A protective pad 14 is fixed at the end of the compression bolt 13, and a protective ring 15 is fixed on the inner wall of the rear end of the cable tie tube 9.
[0016] The top view of the positioning plate 1 is "T" shaped. The positioning plate 1 is symmetrically distributed about the center of the base plate 7. The above structural design can provide a stable mounting base for the base plate 7 and enable the positioning plate 1 to be stably connected to the inner wall of the power distribution cabinet.
[0017] The locking bolt 4 is slidably connected to the mounting window 3. The mounting window 3 is vertically and equally spaced on the positioning plate 1. With the above structural design, the locking bolt 4 can slide vertically along the mounting window 3 with the base plate 7 to adjust the installation position.
[0018] Mounting holes 6 are symmetrically distributed about the center of substrate 7. Track windows 8 are horizontally and equally spaced on substrate 7. The above structural design enables substrate 7 to be installed stably. Track windows 8 facilitate the installation of multiple sets of wire harnesses 9 and make it convenient to arrange multiple sets of wire harnesses.
[0019] The outer wall of the cable harness tube 9 is tightly fitted to the inner wall of the track window 8. The cable harness tube 9 is set in an "L" shape. On the external thread 10 set on the outer wall of the front end of the cable harness tube 9, fastening nuts 11 are symmetrically installed about the vertical center of the substrate 7. The above structural design enables the cable harness tube 9 to be stably installed and quickly fixed by the fastening nuts 11, while also enabling the bending and guidance of the cable harness.
[0020] Side holes 12 are symmetrically installed on both sides of the front end of the cable harness tube 9. The side holes 12 are threadedly connected to the compression bolts 13. The thickness of the protective pad 14 fixed at the end of the compression bolts 13 and the thickness of the protective ring 15 fixed on the inner wall of the rear end of the cable harness tube 9 are both greater than 1 / 3 of the wall thickness of the cable harness tube 9. The above structural design can compress and position the front section of the cable harness passing through the cable harness tube 9 and prevent the rear end of the cable harness tube 9 from causing wear on the cable harness.
[0021] Working principle: During installation, the positioning plate 1 is installed on both sides of the inner wall of the distribution cabinet by the positioning bolts 2, and the locking bolts 4 are passed through the mounting window 3 at the appropriate position and through the mounting hole 6 at the end of the base plate 7. The locking nut 5 is installed on the end of the locking bolt 4 and tightened to fix the position of the base plate 7. The installation positions of the positioning plate 1 and the base plate 7 are both located behind the mounting mechanism of the switch, voltmeter, ammeter, electricity meter and other components in the distribution cabinet. First, install the switch, voltmeter, ammeter, electricity meter, and other components in place, then... Figure 3 The fastening nuts 11, symmetrically distributed on the external thread 10 at the front end of the central cable tube 9, are rotated away from the front and rear end faces of the substrate 7. The cable tube 9 is then slid horizontally along the track window 8 to align with the cable harness of the front component. The cable tube 9 is rotated according to the predetermined exit direction of the cable harness. Subsequently, the symmetrically distributed fastening nuts 11 are rotated to press and fix the cable harness away from the front and rear end faces of the substrate 7. The cable harness of the component is then inserted from the front section of the cable tube 9 and exited from the rear section of the cable tube 9. The symmetrically distributed pressing bolts 13, with protective pads 14, press and fix the cable harness. Finally, the cable harness is exited from the predetermined exit position of the distribution cabinet. This is the working principle of the cable harness structure used in the distribution cabinet.
