[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Although exemplary embodiments are disclosed in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to facilitate a more thorough understanding of the present utility model and to fully convey the concept of the present utility model to those skilled in the art.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] like Figures 1-4As shown, this embodiment provides a power distribution cabinet 100, including a cabinet body and a cabinet door 30 connected to the cabinet body via a hinge connector 20. A sealing strip 301 is installed on the end face of the cabinet door 30 near the electronic components by means of adhesive or other fixed connection. The sealing strip 301 is made of EPDM rubber, which gives it excellent heat aging resistance.

[0033] Furthermore, the sealing strip 301 has a groove along the circumference of the cabinet door 30, so that the cross-section of the sealing strip 301 is trapezoidal. The height of the sealing strip 301 is 20mm and the length is 17mm; thus, it can withstand long-term friction, extend its service life, and reduce the frequency of replacement.

[0034] Furthermore, an mounting plate 40 is fixedly installed inside the cabinet cavity by fastening bolts, and electronic components 70 are provided on the mounting plate 40, and the electronic components 70 are detachably connected to the mounting plate 40.

[0035] In existing cabling systems, the moving parts of the cable cannot be fixed during installation. Fixing them prevents the distribution and absorption of bending stress, leading to stress concentration at the fixed location. However, leaving them unfixed results in the cable being too loose, causing it to tangle. To solve these technical problems, please refer to [link to relevant documentation]. Figure 1 As shown, a connecting rod 10 is fixedly installed on the inner wall of the cabinet near the cable laying end (cable moving end) by fastening bolts, and at least one set of cable wiring mechanism is provided on the connecting rod 10. The cable wiring mechanism includes at least one set of connecting plates, and the connecting plate 601 is welded to the connecting rod 10. The ear plate 603 is fixedly installed on the connecting rod 10 by fastening bolt 603.

[0036] Furthermore, the connecting plate 605 is fixedly connected to the ear plate 603 by fastening bolts, and a threaded hole is provided on the transverse end face of the connecting plate 605. A screw 606 for adjusting the height is provided in the threaded hole, and an arc plate 607 is fixedly connected to it by the screw. By rotating the screw, the screw can be adjusted to screw into or out of the threaded hole, thereby adjusting the height of the arc plate.

[0037] Furthermore, the screw at the end away from the arc plate 607 passes through the threaded hole of the connecting plate 605 and is fixed in position by the fastener 604.

[0038] When using the product, if the height of the curved plate needs to be adjusted, simply rotate the screw to adjust the position of the curved plate. Once adjusted to the desired position, tighten the fastener 604 to achieve the desired height adjustment.

[0039] In practical applications, first, fix the cable reel on the cabinet, then adjust the moving distance of the arc plate. The distance should be 20-30 times the cable diameter, and the moving point of the cable should be 20-30 times the distance of the cable reel end (initial end). Pull out the cable and bend the end of the cable close to the arc plate so that the cable is in contact with the outer wall of the arc plate 607. When bending, pay attention to avoid bending the cable at 90°.

[0040] Furthermore, at least one set of wiring boards 50 is provided on the mounting plate 40 located away from the wiring mechanism, and at least one set of wire inlet grooves 501 are provided on the wiring board 50, and a groove 503 for accommodating the clamping member 504 is provided on the side end face of the wiring board.

[0041] In this embodiment, the cable reel is fixedly installed on the cabinet, and then the moving distance of the arc plate is adjusted. The distance should be selected to meet the requirement that the moving point of the cable is 20-30 times the cable diameter from the cable reel end (initial end). The cable is pulled out and the end of the cable close to the arc plate is bent so that the cable is in contact with the outer wall of the arc plate 607. Then the other end of the cable passes through the through slot at the top of the cable inlet groove 501 and extends into the clamping member 504. The clamping member 504 clamps the middle part of the cable.

[0042] Furthermore, the clamping member 504 has a connecting groove 505 inside, and the center line of the wire inlet groove 501 is perpendicular to the center line of the clamping member 504.

[0043] Furthermore, the clamping member 504 is made of an elastic material.

[0044] In this embodiment, by adding a wiring mechanism and a wiring board, and utilizing an arc-shaped plate, the cable laying end is made...

[0045] The cable is attached to the outer wall of the arc plate 607, and care should be taken to avoid bending the cable at 90° when bending it, which can effectively reduce stress and also effectively plan the cable path. The other end of the cable passes through the cable inlet groove 501 and extends into the clamping member 504. The clamping member 504 clamps the tail of the cable, thereby improving the clamping of the cable and preventing the cable from being too loose and causing the cable to become tangled.

[0046] In practical applications, the overall radius of the cable should be kept as large as possible. The bending radius of a cable refers to the maximum bending tolerance it can withstand during normal operation. Assuming the cable's outer diameter is X, its bending radius must be greater than 10~12X. Please refer to [link / reference]. Figure 4As shown, when the cable passes through the through groove at the top of the clamp 504, in order to maximize the bending radius of the cable, the cross-section of the connecting groove is T-shaped. The distance between the top end face of the connecting groove 505 near the inlet groove 501 and the bottom end face of the connecting groove away from the inlet groove 501 is L, and L is 10-40mm.

[0047] Furthermore, the connecting groove 505 is a through groove.

[0048] In this embodiment, the cable passes through the through slot at the top of the clamp 504, and one end of the cable abuts against the top of the inner wall of the clamp. Then the cable is bent so that the other end of the cable abuts against the bottom of the clamp and passes through the front opening of the through slot 505 of the clamp, and is connected to the electronic components.

[0049] In this embodiment, when the cable needs to be bent multiple times, in order to ensure the safe use of the cable, the connecting groove 505 is reasonably set to increase the bending radius of the cable, thereby reducing the risk of cable breakage or short circuit.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not restrictive. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
