Description

Technical Field

[0001] This utility model belongs to the field of power distribution cabinet wiring technology, specifically relating to a hidden wiring mechanism for power distribution cabinets. Background Technology

[0002] In power distribution systems, distribution cabinets are the core equipment for power distribution and control. The installation of their internal electronic components and the rationality of their cable routing directly affect the equipment's operational stability, ease of maintenance, and space utilization. Currently, traditional distribution cabinets often use exposed or simple cable bundling methods for internal wiring, resulting in cables being randomly distributed inside the cabinet. This not only leads to a cluttered and disorganized interior, increasing the risk of mutual interference between lines, but also easily causes safety hazards such as short circuits due to cable entanglement and compression.

[0003] Meanwhile, the installation and wiring of electronic components in existing power distribution cabinets are mostly completed inside the cabinet. Due to the limited space inside the cabinet, it is inconvenient for installers to operate, which not only prolongs the construction period but also makes it difficult to ensure the standardization of wiring.

[0004] In addition, traditional cabling structures lack effective cable fixing and classification mechanisms. When it is necessary to inspect or replace the components inside the cabinet, the messy cables will increase the difficulty of troubleshooting and may accidentally touch other lines during operation, affecting the normal operation of the equipment.

[0005] In addition, although some distribution cabinets have attempted to use simple cable trays for cable storage, the cable trays are fixed in position and cannot be flexibly adjusted according to the installation position of electronic components, resulting in poor adaptability. Furthermore, the cables lack effective restraint within the cable trays and are prone to displacement due to vibration and other factors, which may lead to problems such as poor contact after long-term use.

[0006] Therefore, a concealed wiring mechanism for power distribution cabinets is provided to solve the above-mentioned technical problems. Utility Model Content

[0007] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a concealed wiring mechanism for power distribution cabinets, which solves the problems of exposed and messy cables in power distribution cabinets that easily cause safety hazards, inconvenient installation and maintenance, poor adaptability of wiring structure and insufficient cable fixing stability in the prior art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A concealed wiring mechanism for a power distribution cabinet includes two cabinet connecting plates with hooks and a mounting plate for installing electronic components inside the cabinet. The mounting plate is detachably installed between the two cabinet connecting plates, and multiple mounting holes and multiple wire holes are provided through the front and rear surfaces of the mounting plate. Multiple slides are adjustablely installed on the rear surface of the mounting plate, and multiple self-locking carrier blocks with adjustable positions are installed on the outer surface of the slides. Hollow wire blocks with adjustable orientation are installed on the front surface of each self-locking carrier block.

[0010] In the above technical solution, L-shaped blocks are fixedly installed on the rear surfaces of the upper and lower ends of the slide, and the slide is horizontally slidably mounted on the rear surface of the mounting plate through the L-shaped blocks at both ends. A tightening bolt is threaded through the lower surface of the lower L-shaped block.

[0011] In the above technical solution, the slide is I-shaped, and multiple triangular notches are equidistantly provided on one side of the slide. The self-locking carrier block is slidably mounted on the outer surface of the slide, and a sliding groove is provided through the self-locking carrier block. A J-shaped locking block is slidably installed through the sliding groove. A spring is fixedly installed between the J-shaped locking block and the self-locking carrier block, and the J-shaped locking block is engaged in the corresponding triangular notch to fix the self-locking carrier block and the slide.

[0012] In the above technical solution, a miniature internal rotor bearing is embedded in the side of the hollow conductor block near the self-locking carrier block. A rotating shaft is fixedly installed inside the miniature internal rotor bearing. The end of the rotating shaft away from the miniature internal rotor bearing is fixedly installed on the outer surface of the self-locking carrier block. A plurality of damping pads are sleeved on the outer surface of the rotating shaft. The outer surfaces of the two outer damping pads are respectively in contact with the outer surfaces of the self-locking carrier block and the hollow conductor block.

[0013] In the above technical solution, a wire sleeve is rotatably installed in the inner cavity of the hollow conductor block, and a wire bundle elastic clip is fixedly installed at any end of the wire sleeve.

[0014] In the above technical solution, the cabinet connecting plate has recessed holes at the four corners on the side near the mounting plate. Four L-shaped brackets are symmetrically distributed and fixedly installed on the side of the cabinet connecting plate near the mounting plate. The mounting plate is H-shaped, and four hanging interfaces are symmetrically opened on the side of the mounting plate near the cabinet connecting plate. The L-shaped brackets are hung in the corresponding hanging interfaces.

[0015] The concealed wiring mechanism for power distribution cabinets of this utility model has the following advantages compared with the prior art:

[0016] This utility model features an H-shaped mounting plate with mounting holes and wire-passing holes. The L-shaped bracket of the cabinet connecting plate is connected to the mounting plate's hanging interface, allowing cables to be stored at the rear of the mounting plate. This achieves concealed wiring, solves the problem of exposed and messy cables, and reduces safety hazards. At the same time, the mounting plate is detachable, facilitating the pre-installation and wiring of electronic components outside the cabinet, thus improving the convenience of installation and maintenance.

[0017] By setting a slide that can slide laterally and be fixed by an L-shaped stop and a locking bolt on the rear surface of the mounting plate, and a self-locking carrier that can slide vertically on the slide and is self-locked by a J-shaped locking block, a spring and a triangular notch, the flexible adjustment of the wiring position is realized, which solves the problem of poor adaptability of traditional wiring structures and meets different wiring needs.

[0018] By setting a rotatable hollow conductor block with a miniature internal rotor bearing, a shaft, and damping pads on a self-locking carrier block, and a wire sleeve with a wire bundle elastic clip inside the hollow conductor block, flexible adjustment and stable fixation of the cable routing are achieved, solving the problem of insufficient cable fixation stability and ensuring the stability and standardization of the cable after wiring.
