Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for power distribution switchgear, specifically a wire embedding device for power distribution switchgear. Background Technology

[0002] As is well known, power distribution switchgear is the core equipment for power distribution, control and protection in power systems. It requires a large number of cables of different specifications and purposes (such as power lines, signal lines, etc.) to be laid inside. The orderly fixing and reasonable layout of the cables directly affect the operational stability and maintenance convenience of the switchgear.

[0003] Currently, cables in power distribution switch cabinets are mostly secured using methods such as cable ties, clips, or simple brackets, which have the following drawbacks: Existing fixed structures are mostly fixed or can only achieve rough adjustment in a single dimension (such as height), which cannot flexibly adjust the fixed angle according to the needs of cable routing. They are difficult to adapt to the complex spatial layout inside the switch cabinet and are prone to excessive bending or stretching of cables.

[0004] The cable needs to be inserted through the end of the fixing hole. For long-distance or multi-turn cables, the installation process is time-consuming and laborious, and the insulation layer is easily worn due to dragging.

[0005] When multiple cables share the same fixed structure, they are prone to tangling and squeezing, which not only affects heat dissipation but also makes it difficult to quickly identify the target cable during later maintenance, reducing maintenance efficiency.

[0006] In some adjustable structures, the spring used for reset is prone to twisting and deformation due to rotation during the adjustment process, which can lead to decreased elasticity or failure, affecting the reliability of the fixation and shortening the service life of the device.

[0007] The sharp corners or rigid contacts of fixed structures can easily cause stress concentration at the bends of cables, which may lead to cracks in the insulation layer after long-term use, posing a risk of leakage.

[0008] Therefore, there is an urgent need for a buried cable device that can flexibly adjust the height and angle, is easy to install, can independently manage multiple cables, and can protect cables and components, in order to solve the problems existing in the current technology. Utility Model Content

[0009] Technical problems to be solved In view of the shortcomings of existing cable fixing devices for power distribution switchgear, such as insufficient adjustment flexibility, inconvenience in cable laying, and chaotic management of multiple cables, this utility model provides a cable burying device for power distribution switchgear.

[0010] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a wiring device for a power distribution switchgear, comprising a mounting plate, an mounting mechanism and a wiring mechanism on the mounting plate, the wiring mechanism comprising a threaded groove and a threaded post, the threaded groove being formed on one side of the mounting plate, the threaded post being threadedly connected to the threaded groove, a lifting hole being formed at the top of the threaded post, a limiting groove being formed in the lifting hole, a fastening groove being formed at the bottom of the lifting hole, an annular toothed groove being formed at the bottom of the limiting groove, a lifting column being formed in the lifting hole, a toothed ring being formed between the lifting column and the limiting groove, an adjusting hole being formed at the bottom of the lifting column, an adjusting groove being formed on the adjusting hole, an adjusting plate being formed in the adjusting groove, an adjusting post being formed between the adjusting plate and the adjusting hole, the adjusting post being connected to the fastening groove by a compression spring, a wire hole being formed on the lifting post, an opening being formed on one side of the wire hole, and multiple wiring mechanisms being provided.

[0011] Furthermore, the present invention is improved in that the mounting mechanism includes mounting holes, which are formed on the mounting plate, and there are multiple mounting holes.

[0012] Furthermore, the present invention is improved by providing elastic blocks at both the top and bottom of the opening.

[0013] Furthermore, an improvement of this invention is that the compression spring is made of alloy.

[0014] Furthermore, the present invention is improved by providing a polytetrafluoroethylene coating on the inner wall of the wire hole.

[0015] Furthermore, the present invention is improved by providing arc edges at both ends of the wire hole.

[0016] (III) Beneficial Effects Compared with the prior art, this utility model provides a buried wiring device for power distribution switchgear, which has the following advantages: The wiring burial device in this power distribution switchgear features a threaded connection between a threaded post and a threaded groove on the mounting plate, allowing for rotatable adjustment of the overall height of the burial mechanism. The lifting post achieves angle fixation through the engagement of a toothed ring with the annular toothed groove at the bottom of the limiting groove. Pressing or pulling the lifting post compresses the spring, causing the toothed ring to disengage from the groove, thus flexibly adjusting the angle of the lifting post. This dual adjustment function adapts to the complex spatial layout within the switchgear, meeting the routing requirements of different cables and preventing excessive bending or stretching of the cables.

[0017] The cable guide hole on the lifting column has an opening, allowing the cable to be inserted directly into the hole from the side without having to pass it through the end. This significantly reduces the installation difficulty of long-distance, multi-turn cables and improves wiring efficiency.

[0018] By incorporating multiple cable-laying mechanisms, each mechanism can independently fix one or a group of cables, effectively preventing multiple cables from tangling and being squeezed together. This facilitates quick identification and operation of the target cable during later maintenance, improving maintenance convenience. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-4This utility model relates to a wiring device for a power distribution switchgear, comprising a mounting plate 1, on which a mounting mechanism and a wiring mechanism are provided. The wiring mechanism includes a threaded groove and a threaded post 2. The threaded groove is formed on one side of the mounting plate 1, and the threaded post 2 is threadedly connected to the threaded groove. A lifting hole is formed at the top of the threaded post 2, and a limiting groove 3 is formed in the lifting hole. A fastening groove is formed at the bottom of the lifting hole, and an annular toothed groove 4 is formed at the bottom of the limiting groove 3. A lifting column 5 is provided in the lifting hole, and a toothed ring 6 is provided between the lifting column 5 and the limiting groove 3. An adjusting hole is formed at the bottom of the lifting column 5, and an adjusting groove is formed on the adjusting hole. An adjusting plate 7 is provided in the adjusting groove, and an adjusting post 8 is provided between the adjusting plate 7 and the adjusting hole. The adjusting post 8 is connected to the fastening groove by pressure. A compression spring 9 is connected to the lifting column 5, which has a wire hole 12. An opening is provided on one side of the wire hole 12. The wire embedding mechanism has multiple components. In this embodiment, the threaded column 2 is threadedly connected to the threaded groove of the mounting plate 1. The overall height of the wire embedding mechanism can be adjusted by rotation. The lifting column 5 is nested in the lifting hole of the threaded column 2. The angle is fixed by the engagement of the toothed ring 6 with the annular toothed groove 4 at the bottom of the limiting groove 3. The compression spring 9 provides continuous engagement elastic force for the toothed ring 6. When the lifting column 5 is pulled, the compression spring 9 is stretched and deformed. The toothed ring 6 disengages from the toothed groove and rotates the angle of the lifting column 5. The compression spring 9, through its elastic force, can prevent the adjusting plate 7 and the adjusting column 8 from rotating with the lifting column 5, so that the compression spring 9 will not be twisted. After being released, the compression spring 9 resets and the toothed ring 6 re-engages with the annular toothed groove 4 to achieve fixation. The wire hole 12 is used for cable threading. The open design allows cables to be inserted from the side, eliminating the need for end insertion and simplifying the operation. Multiple burying mechanisms can independently fix different cables, preventing tangling. Furthermore, they can bend and fix cables at different angles, improving wiring efficiency and reducing cable bending damage. The entire process achieves layered and independent cable fixing, flexible adjustment of height and angle, and convenient installation, adapting to the complex wiring needs within switch cabinets.

[0023] To securely fix the mounting plate 1, the mounting mechanism in this design includes mounting holes 10, which are formed on the mounting plate 1. Multiple mounting holes 10 are provided, and the mounting plate 1 is fixed to the inner wall of the power distribution switchgear or a designated location via these holes and connecting components such as bolts and screws. The multiple mounting holes 10 provide flexible selection of fixing points, adapting to switchgear of different sizes and structures, ensuring the mounting plate 1 is securely fixed and preventing displacement due to vibration during use.

[0024] To prevent cables from accidentally slipping out of the opening, this design includes elastic blocks 11 at both the top and bottom of the opening. The deformation tension of these elastic blocks 11 clamps the opening, making it difficult for cables to slip out once inserted. This design retains the convenience of placing cables on the side while enhancing the reliability of the fixation by preventing accidental slippage through the elastic clamping mechanism.

[0025] To ensure the meshing stability of the toothed ring 6 and the annular toothed groove 4, in this design, the compression spring 9 is an alloy spring. The high elasticity, fatigue resistance, and corrosion resistance of the alloy material ensure that the spring maintains stable elastic force during long-term compression-reset cycles. This extends the service life of the wire embedding mechanism and ensures the meshing stability of the toothed ring 6 and the annular toothed groove 4.

[0026] To protect the cable insulation from scratches by the hole wall, the inner wall of the wire hole 12 in this design is coated with polytetrafluoroethylene (PTFE). This PTFE coating has an extremely low coefficient of friction and excellent wear and corrosion resistance, reducing friction between the cable and the hole wall during cable insertion or slight movement, protecting the cable insulation from scratches and reducing the risk of leakage. It also reduces frictional resistance, facilitating cable installation and subsequent fine-tuning. Both ends of the wire hole 12 are rounded, replacing sharp right angles to prevent rigid friction or scratching between the cable and the hole edge during insertion or exit. This further protects the cable insulation, preventing sharp edges from damaging the cable, and reduces the risk of operator injury during installation, improving safety.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
