Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a power distribution cabinet wiring component. Background Technology

[0002] A distribution cabinet is an important piece of equipment used for power distribution and control, typically composed of busbars, circuit breakers, disconnect switches, instrument transformers, instruments, and protective devices. Its working principle involves introducing electrical energy from the power source through the busbars, and then distributing, controlling, and protecting this energy through circuit breakers, disconnect switches, and other equipment. Instrument transformers are used to measure and monitor parameters such as current and voltage in the circuit, while instruments and protective devices display the operating status and cut off the power supply to ensure safety in the event of a fault. Inside the distribution cabinet, wiring is a core component, responsible for connecting the circuits between various parts to achieve power transmission and control. Proper wiring not only ensures the normal operation of the distribution cabinet but also reduces electromagnetic interference between lines, improving the reliability and safety of the equipment. Therefore, the wiring layout inside the distribution cabinet is an indispensable and crucial step in its design and installation.

[0003] In existing technologies, wiring in distribution cabinets typically employs a mounting plate combined with cable trays. Specifically, the wires need to pass through pre-drilled holes in the sidewalls of the cable tray, then be bundled and secured with cable ties before being placed inside the tray for installation and concealment. While this wiring method provides some organization and protection, it presents several problems. For instance, power lines, signal lines, and control lines within the distribution cabinet are often mixed together, lacking clear distinction and labeling. During later maintenance, wiring checks, or replacements, because the wires are bundled together, operators must untangle each bundle in the cable tray to locate the target line. This process is not only time-consuming and labor-intensive but also prone to damage or misoperation, significantly impacting maintenance efficiency and the operational safety of the distribution cabinet. Utility Model Content

[0004] The purpose of this utility model is to provide a wiring assembly for a power distribution cabinet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a power distribution cabinet wiring assembly, comprising: a wiring frame, the wiring frame being slidably connected to an adjustment frame on both sides, a wire fixing assembly being provided on the front side of the adjustment frame, and limit components being provided on both sides of the adjustment frame;

[0006] The cable fixing assembly includes a fixing frame, one end of which is fixedly connected to an adjusting frame, and the other end of which is rotatably connected to a cable fixing plate. The cable fixing plate is rotatably connected to one end of a connecting plate, and the other end of the connecting plate is rotatably connected to one end of a T-shaped frame. The other end of the T-shaped frame is slidably sleeved within the fixing frame and the adjusting frame. A limiting plate is fixedly sleeved on the end of the T-shaped frame near the connecting plate, and a return spring is fixedly connected between the limiting plate and the fixing frame.

[0007] Preferably, a handle is fixedly connected to the end of the T-shaped frame away from the limiting plate, and the end of the T-shaped frame closer to the limiting plate is rotatably connected to one end of the connecting plate via a small pin. The other end of the connecting plate is rotatably connected to the wire fixing plate via a small pin.

[0008] Preferably, the wire fixing plate and the fixing frame are rotatably connected by a large pin, and an insulating block is fixedly connected to the inner side wall of the wire fixing plate.

[0009] Preferably, the adjustment frame has sliding grooves at both ends, which are slidably connected to the slide rail. The slide rail is fixedly connected to both side walls of the wiring rack, and the side walls at both ends of the adjustment frame have insertion holes.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figure 1 - Figure 4 This utility model provides a technical solution: a wiring assembly for a power distribution cabinet, comprising: a wiring frame 1, which is fixedly installed on the inner wall of the power distribution cabinet to facilitate subsequent wiring operations; the wiring frame 1 is slidably connected to an adjusting frame 2 on both sides, allowing for easy adjustment of the position of the adjusting frame 2 to facilitate subsequent wiring at different locations; a wire fixing assembly is provided on the front side of the adjusting frame 2 to fix power lines, signal lines, and control lines; limit components are provided on both sides of the adjusting frame 2; and the wire fixing assembly... The component includes a fixed frame 3, one end of which is fixedly connected to an adjusting frame 2, and the other end of which is rotatably connected to a wire fixing plate 4. The wire fixing plate 4 is symmetrically arranged about the central plane of the fixed frame 3. The wire fixing plate 4 is rotatably connected to one end of a connecting plate 5, and the other end of the connecting plate 5 is rotatably connected to one end of a T-shaped frame 6. The other end of the T-shaped frame 6 is slidably sleeved in the fixed frame 3 and the adjusting frame 2. The fixed frame 3 and the adjusting frame 2 limit the movement of the T-shaped frame 6. A limiting plate 7 is fixedly sleeved on the end of the T-shaped frame 6 near the connecting plate 5. A return spring 8 is fixedly connected between the limiting plate 7 and the fixed frame 3.

[0024] Based on the required wiring and the installation location of electrical components, fix the wiring rack 1 to the side wall of the distribution box. Then, classify the lead wires of the electrical components according to the type of power line, signal line, and control line. When wiring, simply pull the T-shaped frame 6 away from the adjusting frame 2. The T-shaped frame 6 drives the limit plate 7 to move synchronously, causing the limit plate 7 to compress the return spring 8. At the same time, the T-shaped frame 6 is rotatably connected to the connecting plate 5, causing the connecting plate 5 to drive the wire fixing plate 4 to move. The wire fixing plate 4 is rotatably connected to the fixing frame 3, causing the two wire fixing plates 4 to move in opposite directions. At this time, place the classified wires on the two blocks respectively. Inside the cable fixing plate 4, the T-shaped bracket 6 is released, and then, under the reverse elastic force of the return spring 8, the T-shaped bracket 6 slides in the opposite direction between the fixed bracket 3 and the adjusting bracket 2. This causes the two cable fixing plates 4 to rotate towards each other under the limit of the fixed bracket 3 until the ends of the two cable fixing plates 4 away from the fixed bracket 3 abut together, thereby tightening the cable. Finally, according to the routing position, the adjusting bracket 2 is slid up and down on the wiring frame 1. When adjusted to the appropriate position, the adjusting bracket 2 is limited by the limiting component, thereby completing the wiring operation. In the later maintenance, cable tracing, or replacement and addition of lines, the corresponding wiring path can be quickly found according to the type.

[0025] Example 2: Based on Example 1, a handle 9 is fixedly connected to the end of the T-shaped frame 6 away from the limiting plate 7. The handle 9 facilitates the movement of the T-shaped frame 6. The end of the T-shaped frame 6 near the limiting plate 7 is rotatably connected to one end of the connecting plate 5 via a small pin 10. The other end of the connecting plate 5 is rotatably connected to the cable fixing plate 4 via a small pin 10. The connection via the small pin 10 facilitates the transmission between the T-shaped frame 6, the connecting plate 5, and the cable fixing plate 4. The cable fixing plate 4 is rotatably connected to the fixing frame 3 via a large pin 11. An insulating block 12 is fixedly connected to the inner wall of the cable fixing plate 4. The insulating block 12 fixedly installed on the inner wall of the cable fixing plate 4 further improves the safety during the wiring process.

[0026] Example 3: Based on Example 2, the adjusting frame 2 has sliding grooves 13 at both ends, which are slidably connected to the slide rail 14. The sliding grooves 13 and the slide rail 14 are slidably engaged, which facilitates the sliding adjustment of the adjusting frame 2. The slide rail 14 is fixedly connected to both side walls of the wiring frame 1. The side walls at both ends of the adjusting frame 2 have insertion holes 17. The surface of both side walls of the wiring frame 1 has positioning grooves 15, which are arranged in a vertical linear array. The rear side of the wiring frame 1 has mounting holes 16, which are arranged in a horizontal linear array. The mounting holes 16 facilitate the fixing of the wiring frame 1 to the distribution box. The limiting component includes a plug rod 18. One end of the plug rod 18 is slidably inserted into the positioning groove 15, and the other end of the plug rod 18 is fixedly connected to the lifting plate 19. A return spring 20 is fixedly connected between the lifting plate 19 and the side wall of the adjusting frame 2. The plug rod 18 is slidably sleeved in the insertion hole 17.

[0027] Based on the required wiring and the installation location of electrical components in the distribution box, the wiring rack 1 is fixed to the side wall of the distribution box through the mounting holes 16. Then, the lead wires of the electrical components are classified according to the type of power line, signal line and control line. Then, the various wire harnesses are limited and tightened by the wire fixing assembly. The corresponding number of adjustment racks 2 can be set on the wiring rack 1 as needed. By pulling the lifting plate 19 outward, the lifting plate 19 pulls the plug rod 18 and stretches the second return spring 20 at the same time. Thus, the adjustment rack 2 can be adjusted on the wiring rack 1 through the sliding engagement of the slide groove 13 and the slide rail 14. When it is adjusted to the desired position, the lifting plate 19 is released. Under the reverse elastic force of the second return spring 20, the plug rod 18 is limited and inserted into the positioning groove 15 opened in the side wall of the wiring rack 1 through the plug hole 17, thereby completing the adjustment of the adjustment rack 2, which improves the convenience and practicality of use.

[0028] 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.
