Description

Technical Field

[0001] This utility model relates to the field of cable routing mechanism technology, and in particular to a cable routing mechanism for low-voltage switchgear. Background Technology

[0002] Low-voltage switchgear is a key piece of equipment in power systems used for power distribution and control. It is commonly used in industrial and mining enterprises, buildings, and other similar settings. It centrally distributes low-voltage power from the upstream power source to various outgoing circuits via busbars, providing stable power to loads such as motors, lighting, and air conditioning. The cabinet integrates components such as circuit breakers, contactors, and current transformers, and features overload protection, short-circuit isolation, remote control, and power metering functions. Its modular design ensures a compact layout and high protection level, effectively preventing electric shock and dust intrusion. Furthermore, standardized wiring and clear labeling facilitate maintenance and repair, ensuring the safe and efficient operation of the power system.

[0003] In the process of wiring devices in low-voltage distribution cabinets, the wiring is a key layout design of the distribution cabinet. It is necessary to ensure that the wiring route is clear and clearly marked, so as to facilitate daily maintenance and inspection and avoid the risk of short circuits caused by messy wiring. However, the conventional way of wiring is to use cable ties to bind and restrain the wires after the wiring is completed. Although this method can restrain the wires simply, due to the lack of prior planning, the wiring harnesses are often randomly routed and subsequent maintenance and disassembly are cumbersome. It is difficult to meet the dual requirements of safety and maintainability of modern power distribution systems. Based on this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Example 1: Refer to Figures 1-7A low-voltage switchgear cable management mechanism includes a housing 1, a circuit breaker 11 installed inside the housing 1, and a wire 4 connected to the circuit breaker 11. It also includes a base plate 2 installed inside the housing 1, a cover plate 3 installed on the base plate 2, and multiple compression springs 34 inside the cover plate 3. When the cover plate 3 is closed on the base plate 2, the compression springs 34 clamp the wire 4. Cable routing grooves 25 and bending grooves 23 are provided on the back of the cover plate 3 and the base plate 2, respectively. The wire 4 is connected to the circuit breaker 11 via the limiting of the cable routing grooves 25 and bending grooves 23. A snap-fit ​​groove 22 is provided on the back of both the base plate 2 and the cover plate 3, and a snap-fit ​​block 31 is provided on the cover plate 3, the snap-fit ​​block 31 corresponding to the snap-fit ​​groove 22. A positioning groove 24 is provided on the back of both the base plate 2 and the cover plate 3, and multiple compression springs 34 are provided on the cover plate 3. The spring 34 and the compression spring 34 are positioned corresponding to the positioning groove 24. The base plate 2 is provided with a positioning hole 21 and a limiting frame 27. The cover plate 3 is provided with a support block 33, which is positioned corresponding to the limiting frame 27. A positioning rod 322 is slidably connected to the support block 33. A connecting rod 32 is connected between two positioning rods 322 located at the top or bottom. A tension spring 321 is connected between the positioning rod 322 and the snap-fit ​​block 31. When the positioning rod 322 is inserted into the positioning hole 21, the cover plate 3 and the base plate 2 are fastened together. The cover plate 3 is provided with a positioning hole 21. Multiple cover plates 3 are spliced ​​together in sequence through the insertion of positioning rods 322 and positioning holes 21 to clamp and fix the wire 4. The base plate 2 is provided with an installation block 26 for mounting on the box 1.

[0030] In this utility model, such as Figure 3 and Figure 4 As shown, by setting a base plate 2 and opening a wiring groove 25 and a bending groove 23 on the base plate 2, the wiring of the wire 4 can be constrained and laid out without pre-bending the wire 4. The wire 4 can be connected to the circuit breaker 11 simply by placing and bending it according to the layout of the wiring groove 25 and the bending groove 23. This eliminates the need for the user to support the wire 4 during installation and wiring, thereby reducing the number of steps required for wiring.

[0031] By setting the snap-fit ​​groove 22 and snap-fit ​​block 31, the cover plate 3 and the base plate 2 will not be misaligned when they are fastened together. By setting the positioning groove 24 and the compression spring 34, the compression spring 34 can squeeze and clamp the wire 4 when the cover plate 3 and the base plate 2 are fastened together. At the same time, by utilizing the arc-shaped elastic setting of the compression spring 34, wires 4 of different sizes can be clamped and fixed. By fastening together, multiple wires 4 can be positioned and clamped at multiple points at equal intervals at one time, thereby improving the installation progress while ensuring clamping accuracy.

[0032] Both the base plate 2 and the cover plate 3 are provided with positioning holes 21. When the cover plate 3 is fastened to the base plate 2, the positioning rod 322 is inserted into the positioning hole 21, thereby completing the locking and limiting, thus achieving the effect of quick installation and disassembly, and improving the wiring efficiency of the installer. The positioning rods 322 located at the top and bottom are connected together by the connecting rod 32, so that the user can easily pull the connecting rod 32 to drive the positioning rod 322 to disengage from the positioning groove 24 and complete the quick disassembly.

[0033] Multiple cover plates 3 can be spliced ​​together in sequence, so that multiple sets can be stacked according to the number of wires 4. Through modularization, they can be spliced ​​according to different needs. The back plate of the outermost cover plate 3 does not have many wire grooves, so that the overall appearance of the device after splicing is relatively neat.

[0034] The base plate 2 is provided with mounting blocks 26, and the mounting bolts are installed into the housing 1 through the mounting blocks 26.

[0035] During installation, the user first installs the mounting block 26 and the circuit breaker 11 onto the enclosure 1. Then, the wire 4 is placed in the wiring trough 25 and the bending trough 23 according to the required wiring position, and the wire 4 is connected to the circuit breaker 11. After the connection is completed, the cover plate 3 is fastened onto the base plate 2, and the positioning rod 322 is inserted into the positioning hole 21 to complete the fixed limit. The above wiring operation is repeated according to the number of wires, and the cover plate 3 is fastened in sequence. When it is necessary to disassemble, simply pull the connecting rod 32 at the top and bottom positions to move it to both sides so that the positioning rod 322 is disengaged from the positioning hole 21 to complete the disassembly of the cover plate 3.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
