Description

Technical Field

[0001] This utility model relates to the field of auxiliary accessories for electrical cabinets, specifically to a wiring structure for electrical cabinets. Background Technology

[0002] Electrical cabinets are core equipment used to install electrical components and realize circuit control and power distribution functions. They typically require a large number of wires to be laid inside to achieve signal transmission and power supply between various electrical components. During the assembly and use of electrical cabinets, the orderly wiring directly affects the operational stability, maintenance convenience, and space utilization of the cabinet. The current wiring methods for electrical cabinets mostly use fixed cable trays or cable ties. Fixed cable trays have fixed wiring space and cannot be flexibly expanded. When it is necessary to add branch wires or adjust the wiring layout, the original cable trays need to be disassembled and reinstalled, which is cumbersome and can easily disrupt the original wiring order. While cable ties offer greater flexibility, the wires are prone to tangling and becoming messy. This not only affects the aesthetics of the electrical cabinet but also causes great inconvenience for later maintenance. In addition, messy wires may also pose a safety hazard due to poor heat dissipation.

[0003] Therefore, it is necessary to invent a wiring structure for electrical cabinets to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a wiring structure for electrical cabinets. By setting multiple modular mounting slots on both sides of the base and cooperating with wiring expansion components, the problem of fixed wiring space in existing technologies, which cannot be flexibly expanded, can be solved.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wiring structure for an electrical cabinet, comprising a base and a protective cover covering the front of the base.

At least one wiring expansion component is provided on each side of the base. The wiring expansion component can be selectively inserted into any mounting slot. Each wiring expansion component includes an expansion box, which is inserted into the mounting slots on both sides of the base. Two sets of elastic supports extending in the vertical direction are fixedly connected to the inner walls of the left and right sides of the expansion box. The elastic element is located entirely inside the expansion box. A protrusion is fixedly connected to the free end of each set of elastic elements on the opposite side and away from the inner wall of the expansion box. A groove with a shape and position that matches the protrusion is formed on the inner wall of the mounting slot of the base. The protrusion is inserted into the groove. Two sets of sliding rods that move vertically are slidably connected to the inner wall of the base. Both sets of sliding rods are located inside the two sets of elastic elements and are symmetrically arranged. A sloped drive block is fixedly connected to the opposite side of each set of sliding rods. The extension ends of the two sets of sliding rods extending outside the expansion box are fixedly connected to the same operating part.

[0006] Preferably, the base is fixedly connected to two integrally formed mounting wings, and the surface of the mounting wings is provided with mounting holes for fixing the base into the electrical cabinet.

[0007] Preferably, the protective cover has heat dissipation holes extending through the front and rear surfaces of the protective cover, and the base and the protective cover are detachably connected by snap fasteners.

Detailed Implementation

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model provides, for example Figure 1 - Figure 3 The wiring structure for an electrical cabinet shown includes a base 11 and a protective cover 12 covering the front of the base 11 for protecting cables. A wiring groove 13 is provided on the front of the base 11, which limits the main wire and prevents it from shifting arbitrarily, thus achieving the initial orderly arrangement of the main wire. An integrally formed mounting wing 14 is fixedly connected to both sides of the base 11. The surface of the mounting wing 14 has mounting holes 15 for fixing the base 11 into the electrical cabinet. The surface of the protective cover 12 has heat dissipation holes 16 that penetrate the front and rear surfaces of the protective cover 12, allowing air circulation inside and outside, which helps dissipate heat inside the cabinet and improves electrical safety performance. The base 11 and the protective cover 12 are detachably connected by a buckle 17. Multiple evenly distributed mounting slots 111 are provided on both sides of the base 11. At least one wiring extension component 20 is provided on both sides of the base 11, and the wiring extension component 20 can be selectively inserted into any mounting slot 111.

[0017] like Figure 3 - Figure 5As shown, the cabling expansion assembly 20 includes an expansion box 21, which is inserted into the mounting slots 111 on both sides of the base 11. Two sets of elastic members 22 extending in the vertical direction are fixedly connected to the inner walls of the left and right sides of the expansion box 21. The elastic members 22 are elongated strips made of spring steel and can undergo elastic deformation under external force. The elastic members 22 are completely located inside the expansion box 21. A protrusion 23 is fixedly connected to the free end of the two sets of elastic members 22 on the opposite side and away from the inner wall of the expansion box 21. The cross-sectional shape of the protrusion 23 is semi-circular or arc-shaped. A groove 24 with a shape and position that matches the protrusion 23 is opened on the inner wall of the mounting slots 111 of the base 11. The protrusion 23 is inserted into the groove 24. A sliding connection is provided on the inner wall of the base 11, allowing for vertical displacement. Two sets of sliding rods 25 are located inside the two sets of elastic members 22 and are symmetrically arranged. An inclined driving block 26 is fixedly connected to the opposite side of the two sets of sliding rods 25. The cross-sectional shape of the inclined driving block 26 is set as an isosceles trapezoid or triangle. The extension ends of the two sets of sliding rods 25 extending to the outside of the expansion box 21 are fixedly connected to the same operating part 27. When the expansion box 21 is inserted to the preset depth, the protrusion 23 at the free end of the elastic member 22 moves to the groove 24 on the inner wall of the mounting slot 111. The elastic member 22 loses its compression and restores its deformation, driving the protrusion 23 to be inserted into the groove 24. Through the interlocking action of the protrusion 23 and the groove 24, the expansion box 21 is quickly fixed to the base 11, preventing the expansion box 21 from falling out of the mounting slot 111.

[0018] like Figure 3 - Figure 5 As shown, the cabling expansion assembly 20 also includes a guide block 28, which is fixedly connected to the back of the expansion box 21. The inner wall of the mounting slot 111 of the base 11 is provided with a guide groove 29. The guide block 28 is inserted into the inner wall of the guide groove 29. The cooperation between the guide block 28 and the guide groove 29 plays a precise guiding role, preventing the expansion box 21 from shifting when it is inserted, and ensuring that the expansion box 21 and the mounting slot 111 are precisely connected. The front of the expansion box 21 is provided with an expansion cabling groove 211 for laying cables. The expansion cabling groove 211 on the front of the expansion box 21 is connected to the main cabling groove 13 to form a continuous cable channel. One end of the branch wire can be extended from the expansion cabling groove 211 into the cabling groove 13 and connected to the corresponding main wire, realizing the orderly connection of the branch wire and the main wire. At the same time, the partition design of the expansion cabling groove 211 and the cabling groove 13 avoids the main wire and the branch wire from getting tangled and messy.

[0019] The working principle of this utility model is as follows: First, the base 11 is fixed to the mounting beam inside the electrical cabinet using screws or bolts through the mounting holes 15 on the mounting wing 14, thus completing the positioning and fixing of the base 11. When it is necessary to expand the wiring channel to meet the wiring needs of more cables or specific routing, the wiring expansion component 20 can be installed in the appropriate mounting slot 111. The expansion box 21 is aligned with the selected mounting slot 111 and pushed in the insertion direction. During the insertion process, the guide block 28 on the back of the expansion box 21 slides into the guide groove 29 on the base 11, so that the expansion box 21 is smoothly and accurately centered and inserted.

[0020] As the expansion box 21 continues to be inserted, the protrusion 23 at the free end of the internal elastic element 22 contacts the inner wall of the mounting slot 111. Because the protrusion 23 has a semi-circular or arc-shaped cross-section, its surface forms a smooth guiding slope, causing the elastic element 22 to undergo elastic compression deformation inwards. When the expansion box 21 is fully inserted, the protrusion 23 is precisely aligned with the groove 24 on the base 11. Under the restoring action of the elastic element 22's own elastic force, the protrusion 23 automatically springs in and locks into the groove 24. Then, the operator manually pushes the operating part 27 located outside the expansion box 21, causing the two sets of sliding rods 25 to move synchronously. The inclined driving block 26 at the end of the sliding rod 25 moves accordingly. Since the cross section of the inclined driving block 26 is an isosceles trapezoid or triangle, its inclined surface contacts the inner wall of the elastic member 22 and generates an outward thrust, forcing the two sets of elastic members 22 to overcome the elastic force and expand outward, so that the protrusion 23 is stably inserted into the groove 24, preventing the deformation of the elastic member 22 and the detachment of the protrusion 23, thereby realizing the quick locking and reliable fixation of the wiring expansion assembly 20. At this time, the expansion wiring groove 211 on the front of the expansion box 21 is connected to the main wiring groove 13 on the base 11 to form a continuous cable channel, which can be used to lay branch cables.

[0021] When it is necessary to disassemble or replace the wiring expansion assembly 20, the operating part 27 located outside the expansion box 21 is manually pushed to drive the two sets of sliding rods 25 to move synchronously. The inclined driving block 26 at the end of the sliding rod 25 is displaced accordingly, releasing the restriction on the elastic element 22. At this time, the expansion box 21 can be pulled out to remove it from the mounting slot 111, realizing quick disassembly and expansion. When it is necessary to adjust the branch wire layout or repair the wires, the number and position of the wiring expansion assembly 20 can be flexibly changed according to the electrical layout, improving flexibility and adaptability.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
