Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, specifically a high- and low-voltage switchgear that is easy to install and wire. Background Technology

[0002] High and low voltage switchgear are important power distribution and control equipment in power systems, widely used in industrial, commercial, and public utilities. They are primarily used to control and protect electrical equipment, ensuring the safety and stability of power supply. High and low voltage switchgear contains various electrical module units, such as circuit breakers, contactors, and relays, enabling current monitoring and control. However, due to the large number and complex arrangement of cables inside the switchgear, traditional wiring methods are often cumbersome and inflexible, leading to difficulties in subsequent maintenance and adjustments.

[0003] Patent CN210517402U discloses a high- and low-voltage switchgear that facilitates installation and wiring. The switchgear includes a cabinet, with a fixing block fixedly connected to the bottom of the cabinet's inner cavity. The top of the fixing block and the bottom of the cabinet both have matching limiting holes. Sliding rods are provided on both sides of the cabinet's inner cavity, with mounting blocks fixedly connected to the top and bottom of each sliding rod. A fixing shell is provided at the top and bottom between two sliding rods. The side of the mounting block away from the fixing shell is fixedly connected to the inner wall of the cabinet. This invention, by incorporating a fixing block, limiting holes, sliding rods, mounting blocks, fixing shells, sliding sleeves, handwheels, threaded rods, openings, clamping plates, clamping slots, pull rods, springs, and a pull rod, facilitates wiring within the switchgear and secures the cables, preventing damage from pulling. It solves the problem of inconvenient installation and wiring in existing high- and low-voltage switchgear. This high- and low-voltage switchgear, with its advantages of easy installation and wiring, is worthy of promotion.

[0004] While the existing technologies described above can secure cables and prevent them from being pulled and damaged, they still have some shortcomings in practical use. The fixing housing is fitted onto two sliding rods and fixed in position by threaded rods. Since both ends of the sliding rods are fixedly connected to mounting blocks, the number of fixing housings is limited to two, preventing users from flexibly increasing or decreasing the number of fixing housings according to actual wiring needs. Furthermore, cables must pass through the openings of the two fixing housings sequentially during installation or disassembly, causing inconvenience during installation or disassembly, requiring users to handle the entry and exit of each cable individually. In addition, since the clamps secure the cables by spring compression, both clamps need to be pulled outwards simultaneously during cable installation or disassembly, requiring at least two workers to complete the wiring operation for a single cable. These design limitations clearly affect the ease of wiring in high and low voltage switchgear and urgently need improvement. Therefore, we propose a high and low voltage switchgear that facilitates installation and wiring, aiming to further enhance its ease of installation and wiring functionality. Utility Model Content

[0005] The purpose of this utility model is to provide a high and low voltage switchgear that is easy to install and wire, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high- and low-voltage switchgear for easy installation and wiring includes a switchgear body, which provides installation space for electrical equipment and overall protection, combined with... Figure 1 and Figure 3 As shown, the bottom of the high and low voltage switchgear body is provided with multiple wire holes for cables to pass through. The wire holes are used for cables to enter the cabinet and guide the wiring direction. Support blocks are provided on the left and right sides of the inner wall of the high and low voltage switchgear body and near the bottom of the rear side. The support blocks are used to fix rectangular uprights. Rectangular uprights are provided on the top of the two support blocks. The rectangular uprights are used to install adjustable wiring components. A wiring component is detachably connected between the two rectangular uprights. The wiring component is used to modularly fix the cables and supports flexible addition or reduction of the quantity.

[0008] like Figure 6 As shown, the wiring assembly includes a U-shaped horizontal plate with its opening facing forward. The U-shaped horizontal plate provides an installation platform for the wire fixing components. Both sides of the U-shaped horizontal plate are movably connected to connectors for detachable connection with rectangular uprights. The connectors are used to adjust the height of the wiring assembly and enable quick assembly and disassembly. The rear side of the U-shaped horizontal plate is provided with multiple wire fixing components arranged at equal intervals on the left and right sides. The wire fixing components are used to clamp a single cable and support quick assembly and disassembly.

[0009] The cable fixing component includes a U-shaped frame with its opening facing right. The U-shaped frame is used to accommodate cables and provide installation space for the clamping structure. A fixed clamping plate is provided on the front side of the inner wall of the U-shaped frame. The fixed clamping plate is used to cooperate with the movable clamping plate to clamp the cable. A threaded rod is threadedly connected to the rear side of the U-shaped frame. The threaded rod is used to drive the movable plate to move back and forth to adjust the clamping force. The front end of the threaded rod is rotatably connected to a movable plate. The movable plate is used to drive the movable clamping plate to move horizontally. A movable clamping plate is provided on the front side of the movable plate, which is arranged in a front-back opposite manner to the fixed clamping plate. The movable clamping plate is used to clamp or release the cable by moving back and forth. When the movable clamping plate moves forward, the cable is clamped and fixed by the fixed clamping plate and the movable clamping plate. When the movable clamping plate moves backward, the cable is released and can move to the right to be removed from the U-shaped frame, which facilitates the cable wiring work to be completed by a single worker.

[0010] Preferred, such as Figure 2As shown, an operation port is provided on the rear side of the high and low voltage switchgear body, which facilitates wiring operations for staff. A maintenance plate for sealing the operation port is bolted to the rear side of the high and low voltage switchgear body. The maintenance plate is used to protect the operation port and support disassembly and maintenance.

[0011] Preferred, such as Figure 3 As shown, the supporting block and the rectangular upright are integrally formed, which enhances the stability of the support. One side of the supporting block is bolted to the side of the inner wall of the high and low voltage switchgear body, and the top of the rectangular upright is bolted to the top of the inner wall of the high and low voltage switchgear body.

[0012] Preferred, combined Figure 4 and Figure 5 As shown, the connector includes a rectangular movable rod, which is used to adjust the position of the U-shaped horizontal plate laterally. The U-shaped horizontal plate has rectangular holes on both the left and right sides for the rectangular movable rod to pass through. The rectangular holes allow the rectangular movable rod to slide to adapt to the installation requirements. The rectangular movable rod has a U-shaped clamping block at one end near the rectangular upright, which is used to clamp the rectangular upright and fix its position.

[0013] The rear side of the U-shaped clamping block is threaded with a clamping bolt. The threaded end of the clamping bolt abuts against the rear side of the rectangular upright. The clamping bolt is used to lock the connection between the U-shaped clamping block and the rectangular upright.

[0014] The rectangular movable rod is provided with an anti-detachment block at the end away from the rectangular upright. The anti-detachment block is used to prevent the rectangular movable rod from coming out of the rectangular hole. When the U-shaped clamping block is connected and fixed to the rectangular upright, the side of the anti-detachment block is in contact with the side of the inner wall of the U-shaped horizontal plate. When the two connecting pieces are connected and fixed to the two rectangular uprights respectively, the position of the U-shaped horizontal plate is also fixed, and no left or right displacement will be found.

[0015] Preferred, such as Figure 6 As shown, both the fixed clamping plate and the movable clamping plate have a "V" shaped structure. The "V" shaped structure increases the contact points with the cable to improve the fixing stability. The concave surfaces of both the fixed clamping plate and the movable clamping plate are bonded with rubber liners of the same shape. The rubber liners are used to protect the cable surface and enhance the clamping friction.

[0016] A limiting rod is provided on the rear side and near the left side of the movable plate. The rear end of the limiting rod passes through the rear side of the inner wall of the U-shaped frame to the outside. The limiting rod is used to restrict the rotation of the movable plate and ensure the stability of linear movement.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This high and low voltage switchgear, which is easy to install and wire, allows users to freely increase or decrease the number of wiring components according to actual needs through the combination of detachable wiring components and rectangular uprights, breaking through the problem of limited number of fixed shells in traditional designs and significantly improving wiring flexibility.

[0019] 2. This high and low voltage switchgear is easy to install and wire. The wire fixing parts adopt a U-shaped frame structure with the opening facing the right. The cable can be directly put in or taken out from the right side without having to pass through multiple layers of fixing shell openings. A single person can quickly complete the installation or removal of the cable, which greatly improves the work efficiency.

[0020] 3. This high and low voltage switchgear, which is easy to install and wire, uses a threaded rod to drive the movable clamping plate to move back and forth. The cable clamping or release can be completed by simply rotating the threaded rod. There is no need to operate multiple clamping plates at the same time or rely on spring mechanisms, which completely solves the problem of requiring two people to work together in traditional designs.

[0021] 4. This high and low voltage switchgear, which is easy to install and wire, adopts a V-shaped structure design for both the fixed clamping plate and the movable clamping plate, with rubber lining. This increases the contact points with the cables and avoids damage to the cable surface during clamping. At the same time, the limiting longitudinal rod ensures the linear stability of the clamping action and prevents the cables from loosening. Attached Figure Description

When the movable clamping plate 435 moves forward, the cable is clamped and fixed by the fixed clamping plate 432 and the movable clamping plate 435. When the movable clamping plate 435 moves backward, the cable is released and can move to the right to move out of the U-shaped frame 431, which makes it convenient for a single worker to complete the cable wiring operation.

[0035] In this embodiment, as Figure 2 As shown, an operation port 120 is provided on the rear side of the high and low voltage switchgear body 100. The operation port 120 facilitates wiring operations for staff. A maintenance plate 500 for sealing the operation port 120 is bolted to the rear side of the high and low voltage switchgear body 100. The maintenance plate 500 is used to protect the operation port 120 and support disassembly and maintenance.

[0036] Specifically, such as Figure 3As shown, the support block 200 and the rectangular upright 300 are integrally formed structures, which enhances the stability of the support. One side of the support block 200 is bolted to the side of the inner wall of the high and low voltage switchgear body 100, and the top of the rectangular upright 300 is bolted to the top of the inner wall of the high and low voltage switchgear body 100.

[0037] Furthermore, in combination Figure 4 and Figure 5 As shown, the connector 420 includes a rectangular movable rod 421, which is used to adjust the position of the U-shaped horizontal plate 410 laterally. The U-shaped horizontal plate 410 has rectangular holes 411 on both the left and right sides for the rectangular movable rod 421 to pass through. The rectangular holes 411 allow the rectangular movable rod 421 to slide to adapt to the installation requirements. A U-shaped clamping block 422 is provided at one end of the rectangular movable rod 421 near the rectangular upright 300. The U-shaped clamping block 422 is used to clamp the rectangular upright 300 and fix its position.

[0038] The rear side of the U-shaped clamping block 422 is threaded with a clamping bolt 423. The threaded end of the clamping bolt 423 abuts against the rear side of the rectangular upright 300. The clamping bolt 423 is used to lock the connection between the U-shaped clamping block 422 and the rectangular upright 300.

[0039] The rectangular movable rod 421 is provided with an anti-detachment block 424 at the end away from the rectangular upright rod 300. The anti-detachment block 424 is used to prevent the rectangular movable rod 421 from coming out of the rectangular hole 411. When the U-shaped clamping block 422 is connected and fixed to the rectangular upright rod 300, the side of the anti-detachment block 424 is in contact with the side of the inner wall of the U-shaped horizontal plate 410. When the two connecting pieces 420 are connected and fixed to the two rectangular upright rods 300 respectively, the position of the U-shaped horizontal plate 410 is also fixed, and no left or right displacement will be found.

[0040] Furthermore, such as Figure 6 As shown, both the fixed clamping plate 432 and the movable clamping plate 435 have a "V" shaped structure. The "V" shaped structure increases the contact points with the cable to improve the fixing stability. The concave surfaces of both the fixed clamping plate 432 and the movable clamping plate 435 are bonded with rubber liners 436 of the same shape. The rubber liners 436 are used to protect the cable surface and enhance the clamping friction.

[0041] A limiting rod 437 is provided on the rear side and near the left side of the movable plate 434. The rear end of the limiting rod 437 passes through the rear side of the inner wall of the U-shaped frame 431 to the outside. The limiting rod 437 is used to limit the rotation of the movable plate 434 and ensure the stability of linear movement.

After the cable passes through the wire hole 110 into the cabinet, it is directly placed into the U-shaped bracket 431 of the wire fixing component 430, and the threaded rod 433 is rotated. The movable plate 434 is pushed forward, causing the movable clamping plate 435 and the fixed clamping plate 432 to clamp the cable. The V-shaped structure and rubber liner 436 ensure clamping stability and do not damage the cable surface. The limiting rod 437 restricts the rotation of the movable plate 434 to ensure linear movement. After the wiring is completed, the internal connection is checked through the operation port 120. The maintenance plate 500 closes the operation port 120 with bolts. When adjustment or maintenance is required, the maintenance plate 500 is removed and the clamping bolts 423 are loosened to adjust the height of the wiring assembly 400 or increase or decrease the number of wire fixing pieces 430.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
