Technical Field
[0001] This application relates to the field of low-voltage switchgear technology, specifically to a low-voltage switchgear that is easy to wire. Background Technology
[0002] Low-voltage switchgear, also known as low-voltage switch cabinet, is a complete set of electrical equipment used for converting and distributing electrical energy. Its rated operating voltage does not exceed 1000V, and it is widely used in power plants, substations, and power departments of industrial and mining enterprises for receiving and distributing electrical energy. Low-voltage switchgear is characterized by its small size, light weight, compact structure, and ease of installation and use. It can provide the required power to various electrical devices, including power distribution and lighting distribution.
[0003] Instruments are installed on the back of the cabinet door of the low-voltage switchgear. The instruments need to be wired to connect to the internal components of the low-voltage switchgear. The existing wiring method is to wrap a large number of wires together with tape to organize the wires. However, wrapping the wires with tape is not only laborious, but also inconvenient for subsequent maintenance and replacement, increasing the workload of workers. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides an easy-to-wire low-voltage switchgear, which facilitates the wiring and organization of a large number of wires, avoids the use of tape for wiring, and facilitates subsequent maintenance and replacement of wires. It also reduces the workload of workers and improves work efficiency. This solves the problem that the current wiring method for instruments and internal components of low-voltage switchgear generally involves wrapping a large number of wires together with tape for wiring, which is not only laborious but also inconvenient for subsequent maintenance and replacement, increasing the workload of workers.
[0005] To achieve the above objectives, this application provides the following technical solution: a low-voltage cabinet that is easy to wire, comprising a low-voltage cabinet body, a cabinet door hinged to the front of the low-voltage cabinet body, a cable tray fixedly connected to the inner wall of the cabinet door, cable trays having equidistantly arranged cable tray grooves inside the cable tray, a pressure plate hinged to the top of the cable tray, a positioning rod inserted into the inner sliding rod of the cable tray, a positioning hole inside the pressure plate, the outer circumferential surface of the positioning rod being slidably inserted into the pressure plate through the positioning hole, a base plate fixedly connected to the inner wall of the cabinet door, and a cable tray slidably connected to the outer surface of the base plate.
[0006] The above solution addresses the common practice of using tape to bundle numerous wires together for wiring between existing instruments and low-voltage cabinet components. However, this method is labor-intensive and makes subsequent maintenance and replacement inconvenient, increasing the workload for workers. By installing a cable management unit with equally spaced cable trays inside, the wires can be neatly arranged, avoiding the need for tape and reducing the workload for workers. This improves work efficiency and facilitates subsequent maintenance and replacement. Furthermore, the horizontally movable cable management tubes further enhance the neatness of the wires inside the low-voltage cabinet.
[0007] Furthermore, the bottom surface of the pressure plate is fixedly connected with equidistantly arranged limiting protrusions, the positions of the limiting protrusions and the wire harness grooves are respectively corresponding, and the limiting protrusions are respectively inserted into the interior of the wire harness grooves.
[0008] The above solution uses limiting protrusions to further restrict the wires inside the cable tray, pressing them tightly to improve their stability and prevent them from easily moving out of the cable tray.
[0009] Furthermore, a collar is fixedly sleeved on the outer circumferential surface of the positioning rod, and a spring is fixedly connected to the side of the collar near the cable harness seat. The other end of the spring is fixedly connected to the outer surface of the cable harness seat.
[0010] Through the above scheme, the spring can exert a reaction force on the positioning rod with its own elasticity, so that the positioning rod is always inserted into the positioning hole to position and limit the pressure plate. At the same time, it can also cause the positioning rod to move back automatically, and automatically complete the positioning operation of the pressure plate.
[0011] Furthermore, the end face of the positioning rod near the positioning hole is an inclined surface.
[0012] The above scheme enables the positioning rod to be squeezed by the inclined surface of the positioning rod during the downward rotation of the pressure plate, causing the positioning rod to move laterally outward. Finally, it automatically moves back under the action of the spring, thus automatically completing the positioning of the pressure plate.
[0013] Furthermore, two limiting rods are fixedly connected to the outer circumferential surface of the collar, and the outer circumferential surface of the limiting rods is slidably inserted into the inside of the cable tie seat.
[0014] The above method restricts the positioning rod, preventing it from rotating and ensuring that it always moves laterally, thus improving the stability of the positioning rod's movement.
[0015] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of each of the limiting rods.
[0016] The above method restricts the positioning rod, preventing it from easily detaching from the cable tie holder.
[0017] Furthermore, a slider is fixedly connected to the outer surface of the wire bundle tube, and a groove is provided inside the base plate. The outer surface of the slider is slidably connected to the base plate through the groove. The slider has a T-shaped structure, and the groove has a T-shaped structure adapted to the slider.
[0018] The above scheme enables the cable bundle to move along the slide groove as a track, allowing for easy adjustment of the cable bundle's position according to specific needs. This improves the cable bundle's flexibility and practicality. The T-shaped slider and slide groove ensure that the cable bundle always moves laterally, preventing it from easily falling off and improving its stability.
[0019] Furthermore, the internal threaded connection of the cable bundle has two positioning bolts, and the bottom surface of each positioning bolt is in contact with the outer surface of the base plate.
[0020] The above method allows for tightening the positioning bolts to restrict the positioning of the cable bundle, preventing it from moving easily and facilitating the adjustment of its position.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This easy-to-connect low-voltage switchgear, by incorporating a cable management unit and equidistantly spaced cable trays within the unit, ensures neat cable arrangement, eliminating the need for wrapping or binding cables with tape. This reduces worker workload, improves efficiency, and facilitates subsequent cable maintenance and replacement. The horizontally movable cable tray further enhances cable organization, improving the overall neatness of the cables inside the switchgear. This solves the problem of using tape to wrap and organize cables, which is not only laborious but also inconvenient for subsequent maintenance and replacement, increasing worker workload.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0025] Please see Figure 1 , Figure 3 and Figure 4 This embodiment of a low-voltage switchgear for easy wiring includes a low-voltage switchgear body 1. A cabinet door 2 is hinged to the front of the low-voltage switchgear body 1. A cable tie seat 3 is fixedly connected to the inner wall of the cabinet door 2. The cable tie seat 3 has cable tie grooves 4 arranged at equal intervals inside. A pressure plate 5 is hinged to the top of the cable tie seat 3. A positioning rod 7 is inserted into the sliding rod inside the cable tie seat 3. A positioning hole 8 is opened inside the pressure plate 5. The outer circumferential surface of the positioning rod 7 is slidably inserted into the pressure plate 5 through the positioning hole 8. A base plate 12 is fixedly connected to the inner wall of the cabinet door 2. A cable tie tube 13 is slidably connected to the outer surface of the base plate 12.
[0026] Please see Figure 2 and Figure 3 The bottom surface of the pressure plate 5 is fixedly connected with equidistantly arranged limiting protrusions 6. The limiting protrusions 6 correspond to the positions of the wire harness groove 4. The limiting protrusions 6 extend into the interior of the wire harness groove 4. The limiting protrusions 6 further restrict the wires inside the wire harness groove 4, press the wires inside the wire harness groove 4 tightly, improve the stability of the wires, and prevent the wires from easily moving and falling off from the wire harness groove 4.
[0027] Please see Figure 2 and Figure 3 A collar 17 is fixedly sleeved on the outer circumference of the positioning rod 7. A spring 9 is fixedly connected to the side of the collar 17 near the wire harness seat 3. The other end of the spring 9 is fixedly connected to the outer surface of the wire harness seat 3. The spring 9 can apply a reaction force to the positioning rod 7 with its own elasticity, so that the positioning rod 7 is always inserted into the positioning hole 8 to position and limit the pressure plate 5. At the same time, it can also cause the positioning rod 7 to move back automatically and automatically complete the positioning operation of the pressure plate 5.
[0028] Please see Figure 2 and Figure 3The end face of the positioning rod 7 near the positioning hole 8 is inclined, which causes the pressure plate 5 to rotate and move downward. Under the action of the inclined surface of the positioning rod 7, the positioning rod 7 is squeezed, causing the positioning rod 7 to move laterally outward. Finally, under the action of the spring 9, it automatically moves back, automatically completing the positioning of the pressure plate 5.
[0029] Please see Figure 2 and Figure 3 Two limiting rods 10 are fixedly connected to the outer circumferential surface of the collar 17. The outer circumferential surface of the limiting rods 10 is slidably inserted into the inside of the cable harness 3 to restrict the positioning rod 7, prevent the positioning rod 7 from rotating, and ensure that the positioning rod 7 always moves laterally, thereby improving the stability of the positioning rod 7's movement.
[0030] Please see Figure 2 and Figure 3 Each limiting rod 10 has a limiting ring 11 fixedly sleeved on its outer circumference to restrict the positioning rod 7 and prevent the positioning rod 7 from easily falling out of the cable tie 3.
[0031] Please see Figure 1 and Figure 4 A slider 14 is fixedly connected to the outer surface of the cable tie 13. A groove 15 is provided inside the base plate 12. The outer surface of the slider 14 is slidably connected to the base plate 12 through the groove 15. The slider 14 has a T-shaped structure, and the groove 15 has a T-shaped structure that is adapted to the slider 14. This allows the cable tie 13 to move along the slider 14 with the groove 15 as the track. This facilitates the adjustment of the position of the cable tie 13 according to specific needs, improving the flexibility and practicality of the cable tie 13. The T-shaped slider 14 and the groove 15 enable the cable tie 13 to always move laterally, preventing the cable tie 13 from easily falling off and improving the stability of the cable tie 13.
[0032] Please see Figure 1 and Figure 4 The cable bundle 13 has two internal threaded connections with positioning bolts 16. The bottom surface of each positioning bolt 16 contacts the outer surface of the base plate 12. The positioning bolts 16 can be tightened to position and restrict the cable bundle 13, preventing it from moving easily and facilitating the adjustment of its position.
[0033] This embodiment of an easy-to-connect low-voltage switchgear, by setting a cable tray 3 and opening equidistantly arranged cable tray grooves 4 inside the cable tray 3, enables the wires to be neatly arranged, avoiding the use of tape to wrap and bind the wires, reducing the workload of workers, improving work efficiency, and also facilitating subsequent maintenance and replacement of the wires. By setting a cable tray 13 that can move laterally, it is easy to further arrange the wires, improve the neatness of the wires inside the low-voltage switchgear, and solve the problem that using tape to wrap and arrange the wires inside the low-voltage switchgear is not only laborious, but also inconvenient for subsequent maintenance and replacement, increasing the workload of workers.
[0034] It should be noted that the limiting protrusion 6 is made of rubber.
[0035] The working principle of the above embodiments is as follows: When wiring is required for the instrument on cabinet door 2, connect one end of the wire to the instrument, then pull the positioning rod 7 through the collar 17 to move the positioning rod 7 out of the positioning hole 8, thus removing the positioning restriction on the pressure plate 5. Afterwards, open the pressure plate 5 and insert the wires into the cable tray 4 one by one. After the wires are connected, close the pressure plate 5. The pressure plate 5 and the limiting protrusion 6 will further restrict the wires in the cable tray 4, preventing them from easily falling out. When the pressure plate 5 rotates to close, the inclined surface of the positioning rod 7 will squeeze the positioning rod 7, causing it to move outwards. When the positioning rod 7 moves outward, it stretches the spring 9. When the pressure plate 5 is fully closed, the spring 9 applies a reaction force to the positioning rod 7, causing the positioning rod 7 to automatically move back and insert into the positioning hole 8, thus positioning the pressure plate 5 again. After the wire is inserted into the cable tray 4, its lower end passes through the cable tray 13 below to further organize the wire, making the wire more neat and tidy. Finally, the wire passing through the cable tray 13 can be connected to the internal components of the low-voltage cabinet. The cable tray 13 can be positioned by the positioning bolt 16, which makes it easy to adjust the position of the cable tray 13 as needed.
