Abstract
Description
Technical Field
[0001] This utility model relates to an electrical cabinet, and more particularly to an electrical cabinet with a low inductance wiring structure, belonging to the technical field of electrical cabinets. Background Technology
[0002] In the actual operation of electrical cabinets, the presence of inductive reactance is like a hidden "circuit current", which constantly threatens the stability and safety of the system. When the contactor disconnects inductive loads such as motors, the back electromotive force generated by the sudden change in current will form an extremely high peak voltage, which will break through the contact insulation like a sharp blade and cause an electric arc. At best, it will burn the contacts and cause poor contact, and at worst, it will cause a chain of damage to adjacent electronic components.
[0003] Currently, during the use of electrical cabinets, wiring and electrical appliance installations are located on the inner end face of the cabinet. The presence of electrical components can cause some interference to the straight connection of wires, resulting in some bending or even coiling of the wires, which lengthens the wires and increases the inductive reactance.
[0004] To address this issue, an electrical cabinet with a low inductance wiring structure was designed. Utility Model Content
[0005] The main objective of this invention is to provide an electrical cabinet with a low inductance wiring structure to solve the problems mentioned in the background art.
[0006] The objective of this utility model can be achieved by adopting the following technical solution:
[0007] An electrical cabinet with a low inductance wiring structure includes a cabinet body, cabinet doors are hinged to both the front and rear ends of the cabinet body, a partition is vertically fixed inside the cabinet body, a support rod is vertically slidably arranged on the side of the partition near the front end of the cabinet body, and the support rod is parallel to the horizontal plane, and a positioning mechanism is provided at both ends of the support rod.
[0008] The partition has wire slots evenly spaced along its height, and slots are evenly spaced on the side of the partition away from the support rod. A wire baffle is inserted into the slot.
[0009] Preferably, there are four sets of support rods, and the adjacent support rods are parallel to each other, with positioning holes opened on the outer side of each support rod.
[0010] Preferably, the bottom of the wire channel is curved on the side away from the support rod, and the wire channel is located in the middle of the adjacent slots.
[0011] Preferably, the wire stop plate includes a groove and a plug. The groove is formed on one side of the wire stop plate, and the plug is symmetrically arranged on the side of the wire stop plate away from the groove. The plug is inserted into the inside of the slot.
[0012] Preferably, the front end of the groove is rectangular, the rear end of the groove is circular, and the width of the front end of the groove is smaller than the width of the rear end.
[0013] Preferably, the positioning mechanism includes a vertical plate, a strip groove, a slot, a mounting hole, a slide rod, a positioning block, and a pull block. The vertical plate is vertically installed on both sides inside the cabinet. The spacing between the vertical plate and the partition is the same as the width of the support rod. A strip groove is opened along the height direction on the vertical plate. Slots are symmetrically opened on both sides of the strip groove. A mounting hole is opened at the end of the support rod. A slide rod is slidably installed inside the mounting hole. The slide rod passes through the inside of the strip groove. Positioning blocks that are inserted into the slots are symmetrically arranged on both sides of the slide rod. A pull block is fixed at the end of the slide rod away from the mounting hole.
[0014] Preferably, a spring is installed between the ends of the slide rod and the support rod, and the two ends of the spring are fixedly connected to the ends of the slide rod and the mounting hole, respectively.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This utility model features a vertically installed partition inside the cabinet, with doors at both the front and rear ends. One side of the partition has a sliding support rod for installing electrical components. The partition has evenly spaced wire slots, and the other side has a wire baffle to separate and limit the wires. This allows wiring and electrical component installation within the cabinet to be carried out on opposite sides of the partition, preventing electrical components from obstructing straight wire connections and avoiding redundant bending. Wires are prioritized for straight or shortest paths, significantly reducing inductive reactance, improving system stability, and minimizing overvoltage, interference, and losses caused by inductive reactance.
[0017] 2. This utility model uses a positioning mechanism composed of a vertical plate, a strip groove, a slot, a mounting hole, a spring, a sliding rod, a positioning block, and a pull block. This mechanism can adjust the installation position of electrical components during use, minimize the distance between electrical components, reduce the length of the wires between electrical components, further reduce inductive reactance, and improve practicality.

[0031] Example 1
[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes an electrical cabinet with a low inductance wiring structure, including a cabinet body 1. Cabinet doors 2 are hinged to both the front and rear ends of the cabinet body 1. A partition 3 is vertically fixed inside the cabinet body 1. A support rod 4 is vertically slidably arranged on the side of the partition 3 near the front end of the cabinet body 1. The support rod 4 is parallel to the horizontal plane. Positioning mechanisms 5 are provided at both ends of the support rod 4.
[0033] The partition 3 has wire through grooves 6 evenly distributed along its height direction, and slots 7 are evenly distributed on the side of the partition 3 away from the support rod 4. A wire baffle 8 is inserted and installed inside the slot 7.
[0034] During the assembly of the electrical cabinet, the spacing of the electrical components is adjusted according to the installation plan to ensure that the electrical components have the shortest distance without affecting the installation. Then, the electrical components are fixed on the support rod 4. Then, the wires are installed on the electrical components. The wires are then passed through the wire channel 6 and into the back of the partition 3. The wires are pulled straight into the electrical components to be installed. Then, the wires are passed forward from the inside of the wire channel 6 and connected. The wires connect the electrical components in a straight line, which is the shortest path and can significantly reduce the inductive reactance during use.
[0035] Example 2
[0036] The solution in Example 1 will be further described below with reference to its specific working method.
[0037] like Figure 1 As shown, in a preferred embodiment, based on the above method, four sets of support rods 4 are further provided, and adjacent support rods 4 are parallel. Positioning holes are opened on the outer side of each support rod 4. Electrical components are fixed to the support rods 4 by bolts. The arrangement of multiple sets of support rods 4 makes the installation position of electrical components more flexible. The support rods 4 are made of aluminum alloy 6061-T6, with a cross-sectional size of 20mm×10mm, a single rod load capacity of ≥10kg, a positioning hole spacing of 50mm, a bolt specification of M4, and a torque requirement of 2-2.5N・m.
[0038] like Figure 3 As shown, in a preferred embodiment, based on the above method, the bottom of the wire channel 6 is further curved on the side away from the support rod 4. The wire channel 6 is located in the middle of the adjacent slot 7. The curved design of the bottom of the wire channel 6 can reduce the damage to the wire caused by the right angle edge when connecting the wires. The edge of the wire channel 6 is pasted with a silicone rubber protective strip (1mm thick) with a Shore A hardness of 60-70 to reduce friction damage to the wires.
[0039] like Figure 3As shown, in a preferred embodiment, based on the above method, the wire baffle 8 further includes a groove 801 and a plug 802. The groove 801 is formed on one side of the wire baffle 8, and the plug 802 is symmetrically arranged on the side of the wire baffle 8 away from the groove 801. The plug 802 is inserted into the inside of the slot 7. The surface of the plug 802 is provided with a barbed protrusion (0.3mm in height and 45° in angle), which cooperates with the groove of the inner wall of the slot 7. It requires a pulling force of 5-8N to pull it out. After the wire passes through the back of the partition 3, it can be inserted into different grooves 801 to separate different wires for easy maintenance.
[0040] like Figure 3 As shown, in a preferred embodiment, based on the above method, the front end of the groove 801 is rectangular, the rear end of the groove 801 is circular, and the width of the front end of the groove 801 is smaller than the width of the rear end. The front end of the groove 801 has a smaller opening, while the rear end has a larger capacity, which can limit the movement of multiple sets of wires with the same path, making it more convenient to use.
[0041] like Figure 4 As shown, in a preferred embodiment, based on the above method, the positioning mechanism 5 further includes a vertical plate 501, a strip groove 502, a slot 503, a mounting hole 504, a sliding rod 506, a positioning block 507, and a pull block 508. The vertical plate 501 is vertically arranged on both sides inside the cabinet 1. The distance between the vertical plate 501 and the partition 3 is the same as the width of the support rod 4. A strip groove 502 is formed on the vertical plate 501 along the height direction, and slots 503 are symmetrically formed on both sides of the strip groove 502. 3. The end of the support rod 4 is provided with a mounting hole 504. A slide rod 506 is slidably arranged inside the mounting hole 504. The slide rod 506 passes through the inside of the strip groove 502. The width of the strip groove 502 is 0.5mm larger than the diameter of the slide rod 506. Positioning blocks 507 that are inserted into the slot 503 are symmetrically arranged on both sides of the slide rod 506. The slot 503 is 3mm deep and the insertion depth of the positioning block 507 is ≥2.5mm. A pull block 508 is fixed at the end of the slide rod 506 away from the mounting hole 504.
[0042] During installation, according to the installation plan of the electrical components, first pull the slide rod 506 outward, and the positioning block 507 is pulled out from the inside of the slot 503. Then, control the support rod 4 to slide vertically on the outer surface of the partition 3 to adjust the position of the support rod 4. Then, insert the positioning block 507 on the slide rod 506 into the inside of the slot 503 to position the support rod 4. Finally, install and fix the electrical components.
[0043] like Figure 4As shown, in a preferred embodiment, based on the above method, a spring 505 is further installed between the end of the slide rod 506 and the end of the support rod 4, and the two ends of the spring 505 are fixedly connected to the ends of the slide rod 506 and the mounting hole 504, respectively. Due to the use of the spring 505, the slide rod 506 will not slide out of the mounting hole 504 during the pulling process, and the positioning stability of the slide rod 506 during use is guaranteed.
[0044] Example 3
[0045] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.
[0046] During installation, according to the installation plan of the electrical components, pull the pull block 508 outward, causing the slide rod 506 to move outward against the elastic force of the spring 505, so that the positioning block 507 disengages from the slot 503. Due to the limitation of the spring 505, the slide rod 506 will not slide out of the mounting hole 504. Then, control the support rod 4 to slide vertically on the outer surface of the partition 3 to adjust the position of the support rod 4. Then release the slide rod 506. Under the reset action of the spring 505, the positioning block 507 on the slide rod 506 is inserted back into the slot 503 to position the support rod 4. Then, install and fix the electrical components. Then, install the wires onto the electrical components. Then, pass the wires through the wire groove 6 into the back of the partition 3. Pull the wires straight into the electrical components to be installed. At the same time, the wires pass through the inside of the groove 801 to separate and limit the wires. Then, pass them forward from the inside of the wire groove 6 and connect them. The electrical components are connected in a straight line, which is the shortest path and can significantly reduce the inductive reactance during use.
[0047] The above description is only a further 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 scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
