[0002] In the field of power distribution, distribution boxes are the core equipment for power distribution. The installation stability, heat dissipation efficiency, and wiring convenience of their internal components directly affect the reliability and maintenance costs of the system. Traditional distribution boxes generally have the following bottlenecks: Existing distribution boxes mostly use standard rails to fix components such as air switches, and installation is achieved by connecting the clips at the bottom of the components to the rails. However, this method has the following problems: inconvenient assembly and disassembly: when disassembling, the clips need to be forcibly pulled from below, which is especially difficult to operate in a small space and can easily cause damage to the components or rails; lack of versatility: the rail size is fixed and cannot adapt to components of different widths or back structures, and the rail type needs to be frequently changed; poor fixing stability: the single clip fixation can easily cause the component to loosen due to vibration, posing a risk of falling off.

DETAILED DESCRIPTION

[0022] In the description of the present invention, it should be understood that the terms "center," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, indicating positions or location relationships, are based on the positions or location relationships shown in the accompanying drawings and are intended only to facilitate description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figures 1 to 7 , to solve the problem of making the air switch easy to remove from the back panel.

[0024] The bus 101 is arranged behind the track plate 11, and multiple fixing devices are arranged on the track plate 11. Each fixing device includes two longitudinally arranged clips 12 that are slidably connected to the track plate 11. Two first compression springs are fixed between the two clips 12. Each clip 12 is provided with a slot 202. A pressing block 201 is provided at both ends of each clip 12. Each set of fixing devices also includes two transversely arranged heat conducting plates 102 that are slidably connected to the track plate 11. A first tension spring is provided between the two corresponding heat conducting plates 102.

[0025] Track plate 11 is made of aluminum alloy, ensuring a lightweight design. Its surface is anodized for improved corrosion resistance. Busbar 101 is made of copper and coated with an insulating layer. It is used for collecting and distributing electricity and is secured to track plate 11 via rubber connectors. The longitudinal part of the track plate 11 is used to fix it to the distribution box, and the clip 12 is arranged in parallel and slidably connected to the track plate 11. An elastic support structure is formed between the two corresponding clips 12 by two first compression springs, so that it can be fixed from the back side of the air switch to the outside. Compared with the traditional fixing method, it is fixed to the metal bar by the clip on the air switch, but when removing it with this method, it is necessary to pull the clip on the air switch from below, which is inconvenient to disassemble when the installation environment is small. In the present invention, the worker presses the two corresponding pressing blocks 201 on either side by hand, thereby bringing the two clips 12 closer and separating the two heat conducting plates 102. Then, the air switch is fixed by the first compression spring and the slot 202, so as to achieve the purpose of facilitating the disassembly of the air switch. At the same time, the heat conducting plates 102 on both sides clamp the air switch from both sides through the first tension spring, further increasing the stability of the fixation. The length of the clip 12 is set to be longer, so that it can meet the fixing effect of air switches of different widths. At the same time, the first compression spring between the two corresponding clips 12 pushes the clip 12 outward, so that it can act on switches with different back sizes without replacing different mounting rails, making the application scenarios of the present invention wider.

[0026] like Figure 6 and Figure 7 , to increase the cooling effect after fixation.

[0027] A heat dissipation strip is provided on one side of each heat conducting plate 102 away from the air switch.

[0028] Since the heat conducting plates 102 on both sides fix the air switch from both sides, and the contact area with the air switch is large, in order to avoid affecting the heat dissipation effect of the air switch, a heat dissipation strip is provided on the outside of the heat conducting plates 102. At the same time, the heat conducting plates 102 and the heat dissipation strip are made of good thermal conductive materials. When the heat conducting plates 102 on both sides are stretched and squeezed on both sides of the air switch by the first tension spring, the heat conducting plates 102 are tightly attached to the air switch, thereby transferring the heat in the air switch to the heat dissipation strip, and dissipating it outward through air convection. The heat dissipation strip increases the contact area between the air switch and the air, thereby increasing the heat dissipation effect.

[0029] like Figure 8 , so that the air switch can be easily installed between the two card strips 12.

[0030] A long oblique block 203 is provided at the front end slot 202 of each clamping strip 12 .

[0031] During installation, since the air switch will block the line of sight, in order to prevent the rear of the air switch from being unable to be completely inserted into the slot 202, a long inclined block 203 is provided. After stopping pressing the two pressing blocks 201, pressure is applied to the rear side of the air switch so that the inclined block 203 can help the rear of the switch to be inserted into the slot 202. The connection between the inclined block 203 and the slot 202 has a smooth transition, avoiding stress concentration that damages the air switch, and thus preventing the rear of the air switch from warping up and causing unstable fixation, thereby reducing the difficulty of assembly.

[0032] like Figures 7 to 9 , in order to solve the problem of synchronous movement of the card strip 12 and the heat conducting plate 102, thereby reducing the number of installation steps.

[0033] Each set of fixing devices also includes two mutually hinged rotating rods 204, the middle parts of the two rotating rods 204 are rotatably connected to the track plate 11, two protrusions 205 are symmetrically provided on each rotating rod 204, each slider 206 is rotatably connected to the corresponding protrusion 205, and each clip 12 is slidably connected to two sliders 206 located in the same direction on the two corresponding rotating rods 204.

[0034] When the pressing block 201 is pressed to make the two card strips 12 approach each other, the slider 206 is driven to push the boss 205, thereby causing the two rotating rods 204 to rotate relative to each other. At this time, the two sliders 206 slide synchronously to both sides, and at the same time, the boss 205 and the slider 206 rotate relative to each other to avoid jamming, thereby ensuring that the rotating rod 204 can rotate normally. When the upper and lower ends of the rotating rod 204 contact the two heat conducting plates 102 respectively, as the rotating rod 204 continues to rotate, the two heat conducting plates 102 are pushed to both sides, causing the two to move away from each other. Similarly, when the first compression spring drives the two card strips 12 away, the distance between the two sliders 106 becomes smaller, causing the rotating rod 204 to rotate in the opposite direction, thereby achieving the purpose of synchronous movement of the two card strips 12 and the heat conducting plates 102.

[0035] Furthermore, the coordinated movement of the rotating rod 204, the boss 205, and the slider 206 ensures the synchronization of the movement of the two clips 12, enabling synchronized opening and closing of the two clips 12 and preventing vertical deviation of the two clips 12 slidably connected to the track plate 11. Simultaneously, pressing only one side of the pressing block 201 distributes the pressure on the clips 12 via the rotating rod 204, preventing excessive friction between the clips 12 and the track plate 11 caused by excessive pressure on one side, which would increase the difficulty of opening and closing the clips with one hand.

[0036] like Figure 9 , in order to solve the limitation problem between the rotating rod 204 and the heat conducting plate 102.

[0037] Both ends of each rotating rod 204 are rotatably connected to a guide wheel 207 , and the upper and lower ends of each heat conducting plate 102 are fixedly connected to two guide wheel grooves 103 , and each guide wheel 207 is rollingly fitted in the corresponding guide wheel groove 103 .

[0038] When the rotating rod 204 rotates, it drives the guide wheel 207 to move into the guide wheel groove 103. This causes the rotating rod 204 to push the heat conducting plate 102, changing the motion between the two from sliding friction to rolling friction, thereby reducing energy loss. The highest point of the two guide wheel grooves 103 is the same as the highest point of the guide wheel 207 when the two hinged rotating rods 204 are close to each other. This ensures that the rotating rod 204 can immediately drive the heat conducting plate 102 to move when it rotates. This prevents the two first tension springs from pulling the heat conducting plate 102 too close together when a thin single-phase air switch is installed in the fixture, preventing the rotating rod 204 from being able to push the heat conducting plate 102 to move.

[0039] like Figure 10 and Figure 11 , to solve the problem of quick wiring of air switches.

[0040] The push plates 13 are slidably connected to the track plate 11 . Each push plate 13 is located above a corresponding fixing device. Three wires 304 are fixed to the push plates 13 . The other end of each wire 304 is slidably connected to the corresponding bus bar 101 .

[0041] After installing the air switch, push the push plate 13 to drive the wire 304 thereon to move downward, so that the wire 304 is inserted into the wiring port of the air switch, so that three wires can be connected at the same time. The same is true when disassembling, thereby increasing the disassembly and assembly speed of the air switch.

[0042] Preferably, the push plate 13 is configured as three slides that can slide relative to each other, each wire 304 is fixed to a slide, and the slides can be locked. In this way, the distance between each wire 304 can be adjusted, thereby meeting the installation requirements of air switches with different wiring port spacing.

[0043] like Figure 10 and Figure 11 , in order to solve the problem of unstable connection between wire 304 and air switch.

[0044] Each push plate 13 is slidably connected to a pressure plate 301, a second tension spring is fixed between the pressure plate 301 and the corresponding push plate 13, three rubber blocks 302 are fixed to the pressure plate 301, a pressure pin 303 is slidably connected to each rubber block 302, and a second compression spring is provided between the pressure pin 303 and the corresponding rubber block 302.

[0045] When the push plate 13 is moved downward, the pressure plate 301 is pulled outward. When the wire 304 moves into the air switch, the pressure plate 301 moves synchronously to the fixed position at the wire interface on the air switch. At this time, the pressure plate 301 is released, and the second tension spring drives the rubber block 302 and the pressure pin 303 to move synchronously to the fixed position. At this time, the rubber block 302 is pressed onto the air switch by the second compression spring, and then the internal pressure pin 303 is pushed by the second compression spring to compress the wire 304, thereby increasing the stability of the connection between the wire 304 and the air switch.

[0046] like Figure 10 and Figure 11 , in order to solve the problem of contact stability between the wire 304 and the bus bar 101.

[0047] Two conductive plates 305 are fixedly connected to each conductor 304 . A sliding groove is provided on the busbar 101 , and each conductive plate 305 is slidably connected in the corresponding sliding groove.

[0048] The surface of the bus 101 is provided with an insulating coating, so the slide groove opened on the bus 101 can destroy the insulating layer, and the part of the conductive sheet 305 in contact with the slide groove can conduct electricity. The outer side of each conductive sheet 305 is coated with an insulating coating. Therefore, when the wire 304 moves in the bus 101, the contact area with the bus 101 is too small, which will cause the local temperature to be too high during operation, creating a danger. Therefore, the conductive sheet 305 is provided to increase the contact area with the bus 101 and increase the stability of the connection between the wire 304 and the bus 101.

[0049] like Figure 10 and Figure 11 , in order to achieve the purpose of protecting the chute part.

[0050] A protective plate 306 is fixedly connected to the top of each conductive sheet 305 , and the length of the protective plate 306 is equal to the length of the sliding groove.

[0051] Each conductive sheet 305 is covered with a protective plate 306 made of insulating PVC. The plate 306 is the same length as the chute and wide enough to cover both sides of the conductive sheet. The plate 306 is secured to the top of the busbar with snaps, and its edges seamlessly align with the inner walls of the chute. Raised ribs are located on the bottom of the plate 306, creating an air gap with the top of the conductive sheet to prevent accidental contact. The plate 306 isolates the conductive area from the external environment, preventing foreign objects from entering and causing short circuits.

[0052] like Figure 12 , a distribution box used in conjunction with the distribution box panel.

[0053] It includes a box body 14, a fixing rod 401 is fixed inside the box body 14, the track plate 11 is fixed to the fixing rod 401, fixing blocks 402 are fixed on both sides of the box body 14, the fixing blocks 402 are insulators, the bus 101 is fixed between the fixing blocks 402 on both sides, and a dustproof wire hole 403 is provided on one side of the box body 14.

[0054] The fixed track plate 11 is fixed on the fixed rod 401, and the fixed blocks 402 on both sides are used to fix the bus 101. The fixed blocks 402 are made of epoxy resin to achieve electrical isolation. The wires connected to the outlet end of each air switch pass through the dustproof wire hole 403. A rubber sealing ring is set at the dustproof wire hole 403 to prevent dust from entering the distribution box and affecting heat dissipation.
