Description

Technical Field

[0001] This invention relates to the field of new energy battery manufacturing equipment technology, specifically to a pressure locking component, an electrical component mounting plate, and a power distribution cabinet. Background Technology

[0002] In electrical control systems, electrical components such as circuit breakers and relays typically need to be mounted on dedicated mounting rails. Existing mounting methods often involve directly snapping the components onto the rail using their own clips or tightening them with simple screws. However, these existing technologies have the following problems: First, traditional clip-on connections inevitably introduce clearances. During long-term operation or when subjected to external vibrations, components are prone to slight displacement on the rail, potentially leading to loosening and detachment. These clearances also amplify the damage caused by vibrations to the components' internal structure. Second, existing locking devices usually rely solely on spring force. Over time, the springs fatigue and fail, resulting in reduced locking force, and they lack an effective mechanism for absorbing vibration energy. Third, the wires of electrical components often lack effective securing devices, allowing them to sway with equipment vibrations and causing poor contact. Finally, when repairing or replacing a component in a closely packed group of components, it is often necessary to disassemble multiple adjacent components, resulting in cumbersome operations and low maintenance efficiency.

[0003] Therefore, there is an urgent need for an electrical component mounting plate and locking assembly that can achieve seamless integrated installation, has good seismic performance, and is easy to maintain. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a pressure-locking component, an electrical component mounting plate, and a power distribution cabinet to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pressure locking assembly, comprising an angled frame and a slide rod, one end of the slide rod passing through the angled frame, the other end of the slide rod being fixedly connected to a pressure part, and a positioning ring being fixedly connected to the outside of the slide rod;

[0006] The pressing part includes an adjusting box and an adjusting tube. One end of the adjusting tube is slidably connected to the inside of the adjusting box, and the other end is located outside the adjusting box and is fixedly connected to an elastic pad. An elastic layer and a second magnetic plate are provided inside the adjusting tube. A first magnetic plate is provided inside the adjusting box. The magnetic plates on adjacent sides of the first and second magnetic plates have the same magnetism. The elastic layer is provided between the first and second magnetic plates.

[0007] As a further preferred embodiment, a guide slider is fixed to the outside of the adjusting tube, and a guide groove adapted to the guide slider is provided inside the adjusting box.

[0008] As a further preferred embodiment, an electrical component mounting plate includes the aforementioned pressing and locking assembly, and further includes a mounting rail, a positioning part, and a positioning assembly;

[0009] The mounting track is provided with locking strips at both the upper and lower parts, and the upper locking strip has a hollow positioning strip on the side facing away from the mounting track; the mounting track is provided with mounting brackets at both the top and bottom, and each mounting bracket has the positioning part inside;

[0010] The pressure locking assembly includes an angled frame and a sliding rod. One end of the sliding rod passes through the angled frame, and the other end is fixedly connected to a pressure part. A positioning ring is fixedly connected to the outside of the sliding rod. The pressure part includes an adjusting box and an adjusting tube. One end of the adjusting tube is slidably connected to the inside of the adjusting box, and the other end is fixedly connected to an elastic pad. An elastic layer and a second magnetic plate are disposed inside the adjusting tube. A first magnetic plate is disposed inside the adjusting box. The magnetic plates on adjacent sides of the first and second magnetic plates have the same magnetism. The elastic layer is disposed between the first and second magnetic plates.

[0011] The installation track has a positioning groove at one end away from the angle frame, and the positioning component is disposed in the positioning groove.

[0012] As a further preferred embodiment, both ends of the mounting track are fixed with mounting plates, the angled frame is rotatably connected to one of the mounting plates, and an adjustment groove is provided on the front part of the mounting track away from the positioning component, and the pusher is slidably connected inside the adjustment groove.

[0013] As a further preferred embodiment, the positioning part includes an elastic sleeve and a connecting shaft. The elastic sleeve is disposed outside the connecting shaft. At least two sets of protrusions are arranged in a corrugated pattern on the outside of the elastic sleeve. The gap between the at least two sets of protrusions is bullet-shaped. A cavity corresponding to the protrusions is disposed inside the elastic sleeve.

[0014] As a further preferred embodiment, the inner wall of the cavity is bonded with reinforcing ribs, and the reinforcing ribs are provided with a number of toothed grooves on the side adjacent to the elastic sleeve.

[0015] As a further preferred embodiment, the positioning assembly includes a positioning frame, two sets of parallel guide slide rods, and multiple pads. The positioning frame and the pads are slidably connected to the two sets of guide slide rods, and a buffer plate is provided between the sets of guide slide rods.

[0016] As a further preferred embodiment, the buffer plate is made of an elastic material that can undergo compression deformation under pressure, and the buffer plate extends out from inside the positioning groove.

[0017] As a further preferred embodiment, a power distribution cabinet includes the aforementioned electrical component mounting plate, characterized in that it further includes a power distribution cabinet body, wherein the electrical component mounting plate is mounted on the inner wall of the power distribution cabinet body.

[0018] This invention provides a pressure-locking assembly, an electrical component mounting plate, and a power distribution cabinet, which have the following advantages:

[0019] By configuring magnetic plates one and two in conjunction with the elastic layer, when the pressing part contacts the component and is compressed, the regulating tube retracts into the regulating box. During this process, the distance between magnetic plates one and two decreases. Due to the repulsion of like magnetic poles, the repulsive force between them increases non-linearly. Combined with the physical deformation of the elastic layer, a dual adaptive locking mechanism of magnetic force + elastic force is formed. This mechanism not only provides continuous and constant pressure on electrical components to prevent them from loosening, but also effectively absorbs external vibration energy, preventing electrical components from being displaced or damaged due to vibration, thus significantly improving the operational stability under complex working conditions.

[0020] In the connection structure between the mounting track and the components, a hollow positioning strip with a variable cross-section is used. When the components are rotated and snapped in, the positioning strip is squeezed and deformed, thereby tightly filling the tiny gap between the component clip and the track. This deformation fit makes the components and the mounting track form an integrated structure, effectively solving the contact gap problem in the traditional clip installation method, greatly reducing the amplification effect of vibration in the transmission process, and further protecting the components from damage.

[0021] The positioning part adopts an elastic sleeve design with corrugated protrusions and internal cavities. Utilizing the elastic deformation capability of the elastic sleeve, when wires of different diameters are pressed into the gap of the protrusion, the gap is squeezed and deformed. Combined with the toothed groove structure on the internal reinforcing ribs, it can automatically shrink and tightly wrap the wires. This structure can adapt to wires of different specifications without additional tools, and it wraps tightly to prevent the wires from loosening and falling off, thereby improving the standardization and safety of wiring.

[0022] The design of the pads and buffer plates in the positioning assembly allows for flexible adaptation to the number of components installed. The pressing position of the positioning frame can be adjusted by adding or removing pads according to the actual number of components installed, achieving initial positioning of components arranged in different lengths. Importantly, during later maintenance or replacement of individual components, the pads can be removed simply by pulling out the buffer plate, eliminating the need to disassemble the entire device or rewire, greatly reducing maintenance difficulty and improving work efficiency.

Detailed Implementation

[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The following disclosure provides many different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0036] like Figure 4-6 As shown, this embodiment of the invention provides a pressing and locking assembly, including an angled frame 200 and a slide bar 201. One end of the slide bar 201 passes through the angled frame 200, and the other end of the slide bar 201 is fixedly connected to a pressing part. A positioning ring 206 is fixedly connected to the outside of the slide bar 201.

[0037] The pressing part includes an adjusting box 205, an adjusting tube 204 is slidably connected inside the adjusting box 205, an elastic pad 203 is provided on the side of the adjusting tube 204 away from the adjusting box 205, an elastic layer 209 and a second magnetic plate 210 are provided inside the adjusting tube 204, a first magnetic plate 207 is provided inside the adjusting box 205, the first magnetic plate 207 and the second magnetic plate 210 have the same magnetism on the adjacent side, and the elastic layer 209 is provided between the first magnetic plate 207 and the second magnetic plate 210.

[0038] In this embodiment, the position of the pressing part can be adjusted by pushing the positioning ring 206 through the angle bracket 200. Then, the elastic pad 203 will press against one side of the component 102. After the pressing part presses against the component 102, during the process of the adjusting tube 204 moving into the adjusting box 205, the magnetic plate 1 207 will squeeze the elastic layer 209. At the same time, due to the decrease in distance between the magnetic plate 1 207 and the magnetic plate 210, the repulsive force between them will increase, so that several groups of components 102 are installed stably on the mounting track 100, and the components 102 are prevented from moving due to interference from external factors.

[0039] It should be noted that one side of the elastic layer 209 is bonded to the magnetic plate 210.

[0040] Furthermore, a guide slider 208 is fixed to the outside of the adjusting tube 204, and a guide groove adapted to the guide slider 208 is opened inside the adjusting box 205.

[0041] Specifically, after the elastic pad 203 presses against the component 102, the continuous pressure will cause the regulating tube 204 to slide into the regulating box 205. Through the cooperation of the guide slider 208 and the guide groove, the regulating tube 204 moves horizontally.

[0042] It is understandable that multiple sets of guide sliders 208 are provided on the outside of the regulating tube 204, and corresponding guide grooves are also provided on the inner wall of the regulating box 205.

[0043] like Figure 1-6 As shown, an electrical component mounting plate includes the aforementioned pressure locking assembly and a mounting rail 100. Mounting brackets 101 are provided at both the top and bottom of the mounting rail 100. Positioning parts are provided inside the mounting brackets 101. A positioning groove is provided at the front end of the mounting rail 100 opposite to the angled frame 200. A positioning assembly is provided inside the positioning groove. Locking strips 103 are provided at both the top and bottom of the mounting rail 100. A hollow positioning strip 104 is provided on the side of the upper locking strip 103 opposite to the mounting rail 100. The locking strip 103 and the positioning strip 104 are used to support and position the component 102.

[0044] In this embodiment, component 102 is mounted on mounting track 100 via buckles and clips 103. Meanwhile, the hollow positioning strip 104 deforms under pressure, and its cross-section becomes trapezoidal. Through the deformed positioning strip 104, component 102 can be integrated with mounting track 100, thereby improving the installation stability of component 102 and reducing the impact of vibration on component 102.

[0045] Specifically, the positioning strip 104 is inserted into the upper buckle of the component 102, and then the component 102 is rotated so that the lower buckle locks the lower strip 103. While rotating, the position of the upper buckle is adjusted to compress and deform the positioning strip 104, so that the component 102 and the mounting track 100 are completely integrated. This avoids the contact gap that exists in conventional buckles, which amplifies the vibration and damages the component 102 during vibration.

[0046] In this embodiment, a nut is also provided on the outside of the slide bar 201, and the position of the angle bracket 200 is initially locked by the nut and the positioning ring 206.

[0047] Furthermore, mounting plates are fixed at both ends of the mounting track 100, the angle bracket 200 is rotatably connected to a set of mounting plates, and an adjustment groove is provided at the front of the mounting track 100 on the side away from the positioning component, and the pusher 202 is slidably connected inside the adjustment groove.

[0048] Specifically, rotating the angle bracket 200 will compress the positioning ring 206, causing the pressing part to continuously move closer to the component 102, eventually pressing against the component 102 and locking the component 102.

[0049] In this embodiment, the positioning part includes an elastic sleeve 300 and a connecting shaft 301. The elastic sleeve 300 is disposed outside the connecting shaft 301. At least two sets of protrusions are arranged in a corrugated pattern on the outside of the elastic sleeve 300. The gap section of the at least two sets of protrusions is bullet-shaped. A cavity 302 corresponding to the protrusions is disposed inside the elastic sleeve 300.

[0050] Furthermore, the inner wall of the cavity 302 is bonded with reinforcing ribs 303, and a number of toothed grooves 304 are provided on the side of the reinforcing ribs 303 adjacent to the elastic sleeve 300.

[0051] Specifically, when several sets of components 102 are installed on the mounting track 100, the wires on the components 102 are placed in the gap between the two sets of protrusions. Since the elastic sleeve 300 is made of elastic material, the diameter of the wire itself will squeeze the inside of the gap, causing it to deform. At the same time, the opening of the toothed groove 304 becomes smaller due to the deformation. The gaps in the area above the guide will move closer to each other, so that the gaps will wrap around the wires and complete the positioning of the wires.

[0052] It should be noted that the area where the reinforcing rib 303 is provided with the toothed groove 304 is not bonded to the elastic sleeve 300.

[0053] like Figure 9 As shown, the positioning assembly includes a positioning frame 402, two sets of parallel guide slide rods 401, and several sets of pads 400. The pads 400 and the positioning frame 402 are slidably connected to the outside of the two sets of guide slide rods 401, and a buffer plate 403 is provided between the several sets of pads 400.

[0054] Furthermore, the buffer plate 403 is made of elastic material and can undergo compression deformation under pressure, with the buffer plate 403 extending out from inside the positioning groove.

[0055] Specifically, by adjusting the number of pads 400, the positioning frame 402 presses the components 102 to complete the initial positioning of several groups of components 102. After the rotating angle frame 200 completes the overall locking of several groups of components 102, the electrical component mounting plate is installed into the distribution cabinet by screws.

[0056] It should be noted that after the installation of the electrical component mounting plate is completed, if any group of components 102 needs to be repaired or replaced, the pads 400 can be removed one by one by pulling out the buffer plate 403. Then, the component 102 that needs to be replaced is removed. After replacement, the positioning frame 402 is pushed to fit against the component 102. After placing 2-3 sets of pads 400, the buffer plate 403 is placed into the positioning groove. Finally, the remaining pads 400 are added so that the positioning frame 402 has sufficient compressive force on the component 102.

[0057] like Figure 10As shown, this embodiment also provides a power distribution cabinet, including the above-mentioned electrical component mounting plate, characterized in that it further includes a power distribution cabinet body, and the electrical component mounting plate is installed on the inner wall of the power distribution cabinet body.

[0058] This invention discloses a pressure-locking assembly, an electrical component mounting plate, and a distribution cabinet. By incorporating two magnetic plates with opposite magnetic poles within the pressure-locking section, an elastic layer is formed. The combined effect of magnetic repulsion and elastic deformation achieves adaptive constant-pressure locking of components, effectively absorbing external vibration energy and preventing component loosening. Simultaneously, deformable hollow positioning strips on the mounting rail deform under pressure during installation, eliminating gaps between components and the rail, forming an integrated structure that significantly improves seismic stability. Furthermore, the elastic sleeve adaptively clamps the wires, and the positioning assembly allows for the addition or removal of pads, ensuring neat and secure wiring and enabling flexible adjustment of component mounting spacing. During maintenance, only the pads need to be removed for individual component disassembly and assembly, greatly reducing maintenance difficulty and improving work efficiency.
