Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinets, and in particular to an electrical component installation structure and a power distribution cabinet. Background Technology

[0002] A distribution cabinet is a device in a power system used to distribute, control, and protect electrical energy. By integrating various electrical components, the distribution cabinet can achieve functions such as rational distribution of electrical energy and control of circuit switching. Multiple electrical components in the distribution cabinet are installed inside the cabinet through an electrical component mounting structure. By adjusting the position of the electrical component mounting structure, the installation position of the electrical components in the distribution cabinet can be adjusted to achieve a rational layout of the electrical components.

[0003] Currently, a Chinese patent application with publication number CN 218216231 U and publication date of January 3, 2023 proposes an electrical component installation structure for a distribution box, including: a box body, an adjusting frame, and a movable frame. The movable frame is slidably installed on both sides of the inner wall of the box body, a support frame is fixedly installed on the inner side of the movable frame, an adjusting frame is fixedly installed on the support frame, and an installation frame is slidably installed on the outer side of the adjusting frame.

[0004] In use, the electrical components are mounted on the mounting bracket. By adjusting the mounting bracket to slide on the adjusting bracket, the adjusting bracket can move the electrical components horizontally. By adjusting the support bracket to slide on the movable bracket, the support bracket can move the adjusting bracket in the front-to-back direction.

[0005] Regarding the aforementioned technologies, since the installation position of electrical components can be flexibly adjusted with the mounting bracket, the connection position of the wires after the installation of electrical components is also more flexible. However, after installing a large number of electrical components, it will lead to messy and tangled wiring, which will affect subsequent circuit inspection and maintenance. Utility Model Content

[0006] In order to make the wiring of electrical components more organized after they are installed in the distribution cabinet, improve the cleanliness of the wiring in the distribution cabinet, and facilitate subsequent maintenance and repair, this utility model provides an electrical component installation structure and a distribution cabinet.

[0007] First aspect: This utility model provides an electrical component mounting structure, which adopts the following technical solution:

[0008] An electrical component mounting structure includes: a first slide rail, a second slide rail, and a mounting bracket. The first slide rail and the second slide rail are arranged in parallel. One end of the mounting bracket is slidably mounted on the first slide rail, and the other end of the mounting bracket is slidably mounted on the second slide rail. The first slide rail has a first conductive structure and a second conductive structure inside. The mounting bracket has a first terminal and a second terminal. The end of the mounting bracket slidably mounted on the first slide rail also has a connecting component. When the connecting component moves to a first position, the first terminal is connected to the first conductive structure. When the connecting component moves to a second position, the second terminal is connected to the second conductive structure.

[0009] By adopting the above technical solution, in use, firstly, select two mounting brackets according to the width of the electrical component, and adjust the distance between the two mounting brackets. Install the electrical component on the two mounting brackets. Secondly, after the electrical component is installed and fixed, slide and adjust the distance between the mounting brackets on the first and second slide rails and adjust the position of the electrical component. Finally, connect the first terminal on the mounting bracket to the positive terminal of the electrical component, and connect the second terminal on the mounting bracket to the negative terminal of the electrical component; or connect the first terminal on the mounting bracket to the negative terminal of the electrical component, and connect the second terminal on the mounting bracket to the positive terminal of the electrical component. Adjust the position of the connecting components, connect the first terminal connected to the electrical component to the first conductive structure, or connect the second terminal connected to the electrical component to the second conductive structure, and connect both the first and second conductive structures to the power supply to power the electrical component.

[0010] By adjusting the position of the mounting bracket, the electrical components can be flexibly adjusted. By connecting the first terminal of the mounting bracket to the first conductive structure or the second terminal to the second conductive structure, and connecting the first and second terminals to the electrical components, the electrical components can be powered on. Equipping each electrical component on the mounting bracket with a corresponding terminal helps to reduce the number of connection lines and makes the wiring of the electrical components clearer and neater.

[0011] Optionally, the connecting component includes a first conductive element, a second conductive element, a first fastener, and a second fastener. The first conductive element and the second conductive element are both disposed on the mounting bracket. The first conductive element is connected to the first terminal, and the second conductive element is connected to the second terminal. The first fastener is disposed on the first conductive element, and the second fastener is disposed on the second conductive element. When the first fastener is fixed to the first slide rail, the first conductive element is connected to the first conductive structure. When the second fastener is fixed to the first slide rail, the second conductive element is connected to the second conductive structure.

[0012] By adopting the above technical solution, both the first conductive structure and the second conductive structure are fixedly mounted on the first slide rail. The first fastener abuts the first conductive element against the first conductive structure, so that while the first conductive element is in contact with the first conductive structure, its position relative to the first slide rail is fixed. Since the first conductive element is connected to the first terminal, when the first conductive element is fixed relative to the first conductive structure, the first terminal is connected to the first conductive structure. The second fastener abuts the second conductive element against the second conductive structure, so that while the second conductive element is in contact with the second conductive structure, its position relative to the first slide rail is fixed. Since the second conductive element is connected to the second terminal, when the second conductive element is fixed to the second conductive structure, the second terminal is connected to the second conductive structure. In this way, by cooperating in setting the fasteners and conductive elements, while the mounting bracket is fixed to the first slide rail, the terminals on the mounting bracket can be connected to the conductive structure, facilitating the subsequent supply of power to electrical components through the terminals.

[0013] Optionally, the first fastener is a first fastening bolt, which is rotatably connected to the first conductive element and threadedly engaged with the mounting bracket; the second fastener is a second fastening bolt, which is rotatably connected to the second conductive element and threadedly engaged with the mounting bracket.

[0014] By adopting the above technical solution, the first fastener is threadedly engaged with the mounting bracket, so that when the first fastener and the mounting bracket rotate relative to each other, the first fastener can drive the first conductive element to abut against the first conductive structure, and while the first fastener and the first conductive structure are fixed, the first fastener and the first conductive structure can also make contact and communicate; the second fastener is threadedly engaged with the mounting bracket, so that when the second fastener and the mounting bracket rotate relative to each other, the second fastener can drive the second conductive element to abut against the second conductive structure, and while the second fastener and the second conductive structure are fixed, the second fastener and the second conductive structure can also make contact and communicate.

[0015] Optionally, the mounting bracket is further provided with a first isolation chamber and a second isolation chamber near the end of the first slide rail; the first conductive component is slidably disposed in the first isolation chamber, and a first partition is rotatably disposed at the opening of the first isolation chamber, the first partition covering the opening of the first isolation chamber under the action of an elastic component; the second conductive component is slidably disposed in the second isolation chamber, and a second partition is rotatably disposed at the opening of the second isolation chamber, the second partition covering the opening of the second isolation chamber under the action of an elastic component.

[0016] When the conductive component and the conductive structure are close together, in a humid environment, a large potential difference may cause discharge to occur even when they are not in contact. By adopting the above technical solution, when the conductive component is slidably stored in the isolation chamber, the partition, under the action of the elastic component, closes the end of the isolation chamber. This ensures that when the conductive component is not in contact with the conductive structure, the conductive component and the conductive structure are separated by the partition, reducing the probability of the conductive component and the conductive structure spontaneously connecting when not in operation.

[0017] Optionally, the first slide rail is further provided with an isolation part, which is disposed between the first conductive structure and the second conductive structure.

[0018] The first conductive structure and the second conductive structure are connected to the positive and negative terminals of the power supply, respectively. Moreover, the first conductive structure and the second conductive structure are close to each other, which may cause a discharge phenomenon between them, resulting in a short circuit. By adopting the above technical solution, the isolation part can isolate the first conductive structure and the second conductive structure, reducing the probability of a short circuit when the first conductive structure and the second conductive structure are connected.

[0019] Optionally, the mounting bracket is provided with a first sliding part and a second sliding part, the first sliding part and the second sliding part being respectively disposed on both sides of the isolation part.

[0020] By adopting the above technical solution, the first sliding part and the second sliding part are respectively disposed at both ends of the isolation part, so that the first sliding part and the second sliding part clamp and cooperate on both sides of the isolation part to form a slide rail, making the mounting bracket slide more stably and smoothly on the first slide rail.

[0021] Optionally, a hub assembly is also provided on the second slide rail, and the hub assembly is slidably disposed on the second slide rail.

[0022] The first and second conductive structures, in conjunction with the mounting bracket, provide power to electrical components while reducing wiring connections, making the wiring at the power supply end of the electrical components clearer and neater. By adopting the above technical solution, when organizing the wiring at the load end of the electrical components, the hub assembly is slid on the second slide rail to the position corresponding to the load end of the electrical components, and the wiring at the load end of the electrical components is collected and organized in the hub assembly, making the wiring at the load end of the electrical components clearer and neater, further improving the clarity and neatness of the wiring connections of the electrical components.

[0023] Optionally, the cable assembly includes a slider and a cable bundler, the cable bundler being rotatably mounted on the slider and secured by screws.

[0024] By adopting the above technical solution, the slider can drive the cable bundler to move and flexibly adjust the position of the cable bundler so that the position of the cable bundler corresponds to that of the electrical components; the rotating setting of the cable bundler can flexibly adjust the extension direction of the cable when the cable is concentrated and fixed in the cable bundler, making the cable layout clearer.

[0025] Secondly, this utility model provides a power distribution cabinet, which adopts the following technical solution:

[0026] A power distribution cabinet, characterized in that: it includes a cabinet body and an electrical component mounting structure as described in the first aspect, a power supply is provided inside the cabinet body, the first slide rail and the second slide rail are both installed inside the cabinet body, and the first conductive structure and the second conductive structure are both connected to the power supply.

[0027] By adopting the above technical solution and installing the aforementioned electrical component mounting structure in the cabinet of the distribution cabinet, the installation position of the electrical components in the cabinet can be flexibly adjusted, making the distribution of the electrical components more reasonable. Furthermore, by coordinating the first conductive structure, the second conductive structure, the connecting component, and the mounting bracket, and connecting the first and second conductive structures to the power supply, the wiring at the power supply end of the electrical components can be reduced, making the wiring connection inside the distribution cabinet more reasonable and clear. The setting of the hub component can organize the wiring at the load end of the electrical components, making the wiring in the distribution cabinet neater and clearer.

[0028] In summary, this utility model has at least one of the following beneficial technical effects:

[0029] A first conductive structure and a second conductive structure are set in the first slide rail, and the first conductive structure and the second conductive structure are respectively connected to the positive and negative terminals of the power supply. The positive and negative terminals of the power supply are directly integrated into the inside of the first slide rail, and are dynamically connected to the conductive structure in the slide rail through the terminals on the mounting bracket. This replaces the traditional independent busbar or cable power supply. When multiple electrical components are installed, the connection is made through the mounting bracket, which can effectively reduce the connection lines in the distribution cabinet, making the wiring connections in the distribution cabinet neater and clearer, and facilitating subsequent inspection and maintenance.

[0030] An isolation chamber with an elastic partition is provided at the end of the mounting bracket that is used to communicate with the conductive structure. When the conductive component is not in operation, it is stored in the isolation chamber and sealed by the elastic partition. When the conductive component is in operation, the partition is pushed open and it extends to contact the conductive structure, reducing the probability of conduction and discharge when the conductive component is not in operation.

[0031] The design employs a dual-rail system. The first rail carries the conductive structure and is equipped with an insulating isolation section, while the second rail is dedicated to the sliding of the hub assembly. This achieves physical separation of the power supply and load lines, making cable management more convenient and further increasing the neatness and clarity of the cable layout.

Detailed Implementation

[0041] The following combination Figures 1 to 8 The present invention will be described in further detail below.

[0042] This utility model discloses a power distribution cabinet. (Refer to...) Figures 1 to 5A power distribution cabinet mainly includes a cabinet body 500 and an electrical component mounting structure. The electrical component mounting structure mainly includes a first slide rail 100, a second slide rail 200, and a mounting bracket 300. The first slide rail 100 and the second slide rail 200 are installed parallel to each other inside the cabinet body 500. One end of the mounting bracket 300 is slidably mounted on the first slide rail 100, and the other end of the mounting bracket 300 is slidably mounted on the second slide rail 200. The first slide rail 100 is provided with a first conductive structure 110 and a second conductive structure 120. The first conductive structure 110 is connected to the positive terminal of a power supply 510 installed inside the cabinet body 500, and the second conductive structure 120 is connected to the negative terminal of the power supply 510 installed inside the cabinet body 500. The mounting bracket 300 is provided with a first end... Terminal 310 and second terminal 320, the first terminal 310 and the first conductive structure 110, the second terminal 320 and the second conductive structure 120 are all controlled to be connected by the connecting component 400; when the connecting component 400 moves to the first position, the first terminal 310 is connected to the first conductive structure 110, and at this time the first terminal 310 is connected to the positive terminal of the power supply 510; when the connecting component 400 moves to the second position, the second terminal 320 is connected to the second conductive structure 120, and at this time the second terminal 320 is connected to the negative terminal of the power supply 510. When the electrical component is installed on the mounting bracket 300, the electrical component can be powered by connecting the first terminal 310 and the second terminal 320 to the positive and negative terminals of the electrical component respectively with wires.

[0043] Reference Figure 3 The first slide rail 100 consists of a base plate and a cover plate, which are fixed together by bolts. The mounting bracket 300 is slidably disposed between the base plate and the cover plate. Specifically, the base plate has a "mountain" shaped structure, so that the protruding structure in the middle of the base plate forms an isolation part 101. The first conductive structure 110 and the second conductive structure 120 are respectively disposed in the grooves on both sides of the isolation part 101, and both the first conductive structure 110 and the second conductive structure 120 are fixed to the base plate of the first slide rail 100 by screws. The positive terminal of the power supply 510 in the cabinet 500 is connected to the first conductive structure 110 by a wire, and the negative terminal of the power supply 510 in the cabinet 500 is connected to the second conductive structure 120 by a wire, so that the first slide rail 100 can be used as a power supply terminal. After the mounting bracket 300 is installed on the base plate, the cover plate is placed on the mounting bracket 300, and the base plate and the cover plate of the first slide rail 100 are fixedly connected by screws.

[0044] Reference Figure 1 and Figure 2The second slide rail 200 is arranged in the cabinet 500 in a direction parallel to the first slide rail 100, and the second slide rail 200 is fixed on the cabinet 500 by screws. The second slide rail 200 is provided with a first slide groove for sliding connection with the mounting bracket 300 in the direction facing the first slide rail 100. The second slide rail 200 is provided with a second slide groove on the end face away from the outward. Both the first slide groove and the second slide groove are arranged along the length direction of the second slide rail 200.

[0045] Reference Figure 3 and Figure 4 The mounting bracket 300 has a first sliding portion 330 and a second sliding portion 340 at one end for sliding connection with the first slide rail 100. Both the first sliding portion 330 and the second sliding portion 340 are protruding structures on the surface of the mounting bracket 300, and there is a distance between the first sliding portion 330 and the second sliding portion 340. The end face of the mounting bracket 300 with the first sliding portion 330 and the second sliding portion 340 is set towards the bottom plate of the first slide rail 100, and the first sliding portion 330 is aligned with the bottom plate and a first conductive junction is installed. Align the second sliding part 340 with the groove of the structure 110 on the base plate, align the second sliding part 340 with the groove on the base plate where the second conductive structure 120 is installed, place the mounting bracket 300 on the base plate, and then fix the cover plate of the first slide rail 100 on the base plate. The mounting bracket 300 can then be slidably installed on the first slide rail 100. At this time, the first sliding part 330 and the second sliding part 340 are respectively located on both sides of the isolation part 101 on the base plate, so that the first sliding part 330 corresponds to the first conductive structure 110 and the second sliding part 340 corresponds to the second conductive mechanism.

[0046] Reference Figure 5 and Figure 6 A first isolation chamber 301 is provided on the first sliding part 330, and a second isolation chamber 302 is provided on the second sliding part 340. Both the first isolation chamber 301 and the second isolation chamber 302 penetrate the mounting frame 300 along the thickness direction of the mounting frame 300. The mounting frame 300 is also provided with two mounting slots, which are respectively connected to the first isolation chamber 301 and the second isolation chamber 302. A first terminal 310 is provided at the end of the mounting slot connected to the first isolation chamber 301, and a second terminal 320 is provided at the end of the mounting slot connected to the second isolation chamber 302. Two copper plates are installed in the two mounting slots respectively, so that the first terminal 310 is connected to the inside of the first isolation chamber 301 through the copper plates, and the second terminal 320 is connected to the inside of the second isolation chamber 302 through the copper plates.

[0047] To reduce the probability of discharge when the copper sheet in the first isolation chamber 301 is close to the first conductive structure 110, and the copper sheet in the first isolation chamber 302 is close to the first conductive structure 120, a first partition 303 is provided in the first isolation chamber 301, and a second partition 304 is provided in the second isolation chamber 302. The first partition 303 is rotatably installed in the first isolation chamber 301 by a torsion spring, and the first partition 303 isolates the copper sheet from the first conductive structure 110 in the first isolation chamber 301 under the action of the torsion spring. The second partition 304 is rotatably installed in the second isolation chamber 302 by a torsion spring, and the second partition 304 isolates the copper sheet from the second conductive structure 120 in the second isolation chamber 302 under the action of the torsion spring.

[0048] To reduce the operator's contact with the copper sheets extending from the first isolation chamber 301 and the second isolation chamber 302, an insulating baffle is provided in the mounting slot on the mounting bracket 300 for placing the copper sheets. The first terminal 310 and the second terminal 320 pass through the baffle and contact the copper sheets through threaded holes.

[0049] Reference Figure 6 In the mounting bracket 300, the first terminal 310 and the first conductive structure 110, and the second terminal 320 and the second conductive structure 120 are connected by a connecting component 400. The connecting component 400 includes a first conductive element 410, a second conductive element 420, a first fastener 430, and a second fastener 440. The first conductive element 410 is slidably disposed in the first isolation chamber 301 along the thickness direction. The first fastener 430 is a first fastening bolt, the end of which is an optical shaft. The optical shaft is rotatably connected to the first conductive element 410 through a bearing. The baffle of the mounting bracket 300 is provided with a threaded hole. The first fastening bolt can control the first conductive element 410 to slide along the depth direction of the first isolation chamber 301 by cooperating with the threaded hole. The corresponding second conductive element 420 is slidably disposed in the second isolation chamber 302. The second fastening bolt is disposed on the mounting bracket 300 and the second conductive element 420 in the same way as the first fastening bolt.

[0050] When the first fastening bolt is turned clockwise, it causes the first conductive element 410 to move closer to the first conductive structure 110, pushing open the first partition 303 in the first isolation chamber 301 and causing the first conductive element 410 to abut against the first conductive structure 110. At this time, the first conductive element 410 is fixed to the first conductive structure 110, and correspondingly, the mounting bracket 300 is fixed to the first slide rail 100. Since the first isolation chamber 301 is connected to the first terminal 310 through a copper sheet, the first conductive structure 110 is connected to the positive terminal of the power supply 510, allowing the first terminal 310 to pass through the first conductive structure 110. 10. The first conductive element 410 and the copper sheet are connected to the positive terminal of the power supply 510. At this time, the second conductive element 420 is stored in the second isolation chamber 302, and the second conductive element 420 is isolated from the second conductive structure 120 by the second partition 304. On the other hand, the first fastening bolt is rotated counterclockwise. The first fastening bolt drives the first conductive element 410 to move away from the first conductive structure 110 and gradually store it in the first isolation chamber 301. The first partition 303 closes the first isolation chamber 301 under the action of the torsion spring and forms an isolation between the first conductive element 410 and the first conductive structure 110.

[0051] The second fastening bolt and the second conductive element 420 are used in the same way as the first fastening bolt and the first conductive element 410, and the second terminal 320 is connected to the negative terminal of the power supply 510 through the second conductive structure 120, the second conductive element 420, and the copper sheet.

[0052] To facilitate the adjustment of the first fastener 430 and the second fastener 440, two slots are provided on the cover plate of the first slide rail 100. The two slots correspond to the positions of the first fastener 430 and the second fastener 440, respectively, and both slots are set along the length direction of the first slide rail 100.

[0053] In order to prevent the first conductive structure 110 and the second conductive structure 120 from being directly exposed inside the cabinet, the positions of the two slots should be staggered vertically from the first conductive structure 110 and the second conductive structure 120, and the corresponding first conductive component 410 and second conductive component 420 should be arranged in a stepped manner.

[0054] Reference Figure 7 and Figure 8The second slide rail 200 is also provided with a cable gathering assembly 210 in the second slide groove. Specifically, the cable gathering assembly 210 includes a slider 220 and a cable bundler 230. The slider 220 is slidably disposed in the second slide groove. The slider 220 is provided with a through hole. The cable bundler 230 is provided with a corresponding insertion hole. The outer wall of the insertion hole passes through the through hole of the slider 220, so that the cable bundler 230 can rotate relative to the slider 220. A fastening screw is used to pass through the insertion hole and the through hole at one time, and the fastening bolt is tightened. The fastening bolt is pressed against the bottom of the second slide groove to restrict the sliding of the slider 220 and the rotation of the cable bundler 230. In this embodiment, the cable bundler 230 can be an elastic band, a strap, a cable tie, or a clamping device that can clamp the cable.

[0055] In this embodiment, all non-conductive components are made of insulating materials, and components that need to be made of metal are coated with an insulating coating on the surface of the metal to reduce the risk of electric shock.

[0056] The implementation principle of the electrical component mounting structure and distribution cabinet of this utility model embodiment is as follows: In use, first select two mounting brackets 300, and based on the width of the electrical component, install the electrical component on the two mounting brackets 300. Then, move the mounting bracket 300 to a suitable position on the first slide rail 100. Adjust the first fastening bolt in the connecting component 400 on one mounting bracket 300 to connect the first terminal 310 to the first conductive structure 110 in the first slide rail 100, so that the first terminal 310 is connected to the positive terminal of the power supply 510. Adjust the other mounting bracket... The second fastening bolt in the connecting assembly 400 on the frame 300 connects the second terminal 320 to the second conductive structure 120 in the first slide rail 100, so that the second terminal 320 is connected to the negative terminal of the power supply 510. Then, the first terminal 310 is connected to the positive terminal of the power supply end of the electrical component, and the second terminal 320 is connected to the negative terminal of the power supply end of the electrical component, so that the electrical component can be powered. The wiring at the load end of the electrical component is organized through the hub assembly 210, which makes the circuit connection in the distribution cabinet clearer and more organized, and facilitates subsequent inspection and maintenance.

[0057] In summary, this application provides a first conductive structure 110 and a second conductive structure 120 in the first slide rail 100, and connects the first conductive structure 110 and the second conductive structure 120 to the positive and negative terminals of the power supply 510, respectively. They are also dynamically connected to the conductive structure in the slide rail through the terminals on the mounting bracket 300. When multiple electrical components are installed, the connection is made through the mounting bracket 300, which can effectively reduce the number of connection lines in the distribution cabinet. Furthermore, the dual slide rail design, with the first slide rail 100 carrying the conductive structure and equipped with an insulating isolation part 101, and the second slide rail 200 dedicated to the sliding of the hub assembly 210, achieves physical separation of power supply and load lines, making cable management more convenient and the wiring connections in the distribution cabinet neater and clearer, which is helpful for subsequent inspection and maintenance.

[0058] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
