Description

Technical Field

[0001] This invention relates to the field of electrical cabinets, and more particularly to a multi-busbar mounting clamp. Background Technology

[0002] Electrical cabinets generally include distribution cabinets, power supply cabinets, speed control cabinets, auxiliary cabinets, and other related cabinets. To ensure unified management of incoming and outgoing lines, electrical cabinets are equipped with busbar systems. Generally, electrical cabinets adopt a three-phase four-wire system to meet power demand, plus a grounding busbar.

[0003] Busbars are copper or aluminum busbars that connect the main switch and the switches in each branch circuit of a power supply system. Their surfaces are insulated, and their main function is to act as conductors. All branches of the power distribution unit are connected to busbars; therefore, the installation quality of the busbars affects the performance of the power distribution unit. Based on their placement, busbars can be divided into horizontal busbars and vertical busbars. Traditionally, the assembly of horizontal busbars is done entirely inside the switch cabinet. Multiple busbars are placed one by one in their corresponding positions on the back of the cabinet and then tightened with screws. This vertical installation method is inconvenient, typically requiring at least two assemblers. This is not only labor-intensive and time-consuming with low efficiency, but also often causes busbar deformation and dimensional deviations due to limited space within the cabinet, affecting assembly quality, increasing rework rates, and increasing the workload of workers.

[0004] Therefore, it is necessary to provide a new multi-busbar mounting fixture to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a multi-busbar mounting fixture.

[0006] The multi-busbar mounting fixture provided by the present invention includes a base plate, a mounting frame, and multiple busbar mounting beams. The mounting frame is rotatably mounted on one side of the base plate. The multiple busbar mounting beams are respectively fixedly mounted on the mounting frame by multiple connectors. The multiple busbar mounting beams are perpendicular to the busbar mounting direction, and a fixture seat is inserted through the bottom of the multiple busbar mounting beams. Each of the multiple busbar mounting beams is provided with a locking assembly for fixing the fixture seat. Multiple insulating clamps are slidably mounted on the bottom of the fixture seat. An adjustment mechanism is provided on one side of the fixture seat to allow the multiple insulating clamps to move closer or further apart from each other.

[0007] Furthermore, the mounting frame includes a mounting frame and an adjusting frame. The back of the mounting frame is provided with a sliding groove. The adjusting frame is slidably installed in the sliding groove on the back of the mounting frame, and one end of the adjusting frame is rotatably connected to one side of the base plate. The adjusting frame is also provided with a fixing screw, and the bottom end of the fixing screw is in contact with the sliding groove. Multiple busbar mounting beams are fixedly connected to the mounting frame.

[0008] Furthermore, positioning holes are provided on one side of the top of both the clamp seat and the busbar mounting beam, and a positioning through groove is provided on the bottom of the busbar mounting beam. The engaging assembly is located between the positioning holes provided in the clamp seat and the busbar mounting beam.

[0009] Furthermore, the engaging assembly includes a positioning rod, a fixing plate, a telescopic column, and a U-shaped bracket. One end of the positioning rod passes through the positioning holes opened in the clamp seat and the busbar mounting beam, and two opposing positioning grooves are opened at one end of the positioning rod. The fixing plate is fixedly installed on one side of the busbar mounting beam. Both ends of the telescopic column are fixedly connected to the fixing plate and the U-shaped bracket, respectively. The other end of the U-shaped bracket engages with the two positioning grooves on the positioning rod.

[0010] Furthermore, the connector includes an upper screw and a lower screw. One end of the upper screw is threadedly connected to the busbar mounting beam and the mounting bracket. A threaded groove is provided at the bottom of the upper screw. The lower screw is located on the back of the mounting bracket, and the top of the lower screw is threadedly connected to the threaded groove of the upper screw.

[0011] Furthermore, the adjustment mechanism includes an adjustment rod, which is rotatably mounted on one side of the busbar mounting beam. The outer surface of the adjustment rod is divided into multiple adjustment areas, and each of the multiple adjustment areas has two oppositely arranged threaded segments. The multiple insulating clamps are respectively threaded to the threaded segments in the multiple adjustment areas.

[0012] Furthermore, the telescopic column includes a fixed column and a movable column. One end of the fixed column is fixedly installed on one side of the fixed plate, and one end of the movable column is slidably installed inside the fixed column. The other end of the movable column is fixedly connected to the U-shaped bracket. A reset spring is provided inside the fixed column, and the two ends of the reset spring are fixedly connected to the inner side wall of the fixed column and one end of the movable column, respectively.

[0013] Furthermore, an inner polygonal adjustment groove is provided on one side of the adjustment rod, and an adjustment hole corresponding to the position of the inner polygonal adjustment groove is provided on the mounting frame.

[0014] Compared with related technologies, the multi-busbar mounting fixture provided by the present invention has the following advantages:

[0015] 1. This invention allows multiple busbars to be temporarily connected and installed by placing them flat on the corresponding positions on the mounting frame. Then, the mounting frame is rotated 90 degrees to install the multiple busbars on the back of the cabinet. After the installation is complete, the clamps can be removed, thus improving the installation efficiency of the busbars.

[0016] 2. This invention uses a modular design to allow for quick disassembly and replacement of the busbar mounting beam and clamp seat via snap-fit ​​components and connectors, shortening installation time. When the adjusting rod is rotated, the insulating clamps on the left and right sides move towards the center or outwards respectively, achieving clamping or releasing of the busbar. Through the multi-area threaded section of the adjusting rod, multiple insulating clamps can be adjusted synchronously, ensuring the parallelism and consistency of the busbar installation. Multiple busbars can be installed and disassembled simultaneously. Attached Figure Description

[0030] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. In addition, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0032] In the specific implementation process, such as Figures 1-9 As shown, the multi-busbar mounting fixture includes a base plate 1, a mounting frame, and multiple busbar mounting beams 2. The mounting frame is rotatably mounted on one side of the base plate 1. The multiple busbar mounting beams 2 are fixedly mounted on the mounting frame by multiple connectors. The multiple busbar mounting beams 2 are perpendicular to the busbar installation direction, and a fixture seat 3 is inserted through the bottom of the multiple busbar mounting beams 2. Each of the multiple busbar mounting beams 2 is provided with a locking assembly for fixing the fixture seat 3. Multiple insulating clamps 4 are slidably mounted on the bottom of the fixture seat 3. One side of the fixture seat 3 is provided for the multiple insulating clamps 4 to move closer or further apart from each other. The adjusting rod 18 is rotatably mounted on one side of the busbar mounting beam 2. The outer surface of the adjusting rod 18 is divided into multiple adjusting areas. Each adjusting area has two oppositely arranged threaded sections 19. Multiple insulating clamps 4 are threadedly connected to the threaded sections 19 in the multiple adjusting areas. When the adjusting rod 18 is rotated, the left and right insulating clamps 4 move towards the center or outwards respectively, thereby clamping or releasing the busbar. Through the multi-area threaded sections 19 of the adjusting rod 18, the multiple insulating clamps 4 are adjusted synchronously to ensure the parallelism and consistency of the busbar installation.

[0033] It is worth noting that the insulating clamp 4 prevents the busbar from coming into direct contact with metal parts, thus reducing the risk of short circuits.

[0034] It should be noted that the reference Figure 2 As shown, the mounting frame includes a mounting frame 5 and an adjusting frame 6. The back of the mounting frame 5 is provided with a sliding groove 7. The adjusting frame 6 is slidably installed in the sliding groove 7 on the back of the mounting frame 5, and one end of the adjusting frame 6 is rotatably connected to one side of the base plate 1. The adjusting frame 6 is also provided with a fixing screw 8, and the bottom end of the fixing screw 8 is in contact with the sliding groove 7. Multiple busbar mounting beams 2 are fixedly connected to the mounting frame 5.

[0035] It should be noted that the reference Figure 9As shown, the connector includes an upper screw 15 and a lower screw 16. One end of the upper screw 15 is threadedly connected to the busbar mounting beam 2 and the mounting bracket. The bottom of the upper screw 15 has a threaded groove 17. The lower screw 16 is located on the back of the mounting bracket, and the top of the lower screw 16 is threadedly connected to the threaded groove 17 of the upper screw 15. The busbar mounting beam 2 is fixed to the mounting bracket by the upper screw 15, and the lower screw 16 is locked by the threaded groove 17 to ensure that the mounting beam will not be displaced during installation. At the same time, the double threads ensure the stability of the connection.

[0036] Optional, see reference Figure 7 As shown, positioning holes 9 are provided on the top side of both the clamp base 3 and the busbar mounting beam 2, and positioning through grooves 10 are provided on the bottom of the busbar mounting beam 2. The engaging assembly is located between the positioning holes 9 provided on the clamp base 3 and the busbar mounting beam 2.

[0037] It should be noted that the reference Figure 5 as well as Figure 6 The engaging assembly includes a positioning rod 11, a fixing plate 12, a telescopic column, and a U-shaped locking seat 13. One end of the positioning rod 11 passes through the positioning holes 9 opened in the clamp seat 3 and the busbar mounting beam 2, and two opposing positioning grooves 14 are opened at one end of the positioning rod 11. The fixing plate 12 is fixedly installed on one side of the busbar mounting beam 2. Both ends of the telescopic column are fixedly connected to the fixing plate 12 and the U-shaped locking seat 13, respectively. The other end of the U-shaped locking seat 13 engages with the two positioning grooves 14 on the positioning rod 11. The U-shaped locking seat 13 is connected to the fixing plate 12 through the telescopic column. The return spring inside the telescopic column provides a rebound force, so that the U-shaped locking seat 13 is always engaged in the positioning grooves 14. When the U-shaped locking seat 13 is disengaged from the positioning grooves 14, the spring inside the telescopic column is compressed, and the positioning rod 11 can be pulled out from the positioning holes 9 opened in the clamp seat 3 and the busbar mounting beam 2, thus separating the clamp seat 3 and the busbar mounting beam 2.

[0038] To further clarify, refer to Figure 6 As shown, the telescopic column includes a fixed column 20 and a movable column 21. One end of the fixed column 20 is fixedly installed on one side of the fixed plate 12, and one end of the movable column 21 is slidably installed inside the fixed column 20. The other end of the movable column 21 is fixedly connected to the U-shaped bracket 13. A reset spring is provided inside the fixed column 20. The two ends of the reset spring are fixedly connected to the inner side wall of the fixed column 20 and one end of the movable column 21, respectively. By pulling the U-shaped bracket 13, the movable column 21 is moved. The reset spring is used to drive the movable column 21 to reset and automatically drive the U-shaped bracket 13 to be fixed.

[0039] Example 2

[0040] In a specific implementation process, refer to Figure 3 as well as Figure 4As shown, an inner polygonal adjustment groove 22 is provided on one side of the adjustment rod 18, and an adjustment hole 23 corresponding to the position of the inner polygonal adjustment groove 22 is provided on the mounting frame 5. Preferably, the inner polygonal adjustment groove 22 is a regular hexagon. A special tool (such as a hex wrench) can be inserted into the adjustment groove and the adjustment rod 18 can be rotated to adjust the opening and closing distance of the insulating clamp 4 to adapt to busbars of different thicknesses.

[0041] The working principle provided by this invention is as follows: When using this fixture, the angle between the mounting frame and the base plate 1 is adjusted by rotating the adjustment frame 6, so that the busbar mounting beam 2 is perpendicular to the busbar installation direction, ensuring the parallel arrangement of the busbars. Multiple busbars are temporarily connected and installed by placing them flat on the corresponding positions on the mounting frame. Then, the mounting frame is flipped 90 degrees to install multiple busbars on the back of the cabinet. The two ends of the telescopic column are fixedly connected to the fixing plate 12 and the U-shaped bracket 13, respectively. The other end of the U-shaped bracket 13 engages with the two positioning grooves 14 on the positioning rod 11. The U-shaped bracket 13 is connected to the fixing plate 12 through the telescopic column. The return spring inside the telescopic column provides a rebound force, so that the U-shaped bracket... The seat 13 is always engaged in the positioning groove 14. When the U-shaped seat 13 is disengaged from the positioning groove 14, the compression spring in the telescopic column is compressed, and the positioning rod 11 can be pulled out from the positioning hole 9 opened in the clamp seat 3 and the busbar mounting beam 2. The clamp seat 3 and the busbar mounting beam 2 can be separated. A special tool can be inserted into the adjustment groove and the adjustment rod 18 can be rotated to adjust the opening and closing distance of the insulating clamp 4. When the adjustment rod 18 is rotated, the left and right insulating clamps 4 move towards the center or outward respectively to achieve clamping or releasing of the busbar. Through the multi-area threaded section 19 of the adjustment rod 18, multiple insulating clamps 4 can be adjusted synchronously to ensure the parallelism and consistency of the busbar installation and to adapt to busbars of different thicknesses.
