Description

Technical Field

[0001] This utility model relates to the field of copper busbar installation technology, and in particular to a copper busbar clamping device for switchgear. Background Technology

[0002] Copper busbars, also known as copper busbars, are long conductors made of copper with a rectangular or chamfered rectangular cross-section. They are mainly used for transmitting current and connecting electrical equipment. Based on hardness, they are divided into hard copper busbars and soft copper busbars. The manufacturing process includes raw material preparation, drawing and forming, surface treatment, and cutting. Selection should be based on a comprehensive consideration of factors such as current, installation environment, and surface treatment.

[0003] Chinese Patent CN210608026U discloses a copper busbar clamping device for switchgear, belonging to the field of copper busbar installation technology. It includes a cabinet and several clamping components installed on the side wall of the cabinet. Each clamping component includes a drive rod, several clamping plates, and a threaded rod. A sliding channel is provided on the side wall of the cabinet. One end of the drive rod extends from inside the cabinet into the sliding channel, and an inner cavity is provided inside the drive rod. The threaded rod extends from outside the cabinet into the sliding channel and is threaded into the inner cavity. The clamping plates are correspondingly slidably installed on the upper and lower sides of the drive rod. When clamping the copper busbar, the threaded rod drives the drive rod to move into the sliding channel, and the inner wall of the cabinet restricts the clamping plates. This allows for the clamping of multiple copper busbars, offering advantages such as simple structure, good clamping effect, and convenient installation and removal. Furthermore, it reduces the space occupied inside the cabinet during copper busbar clamping, making it highly practical.

[0004] The copper busbars inside the electrical switch cabinet cannot be of uniform length depending on the usage requirements. In actual use, the device can only clamp copper busbars of the same length. If the copper busbars are of different lengths, they need to be trimmed to a suitable length later. This not only increases the operation process and reduces work efficiency, but may also introduce errors during the trimming process, affecting the installation accuracy and electrical performance of the copper busbars in the electrical switch cabinet. Utility Model Content

[0005] The main purpose of this utility model is to provide a copper busbar clamping device for switch cabinets, which can effectively solve the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A copper busbar clamping device for a switch cabinet includes a cabinet body with open front and rear ends. Two limiting frames are fixedly installed on the front and rear sides of the cabinet body. Two inspection doors are opened and closed at the two open ends of the cabinet body. The end faces of the two inspection doors are respectively attached to the two limiting frames. A spacing adjustment component is vertically slidably arranged in the inner cavity of the limiting frame. Multiple connecting insulating plates are respectively arranged on the spacing adjustment component, and clamping components are arranged on the multiple connecting insulating plates.

[0008] Preferably, the spacing adjustment component includes two toothed shafts, which are symmetrically installed at both ends of the inner cavity of the limiting frame in the height direction.

[0010] Preferably, the rear ends of the plurality of toothed plates are respectively engaged with the two toothed shafts, and the outer surfaces of the plurality of guide rods are respectively fitted with a plurality of springs, the two ends of the plurality of springs respectively abutting between the plurality of toothed plates and the front side of the inner cavity of the plurality of slide frames.

[0011] Preferably, the clamping assembly includes two sliding grooves, an insulating clamping frame, and two telescopic rods. The two sliding grooves are symmetrically opened through the front end of the connecting insulating plate on both sides away from the center. The two ends of the insulating clamping frame in the width direction slide on the inner surface of the two sliding grooves. The two telescopic rods are symmetrically fixedly installed on both sides of the back end of the connecting insulating plate away from the center.

[0012] Preferably, the back end of the insulating clamp frame has two symmetrical through holes on both sides away from the middle, which slide through the two telescopic rods.

[0013] Preferably, the front end of the insulating clamp frame has multiple threaded holes that are equidistantly through it, and multiple handle screws are threaded onto the inner surface of the multiple threaded holes respectively. Multiple insulating blocks are fixedly connected to the end face of the multiple handle screws near the slide groove respectively.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model uses a spacing adjustment component to adjust the spacing between multiple connecting insulating plates, so that the height of the connecting insulating plates can be precisely adjusted according to the actual length of the copper busbar. In this way, when installing copper busbars, it can ensure that copper busbars of different lengths can achieve effective and stable installation, avoiding the need to trim the copper busbars for adaptation, thereby enhancing the work efficiency and performance of copper busbar installation.

[0016] 2. This utility model uses a clamping component to clamp the copper busbar onto the connecting insulating plate for limiting its position, which enhances the stability of the copper busbar after installation and effectively prevents the copper busbar from loosening or detaching due to factors such as vibration and displacement. This ensures the reliability of the copper busbar connection during power transmission. At the same time, the clamping component can effectively clamp copper busbars of different thicknesses, making this device more versatile for copper busbars of different thicknesses.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1

[0025] Specific examples Figures 1-4As shown, a copper busbar clamping device for a switch cabinet includes a cabinet 1. The front and rear ends of the cabinet 1 are open. Two limiting frames 2 are fixedly installed on the front and rear sides of the inner cavity of the cabinet 1. Two inspection doors 3 are opened and closed at the two open ends of the cabinet 1. The end faces of the two inspection doors 3 that are close to each other are respectively attached to the two limiting frames 2. A spacing adjustment component 4 is vertically slidably arranged in the inner cavity of the limiting frame 2. Multiple connecting insulating plates 5 are respectively arranged on the spacing adjustment component 4. Clamping components 6 are arranged on the multiple connecting insulating plates 5.

[0026] In this embodiment, the spacing between multiple connecting insulating plates 5 is adjusted by setting the spacing adjustment component 4 during actual operation. This allows the connecting insulating plates 5 to be precisely adjusted in height according to the actual length of the copper busbar. This ensures that copper busbars of different lengths can be installed effectively and stably, avoiding the need to trim the copper busbars for adaptation. The clamping component 6 clamps the copper busbars onto the connecting insulating plate 5 for limiting their position, which enhances the stability of the copper busbars after installation and effectively prevents the copper busbars from loosening or detaching due to vibration, displacement, or other factors, thus ensuring the reliability of the copper busbar connection during power transmission.

[0027] In this design, two access doors 3 are installed on the front and rear openings of cabinet 1, which facilitates maintenance personnel to maintain and install the electrical components installed inside cabinet 1 from multiple angles.

[0028] Specifically, the spacing adjustment component 4 includes two toothed shafts 41, which are symmetrically installed at both ends of the inner cavity of the limiting frame 2 in the height direction. Multiple sliding frames 42 are symmetrically slidably installed between the two toothed shafts 41, and multiple connecting insulating plates 5 are fixedly installed between the opposite surfaces of the multiple symmetrical sliding frames 42.

[0029] Multiple guide holes 421 are respectively opened through the front end of multiple sliding frames 42, multiple guide rods 43 are slidably installed on the inner surface of multiple guide holes 421, and toothed plates 44 are respectively fixedly installed at the rear end of multiple guide rods 43.

[0030] The rear ends of multiple toothed plates 44 are respectively engaged with two toothed shafts 41, and multiple springs 45 are respectively sleeved on the outer surface of multiple guide rods 43. The first and last ends of multiple springs 45 are respectively abutted between the multiple toothed plates 44 and the front side of the inner cavity of multiple slide frames 42.

[0031] Pull the guide rod 43 forward to release the limiting effect between the toothed plate 44 and the toothed shaft 41. This allows the connecting insulating plate 5 to slide up and down along the toothed shaft 41, adjusting its position. Once the connecting insulating plate 5 is in the correct position, release the guide rod 43. The tension of the spring 45 will push the toothed plate 44 back to maintain the limiting effect between it and the toothed shaft 41, preventing unnecessary displacement of the connecting insulating plate 5.

[0032] The copper busbar is clamped onto the connecting insulating plate 5 by the clamping assembly 6 provided on the connecting insulating plate 5 to prevent the copper busbar from becoming loose.

[0033] Example 2

[0034] Based on Embodiment 1, the copper busbar is clamped by setting clamping component 6.

[0035] Specific examples Figure 2 and 5 As shown, the clamping assembly 6 includes two sliding grooves 61, an insulating clamping frame 62, and two telescopic rods 63. The two sliding grooves 61 are symmetrically opened through the front end of the connecting insulating plate 5 on both sides away from the middle. The two ends of the insulating clamping frame 62 slide on the inner surface of the two sliding grooves 61 in the width direction. The two telescopic rods 63 are symmetrically fixedly installed on both sides of the back end of the connecting insulating plate 5 away from the middle.

[0036] The back end of the insulating frame 62 is symmetrically provided with two telescopic holes 621 that slide with the two telescopic rods 63 on both sides away from the middle. The outer surfaces of the two telescopic rods 63 are respectively fitted with two springs 64. The two ends of the two springs 64 are respectively abutted between the back end of the slide groove 61 and the opposite surface of the insulating frame 62.

[0037] The front end of the insulating clamp frame 62 has multiple threaded holes 65 that are equidistantly through it. Multiple handle screws 66 are threadedly installed on the inner surface of the multiple threaded holes 65. Multiple insulating blocks 661 are fixedly connected to the end face of the multiple handle screws 66 near the slide groove 61.

[0038] When clamping the copper busbar, first push the rear end of the insulating clamping frame 62 forward, insert the copper busbar between the front end of the connecting insulating plate 5 and the front side of the inner cavity of the insulating clamping frame 62. After releasing the push on the rear end of the insulating clamping frame 62, the insulating clamping frame 62 slides backward by the tension of the spring 64. In this way, the front end of the inner cavity of the insulating clamping frame 62 and the front surface of the connecting insulating plate 5 together clamp the copper busbar.

[0039] Because of the different thicknesses of the copper busbars, when multiple copper busbars of different thicknesses are clamped side by side during the implementation of this solution, the thinner copper busbars cannot be clamped by the connecting insulating plate 5 and the insulating clamp frame 62. At this time, turning the handle screw 66 will push the insulating abutment block 661 to hold the thinner copper busbar against the connecting insulating plate 5. Turning the handle screw 66 in the reverse direction will release the insulating abutment block 661 from the connecting insulating plate 5, and the copper busbar can be removed.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
