Description

Technical Field

[0001] This utility model relates to the field of copper busbar clamp technology, specifically a copper busbar clamp device. Background Technology

[0002] In the field of power system and electrical equipment assembly, copper busbars, as the core conductive components that carry current, are directly related to the safe and stable operation of the entire electrical system by the reliability of their connection and fixation. Copper busbar clamps, as key components specifically used for positioning and fastening copper busbars, are widely used in various electrical scenarios such as distribution cabinets, switch cabinets, and new energy equipment.

[0003] As electrical equipment evolves towards integration, miniaturization, and multi-dimensional layout, increasingly higher demands are placed on the structural adaptability, installation flexibility, and clamping stability of copper busbar clamping devices.

[0004] However, most of the mainstream copper busbar clamping devices on the market currently adopt an integrated fixing structure design. These devices have certain limitations in practical applications. On the one hand, the clamping size and installation angle of the integrated structure are relatively fixed, making it difficult to adapt to copper busbars with various distribution patterns such as vertical, horizontal, and diagonal in different installation scenarios, and they cannot well adapt to copper busbars with different spacing. On the other hand, when fixing an array composed of multiple copper busbars, it is easy to cause insufficient overall stability of the copper busbar array, which may loosen during long-term use, thereby affecting the reliability of electrical connections. The adaptability and practicality need to be improved. In view of this, we propose a copper busbar clamping device. Utility Model Content

[0005] The purpose of this invention is to provide a copper busbar clamping device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A copper busbar clamping device includes a switch component. A first copper busbar is fixedly connected to one end of the switch component. A second copper busbar is fixedly connected to one end of the first copper busbar away from the switch component. The second copper busbar is connected to other copper busbars or electrical components at one end away from the first copper busbar. A clamping plate is provided on the outside of the switch component. A through slot is formed on the clamping plate. A first screw and a second screw are respectively fitted inside the two ends of the through slot. A short plate is fixedly installed on one end of the first screw. A first nut is threadedly fitted on the end of the first screw away from the short plate. A long plate is fixedly installed on one end of the second screw. A second nut is threadedly fitted on the end of the second screw away from the long plate. An insulating block is fixedly installed on the clamping plate. The insulating block is attached to the outside of the first copper busbar or the second copper busbar.

[0007] In a further embodiment, multiple sets of the first and second copper busbars are provided.

[0008] In a further embodiment, two sets of clamps, through slots, and insulating blocks are provided on the outside of each of the first or second copper busbars.

[0009] In a further embodiment, the two sets of clamps, through slots, and insulating blocks are mirror-mounted at both ends of the first or second copper busbar.

[0010] In a further embodiment, multiple sets of the first screw, short plate, first nut, long plate, second screw, and second nut are provided, and the split design better adapts to copper busbars that are distributed vertically, horizontally, or diagonally.

[0011] In a further embodiment, two sets of second screws and second nuts are provided on the single set of long plates, and the two sets of second screws and second nuts are respectively located inside two sets of through slots that are adjacent to each other at the beginning and end, which improves the flexibility and adaptability of the device.

[0012] In a further embodiment, the short plate, the first nut, the long plate, and the second nut are all fitted to the outside of the clamping plate, which improves the overall stability of the first copper busbar and the second copper busbar array group.

[0013] Compared with the prior art, the present invention provides a copper busbar clamping device, which has the following beneficial effects: This copper busbar clamping device works by passing a first screw through a slot in two mirror-shaped clamping plates, causing the shorter plate to fit against the outside of the clamping plate. Then, two second screws on the longer plate pass through slots in adjacent clamping plates, causing the longer plate to fit against the outside of the corresponding clamping plate. This process is repeated until all the first and second screws are in place. After all the first and second screws are in place, the first nut is tightened on the first screw, and the second nut is tightened on the second screw. This ensures that all insulating blocks are stably attached to the outside of the first or second copper busbar. Compared with traditional integrated fixing clamping devices, the split design better adapts to copper busbar components that are vertically, horizontally, or diagonally distributed, improving the flexibility and adaptability of the device. It also better accommodates copper busbar components with different spacing, resulting in better overall stability of the first and second copper busbar arrays and improving practicality.

Further, the first copper busbar 2 and the second copper busbar 3 are provided in three sets.

[0019] In one embodiment of this utility model, a clamping plate 4 is provided on the outside of the switch component 1. A through groove 5 is provided on the clamping plate 4. A first screw 6 and a second screw 11 are respectively sleeved inside the two ends of the through groove 5. A short plate 7 is fixedly installed at one end of the first screw 6. A first nut 8 is threadedly engaged at the end of the first screw 6 away from the short plate 7. A long plate 10 is fixedly installed at one end of the second screw 11. A second nut 12 is threadedly engaged at the end of the second screw 11 away from the long plate 10. An insulating block 9 is fixedly installed on the clamping plate 4. The insulating block 9 is attached to the outside of the first copper busbar 2 or the second copper busbar 3.

[0020] In one embodiment of this utility model, two sets of clamping plates 4, through slots 5, and insulating blocks 9 are provided on the outside of a single first copper busbar 2 or second copper busbar 3. Further, the two sets of clamping plates 4, through slots 5, and insulating blocks 9 are mirror images of each other at both ends of the first copper busbar 2 or second copper busbar 3. Further, four sets of first screws 6, short plates 7, first nuts 8, long plates 10, second screws 11, and second nuts 12 are provided. The split design better adapts to copper busbar components that are distributed vertically, horizontally, or diagonally. Further, two sets of second screws 11 and second nuts 12 are provided on a single set of long plates 10, and the two sets of second screws 11 and second nuts 12 are respectively located inside two sets of through slots 5 that are adjacent to each other, which improves the flexibility and adaptability of the device. Further, the short plates 7, first nuts 8, long plates 10, and second nuts 12 are all attached to the outside of the clamping plates 4, which makes the overall stability of the array of first copper busbar 2 and second copper busbar 3 better.

[0021] Working principle: First, basic positioning is performed. For a single set of first copper busbar 2 or second copper busbar 3, two sets of clamping plates 4 are arranged in a mirror-symmetrical manner at their two ends. During this process, it is necessary to ensure that the pre-set insulating blocks 9 on the clamping plates 4 are completely attached to the outer surface of the first copper busbar 2 or second copper busbar 3. The insulating blocks 9 not only provide electrical insulation protection, but also provide an initial positioning reference for the clamping plates 4, avoiding direct contact between the clamping plates 4 and the copper busbar, which could cause wear or electrical conductivity hazards. Take the first screw 6 and pass it through the corresponding through slots 5 on the two sets of mirror-arranged clamping plates 4. Since a short plate 7 has been pre-fixed at one end of the first screw 6, After the first screw 6 is fully inserted into the through slot 5, the short plate 7 will naturally fit against the outside of one of the clamping plates 4, forming a preliminary limiting structure. Then, take the long plate 10, on which two sets of second screws 11 are pre-fixed. Align these two sets of second screws 11 with each other and insert them into the through slots 5 on the two adjacent clamping plates 4, ensuring that the long plate 10 fits tightly against the outside of the corresponding clamping plate 4. The function of the long plate 10 is to connect adjacent copper busbar clamping units, forming an integrated linkage structure and improving the overall integrity of the multi-group copper busbar array. According to the above, "positioning clamping plate 4—installing the first screw 6 and short plate 7—assembling the long plate 10 and short plate 7," the following steps are performed: The "two screws 11" step involves sequentially installing and positioning the four sets of components: the first screw 6, the short plate 7, the first nut 8, the long plate 10, the second screw 11, and the second nut 12. After all screw-like parts are in place, the tightening and locking stage begins. Using an adapter tool, the first nut 8 is tightened at the end of the first screw 6 furthest from the short plate 7, and the second nut 12 is tightened at the end of the second screw 11 furthest from the long plate 10. The axial pressure generated by the threaded engagement causes the short plate 7 and the first nut 8 to clamp the corresponding clamping plates 4 from both sides. The long plate 10 and the second nut 12 also clamp and fix the adjacent clamping plates 4 in the same way. Ultimately, with the synergistic effect of all components, all insulating blocks 9 can be stably attached to the outside of the first copper busbar 2 or the second copper busbar 3, completing the secure clamping of the copper busbar. Compared with the traditional integrated device, this split design can flexibly adjust the assembly position of each clamping plate 4, screw and plate to adapt to copper busbar components with different distribution patterns such as vertical, horizontal or diagonal, which significantly improves the device's scene adaptability and operational flexibility, better adapts to copper busbar components with different spacing, and also ensures that the array group composed of the first copper busbar 2 and the second copper busbar 3 has better structural stability, effectively ensuring the reliability of electrical connection.

The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
