Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, and in particular to a copper-aluminum composite conductive busbar that is resistant to electrochemical corrosion. Background Technology

[0002] Copper-aluminum composite busbars are a new type of conductive material that combines copper and aluminum through special processes (such as explosive welding and rolling). They combine the high conductivity and good oxidation resistance of copper with the lightweight and low cost advantages of aluminum. They are key components used to transmit current in electrical systems. The electrochemical corrosion resistant copper-aluminum composite busbar is an improved conductive component based on conventional copper-aluminum composite busbars, which solves the problem of electrochemical corrosion caused by the difference in electrochemical properties when copper and aluminum come into contact through specific technical means.

[0003] A search revealed Chinese Patent Publication No. CN218788477U, which discloses a copper-aluminum composite conductive busbar structure. The structure includes a conductive busbar body, integrally formed, comprising a copper conductive busbar and an aluminum conductive busbar. The copper conductive busbar includes a first horizontal portion, a vertical portion, and a second horizontal portion. One side of the first horizontal portion is connected to the aluminum conductive busbar. The vertical portion extends upwards from the other side of the first horizontal portion, and the second horizontal portion extends outwards from the upper end of the vertical portion. The copper-aluminum composite conductive busbar structure is quick and efficient to manufacture, ensuring product strength and preventing the conductive busbar from detaching, leading to poor contact or even short circuits. It also improves production efficiency and enhances the user experience. However, the copper-aluminum composite conductive busbar structure relies on bolt connections during use. During operation, the conductive busbar generates heat due to current flow, causing thermal expansion and contraction of the copper and aluminum materials. Long-term, repeated temperature changes can create gaps between the bolts and the connecting holes. Simultaneously, vibrations during equipment operation and external mechanical impacts gradually weaken the bolt's preload, eventually leading to loosening. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a copper-aluminum composite conductive busbar that is resistant to electrochemical corrosion. It aims to improve the existing copper-aluminum composite conductive busbars that rely on bolt connections. During operation, the current generates heat, causing the copper and aluminum to expand and contract. Long-term temperature differences lead to gaps between the bolts and the connecting holes. Equipment vibration and mechanical impact can also weaken the bolt preload, eventually causing loosening.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a copper-aluminum composite conductive busbar resistant to electrochemical corrosion, comprising a conductive busbar body, wherein multiple elongated inner sliding groove plates are fixedly connected at equal intervals on the right side of the outer wall of the conductive busbar body, a sliding plate is slidably connected to an adjacent side of the inner wall of each elongated inner sliding groove plate, a C-shaped plate is fixedly connected to an adjacent side of the outer wall of each sliding plate, a C-shaped spring ring is fixedly connected to an adjacent side of the outer wall of each C-shaped plate, an extension belt is installed on an adjacent side of the outer wall of each C-shaped plate, a lead screw is rotatably connected to the inner wall of each elongated inner sliding groove plate, and a worm gear is fixedly connected to the top of each lead screw.

[0006] As a further description of the above technical solution:

[0007] The top of each of the elongated inner sliding plates is fixedly connected to a hollow block, and a worm gear is rotatably connected inside the hollow block.

[0008] As a further description of the above technical solution:

[0009] The worm gear is engaged with the worm.

[0010] As a further description of the above technical solution:

[0011] The inside of the slide plate is threadedly connected to the outer wall of the lead screw.

[0012] As a further description of the above technical solution:

[0013] The conductive outlet has a bolt threaded connection on the right side of its inner wall.

[0014] As a further description of the above technical solution:

[0015] A small mounting groove is provided on the top left side of the conductive busbar.

[0016] As a further description of the above technical solution:

[0017] A large mounting groove is provided on the top right side of the conductive busbar.

[0018] As a further description of the above technical solution:

[0019] Both the small mounting slot and the large mounting slot are circular in shape.

[0020] This utility model has the following beneficial effects:

[0021] In this invention, rotating the worm gear drives the worm wheels on both sides and the reverse threaded screw to rotate, causing the slide plate connected to it to move relative to the elongated inner slide plate, which in turn drives the C-shaped plate and C-shaped spring ring to move closer or further away. The elasticity and clamping force are used to firmly clamp the bolt, and the extension belt enhances the adaptability. The bolt is tightly fixed and prevented from loosening through the movement of the reverse screw. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides: a copper-aluminum composite conductive busbar resistant to electrochemical corrosion, comprising a conductive busbar body 1, a plurality of elongated inner sliding groove plates 4 are fixedly connected at equal intervals on the right side of the outer wall of the conductive busbar body 1, a sliding plate 6 is slidably connected to the adjacent side of the inner wall of the elongated inner sliding groove plates 4, a C-shaped plate 8 is fixedly connected to the adjacent side of the outer wall of the sliding plate 6, a C-shaped spring ring 10 is fixedly connected to the adjacent side of the outer wall of the C-shaped plate 8, an extension belt 5 is installed on the adjacent side of the outer wall of the C-shaped plate 8, a lead screw 11 is rotatably connected to the inner wall of the elongated inner sliding groove plates 4, a worm wheel 9 is fixedly connected to the top of the lead screw 11, a hollow block 3 is fixedly connected to the top of the elongated inner sliding groove plates 4, a worm 7 is rotatably connected inside the hollow block 3, and the worm wheel 9 is meshed with the worm 7;

[0030] Specifically, when the worm 7 is rotated, it drives the worm wheels 9 on both sides and the lead screw 11 to rotate synchronously. Since the slide plate 6 is threadedly connected to the lead screw 11 and slides in the elongated inner slide plate 4, the lead screw 11 with opposite threads will drive the slide plates 6 on both sides to move closer or further apart. The slide plate 6 drives the C-shaped plate 8 and the C-shaped spring ring 10 to move. The elasticity of the C-shaped spring ring 10 combined with the clamping force of the C-shaped plate 8 forms a stable clamp on the bolt 2 that is inserted into the conductive busbar 1. The extension belt 5 can enhance the clamping adaptability. Finally, the bolt 2 is tightly fixed by the relative movement of the reverse threaded lead screw 11 to prevent loosening.

[0031] Reference Figure 3 and Figure 4 The inside of the slide plate 6 is threaded to the outer wall of the lead screw 11, and the right side of the inner wall of the conductive bus 1 is threaded with a bolt 2. A small mounting groove 12 is opened on the top left side of the conductive bus 1.

[0032] Specifically, the bolts 2 on the right side of the inner wall of the conductive busbar 1 serve to fix or connect. By tightening the bolts 2, the conductive busbar 1 can be firmly connected to other mating parts. The small mounting groove 12 opened on the top left side of the conductive busbar 1 can be used to install small accessories or to form a positioning fit with other parts to ensure the coordination of the overall structure and the accuracy of the operation.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The top right side of the conductive busbar 1 is provided with a large mounting groove 13, and both the small mounting groove 12 and the large mounting groove 13 are circular in shape.

[0034] Specifically, the left side of the small mounting slot 12 and the right side of the large mounting slot 13 can accommodate components of different specifications due to their size differences: the small mounting slot 12 is suitable for installing small circular accessories such as small positioning parts and signal interfaces, while the large mounting slot 13 can accommodate larger circular components such as main connectors and current transmission terminals, thus realizing the functional partitioning of the conductor busbar 1 and avoiding spatial interference between different components.

[0035] Working principle: When the worm 7 is rotated, it drives the worm wheels 9 on both sides and the lead screw 11 to rotate synchronously. Since the slide plate 6 is threadedly connected to the lead screw 11 and slides in the elongated inner slide plate 4, the lead screw 11 with opposite threads will drive the slide plates 6 on both sides to move closer or further apart. The slide plate 6 drives the C-shaped plate 8 and the C-shaped spring ring 10 to move. The elasticity of the C-shaped spring ring 10 combined with the clamping force of the C-shaped plate 8 forms a stable clamp on the bolt 2 that is inserted into the conductive busbar 1. The extension belt 5 can enhance the clamping adaptability. Finally, the bolt 2 is tightly fixed by the relative movement of the reverse threaded lead screw 11 to prevent loosening.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
