Description

Technical Field

[0001] This utility model relates to the field of copper-aluminum composite busbar technology, and in particular to a copper-aluminum composite busbar with a high-voltage connector. Background Technology

[0002] Copper-aluminum composite busbars, also known as copper-clad aluminum busbars, copper-clad aluminum busbars, copper-clad aluminum busbars, or copper-aluminum composite busbars, are a high-tech, energy-saving conductor material. They combine the advantages of both copper and aluminum, using aluminum as the base material and a copper cladding layer. A special process creates a permanent interatomic metallurgical bond between the two metals. To prevent electrochemical corrosion, improve connection stability and conductivity, enhance weldability and aesthetics, copper-aluminum composite busbars are tin-plated when connected to other metal components in circuit connections.

[0003] When using copper-aluminum composite busbars in power systems, most installations involve bolts passing through holes in the busbars to connect them to electrical components. This method is not only slow and cumbersome, but also causes friction between the bolts and the busbars during bolt tightening. This friction damages the tin layer on the surface of the busbars, leaving them unprotected during subsequent use and affecting their lifespan.

[0004] To address this, a copper-aluminum composite busbar with a high-voltage connector is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a copper-aluminum composite busbar with a high-voltage connector to solve the problem mentioned in the background art, which mostly uses bolts through holes in the copper-aluminum composite busbar to install electrical components. This connection method is not only slow and cumbersome to operate, but also causes friction between the bolt and the copper-aluminum composite busbar during the tightening process. This friction damages the tin layer on the surface of the copper-aluminum composite busbar, thus preventing the copper-aluminum composite busbar from being protected by the tin layer during subsequent use, thereby affecting its service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a copper-aluminum composite busbar with a high-voltage connector, comprising a copper-aluminum composite busbar body, a high-voltage connector disposed on the copper-aluminum composite busbar body, and a terminal plate fixedly installed in the high-voltage connector. A rubber frame is fixedly connected to the copper-aluminum composite busbar body. A connecting assembly for quick installation and disassembly of the copper-aluminum composite busbar body is provided between the rubber frame and the high-voltage connector. The connecting assembly includes a push block disposed in the copper-aluminum composite busbar body, and a stop block is provided in the terminal plate. One end of the stop block is fixedly connected to a round locking post. It also includes a limiting assembly disposed on the high-voltage connector for enhancing the connection stability of the copper-aluminum composite busbar body. The limiting assembly includes an upper clamping plate and a lower clamping plate disposed on the high-voltage connector, and torsion springs are provided between the upper clamping plate and the high-voltage connector.

[0007] Preferably, a tension spring is fixedly connected between the push block and the rubber frame, and a protective pad is fixedly connected in the copper-aluminum composite strip body, with the protective pad being slidably connected to the push block.

[0008] Preferably, both the push block and the stop block have inclined surfaces at the same angle, and the circular locking post is slidably connected to the terminal plate.

[0009] Preferably, a spring is fixedly connected between the stop block and the terminal plate, and the spring is located on the outside of the circular locking post.

[0010] Preferably, the copper-aluminum composite strip body has a groove, and a rubber ring adapted to the round locking post is fixedly connected in the groove.

[0011] Preferably, a connecting plate is fixedly connected to the high-voltage connector, and the upper clamping plate and the lower clamping plate are rotatably connected to the connecting plate.

[0012] Preferably, a long rod is fixedly connected to the connecting plate, and a torsion spring is fixedly installed on the long rod.

[0013] Preferably, an extrusion plate is fixedly connected to the upper clamping plate, a notch is provided on the lower clamping plate for the extrusion plate to move, and a protrusion layer is provided on the copper-aluminum composite strip body.

[0014] The beneficial effects of this utility model are:

[0015] This invention enables the copper-aluminum composite busbar with a high-voltage connector to be quickly and conveniently connected to the circuit. By combining the connecting and limiting components, pressing the upper and lower clamping plates causes the torsion springs to rotate. After inserting the copper-aluminum composite busbar into the high-voltage connector, releasing the upper and lower clamping plates allows the torsion springs to push the push block, which in turn applies pressure to the stop block. This push block then pushes the round locking post into the groove, allowing the copper-aluminum composite busbar to quickly connect to the high-voltage connector. Simultaneously, the upper and lower clamping plates, in contact with the raised layer, limit and restrict the copper-aluminum composite busbar, preventing it from easily detaching. Pressing the upper and lower clamping plates again resets the push block under the action of the tension spring, causing the stop block to reset under the spring's reaction force, allowing the copper-aluminum composite busbar to be quickly removed from the high-voltage connector.

[0016] The entire device eliminates the need for traditional bolts when connecting the copper-aluminum composite busbar to the high-voltage connector, thus avoiding damage to the tin layer on the surface of the copper-aluminum composite busbar caused by bolt tightening. Furthermore, it allows for quick and easy installation and disassembly, improving the subsequent service life of the copper-aluminum composite busbar. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0027] like Figures 1 to 6As shown in the figure, a specific embodiment of this utility model provides a copper-aluminum composite busbar with a high-voltage connector, including a copper-aluminum composite busbar body 1, a high-voltage connector 2 disposed on the copper-aluminum composite busbar body 1, and a terminal plate 3 fixedly installed in the high-voltage connector 2. By setting the high-voltage connector 2, the copper-aluminum composite busbar body 1 can be easily and conveniently operated when connected to the circuit, and can be quickly installed and disassembled. A rubber frame 4 is fixedly connected to the copper-aluminum composite busbar body 1; a connecting component for quick installation and disassembly of the copper-aluminum composite busbar body 1 is provided between the rubber frame 4 and the high-voltage connector 2. By setting the connecting component, the copper-aluminum composite busbar body 1 can be quickly installed or disassembled in the high-voltage connector 2, replacing the traditional method of installing the copper-aluminum composite busbar body 1 with bolts, which is simple and quick, and also allows for… To prevent damage to the tin layer on the copper-aluminum composite busbar body 1, the connecting assembly includes a push block 5 in the copper-aluminum composite busbar body 1, a stop block 6 in the terminal plate 3, and a round locking post 7 fixedly connected to one end of the stop block 6; it also includes a limiting assembly on the high-voltage connector 2 to enhance the connection stability of the copper-aluminum composite busbar body 1. By setting the limiting assembly, the connection stability between the copper-aluminum composite busbar body 1 and the high-voltage connector 2 can be enhanced, making it difficult for the copper-aluminum composite busbar body 1 to come out of the high-voltage connector 2. At the same time, the setting of the limiting assembly assists in the installation and removal of the copper-aluminum composite busbar body 1 from the high-voltage connector 2. The limiting assembly includes an upper clamping plate 8 and a lower clamping plate 9 on the high-voltage connector 2, and torsion springs 10 are provided between the upper clamping plate 8 and the lower clamping plate 9 and the high-voltage connector 2.

[0028] like Figures 1 to 6As shown, a connecting plate 16 is fixedly connected to the high-voltage connector 2, and an upper clamping plate 8 and a lower clamping plate 9 are rotatably connected to the connecting plate 16. A long rod 17 is fixedly connected to the connecting plate 16, and a torsion spring 10 is fixedly installed on the long rod 17. When installing the copper-aluminum composite busbar body 1, the upper clamping plate 8 and the lower clamping plate 9 are pressed down to make them rotate between the connecting plate 16. At this time, after the upper clamping plate 8 and the lower clamping plate 9 rotate, the torsion spring 10 generates a reaction force after being pressured by the upper clamping plate 8 and the lower clamping plate 9. Then, the copper-aluminum composite busbar body 1 is inserted into the high-voltage connector 2. A pressing plate 18 is fixedly connected to the upper clamping plate 8, and a notch 19 for the pressing plate 18 to move is opened on the lower clamping plate 9. After the copper-aluminum composite busbar body 1 is inserted into the high-voltage connector 2, the pressure applied to the upper clamping plate 8 and the lower clamping plate 9 is released. At this time, under the reaction force of the torsion spring 10, the upper clamping plate 8 and the lower clamping plate 9 rotate and reset. A tension spring 11 is fixedly connected between the push block 5 and the rubber frame 4. A protective pad 12 is fixedly connected in the copper-aluminum composite busbar body 1, and the protective pad 12 is slidably connected to the push block 5. A groove 14 is provided in the copper-aluminum composite busbar body 1, and a rubber ring 15 adapted to the round locking post 7 is fixedly connected in the groove 14. During the reset process, the upper clamping plate 8 drives the pressing plate 18 to rotate during rotation. The rotating pressing plate 18 pushes the push block 5 to move. The moving push block 5 causes the tension spring 11 to rotate and the pressure spring 12 ... The force spring 11 stretches under pressure, generating a reaction force. As the push block 5 moves, it gradually approaches the stop block 6 and applies pressure to it. Since both the push block 5 and the stop block 6 have inclined surfaces at the same angle, the stop block 6, under the action of the push block 5, pushes the round locking post 7 into the groove 14. The rubber ring 15 reduces wear on the inner cavity of the groove 14 when the round locking post 7 enters it, thus reducing wear on the copper-aluminum composite strip body 1. A spring 13 is fixedly connected between the stop block 6 and the terminal plate 3, and the spring 13 is located outside the round locking post 7. The movement of the stop block 6 causes the spring 13 to contract under pressure, generating a reaction force. After the round locking post 7 enters the groove 14, it... The copper-aluminum composite busbar body 1 is connected to the high-voltage connector 2. The rotating upper clamping plate 8 and lower clamping plate 9 press the push block 5 to keep it stable. The copper-aluminum composite busbar body 1 is provided with a protruding layer 20, and the upper clamping plate 8 and lower clamping plate 9 are in close contact with the protruding layer 20, thereby blocking the copper-aluminum composite busbar body 1 and further enhancing its stability in the high-voltage connector 2. After the connection between the copper-aluminum composite busbar body 1 and the high-voltage connector 2 is completed, the high-voltage connector 2 can be directly inserted into its corresponding circuit plug, so that the copper-aluminum composite busbar body 1 can be connected to the circuit for use. In the whole device, the elastic force generated by the selected torsion spring 10 is greater than the elastic force generated by the tension spring 11.

[0029] like Figures 1 to 6As shown, specifically, when the copper-aluminum composite busbar body 1 needs to be removed for replacement or maintenance, the high-voltage connector 2 is removed from the plug, that is, the copper-aluminum composite busbar body 1 and the high-voltage connector 2 are removed from the circuit. Press down the upper clamping plate 8 and the lower clamping plate 9, so that they rotate again between the connecting plates 16. The torsion spring 10 generates a reaction force. At this time, the rotating upper clamping plate 8 and the lower clamping plate 9 disengage from the protrusion layer 20, and the pressing plate 18 on the upper clamping plate 8 disengages from the push block 5. The push block 5 is no longer subjected to force. At this time, the push block 5 moves back to its original position under the reaction force of the tension spring 11. The reset push block 5 disengages from the stop block 6, so the stop block 6 moves back to its original position under the reaction force of the spring 13. The moved and reset stop block 6 causes the round locking post 7 to move out of the groove 14. At this time, the copper-aluminum composite busbar body 1 can be taken out from the high-voltage connector 2, so that both can be replaced and maintained.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
