[0002] The incoming power busbar is an electrical conductor made of copper and other metal materials. It is widely used in modern electrical engineering. It is commonly used in cable joints, distribution panels and electrical equipment. It can be used to connect high-voltage lines, low-voltage lines and control lines. Compared with traditional wires and cables, it has higher conductivity and better corrosion resistance.

[0003] In the prior art, such as the copper busbar installation structure of the circuit breaker incoming line cabinet proposed in patent application number "CN202021932470.9", a connecting panel and a connecting block are provided on the right side of the copper busbar, which allows the copper busbar to pass through the inside of the connecting panel and connect to the circuit breaker. The connecting panel plays a role in fixing the copper busbar. A folding shaft is provided at the upper end of the copper busbar. The inner side of the folding shaft is folded by a rotating block, a rotating shaft and a circular hole, so that the folding shaft can drive the copper busbar to rotate 360°, making the installation area of ​​the copper busbar wider and the installation more convenient.

[0004] However, in the actual installation of the copper busbars to the current transformers mentioned in the above patent applications, there are different installation distances between different current transformers and copper busbars. However, the copper busbars cannot be adjusted, so the applicability is not strong. Generally, custom-made copper busbars are required, which is quite troublesome. Utility Model Content

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] A copper busbar structure for power input, such as Figures 1-6 As shown, it includes a copper busbar body 1, an insulating protective sleeve 2 covering the outside of the copper busbar body 1, a gasket 3 fixedly connected to one end of the outer wall of the copper busbar body 1, a gasket 4 movably disposed above the gasket 3, a waist groove 5 and two waist grooves 7 extending through the upper surfaces of both the gasket 3 and the gasket 4, bolts 6 inserted inside the two waist grooves 7, nuts 9 covering the outside of the two bolts 6, mounting grooves 18 opening near the four corners of the bottom surface of the gasket 4, a housing 12 fixedly installed inside the four mounting grooves 18, and mounting grooves 19 opening near the four corners of the upper surface of the gasket 3, fixing blocks 11 fixedly installed inside the four mounting grooves 19.

[0028] The two outer side walls of the fixing block 11 are provided with movable grooves 13 near the upper end. Each movable groove 13 is fitted with a locking block 15. The inner walls of the two movable grooves 13 are fixedly connected with spring plates 14, and one end of each spring plate 14 is fixedly connected to the locking block 15. The two inner side walls of the sleeve 12 are provided with several locking slots 16, which are evenly distributed and fit with the locking blocks 15. Under the action of the spring plate 14, one end of the locking block 15 can be driven into the locking slot 16, so that the position between the fixing block 11 and the sleeve 12 is fixed. The bottom of the bolt 6 is fixedly inserted into the copper busbar 1, and the first gasket 3 and the second gasket 4 are movably sleeved on the outside of the two bolts 6 through the second waist groove 7. The first mounting groove 18 provides installation space for the sleeve 12, and the second mounting groove 19 provides installation space for the fixing block 11. The insulating protective sleeve 2 plays a protective role for the copper busbar 1.

[0029] In use, one end of the copper busbar 1 is connected to the electrical component through the mounting hole 20, and the other end of the copper busbar 1 is connected to the current transformer. During installation, the distance between shim 1 3 and shim 2 4 can be adjusted according to the position of the current transformer so that one end of the copper busbar 1 can adapt to current transformers at different distances.

[0030] When adjusting the distance between shim 3 and shim 4, simply move shim 4 upward along bolt 6 via groove 7, causing sleeve 12 to move upward along the outside of fixing block 11. During the upward movement, the inclined surface of locking block 15 slides along the inner wall of slot 16. Under the continuous pressure of sleeve 12, locking block 15 can move into movable slot 13, and spring plate 14 is compressed and contracted until the position between shim 3 and shim 4 is adjusted. Under the action of spring plate 14's rebound force, one end of locking block 15 can be driven into slot 16, fixing the position between fixing block 11 and sleeve 12, thus conveniently completing the adjustment and fixing of the distance between shim 3 and shim 4.

[0031] A limiting groove 17 is provided on the inner wall of the waist groove 2 7. A nut 2 10 is threaded on the outside of the bolt 6 and located inside the limiting groove 17. Two grooves 8 are provided on the upper surface of the washer 2 4. An installation hole 20 is provided through the outer wall of the copper busbar 1 at the end away from the washer 3. The two grooves 8 can provide space to move the nut 2 10 and adjust the position of the nut 2 10 on the bolt 6.

[0032] Specifically, after adjusting the distance between gasket 3 and gasket 4, rotate the two nuts 9 onto the outside of the bolt 6 so that the bottom surface of the nuts 9 is in close contact with the outer wall of the gasket 4. By rotating the nuts 10 along the outside of the bolt 6, the gasket 4 is squeezed from bottom to top. With the help of the nuts 9, the position of the gasket 4 can be further clamped and fixed to prevent the gasket 4 from shifting. At this time, the gasket 3 and gasket 4 can be installed and fixed to the current transformer by external connectors, such as screws, and with the two grooves 5, thus completing the connection between the copper busbar 1 and the current transformer.

[0033] 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 claimed utility model.
