It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0028] Furthermore, the use of terms such as "first" and "second" in the embodiments of this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0029] This embodiment of the invention provides a high-current copper busbar structure with a 90-degree magnetic ring. By setting the copper busbar used to transmit current as two welded first connecting units 100 and second connecting units 200, different cross-sectional areas can be set to more accurately adapt to different current transmissions, while saving production costs. In particular, this embodiment also includes a shielding unit 300 composed of a magnetic ring 310, which can shield the current and prevent interference from other external currents, thus affecting the stability and accuracy of current transmission.

[0030] Specifically, such as Figure 1-3As shown, 1. A high-current copper busbar structure with a 90-degree magnetic ring includes a first connecting unit 100, a second connecting unit 200, a shielding unit 300, and a housing 400. The first connecting unit 100 includes at least two first conductors 110 arranged side-by-side. One end of each first conductor 110 has a connecting end 111 extending along a first predetermined direction, and the other end is bent along a second predetermined direction to form a mating end 112. The second connecting unit 200 includes components respectively connected to the first conductors... A number of second conductors 210 corresponding to the first conductor 110 are provided. One end of the second conductor 210 is fixedly connected to the docking end 112, and the other end extends outward. The shielding unit 300 includes a number of magnetic rings 310 corresponding to the first conductor 110. The magnetic rings 310 are fitted onto the connecting end 111. The housing 400 is injection molded onto the first connecting unit 100 and the second connecting unit 200, and the end of the connecting end 111 and the end of the second conductor 210 away from the first conductor 110 extend along the housing 400.

[0031] During use, the connecting end 111 of the first conductor 110 is used for electrical connection with a conductor, and the second conductor 210 is fixedly connected to the docking end 112 of the first conductor 110. In this embodiment, one end of the second conductor 210 is fixedly connected to the docking end 112 by welding, and the other end of the second conductor 210 is connected to the first conductor 110. In this embodiment, the first predetermined direction and the second predetermined direction form a right angle, and a magnetic ring 310 is fitted on the connecting end 111 of the first conductor 110, thereby shielding the signal during current transmission and preventing external signals from affecting the signal transmission of this copper busbar, while also preventing the copper busbar from emitting interference signals during signal transmission. The technical solution provided by this embodiment can ensure the stability and reliability of the signal during transmission. Meanwhile, the copper busbar used for current transmission is equipped with a first conductor 110 and a second conductor 210 that are interconnected. The cross-sectional areas of the two conductors can be set to different sizes, and the two conductors can also be set to different hardnesses. In this embodiment, the hardness of the first conductor 110 is greater than that of the second conductor 210, that is, the first conductor 110 is set as the main busbar. The second conductor 210 can be adjusted in any direction according to the actual connection requirements, thereby improving the convenience of connection. At the same time, because the cross-sectional areas of the two conductors are different, the current carrying capacity can be increased by increasing the cross-sectional area of ​​the second conductor 210.

[0032] In this embodiment, the spacing between each connecting end 111 is greater than the spacing between each second conductor 210; at least one mating end 112 is formed with a bent portion 113 that bends and extends toward the adjacent mating end 112, and at least one second conductor 210 is fixedly connected to the extension portion. In this embodiment, three first conductors 110 are provided, and the mating ends 112 of the two first conductors 110 at both ends are provided with bent portions 113 that bend and extend toward the middle first conductor 110. The two second conductors 210 at both ends are welded to the bent portions 113, thereby making the spacing between the three second conductors 210 smaller than the spacing between the connecting ends 111 of the three first conductors 110. This minimizes the component space and volume while meeting the minimum spacing design requirements of electrical design.

[0033] In this embodiment, the housing 400 includes a main body portion 410 and a secondary body portion 420. The main body portion 410 is used to cover the connecting end 111 and the magnetic ring 310. The secondary body portion 420 is formed with the main body portion 410 and extends along the extending direction of the mating end 112 to cover the mating part and the second conductor 210, so that a right angle is defined between the secondary body portion 420 and the main body portion 410.

[0034] In this embodiment, to facilitate the installation of the copper busbar, a notch 411 is provided on the main body 410 at a position corresponding to the magnetic ring 310, allowing a portion of the magnetic ring 310 to be exposed. This exposure of the magnetic ring 310 facilitates attraction between the magnetic ring 310 and the magnetic components of the mounting parts, thereby improving the stability of the installed copper busbar.

[0035] In this embodiment, the housing 400 is fixed to the first connector and the second connector through the main body. In order to avoid supporting the magnetic ring 310 during the injection molding process and to avoid cracking of the housing 400 during the injection molding process, a process hole 412 is provided on the main body 410 at a position corresponding to the magnetic ring 310, and part of the magnetic ring 310 is exposed along the process hole 412.

[0036] In this embodiment, to improve the insulation capability between the second conductors 210, an isolation groove 421 is provided on the sub-body portion 420 above the two second conductors 210. The isolation groove 421 is provided on the side wall of the sub-body portion 420 and extends from the upper end of the sub-body portion 420 to the position where the sub-body portion 420 and the main body portion 410 are connected. By providing the isolation groove 421, the creepage isolation capability between the two second conductors 210 can be improved, thereby improving the insulation performance.

[0037] In this embodiment, to improve the adaptability of the housing 400 during installation, a plurality of connecting holes 401 are formed on the housing 400, and at least some of the connecting holes 401 are provided with internal threads. The connecting holes 401 can be configured as through holes, thereby facilitating bolt connection with connecting parts, and internal threads can also be provided in some of the connecting holes 401 to achieve threaded connection with other components.

[0038] For those skilled in the art, various other corresponding changes and modifications can be obtained based on the structure and principles disclosed in this utility model, and all such changes and modifications fall within the protection scope of this utility model.
