Description

Technical Field

[0001] This utility model relates to the technical field of flexible connections, specifically to a locally hardened flexible copper busbar. Background Technology

[0002] A flexible connection is a specially designed, flexible electrical connection component used to establish a reliable, low-resistance conductive path between two rigid copper busbars or equipment terminals, while allowing a certain degree of relative displacement or vibration.

[0003] Currently, only the two ends of a soft connector are rigid and can be fixed, while the middle is flexible. This limits the application scenarios of soft connectors, such as small spaces and special irregular shapes, and it also cannot achieve splicing and connection of individual soft connectors. Utility Model Content

[0004] To address the aforementioned issue of the limited application scenarios of existing flexible connections, this invention proposes a partially hardened flexible copper busbar, which includes a flexible portion and a plurality of hardened portions. The hardened portions are circular and are used to contact devices. Fixing holes are provided within the hardened portions for fixing the devices.

[0005] A further feature of this invention is that the hardened part includes four large fixing positions and three small fixing positions, one of the large fixing positions is located in the middle of the flexible part, the other three large fixing positions are arranged in an equilateral triangle, and the three small fixing positions are also arranged in an equilateral triangle.

[0006] A further feature of this invention is that the flexible part is circular.

[0007] A further feature of this invention is that the hardened part is selected as a molybdenum sheet.

[0008] This invention also proposes a partially hardened flexible copper busbar, including a flexible portion, on which a plurality of hardened portions are equidistantly arranged along its length direction. The hardened portions are used to contact devices, and fixing holes are provided in the hardened portions for fixing the devices.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. The multiple hardened sections allow for arbitrary adjustment of the copper busbar's installation position and angle based on the connection or fixing method, greatly expanding application scenarios and reducing installation space. This solves the problems of difficult splicing of multiple soft connections and stress concentration.

[0011] 2. By selecting molybdenum sheets as the hardening part, their coefficient of thermal expansion is made closer to that of semiconductor materials, thereby greatly reducing the thermal stress problem caused by thermal expansion. Attached Figure Description

[0015] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0016] Example 1

[0017] refer to Figure 1 A partially hardened flexible copper busbar is proposed, including a flexible part 1, which is circular, and seven hardened parts 2 are provided on the flexible part 1. The hardened parts 2 are circular and are fixedly connected to the flexible part 1. The hardened parts 2 are used to contact the device and realize electrical connection. A fixing hole is provided at the center of the hardened part 2 for tightening and fixing the connected device.

[0018] The hardened part 2 includes four large fixing positions 21 and three small fixing positions 22. One of the large fixing positions 21 is located in the middle of the flexible part 1 and is coaxial with the flexible part 1. The other three large fixing positions 21 are arranged in an equilateral triangle with the center of the flexible part 1 as the center. The three small fixing positions 22 are also arranged in an equilateral triangle with the center of the flexible part 1 as the center.

[0019] Molybdenum sheet is selected for the hardening part 2 because copper busbars are mostly used in semiconductor connections, and the main material of semiconductors is silicon. The thermal expansion coefficient of molybdenum sheet is close to that of silicon, which can greatly reduce the thermal stress caused by thermal expansion during use.

[0020] Example 2

[0021] refer to Figure 2 A partially hardened flexible copper busbar also includes a flexible part 1, on which six hardened parts 2 are equidistantly arranged along its length direction. The hardened parts 2 are used to contact the device, and the hardened parts 2 are provided with fixing holes for fixing the connected device.

[0022] It should be noted that the hardening part 2 in this embodiment also uses a molybdenum sheet, and its function is the same as that in embodiment 1, which is to reduce the thermal stress caused by thermal expansion.

[0023] In summary, the multiple hardened parts 2 of this invention allow for arbitrary adjustment of the installation position and angle of the copper busbar according to the connection or fixing method, greatly expanding the application scenarios and reducing the installation space. It also solves the problems of difficult splicing of multiple flexible connections and stress concentration. By selecting molybdenum sheets as the hardened parts 2, their coefficient of thermal expansion is closer to that of semiconductor materials, thereby significantly reducing the thermal stress caused by thermal expansion.
