Abstract
Description
Technical Field
[0001] This utility model relates to the field of capacitor busbar technology, specifically to a hybrid material welded capacitor busbar. Background Technology
[0002] Currently, existing capacitor busbars are widely used in new energy vehicles, electronic and electrical equipment, DC power transmission and distribution, electric locomotives, wind power, and solar power grid connection. Since the main body of the capacitor busbar needs to be welded and fixed to the capacitor core, installation also requires welding through connection structures such as output terminals and input terminals. To meet welding requirements, the main body of existing capacitor busbars is mostly made of copper. The main body of the capacitor busbar usually accounts for a large area, and if copper is used directly, the material cost will be relatively high. If aluminum-clad copper is used, although it can meet the welding requirements of the capacitor core, its material yield and rate recovery rate are relatively low, leading to even higher production costs. Therefore, there is an urgent need to provide a capacitor busbar structure that can reduce the use of copper to lower production costs. Utility Model Content
[0003] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a hybrid material welded capacitor busbar that can reduce the amount of copper material used and reduce product production costs.

[0005] In this technical solution, the busbar body used for mounting and connecting capacitor cores is equipped with output terminals and connection terminals. The connection terminals are used for welding to the output end of the capacitor cores, and the output terminals are used for welding to the connecting equipment. Both the connection terminals and the output terminals are made of copper, which can be welded and fixed to ensure the stability of the installation connection and guarantee the quality of product use. Since the busbar body is made of aluminum, welding it to the connection terminals and output terminals can significantly reduce the amount of copper used in the capacitor busbar, thereby reducing production costs while ensuring product quality.
[0006] Preferably, the busbar body is provided with a plurality of spaced mounting slots, one end of the connecting terminal is welded to the busbar body, and the other end extends into the center of the mounting slot.
[0007] Preferably, the connection terminal has welding parts at both ends, one welding part is welded to the busbar body, and the other welding part is welded to the capacitor core output end.

Both the connection terminals and the output terminals are made of copper material, which can be welded and fixed to ensure the stability of the installation connection and guarantee the quality of product use.

[0014] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0015] like Figure 1 As shown in the figure, a specific embodiment of this utility model provides a hybrid material welded capacitor busbar, including a busbar body 100, on which a plurality of output terminals 200 and connection terminals 300 are provided; the busbar body 100 is made of aluminum material, and the output terminals 200 and connection terminals 300 are made of copper material, and the output terminals 200 and connection terminals 300 are welded to the busbar body 100.
[0016] like Figure 1As shown, with the above configuration, the capacitor busbar provided in this embodiment is used to install the capacitor core 400; and the busbar body 100 is provided with an output terminal 200 and a connection terminal 300. The connection terminal 300 is used to weld to the output end of the capacitor core 400, and the output terminal 200 is used to weld to the connecting device. Both the connection terminal 300 and the output terminal 200 are made of copper material, which can be welded and fixed to ensure the stability of the installation connection and guarantee the quality of product use. Since the busbar body 100 is made of aluminum material, welding it to the connection terminal 300 and the output terminal 200 can significantly reduce the amount of copper material used in the capacitor busbar, thereby reducing production costs while ensuring product quality.
[0017] like Figure 1 As shown, to facilitate the connection of the capacitor cores 400, this embodiment has a plurality of spaced mounting slots 110 on the busbar body 100. One end of the connecting terminal 300 is welded to the busbar body 100, and the other end extends into the center of the mounting slot 110.

The connecting terminal 300 and the output end of the capacitor core 400 are electrically connected by welding.
[0018] like Figure 1 As shown, in this embodiment, welding portions are provided at both ends of the connecting terminal 300. One welding portion is welded to the busbar body 100, and the other welding portion is welded to the output end of the capacitor core. By providing welding portions, the welding area is increased. The welding portions can be set into elliptical or other structures, which can improve the stability and firmness of the connection between the connecting terminal 300 and the busbar body 100 and the capacitor core.
[0019] As mentioned earlier, the capacitor busbar needs to be fixed to the capacitor core. External mounting equipment is connected via the output terminals 200. In this embodiment, a bent output section 120 is provided at the end of the busbar body 100 and on one side edge of the busbar body 100. Each output terminal 200 is welded and fixed to the output section 120. Thus, after the output section 120 is bent outwards, each output terminal 200 can be stably mounted on the output section 120, facilitating installation and connection.
