Description

Technical Field

[0001] The present application relates to the technical field of aluminum busbars, and specifically to an aluminum busbar for series connection of batteries. Background Art

[0002] A battery is a cup, tank or other container or part of a composite container that contains electrolyte solution and metal electrodes to generate current. It is a device that can convert chemical energy into electrical energy. It has positive and negative electrodes. With the development of technology, power batteries can be used as the core power source of electric vehicles or hybrid vehicles. Power batteries are composed of dozens, hundreds or even thousands of batteries connected in series and parallel, and the connection terminals of each battery are aluminum bars.

[0003] Currently, most of the aluminum bars for connecting batteries in series are fixed structures, which cannot be adjusted according to the actual requirements of connecting batteries in series during use, resulting in a small application range of the aluminum bars for connecting batteries in series. Therefore, those skilled in the art provide an aluminum bar for connecting batteries in series to solve the problems raised in the above background technology. Utility Model Content

After the positioning bolt is separated from the first pressure rivet, the nut is loosened, and the second aluminum row is rotated to both ends of the first aluminum row, so that the length of the first aluminum row can be better adjusted to meet the series connection requirements of different distances. At the same time, the second aluminum row can be rotated to different directions and connected to batteries at different positions, so that the series connection of the batteries can be better completed. The structure is simple, the adjustment operation is convenient, and the use is flexible.

[0011] Preferably, grooves are formed on both sides of the first aluminum row and the second aluminum row.

The flat gasket can better protect the surface of the second aluminum row and reduce the risk of detachment of the fixing bolt under the action of the spring gasket.

[0015] Preferably, two heat shrink sleeves are symmetrically arranged on the outer side of the first aluminum bar, and the two heat shrink sleeves are both provided with notches on one side of the joint between the second aluminum bar and the first aluminum bar.

[0016] By adopting the above technical solution, a heat shrink tube is arranged on the first aluminum bar to protect the first aluminum bar, and at the same time, the provided notch prevents the heat shrink tube from being sandwiched between the second aluminum bar and the first aluminum bar to affect the conductivity.

[0017] Preferably, thermal conductive silicone grease is applied on the joint between the heat sink and the first aluminum row.

[0018] By adopting the above technical solution, the thermal conductivity between the first aluminum row and the radiator can be enhanced under the action of the thermal conductive silicone grease, which is beneficial for the radiator to better dissipate the heat of the first aluminum row.

[0019] Preferably, connection holes are provided at both ends of the first aluminum bar.

[0020] By adopting the above technical solution, the opened connection holes are convenient for connection with the electrodes of the battery and can also be used for connection between adjacent first aluminum rows.

At the same time, the second aluminum bar can be rotated to different directions to connect with batteries at different positions, so as to better complete the series connection of batteries. It has a simple structure, convenient adjustment operation and flexible use.

[0024] 2. The battery is connected in series with aluminum bars, and a radiator is installed on the first aluminum bar, and grooves are provided on the outsides of the first aluminum bar and the second aluminum bar, which is beneficial to the heat dissipation of the first aluminum bar and the second aluminum bar, and the heat dissipation effect is better.
