Problems solved by technology

[0004] The above-mentioned collective battery structure may be suitable for small-capacity collective batteries, but it cannot be applied to large-capacity collective batteries because of the large number of individual batteries inside and usually complicated series or parallel connections.

Embodiment Construction

[0036] First, if Figure 2-6 As shown in the figure, the terminal head structure of the assembled battery provided by the embodiment of the present invention, the assembled battery 50 is electrically connected by a plurality of individual batteries 51 through a conductive sheet 52 to form a common positive output terminal 53 and a negative electrode. The output end 54 is formed, and the terminal head structure is composed of a base part 20 , an insulating part 30 and a top part 40 .

[0037] The base part 20 is a conductive member and has a main board 21. Two corresponding surfaces of the main board 21 are respectively defined as a bottom surface 211 and a top surface 212, and two corresponding ends of the main board 21 are respectively formed with an assembly end 22 and An output terminal 23 . The assembly end 22 is located on the two corresponding sides of the top surface 212, and each of the two corresponding sides of the top surface 212 is vertically formed with a first t...

Abstract

The invention discloses a terminating electrode head structure for an assemble cell. The structure is formed by sequentially overlapping a base part, an insulating part and a top part. The structure is easy to assemble and has smooth surface after assembling. The base part and the top part are safely separated. In addition, the insulating part shields the main body of the base part, and only first and second interconnecting pieces are exposed, therefore reducing the short circuit risk of the base part and the top part due to false touch of metal objects. Two sides of the base part and that of the top part are respectively equipped with the first and second interconnecting pieces and connecting sheets. According to the invention, connection points are dispersed by a multipoint design, which is of great importance for the assemble cell with large quantity of electricity. Therefore, the temperature-rise problem caused by heating due to high single point impedance can be solved.

Description

technical field [0001] The invention relates to a terminal pole head structure of a collection battery, in particular to the terminal pole head structure of a collection battery formed by connecting a plurality of individual batteries inside. Background technique [0002] Based on the actual demand for high-output batteries, the common technology in the battery industry is to connect a large number of individual batteries in series or in parallel to form a collection battery with high output power. [0003] At present, the battery industry has not made further structural design for the power output of large-capacity collective batteries, but most of them directly output power after simple welding of metal sheets, such as figure 1 As shown, this is U.S. Patent No. 7,316,863. The set battery 10 is provided with a plurality of individual batteries 11, and each individual battery 11 is electrically connected through a metal conductive sheet 12, and then connected to a positive e...
