Embodiment Construction

[0010] Below in conjunction with embodiment the present invention is further described.

[0011] Such as figure 1 As shown, a combination pole of a power battery includes a terminal 1 and a connecting column 2. A groove 11 is provided on the terminal 1. The cross section of the groove 11 is polygonal, and a through hole 12 is provided in the groove; the connecting column One end of 2 is provided with a terminal 21 matching with the groove 11, and the connecting column shaft 22 passes through the through hole 12 of the groove.

[0012] There is an interference fit between the connecting post 2 and the terminal 1 . Interference fit can improve the conductivity between the two.

[0013] The cross section of the groove 11 is hexagonal. Other shapes are also possible, such as triangles, rectangles, pentagons, and the like.

[0014] The connecting column 2 is made of stainless steel, which solves the problem that the copper / aluminum studs cannot meet the torsion requirement and ...

Abstract

A combination type pole for a power battery relates to a positive pole and a negative pole of a power battery cover plate. The combination type pole for the power battery comprises a terminal (1) and a connecting column (2). The terminal (1) is provided with a groove (11); a cross section of the groove (11) is a polygon; and a through hole (12) is arranged in the groove. One end of the connecting column (2) is provided with an end (21) cooperating with the groove (11); and a connecting column body (22) passes through the through hole (12) of the groove. The invention can meet torque requirements between the poles.

Description

technical field [0001] The invention relates to positive and negative poles of a power battery cover plate. Background technique [0002] The whole world is advocating environmental protection and energy saving. In terms of transportation, the only vehicle that can bring green and environmental protection is new energy vehicles. The power of new energy vehicles comes from power batteries, and solar power requires energy storage power batteries. The new energy vehicle power battery connection method is that multiple batteries are combined to provide power energy to the car through the connection between the terminal studs and the terminal studs. Existing terminal studs are all formed by copper / aluminum bar lathing. When the battery stud is connected to another battery stud, it is difficult to ensure the integrity of the thread of the stud, and the copper / aluminum pole has no way to meet the torque requirement. Contents of the invention [0003] The purpose of the present i...
