Description

Novel busbar connection structure

Technical Field

The utility model relates to a female structure of arranging that uses in new forms of energy battery package especially relates to a novel female connection structure that arranges.

Background

The busbar (busbar) is an important part in the new energy battery pack and plays a role in conveying current and connecting electrical equipment in a circuit. The surface of the busbar is usually wrapped by an insulating skin, and the end part is exposed to realize electric connection. The common bus bar inner core is made of oxygen-free copper materials, the end part of the common bus bar inner core is exposed outside for a long time, and the common bus bar inner core is inevitably oxidized to influence the electrical property of the common bus bar inner core. The main technology at present is to solve the problem of oxidation by means of local electroplating or local welding of nickel sheets, but both methods have certain limitations. For local electroplating, a clamping piece needs to be arranged aiming at the busbar structure, clamping and dismounting of the busbar are involved in the electroplating process, the equipment cost and the labor cost are high, and economic benefits are not met. The welding process has higher difficulty coefficient, and the welding effect is difficult to control.

In order to realize the oxidation resistance of the busbar, the engineer designs that a gasket structure is arranged on the busbar. In the initial design process, the gasket is installed by adopting a through hole structure, and the gasket is as high as the through hole structure. But due to tolerances it is difficult to achieve a gasket top surface that is perfectly flush with the via top surface. If the height of gasket is greater than the degree of depth of through-hole when the bolt structure of installation in the through-hole, there is the risk that the bolt will push out the through-hole with the gasket. If the height of gasket is less than when the degree of depth of through-hole, lack the support to the generating line, the pressure to the generating line surface is great when the bolt is screwed up, makes the generating line surface take place deformation easily.
