Separator assembly and battery module

Abstract

The present invention provides a separator assembly and a battery module. The separator assembly includes a separator and a plurality of electrical connecting sheets. The separator is provided with aplurality of supporting parts and a plurality of first limiting parts. There is a space between each first limiting part and a corresponding supporting part along the height direction. Each electricalconnecting sheet has a first end and a second end which is arranged opposite to the first end in the width direction. The first end of each electrical connecting sheet is accommodated in the corresponding space and is clamped and fixed by the corresponding first limiting part and supporting part. The second end extends to the outside of the supporting part in the width direction. In the process of assembly, the first end of each electrical connecting sheet can be directly inserted into the corresponding space from one side of the separator in the width direction. The assembly method is simpleand fast, and the assembly efficiency is improved. Since the first end of each electrical connecting sheet is supported above the corresponding supporting part and the second end extends to the outside of the supporting part in the width direction, the volume of the separator is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an isolation plate assembly and a battery module. Background technique [0002] The isolation plate assembly generally includes an isolation plate and an electrical connection piece, and the function of the isolation plate is to limit the position of the electrical connection piece. However, the traditional isolation plate components generally have the following problems: (1) most of the isolation plates cannot provide a fixing force for the electrical connector in the height direction, resulting in the risk of the electrical connector falling off under vibration conditions; (2) Although some isolation boards can provide fixing force for the electrical connectors in the height direction, it is necessary to place the electrical connectors on the isolation board from top to bottom. In order to facilitate assembly, the fixing structure on the isolation board will reserve a certain...

Problems solved by technology

However, the traditional isolation plate components generally have the following problems: (1) most of the isolation plates cannot provide a fixing force for the electrical connector in the height direction, resulting in the risk of the electrical connector falling off under vibration conditions; (2) Although some isolation boards can provide fixing force for the electrical connectors in the height direction, it is necessary to place the electrical connectors on the isolation board from top to bottom. In order to facilitate assembly, the fixed structure on the isolation board will reserve a certain amount of space for assembly. space, resulting in low reliability of fixing between the isolation board and the electrical connection sheet; (3) The overall structure of the isolation board assembly is complex and bulky, which is not conducive to cost reduction
