Abstract

The invention discloses an adapter piece, a secondary battery and a battery module. The adapter piece comprises a first connecting part, a fusing part, a second connecting part and an insulating part, the fusing part is located between the first connecting part and the second connecting part and is connected with the first connecting part and the second connecting part, a first disconnecting part and a second disconnecting part which are arranged at an interval are formed after the fusing part is fused, and the insulating part is used for fixing the first disconnecting part and the second disconnecting part. Therefore, the fused fusing part is stabilized, secondary contact between the first disconnecting part and the second disconnecting part due to shaking of the battery is avoided, and the safety of the battery is further improved.

Description

technical field [0001] The invention relates to the technical field of secondary batteries, in particular to an adapter piece, a secondary battery and a battery module. Background technique [0002] With the development of society, secondary batteries are used more and more widely. A secondary battery refers to a battery that can be activated by charging the active material after the battery is discharged and continues to be used. The adapter piece of the secondary battery in the prior art is used to connect the corresponding electrode lead-out terminal on the top cover and the corresponding tab on the battery cell. There is a fuse position on the adapter piece. When the battery core is short-circuited or overcharged or over-discharged, the heat generated at the fuse position is relatively high, so it is the first to fuse. Once in contact, there is a certain safety risk. Contents of the invention [0003] The present application provides an adapter piece, a secondary ba...
