Embodiments of the present invention provide a sampling component and a battery module. The sampling component is applied to a battery module and comprises: a busbar having a first surface and a second surface which are opposite to each other, the busbar comprising mounting slots formed by extending in a direction from the first surface to the second surface; a circuit board disposed on a side of the busbar; and, a connecting sheet, comprising a first flat portion and a bent portion which are connected to each other, one end of the first flat portion being connected to the busbar while the other end thereof being connected to the circuit board, the bent portion being located in the mounting slots.

Sampling component and battery module

The present disclosure provides a battery module, which comprises: a plurality of mono-batteries, each mono-battery has electrode terminals which are opposite in electrical polarity; and an electrical connection sheet connecting at least two corresponding electrode terminals, the electrical connection sheet is formed with at least one fusing portion, each fusing portion is positioned between two adjacent electrode terminals. The battery module further comprises: an insulating sheet supported on the fusing portion which is positioned between the two adjacent electrode terminals connected by the electrical connection sheet, when the fusing portion supporting the insulating sheet is fused and a fracturing slit is formed, the insulating sheet drops into the fracturing slit to electrically isolate two facing sides of the electrical connection sheet which are at the fracturing slit. Therefore it avoids the phenomenon of an electrical arc occurring at the fracturing slit and makes the electrical arc extinct.
