Abstract: The present disclosure provides a connecting assembly and a battery pack, the connecting assembly comprises a busbar, a first insulating sleeve, a second insulating sleeve and a third insulating sleeve. The busbar comprises a main body portion, an extending portion, and a bent connection portion. The first insulating sleeve covers the main body portion. The second insulating sleeve covers the extending portion. The third insulating sleeve comprises a first covering portion, the first covering portion covers the bent connection portion. Because the first insulating sleeve, the second insulating sleeve and the third insulating sleeve are independent components, and they segmentally cover different parts of the busbar, so that each of them has a shorter length and less portion required to be bent, thereby facilitating the first insulating sleeve, the second insulating sleeve and the third insulating sleeve to be respectively sheathed on the different parts of the busbar.
