The conductive sheet has at least one cavity portion. Each of the at least two bridge portions has a first end and a second end which are opposite to each other, and the first ends of the bridge portions are respectively connected to different sides of the at least one cavity portion. The terminal contact portions are spaced apart from each other and are respectively connected to the second ends of the bridge portions. A width direction is defined to be substantially perpendicular to a line passing through the first end and the second end of one of the at least two bridge portions; along the width direction, a width of the bridge portion is smaller than a width of the terminal contact portion. ## Claims ### Claim 1 A battery busbar, comprising: a conductive sheet, having at least one cavity portion; at least two bridge portions, each of the at least two bridge portions having a first end and a second end which are opposite to each other, and the first ends of the at least two bridge portions respectively connected to different sides of the at least one cavity portion; and at least two terminal contact portions, spaced apart from each other and respectively connected to the second ends of the at least two bridge portions, wherein a width direction is defined to be substantially perpendicular to a line passing through the first end and the second end of one of the at least two bridge portions; along the width direction, a width of the bridge portion is smaller than a width of the terminal contact portion. ### Claim 2 (depends on 1) The battery busbar according to claim 1, wherein the at least two bridge portions are respectively connected to two opposite sides of the at least one cavity portion. ### Claim 3 (depends on 1) The battery busbar according to claim 1, wherein the at least two bridge portions are bendable with respect to the conductive sheet, such that the at least two terminal contact portions are able to be bent to be non-coplanar with the conductive sheet. ### Claim 4 (depends on 1) The battery busbar according to claim 1, wherein the conductive sheet, the at least two terminal contact portions and the at least two bridge portions are made of one piece. ### Claim 5 (depends on 1) The battery busbar according to claim 1, wherein each of the at least two bridge portions has a pre-made notch. ### Claim 6 (depends on 1) The battery busbar according to claim 1, wherein each of the at least two bridge portions has at least one pre-made cut-off. ### Claim 7 (depends on 1) The battery busbar according to claim 1, wherein the conductive sheet is independent from the at least two terminal contact potions and the at least two bridge portions. ### Claim 8 (depends on 7) The battery busbar according to claim 7, wherein the conductive sheet includes a first part and a second part which are independent from each other, the first part is fixed at a side of the second part, the at least one cavity portion penetrates through the first part and the second part, and the first part, the at least two terminal contact portions and the at least two bridge portions are made of one piece. ### Claim 9 (depends on 1) The battery busbar according to claim 1, wherein a shape, formed by the at least two terminal contact portions, matches a shape of a terminal of a battery. ### Claim 10 (depends on 1) The battery busbar according to claim 1, wherein each of the at least two terminal contact portions is in a semicircle shape, and each of the at least two bridge portions is in an elongated shape. ### Claim 11 (depends on 1) The battery busbar according to claim 1, wherein each of the at least two terminal contact portions is in a C shape, and each of the at least two bridge portions is in an elongated shape. ### Claim 12 (depends on 1) The battery busbar according to claim 1, wherein the at least two terminal contact portions get together and form a fix hole. ### Claim 13 (depends on 1) The battery busbar according to claim 1, wherein the quantity of the at least one cavity portion is plural. ### Claim 14 (depends on 1) The battery busbar according to claim 1, wherein the at least two terminal contact portions and the at least two bridge portions are the same in quantity.
