It will be appreciated that if the post is a rectangular solid, the through hole 101 is rectangular.

The pole connecting part 2 includes an end cap 21 and a support member 22, the end cap 21 is disposed above the through hole 101 at an interval, the support member 22 is connected between the end cap 21 and the hole edge 102 of the through hole 101, and the support member 22 is provided with a fuse hole 221.

The support 22 supports the end cap 21 above the tab connection body 10, and the pole can protrude from the through hole 101 between the area defined by the end cap 21 and the support 22.

The supporting member 22 is provided with a fusing hole 221, and when the current of the battery connecting plate is overloaded, the supporting member 22 is fused from the edge of the fusing hole 221, thereby preventing the current from being continuously overloaded. The fusing area is located on the pole connecting part 2, the upper space of the pole lug connecting part 1 is utilized, the fusing area is prevented from being arranged on the pole lug connecting body 10 in the prior art, the setting range of the weldable area is not influenced, the pole lug connecting part 1 can be set to be smaller, and the production cost of the battery connecting piece is reduced.

In order to accelerate the fusing efficiency, at least two fusing holes 221 are formed on the supporting member 22, in this embodiment, three fusing holes 221 are formed on the supporting member 22, and the supporting member 22 can be fused between two adjacent fusing holes 221. It can be understood that the greater the number of the fusing holes 221, the faster the fusing speed of the supporting member 22.

In this embodiment, each of the fuse holes 221 is a strip-shaped hole parallel to the hole edge 102. In other words, the extension length of a single fuse hole 221 is much greater than the interval between two adjacent fuse holes 221.

In order to facilitate the manufacture of the fusing holes 221, in the present embodiment, the length and the height of each fusing hole 221 are the same. That is, a punching device may be used to punch holes in the supporting member 22 to prepare the fuse holes 221 having the same size.

I.e., the interval between two adjacent fusing holes 221 is also the same.

In order to make the fusing efficiency at each fusing hole 221 the same, in this embodiment, the interval angle between any two adjacent fusing holes 221 is the same, that is, the distance between two adjacent fusing holes 221 is the same.
