The limiting column 132f2 is arranged in the mounting groove 132f to be matched with the limiting hole 191 on the conductive sheet 19, so that the conductive sheet 19 is prevented from traversing in the mounting groove 132f, and the effect of further limiting the conductive sheet 19 is achieved; meanwhile, a clamping part 132f3 is arranged at the edge of the limiting groove 111, and the clamping part 132f3 clamps the edge of the conductive sheet 19 to prevent the conductive sheet 19 from being separated from the mounting groove 132 f. That is, in this solution, the fixing strength of the conductive sheet 19 is further improved by using the limiting post 132f2, the clamping portion 132f3, and the limiting hole 191, so as to further ensure the electrical connection stability between the conductive sheet 19 and the positive electrode terminal or the negative electrode terminal of the battery cell 131.

Alternatively, as shown in fig. 19, the battery module 1 further includes a protective cover body 130, the control circuit board 18 and the protective cover body 130 are mounted on the outer side surfaces of the upper and lower frames 132 and 133, and the protective cover body 130 is covered on the control circuit board 18. The protective cover 130 can effectively protect the control circuit board 18 and components thereon from the external environment and avoid the risk of failure caused by the entry of external substances onto the control circuit board 18. In addition, the protective cover 130, the control circuit board 18, the upper frame 132 and the lower frame 133 are assembled into a whole, so that the whole battery module 1 is simpler to assemble and disassemble and is easy to maintain.

The above description of the invention in connection with specific alternative embodiments is further detailed and it is not intended that the invention be limited to the specific embodiments disclosed. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the invention, and these should be considered to be within the scope of the invention.
