The set angle between the connection plate 12 and the end plate body 11 is identical to the included angle between the side surface and the top surface of the battery pack 3, and therefore, in other example embodiments of the present disclosure, in the case where the structure of the battery pack 3 is different, the set angle between the connection plate 12 and the end plate body 11 may not be 90 degrees, and a specific angle value is set according to the included angle between the side surface and the top surface of the battery pack 3.

In other example embodiments of the present disclosure, the length of the connection plate 12 in the second direction Y may be smaller than the length of the end plate body 11 in the second direction Y as long as the length of the connection plate 12 in the second direction Y can support all of the circuit boards 4.

A positioning card slot 121 is arranged on the connecting plate 12, and the positioning card slot 121 is used for clamping the circuit board 4. Specifically, the positioning clamping groove 121 is arranged on one side surface of the connecting plate 12 far away from the end plate body 11, and the depth of the positioning clamping groove 121 is smaller than the thickness of the connecting plate 12, that is, the positioning clamping groove 121 does not penetrate through the connecting plate 12, but is arranged as a blind groove with a bottom wall, so that the strength of the connecting plate 12 can be ensured, and the limiting of the circuit board 4 is increased in one direction, that is, the circuit board 4 is partially limited in the third direction Z; on the other hand, when the pressing plate presses down the end plate 1 during the process of placing the battery pack 3 into the box, the solid body of the surface of the connecting plate 12 contacting the battery cell 31 can transmit part of the pressure to the battery cell 31, so as to avoid pressing only the end plate 1, and thus the end plate 1 is separated from the battery pack 3 due to the pressure.

In the present exemplary embodiment, since four rows of the unit cells 31 require four circuit boards 4, four positioning card slots 121 are provided on the connection board, one positioning card slot 121 corresponding to one circuit board 4. Of course, in the case where the number of circuit boards 4 is changed, the number of positioning card slots 121 is also changed.

For example, in the case where the end portion of the circuit board 4 is provided in a straight plate shape, the positioning card slot 121 is provided as a straight groove; in the case where the end portion of the circuit board 4 is formed in an arc plate shape, the positioning card slot 121 is formed in an arc groove; under the condition that the end part of the circuit board 4 is provided with a turning structure, the positioning clamping groove 121 is also provided with the turning structure; in the case where the end portion of the circuit board 4 is provided with another special structure, the positioning card slot 121 is also provided with another special structure. And the width of the positioning card slot 121 in the second direction Y is the same as the width of the circuit board 4 in the second direction Y, so that the positioning card slot 121 can clamp and position the corresponding end of the circuit board 4, and the circuit board 4 is prevented from moving.

In the present exemplary embodiment, the positioning card slot 121 penetrates the connection board 12 in the first direction X, that is, the positioning card slot 121 is provided as a through slot penetrating the connection board 12, so that the circuit board 4 can be accommodated in the positioning card slot 121 also in the case where the circuit board 4 is long. Of course, in other example embodiments of the present disclosure, one end of the positioning clamping groove 121 close to the end plate body 11 may be provided with a groove wall, that is, the positioning clamping groove 121 is not provided as a through groove penetrating through the connecting plate 12.

Because the positioning clamping groove 121 needs to ensure that the corresponding end of the circuit board 4 can be clamped and positioned, the width of the connecting plate 12 is wide, and the connecting plate 12 can shield the battery post 311 and the explosion-proof valve 312. In order to solve the above problem, in the present exemplary embodiment, the connection plate 12 is further provided with a first escape portion 122, and the first escape portion 122 is used to escape the battery post 311.

In the present exemplary embodiment, the battery post 311 is configured as a cylinder, and the first avoiding groove 124 is configured as a semicircular groove adapted to the battery post 311. The radius of the semicircular groove may be equal to or slightly larger than the radius of the battery post 311. In addition, in other exemplary embodiments of the present disclosure, in the case that the battery post 311 is provided as a prism, the first avoiding groove 124 is provided as a rectangular groove or a polygonal groove adapted to the battery post 311. Of course, the first avoiding groove 124 and the battery post 311 may also have other special shapes, which are not described herein again.

In still other example embodiments of the present disclosure, as shown in fig. 2, in a case where the width of the connection plate 12 is set wider to shield the entire battery post 311, the first escape portion 122 may also be provided as a through hole penetrating the connection plate 12. The shape of the through hole is adapted to the battery post 311, for example, in the case that the battery post 311 is configured as a cylinder, the through hole is configured as a circular through hole; in the case where the battery post 311 is provided as a prism, the through-hole is provided as a polygonal through-hole.

In the present exemplary embodiment, the explosion-proof valve 312 may be disposed in a waist-round shape, and the second avoidance groove 125 may be disposed in a rectangular groove; and the orthographic projection of the edge of the second avoiding groove 125 on the battery pack 3 is not overlapped with the explosion-proof valve 312, so that the connecting plate 12 does not shield the explosion-proof valve 312 at all.

In addition, in other exemplary embodiments of the present disclosure, the second avoidance groove 125 may be adapted to the explosion-proof valve 312, for example, the second avoidance groove 125 may be configured as a semicircular groove corresponding to the above-mentioned waist-round shape of the explosion-proof valve 312. In the case where the explosion-proof valve 312 is provided in a rectangular or polygonal shape, the second escape groove 125 may be provided in a rectangular or polygonal shape to be fitted to the explosion-proof valve 312. Of course, the second avoiding groove 125 and the explosion-proof valve 312 may also be in other special shapes, which are not described herein again.
