For example, as shown in fig. 1, the battery protection board 4 is attached to the upper side of the mounting bracket 1, and the length of the battery protection board 4 is the sum of the length of the mounting bracket 1 and the thickness of the two cover plate assemblies 3, in other words, the overall length of the housing formed by the mounting bracket 1 and the two cover plate assemblies 3 after assembly is equal to the length of the battery protection board 4, so that the projection of the mounting bracket 1 in the horizontal plane and the projection of the battery cell connection piece 31 in the horizontal plane can be overlapped, and when the battery protection board 4 is formed with a jack penetrating along the thickness direction of the battery protection board itself, the pins 315 on the upper edge of the connection piece body 314 can be vertically inserted into the jack to realize the connection of the cover plate assemblies 3 and the battery protection board 4.
Alternatively, referring to fig. 1, the length of the pins 315 is greater than the thickness of the battery protection plate 4, so that after the pins 315 are inserted into the battery protection plate 4, they can be bent and attached to a side surface of the battery protection plate 4 facing away from the mounting bracket 1, so that the mounting stability of the battery protection plate 4 can be further improved.
It will be appreciated that the battery protection plate 4 is formed with insertion holes at both ends in the length direction of the mounting bracket 1 so as to be connected with the pins 315 on the two cell connection pieces 31 at both ends of the mounting bracket 1, thereby improving the stability of the mounting of the battery protection plate 4.
Alternatively, referring to fig. 2, projections of the pins 315 of the cell connection pieces 31 and the connection pins 322 of the insulating cover 32 in the horizontal reference plane are offset from each other, so that the connection of the cell connection pieces 31 to the battery protection plate 4 and the connection of the insulating cover 32 to the mounting bracket 1 are prevented from interfering with each other.
In a specific example, the cell connecting piece 31 may be a copper sheet or a copper alloy sheet, so that the cell connecting piece 31 has better conductivity, and meanwhile, has a certain elasticity, so that the elastic protrusion 311 on the cell connecting piece 31 can be ensured to be in stable contact with the cell 2.
Optionally, the insulating cover plate 32 is a plastic part, so that the insulating cover plate 32 has lighter weight, which is favorable for realizing the lightweight design of the battery 100, and moreover, as the battery 100 cover plate assembly 3 is only composed of the insulating cover plate 32 and the battery core connecting piece 31, compared with the scheme that the battery adopts a plurality of parts to form a feed-through assembly and a circuit connecting piece in the related art, the number of parts of the battery is reduced, the assembly process is simplified, the manpower requirement during production is reduced, and the cost can be saved to a greater extent.
