ACCUMULATOR AND CONNECTION DEVICE Russian patent published in 2020 - IPC H01M2/10 H01M2/30 H01M10/42 

FIELD: electrical equipment.

SUBSTANCE: invention relates to a battery and a connection device to which such a battery is connected. According to the invention, the battery comprises: a housing, inside which the battery cell is located; and terminal section, having in terminal connector, connected to electrode terminal of connection device. In housing is functional groove, longitudinal direction of which coincides with direction of connection between terminal of connector and electrode terminal, and which has a predetermined function, and in the composition of this functional groove there are several functional sections continuously connected to each other, the lengths of which differ from each other. In such design between several functional sections there are no sections, which would isolate these several functional sections, having different lengths, from each other, owing to which size of functional groove in direction, in which functional sections continuously change one into another, becomes the total size of these several functional sections.

EFFECT: technical result is reduction of dimensions while maintaining high functionality.
