FIELD: electricity.
SUBSTANCE: present invention relates to accumulator power supplies, where the joint between the top part and the bottom part of the cover is made using ultrasonic welding in contact areas between their top and bottom ends. A film-type tag is fixed on the outer surfaces of the parts of the cover which are joined together. The cover is open on the upper surface of its top part and the lower surface on its bottom part. The overall height of the top and bottom parts of the cover joined together is equal to the height of the body of the accumulator, so that, the cover can be directly fastened to the tag without dropping on the height of the cover.
EFFECT: reduced thickness of the accumulator power supply and increased resistance to external impacts due stronger joints between parts of the cover.
