Abstract
A device for interconnecting battery elements has at least one electrically conductive strip with at least one contact area for a battery element, and at least one permanent magnet, which magnet is associated with the contact area and configured to apply the contact area to a terminal of a battery element by magnetic interaction with the battery element. The contact area of the strip has a stamped relief in the strip, the stamped relief forming a receptacle for a magnet. The magnet is housed within the receptacle for a magnet. Also disclosed is a battery of accumulators provided with the interconnection device. It is applicable to batteries for supplying power to handheld power tools, in particular.
Claims17
A device for interconnecting battery elements comprising:
- at least one electrically conductive strip having at least one stamped relief with a substantially flat part located at a bottom portion of the at least one stamped relief, the bottom portion constituting at least one contact area of the at least one conductive strip, the at least one contact area being adapted to mechanically and directly contact a terminal of one of the battery elements, wherein the bottom portion presents a round hole that is centered in the substantially flat part and that is surrounded by an electric contact surface to ensure an annular distribution of a surface of contact between the at least one contact area and the terminal, wherein the at least one stamped relief of said at least one conductive strip also forms a side wall extending perpendicular to the substantially flat part, the side wall being adjacent to the at least one contact area and forming a magnet receptacle with the substantially flat part;
- a crimping armature made from a steel ring, thrilling a magnetic flux guide and in contact with and surrounding an external surface of the side wall of the at least one stamped relief;
- and
- at least one permanent magnet respectively cooperating with the at least one contact area, said at least one permanent magnet being adapted to be secured to the terminal of the battery element by magnetic interaction with the battery element, said at least one permanent magnet being seated in the magnet receptacle with the side wall being interposed between the crimping armature and the permanent magnet, said crimping armature holding said at least one permanent magnet in place via crimping of said at least one permanent magnet to the side wall.
