Abstract

A device for coupling a battery to an electric appliance including two magnetic plates, one of the magnetic plates having an opening for engagement with a center electrode of the battery, the other magnetic plate attractable to the case electrode of the battery, and a wire for electrically coupling the magnetic plates to the electric appliance in order to energize the electric appliance.

Claims

1. A device for coupling at least one battery to an electric appliance comprising a first magnetic plate having an opening formed therein for engagement with a center electrode of said battery, means for electrically coupling said first magnetic plate to said electric appliance, a second magnetic plate attractable to an electrode of said battery, and means for electrically coupling said second magnetic plate to said electric appliance in order to energize said electric appliance, said means for electrically coupling said magnetic plates to said electric appliance including electric wires, each having a first end connected to said electric appliance and having a second end connected to a respective said magnetic plate by a screw.

2. A device for coupling at least one battery to an electric appliance comprising a first magnetic plate having an opening formed therein for engagement with a center electrode of said battery, means for electrically coupling said first magnetic plate to said electric appliance, a second magnetic plate attractable to an electrode of said battery, and means for electrically coupling said second magnetic plate to said electric appliance in order to energize said electric appliance, said center electrode of said battery having a protruded length slightly less than the thickness of said first magnetic plate.

3. A device for coupling at least one battery to an electric appliance comprising a first magnetic plate having an opening formed therein for engagement with a center electrode of said battery, means for electrically coupling said first magnetic plate to said electric appliance, a second magnetic plate attractable to an electrode of said battery, and means for electrically coupling said second magnetic plate to said electric appliance in order to energize said electric appliance, said means for electrically coupling said magnetic plates to said electric appliance including electric wires, each having a first end connected to said electric appliance and having a second end connected to a respective said magnetic plate by a clip.
