Abstract
An electrical apparatus houses batteries mounted on a printed circuit board (PCB) via conducting tabs with cylindrical insertion sections. The cylindrical insertion sections fit into circular holes in the PCB or into cylindrical sockets soldered into PCB holes. Battery attachment can either be permanent by soldering tabs into the holes or removable by tab insertion into sockets. Removable attachment allows easy battery recovery for recycling. Utilizing the elasticity of sheet metal and cylindrical shaped tabs provides more secure battery attachment resulting in good shock and vibration resistance, and contact over a cylindrical surface insures good electrical connection.

An electrical apparatus for attaching a battery to a printed circuit board in a removable fashion, comprising:
- a sheet metal socket connector which has a cylindrical connecting section to connect in a removable fashion a sheet metal conducting tab fixed to a battery electrode, and which itself is secured to the printed circuit board to attach the battery to the printed circuit board in a removable fashion;
- a conducting tab provided with a cylindrical insertion section which inserts into the cylindrical connecting section of the socket connector and has a pressure contact section which is slit vertically with opposing sides that open flexibly outward in the radial direction, and wherein the pressure contact section is curved to almost conform to the inner surface of the cylindrical connecting section to make surface-to-surface electrical contact with an inner surface of the cylindrical connecting section;
- wherein the cylindrical connecting section of the socket connector is formed as a metal pipe;
- and
- wherein the socket connector is secured by solder to a conducting run on the upper surface of the printed circuit board.
