Abstract: Described is a two-part housing for a battery cell having circuitry separate from the main body of the cell. Finger joints, blind dado joints, and edge joints with rabbeted edges are disposed in the mating region between the two halves of the housing. An insulating and alignment wall is integral with one half of the housing, and fits in the channel between the main body of the cell and the circuitry. The housing is dimensionally stable, provides mechanical protection for the delicate cell circuitry, and the two halves of the housing may be secured using only a label wrap.

Abstract: Described is an integral electrical contact block and printed circuit board for an electrical device. The electrical contacts arch over components on the printed circuit board and are secured to the printed circuit board at either end of the arch. A second arch is above the lower arch, secured to the lower arch at one end, forming a structure with an open mouth. This open mouth can capture a plastic housing. The contact provides protection for components beneath it, provides for efficient use of space in an electrical device, and the mouth of the contact absorbs shock that otherwise might be transmitted directly to solder joints on the printed circuit board.
