Abstract
Abstract An adapter is described with which cells of conventional size but of voltage approximately double that of conventional cells may be directly substituted in devices such as flashlights and the like. The adapter is formed of at least a pair of conductive elements which are shaped and sized to interconnect like cell electrodes for parallel connection of the cells. Several adapter embodiments are described with one for parallel connection of end to end located cells in a flashlight and the other adapter embodiment to parallel connect cells arranged in side by side relationship.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
217 words
An adapter for parallel electrical connection of high electrical voltage cells having positive and negative electrodes at opposite front and rear located ends and being oriented in parallel adjacent relationship with electrodes of opposite polarity at each end of the combinded parallel arranged cells, comprising: a thin flexible insulating sleeve for housing the cells, the sleeve further including first and second axial ends adapted to be aligned with the ends of the combined parallel arranged cells, the first end being closed and the second end being formed witn an opening, and being formed with a slot substantially extending axially along a first side of the sleeve, the slot adapted to form an opening through which the cells are inserted into the sleeve; and first and second electrically separated conductive elements located within the sleeve, the elements each including a segment on each end of the elements for making contact with an electrode of a cell, the elements extending in opposite diagonal directions within the sleeve from the first to the second ends of the sleeve such that the first element connects the positive electrodes of the cells and the second element connects the negative electrodes of the cells, the elements being generally adjacent the inner surface of a side of the sleeve opposite to the first side.
