Abstract
This invention relates to an expansion device to permit the conductor to be extended beyond its normal operational length without breaking the electrical connection between the objects. In the preferred embodiment of the invention, a spring maintains the conductor at a predetermined length. The spring permits the conductor to be moved away from one of the objects for a predetermined distance without breaking the electrical connection between the objects. Preferably, the spring itself is conductive and connects two portions of the conductor which are relatively non-expandable. Alternatively, the spring in its relaxed state may merely maintain some slack in the conductor, the slack being taken up when the spring is compressed. In either embodiment, the spring tensioning mechanism may be contained entirely within one of the objects.
