Abstract
Abstract A crimpable barrel, usually with a serrated, burled or other type irregular shaped inner surface is crimped around a piece of elastomeric material after a fine wire has been layed in between the elastomeric material and the inner surface of the barrel. This type crimp connection will break away the varnish or shellac type insulation on the fine wire and make good electrical connection with the barrel, without breaking or appreciably damaging the structural strength of the wire.
