Abstract
Abstract An improved terminal connection arrangement for an electrical component is provided in which a core means extends throughout the length of the electrical component and has terminal members at each end surface. The terminal members have an attachment portion. These may be male or female threads. Each of the malethreaded portions has a lead-receiving aperture therethrough. A wirelike lead means is inserted in each of the lead-receiving apertures and a deformable washer such as a lead or soft copper washer is placed over the threaded end portion of the terminal member and a rigid washer is placed adjacent the deformable washer. A nut threadingly engages the threaded portion and clamps the rigid washer against the deformable washer thereby deforming the deformable washer and pressing the lead means tightly against the end surface of the electrical component to make electrical contact therewith to provide circuit continuity through the component. No soldering, welding, dipping or spraying is required and therefore a heatless terminal connection is achieved. In the female-threaded embodiment, any desired threaded insert may be installed.
