Abstract
Abstract An interposing connector for interconnecting a pattern of conductive areas of opposing spaced apart surfaces. The connector includes a housing having one or more openings therethrough. A plurality of canted coil springs are positioned within the housing so that outer coil portions are exposed to engage the conductive areas of the opposing surfaces to thereby establish the electrical interconnection. The canted coil springs are secured to the housing by retaining means, such as a retainer strip extending through the springs and secured to the housing. The springs may also be secured by heat staking or laser welding a portion thereof to the housing. The canted coil springs have a relatively constant compliance over a range of radial deflection. The springs also produce contact wipe over the conductive areas and establish redundant contact points therewith.
