ABSTRACT:
A lamp capsule with lug connectors, having a lamp bulb, a holder, and a lug is disclosed. The lamp capsule lead extends through the holder passage to fit closely with the lug foot. The lug foot is then rotary swaged to the lamp lead. The swaging mechanically and electrically seals the lead and the lug. An interference coupling is exactly formed along the lead by the swaging, so the lead and lug are precisely located and cannot move with reference to one another. The lug and lead are then tightly held and located with reference to the holder. The mechanical interference fit also forms an electrical connection that cannot separate like a cold weld. The swaging may additionally remove any excess exterior extension of the lead. As a result, the lug is quickly, accurately, and permanently coupled to the lamp lead, and holder preventing subsequent loosening or displacement that may effect lamp positioning or connection durability.
