Abstract: This specialized fiber optic jumper cable includes a composite cable with a glass fiber light guide for single or multi transmission mode, standard fiber optic connectors, electrically powered light emitting devices at the fiber optic connectors, and a pair of electrical conductors embedded in the cable, with one or more electrical power connectors for selectively applying an external electrical power source to the light emitting devices. One embodiment has a fiber optic connector at each end of the jumper. An LED and an electric power connector suitable for plug-in connection of a power pack are affixed to the cable adjacent each end such that both LEDs are lighted whenever power is applied to either of the electrical connectors. The attendant illumination of the LEDs provides an indication that the tracer system is activated and functioning properly and readily indicates where both ends of the same jumper cable are located.

Abstract: A micro-miniature electrical contact comprises a first contact portion having spaced cantilever contact leaves with distal ends adapted to mutually engage, together with outwardly bowed control longitudinal portions. When received in a mating socket the leaves are resiliently urged inwardly to effect desired receptacle engagement and electrical connection.In a preferred embodiment, the contact is formed by deep drawing a seamless, integral, generally cylindrical member in which a contact portion with leaves integrally joined at their distal ends is integrally formed with a receptacle portion adapted to engage an electrical conductor. Because of their construction, the provided contacts are adapted for repeated use without loss of resiliency.
