Abstract: An electrical connector for ribbon cable terminals has first and second longitudinally sets of conductor pins embedded in a block of insulating material. Each pin has a first end portion and a second end portion, the axes of which are in spaced parallel relationship, and a bent intermediate portion. On each side of the block a row of first end portions and a parallel spaced row of second end portions are defined. The intermediate portions on the pins of one set respectively cross the intermediate portions of the other set in the block without making contact. The connector is adapted to interconnect the terminals for diagnostic purposes, including Alpha continuity checks, as well as permitting connection of series or cascades of such terminals without the need for modifying cable terminations.
