Abstract
Abstract A jack strip assembly is provided comprising an outer casing and an inner housing assembly. The inner housing includes a rear wall and a pair of side walls secured to the rear wall wherein the side walls are provided with a plurality of vertically spaced and horizontally aligned slots. Modular jack strips having a plurality of jacks and a pair of side shoulders are horizontally disposed within the inner housing assembly by engagement of the shoulders within the slots. Tuning fork contact assemblies having wire wrap terminals are positionally secured to the rear wall and adapted to removably receive contact blades or fingers of the individual jack appearances within each of the jack strips. The jack strip assemblies are provided with a longitudinal bore disposed in coaxial alignment with a keyway or slot provided in the rear wall. Extending through the longitudinal bore is a bayonet-type fastener having a slotted head and pairs of spaced flanges at the distal end portion thereof. When the jack strip is inserted within the housing assembly, it is removably secured with respect thereto by a predetermined amount of forward longitudinal movement and a quarter-turn rotation of the fastener. The rotational movement of the fastener causes the most distally positioned flanges to abuttingly engage the rear surface of the rear wall and the innermost flanges to abuttingly engage the inner surface of the jack strip assembly, thereby securing said jack strip assembly with respect to said inner housing assembly.
