Abstract
A modular electrical connector assembly consisting of a plurality of components which can be assembled in a number of different configurations is disclosed. Each connector consists of an outer body (100, 200) and an inner body (300, 400). The inner and outer bodies are separately and independently keyed and each mates with a corresponding inner or outer body in only one configuration. The inner body is keyed by providing distinct cross-sections for intermating posts (310) and cavities (410). The outer bodies (100, 200) are latched together by a plurality of collects (202) on one connector (200) which are held in engagement with a cylindrical ridge (130) on the other connector by a spring loaded shiftable sleeve (150). Keys (142) on one connector are received in keyslots (212), between adjacent collets (202) on the other connector. Conductors (30) in distinct and corresponding ordered arrays can be interconnected and the circuit patterns need not be changed in order to provide for connector modulatity.
