Abstract
Abstract An electrical connector assembly including a pair of mating shells (100, 200) having end faces (122, 224) on dielectric inserts (110, 210) and a coupling nut (300) rotatably mounted on first shell (100), coupling nut (300) including an elongated a generally U-shaped passageway (142, 146, 144) sized to receive a coupling pin (280) on second shell (200), the passageway forming an integral cantilevered latch spring (160) of the type having adjacent its deflectable end a detent (162) for captivating the pin (280), rotation of coupling nut (300) bringing end faces (122, 224) into abutment to stop axial advance but permit continued rotation to allow coupling pin (280) to advance along the passageway to deflect latch spring (162) downwardly and reach the detent (162) whereupon latch spring (162) springs forwardly to captivate coupling pin (280) therein.
