ABSTRACT:
An electrical fitting to be connected to an end of a cable, including an automatic disconnect mechanism which separates the electrical fitting from a mating electrical fitting responsive to a pull on the cable, the electrical fitting comprising at least one thrust member mounted for axial movement in ejection and retraction strokes between retracted and projecting positions and a trigger system which causes a pull on the cable of greater than a predetermined force to release the thrust members from the retracted position, the thrust members being moved axially in the ejection stroke to the projecting position by a resilient member after release to engage a fixed element associated with a mating fitting and cause the casing and the electrical contact elements therein to be moved by reaction and separated from contact elements of the mating fitting.
