Abstract:
1. A cable release mechanism for retaining the adjacent ends of two cables each having a proximal end and a distal end, and releasing the two cables upon receiving an electrical current of a sufficient magnitude from a remote source through external electrical connectors, comprising: a. a casing having a longitudinal chamber for housing two oppositely disposed non-explosive actuators (NEAs), and a transverse center bore for housing a jaw and ramp assembly for retaining and releasing said adjacent ends of said two cables; b. each said NEA having two spool halves bound by a wrap wire for resisting an outward movement of a spring biased plunger, a link wire for maintaining tension of said wrap wire, and electrical terminals connected to the link wire and adapted for connection with said external electrical connectors; c. said jaw and ramp assembly having two longitudinally oppositely arranged jaw members each attached to a proximal end of said plunger of a respective one of said two NEAs, and two transversely oppositely disposed ramp members each holding a respective one of said proximal ends of said two cables; and d. each said jaw member having two inward facing recesses, and each said ramp member having two outward facing flanges, such that the engagement of said flanges of said ramp members with said recesses of said jaw members retains said proximal ends of said two cables together within said transverse center bore of said casing; e. whereby when said electrical current is applied on said link-wire of any one or both of said NEAs, said link-wire will break, causing said wrap-wire to be loosened, which allows said spool halves to separate, which permits said outward movement of said plunger and said jaw member attached thereto, which in turn allows said adjacent ends of said two cables to be released from said casing.
