A high-load capability non-explosive cable release mechanism for retaining the adjacent ends of two cables and releasing them upon receiving a signal from a remote source. The cable release mechanism has a casing for housing two non-explosive actuators (NEAs), which also has a center bore for housing a jaw and ramp assembly. Each NEA is connected to the jaw and ramp assembly for independently operating the jaw and ramp assembly to retain or release the proximal ends of the two cables. Upon receiving the signal by any one or both of the NEAs, the jaw and ramp assembly will release the adjacent ends of the two cables from the casing.

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; andd. 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.2. The cable release mechanism in accordance with claim 1, wherein said outward facing flanges of each said ramp member are wedge-shaped.3. 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 signal from a remote source through external electrical connectors, comprising:a. a casing having a chamber for housing two non-explosive actuators (NEAs), and a center bore which intersects the chamber for housing a jaw and ramp assembly for retaining and releasing said adjacent ends of said two cables;b. each said NEA having an outwardly movable plunger, an internal assembly that permits said plunger to move outwardly upon receiving of said electrical signal;c. said jaw and ramp assembly having two oppositely arranged jaw members each attached to a proximal end of said plunger of a respective one of said two NEAs, and two transversely disposed ramp members each holding a respective one of said proximal ends of said two cables; andd. said jaw members engaging and holding said ramp members in place to retain said proximal ends of said two cables together within said center bore of said casing;e. whereby upon receiving of said electrical signal by any one or both of said NEAs, said plunger of such one or both NEAs will move outwardly with said jaw member attached thereto, which allows said adjacent ends of said two cables to be released from said casing.4. The cable release mechanism in accordance with claim 3, wherein said two NEAs are oppositely disposed in said chamber of said casing.5. The cable release mechanism in accordance with claim 3, wherein said plunger of each said NEA is biased by a spring which urges said plunger to move outwardly.6. The cable release mechanism in accordance with claim 3, wherein each said NEA has two spool halves bound by a wrap wire for resisting an outward movement of said plunger.7. The cable release mechanism in accordance with claim 6, wherein each said NEA has a link wire for maintaining tension of said wrap wire to bind said two spool halves together.8. The cable release mechanism in accordance with claim 7, wherein each said NEA has electrical terminals connected to said link wire and adapted for connection with said external electrical connectors. 9. The cable release mechanism in accordance with claim 3, wherein each said jaw member has two inward facing recesses, and each said ramp member having two outward facing flanges for engagement with said recesses of said jaw members.10. The cable release mechanism in accordance with claim 9, wherein said outward facing flanges of each said ramp member are wedge-shaped.11. 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 a signal from a remote source, comprising:a. a casing having a chamber for housing two non-explosive actuators (NEAs) and having a center bore for housing a jaw and ramp assembly;b. each said NEA connected to said jaw and ramp assembly for independently operating said jaw and ramp assembly to retain or release said proximal ends of said two cables; andc. each said NEA has a plunger biased by a spring which urges the plunger to move outwardly;d. whereby upon receiving said signal by any one or both of said NEAs, said jaw and ramp assembly will release said adjacent ends of said two cables from said casing.12. The cable release mechanism in accordance with claim 11, wherein said two NEAs are oppositely disposed in said chamber of said casing.13. The cable release mechanism in accordance with claim 11, wherein each said NEA has two spool halves bound by a wrap wire for resisting an outward movement of said plunger.14. The cable release mechanism in accordance with claim 13, wherein each said NEA has a link wire for maintaining tension of said wrap wire.15. The cable release mechanism in accordance with claim 14, wherein each said NEA has electrical terminals connected to said link wire and adapted for connection to said remote source.16. The cable release mechanism in accordance with claim 11, wherein said jaw and ramp assembly has two oppositely arranged jaw members each attached to a proximal end of an outwardly movable plunger of a respective one of said two NEAs.17. The cable release mechanism in accordance with claim 16, wherein said jaw and ramp assembly has two transversely disposed ramp members each holding a respective one of said proximal ends of said two cables. 18. The cable release mechanism in accordance with claim 17, wherein each said jaw member having two inward facing recesses, and each said ramp member having two outward facing flanges for engagement with said recesses of said jaw members.19. The cable release mechanism in accordance with claim 18, wherein said outward facing flanges of each said ramp member are wedge-shaped.
