The elastic device comprises elastomeric material, such as silicone rubber, and has electrical conductive, compressible wires formed of a metal, such as monel, embedded in the silicone. The elastic device is particularly suited to provide electrical connections between an interface that is brought together by a connector and which is separable in response to an impulse that may be created by an explosion produced by a pyrotechnic device. ## Claims ### Claim 1 A separable connector that provides solderless electrical connections between first and second electrical equipments, said separable connector comprising: (a) first and second plates respectively carrying electrical terminals of said first and second electrical equipments; (b) means for holding and compressing together the first and second plates and having a first cutout with predetermined dimensions, said holding and compressing means further having a means responsive to an impulse for releasing said holding and compressing of said first and second plates; and (c) a device inserted into said cutout and comprising elastic material and having a plurality of compressible conductive wires that are embedded in said elastic material, said conductive wires being spaced apart from each by a predetermined distance of about 0.035 inches and said wires are of a monel metal and include about 750 to about 900 wires per square inch, said conductive wires providing a plurality of electrical paths each having an electrical resistance of less than 5 milliohms between said terminals of said first and second electrical equipments when said first and second plates are being held and compressed together. ### Claim 2 (depends on 1) A separable connector according to claim 1, wherein said elastic material is silicone rubber ### Claim 3 (depends on 2) A separable connector according to claim 2, wherein said silicone rubber provides a gas seal when said first and second plates are being held and compressed together. ### Claim 4 A separable connector that provides solderless electrical connections between first and second electrical equipments, said separable connector comprising: a) first and second plates respectively carrying the electrical terminals of said first and second equipments; b) means for holding and compressing together the first and second plates and having first cutout with a predetermined dimensions and a second cut-out with predetermined dimensions; c) impulse means lodged in said second cutout and responsive to an input from a pyrotechnic device; d) a device inserted into said first cutout comprising elastomeric material and having a plurality of compressible conductive wires that are embedded in said elastomeric material and that are spaced apart from each other by a predetermined distance, said compressible conductive wires providing the electrical paths between said terminals of said first and second electrical equipments when said first and second plates are held and compressed together, each of said electrical paths having an electrical resistance of less than 5 milliohms. ### Claim 5 (depends on 1) A separable connector according to claim 1, wherein said impulse is created by an explosion produced by a pyrotechnic device. ### Claim 6 A separable connector that provides solderless electrical connections between first and second electrical equipments, said separable connector comprising: a) first and second plates respectively carrying electrical terminals of said first and second electrical equipments, said electrical terminals being in the form of concentric rings that are disposed about a respective central region; b) means for holding and compressing together the first and second plates so that concentric rings of said first plate are in alignment with said concentric rings of said second plate, said means for holding and compressing having a first cutout with predetermined dimensions and a second cutoff having predetermined dimensions and located in correspondence with said respective central regions of said first and second plates; c) means responsive to an impulse and being inserted into said second cutout of said means for holding and compressing; d) an elastic device inserted into said first cutout and having a central region removed therefrom to provide a space that is somewhat greater than and in alignment with said second cutout, said elastic device comprising an elastic material and having a plurality of compressible conductive wires that are embedded in said elastic material and that are spaced apart from each by a predetermined distance, said conductive wires providing the electrical path between said concentric terminals of said first and second equipments when said first and second plates are held and compressed together. ### Claim 7 (depends on 6) A separable connector according to claim 6, wherein said elastic material is silicone rubber and said compressible conductive wires are of a mortal metal. ### Claim 8 (depends on 6) A separable connector according to claim 6, wherein said silicone rubber provides a gas seal for said concentric terminals when said first and second plates are held and compressed together. ### Claim 9 (depends on 7) A separable connector according to claim 7, wherein said predetermined distance of said spaced apart mortal wires is about 0.035, and wherein about 750-900 monel wires per square inch are embedded in said elastic material, and wherein each of said electrical paths has an electrical resistance of less than 5 milliohms.
