Generally, embodiments of the invention can include a linear shaped charge (LSC) end cap coupling structure adapted for holding an initiator structure adapted to initiate a booster explosive material, the booster explosive material, and the LSC in abutting contact with each other. One embodiment includes a rubber body formed with cavities adapted to receive the LSC, booster, and initiator structure (e.g., detonation cord). One internal cavity can be formed with a plurality of flexible protrusions or fins which are oriented towards a center axis of the preferred embodiment of three cavities configured to impart an interference fit with the initiator structure. Methods related to the invention are also provided.

1. A coupling structure comprising: a body formed from an elastomeric material comprising a shaft end section and an opposing neck protrusion section, wherein said shaft end section and neck protrusion section are formed respectively with a first and second aperture that open into a first and second cavity section within said body, said first and second cavity sections open into each other, wherein said first cavity section is formed with a first interior cavity wall having a first distance between opposing sides of said first cavity section, wherein said second cavity section is formed with a second interior cavity wall having a second distance between opposing sides of said second cavity section, wherein the first distance is larger than the second distance;wherein said shaft end section is formed with a flexible interference fit adapted to receive and retain a linear shaped charge (LSC) up to a first force;wherein said second cavity section within said neck protrusion section is formed comprising a plurality of spaced apart protrusions or fins that extend a first distance away from said second cavity section wall towards a common center axis, wherein said plurality of spaced apart protrusions or fins are adapted or formed to displace, securely grip, and retain a initiator structure inserted into said second cavity through said neck protrusion up to a second force;wherein said neck protrusion section comprises a plurality of external stiffening sections adapted to increase structural rigidity of said neck protrusion formed on an exterior wall of said neck protrusion section and coupled to a portion of said shaft end section that extends away from said neck protrusion section. 2. A coupling structure as in claim 1, wherein said plurality of spaced apart protrusions or fins extend into said second cavity less than half of a distance defined by a radius from said common center axis of said second cavity to said second interior cavity section wall. 3. A coupling structure as in claim 1, wherein said second aperture into said second cavity is formed having an angled bevel surrounding said second aperture wherein said angled bevel is formed to facilitate insertion of said initiator structure. 4. A coupling structure as in claim 1, wherein said first cavity is adapted to receive an explosive sheet booster and hold said explosive sheet booster in contact with said LSC upon insertion of said LSC into said shaft end section, said coupling structure further formed to hold said initiator structure in contact with a user installed booster on an opposing side of said explosive sheet booster from said LSC. 5. A coupling structure as in claim 4, further comprising said LSC, said explosive sheet booster, said user installed booster, and said initiator structure. 6. An explosive assembly including a coupling structure comprising: a body formed from an elastomeric material comprising a shaft end section and an opposing neck protrusion section; wherein said shaft end section and opposing neck protrusion section are formed respectively with a first and second aperture that open into a first and second cavity section within said body, said first and second cavity sections open into each other, wherein said first cavity section is formed by a first interior cavity wall having a first distance between opposing sides of said first cavity section, wherein said second cavity section is formed by a second interior cavity wall having a second distance between opposing sides of said second cavity section, wherein the first distance is larger than the second distance;a linear shaped charge (LSC);wherein said shaft end section is formed with a flexible interference fit adapted to receive and retain the linear shaped charge up to a first force;wherein said second cavity section within said opposing neck protrusion section is formed comprising a plurality of spaced apart protrusions or fins that extend a third distance away from said second interior cavity wall, wherein said plurality of spaced apart protrusions or fins are adapted or formed to displace, securely grip; and retain a initiator structure inserted into said second cavity section through said opposing neck protrusion up to a second force;wherein said opposing neck protrusion section comprises a plurality of external stiffening sections adapted to increase structural rigidity of said opposing neck protrusion formed on an exterior wall of said opposing neck protrusion section and coupled to a portion of said shaft end section that extends away from said opposing neck protrusion section. 7. An explosive assembly as in claim 6, wherein said plurality of spaced apart protrusions or fins extend into said second cavity section less than half of a distance defined by a radius from a common center axis of said second cavity section to said second interior cavity section wall. 8. An explosive assembly as in claim 6, wherein said second aperture into said second cavity section is formed having an angled bevel surrounding said second aperture wherein said angled bevel is formed to facilitate insertion of said initiator structure. 9. An explosive assembly as in claim 6, wherein said first cavity section is adapted to receive a sheet booster explosive material and hold said sheet booster explosive material in contact with said LSC upon insertion of said LSC into said shaft end section, said explosive assembly further formed to hold said initiator structure in contact with a booster explosive material on an opposing side of said sheet booster explosive material from said LSC. 10. An explosive assembly as in claim 9, further comprising said sheet booster explosive material, said booster explosive material, and said initiator structure.
