Sheath for protecting electric junction between a multipole cable and a plurality of independent conductors

Claim 1

A one-piece tubular sheath of stretchable and resilient insulating material for enclosing in a sealed manner the electrical interconnections between the conductors of a multiconductor cable having a plurality of conductors enclosed in a common jacket and a plurality of insulated independent conductors, said connections comprising a plurality of conductive sleeves corresponding in number to the number of interconnected conductors, each sleeve interconnecting one of said conductors of said multiconductor cable with one of said independent conductors and said sleeves extending generally parallel to each other, said tubular sheath comprising: a hollow central portion for surrounding a plurality of side-by-side, conductive interconnecting sleeves for interconnecting the conductors of a cable with a jacket around the latter conductors with a plurality of independent conductors and which has an open end at one end of said central portion for receiving said jacket with the wall of said open end in sealing engagement with said jacket, said open end being resiliently extendable to permit the passage of said sleeves; and an abutment wall at the opposite end of said central portion and extending transversely to the axis of said tubular sheath, said abutment wall having a plurality of openings therethrough equal in number to the number of said independent conductors for the passage of said independent conductors therethrough with the walls of said openings in sealing engagement with said independent conductors and said abutment wall with a portion of said central portion adjacent to said abutment wall defining a plurality of separately spaced peripherally closed cavities aligned with said openings and extending from a portion of said abutment wall toward said open end for receiving at least the end portions of said sleeves with the walls of each of said cavities respectively around an end portion of one of said sleeves and the ends of said cavities nearest said open end being spaced from said open end in the direction of said opposite end.
