Patent ID: 7431619

Claim:
A detachable coupling for selectively attaching first and second cables of a remote inspection device comprising: a first casing having a first longitudinal axis and a passage extending between opposing ends of said first casing along said first longitudinal axis, said passage having a first portion adjacent to one end of said first casing defining a first ferrule socket and a second portion adjacent to the opposite end of said first casing defining a first connector socket; a first ferrule component comprised of an electrical insulating material and encasing an end of the first cable, wherein said first ferrule component is inserted into said first ferrule socket, thereby creating a fluid seal between said first casing and the first cable and electrically isolating said first casing from the first cable; a first electrical connector electrically connected to wires of the first cable, wherein said first electrical connector is inserted into said first connector socket; a second casing having a second longitudinal axis and a second passage extending between opposing ends of said second casing along said second longitudinal axis, said second passage having a first portion adjacent to one end of said second casing defining a second ferrule socket and a second portion adjacent to the opposite end of said second casing defining a second connector socket; a second ferrule component comprised of an electrical insulating material and encasing an end of the second cable, wherein said second ferrule component is inserted into said second ferrule socket, thereby creating a fluid seal between said second casing and the second cable and electrically isolating said second casing from the second cable; and a second electrical connector electrically connected to wires of the second cable, wherein said second electrical connector is inserted into said second connector socket, wherein said first casing further includes a first tapered mating surface oblique to said first longitudinal axis and said second casing further includes a second tapered mating surface complementary to said first tapered mating surface, said first tapered mating surface engaging said second tapered mating surface when said first casing is coupled to said second casing to thereby inhibit relative movement between said first longitudinal axis and said second longitudinal axis.
