Abstract

A hollow, cylindrically shaped, elastically deformable sealant member is disposed over external threads of a mounting unit, and subsequently a driver element having internal threads matable with the external threads is screwed onto the external threads, an elasticity and inside diameter of the sealant member being such so as to tightly adhere to at least one turn of the external threads and an outer surface of the driver element to provide an environmental seal between the internal and external threads.

Claims

1. A connector for connecting a first coaxial cable to a coaxial cable box, the coaxial cable box having a first threaded member for receiving the first coaxial cable, said first threaded member having external threads on an outer surface thereof, comprising:

a second threaded member connected to said first coaxial cable and having internal threads therein matable with said external threads of said first threaded member of said coaxial cable box;

a hollow, cylindrically shaped, elastically deformed sealant member disposed on some of said external threads and on an external surface of said second threaded member;

said sealant member having an unstretched substantially uniform inside diameter which is less than an outside diameter of both said first and second threaded members, said sealant member having an elasticity such that part of an inner surface thereof substantially fills and tightly contacts at least one groove turn of said external threads on which said sealant member is disposed and such that another part of said internal surface of said sealant member tightly contacts an external nut surface of said second threaded member.

2. The connector as claimed in claim 1, said coaxial cable being a CATV coaxial drop wire, said box being a CATV coaxial cable drop wire box.

3. A method for sealing a connection between a coaxial cable and a mounting unit therefore, comprising the steps of:

disposing a hollow, cylindrically shaped, elastically deformable sealant member over external threads of said mounting unit; and

screwing a threaded member having internal threads matable with said external threads over said external threads of said mounting unit, said sealant member having an unstretched substantially uniform inside diameter which is less than an outside diameter of both the external threads and an external nut surface of said threaded member, an elasticity of said sealant member being such that said sealant member tightly adheres to at least one turn of said external threads and to said external nut surface of said threaded member.
