Lock device for use with coaxial cable connection

A lock device for use with a coaxial cable connection having a female coaxial cable connector part attached to one end of a coaxial cable and a male coaxial cable connector part mounted to and extending from a device, comprising:

• (a) an inner annular member including
• (i) a first end portion having internal threads to screw said inner member onto the male coaxial cable connector part,
• (ii) a second end portion opposite said first end portion having a central bore extending-partially into said inner member, said bore being of a diameter and of a depth such that the female coaxial cable connector part is disposed within said bore and connected with the male coaxial cable connector part after said inner member is substantially screwed onto the male coaxial cable connector part, and
• (iii) an annular flange integrally formed on and protruding radially outward from an outside of an edge of said inner member;
• and
• (b) an outer annular sleeve having a central passageway extending through said outer sleeve, said outer sleeve including
• (i) a first end portion defining a first portion of said central passageway having a diameter greater than a diameter of said inner member but less than a diameter of said flange;
• (ii) a second end portion opposite said first end portion defining a second portion of said central passageway having a diameter less than said inner member but great enough to allow insertion of the coaxial cable terminated with the female coaxial cable connector part through said central passageway, and
• (iii) an intermediate portion between said first and second end portions defining a middle portion of said central passageway and having annular projection means for engaging said flange of said inner member at any selected one of a plurality of successive positions to thereby lock said outer sleeve on said inner member and prevent said outer sleeve from being slid back along the coaxial cable away from the male coaxial cable connector part;
• (c) said outer sleeve having a length such that with said flange engaged with said annular projection means in any selected one of said plurality of successive positions said outer sleeve substantially covers entirely said inner member and the coaxial cable connection thereby preventing access to the coaxial cable connection;
• (d) said annular projection means of said intermediate portion of said outer sleeve being a series of annular notches formed in an axially-spaced relationship to one another on said intermediate portion of said outer sleeve along said middle portion of said central passageway, said notches being engageable successively with said flange thereby locking said outer sleeve on said inner member and preventing said sleeve from being slid back along the coaxial cable.

In combination with a lock device, a coaxial cable connection having a male coaxial cable connector part mounted to and extending from a device and a female coaxial cable connector part complementary to and engagable with said male coaxial cable connector part and attached to one end of a coaxial cable, said lock device comprising:

• (a) an inner annular member including
• (i) a first end portion having internal threads, said inner member being screwed onto said male coaxial cable connector part,
• (ii) a second end portion opposite said first end portion having a central bore extending partially into said inner member, said bore being of a diameter and of a length such that said female coaxial cable connector part is disposed within said bore and connected with said male coaxial cable connector part after said inner member is substantially screwed onto said male coaxial cable connector part, and
• (iii) an annular flange integrally formed on and protruding radially outward from an outside of an edge of said inner member;
• and
• (b) an outer annular sleeve having a central passageway extending through said outer sleeve, said outer sleeve including
• (i) a first end portion defining a first portion of said central passageway having a diameter greater than a diameter of said inner member but less than a diameter of said flange;
• (ii) a second end portion opposite said first end portion defining a second portion of said central passageway having a diameter less than said inner member but great enough to allow insertion of the coaxial cable terminated with said female coaxial cable connector part through said central passageway, and
• (iii) an intermediate portion between said first and second end portions defining a middle portion of said central passageway and having annular projection means for engaging said flange to thereby lock said outer sleeve on said inner member and prevent said outer sleeve from being slid back along the coaxial cable away from said male coaxial cable connector part;
• (c) said outer sleeve having a length such that with said flange engaged with said annular projection means, said outer sleeve substantially covers entirely said inner member and said coaxial cable connection thereby preventing access to said coaxial cable connection.
