Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
A coupling device for selectively preventing and enabling access to a coaxial plug comprising: a housing, a coupling cap within said housing, means for retaining said cap within said housing, said cap and housing being rotatable with respect to each other about a common axis when said cap is so retained within said housing, means for engaging said cap with said plug, said cap being formed with spaced-apart tool-engagement means, and said housing being formed with spaced-apart slot means that can be aligned with said tool-engagement means in such a manner that spaced-apart fingers which are formed on a rigid tool and respectively capable of passing through said slot means are respectively engageable with said tool-engagement means for selectively engaging said cap with and disengaging said cap from said plug, and further comprising a deformable baffle between said slot means and said tool-engagement means.
Claim 2
Dependent Claim
144 words
A coupling device for selectively preventing and enabling access to a coaxial plug comprising: a housing, a coupling cap within said housing, means for retaining said cap within said housing, said cap and housing being rotatable with respect to each other about a common axis when said cap is so retained within said housing, means for engaging said cap with said plug, said cap being formed with spaced-apart tool-engagement means, and said housing being formed with spaced-apart slot means that can be aligned with said tool-engagement means in such a manner that spaced-apart fingers which are formed on a rigid tool and respectively capable of passing through said slot means are respectively engageable with said tool-engagement means for selectively engaging said cap with and disengaging said cap from said plug, and further comprising a deformable baffle between said slot means and said tool-engagement means.
Claim 3
Dependent Claim
55 words
A device as described in claim 1 wherein said cap comprises a head and a body extending therefrom, said head being formed with a well, said body being formed with a central bore that communicates with said well, and said means for engaging said cap with said plug comprising thread means formed in said well.
Claim 4
Dependent Claim
36 words
A device as described in claim 1 wherein said retaining means comprises a circumferential channel formed near one end of the inner surface of said housing, and a relatively circular spring clip engaged in the channel.
Claim 5
Dependent Claim
30 words
A device as described in claim 1 wherein the plug terminates a TV cable, further comprising a matching impedance resistor mounted within said cap for electrical connection to said cable.
Claim 6
Dependent Claim
26 words
A device as described in claim 1 wherein the axial length of the cap is less than the distance between said retaining means and the baffle.
Claim 7
Dependent Claim
44 words
A device as described in claim 1 wherein said cap is coaxial with said housing and comprises a cylindrical head and a body extending from the head, at least a portion of said head adjacent to said body being radially wider than said body.
Claim 8
Dependent Claim
20 words
A device as described in claim 6 wherein said tool-engagement means comprises at least two notches formed in said head.
