Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
130 words
A grounding connector for grounding a shield of a cable, said grounding connector consisting of a backshell formed with a tapered inner periphery; a cap nut; and a ring disposed between said cap nut and the tapered periphery of said backshell with the shield being held between said tapered inner periphery and said ring, said ring having means for regulating the distance between said ring and said cap nut when said cap nut is positioned against said regulating means; and wherein said ring is resilient, is formed with a single slit, and is positioned to cause said shield to contact said backshell tapered inner periphery; and wherein said regulating means comprises at least three circumferentially spaced protrusions formed unitarily with said ring and extending toward and engaging said cap nut.
Claim 2
Dependent Claim
130 words
A grounding connector for grounding a shield of a cable, said grounding connector consisting of a backshell formed with a tapered inner periphery; a cap nut; and a ring disposed between said cap nut and the tapered periphery of said backshell with the shield being held between said tapered inner periphery and said ring, said ring having means for regulating the distance between said ring and said cap nut when said cap nut is positioned against said regulating means; and wherein said ring is resilient, is formed with a single slit, and is positioned to cause said shield to contact said backshell tapered inner periphery; and wherein said regulating means comprises at least three circumferentially spaced protrusions formed unitarily with said ring and extending toward and engaging said cap nut.
Claim 3
Dependent Claim
16 words
The device of claim 1, wherein said cap nut comprises a collar and a stepped portion.
Claim 4
Dependent Claim
