Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
120 words
Screw-type fitting for holding an elongated member, comprising a threaded socket, a cap nut and at least one elastomeric clamping ring which will be pressed against an outer surface of the elongated member by screwing the cap nut onto the threaded socket, wherein edged grains of hard, electrically insulating material are fixedly arranged on first portions of the inner surface of the clamping ring which will be pressed against the outer surface of the elongated member when the cap nut is screwed onto the threaded socket, said grains digging into the outer surface in a positively connected manner when pressed against the outer surface, second portions of the inner surface of the clamping ring being free of said edged grains.
Claim 2
Dependent Claim
120 words
Screw-type fitting for holding an elongated member, comprising a threaded socket, a cap nut and at least one elastomeric clamping ring which will be pressed against an outer surface of the elongated member by screwing the cap nut onto the threaded socket, wherein edged grains of hard, electrically insulating material are fixedly arranged on first portions of the inner surface of the clamping ring which will be pressed against the outer surface of the elongated member when the cap nut is screwed onto the threaded socket, said grains digging into the outer surface in a positively connected manner when pressed against the outer surface, second portions of the inner surface of the clamping ring being free of said edged grains.
