Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
171 words
In a cable fitting for connecting an insulated electric cable having a cylindrical surface, a cable being inserted into the fitting, the fitting having a fastening part bounding a space which is filled with a dielectric fluid medium, and a sealing member formed of elastic material for making a dielectric-fluid-tight seal between said part and said cylindrical surface, the improvement wherein the sealing member is a unitary element consisting of a cylindrical portion which is elastically fitted over said cylindrical surface, and a radially extending flange, said flange having an outer annular clamping portion having two sides and an intermediate portion between the clamping portion and the cylindrical portion, said fastening part is arranged so as to abut one side of said clamping portion only of the sealing member, and said fitting includes a clamping part arranged to abut said clamping portion only at the other side, and means for axially fastening said clamping part to said fastening part so as to exert clamping pressure therebetween on said annular clamping portion.
Claim 2
Dependent Claim
171 words

Claim 3
Dependent Claim
30 words
A cable fitting as claimed in claim 1 wherein the clamping portion of the flange is toroidally shaped, and the intermediate portion has lesser axial thickness than the clamping portion.
