Abstract
Abstract The present invention is directed to an end member for a cable sleeve, which end member is sub-divided into at least three segments, with each of the segments having a planar surface coacting with adjacent segments to form a parting plane on which cables are inserted. Each of the segments carry pressure plates which are urged toward each other to grip any cable being inserted therein to firmly anchor the cable in the end member of the cable sleeve.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
193 words
In an end member for sealing an end of a longitudinally divided cable fitting, said end member being composed of a plastic material and having adaptable cable entry openings which are formed in a parting plane of the member and which are cut, when desired, said end member having integrated clamping means for gripping the inserted cables, the improvements comprising said end member being divided in a transverse direction into two outer segments and a middle segment, with each segment having a planar surface cooperating with an adjacent segment to form a parting plane therebetween, reinforcing connecting elements being arranged to extend between the segments across the parting plane between two adjacent segments, each of the parting planes having gripping means composed of two cooperating pressure plates guided in chambers provided in the respective sealing member segments, said pressure plates having correspondingly applied entry openings for receiving a cable to be inserted therein, said clamping means including outer pressure means for urging pressure plates in the outer segment inward and inner pressure means for urging the pressure plates of the middle segment outward, said outer pressure means being arranged on the connecting elements.
Claim 2
Dependent Claim
193 words
