Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
186 words
In a cap sleeve, which is composed of an envelope body and at least one actual sealing member arranged to close an opening in the envelope body, said sealing member having cable introduction openings for sealingly receiving cables and having a radially opening, outer circumferential groove receiving a sealing element to form an annular sealing system between the envelope body and an outer circumference of the sealing member, the improvements comprising the sealing system including a ring-shaped shaped adapter for increasing an external groove edge of the circumferential groove, said adapter having a ring-shaped projection on an exterior surface, which has a slanted bevel that flares outwardly, the envelope body having a conically bevelled flange extending radially outward and with a diameter matched to a diameter of the projection, the sealing element being inserted between the flange of the envelope body and the projection of the adapter and the system including a clamp ring with an inwardly directed groove, whose edges have matched conical bevellings receiving the projection and flange in a clamped fashion to exert an axial closing force on the sealing element disposed therebetween.
