Abstract

Abstract In order to ensure a tight feed-in of the cable end in a fitting for plastic insulated electric cables, which includes an elastic, prefabricated insulator with a metallic housing, even if the cable is bent, a circular slot, the depth of which corresponds approximately to the length of the cylindrical base part of a control deflector embedded on the inside in the end of the insulating body of the insulator, is made in the cylindrical end of the insulator at the end face. The slot separates the elastic control part of the fitting into a mechanically effective and an electrically effective region.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 106 words
In a fitting for plastic insulated electric cables, especially for medium and high voltage cables, comprising an elastic, prefabricated insulator provided with a hole and which has at least one cylindrical end with a control deflector of elastomer material embedded on the inside, said deflector having a cylindrical base part followed by conical part, and a metallic housing surrounding the insulator, the improvement comprising a circular slot concentric to the axis of the insulator formed in the cylindrical end of the insulator at the end face, and the depth of said slot corresponding approximately to the length of the cylindrical base part of the control deflector.
Claim 2
Dependent Claim 106 words
