Abstract: A cable clamp serving for mounting in an opening in e.g. a wall and enveloping a cable inserted through the opening. The cable clamp comprises a threaded nipple and a threaded socket that when screwed together are defining an axis and defining an axially extending leading-in channel for the cable, an annular gasket placed intermediately in this channel and arranged to be compressed around the cable when the nipple and the socket are screwed together, and a relieving clamp for subsequently clamping the cable in the cable clamp. By means of a lock in form of a radial rib on the nipple and a corresponding radial groove in the socket the cable clamp is locked in the correct screwed-together state in which the connection is given the required tightness. The cable clamp is generally applicable for cables within a predetermined diameter interval, and is secured against damage at assemblage.

Abstract: A cable lead-in including an upper part and a lower part. The upper part and the lower part are clamped together by a threaded joint in an opening in a wall on a casing around current conductors, which are connected via an electric cable to other current conductors outside the casing. The upper part is formed with a through duct, which has an outer funnel-shaped duct section and an inner threaded section. A seat for a sealing ring is formed between these two sections. A nipple having a strain relief strap is screwed into the threaded section, whereby the sealing ring is pressed sealingly against both the seat and the cable. The funnel-shaped duct section serves to protect the cable against damage by bending in operation. The nipple has a hexagonal head, and at least one of a plurality of blind holes in the upper part accommodates a self-tapping screw whose head is spaced closely from one of the faces of the hexagonal nipple head.
