Abstract: A connector (1) for two electrical energy cables is indicated. The connector (1) has a plug (2) and a socket (3) which each is able to be tightly connected and suitable to produce a releasable electrical contact between the conductors. The socket (3) has hollow space (12) running in the longitudinal direction and the plug (2) a protruding bolt (11) in the longitudinal direction which is pluggable in the hollow space (12). The hollow space (12) and the bolt (11) have the identical truncated conical shape to each other, so that the bolt (11) is fixable in the hollow space (12) in the operative position. The connector (1) has further a pin (15, 18) so arranged that its axis is right angled to a connector axis (10) of the connector (1) and interacts with a circumferential recess (17, 18) around the diameter of the bolt (11).

Abstract: A method for electrically conductively connecting the electrical conductors (3, 4) of two high voltage cables (1, 2) is provided. The conductors (3, 4) are exposed at their ends by removing the respective casing and they are then inserted from different sides into a pipe piece (5) in such a way that they rest against each other with their end faces extending perpendicular to their axis and level with the central throughholes. The conductors (3, 4) are then secured by means of the securing screws (6) in the pipe piece 5 and bores extending in radial direction are made through the throughholes into which the two conductors (3, 4) project in the area of their end faces. Finally, the contact screws of an electrically well conductive metal are screwed into the central throughholes and further into the bores.

Abstract: A shear screw has predetermined breaking points in two planes, separated axially from one another, and it has centrally a blind hole extending over a substantial length and having a cross section which is suitable for transmitting a torque to the shear screw by means of a pin-like tool of adapted dimensions which can be inserted into the blind hole. The blind hole extends to about level with the predetermined breaking point which is arranged in the lower region, facing the end face of the shear screw, of the latter and has a strength greater than that of the other predetermined breaking point.
