Abstract
The invention relates to a coupling for power cables, consisting of a plug part and a socket part, said plug part having a basic body comprising a coupling pin on which a locking pin is arranged. The locking pin is movably mounted on the coupling pin so as to be displaceable in the axial direction of the coupling pin. The locking pin is biased to a basic position towards a back end of the coupling pin by a spring force. When the coupling is being locked, the locking pin engages a helical groove of the socket part and, thus, moves towards the front end of the coupling pin. This movement causes the spring device to load.
Claims20
A coupling for connecting a power cable in a fixed manner, comprising:
- a plug part including:
- a basic body;
- a coupling pin projecting over a front side of the basic body and arranged in the axial direction of the coupling;
- a locking pin that is movably mounted on the coupling pin, the locking pin being movable along the coupling pin in an axial direction;
- a spring device that biases the locking pin towards a back end of the coupling pin;
- and
- a first power cable that is electrically connected to the basic body of the plug part;
- and
- a socket part including:
- a basic body;
- an axial bore that extends through the basic body of the socket part and is sized to accommodate the coupling pin;
- a groove formed in a wall of the axial bore, the groove starting from a front side of the basic body of the socket part and comprising a helical segment, said groove serving to accommodate the locking pin of the plug part;
- and
- a second power cable that is electrically connected to the basic body of the socket part,
- wherein, when the coupling pin is inserted into the bore of the socket part, the locking pin is accommodated in the groove of the socket part and displaced towards a free end of the coupling pin and the spring device exerts a pre-load force on the locking pin, so that the plug part and the socket part are clamped against each other in an engagement connection and an electrical connection is formed between the first power cable and the second power cable.

A coupling for power cables comprising:
- a plug part that defines an end of a first power cable, the plug part comprising:
- a plug body with a front contact surface and a longitudinal axis that extends perpendicular to the front contact surface;
- and
- a locking pin that extends radially from the longitudinal axis and that is displaceable so that the locking pin is disposable at different distances beyond the front contact surface of the plug body;
- and
- a spring device configured to bias the locking pin towards the plug body;
- and
- a socket part that defines an end of a second power cable, the socket part comprising:
- a socket body with a front contact surface and a bore that allows the locking pin to move into the socket body;
- and
- a groove that is sized to receive the locking pin, the groove including an initial segment and a helical segment, the initial segment extending from the front contact surface of the main body of the socket part to the helical segment,
- wherein moving the locking pin along the groove of the socket part produces an engagement connection between the plug part and the socket part where the front contact surface of the plug part is secured in contact with the front contact surface of the socket part and the first power cable is electrically connected to the first power cable.

A plug part for a power coupling, comprising:
- a basic body with a front contact surface and a longitudinal axis that extends perpendicular to the front contact surface;
- and
- a power cable that is electrically connected to the basic body of the plug part;
- a coupling pin that projects beyond the front contact surface of the basic body along the longitudinal axis;
- a locking pin that extend radially from the coupling pin and that is displaceable with respect to the coupling pin so that the locking pin is disposable at different distances beyond the front contact surface of the basic body;
- and
- a spring device configured to bias the locking pin towards the basic body, wherein upon insertion into a socket part, the locking pin is displaced away from the basic body and the spring device secures the front contact surface of the plug part to the socket part while the power cable is electrically connected to a power cable included in the socket part.
