Abstract

The present invention is directed to a cable connecting device for fixing power cables and for producing an electrical connection between power cables. A bush having at least two cylindrical cavities, into which in each case a contact-making element can be inserted, has a contact sleeve serving to accommodate one end of a power cable. The bush also maintains contact-making bands on its outer side and has a locking device which, after the contact sleeve has been inserted into the cavity, secures the contact sleeve in its place.

The power cable can be electrically conductively connected to the contact sleeve and clamped in the latter by means of at least two screws on the outer side, which can be screwed into the circumferential wall of the contact sleeve. The screws are distributed over the outer circumference of the contact sleeve in such a way that they can be screwed onto the power cable at different angles.

Claims

1. A cable connecting device for fixing power cables and for producing an electrical connection between power cables, said cable connecting device comprising

a bush which has at least two cylindrical cavities into which in each case a contact-making element can be inserted, which has a contact sleeve serving to accommodate one end of a power cable and having contact-making bands on its outer side and has a locking device which, after the contact sleeve has been inserted into the cavity , secures said contact sleeve in its place;

it being possible for the power cable to be electrically conductively connected to the contact sleeve and clamped in the latter by means of at least two screws on the outer side which can be screwed into the circumferential wall of the contact sleeve, wherein the screws are distributed over the outer circumference of the contact sleeve in such a way that they can be screwed onto the power cable at different angles.

2. The cable connecting device according to claim 1, wherein the screw is formed as a shear-off head screw.

3. The cable connecting device according to claim 1, wherein each contact sleeve has a cylindrical interior.

4. The cable connecting device according to claim 1, wherein the locking device is formed as a spring ring which is arranged in a groove on the outer side of the contact sleeve and which expands into a notch formed in the inner wall of the cavity of the bush when the contact-making element is inserted into the cavity.

5. The cable connecting deviceaccording to claim 1, wherein the inner side of the contact sleeve is provided with internal grooving.
