Cover element for an electrical connector

1. An electrical connector for connecting or finishing at least one cable, comprising:

an electrically conductive connector sheath having a borehole and a cable receiver receiving an end section of the cable; and

a cover having a cylindrical disc including a first cover surface with a convex form having a cylindrical or spherical curvature and a radius corresponding to an outer radius of the connector sheath, an opposite second cover surface, and a barrel surface extending between the first cover surface and the second cover surface, the first cover surface having a same diameter as the second cover surface, and in a state in which the cover is mounted on the electrical connector and received in the borehole, the first cover surface forms a portion of an outer surface of the electrical connector and the second cover surface faces an inner side of the electrical connector.

2. The electrical connector of claim 1 , wherein the borehole receives a fixing element which fixes the cable in the cable receiver.

3. The electrical connector of claim 1 , wherein the barrel surface has an outer thread.

4. The electrical connector of claim 3 , wherein the borehole has an inner surface, the outer thread of the barrel surface engaging with the inner surface of the borehole to fix the cover in the borehole.

5. The electrical connector of claim 1 , wherein the cover is formed from an electrically conductive material.

6. The electrical connector of claim 5 , wherein the electrically conductive material is aluminum or a conductive plastic.

7. The electrical connector of claim 1 , wherein the cover has an actuator for mounting or demounting the cover in the borehole.

8. The electrical connector of claim 7 , wherein the actuator has a driving profile engaging a corresponding tool.

9. The electrical connector of claim 1 , wherein the convex form of the first cover surface is fixed with respect to the cylindrical disc.
