Abstract

A connection device for connecting electrical conductors includes a sheath clamp comprising a bottom part and a top part, a contact carrier to which the bottom portion of the sheath clamp is attached, and a detachable insulating cap configured for rotabably receiving the top part of the sheath clamp, wherein the detachable insulating cap is permanently connected to the contact carrier.

First claim

What is claimed is:

1. A connection device for connecting electrical conductors, comprising:
a sheath clamp comprising a bottom part of the sheath clamp and a top part of the sheath clamp;
a contact carrier to which the bottom part of the sheath clamp is attached; and
a detachable insulating cap configured to hold the top part of the sheath clamp, wherein the top part of the sheath clamp is rotatable inside the detachable insulating cap, and wherein the detachable insulating cap is connected to the contact carrier via a flexible section, wherein the flexible section is formed from non-conductive material.

2. The connection device according to claim 1 , wherein the insulating cap is insertable into the contact carrier.

3. The connection device according claim 1 , wherein the contact carrier comprises two opposite guide grooves configured to guide the insulating cap inside the contact carrier.

4. The connection device according to claim 3 , wherein the insulating cap comprises two guide sections configured for insertion in the opposite guide grooves of the contact carrier.

5. The connection device according to claim 1 , wherein the insulating cap comprises a swivel arm configured for tiltable attachment of the insulating cap to the contact carrier.

6. The connection device according to claim 5 , wherein the swivel arm comprises two opposite pivots.

7. The connection device according to claim 6 , wherein the contact carrier comprises two pivot guide grooves configured for slidable insertion of the insulating cap by means of the opposite pivots.

8. The connection device according to claim 1 , wherein the insulating cap comprises a pin configured for rotatable attachment of the insulating cap to the contact carrier, wherein the pin extends parallel to a rotation axis of the top part of the sheath clamp.

9. The connection device according to claim 1 , wherein a metal contact bridge is attached to the insulating cap and configured to exert a pressing force onto the electrical conductors.

10. The connection device according to claim 9 , wherein the metal contact bridge is attached to one or more guide sections of the insulating cap.

11. The connection device according to claim 9 , wherein the metal contact bridge overlaps the top part of the sheath clamp.

12. The connection device according to claim 9 , wherein the top part of the sheath clamp comprises a peg configured to exert a pressing force onto the metal contact bridge, wherein the peg is arranged on a rotation axis of the top part of the sheath clamp.

13. The connection device according to claim 1 , wherein an electrically insulating contact protection element is arranged between a top side of the top part of the sheath clamp and the insulating cap.

14. The connection device according to claim 13 , wherein the contact protection element comprises a slot configured for insertion of a turning tool.

15. A connection device for connecting electrical conductors, comprising:
a sheath clamp comprising a bottom part of the sheath clamp and a top part of the sheath clamp;
a contact carrier to which the bottom part of the sheath clamp is attached; and
a detachable insulating cap configured to hold the top part of the sheath clamp, wherein the top part of the sheath clamp is rotatable inside the detachable insulating cap, and wherein the detachable insulating cap is connected to the contact carrier,
wherein a metal contact bridge is attached to the insulating cap and configured to exert a pressing force onto the electrical conductors.

16. The connection device according to claim 15 , wherein the metal contact bridge is attached to one or more guide sections of the insulating cap.

17. The connection device according to claim 15 , wherein the metal contact bridge overlaps the top part of the sheath clamp.

18. The connection device according to claim 15 , wherein the top part of the sheath clamp comprises a peg configured to exert a pressing force onto the metal contact bridge, wherein the peg is arranged on a rotation axis of the top part of the sheath clamp.
