Abstract

A high voltage power distributor comprises an insulated high voltage power cable, a fuse mechanically connected to a fuse holder and a busbar that is electrically connected between the cable and the fuse. The fuse, the fuse holder, the busbar and the cable are accommodated in a housing.

First claim

The invention claimed is:

1. A high voltage power distributor, comprising:
an insulated high voltage power cable,
a fuse mechanically connected to a fuse holder;
a busbar that is electrically connected at a first end thereof to the cable and at a second end thereof to the fuse; and
a housing accommodating the fuse, the fuse holder, the busbar and at least a portion of the cable, wherein a first biased spring element is provided between the fuse holder and the housing configured to inhibit a movement of the fuse holder relative to the housing.

2. The high voltage power distributor according to claim 1 , wherein the cable in the housing is uninterrupted and the busbar is connected to a non-insulated section of the cable.

3. The high voltage power distributor according to claim 1 , wherein the busbar is welded to the cable.

4. The high voltage power distributor according to claim 1 , wherein the fuse holder comprises a slot for receiving an end of the busbar.

5. The high voltage power distributor according to claim 4 , wherein the slot supports the busbar at four sides thereof.

6. The high voltage power distributor according to claim 1 , wherein a second biased spring element is provided between the fuse holder and the housing and wherein spring forces of the first and second spring elements are oriented perpendicular to each other.

7. The high voltage power distributor according to claim 1 , wherein the fuse holder is L-shaped.

8. The high voltage power distributor according to claim 1 , wherein the cable extends in a substantially straight line through the housing.

9. The high voltage power distributor according to claim 1 , wherein the busbar extends transverse to the cable.

10. The high voltage power distributor according to claim 1 , wherein the busbar comprises an enlarged welding platform.

11. The high voltage power distributor according to claim 1 , wherein the fuse is rigidly connected to the cable.

12. The high voltage power distributor according to claim 1 , wherein the housing further accommodates an auxiliary outlet cable and a terminal of the auxiliary outlet cable and wherein the auxiliary outlet cable exits the housing through an outlet opening.

13. A method of manufacturing a high voltage power distributor, comprising:
partly removing an insulation of an insulated high voltage power cable;
electrically connecting a first end of a busbar to a section of the cable from which the insulation was removed and a second end of the busbar to a fuse;
connecting the fuse to a fuse holder; and
accommodating the cable, the busbar, the fuse, and the fuse holder in a housing; and
providing a first biased spring element between the fuse holder and the housing configured to inhibit a movement of the fuse holder relative to the housing.

14. The method according to claim 13 , wherein the busbar is inserted into a slot of the fuse holder before establishing the electrical connection between the busbar and the fuse.

15. The method according to claim 13 , wherein the fuse holder and the fuse are inserted into the housing while biasing the first spring element between the fuse holder and the housing.

16. The method according to claim 15 , further compromising:
providing a second biased spring element between the fuse holder and the housing; and
biasing the second spring element between the fuse holder and the housing such that spring forces of the first and second spring elements are oriented perpendicular to each other.

17. The method according to claim 13 , further compromising:
connecting a terminal of an auxiliary outlet cable to the fuse; and
accommodating the auxiliary outlet cable and the terminal of the auxiliary outlet cable within the housing, wherein the auxiliary outlet cable exits the housing through an outlet opening.
