Abstract

A capacitor fastening for fastening a capacitor to a panel, whereby the capacitor, when mounted in place, is positioned in the panel, fastened at its lower part. The capacitor fastening includes a retainer in the panel at the mounting point of the capacitor for preventing lateral movement of the capacitor in at least one selected direction; a tightening plate arranged above the panel and to be fastened to the panel, which tightening plate has a hole substantially corresponding to the diameter of the capacitor above the mounting point of the panel; and a wedge between the panel and the tightening plate for tightening the retainer of the panel and the edge of the hole in the tightening plate from opposite directions against the capacitor.

First claim

What is claimed is:

1. A capacitor fastening for fastening a capacitor, the capacitor fastening comprising:
a panel for fastening to a lower part of the capacitor;
a retainer at a mounting point of the capacitor in the panel for preventing a lateral movement of the capacitor in at least one selected direction;
a tightening plate for arranging above the panel and for fastening to the panel, the tightening plate having a hole substantially corresponding to a diameter of the capacitor above the mounting point of the panel; and
a wedge between the panel and the tightening plate for tightening the capacitor in place between the panel and the plate,
wherein the wedge includes wedging pins in the panel and corresponding wedging holes in the tightening plate, which, when brought into co-operation, are arranged to tighten the retainer of the panel and an edge of the hole of the tightening plate against each other in opposite directions around the capacitor in directions perpendicular to an axial direction of the capacitor.

2. The capacitor fastening as claimed in claim 1 , wherein the retainer of the panel comprises:
a curved collar matching a shape of an outer surface of the capacitor rising from the panel, the collar extending on a first predetermined distance around the capacitor.

3. The capacitor fastening as claimed in claim 1 , wherein the hole in the tightening plate comprises:
a downward collar which is on an opposite side of the capacitor in relation to the collar of the panel and extends in a second predetermined distance around the capacitor.

4. The capacitor fastening as claimed in claim 2 , wherein the hole in the tightening plate comprises:
a downward collar which is on an opposite side of the capacitor in relation to the collar of the panel and extends in a second predetermined distance around the capacitor.

5. The capacitor fastening as claimed in claim 2 , wherein the collar of the panel comes substantially into contact with a bottom surface of the tightening plate and the collar of the hole in the tightening plate comes substantially into contact with a top surface of the panel, the collars extending in each case a distance of 180° at the most around the capacitor.

6. The capacitor fastening as claimed in claim 3 , wherein the collar of the panel comes substantially into contact with a bottom surface of the tightening plate and the collar of the hole in the tightening plate comes substantially into contact with a top surface of the panel, the collars extending in each case a distance of 180° at the most around the capacitor.

7. The capacitor fastening as claimed in claim 4 , wherein the collar of the panel comes substantially into contact with a bottom surface of the tightening plate and the collar of the hole in the tightening plate comes substantially into contact with a top surface of the panel, the collars extending in each case on a distance of 180° at the most around the capacitor.

8. The capacitor fastening as claimed in claim 1 , wherein the retainer of the panel comprises:
a recess made to the panel matching a shape of a capacitor bottom.

9. The capacitor fastening as claimed claim 1 , wherein the wedging pins are conical.

10. The capacitor fastening as claimed claim 2 , wherein the wedging pins are conical.

11. The capacitor fastening as claimed claim 3 , wherein the wedging pins are conical.

12. The capacitor fastening as claimed claim 4 , wherein the wedging pins are conical.

13. The capacitor fastening as claimed in claim 1 , comprising:
a screw fastener for fastening the panel and the fastening plate together, the screw fastener acting at the same time as a tightening mechanism for the wedge.

14. The capacitor fastening as claimed in claim 1 , wherein the panel, the tightening plate and the wedge are formed for fastening a plurality of capacitors, the size of the capacitors to be fastened being thus also freely selectable.

15. The capacitor fastening as claimed in claim 2 , comprising:
a screw fastener for fastening the panel and the fastening plate together, the screw fastener acting at the same time as a tightening mechanism for the wedge.

16. The capacitor fastening as claimed in claim 3 , comprising:
a screw fastener for fastening the panel and the fastening plate together, the screw fastener acting at the same time as a tightening mechanism for the wedge.

17. The capacitor fastening as claimed in claim 2 , wherein the panel, the tightening plate and the wedge are formed for fastening a plurality of capacitors, the size of the capacitors to be fastened being thus also freely selectable.

18. The capacitor fastening as claimed in claim 3 , wherein the panel, the tightening plate and the wedge are formed for fastening a plurality of capacitors, the size of the capacitors to be fastened being thus also freely selectable.

19. The capacitor fastening as claimed in claim 4 , wherein the panel, the tightening plate and the wedge are formed for fastening a plurality of capacitors, the size of the capacitors to be fastened being thus also freely selectable.

20. A capacitor, in combination with the capacitor fastening as claimed in claim 1 .
