Abstract

Electricity bolt for electrical contact of a printed circuit board with an electric conductor, with a basic body, wherein the basic body can be electrically contacted by a first section with the printed circuit board, and by a second section with the electric conductor, wherein the basic body at least in the area of the first section, by which the basic body is electrically conductively contactable with the printed circuit board, is designed as a hollow component, into which for the electrical contact with the printed circuit board a screw is so screwed that the first section is radially outwardly expandable by the screw.

First claim

The invention claimed is:

1. An electricity bolt for electrical contact of a printed circuit board with an electric conductor, the electricity bolt comprising:
a basic body comprising a first section and a second section, the first section in electrical contact with the printed circuit board and the second section in electrical contact with the electric conductor;
wherein the first section of the basic body comprises a hollow component, wherein a screw is positioned in the hollow component to radially outwardly widen the first section of the basic body; and
wherein the first section comprises an internal thread in the basic body, wherein the screw which is used for the radial expansion of the first section of the basic body can be screwed into the internal thread.

2. The electricity bolt of claim 1 , wherein the screw starting from the second section of the basic body can be screwed into the same.

3. The electricity bolt of claim 1 , wherein the screw which is used for the radial expansion of the first section of the basic body is designed as a tapered screw.

4. The electricity bolt of claim 1 , wherein the basic body in the area of the second section, by which the basic body is electrically contactable with the electric conductor, is designed as a hollow part, in which a further screw can be screwed in such a manner that the electric conductor can be clamped between the second section and the further bolt.

5. The electricity bolt of claim 1 , wherein the basic body is carried out entirely as a hollow part seen in the longitudinal direction.

6. The electricity bolt of claim 1 , wherein the first section of the basic body comprises at least one slot extending in longitudinal direction.

7. The electricity bolt of claim 6 , wherein the basic body has a recess in the area of the first section, which limits the insertion depth of the first section of the basic body into a recess of the printed circuit board, wherein the slot extends on both sides of the recess seen in the longitudinal direction of the basic body.

8. The electricity bolt of claim 6 , wherein the first section comprises an internal thread in the basic body, and wherein the screw which is used for the radial expansion of the first section of the basic body can be screwed into the internal thread.

9. The electricity bolt of claim 6 , wherein the screw starting from the second section of the basic body can be screwed into the same.

10. The electricity bolt of claim 6 , wherein the screw which is used for the radial expansion of the first section of the basic body is designed as a tapered screw.

11. The electricity bolt of claim 6 , wherein the basic body in the area of the second section, by which the basic body is electrically contactable with the electric conductor, is designed as a hollow part, in which a further screw can be screwed in such a manner that the electric conductor can be clamped between the second section and the further bolt.

12. The electricity bolt of claim 6 , wherein the basic body is carried out entirely as a hollow part seen in the longitudinal direction.

13. The electricity bolt of claim 6 , wherein the first section of the basic body comprises a plurality of longitudinally extending slots that divide the first section into a plurality of circumferential segments, when the circumferential segments can be pressed radially outward by the screw.

14. The electricity bolt of claim 13 , wherein the basic body has a recess in the area of the first section, which limits the insertion depth of the first section of the basic body into a recess of the printed circuit board, wherein each slot extends on both sides of the recess seen in the longitudinal direction of the basic body.

15. The electricity bolt of claim 13 , wherein the first section comprises an internal thread in the basic body, and wherein the screw which is used for the radial expansion of the first section of the basic body can be screwed into the internal thread.

16. The electricity bolt of claim 13 , wherein the basic body in the area of the second section, by which the basic body is electrically contactable with the electric conductor, is designed as a hollow part, in which a further screw can be screwed in such a manner that the electric conductor can be clamped between the second section and the further bolt.

17. The electricity bolt of claim 13 , wherein the basic body is carried out entirely as a hollow part seen in the longitudinal direction.

18. The electricity bolt of claim 1 , wherein the screw starting from the first section of the basic body can be screwed into the same.

19. The electricity bolt of claim 18 , wherein the screw which is used for the radial expansion of the first section of the basic body is designed as a tapered screw.
