Abstract

A signal generator is suggested for a mounting on holding tubes, having a base element for being placed on the holding tube and a fastening element for fixing the base element on the holding tube, which requires low expenditures during the manufacturing and ensures a reliable fixing. According to the invention, this is achieved in that the fastening element cuts form-lockingly into the material of the holding tube (4) and of the base element (1).

Claims

1. A signal generator base, comprising:

a holding tube;

a base element arranged on the holding tube, the base element having a recess extending parallel to the holding tube and being open on an interior side facing the holding tube;

a fastening element having a threaded area, the fastening element being received in the recess so as to cut form-lockingly into the holding tube and the base element, wherein a material of the fastening element, at least in the threaded area is harder than a material of the holding tube, and further wherein a diameter of the threaded-area of the fastening element is at least partially larger than a clear measurement of the recess between the holding tube and the base element; and

at least one sealing element sealing between the base element and the holding tube.

2. The signal generator base according to claim 1, wherein the recess is accessible on a face side of the base element.

3. The signal generator base according to claim 1, wherein the recess is accessible from a face of the base element facing a signal generator.

4. The signal generator base according to claim 1, wherein the fastening element is a screw.

5. The signal generator base according to claim 1, wherein the fastening element is a screw screwed into the recess parallel to the holding tube.

6. The signal generator base according claim 1, wherein an insulation element is provided for insulating bared cable areas on the base element.

7. The signal generator base according to claim 1, wherein the holding tube has a smooth outer surface in an area engageable with the threaded area of the fastening element.

8. A signal generator, comprising:

a base element;

a signal element coupled to the base element;

a holding tube on which is arranged the base element;

wherein the base element has a recess extending parallel to the holding tube and being open on an interior side facing the holding tube;

a fastening element having a threaded area, the fastening element being received in the recess so as to cut form-lockingly into the holding tube and the base element, wherein a material of the fastening element, at least in the threaded area is harder than a material of the holding tube, and further wherein a diameter of the threaded-area of the fastening element is at least partially larger than a clear measurement of the recess between the holding tube and the base element; and

at least one sealing element sealing between the base element and the holding tube.

9. The signal generator according to claim 8, wherein the holding tube has a smooth outer surface in an area engageable with the threaded area of the fastening element.
