Abstract

An in-line capacitor, having a pair of inner conductor segments, each of the inner conductor segments having a mating surface. A dielectric spacer positioned between the mating surfaces, each of the mating surfaces having corresponding folds formed thereon.

Claims (33)

1. An in-line capacitor, comprising:

a pair of inner conductor segments, each of the inner conductor segments having a mating surface;

a solid dielectric spacer positioned between the mating surfaces;

each of the mating surfaces having corresponding folds formed thereon; whereby the mating surfaces with the solid dielectric spacer there between is a capacitor; and

the inner conductor segments are each supported by an insulator coaxial within a bore of a surrounding housing.

2. The in-line capacitor of claim 1 , wherein the mating surfaces are coaxial with the inner conductor segments.

3. The in-line capacitor of claim 1 , wherein the folds create a lateral interlock between the mating surfaces.

4. The in-line capacitor of claim 3 , wherein the folds are concentric circles.

5. The in-line capacitor of claim 1 , wherein the folds create a rotational interlock between the mating surfaces.

6. The in-line capacitor of claim 5 , wherein the folds are radial.

7. The in-line capacitor of claim 5 , wherein the folds are concentric polygons.

8. The in-line capacitor of claim 1 , wherein the dielectric spacer is a ceramic material.

9. The in-line capacitor of claim 1 , wherein the dielectric spacer has folds corresponding to each of the mating surfaces, a gap between the mating surfaces generally equal to a thickness of the dielectric spacer.

10. The in-line capacitor of claim 1 , wherein the folds are concentric about a center of the mating surface.

11. The in-line capacitor of claim 1 , wherein the dielectric spacer has corresponding dielectric spacer folds of equal depth, a first generally planar surface passing through a peak dimension of the dielectric spacer folds and a second generally planar surface passing through a valley dimension of the dielectric spacer folds, the first and the second generally planar surfaces parallel to one another.

12. The in-line capacitor of claim 1 , wherein the dielectric spacer has corresponding dielectric spacer folds whereby the dielectric spacer has a generally conical section.

13. The in-line capacitor of claim 1 , further including an inductor coupled between one of the inner conductor segments and the housing.

14. The in-line capacitor of claim 1 , further including a coaxial connection interface at each of a first and a second end of the housing.

15. A method for manufacturing an in-line capacitor, comprising the steps of:

forming a pair of inner conductor segments, each of the inner conductor segments having a mating surface; and

positioning a solid dielectric spacer between the mating surfaces;

each of the mating surfaces having corresponding folds formed thereon; whereby the mating surfaces with the solid dielectric spacer there between is a capacitor; and

forming a housing with a bore and inserting the pair of inner conductor segments and the solid dielectric spacer within the bore.

16. The method of claim 15 , further including the step of forming the dielectric spacer from a ceramic material.

17. The method of claim 15 , further including the step of coupling a surge element between one of the inner conductor segments and the housing.

18. The method of claim 15 , wherein the housing has two portions, the two portions joined together via swaging of one end upon another.

19. An in-line capacitor, comprising:

a pair of inner conductor segments, each of the inner conductor segments having a mating surface; and

a ceramic dielectric spacer positioned between the mating surfaces;

each of the mating surfaces having corresponding folds formed thereon;

the inner conductor segments and the ceramic dielectric spacer surrounded coaxially by a housing having coaxial connection interfaces at a first end and at a second end; whereby the mating surfaces with the ceramic dielectric spacer there between is a capacitor.

20. The in-line capacitor of claim 19 further including a surge element coupled between one of the inner conductor segments and the housing.

21. The in-line capacitor of claim 19 , wherein the folds form a lateral movement interlock between the mating surfaces.
