Offset planar coil coaxial surge suppressor
View Patent ↗An in-line surge suppressor assembly having a body with a side aperture and an inner conductor positioned coaxial within a bore of the body. An insert having a planar inductor coil with a post extending from an origin point of the planar inductor coil is positioned with the post passing through the side aperture and coupled to the inner conductor at a distal end. An outer rim of the planar inductor coil is electrically coupled to the body.
1. An in-line surge suppressor assembly, comprising:
a body; an inner conductor positioned within a bore of the body; an insert mount at a side aperture of the body having an inner annular shoulder;
an insert having a planar inductor coil with an outer rim and a post extending from an origin point of the planar inductor coil; the planar inductor coil positioned outside of the bore;
the outer rim clamped against the inner annular shoulder by an end cap; and
a distal end of the post coupled to the inner conductor.
2. The assembly of claim 1 , wherein a plane of the planar inductor coil is parallel to a longitudinal axis of the inner conductor.
3. The assembly of claim 1 , wherein the planar inductor coil is positioned at least as far from an inner surface of the end cap as it is from the inner conductor.
4. An in-line surge suppressor assembly, comprising: a body having a side aperture and a bore; an inner conductor positioned coaxial within the bore; an end cap having an inner annular shoulder, the end cap threadable into the side aperture; an insert having a planar inductor coil with an outer rim and a post extending from an origin point of the planar inductor coil; the outer rim clamped between the inner annular shoulder and the body; the planar inductor coil positioned outside of the bore; a distal end of the post coupled to the inner conductor.
5. The assembly of claim 4 , wherein a plane of the planar inductor coil is parallel to a longitudinal axis of the inner conductor.
6. The assembly of claim 4 , wherein the outer rim is rigidly coupled to the inner annular shoulder; the distal end of the post threading into a threaded hole in the inner conductor as the end cap is threaded into the body.
7. An in-line surge suppressor assembly, comprising: a body with a side aperture; an inner conductor positioned coaxial within a bore of the body; a surge suppressor insert having a planar inductor coil with a post extending from an origin point of the planar inductor coil; the planar inductor coil positioned outside of the bore; the post passing through the side aperture and coupled to the inner conductor at a distal end; the body electrically coupled to the inner conductor through an outer rim of the planar inductor coil.
8. The assembly of claim 7 , wherein a plane of the planar inductor coil is parallel to a longitudinal axis of the inner conductor.
9. The assembly of claim 7 , wherein the distal end threads into a threaded hole in the inner conductor.
10. The assembly of claim 7 , wherein the planar inductor coil and the post are an integral component.
11. The assembly of claim 7 , wherein the planar inductor coil is a plurality of individual planar inductor coils stacked together to create a desired cross sectional area.
12. The assembly of claim 7 , further including a break in the inner conductor.
13. The assembly of claim 12 , wherein the break is a dielectric spacer inserted inline with the inner conductor.
14. The assembly of claim 7 , wherein the outer rim of the planar inductor coil is coupled to the body via a clamp connection between an inner annular shoulder and an end cap.
15. The assembly of claim 14 , wherein the inner annular shoulder is formed in an insert mount coupled to the body at the side aperture.
16. The assembly of claim 14 , wherein the inner annular shoulder is formed in an end cap coupled to the body at the side aperture.
17. The assembly of claim 14 , wherein the inner annular shoulder is formed in the body at the side aperture.
18. The assembly of claim 7 , further including a gas discharge tube electrically connected between the outer rim and the endcap.
19. The assembly of claim 18 , further including an end cap and an inner cap; the inner cap seated upon the outer rim and electrically insulated from the body; the gas discharge tube electrically coupled between the inner cap and the endcap; the end cap coupled to the body enclosing the inner cap and the gas discharge tube.
20. The assembly of claim 18 , further including a spring biased against the gas discharge tube.
