Multiple planar inductive loop surge suppressor
View Patent ↗An in-line surge suppressor having a body with a bore. The body formed from a first portion and a second portion dimensioned to couple together. An inner conductor positioned within the bore and a shorting element extending between the inner conductor and the body. The shorting element having at least two loop segments, each of the loop segments arranged in a separate plane. Each of the loop segments interconnected with at least one other loop segment by a transition section.
1. An in-line surge suppressor device, comprising:
a body having a bore, the body formed from a first portion and a second portion dimensioned to couple together;
an inner conductor positioned within the bore;
a shorting element extending in a serial path between the inner conductor at a proximal end and the body at a distal end;
the shorting element having at least two loop segments; the loop segments each having a radius of curvature generally centered upon the inner conductor;
each of the loop segments arranged in a separate plane; each of the separate planes aligned parallel to one another and normal to a longitudinal axis of the inner conductor; and
each of the loop segments interconnected with at least one other loop segment by a transition section.
2. The surge suppressor of claim 1 , wherein the transition section includes a bend.
3. The surge suppressor of claim 1 , wherein the loop segments encircle the inner conductor with a varying radius.
4. The surge suppressor of claim 1 , wherein the loop segments have a varying cross sectional area.
5. The surge suppressor of claim 1 , wherein the loop segments comprise a plurality of linear segments.
6. The surge suppressor of claim 1 , wherein the transition segment is a separate component.
7. The surge suppressor of claim 1 , wherein the loop segments extend end to end encircling the inner conductor.
8. The surge suppressor of claim 1 , wherein the loop segments are arranged in a mirror orientation with respect to the transition section.
9. The surge suppressor of claim 1 , wherein the shorting element has a square cross section.
10. The surge suppressor of claim 1 , wherein the first portion and the second portion are coupled together by a swaged crimp connection.
11. The surge suppressor of claim 1 , further including a break in the inner conductor separated by a dielectric.
12. The surge suppressor of claim 11 , wherein the break is planar electrodes.
13. The surge suppressor of claim 11 , wherein the break is a pin dimensioned to fit into a socket spaced apart from the socket by the dielectric.
14. The surge suppressor of claim 13 , wherein the dielectric is a cylindrical sleeve dimensioned to fit over the pin.
15. The surge suppressor of claim 1 , wherein the shorting element is coupled to the body by a key formed in the distal end of the shorting element; the key dimensioned to mate with a slot formed in a seating surface between the first portion and the second portion.
16. The surge suppressor of claim 15 , wherein the key is formed by bending the distal end of the shorting element 90 degrees.
17. An in-line surge suppressor device, comprising:
a body having a bore, the body formed from a first portion and a second portion dimensioned to couple together;
an inner conductor positioned within the bore;
a shorting element extending in a single path between the inner conductor and the body;
the shorting element having a square cross section and at least two loop segments; each of the loop segments arranged in a separate plane; the separate planes are each aligned parallel to one another and normal to a longitudinal axis of the inner conductor; the loop segments encircling the inner conductor;
each of the loop segments interconnected with at least one other loop segment by a transition section having a bend;
the shorting element coupled to the body by a key dimensioned to fit into a slot formed in a seating surface between the first portion and the second portion.
18. A method of manufacturing a surge suppressor, comprising the steps of:
forming a first portion and a second portion which mate together to form a body having a bore;
positioning an inner conductor within the bore;
stamping a planar preliminary form having a desired pair of loop segments, connected in series, separated by a transition section;
converting the planar preliminary form into a shorting element by bending the loop segments at the transition section to arrange the loop segments into parallel planes; and
coupling the shorting element between the inner conductor and the body.
