Multiple planar inductor coaxial surge suppressor
View Patent ↗An in-line surge suppressor having a body with a bore between two ends and at least one channel located within the body and around the bore. An inner conductor is located within the bore. A shorting element has a plurality of segments that extend from the inner conductor, through extension grooves between the channel and the bore, into a common or separate channel(s). The segments coupled to the channel(s), proximate a distal end of each segment.
1. An in-line surge suppressor device, comprising:
a body having a bore, the body formed from a first portion and a second portion adapted to couple together;
at least one of the first and the second portions having at least one groove that forms at least one enclosed channel when the first portion and the second portion are coupled together;
a shorting element extending between an inner conductor within the bore and the body, the shorting element having a plurality of extension segments extending from the inner conductor through a corresponding plurality of extension grooves in the body to the channel(s); and
a curved segment extending along the channel(s) from each extension segment, a distal end of each curved segment having a contact electrically connected to the body.
2. The device of claim 1 , wherein there are two extension segments.
3. The device of claim 2 , wherein the curved segment(s) extending from each of the two extension segments are arranged within a single channel.
4. The device of claim 2 , wherein the extension segments overlap one another in the single channel, isolated from each other.
5. The device of claim 2 , wherein the curved segment(s) extending from each of the two extension segments are arranged each within a separate channel.
6. The device of claim 5 , wherein the separate channel(s) overlap one another.
7. The device of claim 1 , wherein the extension segments project radially from the inner conductor, equidistant from each other.
8. The device of claim 1 , wherein the curved segment(s) are electrically insulated, except for the contact.
9. The device of claim 1 , wherein the curved segment(s) are biased inward or outward, whereby the contact(s) are biased into electrical contact with the channel, upon insertion of the curved segment(s) into the channel.
10. The device of claim 1 , wherein the inner conductor has a break separated by a dielectric.
11. An in-line surge suppressor, comprising:
a body having a bore;
a channel within the body and around the bore;
an inner conductor located within the bore;
a shorting element with a plurality of segments extending from the inner conductor,
through extension grooves between the channel and the bore, into the channel;
the segments each coupled proximate a distal end to the channel.
12. The device of claim 11 , wherein the inner conductor has a break separated by a dielectric.
13. The device of claim 11 , wherein a length of the segments within the channel is selected to minimize return loss within a desired frequency band.
14. The device of claim 11 , wherein the body is formed from two portions adapted to couple together.
15. The device of claim 14 , wherein the two portions couple together via threads that are environmentally sealed by a gasket.
16. The device of claim 11 , wherein the segment(s) within the channel are electrically insulated from the channel, except for the distal end(s).
17. An in-line surge suppressor, comprising:
a body having a bore extending between two ends,
an inner conductor positioned coaxial within the bore,
a shorting element with a plurality of segments extending from the inner conductor,
through a corresponding plurality of extension grooves in the body, to a channel around the bore; the bore having a substantially constant diameter between the two ends.
18. The device of claim 17 , wherein the shorting element has curved segments that extend along the channel;
a distal end of each curved segment having a contact in electrical contact with the channel.
19. The device of claim 17 , wherein the shorting element has two extension segments extending radialy from the inner conductor to the channel;
the extension segments formed with a common axis.
20. The device of claim 17 , wherein the segment(s) within the channel are electrically insulated from the channel, except for a distal end(s) of the segment(s).
