Abstract

A sealed feedthrough connector can include a non-conductive clamp plate having at least one first conductor aperture and further including at least one conductor having a first end connecting to electronics in a high-power electronics chassis. The conductor can include a second end connecting to a circuit external to the electronics chassis, with a shoulder between the first and second ends. The connector can include a non-conductive terminal panel, a plate seal, and a conductor seal, the terminal panel having at least one second conductor aperture. The non-conductive clamp plate can be secured to the non-conductive terminal panel with a wall of the electronics chassis and the plate seal between them. At least one conductor can extend the first end through the first conductor aperture and the second end through the second conductor aperture, the conductor seal being positioned between the shoulder and the clamp plate or the terminal panel.

First claim

What is claimed is:

1. A high-power sealed feedthrough connector assembly for a high-power electronics chassis, the connector assembly comprising:
a non-conductive clamp plate having at least one first conductor aperture;
at least one conductor having a first end configured to connect to electronics in the high-power electronics chassis, a second end configured to connect to a circuit external to the high-power electronics chassis, and a shoulder between the first and second ends;
an exterior non-conductive terminal panel having at least one second conductor aperture;
a plate seal; and
a conductor seal,
wherein the non-conductive clamp plate is configured to be secured to the exterior non-conductive terminal panel with a wall of the high-power electronics chassis and the plate seal between them, and the at least one conductor having the first end extending through the at least one first conductor aperture and the second end extending through the at least one second conductor aperture with the conductor seal between the shoulder and the non-conductive clamp plate or the exterior non-conductive terminal panel.

2. The connector assembly of claim 1 further comprising a shoulder recess in one of the clamp plate or the terminal panel and receivable of the shoulder, a perimeter of the shoulder being keyed to the shoulder recess for preventing rotation of the conductor.

3. The connector assembly of claim 2 wherein the perimeter of the shoulder is a rectangle.

4. The connector assembly of claim 1 further comprising a boss projecting from the terminal panel and shaped complimentary to an opening in the wall receivable of the boss.

5. The connector assembly of claim 4 wherein the plate seal is an O-ring positionable around the boss.

6. The connector assembly of claim 4 further comprising a boss groove disposed on a wall-facing surface of the terminal panel adjacent the boss, the boss groove for positioning the plate seal against the wall.

7. The connector assembly of claim 4 further comprising a shoulder recess in the boss and receivable of the shoulder, a perimeter of the shoulder being keyed to the shoulder recess for preventing rotation of the conductor.

8. The connector assembly of claim 7 wherein the perimeter of the shoulder is a rectangle.

9. The connector assembly of claim 1 wherein the conductor seal is an O-ring.

10. The connector assembly of claim 9 further comprising an aperture groove disposed on a wall-facing surface of the terminal panel adjacent the second conductor aperture, the aperture groove for positioning the conductor seal against the shoulder.

11. The connector assembly of claim 1 further comprising, when there are at least two of the at least one second conductor aperture, a non-conductive partition extending from the terminal panel between two of the at least two second conductor apertures and operable to dedicate a volume of space around the second end.

12. The connector assembly of claim 11 further comprising a shroud fastenable to the terminal panel and configured to house the partition and the volume of space.

13. An electronics chassis having a wall and a feedthrough connector comprising:
a non-conductive clamp plate on an interior of the wall of the electronics chassis and having a first conductor aperture;
at least one conductor extending through the first conductor aperture and the wall and having a first end connected to electronics in the electronics chassis;
an exterior non-conductive terminal panel on an exterior of the wall of the electronics chassis and secured to the clamp plate and having at least one second conductor aperture with a second end of the at least one conductor extending through the at least one second conductor aperture; and
wherein a plate seal is clamped between the wall of the chassis and the clamp plate or the terminal panel, and wherein a conductor seal is clamped between a shoulder of the at least one conductor and the clamp plate or the terminal panel.

14. The feedthrough connector of claim 13 further comprising a boss projecting from the terminal panel and shaped complimentary to an opening in the wall receivable of the boss.

15. The feedthrough connector of claim 14 wherein the plate seal is an O-ring around the boss.

16. The feedthrough connector of claim 14 further comprising a boss groove disposed on a wall-facing surface of the terminal panel adjacent the boss and positioning the plate seal against the wall.

17. The feedthrough connector of claim 14 further comprising a shoulder recess in the boss and receiving the shoulder, the shoulder keyed to the shoulder recess to prevent rotation of the conductor.

18. The feedthrough connector of claim 17 wherein the shoulder and the shoulder recess key to each other at a rectangular perimeter of the shoulder.

19. The feedthrough connector of claim 13 further comprising an aperture groove disposed on a wall-facing surface of the terminal panel adjacent the second conductor aperture and positioning the conductor seal against the shoulder.

20. The feedthrough connector of claim 13 further comprising, when there are at least two of the at least one second conductor aperture, a non-conductive partition extending from the terminal panel between two of the at least two second conductor apertures and operable to dedicate a volume of space around the second end.
