Sealed packages for electronic and energy storage devices
The present disclosure provides insulated assemblies for electronics packaging, the assemblies in some embodiments including an electrical connection extending through a tube that extends through an insulating vacuum space.
1. A header assembly, comprising:
a concave cap plug having upper and lower surfaces;
a cap having upper and lower surfaces,
the cap plug and the cap being sealably assembled to as to define an insulating volume within,
the insulating volume being defined by a lower surface of the cap and an upper surface of the cap plug,
the insulating volume being at a vacuum;
at least one cap tube having a lumen,
the lumen of the at least one cap tube extending through an aperture of the cap, through the insulating volume, and through an aperture of the cap plug.
2. The header assembly of claim 1 , further comprising a conductive connector extending through the lumen of the at least one cap tube.
3. The header assembly of claim 2 , further comprising an insulating material disposed within the lumen of the at least one cap tube so as to mechanically fix the conductive connector in position.
4. The header assembly of claim 3 , wherein the insulating material occupies sufficient volume within the lumen so as to interrupt fluid communication through the lumen.
5. The header assembly of claim 1 , further comprising an electronic device, an energy storage device, or any combination thereof disposed within a container sealably engaged with the header assembly.
6. The header assembly of claim 5 , wherein the electronic device or energy storage device is in electronic communication with the environment exterior to the header assembly.
7. The header assembly of claim 5 , wherein the header assembly interrupts fluid communication between the device within the container and the environment exterior to the container.
8. The header assembly of any claim 5 , wherein the container comprises at least two walls and a sealed vacuum between the at least two walls.
9. The header assembly of claim 3 , wherein the insulating material comprises a glass.
10. The header assembly of claim 2 , wherein the conductive connector comprises a wire, a pin, a lead, or any combination thereof.
11. The header assembly of claim 1 , wherein the cap and the cap plug are brazed to one another.
12. The header assembly of claim 1 , wherein the header assembly is fitted to an opening of a container so as to seal the opening of the container.
13. The header assembly of claim 12 , wherein the container is characterized as being cylindrical.
14. The header assembly of claim 12 , wherein the header assembly is affixed to the opening of the container.
15. The header assembly of claim 12 , wherein the container defines inner and outer closed walls, the container defining a volume enclosed within the inner wall, and the container further defining a region of reduced pressure being disposed between the first and second walls of the container.
16. The header assembly of claim 1 , wherein the insulating volume is at a pressure of from less than 760 Torr to about 1×10 −7 Torr.
17. The header assembly of claim 5 , comprising an electronic device disposed within the container sealably engaged with the header assembly.
18. The header assembly of claim 5 , comprising an energy storage device disposed within the container sealably engaged with the header assembly.
19. The header assembly of claim 12 , wherein the header assembly and container define a form factor identical to a AAA, AA, A, C, or D battery.
20. The header assembly of claim 12 , wherein the container is characterized as being polygonal.
