Abstract

This disclosure provides connectors for smart windows. A smart window may incorporate an optically switchable pane. In one aspect, a window unit includes an insulated glass unit including an optically switchable pane. A wire assembly may be attached to the edge of the insulated glass unit and may include wires in electrical communication with electrodes of the optically switchable pane. A floating connector may be attached to a distal end of the wire assembly. The floating connector may include a flange and a nose, with two holes in the flange for affixing the floating connector to a first frame. The nose may include a terminal face that present two exposed contacts of opposite polarity. Pre-wired spacers improve fabrication efficiency and seal integrity of insulated glass units. Electrical connection systems include those embedded in the secondary seal of the insulated glass unit.

First claim

What is claimed is:

1. A spacer of an insulated glass unit, the spacer comprising:
a body having surfaces configured to bond to two panes of the insulated glass unit; and
at least one flexible wire passing through or under the body of the spacer.

2. The spacer of claim 1 , wherein the at least one flexible wire is a ribbon cable.

3. The spacer of claim 1 , wherein:
the body comprises a hollow interior space, and
the at least one flexible wire passes through the hollow interior space.

4. The spacer of claim 1 , wherein the at least one flexible wire passes through a seal material between the two panes.

5. The spacer of claim 1 , wherein the at least one flexible wire passes between the body of the spacer and at least one pane of the two panes of the insulated glass unit.

6. The spacer of claim 1 , wherein the body is configured to hold the at least one flexible wire in place.

7. The spacer of claim 1 , wherein the at flexible wire passes through an aperture in the body of the spacer.

8. The spacer of claim 7 , wherein the aperture is sealed with adhesive.

9. The spacer of claim 1 , wherein the at least one flexible wire is in electrical communication with one or more of (i) a voltage source, (ii) a controller, and (iii) an optically switchable device disposed on one of the two panes of the insulated glass unit.

10. The spacer of claim 1 , wherein the at least one flexible wire comprises a plurality of wires running parallel to each other, wherein an end of the at least one flexible wire includes one or more connectors.

11. The spacer of claim 10 , wherein the one or more connectors are configured to connect to a window controller.

12. The spacer of claim 1 , wherein the at least one flexible wire is in electrical communication with one or more bus bars of an electrochromic device disposed on one of the two panes of the insulated glass unit.

13. The spacer of claim 1 , wherein the at least one flexible wire is configured to provide power and or communication signals to one or more devices disposed within, or on, the insulated glass unit.

14. The spacer of claim 1 , wherein the at least one flexible wire enters the body of the spacer at a first location and passes within an interior of the body of the spacer before exiting the spacer at a second location.

15. The spacer of claim 14 , wherein the interior of the body of the spacer is hollow.

16. The spacer of claim 1 , wherein the at least one flexible wire comprises at least one wire covered with insulation.

17. The spacer of claim 1 , wherein the body of the spacer is a unitary body.

18. The spacer of claim 1 , wherein the body of the spacer includes one or more tubular portions.

19. The spacer of claim 1 , wherein the body of the spacer comprises one or more metal portions.

20. The spacer of claim 19 , wherein at least one of the metal portions is bent.

21. The spacer of claim 1 , wherein the body of the spacer is a polymeric body.

22. The spacer of claim 1 , wherein the body of the spacer comprises an insulating coating.

23. The spacer of claim 1 , wherein the at one least flexible wire is configured to transmit signals to two or more electrochromic panes of the insulated glass unit.

24. An insulated glass unit comprising:
a first substantially transparent substrate;
a second substantially transparent substrate;
an optically switchable device disposed on one substantially transparent substrate of the first and second substantially transparent substrates; and
a spacer between, and at a periphery of, the first and second substantially transparent substrates, wherein the spacer comprises at least one flexible wire passing through the spacer, the least one flexible wire configured to provide power and or communication signals to the optically switchable device.

25. The insulated glass unit of claim 24 , wherein the at least one flexible wire is a ribbon cable.

26. The insulated glass unit of claim 24 , wherein the spacer comprises a body with a hollow interior space, and wherein the at least one flexible wire passes through the hollow interior space.

27. The insulated glass unit of claim 24 , wherein the spacer comprises a body and the at least one flexible wire passes between the body of the spacer and at least one substantially transparent substrate of the first and second substantially transparent substrates.

28. The insulated glass unit of claim 24 , wherein the at least one flexible wire passes through a seal material between a body of the spacer and at least one substantially transparent substrate of the first and second substantially transparent substrates.

29. The insulated glass unit of claim 24 , wherein the at least one flexible wire passes through a primary seal between a body of the spacer and the first substantially transparent substrate and the body of the spacer and the second substantially transparent substrate.

30. The insulated glass unit of claim 24 , wherein the spacer comprises a body configured to hold the at least one flexible wire.

31. The insulated glass unit of claim 24 , wherein the spacer comprises a body with an aperture, and wherein the at least one flexible wire passes through the aperture.

32. The insulated glass unit of claim 31 , wherein the aperture is sealed.

33. The insulated glass unit of claim 24 , wherein the at least one flexible wire is in electrical communication with a voltage source and/or a controller.

34. The insulated glass unit of claim 24 , wherein the at least one flexible wire includes a plurality of wires running parallel to each other, wherein an end of the at least one flexible wire includes one or more connectors configured to connect to a window controller.

35. The insulated glass unit of claim 24 , wherein the at least one flexible wire enters a body of the spacer at a first location and passes within an interior of the spacer before exiting the spacer at a second location.

36. The insulated glass unit of claim 35 , wherein the interior of the spacer is hollow.

37. The insulated glass unit of claim 24 , wherein the at least one flexible wire comprises at least one wire covered with insulation.

38. The insulated glass unit of claim 24 , wherein the spacer comprises a polymeric body.
