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.

First claim

What is claimed is:

1. A window unit, comprising:
a first pane having an optically switchable device;
at least one other pane;
a spacer sandwiched between the first pane and the at least one other pane;
a secondary seal in at least a portion of an area (i) between the first pane and the at least one other pane, and (ii) outside the spacer; and
wiring housed within the secondary seal and in electrical communication with conductive layers of the optically switchable device.

2. The window unit of claim 1 , wherein the wiring is recessed relative to perimeter edges of the first pane and the at least one other pane.

3. The window unit of claim 1 , wherein the wiring is within a recess in the secondary seal.

4. The window unit of claim 1 , wherein the wiring is in a plug or a socket.

5. The window unit of claim 1 , wherein the wiring includes a first connector.

6. The window unit of claim 5 , wherein the first connector is at one end of the wiring and an other end of the wiring is in electrical communication with the conductive layers of the optically switchable device.

7. The window unit of claim 6 , wherein the other end of the wiring is electrically connected to bus bars, and wherein the bus bars are electrically connected to the conductive layers of the optically switchable device.

8. The window unit of claim 7 , wherein the wiring comprises a ribbon cable.

9. The window unit of claim 6 , further comprising a wire assembly having a second connector and a third connector, the second connector detachably connected to the first connector and the third connector configured for electrical communication with a power source.

10. The window unit of claim 9 , wherein the wire assembly is a pig-tail.

11. The window unit of claim 9 , wherein the wire assembly is disposed in a plug or a socket.

12. The window unit of claim 9 , wherein the third connector is configured for electrically coupling to a controller.

13. The window unit of claim 1 , wherein the secondary seal comprises a silicone-based sealant.

14. The window unit of claim 1 , wherein the at least one other pane is a laminate comprising multiple substrates.

15. The window unit of claim 1 , wherein the first pane and/or the at least one other pane comprises a glass sheet.

16. The window unit of claim 1 , wherein the optically switchable device is an electrochromic device.

17. The window unit of claim 16 , wherein the electrochromic device is solid state and inorganic.

18. The window unit of claim 1 , further comprising a primary seal between the spacer and the first pane and the at least one other pane.
