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. An electrical connection system for a sliding door or window, the electrical connection system comprising:
a guide comprising a recess within which pass one or more wires for electrical communication between at least a power source and an optically switchable device in the sliding door or window, the guide further comprising an outer surface and a lengthwise slot in the outer surface; and
a shuttle configured to couple to the sliding door or window and to slideably engage with the lengthwise slot in the guide, the shuttle further configured to pass the one or more wires from the sliding door or window, through a body of the shuttle into the recess of the guide, wherein during movement of the sliding door or window, the one or more wires are protected from interaction with one or more moving components.

2. The electrical connection system of claim 1 , further comprising a flexible member affixed at one end to the shuttle, the one or more wires coupled to the flexible member, wherein the flexible member comprises a bend portion allowing the flexible member to pass back over itself and reside substantially parallel to the length of, and inside, the guide.

3. The electrical connection system of claim 2 , wherein the one or more wires are supported on a ribbon cable and the flexible member is a spring steel tape.

4. The electrical connection system of claim 2 , wherein the flexible member is a chain guide made of a non-electrically conducting material, and the one or more wires reside within the body of the chain guide.

5. The electrical connection system of claim 3 , wherein the shuttle is slideably engaged with the sliding door or window in the vertical direction.

6. The electrical connection system of claim 5 , wherein a vertical portion of the body of the shuttle passes through an aperture in a base plate affixed to the sliding door or window.

7. The electrical connection system of claim 5 , wherein the body of the shuttle is made of a plastic material.

8. The electrical connection system of claim 5 , wherein the guide further comprises an open end so that the shuttle may be inserted into the lengthwise slot through the open end of the guide during assembly of the electrical connection system.

9. The electrical connection system of claim 4 , wherein the shuttle is slideably engaged with the sliding door or window in the vertical direction.

10. A sliding door or window assembly, comprising:
a sliding door or window having an optically switchable device, the sliding door or window configured to slideably engage with a lengthwise slot in a guide;
the guide having a recess within which pass one or more wires in electrical communication with the optically switchable device and with a power source; and
a shuttle configured to couple to the sliding door or window and to slideably engage with the lengthwise slot in the guide, wherein the one or more wires from the sliding door or window pass through a body of the shuttle into the recess of the guide, wherein the shuttle is configured such that during movement of the sliding door or window, the one or more wires are prevented from interaction with one or more moving components.

11. The sliding door or window assembly of claim 10 , wherein the one or more wires are part of a ribbon cable.

12. The sliding door or window assembly of claim 10 , further comprising a flexible member affixed at one end to the shuttle, the one or more wires coupled to the flexible member, wherein the flexible member comprises a bend portion allowing the flexible member to pass back over itself and reside substantially parallel to the length of, and inside, the guide.

13. The sliding door or window assembly of claim 12 , wherein the flexible member is a spring steel tape.

14. The sliding door or window assembly of claim 12 , wherein the flexible member is a chain guide made of a non-electrically conducting material, and the one or more wires reside within the body of the chain guide.

15. The sliding door or window assembly of claim 14 , wherein a vertical portion of the body of the shuttle passes through an aperture in a base plate affixed to the sliding door or window.

16. The sliding door or window assembly of claim 10 , wherein the shuttle is configured to slideably engage with the sliding door or window in the vertical direction.

17. The sliding door or window assembly of claim 10 , wherein the guide further comprises an open end configured such that the shuttle may be inserted into the lengthwise slot through the open end of the guide.
