Spacers and connectors for insulated glass units
First Claim
1. An insulated glass unit (IGU) comprising:
- a first glass substrate;
a second glass substrate oriented parallel to the first glass substrate;
an electrochromic device positioned on the first or second glass substrates;
two bus bars electrically connected to the electrochromic device;
a spacer positioned between the first and second glass substrates proximate the periphery of the first and second glass substrates, wherein the spacer defines an interior region of the IGU located interior of the spacer and an exterior region of the IGU located outside of the spacer; and
one or more wires passing through the spacer to provide electrical power from an external power source located in the exterior region to the bus bars and the electrochromic device in the interior region of the IGU.

Abstract
This disclosure describes insulated glass units (IGUs) that incorporate electrochromic devices. More specifically, this disclosure focuses on different configurations available for providing an electrical connection to the interior region of an IGU. In many cases, an IGU includes two panes separated by a spacer. The spacer defines an interior region of the IGU and an exterior region of the IGU. Often, the electrochromic device positioned on the pane does not extend past the spacer, and some electrical connection must be provided to supply power from the exterior of the IGU to the electrochromic device on the interior of the IGU. In some embodiments, the spacer includes one or more holes (e.g, channels, mouse holes, other holes, etc.) through which an electrical connection (e.g., wires, busbar leads, etc.) may pass to provide power to the electrochromic device.
