Connector for joining multiple pane window spacers

Abstract

A connector key for joining spacer member ends in multi-pane window units. A connector key and methods for joining spacer member ends are provided. The connector key can include a top central depression, side walls having top gaps, side shoulders having channels and recesses, all providing opportunity for sealant to flow from the central depression over the side regions of the connector key. Connector keys can also have holes through the bottom floor of the central depression to the bottom of a connector key and further through bottom channels provided in the connector key. Methods are provided which include sliding a spacer member over each end of the connector key up to a central flange. Holes may be punched through the spacer material, preferably forming jagged portions which secure the spacer members to the connecting key. Sealant may be injected through the punched holes, and through the through holes in the connector key central depression floor. Injected sealant may thus flow into the central depression, over the side walls into the side recesses, and into the bottom channels. The connector key can provide temporary mechanical joinder while the sealant is curing, as well as mechanical rigidity and insulative gas sealing after curing.
