A plug-in connector (1), for warm edge hollow profiles (2) of spacers of insulating glazing, has a base with side walls (6) at the edges. A plurality of retaining elements (15) formed as spring lugs are arranged on the outer side of the base (bottom) (5) in a single central row on each of both sides of the center (3) of the plug-in connector (1). Starting from the base (5), the retaining elements are directed obliquely outwards towards the adjacent hollow profile base (28) and towards the connector center (3). The retaining elements (15) are in each case arranged in a sunken base region (13) on the outer side of the base (5) that adjoins a raised, plate-like base region (11) arranged in the region of the center (3). Laterally obliquely outwardly directed resilient retaining elements (18,19) are arranged at the free edge region (7) of the side walls (6).

Embodiments include a window assembly that includes a first sheet of a translucent, transparent or semi-transparent material; a second sheet of a translucent, transparent or semi-transparent material; a spacer extending from the first sheet to the second sheet and includes at least a first elongated strip having a first surface and wherein the spacer defines a muntin opening in the first surface of the first strip; and a muntin bar having a first end that is positioned within the muntin opening of the spacer. Other embodiments are also included herein.

A manufacturing method of a glass panel unit of the present invention includes a bonding step, a pressure reduction step, and a sealing step. In the bonding step, a first substrate and a second substrate are hermetically bonded together with a seal having a frame shape. In the pressure reduction step, a pressure in an inside space formed between the first substrate and the second substrate is reduced through an exhaust port. In the sealing step, sealant melted is dropped toward the exhaust port, thereby sealing the exhaust port with the sealant.

A method and device for assembling an insulating glass panel includes: a TPS station for applying a paste-like TPS strand onto a standing glass sheet edge which includes a horizontal conveyor; a rotation station with a horizontal conveyor rotatable about a vertical axis of rotation; a pressing station for joining two glass sheets that have each been provided with a TPS strand to form the insulating glass panel including two horizontal conveyors running parallel to one another; and a controller for directing two glass sheets that are supplied to the rotation station one after another and each provided with a TPS strand into the pressing station by rotating one of the glass sheets and for joining same in said pressing station to form the insulating glass panel.

A method and device for assembling an insulating glass panel includes: a horizontal conveyor and primer station for applying a strip-like primer along a standing glass sheet edge; a horizontal conveyor and TPS station for applying a paste-like TPS strand, that subsequently solidifies, onto a standing glass sheet edge; a rotation station for rotating glass sheets arranged downstream of the TPS station having a horizontal conveyor rotatable about a vertical axis of rotation; a pressing station for joining the glass sheets together including two parallel horizontal conveyors; and a controller for directing two glass sheets supplied to the rotation station one after another into the pressing station by rotating one of the glass sheets and for joining same in said pressing station to form the insulating glass panel. One glass sheet has a primer strip and TPS strand and the other has a primer strip.

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.
