Abstract

An integrated glazing unit (IGU) includes a first pane, an electronic laminate that includes an electronic device provided between first and second substrates, a plurality of terminals coupled to the electronic device, and the first substrate being attached to the first pane. The IGU also includes a second pane coupled to the electronic laminated assembly by a spacer, the spacer being recessed with respect to the laminate edge and the second pane edge, forming an interpane volume, R, between the first and second panes. The IGU further includes a gutter having an open face and giving access to an inner volume, Vi. The gutter is positioned within the interpane volume, R, with the open face being recessed from, flush with or extending by less than 10 mm from the second pane edge. The gutter is suitable for receiving the male and/or female electric connector of a cable harness in the inner volume, Vi.

First claim

The invention claimed is:

1. An integrated glazing unit (IGU), comprising: (a) a first pane comprising a first pane edge, extending along a longitudinal axis, X; (b) an electronic laminate comprising: a first substrate, a second substrate, an electronic device provided between the first and second substrate, a plurality of terminals coupled to the electronic device, a laminate edge extending along the longitudinal axis X and being recessed with respect to the first pane edge; and wherein the first substrate is attached to the first pane; (c) a cable harness connected to the terminals and ending with a male or female electric connector; (d) at least a second pane comprising a second pane edge extending along the longitudinal axis, X, and coupled to the electronic laminate by a spacer maintaining a distance between the electronic laminate and the second pane, said spacer being recessed with respect to the laminate edge and the second pane edge, forming an interpane volume, R, between the first and second panes; and (e) a gutter: comprising an open face defined by a length, L, measured parallel to the longitudinal axis, X, a width, W, and a depth, D; said open face extending along the length, L, and giving access to an inner volume, Vi; and being positioned within the interpane volume, R, with the open face being recessed from, flush with or extending by less than 10 mm, wherein the gutter is suitable for receiving the male and/or female electric connector in the inner volume.

2. The integrated glazing unit according to claim 1 , wherein the gutter further comprises a portion of the cable harness.

3. The integrated glazing unit according to claim 1 , wherein the gutter has a polygonal or circular cross-section normal to the longitudinal axis, X.

4. The integrated glazing unit according to claim 3 , wherein the gutter has a rectangular cross-section with beveled edges normal to the longitudinal axis, X.

5. The integrated glazing unit according to claim 1 , wherein the gutter comprises an external surface provided with protrusions and/or recesses.

6. The integrated glazing unit according to claim 1 , wherein the male or female electric connector occupies less than the half of the length, L, of the inner volume, Vi.

7. The integrated glazing unit according to claim 1 , wherein the gutter extends along the longitudinal axis, X, from a proximal end to a distal end wherein the proximal end comprises an opening suitable for allowing the passage of the cable harness.

8. The integrated glazing unit according to claim 1 , wherein the second pane has a length, L2, measured along the longitudinal axis, X, and wherein the length, L, of the inner volume, Vi of the gutter is less than 50% length of the second pane, L2.

9. The integrated glazing unit according to claim 1 , wherein the interpane volume is filled with a sealant material, embedding an external surface of the gutter.

10. The integrated glazing unit according to claim 1 , wherein the electronic laminate further comprises:
a first transparent conductive layer on the first substrate;
a first bus bar applied to the first substrate and the first transparent conductive layer;
an active electronic material layer;
a second transparent conductive layer on the second substrate;
a second bus bar applied to the second substrate and the second transparent conductive layer.

11. The integrated glazing unit according to claim 1 , wherein the laminate edge is step-shaped, at least a portion of the second substrate being recessed relative to at least a portion of the first substrate, exposing at least a portion of the terminals for electric connection.

12. The integrated glazing unit according to claim 11 , wherein the third pane has a same length as the second substrate.

13. The integrated glazing unit according to claim 1 , wherein the electronic device is selected from the group consisting of electrochromic, Suspended Particles Devices, Liquid Crystal Displays, photovoltaic cells, and/or displays.

14. The integrated glazing unit according to claim 13 , wherein the electronic device is an electrochromic device.

15. The integrated glazing unit according to claim 1 , further comprising: i. N number of electronic laminates, with N>1, each comprising: a first substrate, a second substrate, an electronic device provided between the first and second substrate, a plurality of terminals coupled to the electronic device, a laminate edge extending parallel to and recessed with respect to an adjacent edge of the first pane edge; and positioned between the electronic laminate and the second pane, ii. N number of cable harnesses connected to corresponding terminals of the N number of electronic laminates and each ending with a Nth male or female electric connector, and iii. N number of gutters, each gutter comprising an open face defined by a length, L, measured parallel to an adjacent edge of the first pane and suitable for receiving corresponding Nth male or female electric connectors.

16. The integrated glazing unit according to claim 1 , wherein the first pane and second pane are glass sheets.

17. The integrated glazing unit according to claim 16 , wherein the first substrate and second substrate are glass sheets.

18. The integrated glazing unit according to claim 1 , further comprising a third pane, located between the second substrate and the spacer, said third pane comprising a third pane edge recessed with respect to the first pane edge.

19. A method of producing an integrated glazing unit (IGU) according to claim 1 , comprising:
laminating the electronic device to the first substrate and second substrate;
attaching the electronic laminate to the first pane,
attaching the second pane, to the spacer for maintaining a distance between the second pane and the second substrate;
connecting the cable harness to at least a portion of the terminals of the electronic laminate;
positioning the gutter within the interpane volume, R, by pressing the gutter into the sealing material before it has set, such that the gutter is recessed from, flush with or extending by less than 10 mm from the second pane edge;
positioning the electric connector, into the inner volume, Vi; and
filling the interpane volume with a sealing material.

20. The method of producing an integrated glazing unit (IGU) according to claim 19 , further comprising:
partially filling the interpane volume with a sealing material before positioning the gutter within the interpane volume, by pressing the gutter into the sealing material before it has set, such that the gutter is recessed from, flush with or extending by less than from the second pane edge.
