Abstract

An electrical connector used to make electrical connection to a heating system or to an antenna system on a glazing comprises a substantially planar foot, suitable for soldering, an angled portion, permanently connected to the foot and substantially at right angles to the plane of the foot and a holding portion, connected to the angled portion and suitable for holding a cable, wherein the foot has a substantially circular or oval shape. A glazing comprising such an electrical connector further comprises a sheet of glazing material, an electrical conductor on a surface of the sheet of glazing material and a solder layer between the electrical conductor and the foot wherein the solder layer comprises lead-free solder. The angled portion may be a male portion of a button connector, also known as a snap connector. The holding portion may be a washer soldered or welded to the angled portion.

First claim

The invention claimed is:

1. An electrical connector comprising:
a foot, substantially planar and of a material suitable for soldering;
an angled portion, permanently connected to the foot and substantially at right angles to the plane of the foot;
a washer, connected to the angled portion and suitable for holding a cable, the washer being a flat disc; and
the foot being substantially circular or oval in shape.

2. An electrical connector according to claim 1 , wherein the angled portion is substantially cylindrical in shape.

3. An electrical connector according to claim 2 , wherein the washer is soldered or welded to the angled portion.

4. An electrical connector according to claim 2 , wherein the angled portion further comprises a ledge to define the position of the washer.

5. An electrical connector according to claim 1 , wherein the angled portion is a male portion of a button connector, having a cylindrical conical shape, wherein the part of the angled portion close to the foot is not as wide as the part of the angled portion remote from the foot and the washer is permanently connected to the angled portion.

6. A glazing comprising an electrical connector according to claim 1 , the glazing further comprising:
a sheet of glazing material;
an electrical conductor on a surface of the sheet of glazing material; and
a solder layer between the electrical conductor and the foot of the electrical connector wherein the solder layer comprises lead-free solder.

7. A glazing according to claim 6 , further comprising a cable, wherein the washer is welded to the angled portion and the cable is soldered to the washer.

8. A method of manufacturing a glazing comprising:
providing a sheet of glazing material;
providing an electrical conductor on a surface of the sheet of glazing material; and
fixing an electrical connector according to claim 1 to the electrical conductor by applying a solder layer between the electrical connector and the electrical conductor, wherein the solder layer is lead-free solder.

9. A method of manufacturing a glazing according to claim 8 , wherein a cable is soldered to the washer at the same time as the washer is soldered to the angled portion.

10. An electrical connector comprising:
a foot having a planar shape and being made of a solderable material;
a cylindrical angled portion permanently connected to the foot at a substantially right angle to a plane of the foot, the angled portion being substantially cylindrical in shape; and
a washer connected to the cylindrical angled portion and suitable for holding a cable, the washer having an outer diameter and an inner diameter, the inner diameter of the washer being greater than or equal to an outer diameter of the cylindrical angled portion.

11. An electrical connector according to claim 1 , wherein the washer has a through-hole.

12. An electrical connector comprising:
a foot having a planar shape and being made of a solderable material;
an angled portion permanently connected to the foot at a substantially right angle to a plane of the foot; and
a thin flat plate connected to the angled portion and suitable for holding a cable.

13. An electrical connector according to claim 12 , wherein the thin flat plate has an inner diameter and an outer diameter.

14. An electrical connector according to claim 13 , wherein the inner diameter of the thin flat plate is selected to fit an outer diameter of the angled portion.

15. An electrical connector according to claim 12 , wherein the angled portion comprises a ledge which defines a position of the thin flat plate.

16. An electrical connector according to claim 15 , wherein the thin flat plate is directly above the ledge.

17. An electrical connector according to claim 15 , wherein the thin flat plate rests on the ledge.

18. An electrical connector according to claim 12 , wherein the thin flat plate is soldered or welded to the angled portion.
