The complexity of modern automotive glazing is increasing as more and more technology is being integrated with the glazing. As the industry moves towards full autonomous electric vehicles and as consumers demand increased levels of comfort, convenience, and safety this trend will only increase. It is now common to have electrical components embedded within laminated glazing. However, making electrical connections to embedded components can be challenging. The flexible circuit of the disclosure, which can provide an electrical connection to multiple complex circuits, comprises a flexible circuit with at least one insulating layer, at least one conductive layer and with at least one sharp fold in the flexible circuit. This approach substantially reduces the quantity of material that is wasted, facilitates assembly of the laminate, and reduces cost.
A flexible electrical circuit configured to be embedded into a laminated glazing for a vehicle, comprising:
The flexible electrical circuit of the preceding claim, having at least a portion configured to provide a folded area with a crease such as to obtain two segments on each side of the crease that change directions.
The flexible electrical circuit of any of the preceding claims, wherein the total thickness of the flexible electrical circuit comprising all of the at least one insulating and the at least one conductive layers is equal to or above 25 μm and equal to or less than 1000 μm.
The flexible electrical circuit of any of the preceding claims, wherein the thickness of the at least one sharp fold crease is reduced when compared to the total thickness of the portion immediately adjacent which comprises all of the at least one insulating and at least one conductive layers.
The flexible electrical circuit of any of the preceding claims, wherein the radius of the at least one sharp fold is less than or equal to the thickness of the flexible circuit.
The flexible electrical circuit of any of the preceding claims, wherein the total thickness in the folded area is less than double the total thickness of the portion immediately adjacent which comprises all of the of the at least one insulating and at least one conductive layers.
The flexible electrical circuit of any of the preceding claims, wherein a portion of at least one insulating layer is removed in the folded area.
The flexible electrical circuit of any of the preceding claims, wherein a portion of at least one of the at least one insulating layer is removed following the crease line in such a way that on one side of the crease the insulating layer is present and on the other side of the crease the insulating layer is partially removed.
The flexible electrical circuit of any of the preceding claims, wherein the total thickness in the folded area is less than one and one half the total thickness of the portion immediately adjacent that comprises all of the of the at least one insulating and at least one conductive layer.
The flexible electrical circuit of any of the preceding claims, wherein the total thickness in the folded area is substantially the same or less than that of the total thickness of the portion immediately adjacent that comprises all of the of the at least one insulating and at least one conductive layer.
The flexible electrical circuit of any of the preceding claims, wherein the width of the at least one conductive layer is increased in the folded area.
The flexible electrical circuit of any of the preceding claims, wherein the at least one conductive layer is comprised of copper.
A laminated glazing, comprising:
