Abstract

A power feeding structure includes a resin plate body for window configured by stacking a resin panel and a resin film including an object to have power fed such that the object to have power fed is interposed between the resin panel and the resin film, and an electrical conductive portion that contacts the object to have power fed and is provided inside the resin plate body for window, the power feeding structure feeding power to the object to have power fed via the electrical conductive portion that is provided at a resin sheet that is provided inside the plate body such that the electrical conductive portion is interposed between the resin sheet and the object to have power fed, the resin panel and the resin sheet being adhered, and resin components contained in the object to have power fed and the electrical conductive portion, respectively, being adhered.

First claim

What is claimed is:

1. A power feeding structure comprising:
a resin plate body for window configured by stacking a resin panel and a resin film at which an object to have power fed is provided such that the object to have power fed is interposed between the resin panel and the resin film, and
an electrical conductive portion that contacts the object to have power fed and is provided inside the resin plate body for window,
the power feeding structure feeding power to the object to have power fed via the electrical conductive portion,
the electrical conductive portion being provided at a resin sheet,
the resin sheet being provided inside the plate body such that the electrical conductive portion is interposed between the resin sheet and the object to have power fed,
the resin panel and the resin sheet being adhered, and
resin components contained in the object to have power fed and the electrical conductive portion, respectively, being adhered with each other.

2. The power feeding structure according to claim 1 ,
wherein the electrical conductive portion is a printed electrical conductor formed at a surface of the resin sheet.

3. The power feeding structure according to claim 1 ,
wherein each of the resin components has a thermoplastic property.

4. The power feeding structure according to claim 1 ,
wherein each of the resin components has a melting point lower than that of a resin material that contacts the object to have power fed or the electrical conductive portion.

5. The power feeding structure according to claim 1 ,
wherein each of the object to have power fed and the electrical conductive portion contains a metal component in addition to the respective resin component, and contains the metal component and the resin component by a weight ratio of
α/β, which is greater than or equal to 7/3 and less than or equal to 19/1, where weight of the metal component is “a” and weight of the resin component is “β”.

6. The power feeding structure according to claim 1 ,
wherein the power feeding structure is provided with a power feeding hole formed from a surface of the plate body to reach the electrical conductive portion.

7. The power feeding structure according to claim 6 , further comprising a power feeding component electrically connected to the object to have power fed via the power feeding hole and the electrical conductive portion.

8. The power feeding structure according to claim 7 ,
wherein the power feeding component is provided at a surface of the plate body at which the power feeding hole is formed via a bracket provided at the plate body.

9. A resin plate body for window comprising the power feeding structure according to claim 1 .

10. A method of manufacturing a resin plate body for window including a power feeding structure, comprising:
a preparing step of preparing a resin film at which an object to have power fed is provided, and a resin sheet at which an electrical conductive portion is provided;
a stacking step of stacking the resin film and the resin sheet such that the electrical conductive portion is interposed between the object to have power fed and the resin sheet;
a setting step of setting the resin film on which the resin sheet is stacked at an injection die;
an injection molding step of injecting molten resin in the injection die; and
a step of forming hole, after the injection molding step, of forming a power feeding hole from a surface of the resin film to reach the electrical conductive portion.

11. The method of manufacturing the resin plate body for window including the power feeding structure according to claim 10 ,
wherein a cut portion for forming the hole in the step of forming hole is formed at the resin film in the preparing step.

12. The method of manufacturing the resin plate body for window including the power feeding structure according to claim 11 ,
wherein the cut portion has an outline width narrower than that of the electrical conductive portion.

13. The method of manufacturing the resin plate body for window including the power feeding structure according to claim 10 ,
wherein an adhesion suppressing member that suppresses adhesion of resin components contained in the electrical conductive portion and the resin film, respectively, in the injection molding step is provided between the electrical conductive portion and the resin film in the stacking step.

14. The method of manufacturing the resin plate body for window including the power feeding structure according to claim 10 , further comprising a providing step of providing a power feeding component so as to be electrically connected to the object to have power fed via the power feeding hole and the electrical conductive portion after the injection molding step.

15. The method of manufacturing the resin plate body for window including the power feeding structure according to claim 10 ,
wherein a bracket is integrally formed with the resin plate body for window that fixes a power feeding component in the injection molding step.
