Applications

The present invention relates to an electrical device with heating properties comprising at least two plastics of different electrical conductivity, a first plastic material and a second plastic material, joined by means of joining, so that by applying a electric current to the device, the first plastic material, of greater conductivity than the second plastic material, acts as a contact electrode, allowing a correct distribution of the electric current through the second plastic material, of lower conductivity, which acts as a heating zone. The main objective of the present invention is therefore to solve the problem existing when making electrical contacts in conductive plastic parts. These parts would be used as heating devices. La presente invención se refiere a un dispositivo eléctrico con propiedades calefactoras que comprende, al menos, dos plásticos de distinta conductividad eléctrica, un primer material plástico y un segundo material plástico, unidos mediante unos medios de unión, de forma que mediante la aplicación de una corriente eléctrica al dispositivo, el primer material plástico, de mayor conductividad que el segundo material plástico, actúa como electrodo de contacto, permitiendo una correcta distribución de la corriente eléctrica a través del segundo material plástico, de menor conductividad, que actúa como zona calefactora. El objetivo principal de la presente invención es por tanto solventar la problemática existente a la hora de realizar contactos eléctricos en piezas plásticas conductoras. Dichas piezas se emplearían como dispositivos calefactores.
