Electromagnet for activation of e.g. metering pumps, has bobbin whose plastic portion is constructed from two plastic materials, where one of materials comprises specific value of high surface resistance

The electromagnet (1) has pins (6) provided with bobbins (3), where a plastic portion of the bobbin is constructed from two different plastic materials moldable by casting or injection molding. One of plastic materials comprises thermal conductivity greater than 0.5 W/mK, and the other plastic mater...

description The electromagnet (1) has pins (6) provided with bobbins (3), where a plastic portion of the bobbin is constructed from two different plastic materials moldable by casting or injection molding. One of plastic materials comprises thermal conductivity greater than 0.5 W/mK, and the other plastic material is made of polymers having electrical conductivity of less than 0.01 / (m.Omega) and specific value of high surface resistance. A longitudinal slot is filled by a portion consisting of different plastic materials with low electrical conductivity. An independent claim is also included for a method for producing a bobbin of an electromagnet. Aufgabe: In einem Elektromagneten soll die Leitung der Wärme von der Spule an die Anflanschfläche verbessert werden. Lösung: Das Kunststoffteil des Spulenkörpers (3) ist aus mindestens zwei Bestandteilen aufgebaut, die aus mindestens zwei verschiedenen, durch Spritzgießen formbaren Kunststoffen bestehen, einem ersten Kunststoff mit einer Wärmeleitfähigkeit von mehr als 0,5 W/(m·K) und einem zweiten und gegebenenfalls weiteren Kunststoffen mit einer elektrischen Leitfähigkeit von weniger als 0,01/(m· ). Anwendung: Elektromagnet zur Ansteuerung von Ventilen oder Dosierpumpen.
