Abstract

Electrical elements are moulded from a material having a high filler content. The mould contg. the components is filled with a granular filler and has the liq. moulding material added under high vacuum. A material with strong adsorption props. in gases and steam, pref. molecular sieve or silica gel, is added to the filler.

Description

Verfahren zum Vergießen elektrischer Bauteile mit einer Vergußmasse hohen Füllstoffgehalts Zusatz zu Patent . ... ... (Patentanm. P 17 04 302.6) Das Hauptpatent betrifft ein Verfahren zum Vergießen elektrischer Bauteile mit einer Vergußmasse hohen Füllstoffgehalts, bei dem in die Vergußform mit dem darin befindzeichen Bauteil mit körnigem FullstoÎf dicht gefüllt und unter Hochvakuum die flüssige Vergußmasse eingefüllt wird.Method for potting electrical components with a potting compound high filler additive to patent. ... ... (Patent application P 17 04 302.6) Das The main patent relates to a method for potting electrical components with a Potting compound with a high filler content, in which in the casting mold with the symbol in it Component tightly filled with granular filler and the liquid potting compound under high vacuum is filled.

Dabei kann der Füllstoff unterschiedlicher Körnung bzw.The filler can be of different grain size or

unterschiedliche Füllstoffe verwendet werden.different fillers can be used.

Beim Vergießen elektrischer Bauteile ist es im Hinblick auf die elektrische Isolation erforderlich, Einschlüsse von Gasen oder Dämpfen des Lösungsmittels in der erstarrenden Vergußmasse so weit wie möglich zu vermeiden. Bei dem Vergießen der Bauteile unter Hochvakuum wird dieser Forderung weitgehend Rechnung getragen Um eine praktisch restlose Entgasung su erreichen, läßt sich das Verfahren nach dem Hauptpatent dahingehend vorteilhaft erweitern, daß dem Füllstoff ein Material mit starkem Adsorptionsvermögen für Gase und Dämpfe zugefügt wird.When potting electrical components it is electrical with regard to it Isolation required, inclusions of gases or vapors in the solvent to avoid solidifying potting compound as much as possible. During the shedding of the components under high vacuum, this requirement is largely taken into account In order to achieve practically complete degassing, the process can be followed the main patent to the effect that the filler is a material with strong adsorption capacity for gases and vapors is added.

Als besonders geeignet haben sich dazu Alkali- oder Brdalkalimetal1-Aluminiumsilikate, sogenannte Molekularsiebe oder Kieselsäuregel erwiesen.Alkali metal or alkaline metal aluminum silicates have been found to be particularly suitable for this purpose, so-called molecular sieves or silica gel proved.
