Description

Bei Durchführungsisolatoren, deren Mittelteil um die kragenförmige Metallfassung herumgegossen oder -gepreßt wird, kommt es vor, daß sich im Betrieb die Fassung gegenüber dem sie umgebenden Isolierstoff etwas lockert; es entstehen dann Hohlräume und in ihnen Glimmfunken, die den Stoff örtlich erwärmen und zu Zerstörungen führen können. Man hat daher vorgeschlagen, die Fassung elastisch zu machen, damit sie den Formänderungen und dem Schwunde des Isolierstoffs besser zu folgen vermag.With bushing insulators, the middle part around the collar-shaped metal socket is poured or pressed around, it happens that the version is opposite during operation the surrounding insulating material loosens somewhat; there are then cavities and in them glow sparks that heat up the material locally and can lead to destruction. It has therefore been proposed to make the socket elastic so that it can withstand changes in shape and is able to better follow the shrinkage of the insulating material.

Dies wird nach der vorliegenden Erfindung dadurch erreicht, daß man die Fassung aus zwei Blechen mit umgebördeltem Rand zusammensetzt, die so aufeinanderliegen, daß die beiden Blechränder nach entgegengesetzten Seiten gerichtet sind.This is achieved according to the present invention in that one of the socket composed of two sheets with a flanged edge, which lie on top of one another so that the two sheet metal edges are directed towards opposite sides.

Ein Isolator, wie er nach der Erfindung beispielsweise ausgeführt werden kann, ist in Abb. ι der Zeichnung dargestellt. Sein Isolierkörper α besteht aus Preßnlaase, z. B. künstlichem Harz und einem Füllstoff, und die Fassung \, b„, c ist in den Isolierstoff eingepreßt. Sie besteht erfindungsgemäß aus zwei mit ihren aufgebördelten Innenrändern voneinander abgewandten Blechischeiben &x und b2, deren Elastizität durch eine Gummizwischenlage c erhöht ist. Eine weitere Erhöhung der Elastizität der Fassungsbleche läßt sich durch besondere Ausbildung derselben erzielen, beispielsweise durch radiale Einschnitte d, wie sie in Abb. 2 angedeutet sind.An insulator, as it can be carried out according to the invention, for example, is shown in Fig. Ι of the drawing. Its insulating body α consists of Preßnlaase, z. B. artificial resin and a filler, and the version \, b ", c is pressed into the insulating material. According to the invention, it consists of two sheet metal disks & x and b 2 facing away from one another with their flared inner edges, the elasticity of which is increased by an intermediate rubber layer c . A further increase in the elasticity of the mounting plates can be achieved through a special design of the same, for example through radial incisions d, as indicated in FIG.
