Abstract

Das Relais besitzt ein Innengehäuse (1) und ein Außengehäuse (4,5), wobei Innenanschlüsse (3) mit Außenanschlüssen (7) über Litzen (8) verbunden sind. In dem Zwischenraum zwischen dem Innengehäuse (1) und dem Außengehäuse (4,5) ist eine zusätzliche Zwischenkappe (10) aus Elastomer über das Innengehäuse mit den Litzen gesteckt. Zusammen mit einem Dämpfungsrahmen (9) und einer Dämpfungsplatte (13) bewirkt die Zwischenkappe eine Schallentkopplung des Relais von der Außenseite.

Figure 00000001
The relay has an inner housing (1) and an outer housing (4,5), whereby inner connections (3) are connected to outer connections (7) via strands (8). In the space between the inner housing (1) and the outer housing (4,5), an additional intermediate cap (10) made of elastomer is placed over the inner housing with the strands. Together with a damping frame (9) and a damping plate (13), the intermediate cap effects a sound decoupling of the relay from the outside.
