Abstract
An optical coupler has a radiation transmitter and a radiation receiver with a coupling medium disposed therebetween and surrounded by an enveloping mass. In order to avoid electric disruptive breakdowns in the boundary area between the coupling medium and the enveloping mass, an insulating film is applied on the surface of the conductor bands which carry the radiation transmitter and the radiation receiver, respectively.
Claims10
In a high voltage stable optical coupler of the type wherein a radiation transmitter and a radiation receiver are mounted on respective conductors, a transluscent coupling medium is disposed between the transmitter and the receiver, and a non-transluscent enveloping mass surrounds the coupling medium and has the conductors extending therethrough, the improvement therein comprising:
- a radiation-permeable transluscent insulating film completely covering at
- least one of the conductors.
