Abstract
The invention relates to an opto-electronic coupler comprising an optical transmitter and an optical receiver which are secured to separate connection conductors and which are electrically connected to one or more connection conductors via contact wires, the transmitter, the receiver, the contact wires and parts of the connection conductors being embedded in a primary, enveloping body, and said primary enveloping body being embedded in a secondary, non-transparent enveloping body. Couplers having a high breakdown voltage and a low percentage of rejects are obtained if the interface between the primary enveloping body and the secondary enveloping body comprises at least one zone in which the primary and the secondary enveloping bodies are adhesively interconnected, and if the interface also comprises at least one zone in which the primary and the secondary enveloping bodies are interconnected in a non-adhesive manner.
