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.
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 further connection conductors by contact wires, the optical transmitter, the optical receiver, the contact wires and parts of the separate and further connection conductors being embedded in a primary enveloping body which is embedded in a secondary, nontransparent enveloping body, characterized in that the interface between the primary enveloping body and the secondary enveloping body comprises at least one first zone in which the primary and the secondary enveloping bodies are adhesively interconnected, and in that the interface comprises at least one second zone in which the primary and the secondary enveloping bodies are interconnected non-adhesively.
