Patent ID: 8410462

Claim:
An optoelectronic apparatus for transmission of an electrical signal via, galvanically isolated by means of a one-piece, translucent, plastic body, comprising: an input current circuit, having at least one optical transmission element; and an output current circuit, having at least one optical receiving element, wherein: said optical transmission element has a principle transmission axis of maximum transmission intensity and the optical receiving element has a principle receiving axis of maximum receiving intensity; the principle transmission axis of said optical transmission element and the principle receiving axis of said optical receiving element coincide with a shared optical axis; said plastic body has two cavities separated via a partition for accommodating, respectively, said optical transmission element and said optical receiving element; openings of said two cavities in said plastic body lie on the optical axis; and said transmitting element and/or said receiving element are/is placed through said openings so far into said cavities of said plastic body, that, following a case of overvoltage on said transmitting element and/or said receiving element, an insulating air distance and creep path of said plastic body related to a mounting on a circuit board is still present along the outer surfaces of said plastic body.
