Abstract:
The invention relates to a photocoupler comprising a light emitting element and a light receiving element, the light emitting element having a first and a second electrode in electrical contact with a first and a second contact pin, respectively, by means of which the light emitting element is fixed in position, the light receiving element having a third and a fourth electrode in electrical contact with a third and a fourth contact pin, respectively, by means of which the light receiving element is fixed in position. The light emitting element and the light receiving element are situated opposite one another and enveloped in a first solid and transparent layer, surrounded at least in part by a second solid layer provided in such a manner as to reflect the light. According to the invention, a pre-formed housing has a bottom and side walls, the bottom having at least one cavity which accommodates a first end of the first, second, third and fourth pin and a first, second, third and fourth slot in which central portions of the first, second, third and fourth pins, respectively, are held.
