The invention describes an electronics device housing having two side wall elements, which are spaced apart from one another, for forming a housing having a housing interior for accommodating at least one printed circuit board, wherein at least one fitting location for conductor connection plug connectors is provided on at least one of the end faces in the intermediate space between the side wall elements. The electronics device housing has receiving devices in the region of the at least one fitting location, the receiving devices being designed to selectively receive—an ejector element, which can be pivotably mounted on the electronics device housing by the receiving devices, for ejecting a conductor connection plug connector from a fitting location, or—a locking element, which can be fixedly latched to the electronics device housing by of the receiving devices, for locking a conductor connection plug connector at a fitting location.
