Abstract: A ventilation device for electrical control devices is provided in a housing wall of a housing. The ventilation device includes a wall with an inner opening that is open with respect to the space inside the housing and is intended for receiving and delivering a gas from and to the space inside the housing. The wall of the device also includes an outer duct opening that is open with respect to the housing surroundings and is intended for receiving and delivering a gas from and to the housing surroundings. The inner opening and the outer duct opening are connected to each other for leading the gas between the openings through a ventilation duct unit in which a membrane unit is disposed. The inner opening and the outer duct opening are offset laterally with respect to each other such that they do not overlap each other.

Abstract: A plug-in connector is introduced into a mounting hook as far as a stop and pivoted toward a printed circuit board for mounting. Fixation elements thereby lock in holes in the printed circuit board in detent fashion and secure the plug-in connector to the printed circuit board. The plug-in connector can then be soldered in one operation together with remaining SMDs of the printed circuit board.
