The present invention relates to an electrical device for rail mounting. Such electrical devices are mounted in use in a side-by-side relationship on a carrier rail. An electrical device for rail mounting comprises a housing having a rail receiving recess therein, at least one edge of said recess being defined by an end region of a latch member that is movable relative to the housing in a direction transverse to the recess, and resilient means biasing the latch member to move in a direction to reduce the width of said recess. Said resilient means comprise a torsion spring having a first leg and a second leg deflectable around a hinge region, said first leg resting against a protrusion of the housing, and said second leg resting against the latch member.

Electrical device for rail mounting

A plug-in power supply for supplying a consumer with a low voltage and a plug-in power supply which in operation is configured as a power adapter unit with one of its matching interchangeable mains plug units. The power adapter unit comprises a housing; a voltage transformer module for converting a mains voltage into the required low voltage in the housing; an engaging seat, for the plug unit, at an inner side of the power adapter unit to be directed towards a mains socket, the plug unit being slidably connected with the engaging seat; at least two electric contacts in the seat connecting the transformer module with contacts at an inner side of the plug unit directed towards the power adapter unit; and a locking member, at a rear profile of the engaging seat which limits the sliding of the plug unit. The plug unit comprises at least two mains plug pins, extending from an outer side of the plug unit and connected to the contacts at the inner side of the plug unit; safety recesses, for said contacts at the inner side of the plug unit; and a locking structure, comprising a button, for interacting with the locking member so that pressing on the button releases the structure and allows sliding of the plug unit from the engaging seat.
