Electrical enclosed functional unit

Abstract

Abstract 1. Enclosed electrical switch panel with the features : 1.1 the switch panel is provided with at least one plug-in unit (1) which carries connector elements for complementary connector elements fixedly arranged in the switch panel, and also a pull lever (4) which is pivotable about a horizontal shaft (3) ; 1.2 the pull lever (4) has on one side of the shaft (3) a power arm (4a), which can be swung out from the front of the plug-in unit and back, and on the other side of the shaft (3) a work arm (4b) which is engageable with a recess (5) arranged in a fixed switch panel rail (2), which recess (5) has a front boundary edge (5a) and a rear boundary edge (5b) ; 1.3 by swinging out the power arm (4a) of the pull lever (4), the plug-in unit (1) is movable out of its operating position, as the work arm (4b) acts on the rear boundary edge (5b) of the recess (5) of the switch panel rail (2) ; 1.4 by swinging the power arm (4a) of the pull lever (4) back, the plug-in unit (1) is movable into its operating position, as the work arm (4b) acts on the front boundary edge (5a) of the recess (5) of the switch panel rail (2) ; characterised by the features : 1.5 the power arm (4a) of the pull lever (4) can be prevented from swinging out from the front of the plug-in unit by a bar (7) which, by engagement of a rotary actuator (6) arranged on the plug-in unit (1), can be forced to move into the swing path of the power arm (4a) ; 1.6. the unblocked power arm (4) can swing out freely by itself, under its own weight, from the front of the plug-in unit until the work arm (4b) lies against the rear boundary edge (5b) of the recess (5) of the switch panel rail (2) ; 1.7 when the plug-in unit (1) is out of its operating position, with the actuator (6) engaged, the bar (7) lies in the path of the return swing of the swung out power arm (4a) of the pull lever (4), while the work arm (4b) of the pull lever (4) together with the rear boundary edge (5b) of the recess (5) of the fixed switch panel rail (2) forms a block against movement of the plug-in unit (1) into the operating position.
