Background technique

Such electrical installation switchgear, for example line protective switches or fault current protective switches (Fehlerstromschutzschalter), are integrated into electrical installation distribution systems (Installationsverteilung), where they are snapped onto standard profile support rails Especially on hat-shaped support rails. Such hat-shaped support rails have a U-shape, wherein at the free ends of the feet (Schenkel) there are molded (anformen) flanges (vorspringende) protruding in the opposite direction, the free longitudinal edges of which act as Fixing edge for electrical installation switchgear.

In particular, the circuit breaker has on its fastening side, ie on the side with which the circuit breaker is fastened on such a hat-shaped support rail, a recess which is often U-shaped, On one of its inner walls a stationary shoulder protrudes into the groove and on its other inner wall a movable shoulder protrudes into the groove.

The hat-shaped support rail is arranged in the installation distribution system in such a way that the plane spanned or formed by the flange is oriented vertically, wherein the longitudinal edges of the hat-shaped support rail run horizontally. In order to fasten the circuit breaker on the cap-shaped support rail, the circuit breaker is hung with its stationary shoulder behind the upper edge of the cap-shaped support rail, and then by swiveling against the cap-shaped support rail, through It is fixed or fastened or locked (aufgerastet) in such a way that the movable shoulder is pressed apart by the lower hat-shaped support rail until the movable shoulder snaps onto the lower edge of the hat-shaped support rail. side behind. Naturally, the same applies to other installations which are integrated into distribution systems, switch cabinets or the like.

Usually, the movable shoulder is molded on the slide, which is pressed into the interior of the groove on the fixed side by means of a spring. Numerous solutions exist for this.

Document DE 198 36 890 A1 shows an electrical installation switchgear with a housing and with snap-fastening means for snapping the installation switchgear onto a hat-shaped support rail, with at least one A movable stop shoulder, which engages behind the longitudinal edge of the hat-shaped support rail in the state of being clamped on the hat-shaped support rail, wherein the movable shoulder is fixed at the slider, wherein, The slider carries a detent for locking and unlocking the slider with the housing. The slider is made of elastic (fedemdem) material and has two parallel outer arms (Auβenarme) with outer shoulders protruding perpendicular to the slider and an elastic middle arm (Auβenarme) in between. With a central shoulder that also protrudes perpendicularly to the slide), the shoulder surface of the central shoulder occupies a greater distance from the plane spanned by the outer arm in the relaxed state than the shoulder surface of the outer shoulder. The distance is small, so that in the installed state the central shoulder assumes support on the hat-shaped support rail. Therefore, although the lifting of the mounting device can be realized for dismounting, wherein the elastic middle shoulder has allowed the lifting of the shoulder surfaces up to the two outer shoulders, thus, the movement of the mounting device can be done without tools. Dismantling is possible in this case and enables the removal of the installation switching devices from combinations of installation switching devices which are arranged in a row with one another in the case of an existing cross-wiring. However, the engagement of the installation switching device on the hat-shaped support rail is not very firm, so that, for example, twisting of the installed installation switching device on the hat-shaped support rail is possible, which is undesirable.
