Description
Schutzkappe für elektrische Geräte, insbesondere für Relais Die Erfindung betrifft eine Schutzkappe für elektrische Geräte, insbesondere für Relais. Bekannte Schutzkappen dieser Art sind gegen unzulässiges Abziehen durch eine meist an der Stirnseite angeordnete Schraube bzw. Mutter gesichert. Nachteilig bei einer derartigen Ausführung ist, daß die Kappe auch dann entfernt werden kann, wenn das Relais unter Spannung steht.Protective cap for electrical devices, in particular for relays The invention relates to a protective cap for electrical devices, in particular for relays. Acquaintance Protective caps of this type are against unauthorized removal by a mostly on the Screw or nut arranged on the front side secured. Disadvantage of such The design is that the cap can be removed even if the relay is under There is tension.
Weiterhin sind auch schon Einrichtungen bekannt, bei denen die Schutzkappen erst abgenommen werden können, nachdem das Gerät aus der Steckfassung entfernt und damit stromlos wurde.Furthermore, devices are already known in which the protective caps can only be removed after the device has been removed from the socket and so that it was de-energized.
Nachteilig bei diesen Einrichtungen ist, daß sie infolge Verwendung zusätzlicher, nur der Verriegelung dienender Teile nicht nur in ihrem Aufbau sehr aufwendig sind; es ist vielmehr zur Verriegelung noch manuell ein Schieber zu betätigen.The disadvantage of these devices is that they are used as a result additional parts that are only used for locking, not only in terms of their structure are expensive; rather, a slide has to be operated manually for locking.
Diese Nachteile werden durch die Kappe gemäß der Erfindung dadurch verrnieden, daß außer der Kappe und Grundplatte keine weiteren Teile benötigt werden und die Verriegelung automatisch nur durch Aufsetzen der Kappe erfolgt.These drawbacks are thereby made by the cap according to the invention Avoid the need for other parts than the cap and base plate and locking takes place automatically only by putting on the cap.
Die Anordnung ist dabei so getroffen, daß die an der offenen Seite der Kappe vorgesehenen Laschen mit je einem Fenster versehen sind, in das jeweils eine an einer Messerplatte angeordnete Nase eingreift und die Laschen selbst bis nach der Trennung der Messerkontakte in den in der Buchsenplatte angeordneten Schlitzen geführt sind. Die Laschen sind demzufolge in ihrer Länge so dimensioniert, daß ihr Führungsgang in den Schlitzen der Buchsenplatte den wirksamen Kontaktweg übertrifft. Dadurch wird erreicht, daß die Arretierung der Kappe erst nach der Kontakttrennung aufgehoben werden kann.The arrangement is such that the tabs provided on the open side of the cap are each provided with a window into which a nose arranged on a knife tip engages and the tabs themselves until after the blade contacts have been separated in the ones arranged in the socket plate Slots are guided. The length of the lugs is accordingly dimensioned in such a way that their guide path in the slots of the socket plate exceeds the effective contact path. This ensures that the locking of the cap can only be released after the contact has been separated.
Ein Ausführungsbeispiel ist in der Zeichnung perspektivisch dargestellt. Darin bedeutet 1 die Kappe, 2 die Messerplatte, 3 die Buchsenplatte, 4 die Laschen, 5 die Fenster, 6 die Nasen und 7 die Arretierschlitze.An exemplary embodiment is shown in perspective in the drawing. 1 means the cap, 2 the knife plate, 3 the socket plate, 4 the tabs, 5 the window, 6 the lugs and 7 the locking slots.
An der Messerplatte 2 sind außer dem Relais und den Messem die Nasen 6 angeordnet. Die Arretierschlitze 7 befinden sich in der Buchsenplatte 3. Beim Aufsetzen der Kappe 1 auf die Messerplatte 2 gleiten die Laschen 4 über die Nasen 6. Durch das Züisammenwirken von Nasen und Fenstern wird die Kappe arretiert. Beide Teile, Messerplatte mit Kappe, sind nunmehr auf die Buchensplatte zu stecken. Die Laschen werden dabei in die Schlitze 7 eingeführt und sind so lang gehalten, daß eine Verbindung zwischen Messer und Buchsen erst nach Eintritt der Laschen in die Schlitze erfolgt. Durch diese Anordnung sind die Laschen so fixiert, daß die Kappe vom Relais erst nach der Trennung von Buchsenplatte-Messerplatte abgezogen werden kann, so daß die Einzelteile des Relais nur bei Stromlosigkeit zugänglich sind. Die Anwendung des Erfindungsgedankens ist nicht auf das Ausführungsbeispiel beschränkt, vielmehr ist auch eine übertragung auf Geräte ähnlicher Art ohne weiteres möglich.In addition to the relay and the blades, the noses 6 are arranged on the cutter plate 2. The locking slots 7 are located in the socket plate 3. When the cap 1 is placed on the cutter plate 2, the tabs 4 slide over the lugs 6. The cap is locked by the interaction of lugs and windows. Both parts, the knife plate with the cap, are now to be placed on the beech plate. The tabs are inserted into the slots 7 and are kept so long that a connection between the knife and the bushing only takes place after the tabs have entered the slots. With this arrangement, the tabs are fixed in such a way that the cap can only be removed from the relay after the socket plate-cutter plate has been separated, so that the individual parts of the relay are only accessible when there is no current. The application of the inventive concept is not restricted to the exemplary embodiment, rather a transfer to devices of a similar type is also readily possible.
