Description

Bei der Durchführung der Betätigungsorgane gekapselter Schalter durch die Gehäuse mittels Schraubköpfen muß bei Serienherstellung die Bedingung erfüllt werden, daB der fest eingeschraubte Schraubkopf bei allen Stücken relativ zum Gehäuse die gleiche Stellung einnimmt. Da sich die Gewinde der Schraubköpfe und die Muttergewinde im Gehäuse in der Serienfertigung nicht in wirtschaftlich vertretbarer Weise so genau herstellen lassen, daß die eingeschraubten Köpfe in allen Fällen die gleiche relative Stellung zum Gehäuse besitzen, hat man sich bisher so geholfen, daB man zwischen Schraubkopf und Gehäuse einen Ausgleichring einlegte. Es mußte dabei für jedes einzelne Stück der passende Ausgleichring ausgesucht werden. Man hat auch Dichtungsringe aus nachgiebigem Material eingelegt, die aber im Laufe der Zeit ein Nachziehen des Schraubkopfes erforderlich machten, wodurch der Schraubkopf eine falsche relative Stellung zum Gehäuse erhielt.When carrying out the actuators encapsulated switch by the housing by means of screw heads must meet the condition in series production that the screwed-in screw head is relative to the housing for all pieces occupies the same position. Since the threads of the screw heads and the nut threads in the housing in series production not in an economically justifiable manner let manufacture exactly that the screwed-in heads are the same in all cases have a relative position to the housing, one has so far helped oneself in such a way that one inserted a compensating ring between the screw head and the housing. It had to be for every single piece of the matching compensation ring can be selected. One also has Sealing rings made of resilient material are inserted, but over time they change Tightening of the screw head made it necessary, whereby the screw head a received incorrect position relative to the housing.

Die Erfindung beseitigt diese Nachteile durch eine Spannkappe über dem Schraubkopf, die sich auf dem Gehäuse abstützt und durch eine Spannschraube mit dem Schraubkopf verbunden ist. Durch Anziehen der Spannschraube läBt sich der Schraubkopf in jeder relativen Stellung zum Gehäuse unveränderlich feststellen.The invention eliminates these disadvantages by using a clamping cap the screw head, which is supported on the housing, and a clamping screw is connected to the screw head. By tightening the clamping screw, the Fix the screw head invariably in every position relative to the housing.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgedankens dargestellt. Sie zeigt teilweise im Schnitt den Schraubkopf zur Durchführung des Betätigungsorgans eines in einem Gehäuse gekapselt eingebauten Schalters. Als Beispiel eines Betätigungsorgans ist eine Zugvorrichtung gewählt, bei welcher der Schraubkopf in jedem Falle diejenige Stellung haben soll, in welcher die Zugstange eine Vertikallage einnimmt.In the drawing is an embodiment of the inventive concept shown. It shows partially in section the screw head for performing the Actuating member of a switch encapsulated in a housing. As an an example of an actuator, a pulling device is selected in which the screw head in each case that position should have in which the tie rod is in a vertical position occupies.

Der zylindrische Schraubkopf i ist in einem Gehäusestutzena eingeschraubt. Über den Schraubkopf ist eine Kappe 3 geschoben, die sich auf dem Gehäusestutzen abstützt und mit der Spannschraube 4 mit dem Schraubkopf verschraubt ist. Die Spannschraube wird bei der gewünschten Stellung des Schraubkopfes festgezogen, im vorliegenden Falle bei der tiefsten Stellung des Schlitzes 5 in der Kappe,. durch welchen die Zugstange 6 mit der Zugkette 7 hindurchgeführt ist.The cylindrical screw head i is screwed into a housing socket a. A cap 3 is pushed over the screw head and is located on the housing socket and is screwed to the screw head with the clamping screw 4. The turnbuckle is tightened at the desired position of the screw head, in this case Fall at the lowest position of the slot 5 in the cap. through which the Pull rod 6 with pull chain 7 is passed through.

Selbstverständlich kann der Schraubkopf mittels der Spannschraube auch in jeder anderen Stellung festgehalten werden.Of course, the screw head can by means of the clamping screw can also be held in any other position.
