Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Die einzige Figur zeigt eine Explosivdarstellung der erfindungsgemäßen Baueinheit.An embodiment of the invention is shown in the drawing and explained in more detail in the following description. The single figure shows an exploded view of the assembly according to the invention.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Eine Baueinheit 10 zum Befestigen eines elektrischen Schalters weist ein Gehäuse 11 einer Halterung 12 auf, an dem eine erste Befestigungshälfte 13 angeflanscht ist. Das Gehäuse 11 hat etwa quadratische Form. Die Befestigungshälfte 13 ragt an der oberen und unteren Stirnseite über das Gehäuse 11 hinaus und ist in seinem unteren Bereich so gebogen, daß sie eine Rohrhälfte 15 bildet. Eine zweite Befestigungshälfte 16, die gleich der ersten (13) ausgebildet ist, ist so zur ersten Befestigungshälfte 13 angeordnet, daß die beiden Rohrhälften 15, 15a zusammen ein Rohr bilden. Beide Befestigungshälften 13, 16 weisen je eine mittige Bohrung 17 bzw. 18 auf, die zueinander fluchten. Ferner sind in beiden Befestigungshälften 13, 16 senkrecht unter den Bohrungen 17 bzw. 18 fluchtende Bohrungen 19, 20 ausgebildet. Die Bohrungen 19, 20 dienen zum Befestigen der Halterung 12 mit Hilfe einer Schraube 22 auf einer Vorrichtung, z.B. auf Zugankern oder auf Schienen an pneumatischen Arbeitszylindern. Dabei umgreifen die beiden Rohrhälften 15, 15a den Zuganker, und beide Befestigungshälften 13, 16 werden durch Festziehen der Schraube 22 aneinandergepreßt.A structural unit 10 for fastening an electrical switch has a housing 11 of a holder 12, to which a first fastening half 13 is flanged. The housing 11 has an approximately square shape. The fastening half 13 protrudes on the upper and lower end faces beyond the housing 11 and is bent in its lower region so that it forms a tube half 15. A second fastening half 16, which is identical to the first (13), is arranged in relation to the first fastening half 13 in such a way that the two pipe halves 15, 15a together form a pipe. Both fastening halves 13, 16 each have a central bore 17 or 18, which are aligned with one another. Furthermore, both fastening halves 13, 16 are perpendicular under the bores 17 and 18, respectively aligned holes 19, 20 formed. The bores 19, 20 are used to fasten the bracket 12 with the aid of a screw 22 on a device, for example on tie rods or on rails on pneumatic working cylinders. The two pipe halves 15, 15a grip the tie rod, and both fastening halves 13, 16 are pressed together by tightening the screw 22.

Auf der der ersten Befestigungshälfte 13 abgewandten Seite des Gehäuses 11 ist ein Magnetfeldschalter 23 angeordnet, der etwa die Außenkontur des Gehäuses 11 aufweist. Es ist aber auch jede andere Art eines Schalters denkbar, der zur berührungslosen Signalabgabe dient. Der Magnetfeldschalter 23 weist eine mittige, zu den Bohrungen 17, 18 fluchtende Bohrung 24 und drei elektrische Steckerkontakte 25 auf.A magnetic field switch 23, which has approximately the outer contour of the housing 11, is arranged on the side of the housing 11 facing away from the first fastening half 13. However, any other type of switch is also conceivable which is used for contactless signal delivery. The magnetic field switch 23 has a central bore 24 aligned with the bores 17, 18 and three electrical plug contacts 25.

Mit Hilfe der Steckerkontakte 25 ist der Schalter 23 am Gehäuse 11 ansteckbar. Die Steckerkontakte 25 sind an den Ecken eines gleichseitigen Dreiecks angeordnet. An der Oberseite des Schalters 23 ist eine Leuchtdiode, z.B. eine sogenannte LED-Anzeige angeordnet, mit der z.B. die eingestellte Position abgelesen werden kann. Vorteilhafterweise kann sich aber auch diese Leuchtdiode am Gehäuse 11 selbst befinden. Da die gleiche Leuchtdiode 26 für eine große Anzahl von verschiedenen Schaltern verwendbar ist, braucht somit bei Ausbau des Schalters 23 die Leuchtdiode 26 nicht eigens mit ausgebaut zu werden. Der Schalter 23 selbst kann dadurch besonders kompakt bauen. Ferner ist zwischen dem Gehäuse 11 und dem Schalter 23 eine dünne Dichtungsplatte 27 angeordnet.With the help of the plug contacts 25, the switch 23 can be plugged into the housing 11. The plug contacts 25 are arranged at the corners of an equilateral triangle. On the top of the switch 23 is a light emitting diode, e.g. a so-called LED display is arranged, with which e.g. the set position can be read. However, this light-emitting diode can advantageously also be located on the housing 11 itself. Since the same light-emitting diode 26 can be used for a large number of different switches, the light-emitting diode 26 does not need to be removed when the switch 23 is removed. The switch 23 itself can be particularly compact. Furthermore, a thin sealing plate 27 is arranged between the housing 11 and the switch 23.

An der oberen Stirnseite des Gehäuses 11 befindet sich ein fest angegossener Kabelanschluß 29 mit einem elektrischen Kabel 30, das z.B. zu einem nicht dargestellten Verteilerkasten führt. Der Kabelanschluß 29 kann selbstverständlich auch an einer anderen Seite des Gehäuses 11 angeordnet sein. Die Teile Schalter 23, Gehäuse 11 und die beiden Befestigungshälften 13, 16 sind mit Hilfe einer in die Bohrungen 17, 18, 24 einschraubbaren Schraube 31 aneinander befestigt. Die Halterung 12 ist mit Hilfe der Schraube 22 auf der Vorrichtung befestigt, falls die Schraube 31 gelöst wird, um den Schalter 23 auszutauschen. Ferner ist auch der Kabelanschluß 29 fest am Gehäuse 11 angeordnet, so daß der Schalter 23 austauschbar ist, ohne daß das elektrische Kabel 30 bis zum Verteilerkasten ausgebaut werden muß. Dadurch ist der Austausch des Schalters 23 selbst und seine Wartung besonders einfach.On the upper end face of the housing 11 there is a firmly cast-on cable connection 29 with an electrical cable 30, which leads, for example, to a distribution box (not shown). The cable connection 29 can of course can also be arranged on another side of the housing 11. The parts switch 23, housing 11 and the two fastening halves 13, 16 are fastened to one another with the aid of a screw 31 which can be screwed into the bores 17, 18, 24. The bracket 12 is attached to the device by means of the screw 22 if the screw 31 is loosened to replace the switch 23. Furthermore, the cable connection 29 is also fixedly arranged on the housing 11, so that the switch 23 can be replaced without the electrical cable 30 having to be removed as far as the distribution box. This makes the replacement of the switch 23 itself and its maintenance particularly easy.
