Description
Elektrischer Drehschalter, bei dem durch Nocken gesteuerte Kontakthebel in Längsrichtung der Schalterachse angeordnet sind Die Erfindung besteht in einer Weiterbildung des Gegenstandes des Patents 855 28o, bei dem durch Nocken gesteuerte Kontakthebel oder Kontaktfedern in Längsrichtung der Schalterachse angeordnet sind. Die Erfindung gegenüber dem Hauptpatent besteht darin, daß ein feststehender Isolierstoffkern innerhalb der um die Schalterachse herum angeordneten Kontakthebel oder Kontaktfedern als Träger der Verbindungskontakte und zur Lagerung der Schalterachse dient. An den beiden Stirnseiten des Isolierstoffkernes sind mit der Schalterachse unverdrehbar verbundene Nockenscheiben vorhanden, durch welche die Kontakte der Kontakthebel bzw. der Kontaktfedern von den Kontakten bzw. Kontaktbrücken des Isolierstoffkernes abgehoben werden. Der Isolierstoffkern besteht mit dem die Anschlußklemmen tragenden Sockel aus einem Stück und wird z. T. durch die Nischen gebildet, in welchen die Kontakthebel bzw. Kontaktfedern angeordnet sind und sich bewegen.Electrical rotary switch with contact lever controlled by cams are arranged in the longitudinal direction of the switch axis Further development of the subject matter of the patent 855 28o, in which controlled by cams Contact levers or contact springs are arranged in the longitudinal direction of the switch axis. The invention over the main patent is that a fixed insulating core within the contact levers or contact springs arranged around the switch axis serves as a carrier for the connection contacts and for mounting the switch axis. At the two end faces of the insulating core cannot be rotated with the switch axis connected cam disks through which the contacts of the contact lever or the contact springs from the contacts or contact bridges of the insulating material core be lifted off. The insulating core is made with the one carrying the terminals One-piece base and is z. T. formed by the niches in which the Contact levers or contact springs are arranged and move.
Der Erfindungsgegenstand besitzt noch weitere Merkmale, wie z. B. die Anordnung der Nockenscheiben in besonderen Versenken des Sockels, deren Bodenflächen die Stirnflächen des Isolierstoffkernes bilden, oder die Anordnung der ortsfesten Kontaktbrücken in Rillen der vorgenannten Versenke bzw. die Sperrung der Steuernocken durch axial gerichtete Sperrnocken in den Stirnflächen des Isolierstofikernes.The subject of the invention also has other features, such as. B. the arrangement of the cam disks in special countersinking of the base, their bottom surfaces form the end faces of the insulating core, or the arrangement of the stationary Contact bridges in the grooves of the aforementioned sinks or the blocking of the control cam by axially directed locking cams in the end faces of the insulating core.
Ein besonderes Merkmal sind noch die Durchbrüche von den Nischen zu dem unteren Versenk durch den Boden desselben, so daß die in den Kischen angeordneten Kontaktfedern durch die Durchbrüche hindurchtreten und von der unteren Nockenscheibe gesteuert werden.The breakthroughs from the niches are a special feature the lower recess through the floor of the same, so that those in the niches arranged Contact springs pass through the openings and from the lower cam disk being controlled.
Der neue Schalter ist in Abb-: i in einem Schnitt und in Abb. 2 in einer Draufsicht dargestellt; Abb.3 zeigt einen Längsschnitt durch den Schaltersockel, aus dem die Verbindung des Isolierstoffkernes mit dem Sockel hervorgeht.The new switch is shown in Fig-: i in a section and in Fig. 2 in shown in a plan view; Fig.3 shows a longitudinal section through the switch base, from which the connection of the insulating core with the base emerges.
Der Isolierstoffkern i ist in dem Raum, den die Kontakthebel bzw. Kontaktfedern 2, 3, 4 und 5 einschließen, angeordnet. Er dient einerseits den beiden Kontaktringen 6 und 7 als Träger und anderseits der Schalterachse 8 als Lager. An den beiden Stirnseiten des Isolierstoffkernes sind die beiden Nockenscheiben 9 und io in besonderen Ausnehmungen des Sockels z i angeordnet. - Die Bodenfläche 12 und 13 (Abb. 3) der beiden Versenke bilden gleichzeitig die Stirnflächen des Isolierstoffkernes i. Die beiden Nockenscheiben 9 und io sind mit der Schalterachse 8 unverdrehbar verbunden. Sie heben die Kontakte 14, 15 der Kontakthebel bzw. Federn 2, 3, 4 und 5 je nach der Schaltaufgabe von den ortsfesten Kontakten 6 und 7 des Isolierstoffkernes i ab, wobei die Ablenkung an den über die Kontakte 14, 15 hinausragenden Enden der Hebel bzw. Federn erfolgt. Die von der unteren Nockenscheibe gesteuerten Kontaktfedern treten dabei durch die zwischen den Nischen und dem unteren Versenk angeordneten Durchbrüche 18 (Abb. i und 3).The insulating core i is in the space that the contact lever or Include contact springs 2, 3, 4 and 5, arranged. On the one hand, it serves both of them Contact rings 6 and 7 as a carrier and on the other hand the switch axis 8 as a bearing. At the two end faces of the insulating material core are the two cam disks 9 and io arranged in special recesses of the base z i. - The bottom surface 12 and 13 (Fig. 3) of the two countersinks also form the end faces of the insulating material core i. The two cam disks 9 and io cannot be rotated with the switch axis 8 tied together. They raise the contacts 14, 15 of the contact levers or springs 2, 3, 4 and 5 depending on the switching task of the stationary contacts 6 and 7 of the insulating material core i from, the deflection at the ends of the protruding beyond the contacts 14, 15 Lever or springs takes place. The contact springs controlled by the lower cam disc step through the one arranged between the niches and the lower countersink Breakthroughs 18 (Fig. I and 3).
Die Kontaktringe 6 bzw. 7 bestehen zweckmäßig aus einem Metallband oder einem Metallring. Die Nockenscheiben 9 bzw. io sind entweder beide oder eine derselben mit axial gerichteten Sperrnocken 16 versehen, welche in entsprechende, an den Stirnseiten des Isolierstoffkernes vorgesehene Gegennocken eingreifen bzw. mit ihnen zusammenwirken. Sie sind in diesem Fall auf der Achse 8 in Längsrichtung verschiebbar und stehen unter dem Einfluß der axial wirkenden Feder 17.The contact rings 6 and 7 are expediently made of a metal strip or a metal ring. The cam disks 9 or io are either both or one the same provided with axially directed locking cams 16, which in corresponding, the counter cams provided on the end faces of the insulating material core engage or cooperate with them. In this case you are on axis 8 in the longitudinal direction displaceable and are under the influence of the axially acting spring 17.
