Description
Es ist bekannt, die Kontakte von Drehschaltern in Funkenkammern anzuordnen, die durch den Schaltersockel mit dem Schaltstern gebildet werden.It is known to arrange the contacts of rotary switches in spark chambers that be formed by the switch base with the star switch.
Die Erfindung bezieht sich auf Drehschalter mit in verschiedenen Höhen parallel zur Sockelstirnfläche liegenden ebenen Kontaktbahnen und einem Schaltrad mit verschieden langen, axial federnden Kontaktstiften, dieThe invention relates to rotary switches with in different heights parallel to Base face lying flat contact tracks and a ratchet wheel with different long, axially resilient contact pins that
ίο vorzugsweise an einer federnd und axial geführten Kontaktscheibe befestigt sind. Gemäß der Erfindung erfolgt die Kontaktunterbrechung zwischen treppenförmig liegenden ringförmigen Stirnflächen des Schaltrades und Sockels in nach außen abgedeckten, , von dem Schaltrad und dem Sockel gebildeten Funkenkammern.ίο preferably on a resilient and axially guided Contact washer are attached. According to the invention, the contact is interrupted between the stair-shaped annular end faces of the ratchet wheel and base in outwardly covered,, of the ratchet wheel and the base formed spark chambers.
Die Erfindung ergibt durch die sorgfältige Ausbildung der Funkenkammern, die für die einzelnen. Kontaktbahnen getrennt sind, eine sehr gedrängte und dabei leistungsfähige Anordnung. The invention results from the careful design of the spark chambers for the individual. Contact tracks are separated, a very compact and powerful arrangement.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.In the drawing is an exemplary embodiment of the invention shown.
Die Abb. ι und 2 zeigen Längsschnitte durch den Schalter nach den Linien A-B bzw. C-D der Abb. 3.Figs. 1 and 2 show longitudinal sections through the switch along the lines AB and CD of Fig. 3.
Abb. 3 zeigt eine Aufsicht,Fig. 3 shows a top view,
Abb. 4 einen Schnitt nach Linie E-F der Abb. 3.Fig. 4 is a section along line EF in Fig. 3.
Abb. 5 zeigt eine Schaltwalze mit aufgelegter Isolierstoffscheibe.Fig. 5 shows a shift drum with a layer of insulating material.
Der in den Abb. 1 bis 4 dargestellte Schalter ist ein zweipoliger Schalter. In einem Sockel a ist in an sich bekannter Weise eine Schaltachse b gelagert, die in ihrem oberen Teil in einem Bügele geführt wird. Ein Schaltradd ist ebenfalls in an sich bekannter Weise durch eine Schaltfedere mit der Schaltachse & verbunden. In dem unteren Teile des Schaltrades d befinden sich Aussparungen, in welchen Kontaktscheiben / angeordnet sind. Diese Kontaktscheiben/ sind Teile von Ringscheiben, die auf ihrer Innenseite teilweise umgebördelt sind und mit diesen Ansätzeng· in Aussparungen h des Schaltrades geführt werden. Die Federung der Kontaktscheiben wird durch mehrere Schraubenfedern/ erreicht, die ebenfalls in Aussparungen des Schaltrades angeordnet sind. An den Kontaktscheiben sind außen lange und innen .kurze Kontaktstifte befestigt, die auf entsprechenden, im Sockel α treppenförmig Hegenden Kontaktbahnen schleifen.The switch shown in Figs. 1 to 4 is a two-pole switch. In a base a , a switching axis b is mounted in a manner known per se, which is guided in its upper part in a bracket. A switching wheel d is also connected to the switching axis & in a manner known per se by a switching spring. In the lower part of the ratchet wheel d there are recesses in which contact disks / are arranged. These contact disks / are parts of ring disks which are partially flanged on their inside and which are guided with these attachments into recesses h of the ratchet wheel. The suspension of the contact disks is achieved by several helical springs /, which are also arranged in recesses in the ratchet wheel. On the outside of the contact disks long and short inside .short contact pins are attached, which grind on corresponding contact tracks in the base α in a step-shaped manner.
Wie aus Abb. 1 und 2 ersichtlich ist, schleifen die beiden langen Kontaktstifte k, k auf der äußeren Kontaktbahn m und die kurzen Kontaktstifte ti, η nach Abb. 4 auf der höher gelegenen inneren Kontaktbahn 0. As can be seen from Fig. 1 and 2, the two long contact pins k, k drag on the outer contact track m and the short contact pins ti, η according to Fig. 4 on the higher inner contact track 0.
Die Trennung der Kontakte, also die Strom-Unterbrechung, erfolgt in geschlossenen Funkenkammern, die einerseits von dem Ansatz ρ des Schaltrades d, anderseits von dem erhöhten Rand q. des Sockels α gebildet werden.The separation of the contacts, i.e. the current interruption, takes place in closed spark chambers, which are on the one hand from the approach ρ of the ratchet wheel d and on the other hand from the raised edge q. of the base α are formed.
Um das Entstehen von Stehfeuer an dem Kontaktring zu verhüten, ist dieser auf der Unterseite, wie aus Abb. S ersichtlich, mit einer Isolierringscheibe r versehen.In order to prevent standing fire on the contact ring, it is provided with an insulating ring washer r on the underside, as can be seen in Fig. S.
Durch die vorgeschriebene Anordnung wird auf einfache Weise eine sicher wirkende Schaltvorrichtung geschaffen, und zwar sowohl für einpolige als auch für mehrpolige Schalter.Due to the prescribed arrangement, a safe-acting one can be achieved in a simple manner Switching device created, both for single-pole and multi-pole Counter.
