Description

Die Erfindung betrifft einen Mikroschalter mit elektrischen Kontakten nach dem Oberbegriff des Schutzanspruches 1.The invention relates to a microswitch with electrical contacts according to the Preamble of protection claim 1.

Ein derartiger Mikroschalter ist aus der DE-PS 40 02 371 C2 bekannt. Dabei wird ein mehrfach gebogener Schalthebel verwendet, wobei das Hauptaugenmerk auf der Abdichtung der Eintrittsöffnung des Hebels in das Innere des Mikroschalter-Gehäuses liegt.Such a microswitch is known from DE-PS 40 02 371 C2. Doing so a multi-bend shift lever is used, with the main focus on the sealing of the lever's opening into the interior of the microswitch housing lies.

Ein anderer Mikroschalter ist beispielsweise aus dem GbM 89 08 271.0 bekannt, bei dem zwei verschieden lange einseitig angelenkte Hebel miteinander zusammenwirken, um bei kleinstmöglicher Baugröße eine sehr geringe Betätigungskraft zu ermöglichen, wobei dennoch eine große Kontaktkraft gewährleistet sein soll, wie sie beim Schalten hoher Leistungen erforderlich ist.Another microswitch is known for example from GbM 89 08 271.0, where two levers of different lengths are hinged together, in order to have a very low actuation force with the smallest possible size to enable, while still ensuring a large contact force should, as is required when switching high powers.

Vergleichbare Mikroschalter werden mit Vorteil beim Überwachen von Elektromagneten verwendet, wie sie zum Betätigen von magnetgesteuerten Sicherheitsbremsen bei Aufzügen und von magnetgesteuerten mechanischen Wellenkupplungen und dgl. dienen.Comparable microswitches are advantageous when monitoring electromagnets used as for the actuation of magnetically controlled safety brakes for elevators and magnetically controlled mechanical shaft couplings and the like.

Bei Sicherheitsbremsen insbesondere für Anwendungen in der Aufzugstechnik (Hubantriebe) gibt es häufig Vorschriften, den Schaltzustand der Bremse zu überwachen (sogenannte Lüftüberwachung). Dazu ist es nötig zu wissen, ob die bewegliche Platte, die die Anpresskraft auf die Reibflächen überträgt, an diesen anliegt oder ob sie gelüftet ist. Üblicherweise wird der Hub, den die bewegliche Platte dabei ausführt, mit einem Mikroschalter abgefragt.With safety brakes, in particular for applications in elevator technology (Linear actuators) there are often regulations regarding the switching status of the brake monitor (so-called release monitoring). For this it is necessary to know whether the movable plate, which transfers the contact pressure to the friction surfaces is present or whether it is ventilated. Usually the stroke that the movable Plate executes, queried with a microswitch.

Bei vielen Bremsen besonders in der Aufzugstechnik ist es zudem erforderlich, dass die Bremsen beim Schalten keine lauten Geräusche erzeugen. Nach heutigem Stand der Technik ist es dazu neben weiteren Maßnahmen nötig, den Hub der beweglichen Platte auf ein möglichst geringes Maß zu beschränken. Hier tritt sehr leicht das Problem auf, dass der Hub womöglich nicht mehr ausreicht, den Schalter mit ausreichender Sicherheit zu betätigen.With many brakes, especially in elevator technology, it is also necessary that the brakes make no loud noises when shifting. According to today In addition to other measures, the state of the art requires the hub to limit the movable plate to the smallest possible extent. Here occurs very easily the problem that the stroke may no longer be sufficient Operate switches with sufficient safety.

Gewöhnlich wird dieses Problem gelöst, indem Schalter mit sehr kleiner Schalthysterese verwendet werden und bei der Montage der Schaltpunkt extrem genau eingestellt wird. Auch Hebelkonstruktionen finden heute schon Anwendung. So bestehen die bekannten Konstruktionen aus einem Hebel, der auf einem Bolzen gleitgelagert ist, was mit den ebenfalls bekannten Risiken von Relativbewegung, Klemmen, Fressen, Spiel, Verschmutzung etc. einhergeht. Außerdem führt dies zu höheren Herstellkosten durch die höhere Zahl der Einzelteile in Produktion und Montage.This problem is usually solved by switches with very small switching hysteresis can be used and the switching point is extremely precise during assembly is set. Lever designs are already used today. So the known constructions consist of a lever on a Bolt is slide-mounted, which is associated with the known risks of relative movement, Pinching, fretting, play, pollution etc. goes hand in hand. Moreover this leads to higher manufacturing costs due to the higher number of individual parts in production and assembly.

Der Erfindung liegt die Aufgabe zugrunde, einen solchen Mikroschalter zu schaffen, der eine billige Massenfertigung ermöglicht, trotzdem aber bei der Übersetzung kleiner Wege in große Wege eine lange Lebensdauer hat und zuverlässig arbeitet. The invention has for its object to such a microswitch create that enables cheap mass production, but still at Translation of small routes into long routes has a long service life and is reliable is working.

Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Schutzanspruchs 1 gelöst. Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen.This task is carried out with the characteristic features of the protection claim 1 solved. Further features of the invention emerge from the subclaims.

In der Folge wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung beschrieben. Es zeigen:

  • Abb. 2 das Übersetzungsverhältnis der benutzten Hebel:
  • Abb. 3 ein Zwischenerzeugnis für die Herstellung einer erfindungsgemäßen Hebelanordnung; und
  • Abb. 4 den Anbau eines erfindungsgemäßen Mikroschalters z. B. an eine Bremse.
    • An exemplary embodiment of the invention is described below with reference to the drawing. Show it:
  • Fig. 1 is an oblique view of a microswitch according to the invention:
  • Fig. 2 the gear ratio of the levers used:
  • Fig. 3 shows an intermediate product for the manufacture of a lever arrangement according to the invention; and
  • Fig. 4 the cultivation of a microswitch according to the invention z. B. on a brake.

    • Der Mikroschalter 1 nach Abb. 1 besitzt eine nicht näher dargestellte herkömmliche elektrische Kontaktanordnung, die in ein Gehäuse 9 vorzugsweise aus Kunststoff eingegossen und daher nicht sichtbar ist. Von den beweglichen Kontakten der elektrischen Kontaktanordnung erstreckt sich ein Stößel 2 zu deren Betätigung seitlich aus dem Gehäuse 9 heraus. Der Stößel 2 liegt an einem Schalthebel 3 an, der zur Versteifung mit einer Längssicke 3a versehen ist, die auch durch eine Rippe ersetzt werden kann. Der Schalthebel 3 setzt sich fort in ein Festgelenk 4, von dem sich rechtwinklig ein Zwischenhebel 5 mit einer Längssicke 5a erstreckt, der an seinem anderen Ende ein Festgelenk 6 aufweist, von dem im rechten Winkel eine Seitenwand 7 einer Grundplatte 8 absteht. Das Gehäuse 9 ist mittels Schrauben 11 an der Grundplatte 8 befestigt; der gesamte Mikroschalter ist seinerseits als geschlossene Baueinheit mittels weiterer Schrauben 10 an dem zu überwachenden Aggregat befestigt (vergl. Abb. 4).The microswitch 1 according to Fig. 1 has a conventional one, not shown electrical contact arrangement, which preferably consists of a housing 9 Poured plastic and is therefore not visible. From the mobile A plunger 2 extends to contacts of the electrical contact arrangement Actuation laterally out of the housing 9. The plunger 2 is against one Switch lever 3, which is provided with a longitudinal bead 3a for stiffening can also be replaced by a rib. The shift lever 3 continues in a fixed joint 4, of which an intermediate lever 5 is at right angles with a Extends longitudinal bead 5a, which has a fixed joint 6 at its other end, from which a side wall 7 of a base plate 8 protrudes at right angles. The Housing 9 is fastened to base plate 8 by means of screws 11; the whole The microswitch itself is a closed unit using additional screws 10 attached to the unit to be monitored (see Fig. 4).

    Das Festgelenk 6 soll möglichst federnd nachgiebig sein und kann dadurch geschaffen werden, daß das Material an dieser Stelle etwas geschwächt ist, z. B. durch eine Bohrung, eine Einschnürung oder eine Verminderung der Materialdicke. Andrerseits soll das andere Festgelenk 4 ein möglichst steifer Winkel sein, so dass sich eine Auslenkung des Zwischenhebels 5 um die Achse des Festgelenkes 6 weitgehend starr auf den Schalthebel 3 überträgt.The fixed joint 6 should be as resilient as possible and can thereby be created be that the material is somewhat weakened at this point, e.g. B. by drilling, constricting or reducing the material thickness. On the other hand, the other fixed joint 4 should be as rigid as possible, so that there is a deflection of the intermediate lever 5 about the axis of the fixed joint 6 transmits largely rigidly to the shift lever 3.

    Für die Rückstellung des Schalthebels 3 und des Zwischenhebels 5 nach einem Schaltvorgang bedarf es keiner zusätzlichen eigenen Federn, wenn die eigene innere Federsteifigkeit der Hebelanordnung 3 bis 7, insbesondere des Festgelenkes 6 entsprechend bemessen ist, z. B. durch eine geeignete Werkstoffauswahl. Als Werkstoffe kommen in Frage Metallblech, Kunststoffspritzguß oder ein sonstiger korrosionsbeständiger Werkstoff.For resetting the shift lever 3 and the intermediate lever 5 after one Shifting process does not require additional springs of your own if your own internal spring stiffness of the lever arrangement 3 to 7, in particular the fixed joint 6 is dimensioned accordingly, for. B. by a suitable choice of materials. Suitable materials are sheet metal, plastic injection molding or another corrosion-resistant material.

B. einer elktromagnetisch gelüfteten Bremse zeigt Abb. 4, wonach der zylindrische Magnetkörper 12 eine am Umfang vorgesehene, in Richtung einer Zylinder-Mantellinie verlaufende Längsnut 13 aufweist, in die der Mikroschalter 1 als Baueinheit eingesetzt ist. Am Rand der dem Mikroschalter 1 zugewandten Stirnfläche des Magnetankers 14 ist ein axial in Richtung einer Mantellinie vorstehender kurzer Schaltstift 15 vorgesehen, der am Schaltpunkt P des Hebels 5 gemäß Abb. 2 angreift, um die Axialverschiebung des Magnetankers 14 auf den Zwischenhebel 5 des Mikroschalters zu übertragen.The assembly of a microswitch 1 on a unit to be controlled, for. B. one Electromagnetically released brake shows Fig. 4, after which the cylindrical Magnetic body 12 is provided on the circumference, in the direction of a cylinder surface line has longitudinal groove 13 into which the microswitch 1 as Unit is used.
