Description

Gebrauchsmusteranmeldung. Kontaktfeder far Meeserkontakte mit zusätzlichen : ringfarmigen Anpress- f-ede=, Die Neuerung bezieht sich auf eine Kontaktfeder für Messerkontakte mit zusätzlichen @ingförmigen Anpressfedern aus Stahl o. dgl, Derartige bereits bekannte Federn dienen zur Erhöhung des Kontaktdruskes und werden aus-rundem Stahldraht oder auch aus Stahlband hergestellte Solche Federn weisen in'Verhältnis zu ihres Materialaufwand eine geringe Federvirkung auf die insbe- sondere bei grösseren Kontakten völlig unzureichend ist. Gemäss der Neuerungvjlxd die den KontaLtdxuck erhöhende Yeder so aus- gebildete dass bei geringstes Naterialaufwand ein wesentlich grösserer Kontaktdruck erreicht v ; ird als bei den bisher bekann- ten Einrichtungen dieser Art. Zu. diesem Zweck wird eine ring- förmige Feder aus Flachsaterial verwendet, deren Querschnitt sich nach beiden Enden zu verjüngt.Utility model registration. Contact spring for sea contacts with additional : ring-shaped contact pressure f-ede =, The innovation relates to a contact spring for blade contacts with additional @ ing-shaped pressure springs made of steel or the like, such already known springs are used to increase the Kontaktdruskes and are made from round steel wire or from Such springs made from steel band assign in'Verstoff their material costs have a low spring effect on the particular is completely inadequate, especially for larger contacts. According to the innovation vjlxd the yeder increasing the contact pressure so formed that with the least amount of material an essential greater contact pressure reached v; than with the previously known ten institutions of this type. To. for this purpose a ring shaped spring made of flat material, the cross-section of which is used tapers towards both ends.

Die Zeichnung zeigt ein Ausführungsbeispiel gemäss der Neuerung Bild 1 zeigt die eingebaute Zusatzfeder in einen Lyrakontakt und Bild 2 eine Feder in zwei verschiedenen Ansichten.The drawing shows an exemplary embodiment in accordance with the innovation image 1 shows the built-in additional spring in a lyre contact and picture 2 shows a spring in two different views.

Die Kontaktfeder 1 ist auf dem ockel 2 befestgit. Die abgebogeen Teile er Kontaktfeder weisen Öffnungen 3 auf, durch die die Zusatzfeder 4 gesteckt wird. Die Zusstzfeder 4 drückt mit ihren beiden Enden 5 gegen die mit Ausnehmungen 6 versehenen Schenkel der Xentartfeder 1. Diese Ausnehmungen dienen gleichzeitig zur Balterung der Zusatzfedern 4. Die Zusatzfeder 4, die in Bild 2 deutlicher gezeigt vird, besteht aus Flachmaterial und weist an der Schnittlinie A-B den grössten Querschnitt auf. Von dieser Stelle au. s verjüngt sich der Querschnitt nach den beiden Enden 5 zu. Die Querschnittsverjüngung kann sowohl bei gleicher Materialstärke a (Bild 2) als auch bei nach beiden Enden 5 zu abnehmender Materialstärkserfolgen. 3 Schtitzanspxüche 2 Bilder The contact spring 1 is fastened on the ockel 2. The bent parts of the contact spring have openings 3 through which the additional spring 4 is inserted. The auxiliary spring 4 presses with its two ends 5 against the legs provided with recesses 6 the Xentart spring 1. These recesses also serve to Retaining the additional springs 4. The additional spring 4, which is shown in Figure 2 shown more clearly, consists of flat material and has the largest cross-section at the cutting line AB. From this point au. The cross section tapers towards the two ends 5. The tapering of the cross-section can take place both with the same material thickness a (Fig. 2) and with the material thickness decreasing towards both ends 5. 3 Schtitz requirements 2 pictures
