Description

Die bisherigen Haustürdruck- oder Zugkontakte, Badezimmerkontakte usw. haben den Nachteil, daß sich zwischen den Kontaktstellen leicht Oxyd bildet und festsetzt, wodurch sie versagen. Bei den ersteren müssen außerdem die Türpfosten oder Mauern, sehr zu ihrem Schaden, mit großen Löchern versehen werden. Auch ist für fast jede Art Kontakt eine besondere Form der Federn erforderlich. The previous front door push or pull contacts, bathroom contacts, etc. have the disadvantage that oxide easily forms and sets between the contact points, whereby they fail. The former also have to have large holes in the door posts or walls, much to their detriment will. A special shape of the springs is also required for almost every type of contact.

Das Wesen- des vorliegenden Erfindungsgedankens besteht nun darin, an Stelle der Blattfedern oder Druckstellen ineinandergesteckte Schraubenfedern (Zugfedern) zu verwenden. Es entsteht dadurch beim Niederdrücken der äußeren Feder ein schleifender Kontakt, welcher für alle Fälle sowohl als Druck- wie als Zugkontakt gebraucht werden kann. Ein besonderer Vorteil besteht noch darin, daß er durch Überziehen der äußeren Feder mit Gummi, Isolierband o. dgl. oder durch Ausbildung dieser Feder als biegsames Rohr gegen alle atmosphärischen Einflüsse vollkommen geschützt werden kann.The essence of the present inventive idea is to replace the Use leaf springs or pressure points nested coil springs (tension springs). As a result, when the outer spring is pressed down, a sliding contact is created, which in all cases both as Push and pull contact can be used. There is still a particular advantage in that he by covering the outer spring with rubber, insulating tape o. The like. Or by designing this spring as a flexible tube against all atmospheric influences can be completely protected.

In der Zeichnung ist der neue Kontakt in vergrößertem Maßstab als Druckknopfkontakt dargestellt, und zwar zeigt:In the drawing, the new contact is on an enlarged scale as a push-button contact shown, namely shows:

Abb. ι einen Querschnitt durch den Kontakt undFig. Ι a cross section through the contact and

Abb. 2 dessen Aufsicht.Fig. 2 its top view.

ι und 2 sollen die beiden, den Kontakt bildenden Schraubenfedern bedeuten, welche in entsprechend ausgebildete Köpfe der aus Isolationsmaterial hergestellten Böckchen 3 eingesetzt sind und Anschluß an die beiden Leitungsenden haben. 4 bedeutet eine Gummihülle, welche die Federn nach außen abschließt. Mittels des Druckknopfes 5 können die beiden Federn gegeneinandergedrückt werden. Natürlich lassen sich diese beiden Federn noch in anderer Ausführungsform mit demselben Grundgedanken zu einem Kontakt vereinigen, ohne daß hierdurch der Erfindungsgedanke geändert wird.ι and 2 are intended to mean the two helical springs forming the contact, which in correspondingly designed heads of the lugs 3 made of insulation material are inserted and have a connection to the two ends of the line. 4 means a rubber cover, which closes the springs to the outside. The two springs can be pressed against each other by means of the push button 5 will. Of course, these two springs can also be used in other embodiments unite the same basic idea to a contact without thereby affecting the inventive idea will be changed.

Patent-An spruch:Patent claim: Elektrischer Kontakt, insbesondere für Schwachstrom, dadurch gekennzeichnet, daß derselbe aus zwei ineinandergesteckten, für gewöhnlich nicht miteinander in Berührung stehenden Schraubenfedern (1 und 2) besteht, die evtl. noch durch eine Gummihülle (4) o. dgl. gegen die atmosphärischen Einflüsse geschützt sind, um durch einfaches Gegeneinanderdrücken der an die die beiden Leitungsenden angeschlossenen Schraubenfedern einen reibenden Kontakt erzielen.Electrical contact, in particular for low current, characterized in that that it consists of two nested, usually not in contact with each other helical springs (1 and 2), which may still be protected by a rubber sleeve (4) or the like atmospheric influences are protected to by simply pressing against each other the coil springs connected to the two ends of the line have a friction force Make contact.
