Description
Kontakt feder Die Erfindung bezieht sich auf einen Sprungkontakt mit einer Spreizfeder, die beim Betätigen einen Totpunkt überschreitet und dadurch sprungartig von einer stabilen Lage in die andere wechselt. Contact spring The invention relates to a snap contact with a spreading spring that exceeds a dead center when actuated and thereby suddenly changes from one stable position to the other.
Sprungkontakte bestehen bekanntlich aus Federrahmen, Spreizfeder und Spreizlager, wobei die Spreizfeder bogenförmig zwischen Spreizlager und Federrahmen eingespannt ist und dadurch die gewünschte Eigenschaft erzielt wird, daß die Feder sprungartig zwischen zwei mechanisch stabile Lagen bewegt werden kann. Sprungkontakte werden in elektrischen Schaltern und in Reglern eingesetzt. Solche bekannten Sprungkontakte bestehen meist aus drei Teilen, mindestens aber aus zwei Teilen.As is known, snap contacts consist of spring frames, expanding springs and Expanding bearing, with the expanding spring arched between the expanding bearing and the spring frame is clamped and thereby the desired property is achieved that the spring can be moved suddenly between two mechanically stable layers. Jump contacts are used in electrical switches and controllers. Such known jump contacts usually consist of three parts, but at least two parts.
Der Erfindung liegt nun die Aufgabe zugrunde, einen Sprungkontakt mit einer einteiligen Kontaktfeder herzustellen.The invention is now based on the object of a snap contact to produce with a one-piece contact spring.
Erfindungsgemäß wird deshalb eine Sprungfeder vorgeschlagen, bei der Federrahmen, Spreizfeder und Spreizlager aus einem einzigen Teil bestehen, indem der Federrahmen durch Biegungen verkürzt wird. Dabei kann der Federrahmen beispielsweise S-förmig oder wellenförmig oder auf ähnliche Weise gebogen werden. Solche Kontaktfedern sind besonders vorteilhaft, da nicht wie bei den bekannten Konatruktionen die Einzelteile durch aufwendige Fertigungsarbeiten in zahlreichen Arbeitsgängen angepaßt und miteinander verbunden werden müssen.According to the invention, a spring is therefore proposed in which The spring frame, expanding spring and expanding bearing consist of a single part by the spring frame is shortened by bends. The spring frame can, for example S-shaped or undulating or bent in a similar manner. Such contact springs are particularly advantageous because the individual parts are not, as is the case with the known constructions through complex manufacturing work in numerous operations and adapted to each other need to be connected.
Die folgende Darstellung zeigt zwei Ausführungsmöglichkeiten für die erfindungsgemäße Kontaktfeder eines Sprungkontaktes.The following illustration shows two possible designs for the Contact spring according to the invention of a snap contact.
Fig. 1 und Fig. 2 zeigen eine Kontaktfeder, die aus einem einzigen Teil besteht, in Sicht von oben und in Seitenansicht.Fig. 1 and Fig. 2 show a contact spring, which consists of a single Part consists, in view from above and in side view.
Durch S-förmiges Verbiegen des Federrahmens 1 wird die bogenförmige Verspannung der Spreizfeder 2B die in das Spreizlager 3 eingreift, erreicht. Zur mechanischen Fertigung dieser Anordnung können die Stellen 4 und 5 der S-förmigen Verbiegung, an der der Federrahmen 1 mehrschichtig übereinanderliegt, beispielsweise verschweißt werden.By bending the spring frame 1 in an S-shape, it becomes arcuate Bracing of the expansion spring 2B which engages in the expansion bearing 3 is achieved. To the mechanical fabrication of this arrangement can place 4 and 5 of the S-shaped Bending at which the spring frame 1 lies on top of one another in several layers, for example be welded.
Fig. 3 und 4 zeigen eine andere Ausführungsform der erfindungsgemäßen Kontaktfeder. Die beiden Schenkel 6 und 7 des Federrahmens sind wellenförmig verbogen und versickt, so daß ebenfalls eine mechanisch stabile Verkürzung des Federrahmens erzielt wird.3 and 4 show another embodiment of the invention Contact spring. The two legs 6 and 7 of the spring frame are bent in a wave shape and sunk, so that a mechanically stable shortening of the spring frame is achieved.
