Description

Bei elektrischen Steckvorrichtungen, die zum Anschließen elektrischer Geräte an ein Leitungsnetz benutzt werden, besitzen die Kontaktfedern sehr oft einen für den Stromdurchgang zu geringen Querschnitt, so daß bei längerem Gebrauch der Steckvorrichtung eine starke Erwärmung auftritt. Außerdem haben viele Kontaktfedern noch den Nachteil, daß die Kraft zum Einführendes Steckers verschieden ist von der Kraft zum Herausziehen des Steckers. Bei Steckvorrichtungen geringer Polzahl hat dieses an und für sich nicht viel zu sagen. Es wirkt sich aber bei einer vielpoligen Steckvorrichtung oft sehr nachteilig aus.In the case of electrical plug-in devices that are used to connect electrical Devices are used on a line network, the contact springs very often have one too small a cross-section for the passage of current, so that with prolonged use the Connector a strong heating occurs. In addition, many have contact springs nor the disadvantage that the force for inserting the plug is different from that Force to pull out the plug. Has a low number of poles for plug-and-socket devices not much to say in and of itself. But it affects a multi-pole Plug-in device is often very disadvantageous.

Um idiese Ibeilden Mähgel an Steckvorrichtungen zu beseitigen, wird eine Kontaktfeder 2n Vorschlag gebracht, bei -der ?durch geeignete Formgefbung im Augenblick ides Stromdurchganges idurch (die Feder diese im Querschnitt verdoppelt wird und der Kontaktdruck der Feder sowohl beim Einsstecken als auch beim Herauswiehen des Steckers ungefähr die gleiche Bremswirkung hervorruft.In order to get rid of this problem on plug-in devices a contact spring 2n proposal brought in -the? by suitable shape in the Moment of passage of current through (the spring doubles this in cross-section and the contact pressure of the spring both when inserting and when pulling out of the plug produces approximately the same braking effect.

Die Feder wind erfindungsgemäß in Form einer 2 gebogen, !bei der das kreisförmige Teil' durch den Kontaktdruck des Steckers sich als vollständiger Ring ineinanderlegt. Dadurch kann ein Teil des Stromes durch die eine Ringhälfte und das andere Teil 1durch,die andere Ringhälfte der Feder laufen. Durch diese Unterteilung (des Stromes ist die Belastung der Feder geringer und mithin auch ihre Erwärmung.According to the invention, the spring is bent in the form of a 2 , in which the circular part is nested as a complete ring due to the contact pressure of the plug. As a result, part of the current can run through one ring half and the other part 1 through the other ring half of the spring. This subdivision (of the current means that the load on the spring is lower and, consequently, so is its heating.

Die Abb. @f zeigt zwei Klemmen mit der erfindungsgemäßen Kontaktfeder, bevor der Stecker in die Steckvorrichtung vollständig eingeführt ist. Die Abb. 2 zeigt dieselbe Einrichtung mit vollständig eingeführtem Stecker. Die Kontaktfeder r, deren Ende z zum Anschlufi des Anschlußdrahtes in der Klemme @dient, besitzt das ringförmige Teil 3, dessen freies Ende q: mit .dem übrigen Teil rder Blattfeder keine Berührung besifizt"solarnge der Stecker nicht eingeführt ist. Sobald der Stecker aber eingeführt worden ist, legt sich das freie Ende unter dem Druck des Steckers fest an der Feder an, so #daß der die Steckvorrichtung durchfließende Stroms durch die beiden Hälften des nunmehr geschlossenen Ringes fließen kann (wie A'bb. 2 zeigt). Mit dieser Anordnung ist es möglvch, durch eine verhältnismäßig kleine Kontaktfeder einen großen Strom fließen zu lassen, ohne daß die Feder dadurch eine Übermäßige Erwärmung erflährt.The Fig. @F shows two terminals with the contact spring according to the invention, before the plug is fully inserted into the connector. Fig. 2 shows the same device with the plug fully inserted. The contact spring r, the end of which z is used to connect the connecting wire in the terminal @ the ring-shaped part 3, the free end of which q: with the remaining part of the leaf spring no touch besimes "solarge the plug is not inserted. Once the plug but has been inserted, the free end lies under the pressure of the connector firmly on the spring, so that the current flowing through the plug-in device flows through the two halves of the now closed ring can flow (as Fig. 2 shows). With this arrangement it is possible to use a relatively small contact spring to let a large current flow without causing the spring an excessive one Experience warming.

Das ringförmige Teil kann auch aus mehreren Windungen bestehen, so -daß idadurch eine weitere Verstärkung das Federquerschnittes. eintritt, sobald die einzelnen Windungen sich glegernseitig berühren.The ring-shaped part can also consist of several turns, see above -that i thereby a further reinforcement of the spring cross-section. occurs as soon as the individual turns touch each other on the gimlet side.
