Description

1. Federsatz aus Federn und Zwischenlagen aus beliebigem, elektrisch leitendem oder nichtleitendem Material aufgebaut, dadurch gekennzeichnet, daß beim Aufbau keilförmige Zwischenlagen verwende: werden.1. Set of springs made of springs and intermediate layers made of any electrically conductive material or non-conductive material, characterized in that wedge-shaped intermediate layers are used in the construction: will.

2. Federsatz nach Anspruch 1, dadurch gekennzeichnet, daß die keilförmigen Zwischenlagen durch treppenartiges Aufschichten gleichmäßig starker Zwischenlagen verschiedener Länge erzielt werden. 2. Spring set according to claim 1, characterized in that the wedge-shaped intermediate layers are achieved by step-like layering of uniformly thick intermediate layers of different lengths.

sätze. Damit man keinen schiefen Aufbau des Federnsatzes erhält und denselben ohne Schwierigkeit zusammenpressen kann, sind außer den bereits erwähnten α noch weitere keilförmige Zwischenlagen b vorgesehen, deren Wirkung ohne weiteres aus den Abbildungen ersichtlich ist.sentences. In order to avoid a crooked structure of the spring set and to be able to compress it without difficulty, in addition to the already mentioned α, further wedge-shaped intermediate layers b are provided, the effect of which is readily apparent from the figures.

Die Herstellung der keilförmigen Zwischenlagen kann auf beliebige Art, z. B. durch Ziehen, Walzen, Pressen. Gießen, Spritzen usw., erfolgen. Die Zwischenlagen lassen sich auch durch einseitiges, treppeuartiges Aufschichten von gleichmäßig dicken Zwischenlagen herstellen, eventuell unter Anwendung eines Bindemittels, z. B. Isoiierlackes usw. (Abb. 2 und 4). Die einfachste Form einer solchen keilförmigen Zwischenlage ist ir. go Abb. 3 gezeigt und besteht aus einer gleichmäßig dicken Zwischenlage und einer zweiten, kürzeren, die einseitig auf der ersten liegt.The production of the wedge-shaped intermediate layers can be done in any way, for. B. by drawing, rolling, pressing. Pouring, spraying, etc. The intermediate layers can also be produced by one-sided, stair-like layering of evenly thick intermediate layers, possibly using a binding agent, e.g. B. Isoiierlackes etc. (Fig. 2 and 4). The simplest form of such a wedge-shaped intermediate layer is ir. G o Fig. 3 and consists of a uniformly thick intermediate layer and a second, shorter, which lies on one side on the first.

Claims (1)

Die vorliegende Erfindung betrifft einen Federsatz, der aus aufgeschichteten Federn und Zwischenlagen besteht, wie er vor allem in der Fernmeldetechnik zur Kontaktgabe in zahlreichen Ausführungsformen, z. B. als Ruhe-. Wechsel- und Arbeitskontakt usw., verwendet wird. Bisher wurden die Federn durch Biegen über die Elastizitätsgrenze so justiert, daß der gewünschte KontaktdruckThe present invention relates to a spring set made up of stacked springs and intermediate layers, as it is mainly used in telecommunications technology for making contacts numerous embodiments, e.g. B. as resting. Changeover and working contact, etc., is used. Previously, the springs were made like this by bending beyond the elastic limit adjusted that the desired contact pressure ίο oder die für den bestimmten Zweck nötige Federspannung erzielt wurde. Die Nachteile dieser Methode sind, daß die Federn beim Justieren in unkontrollierbarer Weise beansprucht werden und daß die Justierarbeit die Fabrikation wesentlich verteuert. Diese Nachteile werden bei der vorliegenden Erfindung dadurch vermieden, daß beim Aufbau des Federsatzes keilförmige Zwischenlagen (Abb. ι bis 4) zwischen den zusammengehörigen Federn oder zwischen Feder und Gegenlage in geeigneter Weise verwendet werden. Die Federn brauchen dann zur Erzielung der Federspannung nicht gebogen zu Λν-erden, sondern erhalten diese von selbst beim Zusammenpressen des Federsatzes. Dieses kann in beliebiger Weise, z. B. wie üblich. durch Schrauben erfolgen. Die keilförmigen Zwischenlagen können aus leitendem oder nichtleitendem Material hergestellt werden.ίο or the spring tension required for the specific purpose has been achieved. The disadvantages of this method are that the springs are stressed in an uncontrollable manner during adjustment and that the adjustment work makes manufacture considerably more expensive. These disadvantages are avoided in the present invention in that wedge-shaped intermediate layers (Fig. Ι to 4) are used in a suitable manner between the springs that belong together or between the spring and the counter-surface in the construction of the spring set. The springs then do not need to be bent to Λν-earth to achieve the spring tension, but receive this automatically when the set of springs is compressed. This can be done in any way, e.g. B. as usual. done by screws. The wedge-shaped intermediate layers can be made of conductive or non-conductive material. Die Steigung des Keiles wird mit Rücksicht auf die Maße der Feder und die erwünschte Federspannung gewählt. Die Abb. 5 und 6 zeigen nach dieser Art aufgebaute Feder-Pa τ ε χ T-Ax Sprüche:The slope of the wedge is desired with consideration of the dimensions of the spring and the Spring tension selected. Figs. 5 and 6 show a spring-Pa constructed according to this type τ ε χ T-Ax Proverbs:
