Description

Es ist insbesondere bei Relais und Wählerkontaktfedern bekannt, die Kontaktfedern in einen durch Spritzen oder Pressen hergestellten Isolierblock einzubetten. Bei der Herstellung solcher Kontaktblöcke ergeben sich Schwierigkeiten, die dadurch entstehen, daß die Federn durch Deformierung oder Verformung ihre Charakteristik ändern.It is particularly known for relays and selector contact springs that Embed contact springs in an insulating block made by injection molding or pressing. In the production of such contact blocks there are difficulties that result arise that the springs by deformation or deformation of their characteristics change.

Die Erfindung vermeidet eineDeformierung oder Verformung der Kontaktfedern bei der Herstellung solcher Isolierblöcke dadurch, daß .die Halterung der Federn innerhalb des Isolierblockes nur an einigen Abstützpunkten erfolgt.The invention avoids deformation or deformation of the contact springs in the manufacture of such insulating blocks in that .the mounting of the springs takes place within the insulating block only at a few support points.

Die Erfindung wird im folgenden an Hand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigt Fig. i in perspektivischer Ansicht einen Isolierblock mit eingebetteten Kontaktfedern, Fig. ,z einen Schnitt gemäß der Schnittlinie A-A in Fig. i, Fig. 3 einen der Fig. z entsprechenden Schnitt einer anderen Ausführungsform der Erfindung. In Fig. i sind die Kontaktfeder a in einen Isolierblock e eingebettet. Wie aus Fig. --, deutlich sichtbar ist, stehen die Kontaktfedern nur --an ihren Rändern b oben und unten mit dem Isoliermaterial in Verbindung und werden dadurch gehalten. Darüber hinaus greift das Isoliermaterial mittels der schmalen Stege c die Federn oben und unten an zu dem Zweck, die Durchbrüche, die bei der - Einbettung entstehen, stawb,dicht abzuschließen, um so die Kontakte bei aufgesetzter Kappe vor Staub zu schützen.The invention is explained in more detail below with reference to the exemplary embodiment shown in the drawing. FIG. 1 shows a perspective view of an insulating block with embedded contact springs, FIG. 1, a section along the line AA in FIG. In Fig. I, the contact spring a are embedded in an insulating block e. As shown in Fig -., Is clearly visible, the contact springs are only --an their edges b up and down with the insulating material in connection and are held thereby. In addition, the insulating material engages the springs above and below by means of the narrow webs c for the purpose of sealing the openings that arise during the - embedding, in order to protect the contacts from dust when the cap is on.

In dem anderen Ausführungsbeispiel gemäß Fig. 3, die dem Schnitt gemäß Fig. z entspricht, ist von einer solchen staubdichten A@bschließung Abstand genommen. Bei dieser Ausführungsform greift das Isoliermaterial die Federn nur an den Rändern oben und unten an. Eine solche Ausbildung kommt zweckmäßig dann zur Anwendung, wenn die Kontaktblöcke durch eine gemeinsame Verkleidung aller Organe ohnehin gegen Staubeinwirkung geschützt sind. Um die Kontaktfedern in ihrer fixierten Lage zu sichern, sind die Federn bei beiden Ausführungsformen mit Einkerbungen d versehen, die eine Längsverschiebung der- Federn Verhindern.In the other embodiment according to FIG. 3, the section according to Fig. Z corresponds to such a dust-tight closure is dispensed with. In this embodiment, the insulating material only grips the springs at the edges up and down. Such a training is expediently used when the contact blocks by a common covering of all organs anyway against the effects of dust are protected. To secure the contact springs in their fixed position, the Feathers in both embodiments are provided with notches d, which allow a longitudinal displacement the feathers prevent.
