Description

Bei elektrischen Schaltern oder elektrischen Schützen kommt es vor, daß mehrere Kontakte bzw. Paare von Kontakten gleichzeitig geschlossen oder geöffnet werden müssen. Das Öffnen und Schließen dieser Kontakte geschieht durch ein einziges Organ. Damit der Kontaktdruck bei allen Kontakten ausreichend groß ist, benutzt man Kontaktfedern, auf die das Betätigungsorgan einwirkt. Die Kontaktfedern biegen sich je nach dem erforderlichen Kontaktdruck entsprechend durch. Diese Einrichtung erfordert aber oft viel Raum, der das Gerät erheblich vergrößert. Erfindungsgemäß soll deshalb das die Kontakte betätigende Organ für jedes Kontaktpaar mit einem Bolzen versehen werden, der auf das Kontaktpaar drückt und dabei unter'der Einwirkung einer an dem gemeinsamen Organ abgestützten Feder steht, deren Druck größer ist als der erforderliche Kontaktdruck.With electrical switches or electrical contactors it happens that several contacts or pairs of contacts are closed or opened at the same time Need to become. The opening and closing of these contacts is done by a single one Organ. So that the contact pressure is sufficiently high for all contacts, used contact springs on which the actuator acts. Bend the contact springs depending on the contact pressure required. This facility but often requires a lot of space, which increases the size of the device considerably. According to the invention should therefore the organ that actuates the contacts for each pair of contacts with one Bolts are provided, which presses on the contact pair and thereby under'der action a spring supported on the common organ, the pressure of which is greater than the required contact pressure.

Die Abb. i zeigt beispielsweise ein elektromagnetisch gesteuertes Kipprelais, bei dem der Kontaktdruck durch die Durchbiegung der Kontaktfedern selbst erzeugt wird.Fig. I shows, for example, an electromagnetically controlled one Toggle relay in which the contact pressure is generated by the deflection of the contact springs themselves is produced.

In der Abb. 2 ist ein unter der Einwirkung einer Feder stehender Bolzen abgebildet, der das Kontaktpaar zusammendrückt.In Fig. 2 is a pin under the action of a spring shown pressing the pair of contacts together.

Das Kontaktpaar i, 2 wird durch Niederdrücken der Kontaktfeder 4 mit ihrem Kontakt i von dem elektromagnetisch gesteuerten Betätigungsorgan 3 geschlossen. Um eine wirkungsvolle Durchfederung der Kontaktfeder 4 zu erreichen, muß das Kontaktpaar i, 2 von der Druckrichtung des Organs 3 um einen gewissen Betrag auseinanderliegen. Dadurch wird das Gerät in seiner Breite erheblich größer. Erfindungsgemäß wird nun das Organ 3 (Abb. 2) für jedes Kontaktpaar mit einem Bolzen 5 versehen, der unter dem Druck einer Feder 6 steht. Diese Feder 6 stützt sich in dem Organ 3 ab. Der Druck der Feder 6 ist um einen gewissen Betrag größer als der an den Kontakten i, 2 zur Stromübertragung erforderliche Kontaktdruck. Bei Anwendung dieser Einrichtung kann das Kontaktpaar unmittelbar unter dem Betätigungsorgan 3 liegen. Dadurch wird das Gerät in seiner Baubreite erheblich schmaler.The contact pair i, 2 is by pressing down the contact spring 4 with their contact i closed by the electromagnetically controlled actuator 3. In order to achieve effective deflection of the contact spring 4, the contact pair must i, 2 are apart from the pressure direction of the organ 3 by a certain amount. This makes the device considerably larger in width. According to the invention is now the organ 3 (Fig. 2) provided for each pair of contacts with a bolt 5, which under the pressure of a spring 6 is available. This spring 6 is supported in the organ 3. Of the The pressure of the spring 6 is greater than that at the contacts i by a certain amount, 2 contact pressure required for power transmission. When using this facility the contact pair can be located directly below the actuating member 3. This will the width of the device is considerably narrower.
