Description

Stromstoßsender für Fernsprechwählanlagen Die Erfindung bezieht sich auf einen Stromstoßsender für Fernsprechwählanlagen, der zwei durch Fremdstromimpulse gesteuerte Relais enthält. Diese Relais weisen unterschiedliche Ansprech- und Abfallverzögerungen auf und betätigen auf Grund dieser Unterschiede verschieden arbeitende Nummernschalterkontakte. Bei den Relais handelt es sich um die Wahlimpulsrelais, vorzugsweise das NSI-Relais.Impulse Transmitters for Telephone Switchboards The invention relates to on a surge transmitter for telephone systems, the two by external current impulses Contains controlled relays. These relays have different response and dropout delays and operate number switch contacts that work differently due to these differences. The relays are the dial pulse relays, preferably the NSI relay.

Gemäß der Erfindung soll die vorgeschriebene Impulsfolgefrequenz von 10 Hz wie auch ein Kontakt-Pause-Verhältnis von 1:1,6 eingehalten werden.According to the invention, the prescribed pulse repetition frequency should be 10 Hz as well as a contact-pause ratio of 1: 1.6 are maintained.

Hierzu sieht die Erfindung einen Schwingkreis vor, durch dessen Resonanzfrequenz sowohl die Sollfrequenz als auch das Kontakt-Pause-Verhältnis bestimmt werden.For this purpose, the invention provides an oscillating circuit through its resonance frequency both the target frequency and the contact-pause ratio can be determined.

Der Schwingkreis enthält, wie an sich bekannt, Induktivitäten und Kapazitäten. Seine Resonanzfrequenz wird jedoch zusätzlich durch Rückstellfederkräfte und Massenkräfte von mechanischen Elementen bestimmt, die mit ihm zusammenwirken.As is known per se, the resonant circuit contains inductances and Capacities. Its resonance frequency is, however, additionally due to restoring spring forces and inertia forces are determined by mechanical elements that interact with it.

Der Kern der Erfindung liegt somit darin, daß sowohl die Sollfrequenz als auch das Kontakt-Pause-Verhältnis durch die Bemessung der die Resonanzfrequenz bestimmenden Mittel gegeben ist.The essence of the invention is therefore that both the target frequency as well as the contact-pause ratio by measuring the resonance frequency determining means is given.
