Description
При включении известных телефонных аппаратов системы АТС в линию наблюдаетс одиночный удар звонка. Такое же вление на-, блюдаетс при коротком замыкании линии и ее переполюсовке.When the well-known telephone systems of the PBX system are turned on, a single ring tone is observed in the line. The same phenomenon occurs when there is a short circuit of the line and its polarity reversal.
Описываемое устройство дл гашени одиночных ударов звонка телефонных аппаратов устран ет указанный недостаток, что позвол ет улучшить эксплуатацио-нные качества телефонных аппаратов. Дл этого в устройстве параллельно звонку подключены четыре вентил по схеме моста, в диагональ которого включены параллельно -соединенные конденсатор и сопротивление.The described device for quenching single ringing of telephone sets eliminates this drawback, which makes it possible to improve the operational qualities of telephone sets. To do this, in the device, in parallel with the bell, four valves are connected according to the bridge scheme, in the diagonal of which are connected the parallel-connected capacitor and resistance.
Принципиальна схема устройства приведена на чертеже.A schematic diagram of the device is shown in the drawing.
Параллельно звонку 1 телефонного аппарата, включенного в зажимы линии 2 через разделительный конденсатор 5, подключен контур . Этот контур содержит конденсатор 4 и сопротивление 5, включенные в диагональ выпр мительного мостика, который содержит вентили 6, 7, 8 и 9При включении аппарата в линию, ее переполюсовке или коротком замыкании на зажимах 2 возникает импульс напр жени , который прикладываетс к выводам звонка /. Однако сопротивление контура в момент действи импульса намного меньше сопротивлени катушки звонка.Parallel to the call 1 of the telephone set, which is included in the clamps of the line 2 through the separation capacitor 5, a circuit is connected. This circuit contains a capacitor 4 and a resistance 5, included in the diagonal of the rectifying bridge, which contains the valves 6, 7, 8 and 9 When the device is turned on, reversed, or short-circuited, a voltage pulse is applied to the terminals 2 . However, the resistance of the circuit at the time of the pulse is much less than the resistance of the bell coil.
Таким образом, при одиночных импульсах .контур шунтирует звонок . При поступлении повтор ющихс импульсов напр жени (сигнал звонка) конденсатор 4 зар жаетс - Шунтируюш,ее действие контура прекращаетс . Звонок 1 начинает работать.Thus, with single pulses. The contour shunts the bell. When repetitive voltage pulses arrive (bell signal), capacitor 4 is charged — shuntyuyush, its circuit action ceases. Call 1 starts to work.
Описанное устройство может найти применение в блокираторах дл спаренного включени .телефонных аппаратов. Этот контур надежно работает и не вносит больших потерь№ 146782 П р е л м е т и з (j б р е т с н и The described device can be used in blockers for paired activation of telephone devices. This circuit works reliably and does not introduce large losses. No. 146782 PRI e e m i s (j b e
Устройство дл гашени одиночных ударов звонка телефонных аппаратов, отличающеес тем, что параллельно звонку подключены четыре вентил по схеме моста, в диагональ которого включены параллельно соединенные конденсатор и сопротивление.A device for extinguishing single beats of the bell of telephone sets, characterized in that in parallel to the bell four gates are connected according to the bridge circuit, the diagonal of which includes a parallel-connected capacitor and resistance.
