Изобретение относитс к импульсной технике .The invention relates to a pulse technique.

Известен релейный триггер, содержащий управл ющий ключ, переключаюодий контакт в цепи разв зывающих резисторов и диодов, два реле, контакт дл самоблокировки и диоды 1.A known relay trigger contains a control key, switches the contact in the circuit of the isolating resistors and diodes, two relays, a contact for self-blocking and diodes 1.

Недостатком этого триггера вл етс необходимость повыщени напр жени питани .The disadvantage of this trigger is the need to increase the supply voltage.

Наиболее близким по технической сущности к за вленному вл етс релейный триггер , содержащий реле подготовки и реле пам ти, обмотки которых включены в коллекторные цепи транзисторов, эмиттеры которых , соединены между собой и с каждым диодом, а базы подключены через резисторы к общей шине 2.The closest in technical essence to the claimed is a relay trigger containing a preparation relay and a memory relay, the windings of which are included in collector circuits of transistors whose emitters are connected to each other and to each diode, and the bases are connected via resistors to a common bus 2.

Недостатком этого триггера вл етс его сложность.The disadvantage of this trigger is its complexity.

Цель изобретени - упрощение триггера.The purpose of the invention is to simplify the trigger.

Это достигаетс тем, что в релейный триггер, содержащий реле подготовки и реле пам ти, обмотки которых включены в коллекторные цепи транзисторов, эмиттеры которых соединены между собой и с катодом диода, а, базы подключены через резисторыThis is achieved by the fact that a relay trigger contains a preparation relay and a memory relay, the windings of which are included in collector circuits of transistors whose emitters are connected to each other and to the cathode of a diode, and the bases are connected through resistors

На чертеже дана принципиальна электрическа схема триггера.In the drawing, a schematic diagram of a trigger is given.

Claims

It contains memory relay 1, preparation 2 relay, diode 3, transistors 4, 5, resistors 6, 7. Contact transducer contact group 8 includes preparation 2 relay in the transistor base circuit, and contact 9 of memory relay 1 is connected to the transistor power circuit. The diagram also shows the contact group 10 of the control circuit. Trigger works as follows. In the initial state, the contact groups 8 and 10 are open and the trigger is de-energized. When contact 10 closes, current flows through diode 3, emitter-base circuit of transistor 5, resistor 7. Transistor 5 opens along a collector circuit, relay 1 operates and closes group 8, transistor 4 remains closed with zero voltage, as its emitter-base circuit turns out to be short-circuited. Before the contact closure of group 8, the base has a more positive potential relative to the emitter, after the contact closure of group 8 is zero potential. As a result, there is no current in the collector circuit of transistor 4. After the opening of the contact 10, the transistor 5 remains conductive due to the self-blocking of the contact of group 8, the diode 3 is closed and a positive potential is removed from the base of the transistor 4. Through the emitter-base transition of transistor 4, a current flows to resistor 6, transistor 4 opens, relay 2 operates and switches its contact to group 8. When contact 10 re-closes, emitter-base transition of transistor 5 becomes short-circuited through contact 9 and contact of group 8. Transistor 5 locked, relay. 1 is de-energized and its contact 9 is opened. Relay 2 remains energized due to the de-energization of the emitter current through the contact circuit 10 - diode 3 - emitter of transistor 4. 27 After the opening of contact 10, the trigger is completely de-energized, and relay 2 returns to its original state. Claims of the invention A relay trigger containing a preparation relay and a pa.mty relay, the windings of which are included in collector circuits of transistors, the emitters of which are interconnected with the cathode of the diode, and the bases are connected through resistors to a common bus, characterized in a preparation relay contact group is connected between the diode anode and the bases of said transistors, and a memory relay contact is connected between the power source and the junction point of the emitters of the transistors.
