SU20151A1 - Call Regulator - Google Patents

Description

The proposed call handler shown in the schematic drawing is intended to be used on keyless telephone exchanges.

The regulator consists of an axis on which two fist washers A and B are insulated from it, Washer A is equipped with a pair of closure springs, and the washer B is two closure springs. With the help of the ZB and ZM gearing, this axis is associated with the axis carrying the ratchet X, driven by the C dog mounted on the Anchor I of the stepping finder. Anchor L has a pin designed to open contacts 1-2 of the step finder.

The RG relay, triggered immediately after the call is made and the telephone operator inserts the interrogation plug into the corresponding socket, is used to pre-connect the turntable to the subscriber’s line and then to stop the passage of direct current through the secondary winding of the transformer, as a result of which the further call goes through the fixed capacitor. The circuit of the rotator in this case is as follows: minus, contacts 6-7 of the relay PI, resistance 25, winding 26 of the electromagnet of the rotator.

contact 3, measles of a rotator, plus. The armature of the rotator will vibrate, closing contacts 1-2 of the primary windings 27 of the transformer. Due to the fact that current in different directions passes through the primary windings, an alternating current entering the subscriber's line is induced in the secondary winding 23 of the transformer shunt by capacitor 28. The call should last about three seconds, which is done with the call control and a special relay, not shown in the drawing. Since, when the telephone operator leaves the ring plug, the RT relay is in action, its contacts 6-7 are closed, and therefore, the circuit of the stepper finder of the RL closes (minus, contacts 7-6 of the RT, winding PJT, contacts 1-2 of the RL, plus), at what relay RTT works, attracts measles I, a dog C t is not behind a ratchet X for one tooth, and measles, reached the contact springs of a 12-step Iskattel RP, opens them with a pin K. The current in the RI winding is interrupted, measles w, retracted by the spring, will move back, and the dog will jump off again to the next ratchet lip. The current circuit is re-established, and measles will result in about eighteen

vibrations per second, the drive to rotate washers A and B. The washers have protrusions, which, when rotated, close contact springs 1, 2 and 3, 4. Contact springs and protrusions are arranged so that when the protrusion of the disk Jj opens contact 1-2, Fast) n disk L closes the contact 3-4,. while the closure of the contacts 3-4 occurs after the opening of the contacts 1-2. The disks rotate as long as the PT relay is energized.

Contacts 1-2 of the P-ZT step finder are shunted by a capacitor 30. At the contact 2 of the washer L, one of the ends of the winding of the CP- relay is connected, and at the contact of 3 of the washer A is one of the ends of the winding of the CP.

When the subscriber responds, due to the disconnection of the relay and the relay, the relay winding circuit P / opens, as a result of which the measles release contacts 6-7 and

the step finder circuit is interrupted, the washers A and B stop and they will not rotate further until the next call.

The subject of the patent.

The call regulator, characterized by the fact that a cam washer with a pair of contact springs operating on a closure and a cam washer with a pair of contact springs operating on a trip, are mounted on the same axis separately from it and are connected by a mesic gear wheel with the other gear wheel, which is on the same axis with the ratchet, driven in by the stepper finder dog interrupting the power supply circuit of the call control magnet at each attraction of the corr.
