SU48571A1 - Device for automatic telephone station - Google Patents

Description

The proposed automatic telephone station is based on the use of a device in which, for the purpose of simultaneously servicing several conversational circuits with one searcher, fast-moving levers are used to install contact brushes; unrelated to testing the potentials of the contact field, and locking teeth, mounted with a relay on the brush path, and stopping brushes against the strings.

The searcher (Fig. 1) consists of 1) a contact field, which is a frame of 100, for example, bare bronze strings 13, arranged in one row;

2) groups of contact brushes 1 capable of moving horizontally along the contact field. The number of brushes in the finder can. reach up to 25 shtukuk;

3) a driving mechanism consisting of a) a first locking device having ten locking teeth of ten 16 and ten locking teeth of units 17, which can mount the driving mechanism in one hundred positions to connect the brushes with any pair of strings of the contact field. This installation is made by electromagnets of tens of 18 and electromagnets of units 19; b) a second locking device consisting of five locking group teeth 20 and five kind of locking teeth 2 /.

The five electromagnets of the group 22 and the five electromagnets of order 23 can set the second locking device to 25 positions to isolate any finder contact brush; c) the actual driving mechanism, consisting of moving parts 24 (grippers), which can be moved along the contact field by means of coupling gear 25 and solenoids 26.

As it moves, part 24 captures the selected brush and sets it against the required strings of the contact field.

The driving mechanism plays the role of a telephone operator for connecting the brushes to the contact field. After each compound, it is released and ready for new compounds.

The work of the proposed seeker is based on the complete separation and independence of the electrical circuits of the circuit from mechanical processes. Testing the potentials of the contact field, testing the potentials when searching for calls, determining the freeness of lines and brushes and the state of the line (called subscriber) is performed by purely electrical (relay) means without the aid of a driving mechanism. The selection of brushes and their installation in the contact field are made by the driving mechanism

mechanically — by locking the ground teeth of the brushes mounted on the path.

The work of the driving mechanism is as follows: 1) locking devices work properly; a) the first locking device pushes the locking tooth 17 against a pair of strings, b) the second locking device pushes the locking teeth 21 against the selected brush and selects it, 2) then a quick movement (start) of the moving parts of the mechanism 24, which in its the paths pick up the selected brush and stop when pushing (stop) with stop tooth 17 against the corresponding pair of strings.

After that, the brush remains connected to the contact field, and the driving mechanism returns to its original position and is ready for new connections.

In the station, it is used to control the searchers from the register side by sending pulses | different polarity and frequencies.

This is accomplished with a circuit having a connection to a contact field, brushes and a twisting mechanism.

All relays are assembled on a separate plate (relay plate, shown in phi, r. 2), which is connected to the finder by flexible cables and plug sockets.

Each plate. Has a set of linear relays / o, / 1, / 2--49 separation relays TO, rj, / 2....Gd9 (or supply relays). In addition, there is a first special circuit having a set of relays di, d.-diQ, and relay units 1-, 4 .... / IO, and a second special circuit having a set of group relays: ri, r ... and since then the relay relays p, pg, .... p, g ,.

In each case, the connection will occur as follows.

1. In the case of call retrieval:

a) the first circuit, which has a relay of relays and a relay of units, is connected with linear relays of subscribers and the first locking device in such a way that when the latter picks up the phone, one of the relays of ten and relays of units is activated, showing the string number

contact floor belonging to the subscriber.

; Simultaneously with the operation of the relay of the first circuit, one of the electromagnets of the descendors 18 and 19 of the units of the first locking device pushes the locking tooth / 7 against the strings of the subscriber picking up the receiver;

b) the second special scheme, having group and order relays, is connected with the linear relay and the second stopping device in such a way that, when the subscriber picks up the handset, one relay of the groups and order relays operate, showing the number of one of the free brushes in this .moment.

At the same time, one of the electromagnets, the group 22 and the order of 25 in the second locking device, is triggered, and the locking tooth is pushed out against the brush intended for connection;

c) after this, the driving mechanism is triggered, which with a quick movement captures with part 24 the selected brush and connects it with the subscriber's strings, see more: the tube. After that, the driving mechanism is ready to serve the new subscribers.

2. In the case of the management of the seeker by the register and finding a free line:

a) received from the subscriber by the register of a series of pulses are recorded and encrypted in single pulses of the combinational current. Each digit of the ten corresponds to a combination of two frequencies and polarities of the battery;

b) the first device circuit is connected to the contact field of the searcher and registers in such a way that when receiving the combination current from the register in the first special circuit, the tens relay corresponding to this combination current is triggered, which with its contacts selects a decade of strings and connects it to relay units.

Unit relays are interconnected in such a way that only one of them is activated, which corresponds to one of the free lines selected in a decade.

The triggered relays of the tens and the relays of the units show the number of contact strings in a multiple field, with which it is necessary., to connect the brushes, which received a pulse from the register.

At the same time, one of the electromagnets of tens of 18 and units / 9 is triggered, pushing out the locking tooth 77 against the selected strings;

c) the second circuit is so connected with the brushes that when a pulse arrives from the register, one group and one order relay is triggered, which determines the number of this brush.

At the same time, it is triggered by one of the electromagnets, a group 22 and an order of 23 in the second locking device, which pushes the brush through which the pulse from the register has been received.

After this, the driving mechanism is quickly activated and the selected brush is connected with the selected strings of the contact field.

3. In the case of a linear connection:

a) from the register through the brush come two pulses of combinational current.

From the first impulse, one of the tens relays (corresponding to the combination current) of the first circuit is activated

and highlights the decade of the jet, in which the callee is located.

In the second pulse, one of the relay units is triggered; 1a | en || ft these, I select the callee subscriber himself, which will be tested.

b) if the subscriber is free, the first and second locking devices are triggered in the manner described above and the driving mechanism connects the brush with the strings. ,

The subject matter of the invention.
