Description

.1 The invention relates to devices for signaling or marking some state of groups of apparatus or lines.

It is already known the inclusion of a working circuit in the working and idle contacts. The present invention has in mind an electrical connecting device for signaling or for marking a state of a group of devices or lines by means of a number of relays belonging to various devices or lines. The relays are designed in such a way that they control the current circuit in the signal or marking arrangement in such a way that the signal or marking device is activated only when the number of relays in the relay is equal to or more than the minimum predetermined number of them, but stays idle until the number of simultaneously operating relays is less than the minimum number mentioned. Connecting devices of the kind mentioned can, for example, be used in automatic telephony in order to divide the load between several groups of voters or connecting lines, and one of these groups is marked as soon as the number of calls in this group reaches or exceeds some predetermined number.

The present invention consists in general terms in a signaling or marking circuit of a current depending on the contacts of said relays and is characterized in that said circuit passes sequentially through the / contacts of several relays in such a way that it is closed by the working contacts of the magnetized relays and the rest contacts relay.

In FIG. Figure 1 depicts one form of implementation of such a connecting device in which the signal or marking device starts operating when at least three relays are in operation at the same time; FIG. 2 illustrates such a connecting device in which a signaling or marking device is driven by at least three simultaneously operating relays, and FIG. 3 is the same connecting device for at least five simultaneously operating relays; FIG. 4 —application of the present invention for reciprocal: controlling two-devices or groups of lines.

The device shown in FIG. 1, consists of a switch of O /, ORi, etc. switching relays, which must be actuated from their respective apparatus or lines. The said relays control the current path to the group marker relay GR, which through its contact / can control the current path to the corresponding signaling or marking body for marking the said group of apparatuses or lines occupied. The named current circuit also contains a current source E and a resistance R. A current circuit branch attached to one of the 6aTapeji poles is connected to the spring 2 of the relay, while another branch connected to the other battery pole is connected to the other contact spring 3 of the same the relay and with it the contact springs 4, 5, 6 relays,,. Contact spring 2: normally touches the contact, the rest 7, which is connected to the contact spring 8 of the OR relay. When the relay ORi has its own measles, the spring 2 makes contact with the working contact 9, which is connected to the contact spring U of the relay OR Contact springs 8 and / O likewise normally touch the contacts 77, 72. When the OR relay does not have its own final contact, the spring 8 contacts the contact 72, and the spring W contacts contact 13, which is connected by conductor 14 to the same contacts 75, 16, 17 and 18 relays, OR, OR- ,, OR . The rest contacts 7 /, 12 are connected to the contact springs 19, 20 of the relay OR, and similarly its rest contacts 27, 22 are connected to the contact springs 23, 24 of the relay OR, etc., as shown in the diagram. The last PJELE OR has only one contact spring 25. Thus, two series are obtained in series between each other connected contacts, which, when the relay is magnetized in various combinations, act as follows.

If only one of the relays is triggered, then it is clear that such a state of the relay group can in no way affect the marking current circuit, which thus remains open. The same will happen if the measles of two any relays are simultaneously attracted. If, however, three any relays, for example, an O /, O /, relay, are simultaneously turned on, the current labeling circuit is closed through pins 2, 9, 10, 13, 15, 20, 8, 3. If instead suppose that the relay is simultaneously pulled in and, then the current circuit is closed by contacts 2, Р, 10, 72, 20, 15, 16, 24, 22, 19, 77, 8, 7, 3. If the relay is OR, ORr, , ORg would work simultaneously, then -... the current circuit would turn out, closed by contacts 2, 7, 8, 11, 19, 21, 25, 26, 27, 17, 18, 25, 28,29,30, 6, Thus, it is clear that the current circuit should always be closed through two series of series-connected working cells. bars and rest contacts. If the four measles relays, for example the OKz, OR, ORr ,, ORe relays, are simultaneously pulled, the same result will be obtained, since one branch of the circuit is connected to the conductor 74 by contacts 2, 17, 8, 77, 19, 22, 24, 16, while the other branch of the circuit will receive a connection to the conductor 14 through both contacts 77, 27, 26, 23, 21, 5, and through contacts 18, 25, 28, 29, 30, 6. That’s however, it will be obtained if measles of five or six relays are simultaneously engaged. It is clear from the above that one branch of the circuit always receives a connection to the conductor 7- /, as soon as the measles of at least two relays are turned on simultaneously. Therefore, the connecting device shown in FIG. 1, can be changed so that the marking relay is activated as soon as at least two relays of any kind work simultaneously. It is clear that for this purpose one branch of the chain b must be connected directly to the CONDUCTOR 14 and the contact springs 3, 4, 5, 6 disappear. The marking current circuit will then close through one series of working contacts and quiescent contacts.

Shown in FIG. 2, the form of a similar device encompasses eight switching relays, and the marking relay should work only when at least four relays work simultaneously. The device of the relay contacts is quite similar to the device of FIG. 1 with the only difference that the number of relay contacts, or ORr, is greater than their maximum number on any of the relays of FIG. 1, and here three series of series-connected contacts are obtained. The marking circuit is closed, as in FIG. 1, only through two series of series-connected contacts, namely, both through a series of contacts, with which a branch of the circuit is connected to the conductor 14, and through a series of contacts, the conmi conductor is connected to the branch b of the circuit. If the circuit branch b is connected directly to conductor 14, then such a relay group can be used to mark at least three simultaneously operating relays, in exactly the same way as described with reference to FIG. 1, with the contacts 3, 4, 5, 6, 31 disappear.

FIG. 3 shows the connecting device in which the marking relay 3 / should work as soon as the measles of at least five relays are simultaneously engaged. The number of relays will be equal to ten. The operation of such a connecting device is completely similar to the operation of the devices shown in FIG. 1 and 2, and therefore does not require a more detailed description.

The device according to FIG. 4 covers two series A, B of switching relays corresponding to two different groups of lines or devices. Each relay group controls a current circuit through a respective GR or HR marker relay, which should operate as soon as at least three relays in the respective group will work simultaneously. Each relay group contains six relays. Each relay group has a KR or LR relay,

of which the current circuit is controlled in such a way that it closes when none of the main relays is working, so does the MR or NR relays, the current circuits of which are controlled by the relay so that they close when only one of the main relays is activated. Thus, normally the KR relay receives current through the quiescent contacts of all the main relays. In this case, the GR relay is also magnetized for a short moment, but as soon as the KR relay doesn’t have its own measles, the GR relay will be closed for a short time by terminal 32. All of the above applies to the LR relay. If any of the main relays, such as relays. will work, then 1: barely MR will receive current through the working contact 33 of the relay and the rest contacts of all other main relays. Simultaneously, with this, contact 34 will interrupt the circuit of the KR-relay. As soon as the MR relay contacts its MR, contact 55 of the MR relay and contact 36 of the LR relay is closed for a short GR relay. The NR relay is designed in such a way that it works in exactly the same way as the MR relay. When it doesn’t have its own measles, contact .57 of the NR relay and contact 37 of the KR relay shuts down the HR relay for a short time.

The proposed device aims to keep one of the groups of lines or devices corresponding to the relay groups A, B available for connections, the advantage being given to the group that currently has fewer occupied lines or devices. If, therefore, none of the main relays in group A. is working, while in group B only one of the main relays is operating, then the KR and NR relays will be magnetized. The KR relay will close OR for a short time, in which group A is marked free. At the same time, the relay / C / „breaks the short circuit of the HR relay, which, therefore, does not have its own measles and marks Group B with an occupation. If, instead, it is assumed that only one main relay operates in jB group, while several main relays operate in group A, then the GR relay will work, and the HR relay will be closed for a short time by contacts 37 and 38. Thus, group A will be marked for occupation, and group B is available. When three. or

more basic relays operate simultaneously in both groups A and B, and both groups are labeled as busy by the magnetisation of the GR and HR relays.

Each of the two relay groups also has an ERr ,, ER and-FR ;, FRfi relay, which serve to close any signal or marking current circuit when, respectively, the ORr ,, relay ORe or, PRu will work together with at least three any ORi-OR, relays.

If, for example, it is assumed that the ORj, OR, ORa relays operate simultaneously with the ORn ,, relay, then both ends of the relay winding will be connected to the negative pole of the current source, namely, one end through contacts 38.39, 40 and the other end contacts 41 , 42, 33, 5, with the ER relay short-circuited. In view of this, the signal or marking current circuit through contacts 44 and 45 is closed. Similarly, the relay works if the ORe relay operates when at the same time at least three ORi-ORi relays also work. ,
