En stor svarighet vid konstruktioner av elektroniska telefonsystem ligger dari, att man ej har nagot elektroniskt kontaktelement, som är lampligt for systemets talkretsar. Man an darfor hanvisad till att anvanda elektromekaniska anordningar med metalliska korrtakter, men hittills inom automattelefonin anvanda kopplingsorgan are ej i alla avseenden lampliga harfor. A major responsibility in the construction of electronic telephone systems lies in the fact that there is no electronic contact element which is suitable for the system's speech circuits. Therefore, reference has been made to the use of electromechanical devices with metallic corridors, but to date coupling means used in automatic telephony are not suitable in all respects.

Speciella relakonstruktioner, soon aro lampade for elektroniskt styrda valjare, ha foreslagits. Exempel harpa arc de s. k. ferreedrelaerna av olika utforande, som I allmanhet innefatta tungrelakontakter med en yttre magnetkrets innehallande ett eller flera reman.entmagnetiska element, och vilka relaer kunna sammanstallas till valjare av godtyeklig storlek. Dessa konstruktioner aro emellertid i allmanhet relativt klumpiga och dyrbara. Special relay designs, soon to be illuminated for electronically controlled selectors, have been proposed. Examples are the so-called ferre relays of different designs, which generally comprise heavy relay contacts with an external magnetic circuit containing one or more remanent magnetic elements, and which relays can be assembled into selectors of any size. However, these constructions are generally relatively bulky and expensive.

Uppfinningen avser att eliminera dessa olagenheter och astadkomma en relamatris, som utgor ett enkelt och kompakt kopplingsorgan lampat for elektronisk styrning. Uppfinningen kannetecknas speciellt av ett relaerna polariserande magnetsystem, som innefattar ett antal parallella permanentmagneter forsedda med i tvâ parallella plan genom sagda permanentmagneters andar anordnade, parallella, som skenor utforda polskor av magnetiskt material, varvid ,permanentmagneterna arc sa vanda, att i vardera planet varannan skena har sydpols-, varannan nordpo1smagnetisering, av att vart och ett av ,sagda relaer innefatter en parallellt rued permanentmagneter- DupL kl. 21 a3: 22/ na, mellan sagda plan anordnad lindningsforsedd karna av ett material med tvd stabila till-stand av remanent magnetism, -varvid vardera anden av sagda karna an belagen i en Oppning mellan tvá skenor i respektive plan, och av att som rarliga organ vid sagda karnas andar aro anordnade kulor av magnetiskt material. The invention is intended to eliminate these disadvantages and to provide a relamatrix which constitutes a simple and compact coupling means lamped for electronic control. The invention can be characterized in particular by a relay polarizing magnetic system, which comprises a number of parallel permanent magnets provided with parallel plates arranged in two parallel planes by said permanent magnet magnets, which rails challenge pole shoes of magnetic material, wherein the permanent magnets arc so that in each plane every other rail has South Pole, every other North Pole magnetization, in that each of, said relays includes a parallel rued permanent magnets- DupL at. 21 a3: 22 / na, between the said planes arranged winding vessels of a material with two stable states of remanent magnetism, wherein each spirit of said vessels is coated in an opening between two rails in each plane, and of means at the spirits of said vessels are arranged spheres of magnetic material.

Relamatrisens kontaktsystern innefattar dels sagda skenor och kulor dels ett antal vinkelratt 'not sagda skenor fOrlopande kontakthand av metall, som vart och ett ar anordnat att tacka mot ena planet vanda andytor hos ett antal av sagda relakarnor och pa vilka kontaktband sagda kulor aro anordnade att kunna rulla. The contact system of the relamatrix comprises said rails and balls and a number of perpendicular 'not said rails extending contact hand of metal, each of which is arranged to abut one plane at the end faces of a number of said rela cores and on which contact bands said balls are arranged to be able to roll.

Uppfinningen skall narmare beskrivas med hj alp av ett utforingsexempel under hanvisning till bifogade ritning, pa vilken fig. 1 visar i schematisk form en relamatris I plan.vy, fig. 2 visar en sidovy nv samma anordning och fig. 3 en annan sidovy, i vilken dock permanentmagneternas karnor ntelaranats f Or att ge en tydligare bild av relakarnorna, varjamte fig. 4 visar ett enstaka rela i nagot starre skala. I figurerna 2-4 ha lindningarna kring relakarnoma endast antytts i synabolisk form; hur lindningarna inlaggas 1 matrisen visas i figurerna -7. The invention will be described in more detail with the aid of an exemplary embodiment with reference to the accompanying drawing, in which Fig. 1 shows in schematic form a relamatrix in plan view, Fig. 2 shows a side view of the same device and Fig. 3 another side view, in which, however, the nuclei of the permanent magnets are ntelaranats f Or to give a clearer picture of the rela cores, and Fig. 4 shows a single rela on a somewhat larger scale. In Figures 2-4, the windings around the rela cores have only been indicated in synabolic form; how the windings are inserted in the matrix is shown in figures -7.

Den i fig. 1 visade matrisen innefattar 24 st. relaldrnor 1 av ett bistabilt remanentmagnetiskt material. Relakarnorna are ordnade rader och kolumner, dar varje rad innehaller 4, varje kolumn 6 karnor. FOr polarisering av relaerna arc an.ordnade ett antal permanentmagneter 2, som var och en are forsedda med ett par langstraekta polskor 3 av magnetiskt material. The matrix shown in Fig. 1 comprises 24 pcs. relaldrnor 1 of a bistable remanent magnetic material. The rela cores are ordered rows and columns, where each row contains 4, each column 6 cores. For polarization of the relays arc arranged a number of permanent magnets 2, each of which is provided with a pair of elongate pole shoes 3 of magnetic material.

F'ermanentmagneter 'Deli polskor aro sa pla- 22O2371 cerade, att polskorna ligga parallellt med varandra utefter .karrtraderna, och att pa vardera sidan av matrisen varannan polsko har nordpols- varannan sydpolsmagnetisering. Aystandet mellan polskorna aro huvudsakligen lika med karnornas diameter, och karnornas findytor ligga mitt for Oppningarna mellan polskorna (se fig. 3 och 4). P'ermanent magnets' Deli pole shoes are so placed that the pole shoes lie parallel to each other along the rows of vessels, and that on each side of the matrix every other pole shoe has a north pole and every other south pole magnetization. The gap between the pole shoes is substantially equal to the diameter of the beads, and the fine surfaces of the beads lie opposite the openings between the pole shoes (see Figs. 3 and 4).

Utmed varje karnkolumn är ovanpa rel.& karnornas andytor inunder polskorna anordnat ett kontaktband 4 av metall. Pa dessa kontaktband finnes utanfOr varje andyta hos relakarnorna en kula 5 ay mjukmagnetiskt material. Matrisens kontaktsystem utgOres dels av de fast anordnade polskorna och kontaktbanden, vilka are isolerade fran permanentmagneterna och relakarnorna och givetviso aven frau varandra, och dels av kulorna, som under paverkan av karnornas dragningskraft alltid sta i elektriskt ledande kontakt med respektive kontaktband och, alltefter relakarnans magnetiseringsriktning, ligga intill -den ena eller andra av narliggande polskor. Samtliga polskor aro pa sin ena sida forsedda med ett isolerande .skikt 6, mot vilket kulorna relaernas overksamma lage anligga. Along each core column, a contact band 4 of metal is arranged on top of the rel. & The core surfaces of the core below the pole shoes. On these contact bands there is a ball 5 of soft magnetic material outside each face surface of the relay cores. The contact system of the matrix consists partly of the fixed pole shoes and contact bands, which are insulated from the permanent magnets and rela cores and of course also from each other, and partly of the balls, which under the influence of the grains' gravity are always in electrically conductive contact with the respective contact bands. , lie next to -the one or the other of nearby pole shoes. All pole shoes are on one side provided with an insulating layer 6, against which the idle layers of the relays abut.

- De enskilda relaerna fungera pa foljande satt (se fig. 4). Da relakarnans nedre ande har nordpols_ och doss ovre sydpolsmagnetisering, sluter sig faltet fran den Ovre vanstra polskon, soni har nordpolsmagneisering, genom rel5karnan till den nedre vanstra p01-slum. Relaets bada kulor attraheras da av det vanstra polskoparet och komma darigenom att anligga mot dessa polskors isolerade sida. Kraftfaltet sluter sig genom kulorna och rela, karnan, varyid faltet fran det hogra polskoparet undantranges fran relakarnan. Om relakarnan ommagnetiseras av en strompuls genom dess lindning, sa att karnans Ovre ande far nordpols- och dess nedre ande sydpolsmagnetisering, rulla kulorna Over till det med streckade linjer angivna laget, dar de sluta kontakt mellan kontaktbanden och det hogra polskoparet. Kraftfaltet sinter sig fran nedre hogra polskon till den Ovre hogra genom kulorna och relakarnan, varvid faltet mellan den. Owe och den nedre vanstra polskon undantranges, fran relalarnan. - The individual relays work in the following way (see fig. 4). Since the lower spirit of the relacarn has north pole_ and doss upper south pole magnetization, the field closes from the upper left pole shoe, soni has north pole magnetization, through the rel5karnan to the lower left p01 slum. The bath balls of the relay are then attracted by the left-hand pole pair and thereby come to rest against the insulated side of these pole crosses. The force field closes through the balls and the relay, the core, varies, the field from the right pole pair is displaced from the relay core. If the rela nucleus is re-magnetized by a current pulse through its winding, so that the upper spirit of the nucleus is north pole and its lower spirit south pole magnetization, the balls roll over to the layer indicated by dashed lines, where they stop contact between the contact bands and the right pole pair. The force field sints from the lower right pole of the pole to the upper right through the balls and the relay core, the field between it. Owe and the lower left wrist shoe are excluded, from the relalar.

Relamatrisens lindningar utfOras sa, att de enskilda relaerna kunna paverkas genom s. k. »additiy koincidens». Varje karnrad respektiye varje koltimn Or fOrsedd med en lindning, soni omfattar sarntliga relakarnor i raden respektiVe kolumnen_ sasom visas i fig. 5. F6r ommagnetisering av en. viss relakarna fordras "att strom samtidigt flyter i samma riktning runt karnan genom de hada lindningar, som omsluta karnan ifra.ga, dvs. genom Oval radlindningen sonikohinmlindningen, mom vilka karnan befinner sig. Ovriga relaer i ifragavarande rad eller kolumn ommagnetiseras, daryid ej, enar de ju endast paverkas av strom genom en lindning. The windings of the relamatrix are made so that the individual relays can be affected by so-called "additiy coincidence". Each core row and each carbon hour Or is provided with a winding, soni comprising special relay cores in the row or column_ as shown in Fig. 5. For the magnetization of a. if the relays are required "that current simultaneously flows in the same direction around the karnan through the hada windings, which enclose the karnan ifra.ga, ie through the oval row winding sonikohinmlindningen, mom where the karnan is located. Other relays in the row or column in question are magnetized, daryid not, they are only affected by current through a winding.

Enar varannan polsko har nordpols-, varannan sydpolsmagnetisering (se fig. 1) Or magnetiseringsriktningen for tillslag av relaerna olika i beroende av om karnorna ligga i karnrader med udda eller jamna ordningsnummer. Onskar man med sanama strOmriktning i en kolumnlindning kunna astadkomma tillslag av ett rela i kolumnen oberoende ay dess placering i ena eller andra raden, utforas lindningarna sa som visas i fig. 6. One every other pole shoe has north pole, every other south pole magnetization (see fig. 1) Or the magnetization direction for switching on the relays is different depending on whether the cores are in rows of cores with odd or even sequence numbers. If it is desired with the same current direction in a column winding to be able to effect a relay in the column regardless of its location in one or the other row, the windings are made as shown in Fig. 6.

Vid lindningar for »additiv koincidens» Or det av vikt att bade rad- och kolumnlindningar Ore jamnt f5rdelade langs relakarnornas hela langd. Delta ernas yid uppfinningen genom att saval rad- som kolumnlindningar aro uppdelade i ett antal dellindningar, var och en med ett litet antal, foretradesvis ett vary, och att dellindaingar tillhorande karniader respektiye kolumn.er Ore inlagda vaxelvis tangs karnornas axelriktning. I fig. 7 visas salunda den yttersta karnraden i relamatrisen med sin radlindning 7 och koluinnlindningar 8. En sadan lindning kan latt utforas formedelst en maskin, som vaxelvis inlagger dellindningar tillhorande karnraderna och dellindningar tillhorande kolumnerna. Man kan sedan, om man sa onskar, ingjuta hela Enduing-en, eventuellt tillsammans med karnorna, 1 ett hardbart harts. In the case of windings for "additive coincidence", it is important that both row and column windings are evenly distributed along the entire length of the relays. The invention relates to the invention in that both row and column windings are divided into a number of sub-windings, each with a small number, preferably a vary, and that sub-windings belonging to the carniads or columns are interposed alternately along the axis direction of the cores. Fig. 7 thus shows the outermost core row in the relamatrix with its row winding 7 and column windings 8. Such a winding can be easily performed by means of a machine which alternately inserts sub-windings belonging to the row rows and sub-windings belonging to the columns. You can then, if you wish, inject the whole Enduing, possibly together with the kernels, into a hardenable resin.
