Description

Uppfinnare: H V Alexandiersson Foreliggande uppfinning avser en lindning for relamatriser, dar relaerna aro ordnade i rader och kolumner och varje rad resp. kolumn ar forsedd med en individuell magnetiseringslindning, sa att ett godtyckligt rela kan paverkas genom samtidig strom genom magnetiseringslindningarna for raden och kolumnen, i vilka relaet ligger. Inventor: H V Alexandiersson The present invention relates to a winding for relamatrices, where the relays are arranged in rows and columns and each row resp. column is provided with an individual excitation winding, so that an arbitrary relay can be affected by simultaneous current through the excitation windings for the row and column in which the relay is located.

Vid dylika lindningar är det ay vikt att hada magnetiseringslindningarna aro i mojligaste man jamnt fOrdelade utefter relakarnornas hela langd, speciellt da det ror sig am karnor av ett histabilt remanentmag,netiskt material. Vid de kanda lindningarna av detta slag are de bada magnetiseringslindningarna vid varje karna anordnade som tva utefter karnans langd utbredda spolar, av vilka den ena ligger utanpa den andra. Detta innebar olagenheten av en relativt klurapig och dyrbar konstruktion, vilken olagenhet undvikes yid uppfinningen genom att varje magnetiseringslindning Or uppdelad i ett antal dellindningar, var och en med ett litet antal, foretradesvis ett vary, och att dellindningar tillhorande karnrader °eh_ karnkolumner are inlagda vaxelvis langs karnornas axelriktning. In the case of such windings, it is important to have the excitation windings as evenly distributed as possible along the entire length of the rela cores, especially when the cores are of a histable remanent stomach, netic material. In the known windings of this kind, the two magnetizing windings at each core are arranged as two coils spread along the length of the core, one of which lies on top of the other. This entailed the inadequacy of a relatively intricate and expensive construction, which inertia is avoided by the invention in that each magnetizing winding Or is divided into a number of sub-windings, each with a small number, preferably a vary, and that sub-windings belonging to core rows along the axis direction of the beads.

Uppfinningen skall nedan narmare beskrivas med hjalp ay ett utfOringsexempel avseende en lindning for en relamatris med polariserade relaer under hanvisning till bifogade ritning, pa vilken fig. 1 visor i schematisk form en relamatris i planvy, fig. 2 och 3 visa tva. olika sidovyer ay relamatrisen, varjamte fig. 4 visar ett enstaka rela i nagot storre skala. I figurerna 2-4 ha lindningarna kring relakarnorna endast antytts i symbolisk form; hur lindningarna inlaggas i matrisen visas i figurerna 5-7. The invention will be described in more detail below with the aid of an exemplary embodiment concerning a winding of a relamatris with polarized relays with reference to the accompanying drawing, in which Fig. 1 shows in schematic form a relamatris in plan view, Figs. 2 and 3 show two. different side views ay the relamatrix, 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 symbolic form; how the windings are inserted into the matrix is shown in Figures 5-7.

Den 1 fig. 1-3 Asada matrisen innefattar Dupl. kl. 21 a3: 22/10; 21 a3: 61/ 24 st. relakarnor av ett bistabilt remanentmagnetiserat material. Relakarnorna aro ordnade i rader och kolumner, dar varje rad innehaller 4, varje kolumn 6 karnor. FOr polarisering av relaerna aro anordnade ett antal permanentmagneter 2, som var och en aro forsedda med ett par langstrackta polskor 3 av magnetiskt material. The 1 Fig. 1-3 Asada matrix includes Dupl. at 21 a3: 22/10; 21 a3: 61/24 st. relay cores of a bistable remanent magnetized material. The rela cores are arranged in rows and columns, where each row contains 4, each column 6 cores. For polarization of the relays aro arranged a number of permanent magnets 2, each of which is provided with a pair of elongate pole shoes 3 of magnetic material.

Permanentmagneter och polskor Oro sa placerade, att polskorna ligga parallellt med varandra utefter karnraderna, och att pa vardera sidan av matrisen Yarannan palsko har nordpals-, varannan sydpolsmagnetisering. A_vstandet mellan polskurna Or hu-vudsaldigen lika med karnornas diameter, och karnornas andytor ligga mitt for oppningarna mellan palskorna (se fig. 3 och 4). Permanent magnets and pole shoes Oro is so placed that the pole shoes lie parallel to each other along the rows of cores, and that on each side of the matrix Yarannan palsko has north pole, every other south pole magnetization. The distance between the pole cuts is generally equal to the diameter of the grains, and the end faces of the grains lie in the middle of the openings between the grains (see Figs. 3 and 4).

Utmed varje karnkolumn är ovanpa relakarnornas andytor inunder polskorna anordnat ett kontakthand 4 av metall. P0. dessa kontaktband finnes utanfor varje andyta hos re15.karnorna en kula 5 av mjukmagnetiskt material. Matrisens kontaktsystem utgores •dels ay de fast anordnade polskorna och kontaktbanden, vilka Oro isolerade fran permanentmagneterna och relakarnorna och givetvis aven fran varandra, och dels av kulorna, som under paverkan av karnornas dragningskraft alltid std I elektriskt ledande kontakt med respektive kontaktband, och, alltefter relakarnaris magnetiseringsriktning, ligga intilr den ena eller andra av narliggande polskor. Samtliga polskor Oro pa sin ena sida fOrsedda med ett isolerande skikt 6, mot yilket kulorna i relaernas overksamma lage anligga. Along each core column, a contact hand 4 of metal is arranged on top of the end surfaces of the relay core under the pole shoes. P0. these contact bands are located outside each surface of the re15 cores a ball 5 of soft magnetic material. The contact system of the matrix consists • partly of the fixed pole shoes and contact bands, which Oro 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 gravitational pull always remain in electrically conductive contact with the respective contact bands, and, accordingly relacarnaris magnetization direction, lie adjacent to one or the other of adjacent pole shoes. All pole shoes On one side are provided with an insulating layer 6, against which the balls in the inactive layer of the relays abut.

De enskilda relaerna fungera pa foljande satt (se fig. 4). Da relakarnans nedre ande har nordpols- och dess, owe sydpolsmagnetisering, sinter sig faltet fran den ovre vanstra 2 polskon, som har nordpolsmagnetisering, genom relakarnan till den nedre vanstra polskon. 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 relakarnan, varvid fillet fran det hogra polskoparet undantrames fran relakarnan. Om relakarnan ommagnetiseras av en str8mpuls genom dess lindning, sâ att karnans ovre dude far nordpols- och dess, nedre ande sydpolsmagnetisering, rulla kulorna over till det med streekade tinier angivna laget, dar de sluta kontakt mellan kontaktbanden och det hogra polskoparet. Kraftfaltet sinter sig frau nedre hogra polskon till den Owe hOgra genom kulorna och relakarnan, varvid fillet mellan den 8vre och den nedre vanstra polskon undantranges fran relakarnan. The individual relays work in the following way (see Fig. 4). Since the lower spirit of the rela core has the north pole and its, owe south pole magnetization, the field sints from the upper left 2 pole shoe, which has north pole magnetization, through the rela core to the lower left pole shoe. 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 rela core, whereby the fillet from the right pole pair is removed from the rela core. If the rela nucleus is re-magnetized by a current pulse through its winding, so that the upper dude of the nucleus receives the 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 shoe to the Owe right through the balls and the rela core, the fillet between the 8th and the lower left pole shoe being displaced from the rela core.

Relamatrisens lindningar utforas sa, att de enskilda relaerna kunna paverkas genom S. k. »additiv koincidens». Varje karnrad respektiye varje koluxnn dr forsedd med en. magnetiseringslindning, som omfattar samtliga reldkarnor i raden resp. kolumnen, sasom visas i fig. 5. For ommagnetisering av en viss Feldkarna fordras att strOm samtidigt flyter i samma riktning runt karnan genom de bada magnetiseringslindningar, som omsluta kdr-nan ifraga, dvs. genom saval radlindningen som kolumnlindningen, Mom vilka karnan befinner sig. Ovriga relder i ifragavaran.de rad kolumn ommagnetiseras darvid ej, endr de ju endast paverkas av strom genom en magnet's eringslindning. The windings of the relamatrix are designed so that the individual relays can be affected by so-called "additive coincidence". Each row of vessels, respectively, each column is provided with one. excitation winding, which comprises all the core cores in the row resp. the column, as shown in Fig. 5. For re-magnetization of a certain field core, current is required to flow simultaneously in the same direction around the core through the two magnetizing windings, which enclose the core, i.e. through the saval line winding as the column winding, Mom which the core is located. The other coils in the row column in question are not re-magnetized, since they are only affected by current through a magnet's winding.

Enar varannan polsko bar nordpols-, varannan sydpolsmagnetisering (se fig. 1) ar magnetiseringsriktningen for tillslag av relaerna olika i beroende nv om karnorna ligga i Urnrader med udda eller jamna ordningsnummer. Onskar man med samma strontriktning i en kolumnlindning kunna astadkomma tillslag av ett rela i kolumnen oberoende av dess placering i ena eller andra raden, utforas lind ningarna sa som visas i fig. 6, ddr kolumnlindningarnas tradar aro korsade i Oppning7 arna radian karnorna, sa att I varje kolumn lindningen yaxelvis gar i medsols- och motsols riktning runt karnorna i kolumnen. I fig. 7 visas den yttersta karnraden i relamatrisen med. radlindning 7 och kolumnlindningar 8. Lindningen i sin helhet kan latt utforas fOrmedelst en maskin, som vaxelyis inlagger dellindningar tillhorande karnraderna och dellinclningar tillhorande kolumnerna. Om sa onskas kan man ingjuta hela lindningen, eventuellt tillsaramans med karnorna, i ett hardbart harts, varvid man erhaller ett block, pa vilket kontaktbanclen, permanentmagneterna och polskorna monteras. One every other pole shoe carried North Pole, every other South Pole magnetization (see Fig. 1) the direction of magnetization for switching on the relays is different depending on whether the cores are in Urnrader with odd or even sequence numbers. If it is desired to be able to effect a relay in the column with the same string direction in a column winding, regardless of its location in one or the other row, the windings are made as shown in Fig. 6, where the columns of the column windings are crossed in In each column, the winding axially rotates clockwise and counterclockwise around the cores in the column. Fig. 7 shows the outermost row of vessels in the relamatrix with. row winding 7 and column windings 8. The winding in its entirety can be easily carried out by means of a machine which, in wax, inserts sub-windings belonging to the rows of cores and sub-windings belonging to the columns. If desired, the entire winding, possibly together with the cores, can be cast in a hardenable resin, whereby a block is obtained, on which the contact beam, the permanent magnets and the pole shoes are mounted.
