Ovaj pronalazak ima za cilj da otkloni te teškoče, i u tu svrhu sadrži bobinu za paljenje motora sa unutrašnjim sagnrevanjem tipa koji sadrži: izolaciono ku'ište u koje su koncentrično smešteni,oko jedne grane zatvorenog magnetnog lola,ava namotaja primakni i sekundarni,i nosač koji sadrži priključke niskog i visoKOg napona,a naznačen je time da nosač sadrži sredstva za pozicionisanje i za držanje dvaju namotaja pre njihovog montiranja u kučište.The present invention is intended to remedy these difficulties and for this purpose contains an ignition coil for an internal combustion engine of the type comprising: an insulating housing in which they are concentrically housed, about one branch of a closed magnetic louv, a coil close and secondary, and a carrier containing low and high voltage terminals, characterized in that the carrier comprises means for positioning and holding the two windings before mounting them in the housing.

Sledeči opis,zajedno sa priloženim crtežima pomoči če da se bolje shvati kako može da se realizuje pronalazak.The following description, together with the accompanying drawings will help to better understand how the invention can be realized.

Sl.l prikazuje presek bobine za paljenje prema pronalasku.Fig. 1 shows a cross-section of the ignition coil according to the invention.

S1.2a i 2b predstavljaju nosač prema oronalasku,opremljen sa električnim priključnic.ama niskog i visokog napona.S1.2a and 2b are a carrier-mounted carrier equipped with low- and high-voltage electrical connectors.

Sl.3 prikazuje nosač primarnog namotaja za bobinu za paljenje prema pronalasku.Fig. 3 shows a carrier of the primary ignition coil coil according to the invention.

S1.4a i 4b predstavljaju nosač aa sekundarni namotaj prema pronalasku.S1.4a and 4b represent carrier aa a secondary winding according to the invention.

Bobina za paljenje koja je predstavljena na sl.l sastoji se na poznati način od kučišta 1 koje drži jedan nosač 13 na koji je namotan primarni namotaj 4,i nosač 15 na koji je namotan sekundarni namotaj 3,izolovane od zatvorenog magnetnog kola 2 kojeg sačinjava paket iscčenih(štancovanih) limova,sečenih u odgovarajučem obliku,i koncentrične sa jednom od grana pom.magnetnog kola. Na gornjem delu kučišta 1,nosač 5 nosi priključke niskog napona 6, i izlaz visokog napona 7·The ignition coil shown in FIG. 1 consists in a known manner of a housing 1 held by a carrier 13 to which a primary winding 4 is wound, and a carrier 15 to which a secondary winding 3 is wound, isolated from the closed magnetic circuit 2 of which it is formed. a package of stamped sheets, cut in a suitable shape, and concentric with one of the branches of the pom-magnetic circuit. On the upper part of the housing 1, the carrier 5 carries the low voltage terminals 6, and the high voltage output 7 ·

Prema pronalakku nosač 5 sadrži,od istog materijala,sredstva za pozicionisanje i za držanje namotaja 3 i 4.According to the invention, the carrier 5 comprises, from the same material, positioning and holding means 3 and 4.

Za primarni namotaj 4 ta su sredstva sačinjena od dva otvora 9 u koja se postavljaju dva Štifta 11 koja su ostvarena na gornjem delu nosača 13 namotaja 4,i žljeb lo u kojem kliza šapa 12 koja može elastično da se deformiše,a koja na svome slobodnom kraju ima kuku 12a i doK je kuka 12a slobodna,ova se oslanja na gornju stranu 5a nosača 5 obezbedujuči tako vezu izmedu nosača 5 i nosača 13-Ta šapa 12 je paralelna sa dva Štifta 11. Nosač 13,te stoga i namotaj 4 se postavljaju uklapanjem štiftova 11 sa otvorima 9, a drže se spajanjem jezička 12 i njegove kuke 12a za žljeb lo i za ojačanje 5a.For the primary winding 4, these means are made up of two openings 9 into which are placed two pins 11 which are formed on the upper part of the carrier 13 of the winding 4, and a groove in which a sliding paw 12 which can be elastically deformable and which is free end has hook 12a and while hook 12a is free, this rests on the upper side 5a of carrier 5 thus providing a connection between the carrier 5 and the carrier 13. That paw 12 is parallel to the two pins 11. The carrier 13, and therefore the winding 4 is mounted by integrating the pins 11 with the openings 9, and are held together by connecting the tab 12 and its hook 12a for the groove lo and for reinforcement 5a.

Za sekundarni namotaj 3 sredstva za držanje i pozicionisanje su sačinjena od dve šape 14,elafetično deformišuce,koje su realizovane na unutarnjoj strani nosača 5 a svaka od njih ima spoljne rebro 14a na svome slobodnom kraju.Te šape 14 saraduju sa unutarnjom šupljinom nosača 15 sekundarnog namotaja 3«Taj nosač 15 ima cilindričan unutarnji oblik,a spolja sadrži veči broj prstenastih komora u koje se namotava sekundarni namotaj 3· Dva ureza 15b su urezana u unutrašniosti nosača 15 tako da se ostvare oovršine 15a na koje ^;e se oslanjati rebra 14a šapa 14.For the secondary winding 3, the holding and positioning means are made of two paws 14, elastically deformable, which are realized on the inside of the carrier 5 and each of them has an outer rib 14a at its free end. These paws 14 cooperate with the inner cavity of the carrier 15 of the secondary winding 3 "This carrier 15 has a cylindrical inner shape and externally contains a number of annular chambers into which the secondary winding 3 is wound ^. will be supported by the paws 14a of the paw 14.

Osim toga,nosač 15 je opremljen sa jedne strane sa pro-vodnom vezom 8 od četvrtaste žice koja obezbeduje dovod struje za napajanje sekundarnog namotaja 3 čiji je jedan kraj omotan oko jednoga kraja četvrtaste žice 8,a sa druge strane sa jednom drugom provodnom vezom sa četvrtastom žicom 16 oko jednog od krajeva koje je obmotan drugi kraj sekundarnog namotaja 3,a čiji je drugi kraj 16a u obliku prstena.In addition, the bracket 15 is provided on one side with a conductive connection 8 of square wire that provides a supply of current to power the secondary winding 3 whose one end is wrapped around one end of the square wire 8 and on the other side with another conductive connection with a square wire 16 about one of the ends wrapped around the other end of the secondary winding 3 and whose other end 16a is ring-shaped.

Ovi razni elementi dozvoljavaju da se ostvari predsklapanje u cilju olakšanja skladištenja i manipulacije kod definitivnog sklapanja.U stvari nosač 5 može lako da bude opremljen sa različitim priključcima 6 koje sačinjavaju u našem primeru provodne metalne trake koje su savijene,ili sa provodnikom izvučenim:od priključka 7;od primarnog namotaja 4 koji je držan i pozicionisan sa napred opisanim elementarna a čije električne veze su ostvarene sa odgovarajucim priključkom 6;sekundarnog namotaja 3 držanog uskakanjem rubova 14a šapa 14 na površine -.-15^ nosača 15,precizno pozicionisanje toga namotaja 3 se ostvaruje prilikom lemljenja priključka četvrtaste žice 8 sa drugim priključkom 6 za dovod struj e,a veza izmedu prstena 16a i priključka visokog napona 7 putem izžljebljenog klina 17 utisnutog pod pritiskom u pom.priključak 7·These various elements allow for pre-assembly to facilitate storage and manipulation of the definitive assembly. In fact, the carrier 5 can easily be equipped with various terminals 6 which, in our example, are conductive metal strips that are bent, or with conductors drawn: from the connector 7; from the primary winding 4 which is held and positioned with the elementary described above and whose electrical connections are made with the corresponding terminal 6; is made by soldering the square wire connection 8 with the second power supply terminal 6, and the connection between the ring 16a and the high voltage terminal 7 via a grooved pin 17 pressed into pressure in the auxiliary terminal 7 ·

Kod ove realizacije nosač 5 sadrži zaštitnu pregradu 18 od izolujučeg materijala,koja izoluje priključke 6 i zatvoreno magnetsko kolo 2.In this embodiment, the carrier 5 comprises a protective barrier 18 of insulating material, which insulates the terminals 6 and the closed magnetic circuit 2.

Taj nosač 5 takode sadrži od istog materijala prolaz 19 u koji je postavljen priključak visokog napona 7,a na njegovim prilazima se nalaze prsti 2o koji mogu da drže zaštitnik kabla,koji nije prikazan.This carrier 5 also contains a passage 19 into the same material, into which a high voltage connector 7 is mounted, and there are fingers 2o at its approaches that can hold the cable protector, which is not shown.

Zahvaljujuci tim raznim sredstvima nosač 5,priključci 6,7 i namotaji 3 i 4 sačinjavaju autonoman sklop što smanjuje broj delikatnih manipulacija sklapanja raznih elemenata u kučište 1 oko grane magnetnog kola 2.Thanks to these various means, the carrier 5, the connections 6,7 and the windings 3 and 4 form an autonomous assembly which reduces the number of delicate manipulations of assembling various elements into the housing 1 around the branch of the magnetic circuit 2.
