Priključna spenjalna naprava, posebno za dušilke ali transformatorjeCoupling device, especially for chokes or transformers
Izum se nanaša na priključno spenjalno napravo, posebno za dušilke ali transformatorje, s spenjalnim ohišjem, sestoječim iz izolacijskega materiala, ki ima izreze za priključne žice, ter najmanj enim, v spenjalno ohišje vstavljenim kovinskim spenjalnim vložkom, ki je izoblikovan kot vijačna sponka s priključno izvrtino, ki se nahaja v masivnem telesu sponke in je namenjena sprejemu priključnih žic, in spenjalnim vijakom, ki se lahko uvije v ustrezno navojno izvrtino, ki vodi v priključno izvrtino.The invention relates to a coupling device, especially for inductors or transformers, with a coupling housing consisting of insulating material having cutouts for connecting wires and at least one metal coupling insert inserted into the coupling housing, which is formed as a screw terminal a hole in the solid body of the buckle for receiving the connecting wires, and a clamping screw that can be screwed into a suitable threaded hole leading to the connecting hole.
Dušilke ali majhni transformatorji, ki so uporabljeni npr. kot predpriključne priprave za plinske sijalke, se opremijo pri proizvajalcu s spenjalno napravo, ki omogoča povezavo zunanjih priključnih žic s konci navitja. Ker so takšne dušilke in majhni transformatorji masovni izdelki, ki se izdelujejo v velikem številu ob naraščajoči uporabi avtomatskih delovnih potekov, ima tudi racionalna možnost izdelave in montaže spenjalne naprave občuten pomen. Po drugi strani pa mora biti v vsakem primeru zagotovljena električno brezhibna, v obratovanju zanesljiva povezava med zunanjimi priključnimi žicami in konci navitja.Chokes or small transformers used e.g. as pre-connection devices for gas lamps, the manufacturer shall be provided with a clamping device to allow the connection of external connecting wires to the winding ends. Because such chokes and small transformers are mass-produced products in large numbers with the increasing use of automatic workflows, the rational ability to manufacture and install a coupler is of considerable importance. On the other hand, an electrically faultless, reliable connection between the external connecting wires and the winding ends must be ensured in each case.
Iz nemškega patentnega spisa 22 44 158 je znana prednostno kot predpriključna priprava za plinske sijalke namenjena dušilka, pri kateri je spenjalna naprava izoblikovana po načinu lestenčne sponke, ki je pritrjena na montažni tračnici, ki nosi paket pločevine. Razporeditev je pri tem izbrana tako, da so glave navitij dušilke prekrite z enodelnimi, na magnetno jedro nalegajočimi ohišji iz izolacijske snovi, ki so pritrjena na paketu pločevine s pomočjo prioblikovanega, v vmesni prostor med jedrom magneta in vsakokratno glavo navitja vrinjenega jezika in ki nosijo na svoji zunanji steni, ki leži nasproti glavi navitja, prioblikovane, spodaj preklane kose cevi, ki trdno oklepajo konce žic navitja. Lestenčna sponka je potisnjena enostransko na te končne tulke kabla in je s temi speta prek pripadajočih spenjalnih vijakov. Položaj lestenčne sponke je lahko fiksiran z nosom na ohišju.According to German patent application 22 44 158, it is known, preferably, as a pre-attachment device for gas lamps, a dedicated damper, in which the coupling device is formed in the manner of a chandelier clamp attached to the mounting rail carrying the sheet metal package. The arrangement is chosen in such a way that the winding coil heads are covered with one-piece magnetically-core insulated housing housings, which are secured to the sheet metal package by means of a molded, in-between space between the core of the magnet and the respective winding tongue head and carrying on its outer wall opposite to the head of the winding, pieces of pipe formed below, curved below, which firmly encircle the ends of the winding wires. The chandelier clip is pushed unilaterally to these end cable sleeves and is secured to the end via the associated clamping screws. The position of the chandelier clip can be fixed with the nose on the case.
To izoblikovanje priključne spenjalne naprave je zaradi kabelskih končnih tulk, ki se pritisnejo na omenjene cevne kose, in zaradi lestenčne sponke, ki jo je treba posebej montirati, sorazmeroma drago in časovno zamudno. Lestenčna sponka, ki je nameščena pred ohišjem v obliki kape, ki izolira pripadajočo glavo navitja, nujno podaljša gradbeno dolžino celotne priprave, kar je nezaželeno za vrsto primerov uporabe, npr. takrat, kadar mora biti takšna dušilka kot predpriključna priprava za plinsko sijalko nameščena v svetilki.This design of the coupling device is relatively expensive and time-consuming because of the cable end sleeves that are pressed against said tubing pieces and because of the chandelier that needs to be mounted separately. A chandelier clamp mounted in front of a cap-shaped housing that isolates the associated winding head necessarily extends the construction length of the entire device, which is undesirable for a number of use cases, e.g. when such a damper as the pre-attachment for the gas lamp must be installed in the lamp.
Bistveno bolj ugodni pogoji glede povečave zunanjih izmer celotne priprave, ki je povzročena s priključno spenjalno napravo, in stroškovno ugodne izdelave pri preprosti montaži nastopajo pri dušilki ali majhnem transformatorju, kot je znan npr. iz nemškega patentnega spisa 33 09 108. V tem primeru je priključni spenjalni del izoblikovan v obliki letve z dvema s tankim mostičem medsebojno povezanima spenjalnima elementoma v obliki bloka, pri čemer so spenjalni elementi, ki obsegajo priključne sponke, nameščeni ležeče v stranskim področjih poleg zunanje stene kot ohišje oblikovanega oblikovanca iz izolacijske snovi, ki prekriva pripadajočo glavo navitja, s prek njegove zunanje stene raztezajočim se mostičem. Priključni spenjalni del se lahko zaskoči z oblikovancem iz izolacijske snovi ali prekrivno kapo. Ker so priključne sponke izvedene kot vijačne sponke z masivnim kovinskim spenjalnim telesom s prehodnimi priključnimi izvrtinami in s spenjalnimi vijaki za priključne žice navitja, ki se vstavljajo v priključne izvrtine, je montaža te spenjalne naprave za masovno proizvodnjo dušilk še vedno zahtevna. Tako je potrebno namreč uvesti priključne žice navitij, t.j. konce navitij, najprej v pripadajoče priključne izvrtine vijačnih sponk, preden se lahko priključni spenjalni del montira in spenjalni vijaki, ki so dodeljeni koncem navitij, zateg4 nejo. Razen tega je možna montaža priključnega spenjalnega dela šele po zaključeni impregnaciji dušilke ali transformatorja, ker bi se drugače spenjalni vijaki, ki so uporabljeni za priključitev zunanjih priključnih žic, zlepili in se jih ne bi moglo več uporabljati,Significantly more favorable conditions for increasing the external dimensions of the entire device caused by the coupling device and the cost-effective fabrication of the simple actuation are with a choke or small transformer, as is known, for example. in German patent file 33 09 108. In this case, the connecting coupling portion is formed in the form of a lath with two thin bridge interconnected block-shaped connecting elements, the coupling elements comprising the connecting terminals being positioned in lateral areas adjacent to the outer the walls as a housing of a molded insulating material covering the associated winding head, with a bridge extending beyond its outer wall. The connecting coupling can be secured with an insulating material or a cover cap. Since the terminal blocks are designed as screw terminals with a massive metal clamping body with transitional connecting holes and with clamping screws for the winding connection wires inserted into the connecting holes, the installation of this clamp for mass production of chokes is still demanding. Thus, it is necessary to introduce winding connection wires, i.e. the ends of the windings, first into the corresponding connecting holes of the screw terminals, before the connecting clamping part can be mounted and the clamping screws assigned to the ends of the windings tighten. In addition, it is only possible to install the terminal coupling after impregnation of the choke or transformer, otherwise the clamping screws used to connect the external terminal wires would become stuck and could no longer be used,
Montažo električne priključne spenjaine naprave pred impregnacijo pa omogoča v nasprotju s tem iz vzhodno-nemškega patentnega spisa 103 087 znana dušilka, pri kateri se za izolacijo glav navitja uporabljajo kape iz izolacijske snovi, ki so s pomočjo prioblikovanega jezika zasidrane v vmesnem prostoru med glavo navitja in paketom pločevine. Kapa iz izolacijske snovi je podaljšana v vzdolžni smeri priprave z dodatno komoro, v kateri so nameščeni električni priključni elementi, ki se po impregnaciji in površinskem preslojenju razkrijejo z odstranitvijo prekrival, prioblikovanih na kapi. Prekrivala ščitijo kot vijačne sponke izoblikovane kovinske priključne elemente pred zlepljenjem z impregnacijskim materialom. Priključitev koncev navitja na priključne elemente zato ni preprosta, ker je treba uvesti priključne žice v priključne izvrtine priključnih elementov, ki ležijo v globini njim dodeljene komore, in jih je tam treba speti, razen v primeru, da bi se priključni elementi vtisnili v komoro šele po povezavi s konci navitja. To pa bi bilo manj smotrno že glede na nevarnost poškodbe tankih žic navitja. Razen tega poveča komora prekrivne kape, ki sprejme priključne elemente in ki je nameščena pred glavo navitja, aksialno dolžino gradnje celotne priprave.However, the installation of the electrical coupling of the device before impregnation is, however, enabled by the known German patent file 103 087, which uses caps for insulation of the winding heads which are anchored in the intermediate space between the winding head by means of a formed tongue. and a tin pack. The cap of the insulating material is extended in the longitudinal direction of the device with an additional chamber in which the electrical connecting elements are installed, which are revealed after impregnation and surface coating by removing the caps formed on the cap. The covers protect the screw-shaped terminals of the metal mounting element from bonding with the impregnation material. Therefore, it is not easy to connect the winding ends to the connecting elements, since it is necessary to insert the connecting wires into the connecting holes of the connecting elements that lie in the depth of the chamber assigned to them and to be soldered there, unless the connection elements are only pressed into the chamber. after connection to the winding ends. However, this would be less useful given the risk of damage to the thin coil wires. In addition, the cover cap chamber which receives the connection elements and which is mounted in front of the winding head increases the axial length of construction of the entire device.
V priključni tehniki so končno v uporabi tudi brezvijačne priključne sponke v različnih izvedbah. Pri znani priključni ali povezovalni sponki za električne vodnike, znani iz nemške objavljene patentne prijave 31 12 969, sta nameščeni v telesu iz izolacijske snovi tokovna tračnica in najmanj ena po načinu dročnika pomično uležajena spenjalna vzmet, ki je v stiku s tokovno tračnico in ki v naprej pomaknjenem položaju z dvema v U-obliki medsebojno nameščenima spenjalnima krakoma viličasto sega prek električnega vodnika in tvori za njim stik, pri čemer je električni vodnik voden v vodniškem ležišču, ki vodnik z vseh strani obdaja in ki je izoblikovano tako, da meji na obeh straneh na dročniško vzmet. Taka priključna ali povezovalna sponka ni zato brez nadaljnjega uporabna kot priključna spenjalna naprava za dušilko ali majhen transformator, ker ni primerna za to, da bi se lahko integrirala s pripravo v kompaktno gradbeno enoto. Tudi ni pogosto brez nadaljnjega možna povezava sorazmeroma tankih žic navitja z zunanjimi priključnimi žicami, ki imajo bistveno večji premer.Connection techniques also include screwless terminals in various designs. In the case of known connecting or connecting terminals for electrical conductors, known from German patent application 31 12 969, a power rail and at least one coupling spring in contact with the power rail are mounted in the body of the insulator. the forward displaced position with two U-shaped clamping arms extending through the electrical conductor and forming a contact therewith, the electrical conductor being guided in a conduit which surrounds the conductor on all sides and which is formed so that it borders on both sides. pages on the thruster spring. Such a connection or connection clip is therefore not without further use as a connection clamping device for a choke or a small transformer, since it is not suitable for being integrated with preparation into a compact construction unit. It is also not often possible to connect relatively thin winding wires to external connection wires that have a substantially larger diameter without further ado.
To velja tudi za brezvijačno sponko te vrste, ki je zna na iz ameriškega patentnega spisa 2501 187, ki obsega v glavnem votlo valjasto kovinsko spenjalno telo, katerega plašč ima stransko režo, tako da sta podana dva približno delno valjasta spenjalna kraka, ki omejujeta med seboj dve na robovih odprti, režasti odprtini. V notranjosti votlo valjastega spenjalnega telesa so nameščena nožasta rezila, ki omejujejo reže, katerih širina je manjša kot premer priključne žice, ki naj se sprejme tako, da se pri uvajanju z lakom izolirane priključne žice izo6 lacija z lakom prereže in se ustvari brezhibno električno kontaktiranje, ne da bi bilo potrebno predhodno snemanje izolacije s konca vodnika. Kovinsko spenjalno telo navzven ni izolirano in že iz tega razloga v tej obliki ni uporabno kot priključna naprava za predpriključno napravo ali transformator.This also applies to a screwless buckle of this type known from U.S. Patent No. 2501,187, which comprises a substantially hollow cylindrical metal coupling body, the jacket having a lateral slot, so that two approximately cylindrical coupling arms limiting between two open at the edges, slit openings. Inside the hollow cylindrical coupling body there are knife blades that limit the slots whose width is smaller than the diameter of the connecting wire, which should be adopted by cutting the insulation with the varnish and introducing flawless electrical contact when introduced with varnish. , without having to remove the insulation from the end of the conductor beforehand. The metal coupling body is not insulated externally and for this reason it is not suitable for use in this form as a pre-connection device or transformer.
Izhajajoč iz tega stanja tehnike ima izum za nalogo, da ustvari priključno spenjalno napravo, posebno za dušilke ali majhne transformatorje, ki omogoča pri preprosti izdelavi in časovno nezahtevni montaži posebno kratko, kompaktno gradbeno obliko priprav, ki so opremljene s takšno priključno spenjalno napravo.BACKGROUND OF THE INVENTION It is an object of the invention to create a coupling device, especially for chokes or small transformers, which enables a particularly short, compact construction of devices equipped with such a coupling device in the simple construction and time-consuming installation.
Za rešitev te naloge je uvodoma navedena priključna spenjalna naprava po izumu označena s tem, da ima spenjalni vložek na strani dna dva na medsebojnem razmiku potekajoče nameščena spenjalna kraka, ki nosita najmanj dva drug proti drugemu usmerjena nožasta kontakta, s katerima je omejena vsaj ena na robu odprta, režasta odprtina, katere širina je manjša od premera priključne žice, ki jo sprejme, da je spenjalno ohišje postavljeno na spodnji del iz izolacijskega materiala, ki prekriva vsaj spenjalni vložek in da je spenjalni vložek s svojim spenjalnim telesom vstavljen v spenjalno ohišje tesno proti spenjalnemu vijaku.In order to accomplish this task, the connection coupling device according to the invention is characterized by the fact that the coupling insert on the bottom side has two spaced joints, which have at least two mutually oriented contact blades with at least two mutually oriented contacts, which limit at least one of them. edge open, slotted opening whose width is smaller than the diameter of the connecting wire, which accepts that the clamping housing is mounted on the bottom of insulating material that covers at least the clamping insert and that the clamping insert with its clamping body is tightly inserted into the clamping body against the clamping screw.
Pri tej priključni tehniki se z namestitvijo spenjalnega ohišja na spodnji del s pripadajočih priključnih žic navitja samodejno odstrani izolacija in ustvari brezhiben kontakt. Ker je za zunanje priključne žice na razpolago normalen običajni vijačni priključek, se lahko gotova priprava pri uporabi insta7 lira na običajen način. Priključna mesta in priključna sredstva sorazmeroma tankih žic navitja in praviloma bistveno debelejši zunanjih priključnih žic na kovinskem spenjalnem telesu so medsebojno ločena; zato se lahko izvedejo glede na doseženje vsakokratno optimalnih priključnih okoliščin za žice navitja oz. zunanje priključne žice. Ker je spenjalni vložek s svojim spenjalnim telesom proti spenjalnemu vijaku vstavljen tesno v spenjalno ohišje, ne more prodreti pri impregnaciji v montiranem stanju nobeno tekoče impregnacijsko sredstvo iz notranjosti spenjalnega ohišja proti spenjalnemu vijaku in tega zlepiti. Končno dopušča spenjalno ohišje, ki se natakne preprosto na spodnji del in vsebuje spenjalni vložek, optimalno prilagoditev na vsakokratne prostorske danosti dušilke ali transformatorja, tako da je priključna spenjalna naprava primerna posebno za kompaktno, polno integrirano priključno tehniko za doseženje gradbenih oblik posebno kratke gradbene dolžine.In this connection technique, the insulation is automatically removed by attaching the coupling housing to the lower part of the associated winding connection wires and creating a faultless contact. Since a normal normal screw connection is available for external connection wires, the ready-to-use device can be used in the usual manner using insta7 lire. The connection points and connection means of relatively thin winding wires and, as a rule, substantially thicker outer connecting wires on the metal coupling body are separated from each other; therefore, they can be designed to achieve optimum connection conditions for the winding wires. external connecting wires. Since the clamping cartridge with its clamping body against the clamping screw is inserted tightly into the clamping housing, no liquid impregnating agent from the inside of the clamping housing against the clamping screw can penetrate into the clamping state. Finally, it allows a clamping housing that can be easily attached to the lower part and contains a clamping insert, optimally adapted to the respective space conditions of the choke or transformer, so that the coupling device is suitable especially for compact, fully integrated connection technique to achieve construction forms of particularly short construction lengths .
Režasta odprtina, ki je omejena od nožastih kontaktov spenjalnega vložka, ima lahko z ustrezno odmero spenjalnih krakov s prednostjo dolžino, ki presega premer več priključnih žic, ki se jih sprejme, in s tem prav tako prevzame nalogo ustvarjanja stikalnih povezav, med tem ko je lahko masivno spenjalno telo izoblikovano z najmanj dvema priključnima izvrtinama, ki se križata, da bi omogočilo priključitev po izbiri zunanjih priključnih žic z dveh različnih smeri.The slit opening, which is limited by the blade contacts of the coupling insert, may, with an appropriate dimension of the coupling arms, preferably have a length exceeding the diameter of the multiple connecting wires to be received, and thereby also assume the task of creating switching connections while a solid coupling body may be formed with at least two connecting holes that intersect to allow connection, by choice, of external connecting wires from two different directions.
Razen tega se lahko v prednostni izvedbeni obliki izvede takšna razporeditev, da je talno področje spenjalnega telesa, ki nosi spenjalne krake, izoblikovano v glavnem togo in so druga področja sten, ki omejujejo priključno izvrtino (izvrtine) izoblikovana tako, da se lahko elastično preoblikujejo pri čemer je zategnjen spenjalni vijak ob vzdolžnem preoblikovan ju priključne izvrtine (izvrtin) in v področju dna, ki se v glavnem ne more preoblikovati, doveden s področij stene, ki se lahko elastično preoblikujejo, kot prednapetost. Ta prednapetost izravnava po eni strani v danih okoliščinah nastopajoče zmanjševanje trdno vpetega priključnega vodnika; po drugi strani pa se s togim izoblikovanjem področja dna odpravi možnost nezaželenega razkrečenja spenjalnih krakov pri zategovanju spenjalnega vijaka.Moreover, in a preferred embodiment, the arrangement may be arranged such that the floor area of the clamping body carrying the clamping arms is substantially rigid and that the other wall regions limiting the connecting hole (s) are shaped so that they can be resiliently reshaped at the tightening of the clamping screw along the longitudinally reshaped connecting holes (holes) and in the region of the non-substantially removable bottom being brought in from the elastically resilient wall regions as prestressing. This bias offsets, on the one hand, under the circumstances, the diminishing effect of the tightening of the connection cable; on the other hand, rigidly forming the bottom area eliminates the possibility of unwanted opening of the clamping arms when tightening the clamping screw.
Preproste razmere pri izdelavi nastopajo, če obsega spenjalno ohišje najmanj eno komoro, v katero je spenjalno telo vakuumsko tesno prilagojeno. Načeloma pa so predstavljive tudi izvedbene oblike, pri katerih je spenjalno telo zlepljeno ali zalito z obdajajočimi deli stene spenjalnega ohišja ali pa je neposredno pri izdelavi vbrizgano ali voblikovano v spenjalno ohišje, ki sestoji iz umetne snovi.Simple fabrication conditions occur when the clamping housing comprises at least one chamber into which the clamping body is vacuum-tightly adapted. In principle, embodiments are also provided in which the clamping body is glued or sealed with surrounding portions of the wall of the clamping housing or is injected or molded directly into the construction into a clamping body consisting of plastic.
Da bi se preprečilo, da se pri impregniranju dušilke s popolnoma montirano priključno spenjalno napravo zatakne izolacijski material, ki je prišel od zunajzv spenjalne vijake, je smotrno, da ima spenjalno ohišje prioblikovano prekrivalo, ki sprejme spenjalni vijak in ki se lahko po vstavitvi spenjalnega vložka in potem po impregniranju odpre. Iz podobnih razlogov so lahko izrezi spenjalnega ohišja, ki vodijo k priključni izvrtini oz. priključnim izvrtinam in ki so namenjeni za priključne žice, pri vstaviti spenjalnega vložka zaprti in se odprejo šele po impregniranju.In order to prevent the insulation material that came from the outside with the clamping screws in impregnating the choke with a fully mounted coupler, it is advisable that the clamping housing has a shaped cover that accommodates the clamping screw and which can be inserted after insertion of the coupling insert and then opens after impregnation. For similar reasons, the cutouts of the coupling housing which lead to the connection hole or. The connecting holes, which are intended for connecting wires, are closed when inserting the coupling insert and only open after impregnation.
Posebno zanesljivo uvajanje priključnih žic med nožaste kontakte in stabilno, položajno določeno ležajenje uvedenih priključnih žic omogoča prednostna izvedbena oblika, pri kateri obsega spodnji del vsaj eno nalego za priključne žice, ki štrli pri nameščenem spenjalnem ohišju med spenjalne krake. Ta nalega je izoblikovana smotrno v odvisnosti od izoblikovanja spenjalnih krakov. Če so, kot je to smotrno, spenjalni kraki delno valjasti in je z njimi obdana podolgovata izvotlina v obliki kanala, v katero vstopa vsaj ena režasta odprtina in je ta v danih okoliščinah valjasta, je lahko nalega izoblikovana po načinu čepa, ki štrli v izvotlino v obliki kanala in ki je prioblikovan na spodnjem delu.Particularly reliable insertion of the connecting wires between the blade contacts and the stable, positionally positioned bearing of the introduced connecting wires is provided by a preferred embodiment in which the lower part comprises at least one contact for the connecting wires projecting into the clamping housing between the clamping arms. This fitting is designed in accordance with the design of the coupling arms. If, as appropriate, the coupling arms are partially cylindrical and are surrounded by an elongated bore in the form of a duct into which at least one slit opening enters and is cylindrical in the circumstances, it may be formed by the method of a plug projecting into the recess. in the form of a channel and which is molded at the bottom.
Spenjalno ohišje in spodnji del lahko obsegajo v ostalem s prednjim delom zaskočna sredstva, s pomočjo katerih se lahko medsebojno zaskočijo, tako da je podana posebno preprosta možnost montaže.The clamping housing and the lower part may comprise, inter alia, with the front part, locking means by which they can be interlocked so that a particularly simple mounting option is provided.
Ker se z namestitvijo spenjalnega ohišja na spodnji del s priključnih žic, ki ležijo med spenjalnimi kraki spenjalnega vložka, avtomatično sname izolacijo in ustvari kontakt, obstaja posebno takrat, če se priključna spenjalna naprava zatem impregnira skupno s pripravo, tako da se ne more več odpreti, želja, da se pred impregnacijo preizkusi, če obstaja med priklju čnimi žicami in spenjalnim vložkom brezhibna električna povezava V ta namen lahko obsegata spenjalno ohišje in/ spodnji del izreze, skozi katere se lahko dovede spenjalni vložek pri spenjalnem ohišju, ki je spojeno s spodnjim delom, od zunaj s kontaktnim kosom.Because by mounting the clamping housing to the bottom of the connecting wires that lie between the clamping arms of the clamping cartridge, it automatically removes the insulation and creates contact, especially if the coupler is then impregnated with the device so that it can no longer be opened , wish to be tested before impregnation if there is a faultless electrical connection between the connecting wires and the clamping insert. For this purpose, they may comprise a clamping housing and / or a lower portion of the recess through which a clamping insert can be provided at the clamping housing connected to the lower one. in part, from the outside with the contact piece.
Pri posebno smotrni izvedbeni obliki sta spenjalno ohišje in/ali spodnji del dela izolacije navitja ali tuljavnika dušilke ali transformatorja. Pri tem je podana tudi glede na dolžino gradnje posebno ugodna konstrukcija, če sta spenjalno ohišje ali spodnji del izoblikovana kot ohišje v obliki kape za najmanj delno prekritje glave navitja dušilke ali transformato rja, ki obsega pritrdilno napravo in v danih pogojih preoblikovan jezik, ki se lahko potisne v vmesni prostor med glavo navitja in paket pločevine dušilke ali transformatorja. V tem primeru se lahko s prednostjo ohišje v obliki kape, ki tvori spodnji del, na tisti strani, ki je obrnjena proti prostemu koncu jezika, zapre z nanj nameščenim spenjalnim ohišjem, tako da sploh ne nastopi nobena povečava dolžine gradnje celotne priprave. Razen tega lahko obsega spenjalno ohišje sprejemni prostor, v katerem se končujejo odprtine za priključne žice in ki se lahko v danih pogojih zapre z nanj poveznjenim pokrovom ter je namenjen električnemu stikalnemu elementu, npr. varovalnemu elementu ali nadzorni pripravi za prekoračitev temperature. Zelo stisnjen način gradnje je podan, če je sprejemni prostor med spenjalnimi vložki razporejen ležeče na ozki strani spenjalnega ohišja.In a particularly advantageous embodiment, the coupling housing and / or the lower part of the insulation of the winding or coil of the choke or transformer. In addition, a particularly advantageous construction is provided with regard to the length of the construction, provided that the coupling housing or the lower part is formed as a housing in the form of a cap for at least partially covering the winding head of a damper or transformer, comprising a fixture and, under the conditions, a transformed tongue which it can slide into the gap between the winding head and the package of the choke or transformer sheet. In this case, the lower case-shaped cap housing, on the side facing the free end of the tongue, may advantageously be closed by a clamping housing mounted thereon, so that no increase in the length of construction of the entire device can occur at all. In addition, the coupling housing may comprise a receiving space in which the openings for the connecting wires terminate and which can be closed in a given condition by a cover connected thereto and intended for an electrical switch element, e.g. a safety element or control device for exceeding the temperature. A very compressed construction method is provided if the receiving space between the coupling inserts is arranged lying on the narrow side of the coupling housing.

V sl. 1,2 prikazana dušilka, ki je izoblikovana tudi kot transformator, je namenjena posebno za uporabo kot predpriključna priprava za plinske sijalke. Obsega sorazmeroma kratek paket 1 pločevine v obliki bloka v U-/T- ali E-/I-rezu, katerega U-kraka sta povezana s sponko 2. Prek paketa 1 pločevine stransko izstopajoče in ne nadalje prikazane glave navitja so na obeh straneh paketa 1 pločevine prekrite vsakokrat z ohišjem v obliki kape, ki sestoji iz izolacijskega materiala in ki ima v bistvu obliko prereza U-oblike ter nosi na strani roba na treh straneh obdajajočo ravno prioblikovano robno prirobnico 4, s katero nalega na paketu 1 pločevine. Na odprti zadnji strani ohišja je prioblikovan jezik 5 (sl. 3) ki leži v ravnini robne prirobnice 4 in ki je potisnjen v vmesni prostor med glavo navitja in paket 1 pločevine in s tem fiksira ohišje 3 na paketu 1 pločevine. Jezik 5 tvori s tem pritrdilno napravo za ohišje 3 in istočasno izolacijo glave navitja proti paketu 1 pločevine.In FIG. The figure 1.2, also designed as a transformer, is intended specifically for use as a pre-attachment for gas lamps. It consists of a relatively short package 1 of sheet metal in the form of a U- / T- or E- / I-cut, the U-arms of which are connected to the clamp 2. Through the package 1 of the sheet, the laterally protruding and not further shown winding heads are on both sides of the package. 1 of the sheet is each covered by a cap-shaped housing consisting of an insulating material, which is essentially U-shaped cross-section and bears, on the edges on three sides, a circumferentially shaped flange 4, adjacent to the package 1 of the sheet. On the open back of the housing is formed a tongue 5 (Fig. 3) which lies in the plane of the flange edge 4 and which is pushed into the space between the winding head and the plate 1 of the sheet, thereby fixing the housing 3 on the plate 1 of the sheet. The tongue 5 thus forms a mounting device for the housing 3 and at the same time insulates the winding head against the package 1 of the sheet.
V opisano, izolacijo glave navitja, ki tvori del izolacije navitja, je vsakokrat integrirana električna priključna spenjalna naprava 6, ki omogoča, da se vzpostavi električna povezava med žicami navitja in zunanjimi priključnimi žicami.As described above, the winding head insulation forming part of the winding insulation is in each case integrated with an electrical terminal coupler 6, which allows the electrical connection between the winding wires and the external connecting wires to be established.
Ta priključna spenjalna naprava 6 obsega v glavnem pravokotno, škatlasto spenjalno ohišje 7, ki je izoblikovano iz izolacijskega materiala (materiala iz umetne snovi) ter sestoji iz ravne prednje stene 8, dveh ozkih stranskih sten 9 in zgornje krovne stene 10. Proti zadnji strani odprto spenjalno ohišje 7 (sl. 7, 8) vsebuje nad krovno steno 10 ležeč, od podaljšane prednje stene 8 in delov 11 stranske stene ter od zadnje stene omejen koritast sprejemni prostor 13 za ne nadalje prikazan električni sestavni del npr. varovalni element, katerega dovodi se lahko uvedejo v sprejemni prostor 13 skozi na robu odprte režaste izreze 14, 15 (sl. 3)· Za zapiranje sprejemnega prostora 13 je uporabljen pokrov 16, ki se lahko s pomočjo prioblikovanih zaskočnih prstov 17 z zaskočnimi izrezi 18 zaskoči na notranji strani delov 11 stranske stene.This coupling device 6 comprises a substantially rectangular, box-like coupling housing 7, which is formed of an insulating material (plastic material) and consists of a flat front wall 8, two narrow side walls 9 and an upper deck wall 10. Towards the rear open the clamping housing 7 (Figs. 7, 8) contains above the roof wall 10, a troughed receiving space 13 restrained from an elongated front wall 8 and portions 11 of the lateral wall, for a non-further shown electrical component e.g. a securing element whose inlets can be introduced into the receiving space 13 through the edge of the open slotted recess 14, 15 (Fig. 3) · To close the receiving space 13, a cover 16 is used which can be formed by snapping fingers 17 with snapping slots 18 snaps on the inside of the 11 sidewall portions.
V obeh vogalih med prednjo steno 8 in stranskimi stenami 9 sta izoblikovani v notranjosti spenjalnega ohišja 7 dve s preoblikovanimi deli 19 stene omejeni, v preseku v glavnem pravokotni komori 20, ki prehajata prek valjaste odprtine 21 v krovni steni 10 v vsakokrat po eno na zunanji strani krovne stene prioblikovano prekrivno kapo 22 v obliki prisekanega stožca. Kot se posebno vidi iz sl. 3, ležita obe prekrivni kapi 22, prav tako kot komori 20 stransko poleg sprejemnega prostora 13 blizu stranskih sten 9 spenjalnega ohišja 7, pni čemer tvori izstopajoča krovna stena 10 neke vrste konzolo.In the two corners between the front wall 8 and the side walls 9, two boundary shaped sections 19 are formed inside the clamping housing 7, with a cross-section in the main rectangular chamber 20 passing through one cylindrical opening 21 in the roof wall 10 each at the outer sides of the deck wall shaped overlay cap 22 in the form of a truncated cone. As can be seen from FIG. 3, both overlaps 22 are located, just like the chambers 20 laterally adjacent to the receiving space 13 near the side walls 9 of the clamping housing 7, forming a protruding roof wall 10 of a kind of console.
V vsako od obeh komor 20 je vstavljen vakuumsko tesno z notranje strani spenjalnega ohišja 7 npr. iz medenine obstoječ spenjalni vložek 23- Gradnja spenjalnih vložkov 23 je razvidna posebno iz sl. 3 in 9Vsak spenjalni vložek 23 obsega masivno, v preseku v glavnem pravokotno in v obliki notranjega obrisa komore 20 prilagojeno spenjalno telo 24, v katerem sta izoblikovani dve križajoči se priključni izvrtini 25 za ne nadalje prikazane zunje priključne vodnike. V obe priključni izvrtini 25 se izteka v področju njihovega mesta križanja navojna izvrtina 26, v ka14 tero je uvit spenjalni vijak 27. Na spenjalnem vijaku 27 nasproti ležeči talni strani 28 spenjalnega telesa 24 kot takega po načinu vijačne sponke izoblikovanega spenjalnega vložka 23 sta prioblikovana dva v medsebojnem razmiku potekajoče nameščena spenjalna kraka 30, ki sta izoblikovana s spenjalnim telesom 24z povezanim z votlo valjastim čepom z dvema v njegovem plašču nameščenima, medsebojno nasproti ležečima režastima, na robu odprtima odprtinama 32, ki se iztekata v valjasto, koaksialno izvrtino, ki tvori izvotlino 33 v obliki kanala. Oba spenjalna kraka 33 imata tako obliko v glavnem valjastih polskodel; na njihovih robovih, ki omejujejo obe režasti odprtini 32, nosita nožaste kontakte 34, ki so na način, razviden iz sl. 9, vsaj prek dela vzdolžnega poteka režastih odprtin 32 oblikovani nekoliko klinasto iztekajoče. Širina vsake od režastih odprtin 32 je nekoliko manjša kot premer pri 35 nakazane, vmes vstavljene priključne žice. Pri natiskanju spenjalnega vložka 23 na priključno žico 35 se zato njena izolacija z nožastimi kontakti 34 samodejno razreže, tako da nastane med prevodnikom, ki tvori priključni del 35 in je stisnjen med spenjalne krake 30, in spenjalnimi kraki 30 in s tem spenjalnim vložkom 23 brezhiben kontakt.A vacuum seal is inserted into each of the two chambers 20 from the inside of the clamping housing 7 e.g. brass existing coupling insert 23- The construction of coupling inserts 23 can be seen in particular from FIG. 3 and 9Each clamping insert 23 comprises a massive, cross-sectional view, mainly rectangular and in the shape of the inner contour of the chamber 20, is adapted to the clamping body 24, in which two intersecting connecting holes 25 are formed for the outer connection conductors not further shown. In both connecting holes 25, a threaded hole 26 extends in the area of their intersection point, in which a clamping screw 27 is screwed in. A two screws are formed on the clamping screw 27 opposite the ground floor 28 of the clamping body 24 as such. spaced apart joints 30, formed by a clamping body 24 , connected to a hollow cylindrical plug with two slits arranged opposite each other, openings 32 extending into the cylindrical, coaxial bore forms a conduit 33 in the form of a duct. Both coupling arms 33 thus have a substantially cylindrical shape; at their edges bounding the two slit openings 32, they carry knife contacts 34, which can be seen in FIG. 9, at least through a portion of the longitudinal course of the slit openings 32, formed somewhat wedge-shaped. The width of each of the slit openings 32 is slightly smaller than the diameter of 35 pointed, interconnected connecting wires. When printing the coupling insert 23 onto the connecting wire 35, its insulation with knife contacts 34 is therefore automatically cut so that it is formed between the conductor forming the connecting part 35 and squeezed between the coupling arms 30 and the coupling arms 30 and thereby the coupling insert 23 is seamless contact.
Dolžina spenjalnih krakov 30 se lahko izbere tako, da se lahko v nasprotju k prikazu na sl. 9 na opisan način istočasno sname izolacija in oblikuje kontakt tudi z več, posebno dvema ali tremi priključnimi žicami 35, ki ležijo druga prek druge.The length of the coupling arms 30 may be chosen such that, contrary to the illustration in FIG. 9 in the same manner removes the insulation at the same time and forms contact with several, especially two or three connecting wires 35 which lie over each other.
Spenjalno telo 24 je izoblikovano s svojimi priključnimi izvrtinami 25 in te obdajočimi deli stene tako, da deluje talno področje 36, hi nosi oba spenjalna kraka 30 in ki leži približno pod črtkano črto 37 (sl. 9) po načinu v glavnem toge plošče. V nasprotju s tem so približno stransko k črtkanim črtam 38 ležeča stranska področja 39 stene odmerjena tako, da so pri zategovanju spenjalnega vijaka 27 elastično podajna tako, da prevzame priključna izvrtina 25 pri zategnjenem spenjalnem vijaku 27 pri 40 pretirano prikazano ovalno obliko preseka.The clamping body 24 is formed by its connecting holes 25 and these surrounding portions of the wall so that the floor area 36 operates, hi the two clamping arms 30 and which lies approximately below the dashed line 37 (Fig. 9) in the manner of a substantially rigid plate. In contrast, the lateral lateral regions 39 of the walls, which are approximately lateral to the dashed lines 38, are dimensioned so as to be elastically adjustable when tightening the clamping screw 27 so as to assume an over-oval cross-sectional shape of the clamping screw 27 at 40.
S tem izoblikovanjem spenjalnega telesa 24 se doseže, da je spenjalni vijak 27 v zategnjenem stanju pod prednapetostjo in da s tem samodejno kompenzira eventualno zmanjševanje debeline v priključni izvrtini 25 ležeče priključne žice. Istočasno pa preprečuje v glavnem toga izvedba talnega področja 36, da bi se oba spenjalna kraka 30 pri zategovanju spenjalnega vijaka 27 razkrečila in s tem zrahljala kontakt z vrinjeno priključno žico 35.This design of the clamping body 24 results in the clamping screw 27 being prestressed under tension and thus automatically compensates for any reduction in thickness in the connecting hole 25 of the connecting wire. At the same time, it prevents, in the main, the rigid implementation of the floor area 36 from breaking both coupling arms 30 while tightening the coupling screw 27, thereby loosening contact with the interrupted connection wire 35.
Opisan spenjalni vložek 23 je vtisnjen s svojim spenjalnim telesom 24 vakuumsko tesno v ustrezno komoro 20 spenjalnega ohišja 7, pri čemer štrli spenjalni vijak 27 v votlino prekrivne kape 22, kot je to razvidno posebno iz sl. 8.The described clamping insert 23 is pressurized with its clamping body 24 in a vacuum tight manner into the corresponding chamber 20 of the clamping housing 7, with the clamping screw 27 projecting into the cavity of the overlay cap 22, as can be seen in particular from FIG. 8.
Na ohišje 3, ki je v preseku v glavnem U-oblike in ki prekriva glavo navitja na že opisan način in ki je zaprto spodaj z dnom 400 (sl. 5), je prioblikovano zgoraj v preseku v glavnem pravokotno, z ravnimi boki omejeno delno ohišje 41, ki je omejeno z ravnimi ploskvami in obsega prednjo steno 42 ter dve stranski steni 43- Izmere delnega ohišja 43 so izbrane tako, da se lahko natisne spenjalno ohišje 7 na delno ohišje 41, ki tvori spodnji del, od zgoraj, t.j. s strani, ki tvori prosti konec je16 zika 5, tako da ohišje 3 na tej strani zapre. V področju stranskih sten 43 so prioblikovani na delnem ohišju 41 zaskočni nosovi, ki vprijemajo pri nataknjenem spenjalnem ohišju 7 v ustrezne zaskočne izvotline 45 (sl. 3) spenjalnega ohišja 7 in medsebojno zaskočijo obe ohišji 41, 7.The housing 3, which is in cross section mainly U-shaped and which covers the winding head in the manner described above and which is closed below with the bottom 400 (Fig. 5), is shaped above in cross-section mainly rectangular, with straight flanks bounded partially a housing 41 bounded by flat surfaces comprising a front wall 42 and two side walls 43- The dimensions of the partial housing 43 are selected so that the coupling housing 7 can be printed onto the partial housing 41 forming the lower part, i.e. from the side forming the free end is 16 pin 5, so that the housing 3 on this side closes. In the region of the side walls 43, snap noses are formed on the partial housing 41, which engage the corresponding locking bores 45 (FIG. 3) of the clamping housing 7 with the clamped clamping housing 7 and snap the two housing 41, 7 together.
Razen tega je v vsaki od stranskih sten 43, ki imajo ustrezno debelino stene, predviden prioblikovan navpičen, valjast čep 46 (sl. 5, 9), katerega premer ustreza z zračnostjo premeru valjaste izvotline 33 spenjalnega vložka 23 in ki je obdan z izrezom 47 v obliki obročastega kanala, ki je namenjen sprejemu obeh delno valjastih spenjalnih krakov 30 spenjalnega vložka 23· čep 46 tvori sprejem za priključno žico 35. V ta namen je opremljen s prečno potekajočim utorom 48, na katerega se priključujeta obe žlebasti poglobitvi 49 (sl. 5) v vsakokratni stranski steni 43, ki sta namenjeni sprejemu priključne žice 35.In addition, a vertical, cylindrical plug 46 (FIGS. 5, 9) is provided in each of the side walls 43 having an appropriate wall thickness, the diameter of which corresponds to the clearance of the diameter of the cylindrical bore 33 of the coupling insert 23 and which is surrounded by a notch 47 in the form of a annular groove intended to receive both partially cylindrical clamping arms 30 of the clamping insert 23 · the plug 46 forms a receptacle for the connecting wire 35. To this end, it is provided with a transverse groove 48 to which both grooves 49 are connected (FIG. 5) in each side wall 43, which are intended to receive the connecting wire 35.
Pri montaži opisane priključne spenjaine naprave 6 se najprej natisne na glavo navitja kapi podobno ohišje 3 s svojim jezikom 5, katero pokriva glavo navitja. Zatem se vložijo od tuljave prihajajoče priključne žice 35 navitja prek izrezov 45 ohišja 3 (sl. 6) v žlebaste poglobitve 49 in utor 48 čepa 46, ki tvori nalego za priključne žice.When mounting the described connection clamp of the device 6, a similar housing 3 with its tongue 5, which covers the winding head, is first printed on the winding head. Subsequently, they are inserted from the coil of the incoming connecting wire 35 through the grooves 45 of the housing 3 (Fig. 6) into the grooves 49 and the groove 48 of the plug 46, which forms a contact for the connecting wires.
Zatem se na opisan način s spenjalnimi vložki 23 opremljeno spenjalno ohišje 7 natisne od zgoraj na delno ohišje 41, dokler ne zaskočijo zaskočni nosovi 44 v zaskočne izreze 45 in s tem zaskočno spojijo spenjalno ohišje 7- Pri tem natisnem gibanju sežeta oba spenjalna kraka 30 viličasto prek v utoru 48 stransko vodene in navzdol oprte priključne žice 35, pri če17 mer razrežejo nožasti kontakti 34 izolacijo z lakom in vdrejo tako globoko v material žice, da je zagotovljeno zanesljivo kontaktiranje.Thereafter, the clamping sleeve 7 provided with the clamping inserts 23 is printed from above to the partial housing 41 until the locking nozzles 44 snap into the recessed recesses 45, thereby snapping the clamping housing 7- In this printing motion, the two clamping arms 30 are forked. through the groove 48 of the laterally guided and downwardly connected connecting wire 35, cut the insulated contacts 34 with the insulation with lacquer, and penetrate so deep into the wire material so that reliable contact is ensured.
Da bi se preizkusilo to kontaktiranje pred temu sledečim impregniranjem, je na delnem ohišju 41, ki tvori spodnji del, v področju obeh stranskih sten 43 predviden po en izrez 50, ki dopušča v sodelovanju s pripadajočim izrezom 51 v področju stranskih sten 9 in prednjo steno spenjalnega ohišja 7 v sestavljenem stanju dotik spenjalnega telesa 24 vsakokratnega spenjalnega vložka 23 z električno preizkusno konico.In order to test this contacting before this subsequent impregnation, a cutout 50 is provided on the partial housing 41 forming the lower part 43 in the area of the two sidewalls 43, which allows, in conjunction with the corresponding cutout 51, in the area of the sidewalls 9 and the front wall of the clamping housing 7 in the assembled state contact of the clamping body 24 of the respective clamping insert 23 with the electrical test tip.
Če je kontaktiranje po preizkusu brez napak, se naprava, ki je na ta način s priključno spenjalno napravo 6, ki je integrirana v izolacijo navitja, združena v kompaktno gradbeno enoto, impregnira v celoti. Ker so spenjalni vložki 23 s svojimi spenjalnimi telesi vtisnjeni v komore 20 vakuumsko tesno in ležijo spenjalni vijaki 23 v prekrivnih kapah 22, in pri tem impregnacijskem poteku impregnacijsko sredstvo ne more vplivati na spenjalne vložke 23. Po strditvi impregnacijskega sredstva se prekrivne kape 22 zgoraj odrežejo, s čemer postanejo spenjalni vijaki 27, ki so ostali prek svoje dolžine električno izolirani, od zunaj dostopni. Istočasno se vnesejo v stranske stene 9 in prednje, stene 8 spenjalnega ohišja s priključnimi izvrtinami 25 spenjalnih vložkom 23 ujemajoči se izrezi v obliki izvrtin 53 (sl. 1).If the contact after the test is faultless, the device thus incorporated into the compact construction unit is impregnated completely with the coupling device 6 integrated in the winding insulation. Because the clamping inserts 23 are pressurized into the chambers 20 in a vacuum-tight manner with the clamping bodies 23 and the clamping screws 23 are located in the cover caps 22, and in this impregnation course the impregnating agent cannot affect the clamping inserts 23. After curing the impregnating agent, the cover caps 22 are cut off above , thereby making the electrically insulated clamping bolts 27 that are electrically insulated beyond their length accessible. At the same time, matching recesses in the form of holes 53 (Fig. 1) are inserted into the side walls 9 and the front, walls 8 of the coupling housing with the connecting holes 25 of the coupling insert 23.
V danih pogojih se lahko sedaj v sprejemni prostor 13 vloži eden ali več električnih sestavnih elementov, npr. bimetalnih ali varovalnih elementov, ki se električno povežejo s priključnimi žicami, ki so bile uvedene skozi izreze 14, 15 ali izreze 54 (sl. 7). Po namestitvi pokrova 16 je priprava pripravljena za obratovanje. Na pokrovu 16 znotraj prioblikovan nastavek 55 v obliki kadi (sl. 3) se lahko istočasno uporablja za to, da fiksira električni sestavni del v sprejemnem prostoru 13 položajno čvrsto.Under the given conditions, one or more electrical components can now be inserted into the receiving compartment 13, e.g. bimetallic or safety elements that electrically connect to the connecting wires introduced through slots 14, 15 or slots 54 (Fig. 7). After the cover 16 is installed, the unit is ready for operation. The lid 16 inside a tub-shaped nozzle 55 (Fig. 3) can at the same time be used to fix the electrical component in the receiving space 13 positionally tight.
Če se uporabljajo električni sestavni elementi, na katere impregnacijski potek ne more vplivati, se lahko montirajo ti že pred impregniranjem. Predstavljivo je tudi, da se v posamičnih primerih pokrov 16 izpusti.If electrical components are used that are not affected by the impregnation path, they may be mounted before impregnation. It is also conceivable that in individual cases the lid 16 is omitted.
V predhodnem je bil izum opisan v zvezi s posebno izolacijo glave navitja z ohišjem 3 dušilke ali transformatorja. Načeloma bi bilo tudi predstavljivo, da se uporabi priključno spenjalno napravo v zvezi z drugimi pripravami, npr. tako, da je delno ohišje 41 prioblikovano na prirobnici tuljavnika majhnega transformatorja itd. Končno bi bilo tudi predstavljivo, da se priključna spenjalna naprava, ki sestoji iz spenjalnega ohišja 7, opremljenega s spenjalnimi vložki, in delnega ohišja 41, ki tvori spodnji del, uporabi kot samostojna spenjalna naprava. V tem primeru bi bilo delno ohišje 41 v danih okoliščinah zaprto z ravno talno steno in zadnjo steno, pri čemer je potrebno v stenah spenjalnega ohišja 7 in delnega ohišja 41 predvideti ustrezne izreze za uvajanje priključne žice.The invention has previously been described in connection with the special isolation of the winding head with the housing of a 3 choke or transformer. In principle, it would also be conceivable to use a coupler in connection with other devices, e.g. so that the partial housing 41 is formed on the flange of the small transformer coil, etc. Finally, it would also be conceivable to use a coupling device consisting of a clamping housing 7 equipped with clamping inserts and a partial housing 41 forming the lower part as a stand-alone coupling device. In this case, the partial housing 41 would, in the circumstances, be enclosed with a flat floor wall and a rear wall, and appropriate cutouts for introducing the connecting wire should be provided in the walls of the coupling housing 7 and the partial housing 41.
