Description

Den foreliggende oppfinnelse vedrorer et endestykke for spole-stairaner av det slag som er angitt i patentkravets ingress. The present invention relates to an end piece for coil stair rails of the type specified in the preamble of the patent claim.

Innenfor telefonteknikken anvendes det en rekke elektromekaniske komponenter, som har det felles, at en magnetspole med jernkjerne har den nodvendige trekk-kraften . Derfor er spolen som konstruk-sjon av meget stor betydning. Utformingen av jernkjernen, dens fastsetting i komponenten, som kan utgjbres av et relé, en velger etc., samt konstruksjonen av spolestammen - enten den utgjores av en los spole eller består av ende-stykker som er fastsatt på kjer-nen - er av meget gammel dato. Spoleviklingsmaskinene er med årene blitt forbedret og gjort hurtigere, men noen epokegjørende for-andringer av spolestammen har neppe skjedd. Denne situasjon gjor at de forbedringer som kan gjores for å lette spoletilvirkningen og minske feilkilden, har vidt inngående betydning for komponen-tens funksjon og dkonomi. Spolen er ofte en dominerende part, når det gjelder tilvirkningskostnadene for den elektromekaniske komponent. Within telephone technology, a number of electromechanical components are used, which have in common that a magnetic coil with an iron core has the necessary pulling force. Therefore, the coil as a construction is very important. The design of the iron core, its fixing in the component, which can be produced by a relay, a selector etc., as well as the construction of the coil stem - whether it is made up of a loose coil or consists of end pieces which are fixed on the core - are of great importance old date. Over the years, the coil winding machines have been improved and made faster, but any epoch-making changes to the coil stem are unlikely to have occurred. This situation means that the improvements that can be made to facilitate coil production and reduce the source of error have far-reaching implications for the component's function and economy. The coil is often a dominant party when it comes to the manufacturing costs of the electromechanical component.

Ved spolestammer av. det slag som oppfinnelsen vedrorer,er det ene ende-stykket L-formet. Endestykkets ene ben er forsynt med et gjennomgående hull for spolekjernen og i dens andre ben er parallelle renner anordnet for anordning av loddefliker. Fra disse renner går tilledningstråder til den eller de viklinger som den ferdige spolen er forsynt med. Hvis man ser bort fra tillednings-tråden til det ytterste viklingssjiktet, vil hver tilledningstråd bli krysset av de nærmest endestykket beliggende viklingslag i hvert viklingssjikt. Mellom tilledningstrådene og de Inntillig-gende viklingslag kan det, når spolen er i drift, oppstå betydelige potensial - forskjeller på grunn av selvinduksjon i spolen, med overslag, odelagt isolasjon og kortslutning som folge. For å unngå kortslutning har man ved vikling av spolen dekket over tilledningstrådene med 'isolerende klisterlapper og dermed hindret disse fra å komme i kontakt med nærliggende<*>viklingslag. Under viklingsoperasjonen skjer det imidlertid lett at en klisterlapp losner og folger med innimellom viklingslagene. Når en spole er-ferdig viklet, er det ikke alltid mulig å se om klisterlappene sitter på plass eller har gått inn i viklingen. In case of coil strains off. the type to which the invention relates, one end piece is L-shaped. One leg of the end piece is provided with a through hole for the coil core and in its other leg, parallel channels are arranged for the arrangement of solder tabs. From these channels lead wires go to the winding(s) with which the finished coil is provided. If one ignores the lead wire to the outermost winding layer, each lead wire will be crossed by the winding layers located closest to the end piece in each winding layer. Between the supply wires and the adjacent winding layers, when the coil is in operation, significant potential differences can arise due to self-induction in the coil, with flashover, broken insulation and short circuit as a result. To avoid a short circuit, when winding the coil, the supply wires have been covered with insulating adhesive patches and thus prevented these from coming into contact with nearby<*>winding layers. During the winding operation, however, it is easy for an adhesive patch to come loose and follow between the winding layers. When a coil is finished winding, it is not always possible to see whether the adhesive patches are in place or have entered the winding.

For å komme ifra dette usikerhetsmoment har man mer og mer gått over til å legge tilledningstrådene i spor anordnet i stamme-endestykkét. Under selve viklingsoperasjonen holdes hver tilledningstråd strukket mellom loddeflik og vikling og folger da sporets bunn, men for at tilledningstrådene skal tåle selve transporten - av den ferdige spolen som de bevegelser som ved drift oppstår innenfor spolen på grunn av temperaturvariasjoner, er det hensikts-messig å slakke tilledningstrådene. Når. en tilledningstråd er blitt slakket, kommer den imidlertid lett i beroring med nærliggende viklingslag og overslagsrisikoen er storre for denne type av spoler enn for slike hvor tilledningstrådene er blitt isolert med klisterlapper. In order to avoid this point of uncertainty, more and more people have switched to laying the supply wires in grooves arranged in the stem end piece. During the actual winding operation, each lead wire is kept stretched between the solder tab and the winding and then follows the bottom of the track, but in order for the lead wires to withstand the transport itself - of the finished coil as well as the movements that occur within the coil during operation due to temperature variations, it is appropriate to slacken the supply wires. When. a lead wire has been slackened, however, it easily comes into contact with nearby winding layers and the risk of overturning is greater for this type of coils than for those where the lead wires have been insulated with adhesive patches.

Formålet med den foreliggende oppfinnelsen er å eliminere oven-for nevnte ulemper og dette oppnås ved at spolestammeendestykket har fått de i patentkravene angitt kjennetegn. The purpose of the present invention is to eliminate the above-mentioned disadvantages and this is achieved by the coil stem end piece having the characteristics specified in the patent claims.

Et utforelseseksempel av oppfinnelsen skal nærmere forklares under henvisning til valgte tegning, på hvilken fig. 1 viser et forste ben av et spolestammeendestykke i planriss, fig. 2 viser et endestykke i sideriss og delvis i snitt sammen med en del av tilhorende spolekjerne og vikling og fig. 3 viser et andre ben av samme endestykke og en del av tilhorende vikling. An embodiment of the invention will be explained in more detail with reference to the selected drawing, in which fig. 1 shows a first leg of a coil stem end piece in plan view, fig. 2 shows an end piece in side view and partly in section together with part of the associated coil core and winding and fig. 3 shows a second leg of the same end piece and part of the associated winding.

1 fig. 1, som viser et forste ben av et spolestammeendestykke i 1 fig. 1, showing a first leg of a coil stem end piece i

planriss, er 1 den felles betegnelsen for i"endéstykkét anordnede spor for tilledningstråder til den ferdige spolens viklinger. Sporene som er blitt utformet med tanke på at tilledningstrådene ved varierende kjernediametre og viklingshoyder uten tverrgående boyninger lett kan gli ned i sporene og der beskyttes mot nærliggende viklingslag, munner ut i renner 2. I disse renner er loddefliker anordnet, her representert av flikene 3 dg 4, hvilke for å lette loddingsarbeidet i forbindelse med viklingen er oppboyde fra sine respektive renner. Fig. 2 viser et spolestammeendestykke i sideriss og delvis i snitt, idet skjæringslinjen folger det spor som utmunner i rennen med loddeflik 3. I fig. plan view, 1 is the common term for grooves arranged in the end piece for supply wires to the windings of the finished coil. The grooves have been designed with the view that the supply wires with varying core diameters and winding heights without transverse bends can easily slide down into the grooves and are protected from nearby winding layer, opening into channels 2. In these channels, solder tabs are arranged, here represented by tabs 3 d 4, which to facilitate the soldering work in connection with the winding are bent up from their respective channels. Fig. 2 shows a coil stem end piece in side view and partly in section, as the cutting line follows the groove that opens into the groove with solder tab 3. In fig.

2 vises også endepartiet av en kjerne 4 med tilhorende vikling 5, på hvilken kjerne spolestammeendestykket er anordnet. • <:: >Med 6 betegnes en tilledningstråd, som fra viklingen 5 folger sporets bunn til det punkt hvor sporet utmunner i rennen, hvor-fra tråden er fritt oppspent til loddefliken 3. Fig. 3 viser et andre ben av samme spolestammeendestykke" i planriss med et parti av viklingen 5, samt dens tilledningstråder 6 og 7 tilknyttet loddeflikene 3 og 4. Fig. 3 viser også sporenes utmunninger 8 i rennene 2, hvilke utmunninger i det viste utforelseseksempel er anordnet inntil respektive rennes ene side. 2 also shows the end portion of a core 4 with associated winding 5, on which core the coil stem end piece is arranged. • <:: >With 6 is denoted a lead wire, which from the winding 5 follows the bottom of the track to the point where the track opens into the channel, from where the wire is freely stretched to the solder tab 3. Fig. 3 shows a second leg of the same coil stem end piece" in plan view with part of the winding 5, as well as its supply wires 6 and 7 associated with the solder tabs 3 and 4. Fig. 3 also shows the openings 8 of the tracks in the channels 2, which openings in the embodiment shown are arranged up to one side of the respective channels.

Etter at en spole er blitt ferdigviklet og tilledningstrådene er loddet fast til loddeflikene, slakkes tilledningstrådene ved at loddeflikene b©yes ned mot rennebunnen. For å forhindre at tilledningstrådene, slik tilfellet ofte sr ved kjente spoleendestyk-kekonstruksjoner, kommer i beroring med nærliggende viklingslag, tilsluttes ifolge oppfinnelsen spormunningene for loddeflikene nedbbues. På det viste utforelseseksemplet, som er utfort i et termoplastisk isolermateriale, har tilslutningen av spormunningene skjedd ved at et varmt spissformig verktoy er blitt presset mot de aktuelle rennenes bunner ,ved 9 og 10, hvorved materialet i rennebunnen,har flytt ut og tilsluttet munningene. Ved sporenes utforming med smale munninger fås dels den fordel at munningene er lette å tilslutte, dels at rennebunnene ved siden av munningene inneholder tilstrekkelig med materiale for å muliggjore nedvarming og tilslutning av sporene. Sporene kan selvfølgelig tilsluttes på annen måte, eksempelvis med.en lim dråpe eller ved inftpressing av et kileformet plaststykke. After a coil has been wound and the lead wires are soldered to the solder tabs, the lead wires are loosened by bending the solder tabs down towards the bottom of the gutter. In order to prevent the supply wires, as is often the case with known coil end-piece constructions, from coming into contact with nearby winding layers, according to the invention, the slot mouths for the solder tabs are connected down. In the embodiment shown, which is made of a thermoplastic insulating material, the connection of the slot mouths has taken place by a hot pointed tool being pressed against the bottoms of the channels in question, at 9 and 10, whereby the material in the bottom of the channel has flowed out and connected the mouths. By designing the tracks with narrow mouths, the advantage is partly that the mouths are easy to connect, and partly that the troughs next to the mouths contain sufficient material to enable cooling and connection of the tracks. The tracks can of course be connected in another way, for example with a drop of glue or by pressing in a wedge-shaped piece of plastic.
