Description

Uppfinnare: H L Naimer och F Bauer Prioritet begdrd !rem den 28 november 1957 (Osterrike) Vid konstruktion av elektriska stromstallare, vilka arbeta med kampa'verkade brytare, gar man sa tillvaga, da det Oiler en strornstallare, medelst vilken man skall kunna beharska ett komplicerat kopplingsprogram, att man anordnar det erforderliga antalet delstromstallare, dvs. »stronastallare fOr olika kopplingsfunktioner, axiellt efter varandra, varvid dessa delstromstallare kunna pkverkas medelst ett gemensamt genomgaende, widningsoverforande organ och ett gemensamt vred. Delstromstallarna eller stromstallarna for olika kopplingsfunktioner sammanhallas ofta medelst dragbultar, vilka genomlopa samtliga de i rad liggande delstrOmstallarna. Inventors: HL Naimer and F Bauer Priority requested on 28 November 1957 (Austria) In the construction of electric switches, which work with combat-switched switches, it is said that it is a current generator, by means of which one can master a complicated switching program, that you arrange the required number of substators, ie. »Strona switches for different coupling functions, axially one after the other, whereby these substers can be actuated by means of a common through-going, widening-transmitting member and a common knob. The subst stables or stables for different coupling functions are often held together by means of tension bolts, which run through all the sub-stalls lying in a row.

En stromstallare av den ovan beskrivna typen omfattar emellertid icke blott delstrOmstallare, utan aven andra konstruktionsenheter, vilka ovillkorligen erfordras for dess avsedda anvandning, exempelvis en sparrmekanism, lasanordningar, vilka aro lasbara me-deist en nyckel och omojliggora en otillborlig paverkan av strOmstallaren, anordningar for att mojliggora anbringandet av ett pasattbart handtag, kopplingssignalanordningar, som indikera den genomforda kopplingen till en avlags en kontrollstation, oversattningsanordningar, vilka mekaniskt overfora kopplingsforloppet till en angransande anordning av annat slag, vilken anordning aven kan vara en andra strOmstallare, osv. Da nu de fordringar, som kunna stallas pa en. strOmstallare uppenbarligen kunna vara av mycket olika slag, men a andra sidan mojligast enhetliga delstromstallare bOra anvandas med tanke pa rationell tillverkning, uppstar behovet av en enkel och andamalsenlig anordning, for att de namnda konstruktionsenheterna ,skola kunna forbindas med varandra och med den angransande delstronastallaren, varvid denna anordning skall vara enhetlig for alla namnda konstruktionsenheter, avensom for dylika av annat slag. However, a switch of the type described above comprises not only partial switches, but also other construction units which are unconditionally required for its intended use, for example a locking mechanism, locking devices which are lockable by means of a key and prevent an undue influence on the power supply. to enable the fitting of an adjustable handle, coupling signal devices indicating the through connection to a remote control station, translation devices which mechanically transfer the coupling process to an adjacent device of another kind, which device may also be a second current switch, etc. Then now the claims, which can be placed on one. Power generators can obviously be of very different types, but on the other hand as uniform as possible sub-generators should be used with a view to rational manufacture, the need arises for a simple and disproportionate device so that the said construction units can be connected to each other and to the adjacent sub-throttle. wherein this device shall be uniform for all said construction units, except for such of another kind.

Enligt ett annat forslag har fOrordats att utrusta hada sidorna av delstriimstallarna eller de liknande konstruktionsenheterna med utsprang resp. urtagningar, vilka samverka som bajonettvridkopplingar. Man kan dã sakert och lageshesta.mt koppla godtyekliga slag av konstruktionsenheter med varandra, forutsatt att de ha denna forbindningsmojlighet. According to another proposal, it has been recommended to equip the sides of the sub-strip stables or the similar construction units with projections resp. recesses, which cooperate as bayonet swivels. One can then securely and legally equip any type of construction unit with each other, provided that they have this connection capability.

Foreliggande uppfinning banfOr sig avenledes till problemet med lagesbestamd koppling av konstruktionsenheter av namnda slag och bestar huvudsakligen dari, att vid delningsytan mellan tva, angransande konstruktionsenheter tillhorande hus eller husdelar aro anordnade porfilerade spar, vilka i den sammanbyggda stromstallaren ligga mitt emot varandra och tillsammans med varandra bilda en gemensam kanal, som or oppen utat och i vilken ett motsvarande hopkopplingsstycke ar inskjutbart. The present invention relates to the problem of statutory coupling of construction units of the type mentioned and consists mainly in that at the dividing surface between two adjacent construction units belonging to houses or house parts there are arranged porphilated grooves, which in the assembled generator lie opposite each other and together with each other. form a common channel, which is open to the outside and into which a corresponding connecting piece can be inserted.

Uppfinningen beskrives i detalj i det foljande under hanvisning till bifogade ritning, dar fig. 1 visar en sidovy av en stromstallare, somi best& av tre delstromstallare och en sparrmekanism. Fig. 2 visar ett snitt utefter linjeni fig. 1 och fig. 3 visar ett snitt utefter linjeni fig. 2. Fig. 4 visar en frontvy av en annan utforingsform och fig. 5 visar en sidovy hartill. Fig. 6 och 7 visa de detaljer av de ovanna.mnda kopplingarna. Det bOr observeras att foreliggande uppfinning i forsta hand avser att astadkomma en lagesbestamd fOrbindning av en tillsatskonstruktionsdel av ovan angivet slag med en delstromstallare och mindre att astadkomma forbindning av delstromstallare med varandra. Dock or uppfinningens anvandning f Or sistnO.mnda andamal joke utesluten. The invention is described in detail in the following with reference to the accompanying drawing, in which Fig. 1 shows a side view of a switch, which consists of three substers and a ratchet mechanism. Fig. 2 shows a section along the line in Fig. 1 and Fig. 3 shows a section along the line in Fig. 2. Fig. 4 shows a front view of another embodiment and Fig. 5 shows a side view thereof. Figs. 6 and 7 show the details of the above-mentioned connections. It should be noted that the present invention is primarily intended to provide a layered connection of an auxiliary structural member of the above type with a sub-switch and less to effect a connection of sub-switches to each other. However, the use of the invention for the latter andamal joke is excluded.

I fig. 1 aro tae delstrOmstallare 1 visade jamte en sparrmekanism 2, som till 2— — det yttre icke kan skiljas fran desamma och som pa nagot satt, exempelvis me-deist den ovannamnda bajonettkopplingen, är forbunden med frontplattan 3. Beteckningen 4 avser en till paverkan av stromstallaren tjanande vridbar axel, som uppbar ett (icke visat), vred. Frontplattan 3 kan ph allmant kfint salt vara fast vid en kopplingstavla eller dylikt. For uppfinningstanken är del, sasom framgatt ovan, likgiltigt om konstruktionsenheterna 1 utgoras av delstrOmstallare eller av konstruktionsenheter av annat slag. Vid delningsytorna 5 mellan de till varandra angransande konstruktionsenheterna 1 och. 2 bildas nu underskurna spar 6 med sidourtagningar 7, vilka spar vid sammanbyggd stromstallare komplettera varandra parvis och tillsammans med varandra bilda en gemensam kanal, som är oppen utat och i vilken ett motsvarande hopkopplingsstycke 8, 8a eller 8b är inskjutet. Tre olika utforingsmojligheter av dessa hopkopplingsstycken bland ett avsevart storre antal mojliga utforingsformer arc visade. For det visa-de exemplet är det vasentligt, att hopkopplingsstyckena pa grund av sin sarskilda profilering aro i stand att sitta pa sadant satt I de varandra till en kanal kompletterande -underskurna sparen, att ett axiellt a.tskiljande av tvâ pa detta salt forbundna konstruktionsenheter dr uteslutet och att samtidigt sakerhet mot relativ vridningsrorelse mellan de bada konstruktionsenheterna är tryggad. In Fig. 1 the sub-switch 1 is shown together with a ratchet mechanism 2, which to the outside cannot be separated from the same and which in some way, for example by means of the above-mentioned bayonet coupling, is connected to the front plate 3. The designation 4 refers to a to the effect of the switch serving rotatable shaft, which carried a (not shown) knob. The front plate 3 can be generally fine salt attached to a switchboard or the like. For the concept of invention, a part, as stated above, is irrelevant if the construction units 1 consist of partial converters or of construction units of another kind. At the dividing surfaces 5 between the adjacent construction units 1 and. 2, undercut grooves 6 are now formed with side recesses 7, which grooves in a combined generator complement each other in pairs and together form a common channel, which is open outwards and into which a corresponding connecting piece 8, 8a or 8b is inserted. Three different embodiments of these interconnectors among a considerably larger number of possible embodiments arc shown. For the example shown, it is essential that the connecting pieces, due to their special profiling, be able to sit in such a way as to complement each other to form a channel-undercut groove, that an axial separation of two structural units connected to this salt dr excluded and that at the same time safety against relative torsional movement between the two construction units is ensured.

Fig. 2 ger en inblick i det inre av en delstromstallare och askadliggor hunt man kan anordna de ovannamnda kanalerna. I fig. 2 och 3 arc de viktigaste delarna i en stromstallare av en ofta fOrekomman.de konstruktion inritade utan att alla detaljerna aro askadliggjorda. Det skall blott visas, att i praktiken fdrefinnes i huvudsak mOjlighet att genomfOra de fOr uppfinningens tillampning erforderliga konstruktionsandringarna pa vanliga konstruktionsenheter. Exempelvis har en. sparrm.ekanism en mekanisk konstruktion, som i manga avseenden ar mycket Ilk konstruktionen hos den i fig. 2 visade stromstallaren. Fig. 2 gives an insight into the interior of a substator and ash trays can be arranged the above-mentioned channels. In Figs. 2 and 3 the most important parts of a switch of a frequently occurring construction are drawn without all the details being damaged. It is only to be shown that in practice it is essentially possible to carry out the design changes required for the application of the invention on ordinary design units. For example, one has. sparrm.ekanism a mechanical construction, which in many respects is very similar to the construction of the switch shown in Fig. 2.

Beteckningen 10 avser ett burkformigt, av plast bestaende hus, som Or Oppet mot en sida. Locket till detta hus utgor samtidigt botten i nasta konstruktionsenhet. Beteckningen 11 avser stromstallarens vridbara axel, pa vilken Or anbragt en kamskiva 12, som via rullar 13 och lyftstanger 14, vilka kunna bringas att glida i styrningar 15, paverkar kontaktbryggor 16, som stâ under paverkan av tryckfjadrar 17. Bryggorna 16 kunna forskjutas mot fjadrarnas 17 verkan genom vridning av kamskivan. 12, varigenom de bryta den av motkontakterna 18 och anslutningsklammorna 19 definierade strombanan. Delta konstruktionssatt for stromstallare Or vanligt, varfor det icke synes vara nodvan digt att ga in pa ytterligare detaljer, vilka for avrigt icke Ore visade. I mellanrummen mellan kopplingsbryggorna 16 aro nu anordnade sparen 6, vilka komplettera varandra till en kanal, for vilket andamal ansatser 21 Oro utformade i huset 1. Hopkopplingsstyckena aro ater betecknade 8. The designation 10 refers to a jar-shaped, plastic housing, which is facing one side. The lid of this house also forms the bottom of the nearest construction unit. The designation 11 refers to the pivotable shaft of the switch, on which Or is mounted a cam disc 12, which via rollers 13 and lifting rods 14, which can be made to slide in guides 15, actuates contact bridges 16, which are under the influence of compression springs 17. The bridges 16 can be displaced against the springs 17 effect by rotating the cam disc. 12, whereby they break the current path defined by the counter-contacts 18 and the connection clamps 19. Delta construction set for power stalls Or usual, for which it does not seem necessary to go into further details, which otherwise Ore did not show. In the spaces between the coupling bridges 16 there are now arranged the grooves 6, which complement each other to a channel, for which purpose the shoulders 21 are formed in the housing 1. The connecting pieces are again denoted 8.

Det torde vara tydligt, att den i fig. 1-3 visade utforingsformen arbetar med radiellt insattbara hopkopplingsdelar eller hopkopplingsstycken 8. Fig. 4 och 5 visa ett konstruktionssatt hos kopplingsdelar, vilka Oro inskjutbara tangentiellt med konstruktionsenhetens hus. I fig. 4 och 5 Oro samma delar som i fig. 1-3 forsedda med samma beteckfinger. Sparen 6, vilka komplettera varandra till kanaler med en underskuren profit, Oro i detta fall anordnade i vulster 24 pa husets utsida. It should be clear that the embodiment shown in Figs. 1-3 works with radially insertable coupling parts or connecting pieces 8. Figs. 4 and 5 show a construction set of coupling parts, which are displaceable tangentially with the housing of the construction unit. In Figs. 4 and 5, the same parts as in Figs. 1-3 are provided with the same index finger. The savings 6, which complement each other to channels with a undercut profit, Oro in this case arranged in beads 24 on the outside of the house.

Det torde vara uppenbart, att hopkopplingsstyckena enligt uppfinningen ha talrika utforingsformer, icke blott med avseende pa sin profilering utan Oxen med hansyn till silt relativa lage i de medelst desamma forbundna konstruktionsenheterna. Av fig. 6 framgar, att det genom en motsvarande formgivning av kopplingsdelen 8 ocksa Or mojligt att sa fasthalla de hada angransande konstruktionsenheterna 1 i forhallande till varandra, att dessa konstruktionsenheter ligga mitt for varandra med ett avstand a dem emellan. liven denna tanke kan forverkligas under anvandning av spar, vilka Oro utformade pa de mest olika sat, samt av hopkopplingsstycken, vilka motsvara dessa spar. It should be obvious that the connecting pieces according to the invention have numerous embodiments, not only with regard to their profiling but the Taurus with regard to the silt relative position in the construction units connected by the same means. It can be seen from Fig. 6 that by means of a corresponding design of the coupling part 8 it is also possible to hold the adjacent adjacent construction units 1 in relation to each other, that these construction units lie opposite each other with a distance between them. This idea can be realized through the use of tracks, which are designed in the most different ways, as well as of connecting pieces, which correspond to these tracks.

Vid de visade utforingsexemplen har antagits, att hopkopplingsstyckena mer eller mind-re utan spel passa in i de dem upptagande kanalerna. For att hopkopplingsstyckena skola fasthallas friktionsfast i kanalerna Or det I regel fordelaktigt att utfora kanalerna och/ eller hopkopplingsstykena med en i de senares inskjutningsriktning avsmalnande form, dvs. kilform. Det Or emellertid ocksa mojligt att an.ordna deformationsmojligheter f Or hopkopplingsstyckena eller ocksa for de tunnare vaggpartierna, som begransa kanalerna, for att detta mal skall uppnas. Det Or vidare miijligt, att forse hopkopplingsstyckena med utsprang, vilka da. hopkopplingsstyckena inskjutas i de kanaler, vilka aro anordnade att upptaga desamma, bringas att vila I urtagningar i dessa kanaler, for vilket andamal hopkopplingsstyckena maste vara framstallda av ett material med tillracklig elasticitet. Slutligen kan man fasthalla hopkopplingsstyckena i kanalerna medelst limning under anvandning av ett lampligt lim. In the embodiments shown, it has been assumed that the connecting pieces more or less without play fit into the channels receiving them. In order for the connecting pieces to be held frictionally fixed in the channels, it is generally advantageous to design the channels and / or the connecting pieces with a shape which tapers in the direction of insertion of the latter, ie. wedge shape. However, it is also possible to provide deformation possibilities for the connecting pieces or also for the thinner rock sections which delimit the channels, in order to achieve this goal. It is also possible to provide the connecting pieces with projections, which then. the connecting pieces are inserted into the channels which are arranged to receive them, are brought to rest in recesses in these channels, for which purpose the connecting pieces must be made of a material with sufficient elasticity. Finally, the connectors can be secured in the channels by gluing using a suitable glue.

En sarskild fordel med foreliggande fasthallningssatt ligger dari, att man vid utfOrandel av den elektriska kopplingen kan atskilja de enskilda konstruktionsenheterna fran varandra, vilket medfbr dels att man vid delstromstallare lattare kan n0. anslutningsklam- — —3 morna, dels att man, da man salunda har mOjlighet att kunna nä utgangsklammorna, nu kan konstruera ur andra synpunkter an vad som är mojligt vid stromstallare I sadana fall, dar den elektriska kopplingen maste utforas utan att stromstallaren kan isartagas till delstromstallare. A special advantage of the present restraint system is that when the electrical connection is carried out, the individual construction units can be separated from each other, which means that in the case of substers it is easier to reach. connection terminals, and that, since it is thus possible to reach the output terminals, one can now construct from other points of view what is possible with the switch In such cases, where the electrical connection must be made without the switch being disassembled to partial current stall.

Husdelarna 1 besta vid modern massfabrikation i regel av plast. Under bibehallande detta konstruktionsmaterial kunna de i foreliggande fall erforderliga kanalerna i husdelarna utan svarighet framstallas. Hopkopplingsstyckena kunna lampligen framstallas av en termoplast och man kan darvid aven ga sa tillvaga, att ett flertal hopkopplingsstycken 8 hanga fast med det inbordes avstandet b vid en gemensam forbindningsdel eller ett forbindelsestycke 30 (fig. 7), varvid de behalla namnda avstand aven i den fardiga stromstallaren. Da bildar denna sarskilda forbindningsdel 30 med de darifran utgaende hopkopplingsstyckena en kamliknande anordning, som kan overtaga sakringen mot husdelarnas atskiljande i axiell riktning. I detta fall behova de kanaler, som upptaga hopkopplingsstyckena, icke ovillkorligen ha en underskuren profil, emedan hopkopplingsstyckena da enbart ha till uppgift att tj anstOra som sfikring mot vridning, under det att delstromstallena sammanhallas i axiell riktning medelst forbindningsdelen 30. The housing parts 1 consist of modern mass production, usually of plastic. While maintaining this construction material, the necessary channels in the housing parts in the present case can be manufactured without liability. The connecting pieces can suitably be made of a thermoplastic and it can also be said that a plurality of connecting pieces 8 are attached to the in-space distance b at a common connecting part or a connecting piece 30 (Fig. 7), whereby they retain said distance even in the finished power stall. Then this special connecting part 30 with the connecting pieces emanating therefrom forms a cam-like device which can take over the fuse against the separation of the housing parts in the axial direction. In this case, the channels which receive the connecting pieces do not necessarily have to have a undercut profile, since the connecting pieces then only have the function of serving as a protection against rotation, while the subst stables are held together in the axial direction by means of the connecting part 30.

Uppfinningen kan awn tillampas for sadana elektriska apparater, som, utan att vara stromstallare, besta av flera axiellt eller varandra anordnade konstruktionsenheter. The invention can be applied to such electrical devices which, without being power generators, consist of several axially or mutually arranged structural units.
