(54) Element til koble- og/eller skillelister i fordelere til telekommuni® kationsanlæg samt fremgangsmåde til fremstilling af sådanne elementer.(54) Element for coupling and / or separating lists in distributors for telecommunications® cation systems as well as the method for producing such elements.

Den foreliggende opfindelse angår et element til koble- og/eller skillelister i fordelere til telekonmunikationsanlæg, især telefonformidlingsanlæg, hvilket element i sin ene ende har et klemmeorgan til afisoleringsfri tilslutning af elektriske ledere og i sin anden ende har en kontaktfjeder, som sammen med kontaktfjederen i et naboelement danner en skille- eller koblekontakt, idet klemme-organet er fremstillet i ét stykke med kontaktfjederen af fjederblik.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an element for switching and / or separating strips in distributors for telecommunication systems, in particular telephone switching systems, which element has at one end a clamping means for the free isolation of electrical conductors and at its other end has a contact spring which together with the contact spring in a neighboring member forms a separating or coupling contact, the clamping member being integrally formed with the spring contact contact spring.

Ved sådanne elementer er det ønskeligt, dels at klenaneorganet har tilstrækkelig stor stabilitet til, når lederen indføres, at kunne forhindre en deformation af de kæber, der begrænser indføringsslidsen, dels at der i kontakt-fjederområdet er så stor elasticitet, at der til forbindelse med og adskillelse fra kontaktfjederen i et naboelement kræves mindst mulige kontaktfjederkræfter. Opfindelsen tager sigte på at tilvejebringe et element, der til trods 2 141222 for enkel konstruktion opfylder de nævnte ønsker.In such elements, it is desirable, firstly, that the clenane member has sufficient stability to allow the conductor to prevent deformation of the jaws that restrict the insertion slot, and secondly that in the contact spring region there is so much elasticity that the and separation from the contact spring in a neighboring element requires the least possible contact spring forces. The invention has for its object to provide an element which, in spite of simple construction, fulfills the said wishes.

Denne opgave løses ved, at materialetykkelsen af fjederblikket i området ved kontaktfjederen er mindre end i området ved klemmeorganet. Et med forskellig materialetykkelse udvalset fjederblik med gode elastiske egenskaber muliggør nu ved sin tykkere ende at udforme et klemmeelement med en eller to tilslutningsmuligheder med den til dette anvendelsesformål nødvendige store stabilitet ved indføringen af lederen. I det andet, tyndere endeområde kan der udformes en kontaktfjeder med den ønskede store elasticitet og deraf følgende væsentligt mindre kontaktkræfter.This problem is solved by the fact that the material thickness of the spring tin in the area of the contact spring is less than in the area of the clamping member. A spring plate selected with different material thickness, with good elastic properties, now enables at its thicker end to form a clamping element with one or two connection possibilities with the great stability required for this application when introducing the conductor. In the second, thinner end region, a contact spring can be formed with the desired high elasticity and consequently substantially less contact forces.

En rationel fremgangsmåde til fremstilling af flere elementer ifølge opfindelsen kan opnås ved, at der i et første skridt sker formindskelse af materialetykkelsen ved valsning, og at elementernes konturer udstanses i et yderligere skridt. Efter stansningen af elementernes konturer kan elementerne først forblive indbyrdes forbundet over materialestykker og i deres helhed i deres kontaktgivende områder, dvs. ved kontaktfjederen og klemmeorganet, delvis blive underkastet en overfladebehandling, f.eks. en forsølvning. Ved en sådan fremgangsmåde, i hvilken de udstansede bånd kun bliver delvis overfladebehandlet under gennemgangsfremgangsmåden og eventuelt også kemisk afgratet, kan der dels spares dyre ædelmetaller, dels undgås ved færdiggørelsen af separate elementer optrædende vanskeligheder.A rational process for producing several elements according to the invention can be achieved by reducing the thickness of the material by rolling in a first step and cutting the contours of the elements in a further step. After the punching of the contours of the elements, the elements can first remain interconnected over pieces of material and in their entirety in their contact-giving regions, ie. at the contact spring and clamping means, partially subjected to a surface treatment, e.g. a silver lining. In such a method, in which the punched bands are only partially surface treated during the review process and possibly also chemically degraded, expensive precious metals can be saved and partly avoided by the completion of separate elements occurring difficulties.

Opfindelsen forklares i det følgende nærmere på grundlag af flere udførelseseksempler under henvisning til tegningen, idet fig. 1 viser et element med en klemmetilslutning til en elektrisk leder, fig. 2 elementet med klemmetilslutning til to elektriske ledere og en yderligere øverste fjeder, fig« 3 elementet med klemmetilslutning til to elektriske ledere, fig. 4-6 enkelte skridt ved fremgangsmåden til fremstilling af elementet, fig. 7 og 8 det i henhold til denne fremgangsmåde fremstillede element set fra owen og fra siden, fig. 9 det med en ekstradel, her en tilslutningskontakt til beskyttelsesstik, forbundne element ifølge fig. 7 og 8, fig. 10-12 det med en som loddetilslutning udformet ekstradel forbundne element, hvorved der med disse loddetilslutninger kan gennemføres forskellige koble-funktioner, fig. 13 et sidesnit af et skilleelement i fordeleranlæg, som er opbygget med det ifølge opfindelsen tilvejebragte element, fig. 14 et snit gennem linjen A-B ifølge fig. 13 og fig. 15 et sidebillede af det med en ekstradel forsynede element.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail on the basis of several embodiments with reference to the accompanying drawings, in which: FIG. 1 shows an element with a clamp connection to an electrical conductor; FIG. 2 shows the element with clamp connection for two electric conductors and a further upper spring; fig. 3 the element with clamp connection for two electric conductors, fig. 4-6 single steps in the process of manufacturing the element; Figures 7 and 8 show the element made according to this method as viewed from the side and from the side; 9 shows the element connected to an external part, here a connecting contact for protective plugs according to FIG. 7 and 8, FIG.

Det i fig. 1 viste element består af et fjederhårdt båndmateriale, som med hensyn til sin materialetykkeIse i kontaktgivende områder er udformet forskelligt.The FIG. 1 is a spring-hard ribbon material which is designed differently for its material thickness in contact-giving areas.

3 1412223 141222

Dette element består af en klemme 2, som danner det ene endeområde,og som her tjener til den afisoleringsfrie tilslutning af en elektrisk leder, og en kontaktfjeder 3, som danner det andet endeområde. Da der til klemmeelementet 2, afhængigt af dets anvendelse og med hensyn til stabiliteten ved indklemningsforløbet, stilles andre krav end til kontaktfjederen 3, har dette element 1 i området for klemmeelementet 2 ca. på halvdelen af sin længde en større materialetykkeIse (f.eks. 0,8 mm) end i den anden halvdel i området for kontaktfjederen (f.eks.This element consists of a terminal 2, which forms one end region, which serves here for the de-insulation-free connection of an electrical conductor, and a contact spring 3 which forms the other end region. Since, for its clamping element 2, depending on its use and with respect to the stability of the squeezing process, other requirements than the contact spring 3 are made, this element 1 in the region of the clamping element 2 has approx. a half of its length has a greater material thickness (eg 0.8 mm) than in the other half in the area of the contact spring (e.g.

0,6 mm). Som dét senere forklares, sker formindskelsen af materialetykkelsen f. eks. ved valsning. De enkelte kontaktgivende områder (klemmeelement og kontaktfjeder) danner en vinkel med hinanden, da kontaktfjedéren 3 skal danne en slutte- eller brydekontakt med kontaktfjederen på et naboelement, således som vist f.eks. i fig. 11 og 12.0.6 mm). As will be explained later, the reduction of material thickness occurs, for example, by rolling. The individual contacting areas (clamping element and contact spring) form an angle with each other, as the contact spring 3 is to form a closing or breaking contact with the contact spring on a neighboring element, as shown e.g. in FIG. 11 and 12.

Det i fig. 2 viste element 4, som tjener til afisoleringsfri tilslutning af to isolerede ledere, er sammensat af en i ét stykke med kontaktfjederen 5 fremstillet klemmedel 6, som på sin ende har et midterstykke 7, og en separat, f.eks. af kobber-beryllium bestående,komponent 8. Derved er midterstykket 7 forkrøppet således, at det kommer til at ligge i planet for den separate komponent, f.eks. den øverste fjeder, så at begrænsningen af de to klemmeslidser 9 sker dels ved hjælp af det forkrøppede midterstykke, dels ved hjælp af den øverste fjeder 8.The FIG. 2, which serves for the de-insulation-free connection of two insulated conductors, is composed of a clamping means 6 made in one piece with the contact spring 5, which at its end has a center piece 7, and a separate, e.g. of copper-beryllium, component 8. Thereby, the center piece 7 is curved such that it will lie in the plane of the separate component, e.g. the upper spring, so that the restriction of the two clamping slots 9 occurs partly by means of the crimped center piece and partly by the upper spring 8.

Ved det i fig. 3 viste element 10, som ligeledes tjener til afisolerings-fri tilslutning af to elektriske ledere, dannes klemmeslidserne på kendt måde af i et plan liggende endestykker 12 og et mellem disse anbragt midterstykke 11.In the embodiment shown in FIG. 3, which also serves for de-insulation-free connection of two electrical conductors, the clamping slots are formed in a known manner by end ends 12 lying in a plane and a middle piece 11 arranged between them.

I fig. 4 til 8 vises enkelte skridt ved fremgangsmåden til fremstilling af elementet ifølge fig. 2* Der fremstilles først sammenhængende af båndmaterialet et antal elementer 4 samt separate komponenter 8, som kompletterer elementerne 4, hvorved der i et første trin ved fremgangsmåden sker den nævnte formindskelse af materialetykkelse ved valsning i kontaktfjederområdet for elementet 4, mens konturerne af elementerne 4 og de separate komponenter 8, som kompletterer dem, stanses i et yderligere trin. Efter udstansningen af konturerne bliver elementerne 4 samt de separate komponenter 8, som har den samme delingsafstand, først ved hjælp af materialestykker 14 og 13 forbundet med hinanden, hvorved elementerne 4 son helhed i deres kontaktgivende områder (klemmeelement 15 og 16, kontaktfjeder 17) partielt underkastes en overfladebehandling, f.eks. forsølvning. Denne partielle forsølvning kan f.eks. alene ske i de mellem stiplede linjer 18 og de frie ender af de kontaktgivende dele angivne områder, hvorved der spares på dyre ædelmetaller. Ved sammensætningen af de dele, som danner elementet, i en svejseindretning spredes den øverste fjeder 8 over midterstykket 16, hvorved den ønskede forspænding fremstilles, og derpå optages elementet 4 og den Øverste fjeder 8 i fælles centreringshuller 19. I et yderligere skridt 141222 . 4 ved fremgangsmåden punktsvejses den øverste fjeder 8 og elementet 4 ved stederne 20. Ved hjælp af skillestempler fjernes så materialestykkeme 13 og 14, og de færdige elementer 4 kan anvendes. Til deres fiksering ved anbringelse i på passende måde udførte holdere, f.eks. formstoflegemer på fordeleranlæg, er elementerne forsynet med fastgørelseshuller 22, igennem hvilke en på formstof-legemet anbragt knast griber ind.In FIG. 4 to 8, some steps are shown in the method of manufacturing the element of FIG. 2 * First, a plurality of elements 4 and separate components 8 which are complementary to the elements 4 are first produced coherently by the strip material, whereby, in a first step of the process, said reduction in material thickness occurs by rolling in the contact spring region of the element 4, while the contours of the elements 4 and the separate components 8 which complete them are stopped in a further step. After the punching of the contours, the elements 4 and the separate components 8 having the same parting distance are first connected to each other by means of material pieces 14 and 13, whereby the elements 4 are wholly in their contacting areas (clamping elements 15 and 16, contact spring 17). is subjected to a surface treatment, e.g. silver plating. This partial silvering may e.g. only occur in the areas indicated by dotted lines 18 and the free ends of the contacting parts, thereby saving on precious precious metals. In the assembly of the parts forming the element in a welding device, the upper spring 8 is spread over the center piece 16, thereby producing the desired bias, and then the element 4 and the upper spring 8 are received in common centering holes 19. In a further step 141222. 4 by the method, the top spring 8 and the element 4 are spot welded at the places 20. By means of separating pistons, the material pieces 13 and 14 are removed and the finished elements 4 can be used. For their fixation by placing in appropriately executed holders, e.g. In the case of plastic bodies on distributor systems, the elements are provided with attachment holes 22 through which a cam placed on the plastic body engages.

I fig. 9 til 14 er det ifølge fig. 2 udførte element forsynet med yderligere ekstradele, ved hjælp af hvilke forskellige elektriske funktioner i fordelere kan opfyldes. Dette element 4, som muliggør en dobbelt afisoleringsfri tilslutning af elektriske ledere, er, som det kan ses i fig. 15, forsynet med en forkrøpning 24 omtrent i midten af sin længde mellem klemmeelementet 23 og kontaktfjederen 4, og tjener på dette sted til optagelse og fastgørelse af en yderligere ekstradel 25. Forkrøpningen er derved valgt således, at den i dette område med elementet f.eks. ved punktsvejsning på stedet 26 forbundne ekstradel med sin overflade, som vender bort fra elementet, i det væsentlige ligger i planet for området, som danner klemmeelementet 23. Derved bliver, som det skal forklares senere, skaffet plads til ved fastgørelsen af elementet med en ekstradel at fastgøre denne tilstrækkeligt ind i et formstoflegeme, uden at forøge de ydre dimensioner af forms tof legemet udover den øvers te fjeders plan. Ved dette i fig. 15 viste element 4 har kun det område 27, som tjener til klemningen, en større materialetykkelse.In FIG. 9 to 14, according to FIG. 2 provided with additional extras by means of which various electrical functions of distributors can be fulfilled. This element 4, which allows for a double defrost-free connection of electrical conductors, is, as can be seen in FIG. 15, provided with a crease 24 approximately in the middle of its length between the clamping element 23 and the contact spring 4, and serves at this location to receive and attach an additional extrusion portion 25. The crease is thereby selected so that in this region with the element f. eg. by spot welding on the spot 26, the extradel connected to its surface which faces away from the element is substantially in the plane of the area forming the clamping element 23. This, as will be explained later, provides space for attaching the element with an extradel securely attaching it to a plastic body without increasing the outer dimensions of the mold to the body beyond the plane of the upper tea spring. In this in FIG. 15, only the area 27 which serves the clamp has a greater material thickness.

Ved det i fig. 9 viste udførelseseksempel danner den på elementet 4 ved hjælp af punktsvejsning fastgjorte og som bladfjeder 28 udformede ekstradel en ekstrakontakt til tilslutning af et beskyttelsesstik. Udførelseseksemplet ifølge fig. 10 viser derimod en med elementet 4 forbundet ekstradel, som er udført som båndformet loddetilslutning 29, hvorved dens frie ende 30 er afbøjet i retningen mod det område af elementet, som danner kontaktfjederen. Disse loddetil-slutninger 29 kan påloddes elektroniske komponenter 31 i form af dioder, hvis anden ende er forbundet med en multipelledning 32. Det er også muligt at udforme de båndformede loddetilslutninger lige i deres frie endeområder og at ombøje tilslutningstrådene af elementerne, som dette er antydet i fig. 10 på elementet 31' med de ombøjede tilslutningstråde 30'.In the embodiment shown in FIG. 9 illustrates the attachment fixed to the element 4 by spot welding and as an extra spring, 28 formed as a leaf spring an extra contact for connecting a protective plug. The embodiment of FIG. 10, on the other hand, shows an extradel connected to the element 4, which is designed as a band-shaped solder connection 29, whereby its free end 30 is deflected in the direction towards the region of the element forming the contact spring. These solder connections 29 can be soldered to electronic components 31 in the form of diodes, the other end of which is connected to a multiple conduit 32. It is also possible to design the ribbon solder connections in their free end regions and to bend the connecting wires of the elements as indicated. in FIG. 10 on the element 31 'with the bent connecting wires 30'.

Ved den i fig. 11 viste indretning kan der realiseres en brydekontakt med elementerne 4, hvis loddetilslutninger 33, som er forbundet med kontakten, tjener til tilslutningen af afkoblingsdioder 34 til den nærliggende tilslutning 35. Sådanne skillelister kan anvendes f.eks. til prioritetsrangering i ESK-anlæg.In the embodiment shown in FIG. 11, a switching contact can be realized with the elements 4, whose solder connections 33 connected to the contact serve to connect decoupling diodes 34 to the neighboring connection 35. Such separating strips can be used e.g. for priority ranking in ESC plants.

Udførelseseksemplet ifølge fig. 12 viser det med en loddetilslutning 36 forbundne element 4, der som koblekontakt tilvejebringer en tilslutningsmulighed for elektroniske komponenter 37. Sådanne med kobleelementer opbyggede koblingslister kan anvendes som tilgængelige komponentholdere til en indstikkeligThe embodiment of FIG. 12 shows the solder element 4 connected to a solder connection 36, which provides as a coupling contact a connection option for electronic components 37. Such coupling strips constructed with coupling elements can be used as available component holders for an insertable
