Description
Oppfinnelsen angår en innretning til prøving av elektriske ledninger i fordelere for telekommunikasjonsanlegg, spesielt telefonanlegg. The invention relates to a device for testing electrical cables in distributors for telecommunications systems, especially telephone systems.
Fra DE-PS 20 48 104 er det kjent å montere en fordeler bestå-ende av flate sjiktkomponenter, som er forsynt med rekker av tilkoblingselementer for de elektriske ledningene. Tilkoblingselementene strekker seg tilnærmet rettlinjet fra fordelerens forside til det indre av sjiktkomponenten og danner der skillekontaktpunkter mellom de utvendige og innvendige ledninger i fordeleren. Skillekontaktpunktene kan skilles ved hjelp av enkle pluggtunger av isolasjonsmateriale som likeledes kan plugges inn fra forsiden ved hjelp av spesielle pluggkanaler mellom tilkoblingselementparene. From DE-PS 20 48 104, it is known to mount a distributor consisting of flat layer components, which are provided with rows of connection elements for the electrical cables. The connection elements extend in an approximately straight line from the front of the distributor to the interior of the layer component and there form separating contact points between the external and internal wires in the distributor. The separate contact points can be separated using simple plug tongues made of insulating material which can also be plugged in from the front using special plug channels between the pairs of connection elements.
Ved nyinstallasjon, utvidelse eller ved utskifting av gamle med moderne sentralanlegg er det videre kjent å forkable fordelerne helt og avbryte ledningene til den endelige ferdigstilling av anlegget, ved hjelp av skilleplugger som strekker seg over hele bredden av en sjiktkomponent. En slik multippel plugg er f.eks. gjengitt i Siemens-katalogen "Schwachstromverteilerein-richtungen in lotfreier Anschlusstechnik", Zustand mars 1981, side 50. Da skillepluggene skal plugges inn i samtlige nyan-brakte sjiktkomponenter hindrer de den frie adgang til den ytre sone av tilkoblingselementene for prøvingsformål. Slike led-ningsprøver må foretas før innkoblingen av anlegget. Prøvingen skjer ved hjelp av prøvesnorer som viser tilkoblingselementene formet i samsvar med prøvespisser. En slik påsetting av prøve-snorer er særlig vanskelig ved høyt anbragte sjiktkomponenter. In the case of new installation, expansion or when replacing old with modern central systems, it is also known to completely pre-wire the distributors and disconnect the cables until the final completion of the system, using separation plugs that extend over the entire width of a layer component. Such a multiple plug is e.g. reproduced in the Siemens catalog "Schwachstromverteilerein-richtungen in lotfreier Anschlusstechnik", Zustand March 1981, page 50. As the separation plugs must be plugged into all newly introduced layer components, they prevent free access to the outer zone of the connection elements for testing purposes. Such wiring tests must be carried out before switching on the system. The test is carried out using test cords that show the connection elements shaped in accordance with test tips. Such fitting of test cords is particularly difficult with highly placed layer components.
Oppfinnelsens hensikt er å lette prøvearbeidet.The purpose of the invention is to facilitate the test work.
Denne hensikt oppnås ved en innretning av den i innledningen til krav 1 angitte art, som er kjennetegnet ved det som er angitt i den karakteriserende del. Tilkoblingspunktene for prøvesnorene befinner seg nå utenfor tilkoblingselementene på sjiktkomponenten og er dermed betydelig lettere tilgjengelige. Skillepluggene kan på sin utvendige kant være utført slik at tilkoblingsmidlet for prøvesnoren på enkel og sikker måte kan påsettes. Prøvesnorene kan f.eks. være forsynt med stikkontakter som skyves inn på skillepluggens kontaktsoner. This purpose is achieved by a device of the type specified in the introduction to claim 1, which is characterized by what is specified in the characterizing part. The connection points for the test cords are now outside the connection elements on the layer component and are thus considerably easier to access. The separating plugs can be designed on their outer edge so that the connecting means for the test cord can be attached in a simple and safe way. The test cords can e.g. be provided with sockets that are pushed into the contact zones of the separation plug.
I henhold til en videreutvikling av oppfinnelsen er skillepluggen utført som et trykt kretskort. Dette muliggjør en kostnads-gunstig fremstilling av skillepluggen, idet kontaktflatene og kontaktsonene så vel som strømløpene fremstilles i et arbeidstrinn. According to a further development of the invention, the separation plug is designed as a printed circuit board. This enables a cost-effective production of the separation plug, as the contact surfaces and contact zones as well as the current paths are produced in one work step.
I henhold til en annen videreutvikling av oppfinnelsen er skillepluggene utført som tosidig trykte kretskort. Derved er det mulig å prøve ledninger som fra fordeleren fører både til utsiden og innsiden uten at skillepluggenes stilling må forandres. According to another further development of the invention, the separating plugs are designed as double-sided printed circuit boards. Thereby, it is possible to test cables that lead from the distributor to both the outside and the inside without the position of the separator plugs having to be changed.
I det følgende skal oppfinnelsen forklares nærmere ved hjelp av et på tegningen vist utførelseseksempel. In the following, the invention will be explained in more detail with the help of an embodiment shown in the drawing.
Den viste figur viser skjematisk i perspektiv to rekker av tilkoblingselementer 1 av en ikke nærmere vist sjiktkomponent for en fordeler i en telefonsentral og med en skilleplugg 2 The figure shown schematically shows in perspective two rows of connection elements 1 of a layer component not shown in detail for a distributor in a telephone exchange and with a separating plug 2
og stikkontakter 3 på ikke nærmere viste prøvesnorer.and sockets 3 on test leads not shown in more detail.
Hver rekke av tilkoblingselementer 1 tjener til tilkoblingEach row of connection elements 1 serves for connection
av interne resp. eksterne ledninger 4. Tilkoblingselementene 1 strekker seg fra tilkoblingspunktene for ledningen 4 rettlinjet inn i det indre av sjiktkomponenten og danner ved sine innvendige ender skillekontaktpunkter 5 som adskilles ved deri-mellom innskjøvne pluggtunger 6 på skillepluggen 2. Pluggtungene 6 har i området av skillekontaktpunktene 5 kontaktflater 7 som står i kontakt med skillekontaktpunktet 5. Fra kontaktflatene 7 strekker det seg trykte strømløp 8 til de utvendige kanter av skillepluggen 2 hvor de ender i kontaktsoner 9 for stikkontaktene 3. Kontaktsonene 9 ligger utenfor de frie ender av tilkoblingselementet 1 og er dermed lett tilgjengelig for prøvesnorene. Skillepluggen 2 er utført som et tosidig trykt kretskort, slik at ledninger 4 som fører såvel til utsiden som til innsiden kan prøves. of internal or external cables 4. The connection elements 1 extend from the connection points for the cable 4 in a straight line into the interior of the layer component and form at their inner ends separation contact points 5 which are separated by plug tongues 6 inserted in between on the separation plug 2. The plug tongues 6 have contact surfaces in the area of the separation contact points 5 7 which is in contact with the separation contact point 5. From the contact surfaces 7, printed current flows 8 extend to the outer edges of the separation plug 2 where they end in contact zones 9 for the sockets 3. The contact zones 9 lie outside the free ends of the connection element 1 and are thus easily accessible for the test cords. The separation plug 2 is designed as a double-sided printed circuit board, so that wires 4 leading both to the outside and to the inside can be tested.
