Abstract
Description
Oppfinnelsen vedrører en skjermet modulbærer for styrbare elektroniske koblingsfelt i elektroniske telekommunikasjonsnett. The invention relates to a shielded module carrier for controllable electronic switching fields in electronic telecommunications networks.
Styrbare elektroniske koblingsfelt for overføringskanaler anordnes i nodene til overføringsnettet for veksling og kobling av digitale signaler. Koblingsfeltet består fortrinnsvis av skjermet anordnede moduler standardisert med hensyn på ETSI- (European Telecommunication Standard Institute) byggereglene. Controllable electronic switching fields for transmission channels are arranged in the nodes of the transmission network for switching and connecting digital signals. The connection field preferably consists of shielded arranged modules standardized with regard to the ETSI (European Telecommunication Standard Institute) construction rules.
Modulbærere for skjermede moduler er tidligere kjent. EP Bl 553 399 foreslår for eksempel en modulbærer utformet som et Faraday bur og hvor frontveggene er avtagbare og kan skyves over de øvre vegger. For områdene tilhørende et digitalt elektronisk koblingsfelt, som f.eks. tilknytningsfeltet, nettilknytningen med nettfiltre, sikringene og modulområdene er denne skjerming tilstrekkelig. For de ømfintlige taktmoduler anbefales imidlertid en spesiell skjerming, idet disse elementer kan påvirkes av de omgivende moduler. Module carriers for shielded modules are previously known. EP Bl 553 399 proposes, for example, a module carrier designed as a Faraday cage and where the front walls are removable and can be pushed over the upper walls. For the areas belonging to a digital electronic switching field, such as e.g. connection field, the network connection with network filters, the fuses and the module areas, this shielding is sufficient. However, special shielding is recommended for the sensitive clock modules, as these elements can be affected by the surrounding modules.
Oppfinnelsen har som hensikt å tilveiebringe en modulbærer for moduler, som sikrer skjerming av samtlige moduler mot forstyrrende inn- og utstråling. The purpose of the invention is to provide a module carrier for modules, which ensures shielding of all modules against disturbing input and radiation.
Denne hensikt oppnås med en oppfinnelse karakterisert ved det som angis i den kjennetegnende del av krav 1. This purpose is achieved with an invention characterized by what is stated in the characterizing part of claim 1.
Oppfinnelsen vil i det følgende beskrives nærmere ved hjelp av de vedlagte tegninger, hvor: Figur 1 er et frontriss av en modulbærer med et kontaktfelt på en åpnet frontvegg; Figur 2 viser en forminsket koblingsplate på baksiden av modulbæreren uten skjermende tildekking; The invention will be described in more detail below with the help of the attached drawings, where: Figure 1 is a front view of a module carrier with a contact field on an open front wall; Figure 2 shows a reduced connection plate on the back of the module carrier without a shielding cover;
Figur 3 er et frontriss av modulbæreren uten kontaktfeltet; og Figure 3 is a front view of the module carrier without the contact field; and
Figur 4 er et sideriss av modulbæreren ifølge figur 3. Figure 4 is a side view of the module carrier according to Figure 3.
I alle figurene har de samme deler samme henvisningstall. In all the figures, the same parts have the same reference numbers.
Modulbæreren er delt i to områder, et av dem omfattende tilkoblingsområdet med tilkoblings felt 10, netttilkoblingsområde 11 og sikringer for modulområdet 20. Modulområdet 20 skjermes ved hjelp av en utklaffbar frontvegg 21 og samtlige modulbærere skjermes ved hjelp av en bakre skjermende tildekking 22, som dekker og skjermer modulområdet 20, tilkoblingsfeltet 10, nettilkoblingsområdet 11 og den metalliske koblingsplate 24.1 tillegg er tilkoblingsfeltet 10 og nettil-koblingsfeltet 11 forsynt med skjerming på forsiden. De interne og eksterne kabler kobles til forsiden av tilkoblingsfeltet 10, hvorved kontaktforbindelsene har metallhylser. The module carrier is divided into two areas, one of which includes the connection area with connection field 10, mains connection area 11 and fuses for the module area 20. The module area 20 is shielded by means of a fold-out front wall 21 and all module carriers are shielded by means of a rear shielding cover 22, which covers and shields the module area 20, the connection field 10, the mains connection area 11 and the metallic connection plate 24. In addition, the connection field 10 and the mains connection field 11 are provided with shielding on the front. The internal and external cables are connected to the front of the connection field 10, whereby the contact connections have metal sleeves.
Sammen med sideveggen 23 danner frontveggen 21, den bakre skjermende tildekkingen 22 og skjermingen til tilkoblingsområdet et Faraday-bur. Derved er alle deler av modulene ledende forbundet med hverandre gjennom krympe-og trykksammenføyningsforbindelser. Together with the side wall 23, the front wall 21, the rear shielding cover 22 and the shielding of the connection area form a Faraday cage. Thereby, all parts of the modules are conductively connected to each other through crimp and pressure joining connections.
De tidligere nevnte taktmoduler som er ømfintlige for støyinnflytelse er anordnet i modulområdet 20. For å oppnå en ytterligere skjerming av disse, er skjermplater 30 anordnet som mellomvegger. Skjermplatene 30 er forsynt med kontakthakk 32, som rager ut av koblingsplaten 24. Låseskinner 31 er hengt på kontakthakkene 32, og de utgjør kontakten mellom skjermplaten 30 og koblingsplaten 24. Frontkontakten til skjermplaten 30 oppnås ved ikke viste kontaktfjærmatter, som er naglet til innsiden av den klappbare frontvegg 21. The previously mentioned clock modules which are sensitive to noise influence are arranged in the module area 20. In order to achieve further shielding of these, shield plates 30 are arranged as partitions. The screen plates 30 are provided with contact notches 32, which protrude from the connection plate 24. Lock rails 31 are hung on the contact notches 32, and they form the contact between the screen plate 30 and the connection plate 24. The front contact of the screen plate 30 is achieved by means of contact spring mats, not shown, which are riveted to the inside of the folding front wall 21.
