Abstract

L'invention concerne un dispositif de distribution de signal radiofréquence depuis un câble d'entrée venant d'une antenne satellite ou terrestre, préamplifiée ou non, vers plusieurs sorties(S1-S7) coaxiales ou RJ45. Ce dispositif comprend un boîtier d'entrée(1,1',3), pouvant être chaîné sans câble avec un ou plusieurs boîtiers avals, identiques ou différents. Aucun des boîtiers ne contient d'alimentation secteur. Le boîtier d'entrée reçoit une très basse tension continue(110) par un bloc d'alimentation externe(10). Il l'injecte dans le connecteur d'entrée(E1) par un circuit d'injection(12) protégeant les sorties de cette tension d'alimentation, tout en transmettant au connecteur d'entrée les tensions continues de commande pouvant arriver depuis lesdites sorties. Plusieurs boîtiers Dans une première version, l'entrée(E1) latérale d'un boîtier(1) est directement connectable à une sortie(S3) latérale d'un boîtier identique. Dans une deuxième version, le boîtier d'entrée(3) amplifie le signal à distribuer. L'ensemble est compact, et facilement logeable sur le rail DIN d'un coffret télécoms, avec ses sorties d'un même côté. Figure: Fig.9The invention relates to a device for distributing a radiofrequency signal from an input cable coming from a satellite or terrestrial antenna, preamplified or not, to several coaxial or RJ45 outputs (S1-S7). This device comprises an input box (1,1 ', 3), which can be chained without cable with one or more downstream boxes, identical or different. None of the enclosures contain AC power. The input box receives a DC extra low voltage (110) from an external power supply (10). It injects it into the input connector (E1) via an injection circuit (12) protecting the outputs of this supply voltage, while transmitting to the input connector the direct control voltages that can arrive from said outputs. . Several boxes In a first version, the side input (E1) of a box (1) is directly connectable to a side output (S3) of an identical box. In a second version, the input box (3) amplifies the signal to be distributed. The assembly is compact, and easily housed on the DIN rail of a telecoms cabinet, with its outputs on the same side. Figure: Fig. 9
