Definitions

  • the transient suppression means comprises a voltage clamping diode within a diode bridge.
  • Figure 1 e shows a typical installation point of a signal coupler unit in accordance with Figure 1 ;
  • the mains connection section comprises three low-voltage (for example 240V, 50Hz) power supply connectors (100, 105, 106), a fuse (101), and a switch (104).
  • the live (or "phase") mains connector (100) is connected in series via the fuse (101), and the data coupling unit (103) to the neutral mains connector (105).
  • the mains live connection is connected via a capacitor (1 10) and the primary windings of a transformer (1 1 1 ) to the mains neutral or protective earth connection.
  • the transient suppression unit (107) comprises a bridge comprising four diodes (120) and a voltage clamping diode (121 ) as shown in Figure 1c.
  • Alternative embodiments include, but are not limited to, either a gas discharge tube or a diode bridge with a metal oxide varistor.
  • the signal coupler unit comprises two separable parts: a mains connector part (A) and a signal coupler part (B).
  • the signal coupler part (B) houses the signal coupler circuit, such as that described above, that provides the electrical isolation between the RF signal and the mains supply.
  • the housing part also comprises means to locate the base cover plate (403) to the housing (401 ).
  • this comprises pegs (706) integral to the housing moulding and arranged to be located through corresponding apertures in the base cover plate (403); the ends of the pegs may then be welded to the base cover plate to fix the base cover plate in place. Attachment in this way is both cheaper than alternative screw fixings and improves electrical safety by avoiding a introduction of an unnecessary electrical path between the mains connector part (A) and the signal coupler part (B).
  • Those parts of the housing adjacent the mains connection preferably withstand the temperature of arcing parts nearby up to a temperature of, for example, 135 °C, so as to meet regulatory requirements.
  • the thickness of plastic parts, and creepages and clearance distances between mains connected parts and accessible parts are sufficient to provide Reinforced Insulation to meet national regulatory requirements.
  • the RF signal to be injected onto the mains supply, and the RF signal from the mains supply is assumed to have an amplitude of 5 V AC rms and have a fundamental frequency in the range 2MHz to 6 MHz.
  • a fuse having a short circuit rupture capability to BS 88 is fitted in series with the live connection between the Mains Connection Part of the Power Tap and the RF Coupling Part. This fuse is located as close as possible to the incoming live terminal.
  • a bi-directional voltage breakdown circuit is fitted in the secondary circuit. This protects against transient voltages that appear between across the output of the transformer (differential mode).
  • the circuit must have a low enough capacitance in its "Off" condition to present negligible loss to the RF data signal.

Abstract

La présente invention porte sur un circuit de coupleur de signaux de ligne d'alimentation électrique qui comprend une section de connexion sur secteur, une section de couplage et une section de connexion de données, cette dernière comprenant un organe limiteur de surtension agencé de façon à supprimer les phénomènes transitoires provenant de la section de connexion sur secteur. La présente invention porte également sur un boîtier amélioré de coupleur de signaux et sur son procédé d'installation. Ce boîtier se caractérise en ce qu'il peut se séparer en deux parties: la première partie (509) comprenant les connecteurs (300, 301) de l'alimentation sur secteur et les dispositifs de serrage (503, 503A) des câbles; la seconde partie (401) comprenant la section coupleur (402) et le connecteur (206) de données. Cette seconde partie peut être remplacée par un couvercle de suppression et permet l'installation ultérieure de la partie coupleur de signaux.
