TELECOMMUNICATIONS SIGNAL COUPLER APPARATUS AND METHOD

摘要

The present invention provides a mains power line signal coupler circuit comprising a mains connection section, a coupling section, and a data connection section wherein the data connection section comprises transient suppression means arranged to suppress transients originating from the mains connection section. The present invention also provides an improved signal coupler housing and method of installation. The coupler housing is characterised by the fact that it is separable in two parts, the first part (509) comprises the main power supply connectors (300, 301) and the cables clamping means (503, 503A); the second part (401) comprises the coupler section (402) and the data connector (206). The second part can be replaced with a blanking cover (not shown) and allows a later installation of the signal coupler part.
