Signal connection device for a power line telecommunication system

A signal connection installation including a signal connection device and a fuse holder for making a communication signal connection to a mains electricity supply, the signal connection device being secured to the fuse holder, said fuse holder including an insulating body housing a power fuse of the mains supply, said insulating body having an aperture at one end with a radially projecting raised formation, wherein said signal connection device includes:

• a head portion having an axial aperture and a retaining clip cooperating with said radially projecting raised formation of said insulating body for the attachment of said head portion to said fuse holder;
• a communication signal connection connected to a conductive component, said conductive component consisting of a signal fuse, said signal fuse projecting axially from said aperture in said head portion so as to make electrical contact with said power fuse through said aperture in said insulating body of said fuse holder;
• and
• a signal path interconnecting the signal fuse and the communication signal connection, the signal path including a filter which presents a low impedance to communication signals and a high impedance to mains electricity.

• a communication signal connection connected to a conductive component, said conductive component consisting of a cartridge type signal fuse, said signal fuse being slidably held in said aperture in said head portion and projecting axially therefrom so as to make electrical contact with said power fuse through said aperture in said insulating body of said fuse holder, said signal fuse being urged in the direction of said power fuse by a spring located within said aperture in said head portion;
• and
• a signal path interconnecting the signal fuse and the communication signal connection, the signal path including a filter which presents a low impedance to communication signals and a high impedance to mains electricity.
