Abstract
Line power voltage is taken from a cable system tap module by a device having a housing, first and second electrical insulators coaxially positioned within first and second cavities in the housing, a contact tip member positioned in the first insulator and having a tip end portion extending through an opening in an end of the housing, and a hollow screw employed as a seizure screw in the tap module. The hollow screw has a hollow with a contact socket positioned therein for resiliently receiving the tip end portion of the contact tip member so as to provide a longitudinally sliding electrical connection between the contact tip member and the hollow screw. An inductance coil is positioned within an axial bore of the second insulator. The external dimensions of the first and second insulators correspond to the dimensions of the first and second cavities so that the inductance coil and the contact tip member are accurately positioned within the housing. A power take-off cable has a first lead connected to the housing, and a second lead connected through a high frequency filter to the contact tip member. The external surface of the housing provides a gripping surface.
