Abstract: A filtered terminal block assembly comprises a dielectric insert (20) having a cavity (48) including a pocket (50) and a bore (52), a ground plate (16) to which the dielectric insert (20) is disposed and having an opening (46) in alignment with the bore (52), a filter element (24, 26) having an inner end disposed in the cavity (48), an electrical contact (14) extending through the filter element (24, 26), the pocket (50) and the bore (52) with an outer end of the filter element (24, 26) electrically connected to the electrical contact (14), a ground member (22) electrically connected between the filter element (24, 26) and the ground plate (16), and an electrically-conductive thixotropic material (54) in the pocket (50) and along an inner surface of the cavity (48) electrically connecting an inner end of the filter element (24, 26) to the electrical contact (14).
