Contact member 40 has first and second contact portions 42, 46, the first contact portion 42 being secured in the housing 56 and engagable with the at least one circuit path of the electrical connector to which the filtering device 38 is secured. Second contact portion 46 is exposed along a bottom surface 62 of aperture 60 and is paired with and spaced from third contact portion 50 which is also exposed along a bottom aperture surface 62. Fourth contact section 52, engagable with ground means is secured in housing 56 and extends outwardly from third contact section 50. Filter member 68 is electrically engaged to the pairs of second and third contact portions 42, 46. The invention is further directed to a coaxial connector having device 38 mounted thereon to provide filtering means between the connector and an isolated ground means.
