A hermetic terminal comprising: a cup-shaped body including a bottom wall and a peripheral side wall, the bottom wall having an interior surface and an exterior surface and a plurality of first openings therein; a plurality of current-conducting pins, one current-conducting pin extending through each first opening, the pins sealed within the first openings and electrically isolated from the body; and a dielectric pin-isolating feature attached to the body and extending in a first direction parallel to a longitudinal axis of the pins and terminating in the first direction beyond the outer ends of the pins and in a second direction perpendicular to the longitudinal axis of the pins and terminating in the second direction near the peripheral side wall; wherein the dielectric pin-isolating feature separates adjacent current-conducting pins such that the dielectric pin-isolating feature obstructs a direct, linear, through-air path between adjacent current-conducting pins, characterized in that: the pin-isolating feature is attached to the exterior surface of the bottom wall of the body and comprises a lower base portion integrally formed with an upper barrier portion, the base portion sized and shaped to closely fit a perimeter of the exterior surface of the bottom wall, and the upper barrier portion comprising a plurality of vertically-upstanding, planar ribs; the base portion comprises an underside surface that is adjacent to at least a portion of the exterior surface so as to create a cavity between the base portion and the exterior surface and a central portion comprising a cylindrical member having a passageway extending therethrough to the underside surface; wherein a dielectric injection molding material occupies the cavity and the passageway and forms an enlarged retaining head located outside of the passageway and against the cylindrical member. a cup-shaped body including a bottom wall and a peripheral side wall, the bottom wall having an interior surface and an exterior surface and a plurality of first openings therein; a plurality of current-conducting pins, one current-conducting pin extending through each first opening, the pins sealed within the first openings and electrically isolated from the body; and a dielectric pin-isolating feature attached to the body and extending in a first direction parallel to a longitudinal axis of the pins and terminating in the first direction beyond the outer ends of the pins and in a second direction perpendicular to the longitudinal axis of the pins and terminating in the second direction near the peripheral side wall; the pin-isolating feature is attached to the exterior surface of the bottom wall of the body and comprises a lower base portion integrally formed with an upper barrier portion, the base portion sized and shaped to closely fit a perimeter of the exterior surface of the bottom wall, and the upper barrier portion comprising a plurality of vertically-upstanding, planar ribs; the base portion comprises an underside surface that is adjacent to at least a portion of the exterior surface so as to create a cavity between the base portion and the exterior surface and a central portion comprising a cylindrical member having a passageway extending therethrough to the underside surface; wherein a dielectric injection molding material occupies the cavity and the passageway and forms an enlarged retaining head located outside of the passageway and against the cylindrical member.
