Abstract: A receptacle for an electrical connector which comprises an elongated insulative housing having parallel lateral walls, parallel end walls and base wall. An interior cavity is formed by those walls, and a longitudinal groove extends between the longitudinal walls from adjacent one of said end walls to the other end wall. At least one conductive contact having a base end and a distal end extends upwardly through the base wall and then in the interior cavity. A wafer having a hardness greater than the base wall is positioned beneath the base wall to enhance dimensional stability of the receptacle in a vertical or other direction perpendicular to the substrate on which the receptacle is mounted.

Abstract: A filter connector has a ferrite barrel with a rectangular bore therethrough. The configuration of the bore closely matches the substantially rectangular cross sectional configuration of an electrical connector received within the bore. The connector has a pair of wings upstanding from a base thereof. A single gate or a cooperating pair of gates is(are) attached to one or both of the wings. When folded the gate(s) close the bore through the barrel.
