ABSTRACT:
An article such as an electrical connector (10) formed by molding a plastic septum (50) transversely across an axially extending cavity (22) through a metal shell (20) and about the array of contacts (60) extending axially within the axial shell cavity (22). The metal shell (20) includes a peripheral flange (34) around the inner surface (30) axially at the location (32) of the plastic septum (50), and upon curing and cooling the plastic septum includes portions of solid material axially to each side of the peripheral flange (34). The flange (34) has a dovetail cross-section having undercuts within which solid material of the plastic septum (50) is disposed forming a seal peripherally around the axial cavity (22). The contact sections (62) extending from the connector may then be subjected to a forming step to define right angles for example, with portions (66) of the contacts (60) embedded with the plastic septum (50) being of irregular cross-section to establish resistance to the stresses of such forming and maintain the sealed nature of the connector (10).
