Abstract
An apparatus and method of molding a biconical socket (FIG. 1) of precise concentricity and length. The biconical socket is formed by a two piece mandrel assembly (20, 21), each mandrel member having a frustoconical end (22, 23). The frustoconical ends of the mandrel members are abutted and aligned by means of a coaxially extending pin (24) in one member which engages a hole (25) in the second member. The pin is fabricated from a dissimilar material so that at the elevated molding temperature the clearance between pin and hole is substantially reduced, thereby providing precise concentricity. During molding the pressure of the mold material forces the mandrel members slightly apart against predetermined stops (32, 33) to provide a socket of precise length (L). The resulting biconical socket is particularly well-suited for use in an optical connector assembly.
