Connectors embodying the invention include a metallic shell having an inner wall for securely holding a glass preform within the inner wall of the metallic shell. The preform has generally parallel top and bottom surfaces with a number of predetermined contact pin holes extending between the top and bottom surfaces. Hollow tubular sleeves for securing and supporting contact pins are positioned within selected ones of the contact pin holes; each tubular sleeve having a bottom end embedded in the preform and a top end extending above the top surface of the preform. Contact pins of conductive material are securely positioned within the tubular sleeves; each contact pin having a top end extending above the top end of its associated tubular sleeve and a bottom end extending below the bottom surface of the preform. Conductive wires may be connected to the top ends of the contact pins, with each tubular sleeve providing support for its associated contact pin and the corresponding wire connection. Then, insulating shrink tubing, extending from the top surface of the preform, may be placed over each tubular sleeve, its corresponding contact pin and a portion of the associated wire including the wire connection to the contact pin. The wire and its interconnection to a contact pin may be examined before and after the application of the shrink tubing.
