摘要：A sealed electrically conductive connection for a hanger to an insulated spine of an electroplating rack. The rack is coated with a plastisol material which prior to curing in an electroplating bath is flexible and which hardens in use. The connection comprises a plastic connector which has a conical end portion which extends into an annular aperture in the plastisol material and stretches it to obtain a sphincteral embrace thereby and bulge the material to obtain a thick section which resists hardening throughout, and thus maintains its elasticity and seal. A counter-sunk portion in the spine mates with a metalic connecting stud to obtain a good contact and the connector has a bore to tightly admit a hook shank.
