Abstract
A rear cover for use in waterproof connectors and a process for forming a resilient sealing member molded in one piece in the rear cover are provided. The rear cover, in which an electric wire is inserted through a base wall, has a hollow holder pattern on an outer surface of the base wall and a molded-in resilient sealing member containing: a holder formed in the holder pattern; a sealing body extended from the holder, which protrudes toward an inner side of the base wall and has a through hole for the electric wire to pass therethrough; and a plurality of sealing lips formed around the through hole, wherein a portion of periphery of the holder pattern is notched to form a hollow of injection inlet for molding the resilient sealing member in one piece in the rear cover. Thus, the rear cover according to the present invention improves a property of mold releasing and maintenance of a mold. That is, a deformation and damage of the rear cover can be prevented, in addition, an action responding to wear of the mold is easily executed and a fin formation can be prevented.
