Abstract
A dual molded connector and a dual molding process for fabricating a insulative housing having a relatively rigid portion and a relatively more flexible sealing portion is disclosed. The relatively rigid portion is first formed in a mold. Elastomeric material can then be injected after shifting portions of the mold define voids adjacent opposite faces of the molded rigid housing. An internal gate between opposite surfaces of the housing permits sealing material to flow into the void on opposite faces of the housing. Thus, only an external single gate for the injection of sealing material is necessary.
