Abstract An improved shielding assembly for an overmolded electrical connector is formed by a pair of mating metal shell members which engage a peripheral metal housing of a standard connector and enclose the rear conductor exiting portion thereof. The shell members each include embossed strengthening means as well as interengaging side walls to completely enclose the rear of an electrical connector. The shell members are each further provided with overmolding pressure release means which opens at a predetermined pressure and allows a limited amount of overmolding material to enter the shell members while equalizing the inner and outer shell member pressures. The shell members also include gripping apertures which allow overmolding material to enter and harden thereby becoming fixedly attached to the shell members to prevent withdrawal due to shrinking as the overmold material cools. At least one of the shell members is preferably provided with continuity tines which positively engage the metal housing of the connector to assure good electrical contact therewith. The shell members can also include an interdigitating profile which assures proper relative positioning of the shell members.
A shielded electrical connector assembly of the type comprising an insulative housing having a front mating face and a rear conductor receiving face, a plurality of terminals in said housing, and stamped and formed metal shell means enclosing the rear conductor receiving face of the housing and a cavity extending rearward therefrom, the connector being characterized by at least one pressure relief vent stamped and formed in the shell means, each vent comprising an aperture sheared completely through the shell means about only a portion of its periphery, the blank stamped therefrom remaining hinged to the surrounding shell means, the aperture remaining closed by the blank unless excessive exterior pressure during an overmolding operation is relieved by inward movement of the blank.
