Shielded electrical connector with contact shunting arrangement

摘要

A shielded electrical connector comprises an insulating terminal housing formed of a base member and a cover member. The housing has a front mating face, a rear wire-connecting face and a terminal supporting platform extending between the two faces. Four electrical terminals are mounted on the terminal supporting platform with contact portions disposed in the area of the mating face and wire-connecting portions disposed in the area of the wire-connecting face. Each contact portion includes a resilient contact tongue spaced from the platform and having a free end extending away from the mating face. Each contact tongue is matable against a corresponding contact tongue of the complementary connector to urge the contact tongues toward the respective platforms from which they are supported. An electrical shunting device is fixedly mounted in the housing and disposed adjacent to the contact tongues in the area of the free ends thereof. The shunting device engages preselected contact tongues when the connector is in an unmated condition and is spaced from the contact tongues when the connector is in a mated condition. The shunting device comprises an insulative, substantially planar surface having four conductive contact pads arranged thereon facing the terminals. Each contact pad is oriented adjacent a respective one of the contact tongues such that contact between each pad and its respective, adjacent contact tongue is made in substantially the same relative position on all contact tongues.
