ABSTRACT:
An electrical connector having a contact providing combined strain relief and insulation piercing for an elongated insulated conductor. A spring metal contact member is elongated in a longitudinal direction and has a contact end and a portion wrapped longitudinally back over itself to form first and second overlapping contact member portions. The overlapping contact member portions are formed therebetween with at least one insulation cutter and at least one strain relief clamp. The strain relief clamp is spaced from and on the opposite side of the cutter from the contact end. A nonconductive housing defines a chamber therein for receipt of at least a portion of the overlapping contact member portions. The chamber has opposing sides spaced so that upon positioning the overlapping contact member portions therebetween, while an insulated conductor is positioned between the cutter and the strain relief clamp, the overlapping contact member portions are forced from an open to a relatively closer closed position thereby causing the strain relief clamp to clamp an insulated portion of such insulated conductor and thereby causing the cutter to displace the insulation and to engage the conductor of such insulated conductor.
