ABSTRACT OF THE DISCLOSURE This invention relates to electrical connector of the insulatlon-piercing type. When dealing with stranded conductors, oftentimes the strands snag upon, and even become severed by, the edges which are provided for piercing the insulation of an insulated conductor. The present invention provides an improved electrical connector provided with a plurality of contacts, each of the contacts having an insulation-opening terminal element of sheet metal construction to electrically contact an insulated conductor. The contact is advan- tageously constructed for receiving an insulated stranded conductor, but is equally applicable for receiving an insulated solid conductor. Each contact includes an active portion, of either male or female configuration, a terminal element portion, and an intermediate portion connecting the active and terminal element portions. The terminal element portion preferably includes an elongate open channel of U-shaped cross-sectional configuration having side and bottom walls, the sidewalls including opposite portions dimpled in to provide inner detents forming, and separated by, a conductor-receiving notch for opening the insulation of the conductor and electrically engaging the underlying exposed con- ductor. A plurality of different embodiments of a detent are offered, each of which advantageously includes an enlarged wiping surface, a notch entrance and a smooth portion adjacent the notch entrance to prevent snagging, and possibly severing, of the individual strands of a stranded conductor.
