Abstract: There is disclosed a ground pin blade having an improved design having a vastly enhanced resistance to fatigue failure. There is also disclosed a molded electrical connector plug utilizing the ground pin blade. The ground pin blade is a channel-shaped member having the sidewalls of its end which is embedded in the molded plug body flared outwardly from a channel shape to an included side wall angle of about 90 degrees. The channel member has an aperture in its bottom wall adjacent the transition between the flared and unflared portion and this aperture receives the electrical conductor for the ground conductor of the electrical cord. The ground pin blade is intended primarily for use in a molded-on, electrical plug useful in life support equipment and, for this purpose, a plurality of strain relief members are used to firmly secure the assembly of the molded plug and electrical conductors.

Abstract: There is disclosed an electrical cord and attachment plug assembly suitable for use in applications requiring a very high degree of reliability, e.g., for use on hospital and life support equipment and the like. The assembly is of a construction which insures that the electrical cord, or any of the single conductors thereof, does not pull out of the plug assembly and interrupt the electrical continuity. The assembly includes an electrical cord having a plurality of single conductors within an outer jacket and bearing a plurality of contact members, including a pair of flat-bladed prongs connected distally to respective ones of a pair of the single conductors with each of the single conductors knotted adjacent the contact members. The cord also bears cord-retaining bushings clamped about the jacket of the cord.
