ABSTRACT OF THE DISCLOSURE This invention relates to a female electrical contact for use as an electrical connector or as one contact of a multi-contact electrical connector. Prior art female contacts are generally configured in a U-shape with the arms of the U extending in a direction axially of the contact and bent toward one another for receiving a mating male contact pin. Occasion- ally, the male contact pin may be incorrectly inserted so as to push one of the contact leaves away from the axis of the contact, and give rise to a faulty contact. If the elastic limit thereof is exceeded, the contact becomes useless. According to the invention, there is provided a single- piece female electrical contact formed from a single piece of sheet metal and which includes a pair of opposed contact leaves enclosed in the end of a tubular member of rectangular cross section. The tubular member has a closed end with a small aperture at its center opening into between the two opposing contact leaves. The base for the contact leaves is U-shaped and has a pair of tabs which are bent to retain one of the rectangular faces of the tubular member in firm fixed position. The closed end may be concave to provide a camming action for the male pin to be inserted in the aperture therein. Additionally, a terminal strip portion can be provided extending from the U-shaped face to provide connection for an external conductor.
