Abstract

The disclosure relates to an electrical connector employed to make and break an electric motor main circuit between the control unit side and the side of the box-shaped frame of a control center. The electrical connector includes a male contact, a female contact having a pair of contact strips engaged with and disengaged from the male contact and a end section to which a connecting conductor is connected. A pair of conductive strips of the connecting conductor extends at the outside of the contact strips of the female contact in an opposite relation to the same. The conductive strips of the connecting conductor are coupled by a regulating rod which prevents the outward movement of the conductive strips. The female contact and the connecting conductor are integrated and enclosed in a cavity of an insulating case for oscillation. The contact pressure between the male and female contacts is increased by an electromagentic repulsive force induced between the contact strips of the female contact and the connecting conductor.

Claims1

Dependent claims

An electrical connector utilizing electromagnetic repulsive force to increase contact pressure between a male and female contact, comprising:

(a) a male contact;
(b) a female contact having a pair of extended contact strips, said female contact being provided for engagement and disengagement with said male contact;
(c) a connecting conductor connected to said female contact and having a pair of conductive strips extending in the general direction of the extended contact strips;
(d) an insulating case having a cavity for enclosing said female contact and said connecting conductor integrated therewith for oscillation therein;
and
(e) means for inducing an electromagnetic repulsive force between the contact strips of the female contact and the conductive strips of the connecting conductor, when current flows through the female contact and the connecting conductor, to increase contact pressure between the male contact and the contact strip of the female contact, the means including a regulating member engaging the pair of conductive strips of said connecting conductor so as to limit each of the conductive strips of said connecting conductor from being moved away from the male contact and so as to allow each of the conductive strips to be moved toward the male contact.
