Abstract:
1. An electrical connector comprising: a male contact; a female contact configured to couple with the male contact; and a female contact housing having an internal cavity within which the female contact is contained, and further having a passage that extends from an outer end of the cavity to an exterior surface defined by the housing; wherein the female contact has an open outer end portion located toward an outer end of the cavity adjacent the passage and configured to receive the male contact, wherein the male contact is movable inwardly through the passage for engagement with the open outer end portion of the female contact and is movable outwardly through the passage upon disengagement with the open outer end of the female contact; and wherein the passage has a cross-section defining an area configured similarly to and slightly larger than a cross section defined by the male contact to define a constriction within the passage when the male contact is present within the passage wherein in the event an electrical arc is created by disengagement of the male contact with the open outer end of the female contact, air contained within the internal cavity is heated by the electrical arc and creates pressure within the internal cavity that forces air outwardly through the constriction in the passage to extinguish the electrical arc.
