Female contact, particularly for high voltage breaker

Abstract From the Canadian patent

Female contact, e.g. for use in high-voltage disconnectors that comprises two interpenetrated sockets. The first metal socket is made of a single extruded piece of metal which has been machined; it comprises metal contact fingers (2) designed to cooperate electrically with a male contact (8). The other socket comprises fingers (11) made out of an insulating material; the insulating fingers (11) limit any radial and lateral movement by the contact fingers to predetermined values below their elastic deformation limit and insulate the contact fingers from each other and from the eventual compression ring that will surround the contact fingers in order to eliminate the risk of fingers welding …
