Definitions

  • the removable portion of the connector may be manually disconnected from the stationary portion thereof to serve the purpose of a load-break switch, or, vice versa, the removable portion joined with the stationary portion to serve the purpose of load make switch, but a serious hazard is involved when a disconnected removable'portion is reconnected with the stationary portion while a fault (such as an unexpected ground fault) exists somewhere on the load side of the connector.
  • the hazard is multiplied with each disconnection and reconnection of separable connector portions of the character currently conventional (up to kv.) which have the conductive member of the separable portion equipped with a follower made of arc suppressing, but substantially non-conductive, material.
  • the garter spring is accommodated in an exterior circumferential groove which may be produced by deforming the fingers so as to make an internally projecting circumferential ridge whose internal diameter is sufficiently less than the outside diameter of probe 9 that the fingers 34 will be wedged radially outward (against the tension of spring 35) when the probe 9 is inserted within them.
  • the inner periphery of the array of tungsten tipped extremities on the fingers 34 is preferably such that such extremities be out of contact with the probe 9 when the removable portion of the connector is fully seated in connecting position.
  • the resultant female receptor is positioned in the chamber of the half-liners shown in FIG.
  • any such are drawn between conductive probe 9 and receptor 29 is diverted from the areas which make contact under closed circuit conditions, and occurs between tip 10 and the tips of fingers 34; and is, as the separating action proceeds, subjected simultaneously to a plurality of arc-extinguishing influences, e.g., stretching, as the distance between tip 10 and tips of fingers 34 increases; pinching, as the successive pairs of clappers snap together behind the receding tip 10; rarefication of the atmosphere within capsule 12 (particularly if the separating action is fast enough, and the clearance between probe 9 and channel 21 small enough, that vacated space within the capsule 12 is increased at a greater rate than outside air can leak in between the outside of elastic probe 11 and elastic sheath 7, and then between probe 9 and channel 21); and evolution of arc-suppressing gases from the relatively large arc-accessible surface areas of the clappers 25, and the halfliners 13.
  • a plurality of arc-extinguishing influences e.g., stretching, as the distance between tip 10 and tips
