Definitions

  • the invention relates to a ring-shaped electric contact device for cooperation with an axially movable countercontact surrounded by said contact-device, e.g. a counter contact of an electric switch having switching elements adapted to be inserted into and removed from the stationary part of said switch, when the stationary conductors thereof are under tension.
  • the invention has the object to simplify the construcv tion of such a ring-shaped contact device and to make it cheap, however, without affecting the reliability thereof.
  • the contact device comprises, in combination, a tube of insulating material, a hole provided in the wall of said tube, a circularly curved metal contact strip closely contacting the inner surface of said tube and having outward bent end portions passed through said hole and a metal terminal member connected to said end portions of the strip loutside the cylindric space surrounded by said strip.
  • This contact ring is held against axial movement relative to the insulating tube by means of the end portions of the contact strip penetrating into the hole of the wallof said tube and by means of the terminal member and/or the connecting parts thereof.
  • the end portions of the contact strip may be bent round a clamping block inserted in the hole of the wall of the insulating tube and firmly held between said block and the terminal member connected to the latter.
  • the end portions of the contact strip may also be firmly held between the bevelled walls of a recess in the side of the terminal member facing the inner space of said tube, said member penetrating into the hole of the wall of said tube, on one side and at least one nutbolt having a fiat conical head passed through a hole of said terminal member on the other side.
  • Fig. 1 a sectional elevational view of a portion of Ian electric switch provided with a strip-shaped contact-ring according to the invention
  • Fig 2 a plan view of a part of a contact-ring used in the switch shown in Fig. 1, and
  • Fig. 3 a variant of the contact-ring illustrated in Fig. 2.
  • FIG. 1 designates a tube of insulating material.
  • a metal contact strip 2 of which the end portions are passed through a hole 3 in the wall of the tube.
  • the end portions of said contact strip are bent round a flat metal clamping block 4 inserted in the hole 3 and said end portions are held firmly between said block and an angular terminal member 6 connected to said block 4 by means of screws 5.
  • a high-voltage polyphase circuit-breaker of the draw-out type in combination, for each phase a fixed first tubular member made of insulating material, a second tubular member constructed of insulating material disposed concentric with the first member and removable axially therein at will for insertion into operative position axially of the firstv tubular member and withdrawable therefrom, a first fixed contact disposed internally of the first tubular member extending circumferentially against the inner surface of the tubular member and axially of the first tubular member a distance less than the axial length of the first tubular member, a second fixed contact mounted on said second tubular member having contact surfaces extending radially outwardly for slidably engaging the first contact and positioned to make electrical contact with the first contact when the second tubular member is inserted in operative position axially of the first tubular member, said second contact having resilient annular contact surfaces disposed internally of the second member, a third fixed contact disposed axially in said second tubular member axially spaced from the
