Definitions

  • the invention relates to a vacuum switch according to the preamble of the claim 1.
  • the Vacuum switch according to US-A 3 997 747 Actuating rod from a non-circular (preferably corrugated) sleeve made of a highly conductive Surround material, the inside of the outside the operating rod along one or touched several of their surface lines.
  • This sleeve is in turn from one coaxial to the operating rod arranged, fixed tube surround, that is firmly connected to one connector.
  • compressible Rods for example made of rubber, who strive to deform the out-of-round sleeve and thus in contact with both the pipe and also hold with the operating rod.
  • This Design probably ensures good contact between operating rod and switch connection with low friction, but is with very great design effort and cannot benefit from that for vacuum switches characteristic short switching strokes to draw.
  • a vacuum switch that has the features in the preamble of Has claim 1 is in DE-U1-78 35 159 disclosed.
  • the connection has a fixed, perpendicular to the contact operating rod, as Round conductor trained busbar on which a T-shaped contact connector with a spring built-in slat contact rotates.
  • On against the Actuating rod protruding projection of the contact connector are two, forming a double knife Metal strips through a screw or plug connection attached at one end. At the other end, the metal strips grip on the actuating rod on opposite one another Pages under the action of a spring clip, which by a Radial bore of the actuating rod is guided and with its ends in depressions on the outside of the Metal strip is fixed in position.
  • JP-A-50018 describes a connection arrangement with Metal strip between one on the moving contact piece arranged connector and a fixed outer Connection piece in connection with a vacuum switch.
  • the ends of the metal strips are each marked by a Bolts on the fixed connector or on the movable Connection piece held.
  • the metal strips are by springs arranged on the bolts to the respective Connection pieces pressed on.
  • the proposed vacuum switch in the characterizing part of the claim 1 specified characteristics.
  • FIG. 1 and 2 are parts of a vacuum switch 10 shown.
  • This has a vacuum vessel 11, in which both a fixed and a movable contact piece (both not shown) are accommodated.
  • the movable contact piece is with an electrically conductive operating rod 12 connected, the sealing, however slidably guided out of the vacuum vessel 11 is.
  • the operating rod 12 On her removed from the vacuum vessel End is the operating rod 12 with provided with an eyelet 13 on which a not shown Switch actuator is connected to the Actuating rod 12 (and thus the movable Contact piece) of that shown in solid lines in Fig. 1 Einschalt- shown in dashed lines Switch-off position (and vice versa) around the stroke 14 to move.
  • the one assigned to the actuating rod 12 Fixed connection 15 of the vacuum switch 11 here has the shape of a solid, in cross section E-shaped profile.
  • a the operating rod 12 surrounding housing 16 is over a Isolator 17 with the switch drive, not shown connected.
  • the electrical connection between the operating rod 12 and the connector 15 is from perceived a rocker 18, the structure is described below.
  • the rocker 18 points two elongated, exactly the same profile, however metal strips arranged in mirror image 19, 20, for example made of copper or from a Copper alloy, on which one essentially have a rectangular cross section.
  • the one another opposite end portions 21, 23 and 22, 24 of the metal strips 19 and 20 diverge from each other so that the ends of the rocker 18 appear forked.
  • These end sections are shaped to have a cylindrical section 25 the actuating rod on the one hand or the middle leg 26 of the connection 15 each frictionally at opposite points and springy like a pair of tweezers or touch pliers.
  • the metal strips 19, 20 are in the center of one Penetrates sleeve 27 through which a threaded bolt 28 with screwed nut 29 leads. Between one resting on the head of the threaded bolt 28 Washer 30 and the metal strip 18, a compression spring 31 is supported, the the metal strips 19, 20 are biased towards one another, but with a spacer between them 32 be made of an insulating material can, that ensures that the two metal strips 18, 19 in their middle sections can't touch.
  • the compression spring 31 ensures that the end portions 21, 23 and 22, 24 of the metal strips 19, 20 with sufficient contact pressure Touch section 25 or the middle leg 26. It should also be noted that if the two metal strips 19, 20 have a high Conduct electricity, this contact pressure another Experiencing increase because of the metal strips 19, 20 because of the magnetic field resulting from the current attract each other.
  • FIGS. 1 and 2 differs from that of FIGS. 1 and 2 essentially in that of engaging with the end sections 22, 24 of the metal strips 19, 20 not certain part of the connection 15 has the shape of a rib, but the shape of a cylindrical stub, the axis of which is rectangular to the axis of the actuating rod 12 stands.
