Definitions

  • the invention is an improvement upon the vacuum relay shown in the copending patent application Serial No. 204,441, filed April 26, 1938.
  • the relay there described has its armature and contacts fixed on a carrier made of an insulating material.
  • a ceramic material is to serve this purpose.
  • this carrier is in the shape of a bar suspended at one of its ends after the manner of a pendulum. The free end thereof, that is, the end remote from the point of suspension r fulcrum, is provided with the relay contacts.
  • This construction aims to afford an insulating path for high voltages which is of the greatest possible length.
  • Such construction is possessed of the disadvantage that the carrier or bar so suspended is very sensitive to shocks whereby undesired switching operations readily occur.
  • the invention therefore proposes to fasten the bar-shaped carrier to a bridge-shaped device in a manner to locate the fulcrum in the vicinity of the relay contacts.
  • FIG. 1 is a sectional view of one embodiment of the invention, while Fig. 2 shOWS a section thereof on line 2-2.
  • Bar 9 is rigidly connected with the cross-bar of a U-shaped member 2
  • This member is fastened to a support 6 by a piece of sheet metal 8 and is centered in the bulb 2 by suitable clamping means, such as a mica disc [9.
  • Bar 9 has ribs 20 arranged to add to the length of the insulating path.
  • metal plates I0 attached to the bar 9 are acted upon by a magnetic field produced by electromagnets external to the tube (not shown).
  • the plates are moved in either of two directions depending on the polarity or energization of the electromagnets, and the bar 9 is pulled or pushed closing the contacts carried by contact member II on either of the springs I4 or 15.
  • Leads from the high voltage circuit it is desired to make operative are attached to the springs I4 and I5, and the armature II, and the high voltage circuit is therefore made operative when the armature is moved a distance suflicient to close the contacts of member ll against springs M r I 5.
  • the armature may, however, be actuated by any of several known means.
  • an armature and cooperat ing switching contacts In a vacuum relay, an armature and cooperat ing switching contacts, a support of insulating material for said armature and contacts, a U- shaped movable clamp having a crossbar to which said support is attached, studs projecting from the free legs of said U-shaped clamp, and a stationary clamp in which said movable clamp is pivoted by means of said studs.
