  • An additional object of this invention is to provide a compact, remotely operable relay of relatively large power handling capability which is enclosed in a vacuu-mized envelope.
  • FIG. 1 is a longitudinal sectional view of a preferred form of this invention
  • FIG. 2 is a cross sectional view taken generally in a plane indicated by lines 22 of FIG. 1;
  • FIG. 3 is a partial vertical sectional view taken in a plane indicated by lines 3-4, of FIG. 2 and showing the contacts and shorting bar only.
  • FIGS. l3 In general terms, one form of the invention chosen for illustration, and shown in FIGS. l3 comprises collinear, generally cylindrical fixed contacts 10, 11, shorting bar 12 for connecting and disconnecting said contacts, insulating rod 13 (FIG. 2) supporting shorting bar 12 at one end, armature 14 supporting the other end of rod 13 and supported by spring 15, coil 16 for magnetically attracting armature 14 and causing shorting bar 12 to connect contacts 1G, 11 and vacuumized envelope 17.
  • Envelope 17 may be formed by two cylindrical outer sections 4, of insulating material such as ceramic fixedly secured to a central cylindrical section 6 of brass or the like.
  • This central section may be provided with a pair of radially inwardly extending flanges 7, 8 at its opposite ends so as to receive the inner ends of ceramic sections 4, 5.
  • the surfaces of ceramic to be joined with flanges 7, 8 may be metallized in the conventional manner so that the three cylindrical pieces may be integrally secured together by brazing.
  • a smaller diameter metallic cylinder 21 Extending outwardly from the central section 6 is a smaller diameter metallic cylinder 21 which is closed at its remote end by a cap plate 2-2. Cylinder 21 is brazed at its inner end to central section 6 so as to provide a vacuum tight joint.
  • ceramic sections 4, 5 may be provided with closures 2-3, 24 respectively to which are secured the contacts 10, 11. Said closures are, of course, vacuum tight relative to the cylindrical sections and the contacts 10, 11.
  • the remote ends of contacts 10, 11 are provided with recesses 28, 29 respectively, for receiving the ends of cable conductors 30, 31.
  • a covering of epoxy cement 32 may be used between the ends of cylindrical sections 4 and 5 and cable insulation 33 to provide electrical insulation for the exposed portion of conductors 30, 31 and the remote ends of contacts 10, 11.
  • contacts 10, 11 are spaced apart and provided with slanted fiat contact surfaces 36, 37, respectively (FIG. 3).
  • Said contact surfaces 36, 37 are disposed at an angle of approximately 45 with respect to the plane normal to the axis of contacts 10, 1'1 and also face generally towards shorting bar 12 (FIG. 3).
  • Sh-orting bar 12 comprises a generally rectangular section copper or other suitable conducting material provided With slanting contact surfaces 38, 3-9 complementarily formed relative to surfaces 36, 37 respectively for engagement therewith. Contacts 10, 11 are also formed from copper or other suitable conducting material.

At its other end, rod 13 is mounted to one end of an armature 14- comprising a rectangular block of iron or other ferromagnetic material. The end of armature 14 opposite rod 13 is mounted .on a cantilever spring 15 which in turn is supported by end cap 22 so as to normally hold shorting bar 12 away from contacts 10, 11. Thus rod 13, armature 14 and spring 15 are enclosed within cylinder 21.
  • Electromagnet 16 is .mounted outside of but adjacent cylinder 21, and is positioned for pulling armature 14 in the direction which causes shorting bar 12 to engage contacts 10, 11 simultaneously when said coil is energized.
  • spring 15 causes shorting bar 12 to be disengaged from contacts 10, 1 1 simultaneously.
  • this device occupies only slightly more space than does a section of insulated cable, and also weighs less than conventional high voltage switching apparatus.
  • the invention is not restricted to the use of an electromagnet to move shorting bar 12.
  • Other conventional arrangements such as a bellows actuated insulated rod and shorting bar may be used in place of coil 16 and armature 14.
  • Vapor condensing surfaces such as annular ridges 42 on contacts 10, 11 may be provided to minimize the deposit of conductive materials on the ceramic sections.
