Definitions

  • the present invention relates to a magnetically controlled shielded tube contact relay, having spring contacts made of a soft magnetic material which can be magnetically excited so that reciprocal magnetic poles form at the opposite ends of each contact. Magnetic excitation is effected by a field generated by a coil surrounding the tube.
  • Relays of the type to which the present invention relates, are of increasing significance in the telecommunications switching art. Because of the frequency with which these devices are now used it is of importance to develop a serviceable relay design which can be manufactured at minimum cost.
  • An object of the present invention is to provide a magnetically controlled contact relay, of the type described above, that is of simple yet rugged construction.
  • Another object of the present invention is to design a relay which can at once include a plurality of contact pairs enclosed in the bulb of a conventional electronic tube.
  • the support is preferably made of a ceramic material and the metal strips applied by means of the screenprinting technique.
  • the metal strips are subsequently bonded into the support in the conventional manner by heating.
  • the fixed and movable contacts may then be hard-soldered to the metal strips, the solder being also preferably applied by the screen-printing technique.
  • the metal strips can thus be used both as a solderable layer for fastening the contacts and as electric conductors for connecting the contacts, ultimately, to the tube pins.
  • the support is preferably formed as a U-shaped piece.
  • the entire assembly is soldered in one operation in a single charge of a protective gas furnace.
  • the relay can also be constructed as a polarized relay by soldering a pair of fixed contacts to one arm of the support for each movable contact soldered to the other arm. These pairs then cooperate with their respective movable contacts to form individual contact units or switches. A permanent magnet is arranged between each pair of fixed contacts to provide the desired polarization.
  • FIG. 1 is an elevational view with the tube broken away to show the internal or contact portion of a shielded tube polarized relay according to one embodiment of the present invention.
  • FIG. 2 is an elevational view similar to FIG. 1 showing the internal or contact portion of the relay of FIG. 1, at right angles to the view of FIG. 1.
  • FIG. 3 is an elevational view of another embodiment of the invention where the support has another form.
  • FIG. 4 is an elevational view similar to FIG. 3 showing another fastening of the permanent magnet.
  • FIGS. 1 and 2 illustrate, in two elevational views, the polarized relay embodiment of the present invention.
  • the view of FIG. 2 is perpendicular to the view of FIG. 1; more particularly, FIG. 2 shows the left side of the relay illustrated in FIG. 1.
  • This embodiment of the present invention includes a U-shaped ceramic member 2, the two sides of which are lined with metal strips.
  • the metal strips thus serve, on one hand, as solderable surfaces for soldering or fastening the spring contacts 3a, 3b, 3c and 3d to the top arm of the U-shaped member and, on the other, as electrically conductive paths be tween the spring contacts and the tube pins.
  • the contacts 5a, 5b, 5c and 5d which oppose spring contacts 3a, 3b, 3c and 3d, respectively, are soldered to the other arm of the U-shaped member 2 on corresponding metal strips. Since this embodiment concerns a polarized switching relay, four additional opposing contacts 9a, 9b, 9c and 9d are soldered to the back of the lower arm, of which only the contact 9a is shown in the drawing, FIG. 2. All eight of these opposing contacts are also connected to respective tube pins that project through the tube base 12.
  • these springs may 'be interconnected by a connecting member 4 made of insulating material.
  • FIG. 2 there is shown the left-hand spring contact 3a, which cooperates with the fixed opposing contacts 5a and 9a.
  • a permanent magnet 6 is inserted into the space between these opposing contacts to prepolarize the relay.
  • the polarization 'of this magnet is shown in FIG. 2. 'by the arrows N and S.
  • the tube 1 is preferably either evacuated or filled with a protective gas.
  • FIGS. 3 and 4 illustrate another embodiment of the present invention, relating to a polarized relay.
  • This embodiment includes a ceramic member 15 of rectangular cross section, two sides of which are lined with metal strips 16 and 19.
  • the strips 16 connect the spring contacts 17, via appropriate connecting lugs 20, with the contact pins 21.
  • the strips 19 on the opposite side of the ceramic member 15 connect the spring contacts 18 with their respective tube pins.
  • To .get a polarized relay second spring contacts 22 are fastened on a second ceramic member 24, the sides of which are also lined with metal strips 25 and '26.
  • the permanent magnet 23 is inserted into the space between the opposing contacts 18 and 22.
  • the second ceramic member and the permanent magnet are combined to one body 23, which is coated with a layer 27 of insulating material, preferable of ceramic. Two sides of this ceramic layer are lined with metal strips 25 and 26 as seen before.
  • This embodiment has the advantage that the magnet material is screened against the gases of the tube.
  • a further alteration in the example of FIG. 4 is to be seen in the fastening of the spring contact 29 to the body 15.
  • the spring contact 29 is soldered on the other side of the body 15.
  • the springs may be interconnected by a connecting member 28 made of insulating material.
  • the advantage of the relay described herein lies in its ease of construction. It is only necessary to apply, on a ceramic body, the metal lining in prescribed conductive paths and to solder on the contacts.
  • the metal lining may be applied, for example, by means of the extremely simple and well known technique of screen printing.
  • At least one movable relay contact arranged to cooperate with said at least one fixed contact, there- 4 by forming at least one switch, said at least on movable contact being made of magnetizable material;
  • At least one metal coating on said support providing a soldering surface attached to said at least one movable contact and at least one of the remainder of said pins so as to provide at least a part of a conductive path between said at least one movable contact and at least one of the remainder of said pins.
  • At least one movable relay contact arranged to cooperate with said at least one fixed contact, thereby forming at least one switch, said at least one movable contact being made of magnetizable material;
  • At least one metal coating on said support providing a soldering surface attached to said at least one of said contacts and at least one of said pins so as to provide at least a part of a conductive path between said at least one of said contacts and at least one of said pins.
  • soldering surface includes a first surface attached to said fixed contact and a second surface attached to said movable contact, and includes two electrically insulated portions, one of said surfaces providing at least a part of the conductive path between said at least one fixed contact and at least one of said pins and the other surfaces providing at least part of the conductive path between said at least one movable contact and at least one of said pins.
