Definitions

  • This invention relates to an electromagnetic relay for use in a high-frequency circuit.
  • a single-pole relay for switching high-frequency currents has been proposed in which a contact system contained in an elongate shield casing is disposed at one side of the relay coil and includes two contact springs mounted in an actuator which is moved between two switching positions in a direction perpendicular of the relay coil by means of an L-shaped armature due to energization of the coil.
  • the two contact springs extend parallel to the coil axis and cooperate with a total of three fixed contacts inserted in the high-frequency circuit to be switched by the relay, so as to form a single-pole switch-over contact system.
  • the electromagnetic relay of the present invention comprises a coil; an armature block mounted for pivotal movement between two switching positions by energization of the coil; a pair of contact systems disposed on opposite sides of the armature block, each contact system being surrounded by electrically conductive shield means and including a first fixed contact disposed in the high-frequency circuit, a second fixed contact connected to the shield means, and a movable contact; and actuator means linking the movable contacts to the armature block for causing engagement between each movable contact and the associated first and second fixed contact, respectively, in either switching position of the armature block.
  • each movable contact is formed by a contact spring mounted in a separate actuating member which is independently coupled to the armature block.
  • each such actuating member is formed by a card mounted for slidable movement generally perpendicularly to the sides of the armature block, with one end of the card abutting the armature block and the opposite end being biased by a spring towards the armature block.
  • a magnet system B is disposed in the center of the relay, and two contact systems A are disposed on both sides of the magnet system B.
  • the magnet system B includes a coil 1 wound about a bobbin 14 located in a base member 4, with the axis of the coil 1 extending parallel to a center line of the base member 4.
  • the ends of the coil 1 are connected to coil terminals 21 which extend downwardly through the bobbin 14 and the base member 4.
  • a generally U-shaped yoke 12 extends through a central bore of the bobbin 14. Both ends of the yoke 12, which form magnetic pole pieces 2, extend from the ends of the bobbin 14 upwardly and perpendicularly with respect to the coil axis. Non-magnetic separating plates 22 are provided on the two opposite lateral faces of each pole piece 2.
  • a generally H-shaped armature 3 is pivotally mounted about an upwardly extending shaft 16 integrally formed on a bearing plate 25 mounted on the bobbin 14.
  • the armature 3 contains two parallel pole plates 17 and a permanent magnet 15 disposed therebetween in such a manner that the pole plates 17 abut opposite poles of the magnet 15.
  • the ends of the pole plates 17 cooperate with the pole pieces 2 of the yoke 12.
  • the separating plates 22 disposed on opposite faces of each pole piece 2 have different thicknesses to achieve a monostable relay function, in which the position shown in Fig. 1 is the inoperative switching position.
  • the armature 3 When the coil 1 is energized, the armature 3 will rotate counter-clockwise about the shaft 16 to the other switching position in which the respective other ends of the pole plates 17 abut those faces of the pole pieces 2 where the thicker separating plates 22 are provided. When the coil 1 is deenergized, the armature 3 will return to the rest position shown in Fig. 1.
  • a polarized electromagnetic relay having a magnet system of the general type so far described is known from US patent specification No. 3 993 971.
  • each contact system A includes a central fixed contact 6, a pair of outer fixed contacts 7 disposed to form, with the central contact 6, a straight line parallel to the coil axis, and a pair of movable contact springs 8, also generally extending parallel to the coil axis.
  • the fixed contacts 6, 7 are connected to respective contact terminals 26, 27 which extend downwardly through the base member 4, as shown in Figs. 2 and 3.
  • Each bifurcated contact spring 8 is embedded in an actuator card 5 so as to project from both sides of the card at substantially equal lengths.
  • Each card 5 slidably engages a guiding groove 29 provided in the base member 4 as shown in Figs. 1 and 3.
  • the inner end of each card 5 abuts against a side surface of the armature 3, and a return spring 19 engages the outer end of the card 5 to bias the card against the armature 3.
  • a common return spring 19 is provided for both cards 5 disposed on the same side of the armature 3.
  • each contact spring 8 is disposed between an outer fixed contact 7 and an outer ground contact 10.
  • the inner end of each contact spring 8 is disposed between the central fixed contact 6 and a central ground contact 11.
  • the central fixed contact 6 and the central ground contact 11 are of increased width for cooperation with both contact springs 8 of the same contact system A.
  • separate middle contacts may be provided for cooperation with the two contact springs to provide a four-contact system.
  • Each contact system A is surrounded by an open-top elongate shield casing 9 which is shown as such in Figs. 4 and 5.
  • a total of six ground terminals 20 are formed by punching and bending strips from the side and bottom walls of the casing 9. These ground terminals also extend downwardly through the base member 4 as shown in Fig. 2. Further strips of material are cut and bent from the side wall of the casing 9, which form the ground contacts 10 and 11.
  • appertures 30 and 31 are provided through which the fixed contacts 7 and 6 project into the interior of the shield casing 9, as shown in Fig. 1.
  • the side walls of the casing 9 are further provided with windows 18 through which the cards 5 extend.
  • a pair of projections 37 may be provided on the bottom wall of the casing 9 in alignment with the two lateral edges of each pair of opposing windows 18 to guide the respective card 5.
  • the shield casings 9 are inserted in recesses 13 of the base member 4 as shown in Fig. 3.
  • the bottom surface of these recesses 13 is situated below the bottom surface of the grooves 29 which serve to guide the cards 5.
  • the shield casings 9 are held in place in their recesses 13 by means of their ground terminals 20 which penetrate through the base member 4.
  • a cover 23 closes the upper side of the base member 4 and carries two shield plates 24 which serve to close the open tops of the shield casings 9. As shown in Fig. 6, the underside of each shield plate 24 is provided with two pairs of parallel ribs 38 which further serve to guide the respective cards 5.
  • the shield casings 9 and shield plates 24 are of highly conductive material, just as are the fixed contacts 6, 7 with their contact terminals 26, 27 and the contact springs 8, the base member 4, the cover 23 and the cards 5 are of insulating, preferably synthetic material,just as all other components of the relay which have neither an electrical nor a magnetic function.
  • the armature 3 When the armature 3 is in a neutral center position in which its longitudinal axis extends parallel to the coil axis, the whole relay structure is symmetrical with respect to that axis and also with respect to an axis which is perpendicular thereto and extends vertically in Fig. 1.
  • Fig. 7 shows a schematic cross-sectional view of an embodiment in which the base member 4 is provided with holes 39 to permit a sealant, which is used to seal the terminals 20, 21, 26 and 27 to the base member 4, to reach the bearing plate 25 for the armature 3 and to serve as an adhesive for fixing the bearing plate 25 to the base member 4.
