Definitions

  • An electromagnetic relay with the features set forth in the first part of claim 1 is known from EP-A-0 124 109.
  • the movable contacts of all contact systems are operated by one common connecting or actuating member coupled to the relay armature. If the closing and opening function of one movable contact is to be adjusted, such as by applying pressure to a spring to cause a slight deformation thereof and thus a variation in the contact pressure, such manipulation will influence the characteristics of the other movable contact springs, so that a proper adjustment of the contact assembly as a whole is difficult.
  • US-A-3,993,971 discloses another electromagnetic relay in which the armature block, contact systems and actuatoc means are arranged in a similar way as in the above prior-art relay. Moreover, the armature is privotal about a central axis with respect to which movable contacts are disposed symmetrically. That relay, however, does not provide electrically conductive shield means for individual contact systems and all movable contact springs are operated by plastic formations surrounding parts of the armature.
  • each movable contact may be individually adjusted in its switching behaviour, such as by deformation, without influencing the characteristics of the other movable contacts.
  • 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-A-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 bifurcated movable contact springs 8, also generally extending parallel to the coil axis.
  • the fixed contacts 6, 7 are conected 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. 22. 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, with their contact terminals 26, 27 and the contact springs 8, the base member 4, the cover 23 and the cards & 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.
