Definitions

  • This invention relates to relays, more particularly suitable to relays designed for use relays heretofore in use the armature was either spring supported or pivoted. These methods of supporting the armature, result ed among other inconveniences in that such relays were lazy as compared with the present relay.
  • the armature of the relay embodying the present invention is acted upon only by the attracting force of the coils and cores of the relay and by gravity, so that forces variablein any way, whatever such asspring tensions, frictions in bearings and the like are entirely eliminated. Thereby an accurate and permanently equal adjustment is rendered possible by properly selecting the weight of the armature and the air gap between the armature and the stationary contacts and a reliable and permanently equal operation of the relay'may be secured not withstanding comparatively weak energizing currents.
  • a plurality of pairs of cores may be arranged in a pair'of coils common to such cores, such' cores being separated from each other by insulating partitions and a freely movable armature associon certain spots of the stationary contacts is ated to each pair of cores being arranged below the latter.
  • Fig. 1 is a vertical section of the relay on the line I-I of Fig. 2.
  • Figure 2 is a vertical section of the relay on the line IIII of Fig. 1.
  • the relay according to Figs. 1 and 2 is provided with two coils 1, with the windings 2.--
  • the cores 3 of the coils serve also as current supply conductors for the stationary relay contacts 6.
  • leads 4 are connected to these cores.
  • three circuits are controlled simultaneously by the relay. From Fig. 1 it is seen that in each coil three cores 3 separated from each other by insulations 5, are arranged each of such cores being provided with a relay contact 6.
  • an armature 8 is arranged and provided with two contacts 7 corresponding to the contacts 6 of the cores such contacts 7 being pointed for increasing the specific contact pressure.
  • the armature is 10- cated below the contacts 6 and is raised from its position of rest, overcoming gravity, whenever the relay is energized. Its contacts 7 then bear against the contacts 6 making the circuit. The flux of force passes through the I contacts themselves and the maximum at.- traction pressure of the armature is utilized a the contact pressure. On de-energizing middle part with an opening 13 shown in Fig.
  • the construction of the relay provides a simple means for adjusting the sensibility, the sensibility of the relay being adjusted by varying the air gap between armature and core, that is to say the distance between the contacts 6 and 7 in the position of rest of the armature. This is done by interposing washers 11 of non-magnetic material of different thicknesses, between the armature 8 and the supporting plate 9. The more the air gap is reduced in this way the weaker is the energizing current of the relay required for attracting the armature.
  • a successive making of such circuits may be brought about by properly selecting the washers for the armatures associated to such circuits.
  • the armature of the relay is freely movable between the two extreme positions. Only the attractive force of the relay and gravity act on the armature as forces, so that forces variable for any reasons whatever such as tensions of springs, friction of bearings and so on are eliminated. Therefore an exact and permanently equal adjustment of the relay is possible, by properly selecting the armature weight and the air gap and a reliable and permanently equal actuation of the relay may be secured notwithstanding very small intensities of the exciting current.
