Definitions

  • the invention relates to an electromagnetic relay with multiple contact spring sets, whose movable contact springs are controllable by an operating member, actuated by the relay armature, which is movable transversely to the longitudinal extension of the contact springs.
  • Known relays of this type employ a contact spring bank which consists of a plurality of individual parts which are necessarily affected with more or less great dimensional tolerances.
  • each spring set preferably a switchover or double-throw contact set, or a pair thereof, form a separately mountable contact unit with a plurality of such contact units, controllable from a common operating member, forming a multiple contact spring bank.
  • the special advantage of an arrangement according to the invention, achieved through the module principle utilized, is that the dimensional tolerances of the individual contact units are not cumulative. Therefore, a relatively large number of contact units can be arranged without difficulty, one behind the other, in which case the operation of the contact spring sets takes place through a common operating member, whose operational dimensions are fixed to suitable tolerances.
  • An expedient form of construction embodying the invention provides, for the mounting of the separately mountable contact units and of the unit forming the electromagnetic system, a U-shaped resilient carrier which preferably consists of a non-magnetic material.
  • a U-shaped resilient carrier which preferably consists of a non-magnetic material.
  • recesses are provided and arranged within close tolerances, into which corresponding additional elements of the contact units, preferably in the form of pins, are disposed.
  • Such recesses can be constructed, for example, as respective holes or slots.
  • the terminals of the contact units can be arranged in a desired raster or pattern, and likewise such terminals can be designed as soldered or plug connections.
  • FIG. 1 is a front elevational view of a relay arrangement embodying the invention, with a portion of the carrier being broken away;
  • FIG. 2 is a transverse section through the carrier with the contact units illustrated in elevation.
  • the relay arrangement as illustrated in FIGS. 1 and 2 is provided with six contact units and the unit forming the cooperable electromagnetic system, three of the contact units being visible in FIG. 1, Where the carrier is broken away.
  • the fixed contact springs bear the reference symbols k1 and k3, respectively, while the movable contact spring, operable by an actuating member B, is designated as k2.
  • the contact springs k1, k2 and k3 of each unit K are supported in a mounting structure with terminals extending therefrom, as illustrated in FIG. 1.
  • the actuating member B in operation, is moved in the direction of the arrow by the relay armature RA, when the electromagnetic system EM (appearing in broken lines) is connected to a control voltage.
  • the contact units are supported in a carrier T, which is of U-shape in transverse cross section, by interlocked and clamped connection.
  • a carrier T which is of U-shape in transverse cross section, by interlocked and clamped connection.
  • the two shanks or legs T1 and T2 of the U-shaped carrier T are resiliently constructed.
  • the shanks T1 and T2 are provided with recesses A, which in the embodiment illustrated are designed as round or elongated holes, the manufacture of which recesses can be effected with very close tolerances.
  • Each of the respective contact units and the magnetic system EM carry a plurality of projections, which are illustrated in the form of pins Z.
  • spring members are provided, which, in the present example of construction, are defined by parallel slits PS.
  • the connecting portions remaining between the recesses A and the parallel slits PS provide a more or less resilient gripping action on the pins Z of the contact devices K, whereby a firm connection there between is achieved.
  • An electromagnetic relay comprising:
  • each of said units having a set of at least two contact springs with one of said contact springs being movable
  • each of said units being mounted on said common carrier in a line generally parallel to the normal direction of movement of said movable springs
  • said common carrier having a series of recesses formed therein alongside said line of units, each of said units having projections cooperable with said recesses to fixedly position said units in a given relationship with each other.
  • An electromagnetic relay comprising:
  • each of said units having a set of at least two leaf spring contacts with one of said contacts being movable
  • each of said units being mounted on said common carrier in a line generally parallel to the normal direction of movement of said leaf springs,
  • each of said units having means associated therewith for being received within one of said recesses to fixedly position said units in a given relationship with each other,
  • An electromagnetic relay having sets of multiple contact springs, the movable contact springs of which are controllable through an actuating member whose movement transversely to the longitudinal extension of the contact springs is controlled by the armature of the electromagnetic system, comprising:
  • said carrier being generally U-shaped in transverse cross section with the oppositely disposed shank portions thereof being relatively resilient and adapted to receive said contact units therebetween whereby said shanks exert clamping force on said units,
  • said units being assembled in adjacent relation on said common carrier with one contact set of each unit being in operative alignment and controllable by the common actuating member operable by the relay armature,
  • each contact unit and the carrier for maintaining said units in fixed operative relation with respect to each other whereby the contact units form a multiple contact bank
  • said contact units having pins cooperable with holes formed in the shanks of the carrier member
  • each contact unit being cylindrical and others associated with said contact unit being elongated slots, portions of the shanks of said carrier adjacent to said holes being removed whereby a portion of a sidewall of each hole is relatively resilient and adapted to apply compression forces on the pin disposed in such hole to firmly retain such pin therein.
