Definitions

  • the present invention relates to an armature holding structure using a hinge-spring in an electromagnetic relay and the hinge-spring used.
  • an armature holding structure is used in order to support an armature rotatably on one end portion of the yoke of the electromagnet.
  • armature holding structure in an electromagnetic relay examples include Figs. lA, 1B, 2A and 2B.
  • the armature 2' having a rectangular aperture 23' and a groove 22', rides on one end of the yoke 13', having a rectangular aperture 132', of the electromagnet 1'.
  • a hinge plate-spring 3' having the ends partly rolled under (Figs. lA, 1B) or a hinge plate-spring 3" having several bent portions (Figs.
  • Such hinge plate-spring 3' or 3" is manufactured by the process of punching a planar plate having a predetermined size from a sheet and then working such punched planar plate to give either a shape in which the ends are partly rolled under (Figs. lA, 1B) or a shape having several bent portions (Figs. 2A, 2B).
  • the process of attaching the hinge plate-spring 3' or 3" to the groove 22' and the rectangular aperture 132' requires specially skillful work, without which the preliminarily given shape and the preliminarily stored resilient force of the hinge plate-spring 3' or 3" are likely to be departed from so that uniformity of the operating characteristics of the produced electromagnet relays cannot be achieved.
  • the hinge plate-spring 3' or 3" is manufactured by the process of punching a planar plate from a sheet having a large size in the longitudinal direction, which sheet has been manufactured by the rolling process, the degree of utilization of the sheet as a material for such punched planar plate cannot be increased. This is because the punching of the planar plate should be carried out so that the longitudinal direction of the hinge plate-spring coincides with the longitudinal direction of the sheet in order to ensure the metallurgical strength of the hinge plate-spring.
  • Figs. 2A, 2B The structure of Figs. 2A, 2B is disclosed in Japanese utility model application laid-open No. 53-89541.
  • an armature holding structure using a hinge-spring in an electromagnetic relay comprising an electromagnet having a core, a coil and a yoke, an armature and a hinge-spring coupled to both said yoke and said armature, characterised in that'the hinge-spring is a wire spring,one end of the hinge wire spring is held in a hole in the yoke, the other end of the hinge wire spring is held in a hole in the armature, and the intermediate portion of the hinge wire spring passes through a groove in a member of the relay, along the side surfaces of the yoke and the armature and over the outer surface of the armature, whereby a pivot support structure for the armature at the end of the yoke is maintained by the hinge wire spring.
  • a hinge-spring for use in an armature holding structure in an electromagnetic relay, characterised in that the hinge-spring is a wire spring consisting of first, second, third, fourth and fifth portions, each of the first to fifth portions being arranged to form a predetermined angle with respect to the adjacent portion, the first and the fifth portions being adapted to be inserted into respective holes in a yoke of an electromagnet and the armature of the electromagnetic relay, and the second and the fourth portions lying in the same plane, whereby the resilient force stored in the wire spring can be used for maintaining a pivot support structure for the yoke and the armature.
  • FIG. 3 An electromagnetic relay using a wire hinge-spring for holding an armature in accordance with an embodiment of the present invention is illustrated in a perspective view in Fig. 3.
  • the detailed structures of the device of Fig. 3 are illustrated in Figs. 4, 5, 6 and 7.
  • the important portion of the device of Fig. 3 comprises an electromagnet 1 consis.ting of a core 11, a coil 12, a bobbin 14, a yoke 13, an armature 2, a wire hinge-spring 3 and a base block 4 having a shelf 41 projecting from the base block 4.
  • other elements of the electromagnetic relay are provided, such as a card, a movable contact spring, a fixed contact spring and a restoring spring to form a or complete assembly of the elements of the electromagnetic relay.
  • the motion of the armature 2 causes, via the card, the movement of the movable contact spring to cause the movable contact to come in contact with the fixed contact.
  • Such complete assembly of the elements is encased in a housing consisting of the base block 4 and a cover (not shown).
  • the yoke 13 of the electromagnet 1 is fixed to the base block 4.
  • the shelf 41 is provided for determining the position of".the electromagnet -1 with respect to the base block 4.
  • the armature 2 is pivoted at the inner corner thereof on the edge of the yoke 13.
  • the wire hinge-spring 3 is provided to combine the armature 2 and the end portion of the yoke 13.
  • the wire hinge-spring 3 consists of a first 31, second 32, third 33, fourth 34 and fifth portion 35.
  • the first portion 31 is held in a hole 131 in the yoke 13.
  • the second portion 32 is held in a groove 411 in the shelf 41.
  • the third portion 33 lies on the side surfaces of the shelf 41, the yoke 13 and the armature 2.
  • the fourth portion 34 lies along the ridge 21 of the armature 2.
  • the fifth portion 35 is held in a hole 22 in the ridge 21 of the armature 2.
  • the wire hinge-spring 3 is made of, for example, stainless steel.
  • the shape of the wire hinge-spring 3 is as shown in Fig. 7, wherein the second portion 32 and the fifth portion 35 lie in the same plane.
  • the resilient force F 1 which is exerted in the direction parallel to the direction of the third portion 33, causes the fourth and the fifth portions 34, 35 to be pressed inwardly toward the second portion 32.
  • This resilient force F 1 acts as a combining force between the ridge 21 of the armature 2 and the end portion of the yoke 13.
  • the armature 2 is mounted at the inner corner thereof on the edge of the yoke 13. Then, the first and the second portions 31, 32 are inserted into the groove 411 and the shelf 41 until the first portion 31 is inserted into the hole 131 in the yoke 13.
  • the third portion 33 is moved clockwise along the side surfaces of the shelf 41, the yoke 13 and the armature 2, with the fourth and the fifth portions 34, 35 being simultaneously pressed outwardly by the force F 2 , thereby enabling the fourth' and the fifth portions 34, 35 to go over the ridge 21 of the armature 21, until finally the fifth portion 35 is inserted into the hole 22 in the armature 2.
  • the resilient force F 1 maintains the pivot relationship between the armature 2 and the yoke 13.
  • a groove 411 is provided in the shelf 41 in the embodiment of Fig. 3, it is possible to provide a groove in the inner surface of the yoke 13; also it is possible to provide grooves in both the shelf 41 and the yoke 13.
