Definitions

  • the present invention relates to electromagnetic relays having a frame carrying a core and a mounting comprising fixed contacts and relay terminals constituted by tongues of which one part, preferably the central portion, is embedded during the moulding in a block of insulating material.
  • the block of insulating material may have the general form of an elongated parallelepiped and the grooves may be longitudinally or transversely oriented relative to said block.
  • FIGURE 1 is a front elevational view of a relay, the fixed contacts of which and the relay terminals are mounted in accordance with the present invention
  • FIG. 2 is a side elevation of the relay terminals shown in FIG. 1;
  • FIG. 3 is a fragmentary top plan view corresponding to FIG. 1;
  • FIGS. 4 and 5 are, respectively, front and side elevational views of a modification of the relay.
  • FIG. 6 is a plan view corresponding to FIG. 4 of the part of the plate which carries the insulating supporting strips of the terminals.
  • the relay frame 1 carries the coil 2 and a movable armature 6 pivoted at 7 on the frame 1.
  • the armature 6 comprises a cranked extension 8 which co-operates with an abutment 9 integral with the frame 1.
  • a return spring 11 is'provided for the armature 6.
  • the relay is bipolar and comprises two fixed contacts 21, two terminals 22 for current supply to the movable contacts 12 by flexible cables 23, and two terminals 24, 25 which serve to conduct the current to the relay winding 2.
  • Two other terminals 26 are not used in the mounting illustrated, but may serve in the numerous other more complex mountings, notably when the relay is installed in inverters.
  • Each of the terminals comprises a metal tongue of which the central portion is embedded in a block 27 of insulating material of the general shape of a parallelepiped, forcibly engaged in a notch of the relay frame of which the two edges, forming tenons, are respeca coil, and at least 3,012,117 Patented Dec. 5, 1961 tively engaged in two longitudinal grooves 28 forming mortices extending over the full length of the block on which the two opposed faces perpendicular to those across which the tongues emerge (FIGS. 2 and 3).
  • the extremities of the tongues which project from the relay may serve for the branching of external circuits while their inner extremities may serve, for example, to carry the contact elements of the fixed contacts (contact element 31 on the tongue 21), for the connection from the winding (tongues 24, 25), and for the connection of a current supply cable to a movable contact (cable 23 connecting the tongue 22 to the movable contact 12).
  • Modification disclosed in FIGS. 4 to 6, are the insulating block 40, which support the tongues are fixed on the frame 1' of the relay by one of their extremities, which is engaged in a notch 41 of the frame 1, the two edges of the notch 41 being forcibly engaged in two grooves 42 cut on two opposed faces of this extremity of the block.
  • An electromagnetic relay having a plate constituting a frame carrying a core and a coil, and at least a mounting comprising a plurality of fixed contacts and relay terminals constituted by tongues, a block of insulating material, one part of said tongues being embedded in said block, and said plate being provided on one of its edges with at least one notch having two parallel edges, and said block having two parallel grooves extending throughout two opposite faces of said block and forcibly engaged upon said parallel edges of said notch of said frame.
