Definitions

  • the present invention relates to movable contacts for electromagnetic relays.
  • FIGURE 1 is a part-sectional elevation of a relay having a movable contact designed in accordance with the present invention.
  • FIG. 2 is a fragmentary section along the lines IIII of FIG. 1.
  • the frame 1 of a relay carries a coil 2 and by means of an insulating plate 3 carried by an upwardly bent portion of the frame 1, an immovable contact 4 connected with one conduit of a terminal 5.
  • a movable armature 6 is supported at 7 on another upwardly bent portion of the frame 1 and comprises a cranked extension 8 which cooperates with an abutment 9 integral with the frame 1.
  • a helical spring 11 is secured to the abutment 9 and to the portion of the armature 6 which is on the right (FIG. 1) of its supporting point 7.
  • the movable contact comprises a contact element 13 adapted to engage the immovable contact 4 in circuit closing position and riveted to one end of a conduit strip 14.
  • the other end of the conduit strip is set into the mold of an insulating block 15, which is of parallelepiped form, by example in the embodiment shown.
  • the insulating block 15 is secured to and supported by the 2,988,615 Patented June 13, 1961 ICC armature 6 by any suitable securing means, such as, for example, counter-sunk screws 16, shown in broken lines in FIG. 1.
  • the contact strip 14 which carries the movable contact 13 may be of a shape different from that shown in the drawing.
  • the insulating block 15 may be secured to the armature 6 by other means than those shown by example in the drawing.
  • a frame In an electromagnetic relay, a frame, a coil receiving a core member supported by said frame, a double-armed armature spring-biased to said frame and disposed opposite said core member, a terminal receiving two conduits secured to said frame, an immovable contact supported by and connected with one of said conduits of said terminal, an insulating block carried by said armature, and a resilient conduit strip, one end of the latter having a tongue cut out thereof and bent outwardly and defining a recess formed by said cut-out, said one end of said conduit strip being molded into said insulating block, a movable contact secured to the other end of said conduit strip and adapted to engage said immovable contact, and a conduit member connecting the end of said tongue with the other of said conduits of said terminal.
