Definitions

  • the present invention relates to contact-spring-sets, which are included in very quick switching operations.
  • Contact-spring-sets for closure and break of circuits are included in a great number of control systems often in connection with electronic components.
  • distinct closures and breaks are required. as every contact vibration can be understood as a control signal.
  • FIG. 1 shows an electromagnetic relay with a contact-spring-set for two make-contacts according to the invention.
  • FIG. 2 shows a detail, which is included in the contact-spring-set.
  • the digit 7 designates the coil of an electromagnet mounted on a yoke 8, which also carries an armature 6 and a contact-spring-set.
  • the contact-springset consists of a strip 9 of insulating material, which carries a guide bar and the contact springs 1a, 1b and a, 10b, respectively, for two make-contacts.
  • the link 4 is constructed as a double-armed lever, which is pivotal about a fulcrum in the form of a crosswise rib 4c situated between the bars 2 and 3.
  • Each lever arm terminates in a notch 4a, 4b engaged with a notch in the corresponding bars 2 and 3, respectively, as it appears from FIG. 1.
  • the bars 2 and 3 extend through oblong holes in the contact springs la, lb, 10a, 10b and through slots in the guide bar 5. They are displaceable in their longitudinal direction and mount projections 2a, 2b and 3a, 3b, respectively.
  • the bar 3 abuts the armature 6, which in turn abuts the yoke 8 by means of a stud 6a of nonmagnetic material.
  • the contact springs la and 10a are biased upwardly and abut against the projections 2a, 2b and the contact springs lb and 10b are biased downwardly and abut against projections 3a, 3b.
  • the bar 2 is thus pressed up against the link 4 and the rib 3 down against the armature 6.
  • a make-and-break contact spring assembly comprising:
  • each arm of said lever being coupled to one of said bars for displacing the bars relative to each other in response to a pivotal movement of the lever, said lever being pivotally mounted between the two bars whereby upon pivoting of the lever the two bars are displaced in opposite direction, said displacement moving the spring contacts from said one position into said other position;
  • a make-and-break contact spring assembly comprising:
  • each arm of said lever being coupled with one of said bars for lengthwise displacement of said bars in opposite direction in response to pivoting of the lever, said lever being pivotally mounted between said bars to effect said displacement in opposite direction upon pivoting of the lever;
  • each of said spring contacts being flexible either into a make position or a break position and biased to occupy a predetermined one of said two switching positions, each of said spring contacts being coupled to one of the bars, the bias of the spring contacts holding the bars in a lengthwise position relative to each other in which the spring contacts are in said predetermined switching position and lengthwise displacement of the bars against the bias of the spring contacts moving the latter toward the other one of said two switching positions;
  • stop means also constitutes an abutment for the pivot axis of said two-arm lever.
  • said drive means comprise a solenoid having an armature in the form of a pivotally mounted yoke, said one bar abutting against the yoke, energization of said solenoid causing pivotal movement of the yoke toward the solenoid core. said pivotal movement of the yoke causing displacement of said one arm into the position in which the contact springs are in said other switching position and retention of said one arm in said other switching position.
  • each of the bars has on its side'facing the other bar a protrusion.
  • said protrusions being lengthwise staggered relative to each other, each of the protrusions being in engagement with one of the spring contacts for effecting movement of the spring contacts toward and away from each other upon displacement of said one bar upon operation of the drive means.
