Definitions

  • the invention relates to a mechanism for suddenly switching on and off a translation switch, in particular of the type with friction contacts or jaws.
  • the translation switches are appreciated for their resistance to short circuit current because they have the important advantage of having a lateral socket for the contacts between two jaws, in the manner of a clamp.
  • This characteristic ensures perfect, frank and complete contact from the start of the engagement of the two parts, and eliminates the twists and turns observed with other types of contacts during peaks of intensity.
  • the known typical embodiment of the actuation mechanism of a translation switch uses a toggle control.
  • This control consists of a rod secured by one of its ends to the axis of the handle and mounted articulated by its other end on a movable axis driving in translation the movable support carrying the contacts.
  • This axis also actuates in tilting a pivoting motor lever equipped with a compression spring which forces the link in extreme positions of right or left tilting corresponding to the closing or the opening of the circuit or vice versa by the only play of the compression of the comes out between an extreme position and the central dead center.
  • the invention provides additional technical possibilities to these types of switch such as the low energy triggering remote control and very advantageous performance in triggering and switching speed by a composite control mechanism using, for each movement, the energy stored in a separate device.
  • the invention relates to an abrupt switching on and off mechanism, remotely controlled, for a translation switch comprising a contact carrier bar, said mechanism consisting of a chain of articulations and characterized in that said chain consists of a manual reset lever from a rotary movement, a broken connecting rod and, a back and forth device articulated by one of its ends on the mechanical support of the 'switch and by its other end on the broken rod, said back and forth device consisting of a trigger rod each carrying a thrust means and hinged together along a common axis integral with the contact carrier bar which moves the along the connecting rods in perfect translational movements when they come into alignment position, the pushing means being tensioned during engagement for one by a limit switch and for the other by a remote trigger means, acting on the broken connecting rod.
  • the mechanism according to the invention is actuated manually from an operating handle secured to the control axis 1.
  • This axis pivotally mounted on a plate and in elastic return to the position of tripping, causes, in tilting, a broken rod 2 of known type, by means of a pivoting mechanical assembly 3.
  • This assembly comprises an actuating lever 4 mounted pivoting about the control axis 1, for example by a bushing 5.
  • This lever 4 is articulated by one of its ends on the broken connecting rod 2 and connected by its other end to a curved light 6 provided in a pivoting sector 7, integral with the control axis 1.
  • the broken connecting rod 2 is mounted articulated in a mechanical assembly 8 for compression and expansion proceeding by aligning the elements of the composite arm in which it is inserted. It cooperates with a back and forth engagement and trigger device 9 as an articulated connecting element, making it possible to align the articulation points in the compression phase and the zuptuze in the trigger phase. It also cooperates by pushing, at the end of alignment, with a tilting retaining lever 10, returned to the retaining position by a spring 11, which instantly releases the energy accumulated during the compression phase, in order to cause the engagement sudden.
  • This lever has one end with return, the edge of which forms a stop front.
  • the broken connecting rod 2 is preferably chosen in the embodiment shown in Figure 1. It could just as easily have the technical characteristics of another embodiment, for example that shown in Figure 3 providing substantially the same results.
  • the broken connecting rod 2 is articulated, on the one hand at the end of the actuating lever 4 by a pin 12 and, on the other hand, at the end of an interlocking rod 13 by means of an axis 14.
  • the broken connecting rod used is formed by two parallel plates such as 15, carrying a locking mechanism 16, consisting of the following elements: a locking lever 17 in the rifle shape having a receiving notch 18, a trigger lever 19 pivoting with lug d end 20 with a transverse rectilinear locking element 21 cooperating, on the one hand, with the end of the locking lever 17 and, on the other hand, with a receiving groove 22 having a clearance ramp 23 at the end of the connecting rod 13.
  • the end of the engagement rod 13 has an enlarged shape 25 with a corner notch 26 in which is housed the end of a blocking sector 27 secured to a pivoting trigger lever 28.
  • the operating principle remains identical.
  • Said engagement rod 13 carries a spring 31 engaged between two end flanges 32 and 33. It comprises a longitudinal slot 34 cooperating with the axis35 of the back and forth 19 which drives the movable contact carrier between the engagement position and the position of trigger.
  • the link is shaped as a point at its front end, articulated on the broken rod 2. This profiled end has a cut revealing the receiving groove 22, the release ramp 23 and a point 36 which is received in the receiving notch 18 and locked in this position by the locking element 21.
  • the back and forth device 9 consists of a second so-called trigger rod 37, mounted articulated at one of its ends on an axis 38 and coming to engage on the axis 35 in a longitudinal slot 39 allowing its movement transverse.
  • the trigger rod 37 may also include a longitudinal light in its rear part, which will provide an identical result.
  • the mechanism according to the invention also comprises a triggering remote control device in the form of an intermediate trigger lever 43 pivotally mounted and actuated by a pushing means 44, for example of the electromagnetic type in the form of a coil. 45 with plunger 46.
  • the intermediate trigger lever 43 has a generally angled shape with a return 47 with a double oblique ramp 48 allowing action on the trigger lever 19 at any time during the race.
  • the axis 35 of the back and forth 9 is integral with the movable unit in translation carrying the jaw contacts of the switch. It may have a thicker base on which the end of the retaining lever abuts.
  • the rotation of the handle generates, via the breeze rod 2 in the locked state, a longitudinal type force.
  • the broken connecting rod 2 remains in the locked state and transmits the force to the engagement spring 31 carried by the engagement rod 13.
  • the pushing force is transmitted to the engagement spring 31 which abuts, by its flange d end 32 against the axis 35 of the reciprocating device 9 retained in this position by the end of the retaining lever 10.
  • the compression continues with the pivoting of the actuation lever 4.
  • the trigger is produced by an impulse on the device 44, for example a coil and a plunger, or any other equivalent means.
  • the displacement of the core causes the intermediate trigger lever 43 to tilt, the oblique double ramp 48 of which comes into contact with the lug 20 of the trigger lever 19.
  • the latter pivots forward by bringing its transverse locking element 21 into position of clearance.
  • the locking lever 17 opens and releases the tip 36 of the interlocking rod for its rotation.
  • the zuptuze of the rectilinear connection occurs with projection of the rod outside. This movement is favored by the trigger spring 40 which relaxes and causes the sudden trigger by the displacement of the axis 35 in the opposite extreme position.
  • the retaining lever 10 is returned to the blocking position as soon as the spring 11 triggers. It then suffices to maneuver the handle to drive the broken connecting rod 2 into blocking then into alignment to cause a new engagement.
