Definitions
- the invention relates to a mechanism for abrupt engagement and tripping of a translation switch, in particular of the type with friction contacts or jaws.
- the main application targeted by this switch concerns the field of industrial power switches.
- the translation switches are appreciated for their resistance to short circuit current because they present 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 beats observed with other types of contacts during peaks of intensity.
- the known standard embodiment of the actuation mechanism of a translation switch uses a knee switch.
- This control consists of a connecting 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 abrupt engagement and trigger mechanism according to the invention is remarkable by the association of a broken connecting rod with a back and forth device urged in abrupt transverse movements of engagement and trigger by two opposite thrust means gradually energized and suddenly released, association comprising, moreover, means for tilting the connecting rod allowing remote control. in trigger.
- the mechanism according to the invention gives the translation switch, which is equipped with it, multiple advantages such as:. the low energy remote triggering command,. the exceptional speed of triggering and switching on,. the possibility of using the same electromechanical tripping device for switches of different breaking intensity up to high values,. the use of a combination of mechanical mounting means if mp le, . the possibility of triggering manually,
- FIG. 1 is a general plan view of the abrupt engagement and trigger mechanism according to the invention in the trigger position.
- Figure 2 is an elevational view of the entire mechanism according to the invention.
- . 3 shows, in plan view, a broken rod of another type.
- Figures 4 to 6 are schematic plan views, showing respectively in the released position in the intermediate position and in the engaged position the mechanism according to the invention.
- the mechanism according to the invention is actuated manually from an operating handle integral with the control axis 1.
- This axis pivotally mounted on a plate and in elastic return to the release position, causes a broken connecting rod 2 of known type to tilt by means of a pivoting mechanical assembly 3.
- This assembly includes an actuation lever
- This lever 4 mounted pivoting about the control axis 1, for example by a doui Ile 5.
- This lever 4 is articulated by one of its ends on the broken 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 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 break 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 instantaneously releases the energy accumulated during the compression phase in order to cause the sudden engagement.
- This lever has one end with return, the edge of which forms a stop front.
- the broken connecting rod is preferably chosen from the embodiment shown in FIG. 1. It could just as easily have the technical characteristics of another embodiment, for example that shown in FIG. 3 providing substantially the same results.
- the broken connecting rod 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 via an axis 14.
- the broken connecting rod used is formed by two parallel plates such as 15 carrying a blocking mechanism 16 made up of the following elements: a blocking lever 17 in the rifle shape having a receiving notch 18, a trigger lever 19 pivoting, with lug of end 20, with rectilinear transverse unlocking 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 interlocking rod.
- the other type of broken connecting rod shown in Figure 3, does not differ fundamentally from that already described. It consists of two yokes 24, of the two hinge pins 12 and 14 at the end by which it is placed in the mechanical compression and rebound assembly 8.
- the end of the interlocking link 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 the same.
- a stop pin 29 moving in a curvilinear opening 30 has been provided here, on the end of the locking rod.
- Said interlocking rod carries an interlocking spring 31 held between two end flanges 32 and 33. It comprises a longitudinal slot 34 cooperating with the axis 35 back and forth which drives the movable contact carrier assembly between the switch-on position and switch-off position.
- the rod 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 link, called trigger 37, mounted articulated at one of its ends on an axis 38 and engaging 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. It carries a trigger spring 40 held by flanges 41 and 42.
- the mechanism according to the invention also comprises a remote control device for triggering 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 core 46.
- the intermediate trigger lever 43 has a generally angled shape with a return 47 with double oblique ramp 48 allowing an action on the trigger lever at any time of the race.
- Remote triggering is triggered by a low energy pulse on the coil 45.
- the axis 35 of the back and forth 9 is integral with the movable element in "translation carrying the jaw contacts of the switch. It may have a thicker base on which the end of the retaining lever comes to lock. .
- 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 10 to tilt, the double oblique ramp 48 of which comes into contact with the lug 20 of the trigger lever 19.
- the latter pivots forward by bringing its transverse blocking element into the position of release.
- the locking lever opens and releases the tip 36 of the locking rod for its rotation.
- the rectilinear connection breaks with projection of the connecting rod outside. This movement is favored by the trigger spring which relaxes and causes the sudden trigger by the displacement of the axis 35 in the opposite extreme position.
- the retaining lever is returned to the locked position as soon as the spring 11 triggers.
