Definitions
- the axes 01, 02 are fixed relative to the housing 11 and the angular displacement oL, of the contact-carrying lever 15 around the axis 01 in response to the movement of the hook in the event of tripping on fault (FIG. 6) is less than angular displacement OE2 of the lever 15 around the axis 01 in response to the setting in position “stop of the button 22 by rotation around the axis 03 (FIG. 7).
- the distance L1 (FIG.
- the button 22 capable of rotation about the axis 03 cooperates via the connecting piece 24 with studs 24B, 24C with the cam or the imprint 23B, 23C of the control piece 23.
- the finger 23A does not is not applied in the closed position against the shoulder 15C.
- the position of the control part 23 is not changed during the fault triggering phase which has just been described.
- the part 21 is therefore forced to pivot slightly clockwise around the axis 01 so that its wedge 21G releases the hook 20 which, under the effect of the return spring not indicated, returns to the armed position of Figures 5 , 7 and 8 in which it is engaged on the rotary screen itself returned to its contact release position.
- the switch in FIG. 10 differs from that in FIGS. 5 to 9 in that the button 22, the connecting piece 24 and the control piece 23 are replaced by a manual rocker 100 carrying a gripping element 122 and constituting the piece control 123 for sectioning and resetting; the rocker 100 is pivotally mounted on an axis coincident with the axis 02.
- the pivot axis of the rocker could of course be parallel to the axis 02 and distinct therefrom.
- the spring R is permanently applied by its branch RB against the end 15B of the lever 15 and therefore exerts on it a torque C1 in order to ensure the contact closing pressure; it applies by its branch RA permanently a force to the drive part 21, this force being transmitted or not to the lever 15 depending on whether the hook 20 releases or locks the part 21; when it is transmitted, the aforementioned force is reflected on the lever 15 by a torque C2 antagonistic to the torque C1 and in absolute value greater than this, this producing an opening of the movable contact of angular amplitude ⁇ 1 (FIG. 11
- elastic retaining means 11 A, 100A visible in FIG. 12 are provided, disposed respectively in the housing 11 and the rocker 10 and of which at least one is endowed with elasticity in a direction perpendicular to the plane of the figure and is shaped, on the one hand, to let the contact carrier lever 15 pivot abruptly when the contacts open, on the other hand, to hook said lever on closing in order to retain it at the start of the closing maneuver and release it abruptly at the end of the closing maneuver.
- the pivoting hook 20 can advantageously be housed in bearings forming part of the housing by presenting, on its two end faces perpendicular to the axis 04, a tenon, for example a flat 20E, and respectively a notch 20F, for example of flared shape (FIG. 14).
- the post can thus be coupled with play at the notch of the hook of a neighboring pole.
- the tripping on fault of one pole causes the tripping of the other poles of the switch when the latter is multipolar, since the rotation of the plate 20E of the hook 20PA of the pole A takes place with a slight dead travel allowing the opening of the contacts of pole A, then causes the rotation of the hook 20PB of pole B.
- any other mechanical coupling producing a slight delay in transmission from pole to pole could be integrated into the switch.
- the manual control acts on the hook 20 to obtain a sudden opening of the contacts.
- the control part 23, 123 comprises, in addition to the drive element 23A, 123A, a transmission part 28 articulated on said control part by means of an axis bearing 07.
- the part 28 has the form of a fork one branch 28A of which is guided in a curved guide 29 formed in one face of the housing and the other branch 28B of which is elastic and makes it possible to drive the hook 20 during manual opening (FIG. 15), while sliding with bending elastic on the hook during resetting (figure 17).
