Les pièces qui composent le nouveau mécanisme disjoncteur pour dispositifs électroniques, qui est préconisé, ainsi que leur montage étant décrits, leur fonctionnement est le suivant:The parts that make up the new circuit breaker mechanism for electronic devices, which is recommended, as well as their assembly being described, their operation is as follows:
Le mécanisme étant en position de repos ou de circuit ouvert (voir figure 2), on agit manuellement sur la manette -1- jusqu'à la position opposée (voir figure 3), avec quoi la bielle -8- est obligée de se déplacer en entraînant dans son déplacement, la pièce -9- cliquet qui, par l'enclenchement de la dent ou pointe -13- au bec -16- de la pièce balancier -14- la fait osciller et, par conséquent, le ressort -19- agit sur la découpure en "U" -39- de la pièce d'entraînement -22- qui est obligée de faire un mouvement de rotation sur l'axe -38-, qui détermine que la pièce -26- qui supporte le contact mobile se déplace radialement, en faisant que le contact mobile qu'elle comporte -29- se relie au contact fixe -40-, en même temps que, par l'effet de pivotement de la pièce -22- d'entraînement, le ressort -37- se tende, le circuit restant alors fermé et les pièces du mécanisme en équilibre instable.The mechanism being in rest position or open circuit (see figure 2), one acts manually on the lever -1- until the opposite position (see figure 3), with which the rod -8- is forced to move by driving in its movement, the part -9- pawl which, by the engagement of the tooth or point -13- to the beak -16- of the balance piece -14- causes it to oscillate and, consequently, the spring -19- acts on the "U" cutout -39- of the drive piece -22- which is forced to rotate on the axis -38-, which determines that the part -26- which supports the movable contact moves radially, so that the movable contact which it comprises -29- connects to the fixed contact -40-, at the same time as , by the pivoting effect of the drive part -22-, the spring -37- tightens, the circuit then remaining closed and the parts of the mechanism in unstable equilibrium.
En étant à cette position de charge ou d'équilibre instable, les pièces du mécanisme, s'il se produit dans le circuit contrôlé une forte élévation de l'intensité du courant électrique, le percuteur -41- (relié à l'électro-aimant de réglage, non représenté), se déclenche et agit sur le côté de la pièce balancier -14- en la faisant osciller, avec quoi son bec -16- se dégage de la dent ou pointe -13- de la pièce cliquet -9-, en même temps que le contact mobile -29- de la pièce support -26- s'écarte du contact fixe -40-, en déséquilibrant les pièces de l'ensemble du mécanisme, qui retourne à sa position initiale de repos ou de circuit ouvert. On arrive également à cette même position, c'est-à-dire celle de circuit ouvert, lorsqu'une faible surintensité soutenue se produit, dans laquelle le bimétal -25- s'échauffe et se plie, en faisant que le contact mobile -29- se dégage du fixe -40- et, en même temps, la bielle -24- entraîne la pièce balancier -14- en la faisant osciller de sorte que son bec -16- s'écarte de la dent ou pointe -13- de la pièce cliquet -9-, en déséquilibrant les pièces restantes de l'ensemble qui retournent à leur position de repos ou de circuit ouvert. Une fois l'anomalie est corrigée, on actionne à nouveau la manette -1- jusqu'à sa position de charge, à laquelle les pièces retournent à la position d'équilibre instable ou de circuit électrique fermé, dans lequel elles vont rester tant qu'une autre anomalie qui altère cet équilibre ne se produira pas.Being in this unstable load or equilibrium position, the parts of the mechanism, if there is a sharp rise in the intensity of the electric current in the controlled circuit, the striker -41- (connected to the electro- adjustment magnet, not shown), is triggered and acts on the side of the balance piece -14- by making it oscillate, with which its beak -16- emerges from the tooth or tip -13- of the ratchet piece -9 -, at the same time as the movable contact -29- of the support part -26- moves away from the fixed contact -40-, by unbalancing the parts of the entire mechanism, which returns to its initial position of rest or open circuit. We also arrive at this same position, that is to say that of open circuit, when a low sustained overcurrent occurs, in which the bimetal -25- heats up and bends, causing the movable contact - 29- emerges from the fixed -40- and, at the same time, the connecting rod -24- drives the balance piece -14- by making it oscillate so that its beak -16- moves away from the tooth or tip -13- of the pawl part -9-, by unbalancing the remaining parts of the assembly which return to their rest or open circuit position. Once the anomaly is corrected, the lever -1 is again actuated to its load position, at which the parts return to the position of unstable equilibrium or of closed electrical circuit, in which they will remain as long as another anomaly that upsets this balance will not happen.
De la description précédente et des représentations des feuilles de dessins annexées, on comprend bien la constitution et la fonctionnalité du nouveau mécanisme disjoncteur pour dispositifs électroniques préconisé.From the previous description and representations of the attached sheets of drawings, it is easy to understand the constitution and the functionality of the new circuit breaker mechanism for electronic devices recommended.
