Definitions

  • the object of this invention is a new circuit breaker mechanism for electrotechnical devices, primarily intended, and in a broad sense, for the formation of electromagnetothermic devices which produce the breaking or opening of electrical circuits when, in the installation in question, there are the necessary conditions determining the rupture or opening; more particularly, this mechanism itself constitutes a device for those indicated, characterized by the particular conformation of its parts which provide it with great solidity and, consequently, a longer duration compared to the mechanisms already known.
  • this new mechanism comprises means for manual actuation of the load or of the closed position of the circuit in question, which is controlled by it; and discharge or opening position means of the controlled circuit, which are set in motion when, in the installation, the conditions occur which determine for this the triggering of the movable contact on the fixed contact.
  • the new mechanism which is recommended, is essentially composed of: A manual actuation handle which is integrally extended by a drilling pad right through in its center and another eccentric drilling; a piece or rod of wire bent at its two ends in the shape of a "U" and, at the central part, a double bending, said piece making the office of connecting rod for transmission of movement of the bearing from which the controller; a ratchet part, controlled by the lever, which secures the mechanism in a charge or closed circuit position, in which the assembly maintains equilibrium, as long as none of the causes which would upset this equilibrium does not occur and, by Consequently, the opening of the circuit; a balance piece which is connected to the pawl; a mobile contact support part; a drive part which partly houses the movable contact support part; a common axis rod of the pawl part, of the movable contact support part, and of the drive part, which is fixed between the two parts forming the carcass body which houses the mechanism; four springs, one for recalling the actuating lever, another for connect
  • FIG 1 shows, in perspective, the parts that make up the new mechanism, in this illustration we can appreciate the particular conformation of each of them.
  • Figure 2 shows, in plan, the assembly and the interrelation of the whole of the new mechanism, in the open circuit position, in which the parts are kept in the rest position.
  • FIG. 3 the same assembly of the preceding figure is shown, but the mechanism arranged in the load or closed circuit position, in which the parts which compose it are kept in unstable equilibrium.
  • the new mechanism for triggering electrotechnical devices comprises: A lever -1- manual actuation, secured to a roller -2- which has one of its bases, lowered in part, with a cutout on its perimeter wall and a central bore -3- right through with a socket which surrounds it and arcuate reliefs, and a bore -4- eccentric;
  • the roller -2- comprises the spring -5-, and is connected by a rod-axis -6- integral with the carcass -7- which comprises the mechanism, so that an end branch of the spring -5- is housed in a notch of said carcass, and its other end branch exceeds the cutout of the wall surrounding the roller - -2-;
  • the eccentric drilling -4- of the roller -2- receives inside a branch end of a connecting rod piece -8-, formed by a rod or a wire bent in a "U" shape and doubly bent at its central part, and its other end branch is connected to the ratchet piece -9- .
  • the pawl piece -9- in the form of a right angle, has in its center a bore -10- through and through, which can be reinforced, on one of its faces, by a sleeve which surrounds it and, on its opposite side, it can be bypassed by a socket -11- with a larger diameter; one of the sides of this pawl piece -9- has a through hole -12- and, on the opposite side, it has a cutout or a notch determining a tooth or point -13-, by which it is connected to the piece -14- pendulum; moreover, the pawl part -9- is connected to the connecting rod -8-, and by its central part -11- it rests on the face of the socket -28- of the part -26- for supporting the movable contact -29-.
  • the pendulum piece -14- has a shape reminiscent of the silhouette of a "magpie”, with a side beak -16- for its engagement with the tooth -13- of the ratchet piece and, on its opposite side, a cylinder with almond groove -17- which crosses it; approximately at the central balance part -14- a rod -18- has been provided, plugged in by the spring -19- which has one of its end branches supported on one side of the plaice -20- of the balance -14- and, its other end branch is supported on the lateral face of the "U" cutout -39-, provided in the drive part -22-.
  • this pendulum piece -14- On its lower end this pendulum piece -14- has a right-hand drilling -23- in which is housed one end of the piece -24- formed by a rod or wire bent in a "U" shape and which, by its other end, is connected to the bimetal -25- (see figures 2 and 3), which determines the drive of the balance -14- and, consequently, its oscillation and the release of the spout -16-, of the tooth -13- , pawl - -9-, determining the imbalance of the whole mechanism which returns to its rest position or open circuit.
  • the movable contact support part -26- is elongated laminar, and has, at one end, a circular enlargement -27- with central bore surrounded by a socket - -28-, and at its other end it comprises the movable contact -29-.
  • the spring -15- plugs in the socket -28- so that at one end it is inserted into the groove in the projection -36- of the drive part -22- and its other end --- -30- remains joined to a notch - 31- provided on one side of the circular enlargement - -27- of the support piece -26- of the movable contact -29-.
  • the enlarged end -27- is housed in the drive part -22-.
  • the drive part -22- is constituted by a cylinder which conforms a notch in the center of which rises a cylindrical portion -32- from which in turn rises another cylindrical portion -33- of more diameter small with axial drilling right through, the wall -22- of this drive piece, externally has a plaice from which stands a rod -21-, which becomes the pivot axis of the pendulum -14- in s 'introducing into a borehole that the pendulum -14- has for this purpose at the bottom, concentrically with the rod -18-; and on the diametrically opposite side, a trapezoidal projection -34- which serves as a stop on a small wall -35- provided in the casing of the carcass which houses the mechanism.
  • the drive piece -22- has a grooved projection -36-, in this groove is housed the end of one of the branches of the spring -15-.
  • the part -22- On its perimeter wall the part -22- has a "U" cutout by which the support part -26- of the movable contact comes out, this part being housed on the cylindrical portion -33- of smaller diameter ; on the lower base of the part -22-, in the cylindrical notch -32- having the largest diameter, is disposed the return spring -37- which is connected by the axis rod - -38- common to the part -22-, part -26- mobile contact support, spring -15- and ratchet -9-.
  • 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.
  • 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.
