Definitions

  • the subject of the invention is, as its statement indicates, a regulator of the flow of current for electrotechnical devices having the function of limiting the passage of electric current in electrotechnical devices so that, if an increase in the intensity of the current which would exceed the limit or the critical point previously established, the triggering and consequently the actuation of the electrotechnical mechanism takes place, in the direction of opening of the established electrical circuit, thus avoiding the deterioration of the device or the electrical installation protected by the electrotechnical device.
  • the regulator for the electric current is formed by an adjustment rod which, at one of its ends, has a head in the form of a toothed wheel and, at the other end, begins a cut or diametrical groove which extends longitudinally to the proximity of the opposite end in the form of a toothed wheel; a spring which, by one end, is introduced and remains fixed in the longitudinal groove or cut of the adjustment rod, and its other end is extended in a straight branch and perpendicular to said rod; a box, provided in the carcass or body of the electrotechnical device, in which is housed the adjustment rod and the spring which it comprises, in this box is immobilized or blocked the rod-spring assembly, once the critical point has been established, or electric current limit; an extension, with end flange, of the movable or displaceable part of the electromagnet core which protrudes outside of it; and the other fixed part of the electromagnet core, with axial perforation in which is arranged a rod with thickening at one end which remains outside
  • Figure 1 shows, in perspective, the parts that form the current flow regulator for recommended electrotechnical devices.
  • Figure 2 shows, in plan and partial section, the entire regulator.
  • the current flow regulator for electrotechnical devices comprises a rod -1- which, at one end, widens in the form of a toothed wheel -2-, and at its end opposite a cutout or diametrical groove -3-, extending longitudinally to the proximity of the head -2-.
  • This rod -1- is connected to a spring -4-, which, by one end -5- remains retained in the groove -3-, while the turns of the spring -4- are wound on the rod -1- or , in other words, the rod -1- is threaded into the spring -4- after one of its ends -5- is arranged in the groove -3-, the other end of the spring -4- extending in a branch -6- straight and perpendicular to the stem -1-.
  • the rod -1- and spring -4- assembly is housed in a box -7- provided between the two parts forming the carcass or body which comprises the mechanism of the electrotechnical device, said box forming a hollow with toothed wall -16- in which is housed the toothed wheel head -2-, so that when this head -2- is controlled to set the critical trigger point, once established, it is introduced into this recess -16-, with what its subsequent manipulation is avoided.
  • the core of the electromagnet is divided into two cylindrical parts -8- and --- 9- the first of which is movable in the direction of longitudinal displacement, and one of its bases is axially extended by a stud -10- which ends in an end flange -11- on which rests the right end branch -6- of the spring --- 4- threaded by the regulating rod -1-, so that said end branch -6- prevents displacement of the part of the mobile core, as long as it does not exceed the limit or the critical point established by the regulator.
  • the fixed part -9- of the core of the electromagnet has, at one of its bases, an extension -12- also cylindrical, with axial perforation -13- right through which a rod is arranged --14 - with head -15-, which acts as striker of the actuating mechanism, for opening the electrical circuit of the electrotechnical device set.
