Definitions

  • the present invention relates to a four-pole differential switch provided with four fixed contacts and four corresponding movable contacts arranged in line and comprising a differential sensor arranged to detect a leakage current and to transmit a signal corresponding to a control device connected to said sensor, this device being coupled to a trigger mechanism for actuating a switching bar carrying the movable contacts of the switch.
  • the differential sensor is generally constituted by a toroidal winding surrounding the conductors of the electric current and the control device is a relay which supplies the triggering mechanism at the moment when the sensor transmits its signal. This occurs as soon as the sum of the currents in the supply conductors is not zero, which means that the circuit leaks to earth.
  • the tripping mechanism usually comprises a lever which releases the bar carrying the movable contacts to allow the opening of said contacts of the switch.
  • the switch bar had the same configuration for all four contacts, it would be impossible to predict the order in which the contacts of the differential switch would close when a leakage current is detected.
  • the current differential switches are designed so that the contact corresponding to neutral closes before the contacts corresponding to the phases.
  • the switching bar carrying the mobile contacts is constructed in such a way that the difference between the mobile and fixed contacts which correspond to the neutral is smaller than the differences between the contacts corresponding to the phases. In this way, at the time of tripping, it is guaranteed that the closing sequence of the contacts is indeed that which is desired, namely in the order: neutral - phase - phase - phase.
  • phase - phase - neutral - phase is also tolerated.
  • phase - phase - neutral - phase is also tolerated.
  • phase - phase - neutral - phase is prohibited: phase - phase - neutral - phase, and phase - phase - phase - neutral, because they generate compound voltages.
  • the neutral terminal is located at the left end of the four-pole switch box while in some other countries this terminal is located at the right end of the box. This requires both a separate manufacturing according to the market and a separate storage of products intended for this or that other market, and creates a risk of error for the electrician.
  • the present invention proposes to overcome these drawbacks by providing a switch of the type mentioned above which eliminates both the increase in cost of production and storage and the risk of assembly errors for the user.
  • the four-pole differential switch characterized in that said bar comprises means for reducing the difference between the movable contacts and the corresponding fixed contacts arranged at the two ends of said contact line.
  • said means comprise peripheral bulges formed on the switching bar.
  • the four-pole differential switch 10 comprises a housing 11 provided with four input terminals 12a, 12b, 12c and 12d, and four output terminals 13a, 13b, 13c and 13d.
  • the input terminals are, for example, respectively connected to fixed contacts 14a, 14b, 14c and 14d
  • the output terminals are, in this case, respectively connected to movable contacts 15a, 15b, 15c and 15d.
  • the fixed contacts are arranged on conductive elements connected respectively to the input terminals.
  • the movable contacts are mounted in a manner known per se on a switching rod 16 rotatable about its axis which is coupled to a trigger mechanism 17 also known.
  • This bar has the function of a camshaft, the movable contacts being urged to bear against these cams by means of thrust springs.
  • the geometric shape of these cams which are in the form of a peripheral bulge 18, 19 respectively, defines the distance between the movable contacts and the corresponding fixed contacts.
  • These bulges can be produced by molding or machining and are in one piece with the switching bar. They can also consist of added elements.
  • Figure 2 shows more precisely the construction and arrangement of the movable contacts 15a, 15b, 15c and 15d. It can be seen that the end contacts 15a and 15d are offset from the central contacts 15b and 15c. This offset, which generates a different difference, is due to the bulges 18 and 19 formed at the periphery of the bar 16.
  • FIG. 3 represents a fixed contact, for example 14a or 14b, and two corresponding movable contacts, for example 15a and 15b. Thanks to the bulge 19 present on the bar 16, the distance separating the contacts 14a and 15a is less than the distance separating the contacts 14b and 15b. Similarly, thanks to the bulge 18, the distance separating the contacts 14d and 15d is less than the distance separating the contacts 14c and 15c, that is to say that the distances between the contacts arranged at the two ends of the line of contacts, or at both ends of the housing, are less than the deviations of the central contacts, which makes it possible to reach the fixed objective.
