Definitions

  • the known adapters are bulky and expensive, which limits their possibility of use.
  • the present invention aims to remedy these drawbacks, and to allow the production of a compact adapter with a reduced number of parts and assembly work.
  • the arrangement in three layers of the constituent elements of the adapter allows a limitation of the electrical and mechanical connections.
  • the electronic card advantageously carries a printed circuit connecting the components carried by the card and this printed circuit is connected to the power circuit during the soldering of connections of parts belonging to the power circuit. This arrangement allows the production of sub-assemblies, the final assembly of which is particularly simple and rapid.
  • the differential fault detector is preferably of high sensitivity causing tripping for earth fault currents, for example equal to or less than 30 mA.
  • the plastic adapter housing is constituted by a base 10, forming the rear face and covered by a cover 12, carrying the front face 14.
  • the base 10 carries on the rear face, a cylindrical collar 16 protruding, crossed by pins 18 and an earth contact 20, constituting a standard plug with earth connection capable of being plugged into a conjugated wall socket.
  • the front face 14 of the cover 12 includes a flange socket 22, the bottom of which is pierced by two orifices 24 giving access to two sockets 26.
  • a ground plug 28 projects inside the flange 22, the assembly constituting a socket with standard female plug.
  • the sockets 26 are aligned with the pins 18 and in the working position the adapter is plugged into a wall socket and receives a plug from a user appliance plugged into the canister 22.
  • the plug 18, 20 and the plug 26 , 28 can of course be of a different type.
  • the first electromechanical sub-assembly 30 is constituted by a polarized relay 38 capable of triggering in the event of an earth fault or lack of voltage, a mechanism 40 comprising a finger 42 passing through a wall 43 of separation sub-assemblies 30, 32.
  • the sub-assembly 32 is a sliding contact switch 44, cooperating with two pairs of fixed contacts 46 and actuated by the finger 42 of the mechanism 40.
  • the fixed contacts 46 are extended by lugs attachment 48 passing through holes in the bottom of an insulating support 50 forming a partition separating the sub-assemblies 32, 34.
  • the fixing lugs 48 pass through holes 52 m swam on the electronic card 36.
  • the tabs 48 and the orifices 52 have a rectangular section and the fixing of the contacts 46 on the card 36 is carried out in a manner well known to specialists by twisting the end of the tab 48 projecting from the card 36.
  • On the card 36 are also fixed the sockets 26, a toroid 54 of a differential transformer as well as various electronic components 56.
  • the electrical power circuit of the adapter consists of the two pins 18, two conductors 58 connecting pads 60 of the pins 18 to two fixed contacts 46 and two conductors 62 connecting the opposite fixed contacts 46 to the sockets 26 passing through the toroid orifice 54. It is easy to see that in the open position of the movable contact bridge switch 44, the power circuit is interrupted. In the closed position of this switch, electrical continuity is ensured between the pins 18 and the sockets 26.
  • the earth contact 20 is electrically connected to the earth pin or plug 28 by a fixing screw 63.
  • the toroid 54 carries a winding secondary supplying a trip signal, in the event of a differential fault, to the polarized relay 38.
  • the signal delivered by the secondary winding is processed and possibly amplified by an electronic circuit carried by the electronic card 36.
  • the electronic circuit of the card 36 is of the printed circuit type 64 facilitating the production and mounting of the electronic card 36.
  • the printed circuit 64 is connected to the power circuit at the level of the lugs 48 of the fixed contacts 46, the connection being made during welding of the end of the conductors 58 to the lugs 48.
  • a control lever 66 is housed in a cell 68 of the front face 14 and cooperates with the control mechanism 40 to open, close or reset this mechanism.
  • a test button 70 simulating a differential fault to verify the proper functioning of the adapter.
  • a window 72 formed in the bottom of the cell 68 opposite a lamp 74, allows an indication of the commissioning of the adapter.
