Definitions

  • the invention relates to an electrical safety socket whose powering up of the conductive pads of the socket is delayed until the complete introduction of a connection plug.
  • the object of the invention is a socket receiving ordinary connection plugs, the plugs of the socket being normally not connected to the voltage source and automatically switched on during the simple and complete introduction of the connection plug. in the socket.
  • Another object of the invention is a socket of this kind, the tensioning of the studs being established, after introduction of the connection plug only when the latter conforms to well-defined standards.
  • One of these standards may notably be the presence on the plug of a socket normally connected to the ground of the device to which the plug is connected.
  • this socket being fitted with a grounding pin, and that the plug does not have a corresponding socket so that the If the plug cannot be inserted into the socket sockets, the user cannot obtain any voltage even by electrically connecting the socket sockets with any device. plug to the pins of its socket.
  • Another object of the invention is a socket of this kind in which the means for controlling the tensioning of the socket sockets is a means which meets the standards adopted, controlling the tensioning only after complete insertion of the pins of the connection plug in sockets.
  • any risk of sparking between plugs and sockets is eliminated and, in addition, the electrical switching, automatically controlled after the plugs are fully inserted, can be accomplished by any safety anti-spark device incorporated in the catch.
  • Another object of the invention is to avoid, after switching on the plugs of the plug, any risk of sparking as a result of a faulty contact between plug and socket by the presence of any device incorporated in the socket ensuring contact straightforward between socket and pin, in particular by means of a ball contact.
  • Another object of the invention is a socket of this type according to which the electrical contact between the plug and socket of the socket is established only after a determined stroke of the pins in the housing of the sockets, this contact being followed the triggering of the tensioning of the plugs of the socket only by the complete insertion of the connection plug into the socket.
  • the wall outlet designated by the general reference 1 in FIG. 1 essentially comprises studs such as 2 and 3 electrically connected to the tension wires 4 and 5 via the switching devices 6 and 7.
  • These switching devices are preferably safety devices without producing a spark and are fixed in the embodiment shown by the screws 12 and 13. These devices can optionally be housed inside compartments formed by the walls 14 provided on the base 15 of the socket.
  • the switches 6 and 7 are controlled by means of their control lugs 16 and 17 which may be in any form suitable for their common control member consisting of a sliding part 18 comprising an axial passage for the passage of the spindle. earth 20.
  • This part more visible in Figures 2 and 3, slides in a cylindrical housing 19 in the middle part of the socket. It slides axially around the earth pin 20 between the position it occupies in FIG. 2 when it is only stressed by the spring 21 and the position that it occupies in FIG. 3 when the connection plug 30 is pressed.
  • the spring 21 is supported between the flat and bent end of the conductive part 22, which is more visible in FIG. 1, serving to fix the ground pin 20, and an annular part 23 inside the part 18.
  • the latter pushed back by the spring 21, bears on the wall 24 of the socket.
  • the wall 24 comprises a central orifice allowing the cylindrical end 18a of the sliding part 18 to pass around the spindle 20. In this position the control pins 16 and 17 of the switches 6 and 7 are not pushed back by the conical part 18b of the Exhibit 18. These pins are normally biased in this position permanently prohibit any connection between the tension lines 4,5 and the pads 2,3 do not the plug.
  • the fastener 22 of the pin 20 is fixed to the base by means of the screw 25, bearing on appropriate flanges of walls molded with the base 15.
  • the end of the part 22 is electrically connected by the screw 26 to the wire. of earth 27.
  • the fixing piece 22 and the pin 20 can be made integral by any means, and form only one and the same piece.
  • the pads 2,3 in electrical contact with the outputs 10,11 of the switches 6,7 can take any desired shape to transmit the voltage to the sockets proper 28,29 receiving the pins 31,32 of the plug 30, the pads 2,3 are preferably conductive strips attached to the corresponding sockets 28,29, each equipped with a contact ball.
  • the contact ball biased by a spring bears laterally on the pin which is introduced into the socket. In this way the socket can receive any kind of plug, the dimensions can vary from one plug to another in a predetermined area.
  • FIG. 4 shows by way of example a stud 2 electrically connected to the socket 28 which, in addition to the usual cylindrical part, comprises a ball 33 urged by. the spring 34 and the pusher 35.
  • a cylindrical housing 36 opening into the cylindrical part of the sleeve 28 by a conical part serves as a guide for the pusher 35 and the spring 34, the smallest section of the conical part guiding and retaining the ball 33
  • any pin 32 inserted in the socket 28 laterally pushes the ball 33 while ensuring a frank contact even in spite of any possible vibration.
  • Insulation blocks 37 and 38 have been placed between the sockets 28, 29 and the switches 6, 7, these blocks being shaped to allow passage to pins 31 and 32. It should be noted that these switches can be of any type including mercury switches which are toggled by the control panel 18.
  • cylindrical part 18a can be replaced by any desired shape and be accessible only by a part of the plug acting as a key in a lock constituted by a passage giving access to the part 18.
  • the part 18 may even in the rest position not cover the exposed part of the earth pin.
  • the invention also applies to sockets of which a single socket or pin is thus isolated from the line of tension which corresponds to it.
  • the das on Ja sheet has a part serving as a key, this may be shorter than its pins.
