  • the male sockets have protruding contacts capable of being inserted into the contacts of the wall socket, also known as a female socket, when the protective housing of the male socket is introduced into the recess in the housing. protection of the socket.
  • FR-A-2 122 316 discloses a safety socket outlet comprising a female socket arranged for example in a wall.
  • This female socket has two openings for the two terminals of a male socket as well as two electrical contacts intended to be touched by the terminals of the male part. These contacts include a switch means which closes an electrical circuit when they are mechanically actuated during the introduction of the male part into the female part.
  • Document FR-A-2 232 101 on which the preamble of claim 1 is based discloses an electrical outlet, the wall part of which has two openings for the terminals of the male part as well as a third opening for the introduction of a magnet which is on the front surface of the male part, said magnet collaborating with a movable plate which is in said third opening and which actuates, during its movement, a switch located in the electrical circuit.
  • the object of the present invention is to provide a socket system which presents absolute safety with regard to accidents following the introduction of a longitudinal metal object into any of the insertion orifices for the electrical contacts of the socket. female, during the disconnected state of the sockets.
  • the system according to the present invention eliminates the need for a switch that can be actuated from the outside while supplying power to the phase contact of the female plug following the introduction of the male plug.
  • this object is obtained by a system of sockets which is characterized in that said switch is inaccessible and cannot be activated by the introduction of an object into any opening of the female socket.
  • the switch is located inside the protective box of the socket and is connected between an electrical input conduit and a corresponding electrical contact of the socket so that said electrical input conduit is electrically separated from the electrical contact corresponding to the socket, said switch being operable to produce electrical contact between said conduit it input and socket contact by the actuating means which is located in the protective housing of the male socket when the latter is engaged in the female socket.
  • the switch consists of a Reed relay and the actuating means of a magnet, the arrangement of the Reed relay in the protective housing of the socket and that of the magnet in the housing of the male plug being such that the strength of the magnetic field of the magnet in its plugged-in position in the female plug is sufficient to activate the Reed relay and put it in a connection state in which a connection electrical connection between the inlet duct and the corresponding contact of the socket is established.
  • the socket according to the present invention may include a light indicator which is connected between the phase contact and the neutral contact, light indicator which lights up as soon as the phase contact is energized.
  • a fuse connected either between the phase contact and the phase conduit of the cable which connects the male plug with any electrical device, or between the neutral contact is also provided in a known manner. and its corresponding conduit.
  • the switch consists of at least one internal contact which can be opened and closed by means of a first movable magnet located in the socket and biased in the closing direction of the internal contact by a second magnet located in the male socket.
  • the first and second magnets are arranged in the female and male plugs respectively in a reverse manner, so that the first magnet is driven in the direction of closing of the internal contacts while moving back with respect to the male plug.
  • the socket is only energized by a retraction of the internal magnet of the socket, which ensures that the energization is carried out only by the approach of a magnet oriented opposite to that which is inside the socket and not by the approach of any ferro-magnetic object which would cause the attraction of the internal magnet of the socket whereas if the internal contacts of the socket were closed by the approach of the internal magnet rather than by its retraction, the socket could be accidentally energized when approaching any ferro-magnetic object.
  • the first magnet located inside the socket can cooperate simultaneously with two internal contacts located between the phase and neutral electrical input lines respectively.
  • the first magnet which opens and closes the internal contacts and which is driven in its movement producing the closing of the internal contacts is biased towards its position for opening the internal contacts by a spring.
  • the female socket may further comprise an externally accessible switch connected in series with the switch not accessible from the outside and / or a light indicator connected between the electrical phase contacts and neutral.
  • FIG. 1a, b and c there is shown a known safety socket in which the socket 1 has three contacts 21 which are electrically connected to three input conduits Pe, Me and Ne, according to the phase designation , mass and neutral, the index e having the meaning of entry.
  • An internal connection contact of the socket is connected with the Ne conduit and then directly with one of the contacts 21.
  • a second contact 21 is connected directly with the input ground Me, while another internal contact of the socket is connected with the input phase conduit Pe, this second internal contact being connected to the third contact 21 only by means of a switch 20, a switch which can be put in a running position and a position according to the indications M and A of figure 1a.
  • the two contacts 21 which are connected with the phase pipe Pe and the neutral pipe Ne are connected to a light indicator 12, which is lit when the switch 20 is closed.
  • FIG. 1b shows a male plug comprising the three contacts 22, one of which is connected directly with a neutral output conduit Ns, a second with the output mass Ms and a third with the output phase conduit Ps, this third contact being connected to the output phase conduit through a fuse which limits the current flowing into the plug.
  • FIG. 1c the state of connection of the male plug is illustrated inside a recess of the female plug, the switch 20 being in the on position, a position which closes the contact separating or connecting the conduit. phase input phase contact of the socket.
  • phase contact of the socket is energized and the light indicator 12 is therefore on.
  • FIG. 2a we see a socket 1 similar to that of Figure 1a having three contacts 7,8 and 9, the contact 7 being connected directly with the input ground Me while the contacts 8 and 9 are connected with the fixing contacts 5 and 6 for the phase conduit and the neutral conduit through two Reed relays 10 and 11.
  • the female socket further comprises a protective housing 3 normally placed more or less flush against a wall, protective housing which is provided with a recess 4 which is intended to receive a male socket as illustrated in FIG. 2b.
  • the male connector 2 illustrated in FIG. 2b corresponds in principle to the male connector 2 in FIG. 1b, the only difference being the presence of a magnet 18, which is arranged in the housing 4 ′ of this male plug so as to be in the proximity of the Reed relays 10 and 11 housed in the female plug following the complete introduction of the male plug into the recess 4 of the female plug .
  • FIG. 2c This state of complete insertion of the male plug into the female plug is shown in FIG. 2c.
  • the bringing together of the magnet 18 in the immediate vicinity of the Reed relays 10 and 11 causes the latter to close by the magnetic field of the magnet 18, so that an electrical connection between the fixing contacts 5 and 6 d on one side and the contacts 8 and 9 of the socket on the other side occur.
  • the contact 8 of the socket is energized, and closing the Reed relay 10 closes the circuit between the input phase conduit Pe and the neutral conduit Ne. In this way an electric current can flow between the conduit Pe and the conduit Ne as soon as the contacts 8 and 9 are connected to each other through an electrical appliance connected to the output phase conduit and to the neutral conduit Release.
  • the light indicator 12 is lit as soon as the Reed relays 10 and 11 are closed.
  • the socket 1 ′ comprises a protective housing 3′ which is closed on the wall side by a bottom 25.
  • This bottom 25 has a formation 28 d an electrically insulating material which serves as a support for the contacts 26 which are arranged one behind the other so that only one contact is seen.
  • These contacts 26 are arranged inside the protective housing 3 ′ so as to be aligned with insertion openings 24 which are provided to allow the passage of the contacts 8 ′ of the male plug 2 ′ inside the socket to create mechanical contact between the socket and the socket.
  • the female socket also includes a magnet 11′ which is oriented inversely to the magnet 18 ′ located in the male socket so that the complete approach from the male plug to the female plug during which the contact 8′of the male plug engages in the contact 26 of the female plug, produces a displacement of the magnet 11 ′ towards the bottom 25 of the socket against the force of the spring 21.
  • the contact 29 is closed and, provided that the contact 28 is closed, the contacts 26 of the socket are energized.
