Definitions

  • the present invention generally relates to the safety of electrical installations.
  • connection terminals are enclosed in a closed space at the rear of the housing and, thanks to the shutter, they are not accessible from the front as long as 'an electrical plug is not plugged into the well of the hubcap mounted in the front space of said housing.
  • a power outlet complies with the IP4X safety standard even if the bezel is not mounted in the front space of the housing since the shutter is positioned in the rear space of this housing closed by said intermediate wall.
  • the earthing yoke has an additional function since part of its base, positioned adequately in the enclosed space provided at the rear of the housing, forms a guide element which guides the shutter during its translation movement between its shutter and release positions.
  • front and rear will be used in relation to the direction of the user's gaze turned towards the electrical outlet mounted in the wall. So, the front of an element will designate the side of that element that faces the user, and the back will designate the opposite side.
  • THE figures 1 to 10 represent a power socket 10 according to a standard with side earth contacts.
  • This power socket 10 includes an insertion well 12 ( figure 1 ) adapted to receive an electrical plug for the electrical connection of this electrical plug to an electrical network.
  • the power socket 10 is intended to be mounted in an equipment support (not shown) itself intended to be positioned either in a recessed electrical box or attached projecting from any wall, or in a trunking.
  • this power socket could be an extension type socket, or be part of a multiple socket block, without the principle of the invention being modified.
  • the power socket 10 comprises a mechanism 100 comprising an insulating housing 110 housing electrical elements and a hubcap 200 attached to the housing 110.
  • the hubcap 200 forms the insertion well 12 of the power socket 10.
  • the well The insertion 12 here presents an axis X for engaging the corresponding electrical plug (visible on the figure 1 ).
  • the housing 110 is made of molded plastic material. Here it has a generally parallelepiped shape which has an interior space open towards the front.
  • the housing 110 has a bottom 111 bordered by a side wall 112 which delimits the interior space.
  • the side wall 112 has four sides, two by two opposite each other, which rise from the bottom 111, substantially perpendicular to it.
  • Wall lateral 112 has a free peripheral front edge 115 which delimits the front opening of the housing 110.
  • the housing 110 houses a cover 120, made of insulating material, which forms an intermediate wall dividing the interior space of the housing 110 into two parts: a front part 110A and a rear part 110B.
  • the rear part 110B is a closed space which extends between the bottom 111 of the housing 110 and said cover 120 (see figures 7 to 9 ) while the front part 110A is an open space which extends between the cover 120 and the front opening of the housing 110.
  • the cover 120 is formed by a plate whose generally flat front face 120A extends substantially parallel to the bottom 111 of the housing 110.
  • the cover 120 comprises fixing means intended to cooperate with complementary fixing means of the housing 110.
  • the cover 120 carries on three adjacent sides tabs provided with anti-tearing teeth 122 adapted to hang on edges 114 provided in the side wall 112.
  • the cover 120 rests on arrangements (not visible in the figures) formed in the side wall 112 of the housing 110 in such a way that it closes the section of the interior space of the housing 110.
  • the rear part 110B of the housing 110 houses the electrical contact elements of the power socket 10. These electrical elements include three connection terminals 130A, 130B: a phase terminal 130A, a neutral terminal 130A and an earth terminal 130B ( Figure 5 ). Each of the connection terminals 130A, 130B must be supplied with current via a conductor coming from the network.
  • each of the phase and neutral terminals 130A is an automatic connection terminal with a contact leaf spring 131 and a socket 132 for receiving a pin of an electrical plug plugged into the power socket.
  • the terminal terminal 130B is also an automatic leaf spring contact connection terminal 131.
  • the cells 132 are located opposite two circular orifices 125 provided in the cover 120 for the passage of the pins of the corresponding electrical plug.
  • the pins of this electrical plug pass through the orifices 125 of the cover 120 and enter the cells 132 of the phase and neutral terminals 130A.
  • connection terminals 130A, 130B There are provided, in a rear part of the side wall 112 of the housing 110, openings (not visible in the figures) in which disconnection levers 135 are engaged by which we can act on the contact spring blades 131 of the connection terminals 130A, 130B to release the stripped core of the electrical conductors connected to said connection terminals 130A, 130B.
  • the power socket 10 shown on the figures 1 to 10 is a power outlet according to a standard with side earth contacts, in which earthing is carried out via a yoke 150 of metallic material connected to said earth terminal 130B.
  • the lyre 150 is conventionally obtained by cutting and folding a metal strip. It comprises a base 151 in the form of a flat strip which connects two symmetrical connection branches 152 ( figures 1 to 7, 9 and 10 ).
  • the base 151 of the yoke 150 has a parallel front face 151A and a rear face 151B.
  • connection branches 152 forms an angle less than 90 degrees relative to the base 151 ( figures 1 , 3 to 5, 9 and 10 ).
  • Each of the connection branches 152 has a substantially 5-shaped shape which is connected to the base 151 of the yoke 150 by a part curved towards the center of the power socket. In this way the connection branches 152 of the yoke 150 are capable of slightly deforming elastically to come into contact with the corresponding metal part of the electrical plug plugged into the insertion well 12 of the power socket 10.
  • connection branches 152 of the yoke 150 emerge in the insertion well 12 of the power socket 10.
  • the shape of the connection branches 152 towards the side wall 112 of the housing 110 allows their support against complementary contact zones of the electrical plug when it is inserted into the socket 10.
  • the base 151 of the yoke 150 is arranged in the rear space 110B of the interior space of the housing 110 in a space between the cover 120 and the connection terminals 130A.
  • the base 151 of the yoke 150 is arranged under the cover 120, in a space located between the two orifices 125 of the cover 120 and above the connection terminals 130A.
  • the cover 120 has, in a central part, an opening 126 intended to accommodate the base 151 of the yoke 150 so as to position the yoke 150 centrally in the housing 110.
  • the base 151 of the yoke 150 is pressed against part of the rear face of the cover 120 by filling this opening 126.
  • part of the base 151 of the yoke 150 appears through the opening 126.
  • the base 151 of the yoke 150 is sandwiched between an interior arrangement of the housing 110 and the rear face of the head of a stud 160 coming from the housing 110 (see figures 2 and 9 ).
  • the base 151 of the lyre 150 comprises an opening 151C positioned substantially in the center of this base 151.
  • the slotted head of the stud 160 passes through the opening 151C of the base 151 of the yoke 150, to cooperate by snap-fastening with a bar 127 belonging to the cover 120 so that the rear face of the head of the stud 160 rests against the front face 151A of the base 151 of the yoke 150 while a central part of the rear face 151B of the base 151 of the yoke 150 rests against said interior arrangements of the housing 110 (see Figure 9 ).
  • This bar 127 extends to the center of the opening 126 of the cover 120 ( figures 2 to 4 , 6 and 9 ) from one longitudinal edge to the other of this opening 126.
  • the bar 127 is formed, projecting, at the front of the cover 120.

  • the yoke 150 is also held in the side wall 112 because the curved part of each connection branch 152 which connects to the base 151, is engaged in a groove 118 formed in the thickness of the side wall 112 and rests on the bottom 117 of this groove 118 (see figures 2 And 3 ).
  • the edges of the grooves 118 hold said connection branches 152 laterally, the bottom of the grooves 118 holds the yoke 150 rearwardly.
  • the joining of the base 151 of the yoke 150 to the cover 120 makes it possible to raise the yoke 150 as much as possible in the housing 110 and therefore to save space in the rear part 110B of the housing 110 for the positioning of the connection terminals 130A, 130B in this housing 110.
  • the housing 110 houses a shutter 170 which, in a rest position, closes said orifices 125 of the cover 120.
  • this shutter 170 is positioned in the rear part 110B of the interior space of the housing 110, between the cover 120 and the connection terminals 130A, 130B. More precisely, the shutter 170 is arranged between the base 151 of the yoke 150 and the entrances of the cells 132 of the phase and neutral terminals 130A.
  • This shutter 170 is mounted freely in translation between a closing position (its rest position) in which it closes said orifices 125 of the cover 120 and a release position in which it frees the passage through these orifices 125.
  • the movement of translation of the shutter 170 between its shutter position and its release position is carried out by inserting through the orifices 125 of the cover 120 the pins of an electrical plug plugged into the insertion well 12 of the socket. current 10.
  • This translation movement is carried out against an elastic return means 180 which permanently pushes the shutter 170 into its shutter position.
  • This elastic return means is a helical spring 180 compressed between the shutter 170 and an interior part of the housing 110.
  • the shutter 170 has a U shape whose two branches 172 form shutters for closing the orifices 125 of the cover 120.
  • the two branches 172 are interposed between the orifices 125 of the cover 120 and the inputs of cells 132 of phase and neutral terminals 130A (see the Figure 6 ).
  • the shutter 170 is made in one piece by molding an insulating plastic material.

  • the base 171 of the shutter 170 comprises a groove 171A shaped to accommodate a part of the base 151 of the yoke 150. Thanks to this cooperation between the groove 171A of the base 171 of the shutter 170 and the part of the base 151 of the yoke 150, the shutter 170 is perfectly guided in translation between its shutter and release positions without it being necessary to provide additional arrangements in the box 110.
  • the arrangement of the yoke 150 and the shutter 170, as close as possible to the cover 120, allows, while maintaining the electrical safety of the power socket 10, to have a larger space in the part rear 110B of the housing 110 for positioning the connection terminals 130A, 130B in this housing 110.
  • the housing 110 includes arrangements 119 ( Figure 10 ) forming a stop means for the shutter 170, making it possible to block the translation of the shutter 170 in the shutter position (during its translation movement to close the orifices 125).

  • the electrical plug is then free to penetrate deeper into the power socket 10, until its pins engage in the sockets 132 of the phase and neutral terminals 130A to be connected to these terminals.
  • connection branches 152 of the yoke 150 Concomitantly, during the insertion movement of the electrical plug, the metal earth parts of the electric plug come into contact with the connection branches 152 of the yoke 150 to be connected to the earth terminal 130B of the power outlet 10.
  • the electrical plug causes the elastic deformation of the connection branches 152 whose ends 153 engage in the cutouts 206B of the cylindrical wall 202.
  • the extraction of the electrical plug from the power socket 10 causes the reverse movement of the different components of this power socket 10, thanks in particular to the different return means involved.
  • the shutter 170 remains attached to the housing 110. Due to this connection, the shutter 170 makes it possible to ensure the electrical safety of the power outlet 10, even when the hubcap 200 is dismantled. The shutter 170 thus retains its role of electrical protection when the hubcap 200 is removed from the housing 110. The other shutter 230 remains attached to the hubcap 200, which facilitates the dismantling of the latter.
