Definitions

  • the present invention generally relates to the embedding of electrical equipment inside various walls.
  • an electrical box comprising an insulating body which comprises a side wall closed at the rear by a bottom wall to define an interior receiving volume of at least one electrical equipment mechanism.
  • the invention finds a particularly advantageous application in the production of an electrical box recess for hollow partition, intended to receive various mechanisms of electrical equipment such as a switch mechanism, back and forth, dimmer electrical socket, socket, network jack (RJ45), phone jack (RJ11), indicator, or sensor (smoke, flood, temperature, movement or light).
  • a switch mechanism back and forth
  • dimmer electrical socket socket
  • socket network jack
  • RJ11 phone jack
  • indicator or sensor
  • the bodies of the electrical boxes comprise, internally, means for securing an equipment support, and, externally, fastening means to the wall.
  • the equipment support makes it possible to mount any type of equipment mechanism in the interior volume of the body of the electrical box, by simple snapping of this equipment mechanism on the equipment support.
  • the bodies of the known electrical boxes are usually provided at the rear with knock-out covers which make it possible to locally open the wall of the body to introduce into its internal volume electrical conductors necessary for serving the gearing mechanism attached to the support. fitting.
  • the bodies of these electrical boxes have standardized sizes.
  • the body of a circular recessed electrical box of a first standard has a diameter of 68 millimeters and a depth of 40 millimeters.
  • the solution currently used to house large electrical equipment then consists of providing two electrical boxes next to each other and to distribute the functions in these two boxes.

  • the present invention proposes a new electrical box which does not require introducing the electrical conductors into the interior volume of the body of the electrical box in order to connect the fitting mechanism. to the local power grid.
  • the electrical conductors are connected to the outside of the body of the electrical box and they do not fit inside of it, so that the entire interior volume of this body can be used to house large electrical equipment.
  • Wiring operations are also easier to implement, since they are no longer performed in or in the immediate vicinity of inside the body, but instead they are made outside the body.
  • each electrical conductor is connected to an external terminal by means of a lever which is dedicated thereto.
  • the orientation of the pivot axis of the lever, transverse to the bottom wall of the body of the box (that is to say orthogonal to it or inclined relative thereto) also has several advantages .
  • the first advantage is that the lever can have a reduced thickness, insofar as the bending forces to which it is subjected to connect or disconnect the electrical conductors are located in a plane parallel to the bottom wall of the body of the box. In this way, since the total depth of the electrical box is standardized and is therefore limited, the presence of the lever at the rear of the body of the box reduces only slightly the internal volume of the body of the box.
  • the second advantage is that, since the lever has a reduced thickness, it is possible to provide that it has a significant length, so as to increase the lever arm. The effort to exert on this lever during the connection operation or disconnection of the electrical conductor is then low, which facilitates this operation.
  • the third advantage is that, during this connection or disconnection operation, the lever is located next to the electrical conductor, so that it leaves the latter visible so that the user can visually control the state of the connection.
  • said lateral wall extending around a mean axis, said pivot axis has an angle of inclination with respect to said mean axis which is between 0 and 30 degrees.
  • pivot axis will be orthogonal to the local area of the bottom wall that it passes through and which carries the lever.

  • This bottom wall 12 has a flange 17 which rises from its rear face, on only part of its surface (delimited between the circular edge of the bottom wall and a rope of an arc of this circle).
  • This flange thus has a convex face which extends in the extension of the side wall 11 and a flat face which is turned towards the axis A1.
  • the insulating body 10 has a peripheral rim 13 which runs externally on the front edge of its side wall 11 and which is adapted to bear against the front face of the plasterboard, while around the circular opening.

  • the insulating body 10 For its restraint forward, the insulating body 10 comprises attachment means 18.
  • These attachment means 18 here comprise two bending tabs 18A which are cut in the side wall 11 of the insulating body 10 and which each bear on their outer faces a snap tooth 18B.
  • the two bending tabs 18A are located diametrically opposite to the axis A1, and extend in length from the front edge of the side wall 11 of the insulating body 10 towards the rear.

  • Each ratchet tooth 18B has a flat front face orthogonal to the axis A1, which is adapted to hook to the rear face of the corresponding plasterboard, and a rear face inclined relative to the axis A1, which form a ramp allowing the flexure tab 18A to deform elastically inwardly when the insulating body 10 is engaged in the circular opening made in the plasterboard.
  • the electrical box 1 comprises fixing means which are here in the form of two rectangular windows 19 cut in the side wall 11 of the insulating body 10.

  • This outer terminal 32 has a hollow slot 33 which allows it to pierce an insulator.
  • This slot 33 more precisely has a V-shaped mouthpiece whose two lateral edges are sharpened so as to cut the insulating sheath of the phase wire 3.
  • the bottom of this slot 33 is itself rectangular, with two straight edges that are also sharp, which are adapted to come into contact with the conducting core of the phase wire 3 in order to establish a connection between the first terminal 31 and the phase wire 3.
  • a rear housing 90 generally made of horseshoe shape.

It is also externally equipped with securing means to the insulating body 10, which are here in the form of lateral tabs (not visible in the figures) adapted to snap into latching lugs 21 provided with a protruding projection. the rear face of the bottom wall 12 of the insulating body 10 (see figure 3 ).
  • the two levers 60, 70 are symmetrical with respect to each other. Only the lever 60 provided for connecting the phase wire 3 to the phase connector 30 will then be described here, with reference to the figure 3 .

  • phase wire 3 is therefore intended to be engaged and then locked on the lever 60 in a position where it passes through the ring 66 of this lever 60.
  • the stud 15 on which the lever 60 is snapped is then split transversely by a groove 16 for the passage of the phase wire 3 (see FIG. figure 3 ).
  • This groove 16 is flared at its two ends, to allow the phase wire 3 to deform curvedly during the pivoting of the lever 60 (see figures 7 and 8 ), so that this pivoting does not create a break angle on the phase wire 3.
  • the lever 60 is movable between a disengaged position (see figures 1 and 7 ) in which the passage channel 61 and the phase wire 3 are located remote from the outer terminal 32 of the phase connector 30, and an engaged position (see figures 2 and 8 ) in which the passage channel 61 is partly traversed by this outer terminal 32 which can thus come to connect to the phase wire 3.
  • this lever 60 is adapted to push the phase wire 3 between the cutting edges of the V-mouth of the outer terminal 32 of the phase connector 30, in favor of the pivoting of the lever 60 towards its engaged position, which has the effect of cutting off its insulating sheath and connecting its conductive core to the phase connector 30.
  • the outer terminal 32 of the phase connector 30 is arcuate around the pivot axis A6. It is here curved with a diameter between that of the ring 66 and that of the first plate 67. Therefore, when the lever 60 is folded into the engaged position, the outer terminal 32 of the phase connector 30 engages between this ring 66 and this first plate 67.

  • the curvature of the outer terminal 32 of the phase connector 30 makes it possible to ensure that, during the entire travel of the lever 60, the zone of the outer terminal 32 on which the phase wire 3 is engaged remains oriented at at right angles to this phase wire 3. In this way, the insulating sheath of the phase wire 3 is not only cut cleanly when it engages the outer terminal 32, but it is also not torn off by the following.
  • each slot 66A, 67A provided in the ring 66 and in the first plate 67 allows, when the lever 60 is folded into the engaged position, to push the phase wire 3 against the outer terminal 32 of the connector of phase 30.

  • These locking means are here in the form of a rod 14 which rises orthogonally from the rear face of the bottom wall 12 of the insulating body 10.
  • the lever 60 comprises in correspondence, recessed in the inner lateral edge of its plate 65 (that turned towards the axis A1), a notch 69 adapted to engage transversely on the rod 64 when the lever 60 arrives in the engaged position .
  • This notch 69 has a flared mouth to facilitate the docking of the rod 14, and a narrowing width that allows the lever 60 to snap on the rod 14.

  • this operating portion 63 (that located opposite the ring 66) is located at a distance from the pivot axis A6 which is greater than or equal to the distance between the outer terminal 32 of the pivot axis A6. This distance is preferably strictly greater than the distance separating the outer terminal 32 from the pivot axis A6. In this way, when the user exerts a force on the free end of this operating portion 63, this force is multiplied by a lever arm effect, which allows the phase wire 3 to be connected to the outer terminal 32 exerting on the maneuvering portion 63 a restricted effort.
  • the earth connector 50 which appears on the figure 1 , is not in fact the subject of the present invention and will not be described in detail.
  • This earth connector 50 forms the first terminal to which the electrical equipment housed in the electrical box can be connected, while the tab forms the outer terminal 52 to which the grounding wire 5 can connect.
