  DETAILED DESCRIPTION OF AN EXEMPLARY EMBODIMENT

  The dispensing casing 10 completely illustrated in FIG. 1 comprises a base 11, shown more particularly in FIGS. 2 and 5, and a cover 12, shown more particularly in FIGS. 10 to 12.

  The envelope 10 is adapted to accommodate four circuit breaker devices, such as the single-phase circuit breaker 13 shown in FIG. 2 in a position where it is placed on the base 11 of the envelope 10.

  The circuit breaker 13 will now be described more particularly, with reference to FIGS. 3 and 4.

  The circuit breaker 13 has a generally parallelepipedal shape. It has two main faces 14 and 15 and, extending from one to the other of the main faces 14 and 15, side faces 16 to 19, respectively a front face 16, an upper face 17, a rear face 18 and a lower face 19.

  The front face 16 is provided with a control member, here a lever 20. A status indicator 21 is also provided on the front face 16, to indicate whether or not the circuit breaker 13 is in the tripped state.

  The circuit breaker 13 is of the plug-in type, that is to say of the type that automatically connects to a current contact when it is placed in an envelope.

  To allow its mechanical fixing and electrical connection, the circuit breaker 13 has, on the one hand, a hook 22 located at the corner where the rear face 18 and the lower face 19 meet, and, on the other hand, an elastic clamp ( not visible in the drawings), section S2, open towards the rear face 18, adapted to receive by insertion a flat contact, which can access the elastic clip through a slot 23 formed in the corner where meet the upper face 17 and the back 18.

  The elastic clamp to which the slit 23 gives access serves both to mechanically immobilize the circuit breaker 13 and to effect the electrical connection thereof with a current arrival contact.

  For the current start, the circuit breaker 13 has a screw terminal (not visible in the drawings) to which access an opening 24 formed in the lower face 19. To allow the operation of the screw of the terminal 2885457 7 which gives access the opening 24, there is provided an access conduit for a screwdriver, this conduit opening through an opening 25 in the corner where the lower face 19 and the front face 16 meet.

  The base 11 is designed to accommodate four single-phase circuit breakers such as the circuit breaker 13.

  At each receiving location, the base 11 comprises, as can be seen more particularly in FIG. 2, a mounting lug 30, on which the hook 22 engages, and a current arrival contact 31, on which engages the elastic gripper to which slot 23 gives access.

  The four contacts 31 belong to the same phase connector 32, which will be described in more detail later in support of FIGS. 5 and 6.

  It will be noted simply at this stage that the connector 32 is designed to be connected to a phase-in cable and that it therefore distributes the phase pole to the four circuit-breakers such as the circuit-breaker 13 installed in the base 11.

  To distribute the neutral pole, a screw terminal block 33 is provided at five connection points (one incoming cable and four starting cables). Similarly, to distribute the earth pole, there is provided a screw terminal 34 at five connection points (a cable arrival and four cables).

  We will now describe in more detail the base 11 in support of Figure 5.

  The base 11 comprises a base 35, the neutral terminal block 33, the earth terminal block 34, the phase connector 32, a screw terminal 36 and a connector cap 37.

  In general, the base 35, and more generally the base 11 and the casing 10, is provided to be mounted projecting on a support wall.

  The base 35 is a single piece of molded insulating plastic.

  It has a bottom wall 36 having a generally oval contour.

  In the wall 36 are formed oblong openings 37 for passage of the rod of a fixing screw on the support wall. Through the bottom wall 36, there are also openings 38 for the passage of electrical cables running in recessed conduits inside the support wall, in this case three incoming cables. (Neutral, phase and earth poles) and up to twelve start cables (one per pole for each of the four divisional circuits such as a lighting circuit or a socket circuit).

  Two detachable covers 39 project from the bottom wall 36 at the periphery thereof. When the cover 12 is in place on the base 11, each cover 39 is housed in a notch 40 of the cover 12 (see Figures 1 and 10).

  When the cables to be connected inside the casing 10 walk in a chute projecting from the support wall, this chute is connected to the location of a cap 39 and is detached therefrom. allow the passage of the cables inside the envelope 10.

  For positioning and fixing the cover 12, the base 35 has two beads 41 and four flexible snap tabs 42, the beads 41 and tabs 42 projecting from the bottom wall 36 near its periphery.

  At each location where a cut-out apparatus is to be received, the bottom wall 36 has a boss 43 having an inclined upper surface 44 whose slope line is oriented in the same direction as the larger diameter of the wall 36, the surface 44 rising towards the periphery of the wall 36.

  Each boss 43 is delimited laterally by two triangular surfaces 45 oriented in the same direction as the largest diameter of the wall 36 and a rectangular surface 46 oriented transversely, that is to say oriented in the same direction as the smallest wall diameter 36.

  The surface 44 is generally rectangular with a length (dimension measured in the same direction as the smallest diameter of the wall 36) corresponding to the height of the circuit breaker 13 (distance separating the faces 17 and 19) and with a width (dimension measured according to the same direction as the largest diameter of the bottom wall 36) less than the depth of the circuit breaker 13 (distance between the faces 16 and 18).

  Each boss 43 is lined, on the internal side, that is to say on the side where it is the lowest, by a wall 47 protruding transversely from the bottom wall 36 and having a height slightly greater than the thickness of the circuit breaker 13 (distance separating the faces 14 and 15).

  The bosses 43 and each of the two spaces located between two opposite walls 47 are generally arranged as a checkerboard with six boxes.

  Between the two bosses 43 located on the same side (that is to say the two bosses that we see on the right or the two bosses that we see on the left in Figure 5), is arranged a rib 48 oriented along the largest diameter of the bottom wall 36 and protruding transversely thereof.

  Each rib 48 extends from a bridge 49 joining two walls 47 aligned to an end located approximately at the end surfaces 46 of the bosses 43.

  The ribs 48 are less high than the walls 47, their height increasing from the bridge 49 and then remaining constant.

  In the vicinity of the wall 47 which is seen in the bottom left in FIG. 5, on the side of this wall which is opposed to the boss 43 which it runs along, the base 35 has, protruding from the bottom wall 36, two centering pins 50 and two latching notches 51 for mounting the neutral terminal block 33.

  Likewise, close to the wall 47 that is seen at the top left in FIG. 5 and on the side opposite to the projection 43 that it runs along, the base 35 has, projecting with respect to the bottom wall 36, two centering pins 52 and two detents 53 for mounting the earth terminal 34.

  Between the bridges 49 are arranged two latching fingers 54 projecting from the bottom wall 36. The fingers 54 serve for mounting the phase connector 32 and the connector cover 37.

  The phase connector 32, shown in isolation in FIG. 6, is made in a conductive metal strip cut and folded.

  It comprises a central section 60 generally U-shaped with a very elongated central segment 61 connected on each side to a return 62.

  On the side seen to the right, the central section 60 is connected to a wing 63 slightly inclined relative to the segment 61. The distal end of the wing 63, that is to say the end opposite the section central 60, is tapered.

  On the right side of the drawings, the central section 60 is connected to a wing 64 having a segment 65 generally oriented like the segment 61 and a segment 66 slightly inclined, the segment 65 being located between the return 62 and the segment 66.

  The segment 66 is generally shaped like the wing 63, with in particular its distal end (end opposite the central section 60) being tapered.

  In the section 65 are provided two slots 67 oriented transversely and located at a distance from one another, extending over approximately half the width of the connector 32. The portion of the segment 65 located between the two slots 67 is provided to receive the screw terminal 36 (Figure 5), which screw terminal 36 serves to effect the connection between the phase connector 32 and the phase arrival cable.

  In the segment 61 of the central section 60 are provided two orifices 68 for mounting the connector 32 on the base 35 by snapping into the fingers 54.

  When the connector 32 is in place on the base 35, the segment 61 is against the bottom wall 36, the wing 63 is against the inclined upper edge of the rib 48 that is seen on the left in the drawings, and similarly, the segment 66 is against the inclined upper edge of the rib 48 that is seen on the right.

  Each phase contact 31 is formed by one of the two corners of the wing 63 or by one of the two corners of the segment 66. The fact that the distal end of the wing 63 and the distal end of the segment 66 are tapered facilitates the introduction of the phase contact 31 in the circuit breaker device such as the circuit breaker 13.

  The inclination of the wing 63 or segment 66 corresponds to that of the surface 44 relative to the remainder of the wall 36, an inclination of the order of 9.

  The connector cover 37 is molded in one piece of insulating plastic material.

  As seen in Figures 2, 5 and 7, the connector cover 37 has a portion 70 oriented longitudinally, that is to say, parallel to the larger diameter of the bottom wall 36, for covering the connector of phase 32, and a portion oriented transversely, that is to say parallel to the smaller diameter of the bottom wall 36, serving to cover the neutral terminal block 33.

  The portion 70 has a base 72 of generally constant thickness, shaped like the phase connector 32.

  In the center of the base 72 are provided two orifices 73 (FIG. 5), arranged as the orifices 68 of the connector 32. The orifices 73 serve to mount the connector cover 37 on the base 35 by snapping onto the fingers 54.

  The end portions 74 of the base 72, which respectively cover the flange 63 and the segment 66 of the connector 32, each have a central slot 75 (FIG. 5) oriented longitudinally, which subdivides them into two tabs 76 each connected to the rest. of the base 72 by a thinned portion 77 forming a hinge.

  Each tab 76 has at its end a return 78 from the side facing towards the bottom wall 36 of the base 35.

  Each return 78 has on the inner side a tongue 79 (Figure 7).

  Each lug 76 has at its end, just before the return 78, an imprint 80 (FIG. 5) in narrow rectangular shape oriented transversely.

  When the connector cover 37 is in place on the connector 32, each return 78 is placed opposite the tapered end respectively of the wing 63 and the segment 66 while the tongue 78 is placed under this end.

  Thus, each tab 76 covers one of the four phase contacts 31 formed by the connector 32.

  To make accessible one or the other phase contacts 31, in order to set up an apparatus such as the circuit breaker 13, is engaged in the footprint 80 of the corresponding tongue 76, the tip of a small screwdriver flat blade, this screwdriver is then rotated to release the tongue 78 and the tab 76 is raised, which then pivots around the thinned area 77 forming a hinge.

  It will be noted that, in FIG. 2, to simplify the drawing, partial tearing has been carried out at the level of tabs 76.

  At the position of the screw terminal 36, the connector cover 37 has a shell 81 which covers the terminal 36, leaving of course an opening on the side where the slots 67 are made for the insertion of the cable of arrival of phase, and on the top, an opening 82 (Figure 5) access to the screw of the terminal 36.

  Near each of the orifices 73, on the outer side, protrudes from the base 72 a bracket 83 having a branch transverse to the base 72 and a branch parallel to the base 72, overhanging a respective orifice 73.

  The space surrounded by the base 72 and the brackets 83 can be used as a guide for the cables arranged in the base 11, the insertion of a cable in the guide thus formed being done by the space left free between the two brackets 83.

  For the square 83 which is seen on the right in the drawings, a part of the branch transverse to the base 72 is common to the shell 81.

  The transverse portion 71 is connected to the longitudinal portion 70 projecting laterally from the bracket 83 which is seen on the left in the drawings, and more specifically of the branch of this square which protrudes from the base 72.

  The portion 71 has, opposite the bracket 83 to which it is connected, a cheek 85 oriented longitudinally. Between the bracket 83 and the cheek 85, the portion 71 is formed by an angle 86.

  Openings are formed in the two wings of the angle 86 to allow access respectively to the receiving holes of a cable and clamping screws of the terminal block 33. In the cheek 85, a small window is formed on the side of the wall bottom 36 for housing a portion of the detent 51 located there (see Figure 2).

  The mounting lugs 30 of a circuit-breaker device such as the circuit-breaker 13 are provided, for each projection 43, at the lowest angle and closest to the periphery of the bottom wall 36.

  We will now describe more particularly, in support of Figure 8, the mounting lug 30 which is seen at the top right in Figure 2 or Figure 5, it being understood that the other mounting lugs 30 present the same conformation.

  The tab 30 comprises an angle 90, a wall 91 disposed between the angle 90 and the wall 47, and a tooth 92 disposed on the angle 90.

  The wall 91 is oriented in the longitudinal direction. It projects generally transversely of the wall 47 and the bottom wall 36. The bracket 90 has two wings 93 and 94.

  The wing 93 is oriented in the transverse direction. It runs transversely transversally from one end of the wall 91 and the boss 43 of the bottom wall 36.

  The wing 94 is oriented in the longitudinal direction. It projects generally transversely from the end of the flange 93 opposite the wall 91 and from the boss 43 of the bottom wall 36.

  The tooth 92 is oriented in the transverse direction. It runs generally transversely of the wing 94 and is located in the extension of the wing 93.

  The angle 90 and the wall 91 have the same height. The tooth 92 is centered, in the direction of the height, with respect to the wing 94. The surface of the flange 94 bordering the tooth 92 is in the shape of a U of approximately constant thickness.

  On the wall 47, there is provided facing the angle 90 and the tooth 92, a boss 95 whose surface facing the angle 90 and the tooth 92 rises progressively relative to the remainder of the wall 47 from the wall 36 following a relatively gentle slope.

  The angle 90 and the tooth 92 are oriented perpendicular to the surface 44 of the boss 43 and are therefore slightly inclined relative to the wall 47: here, where the surface 44 has an inclination of the order of 9 relative to the rest of the bottom wall 36, the angle 90 and the tooth 92 are inclined relative to the wall 47 at an angle of the order of 9.

  As can be seen in FIGS. 3 and 4, the circuit breaker 13 has, in front of the hook 22, a groove 96 formed over the entire thickness of the circuit breaker 13, that is to say from the face 14 to the The depth of the groove 96 (distance measured in the back-to-front direction) corresponds to the width of the flange 94 (distance separating the face 97 facing the boss 95 and the opposite face 98) while the height of the groove 96 (dimension measured in the bashaut direction) corresponds to the width of the flange 93 (distance separating the face 99 of the wall 91 situated on the side where the angle 90 joins the face 100 of the flange 94 bordering tooth 92).

  The minimum distance between the boss 95 and the angle 90, and more precisely between the face 97 and the face of the boss 95 facing the angle 90, where it is minimal (at the top of the tab 30) corresponds at the depth of the hook 22 (distance measured in the back-to-front direction).

  Thus, when the circuit breaker 13 is in place on the lug 30, as can be seen in FIG. 9, the angle 90 is housed in the groove 96 while the hook 22 is housed in the space delimited by lacornière. 90, the wall 91 and the boss 95.

  Inside the circuit breaker 13, there is provided a recess (not visible in the drawings), opening into the groove 96, to accommodate the tooth 92.

  It will be observed that the slight inclination of the circuit breaker device such as the circuit breaker 13 provided by the boss 43 and by the corresponding inclination of the mounting lug 30 and the contacts 31 allows the front face 16 to be slightly longer. away from the rest of the bottom wall 36, which facilitates in particular the operation of the lever 20 and allows to see what is the position of the lever and the state of the indicator 21 without having to approach too much of the support wall on which is mounted the base 11.

  It should be noted that the circuit breaker 13 is of a smaller thickness than the conventional circuit breakers of the plug-in type by tilting a hook around a mounting lug and by inserting a contact into an elastic clamp located at inside the housing of the device which is accessed by a slot. Thus, the typical thickness of pluggable devices of this type is 1 inch (25.14 mm), while the thickness of the circuit breaker 13 is only 3/4 inch (19.05 mm).

  It should also be noted that in prior conventional pluggable devices there is no groove such that the groove 96 extends over the entire thickness of the apparatus (from one major face to the other).

  Since the phase contacts 31 are all located in the central position of the base 11, the two circuit breaker devices such as the circuit breaker 13 installed on the same side of the base 11 (side that is seen to the right or side that we see on the left) are arranged so that the position of one corresponds to the mirror image of the position of the other.

  Thus, while in conventional envelopes the circuit breakers such as the circuit breaker 13 are arranged upright and side by side, that is to say with the face 19 at the bottom and the face 17 at the top, in the base 11, the Apparatuses are laid down and, for those who are arranged on the bosses 43 that are seen at the top in the drawings, in the upside down position, that is to say with the face 17 which is at the bottom and the face 19 which is at the top.

  In order to facilitate the reading of the position of the lever 20, reference marks 105 are provided on the bottom wall 36.

  To enable easy identification of which circuit corresponds which circuit-breaker device, there are provided near each reference mark 105 ribs 106.

  As explained above, the base 35 of the base 11 comprises, to cooperate with the cover 12, two beads 41 and four detent tabs 42.

  It is also provided ribs 107 projecting from the bottom wall 36 at the corner where are connected the faces 16 and 19 of the circuit breaker device such as the circuit breaker 13 and ribs 108 near the location where the corner where the faces 16 and 17 meet.

  As seen more particularly in FIG. 10, the cover 12 comprises a body 110 and two doors 111.

  The body 110 has the same contour as the base 35 between two planes passing, respectively, by the surfaces 46 of the two bosses 43 on the left and by the surfaces 46 of the two bosses 43 on the right.

  Thus, it is the body 110 which has the notches 40 and the tabs 112 (FIG. 11) provided to cooperate with the detent notches 42.

  At each location where the front face of a circuit breaker such as the circuit breaker 13 is to come, the body 110 has a detachable lobe 113.

  Between two lobes 113, there is provided a non-detachable arch 114. The grooves 108 provided on the base 35 serve to receive the end of the side walls 115 of the arch 114 and a right transverse wall 116 located at the junction between the arch 114 and the remainder of the body 110 (see Figure 11).

  On the side of each lobe 113 opposite to the arch 114, there is provided an angled wall 117 which is housed in the grooves 107 of the base 35.

  Each door 111 has a curved wall 120 of complementary shape to that of the body 110 and protruding from the wall 120, two arms 121 each oriented in the longitudinal direction and each carrying, on the outer side, a hinge pin 122 (Figure 12 ).

  The body 110 has, on the outer side of each wall 117, a slot 123 allowing the passage of one of the arms 121. The pin 122 is housed in a not shown hole of a wall 124 that includes the body 110 to near the slot 123.

  Each door 111 can thus be raised by pivoting around the pin 122 to access the front face of a circuit breaker such as 13.

  In the example illustrated, the body 110 is molded from an opaque insulating plastic part while each door is molded from a piece of transparent insulating plastic.

  The transparent nature of the doors 111 makes it possible to see the state of the circuit breaker devices such as the circuit breaker 13 without having to raise the door 111.

  In a variant not shown, the envelope 10 receives a circuit breaker other than a single-phase circuit breaker such as the circuit breaker 13, for example a fuse cut-out or a differential switch.

  In other variants not shown, the inclination of the boss such as 43 is different, for example between 3 and 15; the protruding member of the mounting lug as received in the groove 96 is different from an angle, for example a bead; the arrangement of the locations for the circuit breaker devices is different, for example without symmetry according to the largest diameter of the base 35 and / or without symmetry according to the smaller diameter of the base 35; the number of receiving locations of a circuit breaker is different from four; and / or the distribution envelope is not of the housing type, but of another type, for example an array.
