Definitions

  • the invention relates to an insulating base and a device electrical connection equipped with such a base.
  • a bar system can be used to power, at using conductive cables, an energy use site electrical such as housing, industrial premises, building or subdivision.
  • a connection device electric can be used in a connection cabinet and, for example, in a current distribution cabinet between several dwellings located in a housing estate or a street, or several apartments in a building.
  • a wardrobe of distribution may include a connection device to bars as described in FR-A-2-715 775.
  • the bars of a system with bars are arranged parallel to each other on storied pedestals being covered by covers leaving free of access areas located at the bars, in order to allow the connection of connectors themselves connected to the end of conducting cables.
  • the number of modules used depends on the length of the bars which itself depends on the number of connectors to plug into these bars.
  • the modular nature of the device known allows to adapt its total width to the use desired by juxtaposing modules formed by bases fitted of caches. Given this modular nature, the bars receiving housing which are defined between the bases and covers must allow the positioning of a cross bar on several modules. Therefore, these housings are provided open at the level of the passage of the bars on the sides of the modules and covers.
  • an insulating base for a connection device as mentioned above which comprises, at level of at least one of its edges up to the vicinity of which extends a space for receiving a bar, at least one elastic insulating tongue, deformable between a first configuration where it separates this reception space from the exterior and a second configuration where it is free relative to this space.
  • the deformable tongue which remains permanently in place on the base, isolates a bar present in the receiving volume from the outside by defect, this tab being erased or released relative to this housing when a bar passes from this base to a base neighbor, that is to say in an intermediate part of a connection device.
  • the tongue As the tongue remains in placed on the base, it fulfills its function by default insulation and is not likely to be forgotten or improperly positioned by an operator.
  • the invention also relates to a connection device electric between a busbar and several cables conductors, these bars extending parallel to each other others in reception spaces formed by at least one insulating base and at least one insulating cover, this cover defining connection areas to these bars, this connection being characterized in that the base is such that previously described.
  • the cover is equipped with at least one flap, movable between a first position where it isolates from the outside a connection area to a bar and a second position where it allows access to this connection area.
  • this shutter is equipped with a locking member by cooperation of shapes in the first position, this member being worn by a tab formed in one piece with the flap.
  • This locking member guarantees that the flap folded back in its first position is not likely to be opened in a non intentional.
  • this tab extends from a branch of part of the sectional shutter U-shaped, this part being elastically deformable by pinching in a direction tending to bring its branches, the concavity of this U-shaped section part being oriented towards the base.
  • This embodiment of the organ of locking implies the need for a conscious maneuver of the U-shaped part, i.e. its pinching, to release the locking member relative to the base or to the support, i.e. allow access to the bar.
  • the flap carries a identification mark for the length of the conductor to be connected to the bar at the aforementioned area.
  • This area facilitates the work of an operator who knows immediately how long to cut a conductor so that his development is sufficient and so that he does not undergo deformation stress once the connector team connected on the bar.
  • the flap is formed in one piece with the cover and connected to it by a bi-stable hinge.
  • the monobloc character guarantees the impermeability of the shutter while the bi-stable character of the hinge allows the flap to be held in the released position by relative to the connection area, so that it does not interfere with a connector when connected.
  • the flap is articulated on the cover by a bi-stable hinge.
  • the electrical connection device shown in the figures comprises four bars 1 to 4 arranged parallel to an axis XX 'on bases 5, 5' and 5 "made of an insulating plastic material. These bases have a width l 5 of the order of 100 mm and, in the case of example where bars of length equal to approximately 300 mm are used, three bases are juxtaposed.
  • Each base is intended to be covered by a cover insulation 6, 6 'or 6' 'provided to insulate the bars 1 to 4 of the exterior in order to avoid any risk of short circuit and / or electrocution.
  • a base 5 or equivalent and a cover 6 or equivalent together form a module for positioning the bars 1 to 4 and cable connection.
  • the base 5 is stepped and defines four housings 51, 52, 53 and 54 used respectively for the reception of one of the bars 1 to 4.
  • Each housing is generally shaped rectangular and its largest dimension is parallel to the axis XX '.
  • the housings 51 to 54 define, with the cover 6, reception and isolation spaces for bars 1 to 4.
  • Each bar 1 to 4 is provided with holes 1 a , 1 b , 2 a , 2 b , 3 a , 3 b or 4 a , 4 b for receiving screws belonging to connectors 101, 102, 103, 104 represented in lines mixed in Figure 1 and respectively connected to the end of conductive cables 111, 112, 113 and 114 shown in broken lines by their respective main axes.
  • Each bar 1 to 4 is pierced with several orifices 1 d to 4 d for the passage of fixing screws 7, shown only in FIG. 3, and intended to penetrate into threads 51 d to 54 d provided in the center of each housing 51 to 54.
  • the bases 5, 5 'and 5''form housings 51 b , 52 b , 53 b and 54 b for receiving the screws of the connectors 101 and 104, each housing 51 b , 52 b , 53 b and 54 b being fitted with a nut 8 at the pitch of the screws in question.
  • the nut 8 can be molded or immobilized by cooperation of shapes in the corresponding housing.
  • the housings 51 to 54 of each base 5 or equivalent extend over substantially the entire width of the base up to the level of the lateral edges 5 a and 5 b of this base.
  • each housing 51 to 54 is equipped, near the edges 5 a and 5 b of the base, with an elastic tongue 56 extending the bottom surface 51 a , 52 a , 53 a or 54 a of the housing considered. More specifically, each elastic tongue comprises a first section 56 a extending the surface 51 a to 54 a that it adjoins and a second section 56 b generally perpendicular to the first section 56 a .
  • the bar 1 is interrupted at a certain distance d from the external lateral surface 5 c of the base 5.
  • the geometry of the tongue 56 is such that its second section 56 b extends opposite the end surface 1 c of the bar 1, so that the bar is isolated from an opening 61 provided between the cover 6 and the base 5 for the passage of the bar 1 when this base and this cover are used in an intermediate part or on the opposite side of the device.
  • the tongue 56 therefore makes it possible to avoid accidental access to the surface l c through the opening 61.
  • the tongues 56 disposed at the level of the housings 52 to 53 near the edge 5b of the module 5 make it possible to isolate the bars 2 to 4 with respect to openings 62 to 64 equivalent to the opening 61.
  • the bar 1 extends between the housing 51 and the corresponding housing 51' of the module 5 '.
  • the tabs 56 and 56 'respectively bordering the housing 51 near the edge 5 a and the housing 51' on the side of the base 5 are deformed by the bar 1 bearing on the surface 51 a and the corresponding surface 51 ' a of the housing 51 ', so that they do not oppose the correct positioning of the bar 1, without having to be dismantled relative to the base 5 and 5'.
  • Each cover 6 is equipped with five flaps, 81 to 85 for cover 6, 81 'to 85' for cover 6 ', 81 "to 85' 'for cover 6 ". These flaps allow to selectively cover openings 71 to 74 in the covers 6, 6 'or 6' ' to access bars 1 to 4 for the connection of connectors 101 to 104.
  • Each flap is in one piece with the cover to which it belongs by being connected to it by a bi-stable hinge 86 more particularly visible for the shutter 82 "aux Figures 4 and 5.
  • the bi-stable character of the hinge 86 which includes a curved tab 86a, ensures that each flap is effectively held in the closed position when should not access the corresponding bar, but also in the open position, without hindering the installation of a connector when such an installation must occur.
  • Each flap comprises, at its edge opposite the hinge 86, a U-shaped part 87 whose concavity is oriented in the direction of the corresponding base.
  • the part 87 comprises two branches or panels 87 a and 87 b extending over the width of the shutter considered and connected by an elastically deformable zone 87 c .
  • From a median zone of the branch 87 b extends a tongue 88 provided with a head 89 in the form of a half-harpoon defined by a surface 89 a inclined with respect to the tongue 88 and a surface 89b generally perpendicular to this tongue, the surface 89 b being intended to cooperate with a retaining surface 90 formed in the lower part of the base 5, 5 'or 5 ".
  • the surface 90 could be provided on a fixed part of the cover 6, 6' or 6 ".
  • the head 89 retains the part 87 and the flap in position, as shown in FIG. 4.
  • the flap When it is necessary to lift the flap, for example the flap 82 ", it suffices to exert on the part 87 a pinching force represented by the arrows F 1 in FIG. 4 to release the surface 89 b relative to the surface 90 and allow the flap to tilt, as represented by the arrow F 2 in FIG. 5.
  • the hinge 86 contributes to releasing the flap relative to the bar.
  • each component carries a 92 mark allowing an operator to determine the length to cut each cable 111 to 114 or equivalent, before fitting a connector 101 to 104 or equivalent on the end of a cable.
  • each 6, 6 'or 6 "cover is equipped with two flaps 84, 85, 84 ', 85', 84 “, 85” at bar 4 which is the neutral bar, which is materialized by the fact the flaps have the letter N on their upper side.
  • the fact that two access zones to the bar are provided in each module 5, 6 or equivalent makes it possible to envisage a single-phase connection between one of the bars 1, 2 or 3 and bar 4 in each half-module. When a connection in three-phase is performed, only one connection area on the bar 4 is used for the module considered.
