Definitions

  • the invention relates to a supply box for the pipes of electrical distribution systems, these being of the type comprising a metal conduit of generally rectangular and elongated cross section, inside which conductive bars are held by means of insulators, connections can be made on these bars using appropriate junction boxes.
  • the object of the present invention is to provide a power supply box of the type specified above which can be used indifferently to the right and to the left, without there being any fear of connection errors, and avoiding delicate handling.
  • the invention provides a supply box capable of being mounted on the two ends of an electrical distribution pipe of the type comprising a rigid or semi-rigid tubular conduit containing a plurality of axial conductive elements arranged in the same configuration at least at both ends of the pipe, these conductive elements each having, according to its position in said configuration, a functionality distinct from that of the other conductive elements, said box comprising connection devices arranged in the above configuration, so as to be able to couple on said conductors at one or other of the ends of the pipe, these connection devices each comprising means for connection to a flexible conductor of a supply cable, this connection having to perform in such a way that each flexible conductor has the same functionality as the conductive element to which it comes to connect.
  • this supply box is more particularly characterized in that it comprises means for identifying functionality comprising a moving part carrying two series of identification symbols and provided with coding means, this part being mobile between two lockable positions, namely: a first position in which the keying means can come into engagement with keying means integral with one of the ends of the pipe, so as to allow the coupling of the connection devices on said elements conductors, and a second position in which the polarizing means can cooperate with corresponding keying means integral with the second end of the pipe, so as to allow, at this second end, the coupling of the connection devices on said conductive elements, the identification symbols being arranged so that, for each of the two aforementioned positions of the part, they indicate the functionalities of the flexible conductors which must be connected to the aforementioned connection means.
  • the keying means according to the invention make it possible to prohibit the connection of the supply box to one end of the pipe if the moving part is not in the correct position, and therefore if the functionalities which must have the flexible conductors to be connected to the connection means are not correctly indicated.
  • the coding means in question comprise at least one lug secured to the movable part according to the invention, this lug cooperating with a recess or a correspondingly shaped notch secured to the pipe.
  • the device advantageously comprises two lugs, which improves the positioning of the assembly and increases its mechanical strength, and these lugs preferably have oblique ramps facilitating their insertion into the corresponding recesses.
  • the power supply box according to the invention comprises a housing in which the moving part is mounted, the polarizing means projecting for their part out of this housing, while the moving part can be fixed to this housing by means of at least one screw passing through an elongated transverse lumen.
  • At least one of these screws is screwed from inside the housing of the power supply box. Thanks to this arrangement, and especially if this inner screw is placed under the passage of one of the conductors, the risks of oversights and errors are even more limited, since their unscrewing is essential for moving the mobile part, which almost necessarily involves disconnecting the conductors.
  • the selection of the above identification symbols is carried out by means of corresponding windows provided in the housing in locations such that it is only possible to read in one of the above positions of the moving part the symbols to be used in this position.
  • the supply box of the invention is preferably mounted on the pipe by means of a splint which is provided with first keying means ensuring its correct positioning on each of the ends of the pipe and second means of coding intended to cooperate with the coding means provided in the identification means equipping the box.
  • the reference 1 designates a conventional pipe for the distribution of electrical energy, of the kind that is commonly encountered in factories and workshops.
  • a pipe comprises a rigid metal conduit, of generally rectangular and elongated cross section, inside which conductive bars are mounted by means of insulators, connections which can be obtained on these bars by means of suitable boxes, the l one has been shown diagrammatically in 2.
  • the bars in question here include a neutral N and three lines L1 to L3.
  • the supply of electrical energy is brought to the right or to the left by a supply box 3 also comprising connection devices D arranged so as to couple on the conductors N, L1, L2, L3.
  • Each of these devices comprises means of connection R to a flexible conductor C of a supply cable.
  • the same type of feed box can be used on the right and on the left.
  • the box in question, 4 is provided with coding means which; to facilitate the explanations, are represented diagrammatically on the right-hand part of FIG. 2 by a lug 5 which is formed on a movable part 6 of the supply box 4 and which cooperates with an external facing recess 7 formed on a splint 8 mounted at the end of line 1.
  • the part 6 is movable, transversely relative to the conductors, between a connection or connection position shown in solid lines in FIG. 2 where the lug 5 can penetrate into the recess 7, and a position symmetrical with respect to to the longitudinal axis XX ′ of the system which is indicated in broken lines and where this penetration is impossible.
  • the longitudinal position of the conductors in the splint 8 and in the supply box 4 is such that they cannot touch each other in this second connection prohibition position, even if an attempt is made to do so.
  • the movable part 6 of the supply box 4 can be locked in each of these two positions by means which will be examined below.
  • the splint 8 has at its other end a recess 7 ′ which is for example symmetrical with the recess 7, and therefore located at the same distance as it from the axis XX ′ of the system, and which is not used se for the right connection of Figure 2. It is provided on the other hand of keying notches 9 which oblige to always mount it in the same direction on the pipe 1, the recesses 7 and 7 ′ being for example always at- above its axis XX ′ in the embodiment shown.
  • the feed box 4 comprising a housing 10 in which is mounted the movable part 6, the latter can take, by transverse translation according to the arrows F, two positions shown respectively in solid lines and in broken lines and corresponding respectively to the connection on the right and on the left.
  • the current supply conductors have also been designated, by N, L1, L2 and L3, and the joint 8 has not been shown.
  • the lug 5 is here replaced by two lugs 11 and 11 ′ which are in one piece with the movable part 6 and which are movable with the latter between two symmetrical positions with respect to the axis XX ′ of the system .
  • the ribs 8, not shown, also have two recesses 7 or 7 ′ of corresponding shape and position.
  • the pins 11 and 11 ′ are advantageously provided with oblique lateral ramps which facilitate their introduction into the associated recesses.
  • the lateral sliding of the mobile part 6 is ensured by four transverse slots 12 to 15 respectively traversed by screws 12 ′ to 15 ′ which are screwed into the housing 10 and which, tightened fully, allow the mobile part 6 to be blocked, and therefore pins 11 and 11 ′, relative to the housing 10.
  • the two screws 12 ′ and 13 ′ are blocked from the bottom of the housing 10, their heads resting on the latter, while the other two, 14 ′ and 15 ′, are screwed from inside the housing 10 under the passage of the neutral conductor N and one of the lines L1 to L3.
  • Their unscrewing is essential to move the movable part 6 from one position to another, this almost necessarily involves the reversal of the conductors, and further limits the risk of forgetting.
  • part of the moving part 6 extends against the underside of the housing 10 which has four windows 16. It carries a label 17 on which are printed two identical, but inverted, series of indications N, L1, L2, L3, these writings being arranged in such a way that, depending on the position of the movable part 6, it is one or the other of these series which appears in the windows 16, and this, in the appropriate direction, which makes the nature and position of the various connected conductors perfectly visible and identifiable.
