Definitions

  • the present invention relates to a housing for housing an electrical device such a circuit breaker and comprising, at at least one of its ends, compartments for terminal in which are respectively housed connection pads and means of fixing of said pads to external conductors such as a bar, a cable etc.
  • connection to cables via terminals we know indeed the connection to cables via terminals, the connection to bars or the connection of the "disconnectable" type to a fixed rigid conductor.
  • switching from one connection method to another requires the use of different parts.
  • One of the solutions used consists in mounting the screws in metal "clips" or insulating plates removably attached to the connection pads. After mounting the bars on the screws, they are retained on the connection areas by nuts. On the other hand, for connection to power cables, such immobilization of the screws is not necessary.
  • the isolation distances are ensured either by a cover screwed under the device (in the case of the use of a clip), or by an appropriate shape and dimensions of the aforementioned plate, when it this is used.
  • the present invention provides an electrical appliance box of simple design, allowing to make different types of connection using a minimum of parts.
  • the present invention relates to a housing of the kind previously mentioned, characterized in that the means for fixing the pads to the conductors comprise, for at least one of the above-mentioned compartments at least one first opening provided in the housing, at least one second opening provided in the connection area and located (s) opposite the first opening (s), and at least one screw passing through two openings facing the housing and the range to ensure the fixing of a conductor on the connection pad, said first opening being shaped on the one hand, to receive and guide in rotation at least one screw head of circular shape and on the other hand, to block in rotation relative to the housing at least one screw head of suitable shape not circular.
  • the circular head screws are intended to the fixing of terminals on the connection area.
  • the aforementioned non-circular head screws are intended for fixing bars on the connection pads.
  • the or each first opening is also adapted to receive a fixed rigid conductor.
  • the or each first opening forms at least one housing substantially hexagonal cooperating with at least one screw whose head is substantially the same shape.
  • these compartments 2 are intended to accommodate terminals 4 for connecting the aforementioned areas 3 to power cables 5.
  • These terminals 4 are constituted by blocks 6 fixed on the pads 3 by means of screws 7 introduced from the rear of the housing 1, through two openings 8, 16 respectively first and second provided respectively in the housing 1 and in the range 3, before screwing into one of the ends of the corresponding terminal 4.
  • each compartment 2 of the housing 1 is associated with an opening 8, said first, formed in the rear part of the housing 1 and allowing the passage of two terminal fixing screws 4.
  • This opening 8 forms two housings 8a, 8b, of substantially hexagonal shape, connected by a rectilinear part 8c.
  • These two housings 8a, 8b are shaped so as to each receive and allow the free rotation of a round head screw 9, 10 and with a hollow recess used for fixing a terminal 4.
  • connection pads 3 are each connected to a bar 23.
  • the bar fixing screws 23 need to be immobilized in rotation.
  • screws having a hexagonal head 11, 12 are used, which, when introduced into the openings 8, are immobilized in rotation by the walls delimiting the portions of openings 8a, 8b of hexagonal shape.
  • the pads 3 are connected in the disconnectable mode.
  • the openings 8 provided in the housing 1 are intended to receive each the free end 13a of a fixed connection pin 13, the shape of which corresponds to that of the opening 8.
  • Each of the openings 8 provided in the housing 1 is closed by an insulating cover 19 hingedly connected to said housing 1 by a hinge 14 integrated into said cover 19.
  • This hinge is fixed to the housing by a clip (C), allowing the cover to remain secured to the housing in the open position of said cover. Note also that at when closing, the cover is closed with another clip.
  • connection operation will be described briefly below according to the type of connection chosen.
  • connection type of the disconnectable type is chosen, the device D is moved in direction of fixed conductors in the form of pins 13 so as to introduce the end 13a of said pins 13 inside the openings 8 of the housing 1.
  • the fixing of the pins 13 on tracks 3 is effected by means of a screw 17 inserted from the front of the devices D through the two orifices 16, 8 provided respectively in the range 3 and the housing 1 and screwed into the corresponding end 13a of the pins 13.
  • Each rigid conductor or pin 13 has one end 13a comprising two columns 18, 19 of section substantially hexagonal connected by a cross member 20 and each comprising an orifice 21 of fixing intended to receive said screw 17, said end 13a cooperating with a first opening 8 of corresponding shape of the housing 1.
  • this housing further comprises a reinforcement piece 24 inserted into each first opening, which has a cross section slightly enlarged compared to the openings of the previous embodiment, so to improve the resistance of the housing to the maintenance of the screws.
  • this reinforcing piece 24 is removable so as to allow, when this is extracted from the housing, the housing of a fixed rigid conductor of section slightly enlarged.
  • the hexagonal shape of the housings and the screw heads is only given as example.
  • Other shapes for the housings and the screw heads could of course be envisaged in the context of the invention provided that they allow the blocking of these screws in rotation and that they allow the free rotation of circular head screws.
  • the screws used will advantageously be standardized screws.
  • the different electrical isolation distances are provided by the cover.
  • the connection by bar is carried out in a simple way, only one tool being necessary for tighten. Note also the possibility of changing the standardized screws by others (more or less long).
  • the housing of the device fulfills several functions, namely, the support of the ranges of connection, the isolation of the phases between them, and with the outside, the rotation resistance of the bar connection screw, cover screw fixing function, screw maintenance before and during installation of the device, compliance with the electrical isolation distances through the cover.
