Description

Bypass booth for electrical conduits.

  The subject of the present invention is a trash box.

  for electrical conduits.

  For the connection of conduits intended to receive electrical conductors, it is known to use housings in which the connections are protected relative to the external environment. These housings consist of a body and a cover and they comprise a means for connecting the conduits

said housings.

  In a known embodiment, the body is connected to ducts provided with connectors having a nozzle provided with an annular groove in which are engaged the edges of openings

  or indentations in the side walls of the body.

  However, in this arrangement, the tip presents

  two walls of quadrangular shape which allow only one

  duct in two perpendicular directions.

  According to the present invention, the body

  near the edges of the opening, a position

  nement likely to be engaged in a complementary member provided on the periphery of one of the walls defining the annular groove of the tip, said members provided on the body and on the tip

  constituting an angular indexing means of the duct on the casing.

  This arrangement makes it possible to orient the conduit

  a greater number of positions and virtually any position. Other features and advantages of the invention

  will be better understood by reading the following description

  several embodiments and with reference to the accompanying drawings, in which:

  FIG. 1 is a plan view of an embodiment of

  the boot according to the invention; - Figure 2 is a side view of the box according to the arrow II of Figure 1; - Figure 3 is a side view of the box along the arrow III of Figure 1; FIG. 4 is a half-sectional side view of the disassembled body and cover; - Figure 5 is a top view of the body; the lid being disassembled; - Figure 6 is a sectional side view of the casing disassembled with the tip of a conduit; - Figure 7 is a sectional view along the line VII-VII of Figure 5; - Figure 8 is a side view of another embodiment of the boot according to the invention; - Figure 9 is another side view of the casing shown in Figure 8; FIG. 10 is a side view of the body and

boot lid disassembled.

  In FIGS. 1 to 7, there is shown a trash box

  which comprises a body 1 closed by a cover 2 and on which are connected conduits 3 intended to receive internally

electrical conductors.

  Each duct 3 is provided with a coupling comprising a nozzle 4 having an annular groove 5 delimited by two walls 4a, 4b, said groove being intended to engage the edges 6, 6a of openings 7 formed in the side walls 8 body 1 of the box. The openings 7 which open near the upper edge of the casing in the manner of notches have two parallel edges 6, 6a and a bottom delimited by a semicircular edge 9 which matches the bottom of the groove 5, as well as a notch circular 10

  (Figures 4, 5) is provided on the edge of the lid 2.

  Outside the casing 1 body, near the edge of the openings 7, there is provided a positioning pin 11 which is engaged selectively in one of the notches 12 provided in the

  outer wall 4b delimiting the annular groove 5. This arrangement

  sition makes it possible to carry out an orientation of the duct according to a large number of angular positions which are determined by the number

  notches 12 provided on the connector end.

  The fixing of the lid 2 on the body 1 is carried out by means of two fastening members 13, 13a, each of which has a stud 14 engaged in an orifice of the lid 2 against which the head 15 of the fastener bears, said stud 14 having a slot 16 in which is engaged a rod 17 which

  is disposed in a housing 18 formed in the body 1 to receive

  see said pin 14 in the closed position of the lid. The head 15 of the fasteners 13, 13a has holes 19 which are aligned when the fasteners are in the closed position, so that a rod 20a of a pin 20 is likely to be engaged in said holes 19 of the two fasteners 13, 13a. Inside the body 1 of the casing are provided tubular members 21 integral with the bottom of the body 1 and

  which are arranged coaxially with holes 22 provided in the neck.

  vircle 2 for the passage of screw rods for fixing the casing. 14 'inside the body 1 of the case, the lid 2 and the

  fittings and their end piece 4 are coated with a layer of

  lytetrafluoroethylene or any other product to ensure an anti-abrasive and insulating function in contact with the electrical conductors. In Figures 8, 9 and 10, there is shown another embodiment in which the orientation means are different

  and consist of polygonal housing 23, particularly

  hexagonal, in which are engaged the edges of corresponding polygonal shape provided on the outer wall 24 of the

  end caps 25, said wall 24 delimiting with another parallel wall

  inner lobe an annular groove similar to the groove 5 of

Figure 6.

  The dwellings 23 are arranged around the part

  semicircular 9 openings or notches 7 of the casing body.

  Of course, the description is not limiting and

  those skilled in the art may make various modifications to it without

as far out of his frame.
