- each blade 112 has a large edge 124 shaped tenon, its large opposite edge being shaped mortise 126.
- the blades 112 are oriented so that the pin 124 of a blade is engaged in the mortise 126 of the adjacent blade.
- the tenons 124 and the mortises 126 are shaped to bind the adjacent blades to each other, while allowing a pivoting of the blades relative to each other.
- the blades 112 pivot relative to each other around the studs 124.
- the posts have, for this purpose, substantially cylindrical shapes and the mortises of the conjugate forms.

- the light 58 is thus sealed.
- the various elements of the sheath namely the base 54, the shell 56, the outlet sleeve 62 and the blades 112, are made for example essentially of thermoplastic material, for example polyamide or polybutidene terephthalate.
- the procedure for mounting the sheath 6 around the outer end 14 of the bar is as follows.
- the two half-shells 66 of the base are first placed on either side of the electrically insulating device 4. Then, the two half-shells 66 are assembled to one another by means of bolts or screw. The base 54 is then rigidly fixed to the wall P of the transformer by means of screws engaged in the tabs 72, and / or nuts.
- the two half-shells 80 and 82 of the shell 56 are then placed on either side of the end 14 of the bar. Before assembling the two half-shells to one another, the longitudinal position of the shell 56 is adjusted so that the connecting hole 17 of the connector 16 is placed in the axis of symmetry X of the light 58 .
- the lug 24 of the connector is oriented in the desired direction for the departure of the electrical conductors.
- This orientation can be, as on the figure 1 , along the longitudinal axis. It can also be substantially perpendicular to the longitudinal direction, that is to say substantially horizontally on the figure 1 .
- the orientation of the terminal 24 can also be any intermediate value between these two extreme positions, for example at 45 ° with respect to the longitudinal direction, as on the figure 2 .
- the electrical conductors are connected to the lug 24 through the light 58. Then the two half-shells 104 of the outlet sleeve are placed around the conductors and are engaged by the arcuate portions of the collar in the 118. The sleeve 62 can then be moved along the lumen 58 so as to adjust its position according to the orientation of the lug 24 and the electrical conductors.
- the blades 112 are placed in the slides 118. They are distributed on either side of the sleeve 62 adequately to wedge it to the desired position. As the blades are added, the pins 124 are engaged in the corresponding mortises 126 so as to bond the blades 112, the sleeve 62 and the straight edges of the light to one another. Finally, the half-shells 104 of the sleeve are fixed to one another by screws or bolts, and the half-shells 80 and 82 of the shell 56 are fixed to one another by bolts or screws. .
- the bar-pass assembly described above has multiple advantages.
- the sheath comprises a lumen and means for wedging the output at a plurality of possible positions in the lumen, the departure of the electrical conductors may be in different orientations corresponding to different possible positions of the output.
- the output can take many positions: ten in the illustrated example. These positions cover an angular sector of substantially 90 ° for the departure of the cables.
- the sheath has no elastic part placed under stress, and is therefore particularly durable.
- the assembly of the sheath around the outer end of the rod is easy, since the main elements of the sheath are divided into two half-shells. It is thus possible to mount the sheath around the rod after the or the electrical conductors have been connected to the same rod.
- the outlet is held in position vis-à-vis the light only by the blades, the collar being free to slide in the grooves.
- the outlet is not bound by positive attachment means to the hull.
- the blades are likely to be detached from each other, and also disengaged from the edges of the light output. They can easily be extracted from the light and replaced in an arrangement corresponding to the new desired position for the output.
- the blades and the outlet are mounted in slides, it is easy to move them in the light from one position to another.
- the sheath advantageously has means for adjusting the position of the light with respect to the lug fixing passage on the end of the bar. This ensures that the fixing passage is positioned along the axis of symmetry of the light.
- This adjustment is made very simply and economically, because the sheath is divided into two parts, a base and a shell whose position is adjustable longitudinally relative to the base.
- the sheath can be adapted easily according to the specifications of the customers, in particular according to the criteria to be respected for the angular range of adjustment of the orientation of the departures of electrical conductors, and for the finesse of this adjustment.
- the adjustment range is adjusted by adjusting the size and shape of the light.
- the fineness of adjustment that is to say the spacing of the positions likely to be adopted by the output in the light, is adjusted by varying the width of the blades.
- a second embodiment of the bar-pass assembly is illustrated on the figure 5 .
- the protective sheath 6 of the outer end 14 of the bar is rigidly fixed to the bar-pass device 4.
- the sheath 6 is not in contact with the wall P of the transformer, and is totally independent of this wall.

- the wall of the opening 96 has at its end opening inside the shell 56 a re-entrant rib 142 projecting inwardly from the opening 96.
- the rib 142 forms a shoulder against which the tube 136 abuts .
- the rib 142 internally defines a passage of restricted section, corresponding to the section of the bar 2. The end 14 of the bar is engaged in said restricted section. The rib 142 thus ensures centering and guidance of the bar at the entrance to the shell 56.
- the two half-shells 80 and 82 of the shell 56 each comprise a tab 144 substantially perpendicular to the longitudinal direction.
- the two tabs 144 pinch between them the free end 146 of the bar.
- the tabs 144 comprise complementary cutouts, of shape conjugate to that of the bar.
- the legs 144 take between them one of the small rounded sides of the bar, and part of each of the large faces of the bar. The bar is thus guided and centered at the opening 96 by the re-entrant rib 142 and at its free end 146 by the two tabs 144.
- the embodiment of the invention of the figure 5 has the advantage that there is no direct contact between the sheath 6 and the wall P of the transformer, so that there can be no current leakage from the wall P to the sheath 6.

- the shell usually has a shape adapted to the shape of the light.
- the half-shells of the base, the shell and the outlet can be fixed to each other by any means other than those described above, for example by staples.
- the different elements of the sheath may not be in two half-shells but may be in one piece.
- the blades may be bonded to each other and bonded to the outlet by means other than tenon / mortise bonds, for example staples.
- the outlet can be locked at different light positions, in addition to the blades, by positive attachment means, for example staples distributed along the light.
- the bar may not be substantially rectangular section, but rather circular section. It can be designed to be connected to a medium voltage output of the transformer and not to a low voltage output.
- the electrically insulating device interposed between the bar and the wall may be of a type different from that illustrated on the Figures 1 to 4 . It can be for example of the type illustrated on the Figures 4 to 8 of the application filed under the number FR 06 04640 .
