FR2811858A1 - Telecommunications container wall attachment method having rib structured base wall with unit wall attached using screws rib groove passing and adjacent rib internal face attached. - Google Patents

Abstract

The container has a base wall (11) with rib structure (13,14) and forming grooves. The ribs provide a solid mounting on a base wall. The unit is attached to the base wall using screws which pass into the grooves in the ribs and screwing into the internal faces of adjacent rib sections.

Description

The present invention relates to a box intended to accommodate organs

electrical

  of liaison or control, in particular communication equipment, and

  nant a bottom in insulating material coming from molding.

  Boxes used to house equipment and provide telecommunication links

  nication require easy and quick mounting of boxes, terminal blocks or connectors

necessary for this purpose.

  The boxes currently available on the market need to be improved by

this point of view.

  The object of the invention is therefore to facilitate, by simple arrangements produced from the molding of the box, the mounting of the members in the box and the assembly of the box.

  According to the invention, the bottom wall has pairs of ribs forming each

  cun a groove, and the pairs of ribs determine a mounting frame integral with the bottom wall and preferably formed by two crossed networks of pairs of ribs oriented at an angle; each member is capable of being fixed to the bottom wall of the box by means of at least one screw inserted in a groove

  and engaged by its thread against the internal faces of the facing ribs.

  The pairs of ribs are preferably obtained by molding with the bottom wall. The box may advantageously have, at the corners of its lateral walls, slots in the form of slots, as well as a cover having at the corners elastic fixing tongues cooperating with the slots, the slots and the tongues being oriented at an angle and situated at the four angles of the side walls and respectively of the cover. The slots can be arranged so that

  debate elastically and be provided, as well as the tongues, with transverse streaks

  dirty in the direction of insertion of the tongue into the slot.

  In addition, the side walls of the box may have grooves directed perpendicular to the bottom wall and designed to receive by interlocking

  beads of flat union pieces capable of joining two adjacent boxes.

  The description will be made below of a non-limiting embodiment of

  the invention, with reference to the accompanying drawings.

  Figure 1 shows in front elevation a box according to the invention, without its cover.

  Figure 2 is a side view of the cover of the box.

  Figure 3 shows schematically in exploded section the bottom wall and the

tage of an organ on this wall.

  Figure 4 is a partial perspective view of an angle of a box and its

assembly to a neighboring box.

  The box 10 shown is made of molded plastic and has a wall of

  bottom 11 and four side walls 12. The bottom wall 11 has a certain name.

  bre of pairs of ribs 13,14 each forming a groove 15. It is advisable to

  wait that the ribs 13,14 come from molding with the bottom wall and constitute

  kill two oblique and crossed rows, so as to determine an inclined frame

  born of assembly for various organs for example with communication function

  tion. As the members have fixing holes aligned horizontally or verti-

  wedging, the inclination for example at 45 of the rows of coupled ribs 13, 14 increases the mounting flexibility. The inclination can of course be different. The bottom wall also offers knock-out openings 16 or provided with plugs

  for the passage of fasteners or cables.

  The members A are fixed to the bottom wall using screws 17 of the self-tapping type (see FIG. 3) capable of engaging by their threads and of being maintained in the

  facing internal faces 13a, 14a of the groove or ribs 13,14.

  The side walls 12 are provided at the corners of the box and towards the front with slots 18

  biased; to the slots are adjoining neighboring recesses 19, these recesses

  intended to give the slots a possibility of deformation or deformation

  beat. The slots serve as housings for tabs 21 provided at the four corners of a flat cover 20 removably attached to the rest of the box. The

  legs are also inclined with respect to the vertical and the horizontal. The confi-

  guration of the legs allows, by means of a weakened part 22, their displacement or elastic deformation. The legs have, on a face 23 located for example

  outwards, grooves 24 which cooperate with a corresponding internal surface

  dante, also ribbed, of the respective slot 18. It is understood that the cover can thus be fixed reliably to the box by compensating for deformations or

differences in ratings.

  The box can be fixed to a rear support or be flooded. As seen in Figure 4, boxes adjacent to each other can be assembled using parts

  union plates 30 whose edges 31 are constituted by beads which interlock

  tent in grooves 32 located in the side walls 12, especially near the

corners of the box.
