  • the strip comprises in in addition to a partitioning body of insulating material provided with means of fastening to said strip, said body comprising a rack having a sill from which partition walls extend, each space located between two consecutive partitions and in line with said sill housing the distal end of a respective one of said teeth.
  • the subdivision body thus provides for each tooth, and more generally for the quick-connect terminal to which this tooth belongs, a compartment delimited by the sill and the two partition walls surrounding this tooth, each of these compartments allowing the user to put in place and then easily control the correct disposition of each cables in the various terminals of the terminal strip.
  • connection strip comprises for each said spring a lever of maneuvering on said ruler by said backrest and resting on this spring by the face of its third section opposite to its first section; while she also has a flexible member for holding each said lever in taken on the slider and resting on the associated spring.
  • the user thus has, for each terminal with fast connection, a ready-to-use operating lever, which can be tilted for example with a simple conventional electrician screwdriver whose flat blade is engaged in an imprint of the lever provided for this purpose.
  • connection strip comprises for each said spring an operating lever engaged with said ruler by said backrest and resting on this spring by the face of its third opposite section to its first section; while it involves, to maintain each said lever thus engaged on the slide and bearing on the associated spring, a flexible openwork palisade protruding from said rack in overflow relative to said sill, from the end of the partition walls opposite said sill.
  • the invention also aims, in a second aspect, a distributor having at least one terminal strip as set out above and two flanges between which extends each said bar, which is fixed to each end to one of said flanges.
  • the splitter 1 illustrated in FIG. 1 comprises two flanges 2, four connection strips 4 and a nameplate 5.
  • the flanges 2 are made of insulating plastic on the plane electric.
  • Each flange 2 has the back (side that we see below on the 1 and 2) an indentation 8 for mounting the flange, and therefore the splitter 1, on a standard ⁇ profile rail.
  • each flange 2 has two consoles on the internal side protruding 9 vis-à-vis while in the thickness of the wall 6 is arranged a notch 10.

  • terminal strips 4 are identical.
  • connection strip 4 comprises a strip 15, a plurality of springs in ⁇ 16, here in number thirteen, a subdivision body 17 and, for each spring 16, an operating lever 18.
  • the ruler 15 is made of metallic material that is a good conductor of electricity and relatively rigid. It has a generally L-shaped profile which one of the wings forms a backsplash 20 which is constituted by a relatively narrow continuous band, while the other wing of the ruler 15, wider, forms a rake 21 having a plurality of teeth 22, here in number thirteen, that is to say that there are as many teeth 22 only springs 16.
  • the rake 21 comprises, between the backrest 20 and the teeth 22, a sole 23 here in continuous strip form.
  • Each tooth 22 is connected by a proximal end to the sole 23 and has at its distal end a rim 24 curved on the opposite side to backsplash 20, the portion of each tooth 22 located between the sole 23 and the rim 24 being in the extension of the sole 23.
  • Each tooth 22 has a gutter 25 (FIG. 5) formed in its facing side of the backsplash 20.
  • Each gutter is arranged according to the plan median tooth in which it is spared and extends into the sole 23 near the backsplash 20.
  • the gutters 25 serve to receive under the best conditions the stripped end (conductive core without sheath insulation) of an electric cable to be connected.
  • Each tooth 22 has, projecting from its opposite face to backsplash 20, a pin 26 serving, as will be seen below, stop stop for maintain the tooth 22 a spring 16 engaged thereon.
  • the rake 21 has a tab 27 ( Figure 6) located in the extension of the sole 23.

  • the subdivision body 17 is made of molded plastic electrically insulating.
  • the rack 40 has a sill 42 from which extend partition walls 43, here twelve in number, a cheek 44 being provided for each end of the rack 40.
  • the partitions 43 and the cheeks 44 are arranged parallel to each other. They are oriented each next a plane transverse to the direction along which the sill 42 extends.
  • each plays 44 and each partition 43 has, on the side that is seen at the top in this figure, a slot 45 located between two fingers 46 and 47, the finger 47 located on the side of the palisade 41 being longer than the finger 46 located on the side of the sill 42.
  • the slots 45 are arranged in the same plane, oriented transversely to the respective planes according to which are arranged the partitions 43 and the cheeks 44.
  • the sill 42 is formed by two elongate walls 48 and 49 arranged facing each other.
  • Each partition 43 is connected to the sill 42 by the face of the wall 49 that we see at the top in Figure 5.
  • the opposite face of the wall 49 looks at the wall 48.
  • the partitions 48 and 49 are each oriented according to a plane transverse to the respective planes along which are arranged the partitions 43 and the cheeks 44, the partition 49 being here oriented parallel to the slots 45.
  • the partitions 48 and 49 are connected to one another by one of their longitudinal ends, located on the side that we see on the right in Figure 5 and in bottom in Figure 7.
  • the angle between the planes along which are oriented respectively the partition 48 and the partition 49 is about 35 °.
  • Each partition 43 has a portion located in line with the wall 49 and an edge portion with respect to the wall 49, on the side opposite to that where the partitions 48 and 49 are connected to each other.
  • the fingers 46 and 47, and therefore the slot 45, are part of the portion overhang, which is less thick than the portion located in line with the wall 49.
  • the difference between two successive partitions 43 to the right of the wall 49 corresponds substantially to the width of a tooth 22 while beyond the shoulder 51 this difference (ie the difference between the portions in overflow of two successive walls 43) corresponds substantially to the width of the spring 16.
  • the wall 48 extends between the two cheeks 44, which each have a corresponding profile the combination of a wall 43 and a rib 50.
  • Each cheek 44 has, on the inner side (side that looks a partition 43), a shoulder 52 similar to the shoulder 51.
  • each cheek 44 and the neighboring wall 43 has a conformation similar to the space between two neighboring partitions 43 if is that the wall 49 is replaced by a detent notch 53 ( Figure 7).
  • Each cheek 44 carries, on the outer side, a detent 54 longitudinally oriented and serving, as will be seen below, the fixing of the connection strip 4 to a flange 2.
  • the pierced palisade 41 has a plurality of arms 60, here at number of fifteen, such an arm being provided for each cheek 44 and for each Partition 43.
  • Each arm 60 projects towards the same side as the overflow portion of partitions 43, from the end of such a partition or a cheek 44 opposite to the sill 42, the different arms 60 being oriented in the same way.
  • Each arm 60 has a substantially oriented distal portion parallel to the slots 45 and between the distal portion and the partition 43 or the cheek 44 from which this arm extends, an intermediate portion inclined towards this partition 43 or this cheek 44 and the opposite of the distal portion.
  • the palisade 41 has a rail 61 to which connects each of the arms 60.
  • Each lever 18 is made of molded insulating plastic on the plane electric.
  • bracket 65 with an angled profile and an elbow 66 of which a first branch 67, at one end of which is connected the shank 65, has, at this end, an impression 68 'of receiving the blade of a conventional electrician's screwdriver, and whose second branch 68, which connected to the other end of the branch 67, has a U-shaped section defining an internal space 69 in the form of a closed channel on the side of the branch 67.
  • this channel is generally parallel to the transverse end face of the lever 18 on the side of the lug 65 (face into which the imprint 68 'opens), which transverse end face is slightly curved.
  • Each spring 16 is deformed, from the state of rest that it takes spontaneously (state in which is the spring 16 illustrated in isolation on the 5), to bring the sections 30 and 34 closer, then is engaged on a tooth 22 respective with the junction between the sections 30 and 34 located forward while the face of the section 30 opposite the section 34 looks at the face of the tooth 22 and the sole 23 opposed to the backrest 20, the tooth 22 being engaged through the window 33 between the section 30 and the edge 35 until the tongue 31 is in rear of the pin 26, as seen more particularly in Figure 4.
  • the tooth 22 is then clamped by the spring 16 between the section 30 and the edge 35 so that the spring 16 is now maintained at the strip 15.
  • each of the levers 18 is placed with the lug 65 which comes facing the edge of the backsplash 20 and facing the side face thereof located on the side of the sole 23, with the branch 67 which comes next to the other lateral face of the backsplash 20 and the space 69 of the branch 68 which receives the spring 16 corresponding, the lever 18 can thus come into contact with the section 34 of this spring on the opposite side to the section 30.
  • the subdivision body 17 is then put in place by pass each of the portions in overflow of the partitions 43 between two springs 16 neighbors, the slot 45 of each of the partitions 43 and each of the cheeks 44 receiving a portion of the sole 23 located in the vicinity of a tooth 22, the withdrawal of the subdivision body 17 being prevented by the two notches 53 which engage each behind the flange 24 of a respective one of the teeth 22 extreme (see Figure 4).
  • Each lever 18 is thus held in place, while having the possibility to rotate, as seen in Figure 4, in the opposite direction of the needles of a shows to drive the section 34 of the spring 16 associated to the section 30.
  • Each arm 60 with the exception of the arms 60 extreme, actually bears on two levers 18 neighbors, the space between two arms 60 neighbors allowing to access a footprint 68 '.
  • the strip 15 protrudes slightly from each side beyond cheek 44, over a distance corresponding substantially to the length of the notch 54, the external lateral face of each extreme lever 18 being in the same plane as the outer lateral face of the corresponding cheek 44, the notch 54 being here aligned with the rake 21 of the ruler 15.
  • Each slot 7 of the flanges 2 of the splitter 1 has a profile corresponding to that of the strip 15 to which is added a notch 54.
  • a finger of retained (not visible in the drawings) is provided at the end of each slot 7 to the location corresponding to the notch 54.
  • a window 3 ( Figure 1) opens on the outside.
  • connection between the connection strips 4 and the flanges 2 of the splitter 1 is made by moving the flanges 2 towards each other while engaging each projecting end of the bars 4 (end section of a strip 15 and notch 54) in a respective slot 7 to the position shown in FIG. FIG. 1, where the notches 54 are each engaged on the retaining finger (no visible).
  • each portion of each bar 4 having a tooth 22, a spring 16 and a lever 18 forms a quick-connect terminal for a cable electrical, the different cables to be received in the terminals of the bar 4 being electrically connected (put to the same potential) by the strip 15.
  • the spring 16 urges the edge 35 towards the tooth 22, so that the end 80 is strongly pressed towards the tooth 22, and more generally towards the ruler 15, which makes a good electrical contact is established between the strip 15 and the bare end 80 of the cable 81, while the latter is firmly held at the bar 4.
  • the palisade 41 also maintains this position the bottom of the space 69 of the lever 18 against the spring 16 associated.
  • the subdivision body 17 provides for each tooth 22, and more generally for the quick-connect terminal to which belongs this tooth, a compartment delimited by the sill 42 and by two partitions 43 surrounding this tooth 22, except for the two teeth 22 extreme where the compartment is delimited by a cheek 44 and the wall 43 adjacent.
  • Each of these compartments leaves visible tooth 22 and a portion of section 32 of the spring 16 located in the vicinity of the edge 35 of the window 33, which allows the user to control at all times the position of the edge 35 with respect to tooth 22 and easily insert the stripped end of a cable between the edge 35 and tooth 22, the user can then control the correct disposition of each cables in the various terminals of the terminal strip 4.
  • the groove 25 further provides the tooth 22 with a conformation suitable for use in the best seat conditions at end 80.
  • the splitter 1 can thus be installed in an electrical panel of the same way as these previous dispatchers.
  • the levers 18 and / or the palisade 41 are shaped differently, for example the smooth 61 is removed, or even a flexible support member other than a palisade and not belonging to a body of subdivision is provided to keep the levers engaged on the backsplash 20 and resting on the respective springs 16.
  • levers 18 and the palisade 41 are removed, the operation of each terminal being done by a special tool having generally the shape of the assembly formed by the blade 82 and by one of levers 18; or so there is provided a slider similar to one of the levers 18 mounted movable along the backsplash 20, this cursor being moved to be put next to the terminal that we want to order.
  • connection strip does not has no subdivision body; and / or the slide is consistent differently, for example the backsplash such as 20 and / or the sole such as 23 are discontinuous.
  • the number of bars of the splitter's connection is different from four, for example two; and / or the number of terminals per connection strip is different from thirteen, for example six or eighteen.
  • the bar of connection is not part of a splitter but is an autonomous terminal block.
