Definitions

  • the present invention relates to an electrical wiring assistance device.
  • the present invention also relates to an electrical installation equipped with such a wiring assistance device.
  • US-A-3,090,936 describes an electrical connector in the form of a support strip comprising a plurality of connection wires.
  • FR-A-2 584 240 describes a device comprising a plurality of cable ends suitable for receiving wires to be connected. These tips are connected and held together. If these devices make it possible to keep a given wiring order, they do not solve the risk of errors in an installation having multiple identical devices.
  • the object of the invention is to propose a device for assisting in electrical wiring which facilitates operations on installations with complex wiring, in particular but not limited to when the installation comprises multiple identical or similar apparatuses mounted side by side.
  • the device for assisting in electrical wiring comprising a connection end piece intended to be fixed to the end of an electrical conductor and to be introduced into a connection terminal of an electrical apparatus. removably arranged on a base, a guide that can be positioned opposite the service position of the connection terminal of the electrical equipment.
  • the guide is fixed relative to the base, and comprises means for retaining the end piece in a retracted position allowing the dismantling of the electrical equipment from the base and for guiding the end piece from the position cleared at an engagement position of the nozzle in the connection terminal of the apparatus in the service position.
  • the endpiece In the absence of the apparatus, the endpiece is placed in the erased position in the guide, which in a way constitutes a memory of the position of the connection terminal to which the endpiece must be connected.
  • the equipment Once the equipment is in place, simply slide the end piece from the erased position to the position of engagement in the connection terminal. This guidance promotes the proper introduction of the tip into the terminal. If subsequently the equipment has to be dismantled to be inspected or replaced, we start by passing the tip from the engagement position to the erased position, we remove the equipment, we replace the new or inspected equipment, and the tip is redone in the engagement position in the connection terminal of the newly mounted apparatus.
  • the guide is part of a rack comprising several such aligned guides.
  • the rack can then be a separate piece, intended to be positioned by several end pieces because of their fixing in the connection terminals of several devices, so that when a end piece is in the retracted position, the rack remains in place thanks to the fixing of the other ends to the other apparatus.
  • the electrical installation comprising a base and a withdrawable and plug-in switchgear in a pinout direction, the switchgear comprising at least one connection terminal on a face parallel to the pinout direction, is characterized in that it further comprises a wiring assistance device according to the first aspect, opposite said at least one connection terminal, so that the guide and the end piece in the erased position allow the pinout and the drawout of the apparatus.
  • a programmable controller 1 which is only shown partially and very schematically receives on its signal inputs 2 signals which are a function of the state of detectors 3a-3f generally placed on the installation 10 that the PLC 1 must control.
  • the state of the detectors 3a-3f is transmitted to the signal inputs 2 of the automaton 1 via the interface device 11 which comprises, between installation signal terminals 24a and processing signal terminals 25a , relays which in the example are electromechanical relays 4a or an optocoupler 4b.
  • the interface device 11 comprises four common conductors 34a to 34d each connected to a respective supply terminal 35 of the interface device. Outside the interface device 11, an "installation” power source 7 and a “treatment” power source 9 are each mounted between two respective power terminals 35.
  • a processing circuit 5 and a detection circuit 6 each located partly in the interface device 11 and partly outside of it.
  • the detector 3a-3f is in series with the control member of the relay 4a or 4b and with the "installation" power source 7 or an external source 12.
  • the processing means 8 of the programmable controller 1 associated with the input 2 considered are in series with the controlled member of the relay 4a or 4b and with the "processing" power source 9.
  • Each input circuit 5 or detection 6, for its connection to the source 7 or 9, is in practice connected to the corresponding conductors 34a to 34d in the interface device 11.
  • the detection circuits 6 are not all connected in the same way to the source 7.
  • the detectors 3a, 3b, 3e and 3f are mounted between their "installation” signal terminal 24a and a respective “installation” common terminal 24b, connected directly in the interface device 11 to one of the conductors common 34d.
  • the detector 3c is mounted between a signal terminal 24a of the interface device 11 and the fixed potential terminal of the detector 3b.
  • the 3d detector cooperates with its own source 12 and is not at all connected to the source 7.
  • the "installation" common terminals 24b are all connected together by the same contact 41d to the common conductor 34d.
  • the processing means 8 are each mounted between a “processing” signal terminal 25a and a “processing” common terminal 25b.
  • the terminals 25b are all connected together by the same contact 41a to the common conductor 34a.
  • the interface device 11 comprises a base 28 having a face wall 29 through which are formed four rows of windows 31a, 31b, 31c and 31d.
  • the windows 31a to 31d are also arranged in columns perpendicular to the rows, each column having a window in each row.
  • a respective copper wire 34a to 34d is arranged which embodies the conductors 34a to 34d of FIG. 1.
  • the base 28 carries at one of its ends a power supply unit 36 which extends parallel to the window columns 31a-31d and includes the power supply terminals 35.
  • the interface device further comprises interface modules 39 which are mounted against the wall face 29 of the base and have, in the direction of this wall, contact clamps which plug into some of the windows 31a to 31d of the same column of the face wall 29, in a broaching direction perpendicular to this face , see the arrow to the right of FIG. 2, and pinch the common conductors 34a to 34d located opposite these windows.
  • Such a module with three contact clamps passing through the windows 31a, 31b and 31c can for example provide the interface between the detector 3f in FIG. 1 and the corresponding signal input 2 of the automaton, since such a module must be connected to conductors 34a, 34b and 34c.
  • the module will only have two clips to pass through the windows 31b and 31c.
  • the "installation" signal terminals 24a are constituted by wire clamps 20 provided on the modules 39 themselves.
  • the "installation" common terminals 24b are wire clamps 320 provided on a common module 72 interposed between the interface modules.
  • the signal and common "processing" terminals 25a and 25b are constituted by pins 220 of a connector 61 fixed to the base and intended to receive a complementary connector carried by the end of a cable coming from the automaton. .
  • Flexible wires 91 extending in a cavity 77 behind the connector 61 and in a chute 78 along the base connect each pin 220 with another wire clamp 20 of each interface module 39 or respectively with a wire clamp 320 of a common "treatment" module 73.
  • the wire clamps 20 on the "processing" side and the wire clamps 20 constituting the "installation” signal terminals 24a are in a symmetrical position on two opposite faces of the modules and therefore form two rectilinear rows, one above and the another below the modules.
  • the device comprises racks made of insulating material 79 each of which supports several adjacent connection ends 81, corresponding to several wire clamps 20 aligned side by side.
  • These racks 79 are separate parts of both modules and end pieces and they are only held in place by tightening the connection end pieces 81 in the respective wire clamps 20.
  • the racks 79 are obtained from a strip of molded plastic material which is cut to the desired length by means of sectioning primers 82 formed between neighboring cells 83 each provided for receiving a nozzle. .
  • the repeating step of the cells 83 corresponds to the repeating step of the window columns on the base.
  • Each cell 83 is constituted by a cylindrical conduit open laterally over most of its height, except in a base 84 of the rack, adjacent to a face of the rack intended to rest against the wall of the modules.
  • each cell is substantially semi-cylindrical at its end remote from the base and gradually closes in the direction of the base.
  • each cell has at its end opposite the base 84 a boss 86.
  • This rack 79 is provided for conventional connection end pieces 81 (FIG. 6) comprising for example a plastic body 87 extended by a label holder 88 and molded onto a metal tube 89 in which it is possible to engage, through the body 87 the stripped end (not shown) of a flexible wire 91.
  • connection end pieces 81 FIG. 6
  • the stripped end of the wire 91 is engaged in the projecting part of the metal tube 89, and that the latter is clamped between the jaws 92 of a clamp wire 20, the stripped end of the wire is pinched in the tube 89 when the latter is flattened by the clamping of the jaws 92.
  • the nozzle 81 For the installation of a nozzle 81 equipped with its flexible wire 91 in the rack 79, the nozzle 81 is presented in the inclined position as shown in FIG. 6 so that the body 87 engages laterally in the upper part semi-cylindrical of the cell 83.
  • the inclined position comes from the fact that the body 87 abuts laterally against the boss 86.
  • the tip 81 is moved axially towards the base 84, which forces the tip to align with the socket as shown in FIG. 7 and to snap behind the boss 86, because the body 87 reaches a less open region of the socket 83, as shown in FIG. 8.
  • the body 87 which can therefore no longer leave the cell 83, is guided axially by the cell 83, while the projecting part 89 of the tube has a large radial clearance in the orifice of the base 84.
  • the base of the label holder 88 abuts against the upper face of the base 84, while the projecting part 89 of the tube protrudes relative to the base 84.
  • the jaws 92 of the clamp can then be tightened wire 20 and this immobilizes not only the end piece 81 but also the rack 79 which is trapped between the base of the label holder 88 and the outer wall of the module to which the wire clamp 20 belongs.
  • the racks 79 allow, with a view to the removal of a module for its replacement and repair, after having loosened the corresponding wire clamp 20, to bring the end piece 81 in the erased position and to leave in this position in the absence of the module (tip 81 on the right in Figure 2) so that the location of the terminal to which the tip 81 must be connected is not lost in the absence of the module. This is important if you dismantle several modules at the same time: all the risks of incorrect wiring swapping on this occasion are eliminated. To completely release the end piece 81, it suffices to tilt the end piece (FIG. 6) to cross the hard point caused by the boss 86.
  • the racks 79 also make it possible to pre-schedule the wires and end pieces during assembly. initial interface device, while the modules are still missing.
  • each endpiece 81 is angularly wedged by its label holder 88 projecting into the lateral opening of the cell 83 of the rack.
  • the lateral opening allows the label fixed in service on the label holder to be read.
  • the invention is applicable to very diverse installations, for example to rows of contactors.
