Definitions

  • the present invention relates to connection devices in which the connection of an insulated wire to a insulation displacement contact is made by a pusher carrying the insulated wire and sliding on the contact. It relates more particularly to a connection pusher of this type and to a connection strip equipped with such pusher.
  • connection strip with insulation displacement contacts mounted in an insulating body and with connection pushers mounted sliding on the contacts.
  • the insulating body has open chimneys on one of its so-called front faces, in each of which extends one of the contacts.
  • Each pusher thus slides in one of the chimneys, along an insulation displacement fork of the contact, between a depressed position for connecting the insulated wire to the contact and a retracted position for inserting the insulated wire into the pusher or for disconnecting the wire. isolated previously connected to the contact.
  • the push-button is simple and then assigned to the connection of an insulated wire to a contact or is double and then assigned to the simultaneous connection of two insulated wires to two contacts side by side of the strip.
  • the single or double pusher is made of plastic.
  • the simple pusher has two longitudinal legs facing each other, which are integral with a terminal actuating head and are provided opposite an insertion hole for the insulated wire through each of them. It also has an insulated wire guide V in the holes of the legs, which is integral with the head and extends on the outside and facing one of the legs, having its bottom aligned with the holes and its opening facing the actuating head. This V slides on the outside of one of the walls of the chimney when the legs slide on either side of the contact, along the insulation displacement fork of this contact.
  • a calibrated pinch slot for the insulated wire is provided in the chimney wall against which the guide V slides. It is therefore necessary to provide the simple pusher with a cumulative force, which corresponds to the force for inserting the insulated wire into and along the insulation displacement fork of the contact and to the force for inserting the insulated wire into and along of this calibrated pinch slot.
  • the double pusher has two pairs of legs side by side and two Vee guides on the same side of the legs, which are all integral with the terminal actuating head.
  • the cumulative effort to provide it is double the previous one. It can be limited for the finger actuation of the double pusher, from its retracted position to its depressed position.
  • the present invention aims to facilitate the actuation of the pusher, in particular when the latter is double, without degrading the quality of the connection of each wire in contact with it and the mechanical strength of this wire in line with its contact.
  • a push button for connecting an insulated wire to an insulation displacement contact by sliding of said push button on said contact, comprising a terminal actuating head and at least one pair of longitudinal legs facing each other. , integral with said head and provided opposite a hole for inserting the insulated wire, characterized in that the two legs of each pair are further provided facing a calibrated slot of pinch of the insulated wire, open in the hole of the jamb and directed towards said head.
  • connection strip equipped with such pushers, comprising an insulating body, chimneys defined in the insulating body and open on a so-called front face of said body, insulation displacement contacts. mounted in the insulating body, each extending in one of the chimneys and provided with a insulation displacement fork, itself open opposite said front face, and said pushers mounted in the insulating body by sliding in the chimneys and on said contacts, between a recessed connection position and a position partially outside the chimneys and said retracted, and in which said chimneys each have a first wall parallel to the internal contact and provided with an elongated passage located opposite the insulation displacement fork of this contact and assigned to the insulated wire connected to this contact, characterized in that said passage is a light closed at its two ends and having a width at least equal to the diameter of the insulated wire, one of the ends of said light being substantially terminal on the chimney and close to said front face of the insulating body and serving as a stop for the forced sliding of the insulated wire, from the pinch slots at the
  • connection strip has an insulating body 1, in which are mounted two rows of insulation displacement contacts 2, parallel to its large longitudinal faces, and slide pushers 3.
  • This insulating body has two rows of chimneys 4, open on a front face, for contacts and pushers.
  • the chimneys are defined by transverse partitions denoted 5A and 5B, which are alternately discontinuous and continuous over the width of the insulating body, and by a longitudinal row of median partitions 6, common to two chimneys of each of the rows and constituting shims in the strip.
  • the insulated wires to be connected to the contacts are designated below under the reference 7.
  • the body is in two parts, one front 1A and the other rear 1B, which are assembled to one another and in which the contacts extend.
  • This strip is connected to insulated wires to the contacts, made entirely on the front face, by the pushers 3.
  • These pushers are here double for the simultaneous connection of two insulated wires in the insulation displacement fork 2A, accessible on the front face, of two contacts side by side in the same row.
  • the pushers 3 are identical to each other and described more particularly with reference to Figures 3 and 4, showing one of them.
  • the pusher 3 comprises two pairs of jams 11 and 12 referenced identically on the two pairs and secured to a terminal actuating head 10.
  • the two legs of each pair are opposite one another. They each have an identical circular hole 13 or 14, facing each other in their end portion opposite to the head 10, for inserting an insulated wire through each of them. They also have a calibrated slot 15 or 16, also opposite, open in the hole of the jamb and directed towards the head, pinching the insulated wire inserted in the holes then forced into the pinching slots 15 and 16.
  • the two pairs of legs are side by side and have a separation slot 17 between them, for sliding on either side of one of the transverse partitions 5A of the insulating body ( Figure 2).
  • the two legs of each pair have a separation slot 18 between them, to slide on either side of the contact.
  • This pusher 3 further comprises a relatively rigid tab 20 extending opposite the two pairs of legs, along their length, and having two guide Vs 21 for the two insulated wires to be inserted into the holes of the two pairs of legs.
  • the bottom of each Vé guide is aligned with the holes 13 and 14 of the two corresponding legs, its opening being on the side of the head 10 and its branches stiffening the pusher.
  • Each of these two guide Vs goes right through the tab on the part 21A of this V located at the right of the holes 13 and 14 and the pinch slots 15 and 16 of the two corresponding legs, but is not crossing on the end part of the leg located on the side of the head, so as to be only outside on this end part of the leg.
  • This tab 20 and the two pairs of legs have a separation slot 23 therebetween, so that the tab slides on the outside of two chimneys side by side of the insulating body, when the pairs of legs slide in these two chimneys.
  • This tab 20 is extended opposite the head by an elastic arm 24 projecting from the legs 11 and 12.
  • This projecting arm is provided with an elasticity slot 25, open on the end of the arm, and two lateral teeth 26 and 27, on this same end. It also has an axial groove 28 on its inner face located on the side of the legs. The lateral teeth 26 and 27 limit the stroke of the pusher, when this pusher is placed in the retracted position on the insulating body.
  • the head 10 is slightly protruding on either side of the two pairs of legs and closes the chimneys of the insulating body.
  • the two outer legs, not facing the tab 20, and such that the legs 11 each have a terminal notch defining a notch 31 under the head.
  • Each notch constitutes a gripping means on the pusher, in particular for its actuation from its depressed position towards its retracted position.
  • test holes 32 and 33 are provided, made through the head and each opening on the bottom of one of the slots such as 18 between the two legs of the same pair, near the internal scalloped end. from the bottom of each of these slots.
  • the insulating body 1 has a series of oblong slots 35 along each row of contacts. Each light is opposite the insulation displacement fork of one of the contacts and is produced on one of the walls of the chimney, which is parallel to the contact. In this embodiment, with two rows of contacts and with cutting shells 6 defining between the rows of the common walls for the chimneys facing each other, these openings are produced on the large longitudinal walls of the insulating body.
  • the ends 35A of these lights, located near the front face, are closed. They are aligned with the entry of the insulation displacement fork of the contacts and are intended to be aligned with the holes 13 and 14 of the legs of the pushers, when these pushers are in the retracted position.
  • the insulating body 1 has, on its large longitudinal walls, a series of stop bridges 36 assigned to the different pushers. These bridges 36 are slightly projecting externally. Each of them receives the arm 24 of one of the pushers and allows the sliding of this arm against the wall of the body, when the pushbutton is placed in the depressed position, and the retention in abutment of the end teeth 26 and 27 of this arm when the pusher reaches the retracted position made limit.
  • each of these grooves is centered between the two chimneys receiving one of the pushers and corresponds to the groove 28 of this pushbutton.
  • the grooves 38 and 28 face each other and prevent the walls from being juxtaposed and thus lengthen the lines of leakage. They allow the evaporation of any traces of humidity channeled on the outside of the chimneys.
  • FIGS 5 and 6 make it possible to specify the functions performed by the pushers and the strip thus equipped.
  • the pusher 3 concerned For the connection of two insulated wires 7 with two side-by-side contacts, the pusher 3 concerned is placed in the retracted limit position, for which the two lateral teeth 26 and 27 are in abutment on the trigger guard 36 outside the two corresponding chimneys, as illustrated on the left in these figures 5 and 6.
  • the wires 7 are inserted in turn in the holes of the legs, using the corresponding guide V 21 to more easily bring each wire into these holes.
  • Each wire is simultaneously received in the end 35A of the light 35.
  • the connection of the two wires to the two contacts 2 is carried out by pressing the push-button.
  • Each of the wires then firstly enters the pinching slots 15 and 16 provided on the legs then in the insulation displacement fork of the contact.
  • a screwdriver or the like is advantageously used, which is placed in the notches 31 of the pusher in the depressed position, to pry on the cut-off wire 6, this at least for the start of the stroke of the pusher towards its retracted position.
  • This mode of actuation makes it possible to leave only small intervals between the heads of the pushed pushers or between the heads and the shims on the front face of the strip.
  • the two insulated wires exit from the two insulation displacement forks 2A of the two contacts concerned, then from the gripping slots 15, 16 of the legs, as soon as the clamping force in the gripping slots is greater than that of tightening in the insulation displacement forks.
  • the closed end 35A of the two slots 35 in which these wires slide during their disconnection ensures the complete exit of the two wires from their pinch slot.
  • the wires can then be extracts without resistance from holes 13 and 14 in which they are brought back.
  • FIG. 6 also shows that the contacts pass through a base 1C of the front part 1A of the insulating body, while being retained in this base and that two opposite contacts on the two rows are elastically in pressure, one against the other. the other in the rear part 1B of the insulating body.
  • This rear part is divided transversely by partitions 5C, having between them a pitch double that of the partitions of the front part 1A of the insulating body 1 and corresponding to the only partitions 5B (FIG. 2), and longitudinally by the shims 6.
  • partitions 5C This rear part is divided transversely by partitions 5C, having between them a pitch double that of the partitions of the front part 1A of the insulating body 1 and corresponding to the only partitions 5B (FIG. 2), and longitudinally by the shims 6.
  • These shells cross the base 1C and are sliding in this base. Each ensures or does not cut two pairs of contacts facing each other on the two rows.
  • It is made of an insulating material. It is in the form of a parallelepiped plate 40, having a pair of cutting arms 41 and a pair of stop arms 42 integral with each other and by a connecting tab 43 of the plate 40.
  • the arms 41 are in the plane of the wafer and the arms 42 are transverse to it. They together define the so-called rear end of the cable, coming in the rear part of the insulating body.
  • One of the pairs of arms, here the arms 41 guides the cable in the rear part, that is to say between two partitions 5C. This pair of arms is for this purpose of length substantially equal to the corresponding dimension of each compartment of the rear part.
  • the cutting arms 41 have their face located opposite the plate having a rounded shape, so that they are more easily inserted between the contacts under elastic pressure.
  • the arms 42 are of rectangular cross section and intended to limit the travel of the cable during its setting in the cut-off position, by abutment of these arms against the base of the front part.
  • This cutoff wire 6 has on its so-called front end two quasi-terminal notches 44 in the large faces of the wafer, for its actuation in the cutoff position.
  • the wedge in the fully pressed position in the insulating body is in the non-cut position. Its actuation in the cut-off position can easily be ensured using a screwdriver or the like inserted in one of the notches and levering on one of the two pushers in the depressed position on either side of it.
  • Each cutting block also serves as an end stop for inserting the two wires into one or other of the pushers on either side of it.
  • connection and pinching pushers of each insulated wire at the level of the contact to which this wire is connected can be simple pushers.
  • the strip fitted with pushers may have several double rows of contacts, each double row being identical to that of the strip illustrated with a middle row of associated cutting shims, or may include any number of rows of contacts, with each contact accessible from the front and rear face and not under pressure with the contact opposite and without shims between them.
  • the single or double pushers can be fitted with retaining teeth in the retracted position, no longer on the outside of the chimneys concerned but on the inside of these chimneys.
  • these retaining teeth can be lateral on the single pair of legs or on the two pairs or on an arm extending one of the legs of the single pair or of each of the two. pairs, to come into abutment on shoulders then provided in correspondence inside the insulating body.
