Description

La présente invention concerne les dispositifs de connexion dans lesquels le raccordement d'un fil isolé à un contact autodénudant se fait par un poussoir portant le fil isolé et coulissant sur le contact. Elle porte plus particulièrement sur un poussoir de raccordement de ce type et sur une réglette de connexion équipée de tels poussoirs.The present invention relates to devices for connection in which the connection of an insulated wire to a insulation displacement contact is made by a push button carrying the wire insulated and sliding on the contact. She wears more particularly on a connection pusher of this type and on a connection strip equipped with such pushers.

Le document FR-A-2 666 953 décrit une réglette de connexion à contacts autodénudants montés dans un corps isolant et à poussoirs de raccordement montés coulissants sur les contacts. Le corps isolant présente des cheminées ouvertes sur l'une de ses faces dite avant, dans chacune desquelles s'étend l'un des contacts. Chaque poussoir coulisse ainsi dans l'une des cheminées, le long d'une fourche autodénudante du contact, entre une position enfoncée de raccordement du fil isolé au contact et une position rétractée d'insertion du fil isolé dans le poussoir ou de déconnexion du fil isolé précédemment raccordé au contact.The document FR-A-2 666 953 describes a strip of connection with insulation displacement contacts mounted in a body insulation and sliding push-buttons on the contacts. The insulating body has chimneys open on one of its front faces, in each of which extends one of the contacts. Each pusher thus slides in one of the chimneys, along a insulation displacement fork of the contact, between a position pressed in to connect the insulated wire to the contact and a retracted position for inserting the insulated wire into the pusher or disconnecting the insulated wire previously connected to the contact.

Le poussoir est simple et alors affecté au raccordement d'un fil isolé à un contact ou est double et alors affecté au raccordement simultané de deux fils isolés à deux contacts côte-à-côte de la réglette. Le poussoir simple ou double est réalisé en matière plastique.The button is simple and then assigned to connection of an insulated wire to a contact or is double and then assigned to the simultaneous connection of two insulated wires with two contacts side by side of the strip. The pusher single or double is made of plastic.

Le poussoir simple présente deux jambages longitudinaux en regard l'un de l'autre, qui sont solidaires d'une tête terminale d'actionnement et sont pourvus en vis-à-vis d'un trou d'insertion du fil isolé à travers chacun d'eux. Il présente également un Vé de guidage du fil isolé dans les trous des jambages, qui est solidaire de la tête et s'étend sur l'extérieur et en regard de l'un des jambages, en ayant son fond aligné avec les trous et son ouverture tournée vers la tête d'actionnement. Ce Vé coulisse sur l'extérieur de l'une des parois de la cheminée lorsque les jambages coulissent de part et d'autre du contact, le long de la fourche autodénudante de ce contact.The single pusher has two legs longitudinal facing each other, which are integral with a terminal actuating head and are provided opposite an insulated wire insertion hole through each of them. It also has a Vee for guiding the insulated wire in the holes of the legs, which is integral with the head and extends on the outside and opposite one of the legs, having its bottom aligned with the holes and its opening facing the actuating head. This Vee 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.

Pour améliorer la tenue mécanique du fil isolé raccordé au contact, il est prévu une fente calibrée de pincement du fil isolé dans la paroi de cheminée contre laquelle coulisse le Vé de guidage. Il est donc nécessaire de fournir au poussoir simple un effort cumulé, qui correspond à l'effort d'insertion du fil isolé dans et le long de la fourche autodénudante du contact et à l'effort d'insertion du fil isolé dans et le long de cette fente calibrée de pincement.To improve the mechanical strength of the insulated wire connected to the contact, a calibrated wire nipping slot is provided insulated in the chimney wall against which the Vé slides guidance. It is therefore necessary to provide the simple pusher with a cumulative effort, which corresponds to the insertion effort of the insulated wire in and along the insulation displacement fork of the contact and at the effort of inserting the insulated wire into and along this slit calibrated pinch.

Le poussoir double a deux paires de jambages côte à côte et deux Vé de guidage d'un même côté des jambages, qui sont tous solidaires de la tête terminale d'actionnement. L'effort cumulé à lui fournir est double du précédent. Il peut être limite pour l'actionnement au doigt du poussoir double, depuis sa position rétractée à sa position enfoncée.The double pusher has two pairs of legs side by side and two guide V on the same side of the legs, which are all integral with the terminal actuation head. The cumulative effort at providing it is double the previous one. It may be limited for finger actuation of the double pusher, from its position retracted to its depressed position.

Le document US-A-4 652 070 décrit une réglette de connexion, qui est du type de la réglette connue précédente et dont les poussoirs sont doubles et nécessitent un effort important et pouvant être limite pour leur actionnement au doigt.Document US-A-4 652 070 describes a strip of connection, which is of the type of the previous known strip and whose pushers are double and require effort important and may be limited for their finger actuation.

La présente invention a pour but de faciliter l'actionnement du poussoir, en particulier lorsque celui-ci est double, sans pour autant dégrader la qualité du raccordement de chaque fil à son contact et la tenue mécanique de ce fil au droit de son contact.The object of the present invention is to facilitate actuation of the pusher, in particular when it is double, without degrading the quality of the connection of each wire in contact and the mechanical resistance of this wire to the right of his contact.

Ce corps isolant présente deux rangées de cheminées 4, ouvertes sur une face avant, pour les contacts et les poussoirs. Les cheminées sont définies par des cloisons transversales notées 5A et 5B, qui sont alternativement discontinues et continues sur la largeur du corps isolant, et par une rangée longitudinale de cloisons médianes 6, communes à deux cheminées de chacune des rangées et constituant des cales de coupure dans la réglette.

Les poussoirs 3 sont identiques entre eux et décrits plus particulièrement en regard des figures 3 et 4, représentant l'un d'eux.The pushers 3 are identical to each other and described more particularly with regard to FIGS. 3 and 4, representing one of them.

Le poussoir 3 comporte deux paires de jamblages 11 et 12 référencés identiquement sur les deux paires et solidaires d'une tête terminale d'actionnement 10. Les deux jambages de chaque paire sont en regard l'un de l'autre. Ils ont chacun à l'identique un trou circulaire 13 ou 14, en vis-à-vis dans leur partie terminale opposée à la tête 10, d'insertion d'un fil isolé à travers chacun d'eux. Ils ont également une fente calibrée 15 ou 16, également en vis-à-vis, ouverte dans le trou du jambage et dirigée vers la tête, de pincement du fil isolé inséré dans les trous puis forcé dans les fentes de pincement 15 et 16. Les deux paires de jambages sont côte à côte et ont une fente de séparation 17 entre elles, pour coulisser de part et d'autre de l'une des cloisons transversales 5A du corps isolant (figure 2). Les deux jambages de chaque paire ont une fente de séparation 18 entre eux, pour coulisser de part et d'autre du contact.The pusher 3 has two pairs of jams 11 and 12 referenced identically on the two pairs and secured to a terminal actuating head 10. Both legs of each pair are facing each other. They each have an identical circular hole 13 or 14, in opposite in their terminal part opposite the head 10, inserting an insulated wire through each of them. they have also a 15 or 16 calibrated slot, also opposite, open in the hole of the jamb and directed towards the head, pinch of the insulated wire inserted in the holes then forced into the pinch slots 15 and 16. The two pairs jambs are side by side and have a separation slit 17 between them, to slide on either side of one transverse partitions 5A of the insulating body (Figure 2). The two legs of each pair have a slit of separation 18 between them, to slide on both sides of the contact.

Ce poussoir 3 comporte en outre une patte 20, relativement rigide s'étendant en regard des deux paires de jambages, sur leur longueur, et présentant deux Vés de guidage 21 pour les deux fils isolés à insérer dans les trous des deux paires de jambages. Le fond de chaque Vé de guidage est aligné avec les trous 13 et 14 des deux jambages correspondants, son ouverture étant du côté de la tête 10 et ses branches rigidifiant le poussoir. Chacun de ces deux Vés de guidage traverse de part en part la patte sur la partie 21A de ce Vé située au droit des trous 13 et 14 et des fentes de pincement 15 et 16 des deux jambages correspondants, mais n'est pas traversant sur la partie terminale de la patte située du côté de la tête, pour n'être qu'extérieur sur cette partie terminale de la patte.This pusher 3 further comprises a tab 20, relatively rigid extending opposite the two pairs of jambs, along their length, and presenting two Vs of guide 21 for the two insulated wires to be inserted in the holes in the two pairs of legs. The bottom of each Vé guide is aligned with the holes 13 and 14 of the two legs corresponding, its opening being on the side of the head 10 and its branches stiffening the pusher. Each of these two Vés guide crosses right through the tab on the part 21A of this Vé located to the right of holes 13 and 14 and pinch slots 15 and 16 of the two legs corresponding but is not crossing over the part end of the tab located on the side of the head, so as not to be than outside on this terminal part of the leg.

Cette patte 20 et les deux paires de jambages ont une fente de séparation 23 entre elles, pour que la patte coulisse sur l'extérieur de deux cheminées côte-à-côte du corps isolant, quand les paires de jambages coulissent dans ces deux cheminées. Cette patte 20 se prolonge à l'opposé de la tête par une bras élastique 24 saillant sur les jambages 11 et 12. Ce bras saillant est pourvu d'une fente d'élasticité 25, ouverte sur l'extrémité du bras, et de deux dents latérales 26 et 27, sur cette même extrémité. Il présente en outre une rainure axiale 28 sur sa face intérieure située du côté des jambages. Les dents latérales 26 et 27 limite la course du poussoir, quand ce poussoir est mis en position rétractée sur le corps isolant.This leg 20 and the two pairs of legs have a separation slot 23 between them, so that the tab slides on the outside of two side by side chimneys insulating body, when the pairs of legs slide in these two chimneys. This tab 20 extends opposite to the head by an elastic arm 24 projecting from the legs 11 and 12. This projecting arm is provided with a slot elasticity 25, open on the end of the arm, and two lateral teeth 26 and 27, on this same end. he further has an axial groove 28 on its face interior located on the side of the jambs. 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.

Sur ce poussoir, la tête 10 est légèrement saillante de part et d'autre des deux paires de jambages et ferme les cheminées du corps isolant. Les deux jambages extérieurs, non en regard de la patte 20, et tels que les jambages 11 présentent chacun une échancrure terminale définissant une encoche 31 sous la tête.On this pusher, the head 10 is slightly protruding on both sides of the two pairs of jambs and close them insulating body chimneys. The two outer legs, not opposite the tab 20, and such as the legs 11 each have a terminal notch defining a notch 31 under the head.

Chaque encoche constitue un moyen de prise sur le poussoir, en particulier pour son actionnement de sa position enfoncée vers sa position rétractée.Each notch constitutes a means of taking on the pusher, in particular for its actuation of its position pressed towards its retracted position.

Il est en outre prévu deux trous de test 32 et 33, réalisés à travers la tête et débouchant chacun sur le fond de l'une des fentes telles que 18 entre les deux jambages de la même paire, à proximité de l'extrémité intérieure échancrée du fond de chacune de ces fentes. In addition, two test holes 32 and 33 are provided, made through the head and each opening on the bottom from one of the slots such as 18 between the two legs of the same pair, near the inner end indented from the bottom of each of these slots.

Les dispositions particulières prévues, en correspondance de celles du poussoir, sur le corps isolant de la réglette sont précisées plus particulièrement en regard des figures 1 ou 2 et 5.The specific provisions provided, in correspondence of those of the pusher, on the insulating body of the strip are specified more particularly in see Figures 1 or 2 and 5.

Le corps isolant 1 présente une série de lumières oblongues 35 le long de chaque rangée de contacts. Chaque lumière est en regard de la fourche autodénudante de l'un des contacts et est réalisée sur l'une des parois de la cheminée, qui est parallèle au contact. Dans cette réalisation, à deux rangées de contacts et à câles de coupure 6 définissant entre les rangées des parois communes pour les cheminées en vis-à-vis, ces lumières sont réalisées sur les grandes parois longitudinales du corps isolant. Les extrémités 35A de ces lumières, situées à proximité de la face avant, sont fermées. Elles sont alignées avec l'entrée de la fourche autodénudante des contacts et sont prévues pour être alignées avec les trous 13 et 14 des jambages des poussoirs, quand ces poussoirs sont en position rétractée.The insulating body 1 has a series of lights oblong 35 along each row of contacts. Each light is next to the insulation displacement fork of one contacts and is made on one of the walls of the chimney, which is parallel to the contact. In this realization, with two rows of contacts and with cables cut 6 defining between the rows of the common walls for the facing chimneys, these lights are made on the large longitudinal walls of the insulating body. The 35A ends of these lights, located near the front side, are closed. They are aligned with the entrance of the insulation displacement fork of the contacts and are provided to be aligned with the holes 13 and 14 of the legs of the pushers, when these pushers are in the retracted position.

Le corps isolant 1 présente, sur ses grandes parois longitudinales, une série de pontets de butée 36 affectés aux différents poussoirs. Ces pontets 36 sont légèrement saillants extérieurement. Chacun d'eux reçoit le bras 24 de l'un des poussoirs et permet le coulissement de ce bras contre la paroi du corps, lors de la mise en position enfoncée du poussoir, et la retenue en butée des dents terminales 26 et 27 de ce bras quand le poussoir arrive en position rétractée rendue limite.The insulating body 1 has, on its large walls longitudinal, a series of stop bridges 36 affected to the different pushers. These bridges 36 are slightly externally salient. 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 positioning pressed in the pusher, and the retainer in abutment of the teeth terminals 26 and 27 of this arm when the pusher arrives in retracted position made limit.

Sur ce corps isolant, il est en outre prévu une série de rainures extérieures 38 réalisées sur ses grandes parois et ouvertes sur la face avant. Chacune de ces rainures est centrée entre les deux cheminées recevant l'un des poussoirs et correspond à la rainure 28 de ce poussoir. Les rainures 38 et 28 viennent en vis-à-vis et évitent que les parois soient juxtaposées et ainsi allongent les lignes de fuites. Elle permettent l'évaporation des éventuelles traces d'humidité canalisées sur l'extérieur des cheminées. On this insulating body, a series is further provided. of external grooves 38 made on its large walls and open on the front side. Each of these grooves is centered between the two chimneys receiving one of the pushers and corresponds to the groove 28 of this pusher. The grooves 38 and 28 face each other and prevent the walls are juxtaposed and thus lengthen the lines of leakage. They allow the evaporation of any traces humidity channeled on the outside of the chimneys.

Les figures 5 et 6 permettent de préciser les fonctions assurées par les poussoirs et la réglette ainsi équipée.Figures 5 and 6 make it possible to specify the functions provided by the pushbuttons and the strip as well equipped.

Pour le raccordement de deux fils isolés 7 à deux contacts côte-à-côte, le poussoir 3 concerné est mis en position limite rétractée, pour laquelle les deux dents latérales 26 et 27 sont en butée sur le pontet 36 extérieur aux deux cheminées correspondantes, ainsi qu'illustré à gauche dans ces figures 5 et 6. Les fils 7 sont insérés tour à tour dans les trous des jambages, en se servant du Vé de guidage 21 correspondant pour amener plus facilement chaque fil dans ces trous. Chaque fil est simultanément reçu dans l'extrémité 35A de la lumière 35. Le raccordement des deux fils aux deux contacts 2 est réalisé en appuyant sur le poussoir. Chacun des fils pénètre alors tout d'abord dans les fentes de pincement 15 et 16 prévues sur les jambages puis dans la fourche autodénudante du contact.For the connection of two insulated wires 7 to two side-by-side contacts, push-button 3 concerned is put in retracted limit position, for which both teeth lateral 26 and 27 are in abutment on the external trigger guard 36 to the two corresponding chimneys, as illustrated in left in these figures 5 and 6. The wires 7 are inserted round alternately in the holes of the jambs, using the Vé de corresponding guide 21 to more easily bring each wire in these holes. Each wire is simultaneously received in the end 35A of the light 35. The connection of the two wire at both contacts 2 is achieved by pressing the pusher. Each of the wires then first enters the pinch slots 15 and 16 provided on the legs then in the insulation displacement fork of the contact.

Pour déconnecter les deux fils précédemment raccordés aux deux contacts, on utilise avantageusement un tournevis ou analogue, que l'on vient placer dans les encoches 31 du poussoir en position enfoncée, pour faire levier sur la câle de coupure 6, ceci tout au moins pendant le début de la course du poussoir vers sa position rétractée. Ce mode d'actionnement permet de ne laisser que de faibles intervalles entre les têtes des poussoirs enfoncés ou entre les têtes et les câles sur la face avant de la réglette. Au cours de l'actionnement en position rétractée, les deux fils isolés sortent des deux fourches autodénudantes 2A des deux contacts concernés puis des fentes de pincement 15, 16 des jambages, dès lors que la force de serrage dans les fentes de pincement est supérieure à celle de serrage dans les fourches autodénudantes. L'extrémité fermée 35A des deux lumières 35 dans lesquelles coulissent ces fils au cours de leur déconnexion assure la sortie complète des deux fils de leur fente de pincement. Les fils peuvent alors être extraits sans résistance des trous 13 et 14 dans lesquels ils sont ramenés.To disconnect the two previously connected wires at both contacts, a screwdriver is advantageously used or the like, which is placed in the notches 31 of the push-button in the depressed position, to pry on the cable 6, at least during the start of the stroke of the pusher towards its retracted position. This mode actuation allows to leave only weak intervals between the heads of the depressed pushers or between the heads and shims on the front of the strip. At during actuation in the retracted position, the two wires isolated come out of the two insulation displacement forks 2A from both contacts concerned then pinch slots 15, 16 of legs, as soon as the clamping force in the slots pinch is greater than that of clamping in insulation displacement forks. The closed end 35A of the two lights 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.

La figure 6 montre en outre que les contacts traversent une base 1C de la partie avant 1A du corps isolant, en étant retenus dans cette base et que deux contacts en vis-à-vis sur les deux rangées sont élastiquement en pression l'un contre l'autre dans la partie arrière 1B du corps isolant.Figure 6 further shows that the contacts cross a base 1C of the front part 1A of the body insulating, being retained in this base and that two opposite contacts on the two rows are elastically in pressure against each other in the part rear 1B of the insulating body.

Cette partie arrière est compartimentée transversalement par des cloisons 5C, ayant entre elles un pas double de celui des cloisons de la partie avant 1A du corps isolant 1 et correspondant aux seules cloisons 5B (figure 2), et longitudinalement par les cales de coupure 6. Ces câles traversent la base 1C et sont coulissantes dans cette base. Chacune assure ou non la coupure de deux paires de contacts en vis-à-vis sur les deux rangées.This rear part is compartmentalized transversely by partitions 5C, having between them a not double that of the partitions of the front part 1A of the insulating body 1 and corresponding to only partitions 5B (Figure 2), and longitudinally by the shims 6. These cables pass through the base 1C and are sliding in this base. Each ensures or does not cut two pairs of opposite contacts on the two rows.

L'une de ces câles est représentée dans la figure 7.One of these legs is shown in Figure 7.

Elle est réalisée en une matière isolante. Elle se présente sous la forme d'une plaquette parallélépipédique 40, ayant une paire de bras de coupure 41 et une paire de bras de butée 42 solidaires les uns des autres et par une patte de liaison 43 de la plaquette 40. Les bras 41 sont dans le plan de la plaquette et les bras 42 lui sont transversaux. Ils définissent ensemble l'extrémité dite arrière de la câle, venant dans la partie arrière du corps isolant. L'une des paires de bras, ici les bras 41, assure le guidage de la câle dans la partie arrière, soit entre deux cloisons 5C. Cette paire de bras est à cet effet de longueur sensiblement égale à la dimension correspondante de chaque compartiment de la partie arrière.It is made of an insulating material. She is present in the form of a parallelepiped plate 40, having a pair of cutting arms 41 and a pair of abutment arms 42 integral with each other and by a connecting lug 43 of the wafer 40. The arms 41 are in the plane of the plate and the arms 42 are transverse. They define together the so-called end back of the tail, coming in the back part of the body insulating. One of the pairs of arms, here the arms 41, ensures the guide of the cable in the rear part, between two partitions 5C. This pair of arms is for this purpose length substantially equal to the corresponding dimension of each compartment of the rear part.

Les bras de coupure 41 ont leur face située en regard de la plaquette présentant une forme arrondie, pour qu'ils s'insèrent plus facilement entre les contacts en pression élastique. Les bras 42 sont de section droite rectangulaire et destinés à limiter la course de la câle lors de sa mise en position de coupure, par butée de ces bras contre la base de la partie avant.The cutting arms 41 have their face located opposite of the plate having a rounded shape, so that they fit more easily between pressure contacts elastic. 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.

Cette câle de coupure 6 présente sur son extrémité dite avant deux encoches 44 quasi-terminales dans les grandes faces de la plaquette, pour son actionnement en position de coupure.This cutting wire 6 has on its end said before two quasi-terminal 44 notches in the large faces of the wafer, for its actuation in cut-off position.

En se référant à nouveau à la figure 6, on comprend aisément que la cale en position enfoncée à fond dans le corps isolant est en position de non coupure. Son actionnement en position de coupure peut être assuré aisément à l'aide d'un tournevis ou analogue inséré dans l'une des encoches et faisant levier sur l'un des deux poussoirs en position enfoncée de part et d'autre d'elle.Referring again to Figure 6, we understand easily that the wedge in the fully inserted position in the insulating body is in the non-cut position. His actuation in cut-off position can be ensured easily using a screwdriver or the like inserted into one of the notches and leveraging one of the two pushers in the depressed position on either side of it.

Chaque cale de coupure sert en outre de butée de fin d'insertion des deux fils dans l'un ou l'autre des poussoirs de part et d'autre d'elle.Each cutting block also serves as an end stop insertion of the two wires in one or other of the pushers on both sides of it.

En variante par rapport au mode de réalisation illustré, il est évident que les poussoirs de raccordement et de pincement de chaque fil isolé au droit du contact auquel est raccordé ce fil peuvent être des poussoirs simples.As an alternative to the embodiment illustrated, it is obvious that the connection pushers and pinching of each insulated wire at the right of contact to which this wire is connected can be pushers simple.

En variante également, la réglette équipée de poussoirs peut comporter plusieurs doubles rangées de contacts, chaque double rangée étant identique à celle de la réglette illustrée avec une rangée médiane de cales de coupure associées, ou peut comporter un nombre quelconque de rangées de contacts, avec chaque contact accessible en face avant et en face arrière et non en pression avec le contact en vis-à-vis et sans cales de coupure entre eux.Also in a variant, the strip equipped with pushers can have several double rows of contacts, each double row being identical to that of the strip shown with a middle row of shims associated cut, or may include any number of rows of contacts, with each contact accessible opposite front and rear and not under pressure with the contact opposite and without cutting blocks between them.

En variante également, les poussoirs simples ou doubles peuvent être équipés de dents de retenue en position rétractée, non plus sur l'extérieur des cheminées concernées mais sur l'intérieur de ces cheminées. Ainsi ces dents de retenue peuvent être latérales sur la seule paire de jambages ou sur les deux paires ou sur un bras prolongeant l'un des jambages de la seule paire ou de chacune des deux paires, pour venir en butée sur des épaulements alors prévus en correspondance à l'intérieur du corps isolant.Alternatively also, the simple pushers or double can be fitted with position retaining teeth retracted, no longer on the outside of the chimneys concerned but on the inside of these chimneys. So these teeth of retainers can be lateral on the single pair of legs or on both pairs or on an extending arm one of the legs of the single pair or both pairs, to come into abutment on shoulders then provided in correspondence inside the insulating body.
