L'invention concerne, de façon générale, le domaine de la connectique, et en particulier des accessoires de connexion destinés aux applications informatiques.The invention relates generally to the field of connectors, and in particular connection accessories for computer applications.

Plus précisément, l'invention concerne une prise destinée à équiper un câble multiconducteur et comprenant au moins un peigne amovible, un bornier de connexion et des moyens de serrage, le peigne étant traversé par un canal central destiné à offrir un passage au câble suivant un axe longitudinal et présentant, sur une première face frontale, des entailles disposées autour du canal central et dont chacune est dimensionnée pour maintenir un conducteur isolé correspondant du câble, le bornier étant adapté à recevoir une fiche amovible multiconductrice et comprenant, sur une deuxième face frontale adjacente à la première face frontale en configuration montée de la prise, des contacts électriques autodénudants dont chacun est adapté à recevoir et dénuder, en phase de montage de la prise, un conducteur isolé correspondant du câble par un mouvement relatif de ce contact et de ce conducteur isolé maintenu dans une entaille du peigne, et les moyens de serrage comprenant un dispositif d'assemblage à vis et à écrou traversé par le canal central et opérant ledit mouvement relatif en phase de montage, la vis étant montée solidaire du peigne en translation axiale et à libre rotation par rapport à lui autour de l'axe. Une prise de ce type est notamment connue de l'homme du métier par le brevet US 5 752 849 et le brevet EP 0 980 117 qui est considéré comme étant l'état de la technique le plus pertinent. En dépit de son intérêt, la prise décrite dans ce brevet antérieur est d'une utilisation relativement peu aisée, la présente invention ayant précisément pour but de proposer une prise d'emploi beaucoup plus simple et rapide.More specifically, the invention relates to a socket intended to equip a multicore cable and comprising at least one removable comb, a terminal block and clamping means, the comb being traversed by a central channel intended to provide a passage to the cable following a longitudinal axis and having, on a first front face, notches arranged around the central channel and each of which is dimensioned to maintain a corresponding insulated conductor of the cable, the terminal block being adapted to receive a removable multicore plug and comprising, on a second end face adjacent to the first face in the mounted configuration of the plug, insulation displacement electrical contacts each of which is adapted to receive and strip, in the mounting phase of the socket, a corresponding insulated conductor of the cable by a relative movement of this contact and this insulated conductor held in a notch of the comb, and the clamping means com taking a screw and nut assembly device traversed by the central channel and operating said relative movement in the mounting phase, the screw being integral with the comb in axial translation and free rotation relative thereto about the axis. A plug of this type is known in particular to a person skilled in the art by the patent. US 5,752,849 and the patent EP 0 980 117 which is considered to be the most relevant state of the art. In spite of its interest, the grip described in this prior patent is relatively easy to use, the present invention being specifically intended to offer a job much simpler and faster.

A cette fin, la prise de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisée en ce que le bornier comprend au moins deux colonnes faisant saillie axialement de la deuxième face frontale, en ce que l'écrou est au moins partiellement constitué d'encoches hélicoïdales pratiquées dans les colonnes, et en ce que cette prise comprend une butée de rotation bloquant la rotation du peigne autour de l'axe et par exemple au moins partiellement constituée par l'une des colonnes.To this end, the taking of the invention, moreover in accordance with the generic definition given in the preamble above, is essentially characterized in that the terminal block comprises at least two columns projecting axially from the second end face, in that the nut is at least partially constituted by helical notches made in the columns, and in that this catch comprises a stop of rotation blocking the rotation of the comb around the axis and for example at least partially constituted by the one of the columns.

De préférence, les entailles débouchent sur des faces latérales du peigne, libres et adjacentes à la première face frontale.Preferably, the notches open on side faces of the comb, free and adjacent to the first end face.

La vis comprend avantageusement au moins deux rampes hélicoïdales présentant un développement angulaire au plus égal à un tour, et s'engageant respectivement dans les encoches hélicoïdales, en phase de montage de la prise, par un mouvement de vissage de la vis.The screw advantageously comprises at least two helical ramps having an angular development at most equal to one turn, and engaging respectively in the helical notches, in the mounting phase of the socket, by a screwing movement of the screw.

Cette vis peut aussi comporter des reliefs de préhension disposés de part et d'autre de l'axe et faisant saillie axialement à l'opposé de la première face frontale.This screw may also include gripping reliefs disposed on either side of the axis and projecting axially opposite the first end face.

Les colonnes présentent de préférence des faces d'extrémité hélicoïdales respectives, parallèles aux encoches respectivement pratiquées dans ces colonnes, participant à la constitution de l'écrou, et servant d'appui à des faces internes respectives des rampes hélicoïdales de la vis dans une phase de démontage de la prise.The columns preferably have respective helical end faces, parallel to the notches respectively formed in these columns, participating in the constitution of the nut, and serving as support for respective inner faces of the ramps helical screws in a disassembly phase of the plug.

Il est par ailleurs judicieux de prévoir que cette prise comprenne un détrompeur disposé sur l'une au moins des première et deuxième faces frontales et n'autorisant l'assemblage du peigne et du bornier que dans une seule position angulaire relative autour de l'axe.It is also wise to provide that this socket comprises a polarizer disposed on at least one of the first and second end faces and allowing assembly of the comb and the terminal block only in a single relative angular position around the axis .

Le logement servant de réceptacle pour la fiche amovible peut être constitué par un logement axial du bornier, disposé à l'opposé de la deuxième face frontale.The housing serving as a receptacle for the removable plug may be constituted by an axial housing of the terminal block, disposed opposite the second end face.

Dans un mode de réalisation industriellement optimisé, le peigne peut comporter une cheminée cylindrique sur laquelle la vis est enfilée à force axialement, et présentant un rebord radialement élastique maintenant la vis prisonnière le long de l'axe longitudinal, l'un au moins des éléments constitués par le peigne, le bornier et la vis pouvant par ailleurs être réalisé au moins partiellement par moulage d'un matériau thermoplastique.In an industrially optimized embodiment, the comb may comprise a cylindrical chimney on which the screw is threaded axially, and having a radially elastic rim holding the screw captive along the longitudinal axis, at least one of the elements formed by the comb, the terminal block and the screw may also be made at least partially by molding a thermoplastic material.

La vis peut aussi présenter une collerette dotée d'un ou plusieurs reliefs radiaux, chaque relief radial étant propre à coopérer avec l'arête d'une colonne correspondante pour permettre un encliquetage réversible de la vis par rapport à cette colonne à la fin de la phase de montage.The screw may also have a flange provided with one or more radial reliefs, each radial relief being adapted to cooperate with the edge of a corresponding column to allow reversible latching of the screw relative to this column at the end of the assembly phase.

L'invention est particulièrement adaptée à la réalisation d'une prise conforme à la norme ISO CEI 11 801.The invention is particularly suitable for making a socket compliant with the ISO IEC 11801 standard.

Comme annoncé précédemment, l'invention concerne une prise destinée à équiper un câble multiconducteur K et répondant par exemple à la norme ISO CEI 11 801, cette prise comprenant au moins un peigne amovible 1, un bornier de connexion 2 et des moyens de serrage tels que 3 et 4.As previously announced, the invention relates to a socket intended to equip a multicore cable K and for example according to ISO IEC 11 801, this socket comprising at least one removable comb 1, a connection terminal block 2 and clamping means such as 3 and 4.

Le peigne 1 est traversé par un canal central 5 destiné à offrir un passage au câble K suivant un axe longitudinal X de la prise.The comb 1 is traversed by a central channel 5 intended to provide a passage to the cable K along a longitudinal axis X of the socket.

Ce peigne présente, sur une face frontale 10, des entailles 11 disposées autour du canal central 5, chaque entaille 11 étant dimensionnée pour maintenir un conducteur isolé C correspondant du câble K.This comb has, on a front face 10, notches 11 arranged around the central channel 5, each notch 11 being dimensioned to maintain an insulated conductor C corresponding to the cable K.

Le bornier 2 est adapté à recevoir une fiche amovible multiconductrice et comprend par exemple à cette fin un logement axial 24 servant de réceptacle pour une telle fiche (figures 8 et 9).The terminal block 2 is adapted to receive a removable multicore plug and comprises for example for this purpose an axial housing 24 serving as a receptacle for such a plug ( figures 8 and 9 ).

Ce bornier 2 présente, à l'opposé du logement axial 24, une face frontale 20 qui, en configuration montée de la prise, est disposée en regard de la face frontale 10 du peigne 1 et immédiatement adjacente à cette face 10.This terminal 2 has, opposite the axial housing 24, a front face 20 which, in the mounted configuration of the socket, is disposed facing the front face 10 of the comb 1 and immediately adjacent to this face 10.

Le bornier 2 comprend, sur la face frontale 20, des contacts électriques autodénudants 21 dont chacun est adapté à recevoir un conducteur isolé correspondant C du câble K.The terminal block 2 comprises, on the front face 20, insulation displacement electrical contacts 21 each of which is adapted to receive a corresponding insulated conductor C of the cable K.

Chacun des contacts 21 comporte de façon connue une paire de lames métalliques pour pouvoir dénuder le conducteur isolé C qui lui correspond, et qui est maintenu dans une entaille 11 du peigne 1, grâce à un mouvement relatif de ce contact 21 et de ce conducteur isolé C, effectué lors d'une phase de montage de la prise.Each of the contacts 21 comprises, in known manner, a pair of metal blades to be able to strip the corresponding insulated conductor C which corresponds to it, and which is held in a notch 11 of the comb 1, thanks to a relative movement of this contact 21 and this isolated conductor. C, performed during a mounting phase of the socket.

Les moyens de serrage sont essentiellement constitués par un dispositif d'assemblage traversé par le canal central 5, ce dispositif d'assemblage comprenant une vis 3 et un écrou 4, et ayant notamment pour fonction d'opérer, lors de la phase de montage, le mouvement relatif de chaque contact 21 et de chaque conducteur isolé C correspondant.The clamping means consist essentially of an assembly device traversed by the central channel 5, this assembly device comprising a screw 3 and a nut 4, and having the particular function of operating, during the mounting phase, the relative movement of each contact 21 and each insulated conductor C corresponding.

Dans une prise conforme à l'invention, la vis 3 est montée solidaire du peigne 1 en translation axiale et à libre rotation par rapport au peigne 1 autour de l'axe X.In a socket according to the invention, the screw 3 is mounted integral with the comb 1 in axial translation and free rotation relative to the comb 1 about the axis X.

Par exemple (figure 8), le peigne 1 comporte une cheminée cylindrique 13 sur laquelle la vis 3 est enfilée à force axialement, cette cheminée présentant un rebord 130 radialement élastique qui maintient la vis prisonnière le long de l'axe longitudinal X.For example ( figure 8 ), the comb 1 comprises a cylindrical chimney 13 on which the screw 3 is threaded axially, this chimney having a radially elastic rim 130 which holds the screw captive along the longitudinal axis X.

Par ailleurs, le bornier 2 comprend plusieurs colonnes, par exemple deux colonnes 22, qui font saillie axialement de la face frontale 20 de ce bornier 2 et qui remplissent avantageusement deux fonctions au moins.Furthermore, the terminal block 2 comprises several columns, for example two columns 22, which protrude axially from the end face 20 of this terminal block 2 and which advantageously serve at least two functions.

Tout d'abord, ces colonnes 22 présentent des encoches hélicoïdales 41, pratiquées radialement dans ces colonnes, et qui, ensemble, constituent l'écrou 4 ou participent à sa constitution.First, these columns 22 have helical notches 41, made radially in these columns, and which together constitute the nut 4 or participate in its constitution.

D'autre part, une ou plusieurs des colonnes 22 forment de préférence une butée de rotation, propre à bloquer la rotation du peigne 1 autour de l'axe X.On the other hand, one or more of the columns 22 preferably form a stop of rotation, able to block the rotation of the comb 1 about the axis X.

Grâce à cet agencement, la prise avant montage ne présente que deux sous-ensembles dont chacun peut être tenu dans une main de l'opérateur, l'assemblage de ces deux-sous-ensembles étant réalisé de façon aisée sans nécessité de prendre des mesures spécifiques pour éviter la rotation du peigne 1 par rapport au bornier 2.Thanks to this arrangement, the plug before assembly has only two subassemblies, each of which can be held in one hand of the operator, the assembly of these two subassemblies being made easily without the need to take measurements. specific to avoid the rotation of the comb 1 with respect to the terminal block 2.

Comme le montrent notamment les figures 6 et 8, les entailles 11 débouchent sur des faces libres 12 du peigne 1, qui sont constituées par des faces latérales, adjacentes à la face frontale 10 du peigne 1 et perpendiculaires à cette face 10.As shown in particular by figures 6 and 8 , the notches 11 open on free faces 12 of the comb 1, which are constituted by lateral faces, adjacent to the front face 10 of the comb 1 and perpendicular to this face 10.

Grâce à cette disposition, les conducteurs isolés C débordant de ces faces 12 peuvent être aisément sectionnés après montage de la prise.With this arrangement, the insulated conductors C protruding from these faces 12 can be easily cut after mounting the socket.

Comme le montrent bien les figures 2 et 3, la vis 3 comprend plusieurs rampes hélicoïdales 31 de développement angulaire limité, par exemple deux rampes hélicoïdales dont chacune présente un développement angulaire d'environ un demi tour, c'est-à-dire 180 degrés.As the figures 2 and 3 , the screw 3 comprises several helical ramps 31 of limited angular development, for example two helical ramps each of which has an angular development of about a half turn, that is to say 180 degrees.

Chacune de ces rampes 31 est conformée pour pouvoir s'engager, en phase de montage de la prise et par un mouvement de rotation de la vis 3, dans une encoche hélicoïdale 41 correspondante d'une colonne 22.Each of these ramps 31 is shaped to be able to engage, in the mounting phase of the socket and by a rotational movement of the screw 3, in a corresponding helical notch 41 of a column 22.

L'application d'un couple de rotation sur la vis 3 est facilitée en prévoyant sur cette vis des reliefs de préhension 32 disposés de part et d'autre de l'axe X et faisant saillie axialement dans une direction qui s'éloigne de la face frontale 10.The application of a rotational torque on the screw 3 is facilitated by providing on this screw gripping reliefs 32 disposed on either side of the axis X and projecting axially in a direction away from the front face 10.

Comme le montre la figure 2, la vis 3 peut aussi présenter une collerette 30 dotée d'un ou plusieurs reliefs radiaux 300, chaque relief 300 étant propre à coopérer avec l'arête 220 (figure 1) d'une colonne 22 correspondante pour permettre un encliquetage réversible de la vis 3 par rapport à cette colonne à la fin de la phase de montage.As shown in figure 2 , the screw 3 may also have a flange 30 provided with one or more radial reliefs 300, each relief 300 being adapted to cooperate with the edge 220 ( figure 1 ) of a corresponding column 22 to allow a reversible snap of the screw 3 relative to this column at the end of the mounting phase.

De préférence, l'écrou 4 est aussi partiellement constitué par les faces d'extrémité 42 des colonnes 22.Preferably, the nut 4 is also partially constituted by the end faces 42 of the columns 22.

Ces faces d'extrémité 42, qui sont alors hélicoïdales et parallèles aux encoches 41, servent d'appui, dans une phase de démontage de la prise, aux faces internes respectives des rampes hélicoïdales 31 de la vis 3, et facilitent ainsi considérablement ce démontage.These end faces 42, which are then helical and parallel to the notches 41, serve support, in a disassembly phase of the socket, to the respective inner faces of the helical ramps 31 of the screw 3, and thus greatly facilitate this disassembly.

Pour éviter toute erreur lors du montage de la prise, un détrompeur 23 peut être disposé sur la face frontale 20 du bornier 2, ce détrompeur coopérant par exemple avec une face latérale particulière 123 du peigne 1, et n'autorisant l'assemblage du peigne 1 et du bornier 2 que dans une seule position angulaire relative autour de l'axe X.To avoid any error during the mounting of the socket, a polarizer 23 may be disposed on the end face 20 of the terminal block 2, this polarizer cooperating for example with a particular side face 123 of the comb 1, and allowing the assembly of the comb 1 and the terminal block 2 only in a single relative angular position about the axis X.

Dans une forme d'exécution industriellement optimisée de l'invention, le peigne 1, le bornier 2, la vis 3, ou l'une au moins de ces pièces peuvent être réalisées au moins en partie par moulage d'un matériau thermoplastique.In an industrially optimized embodiment of the invention, the comb 1, the terminal block 2, the screw 3, or at least one of these parts can be made at least in part by molding a thermoplastic material.
