Description

La présente invention a trait à un dispositif de raccordement d'une antenne, notamment pour véhicule auto­mobile, avec son câble coaxial associé.The present invention relates to a device for connecting an antenna, in particular for a motor vehicle, with its associated coaxial cable.

On sait que les véhicules automobiles, qui sont équipés de poste autoradio, portent généralement une antenne extérieure qu'il convient de relier par un câble au poste récepteur radio. Pour éviter le parasitage des réceptions, le câble que l'on utilise est un câble coaxial qui comporte une gaine externe de protection à l'intérieur de laquelle se trouve une gaine interne, une tresse de masse étant disposée entre les deux gaines ; dans la gaine interne est placé un fil électroconducteur qui constitue l'âme du câble et qui est relié à l'antenne réceptrice d'une part, et au poste récepteur radio, d'autre part ; l'anti-parasitage des signaux transportés par l'âme du câble est assuré par la tresse métallique que l'on relie à la masse du véhicule. Un tel câble est généralement relié à l'antenne par un connecteur constitué par une bague en matière plastique dont une base porte une rondelle formant cosse de masse et dont l'autre base porte un disque formant cosse d'an­tenne ; le connecteur est fixé à la carrosserie par un boulon solidaire de l'antenne extérieure, ledit boulon tra­versant la carrosserie et la bague du connecteur ; la cosse d'antenne est serrée par l'écrou du boulon et la cosse de masse est appliquée contre la face interne de la carrosserie du véhicule, l'embase de l'antenne se trouvant sur la face externe de ladite carrosserie, au droit du boulon de fixa­tion. La cosse de masse comporte une patte grâce à laquelle on assure par sertissage la liaison mécanique entre le câ­ble et le connecteur ; ce sertissage s'effectue sur la tresse de masse du câble,que l'on a retournée à l'extérieur dudit câble au niveau où il doit s'effectuer : on assure ainsi la mise à la masse de la tresse du câble. Entre ce premier sertissage et la bague plastique du connecteur, la gaine interne du câble est dénudée, de sorte qu'il peut y avoir un parasitage des réceptions radio à ce niveau ; on a donc déjà proposé, par exemple dans la demande de brevet français 2 563 946 , d'effectuer sur la gaine interne un deuxième sertissage au moyen de deux ailes prévues à cet effet sur la patte de sertissage de la cosse de masse et de coiffer le connecteur jusqu'au niveau de ce deuxième sertissage par un capuchon métallique qui recouvre la zone où l'âme du câble est liée électriquement à la cosse d'antenne du connecteur.It is known that motor vehicles, which are fitted with a radio unit, generally carry an external antenna which should be connected by cable to the radio receiver unit. To avoid interference from reception, the cable that is used is a coaxial cable which has an external protective sheath inside of which is an internal sheath, a ground braid being disposed between the two sheaths; in the internal sheath is placed an electroconductive wire which constitutes the core of the cable and which is connected to the receiving antenna on the one hand, and to the radio receiving station, on the other hand; anti-interference signals transmitted by the cable core is provided by the metal braid that is connected to the vehicle ground. Such a cable is generally connected to the antenna by a connector constituted by a plastic ring, one base of which carries a washer forming a ground terminal and the other base of which carries a disc forming an antenna terminal; the connector is fixed to the body by a bolt secured to the external antenna, said bolt passing through the body and the ring of the connector; the antenna lug is tightened by the bolt nut and the earth lug is applied against the internal face of the vehicle body, the antenna base being on the external face of said body, in line with the fixing bolt. The ground lug has a tab thanks to which the mechanical connection between the cable and the connector is ensured by crimping; this crimping is carried out on the ground braid of the cable, which has been turned outside of said cable at the level where it is to be carried out: this ensures the grounding of the braid of the cable. Between this first crimping and the plastic ring of the connector, the internal sheath of the cable is stripped, so that there can be interference from radio reception at this level; it has therefore already been proposed, for example in French patent application 2,563,946, to perform a second crimping on the internal sheath by means of two wings provided for this purpose on the crimping lug of the earth terminal and to cap the connector up to the level of this second crimping by a metal cap which covers the area where the cable core is electrically linked to the antenna terminal of the connector.

Dans un tel dispositif de l'état de la technique, la liaison électrique entre l'âme du câble et la cosse d'antenne du connecteur est assurée par une soudure de l'âme sur la cosse d'antenne. Cette technique exige, par conséquent, que l'on découpe la gaine interne du câble de façon à laisser sortir une certaine longueur du fil qui constitue l'âme et que l'on soude ensuite ce fil sur la cosse d'antenne du connecteur. Une opération supplémentaire est d'ailleurs nécessaire en raison du fait que l'âme du câble est un fil très fin qui, à l'intérieur de la gaine interne, doit être soutenu par un élément-support ; selon une première technique, l'élément-support est un jonc plas­tique, qui est enroulé selon une hélice à très large pas autour du fil constitutif de l'âme de façon à le maintenir sensiblement selon l'axe de la gaine ; selon une deuxième technique, la gaine interne est remplie d'une mousse plas­tique,qui forme l'élément-support de l'âme. Dans les deux cas, il faut séparer de l'âme l'élément-support précité pour pouvoir effectuer correctement la soudure de l'âme sur la cosse d'antenne. On voit donc que la réalisation de la liaison électrique entre l'âme du câble et la cosse d'an­tenne du connecteur est une opération qui se prête extrême­ment mal à l'automatisation.In such a device of the prior art, the electrical connection between the core of the cable and the antenna terminal of the connector is ensured by welding the core to the antenna terminal. This technique therefore requires that the internal sheath of the cable be cut so as to let out a certain length of the wire which constitutes the core and that this wire is then welded to the antenna terminal of the connector. An additional operation is moreover necessary due to the fact that the core of the cable is a very fine wire which, inside the internal sheath, must be supported by a support element; according to a first technique, the support element is a plastic rod, which is wound in a very wide pitch helix around the wire constituting the core so as to maintain it substantially along the axis of the sheath; according to a second technique, the internal sheath is filled with a plastic foam, which forms the support element of the core. In both cases, the aforementioned support element must be separated from the core in order to be able to correctly weld the core to the antenna terminal. It can therefore be seen that making the electrical connection between the cable core and the antenna terminal of the connector is an operation which lends itself extremely poorly to automation.

La présente invention a pour but de proposer un dispositif de raccordement d'une antenne avec son câble coaxial associé qui permette de supprimer l'opération de soudure, qui était jusqu'alors nécessaire pour assurer la liaison électrique entre l'âme et la cosse d'antenne du connecteur. La suppression de la soudure permet également d'éviter d'avoir à enlever l'élément-support dans la zone de soudure et l'on peut dès lors facilement envisager un procédé automatique pour réaliser la liaison du câble coaxial avec son connecteur associé.The object of the present invention is to provide a device for connecting an antenna with its associated coaxial cable which eliminates the soldering operation, which was previously necessary to ensure the electrical connection between the core and the antenna terminal of the connector. The elimination of the weld also makes it possible to avoid having to remove the support element in the weld zone and it is therefore easy to envisage an automatic method for making the connection of the coaxial cable with its associated connector.

Selon l'invention, on réalise la liaison élec­trique avec un élément de contact qui est introduit dans la gaine interne du câble et en prévoyant, dans la zone d'espace où l'âme et l'élément de contact sont en vis-à-vis, au moins une protubérance . On peut,en outre, effectuer un sertissage dans ladite zone d'espace ; au moment du sertissage et quelle que soit la position de l'âme par rapport à l'élé­ment de contact à l'intérieur de la gaine interne, l'écrase­ment dû au sertissage vient appliquer l'âme du câble sur l'élément de contact. L'élément-support ne constitue pas une gêne pour le contact électrique en raison du fait que cet élément-support peut fluer dans les creux, de part et d'autre de la protubérance, sous l'effet de la pression de sertissage, ce qui ne serait pas le cas si l'on ne prévoyait pas dans cette zone au moins une protubérance.According to the invention, the electrical connection is made with a contact element which is introduced into the internal sheath of the cable and by providing, in the area of space where the core and the contact element are opposite. screw, at least one protuberance. It is also possible to crimp in said space zone; at the time of crimping and whatever the position of the core relative to the contact element inside the internal sheath, the crushing due to crimping applies the core of the cable to the contact element . The support element does not constitute a hindrance for the electrical contact due to the fact that this support element can creep in the hollows, on either side of the protuberance, under the effect of the crimping pressure, this which would not be the case if at least one protuberance was not provided in this area.

Bien entendu, pour assurer la fiabilité de la liaison électrique, qui peut être obtenue même sans sertissage au niveau de ladite zone d'espace, on préfère prévoir une succession de protubérances séparées les unes des autres par des zones de creux, l'élément de contact ayant des dimensions suffisantes pour que l'âme du câble soit appuyée contre lui ; de même pour que les protubérances puissent jouer leur rôle de façon optimale, on prévoit que, vues en plan, elles s'étendent sur la majeure partie de la zone concernée.Of course, to ensure the reliability of the electrical connection, which can be obtained even without crimping at the level of said space zone, it is preferred to provide a succession of protuberances separated from each other by hollow zones, the element of contact having sufficient dimensions for the cable core to be pressed against it; Similarly, so that the protrusions can play their role optimally, it is expected that, seen in plan, they extend over most of the area concerned.

On a constaté qu'en mettant en oeuvre un disposi­tif de raccordement selon l'invention, on pouvait avec fiabilité, assurer la liaison électrique entre l'âme d'un câble coaxial et la cosse d'antenne d'un connecteur du type ci-dessus indiqué. Etant donné qu'avec le dispositif selon l'invention, les liaisons électriques, tant pour la tresse de masse que pour l'âme, sont obtenues par insertion de l'élément de contact, éventuellement combinée avec un sertissage, il est extrêmement aisé d'automatiser le procédé de fabrication, ce qui conduit à des prix de revient considérablement abaissés.It was found that by implementing a connection device according to the invention, it was possible to reliably ensure the electrical connection between the core of a coaxial cable and the antenna terminal of a connector of the type indicated above. Given that with the device according to the invention, the electrical connections, both for the ground braid and for the core, are obtained by insertion of the contact element, possibly combined with crimping, it is extremely easy to 'automate the manufacturing process, which leads to considerably lower cost prices.

La présente invention a, en conséquence,pour objet, le produit industriel nouveau que constitue un dispositif de raccordement d'une antenne, notamment pour véhicule au­tomobile, avec son câble coaxial associé, ledit câble coaxial comportant une gaine externe, qui renferme une gai­ne interne entourée d'une tresse de masse, ladite gaine interne renfermant une âme conductrice soutenue par un élément-support, ladite âme étant reliée électriquement à l'antenne par une cosse d'antenne, ladite tresse de masse étant reliée électriquement à la masse par une cosse de masse, les cosses d'antenne et de masse étant montées sur une bague isolante pour former un connecteur d'antenne, la tresse de masse étant rabattue à l'extérieur de la gaine externe du câble au niveau d'un premier sertissage de la cosse de masse sur ledit câble, ladite cosse de masse for­mant, en outre, un entourage de l'âme dans une zone comprise entre le premier sertissage et la bague isolante du connec­teur, cet entourage assurant l'anti-parasitage jusqu'au voi­sinage immédiat de la cosse d'antenne, caractérisé par le fait que la cosse d'antenne est associée à un élément de contact, qui lui est lié électriquement et qui pénètre dans la gaine interne, la zone d'espace, où l'élément de contact et l'âme sont en vis-à-vis, comportant au moins une protubérance pratiquée sur l'une des parois délimitant ladite zone d'espace, ladite protubérance assurant le con­tact électrique entre l'âme du câble et l'élément de contact et s'étendant, vue en plan, sur la majeure partie dudit élément de contact.The present invention therefore has as its object the new industrial product that constitutes an antenna connection device, in particular for a motor vehicle, with its associated coaxial cable, said coaxial cable comprising an external sheath, which contains an internal sheath surrounded by a ground braid, said internal sheath containing a conductive core supported by a support element, said core being electrically connected to the antenna by an antenna terminal, said ground braid being electrically connected to ground by a ground lug, the antenna and ground lugs being mounted on an insulating ring to form an antenna connector, the ground braid being folded down outside the outer sheath of the cable at a first crimping of the ground lug on said cable, said ground lug further forming an entourage of the core in an area between the first crimping and the insulating ring of the connector, this entourage ensuring the anti-interference to the immediate vicinity of the antenna terminal, characterized in that the antenna terminal is associated with a contact element, which is electrically linked to it and which penetrates into the internal sheath, the area of space, where the contact element and the core face each other, comprising at least one protuberance formed on one of the walls delimiting said space zone, said protuberance ensuring the electrical contact between the soul of the cable and the contact element and extending, in plan view, over the major part of said contact element.

L'élément de contact peut pénétrer dans la gaine interne au niveau d'une zone de sertissage, la zone d'espace où l'élément de con­tact et l'âme sont en vis-à-vis subissant un sertissage.The contact element can penetrate the internal sheath at a crimping zone, the space zone where the contact element and the core face each other undergoing crimping.

De préférence, cet élément de contact a, dans un plan per­pendiculaire à l'axe de la gaine interne, au moins pour sa partie qui pé­nètre dans ladite gaine interne, une dimension (largeur) déterminée de manière à permettre un coincement de l'àme du conducteur, et le cas échéant, du jonc plastique formant élément-support, par la gaine interne qui peut être déformée ou non. Cette dimension peut être légèrement in­férieure au diamètre interne de la gaine.Preferably, this contact element has, in a plane perpendicular to the axis of the internal sheath, at least for its part which penetrates into said internal sheath, a dimension (width) determined so as to allow jamming of the core. of the conductor, and where appropriate, of the plastic rod forming the support element, by the internal sheath which may or may not be deformed. This dimension may be slightly less than the internal diameter of the sheath.

On peut prévoir que l'entourage entre la zone du premier ser­tissage et la bague isolante du connecteur, ou bien forme un tunnel autour de l'âme, ou bien forme un second sertissage.Provision may be made for the surround between the zone of the first crimping and the insulating ring of the connector, either to form a tunnel around the core, or else to form a second crimping.

On peut prévoir également que la (ou les) protubérance (s) soi(en)t formée (s) ou bien sur l'élément de contact, ou bien sur la gaine interne.Provision may also be made for the protuberance (s) to be formed either on the contact element or on the internal sheath.

Selon une première variante de réalisation, l'élément de contact est solidaire de la cosse d'antenne.According to a first alternative embodiment, the contact element is integral with the antenna terminal.

Selon un premier mode de réalisation de ladite première va­riante, l'élément de contact est une partie de la cosse d'antenne, les deux étant obtenus d'une seule pièce. On peut prévoir que l'élément de contact soit une languette ondulée ; on peut aussi prévoir que l'élément de contact forme un tube obtenu par pliage, les parois du tube ayant été matricées avant pliage pour former une succession de protubérances et de creux à l'intérieur du tube. On peut également envisager de réaliser l'élément de contact sous forme d'une languette quelconque et de faire en sorte que les poinçons du second sertissage comportent des bossages faisant apparaî­tre sur la gaine interne, au moment du sertissage, au moins une protubérance en direction de l'âme du câble.According to a first embodiment of said first variant, the contact element is a part of the antenna terminal, the two being obtained in one piece. Provision may be made for the contact element to be a wavy tongue; one can also provide that the contact element forms a tube obtained by bending, the walls of the tube having been stamped before folding to form a succession of protuberances and hollows inside the tube. It is also conceivable to produce the contact element in the form of any tongue and to ensure that the punches of the second crimping include bosses making appear on the internal sheath, at the time of crimping, at least one protuberance in the direction of the cable core.

Selon un deuxième mode de réalisation de la première variante, l'élément de contact est une pièce rapportée sur la cosse d'antenne. Dans ce cas, l'élément de contact peut être une tige comportant des ondulations de surface et ayant sa tête fixée sur la cosse d'antenne.According to a second embodiment of the first variant, the contact element is an insert on the antenna terminal. In this case, the contact element may be a rod having surface undulations and having its head fixed on the antenna terminal.

Avantageusement, dans le cas où l'élément-support est un jonc plastique enroulé en hélice autour du fil constitutif de l'âme, l'élément de contact, formé par une languette ou une tige ondulée, a une longueur supérieure au pas de l'hélice formée par le jonc plastique.Advantageously, in the case where the support element is a plastic rod wound in a helix around the constituent wire of the core, the contact element, formed by a tongue or a wavy rod, has a length greater than the pitch of the helix formed by the plastic rod.

Selon une deuxième variante du dispositif selon l'invention, l'élément de contact est un manchon éléctro­conducteur indépendant de la cosse d'antenne, dont une premiè­re partie pénètre dans la gaine interne au droit du premier sertissage et comporte intérieurement au moins une protubé­rance, l'âme du câble venant à l'intérieur de ladite première partie du manchon, et dont une seconde partie est disposée au droit de l'entourage et reçoit intérieurement une patte de liaison solidaire de la cosse d'antenne ; la patte de liaison de la cosse d'antenne peut former une seule pièce avec ladite cosse ; le manchon peut être constitué d'une tô­le matricée pliée pour obtenir une forme sensiblement cylin­drique ; la partie du manchon, qui se trouve au droit de l'entourage, est recouverte par un fourreau isolant et subit un sertissage donnant naissance à un second sertissage. Dans une variante, la partie du manchon, qui se trouve au droit de l'entourage, est enfichée sur la patte de liaison, le dispositif ne comportant, dès lors, qu'un seul sertissage et le fourreau isolant n'étant pas nécessaire.According to a second variant of the device according to the invention, the contact element is an electrically conductive sleeve independent of the antenna terminal, a first part of which penetrates into the internal sheath in line with the first crimping and internally comprises at least one protuberance, the core of the cable coming inside said first part of the sleeve, and a second part of which is disposed in line with the surround and receives internally a connecting lug secured to the antenna terminal; the connecting lug of the antenna terminal can form a single piece with said terminal; the sleeve may consist of a bent stamped sheet to obtain a substantially cylindrical shape; the part of the sleeve, which is in line with the surround, is covered by an insulating sheath and undergoes crimping giving rise to a second crimping. In a variant, the part of the sleeve, which is located in line with the surround, is plugged into the connection tab, the device therefore comprising only one crimping and the insulating sheath not being necessary.

Tous les modes de réalisation ci-dessus envisa­gés sont utilisables lorsque l'élément-support de l'âme du câble est un jonc en matière plastique. Dans le cas où l'élément-support de l'âme du câble est un remplissage de mousse,qui occupe tout le volume intérieur libre de la gaine interne, on préfère utiliser un mode de réalisation dans lequel l'élément de contact a une forme tubulaire, qu'il soit ou non solidaire de la cosse d'antenne ; en effet, l'introduction d'un tel élément de contact dans la gaine interne permet de repousser ou de perforer la mousse qui constitue l'élé­ment-support et, par conséquent, de dénuder l'âme du câble qui vient se placer à l'intérieur du tube ou manchon cons­ tituant l'élément de contact. On peut prévoir que la partie de l'élément de contact,qui pénètre dans la gaine interne, ait une extrémité en forme de biseau pour faciliter son intro­duction dans la gaine interne.All the above embodiments envisaged can be used when the support element of the cable core is a plastic rod. In the case where the support element of the cable core is a foam filling, which occupies the entire free internal volume of the internal sheath, it is preferred to use an embodiment in which the contact element has a shape tubular, whether or not integral with the antenna terminal; indeed, the introduction of such a contact element into the internal sheath makes it possible to repel or perforate the foam which constitutes the support element and, consequently, to strip the core of the cable which is placed at the inside the tube or sleeve cons tituant the contact element. Provision may be made for the part of the contact element which penetrates the internal sheath to have a bevel-shaped end to facilitate its introduction into the internal sheath.

Le dispositif selon l'invention peut être avanta­geusement utilisé avec un connecteur du type de celui qui est décrit dans la demande de brevet français 2 563 946. Dans ce cas, la bague du connecteur a une forme sensiblement cyclindrique, l'une de ses bases étant recouverte par une rondelle qui forme la cosse de masse et l'autre par un dis­que qui forme la cosse d'antenne, l'ensemble étant recou­vert par un capuchon métallique d'anti-parasitage fixé sur des pat­tes reliées électriquement à la cosse de masse. Le connecteur peut être fixé sur une carrosserie de véhicule automobile par un bou­lon,qui traverse la bague de connecteur selon son axe et qui est lié électriquement et mécaniquement à l'antenne exté­rieure du véhicule, l'écrou du boulon prenant appui sur la cosse d'antenne alors que la cosse de masse porte des indentations qui sont écrasées contre la carrosserie par le serrage du boulon.The device according to the invention can advantageously be used with a connector of the type described in French patent application 2,563,946. In this case, the connector ring has a substantially cylindrical shape, one of its bases being covered by a washer which forms the ground terminal and the other by a disc which forms the antenna terminal, the assembly being covered by a metal anti-interference cap fixed on legs electrically connected to the terminal mass. The connector can be fixed to a motor vehicle body by a bolt, which passes through the connector ring along its axis and which is electrically and mechanically linked to the external antenna of the vehicle, the nut of the bolt resting on the terminal d antenna while the ground lug carries indentations which are crushed against the bodywork by tightening the bolt.

Pour mieux faire comprendre l'objet de l'inven­tion, on va en décrire maintenant,à titre d'exemples pure­ment illustratifs et non limitatifs, plusieurs modes de réa­ lisation représentés sur le dessin annexé.To better understand the object of the invention, we will now describe, by way of purely illustrative and nonlimiting examples, several modes of reaction. reading shown in the accompanying drawing.

En se référant aux figures 1 à 4, on voit que l'on a désigné par 1 la carrosserie d'un véhicule automobile qui porte une embase d'antenne 2 ; le brin d'antenne a été désigné par 3 et il est relié électriquement dans l'embase 2 à un boulon 4,qui permet la fixation de l'antenne sur la carrosserie et la fixation simultanée du connecteur cor­respondant. Ce connecteur comporte une bague en matière plastique 5 de forme sensiblement cylindrique ; sur la base de cette bague 5,qui est en vis-à-vis de la carrosserie 1, est disposée une rondelle 6 qui constitue la cosse de masse ; la cosse de masse 6 porte des indentations 7 et elle se prolonge par une patte de sertissage 8 comportant successivement deux paires d'ailes de sertissage à savoir les ailes de sertissage 9,qui sont les plus éloignées de la bague 5, et les ailes de sertissage 10, qui sont les plus rapprochées. Sur celle de ses bases qui n'est pas occupée par la cosse d'antenne 6, la bague 5 porte une rondelle 11, qui se prolonge parallèlement à l'axe de la bague 5 par une patte 12,dont l'extrémité est repliée en équerre pour constituer l'élément de contact 13. Le connecteur constitué par l'ensemble 5, 6, 11 est retenu au-dessous de l'embase 2 au moyen du boulon 4 dont l'écrou 4a vient serrer le con­necteur, par l'intermédiaire d'une rondelle élastique 14, contre la carrosserie automobile 1, de façon que les inden­tations 7 de la cosse de masse 6 assurent un bon contact de la cosse 6 avec la masse du véhicule.Referring to Figures 1 to 4, we see that we have designated by 1 the body of a motor vehicle which carries an antenna base 2; the antenna strand has been designated by 3 and it is electrically connected in the base 2 to a bolt 4, which allows the attachment of the antenna to the bodywork and the simultaneous attachment of the corresponding connector. This connector comprises a plastic ring 5 of substantially cylindrical shape; on the base of this ring 5, which faces the body 1, a washer 6 is arranged which constitutes the ground terminal; the ground lug 6 carries indentations 7 and it is extended by a crimping lug 8 successively comprising two pairs of crimping wings, namely the crimping wings 9, which are the furthest from the ring 5, and the wings of crimping 10, which are the closest. On that of its bases which is not occupied by the antenna terminal 6, the ring 5 carries a washer 11, which extends parallel to the axis of the ring 5 by a lug 12, the end of which is folded at right angles to constitute the contact element 13. The connector constituted by the assembly 5, 6, 11 is retained below the base 2 by means of the bolt 4, the nut 4 a of which tightens the connector, by by means of an elastic washer 14, against the automobile body 1, so that the indentations 7 of the ground terminal 6 ensure good contact of the terminal 6 with the mass of the vehicle.

Le connecteur assure la liaison entre l'antenne et le câble coaxial désigné par 15 dans son ensemble. Le câble 15 comporte une gaine externe 16, qui renferme une gaine interne coaxiale 17 ; entre les deux gaines est dis­posée une tresse métallique 20 ; à l'intérieur de la gaine interne 17 se trouve un fil électroconducteur,qui constitue l'âme 18 du câble ; ce fil étant très fin, il est renforcé mécaniquement par un élément-support constitué par un jonc de matière plastique 19 ; le jonc 19 est enroulé, selon une hélice à grand pas,autour de l'âme 18. La tresse métallique 20 assure l'anti-parasitage ; à l'extrémité du câble 15 qui est relié au connecteur, la gaine externe 16 est coupée de façon à dénuder une partie de la gaine interne 17 et la tresse métallique 20 est retournée sur l'extérieur de la gaine externe 16.The connector provides the link between the antenna and the coaxial cable designated by 15 as a whole. The cable 15 comprises an external sheath 16, which contains a coaxial internal sheath 17; between the two sheaths is disposed a metal braid 20; inside the internal sheath 17 is an electrically conductive wire, which constitutes the core 18 of the cable; this wire being very thin, it is mechanically reinforced by a support element constituted by a plastic rod 19; the rod 19 is wound, according to a helix with large pitch, around the core 18. The metal braid 20 provides anti-interference; at the end of the cable 15 which is connected to the connector, the external sheath 16 is cut so as to strip part of the internal sheath 17 and the metal braid 20 is turned over on the outside of the external sheath 16.

Les ailes de sertissage 9 de la cosse de masse 6 sont refermées pour former un manchon cylindrique avant même que l'on utilise la cosse de masse pour constituer le connecteur. Le connecteur est alors monté en assemblant les pièces 6, 5 et 11, la languette qui constitue l'élément de contact 13 passant entre les ailes 10,qui n'ont pas encore été refermées. On présente alors l'extrémité du câble 15, qui a été préparé comme ci-dessus indiqué, en l'enfilant dans le cylindre formé par les ailes 9 préalablement cintrées. L'extrémité de la gaine externe 16 vient se loger dans le cylindre formé par les ailes 9 ; la gaine interne 17 vient se loger entre les ailes 10, la languette 13 pénétrant à l'intérieur de la gaine interne 17. Dans cette réalisation, on voit que la languette 13 a une forme sensiblement rectan­gulaire,dont la largeur est légèrement inférieure au dia­mètre interne de la gaine interne 17 ; sur toute sa largeur, la languette 13 comporte des ondulations, qui font apparaî­tre une succession de sommets ou protubérances 13a et de creux 13b . Au moment où la languette 13 s'introduit dans la gaine interne 17, la position de l'âme 18 par rapport à la languette 13 est aléatoire. L'état des différentes pièces du dispositif selon l'invention en ce point du monta­ge est représenté sur la figure 2.The crimping wings 9 of the ground lug 6 are closed to form a cylindrical sleeve even before the ground lug is used to form the connector. The connector is then mounted by assembling the parts 6, 5 and 11, the tongue which constitutes the contact element 13 passing between the wings 10, which have not yet been closed. The end of the cable 15, which has been prepared as above indicated, is then presented by threading it into the cylinder formed by the wings 9 previously bent. The end of the outer sheath 16 is received in the cylinder formed by the wings 9; the internal sheath 17 is housed between the wings 10, the tongue 13 penetrating inside the internal sheath 17. In this embodiment, it can be seen that the tongue 13 has a substantially rectangular shape, the width of which is slightly less than the diameter internal of the internal sheath 17; over its entire width, the tongue 13 has undulations, which reveal a succession of vertices or protuberances 13 a and hollows 13 b . When the tongue 13 is introduced into the internal sheath 17, the position of the core 18 relative to the tongue 13 is random. The state of the different parts of the device according to the invention at this point in the assembly is shown in FIG. 2.

On procède alors aux sertissages. Le premier ser­tissage est opéré sur les ailes 9 et assure le contact entre la tresse de masse 20,retournée à l'extérieur de la gaine externe 16,et la cosse de masse 6. Le second ser­tissage s'effectue sur les ailes 10, qui sont refermées autour de la gaine interne 17. Sous la pression de sertissa­ge, le jonc plastique 19 flue dans les creux 13b et l'âme 18 du câble vient se bloquer entre les protubérances 13a et la gaine interne 17, elle-même serrée par les ailes 10. On assure ainsi de façon parfaitement fiable la liaison élec­trique de l'âme 18 avec la cosse d'antenne 11. En outre, les ailes 10 complètent l'anti-parasitage dans la zone où la gaine interne 17 n'est plus entourée par la tresse de masse 20. L'anti-parasitage est complété, de façon connue, en coiffant la totalité du connecteur au moyen d'un capuchon métallique 21, qui vient se clipser sur des pattes 22 reliées électriquement à la cosse de masse 6.We then proceed to crimping. The first crimping is carried out on the wings 9 and ensures contact between the ground braid 20, returned to the outside of the outer sheath 16, and the grounding lug 6. The second crimping is carried out on the wings 10, which are closed around the internal sheath 17. Under the crimping pressure, the plastic rod 19 flows in the recesses 13 b and the core 18 of the cable is blocked between the protrusions 13 a and the internal sheath 17, itself tightened by the wings 10. The electrical connection of the core 18 with the antenna terminal 11 is thus provided in a completely reliable manner. In addition, the wings 10 complete the anti-interference in the area where the internal sheath 17 does not is more surrounded by the ground braid 20. The anti-interference is supplemented, in a known manner, by covering the entire connector by means of a metal cap 21, which is clipped onto tabs 22 electrically connected to the terminal mass 6.

On voit que les liaisons électriques du connecteur avec le câble d'antenne ont été réalisées uniquement par sertissage, ce qui permet d'automatiser le procédé de liai­son du câble avec son connecteur associé et ce qui permet, par conséquent,de réduire le prix de revient de ce sous-­ensemble.It can be seen that the electrical connections of the connector with the antenna cable were made only by crimping, which makes it possible to automate the process of connecting the cable with its associated connector and which therefore makes it possible to reduce the price of comes back from this subset.

Sur la figure 5, on a représenté un autre mode de réalisation de la languette,qui constitue l'élément de con­tact de la cosse d'antenne ; la figure montre uniquement, en plan,une vue partielle de la cosse d'antenne 31 et de sa languette associée 33. On voit que la languette 33 comporte des ondulations perpendiculairement à son plan moyen comme c'était le cas pour la languette 13 ; les sommets de ces ondulations ont été désignés par 33a et les creux par 33b. Mais, en outre, on a prévu que les bordures de la languette soient également ondulées alors que ces bordures étaient rectilignes dans la réalisation des figures 1 à 4 ; la languette 33 comporte donc sur ses deux bordures longitu­dinales des protubérances 33c et des zones de creux 33d. Toutes les autres caractéristiques de ce mode de réalisa­tion sont les mêmes que celles qui ont été décrites pour la réalisation des figures 1 à 4.In Figure 5, there is shown another embodiment of the tongue, which constitutes the contact element of the antenna terminal; the figure only shows, in plan, a partial view of the antenna terminal 31 and its associated tongue 33. It can be seen that the tongue 33 has undulations perpendicular to its mean plane as was the case for the tongue 13; the vertices of these undulations were designated by 33 a and the troughs by 33 b . But, in addition, provision was made for the edges of the tongue to also be wavy while these edges were rectilinear in the embodiment of Figures 1 to 4; the tongue 33 therefore has on its two longitudinal edges protrusions 33 c and hollow areas 33 d . All the other characteristics of this embodiment are the same as those which have been described for the production of FIGS. 1 to 4.

Sur la figure 6, on a représenté un autre mode de réalisation de la cosse d'antenne ; cette figure montre une coupe selon l'axe de la cosse d'antenne, l'élément de contact de ladite cosse d'antenne n'étant pas coupé. La cosse d'antenne a été désignée par 41 dans son ensemble ; elle comporte une patte 45 sensiblement perpendiculaire à son plan ; à l'extrémité de la patte 45 est fixé un élé­ment de contact désigné par 43. L'élément de contact 43 est une tige, dont la surface extérieure présente des ondula­tions, de sorte que, sur cette surface extérieure,on trouve des zones de grand diamètre 43a et des zones de petit dia­mètre 43b. La tige 43 est fixée à l'extrémité de la patte 45 par sertissage de sa tête 44. Cette réalisation montre que l'on peut remplacer une languette plate du type de celle des figures 1 à 5 par un élément de contact de forme cylin­drique dès lors que l'élément de contact présente, en vis-à-­vis de l'âme 18 du câble coaxial, une succession de protu­bérances et de creux, les creux permettant le fluage du jonc plastique 19 et la mise en contact électrique de l'âme 18 avec l'élément de contact.In Figure 6, there is shown another embodiment of the antenna terminal; this figure shows a section along the axis of the antenna terminal, the contact element of said antenna terminal not being cut. The antenna terminal has been designated by 41 as a whole; it has a tab 45 substantially perpendicular to its plane; at the end of the lug 45 is fixed a contact element designated by 43. The contact element 43 is a rod, the external surface of which has undulations, so that, on this external surface, there are zones of large diameter 43 a and small diameter areas 43 b . The rod 43 is fixed to the end of the tab 45 by crimping its head 44. This embodiment shows that it is possible to replace a flat tongue of the type of that of FIGS. 1 to 5 with a contact element of cylindrical shape from when the contact element has, facing the core 18 of the coaxial cable, a succession of protrusions and hollows, the hollows allowing the creep of the plastic rod 19 and the electrical contacting of the core 18 with the contact element.

Sur les figures 7 et 8, on a représenté une autre variante de réalisation du dispositif selon l'invention. Dans cette variante, seule la réalisation de la cosse d'antenne est différente par rapport à celle qui a été décrite pour la variante des figures 1 à 4 ; tous les autres éléments du connecteur et du câble coaxial sont identiques et ont été désignés par les mêmes numéros de référence que pour les figures 1 à 4. La figure 7 représen­te uniquement le câble coaxial et le connecteur, abstrac­tion faite de la liaison avec l'antenne et la carrosserie du véhicule ; la figure 7 est analogue à la figure 2 en ce sens que les éléments sont représentés avant réalisation des sertissages. La cosse d'antenne est ici désignée par 51 dans son ensemble. Elle est ici supposée réalisée en une tôle très fine ; elle comporte une patte 52 sensiblement perpendiculaire à son plan moyen et l'extrémité de la patte 52 forme un élément de contact disposé en équerre par rapport à la patte 52. L'élément de contact est désigné par 53 dans son ensemble ; il est formé d'un tube obtenu par pliage ou roulage d'une zone de tôle préalablement matricée pour faire apparaître des indentations 54 qui, à l'intérieur du tube, correspondent à des protubérances faisant saillie vers l'axe du tube. L'extrémité libre de l'élément de con­tact 53 a la forme d'un biseau 53a. Le biseau 53a facilite l'introduction du tube 53 à l'intérieur de la gaine interne 17 ; au cours de cette introduction, l'âme 18 et le jonc plastique 19 viennent se loger à l'intérieur du tube 53. La cosse d'antenne 51 étant réalisée en tôle assez mince, elle est recouverte,à la base de la bague plastique 5, par une rondelle de soutien 55 permettant d'éviter sa détérioration au moment du serrage du boulon, qui vient fixer le connec­teur au droit de l'antenne. La rondelle de soutien 55 est fixée sur la bague 5 au moyen de pattes 55a.In Figures 7 and 8, there is shown another alternative embodiment of the device according to the invention. In this variant, only the embodiment of the antenna terminal is different from that which has been described for the variant of FIGS. 1 to 4; all the other elements of the connector and of the coaxial cable are identical and have been designated by the same reference numbers as for FIGS. 1 to 4. FIG. 7 represents only the coaxial cable and the connector, apart from the connection with the antenna and bodywork of the vehicle ; Figure 7 is similar to Figure 2 in that the elements are shown before crimping. The antenna terminal is here designated by 51 as a whole. It is here assumed to be made of a very thin sheet; it comprises a tab 52 substantially perpendicular to its mean plane and the end of the tab 52 forms a contact element disposed at right angles to the tab 52. The contact element is designated by 53 as a whole; it is formed of a tube obtained by folding or rolling a previously stamped sheet metal zone to reveal indentations 54 which, inside the tube, correspond to protuberances projecting towards the axis of the tube. The free end of the contact element 53 has the shape of a bevel 53 a . The bevel 53 a facilitates the introduction of the tube 53 inside the internal sheath 17; during this introduction, the core 18 and the plastic rod 19 are housed inside the tube 53. The antenna terminal 51 being made of fairly thin sheet metal, it is covered, at the base of the plastic ring 5, by a support washer 55 making it possible to avoid its deterioration when the bolt is tightened, which fixes the connector to the right of the antenna. The support washer 55 is fixed to the ring 5 by means of lugs 55 a .

Au moment où l'on effectue le sertissage des ailes 10, on provoque, dans cette variante de réalisation, l'écrasement du tube 53, de sorte que les protubérances internes du tube viennent faire contact avec l'âme 18 du câble, le jonc plastique 19 ne faisant pas obstacle à ce contact puisqu'il peut fluer dans les creux qui séparent deux protubérances adjacentes. Les autres caractéristiques et les autres avantages de cette variante sont les mêmes que ceux qui ont été décrits pour la variante des figures 1 à 4.When the wings 10 are crimped, in this variant embodiment, the tube 53 is crushed, so that the internal protuberances of the tube come into contact with the core 18 of the cable, the rod plastic 19 not obstructing this contact since it can flow in the hollows which separate two adjacent protuberances. The other characteristics and the other advantages of this variant are the same as those which have been described for the variant of FIGS. 1 to 4.

Sur la figure 9, on a représenté une vue partiel­le d'un dispositif de raccordement selon une autre variante de réalisation de l'invention ; cette vue partielle est centrée sur les ailes de sertissage 9 et 10 et ne reproduit pas l'ensemble du connecteur, dont la structure est stricte­ment identique à celle du connecteur des figures 1 à 4. La seule différence entre ce mode de réalisation et celui des figures 1 à 4 provient du fait que dans cette réalisation, les protubérances sont formées sur la gaine interne 17 et non pas sur la languette qui sert d'élément de contact et qui est raccordée à la cosse d'antenne proprement dite. Etant donné l'identité des éléments présents, on a utilisé pour ce mode de réalisation, les mêmes chiffres de référence que pour le mode de réalisation des figures 1 à 4, sauf pour la languette, qui sert d'élément de contact et qui a été dé­signée par 63 dans son ensemble. La languette 63 est une lan­guette plate qui, vue en plan selon l'axe du connecteur, a une forme sensiblement rectangulaire, sa largeur étant très légèrement inférieure au diamètre de la gaine interne 17. Comme pour la variante des figures 1 à 4, la gaine interne 17 comporte une longueur dénudée faisant saillie au-delà de l'extrémité de la gaine externe ; on met en place le câble 15 dans le manchon formé par les ailes 9 pré-roulées, la tresse 20 étant intercalée entre la gaine externe 16 et les ailes 9. Dans cette mise en place, la languette 63 vient à l'intérieur de la gaine interne 17, les positions relatives de l'âme 18, du jonc 19 et de la languette 63 étant aléatoi­res. Pour réaliser le sertissage des ailes 10, on utilise deux poinçons comportant des bossages ; de la sorte, au mo­ment où la pression de sertissage est exercée, les bossages des poinçons créent dans les ailes 10 des empreintes 90, qui génèrent sur la gaine interne 17 des protubérances 91. L'âme 18 et le jonc 19 sont pinées au sertissage entre les protubérances 91 et la languette 63 et le jonc 19 flue dans les creux entre les protubérances 91. On a donc reformé les conditions, qui existaient pour la réalisation des figures 1 à 4, conditions dont on a montré qu'elles permettaient d'obtenir de façon fiable un contact électrique entre l'âme 18, d'une part, et l'élément de contact 63 de la cosse d'antenne 11, d'autre part. Dans cette variante, on peut aussi utiliser, pour le sertissage des ailes 9, deux poin­çons comportant des bossages de façon à former dans les ailes 9 des protubérances, qui améliorent le contact élec­trique entre la cosse de masse 6 et la tresse de masse 20.In Figure 9, there is shown a partial view of a connection device according to another alternative embodiment of the invention; this partial view is centered on the crimping wings 9 and 10 and does not reproduce the entire connector, the structure of which is strictly identical to that of the connector in FIGS. 1 to 4. The only difference between this embodiment and that of FIGS. 1 to 4 stems from the fact that in this embodiment, the protuberances are formed on the internal sheath 17 and not on the tongue which serves as a contact element and which is connected to the antenna terminal proper. Given the identity of the elements present, the same reference numbers have been used for this embodiment as for the embodiment of FIGS. 1 to 4, except for the tab, which serves as a contact element and which has has been designated by 63 as a whole. The tongue 63 is a flat tongue which, seen in plan along the axis of the connector, has a substantially rectangular shape, its width being very slightly less than the diameter of the internal sheath 17. As for the variant of FIGS. 1 to 4, the inner sheath 17 has a stripped length protruding beyond the end of the outer sheath; the cable 15 is put into place in the sleeve formed by the pre-rolled wings 9, the braid 20 being interposed between the outer sheath 16 and the wings 9. In this positioning, the tongue 63 comes inside the internal sheath 17, the relative positions of the core 18, the rod 19 and the tongue 63 being random. To achieve the crimping of the wings 10, two punches are used comprising bosses; in this way, when the crimping pressure is exerted, the bosses of the punches create in the wings 10 indentations 90, which generate protrusions 91 on the internal sheath 17. The core 18 and the rod 19 are pinched during crimping between the protrusions 91 and the tongue 63 and the rod 19 flowing in the hollows between the protrusions 91. The conditions which existed for the realization of FIGS. 1 to 4 have therefore been reformed, conditions which have been shown to allow reliably obtain electrical contact between the core 18, on the one hand, and the contact element 63 of the terminal antenna 11, on the other hand. In this variant, it is also possible to use, for crimping the wings 9, two punches comprising bosses so as to form protrusions in the wings 9, which improve the electrical contact between the ground terminal 6 and the ground braid 20.

Sur les figures 10 et 11, on a représenté un dernier mode de réalisation du dispositif de raccordement selon l'invention. La figure 10 est une vue partielle du dispositif de raccordement, tout-à-fait analogue à la figure 9, c'est-à-dire que l'on a représenté la zone comprise dans les ailes de sertissage 9 et 10 et la partie adjacente du connecteur, le reste du dispositif étant strictement identique à celui qui a été décrit pour la variante des figures 1 à 4.In Figures 10 and 11, there is shown a last embodiment of the connection device according to the invention. FIG. 10 is a partial view of the connection device, entirely similar to FIG. 9, that is to say that the zone included in the crimping wings 9 and 10 and the part are shown. adjacent to the connector, the rest of the device being strictly identical to that which has been described for the variant of FIGS. 1 to 4.

Dans ce mode de réalisation, la gaine interne 17 ne comporte pas une longueur dénudée faisant saillie au-­delà de l'extrémité de la gaine externe. En d'autres termes, à partir d'un câble 15 préparé comme indiqué pour la varian­te des figures 1 à 4, on a rabattu la tresse 20 sur l'exté­rieur de la gaine externe 16 puis on a coupé la gaine inter­ne 17 de façon à ne laisser qu'une très faible longueur en saillie par rapport à la section de la gaine externe. On introduit alors dans l'extrémité libre de la gaine interne l'une des extrémités d'un manchon désigné par 70 dans son ensemble. Le manchon 70 comporte deux parties cy­lindriques 70a, 70b. La partie 70a, de plus faible diamètre, est celle qui est engagée à l'intérieur de la gaine interne 17 ; la partie 70b, de plus grand diamètre, fait saillie par rapport à l'extrémité du câble 15 lorsque la partie 70a est entièrement engagée dans la gaine interne 17. La partie 70a comporte intérieurement des bossages 71, qui font saillie en direction de l'axe de ladite partie 70a. La partie 70b est entourée d'un tronçon de gaine isolante 73 formant un four­reau isolant. Le câble ainsi équipé de son manchon est en­filé à l'intérieur des ailes 9 qui, comme dans la variante des figures 1 à 4, ont été préformées pour constituer un fourreau cylindrique. Lors de cette mise en place, la partie 70b du manchon 70 vient s'enfiler sur la patte de liaison 72 de la cosse d'antenne 11. La patte de liaison 72 peut être une languette analogue à la languette 13 ou analogue à la languette 63. Quand on procède alors au sertissage des ailes 9 et 10, la partie 70a du manchon 70 est écrasée au droit des ailes 9 et les bossages 71 viennent faire contact sur l'âme 18 du câble coaxial 15. Le sertissage des ailes 10 assure le contact entre la partie 70b et la patte 72 de la cosse d'antenne 11. On assure donc encore,par le double sertissage des ailes 9 et 10 de la cosse de masse 6, la liaison électrique entre l'âme 18 du câble coaxial et la cosse d'antenne 11 du con­ecteur. La particularité de ce mode de réalisation est que le câble coaxial peut être pré-équipé de son manchon 70 avant d'être amené en position de sertissage sur le connec­teur.In this embodiment, the inner sheath 17 does not have a stripped length protruding beyond the end of the outer sheath. In other words, from a cable 15 prepared as indicated for the variant of FIGS. 1 to 4, the braid 20 is folded over the outside of the external sheath 16 and then the internal sheath 17 is cut so to leave only a very short protruding length relative to the section of the outer sheath. One then introduces into the free end of the internal sheath one of the ends of a sleeve designated by 70 as a whole. The sleeve 70 has two cylindrical parts 70 a , 70 b . The part 70 a , of smaller diameter, is that which is engaged inside the internal sheath 17; the part 70 b , of larger diameter, protrudes relative to the end of the cable 15 when the part 70 a is fully engaged in the internal sheath 17. The part 70 a has internally bosses 71, which project in the direction the axis of said part 70 a . The portion 70 b is surrounded by an insulating sheath section 73 forming an insulating sleeve. The cable thus equipped with its sleeve is threaded inside the wings 9 which, as in the variant of FIGS. 1 to 4, have been preformed to form a cylindrical sheath. In this implementation, the portion 70 b of the sleeve 70 comes to be put on the connecting lug 72 of the antenna terminal 11. The tab 72 may be connecting a similar tongue to the tongue 13 or the like to tongue 63. When the wings 9 and 10 are then crimped, the part 70 a of the sleeve 70 is crushed in line with the wings 9 and the bosses 71 come into contact with the core 18 of the coaxial cable 15. The crimping of the wings 10 ensures contact between the part 70 b and the tab 72 of the antenna terminal 11. It is therefore also ensured, by the double crimping of the wings 9 and 10 of the ground terminal 6, the electrical connection between the core 18 of the coaxial cable and the antenna terminal 11 of the connector. The particularity of this embodiment is that the coaxial cable can be pre-equipped with its sleeve 70 before being brought into the crimp position on the connector.

Dans une variante de ce mode de réalisation, la partie 70b du manchon 70 vient s'enficher sur la patte de liaison 72 avec un léger serrage ; il n'y a plus besoin de réaliser le second sertissage sur les ailes 10 ; les ailes 10 sont laissées dans l'état représenté sur la figure 10 et forment simplement un tunnel d'anti-parasitage autour de la partie 70b. Dans ce cas, la présence du tronçon de gaine isolante 73 n'est plus nécessaire. L'extrémité du câble 15 peut être équipée de son manchon 70 puis amenée pour enfi­chage sur la patte 72, le montage se terminant par le ser­tissage sur les ailes 9.In a variant of this embodiment, the portion 70 b of the sleeve 70 is plugged on the leg link 72 with a slight interference; there is no longer any need to carry out the second crimping on the wings 10; the wings 10 are left in the state shown in FIG. 10 and simply form an anti-interference tunnel around the part 70 b . In this case, the presence of the insulating sheath section 73 is no longer necessary. The end of the cable 15 can be fitted with its sleeve 70 and then brought for plugging in on the tab 72, the assembly ending with crimping on the wings 9.

Il convient de noter que le mode de réalisation correspondant aux figures 10 et 11 est tout particulièrement utilisable pour les câbles dont l'élément-support de l'âme est un remplissage de mousse, car dans ce cas, le manchon repousse ou perfore la mousse à l'intérieur de la gaine interne au moment de son introduction et dénude, par consé­quent, l'âme 18 du câble 15 en la séparant de sa mousse-­ support au niveau des protubérances 71. Cependant, la varian­te représentée sur les figures 7 et 8, dans laquelle l'élé­ment de contact a une forme tubulaire, peut également être utilisée pour les câbles coaxiaux, dont l'élément-support de l'âme est un remplissage de mousse.It should be noted that the embodiment corresponding to FIGS. 10 and 11 is very particularly usable for cables whose support element of the core is a foam filling, because in this case, the sleeve repels or perforates the foam inside the internal sheath at the time of its introduction and therefore strips the core 18 of the cable 15 by separating it from its foam support at the level of the protrusions 71. However, the variant shown in FIGS. 7 and 8, in which the contact element has a tubular shape, can also be used for coaxial cables, including the support element of the core is a foam filling.

Dans un exemple de réalisation, le diamètre in­terne de la gaine 17 est sensiblement égal à 2,3 mm ; la largeur de la languette telle que 13, ou de la tige telle que 43, est de l'ordre de 2, 25 mm à 2,3 mm ; l'épaisseur appa­rente de la languette ou tige, correspondant à la distance entre les sommets d'ondulations opposées, est sensiblement égale à 1,1 mm ; la longueur est de l'ordre de 8,8 mm.In an exemplary embodiment, the internal diameter of the sheath 17 is substantially equal to 2.3 mm; the width of the tongue such as 13, or of the rod such as 43, is of the order of 2.25 mm to 2.3 mm; the apparent thickness of the tongue or rod, corresponding to the distance between the vertices of opposite corrugations, is substantially equal to 1.1 mm; the length is of the order of 8.8 mm.

Il est bien entendu que les modes de réalisation ci-dessus décrits ne sont aucunement limitatifs et pourront donner lieu à toutes modifications désirables, sans sortir pour cela du cadre de l'invention.It is understood that the embodiments described above are in no way limiting and may give rise to any desirable modifications, without departing from the scope of the invention.
