Description

L'invention est relative à un dispositif de raccordement de l'âme d'un câble coaxial du genre de ceux qui comportent une broche que l'on insère dans l'évidement d'un noyau, ledit évidement n'étant, plus particulièrement, pas directement accessible, l'évidement se raccordant à une région de section droite supérieure à celle de l'évidement, la zone de jonction entre ladite région et l'évidement comportant une arête vive.The invention relates to a device for connecting the core of a coaxial cable of the type which includes a pin which is inserted into the recess of a core, said recess not being, more particularly, not directly accessible, the recess connecting to a region of cross section greater than that of the recess, the junction zone between said region and the recess comprising a sharp edge.

Un tel dispositif peut, notamment, être utilisé pour le raccordement d'un antenne à un poste autoradio, et faire partie d'un ensemble de connexion du câble.Such a device can, in particular, be used for the connection of an antenna to a car radio, and be part of a cable connection assembly.

De façon connue, les ensembles de connexion pour câble coaxial comportent une pièce métallique destinée à être reliée électriquement à la tresse métallique du câble coaxial, cette pièce comportant généralement, d'une part, un appendice tubulaire destiné à recevoir l'extrémité du câble coaxial et un dispositif de raccordement de l'âme du câble comportant une broche métallique que l'on insère dans l'évidement d'un noyau. La broche serre l'âme du câble contre la paroi de l'évidement.In known manner, the connection assemblies for coaxial cable comprise a metal part intended to be electrically connected to the metal braid of the coaxial cable, this part generally comprising, on the one hand, a tubular appendage intended to receive the end of the coaxial cable and a device for connecting the cable core comprising a metal pin which is inserted into the recess of a core. The pin clamps the cable core against the wall of the recess.

Les broches généralement utilisées sont des pièces métalliques allongées de section droite circulaire ou polygonale et dont les extrémités peuvent être arrondies, coniques ou pyramidales. La section transversale de l'évidement a une forme et des dimensions correspondant à la forme de la broche.The pins generally used are elongated metal parts of circular or polygonal cross section and the ends of which can be rounded, conical or pyramidal. The cross section of the recess has a shape and dimensions corresponding to the shape of the pin.

La connexion de l'âme du câble et de la broche pose un problème particulier car l'âme est constituée par un fil fin, dont le diamètre peut être de l'ordre de 0,3 mm, notamment lorsqu'il s'agit d'une âme flottant à l'intérieur d'une gaine dite "gaine d'air", sans être fixée dedans. Lorsqu'on enfonce la broche dans le susdit évidement, l'âme a tendance à s'échapper et à rentrer dans la gaine de sorte que le raccordement ne se trouve pas effectué ou est réalisé dans de mauvaises conditions.The connection of the cable core and the pin poses a particular problem because the core consists of a thin wire, the diameter of which can be of the order of 0.3 mm, in particular when it is a question of 'a floating soul inside a sheath called "sheath air ", without being fixed therein. When the spindle is inserted into the above-mentioned recess, the core tends to escape and re-enter the sheath so that the connection is not made or is made in bad conditions.

Lorsque l'ouverture de l'évidement par laquelle on introduit la broche est assez facilement accessible, il est possible de faire sortir l'âme de plusieurs millimètres à l'extérieur de l'évidement, puis de la pousser transversalement à l'aide d'un outil, à l'extérieur de l'évidement pour qu'elle se plie et se couche sur le bord de l'évidement. On coupe ensuite l'excès de fil puis on introduit la broche dans l'évidement, l'âme étant généralement suffisamment retenue à la suite des opérations décrites précédemment, pour ne pas reculer lors de cette introduction.When the opening of the recess through which the spindle is introduced is fairly easily accessible, it is possible to bring the core out by several millimeters outside the recess, then to push it transversely using 'a tool, outside the recess so that it folds and lies down on the edge of the recess. The excess wire is then cut and the spindle is introduced into the recess, the core being generally sufficiently retained following the operations described above, so as not to retreat during this introduction.

Il est clair cependant que de telles opérations sont relativement délicates, prennent du temps et ne permettent pas une automatisation poussée du montage du dispositif de raccordement.It is clear, however, that such operations are relatively delicate, take time and do not allow extensive automation of the mounting of the connection device.

Les difficultés de réalisation du raccordement sont accrues lorsque l'évidement n'est pas directement accessible mais se trouve au fond d'un manchon relativement long prévu, notamment, pour réduire les risques de mise en court-circuit. Dans un tel cas, il n'est pratiquement plus possible d'agir transversalement sur le fil constituant l'âme, au fond du manchon, à l'entrée de l'évidement, pour éviter que l'âme ne soit repoussée lorsqu'on enfonce la broche dans l'évidement. Dans ces conditions, on est amené à effectuer le raccordement de l'âme sur la broche par soudure, ce qui complique les opérations.The difficulties in making the connection are increased when the recess is not directly accessible but is located at the bottom of a relatively long sleeve provided, in particular, to reduce the risks of short-circuiting. In such a case, it is practically no longer possible to act transversely on the wire constituting the core, at the bottom of the sleeve, at the entrance to the recess, to prevent the core from being pushed back when press the spindle into the recess. Under these conditions, it is necessary to carry out the connection of the core to the spindle by welding, which complicates the operations.

On connaît, par ailleurs, d'après FR-A-1 495 934, un dispositif de raccordement pour câble électrique comprenant une bague métallique avec une arête vive, bague qui peut être vissée sur une broche filetée biseautée à son extrémité. Le câble conducteur, entouré de sa gaine isolante, est engagé dans la bague métallique et, lors du vissage de cette bague sur la broche, l'arête coupe la gaine du câble isolant et établit une liaison conductrice avec le câble métallique.Furthermore, from FR-A-1 495 934, a connection device for an electric cable is known, comprising a metal ring with an edge. lively, ring which can be screwed onto a threaded pin bevelled at its end. The conductive cable, surrounded by its insulating sheath, is engaged in the metal ring and, when this ring is screwed onto the spindle, the edge cuts the sheath of the insulating cable and establishes a conductive connection with the metal cable.

Il est clair qu'un tel dispositif est susceptible de blesser le conducteur métallique car, lors du vissage de la bague sur la broche, pour couper la gaine isolante, il est difficile de déterminer à quel moment précis l'arête vive de la bague métallique entre en contact avec le conducteur métallique. Ceci n'est pas véritablement gênant pour un câble dont le conducteur métallique a un diamètre relativement important.It is clear that such a device is capable of injuring the metal conductor because, when screwing the ring on the pin, to cut the insulating sheath, it is difficult to determine at what precise moment the sharp edge of the metal ring comes into contact with the metallic conductor. This is not really annoying for a cable whose metallic conductor has a relatively large diameter.

Ce n'est pas le cas pour l'âme d'un câble coaxial.This is not the case for the core of a coaxial cable.

L'invention a pour but, surtout, de fournir un dispositif de raccordement du genre défini précédemment qui permette de raccorder sans soudure à une broche, de façon fiable, l'âme d'un câble coaxial, alors même que l'évidement du noyau n'est pas directement accessible, en étant situé au fond d'un logement.The object of the invention is, above all, to provide a connection device of the kind defined above which makes it possible to connect seamlessly to a pin, in a reliable manner, the core of a coaxial cable, even though the recess of the core is not directly accessible, being located at the bottom of a dwelling.

L'invention a également pour but de fournir un tel dispositif de raccordement dont les opérations de montage peuvent être rendues aisément automatiques, pour des productions en grande série, tout en assurant une grande fiabilité du raccordement effectué entre la broche et l'âme du câble coaxial.The invention also aims to provide such a connection device whose mounting operations can be made easily automatic, for mass production, while ensuring high reliability of the connection made between the pin and the cable core coaxial.

Selon l'invention, un dispositif de raccordement du genre défini précédemment, est caractérisé par le fait qu'il est agencé pour permettre d'engager la broche dans l'évidement par un mouvement de translation, après insertion de l'âme dénudée dans ledit évidement de sorte que l'âme soit coincée dans l'évidement ; que le noyau est isolant, en matière plastique de dureté appropriée ; que la susdite région de section droite supérieure à celle de l'évidement est constituée par un avant-trou prévu dans le noyau et coaxial à l'évidement ; que l'arête vive est formée par le sommet d'une lèvre prévue dans le noyau à la jonction de l'évidement et de l'avant-trou, la lèvre présentant des faces formant un angle ; l'ensemble étant tel que, lors de la mise en place de la broche dans l'évidement, l'âme du conducteur s'incruste dans l'arête vive par déformation de la matière plastique du noyau, l'âme étant ainsi freinée, sans risque d'être abîmée, par ladite arête vive déformée.According to the invention, a connection device of the kind defined above, is characterized in that it is arranged to allow the spindle to be engaged in the recess by a translational movement, after insertion of the stripped core into said recess so that the soul is stuck in the recess; that the core is insulating, made of plastic of appropriate hardness; that the aforesaid cross-sectional region greater than that of the recess is constituted by a pilot hole provided in the core and coaxial with the recess; that the sharp edge is formed by the top of a lip provided in the core at the junction of the recess and the pilot hole, the lip having faces forming an angle; the assembly being such that, during the positioning of the spindle in the recess, the core of the conductor becomes embedded in the sharp edge by deformation of the plastic material of the core, the core being thus braked, without risk of being damaged, by said sharp deformed edge.

L'avant-trou peut avoir une longueur axiale supérieure à celle de l'évidement.The pilot hole may have an axial length greater than that of the recess.

De préférence, la broche présente une surface lisse suivant la direction longitudinale correspondant à la direction d'introduction par translation de la broche dans l'évidement. Le risque d'accrocher et de repousser l'âme lors de l'introduction est ainsi réduit.Preferably, the spindle has a smooth surface in the longitudinal direction corresponding to the direction of introduction by translation of the spindle into the recess. The risk of catching and repelling the core during the introduction is thus reduced.

Généralement la broche présente des extrémités coniques. L'angle au sommet de ces extrémités coniques est de préférence compris entre 30° et 45°.Generally the pin has tapered ends. The angle at the top of these conical ends is preferably between 30 ° and 45 °.

L'arête de l'évidement peut être constituée par le bord d'un épaulement perpendiculaire à l'axe commun de l'évidement et de l'avant-trou reliant la paroi de l'évidement à l'avant-trou, les faces de la lèvre étant constituées par ledit épaulement et par la zone voisine de la paroi de l'évidement et faisant entre elles, en section dans un plan axial, un angle de 90°.The edge of the recess may consist of the edge of a shoulder perpendicular to the common axis of the recess and of the pilot hole connecting the wall of the recess to the pilot hole, the faces of the lip being formed by said shoulder and by the area adjacent to the wall of the recess and forming between them, in section in an axial plane, an angle of 90 °.

Selon une autre possibilité, la lèvre est constituée par une saillie formant un angle aigu et dirigée vers l'axe commun de l'évidement et de l'avant-trou, l'arête vive formant le sommet de la saillie. Dans ce cas, les faces de la lèvre peuvent être formées par un épaulement perpendiculaire à l'axe commun et par une paroi tronconique reliant le bord dudit épaulement et la paroi de l'évidement.According to another possibility, the lip is constituted by a projection forming an acute angle and directed towards the common axis of the recess and the pilot hole, the sharp edge forming the top of the projection. In this case, the faces of the lip can be formed by a shoulder perpendicular to the common axis and by a frustoconical wall connecting the edge of said shoulder and the wall of the recess.

Selon une autre possibilité, la lèvre est constituée par une saillie formant un angle aigu dirigée dans l'avant-trou parallèlement à l'axe commun de l'évidement et de l'avant-trou. Dans ce cas, les faces de la lèvre peuvent être formées par un prolongement dans l'avant-trou de la paroi de l'évidement et par une paroi tronconique reliant le bord dudit prolongement à un épaulement perpendiculaire à l'axe commun.According to another possibility, the lip is constituted by a projection forming an acute angle directed into the pilot hole parallel to the common axis of the recess and the pilot hole. In this case, the faces of the lip can be formed by an extension in the pilot hole of the wall of the recess and by a frustoconical wall connecting the edge of said extension to a shoulder perpendicular to the common axis.

Dans un dispositif conforme à l'invention, l'âme du câble coaxial est appliquée contre l'arête vive du noyau en matière plastique, de dureté appropriée, de manière à s'y incruster ; l'âme est ainsi freinée par l'arête et reste en place lors de l'introduction de la broche, qui ne comporte aucune aspérité susceptible d'accrocher l'âme et de la repousser.In a device according to the invention, the core of the coaxial cable is applied against the sharp edge of the plastic core, of suitable hardness, so as to become embedded therein; the core is thus braked by the edge and remains in place during the introduction of the spindle, which has no roughness capable of catching the core and repelling it.

Au cours du processus de raccordement, on utilise une longueur d'âme telle que son extrémité reste dans l'avant-trou, mais soit suffisante pour que l'âme lors de l'enfoncement de la broche, puisse s'incliner dans l'avant-trou. Cette longueur importante de l'âme dépassant l'évidement n'est pas gênante dans le cas où le noyau est contenu dans un manchon métallique qui est à la masse car, du fait de la longueur importante de l'avant-trou, l'âme ne peut pas entrer en contact avec le manchon. On évite ainsi les risques de formation d'un court-circuit vers la masse ou toute autre anomalie électrique due au fait que la distance entre l'âme et la masse ne serait pas constante.During the connection process, a core length is used such that its end remains in the pilot hole, but is sufficient so that the core when the pin is driven in, can tilt in the pilot hole. This significant length of the core exceeding the recess is not a problem in the case where the core is contained in a metal sleeve which is grounded because, due to the significant length of the pilot hole, the soul cannot come into contact with the sleeve. This avoids the risks of a short-circuit to ground or any other electrical anomaly due to the fact that the distance between the core and the ground would not be constant.

L'invention consiste, mises à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions dont il sera plus explicitement question ci-après à propos d'un exemple de réalisation décrit avec référence au dessin ci-annexé, mais qui n'est nullement limitatif.The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be more explicitly discussed below in connection with an exemplary embodiment described with reference to the attached drawing, but which is by no means limiting.

La figure 1, de ce dessin, est une vue schématique en coupe axiale d'un premier mode de réalisation du dispositif selon l'invention.Figure 1 of this drawing is a schematic view in axial section of a first embodiment of the device according to the invention.

Les figures 2 et 3, enfin, sont des vues schématiques en coupe axiale montrant deux modes de réalisation différents des lèvres formant les arêtes vives selon l'invention.Figures 2 and 3, finally, are schematic views in axial section showing two different embodiments of the lips forming the sharp edges according to the invention.

Le dispositif de raccordement de l'âme 11 d'un câble coaxial 1 représenté sur la figure 1 comporte une broche métallique 2 et un noyau isolant 3 en matière plastique dans lequel sont ménagés un évidement 4 et un avant-trou 5.The device for connecting the core 11 of a coaxial cable 1 shown in FIG. 1 comprises a metal pin 2 and an insulating core 3 made of plastic material in which are formed a recess 4 and a pilot hole 5.

Le câble coaxial 1 est constitué d'une âme 11, dont une extrémité est dénudée, âme 11 entourée d'une gaine isolante 12 concentrique, puis d'une tresse métallique 13 et d'une couche isolante extérieure 14. La gaine isolante 12 est une gaine d'air, c'est-à-dire que l'âme 11 flotte à l'intérieur de la gaine isolante 12 qui contient de l'air. L'âme 11 est maintenue dans la gaine d'air par un jonc plastique (non représenté) disposé en hélice à pas très large.The coaxial cable 1 consists of a core 11, one end of which is exposed, core 11 surrounded by a concentric insulating sheath 12, then a metal braid 13 and an outer insulating layer 14. The insulating sheath 12 is an air sheath, that is to say that the core 11 floats inside the insulating sheath 12 which contains air. The core 11 is held in the air duct by a plastic rod (not shown) arranged in a helix with a very wide pitch.

Le noyau 3 est isolant, en matière plastique de dureté appropriée.The core 3 is insulating, made of plastic of appropriate hardness.

Le noyau isolant 3 a, selon le mode de réalisation représenté, une forme cylindrique de section circulaire et il est traversé par l'évidement axial 4, cylindrique à section circulaire, qui est relié du côté d'introduction du câble 1 à une ouverture tronconique 6 et côté introduction de la broche 2 à l'avant-trou 5 qui, selon le mode de réalisation représenté est cylindrique à section circulaire.The insulating core 3 has, according to the embodiment shown, a cylindrical shape of circular section and it is crossed by the axial recess 4, cylindrical with circular section, which is connected on the insertion side of the cable 1 to a tapered opening 6 and insertion side of the pin 2 to the pilot hole 5 which, according to the embodiment shown, is cylindrical with circular section.

La longueur axiale L de l'avant-trou 5 est supérieure à la longueur axiale h de l'évidement 4.The axial length L of the pilot hole 5 is greater than the axial length h of the recess 4.

L'avant-trou 5, l'évidement 4 et l'ouverture tronconique 6 ont un axe commun X-X. La jonction entre l'avant-trou 5 et l'évidement 4 se fait par un épaulement annulaire 7, dont le plan est perpendiculaire à l'axe commun X-X.The pilot hole 5, the recess 4 and the frustoconical opening 6 have a common axis X-X. The junction between the pilot hole 5 and the recess 4 is made by an annular shoulder 7, the plane of which is perpendicular to the common axis X-X.

Une lèvre annulaire 8 est formée, dans le noyau 3, à la jonction de l'évidement 4 et de l'avant-trou 5. Cette lèvre 8 présente des faces constituées par l'épaulement 7 et la zone voisine de la paroi intérieure de l'évidement 4. Ces faces forment entre elles un angle égal à 90° dans le cas de la figure 1.An annular lip 8 is formed, in the core 3, at the junction of the recess 4 and the pilot hole 5. This lip 8 has faces formed by the shoulder 7 and the area adjacent to the inner wall of the recess 4. These faces form between them an angle equal to 90 ° in the case of FIG. 1.

Une arête vive 9 est formée par le sommet de cette lèvre 8.A sharp edge 9 is formed by the top of this lip 8.

La broche 2 est constituée par un cylindre métallique 21 muni à chacune de ses extrémités d'une partie conique 22, la jonction entre la partie cylindrique 21 et la partie conique 22 s'effectuant à l'aide d'une surface arrondie 23.The pin 2 consists of a metal cylinder 21 provided at each of its ends with a conical part 22, the junction between the cylindrical part 21 and the conical part 22 being effected by means of a rounded surface 23.

La broche 2 présente une surface lisse suivant la direction longitudinale parallèle à l'axe X-X, correspondant à la direction d'introduction par translation de la broche dans l'évidement 4. De cette façon la broche ne présente aucune aspérité ou aucun angle vif. L'angle au sommet de la partie conique est avantageusement de 30° à 45°.The spindle 2 has a smooth surface in the longitudinal direction parallel to the axis X-X, corresponding to the direction of introduction by translation of the spindle into the recess 4. In this way the spindle has no roughness or any sharp angle. The angle at the top of the conical part is advantageously from 30 ° to 45 °.

Le dispositif de raccordement fonctionne de la façon décrite ci-après.The connection device operates as described below.

La partie dénudée de l'âme 11 du câble 1 est introduite par l'ouverture tronconique 6 dans l'évidement 4 puis l'avant-trou 5 jusqu'à ce que son extrémité dépasse légèrement l'ouverture d'entrée de l'avant-trou 5. La broche 2 est alors introduite par une extrémité conique 22 dans l'avant-trou cylindrique 5. La broche en s'enfonçant dans l'avant-trou 5 repousse latéralement l'âme 11 en l'inclinant vers la paroi latérale de l'avant-trou 5 et lorsque la partie cylindrique 21 de la broche 2 arrive au niveau de l'épaulement 7, elle applique l'âme 11 contre l'arête vive 9 et l'incruste dans ladite arête. Lorsque l'on continue à enfoncer la broche 2, elle ne risque plus d'entraîner l'âme 11 freinée par l'arête 9, et la partie cylindrique 21 de la broche vient coincer l'âme 11 contre la paroi interne de l'évidement 4. L'âme 11 est ainsi maintenue en place et le contact électrique entre l'âme 11 et la broche 2 est établi.The stripped part of the core 11 of the cable 1 is introduced through the frustoconical opening 6 into the recess 4 then the pilot hole 5 until its end slightly exceeds the entry opening of the pilot hole 5. The pin 2 is then introduced by a conical end 22 into the pilot cylindrical hole 5. The pin by sinking into the pilot hole 5 laterally pushes the core 11 by tilting it towards the side wall of the pilot hole 5 and when the cylindrical part 21 of the pin 2 reaches the level of the shoulder 7, it applies the core 11 against the sharp edge 9 and encrusts it in said edge. When one continues to drive in the spindle 2, it no longer risks entraining the core 11 braked by the edge 9, and the cylindrical part 21 of the spindle comes to wedge the core 11 against the internal wall of the recess 4. The core 11 is thus held in place and the electrical contact between the core 11 and the pin 2 is established.

Le dispositif de raccordement est ainsi agencé pour permettre d'engager et de coincer la broche 2 dans l'évidement par un mouvement de translation, après insertion de l'âme dénudée dans ledit évidement 4.The connection device is thus arranged to allow the pin 2 to be engaged and wedged in the recess by a translational movement, after insertion of the stripped core into said recess 4.

Les opérations décrites précédemment pour réaliser le raccordement peuvent être aisément automatisées et assurer une grande fiabilité dans le raccordement électrique réalisé entre l'âme du conducteur coaxial et la broche 2.The operations described above for making the connection can be easily automated and ensure high reliability in the electrical connection made between the core of the coaxial conductor and the pin 2.

Dans l'exemple considéré, les extrémités de la broche 2 sont coniques de manière à assurer, au début de son introduction, l'incrustation de l'âme 11 dans la lèvre 9 du noyau 3 et le freinage de cette âme par ledit noyau, dont la matière plastique est choisie avec une dureté appropriée pour permettre cette incrustation sans blesser l'âme 11, et pour assurer un bon freinage.In the example considered, the ends of the spindle 2 are conical so as to ensure, at the start of its introduction, the inlay of the core 11 in the lip 9 of the core 3 and the braking of this core by said core, whose plastic material is chosen with an appropriate hardness to allow this encrustation without injuring the core 11, and to ensure good braking.

On pourrait toutefois, dans une première étape, à l'aide d'un outil à extrémité conique, réaliser ces opérations d'incrustation et de freinage dans l'âme 11, l'outil serait ensuite retiré de l'évidement 4 alors que l'âme 11 resterait en place, incrustée dans la lèvre 9. Dans une étape suivante, une broche à extrémité cylindrique légèrement arrondie, pourrait être introduite directement dans l'évidement 4, sans risque de repousser l'âme 11 suffisamment freinée.However, in a first step, using a tool with a conical end, perform these incrustation and braking operations in the core 11, the tool would then be removed from the recess 4 while the core 11 would remain in place, embedded in the lip 9. In a following step, a spindle to slightly rounded cylindrical end, could be introduced directly into the recess 4, without risk of pushing the core 11 sufficiently braked.

La figure 2 représente un mode de réalisation d'un noyau isolant 103 dans lequel la lèvre 108 forme un angle aigu et fait saillie en direction de l'axe du noyau isolant. Le noyau isolant 103 est percé d'une ouverture tronconique 106, d'un évidement 104 et d'un avant-trou 105 ayant un axe commun X-X. La lèvre 108 est circulaire et ses faces sont constituées par un épaulement annulaire 107 perpendiculaire à l'axe commun X-X et par une paroi tronconique 110 reliant le bord de l'épaulement 107 à la paroi interne de l'évidement 104. L'angle formé entre 107 et 110, en section par un plan longitudinal, est un angle aigu. L'arête vive 109 est constituée par le cercle commun à l'épaulement 107 et à la paroi tronconique 110. La lèvre 108 a une certaine élasticité, ce qui lui permet de s'effacer lors de l'introduction de la broche et elle a l'avantage de faciliter l'incrustation de l'âme du câble dans l'arête vive 109.FIG. 2 represents an embodiment of an insulating core 103 in which the lip 108 forms an acute angle and projects in the direction of the axis of the insulating core. The insulating core 103 is pierced with a frustoconical opening 106, a recess 104 and a pilot hole 105 having a common axis X-X. The lip 108 is circular and its faces are formed by an annular shoulder 107 perpendicular to the common axis XX and by a frustoconical wall 110 connecting the edge of the shoulder 107 to the internal wall of the recess 104. The angle formed between 107 and 110, in section through a longitudinal plane, is an acute angle. The sharp edge 109 is constituted by the circle common to the shoulder 107 and to the frustoconical wall 110. The lip 108 has a certain elasticity, which allows it to be erased during the introduction of the spindle and it has the advantage of facilitating the encrustation of the cable core in the sharp edge 109.

La figure 3 représente un autre mode de réalisation d'un noyau isolant 203 dans lequel la lèvre 208 forme un angle aigu et fait saillie dans l'avant-trou 205 parallèlement à l'axe X-X d'un noyau isolant 203. Le noyau isolant 203 est percé, dans l'ordre, d'une ouverture tronconique 206 pour l'introduction du câble, d'un évidement 204 dans lequel la broche coince l'âme du câble et d'un avant-trou 205. L'ouverture 206, l'évidement 204 et l'avant-trou 205 ont un axe commun X-X. La lèvre 208 est circulaire et ses faces sont constituées par la paroi intérieure de l'évidement 204 et par une paroi tronconique 210 reliant la paroi intérieure de l'évidement 204 à un épaulement 207 perpendiculaire à l'axe commun X-X ; en section dans un plan longitudinal axial, l'angle entre la paroi intérieure de l'évidement 204 et la paroi oblique 210 est un angle aigu. L'arête vive 209 est constituée par le cercle commun à la paroi intérieure de l'évidement 204 et à la paroi oblique 210.FIG. 3 shows another embodiment of an insulating core 203 in which the lip 208 forms an acute angle and projects into the pilot hole 205 parallel to the axis XX of an insulating core 203. The insulating core 203 is pierced, in order, with a frustoconical opening 206 for the introduction of the cable, with a recess 204 in which the pin jams the core of the cable and with a pilot hole 205. The opening 206 , recess 204 and the pilot hole 205 have a common axis XX. The lip 208 is circular and its faces are formed by the inner wall of the recess 204 and by a frustoconical wall 210 connecting the inner wall of the recess 204 to a shoulder 207 perpendicular to the common axis XX; in section in an axial longitudinal plane, the angle between the interior wall of the recess 204 and the oblique wall 210 is an acute angle. The sharp edge 209 is formed by the circle common to the interior wall of the recess 204 and to the oblique wall 210.

Il est à noter que la lèvre 8, 108, 208 peut ne pas être continue sur un cercle, mais comporter des échancrures.It should be noted that the lip 8, 108, 208 may not be continuous on a circle, but have indentations.
