Abstract

The connector includes an insulating body which houses an electrical contact (1) placed inside a slit receiving the extremity of a cable. The contact includes two blades (10,11) parallel with a vertical axis and separated by a longitudinal slit (13). The dimension of the slit is determined by the diameter of the cable to be connected. The upper sides of the blades are separated at an angle (alpha) thus defining a V. The cable (3) to be connected is inserted in the connector slit (21) between the blades and forced inside. As a result of the pushing effort the first blade (10) cuts the cable insulation thus making contact with the cable conducting core.

Description

L'invention concerne dispositif à contacts électriques à déplacement d'isolant.The invention relates to an electrical contact device with insulation displacement.

Dans l'art connu, il a été proposé de nombreux éléments de contact électrique à déplacement d'isolant du type précité. Ces éléments de contact à déplacement d'isolant sont supportés par le corps isolant d'un bornier ou d'un organe similaire. Celui-ci est muni un orifice ou une fente d'introduction. Le contact électrique lui-même comporte une ou plusieurs lames qui tranchent l'isolant d'un fil ou câble électrique lorsque celui-ci est introduit dans l'orifice ou la fente, et mord dans l'âme conductrice de celui-ci. De ce fait, il s'établit un contact galvanique entre l'âme conductrice et le contact à déplacement d'isolant. Ce dernier est en général prolongé par un organe de prise de contact électrique (organe de raccordement ou broche) sur lequel on peut insérer un organe complémentaire formant l'extrémité d'un câble électrique ou, au contraire, que l'on peut insérer dans un trou métallisé d'une plaque de circuit imprimé.In the prior art, numerous electrical contact elements with insulation displacement of the aforementioned type have been proposed. These insulation displacement contact elements are supported by the insulating body of a terminal block or the like. This is provided with an orifice or an insertion slot. The electrical contact itself comprises one or more blades which cut through the insulation of an electric wire or cable when the latter is introduced into the orifice or the slot, and bites into the conductive core thereof. Therefore, a galvanic contact is established between the conductive core and the insulation displacement contact. The latter is generally extended by an electrical contacting member (connection member or pin) on which one can insert a complementary member forming the end of an electrical cable or, on the contrary, which one can insert into a metallized hole in a printed circuit board.

Dans une configuration classique, les contacts à déplacement d'isolant comprennent une lyre ou un "V", dont les branches élastiques jouent le rôle de lames, dont le tranchant est tourné vers l'intérieur. Ces lames sont parallèles et comprises dans un même plan. Elles sont séparées par une fente dont la dimension est adaptée aux dimensions des fils ou câbles devant être introduits dans le contact autodénudant. L'introduction d'un câble entre les deux lames déclenche le processus : du fait de leur élasticité, les lames coupent la gaine isolante tout en assurant la rétention du câble.In a conventional configuration, the insulation displacement contacts comprise a lyre or a "V", the elastic branches of which act as blades, the cutting edge of which is turned inward. These blades are parallel and included in the same plane. They are separated by a slot, the size of which is adapted to the dimensions of the wires or cables to be introduced into the insulation displacement contact. The introduction of a cable between the two blades triggers the process: due to their elasticity, the blades cut the insulating sheath while ensuring the retention of the cable.

Dans la demande de brevet PCT WO-A-92/22941 (MOD-TAP W. CORPORATION), il a été proposé un contact à déplacement d'isolant amélioré, dont les lames travaillent en torsion.In PCT patent application WO-A-92/22941 (MOD-TAP W. CORPORATION), an improved insulation displacement contact has been proposed, the blades of which work in torsion.

Pour obtenir cet effet, deux dispositions ont été retenues :

  • les lames présentent un décalage angulaire par rapport à l'axe d'introduction du câble dans la fente ;
  • les lames sont disposées en appui sur les parois extrêmes de l'isolant à l'aide de bossages situés en partie haute des lames.
To achieve this effect, two provisions have been adopted:
  • the blades have an angular offset relative to the axis of introduction of the cable into the slot;
  • the blades are arranged in abutment on the extreme walls of the insulation using bosses located in the upper part of the blades.

Les lames sont alors maintenues en pincement dans leur partie haute. Lorsque un ou plusieurs plusieurs câbles sont introduits dans la fente, il en résulte une déformation en arc de cercle, ce qui garantit un bon fonctionnement du dispositif.The blades are then kept pinched in their upper part. When one or more cables are inserted into the slot, this results deformation in an arc, which guarantees proper operation of the device.

Bien que présentant des avantages certains sur les techniques antérieurement connues, ce dispositif ne permet pas de remplir tous les besoins qui se font sentir dans le domaine, notamment celui de pouvoir garantir une efficacité constante pour des câbles de diamètres différents.Although having certain advantages over the previously known techniques, this device does not make it possible to fulfill all the needs which are felt in the field, in particular that of being able to guarantee constant efficiency for cables of different diameters.

Tout en conservant les avantages des dispositifs de l'art connu, notamment un fonctionnement élastique des lames en "V", l'invention propose un dispositif à contact électrique à déplacement d'isolant permettant d'en différencier le fonctionnement compte-tenu de caractéristiques physiques du câble introduit, notamment de son diamètre.While retaining the advantages of the devices of the known art, in particular an elastic operation of the "V" blades, the invention proposes an electrical contact device with insulation displacement making it possible to differentiate the operation thereof taking account of characteristics physical characteristics of the cable introduced, particularly its diameter.

Pour ce faire, l'invention propose d'utiliser un élément de contact électrique à déplacement d'isolant comportant deux lames de sections distinctes, formant entre elles un angle déterminé. La lame de plus petite section est disposée dans un plan orthogonal à l'axe d'introduction du câble et la lame de section plus importante est disposée dans un plan formant un angle égal à l'angle déterminé avec ce même axe. De ce fait, et du fait de dispositions complémentaires qui seront détaillées ci-après, il est possible d'obtenir le fonctionnement différencié précité.To do this, the invention proposes to use an electrical contact element with insulation displacement comprising two blades of distinct sections, forming between them a determined angle. The blade of smaller section is arranged in a plane orthogonal to the axis of introduction of the cable and the blade of larger section is arranged in a plane forming an angle equal to the angle determined with this same axis. Therefore, and because of additional provisions which will be detailed below, it is possible to obtain the aforementioned differentiated operation.

L'invention a donc pour objet un dispositif comprenant au moins un élément de contact électrique à déplacement d'isolant disposé dans une fente réalisée dans un corps isolant et destinée à recevoir un câble muni d'une gaine isolante, suivant un axe d'insertion, ledit élément de contact à déplacement d'isolant comprenant une première et une seconde lames, réunies par une base commune et séparées par une fente de largeur déterminée dans laquelle est inséré ledit câble, caractérisé en ce que les deux lames ont des largeurs différentes, en ce que ladite fente réalisée dans le corps isolant comporte des première et seconde rainures sur des parois latérales en vis à vis, en ce que la première rainure s'étend suivant un axe ortogonal audit axe d'insertion, en ce que la seconde rainure s'étend suivant un axe formant un angle déterminé avec ledit axe d'insertion supérieur à zéro et inférieur à 90°, en ce que la lame de largeur la plus faible ou première lame est insérée dans la première rainure et la lame de largeur la plus importante ou seconde lame est insérée dans la seconde rainure de façon à ce qu'elles forment entre-elles un angle égal audit angle déterminé, en ce que ladite seconde lame est repoussée en flexion vers l'une des paroi latérale de la seconde rainure lorsqu'un câble est inséré entre les deux lames, et en ce que les bords d'attaque desdites première et seconde lames coopèrent pour exercer un effet de coin sur ledit câble et décaler les points de coupe de ladite gaine isolante, de manière à réaliser ledit déplacement d'isolant.The invention therefore relates to a device comprising at least one electrical contact element with displacement of insulation placed in a slot made in an insulating body and intended to receive a cable provided with an insulating sheath, along an insertion axis. , said insulating displacement contact element comprising first and second blades, joined by a common base and separated by a slot of determined width into which said cable is inserted, characterized in that the two blades have different widths, in that said slot made in the insulating body has first and second grooves on opposite side walls, in that the first groove extends along an axis orthogonal to said insertion axis, in that the second groove extends along an axis forming a determined angle with said insertion axis greater than zero and less than 90 °, in that the blade of the smallest or first width re blade is inserted in the first groove and the largest width blade or second blade is inserted in the second groove so that they form between them an angle equal to said determined angle, in that said second blade is pushed back in bending towards one of the side wall of the second groove when a cable is inserted between the two blades, and in that the leading edges of said first and second blades cooperate to exert a wedge effect on said cable and offset the cutting points of said insulating sheath, so as to produce said displacement of insulation.

L'invention sera mieux comprise et d'autres caractéristiques et avantages apparaîtront à la lecture de la description qui suit en référence aux figures annexées, et parmi lesquelles :

  • La figure 1 représente un exemple de découpe d'un élément de contact électrique à déplacement d'isolant selon l'invention ;

The invention will be better understood and other characteristics and advantages will appear on reading the description which follows with reference to the appended figures, and among which:
  • FIG. 1 shows an example of cutting an electrical contact element with insulation displacement according to the invention;
  • Figures 2 and 3 illustrate a terminal block comprising such contact elements, respectively in side view and from above;

  • Figures 5 and 6 illustrate the operation of the terminal block with electrical contact elements with insulation displacement, respectively when introducing a cable of a first diameter and when introducing a cable of a second diameter , higher than the first.

Selon une caractéristique essentielle de l'invention, l'élément de contact à déplacement d'isolant comporte deux lames asymétriques.According to an essential characteristic of the invention, the contact element with displacement of insulator comprises two asymmetrical blades.

La figure 1 illustre un exemple d'un tel élément de contact à déplacement d'isolant 1. Il comprend un corps principal allongé, constitué de deux ailes, 10 et 11, et s'étendant parallèlement à un axe vertical (sur la figure 1) Δ. Les deux ailes, 10 et 11, réunies par une base commune, sont séparées par une mince fente longitudinale 13, de largeur "e". Cette largeur "e" est déterminée est fonction de l'application précise envisagée, notamment du diamètre des câbles pouvant y être insérés. Dans la partie supérieure, les deux ailes, 10 et 11, sont évasées de manière à former un "V" dont les branches forment un angle α avec l'axe Δ précité. Cette disposition, connue en soi, permet un guidage plus aisé d'un câble (non représenté), en vue de son insertion dans la fente 13.Figure 1 illustrates an example of such an insulating displacement contact element 1. It comprises an elongated main body, consisting of two wings, 10 and 11, and extending parallel to a vertical axis (in Figure 1 ) Δ. The two wings, 10 and 11, joined by a common base, are separated by a thin longitudinal slot 13, of width "e". This width "e" is determined depending on the precise application envisaged, in particular the diameter of the cables that can be inserted therein. In the upper part, the two wings, 10 and 11, are flared so as to form a "V" whose branches form an angle α with the aforementioned axis Δ. This arrangement, known per se, allows easier guidance of a cable (not shown), with a view to its insertion into the slot 13.

Comme illustré par la figure 1, l'aile 10 présente une largeur l1 plus importante que la largeur l2 de l'aile 11.As illustrated in FIG. 1, the wing 10 has a width l 1 greater than the width l 2 of the wing 11.

Avantageusement, le corps de l'élément de contact à déplacement d'isolant 1 peut être prolongé vers le bas par une patte 12 alignée (dans l'exemple décrit) sur l'axe vertical Δ. Cette patte 12 sert de prise de contact électrique avec un autre organe, par exemple un câble (non représenté) muni, en son extrémité, d'un élément de contact de forme complémentaire ou est inséré dans un trou métallisé d'une carte de circuit imprimé.Advantageously, the body of the insulating displacement contact element 1 can be extended downwards by a lug 12 aligned (in the example described) on the vertical axis Δ. This tab 12 serves as an electrical contact with another member, for example a cable (not shown) provided, at its end, with a contact element of complementary shape or is inserted into a metallized hole of a circuit board. printed.

La réalisation d'un tel élément de contact à déplacement d'isolant 1 est connue en soi. Il peut être obtenu, par exemple, par emboutissage dans une bande métallique aux caractéristiques physiques appropriées : épaisseur, élasticité, etc.The production of such an insulating displacement contact element 1 is known per se. It can be obtained, for example, by stamping in a metal strip with appropriate physical characteristics: thickness, elasticity, etc.

Comme illustré par les figures 2 et 3, ces éléments de contact à déplacement d'isolant sont montés dans des logements 21 prévus à cet effet, d'un bornier 2.As illustrated in FIGS. 2 and 3, these insulation displacement contact elements are mounted in housings 21 provided for this purpose, of a terminal block 2.

Plus précisément la figure 2 illustre un exemple de bornier 2, vu de côté, et la figure 3, ce même bornier 2, vu de haut. Sur cette dernière figure, on a réalisé des découpes verticales (sur la figure 2) dans le corps 20 du bornier 2 pour mieux mettre en évidences les dispositions particulières à l'invention.More precisely, FIG. 2 illustrates an example of terminal block 2, seen from the side, and FIG. 3, this same terminal block 2, seen from above. In this last figure, vertical cuts were made (in FIG. 2) in the body 20 of the terminal block 2 in order to better highlight the particular provisions of the invention.

En effet, selon une seconde caractéristique importante de l'invention, l'élément de contact à déplacement d'isolant 1, plan lors de sa réalisation (voir figure 1), est inséré dans des fentes d'insertion de câble 21 de manière à ce que les plans des ailes 10 et 11 fassent entre eux un angle β comme illustré plus particulièrement par la figure 3. Cet angle est compris dans la gamme 0 < β < 90°. Typiquement, β est de l'ordre de 40°.Indeed, according to a second important characteristic of the invention, the insulating displacement contact element 1, plane when it is produced (see FIG. 1), is inserted into cable insertion slots 21 so as to that the planes of the wings 10 and 11 make between them an angle β as illustrated more particularly by FIG. 3. This angle is included in the range 0 <β <90 °. Typically, β is of the order of 40 °.

Pour ce faire, le corps 20 de l'élément de contact à déplacement d'isolant 1 est muni, dans les fentes 21, de rainures borgnes, 200 et 201, de hauteurs suffisantes pour que les ailes, 10 et 11, puissent y être insérées. En outre, comme illustré plus particulièrement par la figure de détail 4, qui représente en écorché deux fentes 21 adjacentes, la rainure 200 s'étend parallèlement à un axe Δ2 orthogonal à un axe Δ', parallèle à la direction moyenne d'insertion de câbles 3 dans les fentes 21. La rainure 201 s'étend parallèlement à un axe Δ1 formant un angle β avec l'axe Δ'. Il s'ensuit que les ailes 10 et 11 forment entre elles le même angle β.To do this, the body 20 of the insulating displacement contact element 1 is provided, in the slots 21, with blind grooves, 200 and 201, of sufficient heights so that the wings, 10 and 11, can be there. inserted. In addition, as illustrated more particularly by the detail figure 4, which shows in cutaway two adjacent slots 21, the groove 200 extends parallel to an axis Δ 2 orthogonal to an axis Δ ', parallel to the mean direction of insertion. cables 3 in the slots 21. The groove 201 extends parallel to an axis Δ 1 forming an angle β with the axis Δ '. It follows that the wings 10 and 11 form between them the same angle β.

On conserve un certain jeu latéral pour l'aile 10 dans son logement (rainure 200). Il suffit, comme le montre plus particulièrement la figure 3, que les parois de la rainure 200 ne soient pas parallèles entre elles, en d'autres termes qu'elles présentent une légère divergence pour que la rainure 201 soit évasée en forme d'entonnoir.There is a certain lateral clearance for the wing 10 in its housing (groove 200). It suffices, as shown more particularly in FIG. 3, that the walls of the groove 200 are not parallel to each other, in other words that they have a slight divergence for the groove 201 to be flared in the form of a funnel. .

Enfin, l'aile 11 n'est pas insérée complètement dans la rainure 200 de manière à ce que son bord extérieur (droit sur les figures 3 et 4) ne touche pas la fond de cette rainure.Finally, the wing 11 is not completely inserted into the groove 200 so that its outer edge (straight in FIGS. 3 and 4) does not touch the bottom of this groove.

L'élément de contact à déplacement d'isolant 1 est donc cambré puis inséré à force dans la fente 21 et courbé du fait des caractéristiques géométriques particulières des rainures 200 et 201.The insulating displacement contact element 1 is therefore arched and then forcibly inserted into the slot 21 and curved due to the particular geometrical characteristics of the grooves 200 and 201.

En outre, on prévoit, de part et d'autre des rainures, 200 et 201, suivant l'axe Δ', deux paires butées verticales envis à vis, deux butées sur la paroi droite, 202 et 204, et deux sur la paroi gauche, 203 et 205. Ces butées vont servir au guidage et au maintien du câble 3 que l'on introduit dans la fente 21, en vue du dénudage local de la gaine 30 et de la création d'un contact galvanique entre l'âme 30 et l'élément de contact à déplacement d'isolant 1.In addition, there are provided, on either side of the grooves, 200 and 201, along the axis Δ ', two pairs of vertical stops envisaged with screws, two stops on the straight wall, 202 and 204, and two on the wall. left, 203 and 205. These stops will be used to guide and hold the cable 3 which is introduced into the slot 21, with a view to the local stripping of the sheath 30 and the creation of a galvanic contact between the core 30 and the insulating displacement contact element 1.

On va maintenant considérer deux cas illustrés par les figures 5 et 6, respectivement.We will now consider two cases illustrated by Figures 5 and 6, respectively.

Le premier cas concerne un câble de diamètre extérieur que l'on va qualifier de "faible". Cette notion est, naturellement, relative. On doit effectuer une corrélation entre le diamètre ou section du câble 3 et les dimensions de l'élément de contact à déplacement d'isolant 1, en particulier l'écartement "e" (figure 1) entre les ailes 10 et 11.The first case concerns a cable with an outside diameter which will be described as "small". This notion is, of course, relative. A correlation must be made between the diameter or section of the cable 3 and the dimensions of the insulating displacement contact element 1, in particular the spacing "e" (FIG. 1) between the wings 10 and 11.

Pour fixer les idées, on suppose que "e" est égal à 0,4 mm (ailes 10 et 11 dans un même plan, c'est-à-dire lors de la fabrication de l'élément de contact à déplacement d'isolant 1) et que l'épaisseur de la feuille métallique dont est issu l'élément de contact 1 est égale à 0,5. Si on suppose, en outre, que l'angle β est sensiblement égal à 40°, la distance résiduelle "e"' (voir figure 1) entre les bords d'attaque en vis à vis des deux ailes 10 et 11, formant lames, est réduite à environ 0,15 mm.To fix the ideas, it is assumed that " e " is equal to 0.4 mm (wings 10 and 11 in the same plane, that is to say during the manufacture of the contact element with displacement of insulation 1) and that the thickness of the metal sheet from which the contact element 1 is derived is equal to 0.5. If it is further assumed that the angle β is substantially equal to 40 °, the residual distance "e"'(see Figure 1) between the leading edges opposite the two wings 10 and 11, forming blades , is reduced to approximately 0.15 mm.

Pour les valeurs ci-dessus, on peut considérer qu'un câble de diamètre de l'ordre de 0,4 mm est un câble de "faible" section et répond au premier cas que l'on va détailler.For the above values, it can be considered that a cable with a diameter of the order of 0.4 mm is a cable of "small" section and responds to the first case which we will detail.

La figure 5 illustre le fonctionnement de l'élément de contact à déplacement d'isolant 1 pour ce premier cas.Figure 5 illustrates the operation of the insulating displacement contact element 1 for this first case.

Le câble 3 est introduit dans la fente 21 et, plus précisément, entre les deux lames, 10 et 11. Du fait de la forme évasée de l'extrémité supérieure de ces lames (figure 1 : 13), on obtient un effet de guidage et un positionnement précis du câble 3, rendant plus aisé son introduction dans l'interstice entre les lames, 10 et 11. Si on exerce une force dirigée vers le bas, le processus d'insertion en force entre les deux lames s'amorce. Le câble 3 est maintenu sensiblement rectiligne, aligné sur l'axe Δ', du fait de la présence des paires de butées verticales en vis à vis, 202-203 et 204-205, respectivement.The cable 3 is introduced into the slot 21 and, more precisely, between the two blades, 10 and 11. Due to the flared shape of the upper end of these blades (FIG. 1:13), a guiding effect is obtained. and precise positioning of the cable 3, making it easier to introduce it into the gap between the blades, 10 and 11. If a downward force is exerted, the process of force insertion between the two blades begins. The cable 3 is kept substantially rectilinear, aligned on the axis Δ ', due to the presence of the pairs of vertical stops opposite, 202-203 and 204-205, respectively.

La lame la plus large 10 est repoussée en flexion vers la paroi gauche (sur la figure 5) de la rainure 201 : position 10'. Elle peut venir éventuellement en butée sur la paroi gauche précitée. Simultanément, le bord d'attaque 100' de cette lame coupe la gaine isolante 31 et établit un contact galvanique avec l'âme 30 du câble 3.The widest blade 10 is pushed back in flexion towards the left wall (in FIG. 5) of the groove 201: position 10 '. It can possibly come into abutment on the aforementioned left wall. Simultaneously, the leading edge 100 'of this blade cuts the insulating sheath 31 and establishes galvanic contact with the core 30 of the cable 3.

Comme il a été indiqué, la section du câble 3 étant supposée "faible, la position de la lame la plus étroite 11, dont le plan est orthogonal à l'axe moyen Δ' d'insertion du câble 3, ne subit pas ou peu de changement. Le bord droit (sur la figure 5) reste éloigné du fond de la rainure 200. Cependant le bord d'attaque 110 coupe également la gaine isolante 31 du câble 3 et vient en contact galvanique avec l'âme 30 de ce câble 3. La lame 11 se comporte donc en poutre fixe, dans ce cas.As indicated, the section of the cable 3 being assumed to be "small, the position of the narrowest blade 11, the plane of which is orthogonal to the mean axis Δ 'of insertion of the cable 3, does not undergo or has little The straight edge (in FIG. 5) remains distant from the bottom of the groove 200. However, the leading edge 110 also cuts the insulating sheath 31 of the cable 3 and comes into galvanic contact with the core 30 of this cable. 3. The blade 11 therefore behaves as a fixed beam, in this case.

La coopération des deux lames a pour effet que la seconde lame, c'est-à-dire la lame 11, exerce un effet de coin sur le câble 3 et les points de coupe de la gaine isolante 31 sont décalés suivant l'axe Δ'. Cette disposition permet d'écarter les sections d'isolants coupées. Il y a bien dénudage local du câble 3, sur une épaisseur sensiblement égale à celle de l'élément de contact à déplacement d'isolant 1.The cooperation of the two blades has the effect that the second blade, that is to say the blade 11, exerts a wedge effect on the cable 3 and the cutting points of the insulating sheath 31 are offset along the axis Δ '. This arrangement makes it possible to separate the sections of cut insulation. There is indeed local stripping of the cable 3, over a thickness substantially equal to that of the insulating displacement contact element 1.

La position décalée des lames de coupe suivant l'axe du fil cause un décalage des entailles faites dans celui-ci, ce qui augmente la section de cuivre restante pour résister à l'arrachement. Il s'ensuit un moindre risque de rupture du fil.The offset position of the cutting blades along the axis of the wire causes an offset of the notches made in it, which increases the remaining copper section to resist tearing. This results in a lower risk of wire breakage.

Le second cas considéré est relatif à des câbles 3 de section dite "importante", c'est-à-dire comprise typiquement dans une gamme de 0,4 mm à 0,8 mm, toujours pour les dimensions précédemment énoncées d'élément de contact à déplacement d'isolant 1.The second case considered relates to cables 3 of so-called "large" section, that is to say typically comprised in a range of 0.4 mm to 0.8 mm, always for the previously stated dimensions of the element of insulation displacement contact 1.

Ce cas est illustré par la figure 6. Le mode opératoire est strictement le même que celui décrit en regard de la figure 5 et il est inutile de le redétailler. Comme précédemment, la seconde lame, c'est-à-dire la lame 10 fléchit de la rainure 201 (position 10"), ce jusqu'à la paroi gauche compte-tenu de la section plus importante du câble 3. En outre, la première lame, c'est-à-dire la lame 11, est sollicitée en translation et s'enfonce elle aussi dans son logement, c'est-à-dire dans la rainure 200, suivant l'axe Δ1. Selon la valeur plus ou moins importante de la section du câble 3, elle va s'enfoncer plus ou moins profondément dans cette rainure 200 jusqu'à venir en butée sur le fond de celle-ci : position 11', comme représentée sur la figure 6.This case is illustrated in FIG. 6. The operating mode is strictly the same as that described with regard to FIG. 5 and there is no need to detail it again. As before, the second blade, that is to say the blade 10 flexes from the groove 201 (position 10 "), this up to the left wall taking into account the larger section of the cable 3. In addition, the first blade, that is to say the blade 11, is biased in translation and also sinks into its housing, that is to say into the groove 200, along the axis Δ 1 . more or less important value of the section of the cable 3, it will sink more or less deeply into this groove 200 until it abuts on the bottom of the latter: position 11 ′, as shown in FIG. 6.

Comme précédemment, la coopération des deux lames a pour effet que la seconde lame, c'est-à-dire la lame 11 (position 11"), exerce un effet de coin sur le câble 3 et les points de coupe de la gaine isolante 31 sont décalés suivant l'axe Δ'. Cette disposition permet d'écarter les sections d'isolants coupées. Il y a bien dénudage local du câble 3, sur une épaisseur sensiblement égale à celle de l'élément de contact à déplacement d'isolant 1.As before, the cooperation of the two blades has the effect that the second blade, that is to say the blade 11 (position 11 "), exerts a wedge effect on the cable 3 and the cutting points of the insulating sheath 31 are offset along the axis Δ '. This arrangement makes it possible to separate the sections of cut insulation. There is indeed local stripping of the cable 3, over a thickness substantially equal to that of the displacement contact element insulator 1.

En résumé, il y a toujours cet effet de coin. En outre, la disposition des lames dissymétriques présente un avantage supplémentaire : elle permet une réduction du pas intercontacts, tout en conservant une largeur des lames suffisante.In summary, there is always this corner effect. In addition, the arrangement of asymmetrical blades has an additional advantage: it allows a reduction in the intercontact pitch, while retaining a sufficient width of the blades.

A la lecture de la description qui précède, on constate que l'invention atteint bien les buts qu'elle s'est fixés. Elle permet une égale efficacité de fonctionnement pour des câbles de différents diamètres, plus précisément des câbles de diamètres compris dans deux gammes, dites "faible" et "importante", relativement aux dimensions propres de l'élément de contact à déplacement d'isolant 1.On reading the above description, it can be seen that the invention does indeed achieve the goals which it has set for itself. It allows equal operating efficiency for cables of different diameters, more precisely cables of diameters included in two ranges, called "low" and "large", relative to the dimensions of the contact element with displacement of insulation 1 .

Cependant, il doit être clair que l'invention n'est pas limitée aux seuls exemples de réalisations précisément décrits, notamment en relation avec les figures 1 à 6. Notamment, les données numériques n'ont été précisées que pour mieux illustrer l'invention et ne sauraient limiter, en quoi que ce soit, sa portée.However, it should be clear that the invention is not limited to only the examples of embodiments precisely described, in particular in relation to FIGS. 1 to 6. In particular, the digital data have only been specified to better illustrate the invention and cannot in any way limit its scope.

Il doit être également clair que le nombre d'éléments de contact par bornier ou organe similaire n'est limité que par des considérations pratiques, ce nombre étant au minimum égal à l'unité. Il dépend de l'application précise pour laquelle le bornier est utilisé.It should also be clear that the number of contact elements per terminal block or similar member is limited only by practical considerations, this number being at least equal to unity. It depends on the precise application for which the terminal block is used.

Enfin, le nombre de rangées d'élément de contact à déplacement d'isolant n'est pas limité à l'unité. Par exemple, on pourrait concevoir un bornier (non représenté) avec deux rangées parallèles d'éléments de contact à déplacement d'isolant, disposés dans des fentes à pas décalé ou non.Finally, the number of rows of contact elements with insulation displacement is not limited to the unit. For example, one could design a terminal block (not shown) with two parallel rows of contact elements with insulation displacement, arranged in slots with offset or not.
