Definitions

  • the present invention relates generally to connectors of the kind comprising, in a body of insulating material, at least one insulation displacement contact member, that is to say at least one contact member which, for the connection of an electrical conductor, insulated or not, comprises itself, two arms delimiting between them a slot in which is simply forcibly engaged this electrical conductor.

For its connection, the conductor is threaded at an angle between the two lateral arms and the middle arm and is forced along the two slots.
  • the connection is reliable but requires a significant insertion force of the conductor along the two slots.

La présente invention concerne d'une manière générale les connecteurs du genre comportant, dans un corps en matière isolante, au moins un organe de contact autodénudant, c'est-à-dire au moins un organe de contact qui, pour le raccordement d'un conducteur électrique, isolé ou non, comporte lui-même, deux bras délimitant entre eux une fente dans laquelle est simplement engagé à force ce conducteur électrique.The present invention relates generally to connectors of the kind comprising, in a body of insulating material, at least one insulation displacement contact member, that is to say at least one contact member which, for the connection of an electrical conductor, insulated or not, comprises itself, two arms delimiting between them a slot in which is simply forcibly engaged this electrical conductor.

De tels connecteurs trouvent aussi bien leur application dans la constitution par exemple de socles de prise de courant, notamment pour courants faibles, que dans la constitution d'autres appareillages électriques, et, par exemple, dans celle d'éléments de répartiteur ou de sous-répartiteur téléphonique tels que tête de câble ou réglette.Such connectors find their application both in the constitution for example of socket outlets, in particular for low currents, as in the constitution of other electrical equipment, and, for example, in that of distributor or sub elements - telephone distributor such as cable head or strip.

En pratique, ces connecteurs comportent parallèlement les uns aux autres, plusieurs organes de contact autodénudants.In practice, these connectors comprise, parallel to each other, several insulation displacement contact members.

L'un des problèmes dans leur réalisation est donc d'en minimiser au mieux l'encombrement et de fiabiliser la connexion.One of the problems in their implementation is therefore to minimize the overall size and make the connection more reliable.

Le document EP-A-0 014 081 décrit un organe de contact autodénudant et plat, comportant trois bras délimitant entre eux deux fentes affectées à un même conducteur. Pour son raccordement, le conducteur est enfilé en biais entre les deux bras latéraux et le bras médian et est forcé le long des deux fentes. La connexion est fiable mais nécessite une force d'insertion importante du conducteur le long des deux fentes. L'organe de contact est relativement encombrant.Document EP-A-0 014 081 describes a flat insulation displacement contact member, comprising three arms delimiting between them two slots assigned to the same conductor. For its connection, the conductor is threaded at an angle between the two lateral arms and the middle arm and is forced along the two slots. The connection is reliable but requires a significant insertion force of the conductor along the two slots. The contact member is relatively bulky.

Le document EP-A-075 150 décrit un organe de contact multiple, comportant plusieurs branches de contact parallèles et solidaires les unes des autres et affectées chacune au raccordement d'un conducteur. Chaque branche de contact comporte une fente dans laquelle le conducteur est raccordé en prenant une position oblique, en particulier à 45°, relativement à la branche de contact. Les deux bords des branches, qui sont opposés à la fente de chaque branche sont légèrement pliées d'un côté et de l'autre de la branche et séparent les uns des autres les conducteurs raccordés dans les fentes et mutuellement connectés en parallèle. Sur une réglette le pas des organes de contact à branches de contact multiples est relativement important et conduit à une réglette relativement encombrante.Document EP-A-075 150 describes a multiple contact member, comprising several parallel contact branches integral with each other and each assigned to the connection of a conductor. Each contact branch has a slot in which the conductor is connected by taking an oblique position, in particular at 45 °, relative to the contact branch. The two edges branches, which are opposite the slot of each branch are slightly bent on one side and the other of the branch and separate from each other the conductors connected in the slots and mutually connected in parallel. On a strip the pitch of the contact members with multiple contact branches is relatively large and leads to a relatively bulky strip.

La présente invention a pour but de réduire l'encombrement des organes de contact en place dans le corps isolant du connecteur et d'améliorer la fiabilité de la connexion des conducteurs aux organes de contact.The present invention aims to reduce the size of the contact members in place in the insulating body of the connector and to improve the reliability of the connection of the conductors to the contact members.

Un tel socle de prise de courant 10 ne relevant pas de la présente invention, il n'est pas décrit dans tous ses détails ici.Since such a socket outlet 10 does not fall under the present invention, it is not described in all its details here.

On indique simplement qu'il comporte un corps 11, en matière isolante, qui, à l'avant, forme un alvéole 12, pour l'engagement d'une fiche complémentaire non représentée, et qui, à l'arrière, forme un connecteur 14, pour le raccordement d'un nombre déterminé de conducteurs électriques 15 (figure 7).It is simply indicated that it comprises a body 11, of insulating material, which, at the front, forms a cell 12, for the engagement of a complementary plug, not shown, and which, at the rear, forms a connector 14, for the connection of a determined number of electrical conductors 15 (FIG. 7).

Dans l'avéole 12 s'étend au moins une lamelle de contact 16, et, en correspondance, le connecteur 14 comporte au moins un organe de contact 17.In the aoleole 12 extends at least one contact strip 16, and, in correspondence, the connector 14 comprises at least one contact member 17.

En pratique, plusieurs lamelles de contact 16 sont prévues en parallèle dans l'alvéole 12, et le connecteur 14 comporte un nombre égal d'organes de contact 17, qui, disposés parallèlement les uns aux autres, sont chacun individuellement en liaison électrique avec les lamelles de contact 16 et reçoivent chacun un conducteur électrique 15, voire deux conducteurs électriques 15.In practice, several contact strips 16 are provided in parallel in the cell 12, and the connector 14 comprises an equal number of contact members 17, which, arranged parallel to each other, are each individually in electrical connection with the contact strips 16 and each receive an electrical conductor 15, or even two electrical conductors 15.

Les conducteurs électriques 15 sont des conducteurs électriques isolés, à âme conductrice 18 et gaine 19.The electrical conductors 15 are insulated electrical conductors, with conductive core 18 and sheath 19.

Les organes de contact 17 du connecteur 14 sont des organes de contact autodénudants, c'est-à-dire des organes de contact comportant, pour l'engagement à force d'un conducteur électrique 15, deux bras 20A, 20B délimitant entre eux une fente autodénudante 22. Dans la forme de réalisation représentée, ils sont associés par deux et forment un organe de contact double.The contact members 17 of the connector 14 are insulation displacement contact members, that is to say contact members comprising, for the force engagement of an electrical conductor 15, two arms 20A, 20B delimiting between them a insulation displacement slot 22. In the embodiment shown, they are associated in pairs and form a double contact member.

Les deux organes de contact 17 d'un organe de contact double sont en pratique issus d'une seule et même lame convenablement découpée et pliée. Ils ont en commun, d'une part, une barrette 23, qui les relie en parallèle à la lamelle de contact 16 correspondante, et, d'autre part, une charnière 24, qui est formée d'un simple retour en équerre de la partie médiane d'un bord de la lame initiale. Ils s'étendent respectivement de part et d'autre de cette barrette 23 et de cette charnière 24.The two contact members 17 of a double contact member come in practice from a single blade suitably cut and folded. They have in common, on the one hand, a strip 23, which connects them in parallel to the corresponding contact strip 16, and, on the other hand, a hinge 24, which is formed by a simple return to the square of the middle part of an edge of the initial blade. They extend respectively on either side of this bar 23 and of this hinge 24.

La fente 22 des organes de contact 17 est rectiligne. Elle s'étend suivant une direction d'allongement D1, schématisée en traits interrompus sur la figure 1, pour le seul organe de contact entièrement illustré.The slot 22 of the contact members 17 is rectilinear. It extends in a direction of elongation D1, shown schematically in broken lines in Figure 1, for the only fully illustrated contact member.

Suivant l'invention, à chacun des organes de contact 17 sont associés, suivant des dispositions décrites plus en détail ultérieurement, des moyens de conformation du conducteur, pour son raccordement dans la fente 22 et son application contre l'une et l'autre des faces opposées de l'organe de contact 17, d'un premier côté pour l'un des bras 20A, 20B, et du côté opposé au précédent pour l'autre bras, de part et d'autre de la fente.According to the invention, to each of the contact members 17 are associated, according to arrangements described in more detail later, means for shaping the conductor, for its connection in the slot 22 and its application against either of the opposite faces of the contact member 17, on a first side for one of the arms 20A, 20B, and on the opposite side to the previous one for the other arm, on either side of the slot.

Dans les figures 1 à 13, les moyens de conformation associés à l'organe de contact 17 comportent, sur chacun des bras 20A, 20B et la largeur de ces bras, un pan d'engagement 25 du conducteur, qui est incliné sur chaque bras en bout de la fente 22. Les deux pans 25 prolongent les bras et sont inclinés symétriquement d'un côté et de l'autre des bras. Ils définissent sur l'organe de contact une ligne de niveau L1, qui est sensiblement perpendiculaire à la direction D1 de la fente 22.In FIGS. 1 to 13, the shaping means associated with the contact member 17 comprise, on each of the arms 20A, 20B and the width of these arms, an engagement panel 25 of the conductor, which is inclined on each arm at the end of the slot 22. The two sides 25 extend the arms and are inclined symmetrically on one side and the other of the arms. They define on the contact member a level line L1, which is substantially perpendicular to the direction D1 of the slot 22.

Ainsi que représenté, pour chacun des bras 20A, 20B, le pan d'engagement 25 forme la partie inférieure d'une déformation locale 26 globalement hémicylindrique, dont les génératrices forment les lignes de niveau L1 et sont donc perpendiculaires à la direction d'allongement D1 de la fente 22, et dont la concavité est tournée d'un premier côté pour l'un de ces bras 20A, 20B, et du côté opposé au précédent pour l'autre de ceux-ci. Les concavités des deux déformations sont tournées en regard du plan des deux bras.As shown, for each of the arms 20A, 20B, the engagement panel 25 forms the lower part of a local semi-cylindrical deformation 26, the generatrix of which form the level lines L1 and are therefore perpendicular to the direction of elongation D1 of the slot 22, and the concavity of which is turned on a first side for one of these arms 20A, 20B, and on the opposite side to the previous one for the other of these. The concavities of the two deformations are turned opposite the plane of the two arms.

Autrement dit, pour le bras 20A par exemple, la déformation locale 26 fait saillie de manière convexe d'un premier côté, et, pour le bras 20B, elle fait saillie de manière convexe du côté opposé au précédent.In other words, for the arm 20A for example, the local deformation 26 protrudes convexly from a first side, and, for the arm 20B, it protrudes convexly from the side opposite to the previous one.

Ainsi, tel que schématisé par la figure 2, les déformations locales 26 forment en bout des deux bras 20A, 20B un canal 27, qui s'étend sur la largeur des deux bras perpendiculairement à la fente 22, et dans lequel doit être engagé le conducteur électrique 15 à raccorder dans la fente.Thus, as shown diagrammatically in FIG. 2, the local deformations 26 form at the end of the two arms 20A, 20B a channel 27, which extends over the width of the two arms perpendicular to the slot 22, and in which must be engaged the electrical conductor 15 to be connected in the slot.

Il en résulte que, lorsque ce conducteur électrique 15 est engagé longitudinalement dans ce canal 27, suivant la flèche F1 de la figure 1, et qu'il est ensuite engagé transversalement à force dans la fente 22, suivant la flèche F2 de la figure 5, il a tendance à prendre de lui-même une configuration en S pour laquelle, tel que représenté à la figure 5, d'une part, il s'étend contre le bras 20A, du côté de la concavité de la déformation locale 26 de celui-ci, et, d'autre part, il s'étend contre le bras 20B, du côté de la déformation locale 26 de ce bras 20B, et donc du côté opposé au précédent.It follows that, when this electrical conductor 15 is engaged longitudinally in this channel 27, along the arrow F1 of FIG. 1, and that it is then engaged transversely by force in the slot 22, along the arrow F2 of FIG. 5 , it tends to take on its own an S configuration for which, as shown in FIG. 5, on the one hand, it extends against the arm 20A, on the side of the concavity of the local deformation 26 of the latter, and, on the other hand, it extends against the arm 20B, on the side of the local deformation 26 of this arm 20B, and therefore on the side opposite to the previous one.

Dans la forme de réalisation selon les figures 1 à 10, les deux déformations locales se referment par un pontet 28 terminal sur les bras et le long du canal 27.In the embodiment according to FIGS. 1 to 10, the two local deformations are closed by a terminal bridge 28 on the arms and along the channel 27.

La robustesse de l'ensemble s'en trouve renforcée.The robustness of the whole is reinforced.

En pratique, le pontet 28 s'étend sensiblement suivant le plan de la lame initiale..In practice, the trigger guard 28 extends substantially along the plane of the initial blade.

Par ailleurs, dans cette réalisation, la fente résulte d'un simple cisaillage de la lame initiale.Furthermore, in this embodiment, the slot results from a simple shearing of the initial blade.

Préférentiellement, et tel que représenté, pour faciliter l'engagement à force d'un conducteur électrique 15, les lèvres 29 de la fente 22 sont décalées l'une par rapport à l'autre transversalement par rapport au plan des bras 20A, 20B, ainsi qu'il est mieux visible sur les figures 3 et 4.Preferably, and as shown, to facilitate the engagement by force of an electrical conductor 15, the lips 29 of the slot 22 are offset relative to each other transversely relative to the plane of the arms 20A, 20B, as best seen in Figures 3 and 4.

En pratique, le décalage l'une par rapport à l'autre des lèvres 29 de la fente 22 est suffisant pour que ces lèvres 29 laissent subsister entre elles un espace facilitant le passage de l'âme conductrice 18 d'un conducteur électrique 15, comme représenté à la figure 6.In practice, the offset relative to each other of the lips 29 of the slot 22 is sufficient for these lips 29 to leave a space between them which facilitates the passage of the conductive core 18 of an electrical conductor 15, as shown in figure 6.

Mais, globalement ces lèvres 29, qui sont formées par la tranche de la lame initiale entre les deux bras, s'étendent sensiblement perpendiculairement au plan des bras 20A, 20B et résultent d'une légère déformation des bords en vis-à-vis des bras, qui est faite d'un côté et de l'autre, respectivement.However, overall these lips 29, which are formed by the edge of the initial blade between the two arms, extend substantially perpendicular to the plane of the arms 20A, 20B and result from a slight deformation of the edges in opposite the arms, which is made on one side and the other, respectively.

Sur les figures 3, 4 et 6, l'épaisseur de la lame initiale a volontairement été exagérée. En outre, sur ces figures, les largeurs relatives des bras 20A, 20B ne sont pas respectées.In FIGS. 3, 4 and 6, the thickness of the initial blade has been deliberately exaggerated. In addition, in these figures, the relative widths of the arms 20A, 20B are not observed.

En outre, le bras 20A, qui est le bras le plus extérieur par rapport à la charnière 24, est bordé latéralement par un retour en équerre 30A formant couteau du côté de la concavité de la déformation locale 26.In addition, the arm 20A, which is the outermost arm relative to the hinge 24, is bordered laterally by a square return 30A forming a knife on the side of the concavity of the local deformation 26.

Ainsi que représenté dans les figures 7 à 10, les organes de contact 17 sont montés mobiles suivant sensiblement leur plan dans le corps 11, entre une position d'engagement du conducteur, figure 8, pour laquelle ils sont aptes à recevoir transversalement les conducteurs électriques 15, et une position de connexion, figure 10, pour laquelle chaque conducteur est engagé à force dans la fente 22.As shown in Figures 7 to 10, the contact members 17 are mounted movable along substantially their plane in the body 11, between a position of engagement of the conductor, Figure 8, for which they are adapted to receive transversely the electrical conductors 15, and a connection position, FIG. 10, for which each conductor is forcibly engaged in the slot 22.

Les moyens de conformation associés à chacun des organes de contact 17 comportent également en outre les flancs 32A, 32B d'une rainure 33 du corps 11, dans laquelle est monté mobile l'organe de contact 17. Ces flancs maintiennent le conducteur contre les bras de l'organe de contact, pendant la mise en position de connexion de ce dernier.The shaping means associated with each of the contact members 17 also further include the flanks 32A, 32B of a groove 33 of the body 11, in which the contact member 17 is movably mounted. These flanks hold the conductor against the arms of the contact member, during the connection position of the latter.

Dans la forme de réalisation représentée, chacun des organes de contact 17 est monté rotatif dans le corps 11, par déformation autour de la charnière 24.In the embodiment shown, each of the contact members 17 is rotatably mounted in the body 11, by deformation around the hinge 24.

Des canaux d'entrée 36 pour les conducteurs sont prévus sur la face arrière ou le dos du corps 11, dans la zone médiane en creux de celui-ci, pour l'engagement des conducteurs électriques 15, suivant les flèches coudées F3 de la figure 8 dans le canal 27 des organes de contact.Input channels 36 for the conductors are provided on the rear face or the back of the body 11, in the hollow central region thereof, for the engagement of the electrical conductors 15, according to the bent arrows F3 in the figure 8 in the channel 27 of the contact members.

Pour la sortie de la surlongueur des conducteurs électriques 15, le corps 11 comporte des perçages 35, qui, débouchent chacun dans l'une des rainures 33 en regard du canal 27 de l'organe de contact en position d'engagement dans cette rainure.For the output of the extra length of the electrical conductors 15, the body 11 has holes 35, which each open into one of the grooves 33 opposite the channel 27 of the contact member in the position of engagement in this groove.

Les perçages 35 sont sensiblement alignés sur une face dite supérieure, ainsi que sur une face dite inférieure du connecteur.The holes 35 are substantially aligned on a so-called upper face, as well as on a so-called lower face of the connector.

Enfin, dans la forme de réalisation représentée, chacun des organes de contact 17 fait saillie hors du corps 11, en position d'engagement, figure 8, du côté opposé au canal d'entrée 36 sur le connecteur 14.Finally, in the embodiment shown, each of the contact members 17 protrudes from the body 11, in the engagement position, FIG. 8, on the side opposite the inlet channel 36 on the connector 14.

Pour faciliter le pivotement des organes de contact 17, il est possible d'agir sur eux à l'aide d'une pince prenant appui sur le dos du corps 11, tel que schématisé par des flèches en ciseaux F4 sur la figure 8. La pince alors mise en oeuvre porte avantageusement sur les organes de contact 17 du côté de ceux-ci renforcé par le retour en équerre 30A formant couteau.To facilitate the pivoting of the contact members 17, it is possible to act on them using a clamp bearing on the back of the body 11, as shown diagrammatically by scissor arrows F4 in FIG. 8. The clamp then implemented advantageously relates to the contact members 17 on the side thereof reinforced by the return angle 30A forming a knife.

Dans la position d'engagement représentée sur la figure 8, les canaux 27 d'organes de contact 17 sont alignés avec les perçages 35 du corps 11.In the engagement position shown in FIG. 8, the channels 27 of contact members 17 are aligned with the holes 35 of the body 11.

Tel que schématisé par des flèches F3 sur cette figure 8, il est ainsi possible d'introduire par le canal d'entrée 36 chacun des conducteurs électriques 15 et de le pousser dans le canal 27 de l'organe de contact 17 et dans l'un des perçages 35 du corps 11.As shown schematically by arrows F3 in this FIG. 8, it is thus possible to introduce through the input channel 36 each of the electrical conductors 15 and to push it into the channel 27 of the contact member 17 and into the one of the holes 35 in the body 11.

Il suffit ensuite de faire pivoter ces organes de contact 17 de leur position d'engagement à leur position de connexion représentée sur la figure 10, pour le raccordement des conducteurs dans les fentes respectives.Then simply rotate these contact members 17 from their engagement position to their connection position shown in Figure 10, for connecting the conductors in the respective slots.

Du fait des moyens de conformation explicités précédemment, les conducteurs électriques 15 prennent alors chacun une configuration en S, de part et d'autre des organes de contact 17 avec lesquels ils sont en prise, en venant d'un côté contre l'un des bras et de l'autre côté contre l'autre bras.Due to the shaping means explained above, the electrical conductors 15 then each take an S-shaped configuration, on either side of the contact members 17 with which they are engaged, coming from one side against one of the arm and on the other side against the other arm.

Ils se trouvent conjointement sectionnés par le retour en équerre 30A formant couteau, avec élimination de leur bout en surplus, comme schématisé à la figure 5.They are jointly sectioned by the angle return 30A forming a knife, with elimination of their excess end, as shown diagrammatically in FIG. 5.

Dans la variante de réalisation représentée sur la figure 11, les lèvres 29 de la fente 22 des organes de contact 17 sont écartées l'une de l'autre suivant le plan des bras 20A, 20B. Elles restent sensiblement droites, perpendiculairement au plan des bras 20A, 20B.In the alternative embodiment shown in FIG. 11, the lips 29 of the slot 22 of the contact members 17 are spaced from one another along the plane of the arms 20A, 20B. They remain substantially straight, perpendicular to the plane of the arms 20A, 20B.

Il n'est pas de même dans la variante de réalisation représentée sur la figure 12, dans laquelle, au contraire, ces lèvres 29 s'étendent en biais par rapport au plan des bras 20A, 20B.It is not the same in the variant embodiment shown in FIG. 12, in which, on the contrary, these lips 29 extend at an angle relative to the plane of the arms 20A, 20B.

Dans la variante de réalisation représentée sur la figure 13, les déformations terminales sur les deux bras 20A, 20B de l'organe de contact 17 s'étendent librement de part et d'autre du plan des bras.In the alternative embodiment shown in FIG. 13, the terminal deformations on the two arms 20A, 20B of the contact member 17 extend freely on either side of the plane of the arms.

Autrement dit, il n'est pas prévu de pontet pour les relier. En outre, dans cette variante de réalisation, chaque pan d'engagement 25 est sensiblement plan, en s'étendant en oblique par rapport au plan du bras. Il est précédé d'un pan d'entrée 38, qui lui aussi est sensiblement plan, mais s'étend sensiblement parallèlement au plan de lame initiale et est écarté de l'autre par l'entrée 38.In other words, there is no provision for a bridge to connect them. In addition, in this alternative embodiment, each engagement face 25 is substantially plane, extending obliquely to the plane of the arm. It is preceded by an entry panel 38, which is also substantially flat, but extends substantially parallel to the plane of the initial blade and is spaced from the other by the entry 38.

Avec cette variante de réalisation, le conducteur électrique 15 à connecter peut si désiré être introduit entre les pans 38 et 25 suivant directement la direction d'allongement D1 de la fente 22.With this variant embodiment, the electrical conductor 15 to be connected can, if desired, be introduced between the sides 38 and 25 directly following the direction of elongation D1 of the slot 22.

Les figures 14 à 22 illustrent, à titre d'exemple, l'application de l'invention à un élément de répartiteur ou de sous-répartiteur téléphonique, tel que tête de câble ou réglette.Figures 14 to 22 illustrate, by way of example, the application of the invention to a telephone splitter or sub-distributor element, such as cable head or strip.

Comme précédemment, un tel élément constitue au moins localement un connecteur 44 comportant, dans un corps 41 en matière isolante, au moins un organe de contact 47 autodénudant, et, en pratique, disposés parallèlement les uns aux autres, plusieurs organes de contact 47 de ce type.As before, such an element constitutes at least locally a connector 44 comprising, in a body 41 made of insulating material, at least one insulation displacement contact member 47, and, in practice, arranged parallel to each other, several contact members 47 of this guy.

Comme précédemment, également, chaque organe de contact 47 comporte, pour le raccordement à force d'un conducteur électrique 15, deux bras 50A, 50B délimitant entre eux une fente 52. Il lui est associé des moyens de conformation, pour une application du conducteur électrique 15 contre ses bras 50A, 50B transversalement par rapport à la direction d'allongement D1 de sa fente 52, d'un premier côté pour l'un de ces bras 50A, 50B, et du côté opposé au précédent pour l'autre de ceux-ci.As before, also, each contact member 47 comprises, for the force connection of an electrical conductor 15, two arms 50A, 50B delimiting between them a slot 52. It is associated with means of conformation, for application of the conductor electric 15 against its arms 50A, 50B transversely to the direction of elongation D1 of its slot 52, on a first side for one of these arms 50A, 50B, and on the opposite side to the previous for the other of these.

En ce qui concerne l'organe de contact 47, les deux bras 50A, 50B sont issus d'une lame initiale d'un seul tenant et sont solidaires d'un pied 70 commun sur cette lame. La fente 52 est précédée par une entrée en Vé 71 du conducteur, comme représenté dans la figure 20, qui est terminale et ouverte entre les deux bras 50A, 50B. En variante, ainsi que schématisé en traits interrompus sur cette figure 20, l'entrée en Vé 71 est fermée par un pontet terminal 58 reliant les deux bras 58.As regards the contact member 47, the two arms 50A, 50B come from an initial blade in one piece and are integral with a common foot 70 on this blade. The slot 52 is preceded by a V-shaped entry 71 of the conductor, as shown in FIG. 20, which is terminal and open between the two arms 50A, 50B. As a variant, as shown diagrammatically in broken lines in this FIG. 20, the entry into Vé 71 is closed by a terminal bridge 58 connecting the two arms 58.

Les lèvres 59 de la fente 52 sont décalées l'une par rapport à l'autre transversalement par rapport au plan des bras 50A, 50B, ainsi qu'il est mieux visible sur la figure 21, et elles s'étendent en biais par rapport au plan de ces bras 50A, 50B. Elles sont en outre légèrement écartées l'une de l'autre suivant le plan des bras 50A, 50B.The lips 59 of the slot 52 are offset with respect to each other transversely to the plane of the arms 50A, 50B, as is better visible in FIG. 21, and they extend at an angle with respect to in the plane of these arms 50A, 50B. They are also slightly spaced from each other along the plane of the arms 50A, 50B.

Les moyens de conformation associés à chacun des organes de contact 47 ainsi constitués comportent, dans le corps 41, une rainure en S 73, ouverte en long sur une paroi 72 de celui-ci, en pratique une paroi frontale, dans laquelle l'organe de contact est monté en ayant la direction d'allongement D1 de la fente 52 centrée dans la rainure et s'étendant vers le fond de celle-ci.The shaping means associated with each of the contact members 47 thus formed comprise, in the body 41, an S-shaped groove 73, open lengthwise on a wall 72 thereof, in practice a front wall, in which the member contact is mounted having the direction of elongation D1 of the slot 52 centered in the groove and extending towards the bottom of the latter.

Cette rainure est délimitée entre deux flancs 74A, 74B qui sont globalement parallèles l'un à l'autre, et présentent l'un et l'autre un tronçon médian en biais entre les deux portions terminales droites de chacun. La fente est entre les deux tronçons en biais des deux flancs.This groove is delimited between two sides 74A, 74B which are generally parallel to one another, and each have a median section at an angle between the two straight end portions of each. The slot is between the two oblique sections of the two sides.

Le bras 50A est bordé localement par un retour en équerre 60A formant couteau.The arm 50A is bordered locally by a square return 60A forming a knife.

En outre l'autre bras 50B est lui-même bordé localement par au moins un retour en équerre 60B formant arrête-fil.In addition, the other arm 50B is itself locally bordered by at least one square return 60B forming a wire stopper.

En pratique, deux retours en équerre 60B formant arrête-fil sont prévus à distance l'un de l'autre sur le bras 50B. Ils s'étendent dans le même sens et sont en sens opposé par rapport au retour en équerre 60A formant couteau, en ayant une extension largement inférieure à celle du retour 60A.In practice, two square returns 60B forming a wire stopper are provided at a distance from each other on the arm 50B. They extend in the same direction and are in opposite directions with respect to the angle return 60A forming a knife, having an extension much less than that of the return 60A.

Les diverses rainures en S 73, que présente ainsi parallèlement les unes aux autres le corps 41, s'étendent sur toute la hauteur de celui-ci, en débouchant sur ses parois inférieure 76 et supérieure 77 à leurs extrémités.The various S-grooves 73, which the body 41 thus presents parallel to one another, extend over the entire height thereof, opening onto its lower 76 and upper 77 walls at their ends.

Au fond de chaque rainure en S 73, le corps 41 présente une saignée en Z 78, pour l'introduction par l'arrière du corps de l'organe de contact 47 correspondant, suivant la flèche F5 de la figure 18.At the bottom of each S-shaped groove 73, the body 41 has a Z-shaped groove 78, for the introduction from the rear of the body of the corresponding contact member 47, according to arrow F5 in FIG. 18.

L'ouverture des rainures en S 73 sur la paroi 72 est au moins localement préférentiellement arrondie, ou biseautée par des facettes, pour y faciliter l'introduction de conducteurs électriques 15, suivant les flèches F6 des figures 14 et 18.The opening of the S-grooves 73 on the wall 72 is at least locally preferably rounded, or bevelled by facets, to facilitate the introduction of electrical conductors 15 there, according to the arrows F6 of FIGS. 14 and 18.

Dans chacune des rainures en S 73, les deux bras 50A, 50B de l'organe de contact 47 sont respectivement en appui sur les portions terminales opposées de l'un et l'autre des flancs 74A, 74B respectivement de cette rainure en S 73, c'est-à-dire sur les portions terminales dites internes qui sont pratiquement alignées. Les retours en équerre 60A, 60B de ces bras 50A, 50B s'étendent chacun transversalement dans la rainure, en direction des portions terminales dites externes des flancs, qui sont les plus écartées l'une de l'autre.In each of the S-grooves 73, the two arms 50A, 50B of the contact member 47 are respectively supported on the opposite end portions of one and the other of the sides 74A, 74B respectively of this S-groove 73 , that is to say on the so-called internal terminal portions which are practically aligned. The angled returns 60A, 60B of these arms 50A, 50B each extend transversely in the groove, in the direction of the so-called external end portions of the sides, which are the most spaced from one another.

En pratique, le retour en équerre 60A formant couteau occulte sur toute la largeur la rainure en S 73, tandis que les retours en équerre 60B formant arrête-fil ne s'étendent que sur une fraction de la largeur de la rainure.In practice, the angled return 60A forming a hidden knife over the entire width of the S-groove 73, while the angle returns 60B forming a wire stopper extend only over a fraction of the width of the groove.

Chaque conducteur électrique 15 est introduit isolément, de front, dans la rainure en S 73 du corps 41, suivant les flèches F6 des figures 14 et 18, et engagé à force dans la fente 52 de l'organe de contact 47 présent dans cette rainure en S 73.Each electrical conductor 15 is introduced in isolation, from the front, into the S-groove 73 of the body 41, along the arrows F6 of FIGS. 14 and 18, and forcibly engaged in the slot 52 of the contact member 47 present in this groove in S 73.

Si désiré, cette introduction peut être facilitée par un outil, non représenté, dont la tranche, fendue en son milieu, a une configuration analogue à celle d'une telle rainure en S 73, et qui est utilisé pour pousser sur le conducteur électrique 15.If desired, this introduction can be facilitated by a tool, not shown, whose edge, split in the middle, has a configuration similar to that of such an S 73 groove, and which is used to push on the electrical conductor 15 .

Au terme de cette introduction, le conducteur électrique 15 se trouve localement dénudé par l'organe de contact 47 au droit de la fente 52 de celui-ci, tel que représenté sur la figure 22, avec contact de son âme conductrice 18 avec les lèvres 59 de cette fente 52. Il se trouve ainsi appliqué contre la face d'un bras et celle opposée de l'autre bras par les deux portions les plus écartées l'une de l'autre et dites externes desdits 74A, 74B, de part et d'autre de la fente 52 qu'il traverse.At the end of this introduction, the electrical conductor 15 is locally stripped by the contact member 47 in line with the slot 52 thereof, as shown in Figure 22, with contact of its conductive core 18 with the lips 59 of this slot 52. It is thus applied against the face of one arm and that opposite of the other arm by the two portions most spaced from each other and said external of said 74A, 74B, on the and on the other side of the slot 52 which it crosses.

Conjointement, il se trouve retenu, du côté de la paroi inférieure 76 du corps 41, entre les retours en équerre 60B formant arrête-fil, cependant que, du côté opposé, et donc du côté sortie, c'est-à-dire du côté par exemple de la paroi supérieure 77 du corps 41, et tel que schématisé en traits interrompus sur la figure 22, il se trouve dûment sectionné par le retour en équerre 60A occultant l'extrémité correspondante de la rainure en S 73 et formant couteau. Il se trouve appliqué contre la face d'un bras et celle opposée de l'autre bras par les flancs externes desdites branches 74A, 74B, de part et d'autre de la fente 52 qu'il traverse.Jointly, it is retained, on the side of the bottom wall 76 of the body 41, between the angle returns 60B forming a wire stopper, however, on the opposite side, and therefore on the outlet side, that is to say of the side for example of the upper wall 77 of the body 41, and as shown diagrammatically in broken lines in FIG. 22, it is duly sectioned by the square return 60A obscuring the corresponding end of the S-groove 73 and forming a knife. It is applied against the face of one arm and that opposite of the other arm by the external flanks of said branches 74A, 74B, on either side of the slot 52 which it crosses.

Les figures 23 à 26 représentent une variante de réalisation du connecteur selon l'invention, donnée par rapport aux figures 14 à 22.Figures 23 to 26 show an alternative embodiment of the connector according to the invention, given with reference to Figures 14 to 22.

Le connecteur selon cette variante est désigné par la référence 84.The connector according to this variant is designated by the reference 84.

Il comporte comme précédemment un corps isolant 81, au moins un organe de contact 87 autodénudant et des moyens de conformation décrits ci-après pour l'application du conducteur non représenté contre l'organe de contact. En pratique, plusieurs organes de contact 87 sont disposés parallèlement les uns aux autres dans le corps.As before, it comprises an insulating body 81, at least one insulation displacement contact member 87 and means of shaping described below for applying the conductor not shown against the contact member. In practice, several contact members 87 are arranged parallel to each other in the body.

L'organe de contact 87 comporte deux bras 80A, 80B délimitant entre eux une fente autodénudante 82 et définissant une entrée en Vé pour le conducteur en bout de la fente. Il est obtenu à partir d'une lame plate initiale qui est convenablement pliée et découpée.The contact member 87 comprises two arms 80A, 80B delimiting between them an insulation displacement slot 82 and defining an entry into a V for the conductor at the end of the slot. It is obtained from an initial flat blade which is suitably folded and cut.

Les bras 80A, 80B sont solidaires d'un pied 80, au-delà de la fente. Celui-ci présente dans cette réalisation une excroissance latérale 80C, qui est déformée et entaillée et forme un contact de pression élastique avec un autre organe de contact identique 87', reçu contre le précédent en venant en vis-à-vis de lui selon une disposition tête bêche, ainsi qu'illustré partiellement en pointillés dans la figure 25. Cet autre contact peut appartenir à un autre connecteur 84' analogue au connecteur 84 et s'emboitant partiellement dans celui-ci.The arms 80A, 80B are integral with a foot 80, beyond the slot. The latter has in this embodiment a lateral protuberance 80C, which is deformed and notched and forms an elastic pressure contact with another identical contact member 87 ', received against the previous one coming opposite it according to a head to tail arrangement, as illustrated partially in dotted lines in FIG. 25. This other contact may belong to another connector 84 ′ similar to connector 84 and partially fitting into it.

Les deux lèvres telles que 89 de la fente 82 sont en biais par rapport au plan des bras et sensiblement parallèles et en vis-à-vis l'une de l'autre.The two lips such as 89 of the slot 82 are at an angle with respect to the plane of the arms and substantially parallel and opposite one another.

L'organe de contact 87 présente deux retours en équerre 90A et 90B.The contact member 87 has two square returns 90A and 90B.

Ces deux retours en équerre sont de sens opposé l'un par rapport à l'autre, en étant par ailleurs sensiblement identiques l'un à l'autre. Ils s'étendent sur la longueur des bras, le long des bords opposés à ceux délimitant la fente et légèrement au-delà sur une partie de la longueur du pied 80. Une échancrure 91A, 91B terminale sur chacun des retours en équerre 90A, 90B, réduit sa largeur sur la partie terminale de chaque bras. Un crevage sensiblement sur la partie médiane de chaque retour en équerre, de grande largeur à ce niveau, définit un ergot de butée 92A, 92B saillant en biais sur la face intérieure du retour en équerre, pour la retenue de l'organe de contact en place dans le corps isolant.These two square returns are in opposite directions with respect to one another, being moreover substantially identical to each other. They extend over the length of the arms, along the edges opposite those delimiting the slot and slightly beyond over a part of the length of the foot 80. A notch 91A, 91B terminal on each of the square returns 90A, 90B , reduces its width on the end part of each arm. A puncture markedly on the middle part of each angled return, very wide at this level, defines a stop lug 92A, 92B projecting at an angle on the inside face of the angled return, for retaining the contact member in place in the insulating body .

Le corps isolant 81 comporte, pour chaque organe de contact, une rainure 83 affectée à son montage et à l'accès à sa fente pour le raccordement d'un conducteur, non représenté, et en pratique une pluralité de rainures parallèles pour les différents organes de contact. Ces rainures 83 sont ouvertes en long sur l'une des faces du corps isolant et débouchent sur deux autres faces opposées l'une à l'autre. Elles s'étendent en profondeur dans le corps sensiblement sur la longueur des bras et de la fente. Elles se prolongent différemment dans le corps, pour le pied 80 de chaque organe de contact et l'accès à l'excroissance latérale du pied, vers la face opposé à celle d'ouverture de la rainure 83.The insulating body 81 comprises, for each contact member, a groove 83 assigned to its mounting and to the access to its slot for the connection of a conductor, not shown, and in practice a plurality of parallel grooves for the different members of contact. These grooves 83 are open lengthwise on one of the faces of the insulating body and lead to two other faces opposite one another. They extend deep into the body substantially along the length of the arms and the slot. They extend differently in the body, for the foot 80 of each contact member and the access to the lateral protuberance of the foot, towards the face opposite that of the opening of the groove 83.

Ces rainures 83 sont parallèles les unes autres et sont délimités chacune entre deux flancs 84A, 84B en vis-à-vis dans le corps isolant.These grooves 83 are parallel to each other and are each delimited between two sides 84A, 84B facing each other in the insulating body.

A la différence des rainures de la réalisation précédente selon les figures 14 à 22, les rainures 83 sont en biais dans le corps.Unlike the grooves of the previous embodiment according to Figures 14 to 22, the grooves 83 are biased in the body.

L'organe de contact 87 en place dans sa rainure 83 s'étend sensiblement de l'une des portions terminales à l'autre et prend une position transversale dans le corps, comme dans la réalisation précédente. Les deux retours en équerre occultent totalement par leur partie large et partiellement par leur partie plus étroite les deux portions terminales de la rainure. Ces retours en équerre sont parallèles aux faces d'extrémité sur lesquelles débouchent les extrémités des rainures. Ils rigidifient l'organe de contact en place pour faciliter le raccordement du conducteur.The contact member 87 in place in its groove 83 extends substantially from one of the terminal portions to the other and takes a transverse position in the body, as in the previous embodiment. The two angled returns completely obscure by their wide part and partially by their narrower part the two end portions of the groove. These square returns are parallel to the end faces on which the ends of the grooves open. They stiffen the contact member in place to facilitate connection of the conductor.

Pour cette disposition et le maintien de l'organe de contact, le flanc 84A présente un portion 85A sensiblement en S dans l'une des portions quasi terminales de la rainure et l'autre flanc 84B présente parallèlement une portion 85B sensiblement en S dans l'autre des portions quasi terminales de la rainure. Les parties médianes de ces deux portions en S 85A et 85B sont planes et parallèles, en étant transversales aux faces du corps sur lesquelles s'ouvrent les rainures et débouchent leurs extrémités. Elles sont distantes l'une de l'autre le long de la rainure et écartées l'une de l'autre transversalement de l'épaisseur de l'organe de contact. Elles servent de surfaces d'appui aux deux bras 80A et 80B de l'organe de contact, dont les faces, dites extérieures relativement aux retours en équerre partant des bras, sont en partie reçues contre elles. Les deux parties d'extrémité de chaque portion sensiblement en S 85A, 85B, qui sont situées de part et d'autre la partie médiane précitée, forment deux transitions sur le flanc 84A, 84B. Ces transitions sont parallèles l'une à l'autre, en étant et ainsi qu'illustré légèrement arquées ou en variante planes.For this arrangement and the maintenance of the contact member, the flank 84A has a portion 85A substantially in S in one of the almost terminal portions of the groove and the other flank 84B has in parallel a portion 85B substantially in S in the 'other of the almost terminal portions of the groove. The middle parts of these two portions in S 85A and 85B are planar and parallel, being transverse to the faces of the body on which the grooves open and open their ends. They are spaced from each other along the groove and spaced from each other transversely of the thickness of the contact member. They serve as bearing surfaces for the two arms 80A and 80B of the contact member, the faces of which, said to be external relative to the square returns from the arms, are partly received against them. The two end parts of each substantially S-shaped portion 85A, 85B, which are located on either side of the aforementioned middle part, form two transitions on the sidewall 84A, 84B. These transitions are parallel to each other, being and as illustrated slightly arched or alternatively planar.

Ainsi, les deux bras 80A et 80B de l'organe de contact 87 s'appuient d'une part, sur une partie de leur largeur, contre les deux portions sensiblement en S 85A et 85B des deux flancs 84A et 84B, respectivement, et s'étendent d'autre part par ailleurs librement dans la rainure. La fente 82 est centrée entre ces portions sensiblement en S 85A et 85B et dans la rainure 83.Thus, the two arms 80A and 80B of the contact member 87 bear on the one hand, over part of their width, against the two substantially S-shaped portions 85A and 85B of the two sides 84A and 84B, respectively, and on the other hand extend freely in the groove. The slot 82 is centered between these portions substantially at S 85A and 85B and in the groove 83.

Exclusion faite de chacune des portions sensiblement en S 85A et 85B sur les flancs, ce sont ces flancs en biais par rapport à l'organe de contact qui assurent l'application du conducteur contre l'un et l'autre des bras 80A et 80B, de part et d'autre de la fente 82 et d'un côté de l'un des bras et de l'autre côté de l'autre bras. On précise en outre que chaque conducteur est maintenu pincé par la partie terminale étroite des retours en équerre 90A, 90B. Son extrémité saillante hors du connecteur est éliminée en la sectionnnant à l'aide d'un outil de coupe, pour lequel la partie large du retour en équerre de ce côté constitue un couteau fixe d'appui.Excluding each of the portions substantially in S 85A and 85B on the flanks, it is these flanks at an angle relative to the contact member which ensure the application of the conductor against both of the arms 80A and 80B , on either side of the slot 82 and on one side of one of the arms and on the other side of the other arm. It is further specified that each conductor is kept pinched by the narrow end part of the square returns 90A, 90B. Its protruding end outside the connector is eliminated by cutting it off using a cutting tool, for which the wide part of the angled return on this side constitutes a fixed support knife.

La partie interne 86 du corps isolant définit le niveau du fond arrondi 83F de chacune des rainures 83 et sert d'appui aux deux ergots de crevage 92A et 92B de l'organe de contat. Elle est elle-même fendue de part en part par une série de saignées 88 en Z, parallèles les unes aux autres et traversantes, ainsi que montré dans la figure 23 dans laquelle l'une des rainures est sans organe de contact en place dans cette rainure. Ces saignées reçoivent le pied 80 et les parties larges des retours en équerre 80A et 80B bordant partiellement le pied.The internal part 86 of the insulating body defines the level of the rounded bottom 83F of each of the grooves 83 and serves to support the two puncture pins 92A and 92B of the contact member. It is itself split right through by a series of grooves 88 in Z, parallel to each other and through, as shown in Figure 23 in which one of the grooves is without contact member in place in this groove. These grooves receive the foot 80 and the wide portions of the square returns 80A and 80B partially bordering the foot.

Les figures 27 à 32 correspondent à une autre variante de réalisation du connecteur selon l'invention donnée par rapport à la réalisation selon les figures 14 à 22 ou 23 à 26.FIGS. 27 to 32 correspond to another variant embodiment of the connector according to the invention given with respect to the embodiment according to FIGS. 14 to 22 or 23 to 26.

Ce connecteur est désigné globalement sous la référence 104. Il comporte un corps isolant 101, des organes de contact identiques 107 montés parallèlement dans le corps et des moyens pour appliquer les conducteurs non représentés contre l'organe de contact auquel chacun d'eux est raccordé.This connector is generally designated by reference 104. It comprises an insulating body 101, identical contact members 107 mounted parallel in the body and means for applying the conductors not shown against the contact member to which each of them is connected. .

L'organe de contact 107 comporte deux bras 110A et 110B délimitant entre elles une fente autodénudante 112 ayant une entrée en Vé en bout des bras pour le conducteur. Il comporte également un pied 110, opposé aux deux bras qui lui sont solidaires, et une excroissance latérale 110C d'un seul côté du pied. Il présente en outre une portion intermédiaire 114 entre le pied et les deux bras.The contact member 107 comprises two arms 110A and 110B delimiting between them a self-stripping slot 112 having a V-shaped entry at the end of the arms for the driver. It also includes a foot 110, opposite the two arms which are integral with it, and a lateral projection 110C on one side of the foot. It also has an intermediate portion 114 between the foot and the two arms.

Les lèvres de la fente sont en biais.The lips of the slit are angled.

Deux retours 120A et 120B pliés en sens opposé l'un de l'autre sont prévus respectivement le long des deux bras et de la portion intermédiaire 114. Une échancrure 121A, 121B sur la partie terminale de chaque retour plié réduit sa largeur sur la partie terminale de chaque bras et se termine par un chanfrein 125A, 125B sur l'extrémité du bras. Un crevage est prévu sur la partie large de chaque retour plié et forme un ergot 122A, 122B saillant en biais de butée, sur la face intérieure de celui-ci.Two returns 120A and 120B folded in opposite directions from each other are provided respectively along the two arms and of the intermediate portion 114. A notch 121A, 121B on the end portion of each folded return reduces its width on the portion end of each arm and ends with a chamfer 125A, 125B on the end of the arm. A a puncture is provided on the wide part of each folded return and forms a lug 122A, 122B projecting at an abutment bias, on the inside of the latter.

Les différences essentielles par rapport à l'organe de contact de l'une des réalisations précédentes selon les figures 14 à 22 et 23 à 26 sont précisées.The essential differences with respect to the contact member of one of the preceding embodiments according to FIGS. 14 to 22 and 23 to 26 are clarified.

Les deux bras 110A et 110B sont sensiblement dans un même plan, mais ceux-ci et la partie de jonction sont en biais par rapport au pied. Ceci est obtenu par une déformation locale 126A, 126B, de chaque côté du pied, autour de son axe longitudinal passant par la fente 112, pour tordre les bras et la partie de jonction en leur donnant cette disposition en biais par rapport au pied.The two arms 110A and 110B are substantially in the same plane, but these and the junction part are at an angle relative to the foot. This is obtained by a local deformation 126A, 126B, on each side of the foot, around its longitudinal axis passing through the slot 112, to twist the arms and the joining part by giving them this arrangement at an angle to the foot.

Les retours pliés 120A et 120B ne sont plus en équerre, mais forment un angle aigu avec les bras respectifs, en donnant à leur niveau une section en Z à l'organe de contact, ce Z étant vu retourné dans les figures 27 et 30.The folded returns 120A and 120B are no longer square, but form an acute angle with the respective arms, giving their level a Z section to the contact member, this Z being seen turned over in FIGS. 27 and 30.

Le corps isolant 101 comporte, pour chaque organe de contact 107, une rainure 103 ouverte en long sur l'une des faces du corps. Les rainures pour les différents organes de contact sont parallèles les unes aux autres et débouchent d'un côté et de l'autre sur le corps. Elles s'étendent en profondeur dans le corps sensiblement sur la longueur des bras et de la fente 112.The insulating body 101 comprises, for each contact member 107, a groove 103 open lengthwise on one of the faces of the body. The grooves for the various contact members are parallel to each other and open on one side and on the other on the body. They extend deep into the body substantially over the length of the arms and of the slot 112.

Ainsi que montré dans la figure 27, dans laquelle l'une des rainures est sans organe de contact en place, et dans la figure 28, les rainures 103 communiquent individuellement avec des saignées 108 en Z prévues dans la partie médiane 109 du corps, ces saignées débouchant chacune dans le fond de l'une des rainures 103. Les ergots de crevage 122A et 122B viennent en butée sur cette partie médiane échancrée d'un côté et de l'autre en 109A et 109B. Ces saignées en Z 108 communiquent elles-mêmes avec des rainures 111 opposées aux rainures 103.As shown in FIG. 27, in which one of the grooves has no contact member in place, and in FIG. 28, the grooves 103 communicate individually with grooves 108 in Z provided in the middle part 109 of the body, these grooves each emerging in the bottom of one of the grooves 103. The puncture pins 122A and 122B abut on this middle part notched on one side and the other at 109A and 109B. These Z grooves 108 communicate themselves with grooves 111 opposite the grooves 103.

A la différence des rainures des réalisations précédentes selon les figures 14 à 22 et 23 à 26, les rainures 103 sont droites sur la face concernée du corps isolant 101. Les deux bras 110A et 110B s'étendent sensiblement d'une portion terminale à l'autre de chaque rainure et prennent une position oblique dans celles-ci. La fente 112 est centrée dans la rainure et s'étend selon la profondeur de cette rainure. Les deux retours pliés 120A et 120B occultent partiellement par leur partie étroite et totalement par leur partie large les portions terminales de chaque rainure 103, la transition entre leurs parties large et étroite se situant sensiblement au niveau du fond de chaque rainure.Unlike the grooves of the previous embodiments according to FIGS. 14 to 22 and 23 to 26, the grooves 103 are straight on the face concerned of the insulating body 101. The two arms 110A and 110B extend substantially from a terminal portion to the 'other of each groove and take an oblique position therein. The slot 112 is centered in the groove and extends along the depth of this groove. The two folded returns 120A and 120B partially obscure by their narrow part and totally by their wide part the end portions of each groove 103, the transition between their wide and narrow parts being located substantially at the bottom of each groove.

Pour le maintien de chaque organe de contact 107 dans sa rainure 103, les deux flancs en vis-à-vis 104A et 104B qui délimitent cette rainure sont essentiellement droits mais pourvus localement chacun de deux déflecteurs 105A et 106A, 105B et 106B qui sont saillants dans la rainure. Les deux déflecteurs sur l'un des flancs sont situés sur l'une des portions terminales de la rainure, tandis que ceux sur l'autre flanc sont situés sur l'autre portion terminale de la rainure. Sur chaque flanc, les deux déflecteurs sont sensiblement à la suite l'un de l'autre et définissent entre eux et en allant vers la portion centrale de la rainure une protubérance locale sensiblement en S. Ils retiennent en appui entre eux l'arête saillante de pliage du retour sur chaque bras et les parties attenantes du retour et du bras, qui sont de part et d'autre de cette arête. Ainsi, la fente 112 et l'autre partie de chaque bras sont libres dans la portion médiane de la rainure, entre les deux déflecteurs de l'un des flancs et ceux de l'autre flanc.To maintain each contact member 107 in its groove 103, the two facing sides 104A and 104B which delimit this groove are essentially straight but locally provided each with two deflectors 105A and 106A, 105B and 106B which are projecting in the groove. The two deflectors on one of the sides are located on one of the end portions of the groove, while those on the other side are located on the other end portion of the groove. On each flank, the two deflectors are substantially one after the other and define between them and going towards the central portion of the groove a local protuberance substantially in S. They retain in support between them the projecting edge folding the return on each arm and the adjoining parts of the return and the arm, which are on either side of this edge. Thus, the slot 112 and the other part of each arm are free in the middle portion of the groove, between the two deflectors of one of the sides and those of the other side.

Ce sont dans ces conditions, les parties droites des flancs qui appliquent le conducteur contre l'organe de contact de part et d'autre de la fente 112, en ménageant d'un côté de l'un des bras et de l'autre côté de l'autre bras un espace de largeur réduite pour le conducteur traversant la fente.It is under these conditions, the straight sides of the flanks which apply the conductor against the contact member on either side of the slot 112, leaving one side of one of the arms and the other side the other arm a space of reduced width for the conductor passing through the slot.

En variante par rapport à l'une ou l'autre des figures 20, 26 et 32, on indique que l'organe de contact peut être double, c'est-à-dire formé de deux organes de contact, d'un seul tenant et sans pied sur chacun d'eux, qui sont alors de préférence directement tête-bêche. Le corps du connecteur est alors adapté en conséquence de manière symétrique par rapport au plan transversal médian d'un tel organe de contact double.As a variant with respect to one or other of FIGS. 20, 26 and 32, it is indicated that the contact member may be double, that is to say formed of two contact members, of a single standing and without feet on each of them, which are then preferably directly upside down. The body of the connector is then adapted accordingly symmetrically with respect to the median transverse plane of such a double contact member.

Cette dernière variante est représentée dans les figures 33 et 34 en ce qui concerne l'organe de contact double déduit de l'organe de contact selon les figures 30 et 31, dans la figure 35, en ce qui concerne le connecteur équipé d'au moins un organe de contact double de ce type, cette figure 35 étant elle-même déduite de la figure 28.This latter variant is represented in FIGS. 33 and 34 as regards the double contact member deduced from the contact member according to FIGS. 30 and 31, in FIG. 35, as regards the connector equipped with minus a double contact member of this type, this figure 35 being itself deduced from FIG. 28.

Sur ces figures 33 à 35, les références identiques à celles utilisées dans les figures 30, 31 et 28 désignent les mêmes éléments. Elles ont simplement été accompagnées du signe "prime" pour traduire la symétrie existant par rapport au plan transversal médian de l'organe de contact double, c'est-à-dire par rapport à la partie de jonction 114 sur l'organe de contact double et à la partie interne 109 du corps isolant.In these figures 33 to 35, the references identical to those used in Figures 30, 31 and 28 denote the same elements. They have simply been accompanied by the sign "prime" to translate the existing symmetry with respect to the median transverse plane of the double contact member, that is to say with respect to the junction part 114 on the contact member double and to the internal part 109 of the insulating body.

Cet organe de contact double et le connecteur ainsi équipé ne sont donc plus décrits.This double contact member and the connector thus equipped are therefore no longer described.

En se référant plus particulièrement à la figure 34, on voit que l'organe de contact double comporte en outre trois trous 130, 131A et 131B alignés sensiblement sur l'axe transversal de symétrie et réalisés à travers la partie de jonction et les deux retours pliés. Ces trous peuvent recevoir un fil conducteur nu, relativement rigide, qui est enfilé dans l'organe de contact et lui est ainsi raccordé.Referring more particularly to FIG. 34, it can be seen that the double contact member further comprises three holes 130, 131A and 131B aligned substantially on the transverse axis of symmetry and produced through the junction part and the two returns folded. These holes can receive a relatively rigid bare conducting wire which is threaded into the contact member and is thus connected to it.

Ces trous sont prévus pour d'une part faciliter l'insertion de ce fil et d'autre part assurer la tenue en place du fil. Ils sont définis par une forme circulaire 132 pour l'entrée du fil, qui est ouverte sur une lumière allongée et plus étroite 133, ainsi que référencé sur le seul trou 130.These holes are provided on the one hand to facilitate the insertion of this wire and on the other hand to ensure the holding in place of the wire. They are defined by a circular shape 132 for the entry of the wire, which is open on an elongated and narrower lumen 133, as referenced on the single hole 130.

Il leur correspond deux trous 135, 136 dans le corps du connecteur. Les deux trous illustrés de part et d'autre des trous 135 ou 136 sont des trous nécessaires au moulage du corps du connecteur.They have two holes 135, 136 in the connector body. The two holes illustrated on either side of the holes 135 or 136 are holes necessary for molding the body of the connector.

Une disposition analogue peut bien entendu être adoptée sur l'organe de contact des figures 30 à 32 à travers ses deux retours et sa partie de jonction au pied et en correspondance dans le corps du connecteur équipé de ces organes de contact.A similar arrangement can of course be adopted on the contact member of FIGS. 30 to 32 through its two returns and its junction part at the foot and in correspondence in the body of the connector equipped with these contact members.
