Description

La présente invention concerne un dispositif de connexion pour fil électrique comportant une fente de dénudage et de retenue.The present invention relates to a wire connection device having a stripping and retaining slot.

Un tel dispositif vise à assurer le raccordement électrique et l'immobilisation d'au moins un fil électrique gainé d'isolant, sans exiger un dénudage préalable de ce fil.Such a device is intended to ensure the electrical connection and the immobilization of at least one electrical wire wrapped with insulation, without requiring prior stripping of this wire.

De tels dispositifs de connexion sont habituellement mis en oeuvre pour raccorder des fils entre eux, par exemple dans des blocs de jonction, ou pour raccorder des fils à un équipement électrique, tel un organe de commande.Such connection devices are usually used to connect wires together, for example in terminal blocks, or to connect wires to electrical equipment, such as a controller.

Il est déjà connu des documents US5000698 ou US4988311 de réaliser des dispositifs comportant une fente dénudante ménagée dans une pièce conductrice. La fente présente, à l'une de ses extrémités, une embouchure évasée destinée à faciliter l'insertion du fil à raccorder dans la pièce conductrice, et à assurer une coupe transversale de l'isolant entourant l'âme conductrice du fil. Le fil est présenté transversalement par rapport à la fente puis déplacé dans le sens longitudinal de la fente, tout en conservant lui-même une orientation transversale à la fente.It is already known documents US5000698 or US4988311 to provide devices having a stripping slot in a conductive part. The slot has, at one of its ends, a flared mouth intended to facilitate the insertion of the wire to be connected in the conductive part, and to ensure a transverse section of the insulation surrounding the conductive core of the wire. The wire is presented transversely to the slot and then moved in the longitudinal direction of the slot, while maintaining itself a transverse orientation to the slot.

L'âme conductrice du fil, après dénudage local de celui-ci, vient en contact avec les bords de la fente qui l'immobilise par pression, et qui assure une continuité électrique entre l'âme conductrice et la pièce conductrice.The conductive core of the wire, after local stripping thereof, comes into contact with the edges of the slot which immobilizes it by pressure, and which provides electrical continuity between the conductive core and the conductive part.

Plusieurs dispositifs de connexion connus utilisent ce principe. Dans le document EP 0 247 360 , on trouve une borne de connexion qui comporte une pièce conductrice de connexion à fente rectiligne de dénudage et de retenue immobilisée dans un logement d'un boîtier isolant lui-même doté d'une ouverture qui comprend une lumière rectiligne de retenue de gaine surmontée par une ouverture d'introduction de fil. La fente est longitudinalement ménagée le long d'une partie en forme de profilé présentant une section polygonale creuse pour le guidage en translation d'un embout d'outil destiné à coulisser de part et d'autre entre les plis délimitant les bords de la fente de manière à pouvoir enfoncer un fil dans cette fente en position transversale par rapport à la fente et en se guidant dans la cavité interne de la partie profilée. Pour réaliser ici une connexion, il est nécessaire d'avoir un outil spécialement adapté.Several known connection devices use this principle. In the document EP 0 247 360 there is a connection terminal which comprises a conductive connecting piece having a linear stripping and retaining slot immobilized in a housing of an insulating housing itself having an opening which comprises a rectilinear sheath-retaining light surmounted by a wire introduction opening. The slot is longitudinally arranged along a section-shaped portion having a hollow polygonal section for the translational guidance of a tool tip intended to slide on either side between the folds delimiting the edges of the slot so as to be able to drive a wire in this slot in the transverse position relative to the slot and by guiding in the internal cavity of the profiled part. To make a connection here, it is necessary to have a specially adapted tool.

Il est également connu d'avoir un dispositif de connexion à fente de dénudage dans lequel le raccordement peut se faire à l'aide d'un outil classique tel un tournevis. C'est le cas par exemple dans le document EP 0 697 749 .It is also known to have a stripping slot connection device in which the connection can be made using a conventional tool such as a screwdriver. This is the case for example in the document EP 0 697 749 .

Le brevet FR 2 611 406 , au nom de la Demanderesse comme les deux autres documents cités précédemment, prévoit quant à lui une pièce de manoeuvre moulée avec le boîtier destinée à servir de poussoir pour faire glisser l'extrémité du fil entre les bords de la fente de dénudage. D'autres documents décrivent d'autres exemples de manières permettant l'introduction de l'extrémité du fil pour réaliser la connexion auto-dénudante.The patent FR 2 611 406 , in the name of the Applicant as the other two documents cited above, provides meanwhile a molded actuating piece with the housing to serve as a pusher to slide the end of the wire between the edges of the stripping slot. Other documents describe other examples of ways to introduce the end of the wire to make the self-stripping connection.

Le document US 5 000 698 décrit un dispositif de connexion qui comporte une pièce conductrice de connexion à fente rectiligne de dénudage et un boîtier qui comprend d'une part un logement pour un fil et d'autre part une ouverture de largeur correspondante à la pièce conductrice. Dans ce cas la lame est mobile par rapport au boîtier et peut être introduite dans le boîtier par un mouvement de translation.The document US 5,000,698 discloses a connection device which comprises a conductive connecting piece with straight stripping slot and a housing which comprises on the one hand a housing for a wire and on the other hand an opening of corresponding width to the conductive part. In this case the blade is movable relative to the housing and can be introduced into the housing by a translational movement.

Dans les dispositifs de connexion connus, la pièce conductrice de connexion doit assurer tout d'abord le dénudage du fil et ensuite un bon contact électrique. Elle doit alors présenter des qualités électriques de bonne conductivité mais aussi des qualités mécaniques afin de garantir la découpe de la gaine du fil et une force de contact suffisant pour avoir un contact fiable. Les matériaux connus pouvant être bons conducteurs ne présentent pas les caractéristiques mécaniques souhaitées, notamment d'un point de vue élasticité, pour permettre un bon dénudage et une force de contact satisfaisante.In the known connection devices, the conductive connection piece must first ensure the stripping of the wire and then a good electrical contact. It must then have electrical qualities of good conductivity but also mechanical properties to ensure the cutting of the wire sheath and sufficient contact force to have a reliable contact. The known materials that can be good conductors do not have the desired mechanical characteristics, especially from an elasticity point of view, to allow good stripping and a satisfactory contact force.

Lorsque la pièce conductrice est destinée à recevoir des extrémités de fils qui ont tous un même diamètre, il est possible d'adapter la forme de la pièce de connexion de telle sorte qu'en choisissant un matériau présentant de bonnes, voire d'excellentes qualités électriques on arrive à un bon dénudage et une force de contact optimisée.When the conductive part is intended to receive wire ends that all have the same diameter, it is possible to adapt the shape of the connecting piece so that by choosing a material having good or excellent qualities electric we arrive at a good stripping and an optimized contact force.

Toutefois, lorsque la pièce de connexion est destinée à recevoir des extrémités de fil de différents diamètres, compris dans une plage donnée, il devient difficile et même impossible d'avoir à la fois d'excellents résultats d'un point de vue électrique et d'un point de vue mécanique. La solution adoptée consiste alors à réaliser un compromis et à fabriquer la pièce conductrice de connexion dans un matériau qui présente des qualités mécaniques et électriques satisfaisantes sans être toutefois optimales. Ceci oblige à utiliser des alliages à base de cuivre et d'acier qui sont d'un prix de revient relativement élevé.However, when the connecting piece is intended to receive wire ends of different diameters, within a given range, it becomes difficult and even impossible to have both excellent results from an electrical point of view and from a mechanical point of view. The solution adopted is then to make a compromise and to manufacture the conductive part of connection in a material that has satisfactory mechanical and electrical properties but is not optimal. This requires the use of alloys based on copper and steel which are relatively high cost.

La présente invention a alors pour but de fournir un dispositif de connexion ne nécessitant pas l'utilisation d'un matériau onéreux tout en permettant d'avoir des propriétés électriques et mécaniques satisfaisantes, voire très satisfaisantes pour permettre un bon raccordement de fils de différents diamètres. Ce dispositif permettra avantageusement de réaliser le raccordement d'un fil à l'aide d'un tournevis.The present invention therefore aims to provide a connection device that does not require the use of an expensive material while allowing to have satisfactory electrical and mechanical properties, or very satisfactory to allow a good connection of son of different diameters . This device will advantageously make the connection of a wire with a screwdriver.

A cet effet, le dispositif proposé est un dispositif de connexion pour fil électrique selon le contenu de la revendication 1. Des caractéristiques additionnelles sont décrites dans les revendications dépendantes.For this purpose, the proposed device is an electrical wire connection device according to the content of claim 1. Additional features are described in the dependent claims.

On réalise ainsi un dispositif ne nécessitant pas la mise en oeuvre de matériaux onéreux. La pièce de connexion est réalisée dans un matériau qui est bon conducteur, tandis que les moyens de maintien et éventuellement de serrage sont réalisés dans un matériau résistant mécaniquement et qui donne la rigidité mécanique nécessaire au dispositif de connexion pour réaliser une bonne connexion électrique. Grâce aux moyens de maintien et éventuellement de serrage, ce nouveau dispositif de connexion auto-dénudante accepte, dans une plage donnée, des fils de diamètres sensiblement différents. Pour les fils de plus faible diamètre un maintien des bords de la fente au niveau de l'embouchure est suffisant tandis que pour des fils de diamètre plus important, un serrage sera nécessaire pour assurer un bon contact électrique.This produces a device that does not require the use of expensive materials. The connecting piece is made of a material that is good conductor, while the holding means and possibly clamping are made of a mechanically resistant material and gives the necessary mechanical rigidity to the connection device to achieve a good electrical connection. Thanks to the retaining means and possibly clamping, this new self-stripping connection device accepts, in a given range, son of substantially different diameters. For smaller diameter wires, maintaining the edges of the slot at the mouth is sufficient while for larger diameter wires, clamping will be necessary to ensure good electrical contact.

Selon le diamètre du fil connecté, la force d'appui sera plus ou moins importante, induisant un maintien ou un serrage des bords de la fente sur le fil.Depending on the diameter of the connected wire, the bearing force will be more or less important, inducing a holding or clamping of the edges of the slot on the wire.

Le raccordement s'effectue pour un opérateur extérieur comme s'il réalisait une connexion vissée, sauf qu'il est ici inutile de dénuder le fil à connecter.The connection is made for an outside operator as if he made a screw connection, except that there is no need to strip the wire to be connected.

Les figures 1 à 4 montrent une première forme de réalisation d'un dispositif selon l'invention, comportant une lyre auto-dénudante 1 repliée à l'une de ses extrémités et présentant une fente 9 ainsi qu'une embouchure 11, et une pièce appelée cage 21. Cette dernière est de forme parallélépipédique. Elle présente un premier logement 23 cylindrique circulaire s'étendant perpendiculairement au plan de l'extrémité repliée de la lyre 1 et destiné à recevoir un fil à connecter 3. La cage 21 présente également un second logement 25 se présentant sous la forme d'une fente ménagée dans la cage 21 dans le prolongement de l'extrémité repliée de la lyre auto-dénudante 1. Un troisième logement 27, qui est taraudé, est prévu pour l'entraînement en translation et le guidage de la cage 21. Les figures 3 et 4 montrent le dispositif de connexion de la figure 1 en position montée dans un boîtier isolant 29.The Figures 1 to 4 show a first embodiment of a device according to the invention, comprising a self-stripping lyre 1 folded at one of its ends and having a slot 9 and a mouth 11, and a part called cage 21. This The last is parallelepipedic. It has a first circular cylindrical housing 23 extending perpendicular to the plane of the folded end of the lyre 1 and intended to receive a wire to connect 3. The cage 21 also has a second housing 25 in the form of a slit formed in the cage 21 in the extension of the folded end of the self-stripping wand 1. A third housing 27, which is threaded, is provided for the drive in translation and guiding the cage 21. The Figures 3 and 4 show the connection device of the figure 1 in position mounted in an insulating housing 29.

La figure 3 montre en coupe le dispositif de connexion dans son boîtier isolant 29 avant connexion du fil 3. La cage 21 est placée au-dessus de la lyre de telle sorte que l'extrémité de la partie repliée de la lyre 1 se trouve à peine introduite dans le logement 25 de la cage 21. Le fil 3 est engagé à fond dans le logement 23. Une vis 31 est vissée dans le logement 27 taraudé. Cette vis 31 est montée de telle sorte que, lorsqu'on vient la visser, la cage 21 est repoussée vers la lyre 1. Le fil 3, prisonnier dans le logement 23, vient alors s'engager dans l'embouchure 11 de la lyre puis après être dénudé au niveau de cette embouchure 11 vient s'introduire dans la fente de dénudage et de retenue 9. On arrive alors à la position représentée sur la figure 4 en vue extérieure. La connexion est alors réalisée. Le logement 25 en forme de fente dans la cage 21 est d'une largeur telle que les bords extérieurs 33 de la lyre viennent prendre appui dans la cage 21 dans la position connectée de la figure 4. La largeur de cette fente 25 n'est pas forcément constante sur toute la longueur de celle-ci. La fente 25 peut par exemple être rétrécie au fond, vers l'intérieur de la cage 21. Ainsi, on garantit une bonne pression de contact des bords de la fente de dénudage et de retenue 9 sur l'âme conductrice du fil 3, quel que soit le diamètre du fil connecté.The figure 3 shows in section the connection device in its insulating housing 29 before connection of the wire 3. The cage 21 is placed above the lyre so that the end of the folded portion of the lyre 1 is just introduced into the housing 25 of the cage 21. The wire 3 is fully engaged in the housing 23. A screw 31 is screwed into the housing 27 threaded. This screw 31 is mounted so that when it is screwed, the cage 21 is pushed towards the lyre 1. The wire 3, trapped in the housing 23, then engages in the mouth 11 of the lyre and after being stripped at this mouth 11 is introduced into the stripping slot and retaining 9. It then arrives at the position shown on the figure 4 in external view. The connection is then made. The slot 25 in the form of a slot in the cage 21 is of a width such that the outer edges 33 of the lyre come to bear in the cage 21 in the connected position of the figure 4 . The width of this slot 25 is not necessarily constant over the entire length thereof. The slot 25 may for example be narrowed at the bottom, towards the inside of the cage 21. Thus, it ensures a good contact pressure of the edges of the stripping and retaining slot 9 on the conductive core of the wire 3, which regardless of the diameter of the wire connected.

Une seconde forme de réalisation d'un dispositif de connexion est représenté sur les figures 5 à 7. Ce dispositif comporte une pièce de connexion 2, une cage 4, deux fils à connecter 6 et 8, et une vis 10.A second embodiment of a connection device is shown on the Figures 5 to 7 . This device comprises a connection piece 2, a cage 4, two son to be connected 6 and 8, and a screw 10.

La pièce de connexion 2 est obtenue par découpage et pliage d'une bande métallique. Une première partie de la pièce de connexion forme une lame 12. A une extrémité de cette lame 12 s'étendent, perpendiculairement à cette lame, à partir des bords longitudinaux de cette lame 12, des pattes 14 qui se font face. Les deux bords longitudinaux 16 sont amincis et repliés vers l'autre patte 14. On forme ainsi deux fentes de dénudage et de retenue entre les pattes 14. A l'opposé de la lame 12, ces fentes de dénudage et de retenue présentent une embouchure évasée 18.The connection piece 2 is obtained by cutting and folding a metal strip. A first portion of the connecting piece forms a blade 12. At one end of this blade 12 extend, perpendicular to this blade, from the longitudinal edges of this blade 12, lugs 14 which face each other. The two longitudinal edges 16 are tapered and folded towards the other lug 14. Thus two stripping and retaining slots are formed between the lugs 14. At the opposite of the blade 12, these stripping and retaining slots have a mouth flared 18.

La cage 4 comporte une partie profilée de section rectangulaire. La largeur intérieure de ce profilé permet de loger la pièce de connexion 2 au niveau des pattes 14 en laissant uniquement un léger jeu entre ces pattes 14 et les parois longitudinales de la partie profilée 20. La pièce profilée 20 est une pièce tubulaire de section rectangulaire allongée. Les fentes de dénudage et de retenue s'étendent perpendiculairement à l'axe de la partie profilée 20 et parallèlement aux grands côtés de cette partie profilée.The cage 4 comprises a profiled portion of rectangular section. The internal width of this section makes it possible to house the connection piece 2 at the tabs 14 leaving only a slight clearance between these tabs 14 and the longitudinal walls of the profiled part 20. The profiled part 20 is a tubular piece of rectangular section elongate. The stripping and retaining slots extend perpendicular to the axis of the profiled portion 20 and parallel to the long sides of this profiled portion.

La hauteur intérieure de la partie profilée 20 correspond sensiblement à la hauteur de la pièce de connexion 2 au niveau des pattes 14 augmentée du diamètre des fils 6 et 8. Un cache 22 est prévu sur la cage 4 pour permettre de délimiter un logement réservé aux fils à connecter 6 et 8.The internal height of the profiled portion 20 substantially corresponds to the height of the connection piece 2 at the tabs 14 increased by the diameter of the son 6 and 8. A cover 22 is provided on the cage 4 to allow delimiting a housing reserved for wires to be connected 6 and 8.

Un petit côté de la partie profilée 20 de la cage 4 se trouve ainsi du côté de la pièce de connexion 2 et l'autre petit côté de la partie profilée 20 de la cage 4 se trouve du côté des fils à connecter. Du côté de la pièce de connexion 2, la cage présente un trou taraudé 24 dans lequel vient prendre place la vis 10. Sur le côté opposé au côté sur lequel est pratiqué le trou taraudé 24, se trouve une ouverture permettant le passage et le guidage des pattes 14.A small side of the profiled portion 20 of the cage 4 is thus side of the connecting piece 2 and the other small side of the profiled portion 20 of the cage 4 is on the side of the son to be connected. On the side of the connection piece 2, the cage has a threaded hole 24 in which the screw 10 is positioned. On the side opposite the side on which the threaded hole 24 is made, there is an opening allowing the passage and the guiding legs 14.

La vis 10 présente une tête 26 qui vient en butée contre une paroi 28 d'un boîtier isolant contenant le dispositif de connexion représenté aux figures 5 à 7.The screw 10 has a head 26 which abuts against a wall 28 of an insulating housing containing the connection device shown in FIGS. Figures 5 to 7 .

Ainsi, pour réaliser une connexion, un fil ou deux fils 6 et 8 comme représentés sur les figures 5 à 7, sont introduits dans la cage parallèlement à l'axe de la partie profilée 20 de cette cage. Les fils 6 et 8 sont placés dans le logement qui leur est réservé dans la cage 4. Les fentes de dénudage et de retenue de la pièce de connexion 2 s'étendent alors perpendiculairement aux fils à connecter 6 et 8. Pour réaliser la connexion, on vient visser la vis 10. Ce vissage a pour conséquence un entraînement en translation de la cage 4 vers la paroi de boîtier 28. La tige de la vis pénètre dans la cage 4 et pousse la pièce de connexion sur les fils 6 et 8. Ces derniers pénètrent alors entre les pattes 14 provoquant ainsi localement leur dénudage. Les pattes 14 viennent prendre appui sur les parois longitudinales de la partie profilée 20. Cette partie profilée est avantageusement réalisée en acier pour assurer une résistance suffisante. La pièce de connexion, quant à elle, est par exemple réalisée dans un alliage à base de cuivre pour garantir une bonne conduction électrique. En fin de vissage, les extrémités libres des pattes 14, au niveau des embouchures 18, viennent contre la paroi opposée à la paroi munie du trou taraudé 24. La course de la cage 4 est suffisante pour que les embouchures 18 traversent cette paroi. Ceci est possible grâce aux ouvertures réalisées dans celle-ci. Le passage des embouchures 18 dans les ouvertures de passage et de guidage réalisées dans la paroi de la partie profilée 20 permet de bien maintenir les pattes 14 en contact électrique avec les fils 6 et 8. Si ces fils sont des fils de diamètre assez important, ils auront tendance à écarter les pattes 14. Le passage des embouchures 18 dans les ouvertures de guidage permet alors de resserrer éventuellement les pattes 14 l'une vers l'autre de manière à assurer un bon contact électrique.Thus, to make a connection, a wire or two son 6 and 8 as shown on the Figures 5 to 7 , are introduced into the cage parallel to the axis of the profiled portion 20 of this cage. The son 6 and 8 are placed in the housing reserved for them in the cage 4. The stripping and retaining slots of the connection piece 2 then extend perpendicularly to the son to be connected 6 and 8. To make the connection, the screw 10 is screwed in. This screwing results in a drive in translation of the cage 4 towards the housing wall 28. The rod of the screw enters the cage 4 and pushes the connection piece onto the wires 6 and 8. The latter then penetrate between the tabs 14 thus causing local stripping. The tabs 14 come to bear on the longitudinal walls of the profiled portion 20. This profiled portion is advantageously made of steel to ensure sufficient strength. The connecting piece, for its part, is for example made of a copper-based alloy to ensure good electrical conduction. At the end of screwing, the free ends of the lugs 14, at the mouths 18, come against the wall opposite the wall provided with the tapped hole 24. The stroke of the cage 4 is sufficient for the mouths 18 to pass through this wall. This is possible thanks to the openings made in it. The passage of the mouths 18 in the passage openings and guiding made in the wall of the profiled portion 20 makes it possible to keep the tabs 14 in electrical contact with the son 6 and 8. If these son are son of significant diameter, they will tend to spread the tabs 14. The passage of the mouths 18 in the guide openings then allows to possibly tighten the tabs 14 towards each other so as to ensure good electrical contact.

Dans cette forme de réalisation aussi, une pièce indépendante de la lame 12 et de la pièce de connexion 2 (qui peut donc facilement être réalisée dans un autre matériau) assure sur les fils 6 et 8 une force de maintien ou de serrage perpendiculairement aux bords des fentes de dénudage et de retenue et autorise la connexion de fils de diamètres différents avec toujours un bon contact électrique.In this embodiment also, an independent piece of the blade 12 and the connecting piece 2 (which can therefore easily be made of another material) provides on the son 6 and 8 a holding force or clamping perpendicularly to the edges of the stripping and retaining slots and allows the connection of wires of different diameters with always a good electrical contact.

Les figures 8A à 8C et 9A à 9C représentent une variante de réalisation du dispositif représenté sur les figures 5 à 7. Les pièces de cette troisième forme de réalisation similaires aux pièces constitutives du dispositif de connexion de la seconde forme de réalisation reprendront les mêmes références augmentées du nombre 100.The FIGS. 8A to 8C and 9A to 9C represent an alternative embodiment of the device shown in Figures 5 to 7 . The parts of this third embodiment similar to the component parts of the connection device of the second embodiment will have the same references increased by the number 100.

On retrouve dans cette troisième forme de réalisation une pièce de connexion 102, une cage 104, un fil 106 et une vis 110. La pièce de connexion présente également une lame 112 et des pattes 114. Ici, seul un bord longitudinal 116 de chaque patte 114 est replié vers l'autre patte 114 de telle sorte que l'on a qu'une seule fente de dénudage et de retenue 130. Cette fente 130 présente une embouchure 118.In this third embodiment, there is a connecting piece 102, a cage 104, a wire 106 and a screw 110. The connecting piece also has a blade 112 and tabs 114. Here, only a longitudinal edge 116 of each leg 114 is folded towards the other leg 114 so that only one stripping and retaining slot 130 is present. This slot 130 has a mouth 118.

Ici, avant de réaliser une connexion, la pièce de connexion 102 est placée à l'extérieur de la cage 104. De ce fait, les dimensions de la cage 104 sont inférieures à celles de la cage 4. On retrouve toutefois une même largeur intérieure de la cage 104, à savoir que cette largeur correspond à la largeur de la pièce de connexion 102 au niveau des pattes 114 augmentée d'un léger jeu. Ainsi, lorsque le fil 106 se trouve dans la fente 130, il a tendance à écarter les pattes 114 l'une de l'autre et celles-ci peuvent alors prendre appui sur les parois longitudinales de la partie profilée 120 évitant ainsi une trop forte déformation des pattes 114 et garantissant un bon maintien ou serrage des bords de la fente de dénudage et de retenue 130 sur le fil 106. La longueur de la section rectangulaire de la partie profilée 120 de la cage correspond donc sensiblement à la place nécessaire pour loger un ou plusieurs fils à connecter.Here, before making a connection, the connecting piece 102 is placed outside the cage 104. As a result, the dimensions of the cage 104 are smaller than those of the cage 4. There is, however, the same internal width of the cage 104, namely that this width corresponds to the width of the connection piece 102 at the tabs 114 increased by a slight clearance. Thus, when the wire 106 is in the slot 130, it tends to spread the tabs 114 of one another and they can then bear on the longitudinal walls of the profiled portion 120 thus avoiding excessive deformation of the tabs 114 and ensuring a good retention or tightening of the edges of the stripping slot and retaining 130 on the wire 106. The length of the rectangular section of the profiled portion 120 of the cage therefore substantially corresponds to the space required to accommodate one or more son to connect.

La partie profilée 120, présente sur deux côtés opposés des ouvertures 132 permettant le passage et le guidage des pattes 114. Ainsi, ces pattes 114 peuvent traverser la partie profilée 120 de part en part.The profiled portion 120, has on two opposite sides of the openings 132 allowing the passage and guiding of the tabs 114. Thus, these tabs 114 can pass through the profiled portion 120 from one side.

La cage 104 présente également une patte 134 repliée à son extrémité qui sert ainsi de support à la vis 110 qui s'étend parallèlement à la fente 130 de dénudage et de retenue mais, par rapport à la cage 104, du côté opposé à la pièce de connexion 102.The cage 104 also has a tab 134 folded at its end which thus serves as a support for the screw 110 which extends parallel to the slot 130 stripping and retaining but, relative to the cage 104, the side opposite the piece connection 102.

Les figures 8A et 9A montrent le dispositif de connexion avant l'opération de raccordement. Le fil 106 est introduit dans la partie profilée 120. L'embouchure 118 de la fente de dénudage et de retenue 130 se trouve juste au niveau d'une ouverture 132 de guidage. Le reste de la pièce de connexion 102 est à l'extérieur de la cage 104. La tête 126 de la vis vient en appui contre la paroi 128 de boîtier.The Figures 8A and 9A show the connection device before the connection operation. The wire 106 is introduced into the profiled portion 120. The mouth 118 of the stripping and retaining slot 130 is just at a guide opening 132. The remainder of the connecting piece 102 is outside the cage 104. The head 126 of the screw bears against the wall 128 of the housing.

Les figures 8B et 9B montrent le dispositif en cours de raccordement. La vis a été tournée à l'aide d'un tournevis non représenté. Les pattes 114 de la pièce de connexion 102 pénètrent dans la cage 104 et la gaine isolante du fil à connecter 106 est entamé au niveau de l'embouchure 118 de la fente de dénudage et de retenue 130. Le fait que cette embouchure 118 soit évasée permet un bon centrage du fil par rapport à la fente 130.The Figures 8B and 9B show the device being connected. The screw was turned with a screwdriver not shown. The tabs 114 of the connecting piece 102 penetrate into the cage 104 and the insulating sheath of the wire to be connected 106 is engaged at the mouth 118 of the stripping and retaining slot 130. The fact that this mouth 118 is flared allows a good centering of the wire relative to the slot 130.

Les figures 8C et 9C montrent le dispositif en fin de connexion. La vis 110 est en fin de course et elle a repoussé entièrement la cage 104 par l'intermédiaire de la patte 134 sur la pièce de connexion 102 qui traverse de part en part la cage 104 en passant par les ouvertures 132. Les pattes 114 de la pièce de connexion 102 sont alors parfaitement maintenues et assurent ainsi un bon contact électrique avec l'âme conductrice du fil 106, quel que soit le diamètre de ce fil (dans une plage donnée).The Figures 8C and 9C show the device at the end of the connection. The screw 110 is at the end of the stroke and it has pushed the cage 104 completely through the tab 134 on the connection piece 102 which passes right through the cage 104 through the openings 132. The tabs 114 of FIG. the connecting piece 102 are then perfectly maintained and thus ensure good electrical contact with the conductive core of the wire 106, whatever the diameter of this wire (in a given range).

Les divers dispositifs dé connexion décrits ci-dessus sont des dispositifs de connexion ne nécessitant pas la mise en oeuvre de matériau onéreux. On réalise dans ces dispositifs de connexion un découplage des fonctions mécanique et électrique. La pièce de connexion assure une bonne liaison électrique tandis que la plaque ou la cage assure une bonne rigidité permettant d'avoir une force au niveau des points de contact suffisante pour un bon contact électrique dans une plage donnée de diamètres de fils à connecter.The various connection devices described above are connection devices that do not require the use of expensive material. In these connection devices, the mechanical and electrical functions are decoupled. The connection piece provides a good electrical connection while the plate or the cage provides good rigidity to have a force at the points of contact sufficient for good electrical contact in a given range of wire diameters to connect.

Comme le montrent les première, deuxième et troisième formes de réalisation, un tel dispositif de connexion permet de réaliser une connexion auto-dénudante en réalisant un mouvement de vissage. Ce mouvement de vissage est un mouvement habituel pour un opérateur ayant l'habitude de réaliser des raccords électriques. En effet, nombre de raccords sont des raccords vissés. L'avantage ici par rapport à la plupart des raccords vissés, est qu'il est inutile de dénuder le fil à connecter avant de réaliser son raccordement.As shown in the first, second and third embodiments, such a connection device allows for a self-stripping connection by performing a screwing movement. This screwing movement is a usual movement for an operator who is used to making electrical connections. Indeed, many connections are screwed connections. The advantage over most screwed connections here is that there is no need to strip the wire to be connected before making the connection.

Les dispositifs décrits ci-dessus permettent de connecter des fils de divers diamètres. Il est possible dans un dispositif de connecter soit un fil de relativement grand diamètre ou bien deux fils de diamètre moindre. Pour les fils de diamètre moindre, il est important que l'embouchure de la fente de dénudage soit guidée en fin de raccordement pour garantir une pression mécanique suffisante entre les bords de la fente de dénudage et l'âme conductrice du fil connecté.The devices described above allow to connect wires of various diameters. It is possible in a device to connect either a wire of relatively large diameter or two wires of smaller diameter. For smaller diameter wires, it is important that the mouth of the slot of Stripping is guided at the end of the connection to ensure sufficient mechanical pressure between the edges of the stripping slot and the conductive core of the connected wire.

Comme il va de soi, l'invention ne se limite pas aux formes de réalisations décrites ci-dessus à titre d'exemples non limitatifs ; elle en embrasse au contraire toutes les variantes dans le cadre des revendications ci-après.As goes without saying, the invention is not limited to the embodiments described above as non-limiting examples; it encompasses all the variants in the context of the claims below.
