Definitions
- the invention relates to a connection piece with a slot stripping and / or retaining for connection arrangement for one or more several electrical wires.
- such an arrangement includes a slot stripping and / or retaining for at least one wire which is formed in a conductive piece of small thickness.
- One end of the slot is provided a flared mouthpiece intended to facilitate the longitudinal insertion of a wire, transversely to the slot where this wire is to be connected electrically and simultaneously ensuring, in most cases, a cross section of the insulation sheathing the wire.
- the soul of the thread, locally stripped by the mouth of the slot comes into contact with the edges of this slot which immobilizes it by pressure and which ensures continuity electrical connection between the core of the wire and the conductive part where the slot.
- the wire sheath is often wedged simultaneously between the edges a sheath wedge opening which extends in the vicinity and at the look of the retaining slot in an insulating box where the part is housed conductive.
- the known arrangements are generally calibrated for a range relatively limited wire core diameters for which a holding and connecting the wires by their souls reliably and with specific characteristics. It is therefore necessary to carry out a same layout model with slightly different dimensions to cover the range, known to those skilled in the art, of electrical wires for which it is possible to envisage a connection in this way.
- the size of the known connecting parts is relatively large. Indeed, the width of these pieces is at least equal to the diameter of the largest diameter wire that can be connected increased in width by the two side walls carrying the edges of the slot.
- document EP-A-0 511 098 describes a part of electrically conductive connection, for connection arrangement to stripping and / or retaining slot for one or more electrical wires, provided with at least one elongated, flared and through-opening slot one end, to allow transverse insertion of at least one wire electric between the edges of the slot which are arranged to retain the core conductor of this wire in position by jamming, said slot being defined by two of the edges of said piece which respectively terminate two first part elements, plans, curves or composite and converging towards said slot, extending on the same side of the part two seconds elements of this part which are themselves parallel and joined together the other by a connecting element located at one end of said second elements in a U-shaped arrangement.
- the present invention therefore aims to provide a part of electrically conductive connection, for connection arrangement to stripping and / or retaining slot for one or more electrical wires which has a small footprint.
- Another objective of the invention is to remedy all of the drawbacks that may exist in known techniques.
- the slot is defined by two of the edges of said piece which complete respectively the first two room elements, plans, curves or composite and convergent towards said slot.
- These first elements extend on the same side of the room two second elements of this part which are themselves parallel and joined to each other, according to a U-shaped arrangement, by a connecting element located at one of their ends.
- the connecting piece comprises teeth stripping which are respectively arranged on either side of a slit mouth and which correspond to a filling of the sub-assembly formed by a first element and / or by the second element which door.
- connection of a wire can be made to the stripping teeth level without the wire coming to take place between the second elements.
- the width of the connection piece can thus be decreased and we can come connect wires whose outside diameter is greater than the width of the room.
- the connecting element is located on one of the sides of the part which is adjacent to that where the slot extends.
- said connecting element is advantageously located on the other side of the workpiece with respect to the slot edges which form the slit mouths used for the introduction of wire (s).
- the connecting element is located on the opposite side of the room which is opposite to where the slot.
- the part according to the invention can have at least one slot, delimited by two edges each ending a first element, which itself has an insertion mouthpiece of wire with two stripped edges each provided on one edge different.
- a part according to the invention can be associated with a part identical to which it is connected by a common link strip to constitute a double connection piece.
- Connection piece 1 with stripping and retaining slot wire presented in Figures 1 to 7 is for example intended to be part a connection arrangement for electrical wires where this part is immobilized for example by embedding in a housing provided in a body of insulating material, not shown.
- this body is often made up of two parts additional molded insulating material, as provided in particular in document FR-A-2598039 also relating to an arrangement of connection for electric wires.
- connection piece 1 is for example produced by cutting, localized folding and thinning carried out by stamping on a flank in rigid conductive metal previously cut in a strip, such as than the one, also referenced 1, the cutting of which is presented in FIG. 8 and corresponds to the embodiment of Figures 1 and 2.
- This sidewall 1 is here symmetrical with respect to a transverse axis XX 'here located at the level of the middle part 2, here called element of connection, narrower than the rest of the flank which is intended to be an area junction on either side of which the two side portions 3A and 3B which border it are folded perpendicular to them at a level symbolized by the axes AA 'and BB' and in the same direction so as to delimit two large parallel faces, here called second elements of room.
- Said connecting element 2 is then located at one end of the second part elements with which it constitutes a U-shaped structure. The smaller width of the connecting element 2 relative to the rest of the sidewall is obtained by cutting a strip perpendicular to the axis transverse XX 'on one side of this side.
- Oblique folds or bends, converging when the connecting part 1 is formed, are made at the level of parts 4A and 4B located on either side of the transverse axis XX 'and beyond the connecting element to form two elements, called first elements of part, which will delimit the stripping and retaining slot of this part 1.
- These folds are made in a single operation at a symbolized level by an axis CC 'arranged on the edge of the connecting element 2 perpendicular to the transverse axis XX ', they give rise to first elements of planar, curved parts or possibly composites.
- the part is here assumed to be symmetrical with respect to a plane median on either side of which symmetrically extends the element of link. It then comprises at least two second elements folded down in the same direction on both sides of this connecting element which unites them so as to be parallel to the median plane of symmetry and the two first symmetrically projecting elements on the same side of the second elements which they extend obliquely to delimit the slot of stripping and / or restraint.
- edges of the first elements 4A, 4B which are intended to delimit a stripping and retaining slot 6 of the connecting piece 1 are prepared to constitute two parallel lips 5A, 5B.
- the lips 5A, 5B are prepared beforehand at the folds and while the side is still flat and the fold at the axis CC 'is produced before the two folds at the level of the axes AA' and BB '.
- the connecting element 2 is then located on one of the sides of the part which is adjacent to where the slit extends, on the other side of the workpiece lips 5A, 5B.
- connection piece when folded, has two elements pointed teeth 10A and 10B between which the slot is formed stripping and restraint 6.
- the latter presents, in terms of its mouth, converging banks 8E and 8F obtained by cutting oblique to the edges 5A and 5B of the flank which leads to a reduction in width of the teeth 10A, 10B, called stripping.
- the converging banks 8E, 8F are sharpened over at least part of their length to be able to ensure localized stripping of the core 7A of a wire 7 pushed between these strands relative to to which the wire is then at least approximately disposed transversely.
- the sheath 7B of the wire 7 is then crossed by the teeth 10A and 10B with which the core 7A of the wire comes into contact to be guided up between the wedging lips 5A, 5B of the slot which are at less initially parallel or almost parallel.
- This configuration has the effect of reducing the width of the connection piece by reducing the connecting element 2, since it eventually allows the wire sheath to overflow laterally on either side of the connection piece 1, as shown in Figures 1 and 6.
- the transverse size of the room is then likely to be less than the diameter of a wire sheathed electric provided to be connected to it. It is of course possible to make a double piece by combining two pieces 1 joined by example with alignment by a common bar 9 and oriented in the direction reverse, as already indicated above in relation to FIG. 6.
- connection piece 1 of this type receives a larger range of wire diameters than that expected with the workpiece connection described in document FR-A-2598039 already cited above. It is then necessary to leave a possibility of spacing at least one of the two second elements 3A, 3B at the free end of the minus this second element in the housing, not shown, of the body insulation where the connecting piece 1 is positioned.
- Connecting an electric wire to a connection piece 1 by immobilizing the core of this wire between the edges of the slot that comprises this part, supposedly housed in a housing made of insulating material, can be carried out using a hand tool or mounted on a machine.
- This tool is, for example, of the type described in the document FR-A-2584538.
- Another split is likely to be made in a wall of this housing opposite the slot 6 of a piece of connection 1 housed in this box. As known, this other slot ensures additional support of a wire by jamming the core of this wire by the edges of the slot 6.
- connection piece 1 such that mentioned above to a blocking push piece type, not shown, preventing a return of the wire to the mouth of the slot through which it was introduced, as long as the coin this type of blocking pusher has not been released and / or removed.
- Such a blocking pusher is likely to be constituted by a slide movable from the outside of the housing where the part of the connection 1 between a position for which it is possible to insert a wire, between a bearing end of the wire of said blocking pusher and the mouth of the slot 6 of this connection piece and, a position for which wire immobilization is ensured by cooperation of the edges of said slot 6 and by the locking pusher.
- connection piece according to the invention is shown in Figures 3 to 7.
- the same references are used subsequently to designate identical elements.
- edges of the first elements 4A, 4B which are intended to delimit the stripping tooth and retainer 6 of connection piece 1 are prepared to constitute two parallel lips 5A, 5B and in particular cut and thinned to form the banks 8A, 8B of a flared stripped mouth at one end of this slot.
- the edges 8A, 8B are prepared before folding and while the side is still flat.
- the folding element 2 is here located on the side of the part which is opposite to that where the slot extends.
- the mouth is produced by oblique cutting and stamping of the edges 8A, 8B beyond the lips parallels 5A, 5B at the respective ends of the first elements 4A and 4B at the free end of the teeth 10A, 10B.
- the mouth obtained allows to locally strip the core of a wire pushed in force at through this mouth by cutting the insulating protective sheath covering this soul.
- An electric wire 7 is shown wedged between the lips 5A and 5B of the slot 6 by its core 7A beyond the mouth which has allowed the guidance of this soul between these lips, after ensuring a local cutting of the sheath 7B by means of its edges 8A, 8B.
- Figure 3 shows a connection piece according to the invention in which are connected two electric wires 7 of small diameter.
- the wire 7 inserted first into the slot 6 is at the level of the second elements 3A, 3B and the second wire 7 takes place above the first wire, between the lips 5A, 5B, just below the edges 8A, 8B.
- Figures 4, 5 and 7 show the connection of an electric wire 7 whose diameter corresponds substantially to the width of the piece of connection.
- the wire 7 is stripped locally at the mouth by the edges 8A and 8B and comes to take place between the lips 5A and 5B.
- the sheath 7B then comes to rest on the upper free edges 11A, 11B of the second elements 3A, 3B located on the side of the teeth 10A, 10B.
- connection piece 1 As shown in Figure 6, it is also possible to come connect an electric wire 7 whose outside diameter is greater than the width of the connection piece 1.
- the sheath 7B of the wire then comes to rest on edges 11A and 11B while electrical contact is ensured at lip level 5A and 5B.
- the second elements 3A, 3B as well as the connecting piece 2 gives the connecting piece 1 the necessary elasticity to ensure a good electrical connection at the lips 5A, 5B.
- the shape of the slit and therefore the lips and edges, may be different from the shapes shown in the drawing and described above.

Description
L'invention concerne une pièce de connexion à fente de dénudage et/ou de retenue pour agencement de raccordement pour un ou plusieurs fils électriques.The invention relates to a connection piece with a slot stripping and / or retaining for connection arrangement for one or more several electrical wires.
Comme il est connu, de tels agencements sont notamment mis en oeuvre pour raccorder des fils électriques entre eux dans des organes spécialisés, tels que des blocs de fonction, ou pour raccorder des fils à des appareillages électriques.As is known, such arrangements are particularly put used to connect electrical wires together in organs specialized, such as function blocks, or for connecting wires to electrical equipment.
Typiquement, un tel agencement comporte une fente de dénudage et/ou de retenue pour au moins un fil qui est ménagée dans une pièce conductrice de faible épaisseur. Une extrémité de la fente est munie d'une embouchure évasée destinée à faciliter l'insertion longitudinale d'un fil, transversalement par rapport à la fente où ce fil doit venir se raccorder électriquement et à simultanément assurer, dans la plupart des cas, une coupe transversale de l'isolant gainant le fil. L'âme du fil, localement dénudée par l'embouchure de la fente, vient en contact avec les bords de cette fente qui l'immobilisent par pression et qui assurent une continuité électrique entre l'âme du fil et la pièce conductrice où est ménagée la fente. La gaine du fil est souvent coincée simultanément entre les bords d'une ouverture de coincement de gaine qui s'étend au voisinage et au regard de la fente de retenue dans un boítier isolant où est logée la pièce conductrice.Typically, such an arrangement includes a slot stripping and / or retaining for at least one wire which is formed in a conductive piece of small thickness. One end of the slot is provided a flared mouthpiece intended to facilitate the longitudinal insertion of a wire, transversely to the slot where this wire is to be connected electrically and simultaneously ensuring, in most cases, a cross section of the insulation sheathing the wire. The soul of the thread, locally stripped by the mouth of the slot, comes into contact with the edges of this slot which immobilizes it by pressure and which ensures continuity electrical connection between the core of the wire and the conductive part where the slot. The wire sheath is often wedged simultaneously between the edges a sheath wedge opening which extends in the vicinity and at the look of the retaining slot in an insulating box where the part is housed conductive.
Comme il est aussi connu, de par leur constitution, les agencements connus sont généralement calibrés pour une gamme relativement limitée de diamètres d'âme de fil pour laquelle est assuré un maintien et un raccordement des fils par leurs âmes de manière fiable et avec des caractéristiques déterminées. Il est donc nécessaire de réaliser un même modèle d'agencement avec des dimensions qui diffèrent légèrement pour couvrir la gamme, connue par l'homme du métier, de fils électriques pour lesquels il est possible d'envisager un raccordement de cette manière.As it is also known, by their constitution, the known arrangements are generally calibrated for a range relatively limited wire core diameters for which a holding and connecting the wires by their souls reliably and with specific characteristics. It is therefore necessary to carry out a same layout model with slightly different dimensions to cover the range, known to those skilled in the art, of electrical wires for which it is possible to envisage a connection in this way.
De plus, l'encombrement des pièces de connexion connues est relativement important. En effet, la largeur de ces pièces est au minimum égale au diamètre du fil de plus grand diamètre pouvant être raccordé augmenté de la largeur des deux parois latérales portant les bords de la fente.In addition, the size of the known connecting parts is relatively large. Indeed, the width of these pieces is at least equal to the diameter of the largest diameter wire that can be connected increased in width by the two side walls carrying the edges of the slot.
En outre, le document EP-A-0 511 098 décrit une pièce de connexion électriquement conductrice, pour agencement de connexion à fente de dénudage et/ou de retenue pour un ou plusieurs fils électriques, dotée au moins d'une fente de forme allongée, évasée et débouchante à une extrémité, pour permettre une insertion transversale d'au moins un fil électrique entre les bords de la fente qui sont disposés pour retenir l'âme conductrice de ce fil en position par coincement, ladite fente étant définie par deux des bords de ladite pièce qui terminent respectivement deux premiers éléments de pièce, plans, courbes ou composites et convergents vers ladite fente, prolongeant d'un même côté de la pièce deux seconds éléments de cette pièce qui sont eux-mêmes parallèles et réunis l'un à l'autre par un élément de liaison situé à un extrémité desdits seconds éléments selon une disposition en U. In addition, document EP-A-0 511 098 describes a part of electrically conductive connection, for connection arrangement to stripping and / or retaining slot for one or more electrical wires, provided with at least one elongated, flared and through-opening slot one end, to allow transverse insertion of at least one wire electric between the edges of the slot which are arranged to retain the core conductor of this wire in position by jamming, said slot being defined by two of the edges of said piece which respectively terminate two first part elements, plans, curves or composite and converging towards said slot, extending on the same side of the part two seconds elements of this part which are themselves parallel and joined together the other by a connecting element located at one end of said second elements in a U-shaped arrangement.
La présente invention a alors pour but de fournir une pièce de connexion électriquement conductrice, pour agencement de connexion à fente de dénudage et/ou de retenue pour un ou plusieurs fils électriques qui présente un encombrement réduit.The present invention therefore aims to provide a part of electrically conductive connection, for connection arrangement to stripping and / or retaining slot for one or more electrical wires which has a small footprint.
Un autre objectif de l'invention est de remédier à l'ensemble des inconvénients pouvant exister dans les techniques connues.Another objective of the invention is to remedy all of the drawbacks that may exist in known techniques.
La fente est définie par deux des bords de ladite pièce qui terminent respectivement deux premiers éléments de pièce, plans, courbes ou composites et convergents vers ladite fente. Ces premiers éléments prolongent d'un même côté de la pièce deux seconds éléments de cette pièce qui sont eux-mêmes parallèles et réunis l'un à l'autre, selon une disposition en U, par un élément de liaison situé à une de leurs extrémités.The slot is defined by two of the edges of said piece which complete respectively the first two room elements, plans, curves or composite and convergent towards said slot. These first elements extend on the same side of the room two second elements of this part which are themselves parallel and joined to each other, according to a U-shaped arrangement, by a connecting element located at one of their ends.
Selon l'invention, la pièce de connexion comporte des dents de dénudage qui sont respectivement disposées de part et d'autre d'une embouchure de fente et qui correspondent à un appointage du sous-ensemble formé par un premier élément et/ou par le second élément qui le porte.According to the invention, the connecting piece comprises teeth stripping which are respectively arranged on either side of a slit mouth and which correspond to a filling of the sub-assembly formed by a first element and / or by the second element which door.
Avec une telle pièce, la connexion d'un fil peut se faire au niveau des dents de dénudage sans que le fil vienne prendre place entre les seconds éléments. La largeur de la pièce de connexion peut ainsi être diminuée et on peut venir connecter des fils dont le diamètre extérieur est supérieur à la largeur de la pièce.With such a part, the connection of a wire can be made to the stripping teeth level without the wire coming to take place between the second elements. The width of the connection piece can thus be decreased and we can come connect wires whose outside diameter is greater than the width of the room.
Dans une forme de réalisation, l'élément de liaison est situé sur un des côtés de la pièce qui est adjacent à celui où s'étend la fente. Dans ce cas, ledit élément de liaison est avantageusement situé de l'autre côté de la pièce par rapport aux rives de fente qui forment la ou les embouchures de fente servant à l'introduction de fil(s).In one embodiment, the connecting element is located on one of the sides of the part which is adjacent to that where the slot extends. In in this case, said connecting element is advantageously located on the other side of the workpiece with respect to the slot edges which form the slit mouths used for the introduction of wire (s).
Dans une autre forme de réalisation, l'élément de liaison est situé sur le côté opposé de la pièce qui est opposé à celui où s'étend la fente.In another embodiment, the connecting element is located on the opposite side of the room which is opposite to where the slot.
Selon une forme d'exécution, la pièce selon l'invention peut comporter au moins une fente, délimitée par deux bords terminant chacun un premier élément, qui comporte elle-même, une embouchure d'insertion de fil dotée de deux rives dénudantes ménagées chacune sur un bord différent. According to one embodiment, the part according to the invention can have at least one slot, delimited by two edges each ending a first element, which itself has an insertion mouthpiece of wire with two stripped edges each provided on one edge different.
Une pièce selon l'invention peut être associée à une pièce identique à laquelle elle est raccordée par une barrette de liaison commune pour constituer une double pièce de connexion.A part according to the invention can be associated with a part identical to which it is connected by a common link strip to constitute a double connection piece.
L'invention, ses caractéristiques et ses avantages sont précisés
dans la description qui suit en liaison avec les figures évoquées ci-dessous.
La pièce de connexion 1 à fente de dénudage et de retenue de
fil présentée sur les figures 1 à 7 est par exemple destinée à faire partie
d'un agencement de raccordement pour fils électriques où cette pièce est
immobilisée par exemple par encastrement dans un logement ménagé dans
un corps en matériau isolant, non représenté. Comme il est connu en ce
domaine, ce corps est souvent constitué par emboítement de deux pièces
complémentaires en matériau isolant moulé, comme notamment prévu
dans le document FR-A-2598039 relatif lui aussi à un agencement de
raccordement pour fils électriques.
La pièce de connexion 1 est par exemple réalisée par découpe,
pliage et amincissement localisé réalisés par matriçage sur un flanc en
métal rigide bon conducteur préalablement découpé dans une bande, tel
que celui, aussi référencé 1, dont la découpe est présentée en figure 8 et
correspond à la forme de réalisation des figures 1 et 2.The
Ce flanc 1 est ici symétrique par rapport à un axe transversal
XX' ici situé au niveau de la partie médiane 2, ici dénommée élément de
liaison, plus étroite que le reste du flanc qui est destinée à être une zone
de jonction de part et d'autre de laquelle les deux portions de flanc 3A et
3B qui la bordent sont repliées perpendiculairement à elles à un niveau
symbolisé par les axes AA' et BB' et dans la même direction de manière à
délimiter deux grandes faces parallèles, ici dénommées seconds éléments
de pièce. Ledit élément de liaison 2 est alors situé à une extrémité des
seconds éléments de pièce avec lesquels il constitue une structure en U.
La largeur moindre de l'élément de liaison 2 par rapport au reste du flanc
est obtenue par découpe d'une bande perpendiculairement à l'axe
transversal XX' sur l'un des côtés de ce flanc.This
Des pliages ou cambrages obliques, convergents lorsque la
pièce de connexion 1 est formée, sont réalisés au niveau des parties 4A et
4B situées de part et d'autre de l'axe transversal XX' et au-delà de
l'élément de liaison pour former deux éléments, dits premiers éléments de
pièce, qui délimiteront la fente de dénudage et de retenue de cette pièce
1. Ces pliages sont réalisés en une même opération à un niveau symbolisé
par un axe CC' disposé en bordure de l'élément de liaison 2
perpendiculairement à l'axe transversal XX', ils donnent naissance à des
premiers éléments de pièces plans, courbes ou éventuellement
composites.Oblique folds or bends, converging when the
connecting
La pièce est ici supposée symétrique par rapport à un plan médian de part et d'autre duquel s'étend symétriquement l'élément de liaison. Elle comporte alors au moins deux seconds éléments rabattus dans une même direction de part et d'autre de cet élément de liaison qui les unit de manière à être parallèles au plan de symétrie médian et des deux premiers éléments symétriquement réalisés en saillie et du même côté des seconds éléments qu'ils prolongent obliquement pour délimiter la fente de dénudage et/ou de retenue.The part is here assumed to be symmetrical with respect to a plane median on either side of which symmetrically extends the element of link. It then comprises at least two second elements folded down in the same direction on both sides of this connecting element which unites them so as to be parallel to the median plane of symmetry and the two first symmetrically projecting elements on the same side of the second elements which they extend obliquely to delimit the slot of stripping and / or restraint.
Comme connu, les bords des premiers éléments 4A, 4B qui
sont destinés à délimiter une fente de dénudage et de retenue 6 de la
pièce de connexion 1 sont préparés pour constituer deux lèvres parallèles
5A, 5B.As known, the edges of the
Pratiquement, les lèvres 5A, 5B sont préparées préalablement
aux pliages et alors que le flanc est encore plan et le pliage au niveau de
l'axe CC' est réalisé avant les deux pliages au niveau des axes AA' et BB'.
L'élément de liaison 2 est alors situé sur un des côtés de la pièce qui est
adjacent à celui où s'étend la fente, de l'autre côté de la pièce par rapport
aux lèvres 5A, 5B.In practice, the
La pièce de connexion, une fois pliée, présente deux éléments
pointus en forme de dents 10A et 10B entre lesquels est ménagée la fente
de dénudage et de retenue 6. Cette dernière présente, au niveau de son
embouchure, des rives convergentes 8E et 8F obtenues par une découpe
en oblique des bords 5A et 5B du flanc qui conduit à une réduction en
largeur des dents 10A, 10B, dites de dénudage.The connection piece, when folded, has two elements
pointed
Dans l'exemple envisagé, les rives convergentes 8E, 8F sont
aiguisées sur au moins une partie de leur longueur pour pouvoir assurer un
dénudage localisé de l'âme 7A d'un fil 7 poussé entre ces rives par rapport
auquel le fil est alors au moins approximativement disposé
transversalement. La gaine 7B du fil 7 est alors traversée par les dents
10A et 10B avec lesquelles l'âme 7A du fil vient en contact pour être
guidé jusqu'entre les lèvres de coincement 5A, 5B de la fente qui sont au
moins initialement parallèles ou quasi-parallèles.In the example envisaged, the converging
Cette configuration a pour effet de permettre de réduire la
largeur de la pièce de connexion par réduction de l'élément de liaison 2,
puisqu'elle permet éventuellement de laisser la gaine du fil déborder
latéralement de part et d'autre de la pièce de connexion 1, comme montré
sur les figures 1 et 6.This configuration has the effect of reducing the
width of the connection piece by reducing the connecting element 2,
since it eventually allows the wire sheath to overflow
laterally on either side of the
L'encombrement transversal de la pièce, au moins au niveau de
deux dents de dénudage disposées de part et d'autre d'une embouchure
de fente, est alors susceptible d'être inférieur au diamètre d'un fil
électrique gainé prévue pour y être raccordé. Il est bien entendu possible
de réaliser une pièce double par association de deux pièces 1 réunies par
exemple à l'alignement par une barrette commune 9 et orientée en sens
inverse, comme déjà indiqué plus haut en relation avec la figure 6.The transverse size of the room, at least at the level of
two stripping teeth arranged on either side of a mouth
slit, is then likely to be less than the diameter of a wire
sheathed electric provided to be connected to it. It is of course possible
to make a double piece by combining two
L'insertion d'une âme 7A d'un fil électrique 7 entre les lèvres
5A, 5B tend à ouvrir la pièce de connexion en écartant les seconds
éléments 3A, 3B l'un de l'autre au niveau des extrémités libres respectives
de ces seconds éléments qui sont à l'opposé de l'élément de liaison 2. Il
est donc possible à une pièce de connexion 1 de ce type de recevoir une
gamme de diamètres de fils plus importante que celle prévue avec la pièce
de connexion décrite dans le document FR-A-2598039 déjà cité plus haut.
Il est alors nécessaire de laisser une possibilité d'écartement à au moins
l'un des deux seconds éléments 3A, 3B au niveau de l'extrémité libre d'au
moins ce second élément dans le logement non représenté du corps
isolant où est positionnée la pièce de connexion 1. The insertion of a

par immobilisation de l'âme de ce fil entre les bords de la fente que
comporte cette pièce, supposée logée dans un boítier en matériau isolant,
est susceptible d'être réalisé à l'aide d'un outil manuel ou monté sur une
machine. Cet outil est par exemple du type de celui décrit dans le
document FR-A-2584538. Une autre fente est susceptible d'être réalisée
dans une paroi de ce boítier en regard de la fente 6 d'une pièce de
connexion 1 logée dans ce boítier. Comme connu, cette autre fente assure
un maintien supplémentaire d'un fil par coincement de l'âme de ce fil par

connexion 1 entre une position pour laquelle il est possible d'insérer un fil,
entre une extrémité d'appui du fil dudit poussoir bloquant et l'embouchure
de la fente 6 de cette pièce de connexion et, une position pour laquelle
une immobilisation de fil est assurée par coopération des bords de ladite
fente 6 et par le poussoir bloquant.Such a blocking pusher is likely to be constituted by a
slide movable from the outside of the housing where the part of the
Une autre forme de réalisation d'une pièce de connexion selon l'invention est représentée sur les figures 3 à 7. Les mêmes références sont utilisées par la suite pour désigner des éléments identiques.Another embodiment of a connection piece according to the invention is shown in Figures 3 to 7. The same references are used subsequently to designate identical elements.
Dans cette forme de réalisation, les bords des premiers
éléments 4A, 4B qui sont destinés à délimiter le dente de dénudage et de
retenue 6 de la pièce de connexion 1 sont préparés pour constituer deux
lèvres parallèles 5A, 5B et notamment découpés et amincis pour former les
rives 8A, 8B d'une embouchure dénudante évasée à une extrémité de
cette fente.In this embodiment, the edges of the
Les rives 8A, 8B sont préparées préalablement aux pliages et
alors que le flanc est encore plan. L'élément de pliage 2 est ici situé sur le
côté de la pièce qui est opposé à celui où s'étend la fente.The
Dans la réalisation présentée, l'embouchure est réalisée par
découpe oblique et estampage des rives 8A, 8B au-delà des lèvres
parallèles 5A, 5B au niveau des extrémités respectives des premiers
éléments 4A et 4B à l'extrémité libre des dents 10A, 10B. L'embouchure
obtenue permet de dénuder localement l'âme d'un fil poussé en force au
travers de cette embouchure en découpant la gaine isolante de protection
recouvrant cette âme. Un fil électrique 7 est montré coincé entre les lèvres
5A et 5B de la fente 6 par son âme 7A au-delà de l'embouchure qui a
permis le guidage de cette âme entre ces lèvres, après avoir assuré une
découpe locale de la gaine 7B par l'intermédiaire de ses rives 8A, 8B.In the embodiment presented, the mouth is produced by
oblique cutting and stamping of the

dans laquelle sont connectés deux fils électriques 7 de faible diamètre. Le
fil 7 introduit en premier dans la fente 6 se trouve au niveau des seconds
éléments 3A, 3B et le second fil 7 prend place au-dessus du premier fil,
entre les lèvres 5A, 5B, juste en dessous des rives 8A, 8B.Figure 3 shows a connection piece according to the invention
in which are connected two
Les figures 4, 5 et 7 montrent la connexion d'un fil électrique 7
dont le diamètre correspond sensiblement à la largeur de la pièce de
connexion. Le fil 7 est dénudé localement au niveau de l'embouchure par
les rives 8A et 8B et vient prendre place entre les lèvres 5A et 5B. La
gaine 7B vient alors reposer sur les bords libres supérieurs 11A, 11B des
seconds éléments 3A, 3B se trouvant du côté des dents 10A, 10B.Figures 4, 5 and 7 show the connection of an
Comme représenté sur la figure 6, il est aussi possible de venir
connecter un fil électrique 7 dont le diamètre extérieur est supérieur à la
largeur de la pièce de connexion 1. La gaine 7B du fil vient alors reposer
sur les bords 11A et 11B tandis que le contact électrique est assuré au
niveau des lèvres 5A et 5B. Les seconds éléments 3A, 3B ainsi que la
pièce de liaison 2 donnent à la pièce de connexion 1 l'élasticité nécessaire
pour assurer une bonne connexion électrique au niveau des lèvres 5A, 5B.As shown in Figure 6, it is also possible to come

Comme il va de soi, l'invention ne se limite pas aux deux formes de réalisation décrites ci-dessus à titre d'exemples non limitatifs ; elle en embrasse au contraire toutes les variantes dans le cadre des revendications ci-après.It goes without saying that the invention is not limited to both embodiments described above by way of nonlimiting examples; on the contrary, it embraces all variants within the framework of claims below.
Ainsi par exemple, la forme de la fente, et donc des lèvres et des rives, peut être différente des formes représentées au dessin et décrites ci-dessus.So for example, the shape of the slit, and therefore the lips and edges, may be different from the shapes shown in the drawing and described above.
