Ce type de clips de mise à la terre est couramment utilisé pour mettre à la terre tout type d'équipement électrique, notamment des panneaux à énergie solaire. En effet, la réglementation en vigueur impose, notamment en France, que chaque panneau à énergie solaire soit raccordé à la terre par un fil de terre. Ce raccordement doit être durable et facile à installer. On utilise donc des clips de mise à la terre spécifiques formés par exemple d'une plaque métallique à laquelle un fil de terre est raccordé. La plaque définit généralement une fente apte à être engagée sur un bord métallique du panneau à énergie solaire pour mettre en liaison électrique le fil de terre et le bord du panneau à énergie solaire. Lors du raccordement, le fil de terre doit être dénudé pour que son âme de cuivre puisse être en contact électrique simultanément avec le bord métallique et avec le clip de mise à la terre. Ce dénudage doit être réalisé de manière soignée afin de sectionner la gaine plastique sans ôter le cuivre du fil de terre sous peine de modifier de manière non négligeable les caractéristiques techniques de ce fil de terre et de nuire à l'efficacité de la mise à la terre. De plus, il est préférable que le bord métallique du panneau à énergie solaire soit rayé pour assurer un meilleur contact électrique entre le bord métallique et le clip de mise à la terre. Ce type de clips de mise à la terre peut être utilisé pour d'autres applications similaires telles que par exemple la mise à la terre des câbles téléphoniques des abonnés lors du câblage de centraux téléphoniques. La publication US 6 106 310 divulgue le préambule de la revendication indépendante 1. La publication FR 2 694 141 décrit un clip de mise à la terre formé d'un plaque métallique monobloc courbée en S de manière à définir deux fentes élastiquement déformables orientées à l'opposé l'une de l'autre et séparées par une paroi. Une fente est destinée à être engagée sur un support métallique, l'autre à recevoir le fil de terre. Pour éviter l'opération de dénudage, les parois de ce clip de mise à la terre comporte des découpes pliées vers l'intérieur de chaque fente afin d'y faire saillie et de former des couteaux aptes à couper la gaine isolante du fil de terre sur une profondeur adéquate pour garantir le contact électrique entre le fil de terre et le clip de mise à la terre. De part l'orientation des fentes, une fois le clip de mise à la terre installé avec le fil de terre sur le support métallique, le fil de terre s'étend dans un plan sensiblement parallèle au bord du support métallique. Cette disposition du fil de terre est souvent peu pratique car, pour l'installation du fil de terre, une orientation perpendiculaire au bord du panneau à énergie solaire est souvent préférée. Par ailleurs, avec ce clip de mise à la terre, le fil de terre n'est pas sécurisé de manière fiable sur le clip de mise à la terre duquel il peut être désolidarisé par inadvertance.This type of grounding clip is commonly used to ground any type of electrical equipment, including solar panels.

The publication US 6,106,310 discloses the preamble of the independent claim 1. The publication FR 2,694,141 discloses a grounding clip formed of a one-piece metal plate curved in S so as to define two elastically deformable slots oriented away from one another and separated by a wall. A slot is intended to be engaged on a metal support, the other to receive the ground wire. To avoid the stripping operation, the walls of this earthing clip have cutouts folded towards the inside of each slot in order to protrude therefrom and to form knives capable of cutting the insulating sheath of the earth wire. to an adequate depth to ensure electrical contact between the ground wire and the grounding clip. Due to the orientation of the slots, once the grounding clip is installed with the ground wire on the metal support, the ground wire extends in a plane substantially parallel to the edge of the metal support. This arrangement of the ground wire is often impractical because, for the installation of the ground wire, an orientation perpendicular to the edge of the solar panel is often preferred. Furthermore, with this earthing clip, the ground wire is not reliably secured to the earthing clip from which it can be inadvertently disconnected.

La publication US 6,106,310 décrit un clip de mise à la terre formé d'une plaque métallique monobloc comportant notamment des pattes déformables aptes à enserrer le fil de terre pour garantir son maintien. Ce clip de mise à la terre comporte une paroi et deux ailes recourbées élastiquement déformables, définissant avec la paroi, deux fentes aptes à être engagées sur un support métallique. Les ailes sont par ailleurs pourvues de découpes déformées vers l'intérieur des fentes afin de favoriser l'accrochage du clip de mise à la terre sur le support et de garantir le contact électrique. Les pattes déformables sont orientées perpendiculairement à l'ouverture des fentes et permettent ainsi que le fil de terre, une fois le clip de mise à la terre installé, s'étende perpendiculairement au bord du support métallique dans un plan sensiblement confondu. Toutefois, cette construction est encombrante et les pattes déformables dépassent de manière importante du support métallique après l'installation du clip de mise à la terre. De plus, avant d'enserrer le fil de terre avec les pattes déformables, il convient de le dénuder ce qui nécessite une opération supplémentaire qui doit être répétée pour chaque fil de terre.The publication US 6,106,310 discloses a grounding clip formed of a one-piece metal plate including deformable tabs adapted to grip the ground wire to ensure its maintenance. This earthing clip comprises a wall and two bent elastically deformable wings, defining with the wall, two slots adapted to be engaged on a metal support. The wings are also provided with deformed cuts towards the inside of the slots in order to promote the attachment of the earthing clip on the support and to guarantee the electrical contact. The deformable tabs are oriented perpendicular to the opening of the slots and thus allow the ground wire, once the clip of installed ground, extends perpendicular to the edge of the metal support in a substantially merged plane. However, this construction is bulky and the deformable tabs significantly exceed the metal support after installation of the earthing clip. In addition, before clamping the ground wire with deformable tabs, it should be stripped which requires an additional operation that must be repeated for each ground wire.

La publication US 3,528,050 décrit un clip de mise à la terre formé d'une plaque métallique monobloc en forme en U élastiquement déformable définissant une fente apte à être engagée sur un support métallique. Les extrémités libres de la fente sont évasées pour faciliter cet engagement. La paroi de la plaque métallique comporte une découpe déformée vers l'intérieur de la fente afin de favoriser l'accrochage du clip de mise à la terre sur le support et de garantir le contact électrique. La plaque métallique est par ailleurs traversée par deux orifices au travers desquels un fil de terre peut circuler de manière à ce qu'une portion de ce fil de terre soit située dans la fente et plaqué par la forme en U contre le support métallique une fois le clip de mise à la terre installé. Les orifices sont alignés perpendiculairement à l'ouverture de la fente. Ainsi, une fois le clip installé, le fil de terre s'étend perpendiculairement au bord du support métallique. Afin de garantir le contact électrique entre le fil de terre et le clip de mise à la terre, le fil de terre doit être dénudé avant son insertion dans les orifices.The publication US 3,528,050 discloses a grounding clip formed of a one-piece metal plate shaped elastically deformable U defining a slot adapted to be engaged on a metal support. The free ends of the slot are flared to facilitate this engagement. The wall of the metal plate has a deformed cut towards the inside of the slot in order to promote the attachment of the earthing clip on the support and to guarantee the electrical contact. The metal plate is also traversed by two orifices through which a ground wire can flow so that a portion of the earth wire is located in the slot and plated by the U-shape against the metal support once. the grounding clip installed. The orifices are aligned perpendicular to the opening of the slot. Thus, once the clip installed, the ground wire extends perpendicular to the edge of the metal support. To ensure electrical contact between the ground wire and the grounding clip, the ground wire must be stripped before insertion into the holes.

La publication US 4,456,321 décrit un clip de mise à la terre formé d'une plaque métalliques et d'un élément de blocage. La plaque a une forme en U élastiquement déformable définissant une première fente apte à être engagée sur le support métallique. La base de la forme en U comporte une seconde fente à bords parallèles orientée perpendiculairement à la première fente et apte à recevoir le fil de terre de sorte que ce que ce dernier soit dans un plan perpendiculaire à celui de l'ouverture de la première fente. La seconde fente de la plaque débouche ainsi à l'opposé de la première fente. La plaque comporte des découpes déformée vers l'intérieur de la fente dont des découpes favorisant l'accrochage du clip de mise à la terre et le contact électrique, et d'autres découpes délimitant des butées limitant la profondeur de l'engagement de la plaque sur le support. L'élément de blocage a également une forme en U définissant une troisième fente apte à être engagée par-dessus la plaque. La paroi externe de la plaque et la paroi interne de l'élément de blocage comportent des formes complémentaires aptes à s'engager mutuellement lorsque l'élément de blocage est engagé sur la plaque. L'élément de blocage comporte en outre une quatrième fente à bords parallèles orientée perpendiculairement à la troisième fente et apte à recevoir le fil de terre de sorte que ce que ce dernier soit dans un plan perpendiculaire à celui de l'ouverture de la troisième fente. Pour la mise en place de ce clip de mise à la terre, dans un premier temps la plaque est engagée sur le bord du support métallique, puis dans un second temps, le fil de terre est placé dans la seconde fente puis dans un troisième temps, l'élément de blocage est engagé sur la plaque, les seconde et quatrième fentes bloquant ainsi le fil de terre. Les bords parallèles des seconde et quatrième fentes sont prévues coupantes afin de sectionner la gaine du fil de terre et d'assurer le contact électrique avec l'âme en cuivre. Ce clip de mise à la terre étant réalisé en deux pièces, il est peu pratique à utiliser et présente un risque supplémentaire de désolidarisation de l'élément de blocage par rapport à la plaque.The publication US 4,456,321 discloses an earthing clip formed of a metal plate and a locking element. The plate has an elastically deformable U shape defining a first slot adapted to be engaged on the metal support. The base of the U-shape has a second slot with parallel edges oriented perpendicular to the first slot and adapted to receive the ground wire so that the latter is in a plane perpendicular to that of the opening of the first slot . The second slot of the plate thus opens opposite the first slot. The plate has deformed cuts towards the inside of the slot including cutouts promoting the attachment of the earthing clip and the contact electrical, and other cutouts defining stops limiting the depth of engagement of the plate on the support. The locking element also has a U shape defining a third slot adapted to be engaged over the plate. The outer wall of the plate and the inner wall of the locking element comprise complementary shapes able to engage one another when the locking element is engaged on the plate. The locking element further comprises a fourth slot with parallel edges oriented perpendicular to the third slot and adapted to receive the earth wire so that the latter is in a plane perpendicular to that of the opening of the third slot . For the installation of this earthing clip, at first the plate is engaged on the edge of the metal support, then in a second step, the ground wire is placed in the second slot and then in a third time , the locking element is engaged on the plate, the second and fourth slots thus blocking the ground wire. The parallel edges of the second and fourth slots are cut to sever the sheath of the ground wire and to provide electrical contact with the copper core. This earthing clip being made in two parts, it is impractical to use and has an additional risk of separation of the locking element relative to the plate.

La publication US 5,451,167 décrit un clip de mise à la terre formé d'une plaque métallique monobloc en forme en T dont la tige principale est recourbée sous la partie centrale de la forme en T afin de former une première fente élastiquement déformable apte à être engagée sur un support métallique. La partie centrale de la forme en T et la tige principale sont pourvues de découpes déformées vers l'intérieur de la fente pour favoriser l'accrochage du clip de mise à la terre et garantir le contact électrique. Les branches latérales de la forme en T sont relevées selon une forme en U au-dessus de la partie centrale, à l'opposé de première fente. Les branches latérales comportent chacune une seconde fente orientée dans un plan perpendiculaire à l'ouverture de la première fente et débouchant à l'opposé de la partie centrale. Ces secondes fentes sont de largeur inférieure à l'âme en cuivre du fil de masse et leurs bords sont prévus coupants pour sectionner la gaine plastique. Chaque fente comporte une portion élargie apte à recevoir l'âme du fil de terre après sectionnement de la gaine plastique. Les secondes fentes ayant une largeur inférieure à l'âme du fil de terre, cette dernière risque d'être endommagée par les bords coupants des secondes fentes lors de la mise en place du fil de terre. De plus, la forme en U dépasse fortement de la fente d'engagement du support. Ce clip de mise à la terre est donc encombrant. Par ailleurs, la mise en place du fil de terre est rendue difficile par la nécessité de l'introduire dans les deux secondes fentes des ailes de la forme en U. De plus, la portion de fil de terre située entre les ailes de la forme en U est inutilisée ce qui représente un surcoût en fil de terre. Enfin, si par inadvertance on sollicite cette portion de fil de terre, on risque de dégager le fil de terre de l'une ou des deux secondes fentes et d'interrompre le contact électrique. Ce clip de mise à la terre ne permet donc pas un contact électrique fiable.The publication US5,451,167 discloses a grounding clip formed of a T-shaped one-piece metal plate whose main stem is bent under the central portion of the T-shaped to form a first elastically deformable slot adapted to be engaged on a metal support . The central part of the T-shape and the main stem are provided with deformed cut-outs towards the inside of the slot to promote attachment of the earthing clip and to guarantee electrical contact. The lateral branches of the T-shape are raised in a U-shape above the central part, opposite the first slot. The lateral branches each comprise a second slot oriented in a plane perpendicular to the opening of the first slot and opening away from the central portion. These second slots are of less width than the soul in copper of the ground wire and their edges are provided sharp to cut the plastic sheath. Each slot has an enlarged portion adapted to receive the core of the earth wire after cutting the plastic sheath. The second slots having a width less than the core of the ground wire, the latter may be damaged by the sharp edges of the second slots when placing the ground wire. In addition, the U-shape greatly exceeds the support engagement slot. This earthing clip is therefore bulky. In addition, the introduction of the ground wire is made difficult by the need to introduce it into the second two slots of the wings of the U-shape. In addition, the portion of ground wire located between the wings of the form U-shaped is unused which represents an extra cost in ground wire. Finally, if inadvertently it solicits this portion of ground wire, it is possible to disengage the ground wire of the one or two second slots and interrupt the electrical contact. This earthing clip does not allow reliable electrical contact.

Description des modes de réalisationDescription of the embodiments

Le clip de mise à la terre selon l'invention est utilisé pour fixer un fil de terre sur un support et raccorder électriquement ce support à la terre. En référence à la figure 2, le fil de terre 10 utilisé comporte une âme conductrice 11, de manière générale en cuivre, recouverte par une gaine isolante 12, de manière générale en plastique. L'âme conductrice 11 peut être une âme pleine formée d'un fil unique ou une âme tressée formée d'une pluralité de filaments. Une extrémité du fil de terre 10 est raccordée au clip de mise à la terre décrit plus loin, l'autre extrémité (non représentée) est raccordée à la terre de manière connue. Le support est par exemple un panneau à énergie solaire ou tout autre support adapté présentant un bord, de préférence sensiblement plan et de quelques millimètres d'épaisseur, pouvant être engagé dans une fente.The earthing clip according to the invention is used to fix a ground wire on a support and electrically connect the support to the ground. With reference to the figure 2 , the ground wire 10 used comprises a conductive core 11, generally copper, covered by an insulating sheath 12, generally made of plastic. The conductive core 11 may be a solid core formed of a single wire or a braided core formed of a plurality of filaments. One end of the ground wire 10 is connected to the earthing clip described later, the other end (not shown) is grounded in a known manner. The support is for example a solar energy panel or any other suitable support having an edge, preferably substantially flat and a few millimeters thick, which can be engaged in a slot.

En référence principalement aux figures 1, 4, 5 et 6, le clip de mise à la terre 1 selon l'invention est formé d'une plaque métallique monobloc pliée de manière à présenter une forme en U définie par une "première" et une "seconde" ailes 2, 3 reliées entre elles par une base 4. La plaque métallique est élastiquement déformable au niveau des première et deuxième lignes de pliages longitudinales L1, L2 reliant les première" et "seconde" ailes 2, 3 et la base 4. Ces première et deuxième lignes de pliage longitudinales L1, L2 ainsi que les autres lignes de pliage longitudinales décrites plus loin sont représentées sur la figure 4 par des traits mixtes fins à deux points. Les "première" et "seconde" ailes 2, 3 peuvent donc être élastiquement rapprochées ou éloignées l'une de l'autre. Dans cet état déformé, les "première" et "seconde" ailes 2, 3 tendent à revenir dans leur position non déformée. Les "première" et "seconde" ailes 2, 3 définissent, avec la base 4, une fente longitudinale 5 destinée à recevoir le bord du support 100 (représenté sur les figures 2 et 3). Cette fente longitudinale 5 est traversée par une fente transversale 6 destinée à recevoir le fil de terre 10 prévue dans les "première" et "seconde" ailes 2, 3, sensiblement perpendiculaire à la fente longitudinale 5 et débouchant du même coté du clip de mise à la terre 1 que la fente longitudinale 5.With reference mainly to figures 1 , 4, 5 and 6 , the earthing clip 1 according to the invention is formed of a one-piece metal plate folded so as to have a U-shaped shape defined by a "first" and a "second" wings 2, 3 interconnected by a base 4. The metal plate is elastically deformable at the first and second longitudinal fold lines L1, L2 connecting the first "and" second "wings 2, 3 and the base 4. These first and second longitudinal fold lines L1, L2 as well as the other longitudinal fold lines described below are represented on the figure 4 by mixed fine lines at two points. The "first" and "second" wings 2, 3 can therefore be elastically close to or distant from each other. In this deformed state, the "first" and "second" wings 2, 3 tend to return to their undeformed position. The "first" and "second" wings 2, 3 define, with the base 4, a longitudinal slot 5 intended to receive the edge of the support 100 (shown in FIGS. Figures 2 and 3 ). This longitudinal slot 5 is traversed by a transverse slot 6 intended to receive the earth wire 10 provided in the "first" and "second" wings 2, 3, substantially perpendicular to the longitudinal slot 5 and opening on the same side of the setting clip. to the earth 1 that the longitudinal slot 5.

La "première" aile 2 comporte deux "premières" découpes 20 réparties de part et d'autre de la fente transversale 6. Dans cet exemple, les "premières" découpes 20 forment un V à angle droit dont une "première" branche s'étend sensiblement perpendiculairement du bord externe correspondant de la "première" aile 2 vers la fente transversale 6, et dont la "seconde" branche s'étend sensiblement parallèlement à la fente transversale 6. Les "premières" découpes 20 peuvent également avoir toute autre forme adaptée. Chaque "première" découpe 20 délimite ainsi un "premier" volet 21 plié, par rapport à une troisième ligne de pliage longitudinale L3, vers l'intérieur de la fente longitudinale 5. Chaque "premier" volet 21 définit ainsi, avec la "première" aile 2, un premier angle α (visible sur les figures 1 et 5) par exemple de 5 à 15°. Ce premier angle α est faible et facilite l'introduction du support 100 dans la fente longitudinale 5. De plus, par effet d'arc-boutement, le premier angle α permet de résister à toute tentative de retrait du support 100 de cette même fente longitudinale 5. Selon le mode de réalisation représenté, ces "premières" découpes 20 sont réalisées avec retrait de matière, c'est-à-dire que, lorsque la plaque métallique est présentée à plat (voir la figure 4), il existe un espace entre le bord de chaque "premier" volet 21 et le reste de la plaque métallique. Cet espace permet d'augmenter la flexibilité de chaque "premier" volet 21 dont l'extrémité libre est destinée à venir en contact avec le support 100 afin de favoriser le maintien du clip de mise à la terre 1 sur le support 100 et le contact électrique entre le clip de mise à la terre 1 et le support 100. Dans cet exemple, l'extrémité libre de chaque "premier" volet 21 est rectiligne. Cette extrémité libre peut également être prévue avec une ou plusieurs pointes, par exemple reliées entre elles par un arc de cercle, ces pointes favorisant encore d'avantage le maintien et le contact électrique. La "première" aile 2 comporte également deux "troisièmes" découpes 22 réparties de part et d'autre de la fente transversale 6, sensiblement similaires aux "premières" découpes 20 et prévues décalée vers la base 4 de la forme en U par rapport aux "premières" découpes 20. Les "troisièmes" découpes 22 peuvent également avoir toute autre forme adaptée. Les "troisièmes" découpes 22 forment des "troisièmes" volets 23 et se différencient des "premières" découpes 20 principalement par le fait que ces "troisièmes" volets 23 sont pliés, autour d'une quatrième ligne de pliage longitudinale L4, vers l'intérieur de la fente longitudinale 5, selon un second angle ε (visible sur la figure 5) d'environ 90° par rapport à la "première" aile 2. Les "troisièmes" volets 23 définissent ainsi, avant le fond de la fente longitudinale 5, une butée apte à recevoir l'appui du support 100 qui ne risque ainsi pas de venir écraser le fil de terre 10 au risque de l'endommager. Les "troisièmes" découpes 22 se différencient également des "premières" découpes 20 par le fait que ces "troisièmes" découpes 22 sont réalisées sans retrait de matière, c'est-à-dire que, lorsque la plaque métallique est présentée à plat (voir la figure 4), il n'existe que l'espace de chaque "troisième" découpe 22 entre le bord du "troisième" volet 23 et le reste de la plaque métallique.The "first" wing 2 comprises two "first" cutouts 20 distributed on either side of the transverse slot 6. In this example, the "first" cutouts 20 form a right angle V of which a "first" branch extends substantially perpendicularly from the corresponding outer edge of the "first" wing 2 to the transverse slot 6, and whose "second" leg extends substantially parallel to the transverse slot 6. The "first" cutouts 20 may also have any other shape adapted. Each "first" cut 20 thus delimits a "first" flap 21 bent, with respect to a third longitudinal fold line L3, towards the inside of the longitudinal slot 5. Each "first" flap 21 thus defines, with the "first""wing 2, a first angle α (visible on the figures 1 and 5 ) for example from 5 to 15 °. This first angle α is small and facilitates the introduction of the support 100 in the longitudinal slot 5. In addition, by bracing effect, the first angle α makes it possible to resist any attempt to remove the support 100 from this same slot 5. According to the embodiment shown, these "first" cutouts 20 are made with removal of material, that is to say that, when the metal plate is presented flat (see figure 4 ), there is a gap between the edge of each "first" flap 21 and the remainder of the metal plate. This space makes it possible to increase the flexibility of each "first" shutter 21 whose free end is intended to come into contact with the support 100 in order to favor the retention of the earthing clip 1 on the support 100 and the contact between the earthing clip 1 and the support 100. In this example, the free end of each "first" flap 21 is rectilinear. This free end may also be provided with one or more points, for example interconnected by a circular arc, these spikes further promoting the maintenance and the electrical contact. The "first" wing 2 also comprises two "third" cutouts 22 distributed on either side of the transverse slot 6, substantially similar to the "first" cutouts 20 and provided offset to the base 4 of the shape in U with respect to the "first" cutouts 20. The "third" cutouts 22 may also have any other suitable shape. The "third" cutouts 22 form "third" flaps 23 and are different from the "first" cut-outs 20 mainly by the fact that these "third" flaps 23 are folded around a fourth longitudinal fold line L4 towards the inside the longitudinal slot 5, according to a second angle ε (visible on the figure 5 ) the "third" flaps 23 thus define, before the bottom of the longitudinal slot 5, a stop adapted to receive the support of the support 100 which does not risk so to crush the ground wire 10 at the risk of damaging it. The "third" cutouts 22 are also different from the "first" cut-outs 20 by the fact that these "third" cut-outs 22 are made without removal of material, that is to say that, when the metal plate is presented flat ( see it figure 4 ), there is only the space of each "third" cutout 22 between the edge of the "third" flap 23 and the rest of the metal plate.

La "seconde" aile 3 comporte deux "secondes" découpes 30 réparties de part et d'autre de la fente transversale 6 et sensiblement similaires aux "premières" découpes 20. Les "secondes" découpes 30 peuvent également avoir toute autre forme adaptée telle que notamment une forme en pointe illustrée par la figure 3. Les "secondes" découpes 30 sont prévues entre les "premières" et "troisième" découpes 20, 22. Elles forment des "seconds" volets 31 qui sont pliés, avec les extrémités libres de la "seconde" aile 3, autour d'une cinquième ligne de pliage longitudinale L5, vers l'intérieur de la fente longitudinale 5, d'un troisième angle β (visible sur les figures 1 et 5) par exemple de 20 à 40°. Les extrémités libres 32 de la "seconde" aile 3 sont ainsi dans le prolongement direct du "second" volet 31. La ligne de pliage longitudinale 33 s'étend sensiblement parallèlement au fond de la forme en U, en partant de l'extrémité de chaque "seconde" découpe 30 jusqu'au bord opposé de la "seconde" aile 3. Ainsi, l'extrémité libre 32 de la "seconde" aile 3 est pliée vers l'extérieur de la fente longitudinale 5 et les "seconds" volets 31 sont pliés vers l'intérieur de la fente longitudinale 5. Les "secondes" découpes 30 se différencient des "premières" découpes 20 par le fait que ces "secondes" découpes 30 sont réalisées sans retrait de matière, c'est-à-dire que, lorsque la plaque métallique est présentée à plat (voir la figure 4), il n'existe que l'espace de chaque "seconde" découpe 30 entre le bord du "second" volet 31 et le reste de la plaque métallique. Cette construction favorise la rigidité des "seconds" volets 31. Ainsi, lorsque le "second" volet 31 est sollicité, c'est toute la "seconde" aile 3 qui fléchit à partir de la base de la forme en U.The "second" wing 3 comprises two "second" cutouts 30 distributed on either side of the transverse slot 6 and substantially similar to the "first" cutouts 20. The "second" cutouts 30 may also have any other suitable shape such that particularly a pointed form illustrated by the figure 3 . The "second" cutouts 30 are provided between the "first" and "third" cutouts 20, 22. They form "second" flaps 31 which are folded, with the free ends of the "second" flange 3, around a fifth longitudinal fold line L5, towards the inside of the longitudinal slot 5, with a third angle β (visible on the figures 1 and 5 ) for example from 20 to 40 °. The free ends 32 of the "second" wing 3 are thus in the direct extension of the "second" flap 31. The longitudinal fold line 33 extends substantially parallel to the bottom of the U-shape, starting from the end of each "second" cut 30 to the opposite edge of the "second" wing 3. Thus, the free end 32 of the "second" wing 3 is folded outwardly of the longitudinal slot 5 and the "second" flaps 31 are folded towards the inside of the longitudinal slot 5. The "second" cutouts 30 are different from the "first" cutouts 20 by the fact that these "second" cuts 30 are made without removal of material, that is, that when the metal plate is laid out flat (see figure 4 ), there is only the space of each "second" cut 30 between the edge of the "second" flap 31 and the remainder of the metal plate. This construction promotes the rigidity of the "second" flaps 31. Thus, when the "second" flap 31 is biased, it is the entire "second" flange 3 which flexes from the base of the U-shape.

Outre les découpes et les extrémités libres de la "seconde" aile 3, les "première" et "seconde" ailes 2, 3 sont sensiblement planes. Elles sont orientées inclinées l'une par rapport à l'autre d'un quatrième angle λ (visible sur la figure 5) par exemple de 10 à 20° de sorte que, sur une "première" portion d'aile P1 (représentée sur la figure 5), la largeur de la fente longitudinale 5 augmente d'une zone de pincement Z1 vers une zone évasée Z2 à la base de la forme en U. Cette construction favorise le maintien du support dans la fente longitudinale 5. De plus, sur une "seconde" portion d'aile P2 (représentée sur la figure 5), l'extrémité libre 32 de la "seconde" aile 3 pliée vers l'extérieur de la fente longitudinale 5 forme une zone d'introduction Z3 facilitant l'engagement du support dans la fente longitudinale 5.In addition to the cutouts and free ends of the "second" wing 3, the "first" and "second" wings 2, 3 are substantially flat. They are oriented inclined relative to each other by a fourth angle λ (visible on the figure 5 ) for example from 10 to 20 ° so that, on a "first" wing portion P1 (shown in FIG. figure 5 ), the width of the longitudinal slot 5 increases from a clamping zone Z1 to a flared zone Z2 at the base of the U-shape. This construction makes it possible to maintain the support in the longitudinal slot 5. In addition, on a " second "wing portion P2 (shown in FIG. figure 5 ), the free end 32 of the "second" wing 3 folded outwardly of the longitudinal slot 5 forms an introduction zone Z3 facilitating the engagement of the support in the longitudinal slot 5.

Comme il ressort de manière claire de la figure 5, les extrémités libres des "seconds" volets 31 sont situées entre l'extrémité libre du "premier" volet 21 et le "troisième" volet 23. Cette configuration particulière permet d'assurer un bon maintien du clip de mise à la terre 1 sur le support 100. La fente transversale 6 destinée à recevoir l'engagement du fil de terre 10 présente une largeur différente le long de sa longueur. Ainsi, dans une "troisième" partie P13 (visible sur la figure 6) correspondant à la zone dans laquelle la fente transversale 6 débouche du clip de mise à la terre 1 et à la zone d'introduction Z3, la fente transversale 6 a une largeur sensiblement constante, par exemple supérieure à celle du diamètre extérieur de la gaine isolante 12 du fil de terre 10, favorisant ainsi l'engagement du fil de terre 10 dans la fente transversale 6. Ensuite, sur une "première" partie P11 (visible sur la figure 6) de la "première" portion d'aile P1 des "première" et "seconde" ailes 2, 3, la fente transversale 6 a une largeur qui diminue progressivement jusqu'à une largeur sensiblement égale au diamètre de l'âme conductrice 11. Lors du passage du fil de terre 10 dans cette "première" partie P11, la gaine isolante 12 est ainsi coupée. Pour faciliter cette coupure, les bords de la fente transversale 6 peuvent être prévus tranchant sur cette "première" partie P11. Au fur et à mesure que la découpe est réalisée, l'écartement progressif des "première" et "seconde" ailes 2, 3 sur la "première" portion d'aile P1 favorise la découpe de la gaine isolante 12. A l'extrémité de la "première" partie P11, une fois la gaine isolante 12 coupée, l'âme conductrice 11 est en contact avec les bords de la fente transversale 6. Sur une "seconde" partie P12 de la "première" portion d'aile P1 des "première" et "seconde" ailes 2, 3, la fente transversale 6 a une largeur sensiblement constante et égale au diamètre de l'âme conductrice 11 ce qui permet d'assurer le contact électrique entre le clip de mise à la terre 1 et l'âme conductrice 11.As is clear from the figure 5 , the free ends of the "second" flaps 31 are situated between the free end of the "first" flap 21 and the "third" flap 23. This particular configuration makes it possible to ensure that the grounding clip 1 is securely held on the support 100. The transverse slot 6 for receiving the engagement of the ground wire 10 has a different width along its length. Thus, in a "third" part P13 (visible on the figure 6 ) corresponding to the area in which the transverse slot 6 opens out of the earthing clip 1 and the insertion zone Z3, the transverse slot 6 has a substantially constant width, for example greater than that of the outer diameter of the sheath insulating 12 of the ground wire 10, thus promoting the engagement of the ground wire 10 in the transverse slot 6. Then, on a "first" part P11 (visible on the figure 6 ) of the "first" wing portion P1 of the "first" and "second" wings 2, 3, the transverse slot 6 has a width which gradually decreases to a width substantially equal to the diameter of the conductive core 11. During the passage of the ground wire 10 in this "first" part P11, the insulating sheath 12 is thus cut off. To facilitate this cutting, the edges of the transverse slot 6 can be provided cutting on this "first" part P11. As the cut is made, the progressive spacing of the "first" and "second" wings 2, 3 on the "first" wing portion P1 promotes the cutting of the insulating sheath 12. At the end of the "first" part P11, once the insulating sheath 12 has been cut off, the conductive core 11 is in contact with the edges of the transverse slot 6. On a "second" part P12 of the "first" portion of wing P1 of the "first" and "second" wings 2, 3, the transverse slot 6 has a width substantially constant and equal to the diameter of the conductive core 11 which ensures electrical contact between the earthing clip 1 and the conductive core 11.

Le clip de mise à la terre 1 selon l'invention est facilement réalisable à partir par exemple d'un morceau de plaque d'acier, coupé et plié. Une fois réalisé, le clip de mise à la terre 1 peut subir des traitements thermiques pour renforcer ses caractéristiques mécaniques. Il peut également subir un traitement de surface pour le protéger des agressions environnementales.The earthing clip 1 according to the invention is easily achievable from for example a piece of steel plate, cut and folded. Once made, the earthing clip 1 can undergo heat treatments to reinforce its mechanical characteristics. It can also undergo a surface treatment to protect it from environmental aggressions.

Comme illustré sur la figure 2, pour mettre en place le clip de mise à la terre 1, on place le fil de terre 10 en regard de la fente transversale 6 dans laquelle on l'introduit. Le fil de terre 10 est ainsi reçu dans la "troisième" partie P13 la plus large de la fente transversale 6 puis dans la "première" partie P11 de la "première" portion d'aile P1 ayant une largeur qui diminue progressivement le long de laquelle les "première" et "seconde" ailes 2, 3 s'écartent progressivement et dans laquelle la gaine isolante 12 du fil de terre 10 est coupée. Le fil de terre 10 est ensuite reçu dans la "seconde" partie P12, la plus étroite de la fente transversale 6, le long de laquelle les "première" et "seconde" ailes 2, 3 s'écartent progressivement. La largeur de la "seconde" partie P12 étant similaire au diamètre de l'âme conductrice 11, toute atteinte de cette dernière est évitée. Le clip de mise à la terre 1 est présenté en face du support 100 de sorte que la fente longitudinale 5 soit sensiblement parallèle au bord concerné du support 100. Ce bord est engagé dans la fente longitudinale 5, dans un premier temps dans la zone d'introduction Z3. Les "première" et "seconde" ailes 2, 3 sont écartées élastiquement l'une de l'autre jusqu'à ce que l'épaisseur de la zone de pincement Z1 corresponde à l'épaisseur du bord du support 100. L'engagement est poursuivi jusqu'à ce que le bord du support 100 arrive en appui sur les butées formées par les "troisièmes" volets 23. Le "troisième" volet 23 garantit ainsi le bon positionnement du clip de mise à la terre 1 sur le support 100. Lors de cet engagement, les extrémités des "premiers" et "seconds" volets 21, 22 frottent contre le support 100, voire le raye ce qui permet notamment de supprimer toute salissure qui pourrait nuire à la qualité du contact électrique entre le clip de mise à la terre 1 et le support 100. Les "premiers" et "seconds" volets 21, 22 garantissent le maintien du positionnement du clip de mise à la terre 1 sur le support 100. L'engagement du fil de terre 10 dans la fente transversale 6 et l'engagement du support 100 dans la fente longitudinale 5 peuvent être successifs ou simultanés. L'utilisation du clip de mise à la terre 1 est simple et peut se faire sans mode d'emploi. Cette utilisation ne nécessite pas d'outil spécifique, au plus éventuellement un marteau pour assurer l'engagement du support dans la fente longitudinale 5. Ce type de clip de mise à la terre 1 peut néanmoins être utilisé avec un outil de mise en place automatique de type chargeur pouvant par exemple contenir une vingtaine de clips de mise à la terre 1 et permettant d'améliorer le rendement de pose.As illustrated on the figure 2 to set up the earthing clip 1, the earth wire 10 is placed facing the transverse slot 6 into which it is introduced. The ground wire 10 is thus received in the "third" portion P13 widest of the transverse slot 6 and in the "first" portion P11 of the "first" wing portion P1 having a width which decreases progressively along which the "first" and "second" wings 2, 3 gradually deviate and wherein the insulating sheath 12 of the ground wire 10 is cut. The ground wire 10 is then received in the "second" portion P12, the narrowest of the transverse slot 6, along which the "first" and "second" wings 2, 3 gradually deviate. The width of the "second" portion P12 being similar to the diameter of the conductive core 11, any attack on the latter is avoided. The earthing clip 1 is presented in front of the support 100 so that the longitudinal slot 5 is substantially parallel to the relevant edge of the support 100. This edge is engaged in the longitudinal slot 5, initially in the zone d Z3 introduction. The "first" and "second" wings 2, 3 are elastically spaced apart from one another until the thickness of the nip zone Z1 corresponds to the thickness of the edge of the support 100. The engagement is continued until the edge of the support 100 comes to bear on the abutments formed by the "third" flaps 23. The "third" flap 23 thus ensures the proper positioning of the earthing clip 1 on the support 100 During this engagement, the ends of the "first" and "second" flaps 21, 22 rub against the support 100, or even the strip which allows in particular to remove any dirt that could affect the quality of the electrical contact between the clip of 1 and the support 100. The "first" and "second" flaps 21, 22 ensure the positioning of the earthing clip 1 is maintained on the support 100. The engagement of the ground wire 10 in the transverse slot 6 and the engagement of the support 100 in the longitudinal slot 5 p may be successive or simultaneous. The use of the earthing clip 1 is simple and can be done without instructions. This use does not require a specific tool, at most possibly a hammer to ensure the engagement of the support in the longitudinal slot 5. This type of earthing clip 1 can nevertheless be used with an automatic setting tool charger type can for example contain twenty grounding clips 1 and to improve the performance of installation.

Dans la position engagée illustrée par la figure 3, le clip de mise à la terre 1 est en position et l'assemblage de mise à la terre réalisé. Les fentes longitudinale 5 et transversale 6 débouchant du même coté dudit clip de mise à la terre 1, le fil de terre 10 est coincé dans le clip de mise à la terre 1 par le support 100 au fond de la fente transversale 6. L'assemblage de mise à la terre obtenu est compact et le fil de terre 10 orienté de façon optimale, à savoir perpendiculairement à la fente longitudinale 5 et au bord du support 100. Le clip de mise à la terre 1 permet un montage sans dénudage préalable du fil de terre 10.In the committed position illustrated by the figure 3 , the earthing clip 1 is in position and the earthing assembly is made. The longitudinal 5 and transverse slots 6 opening on the same side of said earthing clip 1, the ground wire 10 is wedged in the earthing clip 1 by the support 100 at the bottom of the transverse slot 6. The putting assembly The resulting ground is compact and the ground wire is optimally oriented, namely perpendicular to the longitudinal slot 5 and the edge of the support 100. The earthing clip 1 allows a mounting without stripping of the ground wire 10.
