The wedge and the body include reciprocal means for locking (13a, 28) the wedge in the intermediate insertion position in the channel, so as to temporarily prevent the wedge from moving with respect to the body along the axis of the channel in either direction.

Description

Pince d'ancrage pour câble de télécommunications Anchor for telecommunications cable
La présente invention concerne une pince d'ancrage pour câble de télécommunications. Ce type de pince est utilisé pour ancrer un câble sur un armement disposé en façade ou en tête de poteau.The present invention relates to an anchor for telecommunication cable. This type of clamp is used to anchor a cable on a weapon arranged in front or at the head of the pole.
Le document FR 2 844 111 décrit une telle pince d'ancrage, qui comprend d'une part un corps tubulaire formant un canal convergeant, et d'autre part un coin recevant à sa périphérie une boucle du câble à ancrer et pouvant être enfoncé dans le canal du corps pour que la boucle du câble soit pincée entre le coin et les parois du corps par la tension communiquée au câble.The document FR 2 844 111 describes such an anchoring clamp, which comprises firstly a tubular body forming a converging channel, and secondly a corner receiving at its periphery a loop of the cable to be anchored and which can be driven into the channel of the body so that the loop of the cable is pinched between the corner and the walls of the body by the tension communicated to the cable.
Le coin présente un orifice traversant dans lequel on peut placer un outil, de type tournevis, cet outil venant également en appui contre un bord du corps tubulaire. Ainsi, l'opérateur peut empêcher l'enfoncement du coin pendant la phase de réglage de la tension du câble. Ensuite, lorsque l'outil est retiré, le coin est libéré et peut s'enfoncer dans le corps pour enserrer le câble.The corner has a through hole in which can be placed a tool, screwdriver type, this tool also bearing against an edge of the tubular body. Thus, the operator can prevent depression of the wedge during the adjustment phase of the cable tension. Then, when the tool is removed, the wedge is released and can sink into the body to grip the cable.
Toutefois, pendant les manipulations de réglage, le coin a une très forte tendance à reculer depuis sa position partiellement enfoncée, c'est-à-dire à se déplacer par rapport au corps dans le sens de la sortie hors du corps. En effet, ce mouvement ne peut être empêché par le simple appui du tournevis sur le bord du corps. Or, ce recul du coin gêne l'opération de réglage de la tension du câble et peut même conduire à la sortie complète du coin hors du corps, obligeant l'opérateur à refaire depuis le début son opération de mise en place et de réglage. Ce problème est encore plus important dans le cas de câbles de section ronde.However, during adjustment operations, the wedge has a very strong tendency to move back from its partially depressed position, that is to say to move relative to the body in the direction of the exit out of the body. Indeed, this movement can not be prevented by the simple support of the screwdriver on the edge of the body. However, this retreat of the corner hinders the operation of adjusting the tension of the cable and can even lead to the complete exit of the corner out of the body, forcing the operator to redo from the beginning its setting operation and adjustment. This problem is even more important in the case of round section cables.
En outre, le coin décrit dans le document FR 2 844 111 présente, sur l'un de ses bords périphériques, deux rebords décalés l'un par rapport à l'autre, et entre lesquels les câble est destiné à passer. Cette structure, si elle permet d'assurer convenablement le maintien de câbles plats autour du coin, est très mal adaptée aux câbles de section ronde qui ne sont pas suffisamment maintenus d'une part entre ces rebords décalés, et d'autre part le long du bord périphérique plan du coin. Ainsi, la structure proposée par le document FR 2 844 111 ne permet pas de maintenir les caractéristiques de la pince en termes de sécurité et de facilité de réglage pour l'application à des câbles ronds. La présente invention vise à remédier aux inconvénients mentionnés ci-dessus, en fournissant une pince d'ancrage pour câble de télécommunications qui soit d'une mise en œuvre facilitée et qui permette un excellent maintien des câbles, y compris les câbles de section ronde. A cet effet, la pince d'ancrage selon l'invention comprend : - un corps tubulaire comportant deux parois latérales sensiblement parallèles entre elles, reliées par deux parois transversales, lesdites quatre parois définissant entre elles un canal possédant un axe, ce canal étant ouvert à sa première et à sa deuxième extrémités axiales et présentant une section sensiblement rectangulaire convergeant de sa première à sa deuxième extrémités axiales ; - un coin présentant une forme complémentaire de celle du canal ménagé dans le corps, destiné à recevoir à sa périphérie une boucle du câble à ancrer et à être inséré dans le canal depuis la première extrémité, jusqu'à une position enfoncée où ladite boucle du câble est pincée entre le coin et les parois transversales du corps par la tension communiquée au câble ; et le coin et le corps comprennent des moyens de blocage réciproques dans une position intermédiaire d'insertion du coin dans le canal, lesdits moyens de blocage étant agencés pour empêcher le déplacement du coin par rapport au corps selon l'axe du canal, dans les deux sens, dans ladite position intermédiaire d'insertion. Grâce à l'invention, on peut donc réaliser un blocage temporaire du coin par rapport au corps, dans une position permettant le réglage de la tension du câble, sans risque que le coin ne s'écarte du corps.In addition, the corner described in FR 2,844,111 has, on one of its peripheral edges, two edges offset relative to each other, and between which the cable is intended to pass. This structure, if it ensures proper maintenance of flat cables around the corner, is very poorly suited to round section cables that are not sufficiently maintained on the one hand between these staggered edges, and on the other hand along the peripheral edge plane of the corner. Thus, the structure proposed by document FR 2 844 111 does not make it possible to maintain the characteristics of the clamp in terms of safety and ease of adjustment for the application to round cables. The present invention aims to remedy the disadvantages mentioned above, by providing an anchoring clamp for cable of telecommunications which is of a facilitated implementation and which allows an excellent maintenance of the cables, including the cables of round section. For this purpose, the anchoring clamp according to the invention comprises: a tubular body comprising two lateral walls substantially parallel to each other, connected by two transverse walls, said four walls defining between them a channel having an axis, this channel being open at its first and second axial ends and having a substantially rectangular section converging from its first to its second axial ends; a wedge having a shape complementary to that of the channel formed in the body, intended to receive at its periphery a loop of the cable to be anchored and to be inserted into the channel from the first end, to a depressed position where said loop of the cable is pinched between the corner and the transverse walls of the body by the voltage communicated to the cable; and the wedge and the body comprise reciprocal locking means in an intermediate insertion position of the wedge in the channel, said locking means being arranged to prevent displacement of the wedge relative to the body along the axis of the channel, in the two directions, in said intermediate insertion position. Thanks to the invention, it is possible to achieve a temporary locking of the corner relative to the body, in a position for adjusting the tension of the cable, without the risk that the corner deviates from the body.
Les opérations de mise en place et de réglage s'en trouvent donc considérablement facilitées et requièrent moins de temps, même lorsqu'il s'agit d'ancrer des câbles rondsSetting up and adjusting operations are therefore considerably easier and require less time, even when anchoring round cables
Avantageusement, les moyens de blocage ménagés sur le coin et sur le corps peuvent être agencés pour pouvoir être associés temporairement au moyen d'un organe de liaison tel qu'un tournevis. Il s'agit donc d'un outil de coincement n'appartenant pas à la pince. Selon une réalisation possible, les moyens de blocage comprennent un trou traversant ménagé transversalement dans le coin et deux orifices traversants ménagés transversalement et en vis-à-vis dans les parois latérales du corps.Advantageously, the locking means provided on the corner and on the body may be arranged to be temporarily associated by means of a connecting member such as a screwdriver. It is therefore a wedging tool not belonging to the clamp. According to one possible embodiment, the locking means comprise a through hole formed transversely in the corner and two through orifices formed transversely and vis-à-vis in the side walls of the body.
Les moyens de blocage peuvent comprendre un trou traversant ménagé transversalement dans le coin et au moins une patte en saillie sur le corps, ladite patte s'étendant au-delà de la première extrémité axiale du canal et comportant un orifice traversant transversal situé au-delà de la première extrémité axiale du canal. Par « au-delà de la première extrémité axiale du canal », on entend que la partie concernée est située, selon la direction de l'axe du canal, plus loin de la deuxième extrémité axiale du canal que ne l'est la première extrémité axiale du canal.The locking means may comprise a through hole formed transversely in the corner and at least one tab projecting from the body, said tab extending beyond the first axial end of the channel. and having a transverse through hole located beyond the first axial end of the channel. By "beyond the first axial end of the channel" is meant that the part concerned is located, in the direction of the axis of the channel, further from the second axial end of the channel than is the first end. axial of the canal.
En pratique, avec l'une et/ou l'autre des deux réalisations précitées, on place le trou du coin et le ou les orifices du corps en correspondance et on y insère un tournevis. On comprend que les dimensions du trou et du ou des orifices (typiquement le diamètre) doivent être adaptées au diamètre du tournevis afin qu'un blocage axial satisfaisant puisse être obtenu. On a ainsi de préférence des trous et orifices de diamètre légèrement plus grand que le diamètre de l'outil utilisé pour le blocage.In practice, with one and / or the other of the above two embodiments, the hole of the corner and the or orifices of the body are placed in correspondence and a screwdriver is inserted therein. It is understood that the dimensions of the hole and the orifice (s) (typically the diameter) must be adapted to the diameter of the screwdriver so that satisfactory axial locking can be obtained. There are thus preferably holes and orifices of diameter slightly larger than the diameter of the tool used for blocking.
Selon une réalisation possible, le corps comporte une patte en saillie sur chacune de ses parois latérales, chacune des deux pattes comportant un orifice traversant transversal situé au-delà de la première extrémité axiale du canal, les orifices étant en vis-à-vis l'un de l'autre.According to one possible embodiment, the body comprises a lug projecting from each of its lateral walls, each of the two lugs having a transverse through-orifice situated beyond the first axial end of the channel, the orifices being opposite one of the other.
La ou chaque patte est par exemple sensiblement parallèle à la paroi latérale correspondante et située sensiblement dans le même plan que cette paroi latérale. Avantageusement, le coin peut comporter, à un bord axial, deux rebords latéraux en vis-à-vis entre lesquels le câble à ancrer est destiné à passer. Cette structure permet d'obtenir un bien meilleur maintien du câble autour du coin et un meilleur réglage de la tension, en particulier lorsqu'il s'agit d'un câble rond. Afin d'améliorer encore ce maintien, on peut prévoir que les rebords latéraux s'étendent le long de sensiblement tout ledit bord axial (c'est- à-dire qu'ils ne soient pas localisés le long de ce bord).The or each tab is for example substantially parallel to the corresponding side wall and located substantially in the same plane as the side wall. Advantageously, the wedge may comprise, at an axial edge, two lateral edges facing each other between which the cable to be anchored is intended to pass. This structure makes it possible to obtain a much better maintenance of the cable around the corner and a better adjustment of the tension, in particular when it is a round cable. To further improve this retention, it can be provided that the side flanges extend along substantially all of said axial edge (i.e. they are not located along this edge).
Par ailleurs, le coin peut comporter une gorge périphérique destinée à recevoir le câble à ancrer, ladite gorge présentant un fond incurvé. Cette géométrie vise à permettre un maintien amélioré du câble autour du coin, surtout lorsqu'il s'agit d'un câble rond.Furthermore, the corner may comprise a peripheral groove for receiving the cable to be anchored, said groove having a curved bottom. This geometry aims to allow an improved maintenance of the cable around the corner, especially when it comes to a round cable.
On décrit à présent, à titre d'exemple non limitatif, un mode de réalisation possible de l'invention, en référence aux figures annexées :We will now describe, by way of nonlimiting example, a possible embodiment of the invention, with reference to the appended figures:
La figure 1 est une vue en perspective de la pince selon l'invention, le coin n'étant pas inséré dans le corps ; La figure 2 est une vue en perspective de cette pince lorsque le coin est en position intermédiaire d'insertion dans le canal du corps (le câble n'étant pas représenté) ; etFigure 1 is a perspective view of the clamp according to the invention, the wedge is not inserted into the body; FIG. 2 is a perspective view of this clamp when the wedge is in the intermediate position of insertion into the channel of the body (the cable not being represented); and
La figure 3 est une vue latérale de cette pince lorsque le coin est en position enfoncé et le câble serré.Figure 3 is a side view of this clamp when the wedge is in the depressed position and the cable tightened.
Comme illustré sur la figure 1 , la pince 1 comprend un corps 2 tubulaire et un coin 3. Dans la réalisation représentée, le coin 3 est relié au corps 2 par un filament 4 déformable, et ces différents éléments sont réalisés d'une seule pièce par moulage d'une matière plastique. Le corps 2 comprend deux parois latérales 5a, 5b, sensiblement trapézoïdales et parallèles entre elles, reliées par deux parois transversales 6a, 6b sensiblement rectangulaires. Est ainsi défini entre ces quatre parois 5a, 5b, 6a, 6b un canal 7 possédant un axe 8, qui est ouvert à sa première et à sa deuxième extrémités axiales 9, 10. Le canal 7 présente une section sensiblement rectangulaire convergeant de sa première à sa deuxième extrémités axiales 9, 10.As illustrated in Figure 1, the clamp 1 comprises a tubular body 2 and a wedge 3. In the embodiment shown, the wedge 3 is connected to the body 2 by a deformable filament 4, and these different elements are made in one piece by molding a plastic material. The body 2 comprises two lateral walls 5a, 5b, substantially trapezoidal and parallel to each other, connected by two substantially rectangular transverse walls 6a, 6b. Is thus defined between these four walls 5a, 5b, 6a, 6b a channel 7 having an axis 8, which is open at its first and second axial ends 9, 10. The channel 7 has a substantially rectangular section converging from its first at its second axial ends 9, 10.
Le corps 2 comporte en outre, sur chacune de ses parois latérales 5a, 5b, une patte 11a, 11b sensiblement parallèle à la paroi latérale correspondante et située sensiblement dans le même plan que cette paroi latérale, mais faisant saillie au-delà du bord 12 du corps 2 situé du côté de la première extrémité axiale 9 du canal 7. Chaque patte 11a, 11b comporte un orifice 13a, 13b traversant transversal, situé au-delà de la première extrémité axiale 9 du canal 7, les orifices13a, 13b étant en vis-à-vis l'un de l'autre. Dans la réalisation représentée, les orifices13a, 13b sont circulaires et présentent le même axe transversal 14.The body 2 further comprises, on each of its side walls 5a, 5b, a lug 11a, 11b substantially parallel to the corresponding side wall and located substantially in the same plane as the side wall, but protruding beyond the edge 12 the body 2 located on the side of the first axial end 9 of the channel 7. Each lug 11a, 11b has a hole 13a, 13b transverse transverse, located beyond the first axial end 9 of the channel 7, the orifices13a, 13b being in vis-à-vis one another. In the embodiment shown, the orifices 13a, 13b are circular and have the same transverse axis 14.
Par ailleurs, le corps 2 comprend des moyens d'accrochage, composés d'une anse 15 en forme de U. L'anse 15 comporte d'une part une branche de liaison 16 s'étendant dans le prolongement d'une paroi transversale 6a, du côté de la première extrémité axiale 9 du canal 7, et d'autre part une branche d'accrochage 17. Les deux branches 16, 17 peuvent être rapprochées l'une de l'autre du fait de l'élasticité de l'anse 15.Furthermore, the body 2 comprises hooking means, composed of a loop 15 in the shape of a U. The handle 15 comprises on the one hand a connecting branch 16 extending in the extension of a transverse wall 6a on the side of the first axial end 9 of the channel 7, and on the other hand a hooking branch 17. The two branches 16, 17 can be brought closer to each other because of the elasticity of the handle 15.
La branche d'accrochage 17 présente une section transversale rectangulaire et est munie, à son extrémité libre, d'une tête 18 élargie apte à être engagée dans un logement 19 ménagé dans le corps 2 et débouchant latéralement. Ce logement 19 présente une partie principale 20 ayant des dimensions suffisantes pour recevoir la tête 18, prolongée par une fente 21 débouchant du côté du bord 12 du corps 2, près de l'anse 15. La fente 21 est apte à recevoir la branche d'accrochage 17 et possède des dimensions inférieures à celles de la tête 18. Le logement 19 comporte une zone en retrait 22, entre la partie principale 20 et la fente 21 , qui ne débouche pas latéralement, et qui est apte à recevoir au moins une partie de la tête 18 et à la bloquer, lorsque l'anse 15 est repliée et fixée au corps 2.The hooking branch 17 has a rectangular cross section and is provided at its free end with an enlarged head 18 adapted to be engaged in a housing 19 formed in the body 2 and opening laterally. This housing 19 has a main portion 20 having sufficient dimensions to receive the head 18, extended by a slot 21 opening on the side of the edge 12 of the body 2, near the handle 15. The slot 21 is adapted to receive the attachment branch 17 and has dimensions smaller than those of the head 18. The housing 19 has a recessed area 22, between the main part 20 and the slot 21, which does not open laterally, and which is adapted to receive at least a portion of the head 18 and to block it, when the handle 15 is folded and fixed to the body 2.
L'anse 15 est destinée à être associée à un armement (non représenté), tel qu'un piton disposé en façade ou en tête de poteau, puis à être verrouillée, la tête 18 étant engagée et bloquée dans la zone en retrait 22 du logement 19. Après cet engagement, la tête 18 ne peut plus sortir du logement 19 sans intervention humaine, ce qui évite un décrochage par exemple sous l'action d'un vent violent.The handle 15 is intended to be associated with an armament (not shown), such as a stud placed in front or at the head of the post, then to be locked, the head 18 being engaged and locked in the recessed area 22 of the housing 19. After this commitment, the head 18 can not leave housing 19 without human intervention, which prevents a stall for example under the action of a strong wind.
Le coin 3 présente une forme complémentaire de celle du canal 7 ménagé dans le corps 2. Il présente deux faces latérales 23a, 23b sensiblement parallèles et triangulaires, espacées l'une de l'autre, et comprend un bord axial 24 opposé à la pointe 25 du coin 3. Le coin 3 comporte, à son bord axial 24, deux rebords 26a, 26b latéraux en vis-à-vis, situés chacun sensiblement dans le même plan que la face latérale 23a, 23b correspondante dont ils constituent les prolongements. Ces rebords 26a, 26b sont relativement hauts (par exemple de l'ordre de 10 mm) et s'étendent le long de sensiblement tout ledit bord axial 24. Le filament 4 est par exemple associé à l'un de ces rebords.The wedge 3 has a shape complementary to that of the channel 7 formed in the body 2. It has two substantially parallel and triangular lateral faces 23a, 23b, spaced apart from one another, and comprises an axial edge 24 opposite the tip. The wedge 3 has, at its axial edge 24, two lateral flanges 26a, 26b vis-à-vis, each located substantially in the same plane as the corresponding lateral face 23a, 23b of which they constitute the extensions. These flanges 26a, 26b are relatively high (for example of the order of 10 mm) and extend along substantially all of said axial edge 24. The filament 4 is for example associated with one of these flanges.
Le coin 3 comporte également une gorge périphérique 27 dont le fond est incurvé et qui, au niveau du bord axial 24, est située entre les deux rebords 26a, 26b. Enfin, le coin 3 comporte un trou 28 traversant possédant un axe 29 orienté transversalement. Dans la réalisation représentée, le trou 28 est circulaire et de diamètre comparable à celui des orifices13a, 13b du corps 2.The wedge 3 also has a peripheral groove 27 whose bottom is curved and which, at the axial edge 24, is located between the two flanges 26a, 26b. Finally, the wedge 3 has a through hole 28 having a transversely oriented axis 29. In the embodiment shown, the hole 28 is circular and of comparable diameter to that of the orifices 13a, 13b of the body 2.
On décrit à présent la mise en œuvre de la pince 1 pour l'ancrage d'un câble, en référence aux figures 2 et 3. Une boucle 30 du câble est introduite dans le canal 7 du corps 2 et placée autour du coin 3, en étant logée dans la gorge périphérique 27 à fond incurvé et, localement, entre les rebords 26a, 26b. Puis le coin 3 est inséré dans le canal 7, la pointe 25 étant introduite dans le canal 7 depuis la première extrémité axiale 9. Le coin est inséré dans le canal 7 jusqu'à ce que l'axe 29 du trou 28 du coin 3 soit sensiblement confondu avec l'axe 14 des orifices 13a, 13b du corps 2. Un outil de dimensions adaptées, par exemple un tournevis, est alors introduit suivant cet axe commun 29, 14, afin de bloquer temporairement le coin 3 par rapport au corps 2, dans cette position intermédiaire d'insertion (figure 2). L'opérateur procède alors au réglage de la tension du câble. Puis il retire l'outil, tout en maintenant la tension appliquée au câble, et le coin 3 vient donc s'insérer davantage dans le canal 7 du corps 9, jusqu'à la position d'enfoncement illustrée sur la figure 3. Dans cette position, la boucle 30 du câble est pincée entre le coin 3 et les parois transversales 6a, 6b du corps 2 par la tension communiquée au câble. Ainsi, l'invention apporte une amélioration déterminante à la technique antérieure, en fournissant une pince d'ancrage permettant un réglage facilité de la tension du câble à ancrer et un maintien amélioré de ce câble, cette pince étant particulièrement adaptée aux câbles ronds.The implementation of the clamp 1 for the anchoring of a cable is now described, with reference to FIGS. 2 and 3. A loop 30 of the cable is introduced into the channel 7 of the body 2 and placed around the wedge 3, being housed in the peripheral groove 27 with a curved bottom and, locally, between the flanges 26a, 26b. Then the wedge 3 is inserted into the channel 7, the tip 25 being inserted into the channel 7 from the first axial end 9. The wedge is inserted into the channel 7 until the axis 29 of the hole 28 of the corner 3 is substantially coincident with the axis 14 of the orifices 13a, 13b of the body 2. A tool of suitable dimensions, for example a screwdriver, is then introduced along this common axis 29, 14, in order to temporarily block the wedge 3 with respect to the body 2, in this intermediate insertion position (FIG. ). The operator then proceeds to adjust the cable tension. Then he removes the tool, while maintaining the tension applied to the cable, and the wedge 3 is thus inserted further into the channel 7 of the body 9, to the depression position illustrated in FIG. position, the loop 30 of the cable is pinched between the corner 3 and the transverse walls 6a, 6b of the body 2 by the voltage communicated to the cable. Thus, the invention provides a decisive improvement to the prior art, providing an anchor for easy adjustment of the tension of the cable to anchor and improved maintenance of this cable, this clip being particularly suitable for round cables.
Il va de soi que l'invention n'est pas limitée au mode de réalisation décrit ci-dessus à titre d'exemple mais qu'elle en embrasse au contraire toutes les variantes de réalisation. It goes without saying that the invention is not limited to the embodiment described above as an example but that it encompasses all variants.
