Abstract

The sleeve for an electric cable comprises two bodies (2, 3) and a hinge (4). Each body (2, 3) is flexible in the profile thereof, has, in the absence of mechanical stress, a position of rest in which it is curved whereas it is designed for being bent from the position of rest. The sleeve has an open position in which the bodies (2, 3) are separated from one another when in the position of rest, has a first stable closed position in which a first body (3) receives the second body (2) and has a second stable closed position in which the second body (2) receives the first body (3). The sleeve is designed for being deformed by folding the hinge (4) and to flex in the profile of these bodies (2, 3) in order to pass from the open position into one or other said stable closed positions.

Description

Manchon pour câble électrique DOMAINE DE L'INVENTION La présente invention concerne un manchon pour câble électrique. FIELD OF THE INVENTION The present invention relates to a sleeve for an electric cable.
ARRIÈRE-PLAN TECHNOLOGIQUE Les manchons sont fréquemment employés dans les installations électriques, lorsqu'ils sont réalisés en matériau isolant, pour isoler un élément électrique de l'environnement extérieur afin de protéger notamment l'utilisateur des contacts électriques directs avec cet élément, tel que par exemple un câble électrique et/ou une cosse pour borne de raccordement sertie à l'extrémité de ce câble.BACKGROUND ART Sleeves are frequently used in electrical installations, when they are made of insulating material, to isolate an electrical element from the external environment, in particular to protect the user from direct electrical contacts with this element, such as for example, an electric cable and / or a lug for crimped connection terminal at the end of this cable.
On connaît déjà notamment par le brevet français 2 841 048 des manchons isolants pour cosse comportant deux coques rigides en forme de gouttière chacune reliée longitudinalement par une charnière à un corps rigide et mobiles entre une position ouverte dans laquelle elles sont écartées l'une de l'autre et une position fermée dans laquelle les bords libres des coques sont l'un contre l'autre avec le manchon qui présente alors une section globalement circulaire. Le corps présente en outre un arceau d'encliquetage sur la cosse tandis que les gouttières présentent des moyens de fixation mutuels pour être maintenues bord à bord en position fermée autour de la cosse. L'invention vise à fournir un manchon simple, économique et performant, notamment en ce qui concerne son mode de fixation sur le câble électrique.French patent 2,841,048 already discloses insulating sleeves for lugs comprising two rigid gutter-shaped shells each connected longitudinally by a hinge to a rigid body and movable between an open position in which they are separated from each other. another and a closed position in which the free edges of the shells are against each other with the sleeve which then has a generally circular section. The body further has a ratchet bar on the lug while the gutters have mutual attachment means to be held edge to edge in the closed position around the lug. The aim of the invention is to provide a simple, economical and efficient sleeve, particularly as regards its method of attachment to the electric cable.
Elle propose à cet effet un manchon pour câble électrique comportant deux gouttières et une charnière ; caractérisé en ce que chaque dite gouttière est flexible en profil, s'étend d'un premier bord longitudinal rattaché à ladite charnière à un second bord longitudinal libre, admet en l'absence de sollicitation mécanique une position de repos où elle est incurvée avec ledit premier bord longitudinal qui est à distance du second bord longitudinal tandis qu'elle est adaptée à être fléchie à partir de ladite position de repos dans le sens où ladite distance varie ; ledit manchon admettant une position ouverte dans laquelle lesdites gouttières sont à l'écart l'une de l'autre en position de repos, la surface concave de chaque dite gouttière regardant un espace alors vide, admettant une première position fermée stable où ledit espace d'une première desdites gouttières reçoit la seconde gouttière et admettant une seconde position fermée stable où ledit espace de la seconde gouttière reçoit la première gouttière, ledit manchon étant adapté à être déformé par pliage de ladite charnière et flexion en profil desdites gouttières pour passer de ladite position ouverte à l'une ou l'autre desdites positions fermées stables, ladite première gouttière fléchissant avec ladite distance qui augmente puis diminue pour recevoir ladite seconde gouttière lors du passage de ladite position ouverte à ladite première position fermée, ladite seconde gouttière fléchissant avec ladite distance qui augmente puis diminue pour recevoir ladite première gouttière lors du passage de ladite position ouverte à ladite seconde position fermée.It proposes for this purpose a sleeve for electric cable having two gutters and a hinge; characterized in that each said channel is flexible in profile extends from a first longitudinal edge attached to said hinge to a second free longitudinal edge, admitted in the absence of mechanical stress a rest position where it is curved with said first longitudinal edge which is spaced from the second longitudinal edge while being adapted to be flexed from said rest position in the sense that said distance varies; said sleeve allowing an open position in which said gutters are apart from each other in the rest position, the concave surface of each said gutter looking at a space then empty, admitting a first stable closed position where said space d a first of said gutters receives the second gutter and admitting a second stable closed position where said space of the second gutter receives the first gutter, said sleeve being adapted to be deformed by folding of said hinge and bending in profile said gutters to move from said open position to the one or the other of said stable closed positions, said first gutter flexing with said distance which increases and then decreases to receive said second gutter when passing from said open position to said first closed position, said second gutter flexing with said distance which increases then decreases to receive said first gutter when passing from said open position to said second closed position.
Ainsi, pour poser le manchon selon l'invention sur un câble électrique, pour lequel ce manchon a la dimension appropriée, on dispose indifféremment ce câble dans l'espace que regarde la surface concave de l'une ou de l'autre des deux gouttières puis l'on dispose cette gouttière dans l'autre gouttière afin d'amener Ie manchon en position fermée.Thus, to put the sleeve according to the invention on an electric cable, for which this sleeve has the appropriate dimension, it is indifferently available this cable in the space that looks the concave surface of one or the other of the two gutters then this gutter is placed in the other gutter to bring the sleeve in the closed position.
Il est ainsi simple et rapide de faire passer le manchon de sa position ouverte à l'une ou l'autre de ses positions fermées stables.It is thus simple and fast to move the sleeve from its open position to one or other of its stable closed positions.
La forme générale simple de l'embout ainsi que sa capacité à recevoir le câble indifféremment dans l'une ou l'autre des gouttières, permettent une manipulation facile et intuitive pour l'utilisateur.The simple general shape of the nozzle and its ability to receive the cable indifferently in one or other of the gutters, allow easy and intuitive handling for the user.
Le recouvrement partiel des gouttières assure un maintien particulièrement fiable du manchon autour du câble, le manchon selon l'invention offrant ainsi une grande sécurité d'utilisation.The partial overlap of the gutters ensures a particularly reliable maintenance of the sleeve around the cable, the sleeve according to the invention thus offering great safety of use.

Comme on le verra ci-après, le manchon admet une position ouverte représentée en figures 1 à 4 dans laquelle les gouttières sont à l'écart l'une de l'autre ainsi qu'une première position fermée stable représentée en figures 5 et 6 dans laquelle la gouttière 2 est emboîtée dans la gouttière 3 et une seconde position fermée stable, représentée en figures 7 et 8, similaire à la première position fermée stable mais dans laquelle la gouttière 3 est emboîtée dans la gouttière 2.The sleeve is here made in one piece of electrically insulating material, here a molded thermoplastic of the family of polyamides. As will be seen below, the sleeve has an open position shown in Figures 1 to 4 in which the gutters are spaced from each other and a first stable closed position shown in Figures 5 and 6 in which the channel 2 is nested in the gutter 3 and a second stable closed position, shown in Figures 7 and 8, similar to the first stable closed position but in which the channel 3 is nested in the gutter 2.
Sur les figures 1 à 4 le manchon est représenté dans sa position ouverte, avec les gouttières 2 et 3 en position de repos en l'absence de sollicitation mécanique. Dans sa position de repos, la gouttière 2 présente un profil en arc de cercle. Elle s'étend d'un premier bord longitudinal 7 relié à la charnière 4 à un second bord longitudinal libre 9 à distance du bord 7, cette gouttière étant délimitée par une surface concave 15 à l'intérieur de la gouttière et une surface convexe 16 à l'extérieur de la gouttière. Sur toute sa longueur, le profil en arc de cercle de la gouttière 2 est à diamètre constant et présente une étendue angulaire entre le bord libre 9 et le bord lié 7 plus grand que 180°, environ 315° dans l'exemple illustré donnant à Ia gouttière 2 une forme en C.In Figures 1 to 4 the sleeve is shown in its open position, with the gutters 2 and 3 in the rest position in the absence of mechanical stress. In its rest position, the gutter 2 has a profile in an arc. It extends from a first longitudinal edge 7 connected to the hinge 4 to a second free longitudinal edge 9 at a distance from the edge 7, this channel being delimited by a concave surface 15 inside the gutter and a convex surface 16 outside the gutter. Throughout its entire length, the arcuate profile of the gutter 2 is of constant diameter and has an angular extent between the free edge 9 and the bound edge 7 greater than 180 °, approximately 315 ° in the example illustrated giving The gutter 2 a form C.
La paroi de la gouttière 2 est d'épaisseur constante et ondulée selon une amplitude constante sur toute sa longueur, chaque ondulation étant constituée d'un creux 5 et d'une bosse 6. Ces ondulations forment une succession de nervurages qui donnent à la gouttière une forme annelée.The wall of the gutter 2 is of constant thickness and waved at a constant amplitude over its entire length, each corrugation consisting of a hollow 5 and a hump 6. These corrugations form a succession of ribs which give the gutter a ring shape.
La gouttière 2 est flexible en profil, c'est-à-dire qu'elle est adaptée à se déformer suivant des directions contenues dans des plans transversaux à la direction longitudinale du manchon pour fléchir à partir de sa position de repos dans le sens où la distance entre le bord 7 et le bord 9 varie et à revenir dans sa position de repos lorsqu'elle n'est plus soumise à une sollicitation mécanique. La gouttière 3 est identique à la gouttière 2 si ce n'est qu'elle présente une conformation en image miroir de la gouttière 2 en position de repos. La gouttière 3 s'étend ainsi d'un premier bord longitudinal 8 relié à la charnière 4 à un second bord longitudinal libre 10 à distance du bord 8, cette gouttière étant délimitée par une surface concave 17 à l'intérieur de la gouttière et une surface convexe 18 à l'extérieur de la gouttière.Gutter 2 is flexible in profile, that is to say it is adapted to deform in directions contained in planes transverse to the longitudinal direction of the sleeve to bend from its rest position in the direction where the distance between the edge 7 and the edge 9 varies and return to its rest position when it is no longer subject to mechanical stress. The gutter 3 is identical to the gutter 2 except that it has a mirror image conformation of the gutter 2 in the rest position. The channel 3 thus extends from a first longitudinal edge 8 connected to the hinge 4 to a second free longitudinal edge 10 at a distance from the edge 8, this channel being delimited by a concave surface 17 inside the gutter and a convex surface 18 outside the gutter.
La charnière 4 est une languette souple allongée à bords longitudinaux parallèles et présentant une forme générale rectangulaire lorsque le manchon est dans sa position ouverte. La languette souple est réalisée dans le même matériau que les gouttières 2 et 3 mais présente une épaisseur plus faible que celle des gouttières 2 et 3 (figure 3) afin d'obtenir la souplesse recherchée.The hinge 4 is an elongated flexible tongue with parallel longitudinal edges and having a generally rectangular shape when the sleeve is in its open position. The flexible tongue is made of the same material as the gutters 2 and 3 but has a lower thickness than the gutters 2 and 3 (Figure 3) to obtain the desired flexibility.
Dans la position ouverte du manchon, les gouttières 2 et 3 sont à l'écart l'une de l'autre et les surfaces concaves 15 et 17 des gouttières regardent un espace alors vide tandis que la languette souple 4 est dans une position plate.In the open position of the sleeve, the gutters 2 and 3 are apart from each other and the concave surfaces 15 and 17 of the gutters look at a gap then empty while the flexible tongue 4 is in a flat position.
Dans la première position fermée à vide (en l'absence d'élément électrique à l'intérieur du manchon), représentée en figures 5 et 6, l'espace de la gouttière 2 reste vide et la surface concave 17 de la gouttière 3 enveloppe alors la surface convexe 16 de la gouttière 2 de sorte que les gouttières se recouvrent sur au moins un quart du périmètre que présente le manchon dans la première position fermée. Dans l'exemple illustré, les gouttières se recouvrent sur environ un demi-périmètre.In the first closed vacuum position (in the absence of electrical element inside the sleeve), shown in Figures 5 and 6, the space of the channel 2 remains empty and the concave surface 17 of the gutter 3 envelope then the convex surface 16 of the gutter 2 so that the gutters overlap on at least a quarter of the perimeter that the sleeve presents in the first closed position. In the example shown, the gutters overlap on about half a perimeter.
Dans la seconde position fermée à vide, représentée en figures 7 et 8, similaire à la première position fermée mais où les gouttières 2 et 3 sont échangées, l'espace de la gouttière 3 reste vide et la surface concave 15 de la gouttière 2 enveloppe alors la surface convexe 18 de la gouttière 3 de sorte que les gouttières se recouvrent sur environ un demi-périmètre.In the second closed vacuum position, shown in Figures 7 and 8, similar to the first closed position but where the gutters 2 and 3 are exchanged, the space of the gutter 3 remains empty and the concave surface 15 of the gutter 2 envelope then the convex surface 18 of the gutter 3 so that the gutters overlap on about half a perimeter.
Dans ces deux positions fermées, la languette souple est pliée. La cosse 11 (figure 9) comporte une portion plate 12 présentant un trou de passage pour la tige de la borne de raccordement et une portion tubulaire 13 dans laquelle est reçue l'extrémité dénudée d'un câble électrique 14, la portion 13 étant sertie sur cette extrémité par un tronçon intermédiaire à contour hexagonal.In these two closed positions, the flexible tongue is folded. The lug 11 (FIG. 9) comprises a flat portion 12 having a through hole for the rod of the connection terminal and a tubular portion 13 in which the bare end of an electric cable is received. 14, the portion 13 being crimped on this end by an intermediate section with hexagonal contour.
On va maintenant décrire l'opération d'emboîtement du manchon 1 autour de la portion tubulaire 13 de la cosse 11 et du câble 14 à l'aide des figures 10 et 11. Sur la figure 11 , le manchon est représenté légèrement tourné par rapport à la position qu'il occupe sur la figure 10 afin de rendre plus visible la languette souple 4.We will now describe the engagement operation of the sleeve 1 around the tubular portion 13 of the lug 11 and the cable 14 with the help of Figures 10 and 11. In Figure 11, the sleeve is shown slightly rotated relative to at the position it occupies in FIG. 10 in order to make the flexible tongue 4 more visible.
La première étape consiste à emboîter la cosse 11 et la câble 14 dans l'une ou l'autre des gouttières du manchon en position ouverte. Si la cosse et le câble sont emboîtés dans la gouttière 2, la seconde étape consiste alors à faire passer le manchon dans sa première position stable fermée (figures 5 et 6) tandis que si la cosse et le câble sont emboîtés dans la gouttière 3, la seconde étape consiste alors à faire passer le manchon dans sa seconde position stable fermée (figures 7 et 8). Dans l'exemple illustré la cosse et le câble sont emboîtés dans la gouttière 2.The first step consists in fitting the lug 11 and the cable 14 in one or the other of the gutters of the sleeve in the open position. If the lug and the cable are nested in the gutter 2, the second step then consists in passing the sleeve into its first stable closed position (FIGS. 5 and 6) whereas if the lug and the cable are nested in the gutter 3, the second step is then to pass the sleeve into its second closed stable position (Figures 7 and 8). In the example shown, the lug and the cable are nested in the trough 2.
Pour cela l'opérateur vient appuyer les bords 7 et 9 de la gouttière 2 contre la portion 13 de la cosse 11 et la portion d'extrémité du câble 14. La gouttière 2 fléchit et passe alors sous cette action mécanique de sa position de repos à une position de travail où les bords 7 et 9 de la gouttière 2 s'écartent, la distance les séparant augmentant, pour laisser passer la portion 13 de la cosse 11 et la portion d'extrémité du câble 14 afin qu'elles occupent l'espace, initialement vide, situé à l'intérieur de la gouttière 2, en regard de la surface concave 15. Au cours de cette opération d'emboîtement, les bords 7 et 9 après s'être écartés pour laisser passer la portion 13 de la cosse et la portion d'extrémité du câble 14 se rapprochent de nouveau l'un de l'autre (la distance qui les sépare diminue) par rappel élastique de la paroi de la gouttière 2 qui se referme alors autour de la portion 13 de la cosse 11 et du câble 14. La seconde étape consiste à emboîter de façon similaire la gouttière 2 dans la gouttière 3 pour faire passer le manchon 1 dans sa première position fermée stable. Pour cela l'opérateur vient mettre en contact le bord 10 de la gouttière 3 contre la surface convexe 16 de la gouttière 2 pour le faire glisser le long de cette surface. L'épaisseur réduite de la languette 4 offre une souplesse qui lui permet d'être déformée pour plier et former une charnière autour de laquelle pivote la gouttière 3 par rapport à la gouttière 2. La pression exercée par l'opérateur sur la gouttière 3 tend à faire passer la gouttière 3 de sa position de repos à une position de travail dans laquelle les bords longitudinaux 8 et 10 s'écartent l'un de l'autre, la distance les séparant augmentant, pour laisser passer la gouttière 2 afin qu'elle occupe l'espace, initialement vide, situé à l'intérieur de la gouttière 3 en regard de la surface concave 17.For this the operator comes to support the edges 7 and 9 of the channel 2 against the portion 13 of the lug 11 and the end portion of the cable 14. The gutter 2 bends and then passes under this mechanical action of its rest position at a working position where the edges 7 and 9 of the trough 2 deviate, the distance separating them increasing, to let the portion 13 of the lug 11 and the end portion of the cable 14 so that they occupy the space, initially empty, located inside the gutter 2, facing the concave surface 15. During this nesting operation, the edges 7 and 9 after having spread to pass the portion 13 of the pod and the end portion of the cable 14 come closer to each other (the distance that separates them decreases) by elastic return of the wall of the gutter 2 which then closes around the portion 13 of the lug 11 and the cable 14. The second step consists of similarly eject the gutter 2 in the gutter 3 to pass the sleeve 1 in its first stable closed position. For this the operator comes to contact the edge 10 of the channel 3 against the convex surface 16 of the channel 2 to slide along this surface. The reduced thickness of the tongue 4 provides a flexibility that allows it to be deformed to fold and form a hinge around which pivots the gutter 3 with respect to the gutter 2. The pressure exerted by the operator on the gutter 3 tends to move the gutter 3 from its rest position to a working position in which the longitudinal edges 8 and 10 deviate from one another, the distance separating them increasing, to let the gutter 2 so that it occupies the space, initially empty, located inside the gutter 3 facing the concave surface 17.
Au cours de cette opération d'emboîtement, les bords 8 et 10 après s'être écartés pour laisser passer la gouttière 2 se rapprochent de nouveau l'un de l'autre (la distance qui les sépare diminue) par rappel élastique de la paroi de la gouttière 3 qui se referme alors autour de la gouttière 2. Dans cette position fermée, la surface concave 15 et une partie de la surface concave 17 regardent la cosse 11 et la portion d'extrémité du câble 14 tandis que l'autre partie de la surface concave 17 regarde la surface convexe 16 de la gouttière 2.During this interlocking operation, the edges 8 and 10 after having moved apart to allow the gutter 2 to come closer to one another (the distance which separates them decreases) by elastic return of the wall the gutter 3 which then closes around the gutter 2. In this closed position, the concave surface 15 and a portion of the concave surface 17 look at the lug 11 and the end portion of the cable 14 while the other part the concave surface 17 looks at the convex surface 16 of the gutter 2.
Lors de l'opération d'emboîtement de la gouttière 2 dans la gouttière 3, les creux 5 de la gouttière 2 forment des glissières à l'intérieur desquels coulissent les creux 5 de la gouttière 3 tandis que les bosses 6 de la gouttière 3 forment des glissières à l'intérieur desquelles coulissent les bosses 6 de la gouttière 2.During the interlocking operation of the trough 2 in the trough 3, the troughs 5 of the trough 2 form sliders within which the troughs 5 of the trough 3 slide while the bumps 6 of the trough 3 form slides inside which slide the bumps 6 of the gutter 2.
Les dimensions identiques des gouttières 2 et 3 au repos font que lorsque l'une des gouttières est emboîtée dans l'autre, chaque gouttière exerce sur l'autre des contraintes mécaniques permanentes. Dans l'exemple illustré, lorsque le manchon est dans la première position fermée la paroi de la gouttière 3 exerce une pression contre la paroi de la gouttière 2 (en raison des forces de rappel élastiques engendrées par l'emboîtement) assurant le maintien stable de la gouttière 2 autour de la cosse et du câble.The identical dimensions of the gutters 2 and 3 at rest that when one of the gutters is nested in the other, each gutter exerts on the other permanent mechanical stresses. In the illustrated example, when the sleeve is in the first closed position, the wall of the gutter 3 exerts a pressure against the wall of the gutter 2 (due to the elastic restoring forces generated by the interlocking) ensuring the stable holding of the gutter 2 around the pod and the cable.
Le recouvrement partiel des gouttières renforce l'emboîtement stable et permanent et empêche les ouvertures intempestives de ce manchon par exemple lors d'une flexion du câble 14. Les gouttières du manchon présentent également une flexibilité selon la direction longitudinale pour épouser la forme du câble lorsque celui-ci est fléchi.The partial overlap of the gutters reinforces the stable and permanent interlocking and prevents the untimely openings of this sleeve, for example during bending of the cable 14. The gutters of the sleeve also have flexibility in the longitudinal direction to match the shape of the cable when it is bent.
Les opérations d'emboîtement de la cosse dans la gouttière 3 puis de passage du manchon dans la seconde position fermée sont réalisées de façon similaire si ce n'est que les gouttières 2 et 3 sont échangées.The nesting operations of the lug in the gutter 3 and then passage of the sleeve in the second closed position are performed similarly except that the gutters 2 and 3 are exchanged.
Les opérations d'ouverture puis de retrait du manchon 1 de la cosseThe operations of opening and removing the sleeve 1 of the pod
11 et du câble 14 sont réalisées à l'inverse des opérations d'emboîtement et de fermeture du manchon décrites ci-dessus. Un autre mode de réalisation du manchon est représenté en figures11 and the cable 14 are made in contrast to the socket interlocking and closing operations described above. Another embodiment of the sleeve is shown in FIGS.
12 à 17. D'une manière générale, on a employé pour les éléments similaires les mêmes références, mais additionnées pour chaque mode de réalisation d'un chiffre 100.12 to 17. In general, the same references have been used for similar elements, but added for each embodiment of a number 100.
Les gouttières 102 et 103 de ce manchon 101 sont des gouttières présentant chacune sur toute leur longueur un profil en arc de cercle avec une étendue angulaire globalement constante et environ égale à 315° et un diamètre régulièrement variable pour former dans l'exemple illustré deux gouttières de forme générale tronconique.Gutters 102 and 103 of this sleeve 101 are gutters each having, over their entire length, an arcuate profile with a generally constant angular extent and approximately equal to 315 ° and a regularly variable diameter to form, in the illustrated example, two gutters. of frustoconical general shape.
Les parois des gouttières 102 et 103 sont d'épaisseur constante et ondulées selon une amplitude constante sur toute leur longueur, chaque ondulation étant constituée d'un creux 105 et d'une bosse 106.The walls of the gutters 102 and 103 are of constant thickness and waved at a constant amplitude over their entire length, each corrugation consisting of a hollow 105 and a bump 106.
Les gouttières 102 et 103 sont reliées par une languette souple 104 à bords longitudinaux parallèles.Gutters 102 and 103 are connected by a flexible tongue 104 with parallel longitudinal edges.
La forme tronconique des gouttières permet d'extraire de façon simple et rapide le manchon du moule en évitant aux bosses 106 de venir en butée contre les portions saillantes du moule lors de l'opération d'extraction. La conicité est déterminée en fonction de la pente nécessaire au démoulage et en fonction de l'amplitude des ondulations.The frustoconical shape of the gutters makes it possible to extract the sleeve from the mold in a simple and rapid manner, avoiding the bumps 106 coming into abutment against the projecting portions of the mold during the extraction operation. The taper is determined according to the slope required for demolding and as a function of the amplitude of the corrugations.
Ce manchon coopère avec le câble 14 comme le manchon 1 , les portions de plus petit diamètre des gouttières étant les plus proches de la portion plate 12.This sleeve cooperates with the cable 14 like the sleeve 1, the smaller diameter portions of the gutters being closest to the flat portion 12.
Dans un autre mode de réalisation représenté en figure 18, le manchon 201 est similaire au manchon 101 si ce n'est que la languette à bords parallèle 104 est remplacée par une languette 204 à bords inclinés l'un vers l'autre présentant ainsi une forme générale trapézoïdale lorsque le manchon 201 est dans sa position de repos. La languette 204 permet de rattraper le décalage longitudinal dû à la forme tronconique des gouttières et facilite ainsi l'ajustement deux à deux des bosses 206 de la gouttière 202 avec les bosses 206 correspondantes de la gouttière 203 et des creux 205 de la gouttière 202 avec les creux 205 correspondants de la gouttière 203.In another embodiment shown in FIG. 18, the sleeve 201 is similar to the sleeve 101 except that the tongue with edges parallel 104 is replaced by a tongue 204 with edges inclined towards one another and thus having a generally trapezoidal shape when the sleeve 201 is in its rest position. The tab 204 makes it possible to make up the longitudinal offset due to the frustoconical shape of the gutters and thus facilitates the two-to-two adjustment of the bumps 206 of the gutter 202 with the corresponding bumps 206 of the gutter 203 and the depressions 205 of the gutter 202 with the corresponding hollows 205 of the gutter 203.
Dans encore un autre mode de réalisation représenté en figure 19, les ondulations présentent une amplitude variable, l'écart qui sépare le fond d'un creux (305A, 305B, 305C) du sommet d'une bosse (306A, 306B, 306C) variant régulièrement d'une ondulation à l'autre (dégressivement dans l'exemple illustré) pour également faciliter l'opération d'extraction du manchon hors du moule de fabrication. En réduisant l'amplitude des ondulations pour la zone du manchon située au plus profond du moule (l'ondulation constituée du creux 305 C et de la bosse 306 C dans l'exemple illustré) les risques de mettre en butée le manchon contre les portions saillantes du moule lors de l'extraction sont limités.In yet another embodiment shown in FIG. 19, the corrugations have a variable amplitude, the gap separating the bottom of a recess (305A, 305B, 305C) from the top of a boss (306A, 306B, 306C) varying regularly from one corrugation to another (degressively in the example shown) to also facilitate the extraction operation of the sleeve out of the manufacturing mold. By reducing the amplitude of the corrugations for the zone of the sleeve located in the deepest part of the mold (the corrugation formed by the depression 305 C and the hump 306 C in the illustrated example), the risks of abutting the sleeve against the portions protruding from the mold during extraction are limited.
Dans des variantes non illustrées les nervurages sont des nervures rapportées sur la paroi des gouttières ou résultent d'une surépaisseur locale de la matière. Dans une autre variante non illustrée la languette souple du manchon présente une forme légèrement bombée au repos et/ou présente une épaisseur plus importante que celle des gouttières.In non-illustrated variants, the ribs are ribs attached to the wall of the gutters or result from a local extra thickness of the material. In another variant not shown, the flexible tongue of the sleeve has a slightly convex shape at rest and / or has a greater thickness than the gutters.
Dans une autre variante le manchon moulé appartient à la famille desIn another variant, the molded sleeve belongs to the family of
PVC. Dans encore une autre variante le manchon est d'une seule pièce en thermoplastique extrudé, par exemple en polyamide ou en PVC.PVC. In yet another variant the sleeve is a single piece of extruded thermoplastic, for example polyamide or PVC.
Dans une autre variante encore les deux gouttières ne sont pas image miroir l'une de l'autre et présentent des dimensions différentes l'une de l'autre.In another variant, the two gutters are not mirror image of each other and have different dimensions from each other.
Les différents manchons décrits sont également adaptés pour isoler électriquement des éléments électriques autres que des cosses, des portions dénudées de conducteur électrique ou des barreaux d'alimentation électrique par exemple. Dans d'autres modes de réalisation le manchon est coloré afin d'identifier et de repérer le câble qu'il entoure, sans être nécessairement en matière isolante.The different sleeves described are also adapted to electrically isolate electrical elements other than lugs, stripped portions of electrical conductor or power supply bars for example. In other embodiments, the sleeve is colored in order to identify and locate the cable that it surrounds, without necessarily being of insulating material.
La présente invention n'est pas limitée aux modes de réalisation décrits et représentés mais englobe toute variante d'exécution. The present invention is not limited to the embodiments described and shown but encompasses any variant embodiment.
