Abstract

The easily strippable electrical cable comprises insulated conductors and a sheath surrounding them and having at least one longitudinal rib and at least one longitudinal groove, forming between them at least one set of associated elements for the stripping operation. It is characterised in that each external rib (10, 11, 12, 13) has a cross-section of substantially radial axis in the thickness of the sheath (4) and constitutes an initiator for fracture of the sheath, and in that each set of associated elements is formed by a pair of two first elements (10-11, 12-13) of the same type and by a third element (14, 15) of the other type, centred between the two first ones, making it possible to catch and pull on the sheath and to cause it to tear longitudinally. Application: telecommunication cable.

Description

Câble électrique aisément dépainable
La présente invention porte sur un câble électrique aisément dégainable, sans outil spécial adapté à cet effet, comportant des conducteurs isolés individuellement et une gaine extérieure les entourant.Easily stripped electrical cable
The present invention relates to an easily unsheathable electrical cable, without a special tool suitable for this purpose, comprising individually insulated conductors and an outer sheath surrounding them.

Le document FR-A-2 645 358 décrit un câble électrique qui peut comporter en outre de possibles drains, entre les conducteurs isolés et la gaine et qui est dégainable à l'aide d'une pince spéciale adaptée de coupe en évitant de blesser les conducteurs. A cet effet, la gaine présente deux couples de nervures délimitant quatre rainures longitudinales se faisant face deux à deux dans deux plans parallèles de coupe, chacun de ces plans coupant la surface intérieure de la gaine mais restant extérieur aux conducteurs et aux possibles drains. Chaque nervure est attenante à l'une des nervures, ainsi directement délimitée et définie. La gaine munie de ses deux couples de nervures et de rainures est de section s'inscrivant dans un carré. The document FR-A-2 645 358 describes an electric cable which may also include possible drains, between the insulated conductors and the sheath and which can be stripped using a special suitable cutting pliers avoiding injury to the conductors. To this end, the sheath has two pairs of ribs delimiting four longitudinal grooves facing two by two in two parallel cutting planes, each of these planes cutting the inner surface of the sheath but remaining outside the conductors and possible drains. Each rib is attached to one of the ribs, thus directly delimited and defined. The sheath provided with its two pairs of ribs and grooves is of section inscribed in a square.

La pince adaptée de dégainage de ce câble est à deux mâchoires articulées reçues dans les rainures d'un même couple et actionnées pour couper la gaine selon le plan de coupe précité. Elle permet avec les couples de nervures et de rainures définis sur la gaine de minimiser les risques de blessure des conducteurs. The suitable pliers for stripping this cable has two articulated jaws received in the grooves of the same torque and actuated to cut the sheath according to the aforementioned cutting plane. It allows with the pairs of ribs and grooves defined on the sheath to minimize the risk of injury to the conductors.

La présente invention a pour but de rendre un câble électrique dégainable aisément, ceci sans un tel outil spécial adapté de coupe ou un quelconque autre outil spécial. The object of the present invention is to make an electrical cable easily unsheathable, this without such a special suitable cutting tool or any other special tool.

Elle a pour objet un câble électrique aisément dégainable, sans outil spécial de dégainage, comportant des conducteurs isolés et une gaine les entourant et présentant extérieurement au moins une nervure longitudinale et au moins une rainure longitudinale en formant entre elles au moins un jeu d'éléments associés de deux types différents pour le dégainage caractérisé en ce que chaque rainure extérieure est de section d'axe sensiblement radial dans l'épaisseur de la gaine, pour constituer une amorce de rupture sur la gaine, et en ce que chaque jeu d'éléments associés est constitué d'un couple de deux premiers éléments de l'un des deux types et d'un troisième élément de l'autre type sensiblement centré entre les deux premiers, pour permettre de saisir et tirer sur la gaine et ainsi de provoquer sa déchirure longitudinalement. It relates to an easily unsheathable electrical cable, without special stripping tool, comprising insulated conductors and a sheath surrounding them and having externally at least one longitudinal rib and at least one longitudinal groove forming between them at least one set of elements associated with two different types for stripping, characterized in that each external groove has a section of substantially radial axis in the thickness of the sheath, to constitute a starting point for rupture on the sheath, and in that each set of elements associated consists of a pair of first two elements of one of the two types and a third element of the other type substantially centered between the first two, to allow to grasp and pull on the sheath and thus cause its tear longitudinally.

Elle présente en outre avantageusement au moins l'une des caractérisques additionnelles suivantes: - les éléments associés de chaque jeu sont non jointifs - la gaine comporte en outre des rainures intérieures supplémentaires en regard des rainures extérieures. It also advantageously has at least one of the following additional characteristics: - the associated elements of each set are non-contiguous - the sheath also has additional internal grooves opposite the external grooves.

- la gaine pourvue desdites rainures et nervures est extrudée.- The sheath provided with said grooves and ribs is extruded.

Les caractéristiques et avantages de la présente invention ressortiront de la description faite ci-après en regard des dessins ci-annexés. Dans ces dessins
La figure 1 représente en coupe un câble électrique selon l'invention.The characteristics and advantages of the present invention will emerge from the description given below with reference to the attached drawings. In these drawings
Figure 1 shows in section an electric cable according to the invention.

La figure 2 montre en coupe une variante de réalisation. Figure 2 shows in section an alternative embodiment.

En regard des figures 1 et 2, on voit que ce câble comporte des conducteurs isolés 1, 2 et 3 et une gaine 4 entourant les conducteurs isolés. L'isolation individuelle des conducteurs est notée 5, 6 ou 7 selon le conducteur considéré. With reference to FIGS. 1 and 2, it can be seen that this cable has insulated conductors 1, 2 and 3 and a sheath 4 surrounding the insulated conductors. The individual insulation of the conductors is noted 5, 6 or 7 depending on the conductor considered.

Dans la figure 1, la gaine 4 présente deux couples de rainures longitudinales extérieures 10-11 et 12 -13 dans l'épaisseur de la gaine rendue réduite à leur niveau, qui constituent des amorces de rupture de la gaine. Ces rainures sont de préférence de section en Vé, dont l'axe médian est radial sur le câble. Les deux couples de rainures sont opposés l'un à l'autre. De préférence, deux rainures d'un même couple sont séparées par un secteur d'angle compris entre 90" et 30 .  In FIG. 1, the sheath 4 has two pairs of external longitudinal grooves 10-11 and 12 -13 in the thickness of the sheath made reduced to their level, which constitute primers for breaking the sheath. These grooves are preferably of V-shaped section, the median axis of which is radial on the cable. The two pairs of grooves are opposite to each other. Preferably, two grooves of the same couple are separated by an angle sector between 90 "and 30.

La gaine comporte en outre deux nervures longitudinales extérieures 14 et 15, opposées et centrées entre les deux rainures de l'un et de l'autre des couples de rainures. The sheath further comprises two external longitudinal ribs 14 and 15, opposite and centered between the two grooves of one and the other of the pairs of grooves.

Chacune de ces nervures définit un épaulement de relativement faible largeur, qui permet de saisir et tirer sur la gaine, ainsi que symbolisé par les flèches 14A et 15A pour son ouverture au niveau des deux rainures de part et d'autre.Each of these ribs defines a shoulder of relatively small width, which makes it possible to grasp and pull on the sheath, as symbolized by the arrows 14A and 15A for its opening at the level of the two grooves on either side.

Elle est non jointive avec les deux rainures entre lesquelles elle est centrée.It is not joined with the two grooves between which it is centered.

La gaine comporte avantageusement en outre deux couples de rainures longitudinales intérieures 20 - 21 et 22 - 23, ces rainures sont en regard des rainures extérieures et de préférence comme elles de section en Vé, pour faciiiter la déchirure de la gaine. The sheath advantageously further comprises two pairs of internal longitudinal grooves 20 - 21 and 22 - 23, these grooves are opposite the external grooves and preferably like them of V-shaped section, to facilitate tearing of the sheath.

Sur cette même figure 1 on a illustré l'opération de dégainage. En tirant selon les flèches 14A et 15B on provoque directement la déchirure locale de la gaine au niveau des rainures. Les deux portions 17, 18 de gaine situées entre les deux rainures deux couples sont alors désolidarisées longitudinalement des autres parties de la gaine, sur la longueur souhaitée, ainsi que schématisé en pointillés en 17' et 18'. Elles sont ensuite coupées transversalement, à l'aide d'une paire de ciseaux ou d'une pince coupante. Les parties restantes de la gaine sont pareillement écartées des conducteurs isolés et coupées transversalement. In this same figure 1 is illustrated the stripping operation. By pulling according to arrows 14A and 15B, the local sheath of the sheath is directly caused at the level of the grooves. The two sheath portions 17, 18 situated between the two grooves two pairs are then separated longitudinally from the other parts of the sheath, over the desired length, as shown diagrammatically in dotted lines at 17 'and 18'. They are then cut transversely, using a pair of scissors or wire cutters. The remaining parts of the sheath are likewise separated from the insulated conductors and cut transversely.

Dans la figure 2, la gaine 4 présente trois rainures longitudinales extérieures 30, 31 et 32 et trois couples de nervures 33 - 34, 35-36 et 37 - 38, chaque couple de nervures étant associé à l'une de ces rainures et ses deux nervures situées de part et d'autre de la rainure concernée en étant relativement proches d'elle. Elle présente aussi avantageusement en outre trois rainures intérieures 40, 41 et 42, en vis-à-vis des rainures extérieures. Ces rainures extérieures et intérieures sont de section en Vé, dont l'axe est sensiblement radial dans l'épaisseur de la gaine, et constituent des amorces de rupture de la gaine. In FIG. 2, the sheath 4 has three external longitudinal grooves 30, 31 and 32 and three pairs of ribs 33 - 34, 35-36 and 37 - 38, each pair of ribs being associated with one of these grooves and its two ribs located on either side of the groove concerned while being relatively close to it. It also advantageously also has three internal grooves 40, 41 and 42, facing the external grooves. These exterior and interior grooves are of V-shaped section, the axis of which is substantially radial in the thickness of the sheath, and constitute primers for breaking the sheath.

De préférence, les nervures d'un même couple sont séparées par un secteur angulaire de l'ordre de 60 .  Preferably, the ribs of the same pair are separated by an angular sector of the order of 60.

En variante non illustrée, la gaine présente deux rainures extérieures opposées, deux rainures intérieures en vis-à-vis des rainures extérieures et deux couples de nervures, chacun de ces couples de nervures étant associé à l'une des rainures extérieures. In a variant not illustrated, the sheath has two opposite external grooves, two internal grooves facing the external grooves and two pairs of ribs, each of these pairs of ribs being associated with one of the external grooves.

En tirant sur les deux nervures de l'un des couples, on provoque la déchirure de la gaine au niveau de la rainure entre elles. On peut ainsi séparer longitudinalement les parties de la gaine des conducteurs et les couper transversalement. By pulling on the two ribs of one of the pairs, the sheath is torn at the level of the groove between them. It is thus possible to separate the parts of the sheath of the conductors longitudinally and cut them transversely.

La gaine 4 selon la figure 1 ou 2 de ses rainures et nervures est ainsi directement extrudée, la filière d'extrusion étant simplement prévue en conséquence. Cette filière peut être elle-même à éléments escamotables pour la formation possible en discontinu des rainures et des nervures sur la gaine extrudée. The sheath 4 according to Figure 1 or 2 of its grooves and ribs is thus directly extruded, the extrusion die being simply provided accordingly. This die can itself be with retractable elements for the possible discontinuous formation of grooves and ribs on the extruded sheath.

Un tel câble est en particulier un câble de télécommunication à nombre quelconque de conducteurs isolés. Such a cable is in particular a telecommunications cable with any number of insulated conductors.

I1 est réalisé et posé de manière classique, sans nécessiter de protections particulières. I1 est d'aspect banal, et en particulier de section restant globalement circulaire sur laquelle les nervures sont simplement légèrement saillantes. I1 is produced and installed in a conventional manner, without requiring any special protection. I1 is of ordinary appearance, and in particular of section remaining generally circular on which the ribs are simply slightly protruding.

I1 permet un dégainage sans outil de coupe de dégainage et donc sans risque de blesser les conducteurs. Ce dégainage est rapide et aisé et permet d'accéder à souhait aux conducteurs isolés du câble, en particulier pour leur raccordement sur des contacts auto-dénudants d'équipement. Bien entendu le nombre de rainures peut être quelconque, en restant toutefois relativement limité, avec chaque rainure extérieure et un couple de nervures ou chaque couple de rainures extérieures et une nervure définissant entre eux un jeu de trois éléments associés pour le dégainage sans outil spécial.  I1 allows stripping without a stripping cutting tool and therefore without risk of injuring the conductors. This stripping is quick and easy and allows access to the insulated conductors of the cable as desired, in particular for their connection to self-stripping equipment contacts. Of course the number of grooves can be any, while remaining relatively limited, with each outer groove and a pair of ribs or each pair of outer grooves and a rib defining between them a set of three associated elements for stripping without special tools.
