Description
Cassette notamment pour fibres optiques ou fils conducteursCassette especially for optical fibers or conductive wires
La présente invention se rapporte aux cassettes et, tout particulièrement, aux cassettes destinées à recevoir des conducteurs. Dans le présent mémoire, on entend par conducteurs aussi bien des éléments filiformes ou en forme de bande, dans lesquels de la lumière peut se propager, que des éléments filiformes ou en forme de bande conducteurs de l'électricité, notamment des fils métalliques, par exemple en cuivre, ou des fils de cuivre téléphoniques.The present invention relates to cassettes and, more particularly, to cassettes intended to receive conductors. In the present specification, the term “conductors” means both filiform or strip-shaped elements in which light can propagate, as filiform or strip-shaped elements conducting electricity, in particular metallic wires, by for example copper, or telephone copper wires.
L'organisation des fibres optiques dans un contenant exige un système de cassettes ou de plateaux qui permet de ranger les fibres optiques, de respecter les contraintes de rayons de courbure minimum et de faciliter les interventions sur les fibres. Les cassettes existantes sont dans l'ensemble destinées à permettre un certain nombre de raccordements simples de fibres (une fibre en entrée raccordée à une fibre en sortie). Ces raccordements sont logés dans une même face de la cassette ou du plateau. (DE-A-4 438 668, DE-U-84 1 1 159 et DE-U-297 22 349).The organization of the optical fibers in a container requires a system of cassettes or trays which makes it possible to store the optical fibers, to respect the constraints of minimum radii of curvature and to facilitate interventions on the fibers. The existing cassettes are generally intended to allow a certain number of simple fiber connections (an input fiber connected to an output fiber). These connections are housed on the same side of the cassette or tray. (DE-A-4 438 668, DE-U-84 1 1 159 and DE-U-297 22 349).
L'invention vise une cassette qui, à même encombrement, peut recevoir davantage de conducteurs et qui, pour la réception d'une longueur donnée de conducteurs, nécessite moins de pièces et moins de place. En outre, la cassette suivant l'invention permet de séparer les conducteurs par application et d'utiliser des types différents de connecteurs. On cherche notamment à séparer le lovage des surlongueurs des raccordements.The invention relates to a cassette which, with the same size, can receive more conductors and which, for the reception of a given length of conductors, requires fewer parts and less space. In addition, the cassette according to the invention makes it possible to separate the conductors by application and to use different types of connectors. One seeks in particular to separate the coiling of the extra lengths of the connections.
L'invention a donc pour objet une cassette comprenant un corps et un premier couvercle ayant au moins deux passages de communication avec l'extérieur. Le fond du corps est à distance de la partie frontale du premier couvercle et est muni, sur sa première face en regard du premier couvercle,
d'un premier chicanage de définition d'un trajet Suivant l'invention, le fond est à distance de la partie frontale d'un second couvercle et est muni d'un second chicanage sur sa seconde face en regard de la partie frontale du second couvercle On utilise ainsi les deux faces du fond, qui est notamment a mi- hauteur, pour prévoir sur chacune d'entre elles un chicanage de définition d'un trajet pour des conducteurs. On obtient ainsi un avantage économique une cassette (une seule pièce, un seul cycle de production, un seul conditionnement ..etc), mais avec le double de surface de rangement pour les fibres, des avantages ergonomiques la possibilité de séparer les fibres par application en les rangeant dans des faces différentes (une face pour client A, une face pour client B), - l'utilisation d'une face pour les raccordements et de l'autre pour le lovage des surlongueurs. Une intervention sur celle-ci ne porte pas atteinte aux communications, la possibilité d'utiliser différents types de connecteurs (ex thermorétractable sur une face, raccord mécanique sur la seconde- il est difficile de faire un panachage des deux types sur une même face)The invention therefore relates to a cassette comprising a body and a first cover having at least two communication passages with the outside. The bottom of the body is spaced from the front part of the first cover and is provided, on its first face facing the first cover, of a first baffle for defining a path According to the invention, the bottom is spaced from the front part of a second cover and is provided with a second baffle on its second face opposite the front part of the second cover The two faces of the bottom, which is in particular at mid-height, are thus used to provide on each of them a baffle for defining a path for conductors. An economic advantage is thus obtained for a cassette (a single piece, a single production cycle, a single packaging, etc.), but with twice the storage surface for the fibers, ergonomic advantages the possibility of separating the fibers by application by storing them in different sides (one side for client A, one side for client B), - the use of one side for the connections and the other for the coiling of the extra lengths. An intervention on it does not affect communications, the possibility of using different types of connectors (eg heat shrink on one side, mechanical connection on the second - it is difficult to mix the two types on the same side)
Le chicanage est le plus souvent tel qu'il définit un trajet dont le rayon de courbure est en tout point supérieure au rayon minimum admissible pour le conducteur, par exemple a 25 mm, de manière à prévenir tout pliage intempestif des conducteurs Suivant un mode de réalisation tout particulièrement préfère, le fond comporte un trou traversant en un point du trajet On peut ainsi faire passer les conducteurs d'une face a l'autre du fond De préférence, ce trou traversant est au bord du fond et avantageusement, il est prévu plusieurs trous traversants Pour fixer la cassette, le corps comporte habituellement une patte de fixation en saillie et il est prévu également habituellement un moyen de fixation d'un conducteur dans chaque passage et un organe de maintien des conducteurs sur le trajet défini par le chicanage La cassette peut avoir une face latérale s'etendant de part et d'autre du fond, au moins sur trois de ses côtés, à l'exclusion du côte comportant les pattes de fixation
Au dessin annexé, donné uniquement à titre d'exemple : la figure 1 est une vue en perspective du fond d'une cassette suivant l'invention, et la figure 2 est une vue à plus petite échelle de l'un des couvercles. La cassette en matière plastique comporte un corps et deux couvercles opposés.The baffling is most often such that it defines a path whose radius of curvature is at any point greater than the minimum radius allowable for the conductor, for example at 25 mm, so as to prevent any untimely bending of the conductors According to a mode of a particularly preferred embodiment, the bottom has a through hole at a point in the path. It is thus possible to pass the conductors from one face to the other of the bottom. Preferably, this through hole is at the edge of the bottom and, advantageously, it is provided several through holes To fix the cassette, the body usually comprises a projecting fixing lug and there is also usually provided a means of fixing a conductor in each passage and a member for holding the conductors on the path defined by the baffling La cassette may have a lateral face extending on either side of the bottom, at least on three of its sides, excluding the rib comprising the tabs fixation In the accompanying drawing, given only by way of example: FIG. 1 is a perspective view of the bottom of a cassette according to the invention, and FIG. 2 is a view on a smaller scale of one of the covers. The plastic cassette has a body and two opposite covers.
Le corps est constitué d'un fond 1 de forme sensiblement rectangulaire, si ce n'est que l'un des petits côtés est incurvé en tournant sa convexité vers l'extérieur. Sur chaque face du fond sont ménagés des chicanages de définition d'un trajet pour une fibre optique. Sur le petit côté rectiligne du fond sont ménagés deux passages 3 de communication avec l'extérieur. Le faisceau de fibres optiques peut entrer par l'un de ces passages dans la cassette et ressortir par l'autre. Ces passages comportent un moyen de fixation 4 d'un conducteur. En l'espèce, les moyens de fixation sont constitués par le fait que la face 5 latérale de la cassette comporte, à l'extrémité proche du petit côté rectiligne, des fentes 6 et que des trous 7 correspondants sont ménagés dans le fond 1 , de sorte qu'un collier passant dans ces fentes 6 et trous 7 peut serrer les fibres optiques qui passent dans le passage 4. La face 5 latérale s'étend de part et d'autre du fond 1. Sur le bord du fond 1 et sur le trajet défini par les chicanages 2 sont ménagés quatre échancrures 8 formant des trous traversants qui permettent aux conducteurs de passer d'une face du fond 1 à l'autre.The body consists of a bottom 1 of substantially rectangular shape, except that one of the short sides is curved by turning its convexity towards the outside. On each face of the bottom are baffles defining a path for an optical fiber. On the small rectilinear side of the bottom are formed two passages 3 for communication with the outside. The bundle of optical fibers can enter through one of these passages in the cassette and exit through the other. These passages include a means 4 for fixing a conductor. In this case, the fixing means are constituted by the fact that the lateral face 5 of the cassette comprises, at the end close to the small straight side, slots 6 and that corresponding holes 7 are formed in the bottom 1, so that a collar passing through these slots 6 and holes 7 can clamp the optical fibers which pass through the passage 4. The side face 5 extends on either side of the bottom 1. On the edge of the bottom 1 and on the path defined by the baffles 2 are formed four notches 8 forming through holes which allow the conductors to pass from one face of the bottom 1 to the other.
Du petit côté du fond font saillies deux pattes 9 de fixation de la cassette. Il est prévu également sur le fond 1 des mâchoires 10 de fixation d'une épissure.On the small side of the bottom protrude two tabs 9 for fixing the cassette. There is also provided on the bottom 1 of the jaws 10 for fixing a splice.
La cassette comporte en outre des moyens 11 de maintien d'un conducteur sur le trajet défini par le chicanage 2.The cassette also comprises means 11 for holding a conductor on the path defined by the baffling 2.
La figure 2 montre l'un des couvercles qui comporte une partie frontale 12 qui est destinée à venir en regard de l'une des faces du fond 1 , la partie frontale d'un autre couvercle identique venant en regard de l'autre face du fond 1. Chaque couvercle comporte des moyens 13 d'encliquetage qui viennent s'encliqueter dans des trous 14 d'encliquetage correspondants ménagés sur la face 5 latérale du corps de la cassette.
FIG. 2 shows one of the covers which has a front part 12 which is intended to come opposite one of the faces of the bottom 1, the front part of another identical cover coming opposite the other face of the bottom 1. Each cover has latching means 13 which snap into corresponding latching holes 14 formed on the side face 5 of the body of the cassette.
