Abstract
Description
La présente invention concerne un dispositif pour constituer une attache à l'extrémité d'un câble à enveloppe plastique (type électrique ou téléphonique). The present invention relates to a device for forming a fastener at the end of a cable with a plastic envelope (electrical or telephone type).
Cette attache a pour fonction de permettre une liaison solide entre un câble et une épingle de tirage située dans un conduit ou une gaine.The purpose of this fastener is to allow a solid connection between a cable and a pulling pin located in a conduit or a sheath.
L'attache de tirage des câbles est traditionnel -lement réalisée avec les fils du câble, libérés après dénudage puis enrubannés avec du ruban adhésif pour former une boucle ensuite reliée à l'épingle de tirage. The cable pulling attachment is traditional - only made with the wires of the cable, released after stripping and then wrapped with adhesive tape to form a loop then connected to the pulling pin.
Il est à noter que nombres de ces fils sont enduits d'une substance grasse anti-humidité rendant la liaison du ruban adhésif avec les fils peu efficace. It should be noted that many of these wires are coated with a fatty anti-humidity substance which makes the bonding of the adhesive tape with the wires ineffective.
On sait aussi que de nombreux conduits offrent une importante résistance au frottement (due à leur longueur ou leur tracé) rendant l'effort de tirage du câble supérieur à la résistance de l'attache.We also know that many conduits offer a high resistance to friction (due to their length or their layout) making the cable pulling force greater than the resistance of the fastener.
Cela se traduit en pratique par de nombreuses ruptures de la liaison cable-épingle lors du tirage du câble dans son conduit. Seul un câble de gros diamètre (supérieur à 20 mm) peut-être percé et boulonné transversalement pour créer une attache solide mais volumineuse. In practice, this results in numerous breaks in the cable-pin connection when the cable is pulled through its conduit. Only a large diameter cable (greater than 20 mm) can be drilled and bolted transversely to create a solid but bulky connection.
L'invention vise à pallier ces inconvénients en proposant un moyen d'attache composé d'une douille métallique à sertir en forme de tube cylindrique dont le diamètre intérieur correspond au diamètre au câble et dans laquelle on glisse l'extrémité du câble afin d'effectuer un sertissage
Cette douille reçoit alors un sertissage spécifique pour la rendre solidaire du câble, créant un moyen d'attache efficace ne nécessitant ni dénudage, ni emploi de ruban adhésif.The invention aims to overcome these drawbacks by proposing a fastening means composed of a metal socket to be crimped in the form of a cylindrical tube whose internal diameter corresponds to the diameter of the cable and in which the end of the cable is slid in order to crimp
This socket then receives a specific crimp to make it integral with the cable, creating an effective attachment means requiring neither stripping nor the use of adhesive tape.
L'invention vise ainsi à proposer une douille à sertir avec laquelle la réalisation d'un moyen d'attache sur le câble devient une opération simple et rapide en utilisant une pince manuelle munie d'un poinçon de sertissage taillant. The invention thus aims to propose a crimping socket with which the production of an attachment means on the cable becomes a simple and rapid operation using manual pliers provided with a cutting crimping punch.
Des caractéristiques et avantages apparaîtront à la lecture de la description suivante qui se réfère aux figures annexées dans lesquelles
-la figure 1 est une vue schématique en coupe partielle de la douille selon l'invention.Characteristics and advantages will appear on reading the following description which refers to the appended figures in which
FIG. 1 is a schematic view in partial section of the socket according to the invention.
-la figure 2 et la figure 3 sont des vues en coupe partielle illustrant respectivement une deuxième et une troisième variante de l'invention. FIG. 2 and FIG. 3 are views in partial section respectively illustrating a second and a third variant of the invention.
-la figure 4 est une vue schématique en coupe partielle de la douille une fois sertie selon l'invention. FIG. 4 is a schematic view in partial section of the socket once crimped according to the invention.
-la figure 5 est une vue schématique d'un outil de sertissage concernant l'invention. FIG. 5 is a schematic view of a crimping tool relating to the invention.
-la figure 6 est une vue schématique du poinçon pénétrant la douille selon l'invention. FIG. 6 is a schematic view of the punch penetrating the socket according to the invention.
L'invention concerne une douille (1), glissée sur un câble (4), sur laquelle on applique une déchirure partielle à l'aide d'une pince (5) munie d'un poinçon (6) provocant une saillie (3) qui pénètre dans la matière du câble. The invention relates to a sleeve (1), slipped on a cable (4), to which a partial tear is applied using pliers (5) provided with a punch (6) causing a projection (3) which penetrates the material of the cable.
Cette saillie (3) orientée vers l'avant et inclinée vers le coeur du câble, fait office d'une griffe plantée dans la matière, retenant le câble dans la douille (1). Suivant la taille de la douille, on appliquera deux ou plusieurs saillies (3) donnant ainsi une liaison très résistante en traction. This projection (3) oriented forward and inclined towards the heart of the cable, acts as a claw planted in the material, retaining the cable in the socket (1). Depending on the size of the socket, two or more projections (3) will be applied, thus giving a very resistant connection in traction.
L'invention est également caractérisée par un moyen de fixation (2) ayant pour rôle de relier l'épingle de tirage à la douille (1). The invention is also characterized by a fixing means (2) having the role of connecting the pulling pin to the socket (1).
Selon les modes particuliers de réalisation, la douille est prolongée par un moyen de fixation (2) constitué préférentiellement d'un taraudage ou d'une extrémité filetée ou d'un simple perçage perpendiculaire. According to the particular embodiments, the sleeve is extended by a fixing means (2) preferably consisting of a thread or a threaded end or a simple perpendicular drilling.
L'invention est aussi caractérisée par une douille (l) dont l'épaisseur de l'envelloppe cylindrique acceuill -ant le câble est telle qu'elle puisse être perforée facilement. The invention is also characterized by a sleeve (l) whose thickness of the cylindrical envelope accommodating the cable is such that it can be perforated easily.
Le dispositif selon l'invention est particulièrement facile à mettre en oeuvre grâce à une simple pince (5) munie d'un poinçon (6) qui pénètre la douille pour former une saillie (3). A titre d'exemple non limitatif, le poinçon (6) a une forme conique partiellement coupée selon son axe vertical, formant un plat à arrêtes taillantes. The device according to the invention is particularly easy to implement thanks to a simple clamp (5) provided with a punch (6) which penetrates the sleeve to form a projection (3). By way of nonlimiting example, the punch (6) has a conical shape partially cut along its vertical axis, forming a flat with cutting edges.
L'invention est aussi caractérisée par une douille (1) dont le diamètre extérieur ne diffère que très peu du diamètre du câble (4), optimisant ainsi sa capacité de passage dans un conduit. The invention is also characterized by a socket (1) whose outside diameter differs very little from the diameter of the cable (4), thus optimizing its capacity for passage through a conduit.
La douille selon l'invention comporte en outre avantageusement un chanfrein circulaire en son extrémité (coté taraudage), évitant ainsi les risques d'accroche dans le conduit ou la gaine. The socket according to the invention also advantageously comprises a circular chamfer at its end (tapping side), thus avoiding the risks of catching in the conduit or the sheath.
L'invention vise aussi à proposer une douille de conception simple et peu onéreuse à usage aisé qui une fois utilisée sera éliminée en coupant le câble. The invention also aims to propose a socket of simple and inexpensive design for easy use which, once used, will be eliminated by cutting the cable.
L'invention vise également à proposer un moyen de sertissage de la douille caractérisé par une pince manuelle de conception simple, fiable, à usage aisé et utilisable en tout lieu. The invention also aims to provide a means of crimping the sleeve characterized by a manual pliers of simple, reliable design, easy to use and usable in any place.
