Description

La présente invention concerne le domaine du câblage des circuits électroniques et électriques au moyen de câbles plats, et a pour objet une machine à dénuder de tels câbles. The present invention relates to the field of wiring electronic and electrical circuits by means of flat cables, and relates to a machine for stripping such cables.

Actuellement, les câbles plats, principalement utilisés avec des circuits imprimés, sont généralement reliés auxdits circuits au moyen de connecteurs enfichés sur les câbles et soudés sur les circuits. Ce mode de réalisation des liaisons, du fait de la nécessité de disposer de connecteurs, est cependant relativement coûteux. Currently, flat cables, mainly used with printed circuits, are generally connected to said circuits by means of connectors plugged into the cables and soldered to the circuits. This embodiment of the connections, due to the need to have connectors, is however relatively expensive.

La présente invention a pour but de pallier cet inconvénient. The object of the present invention is to overcome this drawback.

Elle a, en effet, pour objet une machine à dénuder des câbles plats, caractérisée en ce qu'elle est essentiellement constituée par un dispositif d'introduction et de guidage du câble fixé sur un bâti et muni d'un guide fixe et d'un guide mobile verticalement at chargé par un ressort de pression, par un dispositif de serrage du câble sur le guide fixe comprenant un marteau actionné par un vérin, par un ensemble de coupe de la gaine monté déplaçable en translation sur le bâti et pourvu d'un couteau inférieur fixe, d'un couteau supérieur mobile sous l'action d'un vérin, et d'une butée de fin de course règlable, et par un vérin de déplacement de l'ensemble de coupe. It has, in effect, a machine for stripping flat cables, characterized in that it is essentially constituted by a device for introducing and guiding the cable fixed on a frame and provided with a fixed guide and a vertically movable guide at loaded by a pressure spring, by a cable clamping device on the fixed guide comprising a hammer actuated by a jack, by a sheath cutting assembly mounted movable in translation on the frame and provided with a fixed lower knife, a movable upper knife under the action of a jack, and an adjustable end stop, and by a jack for moving the cutting assembly.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence au dessin schématique annexé, dont la figure unique est une vue en élévation frontale d'une machine conforme à l'invention. The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawing, the single figure of which is a view in front elevation of a machine according to the invention.

La machine à dénuder des câbles plats représentée au dessin annexé est constituée par un bâti 1 sur lequel est monté un dispositif 2 d'introduction et de guidage du câble 3, par un dispositif 4 de serrage du câble 3, par un ensemble 5 de coupe de la gaine, et par un vérin 6 de déplacement de l'ensemble 5. The stripping machine for flat cables shown in the appended drawing consists of a frame 1 on which is mounted a device 2 for introducing and guiding the cable 3, by a device 4 for clamping the cable 3, by a cutting assembly 5 of the sheath, and by a jack 6 for moving the assembly 5.

Le dispositif 2 d'introduction et de guidage du câble 3 est constitué par un guide fixe 7 solidaire du bâti 1, muni d'encoches de guidage des fils, et par un guide 8 mobile verticalement également muni d'encoches, et chargé par un ressort de pression 9. Grâce à ce mode de réalisation, l'introduction du câble s'effectue de manière très précise en direction de l'ensemble de coupe 5. The device 2 for introducing and guiding the cable 3 is constituted by a fixed guide 7 secured to the frame 1, provided with notches for guiding the wires, and by a guide 8 movable vertically also provided with notches, and loaded by a pressure spring 9. Thanks to this embodiment, the cable is introduced very precisely in the direction of the cutting assembly 5.

Ce dernier est monté au moyen de glissières 10 sur le bâti 1 et est déplaçable sur ce dernier grâce au vérin 6, et il est constitué par un couteau inférieur fixe 11 et par un couteau supérieur 12 mobile verticalement sous l'action d'un vérin 13. Le guidage du couteau supérieur mobile 12 est réalisé grâce à deux montants 14 solidaires du support 15 du couteau 11, et reliés entre eux par une traverse 16 portant le vérin 13. Le support 15 est relié au vérin 6 et porte une butée de fin de course 17 règlable en position au moyen d'une vis 18 et permettant de règler la longueur à dénuder. The latter is mounted by means of slides 10 on the frame 1 and is movable on the latter thanks to the jack 6, and it is constituted by a fixed lower knife 11 and by an upper knife 12 movable vertically under the action of a jack 13. The guiding of the movable upper knife 12 is carried out by means of two uprights 14 integral with the support 15 of the knife 11, and connected together by a cross member 16 carrying the jack 13. The support 15 is connected to the jack 6 and carries a stop limit switch 17 adjustable in position by means of a screw 18 and making it possible to adjust the length to be stripped.

Les couteaux 11 et 12 présentent avantageusement des encoches coupantes, dont le rayon correspond à celui des fils du câble 3, et leur partie plane est tournée vers la partie à dénuder. The knives 11 and 12 advantageously have cutting notches, the radius of which corresponds to that of the wires of the cable 3, and their flat part is turned towards the part to be stripped.

Le dispositif 4 de serrage du câble 3 est constitué par un marteau 19 actionné par un vérin 20 et seraant, en position de service, le câble 3 sur le guide fixe 7. The device 4 for tightening the cable 3 is constituted by a hammer 19 actuated by a jack 20 and, in the service position, the cable 3 on the fixed guide 7.

Derrière le couteau fixe 11 est prévu, en outre, un évidement 21 permettant l'évacuation de la partie de gaine isolante éliminée. Behind the fixed knife 11 is further provided a recess 21 allowing the evacuation of the insulated sheath part eliminated.

La machine conforme à l'invention fonctionne de la manière suivante
Le câble 3 est introduit à travers le dispositif 2 jusqu'à arriver en contact avec la butée règlable 17. La descente du marteau 19 au moyen du vérin 20 est alors commandée pour effectuer un serrage du câble 3, puis le vérin 13 actionne le couteau mobile 12 de manière à serrer le câble 3 contre le couteau 11 et à couper la gaine. Le vérin 6 est alors actionné et tire, au moyen des couteaux 11 et 12, sur la gaine, qui chute dans l'évidement 21.
The machine according to the invention operates as follows
The cable 3 is introduced through the device 2 until it comes into contact with the adjustable stop 17. The descent of the hammer 19 by means of the jack 20 is then controlled to effect a tightening of the cable 3, then the jack 13 actuates the knife mobile 12 so as to clamp the cable 3 against the knife 11 and cut the sheath. The jack 6 is then actuated and pulls, by means of knives 11 and 12, on the sheath, which falls into the recess 21.

Les vérins 6, 13 et 19 sont avantageusement des vérins pneumatiques et leur cycle de commande pneumatique, connu par ailleurs, n'est pas décrit. The cylinders 6, 13 and 19 are advantageously pneumatic cylinders and their pneumatic control cycle, known elsewhere, is not described.

Conformément à une autre caractéristique de l'invention, les couteaux 11 et 12 sont règlables sur leur support afin de permettre une adaptation à des diamètres de fils dif férents. According to another characteristic of the invention, the knives 11 and 12 are adjustable on their support in order to allow adaptation to different wire diameters.

Grâce à l'invention, il est possible de dénuder de manière très précise des câbles plats et de les introduire directement dans les circuits imprimés sans interposition de connecteurs. Thanks to the invention, it is possible to strip very precisely flat cables and to introduce them directly into printed circuits without interposition of connectors.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.  Of course, the invention is not limited to the embodiment described and shown in the accompanying drawing. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
