Definitions
- the subject of the invention is a device for crimping a contact on a electric cable. Some contacts are crimped in two places on a cable. A first crimping, called electrical crimping, is performed between a barrel of said contact and a conductive part of the cable. A second crimping, says sealing crimping is performed further upstream between the contact barrel and a sheath of the cable.

- the barrel is made of a deformable and conductive material.
- a bare part of the cable and a portion of the cable wrapped in a sheath are housed in the barrel.
- a first crimping, or electrical crimping allows connect the contact barrel to a core of the cable.
- the core of the cable designates strands stripped of the cable, that is to say not surrounded by the sheath.
- a second crimping, or crimping tight ensures a seal of the connection. For this the barrel of the contact is crimped on the sheath of the cable.
- the ovalization means are for example formed of two pads.
- a contact zone of each stud with the drum is flat. Both plots forming the ovalisation means are applied on both sides of the in order to flatten it. These flattened faces of the barrel are crimped on the sheath.
- the compression means are for example formed of two pads.
- Each stud has a contact zone with the barrel.
- the contact zone with the barrel has an outline that follows the ovoid contour of the ovoid faces of the barrel.
- the application compression means on the barrel crimps the ovoid faces of the on the sheath.
- Such ovalization and compression means make it possible to realize a tight crimp of a connection.
- the contact area of the means of compression should follow exactly the ovoid contour of the drum.
- the ovoid contour of the drum obtained after the application of the ovalization means varied. It is therefore necessary to use different compression means for each diameter of the cable to be crimped. Moreover, it is not possible to to control a quality of the tightness of the connection made by such crimping means.
- a crimping device is used, one of which crimping diameter can vary according to a user's needs, it's up to say according to a cable diameter.
- crimping diameter is meant the diameter that it is desired that the crimping device imposes on the shaft at the end of the crimping operation.
- the crimping device of the invention comprises a diaphragm.
- the diaphragm of the invention is provided of a plurality of jaws. A variation of a distance of the jaws compared at a center of the diaphragm allows to modify an opening diameter of said diaphragm.
- each jaw of the diaphragm is provided with means of guide.
- the guiding means are for example formed by rails along which the jaws slide, so as to approach or move away from center of the diaphragm.
- the guiding means are for example formed by rails along which the jaws slide, so as to approach or move away from center of the diaphragm.
- a crimping device of the invention provided with a number given jaws, it is possible to crimp sheaths of several diameters vary the aperture diameter of the diaphragm, away or close together the jaws of the center of the diaphragm. And by modifying a number of device of the invention, it is possible to obtain diaphragms covering each a different range of duct diameters, so as to allow a tight crimping for all diameters of existing ducts.
- the jaws have a triangular section.
- a section of the device of the invention is therefore polygonal and non-circular.
- a sheath of an electric cable and a barrel of a Crimp contact beforehand usually have a circular section. After crimping the barrel on the sheath using the device of the invention, the barrel has a polygonal section at the crimping point. It is therefore necessary to take into account, before crimping, tolerances after crimping each barrel.
- Each drum has a tolerance between a minimum diameter and a maximum diameter. If the diameter imposed on the barrel crimping is less than the minimum diameter, the drum is likely to to break up. and the cable will be weakened. If the diameter imposed by the sheath lodged in the barrel is greater than the maximum diameter, the barrel will not be enough restricted and tightness may not be ensured.
- the opening diameter of the diaphragm at the end of the crimping of the around the sheath must take into account these tolerances to ensure integrity and tightness of the connection.
- the barrel once crimped on the sheath of the cable has a polygonal section.

- round jaws is meant a jaw having a triangular section, but at least one side has a rounded end. A radius of curvature of one rounded end of each of the round jaws is directed to a center of the diaphragm.
- the section of the diaphragm In the closed position, that is to say for a minimum aperture diameter of the diaphragm, the section of the diaphragm is circular. This diameter corresponds to the minimum diameter that it can be crimped with such a crimping device. The crimp obtained with diameters close to this minimum opening diameter is perfectly waterproof.
- the section of the barrel, crimped on a sheath having a diameter close to minimum aperture diameter of the diaphragm is circular.
- the diaphragm section has a polygonal shape with rounded corners.
- the section of the barrel crimped on a sheath in such a case follows an internal contour the opening of the diaphragm.
- the section of the barrel crimped on the sheath has a polygonal shape with rounded corners.
- a change in the aperture diameter of the diaphragm can be controlled by a gears control device.
- the gears allow to slide the jaws on the rails their serving as guide means. It is also possible to use a conventional mechanical control device, for example comprising cams.
- the means of quality control of the crimping comprise for example sensors of measure of effort.
- Each jaw of the diaphragm can thus be provided with a force measurement sensor.
- Reference data may vary depending in particular on the material used forming the barrel of the crimp contact on the sheath. Indeed, depending on the material used to make the barrel, the effort required to move the jaws, and therefore crush the barrel on the sheath, will be different. Reference data have different values of effort to change the opening diameter the diaphragm from the maximum diameter of opening up to the diameter minimum. The reference data also include the values of the corresponding movements expected of the jaws, for each value effort. This gives a data memory a characteristic crimping reference effort / displacement. This characteristic of crimping serves as a baseline comparison to the processor for to check the quality of a crimping produced by means of the the invention.
- the processor verifies, depending on the force exerted on the diaphragm, whether the displacement of the jaws obtained corresponds to the expected displacement.
- the processor compares the values provided on the one hand by the force sensor and on the other hand by the displacement sensor, with the values corresponding to the crimping characteristic. If the values provided the sensors are identical to the expected values according to the reference characteristic, crimping is of good quality. sealing connection is assured. Conversely, if for a given effort the movement of the jaws is greater than the expected displacement, the connection may not be perfectly waterproof, or the connection may have been damaged. For example, a strand of the power cable may have been cut before or during crimping. The resistance of cable compression by the barrel is less than expected. So, the displacement obtained for a given effort is greater than that expected.
- crimping electrical means crimping the barrel of the contact on the core of the cable.
- a device for controlling the aperture diameter of the diaphragm can also operate the electric crimping device. So, we allows a simultaneous or almost simultaneous crimping of the barrel on the sheath of a apart and on the cable core on the other hand.
- This simultaneous double crimping In particular, it makes it possible to reduce the risks of moving the drum along the electrical cable between electrical crimping and waterproof crimping. Such displacement is for example the origin of the breakage of one or more strands cable. Also, by performing a simultaneous double crimping, we reduce the risk of breakage of the cable.
- the subject of the invention is therefore a device for crimping a drum of a contact on a sheath of an electric cable, characterized in that it comprises a diaphragm applying the barrel against the sheath.
- the diaphragm is formed of jaws, each jaw having a section of form globally triangular.

Description
L'invention a pour objet un dispositif de sertissage d'un contact sur un câble électrique. Certains contacts sont sertis en deux endroits sur un câble. Un premier sertissage, dit sertissage électrique, est réalisé entre un fût dudit contact et une partie conductrice du câble. Un deuxième sertissage, dit sertissage d'étanchéité, est réalisé plus en amont entre le fût du contact et une gaine du câble. L'invention a plus précisément pour objet un dispositif de sertissage d'un fût d'un contact sur une gaine d'un câble électriqueThe subject of the invention is a device for crimping a contact on a electric cable. Some contacts are crimped in two places on a cable. A first crimping, called electrical crimping, is performed between a barrel of said contact and a conductive part of the cable. A second crimping, says sealing crimping is performed further upstream between the contact barrel and a sheath of the cable. The subject of the invention is more specifically a device for crimping a barrel of a contact on a sheath of an electric cable
Un but de l'invention est de permettre un sertissage étanche d'un fût d'un contact sur une gaine d'un câble électrique. Un autre but de l'invention est de permettre le sertissage étanche de différents diamètres de câbles avec un même dispositif de sertissage. Un autre but de l'invention est d'assurer une bonne étanchéité du sertissage quel que soit le diamètre du câble électrique.An object of the invention is to allow a tight crimping of a barrel contact on a sheath of an electric cable. Another object of the invention is to allow the crimping of various cable diameters with the same crimping device. Another object of the invention is to ensure a good sealing of the crimp whatever the diameter of the electric cable.
En électronique, des câbles permettent de raccorder des systèmes électroniques entre eux ou de les relier à une alimentation électrique. D'une manière générale, il est indispensable de garantir la sécurité de ces connexions. Par ailleurs, dans le domaine de l'aéronautique une connexion entre un câble et un contact doit être fiable quelles que soient des conditions extérieures auxquelles elle est soumise. Par exemple, au niveau d'un avion, la température peut varier entre -50°C, lorsqu'il est dans les airs, et +40°C lorsqu'il est posé au sol. Ces variations de température sont subies en quelques heures. Or, des variations de température et de pression de grandes amplitudes ne doivent pas endommager les connexions électriques. Notamment, l'étanchéité d'une connexion est fondamentale pour empêcher les phénomènes de corrosion. L'intérêt de sertir les éléments intervenant dans une connexion électrique est donc capital dans le domaine de l'aéronautique.In electronics, cables make it possible to connect systems between them or to connect them to a power supply. On the one In general, it is essential to ensure the security of these connections. Moreover, in the field of aeronautics a connection between a cable and a contact must be reliable whatever the conditions external to which it is subject. For example, at the level of an airplane, the temperature can vary between -50 ° C, when in the air, and + 40 ° C when he is lying on the ground. These temperature variations are experienced in a few hours. However, variations in temperature and pressure large amplitudes should not damage electrical connections. In particular, the sealing of a connection is fundamental to prevent corrosion phenomena. The interest of crimping the intervening elements in an electrical connection is therefore crucial in the field of aeronautics.
On connaít, pour garantir une telle qualité de la connexion, des contacts à double sertissage. Un contact comporte un fût avec un pourtour extérieur tronconique. Un câble électrique est logé dans le fût. Le fût est fabriqué dans un matériau déformable et conducteur. Une partie dénudée du câble ainsi qu'une portion du câble enveloppé dans une gaine sont logées dans le fût. Un premier sertissage, ou sertissage électrique, permet de raccorder le fût du contact à une âme du câble. L'âme du câble désigne des brins dénudés du câble, c'est-à-dire non entourés par la gaine. Un deuxième sertissage, ou sertissage étanche, permet d'assurer une étanchéité de la connexion. Pour cela le fût du contact est serti sur la gaine du câble. Ces deux sertissages sont réalisés simultanément ou l'un après l'autre.In order to guarantee such a quality of connection, it is known that double crimp contacts. A contact has a barrel with a circumference frustoconical exterior. An electric cable is housed in the drum. The barrel is made of a deformable and conductive material. A bare part of the cable and a portion of the cable wrapped in a sheath are housed in the barrel. A first crimping, or electrical crimping, allows connect the contact barrel to a core of the cable. The core of the cable designates strands stripped of the cable, that is to say not surrounded by the sheath. A second crimping, or crimping tight, ensures a seal of the connection. For this the barrel of the contact is crimped on the sheath of the cable. These two crimps are made simultaneously or one after the other.
Pour réaliser le sertissage étanche, il est connu dans un premier temps d'appliquer, sur une zone du fût encadrant la gaine, des moyens d'ovalisation. Les moyens d'ovalisation sont par exemple formés de deux plots. Une zone de contact de chaque plot avec le fût est plane. Les deux plots formant les moyens d'ovalisation sont appliqués de part et d'autre du fût, afin de l'aplatir. Ces faces aplaties du fût sont serties sur la gaine. Dans un deuxième temps, une fois le fût partiellement aplati sur la gaine, on applique sur les deux faces ovoïdes du fût des moyens de compression. Les moyens de compression sont par exemple formés de deux plots. Chaque plot comporte une zone de contact avec le fût. La zone de contact avec le fût a un contour qui suit le contour ovoïde des faces ovoïdes du fût. L'application des moyens de compression sur le fût permet de sertir les faces ovoïdes du fût sur la gaine.To realize the tight crimping, it is known in a first time to apply, on an area of the shaft surrounding the sheath, means roundness. The ovalization means are for example formed of two pads. A contact zone of each stud with the drum is flat. Both plots forming the ovalisation means are applied on both sides of the in order to flatten it. These flattened faces of the barrel are crimped on the sheath. In a second time, once the cask partially flattened on the sheath, we applies on the two ovoid faces of the barrel compression means. The compression means are for example formed of two pads. Each stud has a contact zone with the barrel. The contact zone with the barrel has an outline that follows the ovoid contour of the ovoid faces of the barrel. The application compression means on the barrel crimps the ovoid faces of the on the sheath.
De tels moyens d'ovalisation et de compression permettent de réaliser un sertissage étanche d'une connexion. Cependant, pour garantir l'étanchéité de ce sertissage, la zone de contact des moyens de compression doit suivre exactement le contour ovoïde du fût. Or, selon un diamètre du câble électrique pour lequel on souhaite réaliser une connexion, le contour ovoïde du fût obtenu après l'application des moyens d'ovalisation varie. Il est donc nécessaire d'utiliser des moyens de compression différents pour chaque diamètre du câble à sertir. Par ailleurs, il n'est pas possible de contrôler une qualité de l'étanchéité de la connexion réalisée par de tels moyens de sertissage.Such ovalization and compression means make it possible to realize a tight crimp of a connection. However, to guarantee the tightness of this crimping, the contact area of the means of compression should follow exactly the ovoid contour of the drum. However, according to one diameter of the electric cable for which it is desired to make a connection, the ovoid contour of the drum obtained after the application of the ovalization means varied. It is therefore necessary to use different compression means for each diameter of the cable to be crimped. Moreover, it is not possible to to control a quality of the tightness of the connection made by such crimping means.
Dans l'invention, on cherche à résoudre les problèmes énoncés ci-dessus en proposant un dispositif de sertissage permettant de sertir de manière étanche des fûts de contacts sur des câbles de différents diamètres. On propose également un dispositif permettant de contrôler une étanchéité du sertissage réalisé.In the invention, it seeks to solve the problems stated above by proposing a crimping device for crimping sealed way of the contact barrels on cables of different diameters. It is also proposed a device for controlling a seal crimping done.
Pour arriver à ce résultat, on utilise un dispositif de sertissage dont un diamètre de sertissage peut varier selon des besoins d'un utilisateur, c'est à dire selon un diamètre du câble. Par diamètre de sertissage, on entend le diamètre qu'on souhaite que le dispositif de sertissage impose au fût en fin de l'opération de sertissage. Pour cela le dispositif de sertissage de l'invention comporte un diaphragme. Le diaphragme de l'invention est muni d'une pluralité de mors. Une variation d'un écartement des mors par rapport à un centre du diaphragme permet de modifier un diamètre d'ouverture dudit diaphragme. Pour cela, chaque mors du diaphragme est muni de moyens de guidage. Les moyens de guidage sont par exemple formés par des rails le long desquels coulissent les mors, de manière à s'approcher ou s'éloigner du centre du diaphragme. Par ailleurs, en modifiant le nombre de mors formant le diaphragme, on peut modifier une section dudit diaphragme. Ainsi, plus le nombre de mors est élevé, plus la section du diaphragme correspondant tend vers une section circulaire. Et plus la section du diaphragme est circulaire et plus les sertissages réalisés à l'aide d'un tel diaphragme sont étanches.To achieve this result, a crimping device is used, one of which crimping diameter can vary according to a user's needs, it's up to say according to a cable diameter. By crimping diameter is meant the diameter that it is desired that the crimping device imposes on the shaft at the end of the crimping operation. For this the crimping device of the invention comprises a diaphragm. The diaphragm of the invention is provided of a plurality of jaws. A variation of a distance of the jaws compared at a center of the diaphragm allows to modify an opening diameter of said diaphragm. For this, each jaw of the diaphragm is provided with means of guide. The guiding means are for example formed by rails along which the jaws slide, so as to approach or move away from center of the diaphragm. Moreover, by modifying the number of jaws forming the diaphragm, we can change a section of the diaphragm. So, the bigger the number of jaws is high, the corresponding section of the diaphragm tends to a circular section. And the more the diaphragm section is circular and more crimps made using such a diaphragm are waterproof.
Ainsi, pour un dispositif de sertissage de l'invention muni d'un nombre de mors donné, on peut sertir des gaines de plusieurs diamètres en faisant varier le diamètre d'ouverture du diaphragme, en éloignant ou rapprochant les mors du centre du diaphragme. Et en modifiant un nombre de mors du dispositif de l'invention, on peut obtenir des diaphragmes couvrant chacun une gamme différente de diamètres de gaines, de manière à permettre un sertissage étanche pour tous les diamètres de gaines existants.Thus, for a crimping device of the invention provided with a number given jaws, it is possible to crimp sheaths of several diameters vary the aperture diameter of the diaphragm, away or close together the jaws of the center of the diaphragm. And by modifying a number of device of the invention, it is possible to obtain diaphragms covering each a different range of duct diameters, so as to allow a tight crimping for all diameters of existing ducts.
Dans un exemple de réalisation de l'invention, les mors ont une section triangulaire. Une section du dispositif de l'invention est donc polygonale et non circulaire. Une gaine d'un câble électrique et un fût d'un contact avant sertissage ont généralement une section circulaire. Après sertissage du fût sur la gaine au moyen du dispositif de l'invention, le fût a une section polygonale à l'endroit du sertissage. Il est donc nécessaire de tenir compte, avant de procéder à un sertissage, des tolérances après sertissage de chaque fût. Chaque fût présente une tolérance comprise entre un diamètre minimum et un diamètre maximum. Si le diamètre imposé au fût par le sertissage est inférieur au diamètre minimum, le fût risque de se rompre. et le câble sera fragilisé. Si le diamètre imposé par la gaine logée dans le fût est supérieur au diamètre maximum, le fût ne sera pas assez restreint et l'étanchéité peut ne pas être assurée. In an exemplary embodiment of the invention, the jaws have a triangular section. A section of the device of the invention is therefore polygonal and non-circular. A sheath of an electric cable and a barrel of a Crimp contact beforehand usually have a circular section. After crimping the barrel on the sheath using the device of the invention, the barrel has a polygonal section at the crimping point. It is therefore necessary to take into account, before crimping, tolerances after crimping each barrel. Each drum has a tolerance between a minimum diameter and a maximum diameter. If the diameter imposed on the barrel crimping is less than the minimum diameter, the drum is likely to to break up. and the cable will be weakened. If the diameter imposed by the sheath lodged in the barrel is greater than the maximum diameter, the barrel will not be enough restricted and tightness may not be ensured.
Ainsi, le diamètre d'ouverture du diaphragme à la fin du sertissage du fût autour de la gaine doit tenir compte de ces tolérances pour assurer l'intégrité et l'étanchéité de la connexion.Thus, the opening diameter of the diaphragm at the end of the crimping of the around the sheath must take into account these tolerances to ensure integrity and tightness of the connection.
Dans l'invention, il est possible notamment de jouer sur le nombre de mors du diaphragme pour respecter les exigences de tolérances. On peut donc adapter une géométrie de l'ouverture du diaphragme à un rayon du fût le plus petit que l'on souhaite sertir avec ce dispositif de sertissage, en modifiant le nombre de mors formant le diaphragme, et donc un diamètre d'ouverture minimum dudit diaphragme.In the invention, it is possible in particular to play on the number of diaphragm jaws to meet tolerance requirements. We can therefore adapt a geometry of the opening of the diaphragm to a radius of the barrel the smallest one wishes to crimp with this crimping device, in modifying the number of jaws forming the diaphragm, and therefore a diameter of minimum opening of said diaphragm.
D'une manière générale, le fût une fois serti sur la gaine du câble a une section polygonale.In a general way, the barrel once crimped on the sheath of the cable has a polygonal section.
Dans un exemple de réalisation particulier de l'invention, le diaphragme comporte douze mors. La section du fût serti sur la gaine a alors une forme dodécagonale.In a particular embodiment of the invention, the diaphragm has twelve jaws. The section of the barrel crimped on the sheath then a dodecagonal form.
Dans un autre exemple de réalisation de l'invention, le diaphragme comportant huit mors. La section du fût serti sur la gaine a alors une forme octogonale.In another embodiment of the invention, the diaphragm having eight jaws. The section of the barrel crimped on the sheath then has a shape octagonal.
Dans un exemple de réalisation particulier de l'invention, on peut utiliser des mors ronds. Par mors ronds, on entend un mors ayant une section triangulaire, mais dont au moins un côté a une extrémité arrondie. Un rayon de courbure d'une extrémité arrondie de chacun des mors ronds est dirigé vers un centre du diaphragme. Ainsi, en position fermée, c'est-à-dire pour un diamètre d'ouverture minimum du diaphragme, la section du diaphragme est circulaire. Ce diamètre correspond au diamètre minimal que l'on peut sertir avec un tel dispositif de sertissage. Le sertissage obtenu avec des diamètres proches de ce diamètre d'ouverture minimum est parfaitement étanche. La section du fût, serti sur une gaine ayant un diamètre proche du diamètre minimum d'ouverture du diaphragme, est circulaire. Pour des diamètres de gaines à sertir s'éloignant de ce diamètre minimum d'ouverture, la section du diaphragme a une forme polygonale avec des angles arrondis. La section du fût serti sur une gaine dans un tel cas suit un contour interne de l'ouverture du diaphragme. Ainsi, la section du fût serti sur la gaine a une forme polygonale à angles arrondis.In a particular embodiment of the invention, it is possible to use round jaws. By round jaws is meant a jaw having a triangular section, but at least one side has a rounded end. A radius of curvature of one rounded end of each of the round jaws is directed to a center of the diaphragm. Thus, in the closed position, that is to say for a minimum aperture diameter of the diaphragm, the section of the diaphragm is circular. This diameter corresponds to the minimum diameter that it can be crimped with such a crimping device. The crimp obtained with diameters close to this minimum opening diameter is perfectly waterproof. The section of the barrel, crimped on a sheath having a diameter close to minimum aperture diameter of the diaphragm, is circular. For some diameters of crimp sleeves moving away from this minimum opening diameter, the diaphragm section has a polygonal shape with rounded corners. The section of the barrel crimped on a sheath in such a case follows an internal contour the opening of the diaphragm. Thus, the section of the barrel crimped on the sheath has a polygonal shape with rounded corners.
Une modification du diamètre d'ouverture du diaphragme peut être commandée par un dispositif de commande par engrenages. Par exemple, les engrenages permettent de faire coulisser les mors sur les rails leur servant de moyens de guidage. Il est également possible d'utiliser un dispositif de commande mécanique traditionnel, comportant par exemple des cames.A change in the aperture diameter of the diaphragm can be controlled by a gears control device. For example, the gears allow to slide the jaws on the rails their serving as guide means. It is also possible to use a conventional mechanical control device, for example comprising cams.
Dans un exemple de réalisation particulier de l'invention, on prévoit de munir le dispositif de sertissage de l'invention de moyens de contrôle d'une qualité du sertissage. C'est à dire des moyens permettant de vérifier que le sertissage réalisé correspond bien au sertissage attendu. Les moyens de contrôle de la qualité du sertissage comportent par exemple des capteurs de mesure d'effort. Chaque mors du diaphragme peut ainsi être muni d'un capteur de mesure d'effort.In a particular embodiment of the invention, provision is made for provide the crimping device of the invention with means for controlling a quality of crimping. That means means to verify that the crimping performed corresponds well to the expected crimping. The means of quality control of the crimping comprise for example sensors of measure of effort. Each jaw of the diaphragm can thus be provided with a force measurement sensor.
Avant une utilisation d'un dispositif de sertissage de l'invention, on entre en mémoire dans un processeur des données de références. Ces données de références peuvent varier en fonction notamment du matériau formant le fût du contact à sertir sur la gaine. En effet, selon le matériau utilisé pour réaliser le fût, l'effort nécessaire pour déplacer les mors, et donc écraser le fût sur la gaine, sera différent. Les données de références comportent différentes valeurs d'effort pour modifier le diamètre d'ouverture du diaphragme depuis le diamètre maximum d'ouverture jusqu'au diamètre minimum. Les données de références comportent également les valeurs des déplacements correspondants attendus des mors, pour chaque valeur d'effort. On obtient ainsi dans une mémoire de données une caractéristique de sertissage de référence effort/déplacement. Cette caractéristique de sertissage sert par la suite de base de comparaison au processeur pour contrôler la qualité d'un sertissage réalisé au moyen du dispositif de l'invention.Before using a crimping device of the invention, enters into memory in a processor of the reference data. These reference data may vary depending in particular on the material used forming the barrel of the crimp contact on the sheath. Indeed, depending on the material used to make the barrel, the effort required to move the jaws, and therefore crush the barrel on the sheath, will be different. Reference data have different values of effort to change the opening diameter the diaphragm from the maximum diameter of opening up to the diameter minimum. The reference data also include the values of the corresponding movements expected of the jaws, for each value effort. This gives a data memory a characteristic crimping reference effort / displacement. This characteristic of crimping serves as a baseline comparison to the processor for to check the quality of a crimping produced by means of the the invention.
Ainsi, à la fin d'un sertissage d'un fût d'un diamètre donné et dans un matériau donné sur une gaine d'un câble électrique d'un diamètre donné, le processeur vérifie, en fonction de l'effort exercé sur le diaphragme, si le déplacement des mors obtenu correspond au déplacement attendu. Le processeur compare les valeurs fournies d'une part par le capteur d'effort et d'autre part par le capteur de déplacement, avec les valeurs correspondantes sur la caractéristique de sertissage. Si les valeurs fournies par les capteurs sont identiques aux valeurs attendues d'après la caractéristique de référence, le sertissage est de bonne qualité. L'étanchéité de la connexion est assurée. A l'inverse, si pour un effort donné le déplacement des mors est supérieur au déplacement attendu, la connexion peut ne pas être parfaitement étanche, ou la connexion peut avoir été endommagée. Par exemple, un brin du câble électrique peut avoir été sectionné avant ou au moment du sertissage étanche. La résistance du câble à la compression par le fût est donc moindre que celle attendue. Ainsi, le déplacement obtenu pour un effort donné est plus important que celui attendu.Thus, at the end of a crimp of a barrel of a given diameter and in a given material on a sheath of an electric cable of a given diameter, the processor verifies, depending on the force exerted on the diaphragm, whether the displacement of the jaws obtained corresponds to the expected displacement. The processor compares the values provided on the one hand by the force sensor and on the other hand by the displacement sensor, with the values corresponding to the crimping characteristic. If the values provided the sensors are identical to the expected values according to the reference characteristic, crimping is of good quality. sealing connection is assured. Conversely, if for a given effort the movement of the jaws is greater than the expected displacement, the connection may not be perfectly waterproof, or the connection may have been damaged. For example, a strand of the power cable may have been cut before or during crimping. The resistance of cable compression by the barrel is less than expected. So, the displacement obtained for a given effort is greater than that expected.
Il est possible de coupler une action du dispositif de sertissage étanche à une action d'un dispositif de sertissage électrique. Par sertissage électrique, on entend le sertissage du fût du contact sur l'âme du câble. Par exemple, un dispositif de commande du diamètre d'ouverture du diaphragme peut également actionner le dispositif de sertissage électrique. Ainsi, on permet un sertissage simultané ou quasi simultané du fût sur la gaine d'une part et sur l'âme du câble d'autre part. Ce double sertissage simultané permet notamment de diminuer les risques de déplacement du fût le long du câble électrique entre le sertissage électrique et le sertissage étanche. Un tel déplacement est par exemple à l'origine de la rupture d'un ou plusieurs brins du câble. Aussi, en réalisant un double sertissage simultané, on diminue les risques de casse du câble.It is possible to couple an action of the crimping device impervious to an action of an electric crimping device. By crimping electrical means crimping the barrel of the contact on the core of the cable. By for example, a device for controlling the aperture diameter of the diaphragm can also operate the electric crimping device. So, we allows a simultaneous or almost simultaneous crimping of the barrel on the sheath of a apart and on the cable core on the other hand. This simultaneous double crimping In particular, it makes it possible to reduce the risks of moving the drum along the electrical cable between electrical crimping and waterproof crimping. Such displacement is for example the origin of the breakage of one or more strands cable. Also, by performing a simultaneous double crimping, we reduce the risk of breakage of the cable.
L'invention a donc pour objet un dispositif de sertissage d'un fût d'un contact sur une gaine d'un câble électrique, caractérisé en ce qu'il comporte un diaphragme appliquant le fût contre la gaine.The subject of the invention is therefore a device for crimping a drum of a contact on a sheath of an electric cable, characterized in that it comprises a diaphragm applying the barrel against the sheath.
Selon un exemple particulier de réalisation de l'invention, le diaphragme est formé de mors, chaque mors ayant une section de forme globalement triangulaire. Par section de forme globalement triangulaire on entend une section a trois côtés formés par trois droites, mais également une section à trois côtés dont au moins un des côtés a une extrémité arrondie.According to a particular embodiment of the invention, the diaphragm is formed of jaws, each jaw having a section of form globally triangular. By section of generally triangular shape hears a three-sided section formed by three straight lines, but also a three-sided section of which at least one of the sides has a rounded end.
L'invention concerne également un fût d'un contact serti sur une gaine d'un câble, caractérisé en ce que le fût a une section de forme polygonale.The invention also relates to a barrel of a contact crimped on a sheath a cable, characterized in that the shaft has a polygonal section.
L'invention concerne également un fût d'un contact serti sur une gaine d'un câble, caractérisé en ce que le fût a une section de forme circulaire.The invention also relates to a barrel of a contact crimped on a sheath a cable, characterized in that the shaft has a circular section.

Sur la figure 1, est représenté un dispositif de sertissage 100 de
l'invention. Le dispositif 100 encadre partiellement un fût 301 d'un contact
300. Dans le fût 300 est logé un câble 200 électrique. Une âme 202 du câble
200 est logée à l'endroit d'une extrémité fermée 302 du fût 300. Des parois
internes 303 de l'extrémité fermée 302 du fût 301 sertissent l'âme 202 du
câble 200. Une portion du câble 200, munie de la gaine 201, est logée dans
le fût 301 à l'endroit d'une extrémité ouverte 304 du fût 300.FIG. 1 shows a crimping
Le dispositif de sertissage 100 de l'invention doit permettre de sertir
des parois internes 305 de l'extrémité ouverte 304 du fût 301 contre la gaine
201, afin d'assurer une étanchéité de la connexion entre le câble 200 et le
contact 300.The crimping
Le dispositif de sertissage 100 selon l'invention peut s'adapter à
différents diamètres de câbles 200 et de fûts 300. C'est-à-dire qu'un même
dispositif de sertissage 100 peut permettre un sertissage étanche de
différents diamètres de fûts 300 et de câbles 200. Pour cela, le dispositif 100
de sertissage de l'invention comporte un diaphragme 101 (figure 2).The crimping
Sur la figure 2 est représenté un exemple de réalisation du dispositif
100 de sertissage de l'invention. Le diaphragme 101 est formé de huit mors
102. Un déplacement des mors 102 en direction d'un centre C du
diaphragme 101 permet de diminuer un diamètre d d'ouverture dudit
diaphragme 101. Inversement, en éloignant les mors 102 du centre C du
diaphragme 101, on augmente le diamètre d'ouverture d du diaphragme 101.
Selon le diamètre d'ouverture d du diaphragme 101, on peut sertir des fûts
de différents diamètres sur des câbles de différents diamètres.FIG. 2 shows an exemplary embodiment of the
Dans l'exemple présenté à la figure 2, un dispositif de commande 103
du diamètre d'ouverture d du diaphragme 101 permet de modifier selon des
besoins d'un utilisateur le diamètre d'ouverture d du diaphragme 101. Pour
cela, le dispositif de commande 103 actionne un dispositif 104 à cames. Le
dispositif 104 à cames est formé d'un cylindre 110 creux dans lequel sont
logés les mors 102 du diaphragme 101. Un contour interne du cylindre 110
est muni de quatre cames hautes 105 disposées régulièrement sur un
pourtour circulaire du cylindre 110. Une face externe 106 de quatre premiers
mors 102 est munie d'un bossage 107 venant en contact avec une came
haute 105. Le contour interne du cylindre 110 est également muni de quatre
cames basses (non visibles sur la figure 2) disposées régulièrement sur le
pourtour circulaire du cylindre 110. Les cames basses sont disposées en
quinconces avec les cames hautes 105. Une face externe 106 de chacun
des quatre autres mors 102 est munie d'un bossage 111 venant en contact
avec une came basse. Les mors 102 munis d'un bossage 107 à l'endroit
d'une extrémité haute sont alternés avec les mors 102 munis d'un bossage
111 à l'endroit d'une extrémité basse. Ainsi, une came 105 du dispositif 104 à
cames permet de déplacer simultanément deux mors 102 accolés.In the example shown in FIG. 2, a
Un actionnement du dispositif de commande 103 permet une rotation
du cylindre 104 autour du diaphragme 101, imposant aux mors 102 du
diaphragme 101 un déplacement vers le centre C, ou au contraire dans une
direction opposée au centre C.An actuation of the
Le dispositif de commande 103 est par exemple un dispositif
électronique permettant de commander à distance la rotation du cylindre 104
vers la gauche G ou vers la droite D, afin d'augmenter ou de diminuer le
diamètre d'ouverture d du diaphragme 101. Il est possible de prévoir que le
dispositif de commande 103 puisse également actionner un dispositif de
sertissage électrique (non représenté) de l'extrémité fermée 302 du fût 300
sur la partie dénudée 202 du câble 200. Une touche SE spécifique peut être
prévue à cet effet sur le dispositif 103 de commande.The
Dans un exemple de réalisation particulier de l'invention, et tel que
cela est représenté à la figure 3, les mors 102 du diaphragme 101 ont une
section triangulaire à faces planes. C'est à dire que chaque côté de la
section triangulaire est droit. Une ouverture 108 du diaphragme 101 a donc
une section polygonale. Or, la gaine 201 du câble 200 à sertir et le fût 301
ont une section circulaire. Un diamètre final du fût 301 à l'endroit du
sertissage autour de la gaine 201 varie donc d'un point P1 à un autre point
P2 du sertissage. Cependant, un diamètre maximum dmax et un diamètre
minimum dmin du fût 301 à l'endroit du sertissage doivent rester dans une
gamme de tolérances du fût. Selon les tolérances du fût à sertir, on peut
prévoir un diaphragme 101 avec un nombre de mors 102 plus ou moins
grand.In a particular embodiment of the invention, and such that
this is shown in Figure 3, the
Sur les figures 4a et 4b est représenté un autre exemple de réalisation
du diaphragme 101 de l'invention. Une extrémité d'un côté 109 de la section
de forme triangulaire de chaque mors 102 est arrondie. Un rayon de
courbure de l'extrémité arrondie est dirigé vers le centre C du diaphragme
101. Ainsi, comme cela est représenté sur la figure 4b pour un diamètre
d'ouverture faible du diaphragme 101, la section de l'ouverture 108 est
circulaire. Le sertissage obtenu pour cette section circulaire est parfaitement
étanche, puisqu'il oblige le fût 301 à suivre un contour de la gaine 201.FIGS. 4a and 4b show another embodiment
of the
Pour des diamètres d'ouverture plus grands du diaphragme 101, on
obtient un polygone dont les quatre angles sont arrondis comme cela est
représenté sur la figure 4a. Une longueur L des parties droites des côtés
arrondis 109 des mors 102 augmente avec le diamètre d'ouverture du
diaphragme 101.For larger aperture diameters of the
Dans un exemple de réalisation particulier de l'invention, on peut
munir le dispositif de sertissage 100 de moyens de contrôle du sertissage du
fût 301 sur la gaine 201 (non représentés sur les figures). Par exemple, on
peut munir chaque mors 102 d'un capteur d'un effort exercé sur ledit mors
102. On peut munir également chaque mors 102 d'un capteur du
déplacement du mors 102 par rapport au centre C du diaphragme 101. Ainsi,
on peut contrôler le déplacement du mors 102 en fonction de l'effort exercé
sur ledit mors 102. Si le déplacement du mors 102 ne correspond pas au
déplacement attendu pour l'effort exercé sur le mors 102, le sertissage du fût
301 sur la gaine 201 peut être défaillant.In a particular embodiment of the invention, it is possible to
provide the crimping
Le dispositif de sertissage de l'invention permet donc de garantir un sertissage étanche du fût d'un contact sur la gaine d'un câble électrique, notamment en complément d'un sertissage électrique du fût sur les brins du câble. La connexion entre le contact et le câble électrique selon l'invention est parfaitement étanche. Un même dispositif de sertissage selon l'invention permet de sertir un grand nombre de fûts de diamètres différents sur des gaines de câbles électriques de diamètre différents.The crimping device of the invention thus makes it possible to guarantee a tight crimp of the barrel of a contact on the sheath of an electric cable, in particular in addition to an electric crimping of the barrel on the strands of the cable. The connection between the contact and the electric cable according to the invention is perfectly waterproof. The same crimping device according to the invention allows to crimp a large number of drums of different diameters on sheaths of electric cables of different diameters.
