Description
~~43~~0 La présente invention concerne un procédé pour relier un conducteur électrique à une broche d'un connecteur, ainsi que la liaison électrique obtenue par mise en oeuvre dudit procêdé.
La plupart de ces connexions sont actuellement réalisées par Ie sertissage d°un manchon, reliê à la broche, sur Ie conducteur électrïque prëalablement dënudê.
Le dënLidage des conducteurs électriques est classique ment effectuë à l'aide d'une pince manuelle êquipée de l0_ couteaux comportant diffërents passages adaptés, chacun;
à un diamëtre de conducteur déterminë. L'opérateur v choisit le diamètre correct des couteaux, présente Ie conducteur dans la pince, et la manoeuvre pour faire pénétrer les couteaux dans l'isolant jusqu'au niveau de l'âme du conducteur. Un mouvement longitudinal des couteaux fera glisser l'isolant sur l'âme en 1°êjectant.
Le conducteur êlectrique est ainsi dénudé et prêt à ëtre équipé de sa broche.
Cette apëration étant efFectuée manuellement, des endommagements de l'âme du conducteur et un mauvais contact avec Ia broche ou une mauvaise tenue du sertis Sage peuvent ëtre provoquês par - une longueur de dénudage incorrecte (celle-ci étant estimée à vue par l'opërateur~
- un êtat défectueux de l'outil de dénudage ;
- une erreur de l'opérateur sur le diamëtre des coü-teaux e . un diamètre inférieur entraînant une destruction des brins ; et . un diamëtre supérieur provoquant un dénudage impar-fart avec sertissage sur 1°isolant ;
- 1a tolérance sur le diamètre de l'âme du conducteur ;
~~43~80 ~~ 43 ~~ 0 The present invention relates to a method for connecting a electrical conductor to a connector pin, as well as the electrical connection obtained by setting work of the said process.
Most of these connections are currently made by crimping a sleeve, connected to the pin, on Ie electrical conductor previously stripped.
The unwinding of electrical conductors is classic carried out using manual pliers fitted with l0_ knives with different adapted passages, each;
to a determined conductor diameter. The operator v choose the correct diameter of the knives, present Ie conductor in the clamp, and the maneuver to make penetrate the knives into the insulation up to the level of the driver's soul. Longitudinal movement of knives will slide the insulation over the core by ejecting it first.
The electrical conductor is thus stripped and ready to be equipped with its spindle.
This aperitif being carried out manually, driver soul damage and bad contact with the spindle or poor resistance of the seam Wise can be caused by - an incorrect stripping length (this being estimated by sight by the operator ~
- a defective condition of the stripping tool;
- an operator error on the diameter of the costs heads and . a smaller diameter causing destruction of strands; and . a larger diameter causing imperfect stripping wax with crimp on 1 ° insulator;
- 1a tolerance on the diameter of the conductor core;

2 - le repliage d'un brin du conducteur lors de son introduction dans le manchon de la b:COChe.
Par ailleurs, l'utilisation éventuelle de moyens méca-niques, tels que couteaux tournants, laser, pose d'au-tres problèmes liés à leur complexité et à 1a difficulté
de leur mise en oeuvre.
. La présente invention a pour but d'éviter ces incanvé-nients, et concerne un procédé pour relier un conducteur électrique à une broche d'un connecteur permettant d'éviter tout endommagement du conducteur et/ou un mauvaïs contact avec la broche.
A cet effet, le procédë pour relier un conducteur électrique à une broche d'un connecteur, ladite broche comportant un manchon dans lequel une extrémité dudit conducteur est destinée à étre introduite; procédê
comportant le sertissage dudit manchon sur ledit conduc-teur, est remarquable, selon l'invention, en ce que, avant de sertir le manchon de la broche-sur le canduc-teur, un adhésif électriquement conducteur est amené
dans ledit manchon et ladite extrémité du conducteur est insérée, sans dénuder celle-ci, dans ledit manchon; de sorte que ledit adhésif relie,, de façon électriquement conductrice, le conducteur:à la broche.
Ainsi, la connexion électrique entre le conducteur et la broche peut être obtenue, de façon fiable, sans qu'il sait nécessaire de dénuder l'extrêmité du conducteur, avec les inconvénients que cala implique, et/ou sans avoir recours à des outils spéciaux, la face d'extrëmité
de l'âme métallique du conducteur étant reliée, de façon.
électriquement conductrice, à la broche paz l'intermê-diaire dudit adhésif.

En particulier, une dose prédéterminëe d'adhésif peut être amenée dans le farad du manchon.
Avantageusement, l'extrémité du conducteur est coupée en biseau avant san insertion dans ledit manchon, notamment sous un angle au moins sensiblement égal à 45°.
Par ailleurs, en tant qu'adhésif, on peut utiliser une colle chargée d'un métal, ladite colle pouvant êtxe, en particulier, une pâte thixotroge êpoxy à charge d'ar-gent.
l0 Les figures du dessin annexé feront bien comprendre comment l'invention peut être réalisée.v La figure 1 montre une broche de connecteur munie d'un w manchon destiné à recevoir l'extrémité d'un conducteur électrique.
La figure 2 illustre la liaison; selon l'invention;
entre la broche et le conducteur de la figure 1.
La broche 1 de connecteur, montrée sur la figure 1;
comporte un manchon cylindrique 2 danê lequel est destinée à être insérée l'extrémité 3 dyun conducteur électrique, comportant une âme métallique 4 entourée d'une gaine isolante 5.
Selon l'invention, un adhésif durcissable électriquement conducteur 6 est tout d'abord amené au tond du manchon 2, à une dose prédéterminée par les caractéristiques dimensionnelles du manchon et danc du conducteur. Gela peut être fuit par tout moyen approprïé, comme par exemple une seringue micrométrique graduée. Cet adhésif peut être notamment une pâte thixotrope êpoxy à charge d'argent, comme celle fournie par la Sociëtë EPO~ECNY
sous le nom commercial EPO-TEK 917, dont les carartëris--tiques techniques sont les suivantes .
- résistivitë électrique : 0,05 à 0,07 milliohm/cm.
- cycles de polymérisation 1/2 heure à 150° C
1 heure à 100° C
2 heures à 80° C
2 à 3 jours à tempërature ambiante.
- tempêrature de dêgradation aprës polymêrisation 350°C.
Avantageusement, l'extrêmité 3 du conducteur est bi-seautée, notamment sous un angle au moins sensiblemewt égal à ~5°, de façon à augmenter la surface de contact entre celle-ci et l'adhésif, au niveau de la face Z5 d'extrémité de l'âme métallique 4.
Puis, l'extrémité 3 du conducteur est insérée, sans' dénuder celle-ci, dans le 'manchon 2, jusqu'à venir au contact de l'adhésif 6 qui baignera celle-ci, notamment la face d'extrémité de l'âme mëtallique 4; et reliera ainsi, de façon électriquement conductrice, le conduc teur à la broche, après quoi le manchon 2 est serti sur ladite extrémité 3, de façon classique, en 7 (figure ~);
cette liaison étant renforcée par le durcissement de . 1°adhésif.
Les calculs montrent qize la chute de tension au niveau d'une telle liaison, même dans les conditions les plus défavorables, est négligeable et, en tout cas, bien inférieure â celle, par exemple, entxe des broches mâle et femel7.e d'un connecteur.
Par ailleurs, si le procédê de l'invention permet de supprimer le dénudage des canducteurs êlectr:iques, il convient de noter que, par là même, il est nécessaire d'adapter la taille des laroches à monter sur des conduc~

nients, and relates to a method for connecting a conductor electrical to a pin of a connector allowing avoid damage to the conductor and / or bad contact with the spindle.
To this end, the process for connecting a conductor electrical to one pin of a connector, said pin having a sleeve in which one end of said conductor is intended to be introduced; process comprising crimping said sleeve on said conduc-is remarkable, according to the invention, in that, before crimping the spindle sleeve-on the canduc-an electrically conductive adhesive is supplied in said sleeve and said end of the conductor is inserted, without stripping the latter, into said sleeve; of so that said adhesive connects, electrically conductive, the conductor: at the spindle.
Thus, the electrical connection between the conductor and the pin can be obtained, reliably, without it knows that it is necessary to strip the end of the conductor, with the disadvantages that cala implies, and / or without use special tools, the end face of the metallic core of the conductor being connected, so.
electrically conductive, to the pin paz the intermed-diary of said adhesive.

In particular, a predetermined dose of adhesive may be brought into the farad of the sleeve.
Advantageously, the end of the conductor is cut in bevel before insertion into said sleeve, in particular at an angle at least substantially equal to 45 °.
Furthermore, as an adhesive, a glue loaded with a metal, said glue being able to be in particular, an epoxy thixotroge paste with an ar-nice.
l0 The figures in the accompanying drawing will make it clear how the invention can be realized.v Figure 1 shows a connector pin with a w sleeve intended to receive the end of a conductor electric.
Figure 2 illustrates the link; according to the invention;
between the pin and the conductor of figure 1.
The connector pin 1, shown in Figure 1;
includes a cylindrical sleeve 2 which is intended to be inserted end 3 of a conductor electric, having a metallic core 4 surrounded an insulating sheath 5.
According to the invention, an electrically curable adhesive conductor 6 is first brought to the mowing of the sleeve 2, at a dose predetermined by the characteristics dimensions of the sleeve and danc of the conductor. Gela may be fled by any suitable means, such as example a graduated micrometric syringe. This adhesive may in particular be a charge epoxy thixotropic paste of money, like that provided by the Company EPO ~ ECNY
under the trade name EPO-TEK 917, including the carartëris--Technical ticks are as follows.
- electrical resistivity: 0.05 to 0.07 milliohm / cm.
- polymerization cycles 1/2 hour at 150 ° C
1 hour at 100 ° C
2 hours at 80 ° C
2 to 3 days at room temperature.
- degradation temperature after polymerization 350 ° C.
Advantageously, the end 3 of the conductor is bi-jagged, especially from an angle at least sensiblemewt equal to ~ 5 °, so as to increase the contact surface between it and the adhesive, at the face Z5 at the end of the metal core 4.
Then, the end 3 of the conductor is inserted, without ' strip it, in the 'sleeve 2, until it comes to contact of the adhesive 6 which will bathe it, in particular the end face of the metal core 4; and will connect thus, electrically conductive, the conduc spindle, after which sleeve 2 is crimped onto said end 3, conventionally, at 7 (Figure ~);
this bond being reinforced by the hardening of . 1 ° adhesive.
The calculations show qize the voltage drop at the level of such a link, even under the most difficult conditions unfavorable, is negligible and, in any case, good less than, for example, male pin spacing and femel7.e of a connector.
Furthermore, if the process of the invention allows remove the stripping of electric canductors, it it should be noted that, by the same token, it is necessary to adapt the size of the laroches to be mounted on conduits ~
