- the resistance of the electrical connector 1 is therefore reduced.
- the electrical resistance of the electrical connector 1, measured over a length L between the bases of the rings, is almost equal to that of the conductive portion of portions of electrical cable over this same length.
- the compression members 40A to 40D expand less and exert a stronger centripetal radial pressure on the strips 38 than in the unheated state. This results in an increase in the pressure exerted by lamellae 38 on the insertable part 12, and an increase in the contact surface between the lamellae and the insertable part. This reduces the contact resistance and causes a reduction in the heating of the electrical connector 1 during use.
- the electrical connector 1 In the inserted position, the electrical connector 1 has great mechanical stability thanks to the structure of the strips 38 and to the action of the compression members 40A to 40D. In addition, the insertion of the male contact 5 into the female contact 10 remains very easy due to the flexibility of the strips 38 and the elasticity of the compression members 40A to 40D.
- the electrical connector 1 is therefore extremely efficient, both with regard to ease of insertion and resistance to vibrations.
- the electrical connector 1 has a small footprint compared to its electrical performance.
- the electrical connector 1 Due to its relatively simple structure, without interface, the electrical connector 1 remains simple to manufacture and at a competitive price.
- the female contact 110 constituting a variant of the female contact 10.
- the female contact 110 is analogous to the female contact 10 represented on the Figures 1 to 3 . Similar elements have the same reference numbers and will not be described again. Only the differences will be described below.
- the body 34 of the female contact 110 defines a groove 112 extending around the insertion axis D and opening into the housing 14. Axially the groove 112 extends between the bottom 44 of the housing 14 and the strips 38.
- the groove 112 is delimited axially, on the side of the ring 36 (not shown in the figure 6 ) through the bottom 44 of the housing 14.
- the groove 112 is adapted to weaken, by thinning, the body 34 at the base of the strips 38. This makes it possible to reduce the force of insertion of the male contact 5 by reducing the bending moment by 10% without degrading the functioning. connector 1.
- the female contact 10 comprises eight strips 38, and there are four retention members 40A to 40D, as shown in the figure 3 .
- the eight strips are numbered successively from 38.1, 38.2 to 38.8.
- the strips 38.1 and 38.8 are located angularly on either side of one of the slots 52.
- the dimensions of the slats are, for example: length: 33 mm; width 5.70 mm, height: 3.5 mm.
- the homogeneous distribution makes it possible to have a homogeneous behavior during the operation of the slats (same contact pressure for each slat with the male contact). This improves electrical performance, the life of the connector and resistance to vibrations (elimination of the risk of loss of contact).
- the angular offsets at 360 ° / N have made it possible to increase the contact surface and have made its distribution over the strips more homogeneous.

On connaît actuellement deux catégories de ces connecteurs électriques. Une première catégorie englobe les connecteurs ayant une interface destinée à garantir une bonne surface de contact. L'interface est habituellement réalisée à l'aide de fils ou d'une plaque emboutie afin de créer la forme adéquate. Cette catégorie a l'avantage de présenter de faibles efforts d'insertion et une bonne tenue aux vibrations. Toutefois, le nombre de pièces utilisées pour réaliser l'interface est relativement élevé, et l'espace occupé par l'interface crée un encombrement. En outre, ce type de connecteur est d'un prix relativement élevé.Two categories of these electrical connectors are currently known. A first category includes connectors having an interface intended to guarantee a good contact surface. The interface is usually performed using wires or a stamped plate to create the proper shape. This category has the advantage of having low insertion forces and good resistance to vibrations. However, the number of parts used to make the interface is relatively high, and the space occupied by the interface creates space. In addition, this type of connector is relatively expensive.
Dans la seconde catégorie, le contact électrique est assuré par la pression des deux contacts, qui doit être élevée, afin de compenser une faible surface de contact. Ces connecteurs présentent un coût de fabrication plus faible, mais également des efforts d'insertion élevés et une tenue moins bonne aux vibrations et au fretting, c'est-à-dire à l'usure de contact qui affecte les surfaces en contact du contact mâle et du contact femelle.In the second category, the electrical contact is ensured by the pressure of the two contacts, which must be high, in order to compensate for a small contact surface. These connectors have a lower manufacturing cost, but also high insertion forces and less good resistance to vibrations and fretting, that is to say contact wear which affects the contact surfaces of the contact. male and female contact.
Afin d'améliorer la qualité de ce type de connecteur électrique, il a été proposé que le contact femelle comporte des lamelles souples entourant la partie insérable du contact mâle, un organe de contention annulaire, formé par une lame recourbée en forme de « C », est parfois utilisé pour augmenter la pression des lamelles sur la partie insérable.In order to improve the quality of this type of electrical connector, it has been proposed that the female contact comprises flexible lamellae surrounding the insertable part of the male contact, an annular compression member, formed by a curved blade in the shape of a "C". , is sometimes used to increase the pressure of the slats on the insertable part.
Toutefois, il a été constaté que ces connecteurs, bien que donnant satisfaction car offrant un effort d'insertion raisonnable, présentent néanmoins une résistance électrique relativement élevée. En effet, notamment lorsque le connecteur sert à relier électriquement des portions de câble en aluminium ou en alliage d'aluminium, la résistance du connecteur reste sensiblement supérieure à celle d'une portion de câble de longueur équivalente.However, it has been found that these connectors, although satisfactory since offering a reasonable insertion force, nevertheless have a relatively high electrical resistance. Indeed, especially when the connector is used to electrically connect portions of aluminum or aluminum alloy cable, the resistance of the connector remains substantially greater than that of a portion of cable of equivalent length.
Un but de l'invention est donc de fournir un connecteur électrique présentant toujours un effort d'insertion raisonnable, mais aussi une résistance électrique inférieure, tout en restant d'une fabrication simple et d'un prix compétitif.An object of the invention is therefore to provide an electrical connector always having a reasonable insertion force, but also a lower electrical resistance, while remaining simple to manufacture and at a competitive price.
A cet effet, l'invention a pour objet un connecteur électrique selon la revendication 1.To this end, the invention relates to an electrical connector according to
Selon des modes particuliers de réalisation, le connecteur électrique comprend l'une ou plusieurs des caractéristiques correspondant aux revendications 2 à 11, prise(s) isolément ou selon toutes les combinaisons techniquement possibles.According to particular embodiments, the electrical connector comprises one or more of the characteristics corresponding to claims 2 to 11, taken alone or in any technically possible combination.

En référence aux
Le connecteur électrique 1 comprend un contact mâle 5 et un contact femelle 10 mobiles entre une position insérée (
La position non insérée se déduit facilement de la position insérée représentée sur les
Le connecteur électrique 1 comprend avantageusement un premier isolant électrique 16 adapté pour être inséré dans le logement 14 pour protéger un utilisateur (non représenté) du connecteur électrique. De même, avantageusement, le connecteur électrique 1 comprend un deuxième isolant électrique 18 adapté pour recouvrir une extrémité distale 20 de la partie insérable 12 du contact mâle 5.The
Par « distal », on entend, pour chacun des contacts, le côté défini par le sens d'insertion suivant l'axe d'insertion D. Corrélativement, on entend par « proximal » le côté opposé à l'insertion suivant l'axe d'insertion D.By "distal" is meant, for each of the contacts, the side defined by the direction of insertion along the insertion axis D. Correspondingly, by "proximal" is meant the side opposite to the insertion along the axis Insertion D.
Le connecteur électrique 1 comprend en outre avantageusement des gaines isolantes (non représentées) entourant respectivement le contact mâle 5 et le contact femelle 10 autour de l'axe d'insertion D pour protéger ces contacts de tout contact électrique latéral, notamment avec un opérateur (non représenté). Les gaines isolantes sont évidemment adaptées pour ne pas s'opposer à l'insertion du contact mâle 5 dans le contact femelle 10 et pour assurer une protection à la fois dans la position non insérée et la position insérée.The
Le contact mâle 5 et le contact femelle 10 sont adaptés pour être en contact électrique avec au moins deux portions de câble électrique 22, 24, chacune comportant respectivement une partie conductrice 26, 28, et une gaine isolante 30, 32 entourant la partie conductrice, sauf, dans l'exemple, sur une portion distale de la partie conductrice.The
Au sens de la présente demande, on entend par « conducteur » un matériau dont la résistivité électrique à 300 K est par exemple inférieure ou égale à 10-5 Ω.m. A contrario, on entend par « isolant » un matériau dont la résistivité électrique à 300 K est par exemple supérieure ou égale à 105 Ω.m.For the purposes of the present application, the term "conductor" means a material whose electrical resistivity at 300 K is for example less than or equal to 10 -5 Ω.m. Conversely, the term “insulator” means a material whose electrical resistivity at 300 K is for example greater than or equal to 10 5 Ω.m.
La partie conductrice 30, 32 est par exemple en aluminium ou en alliage d'aluminium.The
Par « alliage d'aluminium », on entend ici par exemple un alliage dont le composant principal est l'aluminium, à un pourcentage en masse prédominant dans la composition de l'alliage.By “aluminum alloy” is meant here for example an alloy of which the main component is aluminum, at a predominant percentage by mass in the composition of the alloy.
Les alliages d'aluminium considérés sont par exemples AL6060The aluminum alloys considered are for example AL6060
Le contact femelle 10 comprend un corps 34, une bague 36 fixée sur le corps et recevant la portion de câble électrique 24, une pluralité de lamelles 38 faisant saillie axialement à partir du corps, et une pluralité 40 d'organes de contention 40A, 40B, 40C, 40D annulaires structurellement analogues les uns aux autres et disposés sur des faces 42 radialement extérieures des lamelles 38.The
Le corps 34, la bague 36 et les lamelles 38 sont conducteurs. Ils sont par exemple respectivement en aluminium ou en alliage d'aluminium.The
Le corps 34 définit un fond 44 du logement 14, par exemple de forme cylindrique et dans lequel le premier isolant 16 est inséré. Le corps 34 comporte une face 46 plane sur laquelle la partie conductrice 28 et la bague 36 sont soudées par friction. Dit autrement, il existe une soudure plane entre le corps 34, d'une part, et la bague 36 et la partie conductrice 28, d'autre part, obtenue par friction, en faisant tourner à haute vitesse le corps sur la bague et la partie conductrice.The
Dans l'exemple, la face 46 est perpendiculaire à l'axe d'insertion D. Ainsi, la soudure par friction est réalisée en faisant tourner le corps par rapport à la bague 36 et à la partie conductrice 28 autour de l'axe d'insertion D.In the example, the
Le fond 44 définit avantageusement une cavité 48 pour fixer le premier isolant 16 sur le corps 34.The
Les lamelles 38 sont réparties angulairement autour de la partie insérable 12 dans la position insérée. Les lamelles 38 sont au moins au nombre de deux. Dans l'exemple représenté, les lamelles 38 sont au nombre de huit.The
Selon des variantes non représentées, il y a quatre, six, huit, dix ou douze lamelles 38.According to variants not shown, there are four, six, eight, ten or twelve
Les lamelles 38 délimitent radialement le logement 14.The
Les lamelles 38 sont avantageusement identiques les unes aux autres et réparties régulièrement autour de l'axe d'insertion D. Deux lamelles 38 angulairement consécutives sont avantageusement séparées par une fente 50.The
Chacune des lamelles 38 définit respectivement une rainure circonférentielle 52, et ces rainures circonférentielles sont alignées les unes avec les autres autour de l'axe d'insertion D et adaptées pour recevoir tous les organes de contention 40A à 40D.Each of the
Selon une variante non représentée, chaque lamelle 38 définit plusieurs rainures circonférentielles parallèles les unes aux autres, chacune des rainures recevant un ou plusieurs des organes de contention 40A à 40D.According to a variant not shown, each
Les lamelles 38 sont flexibles radialement, c'est-à-dire que leurs extrémités distales 54 sont susceptibles de s'approcher ou de s'éloigner radialement de l'axe d'insertion D.The
Dans la position non insérée, les lamelles 38 sont par exemple légèrement recourbées vers l'axe d'insertion D à mesure que l'on s'approche de leurs extrémités distales 54.In the non-inserted position, the
Les lamelles 38 et les organes de contention 40A à 40D étant flexibles, les extrémités distales 54 définissent une ouverture distale du logement 14 ayant un diamètre D2 plus petit dans la position non insérée que dans la position insérée.The
Dans la position non insérée, les fentes 50 présentent par exemple une longueur, suivant l'axe d'insertion D, comprise entre 5 mm et 80 mm, et une largeur, dans le sens circonférentiel, comprise entre 0,2 mm et 2,5 mm.In the non-inserted position, the
Dans la position insérée, les lamelles 38 ont des faces 56 radialement intérieures plaquées contre la partie insérable 12.In the inserted position, the
Les organes de contention 40A à 40D sont adaptés pour exercer une pression radiale centripète sur les lamelles 38 dans la position insérée.The
Dans l'exemple représenté, il n'y qu'une seule pluralité 40 d'organes de contention structurellement analogues les uns aux autres.In the example shown, there is only one
Selon des variantes non représentées, il existe plusieurs pluralités, ou séries, d'organes de contention analogues les uns aux autres à l'intérieur d'une même série, mais pas d'une série à l'autre.According to variants not shown, there are several pluralities, or series, of restraining devices similar to each other within the same series, but not from one series to another.
Toujours dans l'exemple représenté, les organes de contention 40A à 40D sont au nombre de quatre.Still in the example shown, the
Selon des variantes non représentées, le nombre des organes de contention est de deux (notamment s'il y a quatre lamelles), trois (notamment s'il y a six lamelles), six (s'il y a dix lamelles), ou huit (s'il y a douze lamelles).According to variants not shown, the number of restraining devices is two (especially if there are four strips), three (especially if there are six strips), six (if there are ten strips), or eight (if there are twelve coverslips).
Avantageusement, le nombre d'organes de contention est supérieur ou égal au nombre de lamelles 38 divisé par deux.Advantageously, the number of restraining members is greater than or equal to the number of
Chacun des organes de contention comprend par exemple une lame 58 (
Chacun des organes de contention 40A à 40D est avantageusement constitué d'une matière ayant un coefficient de dilatation thermique inférieur à celui des lamelles 38 du contact femelle 10, et inférieur à celui de la partie insérable 12 du contact mâle 5.Each of the
Par exemple, les organes de contention 40A à 40D sont en acier inoxydable, avec un coefficient de dilatation thermique de 14.10-6 K-1. Les lamelles 38 et la partie insérable 12, si elles sont en aluminium, ont un coefficient de dilatation thermique de 23.10-6 K-1.For example, the restraining
L'interruption 60 mesure par exemple entre 0,1 mm et 3 mm dans le sens circonférentiel. L'interruption 60 est propre à conférer à chacun des organes de contention 40A à 40D une élasticité adaptée pour maintenir les lamelles 38 plaquées sur la partie insérable 12.
Comme visible sur la
En variante, les organes de contention 40A à 40D présentent d'autres formes qu'une lame recourbée en « C », mais dissymétriques autour de l'axe d'insertion D, de manière à toujours définir une orientation angulaire autour de cet axe.As a variant, the
Dans l'exemple représenté, les organes de contention 40A à 40D sont décalés, successivement selon l'axe d'insertion, d'un angle α valant 90° par rapport au précédent.In the example shown, the
Selon des variantes non représentées, les décalages angulaires ne sont pas successifs (c'est-à-dire que les organes de contention sont placés dans un ordre différent selon l'axe d'insertion D), ou ne sont pas identiques (c'est-à-dire qu'ils ont des valeurs différentes de 90°).According to variants not shown, the angular shifts are not successive (that is to say that the compression members are placed in a different order along the insertion axis D), or are not identical (it that is, they have values other than 90 °).
Avantageusement, chaque décalage angulaire est sensiblement égal à 360° divisé par N, N étant le nombre d'organes de contention dans la pluralité.Advantageously, each angular offset is substantially equal to 360 ° divided by N, N being the number of restraints in the plurality.
L'épaisseur des lames 58 est par exemple comprise entre 0,5 mm et 3 mm dans le sens radial.The thickness of the
La bague 36 définit un logement 62 axialement traversant qui reçoit la portion de câble électrique 24. La bague comprend une embase 64, et une enveloppe 66 s'étendant axialement à partir de l'embase et configurée pour entourer la portion de câble électrique 28.The
L'embase 64 et la partie conductrice 28 de la portion de câble électrique 24 forment une face 68 soudée par friction au corps 34. Dans l'exemple représenté, cette face 68 est perpendiculaire à l'axe d'insertion D.The
L'enveloppe 66 est adaptée pour être sertie de manière étanche sur la portion de câble électrique 28. Comme visible sur les
La partie principale 72 est avantageusement plus épaisse radialement que le collier de sertissage 74.The
Le collier de sertissage 74 définit avantageusement une rainure 76 intérieure s'étendant autour de l'axe d'insertion D et dans laquelle se trouve un joint torique 78 pour assurer l'étanchéité entre la bague 36 et la gaine isolante 32.The crimping
Selon une variante représentée sur la
Outre la partie insérable 12, le contact mâle 5 comporte un corps 82 électriquement conducteur, et une bague 84 prévue pour recevoir la portion de câble électrique 22.In addition to the
La partie insérable 12 fait saillie axialement à partir du corps 84.The
La partie insérable 12 comprend une portion de contact 86 adaptée pour être en contact avec les lamelles 38 dans la position insérée, et l'extrémité distale 20 déjà évoquée plus haut.The
Avantageusement, la partie insérable 12 définit aussi un logement axial 88 débouchant sur l'extrémité distale 20 et adapté pour recevoir le deuxième isolant 18 (
La portion de contact 86 comporte une surface radialement extérieure 90 cylindrique.The
En variante (non représentée), la surface radialement extérieure 90 est tronconique.Alternatively (not shown), the radially
Dans l'exemple, la bague 84 du contact mâle 5 est analogue à la bague 36 du contact femelle 10 et ne sera pas décrite en détail.In the example, the
Selon une variante non représentée, la bague 36, 84 de l'un ou l'autre du contact mâle 5 et du contact femelle 10 est remplacée par une cosse fixée sur le corps du contact en question, par exemple à l'aide d'une vis.According to a variant not shown, the
Comme visible sur la
Les attaches 94 forment avantageusement des barreaux fixés sur le socle 68 et orientés sensiblement axialement. Le premier isolant 16 présente ainsi l'aspect d'une cage cylindrique.The
Le doigt 98 est situé sensiblement au centre du logement 14 en vue selon l'axe d'insertion D lorsque le premier isolant 16 est inséré dans le logement. Le doigt 98 comporte une extrémité distale 100 sensiblement située au centre de l'anneau 92. Le doigt 98 est par exemple sensiblement cylindrique.The
Le deuxième isolant 18 (
Le logement 106 est adapté pour recevoir le doigt 98 du premier isolant 16 dans la position insérée du connecteur électrique 1.The
Le fonctionnement du connecteur 1 se déduit de sa structure et va être brièvement décrit ci-après.The operation of the
Lorsque le connecteur électrique 1 est en fonctionnement, les portions de câble électrique 22, 24 sont reçues dans les logements 62 des bagues 36, 84.When the
Pour ce faire, les portions de câble électrique 22, 24 sont introduites dans les logements 62 définis par les bagues. Le corps 34 du contact femelle 10 est soudé par friction à la face 68 formée par la partie conductrice 28 de la portion de câble électrique 24 et par l'embase 64 de la bague 36. De même, le corps 82 du contact mâle 5 est soudé par friction à la face formée par la partie conductrice 26 de la portion de câble électrique 22 et par l'embase de la bague 84.To do this, the portions of
Le premier isolant 16 et le deuxième isolant 18 sont avantageusement insérés respectivement dans le contact femelle 10 et le contact mâle 5 selon l'axe d'insertion D.The
Pour ce faire, les attaches 94 sont insérées dans les fentes 50 jusqu'à ce que l'anneau 92 masque les extrémités distales 54 des lamelles 38. Le socle 96 est alors fixé sur le corps 34 par coincement, ou en variante par encliquetage.To do this, the
Pour installer le deuxième isolant électrique 18, la tige 104 est introduite dans le logement 88 de la partie insérable 12 selon l'axe d'insertion D, jusqu'à ce que la tête 102 recouvre l'extrémité distale 20.To install the second
Le connecteur électrique 1 est alors prêt à l'usage.The
On rappelle que les gaines extérieures (non représentées) protègent l'opérateur contre tout contact intempestif dans le sens radial avec le contact mâle 5 ou le contact femelle 10.It will be recalled that the external sheaths (not shown) protect the operator against inadvertent contact in the radial direction with the
Le premier isolant électrique 16 protège des extrémités distales 54 du contact femelle 10. L'anneau 92 et le doigt 98 coopèrent pour empêcher l'opérateur d'introduire son doigt dans le logement 14. Toutefois, grâce à sa structure en forme de cage, le premier isolant électrique 16 n'empêche pas le contact électrique entre les lamelles 38 et la surface radialement extérieure90 de la portion de contact 86 de la partie insérable 12.The first
De même, le deuxième isolant électrique 18 empêche l'opérateur de toucher l'extrémité distale 20 de la partie insérable 12.Likewise, the second
Le contact électrique 1 est alors mis dans la position insérée représentée sur les
Le contact mâle 5 est inséré dans le logement 14 selon l'axe d'insertion D. La portion de contact 86 pénètre dans le logement 14, ce qui provoque un écartement radial des extrémités distales 54 des lamelles 38. Cet écartement radial est limité par l'action des organes de contention 40A à 40D.The
Lors de l'insertion, le doigt 98 du premier isolant électrique 16 pénètre dans le logement 106 du deuxième isolant électrique 18, de sorte que les isolants électriques 16, 18 ne font pas obstacle à l'insertion.During insertion, the
Pendant l'insertion, chacun des organes de contention 40A à 40D se dilate, tout en appliquant une pression centripète sur les lamelles 38. Cette pression contribue à plaquer les faces radialement intérieures 56 des lamelles 38 sur la portion de contact 86 de la partie insérable 12.During insertion, each of the
Comme les organes de contention 40A à 40D ne présentent pas une symétrie de révolution autour de l'axe d'insertion D, leurs actions individuelles sur la partie insérable 12 ne sont pas uniformes angulairement.As the
Toutefois, grâce à la présence de plusieurs organes de contention et à leur décalage angulaire, l'action globale des organes de contention 40A à 40D est plus homogène angulairement que s'il n'y avait par exemple qu'un seul organe de contention.However, thanks to the presence of several compression devices and their angular offset, the overall action of the
Dans la position insérée représentée, les lamelles 38 sont donc mieux plaquées sur la portion de contact 86, dont elles épousent la surface radialement extérieure 90. La résistance du connecteur électrique 1 est donc diminuée.In the inserted position shown, the
Grâce aux bagues 36, 84 soudées par friction, la résistance électrique du connecteur électrique 1, mesurée sur une longueur L entre les embases des bagues, est quasiment égale à celle de la partie conductrice de portions de câble électrique sur cette même longueur.Thanks to the
En cas d'échauffement du connecteur électrique 1, par exemple par effet Joule, les organes de contention 40A à 40D se dilatent moins et exercent une pression radiale centripète plus forte sur les lamelles 38 qu'à l'état non chauffé. Ceci a pour conséquence une augmentation de la pression exercée par lamelles 38 sur la partie insérable 12, et une augmentation de la surface de contact entre les lamelles et la partie insérable. Ceci réduit la résistance de contact et entraîne une diminution de l'échauffement du connecteur électrique 1 pendant l'utilisation.In the event of heating of the
Dans la position insérée, le connecteur électrique 1 présente une grande stabilité mécanique grâce à la structure des lamelles 38 et à l'action des organes de contention 40A à 40D. En outre, l'insertion du contact mâle 5 dans le contact femelle 10 reste très facile du fait de la flexibilité des lamelles 38 et de l'élasticité des organes de contention 40A à 40D.In the inserted position, the
Le connecteur électrique 1 est de ce fait extrêmement performant, tant en ce qui concerne la facilité d'insertion, que la tenue aux vibrations.The
Le connecteur électrique 1 présente un faible encombrement par rapport à ses performances électriques.The
Du fait de sa structure relativement simple, sans interface, le connecteur électrique 1 reste d'une fabrication simple et d'un prix compétitif.Due to its relatively simple structure, without interface, the
Grâce aux isolants électriques 16, 18, l'opérateur est protégé pendant la manipulation du connecteur électrique 1.Thanks to the
En référence à la
Le corps 34 du contact femelle 110 définit une gorge 112 s'étendant autour de l'axe d'insertion D et débouchant dans le logement 14. Axialement la gorge 112 s'étend entre le fond 44 du logement 14 et les lamelles 38.The
Dans l'exemple représenté, la gorge 112 est délimitée axialement, du côté de la bague 36 (non représentée sur la
La gorge 112 est adaptée pour affaiblir, par amincissement, le corps 34 à la base des lamelles 38. Ceci permet de réduire l'effort d'insertion du contact mâle 5 en réduisant le moment de flexion de 10% sans pour autant dégrader le fonctionnement électrique du connecteur 1.The
Dans cet exemple, le contact femelle 10 comprend huit lamelles 38, et il y a quatre organes de contention 40A à 40D, comme représenté sur la
Les dimensions des lamelles sont, par exemple : longueur : 33 mm ; largeur 5,70 mm, hauteur : 3,5 mm.The dimensions of the slats are, for example: length: 33 mm; width 5.70 mm, height: 3.5 mm.
On a d'abord testé un premier agencement, non représenté et non conforme à l'invention, dans lequel les quatre organes de contention ne présentent aucun décalage angulaire entre eux. Les interruptions 60 de chaque lame en « C » sont axialement alignées avec la fente 52 située entre les lamelles 38.1 et 38.2. Ce premier agencement se déduit de la
Dans ce premier agencement, on obtient une surface de contact totale de 70 mm2 entre les huit lamelles et la partie insérable 12 du contact mâle 5. Cette surface de contact se répartit de façon non homogène sur les huit lamelles de la façon suivante :
- lamelle 38.1 : 17%,
- lamelle 38.2 : 15%,
- lamelle 38.3 : 10%,
- lamelle 38.4 : 8%,
- lamelle 38.5 : 8%,
- lamelle 38.6 : 10%,
- lamelle 38.7 : 15%,
- lamelle 38.8 : 17%.
- coverslip 38.1: 17%,
- coverslip 38.2: 15%,
- coverslip 38.3: 10%,
- coverslip 38.4: 8%,
- slat 38.5: 8%,
- coverslip 38.6: 10%,
- slat 38.7: 15%,
- coverslip 38.8: 17%.
Puis on a testé un deuxième agencement, représenté sur la
Dans ce deuxième agencement, on obtient une surface de contact totale de 100 mm2 entre les huit lamelles et la partie insérable 12 du contact mâle 5. Cette surface de contact est bien meilleure dans le premier agencement non conforme à l'invention. De plus, la surface de contact se répartit de façon beaucoup plus homogène sur les huit lamelles de la façon suivante :
- lamelle 38.1 : 12,5%,
- lamelle 38.2 : 13,0%,
- lamelle 38.3 : 12,5%,
- lamelle 38.4 : 12,0%,
- lamelle 38.5 : 12,0%,
- lamelle 38.6 : 12,5%,
- lamelle 38.7 : 13,0%,
- lamelle 38.8 : 12,5%.
- coverslip 38.1: 12.5%,
- coverslip 38.2: 13.0%,
- coverslip 38.3: 12.5%,
- coverslip 38.4: 12.0%,
- coverslip 38.5: 12.0%,
- coverslip 38.6: 12.5%,
- coverslip 38.7: 13.0%,
- coverslip 38.8: 12.5%.
La répartition homogène permet d'avoir un comportement homogène lors du fonctionnement des lamelles (même pression de contact pour chaque lamelle avec le contact mâle). Cela améliore les performées électriques, la durée de vie du connecteur et la tenue aux vibrations (suppression du risque de perte du contact).The homogeneous distribution makes it possible to have a homogeneous behavior during the operation of the slats (same contact pressure for each slat with the male contact). This improves electrical performance, the life of the connector and resistance to vibrations (elimination of the risk of loss of contact).
Comme on peut le constater, les décalages angulaires à 360°/N, N étant le nombre d'organes de contention, ont permis d'augmenter la surface de contact et ont rendu sa répartition sur les lamelles plus homogène.As can be seen, the angular offsets at 360 ° / N, N being the number of restraining members, have made it possible to increase the contact surface and have made its distribution over the strips more homogeneous.
D'autres tests ont montré que des bénéfices apparaissent dès qu'il existe un décalage angulaire entre deux des organes de contention.Other tests have shown that benefits appear as soon as there is an angular offset between two of the restraints.
