Description

La présente invention a pour objet un contact à ressort pour connecteur électrique de volume réduit ainsi qu'un connecteur comportant un tel contact. Elle trouve plus particulièrement son utilisation dans le domaine des télécommunications, notamment dans le cadre de la miniaturisation des téléphones portables. Ce type de contact est généralement mais non exclusivement utilisé pour relier, de manière réversible, une batterie et un circuit imprimé situés à l'intérieur d'un téléphone portable. Plus généralement, ce type de contact est destiné à relier électriquement deux équipements quelconques. Actuellement, ce contact à ressort est soudé par une première extrémité en surface sur un circuit imprimé, et présente à une deuxième extrémité une languette souple qui est recourbée au-dessus de la première extrémité. Cette languette souple peut venir notamment au contact des plots d'une batterie présentée au-dessus du connecteur contenant les contacts.The present invention relates to a spring contact for connector electrical device of reduced volume as well as a connector comprising such a contact. It finds more particularly its use in the field of telecommunications, particularly in the context of the miniaturization of mobile phones. This type of contact is generally but not exclusively used to reversibly connect a battery and a circuit board located inside a cell phone. More generally, this type of contact is intended to electrically connect two devices any. Currently, this spring contact is welded by a first surface end on a printed circuit, and present at a second end a flexible tongue which is curved above the first end. This flexible tongue can come in particular into contact with the studs a battery presented above the connector containing the contacts.

Les connecteurs montés dans les téléphones portables, ont une forme globalement parallélépipédique. Ce type de connecteur comporte des logements ou compartiments, qui contiennent les contacts à ressort. Ces logements débouchent d'une part sur une première face, dite inférieure, et d'autre part sur une deuxième face, dite supérieure, du connecteur. La face inférieure vient en contact sur un circuit imprimé et la face supérieure vient en contact sur la batterie. Un contact à ressort, inséré dans ce logement, a une forme sensiblement en U présentant deux branches ou bras, et une base ou coude du U, reliant les deux branches par l'une de leur extrémité. La base du U a une forme d'arc de cercle et s'étend dans un plan perpendiculaire aux plans des première et deuxième face du connecteur. Chaque branche est destinée à établir un contact électrique avec un équipement.The connectors mounted in mobile phones have a shape broadly parallelepiped. This type of connector includes housings or compartments, which contain the spring contacts. These housings lead on the one hand to a first face, called the lower face, and on the other hand on a second face, called the upper face, of the connector. The face lower comes into contact on a printed circuit and the upper face comes contact on the battery. A spring contact, inserted in this housing, has a substantially U-shaped with two branches or arms, and a base or elbow of the U, connecting the two branches by one of their ends. The basis of U has the shape of an arc of a circle and extends in a plane perpendicular to the first and second faces of the connector. Each branch is intended for establishing electrical contact with equipment.

La première branche du U est fixée, par exemple soudée, à un circuit imprimé placé contre la première face du connecteur. La deuxième branche forme une bosse dépassant de la deuxième face du connecteur.The first branch of the U is fixed, for example soldered, to a circuit printed against the first side of the connector. The second branch forms a bump protruding from the second face of the connector.

La hauteur totale du U est formée par l'addition de trois hauteurs. Ces hauteurs sont définies par la distance la plus courte séparant deux plans, parallèles au plan du circuit imprimé, contenant des points du contact à ressort. Une première hauteur est constituée par la distance séparant un point de soudure de la première branche avec le circuit imprimé d'un point de jonction entre la première branche et la base. Une deuxième hauteur est égale à une corde de la base correspondant à la distance entre les deux points extrêmes constituant l'arc de cercle. Une troisième hauteur est constituée par la distance séparant un point de la deuxième branche, le plus haut par rapport à la base, d'un point de contact entre la deuxième branche et la base. Une épaisseur du connecteur est définie par la distance la plus courte reliant la première face à la deuxième face. L'épaisseur du connecteur est inférieure à la hauteur totale du contact, car le contact à ressort est prévu pour s'enfoncer partiellement à l'intérieur du logement du connecteur, lorsqu'il est contraint. Dans un exemple, un tel connecteur a une épaisseur de 3,2 millimètres.The total height of the U is formed by the addition of three heights. These heights are defined by the shortest distance between two planes, parallel to the plane of the printed circuit, containing points of contact to spring. A first height is formed by the distance between a point soldering of the first branch with the printed circuit of a point of junction between the first branch and the base. A second height is equal to a base chord corresponding to the distance between the two points extremes constituting the arc of a circle. A third height consists of the distance between a point and the second branch, the highest by relative to the base, a point of contact between the second branch and the base. A thickness of the connector is defined by the shortest distance connecting the first side to the second side. Connector thickness is less at the total height of the contact, because the spring contact is designed to partially sinking inside the connector housing, when it is constrained. In one example, such a connector has a thickness of 3.2 millimeters.

La tendance actuelle de miniaturisation des appareils électroniques, tels que les téléphones portables, conduit à une volonté de diminution de la taille des différents éléments composant ces objets. Notamment, les connecteurs inclus dans ces objets doivent être réduits, pour que leur épaisseur vaille par exemple jusqu'à 1,8 millimètres, toutes autres proportions gardées.The current trend of miniaturization of electronic devices, such than cell phones, leads to a desire to shrink in size of the various elements composing these objects. In particular, the connectors included in these objects must be reduced, so that their thickness is worth example up to 1.8 millimeters, all other proportions kept.

Dans l'état de la technique, la diminution de l'épaisseur des connecteurs et de la hauteur totale des contacts à ressort qu'ils contiennent n'est possible qu'au prix d'une augmentation significative de la largeur ou de la longueur de ces connecteurs et de ces contacts. En effet, la structure actuelle des contacts à ressort impose que la diminution de hauteur totale des contacts à ressort ne peut être obtenue qu'en jouant sur les première et troisième hauteurs du contact à ressort. Or pour conserver les caractéristiques techniques de ces contacts, la diminution des première et troisième hauteurs nécessite l'épaississement ou l'élargissement des lames de ces contacts, notamment pour la lame de la deuxième branche. Ainsi l'élargissement des lames de contact aboutit à un élargissement global du connecteur. Donc la diminution globale de volume du connecteur ne peut pas être obtenue. La structure actuelle des contacts à ressort pose donc un problème de miniaturisation de ces connecteurs.In the prior art, the reduction in the thickness of the connectors and the total height of the spring contacts they contain is only possible at the cost of a significant increase in width or the length of these connectors and contacts. Indeed, the current structure spring contacts require that the decrease in total height of the contacts spring can only be obtained by playing on the first and third heights of the spring contact. Gold to keep the characteristics techniques of these contacts, the reduction of the first and third heights requires thickening or widening of the blades of these contacts, especially for the blade of the second branch. Thus the widening of Contact blades result in an overall widening of the connector. So the overall decrease in connector volume cannot be obtained. The current structure of spring contacts therefore poses a problem of miniaturization of these connectors.

D'autre part, ce type de connecteur, pour être monté en surface sur un circuit imprimé, est appréhendé par des pipettes d'aspiration. Ces pipettes doivent être mises en contact uniquement avec des zones du connecteur ne présentant pas localement de contacts à ressort. La présence d'une telle zone, généralement en position centrale de ce type de connecteur, implique nécessairement une augmentation de la largeur du connecteur. En conséquence, ce type de connecteur est actuellement appréhendé par deux pipettes, chacune disposée à une extrémité du connecteur. Ceci représente un autre problème de difficulté de manipulation des connecteurs de la technique.On the other hand, this type of connector, to be mounted on the surface on a printed circuit, is apprehended by suction pipettes. These pipettes should only be brought into contact with areas of the connector not having locally spring contacts. The presence of such an area, generally in the central position of this type of connector, implies necessarily an increase in the width of the connector. In Consequently, this type of connector is currently apprehended by two pipettes, each arranged at one end of the connector. This represents a another problem of difficulty in handling the connectors of the technique.

L'invention a pour but de remédier aux problèmes cités en proposant un contact à ressort pour connecteur, ayant une forme sensiblement en U, présentant deux branches et une base reliant les deux branches par l'une de leur extrémité, chaque branche étant destinée à établir un contact électrique avec un équipement.
Selon l'invention, les deux branches s'étendent dans des plans divergents l'un par rapport à l'autre, l'intersection de ces deux plans étant contenue dans la base du U.The invention aims to remedy the problems cited by proposing a spring contact for connector, having a substantially U-shaped shape, having two branches and a base connecting the two branches by one of their ends, each branch being intended to establish electrical contact with equipment.
According to the invention, the two branches extend in planes divergent from one another, the intersection of these two planes being contained in the base of the U.

Le contact à ressort a alors une hauteur totale plus faible que le contact à ressort de l'art antérieur.The spring contact then has a lower overall height than the contact spring of the prior art.

Pour réduire encore la hauteur totale du contact, une des branches et la base du U sont dans le même plan.To further reduce the total height of the contact, one of the branches and the base of the U are in the same plane.

En outre, pour simplifier la connexion, le contact électrique d'au moins une des branches est positionné sur l'extrémité libre de ladite branche.In addition, to simplify the connection, the electrical contact of at least one of the branches is positioned on the free end of said branch.

Selon un deuxième aspect, l'invention concerne un connecteur électrique, muni d'une première face et d'une deuxième face opposée à la première face, et comportant au moins un logement de réception d'un contact à ressort selon l'invention. Le logement est ouvert sur les deux faces du connecteur, et le contact à ressort est positionné dans le logement de telle sorte que le plan dans lequel s'étend la base du U est sensiblement parallèle au plan des faces du connecteur.According to a second aspect, the invention relates to a connector electric, with a first face and a second face opposite the first face, and comprising at least one housing for receiving a contact spring according to the invention. The housing is open on both sides of the connector, and the spring contact is positioned in the housing so so that the plane in which the base of the U extends is substantially parallel in the plane of the connector faces.

La base reliant la première et la deuxième branche est située à l'intérieur du logement. Cette base comporte un plan de courbure qui est sensiblement parallèle aux première et deuxième faces. L'augmentation de largeur du contact à ressort implique ici une augmentation faible de la largeur du connecteur. En effet, les contacts sont disposés de telle sorte que les premières branches des contacts, sur la première face, sont en vis à vis avec des espaces intercalaires des deuxièmes branche sur la deuxième face. Ainsi le volume global du connecteur est réduit, ce qui était auparavant impossible.The base connecting the first and the second branch is located at inside the accommodation. This base has a plane of curvature which is substantially parallel to the first and second faces. The increase of width of the spring contact here implies a slight increase in width of the connector. In fact, the contacts are arranged so that the first branches of the contacts, on the first face, are opposite with intermediate spaces of the second branch on the second face. So the overall volume of the connector is reduced, which was previously impossible.

Pour assurer un bon positionnement du contact dans le logement, le connecteur comporte des moyens pour guider le contact à ressort.To ensure correct positioning of the contact in the housing, the connector includes means for guiding the spring contact.

Pour garder ce bon positionnement, il comporte en outre des moyens de maintien.To keep this good positioning, it also includes means holding.

Dans le cas où il serait nécessaire de faire appel à plusieurs connections, le connecteur comporte plusieurs logements, recevant respectivement un contact à ressort en U.In the event that it is necessary to call on several connections, the connector has several housings, receiving respectively a U-shaped spring contact.

Pour que le volume de ce connecteur reste suffisamment faible, les contacts à ressort sont positionnés dans deux logements adjacents, de façon à s'étendre suivant une direction sensiblement identique mais en sens inverse l'un par rapport à l'autre, une branche d'un contact étant adjacente à une branche du contact voisin.To keep the volume of this connector low enough, the spring contacts are positioned in two adjacent housings, so that extend in a substantially identical direction but in opposite direction relative to each other, a branch of a contact being adjacent to a neighbor contact branch.

D'autre part la disposition des branches des contacts à ressort est organisée de manière à générer une zone sans contact à ressort au milieu de la deuxième face. Cette zone peut être utilisée pour y appliquer une pipette. Ainsi le connecteur peut être appréhendé par une seule pipette d'aspiration. On the other hand, the arrangement of the branches of the spring contacts is organized so as to generate a contactless spring area in the middle of the second side. This area can be used to apply a pipette. Thus the connector can be grasped by a single suction pipette.

L'invention sera mieux comprise à la lecture de la description qui suit et à l'examen des figures qui l'accompagnent. Celles-ci ne sont présentées qu'à titre indicatif et nullement limitatif de l'invention. Les figures montrent :

  • Figure 2 : une vue en perspective d'un contact à ressort selon l'invention ;
  • Figure 3 : une vue de la face non visible sur la figure 1 du connecteur selon l'invention.
The invention will be better understood on reading the description which follows and on examining the figures which accompany it. These are presented for information only and in no way limit the invention. The figures show:
  • Figure 1: a perspective view of a connector according to the invention;
  • Figure 2: a perspective view of a spring contact according to the invention;
  • Figure 3: a view of the face not visible in Figure 1 of the connector according to the invention.

Le connecteur de l'invention comporte un corps 1, muni d'une première face 2 (visible dans la figure 1) opposée à une deuxième face 3 (visible dans la figure 3), chacune des faces s'étendant dans des plans respectivement 2.1 et 3.1. Le corps 1 comporte des logements 4 ouvert sur les deux faces. A cet effet, un logement 4 présente une première entrée 5 débouchant sur la première face 2, et une deuxième entrée 6 débouchant sur la deuxième face 3. Les deux entrées 5 et 6 sont séparées par un mur intercalaire 4.1. Le connecteur comporte des contacts à ressort 7, chacun placé dans un logement 4. Le corps 1 a une épaisseur 8. L'épaisseur 8 est préférentiellement inférieure ou égale à 1,8 mm. Le corps 1 a une largeur 9 et une longueur 10. Dans l'exemple représenté, le corps 1 comporte quatre logements 4 et quatre contacts à ressort 7. Dans ce cas, la largeur 9 est préférentiellement égale à 8,3 mm, et la longueur 10 est préférentiellement égale à 15,3 mm. Néanmoins, le connecteur selon l'invention peut comporter un ou plusieurs logements munis chacun d'un contact à ressort. Et les dimensions peuvent être adaptées en fonction du nombre de contacts à ressort ou des caractéristiques techniques requises.The connector of the invention comprises a body 1, provided with a first side 2 (visible in Figure 1) opposite a second side 3 (visible in Figure 3), each of the faces extending in planes respectively 2.1 and 3.1. The body 1 has housings 4 open on both sides. In this Indeed, a housing 4 has a first entry 5 leading to the first face 2, and a second inlet 6 leading to the second face 3. The two entrances 5 and 6 are separated by an intermediate wall 4.1. The connector has spring contacts 7, each placed in a housing 4. The body 1 has a thickness 8. The thickness 8 is preferably less or equal to 1.8 mm. The body 1 has a width 9 and a length 10. In the example shown, the body 1 has four housings 4 and four spring contacts 7. In this case, the width 9 is preferably equal to 8.3 mm, and the length 10 is preferably equal to 15.3 mm. However, the connector according to the invention may include one or more housing each provided with a spring contact. And the dimensions can be adapted according to the number of spring contacts or characteristics techniques required.

Le contact à ressort 7 présente une première branche 11 s'étendant dans un plan 11.1 et une deuxième branche 12 s'étendant dans un plan 12.1. La première branche 11 et la deuxième branche 12 sont reliées par une base 13. Les deux branches sont destinées à établir un contact électrique avec un équipement tel qu'une batterie ou un circuit imprimé. Dans le cas des téléphones portables, le contact peut être fixé à demeure au circuit imprimé par une de ses branches , ici 11, la batterie venant en contact avec l'autre branche, ici 12. La base 13 présente un plan de courbure 13.1. qui une fois le contact monté dans le connecteur, est parallèle aux plans 2.1 et 3.1 définis par les première et deuxième faces. Cependant, il peut également être oblique par rapport à ces mêmes plans. Dans ce cas, le terme plan de courbure désigne le plan dans lequel est projetée cette courbure, selon un axe perpendiculaire aux première et deuxième faces.The spring contact 7 has a first branch 11 extending in a plane 11.1 and a second branch 12 extending in a plane 12.1. The first branch 11 and the second branch 12 are connected by a base 13. The two branches are intended to establish electrical contact with a equipment such as a battery or a printed circuit. In the case of mobile phones, the contact can be permanently fixed to the printed circuit by one of its branches, here 11, the battery coming into contact with the other branch, here 12. The base 13 has a plane of curvature 13.1. who once the contact mounted in the connector, is parallel to planes 2.1 and 3.1 defined by the first and second faces. However, it can also be oblique compared to these same plans. In this case, the term plane of curvature designates the plane in which this curvature is projected, along an axis perpendicular to the first and second faces.

Selon l'invention, les deux branches 11 et 12 s'étendent dans des plans respectivement 11.1 et 12.1 divergents l'un par rapport à l'autre et l'intersection I de ces deux plans est contenue dans la base 13 du U.According to the invention, the two branches 11 and 12 extend in planes respectively 11.1 and 12.1 divergent from each other and the intersection I of these two planes is contained in the base 13 of the U.

En outre, dans l'exemple représenté, le plan 11.1 de la branche 11 et le plan 13.1 sont sensiblement confondus.In addition, in the example shown, the plan 11.1 of branch 11 and the plan 13.1 are substantially confused.

La première branche 11 a une forme rectangulaire présentant deux marches ou décrochements en baïonnette 14 et 15. Ces deux marches 14 et 15 définissent ainsi trois portions sur la première branche 11. Une première portion 16 est constituée par l'extrémité de la première branche 11. L'extrémité 16 est une extrémité libre, destinée à être reliée et notamment soudée sur un circuit imprimé. Une deuxième portion 17 située entre les marches 14 et 15 est une surface plane. La portion 17 est destinée à être maintenue dans le logement 4 du corps 1. Une troisième portion 18 est définie entre la marche 15 et la base13. La portion 18 est mobile dans un plan orthogonal au plan formé par la portion 17. La portion 18 est mobile par rapport à la portion 17 par l'intermédiaire d'une charnière formée par la marche 15. Cette marche 15 a également pour rôle de renforcer la raideur de la branche 11.The first branch 11 has a rectangular shape having two bayonet steps or steps 14 and 15. These two steps 14 and 15 thus define three portions on the first branch 11. A first portion 16 is formed by the end of the first branch 11. The end 16 is a free end, intended to be connected and in particular soldered on a printed circuit. A second portion 17 located between the steps 14 and 15 is a flat surface. The portion 17 is intended to be maintained in the housing 4 of the body 1. A third portion 18 is defined between step 15 and base 13. The portion 18 is movable in a plane orthogonal to the plane formed by the portion 17. The portion 18 is movable relative to the portion 17 by means of a hinge formed by the step 15. This step 15 also has the role of reinforcing the stiffness of branch 11.

La deuxième branche 12 comporte une première zone 19 formant épaulement et un retour 20. Une première portion 21 de la deuxième branche 12 est définie entre la zone 19 et le retour 20. La zone 19 a un rôle de charnière de la portion 21 par rapport au plan de courbure 13.1. La première portion 21 a une forme rectangulaire plane. Dans l'exemple présenté, le retour 20 et la portion 21 sont destinés à entrer en contact avec l'un des plots d'une batterie, qui sera contraint contre la branche 12, dépassant de la deuxième face 3. Le retour 20 sépare la première portion 21 d'une deuxième portion 22 de la deuxième branche 12 en formant un angle saillant, de telle sorte que la deuxième portion 22 soit recourbée légèrement sous la première portion 21. Les portions 21 et 22 de la deuxième branche 12 sont mobiles par rapport à la base 13 dans un plan perpendiculaire au plan de courbure 13.1. Par ailleurs, la branche 12 est mobile dans un plan distinct mais parallèle, au plan de mobilité de la branche 11.The second branch 12 has a first zone 19 forming shoulder and back 20. A first portion 21 of the second branch 12 is defined between zone 19 and return 20. Zone 19 has a role hinge of the portion 21 relative to the plane of curvature 13.1. The first portion 21 has a flat rectangular shape. In the example presented, the return 20 and the portion 21 are intended to come into contact with one of the studs of a battery, which will be forced against the branch 12, protruding from the second face 3. The return 20 separates the first portion 21 a second portion 22 of the second branch 12 forming an angle protruding, so that the second portion 22 is slightly curved under the first portion 21. The portions 21 and 22 of the second branch 12 are movable relative to base 13 in a plane perpendicular to the plane of curvature 13.1. Furthermore, the branch 12 is movable in a separate plane but parallel to the mobility plan of branch 11.

Une hauteur totale du contact à ressort 7 est constituée par l'addition d'une première hauteur égale à la hauteur de la première branche 11 et d'une deuxième hauteur constituée par la hauteur de la deuxième branche 12. En effet, la hauteur de la base est quasiment nulle, car sa hauteur est égale à l'épaisseur de la lame constituant le contact à ressort. Les hauteurs sont définies de manière absolue par la distance la plus courte séparant deux plans parallèles au plan 13.1. La première hauteur est égale à la somme d'une hauteur 23 correspondant à la hauteur de l'extrémité 16, d'une hauteur 24 correspondant à la hauteur de la marche 14, et d'une hauteur 25 correspondant à la hauteur de la marche 15. La deuxième hauteur est égale à une hauteur 26 de la première portion 21.A total height of the spring contact 7 is constituted by the addition of a first height equal to the height of the first branch 11 and a second height consisting of the height of the second branch 12. Indeed, the height of the base is almost zero, because its height is equal to the thickness of the blade constituting the spring contact. Heights are absolutely defined by the shortest distance between two planes parallel to the plane 13.1. The first height is equal to the sum of a height 23 corresponding to the height of the end 16, of a height 24 corresponding to the height of the step 14, and a height 25 corresponding to the height of step 15. The second height is equal to a height 26 of the first portion 21.

La deuxième portion 22 a une hauteur 27. La hauteur 27 est la plus grande possible, de manière à ce que la deuxième branche 12 ne sorte pas complètement du corps 1. Dans un autre exemple, la portion 22 peut comporter à une extrémité des pattes qui lui permettent d'être retenue dans la deuxième entrée 6.The second portion 22 has a height 27. The height 27 is the most large possible, so that the second branch 12 does not come out full body 1. In another example, the portion 22 can have tabs at one end which allow it to be retained in the second entry 6.

Comme représenté sur la figure 1, le contact à ressort 7 est maintenu dans le logement 4 du corps 1 par des moyens de maintien. Les moyens de maintien comportent des ergots 28 maintenant la portion 17 en appui contre une bordure 29 de la première entrée 5. Les ergots 28 sont par exemple des gouttes de matière plastique fondues sur le contact à ressort 7, après son positionnement dans le logement 4. Le contact à ressort 7 est introduit dans le corps 1 par la première entrée 5 de la première face 4. La taille de la première entrée 5 est telle qu'elle laisse un passage à l'intégralité du contact à ressort 7. Par contre la deuxième entrée 6 ne laisse sortir que la deuxième branche 12 du contact à ressort 7. En effet, la branche 11 est retenu dans la première entrée 5 par le mur intercalaire 4.1. Le logement 4 comporte ainsi un trou, débouchant de la première entrée 5 à la deuxième entrée 6, ayant une ouverture restreinte à la taille de l'ouverture la deuxième entrée 6 seule. Lorsqu'un objet, par exemple une batterie, est contraint sur la deuxième face 3 du corps 1, et donc contre la branche 12 des contacts à ressort 7, la branche 12 s'enfonce, la hauteur 26 diminue et la portion 22 s'enfonce dans le logement 4. Dans un exemple, la course maximale de la branche 12 est égale à 1,5 mm. L'objet appliqué contre la deuxième face 3 doit exercer une force comprise entre 0,5 et 1,5 newtons pour enfoncer une branche 12 à l'intérieur de son logement 4.As shown in Figure 1, the spring contact 7 is maintained in the housing 4 of the body 1 by holding means. The means of maintenance include lugs 28 holding the portion 17 in abutment a border 29 of the first entry 5. The pins 28 are for example plastic drops melted on the spring contact 7, after positioning in the housing 4. The spring contact 7 is introduced into the body 1 by the first entry 5 of the first face 4. The size of the first entry 5 is such that it leaves a passage to the entire contact at spring 7. On the other hand, the second entry 6 leaves only the second branch 12 of the spring contact 7. Indeed, branch 11 is retained in the first entry 5 through the intermediate wall 4.1. The housing 4 thus comprises a hole, opening from the first entry 5 to the second entry 6, having an opening restricted to the size of the opening, the second entry 6 alone. When an object, for example a battery, is forced on the second side 3 of the body 1, and therefore against the branch 12 of the spring contacts 7, the branch 12 sinks, the height 26 decreases and the portion 22 sinks into the housing 4. In an example, the maximum stroke of the branch 12 is equal at 1.5 mm. The object applied against the second face 3 must exert a force between 0.5 and 1.5 newtons to insert a branch 12 inside of his accommodation 4.

Le connecteur possède un axe de symétrie 30 orthogonal aux faces première et deuxième 2 et 3, et passant par le centre de chacune d'entre elles. L'axe de symétrie 30 est une particularité liée au nombre de contacts à ressort 7 inclus dans le corps 1. En effet l'axe de symétrie 30 existe uniquement dans les cas de figure où le connecteur possède un nombre pair de contacts à ressort 7.The connector has an axis of symmetry 30 orthogonal to the faces first and second 2 and 3, and passing through the center of each of them. The axis of symmetry 30 is a peculiarity linked to the number of spring contacts 7 included in the body 1. Indeed the axis of symmetry 30 exists only in cases where the connector has an even number of contacts to spring 7.

Dans le cas où il est nécessaire d'avoir plusieurs points de contact, le connecteur comporte plusieurs logements par exemple 4a;4b, recevant respectivement un contact à ressort 7a;7b. Les contacts sont positionnés de façon à s'étendre suivant une direction sensiblement identique mais en sens inverse l'un par rapport à l'autre, une branche 11a d'un contact 7a étant adjacente à une branche 12b du contact voisin 7b.In case it is necessary to have several points of contact, the connector has several housings for example 4a; 4b, receiving respectively a spring contact 7a; 7b. The contacts are positioned from so as to extend in a substantially identical direction but in direction reverse with respect to each other, a branch 11a of a contact 7a being adjacent to a branch 12b of the neighboring contact 7b.

L'agencement des contacts les uns par rapport aux autres dans le corps 1 est réalisé de manière à répartir alternativement les marches 20 sur la deuxième face 3. En contrepartie, de cette manière on homogénéise la répartition des extrémités 16 de part et d'autre de la première face 2. Les contacts à ressort 7 sont placés les uns à côté des autres dans le corps 1. L'espace séparant deux branches 12 successives sur la deuxième face 3 est superposé à l'emplacement, sur la première face 2, d'une branche 11 relié à l'un des deux branche 12. D'un contact 7 à un suivant, la position des extrémités 16 est alternée. En effet les extrémités 16 dépassent soit d'un premier côté 31 de la première face 2 soit d'un deuxième côté 32 opposé au côté 31 de la première face 2. Ainsi le connecteur est fixé des deux côtés 31 et 32 du circuit imprimé. Sa fixation étant plus solide, il n'est donc pas nécessaire de réaliser des soudures supplémentaires pour garantir le placement mécanique du connecteur.The arrangement of contacts in relation to each other in the body 1 is made so as to alternately distribute the steps 20 on the second side 3. In return, in this way we homogenize the distribution of the ends 16 on either side of the first face 2. The spring contacts 7 are placed next to each other in the body 1. The space separating two successive branches 12 on the second face 3 is superimposed on the location, on the first face 2, of a branch 11 connected to one of the two branches 12. From a contact 7 to a following, the position of ends 16 is alternated. Indeed the ends 16 protrude either by first side 31 of the first face 2 or a second side 32 opposite the side 31 of the first face 2. Thus the connector is fixed on both sides 31 and 32 of the printed circuit. Its fixation is more solid, so it is not necessary make additional welds to ensure placement connector mechanics.

De plus, afin de libérer une zone 33 sur la deuxième face 3, suffisante pour pointer une pipette, les contacts à ressort 7 sont disposés de manière particulière. Cette zone 33 est recherchée en position centrale. Elle permet la préhension par une pipette unique d'un diamètre d'au moins 2,5 mm.In addition, in order to free an area 33 on the second face 3, sufficient to point a pipette, the spring contacts 7 are arranged so particular. This zone 33 is sought in the central position. It allows the gripping by a single pipette with a diameter of at least 2.5 mm.

Le connecteur comporte en plus des évidements ou cavités 34. Les cavités 34 sont découpées dans deux faces latérales 35 et 36 des côtés respectivement 31 et 32 du connecteur 1. Les cavités 34 sont découpées de telle manière que des extrémités libres 16 des contacts à ressort 7 insérés dans le corps 1 dépassent des côtés 31 et 32 à l'endroit où ces cavités 34 sont aménagées. Ainsi les extrémités 16 sont visuellement accessibles depuis la deuxième surface 3 pour être soudées. La soudure des extrémités 16 sur un circuit imprimé est ainsi facilitée.The connector also has recesses or cavities 34. The cavities 34 are cut in two lateral faces 35 and 36 on the sides respectively 31 and 32 of connector 1. The cavities 34 are cut out from such that free ends 16 of the spring contacts 7 inserted in the body 1 protrude from the sides 31 and 32 at the place where these cavities 34 are fitted out. Thus the ends 16 are visually accessible from the second surface 3 to be welded. The welding of the ends 16 on a circuit board is thus facilitated.
