Description

La présente invention concerne un connecteur formant un composant pour montage en surface.The present invention relates to a connector forming a surface mount component.

Il est connu d'utiliser des connecteurs formant un composant pour montage en surface (CMS) dans le but de connecter des éléments conducteurs extérieurs avec les pistes et les composants solidaires d'un substrat.It is known to use connectors forming a surface mount component (CMS) for the purpose of connecting external conductive elements with the tracks and the components integral with a substrate.

Les éléments conducteurs extérieurs peuvent être constitués par des languettes, broches, cartes de circuit, imprimé ou d'autres substrats conducteurs pouvant provenir de directions différentes.The outer conductive elements may consist of tabs, pins, circuit boards, printed matter or other conductive substrates that may come from different directions.

Un tel connecteur est connu par exemple du document WO 00/07263 .Such a connector is known for example from the document WO 00/07263 .

Un autre connecteur est connu du document US 5 709 574 . Ce dernier comporte
une base plane destinée à être fixée sur un substrat,
au moins deux pattes élastiques liées à la base, situées au dessus de celle-ci, et destinées à former entre elles un emplacement de serrage pour un élément conducteur,
au moins une ouverture étant ménagée dans la base, agencée pour le passage d'un élément conducteur destiné à être serré entre les pattes élastiques,
une zone de préhension par une buse de succion formée par une portion de la base plane accessible par le dessus du connecteur.Another connector is known from the document US 5,709,574 . The latter includes
a flat base intended to be fixed on a substrate,
at least two elastic tabs connected to the base, located above the latter, and intended to form between them a clamping position for a conductive element,
at least one opening being provided in the base, arranged for the passage of a conductive element intended to be clamped between the elastic tabs,
a gripping area by a suction nozzle formed by a portion of the flat base accessible from above the connector.

Le but de la présente invention est de fournir un connecteur dont la conception soit adaptée au cycle automatique de préhension / placement / soudage en refusion des lignes d'assemblage CMS à hautes cadences.The object of the present invention is to provide a connector whose design is adapted to the automatic cycle of gripping / placement / reflow soldering of CMS assembly lines at high speeds.

A cet effet, l'invention concerne un connecteur du type précité, caractérisé en ce que la zone de préhension est située entre les pattes élastiques, de façon centrée par rapport à la base du connecteur, chaque ouverture étant située latéralement par rapport à la zone de préhension.To this end, the invention relates to a connector of the aforementioned type, characterized in that the gripping zone is located between the elastic tabs, centrally relative to the base of the connector, each opening being located laterally with respect to the zone grasping.

Cette disposition permet de satisfaire les contraintes des opérations de placement des connecteurs par des buses à une cadence élevée. En effet; lors de la manipulation des buses, celles-ci peuvent être soumises à des mouvements de rotation avec des accélérations importantes: Il convient dans ces conditions que la masse du connecteur soit répartie de façon équilibrée autour de l'axe de rotation, qui correspond à l'axe de la buse.This arrangement makes it possible to meet the constraints of the operations of placement of the connectors by nozzles at a high rate. Indeed; when handling the nozzles, these can be subjected to rotational movements with significant accelerations: it is appropriate in these conditions that the mass of the connector is distributed in a balanced manner around the axis of rotation, which corresponds to the axis of the nozzle.

Selon un mode de réalisation, au moins un évidement est ménagée dans au moins une patte élastique, permettant l'accès d'une buse de succion à la zone de préhension.According to one embodiment, at least one recess is formed in at least one elastic tab, allowing access of a suction nozzle to the gripping zone.

Cette disposition permet l'accès à la zone de préhension par le dessus du connecteur, tout en conservant des dimensions latérales du connecteur et un écartement des pattes élastiques limités.This arrangement allows access to the gripping zone from above the connector, while maintaining lateral dimensions of the connector and a spacing limited elastic tabs.

Selon un mode de réalisation, deux flancs latéraux relient la base aux deux pattes élastiques, les deux pattes élastiques étant convergentes vers la base à partir des parties supérieures des flancs, en direction de l'emplacement de serrage.According to one embodiment, two lateral flanks connect the base to the two elastic tabs, the two resilient tabs converging towards the base from the upper parts of the flanks, in the direction of the clamping location.

Ainsi, les pattes élastiques sont repliés vers la base à l'intérieur des deux flancs avec un angle qui rapproche les deux parois des pattes élastiques en vis-à-vis et autorise leur flexion pour assurer des contacts de qualité sur une plage importante d'épaisseurs d'éléments conducteurs mâles.Thus, the elastic tabs are folded towards the base inside the two sides with an angle that brings the two walls closer to the elastic tabs vis-à-vis and allows their bending to ensure quality contacts over a large range of thicknesses of male conductive elements.

Avantageusement, les parois intérieures des pattes élastiques tournées vers l'emplacement de serrage présentent des bords latéraux divergents formant un évasement latéral de l'emplacement de serrage vers l'extérieur du connecteur.Advantageously, the inner walls of the resilient tabs facing the clamping location have diverging lateral edges forming a lateral flare of the clamping position towards the outside of the connector.

Cette disposition permet de faciliter l'entrée latérale d'un élément conducteur de type contact mâle. De plus la réalisation de ce bord sur une hauteur et une largeur suffisantes referme au moins partiellement le tunnel latéral formé entre chaque patte élastique, le flanc auquel elle est attachée et la base, réduisant ainsi le risque d'enchevêtrement des connecteurs dans un bol vibrant.This arrangement facilitates the lateral entry of a conductive element of the male contact type. Moreover, the realization of this edge over a sufficient height and width at least partially closes the lateral tunnel formed between each elastic tab, the side to which it is attached and the base, thus reducing the risk of entanglement of the connectors in a vibrating bowl. .

Selon un mode de réalisation, les parois intérieures des pattes élastiques tournées vers l'emplacement de serrage présentent des bords inférieurs divergents, formant un évasement vers la base de l'emplacement de serrage.According to one embodiment, the inner walls of the resilient tabs facing the clamping location have diverging lower edges, forming a flare towards the base of the clamping location.

Cet évasement permet de faciliter l'introduction d'un élément conducteur de type contact mâle par le dessous du contacteur, à travers une ouverture de la base.This flare makes it easier to introduce a conductive element of the male contact type from below the contactor, through an opening in the base.

Selon un mode de réalisation, l'évidement s'étend jusqu'au bord inférieur de la patte élastique, séparant celle-ci en deux sous parties élastiques.According to one embodiment, the recess extends to the lower edge of the elastic tab, separating it into two elastic portions.

Cette disposition permet de ménager deux emplacements de serrage distincts permettant d'accueillir deux éléments conducteurs distincts, de type contact mâle, simultanément.This arrangement allows to provide two separate clamping locations to accommodate two separate conductive elements, male contact type, simultaneously.

Avantageusement, le connecteur comporte au moins une encoche de centrage sur la base ou à proximité de celle-ci.Advantageously, the connector comprises at least one centering notch on the base or near it.

Les encoches de centrage permettent de positionner le connecteur sur le substrat ou par rapport à une buse de succion en utilisant des ergots de positionnement destinés à pénétrer au moins partiellement dans les encoches de centrage.The centering notches allow the connector to be positioned on the substrate or with respect to a suction nozzle by using positioning pins intended to penetrate at least partially into the centering notches.

Selon un premier mode de réalisation représenté sur les figures 1 à 6, un connecteur CMS 2 selon l'invention est réalisé en une seule pièce. Il comporte une base plane 3 rectangulaire destinée à être fixée sur un substrat 4, deux flancs latéraux 5 s'étendant sensiblement perpendiculairement à la base 3, au dessus de la base 3, à partir de deux côtés opposés de la base 3. A partir des extrémités supérieures des deux flancs 5 s'étendent deux pattes élastiques 6 obliques et convergentes vers le bas destinées à former entre elles un emplacement de serrage 7 pour un élément conducteur 8.According to a first embodiment shown on the Figures 1 to 6 , a CMS connector 2 according to the invention is made in one piece. It comprises a flat rectangular base 3 intended to be fixed on a substrate 4, two lateral flanks 5 extending substantially perpendicular to the base 3, above the base 3, from two opposite sides of the base 3. From the upper ends of the two sides 5 extend two oblique and convergent downwardly flexible tabs 6 intended to form between them a clamping position 7 for a conductive element 8.

Les parois intérieures des pattes élastiques 6, tournées vers l'emplacement de serrage 7 présentent des bords latéraux divergents 9 formant un évasement latéral de l'emplacement de serrage 7 vers l'extérieur du connecteur 2, vu en coupe selon un plan parallèle à la base 3. Ces parois intérieures présentent également des bords inférieurs divergents 10 formant un évasement vers le bas, à partir de l'emplacement de serrage 7, vu en coupe selon un plan perpendiculaire à la base 3.The inner walls of the resilient tabs 6 facing the clamping location 7 have diverging lateral edges 9 forming a lateral flare of the clamping position 7 towards the outside of the connector 2, seen in section along a plane parallel to the base 3. These inner walls also have diverging lower edges 10 forming a downward flare, from the clamping location 7, seen in section along a plane perpendicular to the base 3.

La base 3 présente des ouvertures latérales 12 réalisées par découpe afin de permettre le passage d'un élément conducteur 8 entrant par le dessous, à travers un perçage du substrat et destiné à être serré entre les deux pattes élastiques 6, au niveau de l'emplacement de serrage 7, ainsi que représenté sur la figure 4. Ces ouvertures 12 débouchent sur les deux bords latéraux de la base 3.The base 3 has lateral openings 12 made by cutting to allow the passage of a conductive element 8 entering from below, through a piercing of the substrate and intended to be clamped between the two elastic tabs 6, at the level of the clamping location 7, as shown in FIG. figure 4 . These openings 12 open on the two lateral edges of the base 3.

Le centre de la base 3 du connecteur, entre les ouvertures latérales 9 constitue une zone de préhension 13 par succion. La zone de préhension est accessible par une buse de succion 14 par le dessus du connecteur, entre les pattes élastiques 6. A cet effet, des évidements 15 sont ménagées dans les pattes élastiques 6, permettant l'accès d'une buse de succion 14 à la zone de préhension 13 par le dessus du connecteur 2 avec un jeu suffisant, comme représenté sur la figure 3. Les évidements 15 s'étendent jusqu'à l'extrémité libre de la pattes élastiques 6, séparant celle-ci en deux sous parties élastiques indépendantes.The center of the base 3 of the connector between the lateral openings 9 constitutes a grip zone 13 by suction. The gripping zone is accessible by a suction nozzle 14 from above the connector, between the elastic tabs 6. For this purpose, recesses 15 are formed in the elastic tabs 6, allowing access to a suction nozzle 14 to the gripping zone 13 from above the connector 2 with sufficient clearance, as shown in FIG. figure 3 . The recesses 15 extend to the free end of the elastic tabs 6, separating the latter in two independent elastic parts.

Selon un second mode de réalisation, représenté sur la figure 7, et comprenant les mêmes éléments que le premier mode de réalisation, les deux flancs latéraux 5 du connecteur 16 comportant des encoches de centrage 17 ménagées à proximité de la base, réalisées par découpe. Les encoches présentent un profil triangulaire, particulièrement adapté au centrage. Ces encoches 17 sont disposées de façon symétrique par rapport à la base 3.According to a second embodiment, represented on the figure 7 , and comprising the same elements as the first embodiment, the two lateral flanks 5 of the connector 16 having centering notches 17 formed near the base, made by cutting. The notches have a triangular profile, particularly suitable for centering. These notches 17 are arranged symmetrically with respect to the base 3.

Selon un troisième mode de réalisation, représenté sur la figure 8, un connecteur 18 comprend les mêmes éléments que dans le premier mode de réalisation, à l'exception de l'évasement latéral de l'emplacement de serrage.According to a third embodiment, represented on the figure 8 , a connector 18 comprises the same elements as in the first embodiment, with the exception of the lateral flare of the clamping location.

Selon un quatrième mode de réalisation, représenté sur la figure 9, un connecteur 19 comprend les mêmes éléments que dans le troisième mode de réalisation, à l'exception du fait que les évidements 20 ne coupent pas le bord inférieur 10 des pattes élastiques 6. Les dimensions de ces évidements sont variables en fonction des gammes d'intensité nécessaires et des épaisseurs des contacts mâles.According to a fourth embodiment, shown in the figure 9 a connector 19 comprises the same elements as in the third embodiment, with the exception that the recesses 20 do not intersect the lower edge 10 of the elastic tabs 6. The dimensions of these recesses are variable depending on the ranges of FIG. intensity required and thicknesses of the male contacts.

Selon un cinquième mode de réalisation représenté sur la figure 10, un connecteur 22 comprend les mêmes éléments que dans le troisième mode de réalisation à l'exception du fait qu'il ne comprend pas d'évidements dans les pattes élastiques. Il s'agit d'un connecteur pour des éléments conducteurs de type contacts mâles plus épais que ceux utilisés avec les quatre premiers modes de réalisation du connecteur.According to a fifth embodiment shown on the figure 10 , a connector 22 comprises the same elements as in the third embodiment except that it does not include recesses in the elastic tabs. This is a connector for thicker male-type conductor elements than those used with the first four embodiments of the connector.

Selon un sixième mode de réalisation représenté en figure 11, un connecteur 23 comprend les mêmes éléments que dans le cinquième mode de réalisation, les flancs 5 comportant toutefois des bords latéraux concaves 24, de manière à former un rétrécissement de ceux-ci au niveau de leur zone médiane. Un tel rétrécissement 24 favorise l'élasticité des flancs 5 et, par conséquent, des pattes élastiques 6 qui leur sont rattachées.According to a sixth embodiment represented in figure 11 a connector 23 comprises the same elements as in the fifth embodiment, the sidewalls 5 however having concave lateral edges 24, so as to form a narrowing thereof at their central zone. Such narrowing 24 promotes the elasticity of the sidewalls 5 and, therefore, elastic tabs 6 attached thereto.

Dans les modes de réalisations présentés ci-dessus, Le connecteur est constitué par une pièce découpée puis pliée selon un cycle d'opérations successives permettant d'obtenir les angles nécessaires.In the embodiments presented above, the connector is constituted by a cut piece and folded according to a cycle of successive operations to obtain the necessary angles.

La surface de contact du connecteur 2, par la base 3, avec le substrat 4 est importante et garantit une soudure robuste et la stabilité du connecteur 2 sur le substrat.The contact surface of the connector 2, by the base 3, with the substrate 4 is important and guarantees a robust weld and the stability of the connector 2 on the substrate.

L'amenée des contacts en position de préhension automatique par les buses 14 se fait par un outillage spécifique placé en lieu et place d'une alimentation par un distributeur de composant, cet outillage étant alimenté par un bol vibrant. Plusieurs outillages spécifiques peuvent être montés afin d'augmenter les cadences de report CMS.The supply of the contacts in the automatic gripping position by the nozzles 14 is done by a specific tool placed instead of a supply by a component distributor, this tool being fed by a vibrating bowl. Several specific tools can be mounted to increase CMS reporting rates.

Les composants peuvent être mis en bandes pour composants CMS, moyennant un surcoût.The components can be striped for SMD components at an extra cost.

La matière de ces contacts peut varier selon les applications, ce peut être par exemple du bronze étamé en bande, conforme aux normes de réduction des substances dangereuses. La finition étamée est adaptée au soudage en refusion.The material of these contacts can vary according to the applications, it can be for example strip-tinned bronze, in conformity with the standards of reduction of the dangerous substances. The tinned finish is suitable for reflow soldering.

La réalisation très simple de ce connecteur permet des productions en volume à faible coût.The very simple realization of this connector allows volume productions at low cost.
