Abstract

A connector for connecting a mother board to a daughter board, both having contacts arranged in a staggered fashion, comprises an insulating body having a channel for receiving the edge of the daughter board and passages for the penetration of flat electrical-connection terminals between corresponding contact areas on the two boards. Each terminal has means for catching on the insulation and a flexible arm intended to slide on one face of the daughter board during the insertion of the latter and to bear on a respective contact area. Every other contact terminal includes catching means (32) which can be snapped onto the insulating body by insertion parallel to the direction of engagement of the second board in the connector, whereas the other contact terminals (22a) can be snapped onto the insulating body by movement orthogonal to the direction of engagement of the second board (16) in the connector. <IMAGE>

Description

La présente invention a pour objet un connecteur destiné au raccordement entre une première carte de circuit imprimé, dite carte mère, et une seconde carte, disposée orthogonalement à la première, souvent qualifiée de carte fille, les deux cartes étant munies de rangées de plages de contact disposées en quinconce, ledit connecteur comprenant un corps isolant dans lequel sont ménagés un couloir de réception de la tranche de la deuxième carte et des passages de traversée de bornes plates de liaison électrique entre contacts correspondants des deux cartes, chacune des bornes ayant des moyens d'accrochage sur le corps isolant et un bras souple destiné à glisser sur l'autre carte lors de l'insertion de celle-ci et à s'appuyer sur une plage de contact respective.The subject of the present invention is a connector intended for the connection between a first printed circuit board, called the motherboard, and a second board, arranged orthogonally to the first, often qualified as a daughter board, the two boards being provided with rows of ranges of contact arranged in staggered rows, said connector comprising an insulating body in which are formed a corridor for receiving the edge of the second card and passages for crossing flat electrical connection terminals between corresponding contacts of the two cards, each of the terminals having means hooking on the insulating body and a flexible arm intended to slide on the other card during the insertion thereof and to rely on a respective contact pad.

La disposition en quinconce des plages de contact sur les cartes permet d'arriver à un pas de répartition des plages très faible, pouvant descendre jusqu'à 0,25 mm environ. Mais on se heurte alors au problème de la réalisation du corps isolant de réception des contacts. Les cloisons destinées à séparer les bornes de contact et à les maintenir latéralement, ont une épaisseur si faible qu'elles cassent fréquemment et qu'il est même très difficile de réaliser le corps isolant par moulage de matériau plastique renforcée par des charges.The staggered arrangement of the contact pads on the cards makes it possible to arrive at a very small pitch distribution pitch, which can go down to around 0.25 mm. But we then come up against the problem of making the insulating body for receiving the contacts. The partitions intended to separate the contact terminals and to hold them laterally have a thickness so small that they frequently break and that it is even very difficult to produce the insulating body by molding of plastic material reinforced by fillers.

La présente invention vise à fournir un connecteur du type ci-dessus défini, répondant mieux que ceux antérieurement connus aux exigences de la pratique, notamment en ce que son corps isolant est beaucoup plus aisément réalisable, même lorsque le pas de répartition des bornes de contact appartenant à une même rangée est très faible.The present invention aims to provide a connector of the type defined above, meeting better than those previously known the requirements of practice, in particular in that its insulating body is much more easily achievable, even when the pitch of distribution of the contact terminals belonging to the same row is very small.

Dans ce but, l'invention propose un connecteur dans lequel une borne de contact sur deux comporte des moyens d'accrochage encliquetables sur le corps isolant par insertion parallèlement au sens d'engagement de la seconde carte dans le connecteur, tandis que les autres bornes de contact sont encliquetables sur le bloc isolant par déplacement dans le sens orthogonal à la direction d'engagement de la seconde carte.To this end, the invention provides a connector in which one contact terminal out of two comprises latching hooking means on the insulating body by insertion parallel to the direction of engagement of the second card in the connector, while the other terminals of contact can be snapped onto the insulating block by displacement in the direction orthogonal to the direction of engagement of the second card.

En règle générale, chaque borne de contact peut être considérée comme ayant une embase munie des moyens d'accrochage et le bras élastique qui faist saillie vers l'intérieur du connecteur à partir de l'embase et est destiné à glisser sur une face de la seconde carte. L'embase comporte généralement de son côté une saillie destinée à s'appuyer sur une plage de contact respective de la première carte.As a general rule, each contact terminal can be considered as having a base fitted with the hooking means and the elastic arm which projects inwards from the connector from the base and is intended to slide on one face of the second card. The base generally has, for its part, a projection intended to bear on a respective contact pad of the first card.

Grâce à cette disposition des moyens d'accrochage, on peut disposer les passages de traversée des bornes de façon que les passages destinés à une sur deux des bornes (qu'on qualifiera de bornes impaires) ne soient pas alignés avec ceux destinés aux autres bornes (bornes paires). En conséquence, les cloisons séparant les bornes de contact peuvent avoir en majeure partie une épaisseur du même ordre de grandeur que le pas de répartition des bornes de contact, alors que les solutions antérieures conduisaient généralement à donner à ces cloisons une épaisseur sensiblement égale à la différence entre le pas de répartition et l'épaisseur d'une borne.Thanks to this arrangement of the hooking means, it is possible to arrange the terminal crossing passages so that the passages intended for one in two of the terminals (which will be termed odd terminals) are not aligned with those intended for the other terminals. (even terminals). Consequently, the partitions separating the contact terminals may have for the most part a thickness of the same order of magnitude as the pitch of distribution of the contact terminals, whereas the previous solutions generally led to giving these partitions a thickness substantially equal to the difference between the distribution pitch and the thickness of a terminal.

L'invention est susceptible de nombreux modes de réalisation, dont certains seulement seront décrits ci-après.The invention is susceptible of numerous embodiments, only some of which will be described below.

En général les passages de traversée des bornes destinées à s'insérer perpendiculairement à la seconde carte seront constitués par des fentes parallèles ayant une longueur légèrement supérieure à celle du bras de la borne de contact respective, alors que les passages de traversée des bornes insérables parallèlement à la seconde carte seront constituées par des fentes parallèles entre elles ou par des fenêtres pratiquées dans l'isolant et s'ouvrant vers la première carte.In general, the terminal crossing passages intended to be inserted perpendicular to the second card will consist of parallel slots having a length slightly greater than that of the arm of the respective contact terminal, while the terminal crossing passages insertable parallel on the second card will be formed by slots parallel to each other or by windows made in the insulation and opening towards the first card.

L'invention sera mieux comprise à la lecture de la description qui suit de modes particuliers de réalisation, donnés à titre d'exemples non limitatifs.The invention will be better understood on reading the following description of particular embodiments, given by way of nonlimiting examples.

La description se réfère aux dessins qui l'accompagnent, dans lesquels :

  • la figure 1 est une vue simplifiée d'un connecteur selon un mode particulier de réalisation de l'invention, en coupe dans le plan d'une paire de bornes de contact, les éléments indispensables à la compréhension de l'invention étant seuls illustrés ;
  • la figure 2, similaire à la figure 1, est une vue en coupe dans un plan décalé d'un pas de répartition des bornes par rapport au plan de coupe de la figure 1, les éléments situés hors du plan de coupe n'étant pas représentés ;
  • le figure 3 est une vue de détail dans le sens de la flèche f de la figure 1, montrant une répartition possible des bornes de contact.
  • les figures 4 et 5, respectivement similaire aux figures 1 et 2, montrent une variante de réalisation; et la figure est une vue simplifiée, en perspective éclatée, d'un connecteur suivant les figures 4 et 5.
The description refers to the accompanying drawings, in which:
  • Figure 1 is a simplified view of a connector according to a particular embodiment of the invention, in section in the plane of a pair of contact terminals, the elements essential for understanding the invention being alone illustrated;
  • Figure 2, similar to Figure 1, is a sectional view in a plane offset by a distribution pitch of the terminals relative to the section plane of Figure 1, the elements located outside the cutting plane not being represented;

  • Figures 4 and 5, respectively similar to Figures 1 and 2, show an alternative embodiment; and the figure is a simplified view, in exploded perspective, of a connector according to figures 4 and 5.

Le connecteur dont la constitution de principe est montrée en figure 1 comporte un boîtier, dont seul le corps isolant 10 est représenté. Ce corps présente une forme allongée. Il est destiné à être fixé, par des moyens non représentés, sur une première carte 12, ou carte mère, sur laquelle sont disposés deux jeux de plages de contact, chaque jeu ayant des plages 14a et 14b disposées en quinconce. Ce connecteur est destiné à recevoir la tranche d'une seconde carte 16 ou carte fille munie, à proximité de sa tranche, de deux jeux de contact 18a et 18b eux aussi disposés en quinconce. Dans le corps isolant 10 est ménagé un couloir 20 destiné à l'engagement de la carte dans la direction orthogonale à la flèche f.The connector, the basic structure of which is shown in FIG. 1, comprises a housing, of which only the insulating body 10 is shown. This body has an elongated shape. It is intended to be fixed, by means not shown, on a first card 12, or motherboard, on which are arranged two sets of contact pads, each set having pads 14a and 14b arranged in staggered rows. This connector is intended to receive the edge of a second card 16 or daughter card provided, near its edge, with two sets of contact 18a and 18b which are also staggered. In the insulating body 10 is formed a passage 20 intended for the engagement of the card in the direction orthogonal to the arrow f.

Des passages ménagés dans le corps isolant permettent d'y monter des bornes de contact plates 22a et 22b appartenant à deux catégories différentes. Les bornes 18a sont prévues pour être insérées dans le bloc isolant par déplacement transversalement à la direction d'insertion de la seconde carte 16. Les bornes de contact 22b sont prévues pour être insérées dans le corps isolant parallèlement à la direction d'insertion de la seconde carte 16 et dans le sens opposé.Passages made in the insulating body make it possible to mount there flat contact terminals 22a and 22b belonging to two different categories. Terminals 18a are intended to be inserted into the insulating block by displacement transversely to the direction of insertion of the second card 16. The contact terminals 22b are provided to be inserted into the insulating body parallel to the direction of insertion of the second card 16 and in the opposite direction.

L'invention présente surtout un intérêt lorsque le pas de répartition des plages de contact est faible. A l'heure actuelle, on arrive à obtenir un pas de répartion des plages aussi faible que 0,25 mm et pour cela on dispose ces plages en quinconce de façon que la ligne qui relie les centres des plages paires soit écartée de la ligne qui relie les centres des plages impaires d'une distance d d'environ 2mm.The invention is especially of interest when the pitch of distribution of the contact pads is small. At present, it is possible to obtain a pitch distribution pitch as low as 0.25 mm and for this we arrange these ranges in a staggered manner so that the line which connects the centers of the even ranges is separated from the line which connects the centers of the odd ranges with a distance d of about 2mm.

Grâce à une constitution différente des bornes de contact 22a et 22b et à une disposition appropriée des passages de traversée des bornes, il est possible de laisser subsister, entre les bornes, des cloisons de guidage de ces bornes ayant une épaisseur suffisante pour que le corps isolant 10 puisse être moulé sans difficulté.Thanks to a different constitution of the contact terminals 22a and 22b and to an appropriate arrangement of the terminal crossing passages, it is possible to leave, between the terminals, guide partitions of these terminals having a thickness sufficient for the body insulator 10 can be molded without difficulty.

Les bornes 22a et 22b montrées en figures 1 et 2 (qu'on appellera par la suite bornes impaires et paires, mais seulement dans un but de clarté) peuvent l'une et l'autre être considérées comme ayant une embase 24 munie de moyens d'accrochage sur le corps isolant et un bras élastique 26 présentant une partie terminale courbe, destinée à s'appuyer sur une plage de contact 18a ou 18b. Chaque embase présente une saillie ou un renflement inférieur destiné à s'appuyer contre une plage de contact correspondante 14a ou 14b.The terminals 22a and 22b shown in FIGS. 1 and 2 (which will hereinafter be called odd and even terminals, but only for the sake of clarity) can both be considered to have a base 24 provided with means for attachment to the insulating body and an elastic arm 26 having a curved end portion, intended to rest on a contact pad 18a or 18b. Each base has a projection or a lower bulge intended to bear against a corresponding contact pad 14a or 14b.

Dans le mode de réalisation montré en figure 1, les passages de traversée des bornes plates comprennent deux fenêtres 28 s'étendant tout le long du corps isolant 10, sans cloisons intermédiaires entre les bornes, ce qui est sans inconvénient. En effet, les embases, qui doivent être guidées, ne sont pas dans la zone des fenêtres. Les bornes de contact impaires comportent une embase destinée à venir s'appuyer contre des ponts 30 constituant des cloisons de séparation entre les embases des bornes paires 22b. L'embase est munie de deux pattes élastiques 32 terminées chacune par un bec d'accrochage, destinées à encadrer le pont 30 et à s'encliqueter sur lui. On voit que l'ensemble constitué par la partie large de l'embase et les pattes 32 constitue une fourche qui glisse sur le pont 30 lors de l'insertion de la borne de contact et vient s'accrocher sur le pont.In the embodiment shown in FIG. 1, the passages for crossing the flat terminals include two windows 28 extending all along the insulating body 10, without intermediate partitions between the terminals, which is without disadvantage. In fact, the bases, which must be guided, are not in the window area. Terminals odd contact contacts have a base intended to come to bear against bridges 30 constituting partitions between the bases of the even terminals 22b. The base is provided with two elastic tabs 32 each terminated by a hooking spout, intended to frame the bridge 30 and to snap onto it. We see that the assembly constituted by the wide part of the base and the legs 32 constitutes a fork which slides on the bridge 30 during the insertion of the contact terminal and comes to hang on the bridge.

L'embase de chaque borne de contact paire constitue également une fourche ayant un doigt d'accrochage unique 32. Lorsque la borne de contact 24 est mise en place, en la glissant vers le haut sur la figure 2, la fourche vient encadrer un pont 34 et s'encliqueter sur lui. Ce pont constitue une cloison de séparation entre bornes de contact impaires adjacentes 22b et de guidage de ces bornes.The base of each pair contact terminal also constitutes a fork having a single latching finger 32. When the contact terminal 24 is put in place, by sliding it upwards in FIG. 2, the fork comes to frame a bridge 34 and click on him. This bridge constitutes a partition between adjacent odd contact terminals 22b and for guiding these terminals.

On voit, sur la figure 1, que les passages réservés à l'embase de chaque borne impaire correspond sensiblement à l'emplacement de cloisons de guidage des bornes de contact paires et réciproquement. En conséquence, les cloisons peuvent avoir une épaisseur du même ordre de grandeur que le pas de répartition, c'est-à-dire 0,25 mm environ : le moulage de corps isolant dont les cloisons minces ont cette épaisseur ne pose pas de problème particulier.It can be seen, in FIG. 1, that the passages reserved for the base of each odd terminal corresponds substantially to the location of guide partitions for the even contact terminals and vice versa. Consequently, the partitions can have a thickness of the same order of magnitude as the distribution pitch, that is to say approximately 0.25 mm: the molding of insulating body whose thin partitions have this thickness does not pose any problem. particular.

Dans la variante de réalisation montrée en figures 4 et 5 (où les éléments correspondant à ceux des figures 1 à 3 sont désignés par le même numéro de référence), le fond du couloir ménagé dans le corps isolant 10 n'est pas perçé de fenêtres allongées, mais uniquement de fentes destinées aux bornes de contact impaires 22b. Ces fonds sont encore séparés par des cloisons dont l'épaisseur est du même ordre de grandeur que le pas de répartition. L'embase 24 de chaque borne de contact impaire 22b constitue encore une fourche avec la patte d'accrochage 32 munie d'un bec terminal. Ce bec vient s'encliqueter sur un épaulement ménagé dans une nervure centrale 36 s'étendant tout le long du couloir. Chaque borne 22b peut être engagée dans le corps isolant 10 en la poussant vers le haut sur la figure 4.In the alternative embodiment shown in Figures 4 and 5 (where the elements corresponding to those of Figures 1 to 3 are designated by the same reference number), the bottom of the corridor formed in the insulating body 10 is not pierced with windows elongated, but only slots intended for the odd contact terminals 22b. These funds are further separated by partitions whose thickness is of the same order of magnitude as the distribution pitch. The base 24 of each odd contact terminal 22b also constitutes a fork with the hooking lug 32 provided with a terminal spout. This beak snaps onto a shoulder formed in a central rib 36 extending all along the corridor. Each terminal 22b can be engaged in the insulating body 10 by pushing it upwards in FIG. 4.

Les bornes de contact paires 22a comportent elles aussi un bras élastique 26 et une embase 24. L'embase présente une partie large formant une équerre d'appui qui s'appuie sur le fond et sur un flanc du corps isolant 10. La partie verticale de cette embase est guidée par des cloisons de séparation d'avec les bornes paires suivantes. La patte élastique 32 vient s'encliqueter sur la face interne du corps isolant 10 lorsque la borne de contact 22a est insérée en faisant passer le bras de contact 26 à travers la fente correspondante 38 qui constitue un passage de traversée.The paired contact terminals 22a also have an elastic arm 26 and a base 24. The base has a wide part forming a support square which rests on the bottom and on a side of the insulating body 10. The vertical part of this base is guided by partitions with the following even terminals. The elastic tab 32 snaps onto the internal face of the insulating body 10 when the contact terminal 22a is inserted by passing the contact arm 26 through the corresponding slot 38 which constitutes a through passage.

Le boitier du connecteur peut avoir la constitution montrée en figure 6 et comporter le corps isolant 10 et un bloc 40. Le corps 10 représenté est prévu pour être fixé sur la carte 12 (figures 4 et 5) par des vis 42. Le bloc 40 est prévu pour coiffer le corps isolant 10. Une fente (non visible sur la figure 6) y est ménagée pour laisser passer et guider la carte 16.The connector housing can have the constitution shown in FIG. 6 and include the insulating body 10 and a block 40. The body 10 shown is designed to be fixed to the card 12 (FIGS. 4 and 5) by screws 42. The block 40 is provided to cover the insulating body 10. A slot (not visible in FIG. 6) is provided there to allow the card 16 to pass and guide.

L'invention est susceptible de nombreuses autres variantes encore. Elle est applicable aussi bien à des cartes filles 16 à double face du genre montré sur les figures qu'à des cartes simple face. Le corps isolant 10 peut être monté dans l'un quelconque des connecteurs couramment utilisés pour relier une ou plusieurs cartes filles à une carte mère.The invention is susceptible of many other variants as well. It is applicable both to 16 double-sided daughter cards of the kind shown in the figures and to single-sided cards.
