Each strip is divided into three adjacent plane tabs (3, 5, 7; 4, 6, 8) by two longitudinal slots (15, 17; 16, 18) which are symmetrical in relation to its axis, the end (9, 11, 19; 10, 12, 14) of each tab being shaped in order to ensure that, by snap-fitting the opposite strips in a common plane, each tab of one strip is slightly inflected on one side of this plane and each tab of the other strip on the opposite side, two adjacent tabs of the same strip being inflected on either side of the common plane. <IMAGE>

Description

La présente invention concerne un contact électrique démontable formé par l'accouplement de deux éléments hermaphrodites, lesdits éléments comprenant chacun à une extrémité une lame conductrice élastique de forme générale rectangulaire fendue longitudinalement et à l'autre extrémité un dispositif susceptible d'assurer sa liaison électrique avec un conducteur, chaque lame étant divisée en un nombre impair au moins égal à trois de languettes adjacentes par un nombre pair de fentes longitudinales symétriques par rapport à son axe, l'extrémité de chaque languette étant conformée de manière à assurer que par encliquetage des lames opposées dans un plan commun chaque languette de l'une d'elles se trouve légèrement infléchie d'un côté de ce plan commun, et chaque languette de l'autre du côté opposé de ce plan commun, deux languettes adjacentes d'une même lame étant infléchies de part et d'autre de ce plan commun.The present invention relates to a removable electrical contact formed by the coupling of two hermaphrodite elements, said elements each comprising at one end an elastic conductive strip of generally rectangular shape split longitudinally and at the other end a device capable of ensuring its electrical connection. with a conductor, each strip being divided into an odd number at least equal to three of adjacent tabs by an even number of longitudinal slots symmetrical with respect to its axis, the end of each tab being shaped so as to ensure that by snap-fastening opposite blades in a common plane, each tongue of one of them is slightly bent on one side of this common plane, and each tongue of the other on the opposite side of this common plane, two adjacent tongues of the same blade being inflected on either side of this common plane.

On a déjà proposé dans le document DE-A-3019992 un contact électrique à éléments hermaphrodites, constitués chacun d'une lame de forme générale rectangulaire divisée en deux par une fente longitudi­nale séparant deux languettes, l'une restant dans le plan général de la lame et étant percée d'un trou rectangulaire, l'autre étant décalée d'un côté de ce plan général et comportant un bossage venant s'engager dans le trou de la languette correspondante de l'autre lame.Document DE-A-3019992 has already proposed an electrical contact with hermaphrodite elements, each consisting of a generally rectangular blade divided in two by a longitudinal slot separating two tongues, one remaining in the general plane of the blade and being pierced with a rectangular hole, the other being offset on one side of this general plane and having a boss coming to engage in the hole of the corresponding tongue of the other blade.

Dans un tel système, le contact est réalisé principalement par la jonction des surfaces des languettes en regard, mais il n'existe intrinsèquement aucune force susceptible d'appliquer lesdites surfaces l'une contre l'autre, car chaque élément peut partiellement pivoter autour de l'axe constitué par la fente longitudinale de l'autre élément. En réalité, les languettes ne sont maintenues en contact sur toute leur surface que si les éléments sont montés de façon rigide dans des supports précis qui interdisent tout écart angulaire dans le sens transversal aux éléments.In such a system, the contact is mainly achieved by joining the surfaces of the facing tongues, but there is intrinsically no force capable of applying said surfaces against each other, since each element can partially pivot around the axis formed by the longitudinal slot of the other element. In reality, the tongues are only kept in contact over their entire surface if the elements are rigidly mounted in precise supports which prevent any angular deviation in the direction transverse to the elements.

Le document FR-A-1247715 décrit un contact électrique à éléments hermaphrodites, dont chaque élément comporte une lame élastique divisée longitudinalement en trois languettes par deux fentes parallèles, chaque languette comportant deux cambrures successives de sens opposés et les extrémités de deux languettes adjacentes étant infléchies de part et d'autre du plan moyen de la lame. Il convient dans un tel contact de donner aux cambrages des languettes des valeurs précises avec de faibles tolérances, celles-ci déterminant les forces de contact, qui sont par ailleurs relativement faibles.The document FR-A-1247715 describes an electrical contact with hermaphrodite elements, each element of which comprises an elastic blade divided longitudinally into three tabs by two parallel slots, each tongue comprising two successive bends in opposite directions and the ends of two adjacent tongues being bent on either side of the mean plane of the blade. It is advisable in such a contact to give the bends of the tongues precise values with low tolerances, these determining the contact forces, which are moreover relatively weak.

La présente insertion a pour but de procurer un contact électri­que à éléments hermaphrodites assurant des forces de contact élevées après encliquetage de ses éléments, et par suite de grande fiabilité, et qui ne nécessite pas le respect de valeurs de cambrage déterminées avec de faibles tolérances.The purpose of this insertion is to provide an electrical contact with hermaphrodite elements ensuring high contact forces after snap-fastening of its elements, and consequently of high reliability, and which does not require compliance with bending values determined with low tolerances.

Le contact électrique selon l'invention est caractérisé en ce que chaque languette de ses éléments est de forme générale plane.The electrical contact according to the invention is characterized in that each tab of its elements is of generally planar shape.

Le guidage lors de l'emboîtement mutuel des éléments et leur verrouillage après emboîtement autorisent d'utiliser des supports peu précis auxquels ces éléments sont liés d'une façon lâche et non pas rigide.The guidance during the mutual nesting of the elements and their locking after interlocking allow the use of imprecise supports to which these elements are loosely linked and not rigid.

Le contact de l'invention répond en outre de préférence à au moins l'une des caractéristiques suivantes :
- L'extrémité de chaque languette est légèrement recourbée d'un côté du plan général de la lame, les extrémités de deux languettes adjacentes d'une même lame étant recourbées de part et d'autre de ce plan général.
- L'extrémité de chaque languette comporte un chanfrein orienté vers un côté du plan général de la lame, les chanfrins de deux languettes adjacentes étant orientés l'un vers une face et l'autre vers l'autre face.
- Les bords latéraux de deux languettes adjacentes d'une même lame de part et d'autre d'une fente comportent sur l'une d'elles une lunule et sur l'autre un creux correspondant en regard, les lunules et creux des languettes des lames opposées étant identiques.
- Les fentes de chaque lame font un faible angle aigu avec l'axe longitudinal de celle-ci, de sorte que la largeur de la languette centrale de chaque lame soit plus faible à son extrémité qu'a sa base.
- Les lunules ou les creux de chaque languette sont disposés à mi-longueur de celle-ci.
- Les fentes longitudinales de chaque lame se terminent par un arrondi de faible rayon.The contact of the invention also preferably meets at least one of the following characteristics:
- The end of each tongue is slightly curved on one side of the general plane of the blade, the ends of two adjacent tongues of the same blade being curved on either side of this general plane.
- The end of each tongue has a chamfer oriented towards one side of the general plane of the blade, the chamfers of two adjacent tongues being oriented one towards one face and the other towards the other face.
- The lateral edges of two adjacent tongues of the same blade on either side of a slot have on one of them a lunula and on the other a corresponding hollow opposite, the lunules and hollow of the tongues opposite blades being identical.
- The slots of each blade make a small acute angle with the longitudinal axis thereof, so that the width of the central tongue of each blade is narrower at its end than at its base.
- The lunulae or the hollows of each tab are arranged at mid-length thereof.
- The longitudinal slots of each blade end in a rounded radius.

Il est décrit ci-après, à titre d'exemple et en référence aux figures du dessin annexé, un contact électrique selon l'invention.An electrical contact according to the invention is described below, by way of example and with reference to the figures of the appended drawing.

La figure 1 représente en perspective les deux lames du contact 32 des languettes latérales 6, 8.FIG. 1 represents in perspective the two blades of the contact 32 of the lateral tongues 6, 8.

Les fentes 15, 17 ou 16, 18 des lames se terminent par des arrondis 19, 21 ou 20, 22 de faible rayon qui permettent un découpage net des fentes 15, 17, 16 et 18. Le rapport de la longueur des languettes, mesurée à partir de ces arrondis, à leur largeur est par exemple de 3. Au-delà de ces arrondis, les lames se prolongent par des talons 23, 24 munis chacun d'une liaison électrique avec un conducteur, non représentée.The slots 15, 17 or 16, 18 of the blades end in rounded radii 19, 21 or 20, 22 of small radius which allow a clear cutting of the slots 15, 17, 16 and 18. The ratio of the length of the tongues, measured from these rounded, their width is for example of 3. Beyond these rounded, the blades are extended by heels 23, 24 each provided with an electrical connection with a conductor, not shown.

On voit que si l'on applique les lames l'une contre l'autre face à face dans le même plan, la languette centrale 3 de la lame 1 viendra nécessairement par déformation élastique se glisser au-­dessus de la languette centrale 4 de la lame 2, et les languettes latérales 6 et 8 de la lame 2 au-dessus des languettes latérales 5 et 7 de la lame 1 jusqu'à encliquetage, comme représenté en figure 2, des lunules 25, 29 et 26, 30 dans les creux 28, 32 et 27, 31. On obtient en position encliquetée des contacts face à face entre les languettes 3, 5, 7 et 4, 6, 8 et des contacts latéraux entre les lunules 25, 29 de la languette centrale 3 de la lame 1 et les creux 28, 32 des languettes latérales 6, 8 de la lame 2, d'une part, ainsi qu'entre les lunules 26, 30 de la languette centrale 4 de la lame 2 et les creux 27, 31 des languettes latérales 5, 7 de la lame 1, ce qui assure un contact électrique extrêmement fiable. L'interpénétration des lunules et des creux assure en outre un excellent verrouillage. Bien entendu, les lunules pourraient aussi être disposés sur les languettes latérales, et les creux sur la languette centrale, l'encliquetage ne pouvant évidemment avoir lieu qu'entre lames 1 et 2 identiquement découpées.It can be seen that if the blades are applied one against the other face to face in the same plane, the central tongue 3 of the blade 1 will necessarily come by elastic deformation to slide over the central tongue 4 of the blade 2, and the lateral tabs 6 and 8 of the blade 2 above the lateral tabs 5 and 7 of the blade 1 until snap-fastening, as shown in FIG. 2, of the lunula 25, 29 and 26, 30 in the recesses 28, 32 and 27, 31. In the latched position, one obtains face to face contacts between the tongues 3, 5, 7 and 4, 6, 8 and lateral contacts between the lunules 25, 29 of the central tongue 3 of the blade 1 and the recesses 28, 32 of the lateral tabs 6, 8 of the blade 2, on the one hand, as well as between the lunula 26, 30 of the central tab 4 of the blade 2 and the recesses 27, 31 of the lateral tabs 5, 7 of the blade 1, which ensures an extremely reliable electrical contact. The interpenetration of the lunula and the hollow also ensures excellent locking. Of course, the lunulas could also be arranged on the lateral tabs, and the recesses on the central tab, the snap-fitting can obviously only take place between blades 1 and 2 identically cut.

On peut encore améliorer le verrouillage en donnant aux extré­ mités des languettes centrales une largeur un peu moindre que leur base, les fentes des lames faisant alors un angle de quelques degrés avec leurs axes longitudinaux, ce qui procure un effet de pincement à l'insertion et des forces de contact maximales au verrouillage, comme représenté en figure 3, où la largeur de la languette centrale 3 de la lame 1 à son extrémité 9 est plus faible qu'à sa base, au voisinage des trous 19, 21.We can further improve the locking by giving the extr mites of the central tabs a little less width than their base, the slots of the blades then making an angle of a few degrees with their longitudinal axes, which provides a pinching effect on insertion and maximum contact forces on locking, as shown in FIG. 3, where the width of the central tongue 3 of the blade 1 at its end 9 is narrower than at its base, in the vicinity of the holes 19, 21.

Dans la figure 4, les languettes des lames se terminent par des chanfreins, tels que 39 orienté vers le haut, pour la languette centrale 3 de la lame 1, et 41, orienté vers le bas, pour sa languette latérale 7, ainsi que 42, 44, orientés vers le haut, pour les languet­tes latérales 6, 8 de la lame 2. Ceux-ci assurent nécessairement à l'encliquetage une déflexion élastique vers le haut pour les languettes 3, 6 et 8, et vers le bas pour les languettes telles que 7 (les extrémités de la languette centrale de la lame 2 et de la languette latérale gauche de la lame 1 n'étant pas visibles).In FIG. 4, the tongues of the blades end in chamfers, such as 39 oriented upwards, for the central tongue 3 of the blade 1, and 41, oriented downwards, for its lateral tongue 7, as well as 42 , 44, oriented upwards, for the lateral tabs 6, 8 of the blade 2. These necessarily ensure the snap-fitting elastic deflection upwards for the tabs 3, 6 and 8, and downwards for the tongues such as 7 (the ends of the central tongue of the blade 2 and of the left lateral tongue of the blade 1 not being visible).

Dans le contact tel que décrit, la contrainte de flexion de chaque languette au voisinage des trous 19, 21 et 20, 22 lorsque les lames 1 et 2 sont encliquetées l'une sur l'autre, est déterminée par l'épaisseur des languettes et à un moindre degré en pratique par la longueur des languettes. En fonction du matériau utilisé, il est possible de maintenir cette contrainte inférieure à la limite élastique même avec des lames de forte épaisseur, soit en donnant aux languettes un cambrage permanent inférieur à celui qui résulte de l'encliquetage de deux lames, soit en emboutissant les trois languettes de chaque lame de façon qu'elles ne soient pas strictement coplanaires mais légèrement écartées dans le sens transversal à la lame, la distance entre le plan contenant la languette centrale et le plan contenant les languettes latérales étant inférieure à l'épaisseur de la lame. Les figures 5 et 6 représentent schémati­quement ces deux dispositions.In the contact as described, the bending stress of each tongue in the vicinity of the holes 19, 21 and 20, 22 when the blades 1 and 2 are snapped one on the other, is determined by the thickness of the tongues and to a lesser degree in practice by the length of the tabs. Depending on the material used, it is possible to keep this stress lower than the elastic limit even with very thick blades, either by giving the tongues a permanent arch less than that which results from the snap-fastening of two blades, or by stamping the three tongues of each blade so that they are not strictly coplanar but slightly spaced transversely to the blade, the distance between the plane containing the central tongue and the plane containing the lateral tongues being less than the thickness of the blade. Figures 5 and 6 schematically represent these two arrangements.

Dans la figure 5, la languette centrale 3 fait au repos un angle faible par rapport au plan général de la lame (plan médian du talon 23), au-dessus de celui-ci, tandis que les languettes latérales 5, 7 font avec ce plan général un angle faible, égal et de sens contraire au premier. Ces angles sont de quelques degrés. Les fentes 15, 17 se terminent par des arrondis de faible rayon 19, 21, comme celles représentées en figures 1 et 2. Les languettes pourraient aussi se terminer par des chanfreins de sens opposés comme celles de la figure 4.In FIG. 5, the central tongue 3 makes at rest a small angle relative to the general plane of the blade (median plane of the heel 23), above the latter, while the lateral tongues 5, 7 make with this general plan a small, equal angle and of opposite direction to the first. These angles are a few degrees. The slots 15, 17 end in rounded radii of small radius 19, 21, like those shown in FIGS. 1 and 2. The tongues could also end in chamfers in opposite directions like those in FIG. 4.

Dans la figure 6, la languette centrale 3 est décalée au-­dessus du plan général de la lame (plan médian du talon 23), et les languettes latérales telles que 7 sont décalées au-dessous de ce plan général, le décalage total entre la languette centrale et les languettes latérales restant inférieur à l'épaisseur de la lame (épaisseur du talon ou épaisseur de chaque languette).In FIG. 6, the central tongue 3 is offset above the general plane of the blade (median plane of the heel 23), and the lateral tabs such as 7 are offset below this general plane, the total offset between the central tongue and the lateral tongues remaining less than the thickness of the blade (thickness of the heel or thickness of each tongue).

Dans ces deux variantes, la languette centrale 3 reste munie de lunules 25, 29 et les languettes latérales de creux 37, 31, comme dans les variantes précédentes.In these two variants, the central tongue 3 remains provided with lunules 25, 29 and the lateral hollow tongues 37, 31, as in the preceding variants.
