Les lyres utilisées actuellement donnent généralement satisfaction, par exemple celle représentée en figure 1 et dont la découpe (d) reçoit une languette (non représentée) insérée dans le sens The lyres currently used are generally satisfactory, for example that shown in FIG. 1 and the cutout (d) of which receives a tongue (not shown) inserted in the direction
de la flèche (f), et maintenue par élasticité entre deux têtes (t). of the arrow (f), and held by elasticity between two heads (t).
Cependant la demanderesse s'est fixée pour but d'en améliorer However, the applicant has set itself the goal of improving it
encore les performances et de simplifier leur industrialisation. further performance and to simplify their industrialization.
Ce but est atteint par un élément de contact électrique qui se caractérise en ce qu'il comporte au moins une lyre à deux branches comportant dans leur partie haute deux bossages tournés vers une découpe centrale d'insertion et positionnés de telle sorte que deux sommets de l'une des branches soient décalés par rapport aux sommets de l'autre branche. This object is achieved by an electrical contact element which is characterized in that it comprises at least one lyre with two branches comprising in their upper part two bosses facing a central insertion cutout and positioned so that two vertices of one of the branches are offset from the vertices of the other branch.
On comprendra mieux l'invention à l'aide de la description The invention will be better understood using the description

l'invention dans un boîtier connecteur. the invention in a connector housing.
Une lyre (1) selon l'invention présente une découpe d'insertion (7) de forme particulière non symétrique par rapport à l'axe A lyre (1) according to the invention has an insertion cutout (7) of a particular shape that is not symmetrical with respect to the axis
longitudinal de la lyre.longitudinal of the lyre.
La découpe d'insertion (7) présente: - une partie basse (6) proche de la forme en V habituelle et permettant l'écartement et le retour élastique des deux branches (8), - une partie haute comportant deux bossages sur chacune des deux branches (8). Les bossages sont positionnés de telle sorte que le sommet (5a) du premier bossage de l'une des branches est centré par rapport aux deux sommets (5b) et (5c) des bossages de l'autre branche, et le sommet (5d) du deuxième bossage de la première branche est légèrement The insertion cutout (7) has: - a lower part (6) close to the usual V shape and allowing the spacing and elastic return of the two branches (8), - an upper part comprising two bosses on each of the two branches (8). The bosses are positioned so that the apex (5a) of the first boss of one of the branches is centered with respect to the two vertices (5b) and (5c) of the bosses of the other branch, and the apex (5d) of the second boss of the first branch is slightly
décalé ou non par rapport au sommet (5b) de l'autre branche. offset or not relative to the top (5b) of the other branch.
En outre les bossages (5b) et (5d) des extrémités des deux branches se terminent par deux formes de courbure particulière (4) permettant une entrée symétrique et le bossage de sommet (5d) associé au bossage (5b) de l'autre branche permet une ouverture partielle à In addition, the bosses (5b) and (5d) of the ends of the two branches end in two particular forms of curvature (4) allowing a symmetrical entry and the crown boss (5d) associated with the boss (5b) of the other branch. allows partial opening at
l'introduction de la languette (2).the introduction of the tongue (2).
La lyre selon l'invention est obtenue uniquement par détourage ce qui simplifie la fabrication et la forme particulière de la découpe (7), permet la réalisation d'un poinçon de découpe selon les techniques connues. I1 découle de ces deux particularités une régularité géométrique nettement améliorée, une utilisation optimisée des The lyre according to the invention is obtained only by trimming which simplifies the manufacture and the particular shape of the cutout (7), allows the production of a cutter punch according to known techniques. I1 follows from these two features a significantly improved geometric regularity, an optimized use of
caractéristiques élastiques du matériau, une régularité du serrage. elastic characteristics of the material, regularity of the tightening.
3 - Lors de l'insertion d'une languette (2) (figure 6), la lyre (1) exerce une action élastique symétrique associée à la forme d'entrée 3 - When inserting a tongue (2) (Figure 6), the lyre (1) exerts a symmetrical elastic action associated with the entry form
particulière (4) ce qui permet le recentrage de la languette (2). particular (4) which allows the refocusing of the tongue (2).
La forme particulière à quatre bossages (5) permet une progressivité de l'effort d'insertion par ouverture partielle de la lyre produite par appui de la languette sur les sommets (5b) et (5d), lorsque l'insertion est totale, trois des sommets sont en contact avec la languette (2) (voir figure 4) en raison de l'écartement des deux branches (8). Cependant dans l'état de la technique représenté en figure 1, il n'existe que deux points ou surfaces de contacts entre une languette The particular shape with four bosses (5) allows a progressive insertion effort by partial opening of the lyre produced by pressing the tongue on the vertices (5b) and (5d), when the insertion is complete, three vertices are in contact with the tongue (2) (see Figure 4) due to the spacing of the two branches (8). However in the state of the art represented in FIG. 1, there are only two points or surfaces of contact between a tongue
insérée et les deux têtes (t).inserted and the two heads (t).
Donc par rapport à l'état de la technique, le nombre des surfaces de contact est augmenté de 50 %, d'o une amélioration du contact électrique, une réduction de l'échauffement, une réduction des pressions de contact entre lyre et languette réduisant les risques de So compared to the state of the art, the number of contact surfaces is increased by 50%, hence an improvement in electrical contact, a reduction in heating, a reduction in contact pressures between lyre and reducing tongue the risks of
grippage ou de soudure.seizing or welding.
De façon préférentielle, et grâce à l'implantation particulière de la découpe selon l'invention on peut insérer la languette de telle sorte que la lyre (1) soit décentrée et décalée d'une valeur (x) par rapport à l'axe de symétrie (9) de la languette (voir figure 5) sur Preferably, and thanks to the particular location of the cutout according to the invention, the tongue can be inserted so that the lyre (1) is off-center and offset by a value (x) relative to the axis of symmetry (9) of the tongue (see figure 5) on
lequel est situé généralement un trou (3) de verrouillage. which is generally located a locking hole (3).
Ce décentrage permet l'utilisation similaire de languettes This off-center allows the similar use of tabs
équipées ou non de trous (3).with or without holes (3).
Selon la puissance à transmettre, il est connu de jumeler des lyres. La lyre selon l'invention se prête particulièrement bien à la fabrication de lyres jumelées (voir figure 7) puisqu'on peut les réaliser en seulement deux opérations: détourage puis pliage du flan, tout en Depending on the power to be transmitted, it is known to pair lyres. The moving head according to the invention lends itself particularly well to the manufacture of twin moving heads (see FIG. 7) since they can be produced in only two operations: trimming then folding the blank, while
conservant la possibilité des liaisons habituelles. retaining the possibility of the usual connections.
De façon préférentielle, la lyre selon l'invention est associée à un montage en trois dimensions dans des boitiers connecteurs (11) (voir figure 8) qui se caractérise par le fait que tous ses éléments (12) sont verticaux et par l'absence de plan d'interconnexion horizontal - 4 - d'o simplification de la plièce plastique (10) du boitier, les efforts Preferably, the lyre according to the invention is associated with a three-dimensional mounting in connector boxes (11) (see FIG. 8) which is characterized by the fact that all of its elements (12) are vertical and by the absence horizontal interconnection plan - 4 - o simplification of the plastic part (10) of the case, the forces
étant transmis directement.being transmitted directly.
En outre, elle permet une forte économie de matière par son In addition, it allows a strong saving of material by its
absence d'opérations intermédiaires de solidarisation. absence of intermediate solidarity operations.
