Abstract

Connector having non-sliding contacts, of the type of those which can be electrically connected to conducting tracks 1, 3 printed on parallel surfaces, characterised in that it is constituted by the combination of a rigid insulating board 5 which can be held clamped between the two aforementioned surfaces and by conducting strips 6 fixed to the said board and arranged perpendicularly to the said surfaces and whose ends extend slightly beyond the edge 9 of the board. At least one of the ends of each conducting strip is bent alternately in one direction and then in the other in order to form an elastic half-loop 7 in the form of a V on its side.

Description

La présente invention est relative à un connecteur à contacts non glissants. The present invention relates to a connector with non-sliding contacts.

Le problème posé consiste à relier électriquement des pistes conductrices, imprimées sur une surface, à des pistes identiques imprimées sur une seconde surface devant être disposée parallèlement à la première. The problem is to electrically connect conductive tracks, printed on a surface, to identical tracks printed on a second surface to be arranged parallel to the first.

La première surface précitée peut être l'une des faces d'une cellule à. cristaux liquides tandis que la. seconde est l'une des faces d'une plaque comportant les composants électroniques de commande. The aforementioned first surface can be one of the faces of a cell. liquid crystals while the. second is one of the faces of a plate comprising the electronic control components.

En l'état actuel de la technique, les connexions sont effectuées à l'aide de barrettes, réalisées en une matière élastomère, s'étendant perpendiculairement à l'axe des pistes et constituées chacune par une alternance de parties isolantes et de minces couches conductrices et parallèles affleurant deux chants opposés de ladite barrette. La distance entre deux couches conductrices étant bien inférieure à la largeur d'une piste, le contact électrique entre deux pistes correspondantes s'effectue par l'entremise de plusieurs couches conductrices. In the current state of the art, the connections are made using bars, made of an elastomeric material, extending perpendicular to the axis of the tracks and each constituted by an alternation of insulating parts and thin conductive layers. and parallel flush with two opposite edges of said strip. Since the distance between two conductive layers is much less than the width of a track, the electrical contact between two corresponding tracks takes place through several conductive layers.

De telles barrettes sont particulièrement utilisées dans l'industrie horlogère c'est-à-dire dans un secteur technique dans lequel la température d'utilisation est relativement stable et où la distance séparant les deux séries de pistes est faible (de l'ordre du millimètre J. Such bars are particularly used in the watch industry, that is to say in a technical sector in which the temperature of use is relatively stable and where the distance separating the two series of tracks is small (of the order of millimeter J.

Pour certaines applications telles que l'affichage d'informations au tableau de bord d'un véhicule automobile, il est souhaitable que les composants de la plaque de commande soient disposés entre ladite plaque et la cellule à cristaux liquides; dans ce cas, la distance entre la plaque et la cellule doit être de l'ordre de un à deux centimètres et il en résulte que les barrettes à couches conductrices ne peuvent plus être utilisées. For certain applications such as the display of information on the dashboard of a motor vehicle, it is desirable that the components of the control plate be placed between said plate and the liquid crystal cell; in this case, the distance between the plate and the cell must be of the order of one to two centimeters and it follows that the bars with conductive layers can no longer be used.

En effet, on sait que dans un véhicule automobile, la température du tableau de bord peut varier de façon très importante et que, compte tenu de l'épaisseur de la barrette, les dilatations différentielles sont également importantes. De ce fait, les parties isolantes situées entre deux couches conductrices adjacentes forment un bourrelet et le contact électrique avec la piste n'est plus assuré. Indeed, it is known that in a motor vehicle, the temperature of the dashboard can vary very significantly and that, given the thickness of the bar, the differential expansions are also important. Therefore, the insulating parts located between two adjacent conductive layers form a bead and the electrical contact with the track is no longer ensured.

A cela s'ajoute le fait que la distance entre les couches conductrices étant très faible, de l'ordre du dixième de millimètre, la moindre trace d'humidité suffit pour court-circuiter deux couches adjacentes. Added to this is the fact that the distance between the conductive layers being very small, of the order of a tenth of a millimeter, the slightest trace of humidity is sufficient to short-circuit two adjacent layers.

La présente invention, qui remédie à ces inconvénients, est remarquable en ce que le connecteur comporte une plaquette isolante et rigide dont la hauteur délimite l'écartement des deux surfaces comportant les pistes à relier, le contact électrique entre deux pistes étant assuré par une barrette conductrice maintenue contre ladite plaquette et s'étendant perpendiculairement aux deux surfaces l'une, au moins, des extrémités de ladite barrette étant pliée alternativement dans un sens puis dans l'autre de façon à ce que l'extrémité libre de cette dernière s'étende au-delà du chant correspondant de la plaquette. The present invention, which overcomes these drawbacks, is remarkable in that the connector comprises an insulating and rigid plate, the height of which delimits the spacing of the two surfaces comprising the tracks to be connected, the electrical contact between two tracks being provided by a bar. conductive held against said plate and extending perpendicularly to the two surfaces at least one of the ends of said strip being folded alternately in one direction then in the other so that the free end of the latter s' extends beyond the corresponding edge of the plate.

La présente invention sera mieux comprise par la description qui va suivre, faite en se référant au dessin annexé à titre d'exemple indicatif seulement, sur lequel

Figure 2 is a cross-sectional view of the connector in use;

A of Figure 2;
Figure 4 is a view similar to that 3 showing another embodiment;
FIG. 5 is a sectional view, on a larger scale, taken along the line VV of FIG. 2.

En se reportant au dessin, on voit que le problème consiste à relier électriquement des pistes conductrices 1, imprimées sur une plaque 2,à des pistes conductrices 3 imprimées sur l'une des faces d'une cellule 4 à cristaux liquides qui s'étend parallèlement à ladite plaque 2. La plaque 2, ou plaque de commande, comporte des composants électroniques (non représentés) disposés entre elle et la cellule 4. Referring to the drawing, it can be seen that the problem consists in electrically connecting conductive tracks 1, printed on a plate 2, to conductive tracks 3 printed on one of the faces of a liquid crystal cell 4 which extends parallel to said plate 2. Plate 2, or control plate, includes electronic components (not shown) arranged between it and cell 4.

Selon l'invention, on utilise un connecteur comportant une plaquette 5, rigide et isolante, le long de l'une des faces de laquelle sont maintenues des barrettes conductrices 6 s'étendant perpendiculairement au plan des pistes 1 et 3 et dont les extrémités sont pliées alternativement dans un sens puis dans l'autre de façon à former une demi-boucle 7 en forme de Vé couché, dont I'extrémité 8 libre s'étend légèrement au delà du chant 9 correspondant de ladite plaquette 5; chaque demi-boucle se loge dans une échancrure 10 prévue sur ledit chant de la plaquette. According to the invention, a connector is used comprising a plate 5, rigid and insulating, along one of the faces of which are maintained conductive bars 6 extending perpendicular to the plane of the tracks 1 and 3 and the ends of which are folded alternately in one direction then in the other so as to form a half-loop 7 in the form of a lying Vee, the free end 8 of which extends slightly beyond the corresponding edge 9 of said plate 5; each half-loop is housed in a notch 10 provided on said edge of the wafer.

Comme cela ressort tout particulièrement de la figure 3i l'extrémité 8 est située sensiblement à l'aplomb de la barrette et les deux branches 7a et 7b de la demi-boucle 7 sont sensiblement égales. De cette façon, lorsque la barrette est appliquée en pression contre les pistes, les extrémités 8- se déplacent élastiquement sensiblement selon l'axe lonqitudinal des barrettes conductrices 6. As can be seen very particularly from FIG. 3i, the end 8 is situated substantially at the base of the bar and the two branches 7a and 7b of the half-loop 7 are substantially equal. In this way, when the bar is applied under pressure against the tracks, the ends 8- move elastically substantially along the lonqitudinal axis of the conducting bars 6.

Le mode de réalisation de la partie(a) de la figure 1 et de la figure 2 correspond à l'utilisation d'une plaque de commande comportant des pistes fragiles ne supportant pas de soudure
Le mode de réalisation de la partie (b) de la figure 1 et la figure 4 correspond à l'utilisation d'une plaque de commande dont les pistes peuvent supporter des soudures. Dans ce cas, l'extrémité correspondante des barrettes traverse la plaque par des trous 11 de cette dernière, les pistes 1 étant situées sous la plaque.The embodiment of part (a) of FIG. 1 and of FIG. 2 corresponds to the use of a control plate comprising fragile tracks which do not support welding
The embodiment of part (b) of Figure 1 and Figure 4 corresponds to the use of a control plate, the tracks of which can support welds. In this case, the corresponding end of the bars crosses the plate through holes 11 in the latter, the tracks 1 being located under the plate.

Les barrettes 6 sont maintenues contre la plaquette par tous moyens usuels. Dans le cas de la figure 5, le maintien est effectué par un ramollissement partiel de la matière à l'aide d'ultra-sons qui réalisent des sertissages ponctuels. The bars 6 are held against the wafer by any usual means. In the case of FIG. 5, the maintenance is carried out by a partial softening of the material with the aid of ultra-sounds which produce punctual crimps.

Pour permettre le positionnement de la plaquette 5 par rapport à la plaque 2, celle -ci présente des doigts 12 de centrage pouvant s'engager danses trous 13 de ladite plaque. To allow the positioning of the plate 5 relative to the plate 2, the latter has fingers 12 for centering which can engage in the holes 13 of said plate.

Sur le chant opposé aux doigts 12, la plaquette présente à chaque extrémité une butée 14 limitant le déplacement latéral de la cellule 4 et permettant de positionner les pistes 3 par rapport à celles 1. On the edge opposite the fingers 12, the plate has at each end a stop 14 limiting the lateral displacement of the cell 4 and making it possible to position the tracks 3 relative to those 1.

La plaque 2 et la cellule 4 sont maintenues appliquées contre les chants 9 de la plaquette 5 par tous moyens usuels (non représentés). The plate 2 and the cell 4 are kept applied against the edges 9 of the plate 5 by any usual means (not shown).

Dans l'exemple représenté sur la figure I, la plaque et la cellule présentent deux séries de pistes nécessitant l'utili satin de deux connecteurs, tel que décrits ci-dessus, qui remplissent chacun une double fonction, à savoir:l'entretoisement et les liaisons électriques. In the example shown in FIG. I, the plate and the cell have two series of tracks requiring the use of two satin connectors, as described above, which each fulfill a double function, namely: bracing and electrical connections.

Dans le cas où seule une série de-pistes serait utilisée, on pourrait utiliser une plaquette nue pour maintenir le parallèlisme entre la plaque de commande et la cellule. In the case where only one series of tracks is used, one could use a bare plate to maintain the parallelism between the control plate and the cell.

Bien entendu, la présente invention ne se limite pas au mode de réalisation décrit et représenté mais s'étend, au contraire, à toutes variantes de formes et dimensions.  Of course, the present invention is not limited to the embodiment described and shown but extends, on the contrary, to all variants of shapes and dimensions.
