Description

Dispositif électronique comportant un connecteur élastomère feuilleté, et procédé d'assemblage. Electronic device comprising a laminated elastomeric connector, and method of assembly.
L'invention concerne un dispositif électronique comportant un connecteur élastomère feuilleté, ainsi qu'un procédé d'assemblage.The invention relates to an electronic device comprising a laminated elastomeric connector and an assembly method.
ARRIERE-PLAN DE L' INVENTIONBACKGROUND OF THE INVENTION
On connaît des dispositifs électroniques comportant un connecteur élastomère feuilleté (également appelé connecteur « zébra ») comportant une succession de couches élastomères conductrices et de couches élastomères non-conductrices, le connecteur s 'étendant entre un premier élément porteur de pistes conductrices, par exemple une carte à circuit imprimé, et un second élément porteur de pistes conductrices, par exemple un écran à cristaux liquides, pour relier électriquement les pistes conduc- trice du premier élément avec les pistes conductrices du second élément .Electronic devices are known comprising a laminated elastomeric connector (also called "zebra" connector) comprising a succession of conductive elastomeric layers and non-conductive elastomeric layers, the connector extending between a first element carrying conductive tracks, for example a printed circuit board, and a second carrier element of conductive tracks, for example a liquid crystal screen, for electrically connecting the conductive tracks of the first element with the conductive tracks of the second element.
En général, le connecteur s'étend dans un logement traversant d'un guide de lumière qui s'étend entre la carte à circuit imprimé et l'écran à cristaux liquides et qui forme un organe d' entretoisèment ayant une hauteur inférieure à une hauteur du connecteur élastomère feuilleté.In general, the connector extends into a housing passing through a light guide that extends between the printed circuit board and the liquid crystal display and forms a brace member having a height less than a height. of the laminated elastomeric connector.
Lors du montage, on empile la carte à circuit imprimé, le guide de lumière dans le logement duquel le connecteur est introduit, l'écran à cristaux liquides, et enfin une bride servant à compresser le connecteur jusqu'à ce que la carte à circuit imprimé et l'écran à cristaux liquides soient en appui contre le guide de lumière. Avant serrage, le guide de lumière est maintenu sous l'effet de la gravité contre la carte à circuit im¬ primé, de sorte que la partie du connecteur qui s'étend du côté de l'écran est en saillie du guide de lumière. Ainsi, pendant toute la durée du serrage, et notamment dans la phase finale lorsque les efforts de serrage sont importants, l'écran est en appui uniquement sur le con- necteur, ce qui induit dans l'écran des contraintes pouvant entraîner sa rupture .During assembly, the circuit board is stacked, the light guide in the housing of which the connector is inserted, the LCD screen, and finally a flange for compressing the connector until the circuit board printed and the LCD screen rest against the light guide. Before clamping, the light guide is maintained under the effect of gravity against the circuit board im ¬ award, so that the portion of the connector which extends from the side of the screen is projecting from the light guide. Thus, during the entire duration of the clamping, and in particular in the final phase when the clamping forces are important, the screen bears only on the nector, which induces in the screen constraints that could lead to its break.
OBJET DE L'INVENTIONOBJECT OF THE INVENTION
L'invention a pour objet un dispositif électroni- que pourvu de moyens pour diminuer le risque d' endommagement de l ' écran.The invention relates to an electronic device provided with means for reducing the risk of damaging the screen.
BREVE DESCRIPTION DE L'INVENTIONBRIEF DESCRIPTION OF THE INVENTION
En vue de la réalisation de ce but, on propose un dispositif électronique comportant un connecteur élas- tomère feuilleté s 'étendant entre un premier élément porteur de pistes conductrices et un second élément porteur de pistes conductrices pour relier électriquement les pistes conductrices du premier élément avec les pistes conductrices du second élément, le connecteur s 'étendant dans un logement traversant d'un organe d' entretoisement disposé entre les éléments et ayant une hauteur inférieure à une hauteur du connecteur élastomère feuilleté, le dispositif comportant selon l'invention un organe dé- formable s 'étendant entre le premier élément et l'organe d' entretoisement pour les maintenir écartés avant un serrage tendant à mettre en appui les éléments contre l'organe d' entretoisement .With a view to achieving this object, an electronic device is provided comprising a laminated elastomeric connector extending between a first conductive track carrying member and a second conducting lead carrying member for electrically connecting the conductive tracks of the first member with the conductive tracks of the second element, the connector extending in a housing through a spacer member disposed between the elements and having a height less than a height of the laminated elastomeric connector, the device comprising according to the invention a body of - formable extending between the first member and the spacer member to keep them apart before tightening tending to support the elements against the spacer member.
Ainsi, la partie du connecteur saillant de l'organe d' entretoisement a une hauteur réduite, ce qui diminue la phase du serrage pendant laquelle le second élément est en appui uniquement sur le connecteur. Le serrage se termine par une phase pendant laquelle l'organe d1 entretoisement est en appui contre le second élément, ce qui contribue à répartir les contraintes d'appui dans le second élément, et diminue ainsi les risques de rupture de ce dernier.Thus, the portion of the protruding connector of the spacer member has a reduced height, which decreases the clamping phase during which the second element bears only on the connector. The clamping ends with a phase during which the organ spacer 1 is supported against the second component, which helps to distribute the stresses of support in the second element, and so reduces the risk of rupture of the latter.
Selon un mode de réalisation particulier de l'invention, l'organe déformable est agencé pour maintenir entre le premier élément et l'organe d' entretoisement un écart égal ou supérieur à une différence entre la hau- teur du connecteur et la hauteur de l'organe d' entretoisement .According to a particular embodiment of the invention, the deformable member is arranged to maintain between the first element and the spacer member a difference equal to or greater than a difference between the height connector and the height of the bracing member.
Ainsi, le second élément est en appui contre la face d'appui de l'organe d' entretoisement sous l'action de l'organe élastique pendant toute la durée du serrage. L'organe d1 entretoisement forme une bordure qui empêche le connecteur de déborder lors du serrage entre l'organe d1 entretoisement et le second élément.Thus, the second element is in abutment against the bearing face of the spacer member under the action of the elastic member during the entire duration of the clamping. The spacing d 1 forms a border member which prevents the connector from overflowing during the tightening member between the spacer d 1 and the second member.
L'invention a également pour objet un procédé d'assemblage d'un dispositif électronique comportant un connecteur élastomère feuilleté s 'étendant entre un premier élément porteur de pistes conductrices et un second élément porteur de pistes conductrices pour relier électriquement les pistes conductrices du premier élément avec les pistes conductrices du second élément, le connecteur s 'étendant dans un logement traversant d'un organe d' entretoisement disposé entre les éléments et ayant une hauteur inférieure à une hauteur du connecteur élastomère feuilleté, le procédé comportant l'étape de main- tenir écarté l'organe d' entretoisement du premier élément avant un serrage tendant à mettre en appui les éléments contre l'organe d' entretoisement .The subject of the invention is also a method of assembling an electronic device comprising a laminated elastomeric connector extending between a first element carrying conductive tracks and a second element carrying conducting tracks for electrically connecting the conductive tracks of the first element. with the conductive tracks of the second element, the connector extending in a through-housing of a spacer member disposed between the elements and having a height less than a height of the laminated elastomeric connector, the method comprising the step of maintaining keep the spacer member away from the first element before tightening tending to press the elements against the spacer member.

DESCRIPTION DETAILLEE DE L'INVENTION En référence aux figures, le dispositif électro- nique de l'invention comporte un connecteur élastomère feuilleté 1 qui s'étend entre une carte à circuit imprimé 2 et un écran à cristaux liquides 3 pour relier électriquement des pistes conductrices de la carte à circuit im- primé 2 à des pistes conductrices en regard de l'écran à cristaux liquides 3. La carte à circuit imprimé 1 porte des composants électroniques (non représentés) de commande de l'écran à cristaux liquides 3.DETAILED DESCRIPTION OF THE INVENTION Referring to the figures, the electronic device The invention comprises a laminated elastomeric connector 1 which extends between a printed circuit board 2 and a liquid crystal screen 3 for electrically connecting conductive tracks of the printed circuit board 2 to conductive tracks facing each other. of the LCD 3. The printed circuit board 1 carries electronic components (not shown) for controlling the LCD screen 3.
Le connecteur 1 s'étend dans un logement 4 tra- versant creusé dans le bord 6 d'un guide de lumière 5 disposé entre la carte à circuit imprimé 2 et l'écran à cristaux liquides 3. De façon connue en soi, le guide de lumière 5 comporte une partie oblique qui s'étend en regard de l'écran à cristaux liquides 3 pour conduire de la lumière produite par des diodes (non représentées) portées par la carte à circuit imprimé 2 et réfléchir cette lumière vers l'écran à cristaux liquides 3.The connector 1 extends into a through-hole 4 in the edge 6 of a light guide 5 disposed between the printed circuit board 2 and the liquid crystal screen 3. In a manner known per se, the guide 5 comprises an oblique portion which extends opposite the liquid crystal screen 3 to conduct light produced by diodes (not shown) carried by the printed circuit board 2 and reflect this light to the screen liquid crystal 3.
Il est connu de comprimer le connecteur 1 afin d'assurer un bon contact entre le connecteur 1 et les pistes conductrices. A cet effet, le connecteur 1 a une hauteur H qui est supérieure à la hauteur L du bord 6, et le dispositif comporte une bride 7 qui coiffe l'écran à cristaux liquides au droit du connecteur et qui reçoit deux vis 8 dont les têtes prennent appui sur la carte à circuit imprimé 2.It is known to compress the connector 1 to ensure good contact between the connector 1 and the conductive tracks. For this purpose, the connector 1 has a height H which is greater than the height L of the edge 6, and the device comprises a flange 7 which cap the liquid crystal screen to the right of the connector and which receives two screws 8 whose heads rely on the printed circuit board 2.
Le serrage des vis 8 provoque la compression du connecteur jusqu'à ce que la carte à circuit imprimé 2 et l'écran à cristaux liquides 3 viennent en contact avec le bord 6 du guide de lumière 5. Le bord 6 forme ainsi une entretoise entre la carte à circuit imprimé 2 et l'écran à cristaux liquides 3.The tightening of the screws 8 causes the compression of the connector until the printed circuit board 2 and the liquid crystal screen 3 come into contact with the edge 6 of the light guide 5. The edge 6 thus forms a spacer between the printed circuit board 2 and the LCD screen 3.
Selon l'invention, le bord 6 comporte des languettes flexibles 10 moulées avec le guide de lumière 5 et qui s'étendent parallèlement à la carte à circuit im- primé 2. Des plots 11 sont fixés aux extrémités des lan- guettes flexibles 10.According to the invention, the edge 6 comprises flexible tongues 10 molded with the light guide 5 and which extend parallel to the printed circuit board 2. The studs 11 are fixed at the ends of the lanterns. flexible lugs 10.
Les plots 11 sont en appui contre la carte à circuit imprimé 2 et maintiennent le bord 6 écarté de la carte à circuit imprimé 2 d'un écart E égal à la diffé- rence entre la hauteur H du connecteur et la hauteur L du bord 6. Ainsi, la face 12 du bord 6 destinée à prendre appui contre l'écran à cristaux liquides 3 et la face 13 du connecteur 1 en regard de l'écran à cristaux liquides 3 sont sensiblement alignées. Pendant toute la durée du serrage des vis 8, la face 12 du bord 6 reste constamment en appui contre l'écran à cristaux liquides 3 sous l'effet de la poussée générée par la flexion des languettes 10.The studs 11 bear against the printed circuit board 2 and keep the edge 6 spaced apart from the printed circuit board 2 by a distance E equal to the difference between the height H of the connector and the height L of the edge 6 Thus, the face 12 of the edge 6 intended to bear against the liquid crystal screen 3 and the face 13 of the connector 1 opposite the liquid crystal screen 3 are substantially aligned. During the entire duration of the tightening of the screws 8, the face 12 of the edge 6 remains constantly resting against the liquid crystal screen 3 under the effect of the thrust generated by the flexion of the tongues 10.
L'appui de l'écran à cristaux liquides 3 est ain- si réparti à la fois sur le connecteur 1 et sur le bord 6, adoucissant la discontinuité des contraintes d'appui qui prend naissance sur l'écran au niveau du rebord du connecteur 1.The support of the liquid crystal screen 3 is distributed equally over both the connector 1 and the edge 6, softening the discontinuity of the support stresses which originates on the screen at the edge of the connector 1.
Cette répartition diminue sensiblement le risque de rupture de l'écran à cristaux liquides 3 lors du serrage.This distribution substantially reduces the risk of rupture of the LCD screen 3 during tightening.
L'invention n'est pas limitée à ce qui vient d'être décrit, mais bien au contraire englobe toute variante entrant dans le cadre défini par les revendica- tions.The invention is not limited to what has just been described, but on the contrary encompasses any variant within the scope defined by the claims.
En particulier, bien que l'on ait illustré l'organe d' entretoisement sous la forme d'un bord d'un guide de lumière disposé entre une carte à circuit imprimé et un écran à cristaux liquides, l'organe d' entretoisement pourra plus généralement être formé de toute pièce pourvue d'un logement traversant pour recevoir le connecteur et qui s'étend entre deux éléments porteurs de pistes conductrices.In particular, although the bracing member has been illustrated in the form of an edge of a light guide disposed between a printed circuit board and a liquid crystal display, the bracing member may more generally be formed of any part provided with a through housing for receiving the connector and which extends between two conductor carrier elements.
Bien que l'organe déformable illustré ici com- prend des languettes flexibles en une pièce avec l'organe d'entretoisement et des plots d'appui, l'organe déforma- ble pourra plus prendre tout autre configuration du moment qu'il permette de maintenir un écart entre un premier élément et l'organe d'entretoisement avant serrage. L'organe déformable peut également être solidaire du premier élément, ou encore n'être solidaire ni du premier élément ni du second élément. Dans ce cas, il pourra être enlevé après serrage .Although the deformable member illustrated here comprises flexible tabs in one piece with the member bracing and support pads, the deformable member can take any other configuration as long as it allows to maintain a gap between a first element and the spacer member before tightening. The deformable member may also be integral with the first element, or may not be secured to either the first element or the second element. In this case, it can be removed after tightening.
Bien que l'on ait indiqué ici que l'écart mainte- nu par l'organe déformable est égal à la différence entre la hauteur du connecteur et la hauteur de l'organe d'entretoisement, de sorte que la surface de l'organe d'entretoisement et la surface du connecteur en regard du second élément soient sensiblement alignées, l'écart pourra être supérieur à cette différence, bien que l'on augmente alors le risque de pincer le connecteur entre l'organe d'entretoisement et le premier élément. L'écart pourra être également inférieur à cette différence. Dans cette configuration, le second élément est en appui sur le connecteur seul uniquement au début du serrage, le second élément venant en appui sur l'organe d'entretoisement en cours de serrage, et notamment dans la phase finale de celui-ci. Although it has been stated here that the gap maintained by the deformable member is equal to the difference between the height of the connector and the height of the spacer member, so that the surface of the member spacing and the surface of the connector facing the second element are substantially aligned, the difference may be greater than this difference, although it increases the risk of pinching the connector between the spacer member and the first element. The difference may also be smaller than this difference. In this configuration, the second element is supported on the connector only at the beginning of the clamping, the second element bearing on the spacer member during tightening, and in particular in the final phase thereof.
