'invention sera mieux comprise et 'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement dans description explicative qui va suivre faite en référence aux dessins annexés donnés uniquement à titre d'exemple illustrant un mode de réalisation de l'invention et dans lesquels - la figure 1 est une vue en coupe transversale du dispositif d'interconnexion électrique de deux composants conforme à l'invention ; et - la figure 2 est une vue en coupe suivant la ligne II-II de la figure 1. 'invention will be better understood and' other objects, characteristics, details and advantages thereof will appear more clearly in the explanatory description which follows, made with reference to the appended drawings given solely by way of example illustrating an embodiment of the invention and in which - Figure 1 is a cross-sectional view of the electrical interconnection device of two components according to the invention; and - Figure 2 is a sectional view along line II-II of Figure 1.
Les figures 1 et 2 représentent un dispositif d'interconnexion électrique de deux composants constitués respectivement par un câble plat en nappe 1 à plusieurs fils électriques conducteurs 2 noyés dans la nappe 3 en matière plastique souple et une plaque à circuit imprimé 4 sur laquelle sont réalisées un certain nombre de plages conductrices 5 sur lesquelles viennent en contact respectivement les extrémités dénudées 2a des conducteurs électriques 2, les deux composants 1, 4 étant sensiblement en prolongement l'un de l'autre. Figures 1 and 2 show an electrical interconnection device of two components constituted respectively by a flat ribbon cable 1 with several electric conductive wires 2 embedded in the ribbon 3 in flexible plastic material and a printed circuit board 4 on which are made a certain number of conductive pads 5 on which the stripped ends 2a of the electrical conductors 2 respectively come into contact, the two components 1, 4 being substantially in extension of one another.
Selon l'invention, le dispositif comprend deux demi-coquilles 6, 7 en un matériau électriquement isolant tel que par exemple une matière plastique, et assemblees l'une sur l'autre en enserrant entre elles une partie d'extrémité 4a de la plaque à circuit imprimé 4 et une partie d'extrémité la du câble plat en nappe 1 comportant les extrémités dénudées 2a de façon à mettre en contact par pression élastique ces extrémités respectivement sur les plages conductrices 5. According to the invention, the device comprises two half-shells 6, 7 made of an electrically insulating material such as for example a plastic material, and assembled one on the other by enclosing between them an end portion 4a of the plate with printed circuit 4 and an end part 1a of the flat ribbon cable 1 comprising the stripped ends 2a so as to bring these ends into contact by elastic pressure respectively on the conductive pads 5.
Plus précisément, les deux demi-coquilles 6, 7 sont chacune conformées en coin et logées dans une pièce en étrier de forme conjuguée de façon que les branches 8a de la pièce 8 soient en appui respectivement sur les deux faces iques 6a, 7a des deux demi-coquilles 6, 7 pour exercer un effort de rapprochement et de maintien par cerclage des deux demi-coquilles 6, 7. Cet effort est suffisant pour qu'une feuille en élastomère logée dans une cavité de forme conjuguée 6b réalisée dans la demi- coquille 6 soit comprimée élastiquement en appui sur les extrémités dénudées 2a des conducteurs 2 pour maintenir celles-ci en contact sur les plages conductrices 5. More specifically, the two half-shells 6, 7 are each shaped as a wedge and housed in a stirrup piece of conjugate shape so that the branches 8a of the piece 8 are in contact respectively on the two ic faces 6a, 7a of the two half-shells 6, 7 to exert an effort of bringing together and holding by strapping of the two half-shells 6, 7. This effort is sufficient for a sheet of elastomer housed in a conjugate cavity 6b produced in the half shell 6 is compressed elastically by pressing on the stripped ends 2a of the conductors 2 to keep these in contact on the conductive pads 5.
La partie d'extrémité 4a de la plaque 4 est logée dans une feuillure 7b de la demi-coquille située en dessous du plan de joint des deux demi-coquilles 6, 7 contenant la ligne de coupe II-II et perpendiculaire au plan de la figure 1 et la partie d'extrémité du câble plat en nappe 1 est située sensiblement dans ce plan de joint en prolongement décalé de la plaque 4. The end part 4a of the plate 4 is housed in a rebate 7b of the half-shell located below the joint plane of the two half-shells 6, 7 containing the section line II-II and perpendicular to the plane of the FIG. 1 and the end part of the flat ribbon cable 1 is situated substantially in this joint plane in offset offset from the plate 4.
Les deux demi-coquilles 6, 7 comprennent en outre deux parties dentelées 6c, 7c situées en regard l'une de l'autre pour retenir la partie d'extrémité du câble entre les deux demi-coquilles 6, 7, cette partie d'extrémité traversant une fenêtre de passage 8b realisée dans la paroi de liaison 8c des deux branches 8a. The two half-shells 6, 7 further comprise two serrated parts 6c, 7c located opposite one another to retain the end portion of the cable between the two half-shells 6, 7, this part of end passing through a passage window 8b produced in the connecting wall 8c of the two branches 8a.
feuille en élastomère 9 presse non seulement les extrémités dénudées des fils conducteurs 2 sur leurs plages conductrices respectives 5, mais presse également la matiere plastique isolante du câble 1 notamment sur la partie dentelée 7c. elastomer sheet 9 not only presses the stripped ends of the conductive wires 2 onto their respective conductive pads 5, but also presses the insulating plastic material of the cable 1 in particular on the serrated part 7c.
Afin d'éviter un écrasement de la partie la du câble 1 entre les deux demi-coquilles 6, 7, la demi- coquille supérieure 6 comprend une paroi frontale 6d transversale à la plaque à circuit imprimé 4 et appui sur cette dernière. La paroi 6d empêche également le retrait de la plaque 4 des deux demi-coquilles réunies 6, 7 en position d'assemblage par la pièce en étrierIn order to avoid crushing of the part 1a of the cable 1 between the two half-shells 6, 7, the upper half-shell 6 comprises a front wall 6d transverse to the printed circuit board 4 and pressing on the latter. The wall 6d also prevents the withdrawal of the plate 4 from the two joined half-shells 6, 7 in the assembly position by the part in the stirrup
