  • the additional length of the cable harness for connecting the cables when they are not plugged in and inserting them creates additional storage space within the chassis needed, which is disadvantageous, for example, in a motor vehicle because of the limited space available. Another disadvantage arises if the wiring harness also contains optical fibers.

Abstract

L'invention concerne un dispositif selon l'état de la technique, qui permet de maintenir de manière amovible un appareil électrique sur un châssis. L'appareil électrique peut être par exemple un autoradio ou un lecteur de CD et le châssis peut être le tableau de bord d'une automobile. Pour monter l'appareil dans le châssis, il faut extraire de manière générale du châssis un faisceau de câbles avec une surlongueur, auquel l'appareil est connecté. Le faisceau de câbles est ensuite repoussé dans un espace de retenue au niveau du châssis, au moment où l'appareil est inséré dans le châssis. A cet effet, le faisceau de câbles doit présenter une surlongueur. En outre, la position indéfinie du faisceau de câbles dans l'espace de retenue fait que les fibres optiques dudit faisceau de câbles risquent d'être endommagées par un cintrage trop marqué, ce qui peut induire des défaillances lors de la transmission de données. L'invention vise à ne plus rendre la surlongueur du faisceau de câbles nécessaire, à exclure tout risque d'endommagement des fibres optiques situées dans le faisceau de câbles et à éviter l'émergence de défaillances en raison de rayons de courbure trop étroits. A cet effet, il est prévu de monter sur le châssis (17), une unité de contact (1) prévue pour recevoir l'appareil (13), en nutation ou de manière flottante et de munir ladite unité de contact, sur la face extérieure d'une unité de connexion (3) pour les lignes (5) provenant du châssis et sur sa face intérieure, d'une unité enfichable (6) pour une unité enfichable (14) située sur l'appareil (13).
