Abstract

L'objectif de la présente invention est d'empêcher un câble relié à un composant électronique disposé à l'intérieur d'un ballon de sport creux de rompre du fait d'une force extérieure appliquée au ballon de sport et d'éviter tout endommagement des contacts électriques associés avec le câble ou le composant électronique. Le ballon 1 de sport comprend : un corps principal 10 définissant la forme extérieure ; une partie de support de composant électronique 20 disposée à l'intérieur du corps principal 10 et supportant un composant électronique 21 ; des parties de support de borne 30 qui comportent des bornes 31 sur le côté extérieur du corps principal 10 et à partir desquelles des câbles 32 connectant les bornes 31 et le composant électronique 21 s'étendent à l'intérieur du corps principal 10 ; et des parties d'absorption de déplacement 40 disposées à l'intérieur du corps principal 10. Lorsqu'une force extérieure est appliquée sur le corps principal 10 et la position relative de la partie de support de composant électronique 20 est modifiée par rapport aux parties de support de borne 30, les parties d'absorption de déplacement 40 exercent une pression sur la partie de support de composant électronique 20 dans une direction telle que la partie de support de composant électronique 20 retourne à une position relative initiale P qui est la position relative de la partie de support de composant électronique 20 par rapport aux parties de support de borne 30 lorsqu'aucune force extérieure n'est appliquée sur le corps principal 10.
