Abstract

L'invention concerne une coque pour un dispositif électronique portable comprenant : une première unité de revêtement de protection conçue pour recouvrir une première partie du bord du dispositif électronique portable, un câble étant intégré à la première unité de revêtement de protection ; une première unité de connexion, installée à une extrémité de la première unité de revêtement de protection, comprenant une première borne de connexion qui est connectée au câble de la première unité de revêtement de protection et peut être connectée à un port de connexion d'un dispositif électronique externe ; et une seconde unité de connexion, installée à l'autre extrémité de la première unité de revêtement de protection, comprenant une seconde borne de connexion qui est connectée au câble de la première unité de revêtement de protection et peut être connectée au port de connexion du dispositif électronique externe. La coque pour dispositif électronique portable permet d'éviter qu'un dispositif électronique portable ne soit endommagé en cas d'impact externe. En outre, la coque pour dispositif électronique portable est pratique étant donné qu'elle assure per se la fonction de câble de connexion, la coque pouvant donc être aisément séparée d'un dispositif électronique portable, si nécessaire, afin de connecter le dispositif électronique portable à un dispositif électronique externe en vue du transfert de données ou du chargement du dispositif électronique portable, sans qu'il soit nécessaire de prévoir un câble de connexion distinct.
