Abstract

La présente invention concerne un concentrateur USB, comprenant un boîtier et une carte de circuit imprimé fixée à l'intérieur du boîtier, la carte de circuit imprimé étant pourvue d'au moins deux interfaces USB. Le boîtier comprend une coque avant et une coque arrière, lesdites coques étant fixées de manière amovible. Du fait que le boîtier du présent concentrateur USB comprend les deux coques avant et arrière fixées de manière amovible, si une défaillance se produit dans le concentrateur USB, les coques avant et arrière peuvent être désaccouplées, ce qui permet une inspection et une réparation. Le présent concentrateur USB est par conséquent pratique à utiliser.
