Abstract

L'invention concerne des câbles d'alimentation électrique rétractables, comprenant des supports (1), une couverture (2) et au moins deux conducteurs (3) ; les supports (1) sont constitués de nervures pliées sur la direction en longueur des câbles ; la couverture (2) est constituée de pièces en plastique mou de type feuille en utilisant les supports comme cadre et en pliant dans la même direction ; une cavité de réception (23) accueillant les au moins deux conducteurs (3) à l'intérieur de celle-ci est ménagée au milieu de la coupe transversale des pièces en plastique mou de type feuille ; une ailette gauche (21) et une ailette droite (22) s'étendent respectivement à partir des deux côtés de la coupe transversale ; avec la couverture (2) pliée, les bords d'une ailette gauche (21) et d'une ailette droite (22) voisines se scellent l'une à l'autre ; et lorsque les câbles sont dans un état rétracté, l'ailette gauche (21) et l'ailette droite (22) voisines sont pliées conjointement pour former une paroi pliée en spirale interne à l'intérieur du cadre de support. Les câbles sont non seulement rétractables facilement et librement comme les câbles rétractables existants, mais en outre ne sont pas sujets à une usure et à un déchirement et sont faciles à nettoyer, car la couverture est uniformément disposée entre les pièces du cadre de support en spiral, et pliée à l'intérieur du cadre de support ; de plus, les câbles rétractables sont munis d'une protection à double couche efficace, assurant une alimentation électrique plus sûre et plus fiable.
