Abstract

L'invention concerne un adaptateur électrique modulaire intelligent qui comporte une prise mâle rotative qui peut être fixée selon un angle souhaité. Le dispositif offre davantage de flexibilité, ainsi il est plus commode et plus sûr de brancher des appareils électriques. Il est possible d'ajuster et de combiner plusieurs unités de branchement afin de fabriquer un adaptateur comme requis, y compris d'autres types de prises femelles également. Certains connecteurs peuvent comporter des prises femelles rotatives. Les unités (modules) de branchement minces occupent moins de place en hauteur et permettent également d'ajuster les angles, de mettre en œuvre un adaptateur dans un coin et de brancher des modules à la fois horizontalement et verticalement.
