Abstract

La présente invention concerne une prise de courant sans danger qui peut être utilisée en toute sécurité, de telle sorte que les enfants ne soient pas électrocutés même s'ils insèrent des objets tels que des baguettes dans ladite prise. L'invention pourvoit à un nouveau type de dispositif de sécurité qui commande l'arrivée de courant lorsqu'il fonctionne en connexion avec une broche et que ladite broche est introduite dans la prise, et ce dispositif utilise une fiche ayant des spécifications standard, de sorte que le courant arrive uniquement lorsque deux broches de la fiche sont introduites en même temps. Ainsi, cette invention pourvoit à une prise de courant sans danger qui évite les décharges électriques, même si les enfants y introduisent pour s'amuser des tiges métalliques telles que des baguettes. Ce produit est donc sûr et d'une grande fiabilité.
