Patent

CA 2272571

The invention relates to a housing which receives dry cells in an in-line or end to end orientation. The invention includes features which prevent the incorrect orientation by preventing dry cell terminals making contact with the necessary components. In this way it prevents premature dissipation of dry cells or their impairment. The mechanism by which these features do this is to recess one terminal namely that terminal which would be contacted by the positive terminal of a dry cell. In this way the negative terminal of a dry cell can never make electrical connection. Another feature of the invention is the provision of an aperture having a profile of a silhouette of a dry cell, which has advantages in low light situations, saves material, and allows for relatively easy extraction of dry cells from the cartridge.

L'invention porte sur un réceptacle recevant des piles sèches placées en ligne ou bout-à-bout. L'invention présente des caractéristiques empêchant l'orientation incorrecte en empêchant les bornes des piles d'entrer en contact avec les composants nécessaires. On évite ainsi la dissipation des piles ou leur dégradation. Le procédé permettant d'arriver à ce résultat consiste à mettre une borne en retrait, cette borne étant celle qui doit être en contact avec la borne positive d'une pile sèche. Ainsi, la borne négative d'une pile sèche ne peut jamais être en contact électrique. Un autre aspect de l'invention consiste à prévoir une ouverture présentant le profil de la silhouette d'une pile, ce qui présente des avantages en cas de lumière faible, économise les matériaux et permet une extraction relativement facile des piles de la cartouche.
