CASE SEALS TO CONTAIN AN ELECTRIC FENCER

Ce boîtier étanche est prévu pour résister à une certaine pression. Il est destiné à contenir un accumulateur électrique notamment. Ce boîtier comporte deux plaques (20 et 21) maintenues entre elles par un cordon (22) plus ou moins élastique. Au niveau d'une partie (23), ce cordon (22) peut glisser entre les plaques de façon à découvrir un orifice (25). On obtient ainsi une valve de sécurité pour des pressions trop importantes. Pour éviter un déplacement démesuré de cette partie de cordon, on a prévu un taquet (30) qui évite ainsi que le cordon déborde des plaques. Application aux accumulateurs.
