Abstract

Selon la présente invention, un boîtier (31) comporte une surface. Une bobine (34) est disposée au dos d'une partie de la zone sur la surface. La plage attendue de la partie de la zone est une partie d'une zone (AR) ou toute la zone. La partie de la zone est traitée de telle sorte qu'un joint d'étanchéité métallique ne tende pas à se plier sur cette dernière. L'un quelconque des procédés de traitement suivants peut être utilisé : A. La partie de la zone se présente sous la forme d'une saillie (31a). B. La partie de la zone est rugueuse et n'est pas lisse. C. La partie de la zone est surélevée par rapport à la zone environnante. D. La partie de la zone est en creux par rapport à la zone environnante. Ces procédés de traitement facilitent l'enlèvement d'un joint d'étanchéité métallique et peuvent donc empêcher un chauffage diélectrique.
