The orifices (7) for inserting the plugs may be provided with apropriate isolators. In the case of two plugs, and in order to avoid an erroneous connection, the plugs may have different and incompatible shapes. Application to watches and apparatuses which are battery- operated.

La pile (4) n'est jamais retirée de son logement. Elle se charge par difference de tension maintenue à partir d'une source extérieure. Les deux pôles de la source peuvent être connectés à la montre (1) par l'intermédiaire d'une fiche si le couvercle de la montre est connecté à la masse de son circuit, par l'intermédiaire de deux fiches si le couvercle est isolé, ou par un procédé de connexion sans pénétration. Les orifices (7) d'insertion des fiches peuvent être pourvus d'isolants appropriés. Dans le cas où deux fiches sont utilisées, et afin d'éviter une connexion erronée, les fiches peuvent avoir des formes distinctes et incompatibles. Application aux montres et appareils à pile.
