Patent

CA 2571222

To make it possible to easily recognize, from an external appearance, whether or not a waterproof tight-sealing level of a coupler penetrating a meter case is adequate. A coupler which is fixed to a meter case (lower case) includes a sleeve which penetrates the case and a flange which overhangs from the sleeve to a circumference thereof. An annular groove holding a seal ring is provided in the flange. A step as a mark is provided on an outer circumference of the sleeve in order that an adequate compression amount of the seal ring can be recognized from the external appearance. This step is aligned with an outer surface of the lower case when the seal ring is compressed up to the adequate compression amount.

Il s'agit de pouvoir facilement reconnaître, à partir de l'aspect extérieur, si le degré d'étanchéité d'un dispositif d'accouplement entrant dans un boîtier de compteur. Un dispositif d'accouplement, fixé à un boîtier de compteur (boîtier inférieur), comprend un manchon qui entre dans le boîtier, et un collet, faisant saillie du manchon jusqu'à sa circonférence. Une gorge circulaire qui maintient une bague d'étanchéité, se trouve dans le collet. Une dent de repérage, en pourtour du manchon, permet de reconnaître, à partir de l'aspect extérieur, si la bague d'étanchéité présente un degré d'étanchéité approprié. Cette dent est alignée avec la surface extérieure du boîtier inférieur lorsque la bague d'étanchéité est comprimée au degré de compression approprié.
