A fastener (12) assembly for joining a first element (13) such as a circuit board to a second element such as a casing includes a first component (19) which has a pin (20) and a second component (24) which includes a cavity (28) for receiving at least part of the pin (20). Either the first component or the second component is made of a material adapted to change from a first shape to second shape at a particular temperature. The pin (19) of the first component is adapted to be locked into the cavity (28) of the second component when the second shape is attained through interaction of the material with the cavity. The heating means such as resistors (14) for generating the particular temperature may be included in the first element.
L'invention concerne un organe d'assemblage (12) servant à fixer un premier élément (13), tel qu'une carte de circuit imprimé, à un second élément, tel qu'un boîtier. L'organe d'assemblage comprend un premier composant (19) muni d'une broche (20) et un second composant (24) présentant une cavité (28) pour recevoir au moins une partie de la broche (20). Le premier composant ou le second composant est constitué d'un matériau adapté pour se modifier et passer d'une première forme à une seconde forme à une température particulière. La broche du premier composant (19) est adaptée pour se verrouiller dans la cavité (28) du second composant lorsque la seconde forme est obtenue par interaction du matériau avec la cavité. Un moyen de chauffage, tel que des résistances (14), peut être incorporé dans le premier élément pour générer ladite température particulière.
