  • the individual needle-like structures 30 and 80 may have a rectangular cross-sectional shape, or may have the same width and diameter from the bases 31 and 81 fixed to the housings 10 and 60 toward the tips 32 and 82.

Abstract

Raccord de structure simple, réalisable à bas coût, de taille réduite et offrant une bonne exploitation de l'espace, avec fonctions anti-goutte et anti-poussière procurées naturellement par ce seul raccord. Spécifiquement, un raccord (1) comprend : un boîtier (10) recevant des contacts (20) et présentant une ouverture (11) pour un élément de raccord apparié ; et une pluralité de structures aciculaires isolantes souples (30) qui sont fixées au boîtier (10) de manière et recouvrent l'ouverture (11).
