Abstract

La présente invention concerne un ensemble lentille étanche à un débordement de colle (2) et un dispositif électronique (1). L'ensemble lentille étanche à un débordement de colle (2) comprend un barillet de lentille (100) et un groupe de lentilles (200) reçu dans le barillet de lentille (100). Le barillet de lentille (100) comprend une paroi interne (130) proche d'un axe optique, une paroi externe (140) située à l'opposé de la paroi interne (130) et une face d'extrémité côté image (110) reliant la paroi interne (130) à la paroi externe (140). Une rainure de débordement de colle (120) est située sur le barillet de lentille (100). La rainure de débordement de colle (120) a une entrée (122). L'entrée (122) est située sur la face d'extrémité côté image (110), entre la paroi interne (130) et la paroi externe (140). En fournissant la rainure de débordement de colle (120) sur le barillet d'objectif (100) et en plaçant l'entrée (122) de la rainure de débordement de colle (120) sur la face d'extrémité côté image (110), lorsque l'ensemble lentille (2) doit être collé à un autre composant, l'excédent de colle peut entrer dans la rainure de débordement (120) à partir de l'entrée (122) et ne déborde pas facilement d'un côté de la face d'extrémité côté image (110), ce qui permet de réduire le débordement d'une colle sur l'ensemble lentille (200) et d'assurer une bonne qualité d'imagerie de l'ensemble lentille (2).
