Abstract

L'invention concerne un connecteur de fibre optique qui comprend un adaptateur (40) et une fiche. La fiche comprend un couvercle de cadre externe (1), un couvercle de cadre interne (2), un composant de partie centrale de fiche (3), une porte de protection (4) et un ressort de torsion (5). Le composant de partie centrale de fiche (3), le couvercle de cadre interne (2) et le couvercle de cadre externe (1) sont agencés de façon séquentielle en allant de l'intérieur vers l'extérieur. Un premier axe de pivot (41) est agencé sur une extrémité supérieure de la porte de protection (4), et un premier trou de pivotement (411) est agencé dans une direction axiale du premier axe de pivot (41). Un second axe de pivot (11) s'avance vers l'intérieur depuis une paroi latérale du couvercle de cadre externe (1), et le second axe de pivot (11) s'insère dans le premier trou de pivotement (411). Le ressort de torsion (5) s'enroule autour d'un côté externe du premier axe de pivot (41), une première extrémité du ressort de torsion (5) déploie un premier bras d'extension (51), et le premier bras d'extension (51) est pressé sur l'avant (42) de la porte de protection (4). Le dos (43) de la porte de protection (4) est placé contre une extrémité avant du composant de partie centrale de fiche (3). Lorsque la fiche est retirée de l'adaptateur (40), la porte de protection (4) tourne sous l'action du ressort de torsion (5), et le dos (43) de la porte de protection (4) est placé contre l'extrémité avant du composant de partie centrale de fiche (3), ce qui permet d'obtenir un effet d'ombre automatique et d'empêcher la poussière ; lorsque la fiche est insérée dans l'adaptateur (40), le composant de partie centrale de fiche (3) pousse la porte de protection (4) pour qu'elle tourne afin de s'ouvrir, ce qui permet que la fiche soit prête à l'emploi.
