Abstract

L'invention appartient au domaine technique des composants électromécaniques et se rapporte en particulier à un connecteur. Le connecteur comprend un boîtier de connecteur. Une mâchoire de serrage est articulée sur le boîtier de connecteur. La mâchoire de serrage est dotée d'une extrémité avant utilisée pour être verrouillée et mise en correspondance avec un boîtier de connecteur d'adaptateur dans un connecteur d'adaptateur, et est en outre dotée d'une extrémité arrière utilisée pour appliquer une force pour réaliser un déverrouillage. L'extrémité arrière de la mâchoire de serrage et le boîtier de connecteur sont agencés d'une manière descendante, et une pression vers le bas de l'extrémité arrière de la mâchoire de serrage peut séparer la mâchoire de serrage du boîtier de connecteur d'adaptateur. L'extrémité arrière du boîtier de connecteur est dotée d'un écrou d'une manière filetée. L'extrémité avant de l'écrou est utilisée pour passer entre l'extrémité arrière de la mâchoire de serrage et le boîtier de connecteur. L'écrou est utilisé pour être en ajustement de blocage avec la mâchoire de serrage dans une direction haut-bas, de manière à empêcher que la mâchoire de serrage ne soit pressée vers le bas jusqu'à la position où la mâchoire de serrage est séparée du boîtier de connecteur d'adaptateur.
