Abstract

Un dispositif de connexion comprend un câble coaxial, un connecteur métallique (03) et un manchon protecteur métallique (04), un conducteur externe (02) du câble coaxial étant connecté au connecteur métallique (03) par l'intermédiaire du manchon protecteur métallique (04), le manchon protecteur métallique (04) comprend un corps cylindrique creux (05), et le corps cylindrique creux (05) est gainé sur le conducteur externe (02) du câble coaxial. De cette manière, lorsque le câble coaxial est gainé par le manchon protecteur métallique (04), et que le conducteur externe (02) du câble coaxial est connecté au connecteur métallique (03) par l'intermédiaire du manchon protecteur métallique (04), le conducteur externe (02) du câble coaxial est moins enclin à être endommagé lors du processus de connexion de celui-ci au connecteur métallique (03).
