Abstract

L'invention concerne un dispositif de verrouillage de port USB inséré dans un port USB ayant un bornier à l'intérieur de celui-ci. Un dispositif de verrouillage de port USB selon la présente invention, qui est inséré dans un port USB ayant un bornier à l'intérieur de celui-ci, comprend : un substrat ayant une pluralité de bornes USB et une partie de pénétration ; une unité de verrouillage située au niveau d'une partie inférieure du substrat, et comprenant une partie fixe fixée par rapport au substrat et une partie élastique s'étendant dans une direction oblique au niveau d'une extrémité avant de la partie fixe et ayant une pointe à une position correspondant à la partie de pénétration ; une unité de coin installée pour se déplacer le long d'une direction longitudinale au niveau d'une partie inférieure de l'unité de verrouillage ; et un bouchon pour empêcher l'unité de coin de se déplacer vers l'arrière une fois que l'unité de coin entre dans celle-ci. Lorsque l'unité de coin entre dans la partie inférieure de l'unité de verrouillage, la pointe passe à travers la partie de pénétration du substrat et est incorporée dans le bornier à une position où la pointe n'entre pas en contact avec le terminal USB prévu sur le bornier du port USB.
