  • Publication number: 20230335948
    Abstract: A connector includes a back housing, a front shell having a barrel portion and a grounding portion continuous with a rear portion of the barrel portion, and a cover shell. The cover shell has a contacting portion contacting a rear end upper portion of the front shell, a catching portion catching on the grounding portion, and a spring portion elastically deformed by catching of the catching portion. The elastic deformation of the spring portion causes the cover shell to contact the back housing while pressing the back housing frontward, and to contact the front shell while pressing the rear end upper portion of the front shell upward at the contacting portion.
