Anti-misplug coaxial connector assembly
An anti-misplug coaxial connector assembly includes a female connector and a male connector. The female connector includes: a first inner conductor provided with an accommodation cavity defining a longitudinal axis; a first outer conductor; and a first insulator arranged between the first inner conductor and the first outer conductor. The male connector includes: a second inner conductor, a second outer conductor, and a second insulator arranged between the second inner conductor and the second outer conductor. The first outer conductor and the second outer conductor form radial contact by means of a resilient finger-shaped element that surrounds the second insulator. The first insulator includes a main body portion circumferentially surrounding the first inner conductor and a shoulder portion protruding outwardly along the radial direction relative to the main body portion so as to engage the first outer conductor.
