Easily assembled coaxial cable and connector with rear body
A coaxial cable-connector assembly includes a coaxial cable, a coaxial connector, and a rear body. The coaxial cable includes: an inner conductor; a dielectric layer circumferentially surrounding the inner conductor; an outer conductor circumferentially surrounding the dielectric layer, the outer conductor having an inner surface and an outer surface; and a jacket circumferentially surrounding the outer conductor. The coaxial connector includes: an inner contact electrically connected with the inner conductor; an outer connector body spaced apart from and circumferentially surrounding the inner contact, the outer connector body including a first securing feature; and a dielectric spacer interposed between the inner contact and the outer body. The rear body has a main section and a front collet with forwardly-extending fingers, the fingers engaging the outer surface of the outer conductor of the cable, the fingers including a second securing feature, wherein the second securing feature engages the first securing feature to maintain the outer connector body and the rear body in position on the cable.
