Embodiments of the disclosure are directed to a coaxial connector with a translating grounding collar for establishing a ground path with a mating connector. The coaxial connector is configured to provide an electrical connection between two mating connectors. The coaxial connector includes a housing with a first conductor and a second conductor mounted within the housing. Further, the coaxial connector comprises a grounding collar mounted to the housing to provide a grounding of the coaxial connector with a mating connector that can discharge electro-static discharge build up before connections are established between the first and second conductors and a mating connector. Thus, the coaxial connector is grounded before establishing an electrical connection between the coaxial connector and a mating connector while also compensating for tolerance stack variability in the coaxial connector. Thus, a continuous and reliable electrical and grounding contact between the connectors can be made through the coaxial connector.

A terminal-equipped wire configured by crimping a pair of barrel pieces provided on a terminal to an external sheath of a wire, the external sheath being provided on an outer circumferential surface of a core wire. The pair of barrel pieces are wrapped around the external sheath into a polygonal tube shape that has a plurality of corner portions in a circumferential direction of the external sheath, leading end edges of the pair of barrel pieces are arranged on opposite sides of at least one corner portion out of the plurality of corner portions.

An inner contact for a coaxial connector includes: an elongate, generally cylindrical body having a longitudinal axis and first and second opposed ends; and a plurality of spring fingers extending from the first end of the body generally parallel to the longitudinal axis, each of the spring fingers having a projection extending radially inwardly from a free end thereof. Each spring finger is separated from each of its immediately adjacent spring fingers by a slot. Each of the projections has opposed side edge portions, and wherein the side edge portions incline with increasing distance from an adjacent slot.
