The coaxial connector includes a housing that is at least partially electrically conductive, an inner electrical contact held by the housing, and an outer electrical contact. The outer electrical contact is concentrically arranged with the inner electrical contact such that the outer electrical contact is spaced radially apart from the inner electrical contact. The outer electrical contact defines a plug that is configured to be received within a receptacle of the mating connector. A coupling nut is configured to mechanically secure the electrical connector to the mating connector. The coupling nut is integrally formed with the housing and includes a radially inner surface having a thread configured to engage a thread of the mating connector. ## Claims ### Claim 1 A coaxial connector configured to mate with a mating connector, the coaxial connector comprising: a housing being at least partially electrically conductive;
