Abstract: A board-to-board radio frequency coaxial connector includes an adapter, a clamping socket including a first outer conductor, a first inner conductor, and a first insulator, and a fixed socket including a second outer conductor, a second inner conductor, and a second insulator. The clamping socket and the fixed socket are respectively arranged at two ends of the adaptor. The adapter includes a third outer conductor, a third inner conductor, and two third insulators. The two third insulators are respectively arranged at two ends of the third inner conductors and sleeved on an outside of the third inner conductor. Each of the two third insulators includes a body portion and an auxiliary portion. The body portion includes a second groove recessed inwardly from its outer circumferential surface. Two ends of the third outer conductor are respectively electrically connected to the first and second outer conductors.
