The male connector includes a male substrate and a shielding case covering the male substrate. The female connector includes a female substrate and a shielding frame having the female substrate disposed therein. Multiple bumps which are distributed along an inner peripheral wall of the shielding case are disposed on at least one of the inner peripheral wall of the shielding case and an outer peripheral wall of the shielding frame, and a distance between every two adjacent bumps is less than or equal to one quarter wavelength of the operating frequency of the radio-frequency connector assembly. Signals in all directions can be shielded in the connector, effectively improving the shielding effect of the radio-frequency connector and the electrical properties of the radio frequency connector. ## Claims ### Claim 1 A radio-frequency connector assembly, comprising: a male connector; and a female connector plugged and matched with the male connector, the male connector comprising a male substrate, the female connector comprising a female substrate, the male connector further comprising a shielding case which covers the male substrate, the female connector further comprising a shielding frame, the female substrate being disposed in the shielding frame which is covered with the shielding case, wherein multiple bumps which are distributed along an inner peripheral wall of the shielding case are disposed on at least one of the inner peripheral wall of the shielding case and an outer peripheral wall of the shielding frame, and a distance between every two adjacent bumps is less than or equal to one quarter wavelength of an operating frequency of the radio-frequency connector assembly. ### Claim 2 (depends on 1) The radio-frequency connector assembly according to claim 1, further comprising: a radio-frequency line and a circuit board, wherein the male connector is connected to the radio-frequency line, and the shielding case is conductive with a ground terminal of the radio-frequency line, and the female connector is connected to the circuit board and is of a peripherally-seamless structure, a bottom of the shielding frame contacts with the circuit board, and an annular contact region is formed. ### Claim 3 (depends on 2) The radio-frequency connector assembly according to claim 2, wherein an edge guard which extends outwards is disposed at the bottom of the shielding frame. ### Claim 4 (depends on 1) The radio-frequency connector assembly according to claim 1, wherein the shielding case comprises a top plate, and a peripheral plate is arranged on an edge of the top plate and is a of peripherally-closed structure with a line inlet. ### Claim 5 (depends on 1) The radio-frequency connector assembly according to claim 1, wherein the shielding case is buckled on the shielding frame through the bumps, and slots matched with the bumps are formed in regions, corresponding to the bumps, of the inner peripheral wall of the shielding case or of the outer peripheral wall of the shielding frame. ### Claim 6 (depends on 1) The radio-frequency connector assembly according to claim 1, wherein the male substrate is provided with a male signal terminal, and the female substrate is provided with a female signal terminal matched with the male signal terminal. ### Claim 7 (depends on 1) The radio-frequency connector assembly according to claim 1, wherein the male substrate is provided with a plurality of male signal terminals, and every two adjacent male signal terminals, of the plurality of male signal terminals, are isolated by a spacer, which is conductive with the shielding case, a plurality of male substrates and a plurality of shielding frames are disposed in the female connector, each of a plurality of female substrates is in a one-to-one correspondence with a shielding frame of a plurality of shielding frames, each female substrate is provided with a female signal terminal matched with one of the male signal terminals, every two adjacent shielding frames are fixedly connected, and the spacer is inserted between two adjacent shielding frames, so that signal interference between the signal terminals is avoided. ### Claim 8 (depends on 7) The radio-frequency connector assembly according to claim 7, wherein multiple protrusions which conductively contact with the shielding frames are disposed on two sides of the spacers, and a distance between every two adjacent protrusions in a lengthwise direction of the spacers is less than or equal to one quarter wavelength of the operating frequency of the radio-frequency connector assembly. ### Claim 9 (depends on 7) The radio-frequency connector assembly according to claim 7, wherein the shielding case comprises a top plate, and all regions of top surfaces of the spacers conductively contact with the top plate. ### Claim 10 (depends on 9) The radio-frequency connector assembly according to claim 9, wherein a peripheral plate is disposed on an edge of the top plate and is a peripherally-closed structure with a line inlet, and a gap is reserved between a front end face of each spacer and the peripheral plate; or, at least one part of a front end face of each spacer conductively abut against the peripheral plate.
