Embodiment
Below in conjunction with specific embodiment, the specific embodiment of the present invention is described in detail:
As shown in Figure 1, radio frequency (RF) coaxial connector of the present invention comprises socket and the plug with socket socket connection, is applied to the transmission of multi-channel radio frequency signal between circuit board to circuit board, between circuit board to module, between module to module and power; Socket comprises the first shell 3, first inner wire 1 and is arranged on the first insulator 2 between the first shell 3 and the first inner wire 1; Plug comprises second housing 6, the 3rd shell 10, second inner wire 5, the 3rd inner wire 12, second insulator 4, the 3rd insulator 8 and the 4th insulator 11; Second housing 6 and the 3rd shell 10 are fixed to prevent second housing 6 from coming off by back-up ring 7; Second inner wire 5 gland is connected to the 3rd inner wire 12, second insulator 4, the 3rd insulator 8 and the 4th insulator 11 and is arranged at second housing 6, between the 3rd shell 10, second inner wire 5 and the 3rd inner wire 12.
As shown in Figure 2, the first gap 17 is provided with between the second inner wire 5 and the 3rd inner wire 12; The second gap 13 is provided with between second housing 6 and back-up ring 7; Third space 14 that radial direction and scope are axially 0.2 ~ 1.0mm, the 4th gap 15 and the 5th gap 16 is provided with between second housing 6 and the 3rd shell 10, also be provided with spring 9 between second housing 6 and the 3rd shell 10, the elastic force of this spring 9 ensure that the axial location between second housing 6 and the 3rd shell 10; Large radial direction and axial tolerance can be realized when these gaps and spring structure ensure that plug and socket plug together, simultaneously due to the cushioning effect of spring, when plug and socket plug together, avoid hard impact, softer when multi-channel rf is plugged together simultaneously.
