The relative dielectric constant of the insulating medium refers to that induced charges are generated when an electric field is applied to weaken the electric field, and the ratio of the original applied electric field (in vacuum) to the electric field in the insulating medium is the relative dielectric constant. That is, the relative permittivity ∈, a physical parameter that characterizes the dielectric or polarization properties of the dielectric material. The value is equal to the ratio of the capacitance of the capacitor with the same size and made by taking the predicted material as the medium and taking the vacuum as the medium, and the value of the vacuum dielectric constant is as follows: ε 0 = 8.854187817 × 10-12F/m (approximation).
The insulation medium on the peripheries of two ends of the inner conductor of the adaptor connector consists of two parts, and the relative dielectric constants of the insulation medium of the two parts are different; third insulating medium 2-3 and fourth insulating medium of said adaptor connector 2The medium 2-4 is arranged at the periphery of the end parts of the two ends of the inner conductor 2-2, and the relative dielectric constant epsilon of the fourth insulating medium 2-4 1 Greater than the relative permittivity epsilon of the third insulating medium 2-3 2 In this way, the impedance of the dielectric region of the adaptor connector 2 with a small internal relative dielectric constant is large, whereas the impedance of the dielectric region with a large internal relative dielectric constant is small; thereby forming different impedance areas in the same cavity.
When two ends of the switching connector 2 are respectively connected and meshed with the first connector 1 and the second connector 3 to have certain axial deviation, a larger high-impedance area is formed at the meshing interface part of the switching connector 2, and the invention adopts a prefabricated low-impedance area with large relative dielectric constant, so that mutual complementation and closing of impedance can be effectively formed with the high-impedance area; therefore, the negative influence of high impedance generated by the meshing gap can be compensated, and the radio frequency electrical performance of the product is improved, so that the radio frequency coaxial connector can allow larger axial offset (+/-1.2 mm); meanwhile, the fourth insulating medium is an elastic insulating medium, and the characteristics of elastic materials are utilized to tightly embrace the periphery of the inner conductor 2-2 of the adaptor connector 2, so that the inner conductor of the adaptor connector and the inner conductor of the connector are effectively engaged all the time.

As shown in fig. 4, 5, 6, 7, 8 and 9, the invention obtains a high impedance region and a low impedance region by selecting insulating media with different relative dielectric constants, and satisfies three states of a middle gap state, a maximum gap state and a minimum gap state, wherein the middle high impedance region is always compensated by the low impedance regions on two sides respectively, thereby obtaining good electrical performance in the whole gap region.

for example, the following steps are carried out: if an inclination angle of 1 ° exists, when the arrangement pitch of every two connectors is 10mm + 10mm, 5X5 arrangement =25 can be met when the axial offset is allowed to be 1mm (+/-0.5 mm), and when the axial offset is allowed to be 2.4mm (+/-1.2 mm), 13X13 arrangement =169 can be met; similar to: the offset is increased by X, which allows the square number of X matrix installations. The integrated use state of the microwave communication can be greatly satisfied.
