Abstract

The invention discloses a split type radio frequency coaxial adaptor which comprises a nut, a casing body, an outer conductor and inner conductors. The casing body comprises an insertion head end and an insertion base end, the outer conductor is arranged in the casing body and is in interference fit with the casing body, the inner conductors are arranged in the outer conductor, and the nut is arranged at the insertion head end of the casing body. The inner conductor comprises a first inner conductor and a second inner conductor, the two ends of the first inner conductor are provided with a first insertion pin and a first insertion hole respectively, the two ends of the second inner conductor are provided with a second insertion pin and a second insertion hole respectively, the first insertion pin is located at the insertion head end of the casing body, the second insertion pin is located in the first insertion hole, and the second insertion hole is located in the insertion base end of the casing body. The processing technology of a radio frequency electric cable adaptor is simplified, production efficiency is improved, production cost is reduced, particularly, such as a split type 1.85mm radio frequency coaxial adaptor, and the voltage standing wave ratio of the adaptor is smaller than or equal to 1.45 under DC-65GHz.

Description

technical field

[0001] The invention relates to a split-type radio frequency coaxial adapter, which belongs to the technical field of electrical connectors. Background technique

[0002] The 1.85mm connector adapter can work up to 65GHz, with a wide operating frequency and small size. It can be applied to microwave and millimeter wave coaxial signal transmission. Because it works in the millimeter wave band, it is extremely difficult to design and process. In China, 1.85mm connection The adapter is still in the trial stage, and the highly reliable 1.85mm adapter is blank.

[0003] In the 1.85mm RF coaxial adapter in the prior art, the inner conductor is usually a one-piece structure, although it is easy to process, but the electrical performance is insufficient; the material selection of the outer conductor also needs to be improved, and it is usually difficult to achieve low Dielectric constant, choosing a material with a low dielectric constant is difficult to prove the c...
