Problems solved by technology

[0003] Since the medium of the air cable is air, the inner conductor and the outer conductor are only fixed by a layer of spiral insulating bushing, and the original structure has no bevel on the bushing (such as figure 1 shown), the outer conductor of the cable cannot be clamped after the front shell and the rear shell are tightened. Due to the special structure of the air cable, when the connector is subjected to external force, there will be a slight movement between the outer conductor and the inner conductor of the cable, resulting The order intermodulation value is unstable

Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0014] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0015] Such as Figure 2~3 As shown, a low intermodulation air cable connector includes a front shell 1, a rear shell 2 and a rear nut 3, and an insulator A11, an insulator B12, an insulator C13, an inner conductor 14, and a bushing are arranged in the front shell 1 15. A hollow circular truncated structure 4 is integrally provided at the contact point between the bush 15 and the front end of the rear casing 2 (cable front end), with a triangular radial cross-section; the side wall of the circular truncated ...

Abstract

The invention relates to a low-intermodulation air cable connector, and the connector comprises a front housing, a rear housing, and a rear nut. The interior of the front housing is provided with an insulator A, an insulator B, an insulator C, an internal conductor, and a lining. A contact part of the lining with the front end of the rear housing is provided with a hollow circular truncated cone structure through one-time molding, wherein the cross section of the hollow circular truncated cone structure is shaped like a right-angle triangle. A side wall of the hollow circular truncated cone structure abuts against a cable external conductor. The connector clamps the cable external conductor through the circular truncated cone structure, enables the cable external connector and the internal conductor to be stable and reliable, and improves the intermodulation stability of an air cable assembly.

Description

technical field [0001] The invention relates to a cable connector, and specifically discloses a low intermodulation air cable connector. Background technique [0002] Air cable is a new type of radio frequency coaxial cable, which uses air as its medium. The advantage is that the air medium is less affected by temperature, and the electrical performance is stable. At the same time, the air medium also greatly reduces the manufacturing cost. [0003] Since the medium of the air cable is air, the inner conductor and the outer conductor are only fixed by a layer of spiral insulating bushing, and the original structure has no bevel on the bushing (such as figure 1 shown), the outer conductor of the cable cannot be clamped after the front shell and the rear shell are tightened. Due to the special structure of the air cable, when the connector is subjected to external force, there will be a slight movement between the outer conductor and the inner conductor of the cable, resulting...
