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

A kind of low intermodulation air cable connector
Technical field
The present invention relates to cable connector, specifically disclose a kind of low intermodulation air cable connector.
Background technology
Air cable is a kind of novel radio frequency coaxial-cable, and adopt air as its medium, advantage is that air dielectric temperature influence is little, and electric property is stablized, and air dielectric also greatly reduces manufacturing cost simultaneously.
Medium due to air cable is air, fix by means of only a helical layer insulating bushing between inner wire and outer conductor, original structure does not have oblique angle (as shown in Figure 1) on lining, after front casing and rear casing screw, cannot clamping cables outer conductor, due to the special construction of air cable, when connector is subject to External Force Acting, slight movement can be produced between cable outer conductor and inner wire, cause third order intermodulation value unstable.
Summary of the invention
The object of the invention is to: provide a kind of air cable connector promoting air cable assembly intermodulation stability for overcoming the above problems.
The technical solution adopted in the present invention is such:
A kind of low intermodulation air cable connector, comprise front casing, rear casing and back nut, be provided with in described front casing insulator A, insulator B, insulator C, inner wire, lining, have a hollow round table structure at described lining and contact position, rear casing front end integrated setting, radial section is triangular in shape; Described frustum cone structure sidewall abuts with cable outer conductor.
In sum, owing to adopting technique scheme, the invention has the beneficial effects as follows:
The present invention carrys out clamping cables outer conductor by frustum cone structure, makes between cable outer conductor and inner wire reliable and stable, improves the intermodulation stability of air cable assembly.
Accompanying drawing explanation
Fig. 1 is prior art lining and conductive cable contacts point partial enlarged drawing;
Fig. 2 is structure chart of the present invention;
Fig. 3 is A place enlarged drawing in Fig. 2.
Mark in figure: 1, front casing; 11, insulator A; 12, insulator B; 13, insulator C; 14, inner wire; 15, lining; 2, rear casing; 3, back nut; 4, frustum cone structure.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Arbitrary feature disclosed in this specification (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
As shown in Fig. 2 ~ 3, a kind of low intermodulation air cable connector, comprise front casing 1, rear casing 2 and back nut 3, insulator A11, insulator B12, insulator C13, inner wire 14, lining 15 is provided with in described front casing 1, have a hollow round table structure 4 at described lining 15 with rear casing 2 front end (cable head end) contact position integrated setting, radial section is triangular in shape; Described frustum cone structure 4 sidewall abuts with cable outer conductor.
Be provided with external screw thread in the front end of cable, be provided with internal thread in rear casing 2 one end, with front casing 1 link, cable is threaded with rear casing 2; Both connect rear screw-in front casing 1, the lining 15 arranged inside front casing 1 abuts with cable head end (rear casing front end), because the existence of frustum cone structure 4 plays compression position-limiting action to cable outer conductor, the existence of External Force Acting also can not make location between cable inner conductor and outer conductor move namely not exist and move radially, connect reliable, improve the intermodulation stability of air cable assembly.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.

Claims (1)
