Abstract

The invention discloses a plug-resistant ultra-low inter-modulation radio frequency connector. The radio frequency connector comprises an inner conductor, a medium and an outer conductor, the inner conductor comprises an inner conductor and a male inner conductor, the medium is covered around the inner conductor, and the inner conductor is arranged between the male inner conductor and the outer conductor. After the inner conductor is jointed with the male inner conductor through the surrounding of the medium, the consistency of the size is guaranteed, the plugging times are greatly improved, the stability of the three-order inter-modulation value is guaranteed, the service life of a device port adaptor is prolonged, and the maintenance cost is reduced.

Description

The ultralow intermodulation radio frequency connector of a kind of anti-plug

Technical field

The present invention relates to the communication equipment technical field, be specifically related to the ultralow intermodulation radio frequency connector of a kind of anti-plug.

Background technology

Radio frequency connector is as a kind of dynamo-electric components and parts, be widely used on communication equipment, the low intermodulation jack radio frequency connector of existing 7/16 type is mainly used in all kinds of filters, the signal screening that is used for all kinds of mobile communication system, digital microwave communication system, military microwave system (radar and electronic countermeasures), as output and being connected of input port, have the characteristics such as bandwidth, insertion loss is low, power capacity is large.

Existing 7/16 type radio frequency connector, air dielectric between inner conductor outer diameter and outer conductor internal diameter, on inner wire, fluting is processed, as it is inconsistent to close up, can cause inner wire to contact with the male inner wire unreliable, intermodulation value difference or unstable is after surpassing primary standard 500 times with male plug number of times, internal conductor material also may begin fatigue, causes the third order intermodulation value to become unstable.

Summary of the invention:

The invention provides the ultralow intermodulation radio frequency connector of anti-plug, to solve the low intermodulation jack radio frequency connector of 7/16 type, intermodulation performance is not high, repeatedly plugs the intermodulation wild effect.Its concrete technical scheme is as follows:

The ultralow intermodulation radio frequency connector of described anti-plug is characterized in that this radio frequency connector comprises inner wire, male inner wire, medium and outer conductor; The wrapped outer wall that is rolled in inner wire of described dielectric ring, inner wire is arranged between male inner wire and outer conductor.

The ultralow intermodulation radio frequency connector of described anti-plug further designs and is, this radio frequency connector also comprises shell and insulator, and described inner wire, male inner wire, medium, outer conductor and insulator all arrange in the enclosure.

The ultralow intermodulation radio frequency connector of described anti-plug further designs and is, insulator is connected with outer conductor with inner wire.

The invention has the beneficial effects as follows:

1. adopt dielectric ring wrapped be rolled in make inner wire on the inner wire outer wall and the male inner wire engage after, outside dimension to inner wire has played fixation, guarantee the consistency of size, thereby greatly improved the plug number of times, also guaranteed the stability of third order intermodulation value.

2. improve the useful life of device port joint, reduced maintenance cost.

In figure: the 1-inner wire; 2-male inner wire; The 3-medium; The 4-outer conductor; The 5-insulator; The 6-shell; The 7-air dielectric.

Embodiment

As shown in Figure 1, the ultralow intermodulation radio frequency connector of the anti-plug of the present invention comprises inner wire 1, male inner wire 2, medium 3, outer conductor 4, shell 6 and insulator 5; Medium 3 is around on the outer wall that is wrapped in inner wire 1, and inner wire 1 is arranged between male inner wire 2 and outer conductor 4, and insulator 5 is connected with outer conductor 4 with inner wire 1.Inner wire 1, male inner wire 2, medium 3, outer conductor 4 and insulator 5 all are arranged in shell 6.The medium 3 that is wrapped on the outer wall of inner wire 1 is made by plastic rubber material PBTG20.

Radio frequency connector of the present invention has been improved the structure (as Fig. 2) of former 7/16 radio-frequency (RF) device, adopt the method for blending agent, replace air dielectric 7 with medium 3, medium 3 is wrapped on inner wire 1, after inner wire 1 engages with male inner wire 2, inner wire 1 outside dimension is played fixation, controlled the consistency of inner wire 1 outside dimension, thereby greatly improved the plug number of times, also guarantee the stability of third order intermodulation value, improved the useful life of device port joint, reduced maintenance cost.
