Abstract

The utility model discloses an adaptor which comprises an internal conductor, an insulating body and a casing. The casing comprises a first casing and the second casing which are correspondingly arranged. The insulating body comprises a first insulating body and a second insulating body, wherein the first insulating body is filled between the internal conductor and the second casing, the second insulating body is filled between the internal conductor and the first casing, and an enclosed annular space is formed between the first insulating body and the second insulating body. Compared with a present radio frequency coaxial connector, the adaptor provided by the utility model has the advantages that the adaptor has reduced volume and reasonable structure, reduces polytetrafluoroethylene medium, is provided with standard impedance to increase air ratio, and effectively improves the frequency of use; the adaptor can be used together with a SMA connector by adopting a turnbuckle so as to enhance generality; and through tests, the adaptor has good performance, low voltage stationary wave and low loss.

Description

A kind of adapter

Technical field

The utility model relates to a kind of radio frequency (RF) coaxial connector, relates in particular to a kind of adapter.

Background technology

At present, radio frequency (RF) coaxial connector is a kind of electromechanical compo that transmits electromagnetic various port that is used for specially connecting, and it can be used for circuit board, radio-frequency module and the connection between them.Because the fast development of causes such as communication, the kind of RF coaxial connector, specifications and characteristics have proposed increasing requirement, especially the frequency range of using are proposed more requirement, constantly enlarge the scope of application and improve frequency of utilization.And existing radio frequency (RF) coaxial connector mainly is made of internal and external conductor, insulator and annex etc., and these parts tend to because in structure or the selection, existing problems more or less can not satisfy the instructions for use of product fully in assembly and installation process.

The utility model content

Goal of the invention: at deficiency of the prior art, the purpose of this utility model provides a kind of adapter, to improve the frequency of utilization of this connector, simultaneously, optimizes its performance.

Technical scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the utility model is:

A kind of adapter, comprise inner wire, insulator and shell, described shell comprises cooperatively interacting installs first shell and second shell, described insulator comprises first insulator and second insulator, described first insulator is filled between the inner wire and second shell, described second insulator is filled between the inner wire and first shell, is formed with an airtight annular space between first insulator and second insulator.

In the described airtight annular space is air dielectric.

Socket end inside at described second shell is provided with lining, and described lining is clenched week in second shell.

Socket end periphery at described first shell is provided with swivel nut, and described swivel nut is fixed on the periphery of first shell by snap ring.

Adapter of the present utility model, by between inner wire and object, filling 2 insulators, and between insulator, leave the space, the space internal memory has air dielectric, will form a normal impedance space like this, compares with the common adapter of not removing PTFE medium, improved frequency of utilization, simultaneously dimensionally, dwindled the inner space of adapter, raising once more frequency of utilization.In addition, the lining of riveting tightly in the socket inside of housing, the fixed insulation medium also can satisfy standard interface simultaneously.Socket outer setting at housing has swivel nut, can with the use that matches of SMA AN connector, make the versatility of this adapter strengthen.

Beneficial effect: adapter of the present utility model, to compare with existing radio frequency (RF) coaxial connector, typical advantage has: dwindle, reduce PTFE medium, the impedance that sets up standard increases air ratio, and is rational in infrastructure, effectively raises frequency of utilization; Select swivel nut for use, can use, strengthened versatility with the SMA AN connector; Simultaneously, through test, this adapter function admirable, voltage standing wave(VSW) is low, and loss is little.

Description of drawings

Accompanying drawing is the structural representation of adapter of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is further explained.

As shown in drawings, be adapter of the present utility model.This adapter comprises inner wire 1, lining 2, first insulator 3, second insulator 4, first shell 5, second shell 6, snap ring 7 and swivel nut 8; One end of inner wire 1 is a tubular structure, and the other end is a column structure, can be respectively be connected with supporting connector; One end of first shell 5 leaves interface, and an end of second shell 6 also leaves the interface that matches and use with the interface of first shell 5, and after the interface that uses by cooperatively interacting connected, first shell 5 and second shell 6 just formed the shell integral body of an axis; First insulator 3 is filled between the inner wire 1 and second shell 6, second insulator 4 is filled between the inner wire 1 and first shell 5, between first insulator 3 and second insulator 4, will be formed with an airtight annular space 9, in annular space 9, be filled with air dielectric, therefore just form a normal impedance space, compare with the common adapter of not removing PTFE medium, improved frequency of utilization.

At the other end of second shell 6, promptly socket end inside is provided with lining 2, when this lining 2 is used for fixing first insulator 3, also can satisfy standard interface.

At the other end of first shell 5, promptly socket end periphery is provided with swivel nut 8, and is fixed on the periphery of first shell 5 by snap ring 7, can with the use that matches of SMA AN connector, make the versatility of this adapter strengthen.
