Description

A kind of SMA connector without inner wire connecting RG402

Technical field

The utility model relates to a kind of connector, is specially a kind of SMA connector without inner wire connecting RG402.

Background technology

At present, SMA connects the cable assembly range of application of RG402 widely, is applied to equipment mainly as radio frequency wire jumper, the inside of cabinet, connects the Signal transmissions between different port.As shown in Figure 2, due to defect when traditional SMA type connector designs, cause the assembly technology of product complicated, use working frequency range low, part is many, consistency is poor, and the process-cycle is long, cannot use, be mainly manifested in narrow space:

1, welding is complicated, not only the inner core of radio frequency cable to be peeled off, and place one section of welding wire in the inside of the installing hole 51 of inner wire 5 in advance, re-use electric resistance welding the inner core of inner wire 5 with radio frequency cable is welded, because the inner wire of SMA is thinner, carrying out, in the process of welding, very easily inner wire 5 being burnt instantaneously, cause bad with scrap;

2, outer conductor welding machine is bad, although shell 6 tail position of traditional SMA tail portion of connector welding radio frequency cable is also provided with welding inclined-plane 61, but because the wall thickness of shell 6 is limited, the chamfering of therefore welding inclined-plane 61 is only 0.2mm, during welding, scolding tin very easily outflows, and not only affects the outward appearance of product, and causes rosin joint;

3, the mounting means of swivel nut 7 is snap ring-type mechanism, causes carrying out axial rotation, cannot carry out radial movement, when the place stricter for space requirement, installs very inconvenience.

Utility model content

The technical problems to be solved in the utility model overcomes existing defect, a kind of stable performance is provided, assembling procedure is few, assembling is simple, consistency is good, part is few, cost is low, working frequency range is high, the SMA connector without inner wire connecting RG402 of work can be carried out under the frequency range of 0-24GHz.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme:

The utility model provides a kind of SMA connector without inner wire connecting RG402, comprise the coaxial dielectric, outer conductor, sealing ring and the hexagonal swivel nut that arrange, be provided with described dielectric in the endoporus of described outer conductor, described hexagonal swivel nut is arranged on described outer conductor.

As a kind of optimal technical scheme of the present utility model, the inner forward position of described outer conductor is provided with retainer ring, and described outer conductor is outside is provided with baffle ring near middle position, and the position of the afterbody welding radio frequency cable of described outer conductor is provided with scolding tin dish.

As a kind of optimal technical scheme of the present utility model, the inner periphery direction of described hexagonal swivel nut is provided with travelling carriage and shifting chute.

As a kind of optimal technical scheme of the present utility model, described dielectric is the column of the polytetrafluoroethylmaterial material of diameter 2.92mm, is provided with the centre bore that diameter is 0.9mm in the middle part of described dielectric.

The beneficial effect that compared with prior art the utility model reaches is:

1, the SMA connector without inner wire connecting RG402 of the present utility model, be that himself does not arrange inner wire, and hexagonal swivel nut can move axially and radial rotating, when running into less installing space, first can move a segment distance by after hexagonal swivel nut, after inner wire is aligned, then screw pushing away before hexagonal swivel nut;

2, the outside diameter of dielectric is 2.92mm, center-hole diameter is 0.9mm, this size is exactly completely the same with the size of the correlated parts of RG402, and the inner core diameter of the diameter that SMA inner wire front end coordinates and RG402 is completely the same, make it possible to directly by after the stripping of the inner wire of RG402, pass the centre bore of dielectric, for the inner wire of alternative connector, manpower when avoiding inner wire to weld, material resources and scrapping, simultaneously when carrying out welding between connector with radio frequency cable, without the need to considering the compensation problem of transition position, consistency is good, and due to the diameter of connector built-in electrical insulation medium of the present utility model less than the diameter of the insulator of traditional SMA connector, the routine cut-off frequency range of SMA is 18GHz, and the connector cut-off frequency range in the utility model can reach 24GHz,

3, the utility model have employed brand-new frame mode, makes stable performance, and assembling procedure is few, assembling is simple, consistency is good, part is few, cost is low, and working frequency range is high, can carry out work, have very strong competitive advantage under the frequency range of 0 ~ 24GHz.
