Description
Technical field
The present invention relates to a kind of connector, specially a kind of SMA connectors without inner wire for connecting RG402.
Background technology
At present, SMA connects the CA cable assembly range of application of RG402 widely, should mainly as radio frequency wire jumper
For equipment, the inside of cabinet, the signal transmission between connection different port.As shown in Fig. 2 due to tradition
Defect of SMA types connector when designing, cause the assembly technology of product complicated, it is low using working frequency range,
Part is more, uniformity is poor, and the process-cycle is long, it is impossible to used in narrow space, is mainly manifested in：
1st, weld complicated, not only peel off the inner core of radio-frequency cable, and in advance in the installation of inner wire 5
One section of welding wire is placed in the inside in hole 51, reuses electric resistance welding and welds the inner core of inner wire 5 and radio-frequency cable
Get up, because the inner wire of SMA is thinner, during being welded, easily burn the moment of inner wire 5,
Cause it is bad with scrap；
2nd, outer conductor welding machine is bad, and traditional SMA tail portion of connector welds the afterbody of shell 6 position of radio-frequency cable
Although putting also be provided with welding inclined-plane 61, because the wall thickness of shell 6 is limited, therefore welding inclined-plane 61
Chamfering be only 0.2mm, during welding, scolding tin easily outflows, and not only influences the outward appearance of product, and causes void
Weldering；
3rd, the mounting means of swivel nut 7 is snap ring-type mechanism, causes that axial rotation can only be carried out, it is impossible to carry out
The movement of radial direction, when space requirement stricter place, installs extremely inconvenience.
The content of the invention
The technical problem to be solved in the present invention is to overcome existing defect, there is provided a kind of stable performance, assembling procedure
Less, assemble that simple, uniformity is good, part is few, low cost, working frequency range it is high, can be in the frequency of 0-24GHz
The SMA connectors without inner wire for connecting RG402 being operated under section.
In order to solve the above-mentioned technical problem, the invention provides following technical scheme：
The present invention provides a kind of SMA connectors without inner wire for connecting RG402, including the insulation being coaxially disposed
Medium, outer conductor, sealing ring and hexagonal swivel nut, are provided with the dielectric in the endoporus of the outer conductor,
The hexagonal swivel nut is arranged on the outer conductor.
Used as a preferred technical solution of the present invention, the forward position in the outer conductor inside is provided with fixation
Ring, the outer conductor outside is provided with baffle ring, the afterbody welding radio frequency electrical of the outer conductor near middle position
The position of cable is provided with scolding tin disk.
As a preferred technical solution of the present invention, movement is provided with the inner circle circumferential direction of the hexagonal swivel nut
Platform and shifting chute.
Used as a preferred technical solution of the present invention, the dielectric is the polytetrafluoroethyl-ne of diameter 2.92mm
The column of alkene material, the dielectric middle part is provided with the centre bore of a diameter of 0.9mm.
The beneficial effect that is reached of the present invention is compared with prior art：
1st, the SMA connectors without inner wire for connecting RG402 of the invention, are to be led in its own is not provided with
Body, and hexagonal swivel nut can move axially and radial rotating, when running into less installing space, can first by six
A segment distance is moved after the swivel nut of angle, after inner wire is aligned, then is screwed being pushed away before hexagonal swivel nut；
2nd, the outside diameter of dielectric be 2.92mm, center-hole diameter is 0.9mm, this size exactly with
The size of the correlated parts of RG402 is completely the same, and the diameter that SMA inner wires front end coordinates is interior with RG402
Core diameter is completely the same so that after can directly the inner wire of RG402 be peeled off, pass the center of dielectric
Hole, the inner wire for substituting connector, it is to avoid inner wire weld when human and material resources and scrap, while
In the welding being attached between device and radio-frequency cable, the compensation problem without considering transition position, uniformity is good
It is good, and due to the insulator of the diameter than traditional SMA connectors of connector built-in electrical insulation medium of the invention
Diameter is small, and the conventional cut-off frequency range of SMA is 18GHz, and the connector cut-off frequency range in the present invention can reach
To 24GHz；
3rd, present invention employs brand-new frame mode so that stable performance, assembling procedure is few, assembling is simple,
Uniformity is good, part is few, low cost, and working frequency range is high, can be operated under the frequency range of 0~24GHz,
With very strong competitive advantage.
