Technical field
The present invention relates to microwave communication field, particularly relates to a kind of radio frequency (RF) coaxial connector.
Background technology
Current straight bent angle radio frequency (RF) coaxial connector typically uses two agent structures to be mutually connected vertically design, this
The major defect of the elbow radio-frequency (RF) coaxial device existence planting structure is:
1), structure complicated, its electric property is wayward, it is also difficult to adjusting, return loss commonly reaches
22.1dB, during production in enormous quantities, quality stability is poor.
2), inner wire use mode of grooving, when being connected with feeder line inner wire, feeder line inner wire is due to feeder line
Burr does not goes to the greatest extent, or inner wire is strutted and ruptures by bending, external force, so feeder line wire stripping requires the highest, and
It is difficult to clamping, reduces the reliability that product uses, therefore this type of adapter quality is on the low side.
3), the spring structure that uses of flexible clamp piece, when this structure is easily caused feeder line attaching easily and spring
Generation comes off, and assembling complexity.
4), adapter two outer conductor junction be designed as square, thus volume is relatively big, Heavy Weight, and this
Class adapter high expensive, certainly will cause the waste of copper material resource, to the city of product as continued large-scale promotion
Field competition brings immense pressure.
For problem above, need badly and a kind of to assemble the radio frequency (RF) coaxial connector simple, attachment structure is stable,

Detailed description of the invention
Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.
Due in prior art, in adapter, the outer conductor flexible clamp piece used that is connected with feeder line outer conductor uses
Spring structure, easily produce with spring when this structure is easily caused feeder line attaching and come off, and assembling is answered
Miscellaneous.For solving this problem, present solution provides a kind of radio frequency (RF) coaxial connector, Fig. 1 is that the present invention is specifically real
The decomposition texture schematic diagram of the radio frequency (RF) coaxial connector that the mode of executing provides；Fig. 2 is the specific embodiment of the invention
The installation diagram of the radio frequency (RF) coaxial connector provided.As depicted in figs. 1 and 2, radio frequency (RF) coaxial connector includes one
Outer conductor 9, described outer conductor 9 center offers a cavity, and being provided with one in the cavity of described outer conductor 9 can be with
The inner wire 7 that feeder line inner wire connects, after one end that described outer conductor 9 is provided with inner wire 7 is also associated with one
Swivel nut 2, described rear thread sleeve 2 front end is placed in described outer conductor 9 cavity, which is provided with for fixing outside feeder line
The flexible clamp piece 4 of conductor.
Preferably, described rear thread sleeve 2 front end offers screw thread, can screw and be placed in described outer conductor 9 cavity,
And sealed by a sealing member 3, in described rear thread sleeve 2, intracavity is provided with sealing ring 1, and by sealing ring 1
Seal with feeder line 10.
The spring fastener in prior art construction can be replaced due to described flexible clamp piece 4.So this radio-frequency (RF) coaxial
Adapter assembling is simple, and attachment structure is stable, reliable, feeder line outer conductor and outer conductor difficult drop-off.
In the present embodiment, preferably, described rear thread sleeve 2 front end offers an annular opening groove,
Described flexible clamp piece 4 is placed in described open slot.
In the present embodiment, as further preferred version, described flexible clamp piece 4 is rounded groove lasso.
This rounded groove lasso can replace the spring fastener in prior art construction, is designed as snapping in described rear thread sleeve 2
In, and will not from rear thread sleeve 2 free dropping.
In the present embodiment, as further preferred version, described rounded groove lasso is provided with protrusion
Draw-in groove.Described protrusion draw-in groove makes to be easier to feeder line 10 assembling.
When feeder line loads in rear thread sleeve, described protrusion draw-in groove just snaps in the trough of feeder line outer conductor, thus
Making to be connected between feeder line with adapter more reliable, clamping performance is good, and has good electric property, its time
Ripple loss has been reached 30.0dB by original 22.1dB, improves product competitiveness commercially.
Owing to, in prior art, inner wire uses mode of grooving, when being connected with feeder line inner wire, in feeder line
Conductor does not goes to the greatest extent due to feeder line 10 burr, or inner wire is strutted and ruptures by bending, external force, so feeder line 10
Wire stripping requires the highest, and is difficult to clamping, reduces the reliability that product uses, therefore this type of adapter quality
On the low side.
For solving this problem, in the present embodiment, preferably, the inwall of described outer conductor 9 is opened
It is provided with a groove, in described groove, is provided with nylon bush 6.
In the present embodiment, preferably, described nylon bush 6 rear end is provided with lining 5, described lining
One end and the described rear thread sleeve 2 of 5 connect.
Nylon bush 6 is placed in groove, encases the most simultaneously, effectively avoid feedback at inner wire 7 fluting
Line inner wire burr does not goes to the greatest extent, or bending, ruptures because inner wire 7 is strutted by external force.
In the present embodiment, preferably, it is provided with one between the 9 of described inner wire 7 and described outer conductor
Insulator 8, described insulator 8 one aspect can be used for isolating inner wire 7 with outer conductor 9；The most absolutely
Edge 8 can support described inner wire 7.
In the present embodiment, preferably, at described insulator 8 endoporus and outer radius is equipped with sealing
Circle, described sealing ring serves good sealing function.
Owing to, in prior art, adapter two outer conductor junction is designed as square, thus volume is relatively big,
Heavy Weight, therefore this type of adapter high expensive, certainly will cause the wave of copper material resource as continued large-scale promotion
Take, bring immense pressure to the market competition of product.
For solving this problem, in the present embodiment, preferably, the profile of described outer conductor is pole
Shape, and be connected two outer conductors be mutually perpendicular to.Concrete, outside the rear end of the outer conductor of front side is with rear side
The front end of conductor combines, and both junctions are pole shape.
Owing to described outer conductor profile uses pole design, this design can reduce the waste of copper material resource, institute
The space taken is the least, can shorten the length of outer conductor, thus make the structure of whole adapter more step up
Gather, alleviate its weight, provide cost savings.
The know-why of the present invention is described above in association with specific embodiment.These describe and are intended merely to explain this
The principle of invention, and limiting the scope of the invention can not be construed to by any way.Based on herein
Explaining, those skilled in the art need not pay performing creative labour can associate other tool of the present invention
Body embodiment, within these modes fall within protection scope of the present invention.
