Description
Technical field
The utility model is related to radio frequency open circuit device field more particularly to a kind of New-type radio-frequency open circuit devices.
Background technology
Radio frequency open circuit device is the terminal part for realizing radiofrequency signal total reflection function, is generally connected using polarized RF coaxial
Device is connect, therefore male open circuit device and cloudy head open circuit device can be divided into.No matter cloudy head or male open circuit device are by open circuit inner wire and outer
Conductor is constituted.To keep coaxial position relationship between open circuit inner wire and outer conductor, and realize function of open, it need to be in internal and external conductor
Between install an insulating dielectric materials, make internal and external conductor keep with one heart and electric insulation.For radio frequency connector, inner wire end
Face requires and outer conductor electrical reference face close alignment, and forbids prominent outer conductor electrical reference face.To meet this requirement, need
Accurately to adjust axial position of the open circuit inner wire in outer conductor.The method of adjustment is to apply sufficiently large axis to dielectric support
Xiang Li can be axially moveable, until inner wire end face reaches the position with outer conductor electrical reference face.
The method of existing open circuit device adjustment open circuit inner wire axial position can only be taken split due to the limitation of existing structure
Road dielectric support unidirectionally applies axial force.Since the resistance difference open circuit device that medium support is slided in outer conductor is all different, because
The mobile effect that this axial force generates is difficult to control, and can not accurately control the position of inner wire, open circuit inner wire easily occurs
The phenomenon that prominent electrical reference face.Once there is the situation, due to open circuit dielectric support can not retreat, can only along original direction after
Continuous promotion medium supports and releases outer conductor, then reloads medium support adjustment from the other end.Cause regulated efficiency relatively low.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of internal New-type radio-frequency open circuit using threaded connection
Device.
A kind of New-type radio-frequency open circuit device, including open circuit inner wire, outer conductor and dielectric support, the outer circle of the dielectric support
Face is provided with external screw thread, and the bottom of the dielectric support is provided with fixing groove；The outer conductor is provided with and dielectric support phase
The internal thread matched；The end of the open circuit inner wire opens up blind hole, is glued with the blind hole at the top of the dielectric support and fixes.
In said program, the fixing groove is one kind of flat recess, cross recess or hexagonal hole.
In said program, the external screw thread of the dielectric support and the internal thread of outer conductor are small―gap suture matching thread；It is described
When screw thread specification is less than or equal to M5, interstice coverage is in 0-0.05mm；When the screw thread specification is more than M5, interstice coverage exists
0.05-0.1mm。
The beneficial effects of the utility model are compared with prior art：By the way that dielectric support is increased external screw thread and fluting knot
Structure, while internal thread is set in outer conductor bores, the purpose of adjustment open circuit inner wire axial position is realized by screw-thread fit.It should
Displacement is controlled by thread pitch and rotation angle, and Adjustment precision can be improved by reducing screw pitch.Dielectric support both forward and reverse directions revolve
Turn can be realized open circuit inner wire back-and-forth motion.Compared with original open circuit device, novel using helicitic texture dielectric support opens
Road device substantially increases regulated efficiency.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model New-type radio-frequency open circuit device；
Reference sign:1, it opens a way inner wire, 2, outer conductor, 3, dielectric support, 4, fixing groove.
Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
As shown in Fig. 1, a kind of New-type radio-frequency open circuit device, including open circuit inner wire 1, outer conductor 2 and dielectric support 3, medium
The periphery of support 3 is provided with external screw thread, and bottom is provided with fixing groove 4, which is arranged to flat recess, cross recess or six
One kind of square hole；Outer conductor 2 is provided with the internal thread to match with dielectric support 3, meanwhile, the external screw thread of dielectric support 3 and outer
The internal thread of conductor 2 is small―gap suture matching thread, when screw thread specification is less than or equal to M5, interstice coverage in 0-0.05mm, when
When screw thread specification is more than M5, interstice coverage is in 0.05-0.1mm.The end of open circuit inner wire 1 offers blind hole, and dielectric support 3 is pushed up
Portion is glued with blind hole to be fixed.
Adjustment specific side be：The top of dielectric support 3 and the blind hole splicing of 1 end of open circuit inner wire are first fixed on one
It rises, then selects the screwdriver to match with fixing groove 4, the rotation angle of dielectric support 3 is adjusted by screwdriver, by leading outside
The internal thread structure of body 2 makes the external screw thread of dielectric support 3 connect and move axially with the internal thread of outer conductor 2, is opened to realize
Coaxial position relationship is between road inner wire 1 and outer conductor 2, until open circuit inner wire 1 reaches 2 electrical reference face of outer conductor
Position.When inner wire 1 of opening a way exceeds electrical reference face position, screwdriver reversely rotates dielectric support, until open circuit inner wire 1
Electrical reference with outer conductor 2 is in face of neat.The back-and-forth motion of open circuit inner wire 1 can be realized in the rotation of 3 both forward and reverse directions of dielectric support,
Compared with tradition opens a way device, regulated efficiency is substantially increased using the New-type radio-frequency open circuit device of helicitic texture dielectric support 3.
Above example is only to illustrate the technological thought of the utility model, and the protection model of the utility model cannot be limited with this
Enclose, it is every according to the utility model proposes technological thought, any change is made on the basis of technical solution, each falls within this reality
With in novel protected range.
