The function of portion switch jaw contact contact, and assume responsibility for the effect being connect with microwave switch external signal terminal.Microwave switch leading structure
Middle inner conductor component is more complex, the function that insulator with matching plays positioning inner wire, dielectric supports.Tradition
Solution be to design an annular positioning groove in interior insulator, by the longitudinally slit half of insulator in assembling process, use
Special tooling struts insulator, after inner wire is put into insulator after position, then insulator is pressed.The insulator of pressing is no longer
It is a complete dielectric support, incision site produces the air gap, and the field strength born is made to become smaller.Cause in logical power
When, reduce the power tolerance index of microwave switch.Dielectric constant becomes uneven after insulator is longitudinally slit simultaneously, makes microwave
Mismatch occurs for the impedance matching in leading channel, to affect the RF index of microwave switch.And the prior art was being assembled
Insulator is cut in journey, assembly is time-consuming and laborious, and molecule is also easy to produce in cutting process and there is the risk for introducing fifth wheel.
Utility model content
It is interior the technical problem to be solved by the present invention is to provide a kind of linear large power microwave switch compound conductor component
Conductor improves the electric field strength between internal and external conductor, in identical structure using the composite structure of plug connector and contact contact
When size, the power tolerance of microwave switch is made to greatly improve.
The technical solution of the utility model is：
Linear large power microwave switch compound conductor component, includes outer conductor, be set to inner wire in outer conductor and
It is set to the insulator that insulating supporting inner wire is used between outer conductor and inner wire；The inner wire include plug connector and
Contact contact, the plug connector is stepped cylinder, and the one end of plug connector is provided with internal thread jack, plug connector it is another
One end is provided with pin jack, and the contact contact is stepped cylinder structure, and outer end sequentially becomes to inner end diameter
It is small, it contacts and is provided with inside and outside the first air vent penetrated through at the central axes of contact, contact and be provided on the outer wall of contact inner end
External screw thread, the inner end for contacting contact are extend into the internal thread jack of plug connector, and the inner end of contact contact is inserted with internal thread
There are gap between the bottom end in hole, the second air vent is provided on the plug connector side wall and positioned at the periphery in gap.
The contact contact includes inner end, middle part and outer end, and the middle part and outer end for contacting contact are extend into
It outside plug connector, and contacts and resists the one end face that plug connector is provided with internal thread jack in the middle part of contact, contact the outer end of contact
Portion extend into outside insulator and resists the outer end face of insulator.
The insulator includes inner insulator and external insulator, the inner end of inner insulator and the inner end phase of external insulator
Mutual grafting, the plug connector are provided with concordant with the outer end face of inner insulator, the described contact in other end of pin jack
The outer end of contact extend into outside external insulator and resists the outer end face of external insulator.
The aperture of first air vent and the second air vent is identical, is 0.5mm.
The advantages of the utility model：
(1), the inner wire of the utility model uses plug connector and contacts the composite construction of contact, plug connector and contact contact
It is inserted into and screws from the both ends of insulator respectively, ensure that the insulator supported as dielectric is not cut open, improve inside and outside
Electric field strength between conductor makes the power tolerance of microwave switch greatly improve in identical structure size；
(2), the outer end face and the switch jaw contact inside microwave switch of contact contact, pin jack and the external world of plug connector
Connection is realized in butt end, to form HIGH-POWERED MICROWAVES signal transmission link, the first air vent being arranged on inner wire and second
Air vent plays the role of discharging residual gas；When transmitting high-power signal, the inner wire temperature rise of transmission link causes interior
The volume change of residual gas around conductor and inner wire discharges the residual gas of threaded connection place by two air vents
Body avoids the phenomenon that residual gas generates ionic discharge in high-power signal transmission process.
