Specific embodiment
The utility model as shown in figures 1 to 6, including preceding connection shell 2, rear connection shell 4, inner conductor 5, fixed insulation branch
Support 6, support bushing 7 and coaxial support 8,
The inner conductor 5 is equipped with spaced groove 1 and groove 2 52, and the fixed insulating supporting 6 is connected to
In groove 1, the support bushing 7 is set on fixed insulating supporting, and the coaxial support 8 is connected in groove 2 52；
Connection shell 2 has preceding stepped hole before described, and the preceding stepped hole includes the threaded hole 21 set gradually, preceding accommodating
Hole 22 and preceding mesoporous 23,
Connection shell 4 has a rear stepped hole after described, it is described after stepped hole include the rear accommodating hole 41 that sets gradually and after
Mesoporous 42, the end surface that the rear connection shell 4 is located at rear accommodating hole are equipped with external screw thread, connect shell 4 after described and pass through spiral shell
