Casing is crimped on intershield crimp body aft end sleeve；Double coaxial cable external shields are crimped on outer by external shield crimping sleeve
It shields on crimp body aft end sleeve；The flexible terminal crimped is plugged on measuring probe center conductor, cap nut and measurement
Intershield of popping one's head in fastens, and outer housing is fastened with measuring probe external shield, and spring hood is fastened on shell by hood fastener
On body.
Double coaxial cables carry out wire stripping processing.
The intershield crimp body passes through screw threads for fastening with intershield connector.
The cap nut passes through screw threads for fastening with measuring probe intershield.
The outer housing passes through screw threads for fastening with measuring probe external shield.
It is obtained by the present invention to have the beneficial effect that：
The present invention has passed through the type approval test related to irradiation etc. of high temperature, sealed pressure, and has carried out impact and shock test,
It fully verifies it and disclosure satisfy that probe burn-back component and double coaxial cables under high temperature, high pressure, irradiation and graphite dust environment
Be reliably connected.
