High temperature magnetic localization appearance single core cable head harness

The utility model discloses a high temperature magnetic localization appearance single core cable head harness, the control system who sets up in shell, inner chamber, control system still are provided with baroceptor and temperature sensor, still be provided with the thermal insulation material filling layer on the shell, the inner chamber is the vacuum cavity. The adoption sets up the insulatinglayer on the shell, thereby ensure that the ambient temperature of system's work does not rise along with ambient temperature's rising, it is thermal -insulated through thermal insulation material filling layer and vacuum cavity, make thermal -insulated effect better, in order to guarantee the long -time normal work of instrument, the temperature gradient in the stratum solves owing to being about 3 DEG C / 100m, 3000~5000m's oil well about 90~150 DEG C of temperature in the pit then, then can be higher to the ultradeep well temperature, for the normal work of guaranteeing the fiber optic gyroscope system, the instru
