Cable head structure of high-temperature pressure gauge

The utility model discloses a cable head structure of a high-temperature pressure gauge, which relates to the technical field of production well logging and intelligent well completion and comprises a main body formed by butting a fishing head, an upper sealing cylinder and a sealing joint one by one from left to right, and a contact assembly used for connecting the high-temperature pressure gauge. According to the cable head structure of the high-temperature pressure gauge, the steel pipe cable, the metal clamping sleeve type upper sealing cylinder and the sealing joint are connected in a sleeved mode, metal material clamping sleeve type sealing is achieved, then the silicone grease filling chamber is filled with high-temperature silicone grease for sealing, and the problems that in the prior art, a cable head is not high in high-temperature resistance, cannot be used at high temperature, and cannot be used at high temperature are solved. Therefore, the cable head structure of the high-temperature pressure g
