Abstract

An electrical probe structure includes a conductive cylinder, a first electrical connecting port and a probe assembly. The conductive cylinder for being fixed to the base plate has thereinside a sliding tunnel. The first electrical connecting port is electrically connected to the conductive cylinder. The at least one flexible conductive tube is furnished inside the sliding tunnel. The at least one probe assembly includes a first needle cylinder and a first probe. The first needle cylinder, slidably penetrating the conductive cylinder, electrically contacts the at least one flexible conductive tube so as to have the first needle cylinder to electrically connect the first electrical connecting port via the at least one flexible conductive tube and the conductive cylinder. The first probe is mounted and electrically connected to the first needle cylinder.
