1. A turbo compressor that compresses a gas by rotating an impeller with an electric motor, the compressor comprising:a housing accommodating the electric motor; anda plurality of connection terminals mounted to the housing, each of the plurality of connection terminals having a first end portion arranged inside of the housing, and a second end portion arranged outside of the housing, whereina lead wire of the electric motor can be affixed to the first end portion,the housing has a plurality of mounting holes, each of the plurality of connection terminals passing through a respective one of the plurality of mounting holes,each of the plurality of mounting holes is formed to a size that allows insertion and removal of the first end portion together with the lead wire,each of the plurality of connection terminals has a respective flange portion that surrounds a respective one of the plurality of mounting holes, andeach of the respective flange portions can be mounted to the housing from outside of the housing, without involving rotation of the connection terminal. 2. A turbo refrigerator comprising: a condenser that liquefies a compressed refrigerant;an evaporator that cools a cooling object by evaporating the refrigerant that is liquefied by the condenser; anda turbo compressor that compresses the refrigerant that is evaporated by the evaporator and supplies it to the condenser, whereinthe turbo compressor is the turbo compressor according to claim 1. 3. The turbo compressor according to claim 1, further comprising an orientation adjusting member that adjusts the orientation of the connection terminal with respect to the mounting hole to a predetermined orientation. 4. The turbo compressor according to claim 3, wherein the orientation adjusting member has a mark that is formed on the flange portion corresponding to the orientation in which the lead wire is affixed to the first end portion. 5. The turbo compressor according to claim 1, wherein the flange portion can be attached to the housing by fixing members, andthe fixing members are provided in a non-equal interval in the circumferential direction of the flange portion. 6. The turbo compressor according to claim 1, wherein the lead wire has a crimp terminal that is mounted to the connection terminal,a portion of the crimp terminal projects from the connection terminal in the mounted state, andthe flange portion has a mark that is formed corresponding to a direction in which the crimp terminal projects. 7. The turbo compressor according to claim 1, wherein each of the mounting holes has an oblong shape. 8. The turbo compressor according to claim 7, wherein the lead wire has a crimp terminal that is mounted to the connection terminal,a portion of the crimp terminal projects from the connection terminal in the mounted state, anda long-axis direction of the mounting hole matches a direction in which the crimp terminal projects. 9. The turbo compressor according to claim 8, wherein the flange portion has a mark that is formed corresponding to the direction in which the crimp terminal projects.
