TERMINAL BLOCK STRUCTURE FOR DRIVING UNIT

PROBLEM TO BE SOLVED: To provide a terminal block structure for a driving unit, capable of miniaturizing a connecting portion between constituents of the driving unit. SOLUTION: In this terminal block structure 1 of the driving unit, the conductivity of a gas I in a constituent 10 of a high conductivity side is higher than the conductivity of a gas II in a constituent 20 of a low conductivity side. In this case, a pair of terminals 21, 22 position connecting portions 211, 221 on one side into the gas I of the constituent 10 of the high conductivity side, and position the other connecting portions 212, 222 into the gas II in the constituent 20 of the low conductivity side. Of the adjoining terminals 21, 22, the insulation distance A between the connecting portions 211, 221 positioned in the gas I in the constituent 10 on the high conductivity side and the insulating distance B between the connecting portions 212, 222 positioned in the gas II in the constituent 20 on the low conductivity side have the relation of A>B.
