The structure of claim 1, wherein said third fixing portion is located at an upper portion of said third terminal block so that said eighth, tenth and twelfth output wires each pass between said third terminal block and said fourth terminal block and are fixed to said upper portion of said third terminal block.

5. The structure for mounting an output line according to claim 1, wherein a fourth via hole is formed in a lower portion of the fourth terminal block, so that the seventh, ninth and eleventh output lines pass through the fourth via hole and are fixed to the fourth fixing portion at a bend, and the fourth fixing portion is located on a side of the fourth terminal block facing away from the third terminal block.

6. The card mounting structure of an output cord as set forth in claim 1, wherein said first terminal block, said second terminal block, said third terminal block and said fourth terminal block are each arcuate.

7. The clamping structure of an output cord according to claim 1, further comprising:

and the three external phase lines are respectively connected with the seventh output line, the ninth output line and the eleventh output line.

8. The card mounting arrangement of output wires according to claim 1, wherein said first through twelfth output wires are all flat wires.

9. The clamping structure of an output cord according to claim 1, further comprising:

the third first connecting strips are fixed between the first junction block and the third junction block, and the first output line and the eighth output line, the third output line and the tenth output line, and the fifth output line and the twelfth output line are connected through the first connecting strips;

and the second connecting strip is fixed on the second junction block and is connected with the second, fourth and sixth output lines.
