[22] In the conventional technology as described above, the insulator and the cover interposed to insulate the output terminal have a disadvantage in that the tightening force of the nut fastening the output terminal is weakened in the process of repeating contraction and expansion due to high heat.
[23] In addition, the tightening force is weakened as described above, and the current is not supplied smoothly due to the poor contact between the nuts (N1, N2) and the terminal (TM), and the current is repeatedly supplied and interrupted, thereby damaging the electrical equipment. Has a problem that causes.
[24] In particular, the use of chromium-plated space to solve this problem is causing environmental problems, there are a number of problems such as having to go through the post-processing process for forming the groove to improve the assembly and mounting of the cover.
[25] Accordingly, the present invention provides a new type of spacer which can be interposed between the cathode heat sink and the cover of the rectifier as the invention in order to solve the problems as described above. It aims to contribute to improving the quality and performance of AC generators by making them smooth.
