た。Since the conventional spring hooking device is constructed as described above, it is forbidden to contact the live part when the spring comes off as in the US UL standard. In this case, if one side comes off, the other easily comes off, so it is necessary to provide some kind of stopper. For example, by making the end of the spring hook 1 larger than the inner diameter of the hook 3a of the tension spring 3, It was necessary to make the hook part 3b slightly press-fit at the time of insertion, or to deform the shape of the hook part 3b with a pliers after the spring was applied to eliminate the gap 5.
