PROBLEM TO BE SOLVED: To provide a fuse attachment component, preventing fatigue breakage of an internal element of a fuse caused by different thermal expansion coefficients between the fuse and the attachment component therefor. SOLUTION: Support portions 10T1 and 10T2 of a fuse attachment component 10 are respectively constituted by two stoppage arms T1 and T2. At each vertex of the stoppage arms T1 and T2, nut fixation portions 10N1 and 10N2 are provided. A space G is formed between the nut fixation portions 10N1 and 10N2 and the fuse attachment component 10. When both terminals 20T1 and 20T2 of a fuse 20 are fixed to nut fixation portions 10N1 and 10N2 by a nut N, the nut fixation portions 10N1 and 10N2 are displaced because of the existence of the formed space G, even if a load is to be imposed to the internal element of the fuse due to different thermal expansion coefficients between the fuse and the attachment component therefor. Thus, both terminals 20T1 and 20T2 of the fuse 20 are also displaced, so that no large stress is imposed to the internal element. COPYRIGHT: (C)2012,JPO&INPIT |
