Abstract:
1. A fuse unit including a fuse element therein, the fuse unit comprising: a first resin body; a second resin body bendably attached to the first resin body by a hinge portion such that the second resin body is bendable around the hinge portion with respect to the first resin body in a bended state; a first opposing wall provided on the first resin body; a second opposing wall provided on the second resin body and opposing the first opposing wall, so that the hinge portion is disposed between the first opposing wall and the second opposing wall; a pair of first side walls provided on the first resin body and extending in a direction intersecting an axis of the bending of the second resin body; a pair of second side walls provided on the second resin body and extending in a direction intersecting the axis of the bending of the second resin body; a pair of lock arms provided at respective ends of the first side walls closest to the hinge portion; a pair of engaging parts, provided at the lock arms respectively, and each of which having a first inclined face; and a pair of engaged parts, provided at a side of the hinge portion in the second side walls respectively, and corresponding to the engaging parts respectively, and each of which having a second inclined face such that in the bended state the first inclined face is in surface contact with the second inclined face, wherein the first inclined face and the second inclined face are formed along a direction being substantially perpendicular to a direction of a reaction force by springback of the fuse element caused by the bending of the second resin body, wherein in the bended state, the first inclined face and the second inclined face are flush with each other such that the first inclined face is locked to the second inclined face, and wherein a majority of the first inclined face is flush with a majority of the second inclined face, and wherein the first inclined face and the second inclined face are diagonal to the pair of first side walls and the pair of second side walls.
