1. A fuse assembly comprising:
multiple fuse mounting portions formed in a housing made of resin and arranged with one another in a width direction of the fuse mounting portion, each of the fuse mounting portions having a fuse accommodating hole: and a fuse sub-assembly having a pair of male terminals and mounted to the fuse mounting portion by inserting the fuse sub-assembly into the fuse accommodating hole in a fuse-insertion direction, wherein each of the fuse mounting portions comprises; a cavity portion formed by the fuse accommodating hole and having an opening end formed at one end of the cavity portion in a height direction of the fuse mounting portion, the fuse sub-assembly being inserted into the cavity portion through the opening end, the cavity portion further having a bottom wall at the other end of the cavity portion opposing to the opening end in the fuse-insertion direction; and a pair of female terminals provided in the bottom wall of the cavity portion and arranged in a longitudinal direction of the cavity portion, each of the female terminals being electrically connected to the respective male terminals and holding the fuse sub-assembly in the cavity portion, wherein the cavity portion has a stopper portion at the bottom wall, so that the fuse sub-assembly is in contact with the stopper portion in the fuse-insertion direction in a fuse-mounted condition, wherein the cavity portion has a first pair of projecting portions at a longitudinal end of the cavity portion and a second pair of projecting portions at another longitudinal end of the cavity portion, each of the projecting portions is projecting into an inside of the cavity portion, and the projecting portions of the first pair and the projecting portions of the second pair are respectively arranged in the width direction of the cavity portion; wherein a guide surface is formed at each end of the respective projecting portion in the fuse-insertion direction and on a side closer to the opening end in order to guide the male terminals toward the female terminals when the fuse sub-assembly is inserted into the cavity portion, wherein each of a distance in the width direction between the guide surfaces formed at the first pair of the projecting portions as well as a distance in the width direction between the guide surfaces formed at the second pair of the projecting portions becomes larger in the fuse-insertion direction toward the opening end of the cavity portion, wherein a gap is formed between the fuse sub-assembly and the guide surfaces in the fuse-mounted condition in which the fuse sub-assembly is inserted into the cavity portion until the fuse sub-assembly is brought into contact with the stopper portion, and wherein the gap between the fuse sub-assembly and the guide surfaces at one of the multiple fuse mounting portions becomes larger as said fuse mounting portion is more separated from an intermediate fuse mounting portion. |
