SUMMARY OF THE INVENTION It is therefore an objective of the present invention to solve the above problem and to provide a fuse assembly, in which a pluraity of members constituting a housing of the fuse assembly can be mounted tightly and whether the fuse element has blown out or not can be easily checked.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a fuse assembly according to a preferred embodiment of the present invention;
FIG. 4 is a sectional view taken along IV�IV line in FIG. 1;
DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following, a preferred embodiment of the present invention will be explained with reference to FIGS. 1 to 6. As shown in FIGS. 1 to 4, a fuse assembly 1 according to the preferred embodiment of the present invention has a pair of terminals 2 provided in parallel with each other, a fuse element 5 for connecting a pair of the terminals 2 with each other, and a housing 4 of the fuse assembly 1 for receiving ends 3 a of the terminals 2 and the fuse element 5.
The hole 62 is formed from the inner surface 17 of the body wall 14. The hole 62 penetrates through the body wall 14. The hole 62 is formed in a round shape of its plan view having an inner diameter, which is about the same with an inner diameter of the mounting hole 7. The hole 62 is situated in the vicinity of the opposite side wall 13 a and near to the end wall 12 b. When a pair of the terminals 2 is received in the housing 4, the hole 62 is symmetrically disposed in relation with the second projection 23 with respect to the axial line P. The hole 62 aligns with the mounting hole 7 of the opposite terminal 2.
The hole 63 is fromed from the inner surface 17 of the body wall 14. The hole 63 penetrates through the body wall 14. The hole 63 is formed in a round shape of its plan view having an inner diameter, which is about the same with an inner diameter of the through hole 45. The hole 63 is situated in the vicinity of the one side wall 13 b and near to the end wall 12 a. When a pair of the terminals 2 is received in the housing 4, the hole 63 is symmetrically disposed in relation with the second projection 46 with respect to the axial line P. The hole 63 aligns with the opposite through hole 45 out of a pair of the through holes 45 of the fuse element 5.
When the locking claw 61 protrudes toward the outside of the casing member 4 a, the locking claw 61 is bent toward the bottom of the locking recess 64 and engages with the locking recess 64. That is, the locking claw 61 engages with the outer surface 12 c of the housing 4, that is, the outer surface 12 c of the casing member 4 a. The locking claw 61 has a wide part 71 and a narrow part 72. When the locking claw 61 engages with the locking recess 64, the wide part 71 and the narrow part 72 continue with each other along a direction, in which the casing members 4 a and 4 b put the ends 3 a of the terminals 2 and the fuse element 5 therebetween. The wide part 71 and the narrow part 72 are formed in a rectangular shape.
When the locking claw 61 is bent toward the bottom of the locking recess 64, the wide part 71 and the narrow part 72 enter into the second wide part 65 and the second narrow part 66, respectively, thereby the locking claw 61 engages with the locking recess 64. The wide part 71 and the narrow part 72 are situated on about the same plane with that of the outer surface 12 c of the casing member 4 a. Upon the assembly of the fuse assembly 1, the first projection 23 of the one casing member 4 a is penetrated through the mounting hole 7 of the one terminal 2 and the second projection 46 is penetrated through the one through hole 45, thereby mounting the terminal 2 and the fuse element 5 to the casing member 4 a. At this time, the mounting hole 7 of the opposite terminal 2 aligns with the hole 62, while the opposite through hole 45 aligns with the hole 63.
Then, the projections 23 and 46 are welded into the holes 62 and 63, respectively, so as to fix the casing members 4 a and 4 b with each other. At this time, the locking claw 61 penetrates through the through hole 19 and protrudes toward the outside of the housing 4, that is, the outside of the casing members 4 a and 4 b. Then, one locking claw 61 is bent toward the bottom of the locking recess 64 of the one casing member 4 a, while an opposite locking claw 61 is bent toward the bottom of the locking recess 64 of the opposite casing member 4 b. Then, each locking claw 61 is engaged with the respective locking recess 64 and the fuse element 5 is fixed to the casing members 4 a and 4 b. One locking claw 61 is engaged with the locking recess 64 of the one casing member 4 a, while an opposite locking claw 61 is engaged with the locking recess 64 of the opposite casing member 4 b, thereby the casing members 4 a and 4 b are tightly fit with each other along the projections 23 and 46. That is, The casing members 4 a and 4 b are tightly fit with each other, with putting the ends 3 a of a pair of the terminals 2 and the fuse element 5 therebetween.
According to the fuse assembly 1 of the preferred embodiment, the one locking claw 61, which has protruded from the fuse element 5 toward the outside of the casing members 4 a and 4 b, engages with the locking recess 64 of the one casing member 4 a, while the opposite locking claw 61 engages with the locking recess 64 of the opposite casing member 4 b. The locking claw 61 and the locking recess 64 have the wide part 71 and the wide part 65, which engage with each other, respectively, and the narrow part 72 and the narrow part 66, which also engage with each other, respectively. The wide parts 71 and 65 continue to the narrow parts 72 and 66, respectively, along the direction, in which the casing members 4 a and 4 b put the terminals 2 and the fuse element 5 therebetween. The wide parts 71 and 65 are disposed more outside of the housing 4 than the narrow parts 72 and 66.
