Patent ID: 8368502

Claim:
A surface mount current fuse comprising: a first base ( 13 ) having a recess ( 11 a ), the first base ( 13 ) being smaller in width between a bottom surface and an upper surface at an other longitudinal end ( 12 b ) than between the bottom surface and the upper surface at one longitudinal end ( 12 a ) so as to be asymmetrical in a longitudinal direction of the first base ( 13 ); and a second base ( 14 ) having a recess ( 11 b ), the second base ( 14 ) being smaller in width between a bottom surface and an upper surface at an other longitudinal end ( 12 b ) than between the bottom surface and the upper surface at one longitudinal end ( 12 a ) so as to be asymmetrical in a longitudinal direction of the second base ( 14 ), the second base having a same shape as the first base, wherein the first base ( 13 ) and the second base ( 14 ) are combined to form a box-shaped body ( 15 ) by joining a lower surface of the second base ( 14 ) to the upper surface of the first base ( 13 ) in such a manner that the one longitudinal end ( 12 a ) of the first base ( 13 ) and the other longitudinal end ( 12 b ) of the second base ( 14 ) are in contact with each other; the recess ( 11 a ) of the first base ( 13 ) and the recess ( 11 b ) of the second base ( 14 ) form a space portion ( 16 ) in which to place an element portion ( 17 ); and when a junction boundary between the first base ( 13 ) and the second base ( 14 ) is projected on a side surface of the body ( 15 ), a borderline between the first base ( 13 ) and the second base ( 14 ) passes through a center point (C) on the side surface of the body ( 15 ).
