Fuse
Provided herein is a fuse that includes a conductive member, two shielding portions arranged on the conductive member, and a case. The conductive member includes a two bars on each end of the conductive member and an element (e.g., melting portion) that integrally connects the two bars. The two shielding members are disk shaped and are situated on the conductive member between the element and the two bars. The case encloses the element and the two shielding members.
1. A fuse comprising:
a conductive member formed integrally with a melting portion that melts and breaks when overcurrent occurs, and with first and second bars;
two shielding portions arranged on the conductive member to hold the melting portion in between, each of the two shielding portions being comprised of a single-piece shielding member where each shielding member is situated on the conductive member between the melting portion and the first and second bars, wherein each shielding member is disk shaped and includes a holder and a slot on one side of the holder where the slot is in communication with an outer side of the holder and extends to an outer circumference of its respective shielding member and a slit on an opposite side of the holder where the slit is in communication with an opposite outer side of the holder and extends toward but not to an opposite outer side of the outer circumference of its respective shielding member; and
a case formed from an electrically-insulative material, wherein the case encloses the melting portion in cooperation with the two shielding portions.
2. The fuse according to claim 1 , wherein
the holder of one of the shielding members and the conductive member holds the other one of the shielding members and the conductive member.
3. The fuse according to claim 2 , wherein
each shielding member is coupled to the conductive member by the holder by performing swaging to close portions spaced apart by the slot in a state in which the conductive member is inserted into the holder through the slot.
