摘要： A fuse (100) includes a housing (102). A bus bar (108) extends through the housing (102). An arc interrupter (110) positioned inside the housing (102). A biasing element (112) is compressed between the housing (102) and the arc interrupter (110) to bias the arc interrupter (110) toward the bus bar (108) to separate two portions of the bus bar (108) during circuit interruption to mitigate arcing from one portion of the bus bar to the other portion of the bus bar. The bus bar (108) includes a pocket (114) defined therein wherein the bus bar (108) is of a first material, and wherein a second material is seated within the pocket (114). In another aspect, a fuse (100) includes a fuse housing (102) and a bus bar (108) extending through the housing (102). The bus bar (108) includes a pocket (114) defined therein. The bus bar (108) is of a first material, wherein a second material is seated within the pocket (114).

摘要： A thermal cutoff at least includes a current-carrying fusible element (104, 204, 312, 404, 504, 604) having two ends connected to a first electrode (107, 207, 308, 408, 508, 607) and a second electrode (108, 208, 309, 409, 509, 608), respectively. The current-carrying fusible element is provided in a closed cavity bounded by a housing (101, 201, 301, 401, 501, 601) having an opening at one end, a cover plate (102, 202, 302, 402, 502, 602), and a sealant (103, 203, 304, 403, 503, 603). The thermal cutoff further includes a first lead wire (109, 209, 310, 412, 512, 609) and a second lead wire (110, 210, 311, 413, 513, 610) each wrapped by an insulating sheath. One end of the first lead wire and one end of the second lead wire are electrically connected to the first electrode and the second electrode, respectively. The sealant is filled in the opening of the housing, at least covers an electrical joint between the first lead wire and a first electrode plate and an end of the first lead wire, and also covers an electrical joint between a second electrode plate and the second lead wire and an end of the second lead wire. The thermal cutoff exhibits excellent sealing protection performance, and is thus applicable to corresponding scenarios.

摘要： A connecting element for a secondary battery is installed on a path of current flowing through a secondary battery to electrically connect components and includes a first metal plate having a first protrusion formed to protrude at one side end thereof from the center portion of the thickness direction thereof, a second metal plate located spaced apart from the first metal plate with a gap being formed therebetween and having a second protrusion formed to protrude at one side end thereof from the center portion of the thickness direction thereof and face the first protrusion, and an alloy bridge made of alloy material having a melting point lower than those of the first metal plate and the second metal plate and formed to fill the gap. The connecting element may ensure the safety of the secondary battery in use, minimize the increase of resistance caused by applying the connecting element, and be rapidly broken even though the connecting element is applied as a part with a relatively great thickness.
