摘要： A sealed fuse in accordance with the present disclosure may include a tubular fuse body, a trench formed in an exterior of the fuse body, and an electrically conductive endcap that fits over an end of the fuse body and is fastened to the fuse body by an electrically conductive material having a lip portion that extends into the trench to provide a barrier that extends between the fuse body and the endcap. In an embodiment, the trench may be formed in an end face of the fuse body and may extend entirely around an opening in the end of the fuse body. In another embodiment, the trench may be formed in an outwardly-facing surface of a sidewall of the fuse body and may extend entirely around the fuse body.

摘要： Provided herein are protection devices, such as fuses, including a set of trenches or pockets for retention of solder therein. In some embodiments, a fuse includes a body including a center portion extending between a first and second end portions. The first end portion includes a first trench formed in a first end surface, and the second end portion includes a second trench formed in a second end surface. The fuse may further include a first and second endcaps surrounding respective first and second end portions. The fuse may include a fusible element disposed within a central cavity of the body, the fusible element extending between the first end surface and the second end surface. In some embodiments, solder may be disposed within the first trench and the second trench, wherein the solder is in contact with the fusible element, the first endcap, or the second endcap.

摘要： Hollow bodies and hollow body fuses are disclosed. Furthermore, methods to provide hollow bodies and hollow body fuses are disclosed. In one implementation, a hollow body includes a center portion and an end portion. An endcap may be coupled to the end portion. A cavity is formed between an inside surface of the endcap and an outer periphery of the end portion. A fusible element may be disposed within the hollow body, the fusible element may be further disposed within the cavity formed between the inside surface of the endcap and the outer periphery of the end portion, the fusible element traveling a substantially diagonal path through a center of the cavity.
