Current-limiting fuse

A method of manufacturing a current-limiting fuse, said method comprising:

• a) providing an integrally formed electrically insulating housing with walls surrounding an interior space, with a first opening and with a second opening opposite to said first opening,
• b) providing an electrically conducting, integrally formed conductor element comprising a melting section of reduced cross-section,
• c) introducing the conductor element through said first opening or through said second opening, such that said melting section is located in the interior space, and
• d) bending said conductor element to form a first terminal area and a second terminal area outside said housing, thereby sealing said first opening by a first sealing section of said conductor element and sealing said second opening by a second sealing section of said conductor element,
• wherein said conductor element provided in step b) is a sheet metal having a protrusion embossed, wherein the sheet metal has a first bending edge delimiting said first terminal area, wherein the sheet metal has a second bending edge spaced from said protrusion by a distance allowing a tight fit of the second bending edge and the protrusion between opposite inner contours of said second opening, wherein the sheet metal includes a flat region between said second bending edge and the end opposite to the first terminal area,
• wherein the step c) of introducing the conductor element comprises feeding said flat region of the conductor element from the interior space through said first opening,
• wherein the step d) comprises establishing a third bending edge delimiting said second terminal area and then establishing a fourth bending edge in proximity to said second opening.
