Electrical fuse

1 . An electrical fuse comprising:

an electrical conductor element comprising a melting section and further comprising a first extension section and a second extension section both integrally formed with the melting section and extending from both ends of the melting section in the lengthwise direction thereof,

an electrically insulating, multi-part housing, which encloses said melting section in an interior space,

wherein the multi-part housing comprises a first part and a second part slidingly engaged with said first part and arranged such that the second part covers an access opening of the first part to the interior space, and

wherein the first extension section and the second extension section comprise a terminal area, respectively, both terminal areas are arranged outside the multi-part housing, and

wherein the first part comprises a first opening, the second part comprises a second opening opposite to the first opening of the first part, the first opening being directly sealingly penetrated by the first extension section, and the second opening being directly sealingly penetrated by the second extension section.

2 . The electrical fuse according to claim 1 , wherein the first extension section comprised by the electrical conductor element seals said first opening, and wherein the second extension section comprised by the electrical conductor element seals said second opening.

3 . The electrical fuse according to claim 2 , wherein a cross-section of said first extension section of the electrical conductor element perpendicular to the lengthwise direction thereof corresponds in form and dimension to the cross-section of said first opening and/or wherein the cross-section of said second extension section of the electrical conductor element perpendicular to the lengthwise direction thereof corresponds in form and dimension to the cross-section of said second opening.

4 . The electrical fuse according to claim 2 , wherein the first opening and second opening in a cross-sectional view of the multi-part housing in a plane parallel to the lengthwise direction of the melting section of the electrical conductor element are formed in a V-shape or W-shape.

5 . The electrical fuse according to claim 1 , wherein said electrical conductor element is a sheet metal.

6 . The electrical fuse according to claim 1 , further comprising a filling material filled in the interior space.

7 . The electrical fuse according to claim 6 , wherein the filling material comprises a material having arc extinction capability.

8 . The electrical fuse according to claim 6 , wherein the filling material comprises at least one of sand, silicone, glass beads and ceramic beads.

9 . A method of manufacturing an electrical fuse, said method comprising the steps:

a) providing an electrical conductor element comprising a melting section and further comprising a first extension section and a second extension section both integrally formed with the melting section and extending from both ends of the melting section in the lengthwise direction thereof,

b) providing an electrically insulating, multi-part housing comprising a first part and a second part,

c) introducing the electrical conductor element into the multi-part housing such that the melting section is enclosed in an interior space thereof,

d) slidingly engaging the first and second parts in relation to each other thus covering by the second part an access opening of the first part to the interior space,

wherein:

step b) further comprises providing the first part with a first opening and the second part with a second opening opposite to the first opening once the first part and the second part are engaged,

step c) further comprises introducing the electrical conductor element through said first opening and through said second opening such that said first opening is directly sealingly penetrated by the first extension section and the second opening is directly sealingly penetrated by the second extension section.

10 . The method according to claim 9 , further comprising the step of:

e) bending the first extension section and/or second extension section such to abut at least partially against outer wall sections of the multi-part housing.

11 . The method according to claim 9 , wherein step d) is preceded by the step of:

filling a filling material into the interior space through the access opening.
