Abstract

A safety fuse (10), in particular for use in a motor vehicle, comprising:

• • a) a first contact blade (11), a second contact blade (12), and a fusion section connecting the first contact blade (11) with the second contact blade (12), and
  • b) a housing (13) enclosing the fusion section, from which at least a portion of the first contact blade (11), and at least a portion of the second contact blade 12, protrude freely.
  • wherein
  • c) a fuse element (15a, 15b) is arranged on an area of the first contact blade (11), and wherein the particularly rail-like securing element (15a, 15b) extends perpendicularly to the direction, in which the portion of the first contact blade (11) protrudes from housing (13).

Claims

1. A safety fuse comprising:

a housing;

a first contact blade, a protruding portion of the first contact blade protruding from the housing along a first direction, the protruding portion of the first contact blade including;

two lateral edges extending in the first direction; and

a linear bend arranged on one of the lateral edges, the bend extending in a second direction perpendicular to the first direction;

a second contact blade, a protruding portion of the second contact blade protruding from the housing; and

a fusion section enclosed in the housing and connecting the first contact blade and the second contact blade.

2. A fuse according to claim 1, wherein the housing includes two slit-shaped openings for the first contact blade and the second contact blade to protrude through, respectively.

4. A fuse according to claim 1, wherein:

the first contact blade includes an enclosed portion enclosed by the housing, and

the enclosed portion has no bends.

5. A fuse according to claim 1, wherein the bend includes a straight flank bent with respect to the first contact blade.

6. A fuse according to claim 1, wherein the protruding portion of the first contact blade includes an opening.

7. A fuse according to claim 1, wherein the first contact blade the second contact blade, and the fusion section are made integrally from a plate-shaped semifinished product.

8. A fuse according to claim 1, wherein the protruding portion of the second contact blade protrudes from the housing along a third direction opposite the first direction.

9. A fuse according to claim 1, wherein:

the first contact blade and the second contact blade are formed on a common plane, and

the housing protrudes relative to the common plane on both sides of the common plane and at about a same distance away from the common plane.

3. (canceled)

10. An arrangement comprising:

a bus bar; and

a plurality of fuses arranged on the bus bar, each of the fuses including;

a housing;

a first contact blade, a protruding portion of the first contact blade protruding from the housing along a first direction, the protruding portion of the first contact blade including;

two lateral edges extending in the first direction; and

a linear bend arranged on one of the lateral edges, the bend extending in a second direction perpendicular to the first direction;

a second contact blade, a protruding portion of the second contact blade protruding from the housing; and

a fusion section enclosed in the housing and connecting the first contact blade and the second contact blade.

11. An arrangement according to claim 10, wherein at least one fuse is formed integrally on the bus bar, or mounted as a separate part on the bus bar.

12. An arrangement comprising:

a base;

a fuse mounted on the base, the fuse including;

a housing;

a first contact blade, a protruding portion of the first contact blade protruding from the housing along a first direction, the protruding portion of the first contact blade including;

two lateral edges extending in the first direction; and

linear bends arranged on the lateral edges, the bends extending in a second direction perpendicular to the first direction;

a second contact blade, a protruding portion of the second contact blade protruding from the housing; and

a fusion section enclosed in the housing and connecting the first contact blade and the second contact blade,

wherein the base is arranged on the bends, and the bends are engaged with the base.

13. An arrangement according to claim 12, wherein the base is enclosed between the bends.

14. An arrangement according to claim 12, further comprising:

a screw connection fastening the first contact blade to the base.

15. An arrangement according to claim 12, further comprising:

a threaded component, the protruding portion of the first contact blade being enclosed between the base and the threaded component.

16. An arrangement according to claim 15,

wherein the base is made of plastic and includes a threaded insert, and

wherein the threaded component is mounted on the threaded insert.

17. An arrangement according to claim 16, wherein:

the threaded insert is a screw bolt, and

the threaded component is a screw nut.

18. An arrangement according to claim 12, wherein a distance between the bends approximately equals a width of the base.

19. An arrangement according to claim 16, wherein:

the threaded insert is a screw nut or an opening with an internal thread, and

the threaded component is a screw.
