Abstract
A power distribution box assembly can include a power distribution box housing, a fuse block, and a plurality of eyelet terminals. The fuse block can include a stamped busbar assembly, a plurality of studs, and a housing. The stamped busbar assembly can include a main power supply portion, a plurality of fuse elements, and a plurality of terminal connecting portions coupled to the plurality of fuse elements. Each of the plurality of terminal connecting portions can: (i) extend from its respective fuse element in a terminal direction that is orthogonal to both directions that the main power supply portion and the fuse elements extend.
Claims18
A fuse block, comprising:
- a stamped busbar assembly comprising:
- a main power supply portion extending in a longitudinal direction from a first end to a second end, the main power supply portion having a rectangular shaped body with a first side edge and a second side edge opposite the first side edge, the first and second side edges extending from the first end to the second end,
- a plurality of fuse elements extending from the second side edge of the main power supply portion in a fuse direction orthogonal to the longitudinal direction, and
- a plurality of terminal connecting portions coupled to the plurality of fuse elements, each of the plurality of terminal connecting portions:
- (i) extending from its respective fuse element in a terminal direction that is orthogonal to both the longitudinal direction and the fuse direction, and (ii) defining a stud aperture;
- a plurality of studs corresponding to the plurality of terminal connecting portions, respectively, each of the plurality of studs being arranged within a corresponding stud aperture;
- and
- a housing at least partially covering the stamped busbar assembly, the housing comprising an insulative material and formed by over-molding the stamped busbar assembly and the plurality of studs, the housing including an access aperture corresponding to each of the plurality of studs and configured to receive an eyelet terminal for coupling to a respective stud and terminal connecting portion,
- wherein the main power supply portion defines a power input aperture configured to receive a power distribution box stud,
- wherein the housing comprises a first portion over-molding at least one first stud of the plurality of studs and a second portion over-molding at least one second stud of the plurality of studs, the first portion and the second portion being arranged in a linear shape in an initial configuration and the first portion and the second portion being arranged to form an L-shape in a final configuration, and
- wherein the housing further comprises an index feature associated with at least one particular access aperture and associated particular terminal connecting portion, wherein the index feature inhibits coupling of the eyelet terminal with the particular terminal connecting portion when the eyelet terminal lacks a corresponding index mating feature.
