Abstract

A cover for a vehicle electrical system component, such as a pre-fuse assembly, that includes an integrated hinge and locking mechanism. The integrated hinge allows a pivoting cover portion to easily be rotated out of the way in order to give access to an underlying component (e.g., a jump post), while the integrated locking mechanism allows that same cover to be securely locked onto itself when no access is needed. The cover is not limited to a pre-fuse assembly and may be used with other vehicle electrical system components, such as a power distribution device (e.g., a power distribution box, an electrical connection box, a junction box assembly, etc.), a wire harness protector, etc.

First claim

The invention claimed is:

1. A cover for a vehicle electrical system component, comprising:
a main body portion;
a pivoting cover portion;
an integrated hinge connected between the main body portion and the pivoting cover portion; and
an integrated locking mechanism connected to the main body portion and the pivoting cover portion and including at least one post feature and at least one clamping feature, the at least one post feature extends outwardly from the main body portion or the pivoting cover portion and the at least one clamping feature extends outwardly from the other of the main body portion or the pivoting cover portion, the at least one clamping feature includes an arcuate piece and is open towards the at least one post feature, the at least one clamping feature with the arcuate piece is sized and shaped to act as a detent when the at least one clamping feature receives the at least one post feature, wherein the at least one post feature is captured within the at least one clamping feature and engages the arcuate piece when the integrated hinge is in a closed position, and the at least one post feature is released from the at least one clamping feature when the integrated hinge is in an opened position.

2. The cover of claim 1 , wherein the entire cover including the main body portion, the pivoting cover portion, the integrated hinge, and the integrated locking mechanism is a single integrally formed part made of a molded plastic material.

3. The cover of claim 1 , wherein the main body portion includes a downwardly turned flange that extends from a side of the main body portion in a generally perpendicular manner, and the integrated hinge is connected to the downwardly turned flange.

4. The cover of claim 1 , wherein the integrated hinge is a living hinge and includes a hinge section that is designed to flex when the integrated hinge is moved between closed and opened positions.

5. The cover of claim 4 , wherein the hinge section is a thinner hinge section and the integrated hinge further includes a first thicker hinge section connected to the main body portion, a second thicker hinge section connected to the pivoting cover portion, and the thinner hinge section connected between the first and second thicker hinge sections, and the thinner hinge section has a lesser thickness than that of the first and second thicker hinge sections so that the thinner hinge section is designed to flex when the integrated hinge is moved between closed and opened positions.

6. The cover of claim 5 , wherein the first thicker hinge section is an elongated section integrally formed with and connected to the main body portion along its length, the second thicker hinge section is an elongated section integrally formed with and connected to the pivoting cover portion along its length, and the thinner hinge section is an elongated section integrally formed with and connected to both the first and second thicker hinge sections.

7. The cover of claim 1 , wherein the at least one post feature includes a cylindrical extension that extends in a generally horizontal manner and is sized and shaped to be received within the at least one clamping feature when the integrated hinge is in a closed position.

8. The cover of claim 1 , wherein the at least one post feature includes a first post feature extending from a first side surface of the pivoting cover portion and a second post feature extending from a second side surface of the pivoting cover portion.

9. The cover of claim 1 , wherein the arcuate piece is either a lower arcuate piece or an upper arcuate piece and the at least one clamping feature further includes a structural mount extending from the main body portion, the lower arcuate piece is supported by the structural mount and opens towards the at least one post feature, and the upper arcuate piece is supported by the structural mount and opens towards the at least one post feature, wherein the lower or upper arcuate piece is configured as the detent to retain the at least one post feature when the integrated hinge is in a closed position.

10. The cover of claim 9 , wherein the lower or upper arcuate piece includes a front edge with a bull nose configured to allow an outer cylindrical surface of the at least one post feature to slide along and slightly deflect the lower or upper arcuate piece out of the way until the at least one post feature clears the bull nose and settles within a recessed pocket on an inner facing surface of the lower or upper arcuate piece.

11. The cover of claim 10 , wherein the lower and upper arcuate pieces are laterally offset from one another.

12. The cover of claim 1 , wherein the at least one clamping feature includes a first clamping feature attached to a downwardly turned flange of the main body portion and a second clamping feature attached to the downwardly turned flange of the main body portion.

13. The cover of claim 1 , further comprising an additional integrated hinge extending along an edge of the cover and pivotally connecting the cover to a housing.

14. The cover of claim 1 , wherein the cover is part of a pre-fuse assembly, and the pivoting cover portion is configured to shield a horizontal jump post extending from the pre-fuse assembly.

15. The cover of claim 14 , wherein the pivoting cover portion includes a top surface, a pair of side surfaces, and an end surface that together form a boxlike formation configured to fit over and shield the horizontal jump post extending from the pre-fuse assembly, and the at least one post feature extends from one of the pair of side surfaces.

16. The cover of claim 1 , wherein the cover is part of a power distribution device, and the pivoting cover portion is configured to shield a wire harness or other connector.
