Abstract

An electric junction box assembly includes a case, a housing and a cover. A housing is disposed on an outer surface of the case. The housing includes a back wall and a pair of supports disposed on the back wall. The supports are spaced apart from each other and each support includes an upper support member and a lower support member spaced apart from each other so as to define an opening. The upper support member has an arcuate inner surface and the lower support member has an arcuate inner surface each having a radius greater than the opening. The cover includes an axial rod having a thickness smaller than a height of the opening and a width greater than the height of the opening, wherein a rotation of the axial rod prevents the cover from being dislodged from the opening.

First claim

The invention claimed is:

1. An electric junction box assembly configured to house an element, the electric junction box assembly comprising:
a case having a first wall bounding a space for holding a plurality of electric components;
a housing disposed on an outer surface of the first wall, the element disposed within the housing, the housing including a back wall, an outer side wall, and a front wall, the housing further including a pair of supports disposed on the back wall of the housing and spaced apart from each other, each of the pair of supports includes an upper support member and a lower support member spaced apart from each other so as to define an opening, the upper support member has an arcuate inner surface and the lower support member has an arcuate inner surface each having a radius greater than the opening; and
a cover having an axial rod, the axial rod includes a pair of intermediate portions, the pair of intermediate portions have a thickness which is smaller than a height of the opening and a width which is greater than the height of the opening, wherein a rotation of the axial rod prevents the cover from being dislodged from the opening.

2. The electric junction box assembly as set forth in claim 1 , wherein the upper support member and the lower support member are offset from each other along a width of the housing.

3. The electric junction box assembly as set forth in claim 1 , wherein the axial rod includes a pair of peripheral stops and a pair of inner stops, wherein each of the pair of intermediate portions is disposed between a corresponding one of the pair of peripheral stops and the pair of inner stops.

4. The electric junction box assembly as set forth in claim 3 , wherein each of the pair of intermediate portions includes a pair of guides spaced apart from each other and opposite of each other.

5. The electric junction box assembly as set forth in claim 4 , wherein each of the pair of guides are arcuate and have a radius generally equal to a radius of the arcuate inner surface of the upper support member and the lower support member.

6. The electric junction box assembly as set forth in claim 1 , wherein the case includes a resilient stop disposed on the first wall and adjacent the back wall of the housing.

7. The electric junction box assembly as set forth in claim 6 , wherein a distal end of the resilient stop extends beyond the first wall so as to limit a rotation of the cover.

8. The electric junction box assembly as set forth in claim 7 , wherein the resilient stop includes a cam surface, the cam surface is angled outwardly with respect to the first wall.

9. The electric junction box assembly as set forth in claim 1 , further including a rib disposed on the first wall, the rib having a dimension configured to engage a peripheral edge of the cover.

10. An electric junction box assembly configured to house a jump start bolt, the electric junction box assembly comprising:
an upper case having a first wall bounding a space for holding electric components;
a jump start housing disposed on an outer surface of the first wall, the jump start bolt disposed within the jump start housing, the jump start housing including a back wall, an outer side wall, and a front wall, the jump start housing further including a pair of supports disposed on the back wall of the jump start housing and spaced apart from each other, each of the pair of supports includes an upper support member and a lower support member spaced apart from each other so as to define an opening, the upper support member has an arcuate inner surface and the lower support member has an arcuate inner surface each having a radius greater than the opening; and
a cover having an axial rod, the axial rod includes a pair of intermediate portions, a top surface and a bottom surface of the pair of intermediate portions define a thickness which is smaller than a height of the opening and the pair of intermediate portions have a width which is greater than the height of the opening, wherein a rotation of the axial rod prevents the cover from being fitted within the opening.

11. The electric junction box assembly as set forth in claim 10 , wherein the axial rod includes a pair of peripheral stops and a pair of inner stops, wherein each of the pair of intermediate portions is disposed between a corresponding one of the pair of peripheral stops and the pair of inner stops.

12. The electric junction box assembly as set forth in claim 10 , further including a rib disposed on the first wall, the rib having a dimension configured to engage a peripheral edge of the cover.

13. The electric junction box assembly as set forth in claim 10 , wherein the upper support member and the lower support member are offset from each other along a width of the housing.

14. The electric junction box assembly as set forth in claim 10 , wherein the opening is offset between 5 and 15 degrees from a plane taken along a length and width of the jump start housing.

15. The electric junction box assembly as set forth in claim 10 , wherein each of the pair of intermediate portions includes a pair of guides spaced apart from each other and opposite of each other.

16. The electric junction box assembly as set forth in claim 15 , wherein each of the pair of guides are arcuate and have a radius generally equal to a radius of the arcuate inner surface of the upper support member and the lower support member.

17. The electric junction box assembly as set forth in claim 10 , wherein the upper case includes a resilient stop disposed on the first wall and adjacent the back wall of the housing.

18. The electric junction box assembly as set forth in claim 17 , wherein a distal end of the resilient stop extends beyond the first wall so as to limit a rotation of the cover.

19. The electric junction box assembly as set forth in claim 17 , wherein the resilient stop includes a cam surface, the cam surface is angled outwardly with respect to the first wall.

20. The electric junction box assembly as set forth in claim 19 , wherein the cam surface is tapers from a distal end to a proximal end.
