  • Patent number: 8961245
    Abstract: A power distribution box and a method for producing a PDB include molding a lower cover with an integrated protector plate such that a unitary structure is formed. A busbar is inserted into a bottom side of a frame, and a lower cover is attached to the frame from the bottom side, thereby capturing the busbar between the frame and the lower cover. Integrating the protector plate into the lower cover eliminates a molding process, an assembly process, and adds structural integrity to the lower cover without the addition of extra structural support members, thereby reducing material use and the weight of the assembled device.

    Abstract: A fuse block 23 includes a main body portion 34, which is arranged along a top edge portion 21a of a frame 21, and an arm portion 35, which extends from an end of the main body portion 34 along a side edge portion 21b of the frame 21 that is roughly orthogonal to the top edge portion 21a. The mutual engagement of rocking restricting portions 31 and 41 that are provided on the side edge portion 21b of the frame 21 and the arm portion 35 restricts displacement of the arm portion 35 in relation to the side edge portion 21b of the frame 21 in a direction orthogonal to the length direction of the side edge portion 21b. This prevents rocking of the fuse block 23 in which the top edge portion 21a of the frame 21 serves roughly as a fulcrum.

  • Patent number: 7364438
    Abstract: A case that houses a circuit component includes a frame along a peripheral edge of a circuit board, and a cover assembled to the frame so as to cover the circuit board, and connectors, facing an outer peripheral side of the frame are provided in the frame. In corresponding surfaces of the cover and each of the connectors, a first rib, a second rib, a first rib receiving groove, and a second rib receiving groove are formed that can regulate passage of a liquid in clearances between the connectors and the cover by fitting of protrusions and recesses. This prevents or limits a liquid outside the frame from entering the frame through the clearances between the connectors and the cover.
