Abstract: A reduced height relay block for use within a power distribution device for a vehicle electrical system. In one embodiment, there is provided a power distribution device that routes or distributes power throughout a vehicle electrical system and includes a lower housing, a relay block assembly, a module with a printed circuit board (PCB), an array of serviceable electrical components, and an upper cover. The relay block assembly includes a relay block with an upper side that is generally planar and includes a number of cavities for receiving the serviceable electrical components. An underside of the upper cover includes clearance ribs specifically designed to oppose certain serviceable electrical components and prevent them from backing out of their respective cavities.

Abstract: A wrap around bus bar that provides battery power (also referred to as B+ power) to components within a power distribution device for a vehicle electrical system, such as a hybrid-type power distribution box (PDB). The power distribution device routes or distributes power throughout a vehicle electrical system and may include a lower cover, a wrap around bus bar, a relay block assembly, a module with a printed circuit board (PCB), an array of relays and fuses, and an upper cover. Battery power is provided from a vehicle battery and/or alternator to a terminal connection, from the terminal connection to the wrap around bus bar, and from the wrap around bus bar to the relay block assembly, the module and potentially other components within the power distribution device.

Abstract: A terminal connection assembly that provides battery power (also referred to as B+ power) to one more bus bar(s) in a power distribution device that is part of a vehicle electrical system, such as a power distribution box (PDB). The terminal connection assembly may include a post, a cylinder, annular contacts, and a retention feature and the terminal connection assembly is designed to improve the ease with which the power distribution device is assembled and/or serviced.

Abstract: A fuse header includes a housing with cavities and terminals mounted in the housing adjacent the cavities. Fuses can be mounted removably in the cavities so that the fuses connect to the terminals in the respective cavity. Ends of the terminals opposite the fuses have widths that are narrowed substantially and may equal the thickness of the terminals. The narrow widths impede a flow of heat from the fuse to large conductive regions on a circuit board that could function as a heat sink. Thus, the fuses will provide more reliable protection for components downstream of the fuses.

Abstract: A fuse and relay block assembly (10) for an automotive vehicle includes a lower cover (12) and an upper cover (60) mounted in substantially opposed relationship to one another. A relay block (70) is mounted between the lower cover (12) and the upper cover (60) and can receive electrical devices (R, F) mounted along a mounting direction (MD). A relay module assembly (80) is mounted between the lower cover (12) and the upper cover (60) and can receive electrical devices (R, F) mounted along a transverse direction (TD) substantially perpendicular to the mounting direction (MD). Thus, a greater density of electrical devices (R, F) can be mounted within a smaller footprint.
