Abstract

A wraparound bus bar (14) that provides battery power (also referred to as B+ power) to components within a power distribution device (10) for a vehicle electrical system, such as a hybrid power distribution box (PDB). The power distribution unit carries or distributes power throughout the vehicle electrical system and may include a lower cover (12), wraparound bus bars (14), relay block assemblies (16), modules with printed circuit boards (PCBs) ( 18), array of relays and fuses (20) and upper cover (22). Battery power is provided from the vehicle battery and / or alternator to the terminal connections (72), from the terminal connections to the wraparound busbars, and from the wraparound busbars into the relay block assembly, modules, and power distribution devices other possible components.

Description

technical field [0001] The present invention relates generally to power distribution devices for vehicle electrical systems, and more particularly to bus bars within power distribution devices. Background technique [0002] Various types of power distribution devices are used in vehicle electrical systems, some of which are referred to as distribution boxes, electrical junction boxes, electrical junction boxes, power centers, and the like. The power distribution unit distributes low-voltage battery power to various accessories and devices in the vehicle's electrical system. In many power distribution unit designs, conductive metal strips or strips, often called bus bars, are used to provide battery power to components within the power distribution unit. The total amount of current or amperage that can be handled by a particular bus bar depends on its material composition as well as the size and configuration of the bus bar (eg, the cross-sectional area of ​​the bus bar affe...
