An electronic module is an electronic module for a vehicle, including a casing that has a through hole in communication with the inside and the outside of the casing and a bus bar includes a strip-shaped connection terminal to be fitted into a connector of a fuse, the connection terminal includes one end portion in its longitudinal direction exposed to the outside of the casing. The casing has a first flat surface in a peripheral edge portion of the insertion hole, on the inner side of the casing, the connection terminal includes an extension portion that is located on another end side in the longitudinal direction with respect to the one end portion and extends in a width direction of the connection terminal, and the extension portion has a second flat surface that comes into contact with the first flat surface from the inner side of the casing.

The solution of the present disclosure connects the power in parallel distribution chains. A horizontal pizza box in the middle of the equipment stack represents the power box (PB), which houses the power modules (PMs), such as the power input modules (PIMs) or the power supply units (PSUs). The PMs in the PB are connected to the office power source(s), and the PB supplies power to the parallel distribution chains (A and B). The parallel distribution chains are composed of jumper segments that are based on busbar-like technology, with each jumper segment being the length of the distance between coupled boxes. Any box can be removed without disrupting either distribution chain. Advantageously, the jumper segments are touch-proof, from a safety perspective. Thus, instead of a jumper created using a cable, PCB, etc., or a jumper composed of a custom molded back-to-back connector, the jumpers are based on busbar-like technology.
