Power distribution rack bus bar assembly and method of assembling the same

A power distribution rack comprising:

• a chassis defining a first slot and a second slot adjacent said first slot;
• a plurality of electronics modules including a first electronics module coupled within said first slot and a second electronics module coupled within said second slot, wherein said first and said second electronics modules are configured for insertion into respective said first and said second slots, said first electronics module including a first connector and a second connector, said second electronics module including a third connector and a fourth connector;
• a bus bar assembly coupled to said chassis, said bus bar assembly comprising:
• an outer bus bar comprising a first flange, a second flange, and a first channel defined therebetween, said outer bus bar having a first polarity;
• and
• an inner bus bar coupled within said first channel, said inner bus bar comprising a third flange and a fourth flange, wherein said first and third flanges are coupled to said first electronics module and said second and fourth flanges are coupled to said second electronics module, and said inner bus bar having a second polarity different from the first polarity, wherein said first and third flanges define a first space therebetween, and said second and fourth flanges define a second space therebetween, the first space configured to receive at least a portion of the first and second connectors, the second space configured to receive at least a portion of the third and fourth connectors.

A method of assembling a power distribution rack, said method comprising:

• providing a chassis defining a first slot and a second slot adjacent the first slot;
• inserting a first electronics module into the first slot and a second electronics module into the second slot, the first electronics module including a first connector and a second connector, the second electronics module including a third connector and a fourth connector;
• coupling a bus bar assembly to the chassis, wherein the bus bar assembly includes:
• an outer bus bar comprising a first flange, a second flange, and a first channel defined therebetween, the outer bus bar having a first polarity;
• and
• an inner bus bar coupled within the first channel, wherein the inner bus bar includes a third flange and a fourth flange, the inner bus bar having a second polarity different from the first polarity, wherein the first and third flanges define a first space therebetween, and the second and fourth flanges define a second space therebetween;
• and
• coupling the first and third flanges to the first electronics module and coupling the second and fourth flanges to the second electronics module, the first and second connectors extending at least partly in the first space, the third and fourth connectors extending at least partly in the second space.
