Abstract
A chassis includes floating bus bars providing power and a sliding tray included in the chassis includes a power terminal and connecting fingers contacting the floating bus bars. As the sliding tray moves in a direction of motion, the connecting fingers remain in contact with the floating bus bars, providing power to components included on the sliding tray while it is repositioned. The floating bus bars are mounted inside the chassis in a direction parallel to the sliding direction of the sliding tray, and may be positioned within the chassis in a location that does not significantly impede airflow within the chassis.
Claims21
A system comprising:
- a sliding tray for retaining one or more electronic components within a server chassis, the sliding tray configured to slide in a sliding direction between a first position and a second position, the sliding tray inside the server chassis in the first position and the sliding tray at least partially outside the server chassis in the second position;
- a power terminal mechanically coupled to the sliding tray, the power terminal comprising a first conductor for coupling a high supply voltage to the one or more electronic components and a second conductor for coupling a low supply voltage to the one or more electronic components;
- a first connecting finger conductively coupled to the first conductor of the power terminal, the first connecting finger having a surface configured to contact a first bus bar, the first connecting finger conductively contacting the first bus bar while the tray is sliding from the second to the first position, and the surface making conductive contact with the first bus bar being stationary with respect to the sliding tray when the sliding tray moves along the sliding direction;
- a second connecting finger conductively coupled to the second conductor of the power terminal, the second connecting finger having a surface configured to contact a second bus bar, the second connecting finger conductively contacting the second bus while the tray is sliding from the second to the first position, and the surface making conductive contact with the second bus bar being stationary with respect to the sliding tray when the sliding tray moves along the sliding direction;
- the first bus bar, oriented parallel to the sliding direction of the tray, the first bus bar providing the high supply voltage to the first conducting finger;
- and
- the second bus bar, oriented parallel to the sliding direction of the tray, the second bus bar providing the low supply voltage to the second conducting finger.

A system comprising:
- a first bus bar coupled to a chassis and oriented parallel to a sliding direction of a sliding tray in the chassis, the first bus bar for providing a high supply voltage;
- a second bus bar coupled to the chassis and oriented parallel to the sliding direction of the sliding tray, the second bus bar for providing a low supply voltage;
- a first connecting finger coupled to the sliding tray and having a surface configured to contact the first bus bar, the first connecting finger configured to conductively contacting the first bus bar when the sliding tray moves along the sliding direction from a second to a first position, and the surface making conductive contact with the first bus bar being stationary with respect to the sliding tray when the sliding tray moves along the sliding direction;
- and
- a second connecting finger coupled to the sliding tray and having a surface configured to contact the second bus bar, the second connecting finger configured to conductively contacting the second bus bar when the sliding tray moves along the sliding direction from the second to the first position, and the surface making conductive contact with the second bus bar being stationary with respect to the sliding tray when the sliding tray moves along the sliding direction;
- wherein the first position is defined by the sliding tray being inside the server chassis and the second position is defined by the sliding tray being at least partially outside the server chassis.
