Arrangement for supplying power from a buss bar to a circuit board

A computer, comprising:

• a computer housing;
• a power supply located within said computer housing;
• a buss bar coupled to said power supply, and having a longitudinal edge that is substantially smooth and free of conductive tabs;
• at least two conductive coil springs arranged parallel to, and separated from each other, the longitudinal edge of said buss bar being positionable adjacent to said coil springs so that the respective springs are located against said buss bar along substantially an entire length of said buss bar, with each of said coils of said springs being in contact with said buss bar;
• a backplane located within said computer housing, and having a plurality of internal planes, with at least one of said internal planes being an internal power plane, and with at least another one of said internal planes being an internal wiring plane having a plurality of conductive wirings, said backplane further having means for electrically connecting each of said springs to said internal power plane without interfering with a placement of any of said conductive wirings, so that said backplane and said buss bar are in electrical communication;
• and
• at least one circuit board attached to said backplane and being coupled to said conductive wirings.

An electrical interface arrangement, comprising:

• a buss bar having a laterally-projecting base, and a first width at a location above the base, and a second width at the base that is greater than the first width so that the base of said buss bar has a footprint that is greater in area than a footprint defined by the buss bar without the base;
• a circuit board;
• and
• at least two conductive coil springs arranged parallel to, and separated from each other and conductively coupling said buss bar to said circuit board by contacting both said buss bar and said circuit board with a plurality of electrical connection points per inch,
• wherein said conductive coil springs conductively contact said buss bar along substantially an entire length of said buss bar and at the base of said buss bar;
• wherein a longitudinal edge of said buss bar is located adjacent to and between the respective springs so that the springs are positioned against said buss bar along substantially the entire length of said buss bar, with each of said coils of said springs being in contact with said buss bar;
• and wherein when said at least two conductive coil springs are in contact with said buss bar, a portion of each of said coils of said at least two conductive coil springs will be free of direct contact with said buss bar, the respective portions facing in a same direction as the longitudinal edge faces.

An electrical interface arrangement, comprising:

• a buss bar;
• a circuit board;
• and
• at least one elongated conductive member conductively coupling said buss bar to said circuit board by contacting both said buss bar and said circuit board with a plurality of electrical connection points per inch,
• wherein said buss bar has at least one conductive channel member for receiving said at least one elongated conductive member therein;
• and
• wherein said channel member provides said buss bar with a base having a footprint that is greater in area than a footprint defined by the bussbar without the channel member.
