Abstract

A combination DC/data bus assembly for power converter equipment racks includes a pair of side-by-side vertical DC bus bars forming a slot between them. Extruded insulating strips carrying data bus bars are mounted in the DC bus bars so that the data bus bars face each other across the slot. Channels are formed in the front faces of the DC bus bars. A connector mounted on the power converter chassis has male DC contacts that engage the channels, and a male data contact assembly that slides into the slot to make contact with the data bus bars.

Claims

1. A combination DC and data bus assembly for stacked electrical equipment having built-in connectors, comprising:

a) a pair of elongated DC bus bars disposed vertically adjacent said equipment stack and positioned to engage said connectors as said equipment is placed into operating position in said stack;

b) a plurality of vertically extending data bus bars carried by said DC bus bars in insulated relationship thereto;

c) each of said DC bus bars having a substantially continuous channel means formed in its front face, said channel means for receiving an electrical connector therein.

2. The assembly of claim 1, in which said data bus bars are substantially longitudinally coxtensive with said DC bus bars.

3. The assembly of claim 2, in which said data bus bars are carried by an insulated strip engaged by said DC bus bar side face, said side face being undercut, and said strip engaging said undercut to prevent horizontal movement of said strip.

4. The assembly of claim 3, in which said DC bus bars and said strip are extrusions.

5. A combination DC and data bus assembly for stacked electrical equipment having built-in connectors, comprising:

a) a pair of elongated DC bus bars disposed vertically adjacent said equipment stack and positioned to engage said connectors as said equipment is placed into operating position in said stack; and

b) a plurality of vertically extending data bus bars carried by said DC bus bars in insulated relationship thereto;

c) said data bus bars being substantially longitudinally coextensive with said DC bus bars;

d) said data bus bars being carried by an insulated strip engaged by a side face of said DC bus bars, said face being undercut, and said strip engaging said undercut to prevent horizontal movement of said strip; and

e) said data bus bars being formed of conductive tape attached to said strip.

6. A combination DC and data bus assembly for stacked electrical equipment having built-in connectors, comprising:

a) a pair of elongated DC bus bars disposed vertically adjacent said equipment stack and positioned to engage said connectors as said equipment is placed into operating position in said stack; and

b) a plurality of vertically extending data bus bars carried by said DC bus bars in insulated relationship thereto;

c) each of said DC bus bars having a substantially continuous channel formed in its front face, said channel being adapted to receive a connector therein; and

d) said assembly further comprising a mounting bracket on which said DC bus bars are non-conductively mounted, said mounting bracket including a flange having a plurality of notches positioned along the length of said flange to guide a connector having a pair of male DC contacts into mating relationship with respective said bus bar channels.

7. A combination of DC and data bus assembly for stacked electrical equipment having built-in connectors, comprising:

a) a pair of elongated DC bus bars disposed vertically adjacent said equipment stack and positioned to engage said connectors as said equipment is placed into operating position in said stack;

b) said DC bus bars each having a front face, a rear face, and a side face facing a side face of the other of said DC bus bars, said side faces defining a slot between them; and

c) a plurality of vertically extending data bus bars insulated from said DC bus bars and positioned on said side faces in said slot.

8. The assembly of claim 7, in which each of said DC bus bars has a substantially continuous channel formed in said front face, said channel being adapted to receive a connector therein.

9. A connector system for connecting electrical equipment having a chassis to a combination DC and data bus when said equipment is horizontally placed into operating position in an equipment stack, comprising:

a) a connector mounted on said chassis, said connector having a pair of horizontally spaced male DC contacts and a multiple male data contact assembly;

b) a pair of elongated DC bus bars disposed vertically adjacent said equipment stack and positioned to engage said connectors as said equipment is placed into operating position in said stack;

c) said DC bus bars each having a front face, a rear face, and a side face facing a side face of the other of said DC bus bars, said side faces defining a slot between them;

d) a plurality of vertically extending data bus bars insulated from said DC bus bars and positioned on said side faces in said slot;

e) each of said DC bus bars having a substantially continuous channel formed in said front face; and

f) said male DC contacts engaging said channels and said data contact assembly engaging said slot to thereby connect such data contact assembly to said data bus bars.

10. The system of claim 9, in which said data contact assembly includes a plurality of data contacts mutually arranged such that none of them can bridge adjacent said data bus bars while said data contact assembly is engaging said slot.

11. The assembly of claim 9 further comprising a mounting bracket on which said DC bus bars are non-conductively mounted, said mounting bracket including a flange have a plurality of notches positioned along the length of said flange to guide a connector having a pair of male dc contacts into a mating relationship with respective said bus bar channels.

12. The system of claim 11 and wherein said connector includes a guide key for mating with one of said notches and a beveled surface for initially guiding said connector into mating contact with said DC bus bars.

13. The system of claim 12 further comprising a plurality of resilient wipers formed on said connector for mating with the surface of said flange to provide an electrical ground between said chassis and said equipment stack.

14. The system of claim 9 wherein each said male DC contact includes a plurality of resilient wipers for contacting a respective said DC bus bar.
