Abstract

A power distribution system for office furniture includes a powerway having a power block with power block conductors therein. A intermediate connector block is supported on the power block and includes recesses for receiving outlet blocks having power outlets therein. The intermediate connector block may include a generally C-shaped housing which is assembled into the utility raceway between the top of the power block and the top of the utility raceway. In one embodiment powerway, cables includes woven sheaths. The woven sheaths are attached to a connector using a fastener.

Claims

1. A power distribution unit for office furniture of the type including a utility raceway, comprising:

an elongated powerway including a powerway housing adapted to be assembled horizontally within the utility raceway of an associated office furniture unit;

a plurality of powerway conductors positioned within said powerway housing;

at least one vertically accessible powerway port of the powerway in the utility raceway, said port including contacts coupled to said powerway conductors; and

an electrical connector including contacts coupled to an electrical device, said connector contacts adapted to connect with said port contacts, whereby said powerway is assembled in the utility raceway and said electrical device and said powerway housing are vertically stacked in the utility raceway such that said connector contacts are connected to said port contacts to connect said electrical device to said powerway conductors.

2. The power distribution unit as defined in claim 1, wherein said electrical device includes at least one intermediate connector block adapted to be positioned above said powerway housing in the utility raceway.

3. The power distribution unit as defined in claim 2, wherein said electrical device further includes an outlet block adapted to be assembled to said intermediate connector block, said outlet block including power outlets for said power distribution unit.

4. The power distribution unit as defined in claim 1, wherein said powerway housing includes an upwardly projecting powerway connector block including said port, said powerway connector block positioned approximately at the center of said powerway housing

5. The power distribution unit as defined in claim 4, said electrical device includes a generally C-shaped intermediate connector block, said C-shaped receptacle including a recess, said powerway connector block received in said recess of said C-shaped intermediate connector block when said intermediate connector block is positioned above said powerway housing.

6. The power distribution unit as defined in claim 1, further including an electrical connector adapted to mate with a port of a powerway associated with an adjacent panel.

7. The power distribution unit as defined in claim 6, wherein said electrical connector includes a plurality of contacts and said adjacent panel port includes a plurality of contacts, said electrical connector adapted to connect with said contacts in said port of said powerway associated with said adjacent panel.

8. The power distribution unit as defined in claim 7, further including at least two sheaths extending side-by-side in a mutually common plane between said powerway housing and said electrical connector, each of said sheaths enclosing some of said powerway conductors whereby said electrical connector is readily manipulated into connection with said part associated with said adjacent panel.

9. The power distribution unit as defined in claim 8, wherein said sheaths include woven cord.

10. The power distribution unit as defined in claim 8, wherein said at least two sheaths extend side-by-side in a horizontal plane at least at a fixed end connected to said powerway housing.

11. The power distribution system as defined in claim 8, further including a respective fastener attached over each said sheath to secure each said sheath to said electrical connector.

12. The power distribution unit as defined in claim 11 wherein each said fastener includes teeth which bite into each said sheath when each said fastener is assembled to each said sheath.

13. The power distribution unit as defined in claim 8, further including a respective fastener for each said sheath, each said fastener including:

first and second sections;

hinge means carried on said first and second sections of said fastener for providing a hinge

between said first and second sections

a first mechanical connector on one of said first and second sections;

a second mechanical connector on the other one of said first and second sections;

wherein said fastener is attached to one of said sheaths by folding said sections at said hinge means and interconnecting said first and second mechanical connectors whereby said fastener secures said sheath on said connector.

14. A power distribution unit for office furniture of the type including a utility raceway, comprising:

a powerway including a powerway housing adapted to be assembled within the utility raceway of the office furniture, said powerway housing including at least one substantially vertical face and a port in said at least one substantially vertical face;

a plurality of powerway conductors positioned within said powerway housing, said powerway conductors accessible through said port;

a intermediate connector block including a intermediate connector block housing;

a plurality of intermediate connector block conductors positioned within said intermediate connector block housing;

at least one outlet block including an outlet block housing adapted to be assembled to said intermediate connector block, said outlet block including openings; and

a plurality of outlet block conductors supported in said at least one outlet block housing, said outlet block conductors accessible through said openings, whereby said at least one outlet block provides power outlets for said power distribution unit when said powerway housing is assembled in said utility raceway and said at least one outlet block is assembled to said intermediate connector block such that said outlet block conductors are connected to said intermediate connector block conductors and said intermediate connector block is positioned above said powerway housing in the utility raceway such that said intermediate connector block conductors are connected to said powerway conductors through said port.

15. A power distribution unit for office furniture of the type including a utility raceway, comprising:

a powerway including a powerway housing adapted to be assembled within the utility raceway of an associated office furniture unit, said powerway including a plurality of conductors positioned within said powerway housing and said powerway housing including a top and at least one powerway connector block projecting upwardly from said top, said powerway conductors including contacts in said powerway connector block; and

a intermediate connector block adapted to be positioned above of said powerway housing within the utility raceway, said intermediate connector block including a generally C-shaped housing and a plurality of conductors positioned within said intermediate connector block housing, said intermediate connector block conductors including contacts adapted to mate with said powerway contacts, whereby said powerway is assembled in the utility raceway and said C-shaped housing is positioned over said powerway connector block within said utility raceway such that said intermediate connector block contacts are connected to said powerway contacts to connect said intermediate connector block conductors to said powerway conductors.
