Abstract

A power distribution assembly is disclosed having a bussing distribution connector having a plurality of electrical bussing terminals positioned within an electrically insulative housing. A plurality of electrical terminals are positioned in the housing for distributing more than one electrical circuit; at least one ground terminal, at least one neutral terminal and at least three hot terminals. A grounding shell at least partially surrounds the bussing connector and includes a grounding tab grounding the one ground terminal to the metallic grounding shell. In another embodiment, two bussing connectors are interconnected together, to provide for an increased number of output ports.

Claims

1. A power distribution unit comprising:

bussing connection means having insulating housing means having side walls and end walls, where at least one of said end walls comprises through ports and where said member comprises a plurality of internal side-by-side channels, each said channel being in communication with at least two of said through ports, at least one of said side walls including an opening therethrough in communication with one of said channels;

a plurality of electrical power busses positioned in said channels, said busses comprising at least one ground bus, one neutral bus and one hot bus, said ground bus being aligned with said opening in said one channel, said busses being positioned in a stacked array and each comprising a generally flat strip and at least two electrical terminals extending from ends of said busses and insulatively positioned in said at least two through ports for further distribution of power, wherein at least one edge of said ground bus comprises a contact portion folded over about said strip, thereby forming a receptacle portion between said folded over contact and said strip;

metallic grounding shell means at least partially surrounding said housing, leaving said through ports exposed, said metallic grounding shell means comprising a slot therethrough aligned with said opening and said ground terminal; and

a grounding tab positioned through said slot and electrically connected to said ground bus and electrically secured to said metallic grounding shell, thereby grounding said ground terminal to said metallic grounding shell means.

2. The power distribution unit of claim 1, wherein said grounding receptacle is positioned facing said opening in said housing means for receipt therein of said grounding tab.

3. A power distribution unit comprising:

bussing connection means having insulating housing means having side walls and end walls, where at least one of said end walls comprises through ports and where said member comprises a plurality of internal side-by-side channels, each said channel being in communication with at least two of said through ports, at least one of said side walls including an opening therethrough in communication with one of said channels;

a plurality of electrical power busses positioned in said channels, said busses comprising at least one ground bus, one neutral bus and one hot bus, said ground bus being aligned with said opening in said one channel, said busses being positioned in a stacked array and each comprising a generally flat strip and at least two electrical terminals extending from ends of said busses and insulatively positioned in said at least two through ports for further distribution of power, wherein said power busses include two integral contacts extending from said flat strips and positioned in said through ports;

a metallic grounding shell means at least partially surrounding said housing, leaving said through ports exposed, said metallic grounding shell means comprising a slot therethrough aligned with said opening and said ground terminal; and

a grounding tab positioned through said slot and electrically connected to said ground bus and electrically secured to said metallic grounding shell, thereby grounding said ground terminal to said metallic grounding shell means.

4. The electrical connector of claim 3, wherein each said through port includes one of said two integral contacts from each said power bus.

5. The electrical connector of claim 4, wherein said ports are arranged for mateable interconnecting with an electrical connector, where one electrical connector is provided for input of electrical power and one electrical connector is provided for redistribution of electrical power.

6. The electrical connector of claim 3, wherein said bussing interconnection means comprises two discrete insulative housings, where each said housing has electrical power busses positioned in respective channels, and each said bus within a first insulative housing is electrically connected with an associated bus in a second insulative housing.

7. The electrical connector of claim 6, wherein said power busses are interconnected by commoning said associated busses through said through ports.

8. The power distribution unit of claim 6, wherein each said housing includes a plurality of openings in communication with respective channels and power busses, and said busses in said first insulative housing are interconnected to said busses in said second insulative housing by way of conductive tabs inserted in associated openings of the two said housings.

9. An electrical power distribution assembly comprising:

first and second modular bussing connectors, each bussing connector having insulative support housings and electrical bus terminals positioned therein, comprised of at least one ground bus terminal, one neutral bus terminal and one hot bus terminal, to complete one electrical power circuit, said at least one ground bus terminal being electrically connected to a generally flat strip folded over to form a receptacle terminal, said bussing connectors having a plurality of ports for the access of the bussing terminals for the input or output of a power source, said ports defining an electrical connection access for a mateable connector, said bussing terminals being positioned in said insulative support housing with terminal portions adjacent to each said connection access;

commoning means for interconnecting said bussing terminals together, to increase the number of output ports;

grounding means surrounding said first and second modular bussing connectors; and

means for commoning said at least one ground bus terminal to said grounding means comprising a grounding tab electrically connected to said folded over receptacle terminal of said at least one ground bus terminal through one of the access ports and electrically secured to the grounding means.

10. The power distribution assembly of claim 9, wherein said commoning means comprises an electrical cable interconnecting one of said access ports on said first bussing connector to one of said access ports on said second terminals.

11. The power distribution assembly of claim 9, wherein each of said bussing connectors include recesses in a front face thereof, with access openings into said bussing terminals.

12. The power distribution assembly of claim 11, wherein said commoning means comprises a jumper connector positioned at least part way in each said recess, where said jumper connector comprises electrical terminals adapted for receipt with said access openings in said first and second bussing connectors.

13. The power distribution assembly of claim 12 wherein said jumper connector comprises a plurality of wafers stacked one above the other, with said electrical terminals positioned therebetween.

14. The power distribution assembly of claim 9 wherein said grounding means comprises a stamped sheet metal cover substantially enclosing said first and second bussing connectors.

15. An electrical power distribution assembly comprising:

first and second modular bussing connectors, each bussing connector having insulative support housings and electrical bus terminals positioned therein, comprised of at least one ground bus terminal, one neutral terminal and one hot bus terminal, to complete one electrical power circuit, said bussing connectors having a plurality of first ports for the access of the bussing terminals for the input or output of a power source, said ports defining an electrical connection access for a mateable connector, said bussing terminals being positioned in said insulative support housing with terminal portions adjacent to each said connection access, said bussing connectors further comprising a set of second access ports intersecting said bussing terminals;
