ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical connection, and more particularly the invention relates to a bus bar assembly which allows multiple electronic connectors to electrically connect to separate current and voltage inputs available in the bus bar assembly.
2. Brief Description of the Related Art
A bus bar assembly connects and isolates multiple current and voltage inputs to enable the bus bar to connect to multiple electronic devices with different power requirements. Known bus bar assemblies and the electrical connectors which mate with the bus bar assembly are costly to manufacture.
Generally, there are two types of electrical connectors associated with joining multiple printed circuit boards together (i.e., connecting a mother board to a daughter board). Firsi, power connectors transmit electrical energy between interconnected printed circuit boards. Second, signal connectors transmit operating signals between interconnected printed circuit boards.
SUMMARY OF THE INVENTION
It would be desirable to provide a bus bar that does not require a soldered connection for electrically connecting to the bus bar. Where a multilayer bus bar assembly is provided, it would be desirable to make electrical connections with the multiple layers of the assembly with pin contacts of equal length to reduce the number of differing sized pin contacts required for connection to the assembly.
A bus bar assembly is provided that includes a plurality of bus bars having substantially planar portions disposed in juxtaposition. Means is disposed between adjacent bus bars for electrically isolating the adjacent bus bars from each other. The portion of each of the bus bars is made from an electrically conductive material and has a region provided with at least
5
one interconnect hole extending through the bus bar and adapted to cooperatively receive a pin member. The regions of the bus bars are disposed substantially in a plane so as to permit pin members of equal lengths to be utilized for making electrical connections with the bus bars.
