Connector system for mating multiple variant circuit cards with a fixed circuit board
View Patent ↗A system for coupling a variety of circuit cards to a circuit board, each circuit card having a respective function, the system comprising: a sequence of connectors mounted on the circuit board, each connector in the sequence of connectors having a respective function; and, one or more connectors mounted on a circuit card for mating with respective ones of the sequence of connectors mounted on the circuit board to thereby couple the circuit card to the circuit board, the respective function of the circuit card determining which ones of the sequence of connectors mounted on the circuit board that the one or more connectors mounted on the circuit card mates with; whereby space on the circuit card opposite ones of the sequence of connectors mounted on the circuit board that the one or more connectors mounted on the circuit card do not mate with is available for mounting components.
1. A circuit board adapted for mating with a plurality of circuit cards, each of the plurality of circuit cards including a plurality of electrical connectors having grouped functions, at least two of the plurality of circuit cards having different arrangements of the electrical connectors having grouped functions, the circuit board comprising:
a plurality of groups of electrical connectors adapted for mating with electrical connectors of at least one of the plurality of circuit cards, each of the plurality of groups of electrical connectors including at least a first function connector electrically connected to a first function electrical signal line and a second function connector electrically connected to a second function electrical signal line, wherein
the first function of each group of electrical connectors is the same,
the second function each group of electrical connectors is the same,
the first function is different from the second function,
every function electrical signal line is a separate and discrete electrical signal lines from every other function electrical signal line such that no two function electrical signal lines share a common bus, and
the plurality of groups of electrical connectors are suitable for mating with each distinct arrangement of the electrical connections on the plurality of circuit cards while maintaining electrical signal connectivity of the first function and the second function.
2. The circuit board of claim 1 , wherein each of the plurality of groups of electrical connectors further comprises a third function connector electrically connected to a third function electrical signal line, the third function of each of the plurality of groups of electrical connectors is the same, and the third function is different than both the first function and the second function.
3. The circuit board of claim 2 , wherein the first function is a power delivery function, the second function is a data traffic function, and the third function is a control function.
