Abstract
A socket connector and a card-edge is provided for electrical busses. In one embodiment, a socket is provided for electrical busses that require each end of the bus to be terminated that does not require a termination card. In another embodiment, a socket connector is provided for electrical busses that flow through several aligned socket connectors. The design of the socket connector connects a bus to termination resistors located on a circuit board of the socket connector by cross-connecting the signal through the signal pins inside the socket connector.
Claims34
An apparatus comprising:
- a circuit board;
- a plurality of termination resistors mounted on the circuit board;
- and
- a socket connector mounted on the circuit board, the socket connector being electrically coupled to the termination resistors, the socket connector having:
- a card-edge receiving area to receive a card-edge of a circuit card;
- and
- a plurality of opposing signal pins within the card-edge receiving area,
- at least some of the plurality of opposing signal pins being coupled to respective termination resistors of the plurality of termination resistors, and
- the opposing signal pins being in contact with each other when no card-edge is present in the card-edge receiving area, and
- the opposing signal pins being separated from each other when the card-edge is present in the card-edge receiving area such that the electrical coupling of the termination resistors and the socket connector is disconnected when the card-edge is inserted.
