Backplane and communication apparatus
View Patent ↗The present invention discloses a communication apparatus. The communication apparatus includes one or more board and a backplane. The board includes a connector and a function processing unit circuit connected to the connector. The backplane includes at least one group of board connectors. Each group of the board connectors includes two board connectors that receive signals from different boards. The board connector includes connection terminals connected to the connector on boards. The two board connectors are distributed up and down, and the connection terminals of the two board connectors are distributed symmetrically around a center. The foregoing communication apparatus and backplane are cost-efficient.
1. A backplane comprising:
at least one group of board connectors, wherein
each group of the board connectors comprises two board connectors that receive signals from different boards; and
each of the board connectors comprises connection terminals connected to a connector on a board, the two board connectors are distributed in one board slot and adjacent to each other, and the connection terminals of the two board connectors are distributed symmetrically around a center.
2. The backplane according to claim 1 , wherein after one board connector is connected to the connector on the board and the board is rotated by 180 degrees around an axis through the center and perpendicular to the plane of the board connector, the connector on the board can be connected to another board connector of the backplane.
3. The backplane according to claim 1 , wherein the center is the intersection point between a first perpendicular line and a second perpendicular line, where the first perpendicular line is the central line of inserting the board onto the backplane vertically, and the second perpendicular line is the central line of the two board connectors.
4. The backplane according to claim 1 , wherein the backplane further comprises one or more components of anti-misoperation sockets, panel labels, and indicators, and said components are distributed symmetrically around the center.
5. The backplane according to claim 1 , wherein the board slot has left trough and right trough, which are centered on the center symmetrically.
6. A communication apparatus comprising:
one or more board and a backplane, wherein
each of the one or more board comprises a connector and a function processing unit circuit connected to the connector;
the backplane comprises at least one group of board connectors;
each group of the board connectors comprises two board connectors that receive signals from different boards, each of the board connectors comprises connection terminals connected to another connector on the one or more board, the two board connectors are distributed in one board slot adjacent to each other, and the connection terminals of the two board connectors are distributed symmetrically around a center.
7. The communication apparatus according to claim 6 , wherein after one board connector is connected to the another connector on each of the one or more board and each of the one or more board is rotated by 180 degrees around an axis through the center and perpendicular to the plane of the board connector, the connector on the board can be connected to another board connector of the backplane.
8. The communication apparatus according to claim 6 , wherein the center is the intersection point between a first perpendicular line and a second perpendicular line, where the first perpendicular line is the central line of inserting the board onto the backplane vertically, and the second perpendicular line is the central line of the two board connectors.
9. The communication apparatus according to claim 6 , wherein the backplane further comprises one or more components of anti-misoperation sockets, panel labels, and indicators, and said components are distributed symmetrically around the center.
10. The communication apparatus according to claim 6 , wherein the each board slot has left and right trough, which are centered on the center symmetrically.
