  • Patent number: 7433195
    Abstract: The invention discloses a double-sided pluggable backplane, having one side on which one or more than one front backplane connector is disposed according to width of plot positions and the other side on which one or more than one rear backplane connector is disposed according to width of plot positions, the front backplane connector and the adjacent rear backplane connector being located at the same horizontal level on the double-sided pluggable backplane and staggered right-and-left in turn, meanwhile the front backplane connector and the rear backplane connector having uniform specifications and the same contact pin definitions. The double-sided pluggable backplane according to the present invention can realize interchangeability of front boards and rear boards and have no special requirements for design and manufacture of printed circuit boards and machining of the backplane.
