FIG. 2 is an illustration of a multiprocessor 50 according to a first embodiment of the present invention. FIG. 3 is a plan view of the multiprocessor 50 shown in FIG. 2. The multiprocessor 50 is an SMP (Symmetric Multiprocessor) of the crossbar-interconnect type. The multiprocessor 50 includes 16 motherboards 51-1 to 51-16, and is capable of processing numerous information. The multiprocessor 50 is also capable of switching connections between any two motherboards 51-n selected from the 16 motherboards 51-1 to 51-16. A server 90 comprises the multiprocessor 50 in a shelf 91 indicated by a double dashed chain line in FIG. 2.
FIG. 4 is an illustration of a structure of the first back panel 70 shown in FIG. 2. As shown magnified in FIG. 4, pins 75 aa to 75 ad of each of the plug-connectors 72 are electrically and mechanically connected to and held in through holes 70 a to 70 d formed in the first back panel 70, by soldering or press fitting. Also, pins 75 ba to 75 bd of each of the plug-connectors 74 on the opposite side to the plug-connectors 72 are electrically and mechanically connected to and held in the through holes 70 a to 70 d formed in the first back panel 70 by the same method. It should be noted that, although soldering or press fitting is employed as a method of mounting the plug-connectors 72 and 74 in the present embodiment, plug-connectors of a surface mount type are also usable as the plug-connectors 72 and 74.
75aa=75ba=75ab=75bb=75ac=75bc=75ad=75bd
(55a=64a)>(55b=64b)>(55c=64c)>(55d=64d)
Here, when the connection pins of the jack-connectors 55 and 64 have relations represented by the equation “(55 a+64 d)=(55 b+64 c)=(55 c+64 b)=(55 d+64 a)=(a particular length) ” and the wiring patterns a to d of the first back panel 70 have an equal length, connection distances between connection points 55 a′ to 55 d′ of the jack-connector 55 on the motherboard 51 and connection points 64 d′ to 64 a′ of the jack-connector 64 on the crossbar-board 60, respectively, can all be made equal. With this method and an equal-length wiring on the crossbar-board, later described with reference to FIG. 3 and FIG. 6, a plurality of the motherboards can be connected to a switching circuit 63 (101 or 102 in FIG. 6) on the crossbar-board at an equal length.
In addition, even when the above-mentioned equation “(55 a+64 d)=(55 b+64 c)=(55 c+64 b)=(55 d+64 a)=(a particular length) ” does not stand for the connection pins of the jack-connectors 55 and 64, adjusting the lengths of the wiring patterns a to d of the first back panel 70 can equalize all the connection distances between the connection points 55 a′ to 55 d′ of the jack-connector 55 on the motherboard 51 and the connection points 64 d′ to 64 a′ of the jack-connector 64 on the crossbar-board 60, respectively, resulting in the same effects.
55a=64a=(5 mm); 55b=64b=(4 mm); 55c=64c=(3.5 mm); 55d=64d=(3 mm).
Here, the above-mentioned equation “(55 a+64 d)=(55 b+64 c)=(55 c+64 b)=(55 d+64 a)=(a particular length) ” does not stand.
However, arranging the lengths of the wiring patterns a to d of the first back panel 70 as follows can equalize all the connection distances between the connection points 55 a′–55 d′ and the connection points 64 d′–64 a′.
(the length of the wiring pattern a)=(the length of the wiring pattern b)+((55a+64d)−(55b+64c))
(the length of the wiring pattern d)=(the length of the wiring pattern c)+((55d+64a)−(55c+64b))
This means that differences in the summed lengths of the corresponding connection pins of the jack-connectors are compensated by adjusting the lengths of the wiring patterns so that the connection distances between the connection points 55 a′–55 d′ and the connection points 64 d′–64 a′, respectively, can all be made equal.
This method is applicable, as follows, when the corresponding connection pins 55 a–55 d and 64 d–64 a of the jack-connectors are not actually connected yet, as shown in FIG. 4.
First, the pins 75 aa–75 ad and the pins 75 bd–75 ba are connected by the wiring patterns a–d, respectively, at a possible shortest length. Next, total connection distances including the lengths of the pins 75 aa–75 ad, the pins 75 bd–75 ba, the wiring patterns a–d, the connection pins 55 a–55 d and the connection pins 64 d–64 a, respectively, are calculated. Then, differences between the longest of the total connection distances and the other total connection distances are calculated. Finally, the differences are added to the lengths of the wiring patterns, respectively, achieving an equal-length connection on the first back panel 70.

The connection pin 460 is straight at a normal temperature. When the temperature is raised to T1, a part 462 of the connection pin 460 bends upward in the direction Z1, as shown in FIG. 36D. The first back panel 70 comprises a connection block 461 fixed at a position of the surface thereof corresponding to the connection pin 460. As shown in FIG. 36B, the connection block 461 comprises: a hole 461 a into which the connection pin 460 is inserted; and a hooked hole 461 b perpendicular to the hole 461 a.
FIG. 37 is an illustration of a crossbar board-back panel assembly 88-5, which is a fifth variation of the above-mentioned crossbar board-back panel assembly 88. The crossbar board-back panel assembly 88-5 comprises: the shelf 419; the first back panel 70 attached to a side thereof in the direction Y2; the crossbar-boards 60-1 to 60-5 connected to the first back panel 70 in the shelf 419; and the second back panel 80 attached to a side of the shelf 419 in the direction Y1 and connected to the crossbar-boards 60-1 to 60-5.
FIG. 38 is an illustration of a connection part of the crossbar-board 60 and the first back panel 70, of a crossbar board-back panel assembly 88-6, which is a sixth variation of the above-mentioned crossbar board-back panel assembly 88. The crossbar-board 60 comprises a pin 480 partly projecting from an edge thereof in the direction Y2 by a predetermined length L10. The first back panel 70 comprises a through hole 481 at a position corresponding to the pin 480.
FIG. 39 is an illustration of a connection part of the crossbar-board 60 and the first back panel 70, of a crossbar board-back panel assembly 88-7, which is a seventh variation of the above-mentioned crossbar board-back panel assembly 88. The crossbar board-back panel assembly 88-7 is also a variation of the above-mentioned crossbar board-back panel assembly 88-6 shown in FIG. 38 as the sixth variation.
FIG. 40 is an illustration of a crossbar board-back panel assembly 88-8, which is an eighth variation of the above-mentioned crossbar board-back panel assembly 88. The crossbar board-back panel assembly 88-8 comprises: the first back panel 70; the crossbar-boards 60-1 to 60-5 connected thereto; and the second back panel 80 connected to the crossbar-boards 60-1 to 60-5.
FIG. 41 is an illustration of a crossbar board-back panel assembly 88-9, which is a ninth variation of the above-mentioned crossbar board-back panel assembly 88. The crossbar board-back panel assembly 88-9 comprises: the first back panel 70; the crossbar-boards 60-1 to 60-3 connected thereto; and the second back panel 80 connected to the crossbar-boards 60-1 to 60-3.
