Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a panel connection device that is applied as a package mounting structure for information processing devices and various other electronic devices.

[Conventional technology]

Conventionally, this type of panel connection device includes a back panel having a signal pattern for connection between multiple rows of card slots, and a plurality of cards connected by pins to the card slots in each row of this back panel. There is a device that transmits signals from the card to other cards via the back panel.

[Problem that the invention attempts to solve]

When making a bus connection in such a panel connection device, it is necessary to arrange a signal pattern for the bus connection on the back panel in advance, and as the number of bus types increases, the number of signals on the card increases accordingly. I needed to.

However, in this case, there is a limit to the number of card pins that can be connected, so a signal pattern was formed on the back panel so that a specific bus could be used within a specific range.

FIG. 3 shows an example of such a back panel. That is, the back panel 1 is provided with a plurality of rows of card slots 2a...2f, and signal patterns 3a, 3b, 3c... are formed.
For example, the bus A uses the card slots 2a to 2c, so it is connected using the signal pattern 3a. Also, bus B has card slots 2d and 2.
Connect with signal pattern 3b for use with e.

In such a configuration, if you try to connect a card that requires a bus connection with a certain function due to an option, etc., if the slot for that option is determined in advance, you can handle all cases. All buses must be connected with consideration, and the disadvantage is that the card lacks pins in that case. Another disadvantage is that an extra card slot for options corresponding to each bus must be provided.

The present invention was devised in view of these circumstances, and provides a panel connection device that can increase the number of bus connections regardless of the limit on the number of card pins and can minimize the number of optional card slots required. The purpose is to

[Means for solving problems]

The panel connection device of the present invention includes a back panel having a plurality of rows of card slots and a signal pattern for connection between the card slots, and a plurality of cards connected by pins to the card slots in each row of the back panel. The device is characterized by a sub-back panel that can be connected to pins protruding on the side opposite to the card connection side of the back panel and changes the form of signal connection from the back panel to the card, and by using this sub-back panel, the number of bus connections can be increased. At the same time, there is no need to provide an extra card slot for options, thereby achieving the above-mentioned object.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 and 2. The back panel used is of the same construction as the conventional one shown in FIG. That is, in this embodiment as well, the third
As shown in the figure, the back panel 1 has a plurality of rows of card slots 2a...2f and signal patterns 3a, 3b, 3c... for connecting the card slots.
It has...

FIG. 1 shows the combination of cards and sub-back panels to this back panel 1. As shown in FIG. That is, the pins 5 of the connectors 4a...4f are inserted into the card slots 2a...2f of the back panel 1, respectively, so that the connectors 4a...4f are attached to the back panel 1. Then, the card 6a is connected to each connector 4a...4f.
...6f are connected to each other.

The sub-back panel 7 has, for example, two rows of slots 8a, 8b arranged at intervals, and the pins 1 of the sub-connectors 9a, 9b are inserted into the slots 8a, 8b.
0 is connected. Note that the slots 8a and 8b of this sub-back panel 7 correspond to the two card slots 2a, . . . , 2f of the back panel 1, which span two rows. In other words, the connector 9 connected to the slots 8a and 8b of the sub-panel 7
a and 9b can be connected to pins 5 protruding from the card slot 2c in the fourth row from the right end of the back panel 3 and the card slot 2f in the right end row, for example.

FIG. 2 shows the back side of the sub-back panel 7, and signal patterns 11a, 11b, . . . are formed to connect the slots 8a, 8b in each row.

Next, the action will be explained.

As shown in FIGS. 1 and 3, the wiring area of bus A includes cards 6a to 4c of connectors 4a to 4c.
Similarly, the wiring area of bus B is used as a connection bus between connectors 4d and 4e. In addition, the card slot 2f is
This is a slot for selecting a specific bus as an option and connecting a signal to the card 6f via the connector 4f. Therefore, the signal from the bus A wiring area is transferred to card slot 1 for connector 4f.
When connecting to card f, as described above, connect the pins 5 protruding from the card slots 2c, 2f of the back panel 1 to the slots 8a, 8 of the sub-back panel 7.
Connect the connectors 9a and 9b connected to b. Then, the signal pattern 1 on the sub-back panel 7
A signal from the wiring area of bus A is transmitted to card slot 2d via 1a, 11b, . . . , and connection to card 6f on back panel 1 is made.

In addition, the signal of the bus B wiring area is connected to the card 6f.
When connecting to the card slot 2d and card 6f, which are not shown, the bus B wiring is connected.
What is necessary is to provide a sub-back panel connectable to the card slot 2f corresponding to the card slot 2f.

Furthermore, when connecting a plurality of bus wires, it is sufficient to provide a sub-back panel having slots at corresponding positions.

According to the embodiment with the above configuration, by providing the sub-back panel 7, the cards 6a, . . . , 6f
The number of bus connections can be increased without the need to increase the number of pins, and an optional card slot 2f for the back panel 1, for example, is sufficient.

[Effect of idea]

As described above, by providing a sub-back panel, the present invention can increase the number of bus connections without the need to increase the number of pins, whereas previously only limited bus connections could be made due to the limited number of pins. At the same time, the number of optional card slots that should be provided for each bus to be used can be minimized.
