Description

[Detailed Description of the Invention] FA+Technical Field of the Invention The present invention is directed to an improvement of a mounting method for removably inserting a required number of printed circuit boards into a backboard 1. about.

(1)) Background of the technology This backboard 1' is equipped with a connecting wiring bag between the main body and the cage, which is detachably inserted via a connector, and generally has a housing for housing these parts. The printed board board is fixed to the back of the board, and is removably inserted into the board via a connector. Several are installed in parallel.

Although all the printed board packages are ready for use with them inserted, it may be necessary to partially replace or replace the printed board packages while they are still in use. For example, the memory function can also be reprinted,
Another example is when a spare printed board is provided, so even if one printed board goes down, it still functions normally, but it becomes necessary to replace the downed printed board.

(C:) Prior art and problems Zorin] - When inserting the root package and the bank board, all the individual terminals are connected at the same time to the terminal row at the tip of the pattern and the 21 connector on the back board. or be configured to simultaneously release the connection.

Semiconductor active parts such as Ichiriki I-run sisters and so-called ICs receive a specified power supply 4 -C3 to reach a normal operating state (although it takes a short time, it takes a lot of time). The first su(ychi-on) and the already mentioned pudding 1

, and the signal lines of other patterns connected via back port 1' were affected, resulting in malfunction (
there was.

The above-mentioned drawbacks can no longer be overlooked in electronic equipment, especially in electronic exchanges and electronic computers whose operating functions are extremely fast and complicated.

(diObjective of the invention The present invention does not have the above-mentioned drawbacks) It proposes a one-person dressing system.
Let what I do be its l' purpose.

(In order to achieve the purpose described in e1 structure of the invention, the following points are required in the present invention:
The back port is configured to removably insert the 1-pin pudding l board pasoke → shi.The common line 4 of 1 is configured to connect the pudding I-line panokée to the circuit, and the gate circuit is used for insertion of the pudding I line panokke. To provide a cylinder board mounting system having a structure that is provided with a means that is opened only at the end position of the edge.

When inserting the Zorin l- & Vaso queso into the back port 1' (the remaining end row F is connected to the connector at the same time, it takes some time to reach the final position of the insertion edge, and this time This is the communication line connection delay time until semiconductor active components such as non-nostars and ICs become steady.

That is, the backpoint will not be activated until after this delay time has expired.
The common signal line of the board is not connected to the corresponding terminal of each printed board Panoken, so (the output of a transistor or IC that occurs without reaching a constant voltage will affect other printed boards via the signal line. It will no longer be possible to do anything.
