Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a portion of a shelf or the like that accommodates a large number of printed board units, on which a mating connector to be fitted with a printed board side connector is mounted.

In equipment where a large number of printed boards are mounted, if the printed boards are not fully mounted or if there are parts on the printed board side that do not require connector connection, it is necessary to also mount connectors on the equipment side at the corresponding positions. Therefore, a connector mounting window hole in which no connector is mounted is created on the connector mounting board.

If an empty window hole occurs in this way, air may leak from the empty window hole when forced air cooling is performed on the built-in printed circuit board unit.
Reduces cooling effectiveness.

To prevent this, the vacant window hole is blocked with a board and a blind cover is placed to block the air flow, but conventionally, the blind cover board is attached with screws at the top and bottom of the board. When there were many empty window holes, the workability of installing the blind cover was significantly reduced.

Further, when it becomes necessary to attach a connector to an empty window hole due to modification after the device is completed, it is inconvenient to remove the blind cover.

The present invention eliminates the above-mentioned inconvenience when attaching and detaching a blind cover to an empty window hole, and enables the blind cover to be attached and detached with a single touch.

In order to achieve this objective, the present invention provides a connector mounting board with a connector mounting window hole in which a plurality of connectors can be mounted in a row, and blocks unnecessary portions of the connector mounting window hole with a blind cover. A connector holding member is attached to the outside of the connector mounting board along one end of each connector mounting window hole, and a recess is formed by the notch formed at the edge of the connector holding member and the connector mounting board, One end of the connector is inserted and held in the recess, and the other end is screwed to a tongue piece formed at the other end of the connector mounting window hole, and a blind cover that closes the connector mounting window hole that does not require connector mounting is provided. , is formed into a rectangular shape from a flexible plate material, and one end is bent into an L-shape to fit into the four parts of the connector holding member, and is fitted into the recess, and a slit-like shape is formed on both sides of the tongue piece. The other end of the blind cover is bent into an L shape toward the printed circuit board mounting section, and the corner of the bent section is provided with a dowel that fits into the connector mounting window hole at the opposite end of the four sections. The blind plate is provided with a hole into which a tongue piece can be inserted, and the blind plate is attached to the connector mounting board by inserting the tongue piece into the hole.

Next, how the structure of the connector mounting portion according to the present invention is actually implemented will be explained using examples.

FIG. 1 is a perspective view showing an outline of the entire shelf.

There are guide rails on the top and bottom of the shelf...2...
... are arranged, and the printed board 3 ... is inserted between the upper guide rail 1 and the lower guide rail 2.

The connector mounting board 4 on the back of the shelf has connectors 5 and
...6...7...... are mounted, and printed board connectors 8...9...10 are mounted on these device side connectors. ... are fitted and connected.

Connector 5 in the upper two rows on the shelf side 5...6...
. . . are all densely arranged and fully mounted, but the lower row of connectors 7 . 11
There is...

This is because, like the printed board 3', there are only two connectors on the top two tiers and no connectors on the bottom tier, so there is also a connector 7 on the shelf side in the position corresponding to the lower tier.
This is because there is no need to implement ....

In such a case, if the empty window holes 11 are left as they are, air will leak during forced air cooling as described above, so it is necessary to cover them with a blind cover.

In the case of the figure, the upper two rows of connectors on the shelf side 5...
. . 6 . . . is covered with a back panel 12 cut out from a multilayer printed board, and the back panel 12 is used to conduct wiring between the respective connectors.

However, the lower connectors 7 are connected to other devices via the external cables 13 without being covered with a back panel.

Connector 5...6...7...
In order to implement this on the shelf side, we have adopted the following configuration.

That is, a connector holding member 14 is fixedly installed on one end side of the connector mounting window hole 11 so that a recess 15 is formed between the connector holding member 14 and the connector mounting board 4. There is.

To mount the connector, first insert one end of the connector 7 into the recess 15, then turn the other end in the direction of the arrow, and tighten only the other end with the screw 16. It is fixed to the screw hole 18 of the tongue piece 17.

As shown in FIG. 2, tongue pieces 17 and 19 are integrally formed with the mounting board 4 at both ends in the longitudinal direction of each window block 11 on which the connector is mounted, while the connector 7 has tongues 17 and 19 formed integrally with the mounting board 4, as shown in FIG. recesses 20 and 21 are formed at both ends, and when mounted, the tongue piece 17
, 19 are fitted into the recesses 20, 21 so that they are positioned relative to each other.

The above configuration consists of the upper two rows of connectors 5...6...
The same is true for ・.

FIG. 5 shows an empty window hole 11 in which a connector is not mounted.
... is a perspective view of a blind lid 22 that closes off.

The blind cover 22 is made of a highly flexible material such as a metal plate or a plastic plate, and has a rectangular shape that is about the same size or slightly thicker than the window hole 11.

Then, bent pieces 23 and 24 are formed in opposite directions at both ends.

On the one bent piece 24 side, the width of the bent piece 24 is set to the window hole 11.
The width of the tongue piece 17 is slightly smaller than the width of the tongue piece 17, and a hole 25 is formed in the bent portion to fit the tongue piece 17 in parallel.

At the end of the blind lid 22 on the other bent piece 23 side, dowels 26, 26' are formed which protrude to the side opposite to the bent piece 23.

In order to close the window hole 11 with this blind cover 22, as shown in FIG. As shown in
The other bent piece 23 side is fitted or pushed into the curved crevice 15 against the elasticity of the blind lid 22 to fit the bent piece 23 into the recessed part 15.

Further, because the dowels 26 and 26' fit into the slit-like portions 27 and 27' formed on both sides of the tongue piece 19, the bent piece 23 side of the lid plate is positioned.

The above operation involves fitting the bent piece 23 into the recess 15, bending the blind lid 22 in the same way, and inserting the other bent piece 2 into the tongue piece 17.
It may be done in the reverse order to fit the hole 25 of No. 4.

The width of the blind cover 22 is formed to be somewhat wider than the width of the window hole 11, so as shown in Fig. The situation is covered blindly.

One end of the blind lid 22 is caused by the engagement between the hole 25 and the tongue piece 17, and the other end is caused by the engagement between the bent piece 23 and the recess 15 and the engagement between the dowels 26, 26' and the slit-shaped parts 27 and 27'. By fitting, it is reliably positioned and held on the mounting board 4.

As described above, according to the present invention, the connector holding member is attached to the outside of the connector mounting board along one end of each connector mounting window hole, and the notch formed on the edge of the connector holding member is connected to the connector mounting board. One end of the connector is inserted into and held in the recess, and the other end is screwed to a tongue piece formed at the other end of the connector mounting window hole to mount the connector.

In addition, the blind cover that closes the connector mounting window hole that does not require connector mounting is formed into a strip of flexible plate material, and one end is bent into an L-shape to fit into the recess of the connector holding member. and insert the dowels into the slits on both sides of the tongue piece, bend the other end into an L-shape toward the printed circuit board mounting part, and insert the dowel into the corner of the bent part.
A hole is provided into which a tongue piece at the end opposite to the four parts of the connector mounting window hole can be inserted, and the blind cover is attached to the connector mounting board by inserting the tongue piece into the hole.

Therefore, even though the connector and the blind plate have different configurations, the connector and the blind cover can be mounted on the same connector mounting board without performing any operations on the connector mounting board.

That is, the connector is mounted by fitting one end into the recess 15 and screwing the other end to the tongue piece 17.

The blind lid is attached at one end by fitting the bent piece 23 into the recess 15 and by fitting the dowels 26.26' into the slit-shaped parts 27.27' on both sides of the tongue piece 19, and the other end is attached at the L. It can be attached by fitting the tongue piece 17 into a hole made at the corner of the letter-shaped bent part.

Moreover, even though the connector mounting board has the same configuration as the connector mounting part, the blind cover can be easily attached with one touch by curving it, and the blind cover in the mounted state can be attached to the connector mounting board. Just by pushing it out from the inside, the blind lid 22 bends into an arched shape, and the tongue piece 23 finally moves into the recess 1.
5, the operation for attaching and detaching the blind cover is simplified, and the task of attaching and detaching the blind cover is greatly improved.
