Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a wiring board support device that is disposed within a case and is used when a housed wiring board is removed from the case and checked.

For example, a plurality of wiring boards may be stacked and arranged in a case.

In that case, open the upper wiring board, take it out of the case, and check the lower wiring board inside the case.
It is necessary to electrically connect the upper wiring board and the removed wiring board.

For this reason, in the past, as shown in FIG. It was designed to be electrically connected to the wiring board housed in the .

In this way, the cable 13 is used so that even if the wiring board 12 is taken out of the case 11, it is still connected to the inside of the case. 11, the cable 13 becomes a hindrance.

Also, such an unnecessarily long cable, that is, case 1
1, there is no need to use such a long cable, and if such a long cable is used, there is a risk of introducing noise, and it is not necessary to use such a long cable. This also had the disadvantages of not looking good, requiring a large storage space, and reducing margin due to signal delays.

The object of this invention is to provide a wiring board support device that allows the wiring board to be easily removed from the case and inspected inside without requiring a particularly long cable.

For example, as shown in FIGS. 2 and 3, a wiring board 12 is housed in a case or frame 11 so as to be removable.

The wiring board 12 is removably attached to, for example, a main board 14 housed in the case 11,
It performs the required operations in cooperation with the main board 14.

The main board 14 and the wiring board 12 are electrically connected to each other through a cable 15.

In this embodiment, a supporting member 16 is provided so that one side of the wiring board 12 can be attached to one side wall of the frame 11 substantially along the same and substantially parallel to the wall surface.

That is, the supporting member 16 has two holding pieces 17 and 18 facing each other with an interval slightly larger than the thickness of the side wall of the frame, and one end thereof is fixed to the wiring board 12.

One side wall edge of the frame 11 can be supported by the clamping pieces 17 and 18.

In this example, two such clamping tools 16 are attached to the cable 1 connected to the main board 14 with an appropriate distance between them.
It is attached to the side of No. 5 near the lead-out portion of the wiring board 12, slightly protruding from the board and substantially parallel thereto.

Therefore, for example, as shown in FIG.
By sandwiching the upper part of one side wall of the frame, the wiring board 12 is held vertically to that side wall of the frame, and is maintained connected to the main board 14 by the cable 15.

In this way, the wiring board 12 can be taken out from the frame 11, and the wiring board 12 can be removed from the frame 11 instead of being placed at a distance from the frame 11.
By selecting the side wall close to the connection point between the cable 15 and the main board 14, the length of the cable 15 can be adjusted so that the wiring board 12 can be supported within the frame 11. The length of the cable 15 need only be very slightly longer than that required when the cable is housed in the cable, and depending on the case, the length may be the same, so there is no need to make the cable 15 longer.

Furthermore, the lower main board 14 can be inspected while the wiring board 12 and main board 14 are connected.

Since the cable 15 is not long, there is no need to enlarge the space of the frame 11, the appearance is good, there is less risk of introducing electrically induced noise, and there is less delay in signal transmission.

The clamping tool 16 can be used not only for supporting the side wall of the frame 11, but also for example, as shown in FIG. Alternatively, the wiring board 12 may be held vertically by holding the side edge of the wiring board 12 between the supporting member 16 and the side wall.

Further, the side wall of the frame 11 is not limited to the outer side wall, but if there is a partition wall separating the inside of the frame 11, the wiring board may be similarly held by the partition wall.

Note that the wiring board 12 may be used as the main board alone without being attached to the main board 14, or in addition to this, various types of wiring board 12 may be used.

Therefore, it is conceivable that the wiring board 12 is rotatably fixed to the frame 11, for example, by a hinge, but in that case, it would be inconvenient to replace the wiring board 12.

However, according to the wiring board support device of this invention, the wiring board 1
2 can be easily replaced.
