Description

[Detailed Description of the Invention] The present invention relates to a mechanism for inserting and fixing a blank plate to be attached to a blank unit portion of an electronic/communication device or the like.

・、、、。 For example, a unit 2. mounted on a communication equipment rack 1 as shown in the front view of FIG. In each system block unit consisting of a predetermined number of units, or in a predetermined unit unit, an empty space 2' where no unit is mounted may be provided in order to cope with an increase in the number of units. An empty space 2' is created in the unused portion compared to the standard configuration.

As shown in the perspective view of the main part of FIG. 2, the unit mounting part 2 or empty space part 2' as described above is arranged between frames 11, 12, and 13 which are passed in the front, back, top, and bottom left and right directions, facing each other vertically. Guide groove members 14 and 15 having guides R16 and 17 provided in the front and rear unit insertion directions, and connectors 18 are installed at the rear ends of these groove members 14 and 15.

For example, the printed circuit board as a unit has the guide groove 1
6. Insert the connector 17 by fitting its upper and lower edges along the connector 18, and make a plug-in connection with the connector 18. A front plate for attaching operating parts or display parts is attached to the front surface of the connector 17 to make the front surface smooth and easy to operate. Ru.

On the other hand, in the above-mentioned empty space 2', there is simply an insertion plate 19 corresponding to a printed circuit board as shown in FIG. A so-called empty plate 21 to which a face plate 20 is attached is inserted into the state shown by the imaginary wire number in FIG. 2, and the empty space portion is smoothed in front view.

This empty plate 21 is used to insert the insertion plate 19 along the guide grooves 16 and 17, but it does not need to be long enough to contact the connector 18, and it is sufficient to simply support the front plate 20, however, when the unit is inserted. It needs to be supported so that it cannot be easily pulled out and does not wobble until it is removed or removed for other reasons.

Therefore, in the past, holes were made from the upper and lower sides of the insertion plate 19, a rivet-shaped plastic pin 23 was inserted into the hole 22, and the height of the pin 23 was made approximately equal to the width of the grooves 16 and 17 by heat caulking. It was then pushed in and supported in the state shown in Figure 4.

In such a conventional empty plate insertion support mechanism, if the pin is not thermally caulked appropriately for the groove width, it may not be able to be inserted or may be easily pulled out, which is troublesome and costly. Ta.

The present invention solves the above-mentioned problems.

Embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 5 is a perspective view of an embodiment of the empty plate insertion and fixing mechanism of the present invention, and the width in the vertical direction is such that it can be inserted into the guide grooves 16 and 17 provided vertically opposite to each other in FIG. and an upper end edge 26 of the insertion plate 24, on which a front plate 25 is attached in a T-shape in plan view.
A substantially L-shaped cut 27 is formed in the hole 27, and the inner end of this cut 27 is a round hole 28. Due to the cut 27, a tongue piece 29 parallel to the end surface 26 has a narrow width with respect to the end surface 26 at the round hole 28. Summer (Figure 6).

Note that the open end of the L-shaped cut 27 is on the front plate 25 side, and the closed end, ie, the round hole 28, is on the rear 30 side.

The insertion plate 24 is made of an elastic metal plate, and the tongue piece 29
As shown in Figure 5, the front plate 25 is centered around the round hole 28.
The direction is bent and raised 29', and the insertion plate 2 is inserted from the tip 29'.
4 to the lower edge 31 is larger than the width between the guide grooves 16 and 17.

When the empty plate 32 configured as described above is inserted into the empty space 2' of the frame, the tongue piece 29 is inclined so that the front plate 25 side is higher.
As the tongue piece 29 is inserted, the tongue piece 29 is smoothly inserted into the groove while elastically deforming downward, and is elastically slid and inserted into the bottom surface of the guide groove.

A side view of the fully inserted state is shown in FIG.
2 is held between the guide grooves 16 and 17 by the elastic force of the tongue piece 29 and will not be easily pulled out.In particular, the inclined direction of the tongue piece 29 is designed to facilitate insertion and resist the pull-out direction. This is convenient.

Note that if the corners are rounded like 29'' in FIG. 6, the guide groove will not be damaged during insertion or withdrawal.

If the blank plate 32 is to be pulled out for convenience or as needed, it can be easily pulled out by pulling with a force greater than the above-mentioned resistance force.

A plurality of fixing mechanisms of the present invention may be provided on one end surface depending on the size of the empty plate, or an appropriate number may be provided on both end surfaces that contact the guide groove, and the shape of the insertion plate may also be reinforced. The inner surface may be hollowed out, etc., and may be made of synthetic resin instead of being limited to a metal plate.

Further, the opposing direction of the guide grooves is not limited to the vertical direction, but may be horizontal.

As explained above, the empty plate insertion and fixing mechanism according to the present invention can be easily inserted and securely retained by forming the bent inclined tongue piece on the end surface of the insertion plate that is inserted into the guide groove. Moreover, since no special additional parts 9 or the like are required, complexity is eliminated, and the cost can be reduced due to simplicity, which has great practical effects.
