Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a communication unit fastening device that fixes the communication unit vertically to a mounting plate inside a communication device housing.

In a communication device, a large number of communication units are fixed vertically inside the case by tightening two screws at the top and bottom, but these communication units are heavy and the inside of the case is In many cases, it is fixed in a deep place, and in such cases, it takes a lot of effort to hold the communication unit, align the holes in both the mounting plate with the communication unit, maintain that state, and screw in the screws. It takes.

Therefore, in order to reduce the labor involved in installing such a communication unit, measures as shown in FIGS. 1 and 2 have been proposed.

In other words, these are the upper and lower brackets of communication unit 1) 2.2
' with bushings 3, 3', respectively, and neck screws 4, 4'.
are screwed together in advance, and a communication device housing (not shown) is attached.
A receiving bracket 7 having a semicircular notch 6 is welded to the lower mounting plate 5' of the two parallel mounting plates 5, 5' inside the unit. Fit the bushing 3' into the notch 6 of the bracket 7 to support the weight of the communication unit 1, and in this state, tighten the upper and lower neck screws 4,
4' is fastened and fixed to the mounting plates 5, 5'.

However, when the bushing 3' is fitted into the notch 6 of the holder 7, the swing of the upper part of the communication unit 1 is not restricted in any way, and even if the lower neck screw 4' is tightened to some extent, the heavy communication Since the unit 1 tends to fall down due to its own weight, there is a drawback that the alignment between the upper neck screw 4 and the tapped hole on the side of the mounting plate 5 must be performed separately.

The present invention was proposed to eliminate these drawbacks, and it allows the communication unit to be fixed vertically with a single touch so that it will not swing left or right or fall over even if the center of gravity is off the center. So that you don't have to search for etc.
The present invention provides a fastening device that has the following features.

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

3 to 5, a locking fitting 8 is provided protruding from the back side of the upper bracket 2 of the communication unit 1, and a bushing 3 is provided on the lower bracket 2' as in the case of FIGS. 1 and 2. A neck bolt 4' is screwed in advance with the bolt 4'.

As shown in detail in FIG. 5, the locking fitting 8 has one end of a vertically long rounded oval neck portion 9 integrally connected to the bracket 2, and a large-diameter head portion 10 provided at the other end. Further, an elastic rubber 11 is integrated on the neck side of the head 10.

In addition, the upper mounting plate 5 is formed with a tapered guide notch 12 at the upper end and an elongated groove 13 in the form of a vertically long cut, which has the same shape as the elongated neck portion 9 described above. There is.

Thus, when installing the communication unit, hold the communication unit 1 and fit the oval neck part 9 of the locking metal fitting 8 into the oval groove 13 from above the mounting plate 5 through the notch 12 thereof.

Then, due to the elasticity of the rubber 11, the head 1 along with the bracket 2
0 is tightly pressed against the mounting plate 5 so as not to cause play, and furthermore, the communication unit 1 is regulated by the linear part of the oval neck part 9 and the groove 13 that fit together, so that the center of gravity of the communication unit 1 is shifted from the center. It can be hung and supported vertically without tilting or swinging from side to side, even when

Also, in this state, the lower neck screw 4' will be automatically aligned with the tapped hole in the mounting plate 5', so simply tightening the neck screw 4' with a tool will mount the lower bracket 2'. It is fastened to the plate 5', and thus the communication unit 1 is integrally fixed to the mounting plates 5, 5'.

Note that instead of the rubber 11, a leaf spring or the like may be interposed between the mounting plate 5 and the head 10, and if the width of the mounting plate 5 is wide, the notch 12 for the guide can be used as the guide notch 12 for the locking metal fitting 8. It is sufficient to make a hole through which the head 10 can pass.

Further, since the position of the communication unit 1 is regulated by the locking fitting 8 not only in the vertical direction but also in the front-rear, left-right directions, a lip or the like can be used for lower fixation, which is simpler than the neck bolt 4'.

As described above, according to the present invention, the communication unit 1 is vertically suspended and supported without falling down or swinging from side to side due to the engagement between the oval neck portion 9 of the upper locking metal fitting 8 and the oval groove 13 of the mounting plate 5. Since there is no need to search for screw holes, the installation work can be performed very easily.

In addition, since the communication unit 1 is located vertically even if it is not fixed with screws, it is possible to check the arrangement of the communication unit 1 inside the communication device housing while it is temporarily fixed, or when replacing it with another one. Very convenient.
