[Problem to be solved by the invention]

Conventional power amplifiers were configured as described above, so
The high frequency section and the power supply section are housed together in the main body case 1. Therefore, the high frequency section alone cannot be compacted and stored in the rack 4, and the positions of the high frequency section and the power supply section cannot be stored together. Even if it is necessary to replace it, it is not possible,
Furthermore, during transportation, protrusions 1 to 1 from both sides of the front panel 20
There were problems such as the large part getting in the way and the large weight making it inconvenient to transport.

This invention was made to solve the above-mentioned problems, and allows the high frequency section and the power supply section to be freely combined and stored in a rack, and also allows each section to be easily carried individually. The purpose is to obtain a power amplifier that can

[Means to solve the problem]

The power amplifier according to the present invention has a power supply section and a high frequency section constituting the power amplifier separated into separate units.
Position each unit on the auxiliary panel and mount it.
Moreover, this auxiliary panel is designed to be stored in a rack.

[For production]

The power amplifier according to the present invention can be easily mounted on and removed from the auxiliary channel of the power supply section, the high frequency section, and the high frequency section. In addition, each unit can be carried around independently, and it also includes a power supply section, a high-frequency section, and a high-frequency section.3. Since the parts can be removed 1, 2 instantly and 2), maintenance is also easy. .

A mounting hole is provided at a position corresponding to the recess 18, a mounting screw 20 is inserted into the mounting hole 19, and a reference numeral 21 is a mounting screw provided at a position not corresponding to the guide recess 18 on the rear surface of the high frequency section unit 6. This is the positioning hole. Note that the guide recess 18 and the positioning hole 21 constitute a second positioning means.

One to auxiliary panel 7! 16, 22 is a bottom plate, 23 is a side plate provided substantially perpendicularly on both sides of the bottom plate 22, and 23a is a side plate 2.
3, a protrusion 10 is bent approximately perpendicularly to the left and right in front of 3; 24 is a notch for foaming provided on the protrusion 23a; 25 is a notch provided on the bottom plate 22 along the side plate 23; 11. 18 is the engaging guide rail part, 26 is the bottom plate 2
A guide 1/-rule part 27 is provided approximately in the center on the guide rail part 25 in parallel with the guide rail part 25.
6 is a screw hole into which the screw 13.20 is screwed, 28 is a stopper member provided near the rear of the guide rail portion 25.26, and 29 is a stone (member 28).
This is a guide and positioning pin provided in the positioning hole 14.21 and fitted into the positioning hole 14.21. In addition, the guide rail part 2
5.26. The stopper member 2B and the bottle 29 constitute a third positioning means that is engaged with the first or second positioning means. Further, the protruding portion 23a and the notch 24 constitute a means for attachment.

Next, the operation will be explained. When configuring a power amplifier by combining the power supply section 5 and the high frequency section unit 6, insert the power supply section unit 5 from the front of the auxiliary panel 7 L'''C1 and insert its guide recess 11 in the - direction. When the pin 29 is slid while being engaged with the guide rail portion 25 and approximately half of the guide rail portion 26, when the pin 29 is fitted into the positioning hole 14, the pin 29 comes into contact with the stopper member 28. This power supply unit 5 is positioned and mounted.Next, the high frequency unit 6 is inserted from the front of the auxiliary spring/I/7 next to the power supply unit 5, and its guide recess 18 is inserted into the other guide rail. part 25 and guide rail part 26
When the bottle 29 is slid while being engaged with the remaining half portion of the bottle 29, the bottle 29 is fitted into the positioning hole 21 and comes into contact with the stopper member 28.

As a result, the high frequency section unit 6 is positioned and mounted. Then, install screws 13.20 into holes 12.
Each unit 5.6 is fixed by screwing into the screw hole 27 through the screw hole 19.

The auxiliary panel 7 is attached to the rack 30 as shown in FIG. The power supply section unit 5 and the high frequency section unit 6 can be positioned and mounted by their respective positioning means by inserting and sliding them into the auxiliary panel 7 mounted on the rack 30 from the front thereof. Note that the rack 30 may be provided with guide means and positioning means for the auxiliary panel 7 as appropriate.

At the top of the rack 30 in FIG. 2, an auxiliary panel 7 is housed, in which a power supply unit 5 is arranged on the left side and a high frequency unit 6 is arranged on the right side. The auxiliary panel 7 has its protrusions 23a on both sides brought into contact with the front surfaces of the left and right side plates 30a of the rack 30, and is fixed by screws 31 being screwed into the notches 24 thereof.

By configuring the power source unit 5 and the high frequency unit 6 to have the same size and shape, they can be placed on the auxiliary panel 7 on either the left or the right. In FIG. 2, in the second stage of the rack 300, the high frequency section unit 6 is arranged on the left side, and the power supply section unit 5 is arranged on the right side.

Further, two high frequency unit sections 6 are arranged in the third stage of the rough 2300, and two high frequency units 6 or 10.
By using 17, it can be carried alone,
It can be used in other locations. Furthermore, the power supply unit 5 and the high frequency unit 6 can be easily attached to and removed from the rack 30 using the handles 9 and 16.

In addition, in the above embodiment, the fixing screws 13.20 of each unit 5.6 are removable, but these screws 13.2
It is also possible to use 0 as a stop type. In addition, the guide rail part 2
5.26 is provided and inserted along this, but it can also be installed without rails, so the structure of the bottom of each unit 5 and 6 does not necessarily have to be in the shape of an inverted convex shape as shown in the figure. There isn't. Furthermore, other methods may be used for fixing the rear portions of each unit 5, 6, screwing each unit 5, 6 to auxiliary panel 7, etc.
