[0025] When plugging in and replacing each power amplifier module, it is often necessary to cut off the power supply. This results in the inability to use other power amplifier modules normally after the power is cut off, and seamless switching of live plugging and unplugging cannot be achieved. In addition, each power amplifier module does not have a completely independent power supply, and there is a problem of mutual interference. Secondly, when installing and replacing, multiple bolts need to be removed to take out the power amplifier module, which is inconvenient to use.

[0026] like Figure 1-5As shown, the device includes an aluminum frame 100, and a plurality of partitions 103 are arranged inside the aluminum frame 100 to separate adjacent power amplifier module bodies 101. A plurality of backup power supply compartments 200 are installed on a mounting plate 201 fixedly connected to one side of the aluminum frame 100. Each backup power supply compartment 200 supplies power to the corresponding power amplifier module body 101, and the backup power supply compartment 200 is controlled by a power management module 102 inside the aluminum frame 100. The power management module 102 can also control the main power supply directly connected to the mounting plate 201 to realize the replacement of different partitions 103. A corresponding limit assembly 3 is arranged on the aluminum frame 100 at the bottom of each partition 103. 00 is used to fix the partition 103. The power amplifier module body 101 is powered by a backup power supply compartment 200 corresponding to one side of each power amplifier module body 101, and multiple power amplifier module bodies 101 can also be powered by a main power supply. Under the control of the power management module 102, independent power supply is achieved between the power amplifier module bodies 101 without interfering with each other, which is convenient for switching. A limiting assembly 300 is provided at the bottom of the aluminum frame 100 to fix the power amplifier module body 101. When taking out the corresponding power amplifier module body 101, the power amplifier module body 101 can be pulled out by simply pushing the limiting plate 301 to both sides. The operation is simple.

[0027] First, when installing the aluminum frame 100, place the aluminum frame 100 at a corresponding height of the server bracket, and use bolts to fix the aluminum frame 100 on the bracket to maintain the stability of the aluminum frame 100. Then, install other corresponding equipment accordingly, fix the mounting plate 201 to the back of the aluminum frame 100 using multiple fixing bolts 202, and install the backup power supply compartment 200 on the mounting plate 201 accordingly. The backup power supply compartment 200 is connected to the contacts 203 on the inner side of the mounting plate 201 through the wires inside the mounting plate 201. The contacts 203 realize the power supply to the partition 103, and the partition 103 can also realize the transmission of signals between the power management module 102.

[0028] Therefore, after the mounting plate 201 is installed, the connecting line of the main power supply is plugged into the mounting plate 201, and the corresponding signal line is plugged into the mounting plate 201 to realize signal transmission.

[0029] Furthermore, the power management module 102 is slid into the aluminum frame 100 so that the other end of the power management module 102 contacts the corresponding contact 203 on the mounting plate 201. When the power amplifier module body 101 is installed, the bottom of the power amplifier module body 101 squeezes the limiting component 300 to slide downward for a distance. The four surfaces of the power amplifier module body 101 cooperate with the multiple guide grooves provided inside the aluminum frame 100 to transport the power amplifier module body 101 toward the mounting plate 201 until the partition 103 contacts the contact 203 on the mounting plate 201. At this time, the limiting component 300 holds the power amplifier module body 101 to prevent the power amplifier module body 101 from sliding out of the aluminum frame 100 when the aluminum frame 100 shakes, and each power amplifier module body 101 is separated by the partition 103.

[0030] As described above, the limiting assembly 300 is used to limit the power amplifier module body 101, so the specific structure of the limiting assembly 300 is disclosed. The limiting assembly 300 includes limiting plates 301 on both sides. The limiting plates 301 are slidably connected to the connecting columns 305. The fixing plates 302 provided at both ends of the connecting columns 305 are fixed to the bottom of the aluminum frame 100, and the ends of the limiting plates 301 are arc-shaped. Therefore, when the power amplifier module body 101 is installed, the ends of the power amplifier module body 101 will squeeze the limiting plates 301 and slide along the top of the arc of the limiting plates 301, so that the limiting plates 301 slide downward and squeeze the elastic member 303 in the through groove, and the elastic potential energy of the elastic member 303 increases. Because the torsion springs 304 are fixedly connected to the limiting plates 301 on both sides, when the limiting plates 301 are lowered to When the bottom of the slot of the aluminum frame 100 accommodating the power amplifier module body 101 is in contact with the aluminum frame 100, the power amplifier module body 101 can just slide into the aluminum frame 100. At the same time, the torsion spring 304 bends and abuts against the connecting column 305. When the power amplifier module body 101 completely slides into the aluminum frame 100, the upper end of the limiting plate 301 is separated from the power amplifier module body 101 and pushes the limiting plate 301 upward in the opposite direction under the elastic action of the elastic member 303 and the torsion spring 304, so that the limiting plate 301 extends out of the slot to abut the power amplifier module body 101, and the limiting block 306 clamps the slot in the limiting plate 301 to prevent the sliding aluminum frame 100 from causing the power amplifier module body 101 to escape from the slot, thereby driving the limiting plate 301 to rotate, causing the power amplifier module body 101 to fall to the ground and cause damage.

[0031] Secondly, the power management module 102 is disclosed. The power management module 102 is used to manage the external power supply selection. When the main power supply is cut off, it will automatically switch to the backup power supply compartment 200 for power supply. When two power supplies are connected at the same time, the main power supply is connected by default, realizing the swappable uninterrupted power supply and seamless switching. Each power amplifier module body 101 is independently powered without interfering with each other.

[0032] In addition, when replacing the power amplifier module body 101, the limit plate 301 is pushed to both sides to make the slot in the limit plate 301 disengage from the limit block 306, and then the power amplifier module body 101 is pulled to squeeze the two limit plates 301 to make it rotate along the connecting column 305. In this process, the elastic potential energy of the torsion spring 304 increases. When the power amplifier module body 101 is separated from the aluminum frame 100, because the force generated by the torsion spring 304 when twisting is greater than the elastic potential energy accumulated by the torsion spring 304 being compressed, and the limit block 306 and the limit plate 301 The friction between them is small, so the torsion spring 304 will drive the limit plate 301 to rotate in the opposite direction until it contacts the aluminum frame 100. At the same time, sliding occurs between the limit block 306 and the limit plate 301. When the limit block 306 and the slot in the limit plate 301 cooperate with each other, the torsion spring 304 will push the limit plate 301 to move toward the limit block 306, so that the limit block 306 is stuck in the slot, and the limit block 306 contacts the limit plate 301, thereby limiting the rotation of the limit plate 301 and restoring the limit plate 301 to its original state.
