Description

Technical Field

[0001] This utility model relates to the field of power amplifier technology, specifically to a power amplifier packaging housing. Background Technology

[0002] Power amplifiers are key components in electronic engineering. Their main task is to amplify weak electrical signals from signal sources to drive load devices such as speakers and antennas. As an indispensable module in electronic systems, their performance directly determines the efficiency and quality of output devices. During the manufacturing process of power amplifiers, workers integrate them into a compact housing through packaging to achieve miniaturization and integration of the circuit, thereby improving the working stability of the power amplifier.

[0003] Existing power amplifier enclosures typically consist of multiple plates fastened together with bolts and other fasteners to form a housing structure, in which the power amplifier is positioned and installed. However, due to the large number of bolts and other fasteners required, the assembly process is quite cumbersome, necessitating multiple calibrations of the bolt and bolt hole positions for fixing. Furthermore, once the enclosure is assembled, the bolt tightening process must be repeated during subsequent disassembly, inspection, and maintenance of the power amplifier, which reduces the practicality of the enclosure to some extent.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7As shown, a power amplifier enclosure includes a protective inner shell 1. A first encapsulation plate 2 is fixedly connected to one end of the protective inner shell 1, and a second encapsulation plate 9 is provided at the other end of the protective inner shell 1. A limit frame 10 is fixedly connected to the side of the second encapsulation plate 9 closest to the protective inner shell 1. Two support seats 11 are symmetrically arranged inside the protective inner shell 1. A locking block 12 is fixedly connected to the side of each support seat 11 that is away from each other. A locking groove 13 corresponding to the locking block 12 is opened on the inner wall of the protective inner shell 1, and the locking block 12 is located inside the locking groove 13. By setting the locking groove 13 and the locking block 12, the commonly used bolt and nut installation structure can be replaced, thereby simplifying the assembly process of the enclosure. The assembly difficulty of the encapsulation shell is reduced; the adjustment component 14 is set inside the limiting frame 10. By setting the adjustment component 14, the support base 11 can slide back and forth along the inner wall of the limiting frame 10, thereby driving the locking block 12 on one side of the support base 11 away from or into the locking groove 13 on the inner wall of the protective inner shell 1, which facilitates the assembly and disassembly of the encapsulation shell; the top and bottom of the protective inner shell 1 are provided with protective covers 5, and the bottom of the inner cavity of the protective inner shell 1 is provided with a positioning component 3 to facilitate the installation of the power amplifier. By setting the positioning component 3, it is easy for the staff to put the power amplifier after positioning and fixing into the interior of the protective inner shell 1, thus facilitating the installation of the power amplifier.

[0027] The positioning component 3 includes a U-shaped plate 31 disposed at the bottom of the inner cavity of the protective inner shell 1. A mounting platform 32 is provided on the top of the U-shaped plate 31. Guide blocks 33 are fixedly connected to both sides of the inner wall of the protective inner shell 1. Guide grooves 34 corresponding to the guide blocks 33 are opened on both sides of the U-shaped plate 31. The guide blocks 33 are located inside the guide grooves 34. Figure 2 , Figure 4 and Figure 5 As shown, before assembling the inner protective shell 1, the outer protective cover 5, and the second encapsulation plate 9, the operator can pull the U-shaped plate 31 out of the inner protective shell 1 as a whole. Then, the power amplifier is positioned and fixed on the mounting platform 32 by welding or bolting. The U-shaped plate 31 is then sent into the inner protective shell 1 as a whole through the guide block 33 and the guide groove 34. At this time, the U-shaped plate 31 is restricted from vertical displacement by the guide block 33 and the guide groove 34, and is also restricted from lateral displacement by the inner protective shell 1, the first encapsulation plate 2, and the second encapsulation plate 9. This achieves the positioning and installation of the power amplifier.

[0028] Both sides of the inner protective shell 1 are fixedly connected with strip-shaped protrusions 7, and both ends of the outer protective cover 5 are fixedly connected with L-shaped plates 6. The interior of each strip-shaped protrusion 7 has a limiting groove 8 corresponding to the L-shaped plate 6. The L-shaped plate 6 is located inside the limiting groove 8. Figure 2 , Figure 3 and Figure 4As shown, by setting the limiting groove 8 and the L-shaped plate 6, the vertical displacement of the protective cover 5 can be limited, and the lateral displacement of the protective cover 5 can be limited by the second encapsulation plate 9, thus realizing the positioning and installation of the protective cover 5.

[0029] The adjusting assembly 14 includes a partition 141 fixed inside the limiting frame 10. Ball screws 142 are provided on both sides of the partition 141. One end of each ball screw 142 is rotatably connected to the inner wall of the limiting frame 10, and the other end of each ball screw 142 extends into the partition 141 and is fixedly connected to a driven bevel gear 143. A drive shaft 144 is provided between the driven bevel gears 143. One end of the drive shaft 144 is fixedly connected to a driving bevel gear 145, which meshes with the driven bevel gears 143 on both sides. The other end of the drive shaft 144 extends into the outside of the second encapsulation plate 9 and is fixedly connected to a rotating disk 146. A nut block 147 is helically connected to the outer side of the ball screw 142. One side of the nut block 147 is connected to a support base 11. Figure 2 , Figure 6 and Figure 7 As shown, after the protective outer cover 5 is installed, the second encapsulation plate 9 can be placed at the opening of the protective inner shell 1 away from the first encapsulation plate 2. Then, the rotating disk 146 can drive the transmission shaft 144 and the active bevel gear 145 to rotate. The active bevel gear 145 then drives the two ball screws 142 to rotate synchronously through the driven bevel gears 143 on both sides. The ball screws 142 then drive the locking block 12 on one side of the support base 11 to enter the locking groove 13 on the inner wall of the protective inner shell 1 through the screw nut block 147. In this way, the encapsulation shell can be quickly assembled. Compared with the commonly used installation method of bolts and nuts, the assembly process of the encapsulation shell is simplified, the assembly difficulty of the encapsulation shell is reduced, and the subsequent power amplifier inspection and maintenance work is facilitated.

[0030] Multiple support feet 17 are symmetrically installed at the bottom edge of the lower protective cover 5. Anti-slip pads 18 are fixedly connected to the bottom of each support foot 17. Figure 2 As shown, by setting anti-slip pads 18, the friction between the support foot 17 and the table surface is increased, which helps to improve the placement stability of the packaging shell and can effectively prevent the packaging shell from shifting or tipping due to external forces.

[0031] Multiple heat dissipation fins 4 are symmetrically installed on the outer side of the protective inner shell 1. The heat dissipation fins 4 are located between the protective inner shell 1 and the protective outer cover 5. Figure 2 , Figure 4 and Figure 5As shown, by setting heat dissipation fins 4, the heat dissipation of the power amplifier inside the protective inner shell 1 can be facilitated. At the same time, heat dissipation fins 4 can be used as reinforcing ribs to enhance the overall support strength of the protective inner shell 1 and further improve the protection performance. It should be noted that in order to ensure the thermal conductivity of heat dissipation fins 4, heat dissipation fins 4 can be made of steel, copper or aluminum.

[0032] The first encapsulation board 2 has intermittently spaced air inlet slots 15 inside, and the second encapsulation board 9 has intermittently spaced air outlet slots 16 inside. Figure 1 , Figure 2 and Figure 4 As shown, external air enters the gap formed by the adjacent heat dissipation fins 4 through the air inlet slot 15. The air carries away the working heat of the power amplifier along the way and is discharged from the exhaust slot 16, thus preventing the working heat from accumulating excessively between the protective inner shell 1 and the protective outer cover 5 and affecting the heat dissipation efficiency.

[0033] Working principle: First, the operator can position and install the power amplifier before assembling the protective inner shell 1, the protective outer cover 5, and the second encapsulation plate 9 using the positioning component 3. Then, the protective outer cover 5 is positioned and installed using the limiting groove 8 and the L-shaped plate 6. Next, the adjusting component 14 can drive the locking block 12 on one side of the support base 11 into the locking groove 13 on the inner wall of the protective inner shell 1. This achieves quick assembly of the encapsulation shell. Compared with the commonly used bolt and nut installation method, it simplifies the assembly process of the encapsulation shell and reduces the assembly difficulty. At the same time, the heat dissipation fins 4 facilitate the dissipation of the working heat of the power amplifier inside the protective inner shell 1, preventing excessive heat accumulation between the protective inner shell 1 and the protective outer cover 5, which would affect the heat dissipation efficiency.
