[0002] In many fields such as modern communications, electronic warfare, radar detection, and industrial control, power amplifier modules play a crucial role as core components. They can amplify weak input signals to meet the signal strength requirements of subsequent equipment or systems, ensuring the stability and reliability of signals during transmission.

[0003] However, in the existing technology, there is a lack of effective positioning mechanism at the connection between the cable connector and the power amplifier. In the actual application scenario of the power amplifier module, the connection between the cable and the module usually relies on the direct plugging of the cable connector and the module interface. Although this connection method is simple and direct, the lack of a dedicated positioning mechanism to fix the cable connector makes the connection between the cable and the power amplifier module lack sufficient stability and is easily loosened or even detached by external forces. Therefore, we need to propose a power amplifier module. Utility Model Content

[0015] 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.

[0016] Please see Figure 1-4 This utility model provides a technical solution: A power amplifier module includes: a power amplifier body 1, which has an aluminum alloy shell and integrates an RF power amplifier circuit (model: MRF157, operating frequency 800-2200MHz, output power 100W). Several sets of interfaces are provided on one side wall, and cable plugs 2 are inserted into these interfaces. These interfaces can be precisely connected to specific-specification cable plugs 2. In practical applications, different interfaces can be used to connect cables with different functions, such as signal input cables and power cables, to meet the diverse operating needs of the power amplifier module. For example, in a communication system, the signal input cable is responsible for transmitting weak signals to the power amplifier body 1 for power amplification, while the power cable provides a stable operating power supply to the power amplifier body 1. The gusseted bracket 3 is fixedly installed on one side wall of the power amplifier body 1 and located on one side of the interface. An insulating block 4 is slidably inserted into the inner cavity of the gusseted bracket 3. The insulating block 4 is fixedly sleeved on the outer wall of the cable plug 2. The inner cavity of the gusseted bracket 3 is smoothed to ensure that the insulating block 4 can be smoothly slidably inserted into it. The insulating block 4 is made of high-performance insulating material and has good electrical insulation performance and mechanical strength. It is fixedly sleeved on the outer wall of the cable plug 2, providing additional support for the cable plug 2. The locking component 5 is located at the bottom of the U-shaped frame 3, and the top of the locking component 5 passes through the U-shaped frame 3 and is inserted into the interior of the insulating block 4 to fix the insulating block 4 and the cable plug 2. The locking component 5 is a key component to ensure the stable connection of the cable plug 2.

[0017] The locking assembly 5 includes a positioning shell 501, which is fixedly connected to the bottom of the U-shaped frame 3. A locking block 502 is slidably inserted into the top of the positioning shell 501. The top of the locking block 502 passes through the U-shaped frame 3 and is inserted into the interior of the insulating block 4. A spring 503 is fixedly connected to the bottom of the locking block 502. The bottom end of the spring 503 is fixedly connected to the inner bottom of the positioning shell 501. The assembly also includes a pull rod 504, which is slidably inserted into the bottom of the positioning shell 501. The top of the pull rod 504 passes through the positioning shell 501 and is fixedly connected to the bottom of the locking block 502. This design allows the locking block 502 to automatically insert upward into the interior of the insulating block 4 under the elastic force of the spring 503, thereby fixing the insulating block 4 and the cable plug 2. When it is necessary to remove the cable plug 2, simply pull down the lever 504. The lever 504 slides into the bottom of the positioning shell 501, and its top end passes through the positioning shell 501 and is fixedly connected to the bottom of the locking block 502. The lever 504 drives the locking block 502 to move downward, compressing the spring 503, so that the locking block 502 is separated from the insulating block 4, and the cable plug 2 can be easily removed.

[0018] The top of the locking block 502 has a wedge-shaped portion 6, and the bottom of the insulating block 4 has a slot 7 that matches the wedge-shaped portion 6. The wedge-shaped portion 6 is inserted into the slot 7. The design of the wedge-shaped portion 6 allows the insulating block 4 to automatically move downward by pressing the inclined surface of the wedge-shaped portion 6 when it is inserted into the cavity of the U-shaped frame 3, thus compressing the spring 503. When the insulating block 4 is inserted into the appropriate position, the locking block 502 pops upward under the elastic force of the spring 503, and the wedge-shaped portion 6 is inserted into the slot 7 at the bottom of the insulating block 4 that matches the wedge-shaped portion 6. The engagement of the wedge-shaped part 6 and the slot 7 not only enables the rapid fixing of the insulating block 4, but also has a certain self-locking function, which can effectively prevent the insulating block 4 from easily falling off when subjected to external force. Whether in mobile communication base stations, industrial control sites or other environments where various external forces may exist, this structure can ensure the stable operation of the power amplifier body 1, avoid signal interruption or equipment failure caused by cable connection problems, and improve the reliability of the power amplifier body 1 in different application scenarios.

[0019] The power amplifier body 1 generates a lot of heat during operation. In order to ensure its normal operation, air inlets and air outlets are provided on the two side walls of the power amplifier body 1, respectively. The air inlet is equipped with a cooling assembly 8 for dissipating heat from the inside of the power amplifier body 1.

[0020] The air intake assembly 8 includes a mounting housing 801, a fan 802, and a dustproof mesh plate 803. The mounting housing 801 is fixedly embedded inside the air inlet. The fan 802 is installed inside the mounting housing 801. The dustproof mesh plate 803 is detachably installed inside the mounting housing 801 and is located on the air inlet side of the fan 802. The fan 802 is a DC12V axial flow fan. The fan 802 drives the fan blades to rotate through a motor, generating a strong airflow that draws cold air from the outside into the power amplifier body 1 to dissipate heat from the internal electronic components. The dustproof mesh plate 803 can effectively block dust, debris, and other external objects from entering the power amplifier body 1, protecting the electronic components from contamination and damage.

[0021] The inner wall of the mounting housing 801 has a slot 9 that matches the dustproof mesh plate 803, and the bottom end of the slot 9 passes through the mounting housing 801. The dustproof mesh plate 803 is inserted into the slot 9 and fixed to the mounting housing 801 with screws. This design allows the dustproof mesh plate 803 to be inserted into the slot 9 from the bottom of the mounting housing 801, achieving quick installation. At the same time, the screw fixing of the dustproof mesh plate 803 to the mounting housing 801 further enhances the installation stability of the dustproof mesh plate 803. When a lot of dust accumulates on the dustproof mesh plate 803, affecting ventilation, simply unscrew the screws and remove the dustproof mesh plate 803 from the slot 9 for cleaning or replacement; the operation is simple and convenient.

[0022] Working Principle: When connecting the cable plug 2 to the power amplifier body 1, insert the cable plug 2 into the interface on the side wall of the power amplifier body 1, and simultaneously insert the insulating block 4, which is fixedly sleeved on the outer wall of the cable plug 2, into the inner cavity of the U-shaped frame 3. During insertion, the bottom of the insulating block 4 presses against the wedge-shaped part 6 at the top of the locking block 502, causing the locking block 502 to move downward within the positioning shell 501 and compress the spring 503. When the insulating block 4 is inserted into the appropriate position, the locking block 502 pops upward under the elastic force of the spring 503, and the wedge-shaped part 6 inserts into the slot 7 at the bottom of the insulating block 4, thus fixing the insulating block 4 and the cable plug 2. At this time, the interface between the cable plug 2 and the power amplifier body 1 is stably connected, enabling reliable transmission of signals or power.

[0023] When it is necessary to disassemble the cable plug 2, pull down the lever 504. The lever 504 causes the locking block 502 to move downward, compressing the spring 503 and causing the wedge-shaped part 6 at the top of the locking block 502 to disengage from the locking groove 7 at the bottom of the insulating block 4. At this time, the insulating block 4 is no longer fixed and can be removed from the inner cavity of the bracket 3. At the same time, the cable plug 2 can also be pulled out from the interface on the side wall of the power amplifier body 1, completing the cable disassembly operation.

[0024] When the power amplifier body 1 is operating, the internal electronic components generate a significant amount of heat. The fan 802 in the air intake assembly 8 starts, driving the fan blades to rotate and generating a powerful airflow. Under the action of the fan 802, cool outside air enters the mounting housing 801 through the air inlet, passes through the dust filter 803 to remove dust and debris, and then enters the power amplifier body 1. The cool air exchanges heat with the electronic components inside the power amplifier body 1, absorbing heat and becoming hot air, which is then discharged from the air outlet. This achieves heat dissipation inside the power amplifier body 1, ensuring its operating temperature remains within the normal range and guaranteeing the performance and reliability of the power amplifier module.
