[0002] In fields such as wireless communication and radar detection, the RF power amplifier module is a core component, and its performance and stability directly affect the working effect of the entire system.

[0003] With the continuous development of technology, the requirements for the integration, power density and heat dissipation efficiency of RF power amplifier modules are increasing. Traditional RF power amplifier connection structures mostly use bolt fastening, welding and other methods for connection. The installation process is cumbersome, requires professional tools and high operating skills, and the installation and disassembly time is long, which is not conducive to the rapid deployment and maintenance of equipment.

[0004] In terms of heat dissipation, traditional air-cooling methods have limited efficiency and cannot meet the heat dissipation requirements of high-power-density RF power amplifier modules, resulting in excessively high module operating temperatures, performance degradation, or even damage.

[0005] In addition, traditional connection structures are also insufficient in terms of electrical connection reliability and anti-interference performance, and are easily affected by external electromagnetic interference, which affects signal transmission quality. To solve the above problems, it is of great practical significance to develop a modular RF power amplifier connection structure with fast connection, efficient heat dissipation and stable electrical performance.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a modular radio frequency power amplifier quick connection structure, including a mounting panel 1. Positioning holes 2 are provided at the two rear corners of the top surface of the mounting panel 1. The openings of the holes are chamfered. Two sliding grooves 3 are provided on the mounting panel 1. The sliding grooves 3 are T-shaped grooves. Limiting blocks 4 are provided at both ends of the sliding grooves 3. Sliding sliders 5 are slidably connected to the sliding grooves 3. The sliding sliders 5 are T-shaped sliders 5, which cooperate with the sliding grooves 3. A module 6 is fixedly connected to the sliding slider 5. Pin holes 7 are provided on both sides of the module 6. Positioning pins 8 are slidably connected to the pin holes 7. After the module 6 moves to the designated position, the positioning pins 8 pass through the pin holes 7 and enter the positioning holes 2.

[0030] Side plates 9 are fixedly connected to both sides of module 6. Threaded holes 10 are provided on the side plates 9. Locking bolts 11 are threaded into the threaded holes 10. After module 6 is moved to the designated position, it is locked by pressing the locking bolts 11 against the side of the mounting panel 1.

[0031] Module 6 is equipped with a heat sink 12. The surface of the heat sink 12 is anodized to improve heat dissipation efficiency. Thermal grease 13 is provided at the contact position between the bottom of module 6 and the mounting panel 1 to ensure that the bottom of module 6 is in contact with the top surface of the mounting panel 1.

[0032] Two parallel water-cooling pipes 14 are opened inside the mounting panel 1. The two ends of the water-cooling pipes 14 extend to the edge of the panel and are threaded through tapping to connect quick-connect fittings. The quick-connect fittings and the channel interface are sealed with thread sealant to ensure that there is no leakage of coolant.

[0033] A socket 15 is fixedly connected to the mounting panel 1. The socket 15 is located slightly behind the center of the top surface of the mounting panel 1. A U-shaped shield 16 is welded around the socket 15. The bottom of the shield 16 is attached to the top surface of the mounting panel 1, and electrical connection is achieved by conductive adhesive.

[0034] At the center of the rear face of module 6, a multi-contact flexible pin connector 17 is fixedly installed at the position corresponding to the socket 15 on the mounting panel 1. The pins of the flexible pin connector 17 are connected to the inside of module 6. The inside of module 6 is a circuit board 19, which integrates various circuits for the operation of the device.

[0035] A status indicator light 18 is fixedly connected to the center of the front end of module 6. The status indicator light 18 is a red and green dual-color light and is covered by a transparent protective cap. The light socket is connected to the internal circuit of module 6 by wires. The wires are fixed through the internal wire groove of module 6 to avoid interference with other components. It can display the working status of module 6. A solid green light indicates that module 6 is working normally, a flashing red light indicates a connection abnormality, and a solid red light indicates a fault in module 6, which makes it easy for operators to quickly locate the problem.

[0036] Working principle: During installation, the operator holds module 6 and aligns the T-shaped slider 5 at the bottom of module 6 with the T-shaped groove 3 on the mounting panel 1, and pushes module 6 along the direction of the groove 3. During the sliding process, the positioning pins 8 on both sides move synchronously with module 6. When module 6 moves to the designated position, the positioning pins 8 are exactly aligned with the positioning holes 2 at the two rear corners of the top surface of the mounting panel 1. Under the action of gravity or slight external force, the positioning pins 8 pass through the pin holes 7 on module 6 and insert into the positioning holes 2, completing the initial positioning and ensuring the positional accuracy of module 6 on the mounting panel 1.

[0037] At this time, the operator rotates the locking bolt 11 on the side plate 9 of module 6, so that the end of the locking bolt 11 gradually presses against the side of the mounting panel 1. As the bolt is tightened, the friction generated further fixes module 6, preventing it from shifting due to external forces such as vibration and impact during operation, thus achieving a stable mechanical connection. When module 6 is working, it generates a lot of heat. The heat is first transferred to the bottom of module 6. Since the bottom of module 6 is coated with thermal grease 13 at the contact position with the mounting panel 1, and the two are in close contact, the heat can be efficiently transferred from module 6 to the mounting panel 1.

[0038] The coolant continuously circulates in the two parallel water-cooling pipes 14 inside the mounting panel 1. When heat is transferred to the mounting panel 1, it is quickly absorbed by the coolant. The coolant carries away the heat and circulates to the cooling equipment through the quick-connect connector connected to the external cooling equipment for heat dissipation, thereby achieving efficient heat dissipation of the module 6 and ensuring that the module 6 works stably within a suitable temperature range.

[0039] The multi-contact flexible pin connector 17 located at the center of the rear end face of module 6 will tightly mate with the socket 15 located at the rear center of the top surface of the mounting panel 1 after module 6 is moved to the installation position and mechanically fixed. The pins of the flexible pin connector 17 are connected to various circuits integrated on the circuit board 19 inside module 6, while the socket 15 is connected to the external circuit. When the flexible pin is inserted into the socket 15, a reliable electrical connection path is formed, realizing the transmission of signals between module 6 and external devices.

[0040] Meanwhile, the U-shaped shielding cover 16 around the socket 15 works in conjunction with the shielding structure on the module 6, and is electrically connected through conductive adhesive to form a complete electromagnetic shielding space, effectively reducing the impact of electromagnetic interference on signal transmission and ensuring stable and accurate transmission of radio frequency signals.

[0041] The status indicator light 18, located at the center of the front end of module 6, has its socket connected to the internal circuitry of module 6 via wires. The wires are arranged along the internal slots of module 6 to avoid interference with other components. When module 6 is working normally, the internal circuitry outputs a specific electrical signal to keep the green light of status indicator light 18 constantly lit. If an abnormality occurs in the connection, such as poor contact between the spring pin connector 17 and the socket 15, a short circuit, or an open circuit, the internal circuitry will change the output signal, causing the red light to flash, indicating an abnormal connection.

[0042] If module 6 malfunctions, such as power device burnout or chip damage, the internal circuit will output a corresponding fault signal, causing the red light to stay on. Operators can quickly judge the working status of module 6 based on the indicator light status and perform timely maintenance and repair.

[0043] By using the sliding engagement of T-shaped slider 5 and slide groove 3, combined with the precise positioning of positioning pin 8 and positioning hole 2, operators can quickly install module 6 to the designated position without complicated alignment operations, greatly shortening the installation time. When disassembling, simply reverse the operation: first loosen the locking bolt 11, then pull out the positioning pin 8, and module 6 can be easily removed from the mounting panel 1, facilitating equipment maintenance and upgrades.

[0044] The positioning pin 8 cooperates with the positioning hole 2 to achieve initial positioning, and the locking bolt 11 presses the side of the mounting panel 1 to provide additional friction. The two work together to enable the module 6 to resist greater vibration and impact during operation, ensure the stability of the connection, reduce electrical connection failures caused by mechanical loosening, and improve the reliability of equipment operation.

[0045] The bottom of module 6 is coated with thermal grease 13 and fits tightly against the mounting panel 1. Together with the water cooling pipes 14 inside the mounting panel 1, it forms an efficient heat dissipation path. Compared with the traditional air cooling method, water cooling is more efficient and can quickly remove the heat generated by module 6, effectively reduce the operating temperature of module 6, extend the service life of module 6, and improve the overall performance of the equipment.

[0046] The tight mating of the multi-contact flexible pin connector 17 and the socket 15 ensures the reliability of the electrical connection and the stability of the signal transmission; the electromagnetic shielding system composed of the U-shaped shield 16 and the shielding structure of module 6 (if any) can effectively shield external electromagnetic interference, reduce signal distortion and attenuation, and improve the transmission quality of radio frequency signals, making it suitable for fields such as communication and radar where high signal quality is required.

[0047] The red and green dual-color status indicator lights 18 can intuitively reflect the working status of module 6. Operators can quickly determine whether module 6 is working properly without the need for additional testing equipment, promptly identify and solve problems, reduce equipment maintenance costs, and improve equipment maintainability.

[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
