[0021] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figs. 1 to 4 As shown, this utility model embodiment provides a broadband impedance matching device structure for a radio frequency system, including a broadband impedance matching device body 1 for a radio frequency system. One end of the device body 1 is screwed with a first connector 2, and the other end of the device body 1 is screwed with a second connector 3. The second connector 3 has a limiting groove 4 on its outside and a first electric rod 5 fixedly connected inside the second connector 3. The device body 1 cooperates with different first connectors 2 and second connectors 3 to perform multi-device matching operations.

[0024] The aforementioned broadband impedance matching structure for radio frequency (RF) systems achieves compatibility and installation flexibility with various RF devices through modular design. The structure includes a broadband impedance matching unit 1, with a first connector 2 screwed to one end for connecting to an RF signal source and a second connector 3 screwed to the other end for connecting to a load. A limiting groove 4 is provided on the exterior of the second connector 3 for positioning, and a first electrode 5 is fixedly connected internally for signal transmission. Users can replace the first connector 2 and the second connector 3 according to different equipment requirements to ensure the matching unit matches the device interface. During installation, the matching unit is connected to the RF signal source via the first connector 2 and to the load via the second connector 3, secured using the limiting groove 4. The broadband matching network within the matching unit 1 provides good impedance matching over a wide frequency range, reducing signal reflection and improving transmission efficiency. RF testing equipment allows for dynamic adjustment of the matching network parameters to optimize matching performance for different frequencies or environmental conditions. This modular design not only solves the environmental requirements of traditional integrated impedance matching units during additional installations but also provides greater flexibility and adaptability to meet the broadband impedance matching needs of different RF systems.

[0025] In this embodiment, the first connector 2 includes a tube 201, with a slot inside the tube 201 and a limiting hole 204 on the inner wall of the tube 201. Two limiting holes 204 are provided, symmetrically located on both sides of the inner wall of the tube 201. Two pressing blocks 202 are also provided on the outer wall of the tube 201, each corresponding to one of the two limiting holes 204.

[0026] The first joint 2 is designed as a plug-in pipe 201 structure for connecting with a radio frequency signal source. The plug-in pipe 201 is internally provided with a plug-in slot for inserting a plug 6 to ensure stable connection. The inner wall of the plug-in pipe 201 is provided with two symmetrical limiting holes 204 located on both sides of the plug-in pipe 201 to provide additional fixing and positioning functions to prevent the plug 6 from loosening or falling off during use. Meanwhile, the outer wall of the plug-in pipe 201 is provided with two pressing blocks 202 corresponding to the limiting holes 204. The purpose of the pressing blocks 202 is to press the sliding blocks 602 on the plug 6 when needed so that the plug 6 can be easily pulled out, and when not pressed, the sliding blocks 602 enter the limiting state through the limiting holes 204 to ensure that the plug 6 will not accidentally fall off during normal use. This design not only ensures the stability of the connection, but also makes the replacement and installation of the joint more convenient, and adapts to the connection requirements of different radio frequency devices.

[0027] In this embodiment, the plug 6 is inserted and installed in the plug-in slot of the plug-in pipe 201. The plug 6 includes a plug rod 601, and the plug rod 601 is slidably installed with sliding blocks 602 on both sides through first springs 604. The plug-in pipe 201 is provided with a guide slot 203, and the sliding blocks 602 are guided to movably insert the limiting holes 204 through the guide slot 203. The sliding blocks 602 are in movable contact with the pressing blocks 202.

[0028] The design of the plug 6 makes the cooperation with the plug-in pipe 201 more delicate and firm. The plug 6 includes a plug rod 601, and the plug rod 601 is slidably installed with sliding blocks 602 on both sides through first springs 604. The sliding blocks 602 are movably inserted into the limiting holes 204 of the plug-in pipe 201 through the guidance of the guide slot 203. When the plug 6 is inserted into the plug-in pipe 201, the sliding blocks 602 will automatically pop out and be clamped into the limiting holes 204 under the action of the springs, realizing a self-locking function. This self-locking mechanism not only simplifies the installation process, but also prevents the plug 6 from accidentally falling off during use. The pressing blocks 202 and the sliding blocks 602 are designed to be in movable contact. The pressing blocks 202 are used to press the sliding blocks 602 when needed so that the plug 6 can be easily pulled out, and when not pressed, the sliding blocks 602 enter the limiting state through the limiting holes 204 to ensure that the plug 6 will not accidentally fall off during normal use. This design not only ensures efficient transmission of radio frequency signals, but also considers the convenience of device maintenance and replacement.

[0029] As preferred in the utility model, a second electric rod 603 is fixedly installed in the plug rod 601, the second electric rod 603 is electrically connected with a conductive disc 605, the conductive disc 605 is movably connected with the plug-in pipe 201, and the conductive disc 605 is slidably installed at one end of the plug rod 601 through a second spring 606.

[0030] In this embodiment, a second electric rod 603 is fixedly installed inside the plug rod 601, and the second electric rod 603 is electrically connected to a conductive disk 605. The conductive disk 605 is movably electrically connected to the insertion tube 201 and is slidably mounted on one end of the plug rod 601 via a second spring 606. The purpose of this design is to achieve radio frequency signal transmission through the contact between the conductive disk 605 and the insertion tube 201 when the plug 6 is inserted into the insertion tube 201. The function of the second spring 606 is to provide a certain degree of elasticity to the conductive disk 605, allowing it to move flexibly during the insertion and removal of the plug 6, ensuring the contact area and pressure with the insertion tube 201, thereby ensuring the stability and reliability of the electrical connection. At the same time, this design also takes into account the possible slight movement or vibration of the plug 6, ensuring that even under such circumstances, the conductive disk 605 can maintain good contact with the insertion tube 201, reducing signal loss during transmission. This structure not only improves the efficiency of radio frequency signal transmission but also enhances the stability and anti-interference capability of the system.

[0031] The working principle of this utility model:

[0032] In use, the modular design ensures compatibility and installation flexibility with various RF devices. The structure includes a broadband impedance matching unit 1, with a first connector 2 screwed to one end for connecting to an RF signal source and a second connector 3 screwed to the other end for connecting to a load. The second connector 3 has an external limiting groove 4 for positioning and an internally fixed first rod 5 for signal transmission. Users can replace the first connector 2 and the second connector 3 according to different device requirements to ensure the matching unit matches the device interface. During installation, the matching unit is connected to the RF signal source via the first connector 2 and to the load via the second connector 3, secured using the limiting groove 4. The broadband matching network within the matching unit 1 provides excellent impedance matching over a wide frequency range, reducing signal reflection and improving transmission efficiency. RF testing equipment allows for dynamic adjustment of the matching network parameters to optimize matching performance for different frequencies or environmental conditions. This modular design not only solves the environmental requirements of traditional integrated impedance matching units during additional installations but also provides greater flexibility and adaptability to meet the broadband impedance matching needs of different RF systems.
