Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a micro rectangular radio frequency cluster connector structure. Background Technology

[0002] In the field of radio frequency signal transmission, the demand for multi-channel high-density connections is growing, but conventional radio frequency bundle connectors have significant technical limitations and are difficult to adapt to miniaturized and convenient application scenarios.

[0003] Conventional RF cluster connectors are connected to printed circuit boards by soldering or crimping. This not only requires a large installation space and limits compatibility, but also forms a fixed connection structure after installation, making it impossible to disassemble for subsequent debugging or repair. This increases maintenance costs and operational difficulty, resulting in poor practical performance of RF cluster connectors.

[0004] In conventional RF cluster connectors, the connector body is fixed by either a positioning gripper or an interference fit. The traditional positioning gripper design is relatively large in size, which takes up extra space and is not conducive to high-density integration. While the interference fit is relatively compact, it cannot be removed and reassembled, making it inconvenient to remove and adjust the connector body later. Utility Model Content

[0005] To address the above problems, this utility model provides a micro rectangular radio frequency cluster connector structure, which solves the aforementioned issues.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a micro rectangular radio frequency cluster connector structure, including a fixed base and a connector body mounted on the fixed base. The connector body includes an outer conductor and an inner conductor. A floating outer groove is formed in the middle of the outer conductor. An outer spring is provided in the floating outer groove. An outer fixed shell is provided in the floating outer groove. One end of the outer fixed shell is connected to one end of the outer spring.

[0007] The outer conductor is internally connected to two positioning blocks, and the outer part of the inner conductor is externally connected to the inside of one of the positioning blocks. One end of the inner conductor is provided with a floating inner groove, and an inner spring is provided inside the floating inner groove.

[0008] The floating inner groove is internally connected to an inner float, one end of which is connected to one end of an inner spring, and the outside of which is connected to the inside of another positioning block.

[0009] Preferably, one end of the inner conductor is connected to a conductive element, the inside of the outer conductor is connected to a conductive tube, and the outside of the conductive element is connected to the inside of the conductive tube.

[0010] Preferably, a mounting plate is connected to one side of the fixing base, and the mounting plate has a plurality of mounting holes, in which the connector body is installed.

[0011] Preferably, two through grooves are formed on the inner wall of the mounting hole, and two slots are formed on the inner wall of the mounting hole.

[0012] Preferably, the outer casing has two protrusions on its external connection, and the two protrusions are installed in two slots.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This application uses floating inner and outer conductors to connect the RF connector and the printed circuit board without the need for soldering or crimping, which are inconvenient for disassembly and debugging. This facilitates the disassembly and debugging of the RF connector and the printed circuit board, solving the problem that conventional RF cluster connectors are connected to the printed circuit board by soldering or crimping, which not only requires a large installation space but also makes it impossible to disassemble and debug after installation. This is beneficial to improving the practical performance of the RF cluster connector.

[0015] 2. This application uses the outer shell to engage with the mounting plate, allowing the connector body to be quickly installed and removed from the mounting plate. This solves the problem that conventional RF cluster connectors use positioning grippers or interference fits to fix the connector body, resulting in a large size and difficulty in removing and adjusting the connector body. This helps to reduce the size of the RF cluster connector and facilitates the removal and adjustment of the connector body. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] Please see Figures 1 to 5 A micro rectangular RF cluster connector structure includes a mounting base 1 and a connector body 3 mounted on the mounting base 1. The mounting base 1 is mounted on a printed circuit board by bolts. At this time, one end of the outer conductor 4 of several connector bodies 3 on the mounting base 1 is connected to one end of the printed circuit board to form a conductive connection. The inner floating part 13 in the inner conductor 10 is also connected to one end of the printed circuit board to form a conductive connection, thereby completing the installation of the RF cluster connector and the printed circuit board.

[0024] Printed circuit boards are a well-known technology, and those skilled in the art can and should understand their specific functions and structures, so they will not be described in detail here.

[0025] The connector body 3 includes an outer conductor 4 and an inner conductor 10. A floating outer groove 5 is provided in the middle of the outer conductor 4. An outer spring 6 is provided in the floating outer groove 5. An outer fixed shell 7 is provided in the floating outer groove 5. One end of the outer fixed shell 7 is connected to one end of the outer spring 6. When the RF cluster connector is installed with the printed circuit board, one end of the outer conductor 4 is connected to the printed circuit board. They are in floating contact. Specifically, the printed circuit board and one end of the outer conductor 4 are in contact to generate a squeezing force, which causes the outer conductor 4 to move in the fixed seat 1. More specifically, the movement of the floating outer groove 5 of the outer conductor 4 squeezes the outer spring 6. The outer fixed shell 7 and the mounting plate 2 form a positioning and fixation. Therefore, the outer spring 6 will not be displaced. So the outer conductor 4 can normally squeeze the spring 6 to form a floating structure.

[0026] The outer conductor 4 has two internal positioning blocks 9, and the outer conductor 10 is externally connected to the inside of one of the positioning blocks 9. One end of the inner conductor 10 has a floating inner groove 11, and an inner spring 12 is provided inside the floating inner groove 11. It should be noted that when the RF cluster connector is installed with the printed circuit board, not only the outer conductor 4 floats in contact with the printed circuit board, but the inner conductor 10 also floats in contact with the printed circuit board. Specifically, the inner floating part 13 of the inner conductor 10 is connected to the printed circuit board to form a conductive connection with the inner conductor 10.

[0027] More specifically, when one end of the inner float 13 contacts the printed circuit board, the printed circuit board and one end of the inner float 13 contact each other to generate a squeezing force, causing the other end of the inner float 13 to move in the floating inner groove 11 and squeeze the inner spring 12 in the floating inner groove 11 to form a float.

[0028] By floating the inner conductor 10 and the outer conductor 4 respectively, the RF connector and the printed circuit board do not need to be connected by soldering or crimping, which are inconvenient to disassemble and debug. This makes it easier to disassemble the RF connector and the printed circuit board for debugging, and solves the problem that conventional RF cluster connectors are connected to the printed circuit board by soldering or crimping, which not only requires a large installation space, but also cannot be disassembled and debugged after installation.

[0029] An inner float 13 is internally connected to the floating inner groove 11. One end of the inner float 13 is connected to one end of the inner spring 12. The outside of the inner float 13 is connected to the inside of another positioning block 9. It should be noted that when the inner float 13 floats, it will float inside the positioning block 9. The positioning block 9 will guide the inner float 13. At the same time, the inner float 13 has a limit ring at one end of the floating inner groove 11, so that the inner float 13 can float normally in the floating inner groove 11 without falling out of the floating inner groove 11.

[0030] One end of the inner conductor 10 is connected to a conductive element 14, and the inner part of the outer conductor 4 is connected to a conductive tube 8. The outside of the conductive element 14 is connected to the inside of the conductive tube 8. The inner float 13 of the inner conductor 10 is in contact with the printed circuit board, forming a conductive line of inner float 13, inner conductor 10, conductive element 14, and conductive tube 8. The floating of the inner float 13 is only a floating of position. No matter where the inner float 13 floats, the inner conductor 10 is connected to the inner float 13.

[0031] A mounting plate 2 is connected to one side of the fixed base 1. The mounting plate 2 is connected to the fixed base 1 by bolts, and several connector bodies 3 are fixedly installed on the fixed base 1 to form an RF cluster connector. Several mounting holes 201 are opened on the mounting plate 2, and the connector bodies 3 are installed in the mounting holes 201.

[0032] Two through slots 202 are provided on the inner wall of the mounting hole 201, and two slots 203 are provided on the inner wall of the mounting hole 201. When connecting the connector body 3 to the mounting plate 2, the connector body 3 needs to be inserted into the mounting hole 201 on the mounting plate 2 first. It is important to note that the two protrusions 701 on the outer side of the outer shell 7 on the connector body 3 should be aligned with the two through slots 202 on the mounting hole 201. In this way, the connector body 3 will drive the protrusions 701 through the mounting hole 201.

[0033] Then, rotate the connector body 3 so that the two protrusions 701 are aligned with the two slots 203 on the mounting hole 201. Then pull the connector body 3 back so that the two protrusions 701 are inserted into the slots 203. At this time, the connector body 3 will no longer rotate. Finally, install the fixing seat 1 and the mounting plate 2 together. The fixing seat 1 and the mounting plate 2 will cooperate to position and install the connector body 3.

[0034] This allows the connector body 3 to be quickly installed and removed from the mounting plate 2, solving the problem that the conventional RF cluster connectors use positioning grippers or interference fits to fix the connector body 3, resulting in a large size and making it inconvenient to remove and adjust the connector body 3. This helps to reduce the size of the RF cluster connector and makes it easier to remove and adjust the connector body 3.

[0035] The outer housing 7 has two protrusions 701 on its external connection, which are installed in two slots 203.

[0036] When using this utility model:

[0037] First, connect the connector body 3 to the mounting plate 2. Insert the connector body 3 into the mounting hole 201 on the mounting plate 2. The two protrusions 701 on the outer side of the outer shell 7 on the connector body 3 should be aligned with the two through slots 202 on the mounting hole 201. In this way, the connector body 3 will drive the protrusions 701 through the mounting hole 201.

[0038] Secondly, rotate the connector body 3 so that the two protrusions 701 are aligned with the two slots 203 on the mounting hole 201. Then pull the connector body 3 back so that the two protrusions 701 are inserted into the slots 203. At this time, the connector body 3 will no longer rotate. Finally, install the fixing seat 1 and the mounting plate 2 together. The fixing seat 1 and the mounting plate 2 will cooperate to position and install the connector body 3.

[0039] Then, the mounting base 1 is installed on the printed circuit board by bolts. At this time, one end of the outer conductor 4 of several connector bodies 3 on the mounting base 1 is connected to one end of the printed circuit board to form a conductive connection. The inner floating part 13 in the inner conductor 10 is also connected to one end of the printed circuit board to form a conductive connection. This completes the installation of the RF cluster connector and the printed circuit board. One end of the outer conductor 4 is connected to the printed circuit board, and they float in contact. Specifically, the printed circuit board and one end of the outer conductor 4 contact each other to generate a squeezing force, which causes the outer conductor 4 to move in the mounting base 1. More specifically, the floating outer groove 5 of the outer conductor 4 moves to squeeze the outer spring 6, while the outer shell 7 and the mounting plate 2 form a positioning fixation. Therefore, the outer spring 6 will not be displaced. So the outer conductor 4 can normally squeeze the spring 6 to form a floating connection.

[0040] Finally, during the installation of the RF cluster connector and the printed circuit board, not only does the outer conductor 4 float in contact with the printed circuit board, but the inner conductor 10 also floats in contact with the printed circuit board. Specifically, the inner floating member 13 of the inner conductor 10 connects and cooperates with the printed circuit board to form a conductive connection with the inner conductor 10. More specifically, when one end of the inner floating member 13 contacts the printed circuit board, the contact between the printed circuit board and one end of the inner floating member 13 generates a squeezing force, causing the other end of the inner floating member 13 to be in the floating inner groove 11.

[0041] The middle moves and squeezes the inner spring 12 in the floating inner groove 11 to form a float.
