Technical Field
[0001] The present invention relates to the technical field of electronic equipment, and in particular to a fixing device for a PCB board and a connector, and electronic equipment. Background Art
[0002] To ensure signal quality, the RF connector and PCB must be as close together as possible. During high-frequency or high-speed signal testing, to ensure impedance matching between the RF connector and the high-speed or high-frequency PCB interface and to ensure signal integrity, the RF connector mounted at the end of the PCB and the PCB's signal lines and grounding must maintain the integrity of the signal and return paths, with no gaps.
[0003] Traditional technologies typically employ press-fit connectors or integrated designs with encapsulated housings. These are limited by the connector installation method, the size of the connector and PCB, and manufacturing process errors, making it difficult to achieve zero clearance in mating accuracy. While zero clearance can be achieved, it requires the connector and PCB to be oversized, resulting in excessive signal attenuation due to excessive signal loop length. Furthermore, when RF connectors are connected to both ends of a PCB, the PCB cannot simultaneously achieve zero clearance with both RF connectors. Summary of the Invention

Figure 2 FIG. 1 is a schematic structural diagram showing another angle of fixing the PCB board 200 and the connector 300 by the fixing device 100 according to an embodiment of the present invention. Figure 3 is a schematic structural diagram of a fixing device 100 according to an embodiment of the present invention from an angle. Figure 4 is a schematic structural diagram of a fixing device 100 according to an embodiment of the present invention from another angle. Figure 5 FIG is a schematic cross-sectional view of a fixing device 100 according to an embodiment of the present invention. Figures 1 to 5As shown, in a specific embodiment, the fixing device 100 for the PCB board 200 and the connector 300 includes a package housing 10 and at least one mounting assembly 20. The package housing 10 includes two housings 11 arranged opposite to each other. Both housings 11 have a mounting platform 111 and at least one mounting hole 112. The PCB board 200 is placed on the mounting platforms 111 of the two housings 11. A plurality of connectors 300 are respectively inserted into the mounting holes 112 of the two housings 11, and the pins 310 of each connector 300 overlap with the PCB board 200. The mounting assembly 20 is configured to connect the two housings 11 after the PCB board 200 and the connector 300 are installed on the package housing 10, thereby fixing the PCB board 200 and the connector 300. See. Figure 1 The mounting platforms 111 of the two housings 11 jointly support the PCB board 200. The connector 300 here is a radio frequency connector. After the mounting assembly 20 connects the two housings 11, a welding tool is used to weld the PCB board 200 to the pins 310 of the connector 300.
[0037] This embodiment adopts a split design for the packaging shell 10, splitting it into two shells 11. After ensuring that the connectors 300 at both ends of the PCB board 200 are fitted with the PCB board 200 with zero clearance, the two shells 11 are connected. It can be suitable for any board edge connector 300 and PCB board 200 of any size. The gap between the connector 300 and the PCB board 200 can be freely adjusted, and the requirement of zero clearance fitting between the PCB board 200 and the connectors 300 at both ends can be met, thereby ensuring the continuity of the signal path and ensuring signal quality.
[0038] In some embodiments, each housing 11 is equipped with two connectors 300. That is, two connectors 300 are installed on each side of the PCB 200, and the two connectors 300 on the two housings 11 are aligned one-to-one. In other embodiments, the number of connectors 300 installed on each housing 11 can be determined based on specific design requirements. For example, each housing 11 can be equipped with one, three, or four connectors 300. The length of the housing 11 can be designed based on the length of the PCB 200 and the number of connectors 300.
[0039] In some embodiments, each housing 11 is in an elongated shape, and the mounting platform 111 extends along the length of the housing 11. In other embodiments, the shape of the housing 11 can also be determined according to specific design requirements, and can be specifically designed according to the shape of the PCB board 200.
[0040] In some embodiments, the mounting holes 112 are arranged along the width direction of the housing 11, and the side of the mounting holes 112 close to the mounting platform 111 is higher than the mounting platform 111, so that the pins 310 of the connector 300 extend out of the mounting holes 112 and overlap with the PCB board 200, see Figure 1 The pins 310 of the connector 300 need to extend from the mounting holes 112 and be located above the PCB board 200 in order to overlap with the PCB board 200. Operating space is left at the top of the two housings 11 to facilitate soldering the PCB board 200 to the pins 310 of the connector 300 using a soldering tool.
[0041] In some embodiments, mounting hole 112 includes a first portion and a second portion. The second portion is located on a side of the first portion closer to mounting platform 111. The diameter of the first portion is larger than the diameter of the second portion. When connector 300 is installed, the body of connector 300 is located within the first portion, and the pins 310 of connector 300 are located within the second portion. Thus, mounting hole 112 can be used to define the position of connector 300.
[0042] In some embodiments, the connector 300 is detachably connected to the housing 11. Figure 2 and Figure 3 After the connector 300 is inserted into the mounting hole 112, the two ends of the connector 300 are fixed to the corresponding housing 11 using bolts, thereby completing the installation of the connector 300. When the connector 300 needs to be removed from the housing 11, it can be removed by simply unscrewing the bolts. The connector 300 of the present invention is relatively easy to assemble and disassemble, and the assembly and disassembly efficiency is high.
[0043] In some embodiments, the number of mounting holes 112 on each housing 11 is the same and arranged in a one-to-one correspondence. In other embodiments, the number of mounting holes 112 on each housing 11 can also be determined according to specific design requirements, and can be designed to be non-corresponding and staggered.
[0044] In some embodiments, there are multiple mounting components 20 , and at least one mounting component 20 is provided at both ends of the housing 11 along the length direction, so that the housing 11 can be fixed.
[0045] In one embodiment, each mounting assembly 20 includes a mounting plate 21 and at least two connectors 22. The connectors 22 are bolts. The mounting plate 21 is square and sized to the ends of the housing 11. After the mounting plate 21 is placed at the ends of the housing 11, it is bolted to the two housings 11, securing the housings 11. In other embodiments, the mounting assembly 20 may utilize components of other structures, as long as they meet the mounting requirements of the two housings 11.
[0046] In some embodiments, at least one mounting assembly 20 is located at the bottom of the housing 11, see Figure 2 In this embodiment, two mounting assemblies 20 are provided at the bottom of the housing 11. In other embodiments, three, four, or five mounting assemblies 20 may be provided at the bottom of the housing 11, depending on the extension length of the housing 11. The longer the extension length of the housing 11, the more mounting assemblies 20 are provided, and the shorter the extension length of the housing 11, the fewer mounting assemblies 20 are provided.
[0047] In this embodiment, both ends and the bottom of the two housings 11 are secured by the mounting assembly 20, thereby improving the stability of the connection between the two housings 11. Furthermore, the gap between the two housings 11 can be adjusted based on the size of the PCB 200, ensuring a zero-clearance fit between both ends of the PCB 200 and the connector 300. To accommodate PCBs 200 of varying sizes, the gap between the two housings 11 will vary, necessitating the design of mounting plates 21 of the mounting assembly 20 of varying sizes. This ensures that, regardless of the size of the gap between the two housings 11, there is a suitable mounting plate 21 for installation.
[0048] In some embodiments, at least one guide hole 113 is provided on each of the two housings 11. The guide holes 113 on the two housings 11 are arranged in a one-to-one correspondence. The fixing device 100 further includes at least one guide post 30. Each guide post 30 is passed through the corresponding guide hole 113 of the two housings 11 to guide and position the two housings 11, thereby improving the installation efficiency of the two housings 11. Figure 2 .
[0049] In some embodiments, there are multiple guide holes 113, each located near the two ends of the housing 11. In other words, the guide holes 113 are distributed at both ends of the housing 11. When the two housings 11 move toward or away from each other, they can be guided by the guide posts 30 of the guide holes 113, thereby preventing the two housings 11 from shifting, thereby improving installation efficiency.
[0050] In some embodiments, each housing 11 is provided with two guide holes 113, and the two guide holes 113 are arranged along the diagonal lines of the housing 11. When the two housings 11 are arranged opposite each other, the line connecting the two guide holes 113 on one housing 11 intersects the line connecting the two guide holes 113 on the other housing 11, which is equivalent to providing guide posts 30 at all four corners of the housing 11.
[0051] This embodiment further provides an electronic device, which includes the fixing device 100 according to any one of the above embodiments. Detailed description of the fixing device 100 is omitted here.
[0052] This embodiment utilizes a split design for the package housing 10. During assembly of the connector 300, package housing 10, and PCB 200, the gap between the two housings 11 of package housing 10 can be adjusted to achieve zero-clearance fit between the PCB 200 and the connectors 300 at both ends, thereby ensuring signal path continuity and quality. Furthermore, the split package housing 10 overcomes the size limitations of the connector 300 and PCB 200, making it compatible with any edge-of-board connector 300 and PCB of any size, offering increased adaptability.
[0053] At this point, those skilled in the art will recognize that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
