Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to a connector fixing device and circuit board assembly. Background Technology

[0002] Crimp connectors, such as fisheye connectors, connect to circuit boards via crimping. Specifically, the connector has connecting terminals, such as fisheye terminals. The circuit board has insertion holes. Through the elastic deformation of the connecting terminals within the insertion holes, the connecting terminals are smoothly inserted into the insertion holes to maintain the connection with the circuit board, thus achieving an electrical connection between the connecting terminals and the circuit board.

[0003] However, connectors in related technologies are prone to floating or falling off after crimping, which seriously affects the signal integrity and reliability of the system, causing bit errors or even service interruptions. Summary of the Invention

[0004] To solve the above-mentioned technical problems, or at least partially solve them, this application provides a connector fixing device and circuit board assembly, which can, to a certain extent, prevent the connector from floating or falling off, thereby improving the integrity and reliability of system signals.

[0005] In a first aspect, this application provides a connector fixing device, wherein the connector has connecting terminals for crimping with the insertion holes of a circuit board, and the connector fixing device includes: a support frame and a crimping structure; The support frame spans the connector and is connected to the circuit board; The crimping structure is disposed on the support frame and is located on the side of the connector opposite to the circuit board, so as to crimp the connector onto the circuit board at least from the crimping direction of the connection terminal.

[0006] The connector fixing device provided in this application, by setting a support frame and a crimping structure, allows the support frame to straddle the connector and connect the support frame to the circuit board. The crimping structure is set on the support frame and located on the side of the connector away from the circuit board. This allows the crimping structure to apply pressure to the connector at least from the insertion direction of the connector's connection terminal into the mating hole of the circuit board. By crimping the connector onto the circuit board, the stability of the crimping between the connection terminal and the mating hole is improved. This, to a certain extent, avoids the connector from floating or falling off during product insertion and removal or long-term use, improves signal integrity and reliability, and avoids system communication interruption or bit errors.

[0007] Optionally, the crimping structure includes a crimping member; The support frame has a mounting hole area on the side of the connector opposite to the circuit board, and the crimping member is disposed in the mounting hole area to crimp the connector onto the circuit board.

[0008] This design improves the assembly efficiency and stability of the crimping components, and also enhances the overall compactness of the fixing device.

[0009] Optionally, the crimping member is detachably connected to the support frame via fasteners.

[0010] This design allows for easy separation of the crimping component and support frame in case of breakage or damage. Only the damaged component needs to be replaced, preventing the entire fixing device from being scrapped and saving costs.

[0011] Optionally, the fastener is a screw; The crimping member is provided with a first connecting hole, and the support frame is provided with a second connecting hole at a position corresponding to the first connecting hole. The axial directions of the first connecting hole and the second connecting hole are perpendicular to the crimping direction of the connecting terminal. The screw is sequentially inserted into the second connecting hole and the first connecting hole to connect the crimping member to the support frame.

[0012] The connection between the crimping component and the support frame is achieved by screws, which is convenient and reliable. Moreover, this design allows the crimping structure to effectively crimp the connector while avoiding over-pressure on the connector caused by driving screws from the crimping direction of the connection terminal. In other words, the connector is effectively protected while preventing it from floating or falling off.

[0013] Optionally, the outer surface of the screw has an anti-loosening layer.

[0014] This design further improves the reliability of the connection between the crimping component and the support frame, preventing the connection between the crimping component and the support frame from loosening due to loose screws. This further improves the stability of the crimping component, ensuring the crimping effect of the crimping component on the connector, and thus ensuring the stability of the connector.

[0015] Optionally, a limiting structure is further provided between the crimping member and the mounting hole area, the limiting structure being used to at least restrict the movement of the crimping member in a direction away from the connector.

[0016] This further improves the stability of the crimping component, thereby ensuring the crimping effect of the crimping component on the connector and improving the stability of the fit between the connector and the circuit board.

[0017] Optionally, the limiting structure includes a first inclined surface and a second inclined surface; The crimping member has an end wall and a side wall. The end wall is disposed opposite to the side of the connector that is away from the circuit board. The side wall extends from the edge of the end wall toward a direction away from the connector. In the crimping direction along the connection terminal, the side wall is inclined outward to form the first inclined surface. The mounting hole area has a second inclined surface at the position corresponding to the side wall. In the crimping direction of the connecting terminal, the second inclined surface extends outward at an angle to stop the first inclined surface in a direction opposite to the crimping direction.

[0018] By setting the limiting structure in this way, not only can the crimping component be effectively prevented from moving away from the connector, thus ensuring the stable crimping effect of the crimping component on the connector, but also, when the crimping component is assembled into the mounting hole area, the first inclined surface and the second inclined surface cooperate to guide the crimping component during installation, enabling the crimping component to enter the mounting hole area quickly and smoothly, thus improving assembly efficiency.

[0019] Optionally, the crimping member is an elastic crimping member.

[0020] This design ensures effective crimping of the connector while preventing overpressure and damage. Furthermore, by using a flexible crimping element, the required precision of the fit between the crimping element and the mounting hole area is reduced, improving manufacturing efficiency.

[0021] Optionally, the crimping structure further includes a cover plate located on the side of the crimping member away from the connector and connected to the support frame, so that the crimping member crimps the connector onto the circuit board.

[0022] This design further improves the stability of the crimping component, thereby enhancing the crimping effect on the connector.

[0023] Optionally, the cover plate is provided with a first limiting part, and the support frame is provided with a second limiting part. The first limiting part and the second limiting part are matched and connected to position the cover plate.

[0024] This design makes the assembly of the cover plate more convenient, improves assembly efficiency, and further enhances the stability of the cover plate, thereby improving the stability of the press-fit component.

[0025] Optionally, a recessed groove is provided on the side of the support frame away from the circuit board, the recessed groove being recessed toward the circuit board, and the mounting hole area is provided on the bottom wall of the recessed groove. The cover plate is located inside the sink, and the side of the cover plate facing away from the connector does not protrude from the opening of the sink.

[0026] This design further improves the ease of assembly and stability of the cover plate. By placing the mounting hole area on the bottom wall of the sink, the side of the cover plate away from the connector does not protrude from the sink opening, thus improving the compactness of the overall structure and reducing the space occupied.

[0027] Optionally, the crimping member has a first positioning part, and the support frame has a second positioning part, wherein the first positioning part and the second positioning part are matched and connected to position the crimping member.

[0028] This design improves the convenience and reliability of connecting the crimping component to the support frame, thereby ensuring the crimping effect of the crimping component on the connector.

[0029] Optionally, the outer wall of the crimping member has an external thread, the crimping member passes through the mounting hole area, and the inner wall of the mounting hole area has an internal thread that is threadedly connected to the crimping member. One end of the crimping member abuts against the connector to crimp the connector onto the circuit board.

[0030] In this way, during use, simply insert the crimping piece into the mounting hole area and screw it in so that it faces the connector to press against it. This is convenient and reliable, ensuring a secure connection between the crimping piece and the support frame while simultaneously preventing the connector from floating or falling off. Furthermore, the pressure applied to the connector can be adjusted by screwing the crimping piece, allowing for flexible pressure control and preventing overpressure.

[0031] Optionally, a force-bearing buffer is provided on the side of the connector facing away from the circuit board, and one end of the crimping member abuts against the force-bearing buffer to crimp the connector onto the circuit board.

[0032] This design allows the crimping component to directly press against the force-bearing buffer, thereby indirectly crimping the connector onto the circuit board. This not only prevents the connector from floating or falling off, but also avoids damage caused by overpressure to a certain extent.

[0033] Optionally, the crimping element is a screw.

[0034] This setup is simple and easy to operate.

[0035] Optionally, the support frame has a cover cavity that covers the connector, and the mounting hole area is located on the cavity wall of the cover cavity on the side away from the circuit board, and the mounting hole area communicates with the cover cavity.

[0036] This design prevents the connector from floating or falling off, while effectively protecting the connector from the cavity.

[0037] Optionally, there are at least two cavities, and the at least two cavities are arranged sequentially at intervals along the length of the support frame, with one cavity corresponding to one connector.

[0038] This allows multiple connectors to be fixed simultaneously using a support frame and multiple crimping structures mounted on that support frame, making operation convenient and improving assembly efficiency.

[0039] Optionally, the support frame is connected to the circuit board via connectors, and the connectors are respectively provided on at least two sides along the length direction of the support frame.

[0040] This allows for the connection of the entire fixing device to the circuit board simply by connecting both ends of the support frame, making the operation convenient and the connection reliable.

[0041] Optionally, an intermediate connecting portion is provided between two adjacent cavities, and the connecting member is provided on the intermediate connecting portion.

[0042] This design further improves the stability and reliability of the connection between the support frame and the circuit board, thereby further improving the crimping effect of the crimping component on the connector.

[0043] Secondly, this application provides a circuit board assembly, including a connector, a circuit board, and a connector fixing device as described above.

[0044] The circuit board assembly provided in this application, by configuring its connector fixing device to include a support frame and a crimping structure, allows the support frame to straddle the connector and connect the support frame to the circuit board. The crimping structure is disposed on the support frame and located on the side of the connector away from the circuit board. This allows the crimping structure to apply pressure to the connector at least from the connector's connection terminal to the mating hole of the circuit board in the insertion direction. By crimping the connector onto the circuit board through the crimping structure, the stability of the crimping between the connection terminal and the mating hole is improved. This, to a certain extent, avoids the connector from floating or falling off during product insertion and removal or long-term use, improves signal integrity and reliability, and avoids system communication interruption or bit errors.

Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of this application more apparent, exemplary embodiments according to this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0050] It should be understood that the steps described in the method embodiments of this application may be performed in different orders and / or in parallel. Furthermore, the method embodiments may include additional steps and / or omit the steps shown. The scope of this application is not limited in this respect.

[0051] The term "comprising" and its variations as used herein are open-ended, meaning "including but not limited to". The term "based on" means "at least partially based on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Definitions of other terms will be given in the following description. It should be noted that the concepts of "first", "second", etc., mentioned in this application are used only to distinguish different devices, modules, or units, and are not intended to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0052] It should be noted that the terms "a" and "a plurality of" used in this application are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0053] Crimp connectors, such as fisheye connectors, achieve electrical connection to a circuit board through crimping. Specifically, the connector has connecting terminals, such as fisheye terminals, which have fisheye holes. When the fisheye terminal is compressed, it undergoes elastic deformation. The circuit board has insertion holes. Through the elastic deformation of the connecting terminal in the insertion hole, the connecting terminal is smoothly inserted into the insertion hole to maintain the connection with the circuit board, thereby achieving electrical connection between the connecting terminal and the circuit board.

[0054] However, connectors in related technologies are prone to floating or falling off after crimping, severely affecting the signal integrity and reliability of the system, causing bit errors or even service interruptions. While directly creating screw holes on the bottom of the connector to fix it to the circuit board with screws is an option, this would alter the connector's structure, making it unsuitable for some high-density products.

[0055] Based on this, this application provides a connector fixing device and a circuit board assembly. By setting a support frame and a crimping structure, the support frame is straddling the connector, connecting the support frame to the circuit board. The crimping structure is set on the support frame and located on the side of the connector away from the circuit board, so that the crimping structure crimps the connector from the connection terminal to the mating hole in the crimping direction, improving the stability and reliability of the connection between the connector and the circuit board, and avoiding the phenomenon of the connector floating or falling off after crimping, thereby improving the integrity and reliability of the system signal.

[0056] The connector fixing device and circuit board assembly provided in this application will be described in detail below with reference to the accompanying drawings and specific embodiments: Reference Figures 1 to 13 As shown, this embodiment provides a connector fixing device 100. The connector 200 has connecting terminals, which may be located at the bottom of the connector 200. The connecting terminals are used for crimping with the insertion holes of the circuit board 300. The connecting terminals may be, for example, fisheye terminals. The connector 200 may be, for example, a right-angle connector.

[0057] The connector fixing device 100 includes a support frame 1 and a crimping structure 2. The support frame 1 spans across the connector 200 and is connected to the circuit board 300.

[0058] For example, the support frame 1 can be connected to the circuit board 300 via a connector 5, such as a screw. The support frame 1 has a mounting hole 17, and the circuit board 300 has a screw hole at the position corresponding to the mounting hole 17. The screw passes through the mounting hole 17 and the screw hole, thereby realizing the connection between the support frame 1 and the circuit board 300.

[0059] Of course, in other implementations, the connector 5 can also be a bolt, a fixing clip, or other structure.

[0060] The crimping structure 2 is disposed on the support frame 1 and is located on the side of the connector 200 away from the circuit board 300, so as to crimp the connector 200 onto the circuit board 300 at least from the crimping direction of the connection terminal.

[0061] The crimping direction of the connection terminal here can be specifically... Figure 4 The Z-direction in the middle.

[0062] After the connector 200's connecting terminals are inserted into the sockets of the circuit board 300, the support frame 1 is placed across the connector 200 and connected to the circuit board 300. The crimping structure 2 is then connected to the support frame 1, positioned on the side of the connector 200 away from the circuit board 300. This allows the crimping structure 2 to apply pressure to the connector 200 from its crimping direction, ensuring the connecting terminals remain stably in the sockets and preventing the connector 200 from floating or falling out, thereby improving the integrity and reliability of the system signals.

[0063] The connector fixing device 100 provided in this application embodiment, by setting a support frame 1 and a crimping structure 2, allows the support frame 1 to straddle the connector 200 and connect the support frame 1 to the circuit board 300. The crimping structure 2 is set on the support frame 1, with the crimping structure 2 located on the side of the connector 200 away from the circuit board 300. This allows the crimping structure 2 to apply pressure to the connector 200 at least from the insertion direction of the connector 200's connection terminal into the insertion hole on the circuit board 300. By crimping the connector 200 onto the circuit board 300 through the crimping structure 2, the stability of the crimping between the connection terminal and the insertion hole is improved. This, to a certain extent, avoids the connector 200 from floating or falling off during product insertion and removal or long-term use, thereby improving signal integrity and reliability and avoiding system communication interruptions or bit errors.

[0064] The connector fixing device 100 provided in this application embodiment can meet the needs of high-speed, high-bandwidth and easy-to-maintain single-board blind mating architecture, such as meeting the system service requirements of 112G / 224G, and realizing the reliable application of 112G / 224G high-speed systems.

[0065] In some embodiments, the crimping structure 2 specifically includes a crimping member 21. The corresponding connector 200 of the support frame 1 has a mounting hole area 11 on the side away from the circuit board 300. The crimping member 21 is disposed in the mounting hole area 11 to crimp the connector 200 onto the circuit board 300.

[0066] This design improves the assembly efficiency and stability of the crimping component 21, and enhances the overall compactness of the fixing device, saving space.

[0067] Reference Figures 1 to 7 As shown, in some embodiments, the crimping member 21 is detachably connected to the support frame 1 via fasteners 3.

[0068] This design allows for easy separation of the two components if either the crimping member 21 or the support frame 1 is damaged. Only the damaged component needs to be replaced, preventing the entire fixing device from being scrapped and saving costs.

[0069] In some embodiments, fastener 3 may specifically be a screw. (Continue referring to...) Figures 1 to 7 As shown, the crimping member 21 is provided with a first connecting hole 211, and the support frame 1 is provided with a second connecting hole 12 at a position corresponding to the first connecting hole 211. The axial direction of the first connecting hole 211 and the second connecting hole 12 is perpendicular to the crimping direction of the connecting terminal. Screws are sequentially inserted into the second connecting hole 12 and the first connecting hole 211 to connect the crimping member 21 to the support frame 1.

[0070] Reference Figure 3 As shown, the crimping member 21 has an end wall 212 and a side wall. The end wall 212 is disposed opposite to the side of the connector 200 away from the circuit board 300, and is used to contact the top surface of the connector 200. The side wall is located to the side of the end wall and extends from the edge of the end wall in a direction away from the connector 200.

[0071] Reference Figure 4 and Figure 5 As shown, by way of example, the crimping member 21 can press down on the connector 200 from the top of the connector 200, and the first connection hole 211 of the crimping member 21 can be provided on the side wall of the crimping member 21.

[0072] This design ensures a reliable connection between the crimping structure 2 and the support frame 1, effectively fixing the connector 200 while preventing the connector 200 from being over-pressed due to screws being driven from the crimping direction of the connection terminals. It effectively protects the connector 200 by preventing it from floating or falling off.

[0073] For example, there can be multiple fasteners 3 between the crimping member 21 and the support frame 1. For instance, each side wall of the crimping member 21 is provided with a first connection hole 211, which further improves the reliability of the connection between the crimping member 21 and the support frame 1, thereby ensuring the crimping effect of the crimping member 21 on the connector 200 and ensuring the stability of the connector 200.

[0074] Combination Figures 5 to 7 As shown, the screws used to connect the crimping member 21 and the support frame 1 can be... Figure 6 The cylindrical screw shown can also be Figure 7 The capped screw shown.

[0075] Continue to combine Figure 4 and Figure 5As shown, for example, a first connecting hole 211 is provided on one side wall of the crimping member 21, and the first connecting hole 211 is connected to the corresponding second connecting hole 12 on the support frame 1 by a columnar screw.

[0076] The other side wall of the crimping member 21 is also provided with a first connecting hole 211, which is connected to the corresponding second connecting hole 12 on the support frame 1 by a cap screw. For example, the first connecting hole 211 can be set as a smooth hole, and the second connecting hole 12 can be set as a threaded hole, with the side wall of the cap screw having external threads only at the position corresponding to the second connecting hole 12.

[0077] Of course, in other implementations, both the first connecting hole 211 and the second connecting hole 12 can be set as threaded holes.

[0078] In some embodiments, the outer surface of the screw has an anti-loosening layer. This configuration further improves the reliability of the connection between the crimping member 21 and the support frame 1, preventing the screw from loosening due to shaking or vibration of the entire structure, which could lead to a loose connection between the crimping member 21 and the support frame 1. This further improves the stability of the crimping member 21, thereby enhancing the crimping effect of the crimping member 21 on the connector 200 and ensuring the stability of the connector 200.

[0079] For example, the anti-loosening layer can be a resin coating or a non-loosening adhesive coating applied to the outer surface of the screw. The coating will rebound when pressure is applied, which will enhance the friction between the threads and effectively prevent loosening caused by vibration or impact.

[0080] Reference Figures 1 to 5 As shown, in some embodiments, the crimping member 21 has a first positioning part 214 and the support frame 1 has a second positioning part 13. The first positioning part 214 and the second positioning part 13 are matched and connected to position the crimping member 21.

[0081] In this way, through the cooperation of the first positioning part 214 and the second positioning part 13, the crimping part 21 is pre-positioned on the support frame 1, making the connection between the crimping part 21 and the support frame 1 more stable, improving the convenience and reliability of the connection between the crimping part 21 and the support frame 1, and thus ensuring the crimping effect of the crimping part 21 on the connector 200.

[0082] For example, the first positioning part 214 can be a positioning protrusion, and the second positioning part 13 can be a positioning groove. When the crimping member 21 enters the mounting hole area 11, the positioning protrusion is located in the positioning groove, thereby realizing the positioning of the crimping member 21. The structure is simple and the positioning is reliable.

[0083] Reference Figure 2 and Figure 3As shown, there can be multiple first positioning parts 214. For example, first positioning parts 214 can be provided on both sides of the pressing part 21, and second positioning parts 13 correspond one-to-one with the first positioning parts 214, thereby improving the positioning effect.

[0084] Of course, in other implementations, the first positioning part 214 can also be a positioning groove, and correspondingly, the second positioning part 13 can be a positioning protrusion.

[0085] Continue to refer to Figures 2 to 5 As shown, in some embodiments, a limiting structure is also provided between the crimp member 21 and the mounting hole area 11, the limiting structure being used to at least restrict the crimp member 21 from moving in a direction away from the connector 200.

[0086] In this way, when the entire structure shakes or vibrates, the limiting structure can effectively limit the crimping member 21, preventing the crimping member 21 from shifting away from the connector 200, thereby further improving the stability of the crimping member 21, further ensuring the crimping effect of the crimping member 21 on the connector 200, and further improving the mating stability between the connector 200 and the circuit board 300.

[0087] In some embodiments, the limiting structure includes a first inclined surface 213 and a second inclined surface 111. The sidewall of the crimping member 21 is inclined outward in the crimping direction along the connecting terminal to form the first inclined surface 213.

[0088] The mounting hole area 11 has a second inclined surface 111 at the corresponding side wall position. The second inclined surface 111 extends outwardly in the crimping direction of the connecting terminal to stop the first inclined surface 213 in the opposite direction to the crimping direction.

[0089] By setting the limiting structure in this way, not only can the crimping member 21 be effectively prevented from moving away from the connector 200, thus ensuring the stable crimping effect of the crimping member 21 on the connector 200; but when the crimping member 21 is assembled into the mounting hole area 11, the first inclined surface 213 and the second inclined surface 111 cooperate to guide the crimping member 21 during installation, so that the crimping member 21 can quickly and smoothly enter the mounting hole area 11, improving the assembly efficiency.

[0090] Of course, in other implementations, the limiting structure can also be a retractable stop protrusion set on the side of the mounting hole area 11 away from the circuit board 300. When the crimping member 21 is inserted into the mounting hole area 11, the stop protrusion is compressed and retracts, allowing the crimping member 21 to smoothly enter the mounting hole area 11. After the crimping member 21 enters the mounting hole area 11, the force on the stop protrusion disappears, and the stop protrusion extends and stops on the side of the crimping member 21 away from the circuit board 300, thereby preventing the crimping member 21 from moving in a direction away from the circuit board 300.

[0091] In other implementations, the crimping component 21 can also be connected to the support frame 1 by means of glue, tape, etc.

[0092] The connector 200 is crimped by the weight of the crimping member 21, ensuring tight contact between the connector 200 and the crimping member 21. This effectively prevents the connector 200 from becoming raised or falling off due to insertion, removal, or collision during insertion and removal and turnover.

[0093] Furthermore, this design eliminates the need for screw holes or other connection structures on the connector 200, thus facilitating the layout of the connector 200 itself and meeting the requirements of high-density products. In addition, since the connector 200 is crimped using the crimping structure 2, the manufacturing precision requirements for the support frame 1 are reduced.

[0094] Reference Figures 8 to 11 As shown, in some embodiments, the crimping member 21 can be configured as an elastic crimping member.

[0095] This design ensures that the crimping member 21 effectively crimps the connector 200 while controlling the force on the crimping surface of the connector 200, thus preventing damage to the connector 200 due to excessive pressure from the crimping member 21. Furthermore, by setting the crimping member 21 as an elastic crimping member, the required precision of the fit between the crimping member 21 and the mounting hole area 11 is reduced, improving manufacturing efficiency.

[0096] For example, the elastic crimping member 21 can be a silicone crimping member, a foam crimping member, or a spring. For example, there can be one or more elastic crimping members, such as multiple elastic crimping members arranged along the top surface of the connector 200 to crimp the connector 200 together.

[0097] Furthermore, continue to refer to Figures 8 to 11 The crimping structure 2 may also include a cover plate 22, which is located on the side of the crimping member 21 away from the connector 200 and is connected to the support frame 1 so that the crimping member 21 crimps the connector 200 onto the circuit board 300.

[0098] This configuration further improves the stability of the crimping member 21, thereby enhancing the crimping effect of the crimping member 21 on the connector 200.

[0099] For example, the cover plate 22 can be a metal cover plate or a plastic cover plate, etc.

[0100] Reference Figure 10 and Figure 11As shown, for example, the cover plate 22 is provided with screw holes 222, and the support frame 1 is also provided with corresponding screw holes. The cover plate 22 is connected to the support frame 1 by screws 223 passing through the corresponding screw holes.

[0101] In some embodiments, a first limiting part 221 is provided on the cover plate 22, and a second limiting part 14 is provided on the support frame 1. The first limiting part 221 and the second limiting part 14 are matched and connected to position the cover plate 22.

[0102] This design makes the assembly of the cover plate 22 more convenient and improves the stability of the cover plate 22, thereby improving the stability of the press-fit component 21.

[0103] Continue to refer to Figure 10 and Figure 11 For example, the first limiting part 221 may be a limiting hole, and the second limiting part 14 may be a limiting protrusion that can extend into the limiting hole.

[0104] Of course, in other implementations, the first limiting part 221 can also be a limiting protrusion, and the second limiting part 14 can be a limiting hole.

[0105] Reference Figure 8 and Figure 11 As shown, in some embodiments, a recessed groove 15 is provided on the side of the support frame 1 away from the circuit board 300. The recessed groove 15 is recessed in the direction of the circuit board 300, and the mounting hole area 11 is provided on the bottom wall of the recessed groove 15.

[0106] The cover plate 22 is located inside the recess 15, and the side of the cover plate 22 facing away from the connector 200 does not protrude from the groove opening of the recess 15. For example, the top surface of the cover plate 22 can be flush with the groove opening of the recess 15, or the top surface of the cover plate 22 can be lower than the groove opening of the recess 15.

[0107] This design further improves the ease of assembly of cover plate 22 and the stability of cover plate 22.

[0108] By setting the mounting hole area 11 on the bottom wall of the recess 15, the side of the cover plate 22 facing away from the connector 200 does not protrude from the groove opening of the recess 15, thus improving the compactness of the overall structural layout and reducing the space occupied.

[0109] Reference Figure 8 and Figure 9 As shown, when the crimping member 21 is an elastic crimping member, a first positioning part 214 can also be provided on the crimping member 21. Correspondingly, the support frame 1 has a second positioning part 13. The first positioning part 214 and the second positioning part 13 are matched and connected to position the crimping member 21.

[0110] This configuration enables the positioning of the crimping member 21, thereby improving the stability of the crimping member 21 and ensuring the crimping effect of the crimping member 21 on the connector 200.

[0111] Reference Figure 8 and Figure 9 As shown, for example, the first positioning part 214 can be a positioning protrusion, and the second positioning part 13 can be a positioning groove. When the crimping member 21 enters the mounting hole area 11, the positioning protrusion is located in the positioning groove, thereby realizing the positioning of the crimping member 21. The structure is simple and the positioning is reliable.

[0112] Of course, in other implementations, for example, the first positioning part 214 can also be a positioning groove, and correspondingly, the second positioning part 13 can be a positioning protrusion.

[0113] For example, during assembly, the crimping member 21 is first placed into the mounting hole area 11. At this time, the first positioning part 214 and the second positioning part 13 are matched and connected. Then, the cover plate 22 is placed on the crimping member 21. The cover plate 22 is located in the recess 15. The first limiting part 221 and the second limiting part 14 are matched and connected. The cover plate 22 is locked on the support frame 1 by screws 223, thereby realizing the crimping of the connector 200 by the crimping member 21 and preventing the connector 200 from floating or falling off.

[0114] The connector 200 is crimped by the weight of the crimping structure 2 itself, ensuring tight contact between the connector 200 and the crimping structure 2. This effectively prevents the connector crimping surface from becoming raised or the connector 200 from falling off due to insertion, removal and collision during insertion and removal and turnover.

[0115] Furthermore, this design eliminates the need for screw holes or other connection structures on the connector 200, thus facilitating the layout of the connector 200 itself and meeting the requirements of high-density products. In addition, since the connector 200 is crimped using the crimping structure 2, the manufacturing precision requirements for the support frame 1 are reduced.

[0116] Reference Figure 12 and Figure 13 As shown, in some embodiments, the outer wall of the crimping member 21 has external threads (not shown in the figure), the crimping member 21 passes through the mounting hole area 11, and the inner wall of the mounting hole area 11 has internal threads (not shown in the figure) that are threadedly connected to the crimping member 21. That is, the mounting hole area 11 can be, for example, a threaded hole. One end of the crimping member 21 abuts against the connector 200 to crimp the connector 200 onto the circuit board 300.

[0117] In this way, during use, simply insert the crimping member 21 through the mounting hole area 11, and screw the crimping member 21 inwards towards the connector 200 to press against it. This is convenient and reliable. While ensuring a reliable connection between the crimping member 21 and the support frame 1, it also presses against the connector 200, ensuring a reliable connection between the connector 200 and the circuit board 300, preventing the connector 200 from floating or falling off. Furthermore, the pressure on the connector 200 can be adjusted by screwing the crimping member 21, allowing for flexible pressure regulation and preventing overpressure on the connector 200.

[0118] Furthermore, this design eliminates the need for screw holes or other connection structures on the connector 200, thus facilitating the layout of the connector 200 itself and meeting the requirements of high-density products. In addition, since the connector 200 is crimped using the crimping structure 2, the manufacturing precision requirements for the support frame 1 are reduced.

[0119] In some embodiments, the crimping member 21 can be a screw, which abuts the connector 200. This method is simple in structure, easy to assemble, and provides a good abutting effect.

[0120] Of course, in other implementations, the crimping component 21 can also be a stud or other structure.

[0121] Continue to refer to Figure 12 and Figure 13 As shown, in some embodiments, a force-bearing buffer 4 is provided on the side of the connector 200 away from the circuit board 300, and one end of the crimping member 21 abuts against the force-bearing buffer 4 to crimp the connector 200 onto the circuit board 300.

[0122] This configuration allows the crimping member 21 to directly abut against the force-bearing buffer member 4, thereby indirectly crimping the connector 200 onto the circuit board 300. While preventing the connector 200 from floating or falling off, it can also, to a certain extent, avoid damage to the connector 200 due to overpressure.

[0123] For example, the force-bearing buffer 4 may be made of plastic. Of course, it can also be made of elastic materials such as silicone. This application embodiment does not specifically limit the specific material of the force-bearing buffer 4.

[0124] Reference Figures 1 to 13 As shown, in some embodiments, the support frame 1 has a cavity 10 that covers the connector 200, and a mounting hole area 11 is disposed on the cavity wall of the cavity 10 away from the circuit board 300, and the mounting hole area 11 communicates with the cavity 10.

[0125] This design prevents the connector 200 from floating or falling off, while also allowing the housing 10 to protect the connector 200 to a certain extent.

[0126] Continue to refer to Figure 4 , Figure 11 and Figure 13 As shown, in some embodiments, there are at least two cavities 10, and the at least two cavities 10 are arranged sequentially at intervals along the length of the support frame 1, with one cavity 10 corresponding to one connector 200.

[0127] This allows multiple connectors 200 to be fixed simultaneously via a support frame 1 and multiple crimping structures 2 mounted on the support frame 1, making operation convenient and improving assembly efficiency.

[0128] In other words, the connector fixing device 100 can fix one connector 200 or multiple connectors 200 simultaneously. That is, the connector fixing device 100 can provide floating and drop protection for a single connector 200, or it can provide floating and drop protection for a connector group formed by multiple connectors 200 arranged side by side.

[0129] In some embodiments, the aforementioned connectors 5 may be provided on at least both sides of the support frame 1 along its length.

[0130] This allows the entire fixing device to be connected to the circuit board 300 simply by connecting both ends of the support frame 1, making the operation convenient and the connection reliable.

[0131] Of course, connectors 5 can also be installed in the middle or other areas of the support frame 1.

[0132] Continue to refer to Figure 4 , Figure 11 and Figure 13 As shown, an intermediate connecting portion 16 is provided between two adjacent cavities 10, and a connector 5 can also be provided on the intermediate connecting portion 16.

[0133] By setting the intermediate connecting part 16, the overall structural strength of the support frame 1 is improved, thereby improving the structural strength of the entire fixing device.

[0134] By providing a connector 5 on the intermediate connection portion 16, the stability and reliability of the connection between the support frame 1 and the circuit board 300 are further improved, thereby further improving the stability of the support frame 1, and further improving the crimping effect of the crimping member 21 on the connector 200.

[0135] The connector fixing device 100 provided in this application embodiment can solve the problem of connector 200 floating and falling off due to insertion and extraction force or long-term use, for example, on high-density single boards, where fisheye connectors do not require additional screw holes on the connector 200 itself after crimping, thus ensuring the reliability of high-speed signals. This application embodiment also provides a circuit board assembly, including connector 200, circuit board 300, and connector fixing device 100.

[0136] The connector 200 has connecting terminals, such as fisheye terminals. The circuit board 300 has insertion holes, also known as conductive holes. The connecting terminals are crimped into the insertion holes, thereby achieving electrical connection between the connecting terminals and the circuit board 300. The connector 200 is fixed by the connector fixing device 100 to prevent the connector 200 from floating or falling off after crimping.

[0137] The connector fixing device 100 in this embodiment has the same specific structure and implementation principle as the connector fixing device 100 provided in the above embodiments, and can bring the same or similar technical effects.
