Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and more particularly to a double-sided flip-up FPC fixing fixture. Background Technology

[0002] FPC, short for Flexible Printed Circuit, is a printed circuit made of a flexible insulating substrate. FPC offers excellent electrical performance, meeting the design needs for smaller and higher-density installations, and also helps reduce assembly steps and enhance reliability. FPC is the only solution to meet the miniaturization and mobility requirements of electronic products; it can be freely bent, rolled, and folded, and can withstand millions of dynamic bends without damaging the wires. It can be arranged arbitrarily according to spatial layout requirements and can move and stretch freely in three-dimensional space, thus achieving integration of component assembly and wire connection. FPC can significantly reduce the size and weight of electronic products, meeting the needs of electronic products developing towards high density, miniaturization, and high reliability.

[0003] In the production and processing process, it is often necessary to use a fixture to unfold and fix the FPC before further fixing the fixture and the FPC in the processing equipment for high-precision production, processing, and testing. However, most existing FPC fixtures do not have a dedicated flipping function structure, making it difficult to easily and efficiently flip FPCs that require double-sided processing and testing. Utility Model Content

[0004] Therefore, it is necessary to provide a double-sided flip-up FPC fixing fixture to address the shortcomings of the existing technology.

[0005] A reversible FPC fixing fixture includes an outer frame, an inner frame, and two sets of clamping members. The inner frame is located inside the outer frame, and the two sets of clamping members are respectively installed on the inner side of the inner frame and are arranged opposite to each other. Each clamping member includes a through rod and an elastic clamp. The through rod passes horizontally through the outer frame and the inner frame in sequence, with its two ends extending to the outer side of the outer frame and the inner side of the inner frame, respectively. The through rod can also rotate relative to the outer frame, and the elastic clamp is integrally formed on the inner end of the through rod.

[0006] Furthermore, the inner frame is equipped with a clamping rod, a sliding rod, and a telescopic spring. The two ends of the clamping rod are integrally connected to the front and rear inner sidewalls of the inner frame, respectively. The clamping rod also has a through-hole extending from left to right. The two ends of the sliding rod are integrally connected to one side of the clamping rod and the left or right inner wall of the inner frame, respectively. The sliding rod and the clamping rod are arranged perpendicularly to each other. The telescopic spring is sleeved on the sliding rod. The elastic clamping device is installed in the clamping through-hole and passes through the sliding rod, receiving elastic support from the telescopic spring.

[0007] Furthermore, the elastic clamp includes a clamping seat, a lower clamping plate, and an upper clamping plate. The clamping seat is fitted into the clamping through hole and passes through the sliding rod. The clamping seat can slide left and right along the clamping through hole. The lower clamping plate is integrally formed on one side of the clamping seat. The upper clamping plate is elastically connected to one side of the clamping seat and is arranged vertically opposite to the lower clamping plate.

[0008] Furthermore, the clamping rod is also equipped with an adjusting block and an adjusting bolt, and the clamping through hole is designed to be open on both sides and at the top. The adjusting block is installed on the clamping rod from top to bottom and is located at the top opening of the clamping through hole. The adjusting bolt passes through the adjusting block and the clamping rod and can be rotated for adjustment.

[0009] Furthermore, one side of the bottom of the adjustment block is designed with rounded corners.

[0010] Furthermore, the inner frame is also provided with a locking piece, which is locked onto the sliding rod and abuts against one end of the telescopic spring.

[0011] Furthermore, the outer frame is also provided with a limiting rod and a limiting spring, and the inner frame is provided with a corresponding limiting hole. The limiting rod passes through the outer frame and its two ends extend to the inner and outer sides of the outer frame, respectively. The limiting spring is sleeved on the limiting rod. The inner end of the limiting rod can pass through the limiting hole to limit and fix the outer frame and the inner frame.

[0012] In summary, the beneficial effects of this utility model's double-sided flip-up FPC fixing fixture are as follows: By designing a flip-up clamping structure, the FPC can be easily flipped for double-sided processing after being fixed in the fixture, greatly improving the ease of use of the FPC fixing fixture in double-sided processing and testing applications; the inner frame's elastic sliding structure, combined with the clamping components, can clamp FPCs of different lengths and ensure that the clamped FPC is completely flattened; the clamping rod's adjustable structure, combined with the clamping components, can clamp FPCs of different thicknesses; and the limiting structure on the outer frame effectively prevents the FPC from accidentally flipping or shifting during processing or testing. This utility model is highly practical and has significant potential for widespread application. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0019] like Figures 1 to 5 As shown, this utility model provides a double-sided flip-up FPC fixing fixture 100, which includes an outer frame 10, an inner frame 20 and two sets of clamping members 30. The inner frame 20 is disposed inside the outer frame 10, and the two sets of clamping members 30 are respectively installed on the inner side of the inner frame 20 and are arranged opposite to each other.

[0020] The clamping member 30 includes a through rod 31 and an elastic clamp 32. The through rod 31 passes horizontally through the outer frame 10 and the inner frame 20 in sequence, with its two ends extending to the outer side of the outer frame 10 and the inner side of the inner frame 20, respectively. The through rod 31 can also rotate relative to the outer frame 10. The elastic clamp 32 is integrally provided on the inner end of the through rod 31. When the FPC is clamped by the elastic clamp 32, the inner frame 20, the clamping member 30, and the FPC can be rotated synchronously by rotating the through rod 31, thereby easily realizing double-sided flipping processing or testing of the FPC.

[0021] The inner frame 20 is equipped with a clamping rod 21, a sliding rod 22, and a telescopic spring 23. The two ends of the clamping rod 21 are integrally connected to the front and rear inner side walls of the inner frame 20, respectively. The clamping rod 21 also has a through-hole 211 extending from left to right. The two ends of the sliding rod 22 are integrally connected to one side of the clamping rod 21 and the left or right inner wall of the inner frame 20, respectively. The sliding rod 22 is perpendicular to the clamping rod 21. The telescopic spring 23 is sleeved on the sliding rod 22. The elastic clamp 32 is engaged within the clamping through-hole 211 and passes through the sliding rod 22, receiving elastic support from the telescopic spring 23.

[0022] When the elastic clips 32 clamp and fix the FPC, the telescopic spring 23 can drive the elastic clips 32 on both sides to slide outwards respectively, thereby causing the clamped FPC to be flattened by an outward pulling force. This ensures that the FPC will not be affected by factors such as curling or wrinkling during processing or testing. Moreover, the telescopic and sliding elastic clips 32 can also accommodate FPCs of different lengths, greatly expanding the applicability of the fixture.

[0023] The inner frame 20 also includes a locking tab 24, which is engaged with the sliding rod 22 and abuts against one end of the telescopic spring 23. The locking tab 24 can compress the length of the telescopic spring 23, thereby changing the elastic tension on the elastic clip 32 and the FPC. By engaging locking tabs 24 of different thicknesses on the sliding rod 22, the elastic force of the telescopic spring 23 can be adjusted, thus optimizing the tension on the FPC. This avoids the problem of insufficient tension preventing the FPC from flattening, while also preventing excessive tension from causing the FPC to crack or even break.

[0024] The elastic clamp 32 includes a clamping seat 321, a lower clamping plate 322, and an upper clamping plate 323. The clamping seat 321 is fitted into the clamping through hole 211 and passes through the sliding rod 22. The clamping seat 321 can slide left and right along the clamping through hole 211. The lower clamping plate 322 is integrally formed on one side of the clamping seat 321. The upper clamping plate 323 is elastically connected to one side of the clamping seat 321 and is arranged vertically opposite to the lower clamping plate 322.

[0025] When a pushing force is applied to the outer end of the inserting rod 31, the clamping seat 321 slides inward toward the clamping through hole 211. When the lower clamping plate 322 and the upper clamping plate 323 extend out of the clamping through hole 211, the upper clamping plate 323, which is elastically connected to the clamping seat 321, will remain open under the action of elastic force. At this time, the end of the FPC can be placed between the lower clamping plate 322 and the upper clamping plate 323. Then, the pushing force applied to the inserting rod 31 is removed, and the telescopic spring 23 will drive the lower clamping plate 322 and the upper clamping plate 323 to retract into the clamping through hole 211. At this time, under the constraint of the clamping through hole 211, the upper clamping plate 323 and the lower clamping plate 322 will clamp and fix the end of the FPC.

[0026] The clamping rod 21 is also equipped with an adjusting block 212 and an adjusting bolt 213. The clamping through hole 211 is designed with openings on both sides and the top. The adjusting block 212 is mounted on the clamping rod 21 from top to bottom and is located at the top opening of the clamping through hole 211. The adjusting bolt 213 passes through the adjusting block 212 and the clamping rod 21 and can be rotated for adjustment. One bottom edge of the adjusting block 212 is rounded. The structure of the adjusting block 212 and the adjusting bolt 213 on the clamping rod 21 can be coordinated to adjust the height of the clamping through hole 211, thereby enabling the clamping through hole 211 to clamp and fix FPCs of different thicknesses to the elastic clamp 32.

[0027] The outer frame 10 is also provided with a limiting rod 11 and a limiting spring 12, and the inner frame 20 is provided with a corresponding limiting hole 25. The limiting rod 11 passes through the outer frame 10 and its two ends extend to the inner and outer sides of the outer frame 10, respectively. The limiting spring 12 is sleeved on the limiting rod 11. The inner end of the limiting rod 11 can pass through the limiting hole 25 to limit and fix the outer frame 10 and the inner frame 20. The limiting structure on the outer frame 10 can flexibly limit the outer frame 10 and the inner frame 20. When it is necessary to flip the FPC, the limiting rod 11 can be pulled to release the limit and allow the inner frame 20 and the FPC inside it to flip relative to the outer frame 10. When the FPC is processed or tested, the limiting rod 11 can keep the inner frame 20 and the outer frame 10 relatively fixed to prevent the FPC from rotating or deviating.

[0028] In summary, the beneficial effects of this utility model's double-sided flip-up FPC fixing fixture 100 are as follows: by designing a flip-up clamping structure, the FPC can be easily flipped for double-sided processing after being fixed by the fixture, greatly improving the ease of use of the FPC fixing fixture in double-sided processing and testing application scenarios; the inner frame 20 is designed with an elastic sliding structure, which, together with the clamping component 30, can clamp FPCs of different lengths and ensure that the clamped FPC is completely flat; the clamping rod 21 is designed with an adjustment structure, which, together with the clamping component 30, can clamp FPCs of different thicknesses; and the limiting structure on the outer frame 10 can effectively prevent the FPC from accidentally flipping or shifting during processing or testing; this utility model is highly practical and has strong promotional significance.

[0029] The embodiments described above illustrate only one implementation of the utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be determined by the appended claims.
