Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically a flexible circuit board that is easy to install on one side. Background Technology

[0002] Flexible printed circuit boards (FPCBs) are a fundamental component of electronic products; every electronic product requires FPCBs. Then, within these products, FPCBs must be connected to other devices—this is known as FPCB interconnection. In the connection process between circuit boards and FPCBs, suitable for small instruments, pins are used to connect the circuit boards and FPCBs. This connection method is generally either parallel or perpendicular.

[0003] For example, a flexible circuit board that is easy to install in the prior art, with the publication number CN218602837U, uses a pressure block to insulate and press-fit the joint, thereby improving the stability of the connection between the first pin and the second pin.

[0004] However, in the aforementioned prior art, the fasteners are fixed on the circuit board, which means that the flexible circuit board can only be connected to the circuit board with the fasteners. At the same time, since the fasteners cannot be removed from the circuit board, the circuit board is easily damaged during maintenance when there is a fault in the fasteners, resulting in increased costs. Utility Model Content

[0005] The purpose of this invention is to provide a flexible circuit board that is easy to install on one side, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flexible circuit board for convenient single-sided installation, comprising a flexible circuit board, a circuit board, and a docking assembly. The docking assembly is disposed between the flexible circuit board and the circuit board. The sidewall of the flexible circuit board is provided with a plurality of first pins, and the sidewall of the circuit board is provided with a plurality of second pins that match the first pins. The docking assembly includes a docking member, which has a fixing hole. A lower pressure plate and an arc-shaped pressure block are disposed in the fixing hole. Three elastic cylinders are fixedly connected to the upper end of the docking member. A return spring is fixedly installed in each of the three elastic cylinders. A connecting plate is fixedly connected to the lower end of each of the three return springs. An upper connecting rod is fixedly connected to the upper end of each of the three connecting plates. A lower connecting rod is fixedly connected to the lower end of each of the three connecting plates. A lifting plate is fixedly connected to the upper end of each of the three upper connecting rods. The lower ends of each of the three lower connecting rods are fixedly connected to the upper end of the lower pressure plate. The operator manually pulls the lifting plate upwards, causing it to drive three return springs and compress the three lower connecting rods upwards. At this time, the three lower connecting rods move upwards synchronously and together pull the lower pressure plate and arc-shaped pressure block in the fixing hole upwards so that their upper ends abut against the upper end of the inner wall of the fixing hole. Then, the first pin of the flexible circuit board and the second pin of the circuit board are inserted into each other in the fixing hole of the docking part. Then, the lifting plate is released to reset the three lower connecting rods and push the lower connecting rods downwards. The three lower connecting rods move downwards and push the lower pressure plate and arc-shaped pressure block against the connection between the first pin and the second pin, thereby ensuring the stability of the connection between the flexible circuit board and the circuit board. At the same time, since the docking part is slidably set between the flexible circuit board and the circuit board, the components inside the docking part can be detached from the flexible circuit board and the circuit board and replaced and maintained externally. This can effectively avoid accidental damage to the circuit board during maintenance. The flexible circuit board and the circuit board have been fully disclosed in publication number CN218602837U and will not be described again here.

[0007] Preferably, the circuit board has two side holes on its sidewall, which are slidably connected to the inner wall of the fixing hole and the sidewall of the mating component, respectively. By providing these side holes, the mating assembly can be slidably mounted on the circuit board, facilitating subsequent replacement and maintenance of the internal components by the operator and preventing accidental damage to the circuit board during maintenance, thus avoiding increased operating costs.

[0008] Preferably, the sidewalls of the three upper connecting rods are slidably connected to the inner walls of the three elastic cylinders. By making the sidewalls of the three upper connecting rods slidably connected to the inner walls of the three elastic cylinders, the upper connecting rods can slide and rise vertically against the inner walls of the elastic cylinders.

[0009] Preferably, the three connecting plates and the three lower connecting rods are slidably connected to the inner walls of the three elastic cylinders, respectively. By making the connecting plates and lower connecting rods slidably connected to the inner walls of the elastic cylinders, the connecting plates and lower connecting rods can slide and move up and down along the inner walls of the elastic cylinders.

[0010] Preferably, the arc-shaped pressure block is an arc-shaped silicone block. By using an arc-shaped silicone block as the arc-shaped pressure block, when it contacts the mating points of multiple first and second pins, it can ensure the downward pressure and fixation of the mating points while reducing damage to the first and second pins at the mating points.

[0011] Preferably, the diameter of the fixing hole is slightly larger than the size of one side of the flexible circuit board. By making the diameter of the fixing hole slightly larger than the size of one side of the flexible circuit board, the flexible circuit board can insert the side with multiple first pins into the fixing hole and connect with multiple second pins.

[0012] Preferably, the length of the lower pressure plate and the arc-shaped pressure block is slightly greater than the length of the first pin and the second pin after they are joined. By making the length of the lower pressure plate and the arc-shaped pressure block slightly greater than the length of the first pin and the second pin after they are joined, the lower pressure plate and the arc-shaped pressure block can cover the joints of multiple first pins and second pins, ensuring complete coverage and fixation of the joints.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This invention features a docking component that is positioned between the flexible circuit board and the circuit board. This allows the docking component to be removed from between the flexible circuit board and the circuit board when maintenance or replacement is required, effectively preventing accidental damage to the circuit board during maintenance and thus avoiding increased usage costs.

[0015] This invention uses an arc-shaped pressure block as an arc-shaped silicone block. When the arc-shaped pressure block presses and fixes the joint formed by multiple first and second pins, the silicone block can reduce the damage to the surface of the first and second pins during pressing, reduce the wear on the first and second pins after fixing, and effectively extend the service life of the first and second pins.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1:

[0023] like Figures 1-4 As shown, this utility model proposes a flexible circuit board for convenient single-sided installation, including a flexible circuit board 1, a circuit board 2, and a docking assembly. The docking assembly is disposed between the flexible circuit board 1 and the circuit board 2. The side wall of the flexible circuit board 1 is provided with a plurality of first pins 3, and the side wall of the circuit board 2 is provided with a plurality of second pins 4 that match the first pins 3. The docking assembly includes a docking member 6, which has a fixing hole 8. A lower pressure plate 13 and an arc-shaped pressure block 14 are disposed in the fixing hole 8. Three elastic cylinders 7 are fixedly connected to the upper end of the docking member 6. A return spring 10 is fixedly installed in each of the three elastic cylinders 7. A connecting plate is fixedly connected to the lower end of each of the three return springs 10. An upper connecting rod 9 is fixedly connected to the upper end of each of the three connecting plates. A lower connecting rod 12 is fixedly connected to the lower end of each of the three upper connecting rods 9. A lifting plate 11 is fixedly connected to the upper end of each of the three lower connecting rods 12. The lower end of each of the three lower connecting rods 12 is fixedly connected to the upper end of the lower pressure plate 13.

[0024] The working principle of a single-sided, conveniently installed flexible circuit board based on Embodiment 1 is as follows: First, the operator manually pulls the lifting plate 11 upwards, causing the lifting plate 11 to drive three return springs 10 and compress the three lower connecting rods 12 upwards respectively. At this time, the three lower connecting rods 12 move upwards synchronously and together pull the lower pressure plate 13 and the arc-shaped pressure block 14 in the fixing hole 8 upwards so that their upper ends abut against the upper end of the inner wall of the fixing hole 8. Then, the first pin 3 of the flexible circuit board 1 and the second pin 4 of the circuit board 2 are inserted into each other in the fixing hole 8 of the mating part 6. Releasing the lifting plate 11 resets the three lower connecting rods 12 and pushes them downwards. The three lower connecting rods 12 move downwards and push the lower pressure plate 13 and the arc-shaped pressure block 14 against the connection between the first pin 3 and the second pin 4, thereby ensuring the stability of the connection between the flexible circuit board 1 and the circuit board 2. At the same time, since the docking part 6 is slidably set between the flexible circuit board 1 and the circuit board 2, the components inside the docking part 6 can be detached from the flexible circuit board 1 and the circuit board 2 and replaced and maintained from the outside, which can effectively avoid accidental damage to the circuit board 2 during maintenance.

[0025] Example 2:

[0026] like Figures 1-4 As shown, the present invention proposes a flexible circuit board for convenient single-sided installation. Compared with Embodiment 1, this embodiment further includes: two side holes 5 are opened on the side wall of the circuit board 2, the two side holes 5 are slidably connected to the inner wall of the fixing hole 8 and the side wall of the docking piece 6 respectively; the side walls of the three upper connecting rods 9 are slidably connected to the inner walls of the three elastic cylinders 7 respectively; the three connecting plates and the three lower connecting rods 12 are slidably connected to the inner walls of the three elastic cylinders 7 respectively; the arc-shaped pressure block 14 is an arc-shaped silicone block; the diameter of the fixing hole 8 is slightly larger than the size of one side of the flexible circuit board 1; the length of the lower pressure plate 13 and the arc-shaped pressure block 14 is slightly larger than the length of the first pin 3 and the second pin 4 after docking.

[0027] In this embodiment, as Figure 4 As shown, by opening the side hole 5, the docking assembly can be slidably mounted on the circuit board 2, facilitating subsequent replacement and maintenance of the internal components of the docking assembly by the operator, and avoiding accidental damage to the circuit board 2 during maintenance, which would increase the operating cost. By slidably connecting the side walls of the three upper connecting rods 9 to the inner walls of the three elastic cylinders 7 respectively, the upper connecting rods 9 can slide vertically up and down against the inner wall of the elastic cylinder 7. By slidably connecting the connecting plate and the lower connecting rod 12 to the inner wall of the elastic cylinder 7, the connecting plate and the lower connecting rod 12 can slide up and down along the inner wall of the elastic cylinder 7. By making the arc-shaped pressure block 14 an arc-shaped silicone block, the arc-shaped pressure block 14 can be connected to the... When contacting the joints of multiple first pins 3 and second pins 4, the pressure and fixation of the joints are ensured while reducing damage to the first pins 3 and second pins 4. By making the diameter of the fixing hole 8 slightly larger than the size of one side of the flexible circuit board 1, the side of the flexible circuit board 1 with multiple first pins 3 can be inserted into the fixing hole 8 and connected with multiple second pins 4. By making the length of the pressure plate 13 and the arc-shaped pressure block 14 slightly larger than the length of the first pins 3 and second pins 4 after connection, the pressure plate 13 and the arc-shaped pressure block 14 can cover the joints of multiple first pins 3 and second pins 4, ensuring complete pressure and fixation of the joints.

[0028] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
