Description
Technical Field
[0001] This application relates to the field of FPC connector technology, and in particular to an FPC connector with foolproof positioning. Background Technology
[0002] Board-end connectors that electrically connect flexible printed circuit boards (FPCs) and printed circuit boards (PCBs) are suitable for applications with limited space and high vibration and shock, such as mobile phones, wearable devices, small home appliances, and automotive electronics.
[0003] However, most existing FPC connectors do not have a foolproof positioning structure. During the insertion of the FPC into the connector, the lack of a guiding structure to ensure that the FPC is inserted in the correct direction and position makes it easy for the FPC to be misaligned or misplaced, which increases the difficulty and error rate of the assembly operation. Utility Model Content
[0004] The purpose of this application is to provide an FPC connector with foolproof positioning, which has the advantage of preventing misalignment or displacement during FPC insertion. It solves the problem that in the existing FPC insertion process, due to the lack of a guiding structure to ensure that the FPC is inserted in the correct direction and position, misalignment or displacement is likely to occur during FPC insertion, which increases the difficulty of assembly operations and the error rate.
[0005] The FPC connector with anti-foolproof positioning provided in this application adopts the following technical solution: An FPC connector with anti-foolproof positioning includes a connector body, the connector body has multiple mounting slots arranged in a linear array inside, and gold fingers are fixedly connected inside each of the multiple mounting slots. Guide slots are fixedly connected to both sides of the inner wall of the connector body, and an anti-foolproof boss is fixedly connected to one side of the connector body. A first guide surface is provided on both sides of the inner wall of the anti-foolproof boss, and a second guide surface is provided on both the upper and lower sides of the anti-foolproof boss.
[0006] By adopting the above technical solution, multiple linearly arrayed mounting slots are opened inside the connector body, and gold fingers are fixedly connected in each mounting slot, providing a stable foundation for the conductive connection between the FPC and the connector. When the FPC is inserted, the corresponding contacts can make contact with the gold fingers, ensuring stable signal or current transmission. Furthermore, guide grooves are fixedly connected to both sides of the inner wall of the connector body, allowing the edge of the FPC to slide along the guide grooves during insertion, preventing misalignment and damage to the gold fingers or FPC. Finally, anti-misalignment bosses are provided, with first... The system includes a guide surface and second guide surfaces on the top and bottom sides. When an operator installs an FPC, only FPCs compatible with the anti-misalignment boss can be successfully inserted. If the FPC model is incorrect, the anti-misalignment boss will directly block the insertion, thus preventing the insertion of an incompatible FPC. The first and second guide surfaces further guide the FPC during correct installation, allowing it to adjust its position and be centered during insertion. This ensures smooth and precise docking of the FPC with the gold fingers, improving installation efficiency and reducing component damage caused by installation errors.
[0007] Preferably, a first rotating shaft is fixedly connected inside the connector body, a flip plate is rotatably provided on the outer wall of the first rotating shaft, support plates are fixedly connected on both sides of the flip plate, a plurality of springs arranged in a rectangular array are fixedly connected to the bottom end of the flip plate, and pressure plates are fixedly connected to the bottom ends of the plurality of springs.
[0008] By adopting the above technical solution, through the arrangement of the first rotating shaft, the flip plate, the spring, and the pressure plate, when it is necessary to install the FPC, the flip plate can be rotated around the first rotating shaft to open it, the FPC can be inserted into the corresponding position, and then the flip plate can be rotated in the opposite direction to reset it. At this time, the spring at the bottom of the flip plate will push the pressure plate to fit against the upper end of the FPC. The elasticity of the spring can prevent the pressure plate from causing hard squeezing damage to the FPC. At the same time, the pressure plate can keep the FPC in the correct position, so that the FPC contacts are in close contact with the gold fingers, preventing displacement during subsequent use, further ensuring the stability of the contact between the FPC and the gold fingers, and ensuring that signal or current transmission is not affected.
[0009] Preferably, a handle is fixedly connected to one side of the flip plate.
[0010] By adopting the above technical solution, a handle is fixedly connected to one side of the flip plate. When the flip plate needs to be rotated to install the FPC, the operator can easily lift the flip plate around the first axis by applying force through the handle.
[0011] Preferably, the connector body has two rotating grooves arranged in a mirror image on one side of the upper end. The bottom of the two rotating grooves is fixedly connected to a second rotating shaft. Both sides of the inner wall of the two rotating grooves are fixedly connected to protrusions. The outer walls of the two second rotating shafts are rotatably connected to claws. Both sides of the two claws are provided with grooves.
[0012] By adopting the above technical solution, through the setting of the rotating groove, the second rotating shaft and the cleaver, after the flip plate drives the pressure plate to press the FPC, the cleaver can be rotated to rotate around the second rotating shaft, so that the cleaver can engage with the upper end of the support plate of the flip plate, so that the cleaver can limit the flip plate, thereby ensuring that the pressure plate always presses the FPC tightly through the action of the spring, preventing the FPC from loosening. When it is necessary to remove the FPC, simply rotate the cleaver in the opposite direction to release the fixation of the flip plate.
[0013] Preferably, the flip plate is rotatably disposed inside the connector body.
[0014] By adopting the above technical solution, the flip plate can rotate around the first pivot inside the connector body. When it is necessary to install the FPC, the flip plate can be rotated to open the installation space inside the connector body, making it convenient for operators to place the FPC in the corresponding position of the installation slot.
[0015] Preferably, the two jaws are rotatably disposed inside the rotating groove, and the four protrusions are slidably disposed inside the groove.
[0016] By adopting the above technical solution, the claw can rotate flexibly around the second rotating shaft in the rotating groove. When the flip plate presses the FPC, the claw is rotated. When the claw rotates to fit with the support plate of the flip plate, the cooperation between the protrusion and the groove can fix the claw, thereby locking the support plate and preventing the flip plate from being lifted due to vibration or accidental contact during equipment operation. When it is necessary to disassemble the FPC, the claw is rotated in the opposite direction, and the protrusion is dislodged from the groove, so that the claw is freed from the restriction of the support plate, making it easy to lift the flip plate.
[0017] Preferably, the two claws are slidably disposed on the upper end of the support plate.
[0018] By adopting the above technical solution, two claws are slidably set on the upper part of the support plate. When the operator rotates the claws to the upper part of the support plate, the claws can block the support plate and prevent the flip plate from being lifted due to vibration or external force during equipment operation. When it is necessary to disassemble the FPC, the claws are rotated in the opposite direction to release the restriction on the support plate, and the flip plate can be easily lifted.
[0019] Preferably, the pressure plate is made of hard rubber.
[0020] By adopting the above technical solution, the pressure plate is made of hard rubber. Hard rubber has a certain degree of hardness to ensure that the FPC and the gold fingers are in close contact, avoiding poor local contact due to uneven pressure, and at the same time, it will not scratch the insulation layer on the surface of the FPC during the pressing process.
[0021] In summary, this application includes at least one of the following beneficial technical effects: This type of FPC connector with foolproof positioning improves installation efficiency and reduces component damage caused by installation errors through the design of guide grooves, foolproof bosses, flip plates, springs, and pressure plates. During installation, the foolproof boss on one side of the connector body, in conjunction with the first guide surfaces on both sides of its inner wall and the second guide surfaces on the top and bottom sides, allows only the compatible FPC to be inserted smoothly, avoiding damage caused by installation of incompatible models. At the same time, the first and second guide surfaces can further adjust the position of the FPC, and guide the FPC to be aligned by the guide groove on the inner wall, ensuring precise docking of the gold fingers in the mounting slot. After opening the flip plate, which rotates around the first axis, to place the FPC, the flip plate is then reset, and the spring at the bottom pushes the hard rubber pressure plate to fit the FPC. C. The elasticity of the spring prevents damage to the FPC from hard compression, while the hard rubber ensures uniform pressure transmission and tight contact between the FPC and the gold fingers, preventing the pressure plate from scratching the insulation layer of the FPC. Subsequently, the pawl, which rotates around the second axis in the rotating slot, slides along the upper end of the support plate and achieves limit positioning through the cooperation of the protrusion and the groove, locking the support plates on both sides of the flip plate. This prevents the flip plate from being lifted due to vibration or external force during equipment operation, and continuously ensures the clamping force of the pressure plate on the FPC. This device improves the efficiency of FPC installation, prevents damage caused by misalignment, and ensures the stability of the connection between the FPC and the gold fingers through the setting of the flip plate, spring, and pressure plate, reducing failures caused by incorrect installation or loose use, and extending the service life of the connector and FPC.

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.
[0025] Example 1: An FPC connector with foolproof positioning, refer to Figure 1 , Figure 2 and Figure 3 The connector body 1 includes a connector body 1 with multiple mounting slots 2 arranged in a linear array inside. Gold fingers 3 are fixedly connected to each mounting slot 2. By creating multiple mounting slots 2 in a linear array inside the connector body 1 and fixing gold fingers 3 in each slot 2, a stable foundation is provided for the conductive connection between the FPC and the connector. When the FPC is inserted, the corresponding contacts can make contact with the gold fingers 3, ensuring stable signal or current transmission. Guide grooves 4 are fixedly connected to both sides of the inner wall of the connector body 1. During the insertion of the FPC, its edge can slide along the guide grooves 4, preventing misalignment during insertion and thus avoiding damage to the gold fingers 3 or the FPC. A foolproof boss 5 is fixedly connected to one side of the connector body 1. The inner wall has a first guide surface 6 on both sides, and the anti-foolproof boss 5 has a second guide surface 7 on both the upper and lower sides. By setting the anti-foolproof boss 5 and setting the first guide surface 6 on both sides of the inner wall of the anti-foolproof boss 5 and the second guide surface 7 on the upper and lower sides, when the operator installs the FPC, only the FPC that is compatible with the anti-foolproof boss 5 can be successfully inserted. If the FPC model is incorrect, the anti-foolproof boss 5 will directly block the insertion action, thereby preventing the insertion of an incompatible FPC. The first guide surface 6 and the second guide surface 7 can further guide the FPC during correct installation, allowing it to adjust its position through the guidance of the first guide surface 6 and the second guide surface 7, so that the FPC is centered when inserted, allowing the FPC to smoothly and accurately align with the gold finger 3, thereby improving installation efficiency and reducing component damage caused by installation errors.
[0026] Example 2: An FPC connector with foolproof positioning, refer to Figure 1 , Figure 2 and Figure 4The connector body 1 has a first rotating shaft 8 fixedly connected inside. A flip plate 9 is rotatably mounted on the outer wall of the first rotating shaft 8. Support plates 10 are fixedly connected to both sides of the flip plate 9. Multiple springs 11 arranged in a rectangular array are fixedly connected to the bottom of the flip plate 9. Pressure plates 12 are fixedly connected to the bottom of the multiple springs 11. With the arrangement of the first rotating shaft 8, the flip plate 9, the springs 11, and the pressure plates 12, when it is necessary to install the FPC, the flip plate 9 can be rotated around the first rotating shaft 8 to open it, the FPC can be inserted into the corresponding position, and then the flip plate 9 can be rotated in the opposite direction to reset it. At this time, the springs 11 at the bottom of the flip plate 9 will push the pressure plates 12 to adhere. The spring 11, attached to the top of the FPC, prevents the pressure plate 12 from causing hard compression damage to the FPC. At the same time, the pressure plate 12 keeps the FPC in the correct position, ensuring that the FPC contacts are in close contact with the gold fingers 3, preventing displacement during subsequent use, and further ensuring the stability of the contact between the FPC and the gold fingers 3, ensuring that signal or current transmission is not affected. A handle 13 is fixedly connected to one side of the flip plate 9. When the flip plate 9 needs to be rotated to install the FPC, the operator can apply force through the handle 13 to easily lift the flip plate 9 around the first pivot 8.
[0027] Reference Figure 1 , Figure 2 and Figure 5 Two mirror-distributed rotating grooves 14 are provided on the upper side of one side of the connector body 1. The bottom of the two rotating grooves 14 is fixedly connected to a second rotating shaft 15. Both sides of the inner wall of the two rotating grooves 14 are fixedly connected to protrusions 16. The outer walls of the two second rotating shafts 15 are rotatably connected to claws 17. Both sides of the claws 17 are provided with grooves 18. Through the arrangement of the rotating grooves 14, the second rotating shafts 15 and the claws 17, when the flip plate 9 drives the pressure plate 12 to press the FPC, the claws 17 can be rotated to rotate around the second rotating shafts 15, so that the claws 17 can engage with the upper end of the support plate 10 of the flip plate 9, so that the claws 17 can limit the flip plate 9, thereby ensuring that the pressure plate 12 always presses the FPC tightly through the force of the spring 11, preventing the FPC from loosening. When it is necessary to remove the FPC, simply rotate the claws 17 in the opposite direction to release the fixation of the flip plate 9.
[0028] Reference Figure 1 , Figure 2 and Figure 4 The flip plate 9 is rotatably disposed inside the connector body 1. The flip plate 9 can rotate around the first rotating shaft 8 inside the connector body 1. When it is necessary to install the FPC, the flip plate 9 can be rotated to open the installation space inside the connector body 1, making it convenient for the operator to place the FPC into the corresponding position of the mounting slot 2.
[0029] Reference Figure 1 , Figure 2 and Figure 5Two claws 17 are rotatably mounted inside the rotating groove 14, and four protrusions 16 are slidably mounted inside the recess 18. The claws 17 can rotate flexibly around the second rotating shaft 15 within the rotating groove 14. When the flip plate 9 presses the FPC, rotating the claws 17 until they are in contact with the support plate 10 of the flip plate 9, the engagement of the protrusions 16 and the recess 18 can fix the claws 17, thereby locking the support plate 10 and preventing the flip plate 9 from lifting due to vibration or accidental contact during equipment operation. When it is necessary to disassemble the FPC, the flip plate 9 is rotated in the opposite direction. The claws 17 and protrusions 16 disengage from the grooves 18, allowing the claws 17 to release their restriction on the support plate 10, making it easier to lift the flip plate 9. The two claws 17 are slidably set on the upper end of the support plate 10. When the operator rotates the claws 17 to the upper end of the support plate 10, the claws 17 will block the support plate 10, preventing the flip plate 9 from being lifted due to vibration or external force during equipment operation. When it is necessary to disassemble the FPC, the claws 17 are rotated in the opposite direction to release the restriction on the support plate 10, and the flip plate 9 can be easily lifted.
[0030] Reference Figure 4 The pressure plate 12 is made of hard rubber. The hard rubber has a certain degree of hardness to ensure that the FPC and the gold fingers 3 are in close contact, avoiding poor local contact due to uneven pressure. At the same time, it will not scratch the insulation layer on the surface of the FPC during the pressing process.
[0031] The implementation principle of this application embodiment is as follows: During installation, the operator lifts the flip plate 9, which rotates around the first pivot 8 inside the connector body 1, and aligns the FPC with the anti-fooling boss 5 on one side of the connector body 1. At this time, the anti-fooling boss 5 only allows the compatible FPC to enter. If the FPC model is not compatible, the anti-fooling boss 5 will directly block its insertion. During the insertion process, the compatible FPC will be further guided by the first guide surface 6 on both sides of the inner wall of the anti-fooling boss 5 and the second guide surface 7 on the upper and lower sides to adjust its position, so that the FPC remains centered during insertion. During the insertion process, the edge will slide along the guide groove 4 on both sides of the inner wall of the connector body 1, accurately aligning with the gold fingers 3 arranged in a linear array inside the connector body 1, ensuring that the contacts of the FPC make initial contact with the gold fingers 3 fixed in the mounting groove 2. After the FPC is placed in place, the operator rotates the flip plate 9 in the opposite direction to reset it. The spring 11 at the bottom of the flip plate 9 pushes the pressure plate 12 to fit tightly against the upper end of the FPC. Since the pressure plate 12 is made of hard rubber, it can evenly transmit the pressing force of the spring 11 to the surface of the FPC, so that the FPC contacts and the gold fingers 3 fit tightly to ensure stable signal or current transmission. Then, the operator rotates the claw 17 in the rotating groove 14 at the upper end of one side of the connector body 1. The claw 17 will rotate around the second rotating shaft 15 at the bottom of the rotating groove 14 and move to the upper end of the support plates 10 on both sides of the flip plate 9 and fit against the support plates 10. At this time, the cooperation of the protrusion 16 and the groove 18 will fix the claw 17 in this position. The movement of the flip plate 9 is restricted by the claw 17 to prevent the flip plate 9 from being lifted due to vibration or accidental contact during the operation of the equipment, thereby ensuring that the pressure plate 12 always presses the FPC tightly by the force of the spring 11. When the FPC needs to be disassembled, the operator only needs to rotate the jaw 17 in the opposite direction to disengage the grooves 18 on both sides of the jaw 17 from the restriction of the protrusion 16, thereby releasing the jaw 17 from the obstruction of the support plate 10. Then, by lifting the flip plate 9 with the handle 13, the FPC can be removed from the connector body 1, realizing the precise installation, stable fixation and convenient disassembly of the FPC.
