Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and particularly relates to a damage-proof FPC connector. Background Art

[0002] With the trend of thinning of electronic products, the internal space is becoming increasingly compact, which poses higher requirements for the design of electronic components. Especially in the display screen industry, as an important connecting component between the screen and the main board, the stability and durability of the FPC (Flexible Printed Circuit) connector directly affect the functional performance and service life of the entire electronic device. Although the common FPC connectors on the market can meet the basic connection requirements, in the actual production and use process, due to their structural characteristics, they are easily affected by external pressure, resulting in increasingly prominent problems such as performance degradation or even failure.

[0003] In the production and application scenarios of FPC connectors, in order to reduce the risk of damage, a support structure is added around the connector to disperse external forces; a more flexible material is selected to make the FPC to enhance its flexibility; the interface design is optimized. However, although this plugging and unplugging method is easy to operate, the connection stability is poor and there is a lack of necessary protection, which is extremely likely to have a negative impact on the stability and safety of the connection, and then lead to abnormal signal transmission, seriously affecting the reliability and data transmission quality of the FPC connector in actual use.

[0004] Therefore, it is necessary to provide a damage-proof FPC connector to solve the above problems. Summary of the Invention

[0005] The main purpose of the present invention is to provide a damage-proof FPC connector, which can effectively solve the problems in the background art.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is as follows: A damage-proof FPC connector includes a connection head, a positioning seat, a conveying line and a fixing seat. The connection head and the conveying line are fixedly connected. A docking component is arranged inside the positioning seat, and the docking component includes a clamping mechanism, a control mechanism, a locking mechanism and an installation mechanism; The clamping mechanism includes movable plates symmetrically and slidably connected inside the positioning seat. On the side where the two movable plates are close to each other, there are clamping seats slidably connected. On the outer sides of the two clamping seats, there are connecting plates symmetrically and slidably connected. Between the movable plates and the inner wall of the positioning seat, there are symmetrically and fixedly connected first springs. Between the connecting plates and the inner wall of the positioning seat, there are fixedly connected second springs; The installation mechanism includes connection seats and alloy elastic pieces symmetrically arranged on the outside of the connection head. The connection seats are fixedly connected to the connection head, and the alloy elastic pieces are fixedly connected inside the connection seats. The alloy elastic pieces are in a wavy structure.

[0007] As a further improvement of the above solution, the control mechanism includes connection sleeves symmetrically and fixedly connected to the outside of the movable plate. The connection sleeves are divided into two groups with two in each group. Inside each of the two connection sleeves in each group, a movable seat is slidably connected. An installation shaft is fixedly connected inside each of the connection sleeves. A push plate is rotatably connected between the movable seat and the installation shaft.

[0008] As a further improvement of the above solution, the locking mechanism includes movable sleeves symmetrically slidably connected inside the positioning seat. The movable sleeves are fixedly connected to the movable seats. Fixed blocks are symmetrically and fixedly connected to the outside of the fixed seat. Inside the positioning seat, threaded rods are symmetrically rotatably connected. At one end of the threaded rod located outside the positioning seat, a gear is fixedly connected. The other end of the threaded rod is threadedly connected to a movable block. The movable block is slidably connected to the inside of the positioning seat and the movable seat. One end inner wall of the fixed block meshes with the gear.

[0009] As a further improvement of the above solution, the clamping mechanism further includes limiting rods symmetrically and fixedly connected inside the positioning seat. The connecting plate is slidably connected to the outside of the limiting rods. The second spring is sleeved on the outside of the limiting rods.

[0010] As a further improvement of the above solution, the inner wall of the clamping seat is provided with a wavy groove adapted to the alloy elastic sheet. The alloy elastic sheet is slidably connected inside the wavy groove.

[0011] As a further improvement of the above solution, a connecting block is fixedly connected to the outside of the movable block. On the side of the connecting block away from the threaded rod, clamping blocks are symmetrically and fixedly connected. On the inner walls of the connection sleeves, clamping grooves adapted to the clamping blocks are provided.

[0012] As a further improvement of the above solution, sliding seats are symmetrically slidably connected inside the positioning seat. Inside each of the sliding seats, a cleaning rod is rotatably connected. Spring threes are symmetrically and fixedly connected between the cleaning rod and the inner wall of the positioning seat.

[0013] As a further improvement of the above solution, a limiting groove is provided inside the positioning seat. The two sliding seats are symmetrically slidably connected inside the limiting groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Pressing the locking mechanism drives the clamping mechanism to separate under the action of the control mechanism, facilitating the insertion of the connector into the clamping mechanism. After releasing the pressing, the clamping mechanism fixedly clamps the connector. With the second spring in the clamping mechanism, a buffering effect is achieved, ensuring the use safety of the clamping mechanism after fixedly connecting the connector through the installation mechanism. When continuously pulling later, the connector can be disassembled through the installation mechanism, thus ensuring the stability and safety during the connection process.

[0015] 2. The movement of the movable sleeve causes the connecting sleeve to displace. The connecting sleeve drives the movable plate with the help of the push plate, and then separates the two clamping seats. After the clamping operation is completed, the positioning seat and the fixed seat are docked. At this time, the meshing connection between the fixed block and the gear plays a role, pushing the connecting block, thereby firmly fixing the position of the connecting sleeve, effectively ensuring the stability of the clamping process, providing a reliable and stable mechanical structure basis for related connection operations, ensuring that a stable connection state can still be maintained under complex working conditions and external force interference, and improving the reliability and durability of the overall connection system.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 9 As shown in the figure, the present invention provides an embodiment: an anti-damage FPC connector, including a connector 1, a positioning seat 2, a conveyor line 3 and a fixed seat 4. The connector 1 and the conveyor line 3 are fixedly connected. A docking assembly 5 is arranged inside the positioning seat 2. The docking assembly 5 includes a clamping mechanism 51, a control mechanism 52, a locking mechanism 53 and a mounting mechanism 54; The clamping mechanism 51 includes movable plates 512 symmetrically and slidably connected inside the positioning seat 2. On the side where the two movable plates 512 are close to each other, clamping seats 511 are slidably connected. On the outer sides of the two clamping seats 511, connecting plates 515 are symmetrically and slidably connected. Between the movable plates 512 and the inner wall of the positioning seat 2, first springs 513 are symmetrically and fixedly connected. Between the connecting plates 515 and the inner wall of the positioning seat 2, second springs 514 are fixedly connected; The mounting mechanism 54 includes connecting seats 541 and alloy spring pieces 542 symmetrically arranged outside the connector 1. The connecting seats 541 are fixedly connected to the connector 1. The alloy spring pieces 542 are fixedly connected inside the connecting seats 541. The alloy spring pieces 542 are in a wavy structure.

[0021] In practical applications of the embodiments of the present invention, the connector 1 is fixedly connected to the conveyor line 3. When docking operations are performed, the locking mechanism 53 drives the control mechanism 52 to operate, causing the movable plate 512 in the clamping mechanism 51 to slide symmetrically inside the positioning seat 2. The sliding of the movable plate 512 drives the corresponding displacement of the clamping seat 511 on the side close to it. At the same time, the connecting plate 515 outside the clamping seat 511 also slides between the inner walls of the positioning seat 2. During this process, the first spring 513 and the second spring 514 respectively produce elastic deformations to achieve the functions of buffering and resetting, so that the clamping seat 511 can adapt to connectors 1 of different sizes and achieve stable clamping. The connecting seat 541 on the outside of the connector 1 and the corrugated alloy elastic sheet 542 fixed inside it utilize the elasticity and special structure of the alloy elastic sheet 542 to further enhance the stability and reliability of the connector 1 after installation, effectively preventing connection loosening or damage caused by external forces and other factors, and ensuring the stable operation of the FPC connector during data transmission and other operations.

[0022] As Figure 2 , Figure 5 and Figure 6 shown, the control mechanism 52 includes connecting sleeves 521 symmetrically and fixedly connected to the outside of the movable plate 512. The connecting sleeves 521 are divided into two groups in groups of two. Inside each group of two connecting sleeves 521, a movable seat 522 is slidably connected. An installation shaft 524 is fixedly connected inside each of the connecting sleeves 521. A push plate 523 is rotatably connected between the movable seat 522 and the installation shaft 524.

[0023] In practical applications of the embodiments of the present invention, the connecting sleeves 521 are symmetrically fixed to the outside of the movable plate 512 and are distributed in a specific grouping form. Inside the internal structure of each group of connecting sleeves 521, the movable seat 522 is slidably connected. At the same time, the installation shaft 524 is fixedly connected to it. It should be noted that a rotational connection relationship is established between the movable seat 522 and the installation shaft 524 through the push plate 523. When an external driving force is applied to this mechanism, the movable seat 522 can slide smoothly inside the connecting sleeve 521. During this process, with the help of the ingenious rotational transmission mechanism of the push plate 523, the sliding movement of the movable seat 522 can be effectively converted into a precise pushing and pulling force on the movable plate 512. Based on this conversion mechanism, the opening and closing actions of the clamping seat 511 in the clamping mechanism 51 can be precisely controlled, so as to successfully achieve the accurate docking and separation operations between the connector 1 and other components, ensuring the efficiency and accuracy of the entire connection process and meeting the strict requirements of relevant equipment or systems for connection stability and reliability.

[0024] As Figure 2 , Figure 5 and Figure 7As shown, the locking mechanism 53 includes a movable sleeve 531 symmetrically and slidably connected inside the positioning seat 2. The movable sleeve 531 is fixedly connected to the movable seat 522. Symmetrically and fixedly connected to the outside of the fixed seat 4 are fixed blocks 532. Inside the positioning seat 2, threaded rods 534 are symmetrically and rotatably connected. At one end of the threaded rod 534 located outside the positioning seat 2 is fixedly connected a gear 533. The other end of the threaded rod 534 is threadedly connected to a movable block 535. The movable block 535 is slidably connected to the inside of the positioning seat 2 and the movable seat 522. The inner wall of one end of the fixed block 532 meshes with the gear 533.

[0025] In the actual application of the embodiment of the present invention, during the docking operation, the movable sleeve 531 slides inside the positioning seat 2. Due to its fixed connection with the movable seat 522, it can accurately drive the movable seat 522 to move synchronously. At the same time, the fixed blocks 532 fixedly connected to the outside of the fixed seat 4 play a crucial role in the docking process of the positioning seat 2 and the fixed seat 4. Inside the internal structure of the positioning seat 2, the threaded rod 534 is rotatably connected. At one end of the threaded rod 534 located outside the positioning seat 2 is firmly fixedly connected a gear 533, and this gear 533 is in a tightly meshed connection state with the inner wall of one end of the fixed block 532. As the docking action continues to steadily progress, the fixed block 532 exerts a pushing force on the gear 533, causing the gear 533 to rotate. The rotation of the gear 533 further drives the connected threaded rod 534 to rotate synchronously. Given the specific threaded connection relationship between the threaded rod 534 and the movable block 535, and the structural design that the movable block 535 is slidably connected to the inside of the positioning seat 2 and the movable seat 522, when the threaded rod 534 rotates, it will drive the movable block 535 to generate a corresponding displacement change. In this way, it can effectively achieve the precise locking of the position of the movable seat 522, and further strongly ensure the structural stability of the clamping mechanism 51 after the docking operation is successfully completed. In this way, even in the face of accidental vibration or external force interference, it can still effectively prevent loosening of the connection, providing a solid and reliable guarantee for the reliable and stable operation of the FPC connector, enabling it to continuously and stably perform the connection function in various complex working condition environments, and meeting the strict requirements of relevant equipment or systems for connection accuracy and stability. As Figure 5 As shown, the clamping mechanism 51 further includes limit rods 516 symmetrically and fixedly connected inside the positioning seat 2. The connecting plate 515 is slidably connected to the outside of the limit rods 516. The second spring 514 is sleeved on the outside of the limit rods 516.

[0026] In the actual application of the embodiment of the present invention, with the help of the limiting rod 516, the stability of the connecting plate 515 during movement can be effectively guaranteed, preventing the second spring 514 from bending during the compression and reset processes, thereby maintaining the reliability and accuracy of the operation of the entire mechanism, ensuring the smooth progress of relevant connection and transmission actions, and avoiding problems such as connection failure or performance degradation caused by abnormal deformation of components.

[0027] As shown in the figure, a wavy groove adapted to the alloy elastic piece 542 is formed in the inner wall of the clamping seat 511, and the alloy elastic piece 542 is slidably connected in the wavy groove.

[0028] In the actual application of the embodiment of the present invention, by virtue of the wavy structure design of the alloy elastic piece 542, the stability of the docking between the clamping seat 511 and the alloy elastic piece 542 can be effectively guaranteed, enabling them to be closely matched to ensure the reliability of the connection. At the same time, under the action of a specific tensile force, this wavy structure can also prompt the separation of the docking between the clamping seat 511 and the alloy elastic piece 542, thereby meeting the separation requirements of the connector 1 and related components under specific working conditions or operation requirements, ensuring both the stability during connection and the flexibility and operability during separation, and enhancing the adaptability and functionality of the entire FPC connector in different working scenarios.

[0029] As Figure 7 shown, a connecting block 536 is fixedly connected to the outside of the movable block 535. Symmetrically fixed to the side of the connecting block 536 away from the threaded rod 534 are clamping blocks 537, and clamping grooves adapted to the clamping blocks 537 are formed on the inner walls of the connecting sleeves 521.

[0030] In the actual application of the embodiment of the present invention, the clamping blocks 537 provided at the bottom of the connecting block 536 can provide reliable guarantee for the fixation of the connecting sleeve 521 in the positioning seat 2, effectively enhancing the stability of its fixation. The clamping blocks 537 are closely matched with the corresponding structures inside the positioning seat 2 to form a stable limiting and supporting system, preventing the connecting sleeve 521 from shifting or shaking due to external interference factors, thereby ensuring that during the operation of the FPC connector, the connection relationship between relevant components always remains accurate and stable, maintaining the normal operation of the entire connection system, and avoiding problems such as data transmission interruption or connection failure caused by loose connection, and enhancing the reliability and durability of the product.

[0031] As Figure 8 shown, sliding seats 55 are symmetrically and slidably connected inside the positioning seat 2. Cleaning rods 57 are rotatably connected inside the sliding seats 55, and third springs 56 are symmetrically and fixedly connected between the cleaning rods 57 and the inner wall of the positioning seat 2.

[0032] In the actual application of the embodiments of the present invention, the sliding seat 55 drives the cleaning rod 57. With the elastic effect of the third spring 56, the cleaning operation of the connector can be efficiently performed. Under the action of the third spring 56, the cleaning rod 57 is closely attached to the surface of the connector, effectively removing the dust particles attached thereto, significantly reducing the adverse effects of dust on signal transmission, ensuring the stability and accuracy of signal transmission, maintaining the normal working performance of the FPC connector, and reducing problems such as signal interference, attenuation, and even interruption caused by dust accumulation, thereby improving the reliability of the entire connection system and the data transmission quality.

[0033] As Figure 8 shown, a limiting groove is provided inside the positioning seat 2, and two sliding seats 55 are symmetrically and slidably connected inside the limiting groove; In the actual application of the embodiments of the present invention, the limiting groove can accurately define the movement path of the sliding seat 55, effectively preventing the sliding seat 55 from deviating, shaking, or other unstable movement states during operation. Through the close cooperation with the sliding seat 55, the limiting groove provides a reliable guiding and supporting effect for the sliding seat 55, making the movement of the sliding seat 55 highly directional and repeatable, thereby ensuring that relevant cleaning or other operations relying on the movement of the sliding seat 55 can be carried out stably and precisely, improving the reliability and stability of the operation of the entire device, and avoiding problems such as equipment failures or performance degradation caused by abnormal movement of the sliding seat 55.

[0034] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
