Description

Technical Field

[0001] This utility model relates to the field of FFC flexible flat cable technology, and in particular to a quick-release structure for FFC flexible flat cables. Background Technology

[0002] FFC (Flexible Flat Cable) is a high-performance cable widely used for internal connections in electronic devices. It uses multi-layer polyester film as insulation material and contains multiple parallel flat conductors. Through a special manufacturing process, it has high flexibility and good electrical performance. FFC cables are characterized by small size, light weight, and flexible wiring, which can easily adapt to the internal space of various compact electronic devices, realize high-speed signal transmission between different components, have high transmission rate, low signal loss, effectively reduce electromagnetic interference, and ensure stable signal transmission.

[0003] In the existing technology, most FFC flexible flat cables lack quick-release structures, which brings many inconveniences to the assembly, maintenance and upgrade of electronic devices. Since FFC cables are usually fixed to the circuit board by soldering or clips, once replacement or repair is needed, it is often necessary to use professional tools for disassembly, which is complicated and time-consuming. In addition, the cable or circuit board is easily damaged during disassembly, increasing maintenance costs. FFC cables without quick-release structures are also difficult to replace quickly when upgrading equipment, which limits the flexibility and maintainability of the equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-release structure for FFC flexible flat cables.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a quick-release structure for an FFC flexible flat cable, comprising an FFC flexible cable, an FFC end, and a connector slot. One end of the FFC flexible cable is electrically connected to the FFC end. The FFC end is located on the inner wall of the connector slot. A component slot is formed inside the FFC end. Two push rods are slidably connected to the inner wall of the component slot. A driven inclined block is fixed to one end of each push rod, and a clamping arm is fixed to the other end of each push rod. A clamping claw is fixed to the bottom end of the clamping arm. Clamping hook slots are formed on both sides of the connector slot. The clamping claw is located on the inner wall of the clamping hook slot. A second spring is provided on the surface of the push rod. One end of the second spring is fixed to one side of the driven inclined block, and the other end of the second spring is fixed to the inner wall of the component slot. A driving inclined block is provided on the surface of the driven inclined block. A limit bracket is fixed to the inner wall of the component slot. A button is fixed to one side of the driving inclined block. A first spring is provided on the surface of the button. One end of the first spring is fixed to one side of the driving inclined block, and the other end of the first spring is fixed to the inner wall of the component slot.

[0006] Preferably, a slide block one is fixed to one side of the FFC end, and a slide block two is fixed to the other side of the FFC end. A slide groove one is formed on the inner wall of the connector slot, and slide block one slides on the inner wall of slide groove one. A slide groove two is formed on the inner wall of the connector slot, and slide block two slides on the inner wall of slide groove two. In the prior art, FFC flexible flat cables mostly lack guiding devices during installation, which brings many inconveniences to the installation work. Because FFC cables are relatively soft and flat, inaccurate alignment, cable bending, or misalignment are prone to occur when inserting them into the connector slot. This not only increases the difficulty and time cost of installation but may also lead to poor contact between the cable and the slot, affecting the stability and reliability of signal transmission. In addition, repeated adjustments and corrections may cause physical damage to the cable, reducing its service life. To address these problems, this utility model adopts a guiding device. In the guiding device of the FFC flexible flat cable, a slide block one is fixed to one side of the FFC end, and a slide block two is fixed to the other side. Corresponding slide grooves one and two are formed on the inner wall of the connector slot. When… When the FFC terminal is inserted into the connector slot, slide block one and slide block two slide along slide groove one and slide groove two respectively. This design allows the FFC terminal to move smoothly and accurately along the predetermined track during insertion, effectively avoiding problems such as bending, offset, or inaccurate alignment of the cable during insertion. This significantly improves installation efficiency and quality. By introducing guiding devices, such as the design of slide blocks and slide grooves, it is possible to ensure precise alignment of the FFC terminal when inserted into the connector slot, avoiding cable bending or offset, thereby reducing installation difficulty and time costs. At the same time, this guiding device can effectively prevent poor contact between the cable and the slot, ensuring the stability and reliability of signal transmission, avoiding physical damage to the cable caused by repeated adjustments and corrections, and extending the cable's service life.

[0007] Preferably, the connector slot has a foolproof slot on its inner wall, and a foolproof block is fixed to one side of the FFC end, the foolproof block being disposed on the inner wall of the foolproof slot. In the prior art, FFC flexible flat cables typically lack a foolproof insertion device, which brings many problems to the installation process. Because FFC cables are relatively flexible and flat, without a foolproof design, it is easy to insert them into the connector slot in the wrong direction or with inaccurate alignment. This not only increases the difficulty and time cost of installation but may also lead to poor contact between the cable and the slot, affecting the stability and reliability of signal transmission. To address these problems, this invention employs a foolproof insertion device. In the foolproof insertion device for FFC flexible flat cables, the connector slot has a foolproof slot on its inner wall, and a matching foolproof block is fixed to one side of the FFC end. When the FFC end is inserted into the connector slot, the foolproof block must be accurately aligned and inserted into the foolproof slot. This design ensures that the FFC end can only be inserted into the connector slot in the correct manner, thereby preventing problems such as poor contact and unstable signal transmission caused by incorrect insertion direction or inaccurate alignment. This significantly improves installation accuracy and efficiency. By introducing foolproof designs, such as a matching structure between foolproof blocks and foolproof slots, it ensures that the FFC end is inserted into the connector slot only in the correct manner, thus avoiding problems such as incorrect insertion direction or inaccurate alignment. This not only reduces installation difficulty and time costs but also effectively prevents signal transmission instability caused by poor contact, improving the reliability and stability of the equipment.

[0008] Preferably, both the FFC terminal and the connector slot surface are coated with an anti-static coating. Applying an anti-static coating to the FFC terminal and connector slot surface can effectively reduce the accumulation and release of static electricity. Static electricity may damage sensitive electronic components during installation or use, leading to signal transmission interruption or equipment failure. The anti-static coating can reduce the impact of static electricity on cables and slots, improve the reliability and stability of the equipment, and reduce maintenance costs and equipment downtime caused by electrostatic discharge.

[0009] Preferably, both the FFC terminal and the connector slot are made of transparent material. Using transparent material for the FFC terminal and connector slot significantly improves visibility and convenience during installation and maintenance. The transparent material allows installers to directly observe the connection between the cable and the slot, ensuring correct insertion direction and precise alignment, thereby reducing poor contact or damage caused by misoperation.

[0010] Preferably, the driven wedge surface is smooth, and the driving wedge near the driven wedge is also smooth. Designing the driven wedge surface and the driving wedge near the driven wedge as smooth significantly reduces friction between them. This design makes the movement smoother when the driving wedge pushes the driven wedge, reducing jamming or wear caused by friction.

[0011] Preferably, the button has anti-slip textured lines on the side away from the drive ramp, and these anti-slip textures are arranged in an array. Having an array of anti-slip textured lines on the side of the button away from the drive ramp significantly increases friction during operation, thereby enhancing operational stability and reliability. This design allows users to firmly grip the button and operate accurately even with sweaty hands or in a humid environment, avoiding operational errors caused by slipping.

[0012] Beneficial effects:

[0013] 1. In existing technologies, most FFC (Flexible Flat Cable) cables lack quick-release structures, which brings many inconveniences to the assembly, repair, and upgrade of electronic equipment. Since FFC cables are usually fixed to the circuit board by welding or clips, once replacement or repair is needed, special tools are often required for disassembly, which is complex and time-consuming. In addition, the cables or circuit boards are easily damaged during disassembly, increasing repair costs. FFC cables without quick-release structures are also difficult to replace quickly when upgrading equipment, limiting the flexibility and maintainability of the equipment. To address these issues, this utility model adopts a quick-release structure, which can significantly improve the efficiency of assembly, repair, and upgrade of electronic equipment. By introducing a quick-release structure and the design of clamping claws and clamping slots, FFC cables can be quickly installed and removed without the need for special tools, greatly simplifying the operation process and shortening the time. This not only reduces the risk of cable or circuit board damage due to improper disassembly and lowers repair costs, but also enhances the flexibility and maintainability of the equipment during upgrades. In the scenario of rapid replacement of electronic equipment on the production line or in laboratory equipment, the quick-release structure can quickly replace cables, improve work efficiency, and ensure the efficient operation and rapid updates of equipment.

[0014] 2. In existing technologies, FFC flexible flat cables mostly lack guiding devices during installation, which brings many inconveniences to the installation work. Because FFC cables are relatively soft and flat, inaccurate alignment, cable bending, or misalignment are prone to occur when inserting them into connector slots. This not only increases the difficulty and time cost of installation, but may also lead to poor contact between the cable and the slot, affecting the stability and reliability of signal transmission. In addition, repeated adjustments and corrections may cause physical damage to the cable and reduce its service life. To address these issues, this utility model adopts a guiding device, which can significantly improve installation efficiency and quality. By introducing a guiding device, such as the design of a slide block and slide groove, it can ensure that the FFC end is accurately aligned when inserted into the connector slot, avoiding cable bending or misalignment, thereby reducing installation difficulty and time cost. At the same time, this guiding device can effectively prevent poor contact between the cable and the slot, ensuring the stability and reliability of signal transmission, avoiding physical damage to the cable caused by repeated adjustments and corrections, and extending the service life of the cable.

[0015] 3. In existing technologies, FFC flexible flat cables typically lack a foolproof insertion device, which brings many problems to the installation process. Because FFC cables are inherently flexible and flat, without a foolproof design, incorrect insertion direction or inaccurate alignment is easily encountered when inserting them into the connector slot. This not only increases the difficulty and time cost of installation but may also lead to poor contact between the cable and the slot, affecting the stability and reliability of signal transmission. To address these issues, this invention employs a foolproof insertion device, significantly improving the accuracy and efficiency of installation. By introducing a foolproof design, such as a matching structure between a foolproof block and a foolproof slot, it ensures that the FFC end can only be inserted into the connector slot in the correct manner, thereby avoiding incorrect insertion direction or inaccurate alignment. This not only reduces the difficulty and time cost of installation but also effectively prevents signal transmission instability caused by poor contact, improving the reliability and stability of the equipment.

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0025] Reference Figure 1-4The quick-release structure for FFC flexible flat cable includes an FFC flexible cable 1, an FFC end 101, and a connector slot 102. One end of the FFC flexible cable 1 is electrically connected to the FFC end 101, which is located on the inner wall of the connector slot 102. An assembly slot 103 is provided inside the FFC end 101, and two push rods 104 are slidably connected to the inner wall of the assembly slot 103. One end of each push rod 104 is fixed with a driven inclined block 105, and the other end is fixed with a clamping arm 106. A clamping claw 107 is fixed to the bottom end of the clamping arm 106. The connector slot 102 has openings on both sides. A clamping hook groove 108 is provided, and a clamping claw 107 is provided on the inner wall of the clamping hook groove 108. A second spring 113 is provided on the surface of the push rod 104. One end of the second spring 113 is fixed to one side of the driven inclined block 105, and the other end of the second spring 113 is fixed to the inner wall of the component groove 103. A driving inclined block 109 is provided on the surface of the driven inclined block 105. A limit frame 110 is fixed on the inner wall of the component groove 103. A button 111 is fixed on one side of the driving inclined block 109. A first spring 112 is provided on the surface of the button 111. One end of the first spring 112 is fixed to one side of the driving inclined block 109, and the other end of the first spring 112 is fixed to the inner wall of the component groove 103. In existing technologies, most FFC (Flexible Flat Cable) cables lack quick-release structures, which brings many inconveniences to the assembly, repair, and upgrade of electronic devices. Since FFC cables are typically fixed to circuit boards by soldering or clips, replacement or repair often requires disassembly using specialized tools, which is complex and time-consuming. Furthermore, the disassembly process can easily damage the cable or circuit board, increasing repair costs. FFC cables without quick-release structures are also difficult to replace quickly during equipment upgrades, limiting the flexibility and maintainability of the equipment. To address these issues, this invention adopts a quick-release structure. In the quick-release structure of the FFC flexible flat cable, when installation is required... When using an FFC cable, insert the FFC end 101 into the connector slot 102. At this time, the clamping claw 107 automatically engages with the clamping groove 108 under the action of the second spring 113, achieving a stable connection between the FFC end 101 and the connector slot 102. When disassembly is required, press the button 111. The button 111 pushes the driven inclined block 105 through the drive inclined block 109, causing the push rod 104 to move inward. The clamping claw 107 disengages from the clamping groove 108, allowing the FFC end 101 to be easily pulled out. The first spring 112 and the second spring 113 provide the reset force for the button and the push rod, respectively, ensuring the reliability and reusability of the structure.

[0026] A slide rail block 101 is fixed to one side of the FFC end 101, and a slide rail block 201 is fixed to the other side of the FFC end 101. A slide rail groove 202 is formed on the inner wall of the connector slot 102, and the slide rail block 102 slides on the inner wall of the slide rail groove 202. A slide rail groove 203 is formed on the inner wall of the connector slot 102, and the slide rail block 201 slides on the inner wall of the slide rail groove 203. In the prior art, FFC flexible flat cables mostly lack guiding devices during installation, which brings many inconveniences to the installation work. Because FFC cables are relatively soft and flat, inaccurate alignment, cable bending, or misalignment are prone to occur when inserting them into the connector slot. This not only increases the difficulty and time cost of installation but may also lead to poor contact between the cable and the slot, affecting the stability and reliability of signal transmission. In addition, repeated adjustments and corrections may cause physical damage to the cable, reducing its service life. To address these problems, this utility model adopts a guiding device for the FFC flexible flat cable... In the guiding device, a slide block 2 is fixed on one side of the FFC terminal 101 and a slide block 201 is fixed on the other side. The inner wall of the connector slot 102 is provided with corresponding slide grooves 202 and 203. When the FFC terminal 101 is inserted into the connector slot 102, the slide block 2 and the slide block 201 slide along the slide grooves 202 and 203 respectively. This design allows the FFC terminal 101 to move smoothly and accurately along the predetermined track during the insertion process, effectively avoiding problems such as bending, offset or inaccurate alignment that may occur when the cable is inserted.

[0027] A foolproof slot 3 is provided on the inner wall of the connector slot 102, and a foolproof block 301 is fixed on one side of the FFC end 101. The foolproof block 301 is located on the inner wall of the foolproof slot 3. In the prior art, FFC flexible flat cables usually lack a foolproof insertion device, which brings many problems to the installation process. Because FFC cables are relatively soft and flat, without a foolproof design, it is easy to have incorrect insertion direction or inaccurate alignment when inserting them into the connector slot. This not only increases the difficulty and time cost of installation, but may also lead to poor contact between the cable and the slot, affecting the stability and reliability of signal transmission. To address this problem, this utility model adopts a foolproof insertion device. In the foolproof insertion device of the FFC flexible flat cable, a foolproof slot 3 is provided on the inner wall of the connector slot 102, and a matching foolproof block 301 is fixed on one side of the FFC end 101. When the FFC end 101 is inserted into the connector slot 102, the foolproof block 301 must be accurately aligned and inserted into the foolproof slot 3. This design ensures that the FFC end 101 can only be inserted into the connector slot 102 in the correct manner, thereby preventing problems such as poor contact and unstable signal transmission caused by incorrect insertion direction or inaccurate alignment.

[0028] Both the FFC terminal 101 and the connector slot 102 are coated with an anti-static coating. This coating effectively reduces the accumulation and release of static electricity, which can damage sensitive electronic components during installation or use, leading to signal transmission interruptions or equipment malfunctions. The anti-static coating reduces the impact of static electricity on cables and slots, improving equipment reliability and stability, and reducing maintenance costs and downtime caused by electrostatic discharge. Both the FFC terminal 101 and the connector slot 102 are made of transparent material. This significantly improves visibility and convenience during installation and maintenance. The transparency allows installers to directly observe the cable and slot connection, ensuring correct insertion and precise alignment, thereby reducing connection problems caused by misoperation. In case of poor contact or damage, the surface of the driven inclined block 105 is smooth, and the side of the driving inclined block 109 near the driven inclined block 105 is also smooth. Designing the surfaces of the driven inclined block 105 and the side of the driving inclined block 109 near the driven inclined block 105 to be smooth can significantly reduce the friction between them. This design makes the movement smoother when the driving inclined block 109 pushes the driven inclined block 105, reducing the jamming or wear caused by friction. The button 111 has anti-slip textures on the side away from the driving inclined block 109. The anti-slip textures are arranged in an array. The array of anti-slip textures on the side of the button 111 away from the driving inclined block 109 can significantly improve the friction during operation, thereby enhancing the stability and reliability of operation. This design allows the user to firmly hold the button and operate accurately even when their hands are sweaty or the environment is humid, avoiding operational errors caused by slipping.

[0029] The working principle of this utility model is as follows: In the quick-release structure of the FFC flexible flat cable, when the FFC cable needs to be installed, the FFC end 101 is inserted into the connector slot 102. At this time, the clamping claw 107 automatically engages with the clamping hook groove 108 under the action of the second spring 113, achieving a stable connection between the FFC end 101 and the connector slot 102. When disassembly is required, the button 111 is pressed. The button 111 pushes the driven inclined block 105 through the driving inclined block 109, causing the push rod 104 to move inward, and the clamping claw 107 disengages from the clamping hook groove 108, thus allowing the FFC end 101 to be easily pulled out. The first spring 112 and the second spring 113 respectively provide the restoring force for the button and the push rod, ensuring the reliability and reusability of the structure. The guide device for the FFC flexible flat cable... In the center, a slide block 2 is fixed on one side of the FFC terminal 101, and a slide block 201 is fixed on the other side. Corresponding slide grooves 202 and 203 are respectively formed on the inner wall of the connector slot 102. When the FFC terminal 101 is inserted into the connector slot 102, slide blocks 2 and 201 slide along slide grooves 202 and 203 respectively. This design allows the FFC terminal 101 to move smoothly and accurately along a predetermined track during insertion, effectively avoiding problems such as bending, offset, or inaccurate alignment that may occur during cable insertion. In the foolproof insertion device for the FFC flexible flat cable, a foolproof slot 3 is formed on the inner wall of the connector slot 102, and a matching foolproof block 301 is fixed on one side of the FFC terminal 101. When the FFC terminal 101 is inserted into the connector slot 102, the foolproof block 301 must be accurately aligned and inserted into the foolproof slot 3. This design ensures that the FFC end 101 can only be inserted into the connector slot 102 in the correct manner, thereby preventing problems such as poor contact and unstable signal transmission caused by incorrect insertion direction or inaccurate alignment.
