Description

Technical Field

[0001] This utility model belongs to the field of FPC connector technology, and in particular relates to an FPC connector that is easy to assemble and disassemble. Background Technology

[0002] FFC / FPC flexible connectors are a new type of data cable made by pressing PET insulating material and extremely thin tin-plated flat copper wire together using high-tech automated equipment. They have advantages such as flexibility, easy bending and folding, thinness, small size, simple connection, convenient disassembly, and easy solution of electromagnetic shielding (EMI).

[0003] Existing FPC connectors typically use clips and slots to fix the base to the pressure plate, firmly pressing the circuit board. However, because the connection between the clips and slots is achieved through compression, when inserting or removing the clips, the operator must forcefully pry the pressure plate upwards to disengage the clips. This is laborious, and the clips are prone to wear or breakage due to repeated bending, thus failing to achieve the desired fixation effect and severely impacting the lifespan and connection reliability of the FPC connector. Furthermore, the unlocking mechanism of some connectors is exposed, making them susceptible to accidental disconnection during transportation or use, indicating room for improvement. To address these issues, an FPC connector that facilitates easy assembly and disassembly of FPCs is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an FPC connector that facilitates the assembly and disassembly of FPCs, thereby solving the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an FPC connector that facilitates the assembly and disassembly of FPCs, comprising a connector body and a cover plate. The cover plate is rotatably connected to the connector body, and the cover plate is provided with a locking mechanism and an unlocking mechanism. The locking mechanism includes at least one radially movable locking rod disposed on the cover plate and a slot disposed on the connector body for engaging with the locking rod. The unlocking mechanism includes a pressing rod slidably disposed on the cover plate, a transmission assembly linked to the pressing rod, and an elastic reset element acting between the transmission assembly and the cover plate. The transmission assembly converts the linear motion of the pressing rod into the radial motion of the locking rod, driving the locking rod to disengage from the slot, thereby unlocking the cover plate.

[0006] Preferably, the transmission assembly includes a pressing block fixed to the end of the pressing rod and a pushing block connected to the lever. The pushing block is a wedge-shaped block, and both ends of the pressing block are inclined surfaces. The inclined surfaces of the pushing block and the pressing block have the same inclination angle.

[0007] Preferably, the cover plate has an installation groove inside, and the inner wall of the installation groove has sliding grooves on both sides, and a slider that is fixedly connected to the push block is slidably arranged in the sliding groove.

[0008] Preferably, the inner wall of the slide groove is provided with limiting grooves on both sides, and the slider is provided with rolling balls partially accommodated in the limiting grooves on both sides.

[0009] Preferably, the bottom surface of the slide groove is provided with a strip groove, and a connecting rod is slidably disposed in the strip groove. One end of the connecting rod is fixedly connected to the slider, and the other end is fixedly connected to the locking rod. At least one locking block is fixedly provided on the upper surface of the connector body, and the locking groove is provided on one side of the locking block.

[0010] Preferably, the elastic reset element is a tension spring sleeved on the pressing rod, and the two ends of the tension spring are fixedly connected to the inner wall of the mounting groove and the pressing block, respectively.

[0011] Preferably, the cover plate is also provided with an anti-accidental activation mechanism for locking the pressing rod.

[0012] Preferably, the anti-accidental touch mechanism includes a rotating shaft rotatably mounted on the cover plate, a rotating rod fixedly connected to one end of the rotating shaft, and an elastic retaining ring fixedly mounted on the bottom surface of the rotating rod. The elastic retaining ring can selectively engage with the circumferential side of the pressing rod as the rotating rod rotates.

[0013] Preferably, the inner wall of the elastic retaining ring has multiple anti-slip grooves.

[0014] This utility model has the following beneficial effects: 1. This utility model achieves one-click unlocking, labor-saving operation, and non-destructive locking. Specifically, it uses a sloping transmission assembly consisting of a pressing rod, a squeezing block, and a pushing block to simultaneously convert the single axial pressing force acting on the pressing rod into the radial retraction movement of the two locking rods. This replaces the traditional method of forcibly prying the rotating plate to disengage the buckle. The process is smooth and labor-saving. Furthermore, the insertion and disengagement of the locking rods and the slots is a linear movement, avoiding the fatigue fracture and wear problems caused by repeated bending of traditional elastic buckles, and greatly improving the mechanical life of the connector. 2. This utility model effectively prevents accidental contact and improves safety. Specifically, it is achieved by setting an anti-accidental contact mechanism consisting of a rotating rod and an elastic retaining ring. During use or transportation, the rotating rod can be rotated to make the elastic retaining ring directly clamp onto the pressing rod from above, locking the pressing rod and preventing accidental unlocking of the connector due to accidental impact or contact, thus ensuring the reliability of the connection. The anti-slip texture on the inner wall of the elastic retaining ring further enhances the stability of the lock.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] Please see Figures 1-8 As shown, this utility model is an FPC connector that facilitates the assembly and disassembly of FPCs, including a connector body 1 and a cover plate 2. The cover plate 2 is rotatably connected to the connector body 1. The cover plate 2 is provided with a locking mechanism and an unlocking mechanism. The core function of the locking mechanism is to reliably lock the cover plate 2 onto the connector body 1. The mechanism includes at least one radially movable locking rod 15. Preferably, there are two locking rods 15, arranged symmetrically. On the connector body 1, a locking block 16 is fixedly provided at the position corresponding to the locking rod 15. The side of the locking block 16 is provided with a slot 20 for receiving the end of the locking rod 15. When the cover plate 2 is closed, the locking rod 15 extends radially under the driving action and inserts into the slot 20 to achieve locking.

[0022] The unlocking mechanism provides a labor-saving and quick unlocking method. The mechanism includes a pressing rod 3 that is slidably disposed on the front surface of the cover plate 2. A squeezing block 10 is fixedly connected to the end of the pressing rod 3. Inclined guide slopes are machined on both sides of the squeezing block 10. An installation groove 4 is opened inside the cover plate 2, and sliding grooves 5 are opened on both sides of its inner wall. Two sliders 6 are slidably disposed in the two sliding grooves 5 respectively. A pushing block 11 is fixedly connected to one end of each slider 6. The pushing block 11 is also a wedge-shaped block and has a slope that matches the slope of the squeezing block 10.

[0023] When the user presses the pressing rod 3, the squeezing block 10 moves accordingly, and its two inclined surfaces simultaneously squeeze the inclined surfaces of the two pushing blocks 11. Due to the action of the inclined surfaces, this axial pressing force is converted into a radial force that causes the two sliders 6 to move in opposite directions along the slide groove 5. The backward movement of the sliders 6 drives the locking rod 15 to retract radially in sync through the connecting block 14, so that it disengages from the locking groove 20 of the locking block 16, thereby releasing the lock on the cover plate 2. At this time, the user can easily flip the cover plate 2 upward.

[0024] To ensure smooth movement and reduce wear, the slider 6 is connected to the limiting groove 8 on the inner wall of the slide groove 5 by the ball bearings 17 on both sides, which converts sliding friction into rolling friction. A tension spring 9 is sleeved on the pressing rod 3. The two ends of the tension spring 9 are connected to the inner wall of the mounting groove 4 and the pressing block 10, respectively. When the user releases the pressing rod 3, the restoring force of the tension spring 9 will pull the pressing block 10 and the pressing rod 3 to automatically reset, preparing for the next operation.

[0025] To prevent the cover plate 2 from being accidentally opened due to accidental contact with the pressing rod 3 during transportation or use, this utility model adds an independent anti-accidental contact mechanism. The mechanism includes a rotating shaft 12 rotatably mounted on the cover plate 2. A rotating rod 13 is fixed to one end of the rotating shaft 12. An elastic retaining ring 18 made of elastic material (such as elastic plastic) is fixed to the bottom surface of the rotating rod 13. The elastic retaining ring 18 has an opening at the bottom so that it has a certain elastic clamping force.

[0026] When it is necessary to lock the pressing lever 3, simply rotate the lever 13 to allow the elastic retaining ring 18 to be fitted and locked onto the circumferential side of the pressing lever 3 from above. To enhance locking stability and prevent loosening under vibration, multiple anti-slip grooves 19 are machined on the inner wall of the elastic retaining ring 18 to increase the friction between it and the pressing lever 3. When normal operation is required, simply rotate the lever 13 in the opposite direction to disengage the elastic retaining ring 18 from the pressing lever 3.

[0027] Working principle: In the locked state, the cover plate 2 is closed, and under the action of the transmission component in the initial position, the end of the locking rod 15 is inserted into the slot 20 of the locking block 16 on the connector body 1, forming an interlock. At this time, the anti-accidental touch function is activated: by rotating the rotating rod 13, the elastic retaining ring 18 at its bottom is sleeved and locked onto the circumferential side of the pressing rod 3 from above. The elastic retaining ring 18 uses the elasticity of its own material and the anti-slip texture 19 on the inner wall to generate a strong static friction force, like a "mechanical lock", firmly locking the pressing rod 3 in the current position. In this state, even if an unexpected axial force is applied to the pressing rod 3, it cannot be moved, because the force is borne by the rigid structure and friction of the elastic retaining ring 18, thus effectively preventing accidental unlocking caused by accidental touch.

[0028] When normal disassembly is required, the anti-accidental contact lock must first be released: rotate the lever 13 in the opposite direction to disengage the elastic retaining ring 18 from the pressing rod 3, releasing its restraint. Then, the user can apply axial pressure to the pressing rod 3, which is transmitted through the pressing rod 3 to the pressing block 10 at its end. The inclined surfaces on both sides of the pressing block 10 then begin to press against the inclined surface of the cooperating push block 11. At this time, the elastic retaining ring 18 of the anti-accidental contact mechanism can rotate and lock onto the pressing rod 3. When disassembly is required, if the pressing rod 3 is locked, the lever 13 must first be rotated to disengage the elastic retaining ring 18 from the pressing rod 3. Subsequently, the user applies an axial pressing force to the pressing rod 3. This force is transmitted through the pressing rod 3 to the squeezing block 10 at its end. The inclined surfaces on both sides of the squeezing block 10 then begin to squeeze the inclined surfaces of the push block 11 that cooperate with it. Due to the inherent mechanical properties of the inclined surface structure, the linear motion of the squeezing block 10 is converted into the radial motion of the two push blocks 11 in opposite directions. The push blocks 11 drive the slider 6 to slide in opposite directions in the slide groove 5. This motion is then transmitted to the locking rod 15 through the connecting block 14, forcing the two locking rods 15 to retract radially towards the center in sync, so that their ends completely disengage from the slot 20, thereby releasing the lock on the cover plate 2. At the moment when the locking rod 15 disengages from the slot 20, the locking state of the cover plate 2 is released, and the user can easily flip the cover plate 2 upward to complete the disassembly of the FPC. Throughout the process, the balls 17 on both sides of the slider 6 roll within the limiting groove 8, ensuring smooth movement and reducing friction and wear. When the user releases the pressing rod 3, the tension spring 9 fitted on it releases the stored elastic potential energy, and its restoring force pulls the squeezing block 10 and the entire pressing rod 3 to automatically return to the initial position. At the same time, the internal transmission components also return to the initial state with the cooperation of various parts, preparing for the next locking operation.
