Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, specifically to a flip-type FPC connector. Background Technology
[0002] In existing flip-type FPC connectors, the positioning and limiting structure design of the terminals often has certain limitations. In actual use, the terminals are usually fixed only by a single limiting groove on the socket, and the part extending into the insertion groove lacks effective lateral restraint. When the FPC is inserted or removed, slight lateral collisions or friction may occur between the FPC and the terminal, at which point the terminal is prone to lateral displacement due to force. At the same time, during the flip-top closing process, the pressure applied to the terminal by the cam block may generate a lateral component force. If there is a gap between the clearance groove on the flip-top and the terminal or the fitting precision is insufficient, it is difficult to form a stable constraint on the terminal, which may also lead to lateral displacement of the terminal. This displacement may cause the terminal and the conductive part on the FPC to be misaligned, resulting in contact misalignment, affecting the accuracy of the electrical connection. In scenarios with high requirements for connection accuracy, such problems may adversely affect the normal operation of the equipment. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flip-type FPC connector.
[0004] The objective of this utility model can be achieved through the following technical solution: A flip-type FPC connector includes a base, on which a plurality of first limiting grooves are spaced apart, and a terminal is fixedly disposed in the first limiting groove. An insertion groove adapted to the FPC is provided at the front end of the first limiting groove on the base, and the insertion groove is connected to the first limiting groove. A flip cover is rotatably connected to the position of the insertion groove on the base. The flip cover is provided with clearance grooves spaced apart, each corresponding to one of the first limiting grooves, and a cam block is disposed in the clearance groove. A locking mechanism is provided on the base and the flip cover respectively, for locking the flip cover to the base. One end of the terminal is fixed in the first limiting groove, and the other end extends into the insertion groove and is engaged in the corresponding clearance groove.
[0005] Preferably, the locking mechanism includes waist holes on the rubber base located on both sides of the insertion groove, rotating shafts on both sides of the flip cover that cooperate with the waist holes, a first slot on the rotating shaft, and a first locking block on one side of the waist hole that cooperates with the first slot.
[0006] Preferably, a second locking block is provided at the end of the flip cover away from the pivot, and a second locking groove corresponding to the second locking block is provided on the rubber base.
[0007] Preferably, the terminal includes a fixed arm and an elastic arm, one end of the fixed arm and the elastic arm are connected as one unit by a connecting arm, the bottom of the connecting arm is provided with a welding foot, and the free end of the elastic arm is provided with a contact point.

[0009] Preferably, a second limiting groove is provided between the first limiting groove and the insertion groove, and the second limiting groove corresponds to the first limiting groove and the clearance groove respectively.
[0010] The beneficial effects of this utility model are as follows: by initially fixing the terminal through the first limiting groove, combined with the lateral constraint formed by the clearance groove on the flip cover on the extension section of the terminal, the left and right offset of the terminal during the insertion and removal of the FPC and the pressure of the flip cover can be effectively limited, ensuring that the terminal and the conductive part on the FPC always maintain precise alignment; at the same time, the downward pressure applied to the terminal by the cam block as the flip cover rotates can stably act on the preset contact position, improving the accuracy and reliability of the electrical connection.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] See Figures 1 to 7As shown, the structure of this utility model is as follows: a flip-type FPC connector, including a base 1, with a plurality of first limiting grooves 2 spaced apart on the base 1, a terminal 3 fixedly disposed in the first limiting groove 2, and an insertion groove 4 adapted to the FPC located at the front end of the first limiting groove 2 on the base 1, the insertion groove 4 being connected to the first limiting groove 2; a flip cover 5, the flip cover 5 being rotatably connected to the position of the insertion groove 4 on the base 1, the flip cover 5 having clearance grooves 6 spaced apart corresponding to the first limiting grooves 2, and a cam block 7 disposed in the clearance groove 6; a locking mechanism 8, the locking mechanism 8 being disposed on the base 1 and the flip cover 5 respectively, for locking the flip cover 5 to the base 1; wherein, one end of the terminal 3 is fixed in the first limiting groove 2, and the other end extends into the insertion groove 4 and is engaged in the corresponding clearance groove 6. Specifically, the base 1 serves as a bearing base, and the spaced first limiting grooves 2 are used to fix the terminal 3, ensuring the initial position of the terminal 3 is accurate; the insertion groove 4 is the FPC An insertion channel is provided and communicates with the first limiting groove 2 to ensure that the FPC corresponds to the terminal 3 after insertion. The flip cover 5 is opened and closed by rotation. The clearance groove 6 on it is adapted to the terminal 3, accommodating the extension of the terminal 3 and restricting the left and right movement of the terminal 3 through the cooperation of the inner wall with the terminal 3. The cam block 7 is located in the clearance groove 6 and converts the rotational motion into downward pressure on the terminal 3 when the flip cover 5 rotates. The locking mechanism 8 locks its position after the flip cover 5 is closed. During operation, after the FPC is inserted into the insertion groove 4, the flip cover 5 is flipped so that the cam block 7 presses down on the terminal 3. The clearance groove 6 restricts the lateral displacement of the terminal 3, ensuring that the terminal 3 accurately presses against the conductive part of the FPC. The locking mechanism 8 locks the flip cover 5 to maintain contact and achieve a reliable connection. When the cover is opened, the lock is unlocked, the flip cover 5 is flipped, the cam block 7 releases the terminal 3, and the FPC can be easily removed.
[0024] like Figure 6 , Figure 7 As shown, the locking mechanism 8 includes waist holes 9 on both sides of the insertion slot 4 on the rubber base 1. The flip cover 5 has rotating shafts 10 on both sides that mate with the waist holes 9. Each rotating shaft 10 has a first slot 11, and one side of each waist hole 9 has a first locking block 12 that mates with the first slot 11. Specifically, the waist holes 9 on both sides of the rubber base 1 mate with the rotating shafts 10 of the flip cover 5, serving both as the fulcrum for the flip cover 5's rotation and providing space for the rotating shafts 10 to move back and forth. The first slot 11 on the rotating shaft 10 and the first locking block 12 on the side of the waist hole 9 form a locking engagement. During operation, when the flip cover 5 is closed and pushed forward, the rotating shaft 10 moves forward along the waist holes 9, causing the first locking block 12 to engage with the first slot 11. Mechanical engagement restricts the rotation of the rotating shaft 10, thus locking the flip cover 5. When opening the cover, pulling the flip cover 5 backward causes the rotating shaft 10 to move backward, disengaging the first locking block 12 from the first slot 11, releasing the lock. The rotating shaft 10 can then rotate freely, allowing the flip cover 5 to open smoothly.
[0025] like Figure 6 , Figure 7As shown, a second locking block 13 is provided at the end of the flip cover 5 away from the pivot 10, and a second locking groove 14 corresponding to the second locking block 13 is provided on the rubber base 1. Specifically, the second locking block 13 on the flip cover 5 and the second locking groove 14 on the rubber base 1 form a secondary locking engagement. During operation, as the flip cover 5 closes and is pushed forward, the second locking block 13 moves with the flip cover 5 and engages in the second locking groove 14, forming a double fixation with the locking of the first locking block 12 and the first locking groove 11, ensuring that the flip cover 5 closes stably. When opening the cover, the flip cover 5 is pulled backward to make the second locking block 13 disengage from the second locking groove 14, which cooperates with the first locking block 12 to unlock, ensuring that the flip cover 5 opens smoothly.
[0026] like Figure 5 As shown, terminal 3 includes a fixed arm 15 and an elastic arm 16. One end of the fixed arm 15 and the elastic arm 16 are connected as one unit by a connecting arm 17. The bottom of the connecting arm 17 is provided with a welding foot 18, and the free end of the elastic arm 16 is provided with a contact point 19. Specifically, the fixed arm 15 of terminal 3 is used to stably install terminal 3 in the first limiting groove 2 to ensure that the overall position is fixed; the elastic arm 16 has elastic deformation capability, and the contact point 19 at its free end is the core part that contacts the conductive part of the FPC. The elastic arm 16 is also inserted into the clearance groove 6 of the flip cover 5. The clearance groove 6 restricts the left and right movement of the elastic arm 16 through its inner wall; the connecting arm 17 connects the fixed arm 15 and the elastic arm 16 as one unit, and the welding foot 18 at the bottom is used to weld and conduct to the external circuit. When the flip cover 5 is closed, the cam block 7 presses down on the elastic arm 16, causing it to deform towards the FPC. The clearance groove 6 restricts the lateral displacement of the elastic arm 16, ensuring that the contact 19 is accurately pressed on the conductive part of the FPC to achieve electrical connection. When the flip cover 5 is opened, the elastic arm 16 returns to its original position due to its own elasticity, and the contact 19 separates from the FPC.
[0027] like Figure 4 , Figure 7 As shown, a protrusion 20 is provided at the bottom of the flip cover 5 corresponding to the position of the insertion slot 4. Specifically, the protrusion 20 at the bottom of the flip cover 5 corresponds to the position of the insertion slot 4, and its height is adapted to the thickness of the FPC. During operation, after the flip cover 5 is closed, the protrusion 20 moves down with the flip cover 5 and presses against the surface of the FPC in the insertion slot 4, pressing the FPC firmly against the inner wall of the insertion slot 4 to prevent the FPC from moving. At the same time, the clearance groove 6 on the flip cover 5 restricts the left and right movement of the terminal 3. The two work together to ensure that the terminal 3 contact 19 and the FPC conductive part are always accurately aligned from both the aspects of FPC fixation and terminal 3 positioning, avoiding poor contact caused by misalignment of either side.
[0028] like Figure 1 , Figure 2 , Figure 3As shown, a second limiting groove 21 is provided between the first limiting groove 2 and the insertion groove 4. The second limiting groove 21 corresponds to the first limiting groove 2 and the clearance groove 6 respectively. Specifically, the second limiting groove 21 is located between the first limiting groove 2 and the insertion groove 4. Its position corresponds precisely to the first limiting groove 2 and the clearance groove 6, and its width is adapted to the elastic arm 16 of the terminal 3. Its function is not only to limit the elastic arm 16 in the left and right directions, restricting its left and right movement when the flip cover 5 is closed and the cam block 7 presses down on the elastic arm 16; but also, when the flip cover 5 is open, it ensures that the elastic arm 16 always remains in the position corresponding to the relief groove 6 by continuously constraining the elastic arm 16. During operation, regardless of whether the flip cover 5 is open or closed, the middle section of the elastic arm 16 is always located in the second limiting groove 21. The second limiting groove 21 restricts the lateral displacement of the elastic arm 16 through its two side walls: when the flip cover 5 is open, the elastic arm 16 resets under its own elasticity, and the second limiting groove 21 ensures that it will not be laterally displaced due to external force or vibration, and always maintains its position corresponding to the relief groove 6 on the flip cover 5; when the flip cover 5 is closed, the elastic arm 16 can accurately engage with the relief groove 6, and the relief groove 6 further restricts its lateral movement, ultimately providing double protection for the precise contact between the terminal 3 contact 19 and the FPC conductive part.
[0029] In practical use, when connecting the FPC, the locking mechanism 8 is in the unlocked state, and the flip cover 5 is in the open state at the rotational connection position around the base 1. The first limiting groove 2 on the base 1 fixes the terminal 3 to ensure its initial position is stable. One end of the terminal 3 is fixed to the first limiting groove 2, and the other end extends to the insertion groove 4 and is engaged with the clearance groove 6 on the flip cover 5. The clearance groove 6 restricts the left and right displacement of the terminal 3 by fitting against the inner wall, so that the terminal 3 is aligned with the preset path of the FPC in the insertion groove 4. The FPC is pushed in along the insertion groove 4 of the base 1. The insertion groove 4 guides the FPC to move along the preset trajectory. Because the insertion groove 4 is connected to the first limiting groove 2 and the terminal 3 is maintained in a lateral position by the clearance groove 6, the FPC... The conductive area on the cover is precisely aligned with the portion of terminal 3 extending into the insertion slot 4; then the flip cover 5 is flipped to rotate towards the base 1. The cam block 7 on the flip cover 5 gradually contacts and applies pressure to terminal 3 as the flip cover 5 moves. As the flip cover 5 rotates, the pressure of the cam block 7 on terminal 3 increases, forcing terminal 3 to deform towards the inside of the insertion slot 4. The inner wall of the clearance slot 6 always adheres to both sides of terminal 3, strictly limiting its lateral displacement, ensuring that terminal 3 and the conductive area of the FPC are precisely aligned. When the flip cover 5 is fully closed, the base 1 and the locking mechanism 8 on the flip cover 5 interact to lock the flip cover 5 in the closed position. At this time, the pressure of the cam block 7 on terminal 3 is stable, and terminal 3 presses against the FPC to achieve electrical connection. The clearance slot 6 and the first limiting slot 2 cooperate to limit the lateral movement of terminal 3. The locking mechanism 8 maintains the position of the flip cover 5, together ensuring stable connection and completing the FPC connection.

However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
