Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of FPC connectors, in particular to an FPC connector with a pop-up structure. Background Art
[0002] An FPC connector is an electronic component used to connect flexible printed circuits to electronic devices. FPC connectors are usually small, flexible, and can achieve complex circuit connections in a limited space. This connector is composed of conductive metal foil, insulating substrate, and connectors, and has extremely high flexibility to adapt to the shape of printed circuit boards. FPC connectors are mainly based on the connection between their metal terminals and the metal points at the bottom of the circuit board. When the FPC connector is inserted into the corresponding slot, its metal resistors will be in close contact with the metal contacts at the bottom of the circuit board, thereby establishing an electrical connection.
[0003] When the existing FPC connectors are in use, in order to facilitate the connection between the two connectors, an FPC cable row is usually installed and fixed between the two connectors. Currently, the FPC cable row is usually directly inserted into the FPC connector, and then the FPC cable row is fixed by pressing the cover. Although this fixation is convenient, the connector is usually used in a limited space, which makes it more troublesome to replace the cable row later. Moreover, when manually pulling out the cable row, it is difficult to pull the cable row out horizontally from the connector, which will cause the cable row to bend. Since the cable row is relatively fragile, it is easy to be scratched and cause functional failure. Utility Model Content
[0004] The purpose of the utility model is to provide an FPC connector with a pop-up structure to solve the problems raised in the above background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] An FPC connector with a pop-up structure comprises a connector body with an L-shaped cross section, a pressure plate is slidably connected between two opposite side surfaces inside the connector body, a cover plate is rotatably connected between the top ends of the two opposite side surfaces inside the connector body, L-shaped blocks for locking the cover plate are arranged at both ends of the top surface of the connector body, a movable plate is arranged inside the connector body along its length direction, and a plurality of support springs are fixed at equal intervals between the movable plate and the connector body.
[0007] Furthermore, a rectangular groove is formed at both ends of the inner bottom surface of the connector body, and plug-in blocks plugged into the rectangular groove at corresponding positions are fixedly connected to the rectangular grooves at both ends of the bottom surface of the pressure plate.

[0009] Furthermore, both ends of the bottom surface of the cover plate are fixedly connected with a stop block, a reel is rotatably connected between the two stop blocks, a pull rope fixed to the pressure plate is wound around the outer wall of the reel, and torsion springs are respectively arranged between the two ends of the reel and the stop blocks at corresponding positions.
[0010] Furthermore, both ends of the top surface of the movable plate are fixedly connected with connecting blocks, one side surface of the connecting block is fixedly connected with an arc block 2, and both ends of the bottom surface of the cover plate are fixedly connected with L-shaped contact blocks.
[0011] Furthermore, two rectangular grooves for sliding L-shaped blocks are provided at both ends of the top surface of the connector body, a supporting spring is fixedly connected between the L-shaped block and the rectangular groove at the corresponding position, and an arc-shaped block is fixedly connected to the top surface of the L-shaped block.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figures 1 to 6 In an embodiment of the utility model, an FPC connector with a pop-up structure includes a connector body 1 with an L-shaped cross-section, a pressure plate 2 is slidably connected between two opposite side surfaces inside the connector body 1, a cover plate 3 is rotatably connected between the tops of two opposite side surfaces inside the connector body 1, L-shaped blocks 4 for locking the cover plate 3 are provided at both ends of the top surface of the connector body 1, a movable plate 5 is provided inside the connector body 1 along its length direction, and a plurality of support springs 51 are fixed at equal intervals between the movable plate 5 and the connector body 1.
[0024] Specifically, first insert one end of the wire row between the pressure plate 2 and the connector body 1, and the end of the wire row is against the movable plate 5 and pushed backward until the wire row can no longer be pushed. At this time, the metal guide block at the end of the wire row contacts the metal guide block on the inner bottom surface of the connector body 1, and then the pressure plate 2 is pressed down and covers the cover plate 3, so that the end of the wire row is fixed inside the connector body 1, and then the cover plate 3 is limited by two L-shaped blocks 4 to prevent the cover plate 3 from being opened, and then the connector body 1 with the fixed wire row is welded to the circuit board. When the wire row needs to be replaced, first move the two L-shaped blocks 4, then flip the cover plate 3 and move the pressure plate 2 up. At this time, the compressed multiple support springs three 51 push the movable plate 5 to move, and the movable plate 5 can pop out the wire row from the inside of the connector body 1. Because the multiple support springs three 51 are restored to their original state, the released force is parallel to the connector body 1, so that the end of the wire row can be popped out horizontally, thereby avoiding the wire row being manually pulled out, which causes The bending of the wire row causes the function of the wire row to fail, and then the connector body 1 is removed from the circuit board, and the new wire row is fixed in the connector body 1, and then the connector body 1 is soldered to the circuit board (as for why the wire row should be taken out of the connector body 1 first, and then the connector body 1 is removed from the circuit board, if it is forcibly pulled out, there may be more wire rows on the circuit board. When manually pulling it out, due to the obstruction of other wire rows and connectors, the staff may instinctively pull the wire row out of the connector body 1 at an angle, and the wire row is usually small, so the wire row can be pulled out horizontally from the inside of the connector body 1 through automatic pop-up. If the connector body 1 is removed from the circuit board first and then the wire row is pulled out, because the wire rows on the circuit board may be staggered with each other, if the connector body 1 is removed first, when the connector body 1 is taken down from the circuit board, the wire row is still fixed inside the connector body 1, so the wire row will still be bent).
[0025] Embodiment 1
[0026] like Figure 2 and Figure 3 As shown, in this embodiment, rectangular grooves 11 are provided at both ends of the inner bottom surface of the connector body 1, and plug-in blocks 21 that are plugged into the rectangular grooves 11 at the corresponding positions are fixedly connected at the two ends of the bottom surface of the pressure plate 2, and limiting grooves 12 are provided on the two opposite side surfaces inside the connector body 1, and sliders 22 that slide with the limiting grooves 12 at the corresponding positions are fixedly connected at both ends of the pressure plate 2, and a support spring 23 is fixedly connected between the slider 22 and the limiting grooves 12 at the corresponding positions.
[0027] In this embodiment, since notches are usually provided on both sides of the ends of the cable row (similar to a letter-shaped structure), when the cable row is inserted into the interior of the connector body 1 and cannot be pushed, the notch just corresponds to the rectangular groove 11. Therefore, the pressure plate 2 can press the cable row under the elastic action of the two supporting springs 23, and the two plug-in blocks 21 are respectively inserted into the interior of the rectangular groove 11 at the corresponding positions, so that the cable row can be fixed more firmly.
[0028] Embodiment 2
[0029] like Figure 1-6 As shown, in the present embodiment, both ends of the bottom surface of the cover plate 3 are fixedly connected with a stop block 31, a reel 32 is rotatably connected between the two stop blocks 31, a pull rope 33 fixed to the pressure plate 2 is wound and fixed on the outer wall of the reel 32, and torsion springs are arranged between the two ends of the reel 32 and the stop blocks 31 at corresponding positions, both ends of the top surface of the movable plate 5 are fixedly connected with a connecting block 52, a side surface of the connecting block 52 is fixedly connected with an arc block 2 53, both ends of the bottom surface of the cover plate 3 are fixedly connected with an L-shaped contact block 34, both ends of the top surface of the connector body 1 are provided with a rectangular groove 2 13 for sliding of the L-shaped block 4, a supporting spring 2 41 is fixedly connected between the L-shaped block 4 and the rectangular groove 2 13 at the corresponding position, the top surface of the L-shaped block 4 is fixedly connected with an arc block 1 42, and the limiting blocks 14 are fixedly connected at both ends of the inner bottom surface of the connector body 1 and located between the movable plate 5 and the inner side surface of the connector body 1.
[0030] In this embodiment, the line row is first inserted into the interior of the connector body 1, and pushed backward so that the movable plate 5 compresses the multiple supporting springs 3 51 until the movable plate 5 contacts the two limit blocks 14. At this time, the notch at the end of the line row just corresponds to the rectangular groove 11. Then the cover plate 3 is rotated so that the pressure plate 2 presses the line row under the action of the two supporting springs 1 23 at the corresponding positions, and the two plug-in blocks 21 pass through the notch and are inserted into the interior of the rectangular groove 11 at the corresponding positions. However, after the cover plate 3 completely covers the connector body 1, the two abutment blocks 31 contact the top surface of the pressure plate 2, and at this time, the two pull ropes 33 are rolled up on the outer wall of the reel 32 under the action of the two torsion springs, and at the same time, the two contact blocks 34 contact the arc block 2 53. At this time, The cable row is separated. As the cover plate 3 is flipped downward, it will contact with the two arc blocks 42 and push the two arc blocks 42, so that the two L-shaped blocks 4 are moved away from each other. When the cover plate 3 completely covers the connector body 1, the L-shaped block 4 returns to its original position under the action of the supporting springs 41 at the corresponding position and the cover plate 3 is locked. When replacing the cable row, the two L-shaped blocks 4 are moved away from each other and then the cover plate 3 is quickly opened. The two contact blocks 34 can be quickly separated from the two arc blocks 53, and the two pull ropes 33 can be quickly straightened and the pressure plate 2 can be quickly moved up. Then the moving plate 5 quickly returns to its original position under the elastic action of multiple supporting springs 51, so that the cable row can be quickly popped out of the connector body 1.
