Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an FPC connector with an anti-loosening function. Background Art

[0002] FPC connector is an electronic connection device designed for flexible printed circuit boards, used to achieve reliable electrical connection between FPC and other electronic components or rigid printed circuit boards. The connection between traditional FPC connectors and connecting wires is generally connected by snap-on connection. During the use of FPC connectors, the connecting wires are easily affected by external factors, causing looseness or even falling, causing damage to the FPC connector.

[0003] To this end, we propose an FPC connector with an anti-loosening function that can reinforce the connection line. Utility Model Content

[0004] In order to overcome the disadvantage that the connecting wire is easily affected by the outside world and becomes loose or even falls off, the utility model provides an FPC connector with an anti-loosening function which can reinforce the connecting wire.

[0005] An FPC connector with an anti-loosening function includes a moving plate, a fixed frame is slidably connected to the moving plate, and a transversely symmetrical extrusion plate is slidably connected to the moving plate. The fixed frame is slidably connected to the fixed plate, a matching block is fixedly connected to the bottom end of the fixed plate, and equidistantly distributed reset springs are connected between the fixed plate and the fixed frame.

[0006] Further explanation: the top side surface of the fixing plate is a longitudinally symmetrical arc-shaped protruding structure for clamping the connecting wire.

[0007] To further illustrate, the bottom end of the matching block is an arc structure, the side of the extrusion plate close to the matching block is an arc structure, and the extrusion plate is extrusion-matched with the matching block.

[0008] Further description, it also includes a lower pressure plate, which is slidably connected in the fixed frame, and a laterally symmetrical connecting plate is rotatably connected to the lower pressure plate. Two guide rods are fixedly connected in the fixed frame, and a laterally symmetrical sliding plate is slidably connected between the two guide rods. The sliding plate is rotatably connected to the adjacent connecting plate, and a bidirectional screw rod is rotatably connected to the upper part of the fixed frame. The bidirectional screw rod is connected to the sliding plate by threads, and gears are fixedly connected at both ends of the bidirectional screw rod. A laterally symmetrical rack plate is fixedly connected in the movable plate, and the rack plate meshes with the adjacent gears.

[0009] Further explanation: the bottom end of the lower pressure plate is made of rubber material to increase the friction between the lower pressure plate and the connecting line.

[0010] Further description, it also includes a transversely symmetrical threaded sleeve, which is fixedly connected to the bottom end of the fixed frame, and a threaded rod is threadedly connected inside the threaded sleeve.

[0011] The utility model has the following advantages: 1. The connecting wire is inserted between the movable plate and the fixed frame, and then the movable plate is controlled to slide backward. Through the extrusion plate and the matching block, the fixed plate is controlled to slide upward and match with the fixed frame to reinforce the connecting wire and prevent the connecting wire from loosening.

[0012] 2. The rack plate and the gear can drive the bidirectional screw to rotate, thereby controlling the lower pressure plate to slide downward and press on the connecting line, thereby further fixing the connecting line to prevent the connecting line from loosening.

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0022] Embodiment 1: An FPC connector with anti-loosening function, such as Figure 1-Figure 7 As shown, it includes a moving plate 1, a fixed frame 2, an extrusion plate 3, a fixed plate 4, a matching block 5 and a reset spring 6. The moving plate 1 is slidably connected to the fixed frame 2 at the rear, and the moving plate 1 is fixedly connected to a left-right symmetrical extrusion plate 3 at the lower part, and the fixed frame 2 is slidably connected to the fixed plate 4 at the lower part. The front and rear parts of the upper side of the fixed plate 4 are both arc-shaped protruding structures for clamping the connecting line. The lower side of the fixed plate 4 is fixedly connected to the matching block 5, and the lower side of the matching block 5 is an arc structure. The side of the extrusion plate 3 close to the matching block 5 is an arc structure. The extrusion plate 3 is extruded and matched with the matching block 5, and reset springs 6 distributed equidistantly are connected between the fixed plate 4 and the fixed frame 2.

[0023] When using the device, the staff inserts the connecting wire between the movable plate 1 and the fixed frame 2, and then controls the movable plate 1 to slide backward. The movable plate 1 slides backward and drives the extrusion plate 3 to move backward. When the extrusion plate 3 moves backward and contacts with the matching block 5, the extrusion plate 3 continues to move backward to squeeze the matching block 5 to move upward. The matching block 5 moves upward and drives the fixed plate 4 to slide upward. The reset spring 6 is deformed. After the fixed plate 4 slides upward, it cooperates with the fixed frame 2 to reinforce the connecting wire to prevent the connecting wire from loosening. When the movable plate 1 slides forward and opens, the extrusion plate 3 will also move forward and disengage from the matching block 5. At this time, under the action of the reset spring 6, the fixed plate 4 slides downward and resets to loosen the connecting wire. In this way, the connecting wire can be reinforced to prevent the connecting wire from loosening.

[0024] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, it also includes a lower pressure plate 7, a connecting plate 8, a sliding plate 801, a guide rod 9, a bidirectional screw rod 10, a gear 11 and a rack plate 1101. The upper part of the fixed frame 2 is slidably connected to the lower pressure plate 7, and the lower side of the lower pressure plate 7 is made of rubber material, which is used to increase the friction between the connecting line, and the left and right parts of the upper side of the lower pressure plate 7 are rotatably connected to the connecting plate 8, and the upper part of the fixed frame 2 is fixedly connected to two guide rods 9, and a left-right symmetrical sliding plate 801 is slidably connected between the two guide rods 9. The sliding plate 801 is rotatably connected to the adjacent connecting plate 8, and the upper part of the fixed frame 2 is rotatably connected to the bidirectional screw rod 10, and the bidirectional screw rod 10 is threadedly connected to the sliding plate 801, and the left and right parts of the bidirectional screw rod 10 are fixedly connected to the gear 11, and the left and right sides of the movable plate 1 are fixedly connected to the rack plate 1101, and the rack plate 1101 moves backward to mesh with the adjacent gear 11.

[0025] When using the device, the moving plate 1 moves backward and drives the rack plate 1101 to move backward. When the rack plate 1101 moves backward to mesh with the gear 11, the rack plate 1101 continues to move backward to drive the gear 11 to rotate. The rotation of the gear 11 drives the two-way screw rod 10 to rotate. The rotation of the two-way screw rod 10 drives the sliding plate 801 to slide toward each other. The sliding plates 801 slide toward each other and push the lower pressure plate 7 to slide downward through the connecting plate 8. After the lower pressure plate 7 slides downward, it presses above the connecting line, thereby further fixing the connecting line to prevent the connecting line from loosening. When the moving plate 1 slides forward and opens to drive the rack plate 1101 to move forward, the gear 11 will also drive the two-way screw rod 10 to reverse, thereby driving the sliding plate 801 to slide backward. The sliding plate 801 slides backward and pulls the lower pressure plate 7 to slide upward through the connecting plate 8 to reset and release the connecting line.

[0026] like Figure 6 and Figure 7 As shown, it also includes a threaded sleeve 13 and a threaded rod 14. The left and right parts of the lower side of the fixed frame 2 are fixedly connected with the front and rear symmetrical threaded sleeves 13, and the threaded rod 14 is connected to the threaded sleeve 13 through threads.

[0027] When the device is used, the worker can fix the device at a designated position by cooperating with the threaded sleeve 13 and the threaded rod 14 .

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
