Grounding springs play a crucial role in FPC connectors. They not only provide an effective grounding path to protect circuits from electromagnetic interference, but also directly impact the stability and reliability of the connection between the FPC connector and the circuit board.

[0003] Existing electrical connectors use a flip-up cover to quickly clamp circuit boards for quick installation and removal. However, since the clamping thickness cannot be adjusted and circuit boards vary in thickness, thicker or thinner boards can easily be damaged or experience poor contact, affecting the connection between the board and the electrical connector and reducing the user experience. Therefore, the present utility model provides an electrical connector with adjustable clamping thickness. Summary of the Invention

[0007] Furthermore, limiting grooves are provided on both sides of the base, and the clamping block is provided with limiting blocks that cooperate with the limiting grooves.

[0008] Furthermore, the limiting block is a T-shaped structure.

[0009] Furthermore, a compression spring is provided between the pressure plate and the base.

[0010] Furthermore, a stop block is provided at one end of the guide shaft.

[0011] Furthermore, a groove is provided on the upper end of the clamping block for easy pushing.

[0012] Advantages of the present utility model: Through the cooperation of the clamping plate that can slide up and down and the base, the clamping thickness of the electrical connector can be flexibly adjusted, so as to adapt to circuit boards of different thicknesses, and the applicable range of the electrical connector is increased. And through the return spring, the block is matched with the ratchet teeth to achieve the effect of quickly clamping or loosening the clamping plate, so as to ensure the stable connection between the electrical connector and the circuit board.

Detailed Description of the Embodiment

[0019] The following further describes the present utility model in detail in conjunction with the drawings and the specific embodiments.

[0020] In this embodiment, refer to Figures 1 - 5, which specifically implements an electrical connector with adjustable clamping thickness, including a base 1, a pressure plate 2, a conductive terminal 3 and a grounding terminal 4. The pressure plate 2 is installed in the base 1 so as to slide up and down through a guide shaft 5. The guide shaft 5 is fixed in the base 1 through a thread and is evenly distributed in a rectangular shape to ensure the stability of the pressure plate 2 when sliding up and down. Sliding clamps 6 are installed on both sides of the base 1. The clamps 6 are installed on both sides of the base 1 through bolts. One end of the bolt is fixed to the clamp 6 through a threaded connection, and cooperates with the base 1 through a step at the other end to limit the sliding range of the clamp 6. A reset spring 7 is provided between the clamp 6 and the base 1. The reset spring 7 is installed on the outside of the bolt to ensure that the clamp 6 can automatically reset during the sliding process. Ratchets 8 are provided on both sides of the pressure plate 2 to cooperate with the clamp 6. The spacing of the ratchet teeth 8 is designed according to the thickness of the circuit board to adapt to circuit boards of different thicknesses. After inserting the circuit board, press the pressure plate 2 downward so that the ratchet 8 squeezes the clamping block 6 to slide outward and compresses the reset spring 7. When the pressure plate 2 comes into contact with the circuit board, the reset spring 7 releases energy and pushes the clamping block 6 to slide inward, so that the ratchet 8 cooperates with the clamping block 6 to fix the position of the clamp, thereby ensuring a stable connection between the electrical connector and the circuit board. When the circuit board needs to be removed, push the clamping blocks 6 on both sides to slide outward and pull the pressure plate 2 upward to easily remove the circuit board.

[0021] Furthermore, the base 1 is provided with limiting grooves 9 on both sides, and the clamping block 6 is provided with limiting blocks 10 that cooperate with the limiting grooves 9. The cooperation between the limiting grooves 9 and the limiting blocks 10 ensures that the clamping block 6 remains stable during the sliding process, avoiding shaking or deviation during the sliding process, which may cause the clamping block 6 to collide with or damage the tooth tips of the ratchet teeth 8, and affect the stability and reliability of the electrical connector.

[0022] Furthermore, the stopper 10 is T-shaped. This T-shaped design ensures high stability when engaged with the stopper slot 9, while also facilitating installation and removal. The shape of the stopper slot 9 matches the T-shaped stopper 10, forming a stable positioning structure that ensures stability in multiple directions. This prevents the clamping block 6 from deviating from its predetermined trajectory during sliding, ensuring the accuracy and reliability of the entire electrical connector.

[0023] Furthermore, a compression spring 11 is installed between the pressure plate 2 and the base 1. This allows the pressure plate 2 to quickly spring upward without manual lifting, thus improving ease of operation. The compression spring 11 is mounted on the outer diameter of the guide shaft 5, ensuring that the pressure plate 2 remains stable during its upward and downward sliding motion. When the pressure plate 2 is pressed downward, the compression spring 11 is compressed. When the clamping block 6 pushes outward, releasing the ratchet 8, the compression spring 11 releases energy, pushing the pressure plate 2 upward rapidly, releasing the circuit board.

[0024] Further, one end of the guiding shaft 5 is provided with a stop block 12. The function of the stop block 12 is to limit the excessive upward movement of the pressing plate 2, ensure that it remains within a predetermined range during the sliding process, prevent the pressing plate 2 from detaching from the base 1, and thus guarantee the normal operation of the electrical connector.

[0025] Further, the upper end of the clamping block 6 is provided with a groove 13 for easy pushing. The design of the groove 13 simplifies the operation process of pushing the clamping block 6, making the operation more convenient. The user can easily slide the clamping block 6 outwards with a finger or a tool, thereby quickly releasing the pressing plate 2 and facilitating the disassembly of the circuit board.

[0026] The beneficial effects of the present utility model are as follows: Through the cooperation of the slidable clamping plate and the base 1, the clamping thickness of the electrical connector can be flexibly adjusted, so as to adapt to circuit boards of different thicknesses, and the applicable range of the electrical connector is increased. And through the return spring 7, the engagement between the locking block and the ratchet 8 is realized to achieve the effect of quickly clamping or releasing the clamping plate, so as to ensure the stable connection between the electrical connector and the circuit board.

[0027] The above are only preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model is disclosed above in a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art, without departing from the scope of the technical solution of the present utility model, when making some changes or modifications to the above-disclosed technical content to obtain equivalent embodiments with equivalent changes, as long as the content of the technical solution of the present utility model is not departed from, any simple modification, equivalent change and modification made to the above embodiments according to the technical concept of the present utility model shall fall within the scope of the technical solution of the present utility model.
