Description
Technical Field
[0001] The utility model relates to the field of electric connectors, in particular to a flip-cover type FPC connector. Background Art
[0002] FPC connectors are an essential component of electronic devices, enabling electrical connections and signal transmission between circuits, between circuits and devices, and between devices. 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 FPC connectors achieve the effect of flipping and pressing the circuit board together by using elastic arms on the conductive terminals and a pressure plate. However, because the elastic arms are prone to shaking or even deformation when subjected to vibration or impact, the pressure plate can easily become loose and displaced during use, affecting the stability of the connection between the circuit board and the housing. Therefore, the present utility model proposes a flip-top FPC connector that provides a stable connection and is easy to install. Summary of the Invention
[0004] The utility model provides a flip-cover type FPC connector, which solves the problem that the pressing plate is prone to loosening and displacement during use by means of a fixing assembly that cooperates with each other between a shell and a pressing plate.
[0005] The purpose of this utility model is achieved by the following methods:
[0006] A flip-top FPC connector includes a shell with a rotatable pressure plate mounted on it. The shell is provided with a conductive terminal and a ground terminal that cooperate with the pressure plate. Both sides of the shell are provided with L-shaped grooves. Both sides of the pressure plate are provided with support shafts that cooperate with the L-shaped grooves. The support shafts are provided with step grooves. The ground terminal is provided with a contact portion that cooperates with the step grooves.
[0007] Furthermore, the shell is provided with a guide structure that cooperates with the L-shaped groove.
[0008] Furthermore, the ground terminal is installed on both sides of the shell through a fixing portion, and the shell is provided with a fixing groove that cooperates with the fixing portion.
[0009] Furthermore, a guide portion is provided at one end of the ground terminal.
[0010] Furthermore, the shell and the pressure plate are respectively provided with a slot and a buckle for cooperating with each other.
[0011] Furthermore, a support block is provided at the lower end of the slot.
[0012] Furthermore, a handle is provided on one side of the pressing plate for easy lifting.
[0013] The beneficial effects of this utility model are as follows: the step groove cooperates with the contact portion of the ground terminal to firmly fix the support shaft in the L-shaped groove, making the rotation of the pressure plate more stable and smooth while preventing the pressure plate from loosening and displacement during use. This ensures the stability and reliability of the connection between the circuit board and the electrical connector. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0021] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.
[0022] In this embodiment, refer to Figures 1-6, which specifically implements a flip-top FPC connector, including a shell 1, a rotatable pressure plate 2 is installed on the shell 1, and a conductive terminal 3 and a ground terminal 4 are provided in the shell 1 to cooperate with the pressure plate 2. The conductive terminal 3 cooperates with the pressure plate 2 through a contact arm, so that the pressure plate 2 can be rotatably installed on the shell 1, and L-shaped grooves 5 are provided on both sides of the shell 1. Support shafts 6 that cooperate with the L-shaped grooves 5 are provided on both sides of the pressure plate 2, and a step groove 7 is provided on the support shaft 6. The ground terminal 4 is provided with a contact portion 8 that cooperates with the step groove 7. The design of the L-shaped groove 5 makes it more convenient and quick to install the support shaft 6 into the housing 1, and the support shaft 6 is fixed by inserting the ground terminal 4 into the housing 1, so that the contact portion 8 cooperates with the step groove 7 to firmly fix the support shaft 6 in the L-shaped groove 5. The contact portion 8 adopts an arc surface with the same radius as the step groove 7, so that the ground terminal 4 has a fixing effect without affecting the rotation of the pressure plate 2. At the same time, the step groove 7 is equal to the thickness of the ground terminal 4, which prevents the pressure plate 2 from sliding left and right when subjected to vibration, etc., thereby causing the fixing structure to detach from the housing 1 and affecting the normal use of the connector.
[0023] Furthermore, the housing 1 is provided with a guide structure 9 that cooperates with the L-shaped groove 5. The L-shaped groove 5 has an opening, and the guide structure 9 is inclined upward along the opening, so that when the support shaft 6 is installed in the L-shaped groove 5, it is guided by the guide structure 9 to quickly align with the opening and enter the L-shaped groove 5, thereby achieving fast and accurate installation.
[0024] Furthermore, the ground terminal 4 is mounted on both sides of the housing 1 via fixing portions 10. The housing 1 is provided with fixing slots 11 that cooperate with the fixing portions 10. The cooperation between the fixing portions 10 and the fixing slots 11 ensures that the ground terminal 4 is firmly fixed after being inserted into the housing 1, ensuring that the connection between the ground terminal 4 and the stepped groove 7 will not loosen due to vibration or external forces during use, thereby affecting the stability of the pressure plate 2.
[0025] Furthermore, a guide portion 12 is provided at one end of the ground terminal 4. This guide portion 12 facilitates smoother insertion of the ground terminal 4 into the housing 1, thereby improving assembly efficiency. The tapered design of the guide portion 12 ensures that the ground terminal 4 precisely enters the corresponding position during insertion, allowing the fixing portion 10 to engage with the fixing slot 11.
[0026] Furthermore, the housing 1 and the pressure plate 2 are respectively provided with a slot 13 and a buckle 14 for engaging with each other. The design of the slot 13 and the buckle 14 allows the pressure plate 2 to be firmly fixed to the housing 1 after rotating around the support shaft 6, pressing the circuit board tightly and ensuring that the circuit board will not loosen due to vibration or impact during use.
[0027] Furthermore, a support block 15 is provided at the lower end of the slot 13. The support block 15 can prevent the pressing plate 2 from excessively rotating downward when pressed or subjected to external force, which could cause the ground terminal 4 or the circuit board to be squeezed and deformed, thereby causing poor contact or short circuit.
[0028] Furthermore, a handle 16 is provided on one side of the pressure plate 2 for easy lifting. This handle 16 allows the pressure plate 2 to be easily lifted, disengaging the latch 14 from the slot 13, thereby completing the installation or removal of the circuit board. The handle 16 is integrally formed with the pressure plate 2, providing sufficient strength and durability while reducing installation steps and improving production efficiency.
[0029] The beneficial effects of the present invention are as follows: the step groove 7 cooperates with the contact portion 8 on the ground terminal 4 to firmly secure the support shaft 6 within the L-shaped groove 5, making the rotation of the pressure plate 2 smoother and more stable while preventing the pressure plate 2 from loosening or shifting during use. This ensures stability and reliability between the circuit board and the electrical connector.
[0030] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention is disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the above-disclosed technical contents without departing from the scope of the technical solution of the present invention.
