Description

Technical Field

[0001] The utility model relates to the field of electric connectors, in particular to a flip-cover self-locking connector. Background Art

[0002] FPC connectors are an essential component of electronic devices, ensuring electrical connections and signal transmission between circuits, between circuits and devices, and between devices. FPC connectors come in various styles, including flip-top and drawer types, allowing users to choose the right connector for their needs. Flip-top connectors securely secure circuit boards within their housings through the mating of a pressure plate with conductive and grounding terminals, ensuring a stable connection. This ensures that signals on the circuit board are accurately transmitted to other circuits or devices.

[0003] Existing connectors use a clip and a slot to securely clamp the circuit board between the housing and the pressure plate. However, since the pressure plate lacks a fixing component after compression, the clip and slot can easily become loose when subjected to external impact or vibration, causing the pressure plate to loosen, resulting in poor contact or even detachment of the circuit board, affecting the normal operation of the device. Therefore, the present invention proposes a flip-top, self-locking connector with a fixing component. Summary of the Invention

[0004] The utility model provides a flip-cover self-locking connector, which solves the problem of poor contact or easy falling off of a circuit board during use by respectively arranging mutually matching fixing components on a shell and a pressure plate.

[0007] Furthermore, both ends of the pressure plate are provided with limit blocks, and the ratchet is provided with limit grooves that cooperate with the limit blocks.

[0008] Furthermore, clamps for fixing the ratchet are installed at both ends of the pressure plate.

[0009] Furthermore, the reset assembly includes a connecting plate, a positioning pin and a reset spring. The connecting plate is slidably installed on one side of the shell through the positioning pin. The reset spring is arranged between the shell and the connecting plate. One side of the connecting plate is provided with a mounting plate that is connected and cooperated with the pawl.

[0010] Furthermore, the connecting plate is provided with a waist-shaped hole that cooperates with the positioning pin.

[0011] Furthermore, a fixing groove is provided through one side of the mounting plate for limiting the left and right sliding of the pawl.

[0012] Furthermore, the fixing groove is provided with a guide structure for facilitating the installation of the pawl.

[0013] The beneficial effects of this utility model are as follows: the pawl and ratchet cooperate to achieve a one-way locking effect on the pressure plate, firmly securing it and preventing it from loosening under external impact or vibration, which could affect the stable connection between the connector and the circuit board.

DETAILED DESCRIPTION

[0022] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0023] In this embodiment, refer to Figure 1-Figure 7The invention specifically implements a flip-top self-locking connector, which includes a housing 1 and a rotatable pressure plate 2 mounted on the housing 1. A buckle and a slot are provided between the pressure plate 2 and the housing 1. A conductive terminal 3 and a ground terminal 4 are provided in the housing 1 to cooperate with the pressure plate 2. Ratchets 5 are provided at both ends of the pressure plate 2. The housing 1 is equipped with a pawl 6 to cooperate with the ratchet 5. One end of the pawl 6 is connected to a reset assembly. The pawl 6, the ratchet 5, and the reset assembly cooperate to achieve the effect of one-way locking of the pressure plate 2. When the pressure plate 2 rotates downward, the buckle cooperates with the slot to firmly press the circuit board. The reset assembly makes the pawl 6 firmly close to the ratchet 5, so that the ratchet 5 and the pawl 6 engage with each other to firmly lock the pressure plate 2 in the compressed state, avoiding the buckle and the slot from loosening under external impact or vibration, causing the pressure plate 2 to loosen and affecting the stable connection between the circuit board and the conductive terminal 3. When the pressing plate 2 needs to be opened, the reset assembly is pressed to lift the pawl 6, release the ratchet 5, and then the pressing plate 2 is lifted upward to separate the buckle from the slot, thereby lifting the pressing plate 2 and releasing the circuit board.

[0024] Furthermore, limit blocks 7 are provided at both ends of the pressure plate 2, and the ratchet 5 is provided with limit slots 8 that cooperate with the limit blocks 7. The cooperation between the limit blocks 7 and the limit slots 8 ensures that the ratchet 5 can rotate as the pressure plate 2 rotates. At the same time, it prevents the ratchet 5 from slipping, which could affect its cooperation with the pawl 6.

[0025] Furthermore, clamps 9 are mounted on both ends of the pressure plate 2 to secure the ratchet 5. Stepped grooves are provided at both ends of the pressure plate 2 to mate with the clamps 9. The clamps 9 and the stepped grooves cooperate to quickly secure the ratchet 5, facilitating installation while reducing production costs and improving efficiency. The clamps 9 are made of a high-strength, high-toughness plastic material, ensuring they can withstand significant pressure and tension during use without deformation or breakage. This prevents the clamps 9 from breaking and causing the ratchet 5 to loosen.

[0026] Furthermore, the reset assembly includes a connecting plate 10, a positioning pin 11, and a reset spring 12. The connecting plate 10 is slidably mounted on one side of the housing 1 via the positioning pin 11. The reset spring 12 is positioned between the housing 1 and the connecting plate 10. A mounting plate 13 is provided on one side of the connecting plate 10, which engages with the pawl 6. The positioning pin 11 is threadedly secured to the housing 1. A stepped shaft at one end of the positioning pin 11 limits the sliding distance of the connecting plate 10. The reset spring 12 pushes the connecting plate 10 upward, causing the mounting plate 13 to rotate the pawl 6 and engage the ratchet 5. The mounting plate 13 and the pawl 6 are connected by a latch.

[0027] Furthermore, the connecting plate 10 is provided with a waist-shaped hole 14 that mates with the locating pin 11. The design of the waist-shaped hole 14 provides greater flexibility during adjustment or installation of the connecting plate 10. This design allows the connecting plate 10 to move freely within a certain range. Furthermore, the shape of the waist-shaped hole 14 conforms to the diameter of the locating pin 11, ensuring smooth and accurate movement of the connecting plate 10.

[0028] Furthermore, a fixing slot 15 is provided through one side of the mounting plate 13 to limit the left and right sliding of the pawl 6. The connection end of the pawl 6 is sized to fit the fixing slot 15. By snapping the pawl 6 into the fixing slot 15 and securing it with a latch, the pawl 6 is prevented from sliding left and right during use, thereby preventing it from affecting its connection with the ratchet 5, thereby significantly improving the stability and efficiency of the device.

[0029] Furthermore, the fixing slot 15 is provided with a guide structure 16 that facilitates the installation of the pawl 6. The design of the guide structure 16 improves the accuracy of the pawl 6 when it is inserted into the fixing slot 15. The fit between the guide structure 16 and the pawl 6 promotes a smooth fit between the pawl 6 and the fixing slot 15, preventing loosening or falling off caused by improper installation. This sophisticated design not only enhances the structural stability, but also makes installation more convenient and quick, improving work efficiency.

[0030] The beneficial effects of this utility model are as follows: the pawl 6 cooperates with the ratchet 5 to achieve a one-way locking effect on the pressure plate 2, firmly securing the pressure plate 2 and preventing it from loosening under external impact or vibration, which could affect the stable connection between the connector and the circuit board. At the same time, by controlling the up and down sliding of the reset assembly, the pawl 6 can flexibly disengage or press the ratchet 5, achieving the effect of releasing or securing the pressure plate 2, thereby improving work efficiency and ease of operation.
