Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a flexible flat cable connector with anti-detachment function. Background Technology

[0002] Flexible flat cables include FPC and FFC. The two sides of the insertion end of the flexible flat cable are usually provided with anti-detachment grooves. The anti-detachment grooves are used to match the anti-detachment hooks to prevent the flexible flat cable from falling off after being inserted into the connector, thus ensuring the reliability of the connection. The connector needs to be soldered to the PCB board. With the development of automation technology, PCB board soldering is mostly done automatically by automated equipment.

[0003] In a Chinese patent for a flexible flat cable connector (CN215869945U), the device includes a base, terminals, a cover, and positioning solder pads. The cover is rotatably mounted at a slot in the base. The terminals are inserted into the sockets of the base and have limiting arms. Positioning solder pads are mounted at both ends of the base, and the upper part of the positioning solder pads has notches. The notches cooperate with the corresponding sidewalls on the base to form an upward-opening U-shaped shaft groove. The cover has a connecting shaft that extends into the U-shaped shaft groove, and the outer end of the connecting shaft is connected to the cover as a single unit via a connector. The rear of the cover is provided with... The device has a limiting shaft and a limiting arm with a groove that mates with the limiting shaft. The limiting shaft is coaxially arranged with the connecting round shaft. Through the setting of the connecting body and the matching of the groove on the limiting shaft and the limiting arm, the device can effectively prevent the connecting round shaft from breaking, ensure reliable installation of the cover, and thus ensure the reliability of the electrical connection between the flexible flat cable connector and the flexible flat cable. However, the cover of this device is only fixedly connected to the base by pressing and snapping, without a locking mechanism. In daily use, the cover is easily opened by external force, which affects the reliability of the connection to the flexible flat cable. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a flexible flat cable connector with an anti-detachment function. By setting a limiting mechanism, the displacement of the flip cover is limited, thereby preventing the flip cover from opening due to external force during subsequent use, avoiding detachment of the flexible flat cable from the terminal, and ensuring a reliable connection. This solves the problem in the background art where the flip cover of the device is only fixedly connected to the base by pressing and snapping without a locking mechanism, making it easy for the flip cover to open due to external force during daily use, thus affecting the reliability of the connection of the flexible flat cable.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a flexible flat cable connector with anti-derailment function, comprising: a base body, terminals, positioning welding pieces and a flip cover, wherein the terminals are fixed on the inner bottom wall of the base body, the two positioning welding pieces are respectively snapped into the bottom ends of the base body, the flip cover is rotatably mounted on the base body, and two symmetrically arranged limiting mechanisms are fixedly connected to the two ends of the upper side wall of the base body, and the two limiting mechanisms are respectively abutted against the two ends of the upper side wall of the flip cover;

[0006] The limiting mechanism includes a fixed shell fixed to one end of the upper side wall of the base body. A slider is slidably connected to the inner wall of the fixed shell. A T-shaped push block is fixedly connected to the upper end of the slider. A sliding opening is provided on the upper side wall of the fixed shell. The upper end of the T-shaped push block extends outward through the sliding opening. A moving rod is fixedly connected to one side of the slider. One end of the moving rod extends to the outside of the fixed shell and is fixedly connected to a connecting frame. A pressure block is fixedly connected to one end of the connecting frame. A compression spring is fixedly connected between the slider and the inner wall of the fixed shell. The compression spring is sleeved on the outside of the moving rod.

[0007] Preferably, the lower front end of the pressure block is provided with a protrusion, which is abutted against the upper side wall of the cover.

[0008] Preferably, one end of the fixed shell has a through hole, the moving rod passes through the through hole, and the inner wall of the through hole is slidably connected to the outer wall of the moving rod.

[0009] Preferably, the inner walls on both sides of the sliding opening are slidably connected to the side walls on both sides of the vertical section of the T-shaped push block.

[0010] Preferably, both ends of the bottom of the base body are provided with positioning grooves corresponding to the two positioning welding pieces, and the two positioning welding pieces are engaged in the two positioning grooves.

[0011] Preferably, both ends of the flip cover are fixedly connected to a rotating shaft, and both ends of the base body have rotating grooves on their inner walls, with the two rotating shafts rotatably connected to the two rotating grooves respectively.

[0012] The beneficial effects of this utility model are as follows:

[0013] In this invention, by setting a limiting mechanism, when it is necessary to lift the cover to install the flexible flat cable and the connector of this device, firstly, the T-shaped push block is moved to drive the slider to move in the fixed shell.

Then, the cover can be lifted to connect the flexible flat cable and the terminal. Then, the cover is pressed to press and fix the connector end of the flexible flat cable to the terminal. Then, the T-shaped push block is released. At this time, the elastic force of the compression spring causes the pressure block to automatically reset, limiting the displacement of the cover, thereby preventing the cover from opening due to external force during subsequent use, avoiding the flexible flat cable from detaching from the terminal, and ensuring the reliability of the connection.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this embodiment provides a flexible flat cable connector with anti-drop-off function, including: base body 1, terminal 2, positioning welding piece 3 and flip cover 4. When the flexible flat cable is connected to terminal 2, the flip cover 4 is pressed and snapped to the base body 1 for fixation. This is an existing technology device, so it will not be explained in detail here. Terminal 2 is fixed on the inner bottom wall of base body 1. Two positioning welding pieces 3 are respectively snapped to the bottom two ends of base body 1. The positioning welding pieces 3 are welded and fixed to the circuit board. The flip cover 4 is rotatably set on base body 1. Two symmetrically arranged limiting mechanisms are fixedly connected to the two ends of the upper side wall of base body 1. The two limiting mechanisms are respectively abutted against the two ends of the upper side wall of flip cover 4.

[0022] The limiting mechanism includes a fixed shell 8 fixed to one end of the upper side wall of the base body 1. A slider 9 is slidably connected to the inner wall of the fixed shell 8. A T-shaped push block 10 is fixedly connected to the upper end of the slider 9. A sliding opening 11 is provided on the upper side wall of the fixed shell 8. The upper end of the T-shaped push block 10 extends outward through the sliding opening 11. A moving rod 12 is fixedly connected to one side of the slider 9. One end of the moving rod 12 extends to the outside of the fixed shell 8 and is fixedly connected to a connecting frame 13. A pressure block 14 is fixedly connected to one end of the connecting frame 13. A compression spring 15 is fixedly connected between the slider 9 and the inner wall of the fixed shell 8. The compression spring 15 is sleeved on the outside of the moving rod 12. When it is necessary to lift the cover 4 to install the flexible cable and the connector of this device. First, by moving the T-shaped pusher 10, the slider 9 is displaced within the fixed housing 8. This displaces the connecting frame 13, which is fixed to the moving rod 12. At this time, the compression spring 15 is compressed and contracts, generating elastic force until the pressure block 14 and the cover 4 are completely separated. Then, the cover 4 can be lifted to connect the flexible flat cable to the terminal 2. Next, the cover 4 is pressed to press and fix the connector end of the flexible flat cable to the terminal 2. Then, the T-shaped pusher 10 is released. At this time, the elastic force of the compression spring 15 causes the pressure block 14 to automatically reset, limiting the displacement of the cover 4. This prevents the cover 4 from opening due to external force during subsequent use, avoids the flexible flat cable from detaching from the terminal 2, and ensures the reliability of the connection.

[0023] The lower front end of the pressure block 14 is provided with a protrusion 16, which is pressed against the upper side wall of the cover 4 to ensure that the protrusion 16 of the pressure block 14 can press the cover 4 tightly, thereby ensuring the firmness of the connection of the flexible flat cable.

[0024] One end of the fixed shell 8 has a through hole, through which the moving rod 12 passes. The inner wall of the through hole is slidably connected to the outer wall of the moving rod 12, which facilitates the displacement of the moving rod 12.

[0025] The inner walls on both sides of the sliding opening 11 are slidably connected to the side walls on both sides of the vertical section of the T-shaped push block 10, which facilitates pushing the T-shaped push block 10.

[0026] The base body 1 has positioning grooves 5 at both ends of its bottom, which correspond to the two positioning welding pieces 3. The two positioning welding pieces 3 are snapped into the two positioning grooves 5, and the snap-fit ​​connection is convenient for disassembly.

[0027] Both ends of the flip cover 4 are fixedly connected to rotating shafts 6, and both ends of the base body 1 are provided with rotating grooves 7. The two rotating shafts 6 are rotatably connected to the two rotating grooves 7 respectively, so that the flip cover 4 can rotate easily on the base body 1.

[0028] The principle of this embodiment is as follows: When it is necessary to lift the cover 4 to install the flexible flat cable and the connector of this device, firstly, the T-shaped push block 10 is moved to drive the slider 9 to move in the fixed shell 8. At this time, the connecting frame 13 fixed to the moving rod 12 is moved. At this time, the compression spring 15 is squeezed and contracted to generate elastic force until the pressure block 14 is completely separated from the cover 4. At this time, the cover 4 can be lifted to connect the flexible flat cable to the terminal 2. Then, the cover 4 is pressed to press and fix the connector end of the flexible flat cable to the terminal 2. Then, the T-shaped push block 10 is released. At this time, the elastic force of the compression spring 15 is used to make the pressure block 14 automatically reset, and the displacement limit of the cover 4 is performed, thereby preventing the cover 4 from being opened by external force during subsequent use, avoiding the flexible flat cable from detaching from the terminal 2, and ensuring the reliability of the connection.
