Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an FPC connector with a double-row terminal structure. Background Technology

[0002] As electronic products become thinner, lighter, and denser, FPCs are widely used due to their flexibility and small size. Correspondingly, FPC connectors also need to achieve more signal transmission within a limited space. Traditional single-row FPC connectors have a limited number of contact points, making it difficult to meet the demands of high-bandwidth signal transmission. Existing dual-row FPC connectors mostly use a simple top-to-bottom aligned layout, making it difficult to further reduce the terminal pitch, thus limiting the improvement of connector density. Utility Model Content

The connecting part is also provided with a lower row elastic lever arm located below the lower row terminal upper pressure rod. The front end of the lower row elastic lever arm is also provided with a second terminal contact point.

[0010] Preferably, the upper row of contact terminals and the lower row of contact terminals are respectively provided with terminal locking points, and the plastic body is provided with corresponding hole structures. The terminal locking points cooperate with the hole structures to fix and position the upper row of contact terminals and the lower row of contact terminals.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0025] like Figures 1-8 As shown, this embodiment provides an FPC connector with a dual-row terminal structure, which mainly includes a plastic body 1, an upper row of contact terminals 2, a lower row of contact terminals 3, and a rotating top cover 4.

[0026] The plastic body 1 is made of insulating engineering plastic. A first mounting slot 5 is formed on its front side for mounting the lower row of contact terminals 3; a second mounting slot 6 is formed on its rear side for mounting the upper row of contact terminals 2. The first mounting slots 5 and the second mounting slots 6 are spatially staggered, not vertically aligned, forming a staggered three-dimensional layout. By designing the mounting slots of the upper and lower rows of terminals in a staggered three-dimensional layout, interference between terminals is effectively reduced, allowing more terminals to be arranged within a smaller spacing, thus meeting the high-density integration requirements of electronic products.

[0027] The upper row of contact terminals 2 is formed by stamping. It has an upper row terminal pressing rod 201 at the top and an upper row elastic lever 202 in the middle. The front end of the upper row elastic lever 202 has a first terminal contact point 203. Terminal locking points 7 are also stamped on the terminal body.

[0028] The lower row of contact terminals 3 has a unique structure, including a strip-shaped terminal body 301. The insertion end of the terminal body 301 is bent upward to form a vertical connecting part 302. The upper part of the connecting part 302 extends forward to form a lower row terminal upper pressure rod 304, and the lower part of the connecting part 302 extends forward to form a lower row elastic lever arm 305. The front end of this lever arm is provided with a second terminal contact point 303, which facilitates the assembly of the lower row of contact terminals 3. The lower row of contact terminals 3 is also provided with terminal locking points 7. Both the upper and lower rows of terminals have independent elastic lever arms and contact points, which can stably press the conductors on the upper and lower surfaces of the FPC, ensuring the reliability of the electrical connection.

[0029] This invention utilizes upper and lower elastic arms to press the FPC from both top and bottom directions, providing a stable connection between the conductors on both sides of the FPC (i.e., double-sided copper-clad FPC) and ensuring reliable electrical connection. During assembly, the upper row of contact terminals 2 is pressed into the second mounting groove 6, the lower row of contact terminals 3 is pressed into the first mounting groove 5, and the terminal locking points 7 are engaged with the corresponding holes on the plastic body 1, achieving secure fixing and precise positioning.

[0030] The rotating top cover 4 has a rotating shaft 11 at its lower part, and a shaft groove 9 corresponding to the lower row of contact terminals 3 is provided to mate with the rotating shaft 11. During assembly, the rotating shaft 11 is pressed into the shaft groove 9 to achieve a rotatable connection with the lower row of contact terminals 3. Rotation and opening / closing is the most important mechanical action of the connector, and long-term use will cause wear at the contact point between the shaft and the groove. By placing the shaft groove on the metal terminal, the problems of rotational loosening, abnormal noise, or even failure caused by plastic wear can be completely avoided. The metal terminal is formed by stamping, with extremely high dimensional accuracy. The rotating pair is directly composed of metal parts, and its fitting clearance can be controlled to be smaller and more consistent, avoiding dimensional fluctuations caused by plastic shrinkage or deformation under stress. This makes the opening and closing action of the rotating top cover smoother and more stable, without any shaking; when the rotating top cover is closed, the downward pressure is directly transmitted to the rotating shaft of the metal terminal through the top cover, and then the force is finally applied to the FPC through the metal terminal itself. This force transmission path is completed entirely within or between the metal parts, forming a very direct and robust mechanical structure. This reduces the stress on the plastic body and lowers the risk of long-term stress creep. The rotating top cover 4 is also provided with upper row terminal blind holes 14, lower row terminal through holes 15 and limiting R angle 12.

[0031] Operating Procedure: When an FPC needs to be inserted, rotate the top cover 4 upwards to open it. At this time, both the upper row elastic arms 202 and the lower row elastic arms 305 are in the released state, leaving space for the insertion of the FPC. Insert the FPC into the connector socket in the correct direction. Then rotate the top cover 4 to close it. During this process: the inner wall of the top cover 4 presses down on the upper row terminal pressure rod 201 through the upper row terminal blind hole 14, causing it to move downwards. This forces the upper row elastic arms 202 to undergo elastic deformation, and the first terminal contact point 203 at its front end presses firmly against the conductor on the upper surface of the FPC with a certain pressure.

[0032] At the same time, the closing action of the rotating top cover 4 will press down the lower row terminal upper pressure rod 304 through its structure (the movement trajectory of the lower row terminal upper pressure rod 304 avoids the lower row terminal through hole 15), thereby driving the lower row elastic lever arm 305 to undergo elastic deformation, and the second terminal contact point 303 at its front end is pressed tightly against the conductor on the lower surface of the FPC with a certain pressure.

[0033] When the top cover 4 is fully closed, its limiting R-angle 12 engages with the elastic top block 13 on the plastic body 1, producing a "click" positioning feel and locking the top cover in the closed position. At this point, the upper and lower surfaces of the FPC are stably pressed together by two rows of staggered terminals, achieving a reliable electrical connection.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
