Abstract
Description
Technical Field
[0001] This utility model relates to connectors, and more particularly to anti-loosening FPC connectors. Background Technology
[0002] FPC connectors, or flexible flat cable connectors, are interface devices specifically designed to connect flexible printed circuit boards (PCBs) to other electronic components or circuit boards. In modern smart TVs, to achieve multiple functions such as high-definition video signal transmission, touchscreen control, and audio output, the motherboard and display screen are typically connected via one or more multi-pin connectors. These connectors not only transmit large amounts of data signals but also provide power and ground connections.
[0003] Traditional multi-pin FPC connectors typically rely on snaps or simple fixing structures on the housing to hold the terminals in place. As the number of pins increases, the fixing support for each terminal decreases, making the terminals prone to shifting and resulting in a loose overall structure. Utility Model Content
[0004] In order to overcome the shortcomings of traditional multi-PIN FPC connectors, which weaken the fixing support of the terminals as the number of PINs increases, making them prone to displacement and thus making the overall structure loose, this utility model can provide an anti-loosening FPC connector.
[0005] Technical Solution: An anti-loosening FPC connector includes a plastic body, terminals, a flip cover, protrusions, oval blocks, and fixing plates. The plastic body has several through slots, each containing a terminal. A flip cover is located on the top of the plastic body, with oval blocks at both ends. The flip cover has several grooves, each containing a protrusion. The front and back of the protrusion are the longer portions, while the top and bottom surfaces are the shorter portions. The terminals have through holes and openings; the opening of the terminal is smaller than the through hole. The longer portion of the protrusion is larger than the opening of the terminal but smaller than the through hole, and the shorter portion of the protrusion is smaller than the opening of the terminal. Cavities are located on both sides of the plastic body, each containing a fixing plate with hooks.
[0006] Furthermore, it is particularly preferred that the opening of the terminal has a bevel.
[0007] Furthermore, it is particularly preferred that the device also includes a pressure plate, with the pressure plate provided at the right end of the fixing plate.
[0008] In addition, it is particularly preferred that a handle is included, with the handle located in the center of the cover.
[0009] In addition, it is particularly preferred that the cover also includes locking blocks, with locking blocks provided on both the left and right ends.
[0010] Furthermore, it is particularly preferred that the device also includes a pull tab, with the pull tab located at the bottom of the fixing plate.
[0011] Each protrusion on the flip cover of this utility model has a protrusion that fixes a terminal, so that even if there are a large number of terminals, the structural strength of this connector can still be guaranteed. Attached Figure Description

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0023] Anti-loosening FPC connectors, such as Figures 1-9As shown, the device includes a plastic body 2, terminals 3, a hinged cover 4, protrusions 404, elliptical blocks 401, and a fixing piece 5. The plastic body 2 has several through slots 201, each containing a terminal 3. A hinged cover 4 is located on the top of the plastic body 2. Elliptical blocks 401 are located at both ends of the hinged cover 4. Several grooves 403 are formed on the hinged cover 4, each containing a protrusion 404. The front and rear ends of the protrusion 404 form a long portion 406, and the top and bottom surfaces of the protrusion 404 are... The short portion 407 has a through hole 301 and an opening on the terminal 3. The opening of the terminal 3 is smaller than the through hole 301. The long portion 406 of the protrusion 404 is larger than the opening of the terminal 3 and smaller than the through hole of the terminal. The short portion 407 of the protrusion 404 is smaller than the opening of the terminal 3. The plastic body 2 has cavities 202 on both sides. The position of the cavity 202 corresponds to the elliptical block 401. A fixing piece 5 is provided in the cavity 202. The fixing piece 5 has a hook 501. The hook 501 is used to fix the elliptical block 401.
[0024] like Figure 4 As shown, the opening of terminal 3 is provided with a bevel 302, which can serve as a guide when circuit board 1 is inserted.
[0025] like Figure 7 As shown, it also includes a pressure plate 502. The right end of the fixing plate 5 is provided with a pressure plate 502. When the circuit board 1 is inserted into this connector, the edge of the circuit board 1 will contact the pressure plate 502. The pressure plate 502 is squeezed and interacted with the circuit board 1 to fix the circuit board 1.
[0026] like Figure 1 As shown, it also includes a handle 402. The handle 402 is located in the middle of the cover 4, and the user can easily lift or close the cover 4 by holding the handle 402.
[0027] like Figure 7 As shown, it also includes a locking block 405. The left and right ends of the flip cover 4 are provided with locking blocks 405. Both locking blocks 405 are located between the flip cover 4 and the plastic body 2. The locking blocks 405 are made of elastic material. The design of the locking blocks 405 allows the flip cover 4 to be firmly fastened to the plastic body 2, further enhancing the stability of the flip cover 4.
[0028] like Figure 7 As shown, it also includes a pull tab 503. The bottom of the fixing piece 5 is provided with a pull tab 503. When it is necessary to remove the fixing piece 5, the pull tab 503 can be pulled to remove the fixing piece 5 from the cavity 202, which simplifies the disassembly process and improves the user experience.
[0029] Insert several terminals 3 into the through slots 201 on the plastic body 2 respectively. Stand the flip cover 4 upright and place it on top of the plastic body 2. Align the groove 403 on the flip cover 4 with the terminal 3. At this time, the short part 407 of the protrusion 404 is aligned with the opening of the terminal 3. Insert the flip cover 4 into the through hole 301 on the terminal 3. Then rotate the flip cover 4 so that the long part 406 of the protrusion 404 is aligned with the opening of the terminal 3, so that the flip cover 4 is fixed in the through hole 301 of the terminal 3. The terminal 3 is also fixed in the through slot 201 of the plastic body 2 by the restriction of the flip cover 4. Then insert the circuit board 1 to connect the circuit board 1 with the terminal 3. Finally, insert the fixing piece 5. While the fixing piece 5 is embedded in the cavity 202 on the plastic body 2, the elliptical block 401 is squeezed by the hook 501 to further fix the flip cover 4.
[0030] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
