Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a 0.2Pitch 0.95H front-insertion, front-flipping external FPC connector, suitable for signal connection scenarios of miniaturized electronic devices such as smartphones, tablets, and wearable devices. Background Technology

[0002] Existing front-mounted, front-opening FPC connectors have the following drawbacks: 1. The cover assembly relies on a hard interference method, making the end posts prone to breakage, especially in products with a small pin count; 2. There is a conflict between the cover's locking force and the ribbon cable's holding force, which can easily lead to poor conductivity or cover damage in products with a large pin count; 3. Over-reliance on material properties, with unstable gap values ​​in the open or unsecured state, making ribbon cable insertion difficult; 4. The cover is prone to loosening, causing SMT placement misalignment; 5. The ribbon cable is not securely fixed and is prone to detachment; 6. The product height and spacing are relatively large, failing to meet the miniaturization and high-density integration requirements of electronic devices.

[0003] Therefore, it is necessary to design a 0.2Pitch 0.95H front-mounted, front-flipping external FPC connector to solve the problems mentioned above. Utility Model Content

[0004] This invention aims to solve the problems of existing front-pitch, front-flip FPC connectors, such as easy breakage of the pillar due to hard interference during cover assembly, contradiction between cover fastening force and ribbon cable holding force, SMT placement misalignment caused by cover loosening, easy detachment of ribbon cables, and product size not meeting the miniaturization requirements of electronic devices. It provides a 0.2Pitch 0.95H front-pitch, front-flip external snap-fit ​​FPC connector, which improves assembly stability, connection reliability and size adaptability through structural optimization.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A 0.2Pitch 0.95H front-mounted, front-flip external snap-fit ​​FPC connector includes a connector body, a cover, terminals, a plastic shell, and a ribbon cable locking structure.

[0006] Furthermore, the connector body height is 0.95mm, the terminal spacing is 0.2mm, and it is equipped with a pin groove to accommodate the terminal, a slide groove for mounting the cover, and a cable insertion cavity. The inner wall of the pin groove is provided with raised ribs that fit tightly against the side of the terminal to prevent the terminal from shaking during insertion and removal, and to ensure stable contact impedance.

[0007] Furthermore, the plastic shell has slots on both sides, and the outer sides of the lid have protrusions that cooperate with the slots. When fastened, the protrusions engage with the slots to form a locking structure, preventing the lid from becoming loose.

[0008] Furthermore, the convex surface is provided with anti-slip texture, which creates friction with the inner wall of the slot, further enhancing the stability of the lock and preventing the cover from loosening under vibration.

[0009] Furthermore, the cover has a pivot in the middle that mates with the terminal. The gap is 0.30mm when the cover is open and 0.15mm when the cover is closed. This size difference allows the bottom of the cover to press down on the ribbon cable and make contact with the terminal.

[0010] Furthermore, the terminal includes an upper arm and a lower spring arm. The upper arm cooperates with the hinge of the cover. When fastened, it generates a downward force through deformation, so that the ribbon cable contacts and conducts through the lower spring arm. A transition arc structure is provided between the upper arm and the lower spring arm to disperse stress, prevent the terminal from breaking due to repeated deformation, and improve durability.

[0011] Furthermore, the ribbon cable locking structure includes two protrusions located at the ribbon cable port position on the ribbon cable insertion cavity. When the ribbon cable is inserted, the protrusions cooperate with the grooves on the ribbon cable to lock it in place and prevent the ribbon cable from coming loose.

[0012] Furthermore, the connector body is made of LCP plastic material, and the terminals are made of gold-plated phosphor bronze, ensuring that the materials have good high temperature resistance, conductivity and wear resistance.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a 0.2Pitch 0.95H front-mounted, front-flip external snap-fit ​​FPC connector, achieving the following effects: 1. The 0.2mm ultra-small terminal pitch and 0.95mm low height design significantly reduce space occupation compared to conventional products, adapting to the high-density integration requirements of miniaturized electronic devices such as smartphones and wearable devices; 2. The locking structure of the cover protrusion and the plastic shell slot, combined with anti-slip texture, solves the problem of cover loosening and misalignment during SMT mounting, while avoiding cover breakage caused by traditional hard interference assembly, reducing assembly defect rate; 3. The cooperation between the terminal and the pin groove ribs ensures stable contact impedance; the ribbon cable locking structure, through the cooperation of the boss and the groove, ensures that the ribbon cable pull-out force meets the standard and prevents loosening; the terminal transition arc structure improves durability and can withstand 60 cycle tests; 4. By optimizing the assembly method of the cover and the body and the stress dispersion design of the terminals, the risk of component breakage is reduced, the over-reliance on material properties is reduced, and the product lifespan is extended.

[0019] Please see Figure 2 and Figure 3 This embodiment, based on embodiment 1, further limits the height of the connector body 1 to 0.95mm and the spacing between the terminals 3 to 0.2mm. It is made of LCP plastic material, which has high temperature resistance and deformation resistance. Internally, it has a pin groove 6 for accommodating the terminals 3, a sliding groove for mounting the cover 2, and a cable insertion cavity 7 for inserting the ribbon cable. The inner wall of the pin groove 6 has 0.02mm raised ribs that fit tightly against the side of the terminals 3, preventing the terminals 3 from shaking during insertion and removal, and ensuring stable contact impedance. Example 3

[0020] Please see Figure 2and Figure 5 Based on Embodiment 1, this embodiment further specifies that the plastic shell 4 has slots 8 on both sides, and the outer periphery of the cover 2 has protrusions 9 that cooperate with the slots 8. When fastened, the protrusions 9 are engaged with the slots 8 to form a locking structure. The surface of the protrusions 9 has anti-slip textures with a depth of 0.1mm, which form friction with the inner wall of the slots 8 to prevent the cover 2 from loosening under vibration. The cover 2 has a rotating shaft 10 in the middle that cooperates with the terminal 3. The gap is 0.30mm when the cover is open and 0.15mm when the cover is closed. The size difference allows the bottom of the cover 2 to press against the ribbon cable, making it conductive with the contact point 31 on the terminal 3. Example 4

[0021] Please see Figure 2 Based on Example 1, this embodiment further specifies that terminal 3 is made of gold-plated phosphor bronze and includes an upper arm and a lower spring arm. The upper arm cooperates with the rotating shaft 10 and generates a downward force through deformation when fastened, so that the ribbon cable contacts and conducts through the lower spring arm. A transition arc structure is provided between the upper arm and the lower spring arm to disperse stress and improve durability. Example 5

[0022] Please see Figure 2 and Figure 3 Based on embodiment 1, this embodiment further defines the cable locking structure 5 as including two protrusions 51 located at the cable insertion cavity 7 at the cable port position. When the cable is inserted, the protrusions 51 cooperate with the grooves on the cable to lock it and prevent the cable from coming loose.

[0023] The working process of this utility model is as follows: When using the 0.2Pitch 0.95H front-insertion, front-flip external snap-fit ​​FPC connector, the connector body 1, plastic shell 4, and cover 2 are injection molded from LCP plastic material. The cover 2 has protrusions 9 on both sides and 0.1mm deep anti-slip textures, with a pivot 10 reserved in the middle to mate with the terminal 3. The connector body 1 has a pin groove 6 (with 0.02-0.05mm raised ribs on the inner wall), a sliding groove, and a cable insertion cavity 7. Two protrusions 51 are pre-made at the cable insertion port of the cable insertion cavity 7. The terminal 3 is made of gold-plated phosphor bronze and is stamped, including an upper arm, a lower spring arm, and a transition arc structure, with contact points 31 processed at the end. The plastic shell 4 has slots 8 on both sides to mate with the protrusions 9. During assembly, terminal 3 is inserted into the pin groove 6 of connector body 1, and the raised rib fits tightly against the side of terminal 3 to achieve fixation; cover 2 is assembled to connector body 1 through a sliding groove, and the rotating shaft 10 cooperates with the upper arm of terminal 3; plastic shell 4 is assembled with connector body 1 to ensure that the protrusion 9 of cover 2 can be inserted into the slot 8 of plastic shell 4 to form a lock; When the cover is open (GAP 0.30mm), insert the ribbon cable into the cavity 7. The ribbon cable groove and the boss 51 cooperate to achieve initial locking. Rotate the cover 2 to the closed position (GAP 0.15mm). The protrusion 9 engages with the slot 8 to complete the locking. The bottom of the cover 2 presses down on the ribbon cable. The upper arm of the terminal 3 deforms to generate downward pressure, so that the ribbon cable and the lower spring arm conduct through the contact point 31. Rotate the cover 2 in the opposite direction to the open position. The protrusion 9 will disengage from the slot 8. The ribbon cable can be pulled out after the limit of the protrusion 51 is released. If parts need to be replaced, separate the plastic shell 4 from the connector body 1, remove the cover 2 and the terminal 3 for replacement, and repeat the assembly process.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
