Description

Technical Field

[0001] This utility model relates to the field of FPC connector technology, specifically to a 0.8Pitch1.2H front-insertion, front-flipping external snap-fit ​​FPC connector, which is suitable for signal transmission scenarios in consumer electronics, automotive electronics and other fields. Background Technology

[0002] Existing front-mounted, front-opening FPC connectors have the following drawbacks:

[0003] The cap assembly relies on a hard interference method, and the two end posts are prone to breakage, especially in products with a small number of pins;

[0004] There is a conflict between the cap's locking force and the ribbon cable's holding force, which can easily lead to poor conductivity or cap damage in products with a large number of pins.

[0005] Over-reliance on material properties and unstable GAP values ​​when the cable is unplugged or the cover is open make it difficult to insert the ribbon cable.

[0006] The cover is prone to loosening, causing misalignment during SMT placement;

[0007] The ribbon cable is not securely fixed and is prone to coming loose;

[0008] The product is too tall (1.6mm in standard), which cannot meet the requirements for a thinner and lighter device.

[0009] Therefore, it is necessary to design a 0.8Pitch1.2H front-insertion, front-flipping external snap-fit ​​FPC connector to solve the problems mentioned above. Utility Model Content

[0010] This utility model aims to solve the problems of existing front-mounted, front-flip FPC connectors, such as easy breakage of the cover assembly, contradiction between the fastening force and the cable holding force, SMT misalignment caused by loose cover, easy detachment of the cable, unclear markings, and inability to adapt the size to thin and light devices. It provides a 0.8Pitch1.2H front-mounted, front-flip external snap-fit ​​FPC connector, which improves assembly stability, connection reliability and ease of use through structural optimization and marking design.

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] A 0.8Pitch1.2H front-mounted, front-flipping external snap-fit ​​FPC connector mainly consists of a connector body, plastic cover, terminals, plastic shell, ribbon cable locking structure, LOGO label, and contact number.

[0013] Furthermore, the connector body is 1.2mm high and made of polylactic acid biodegradable material, which is environmentally friendly and structurally stable. It has a pin groove to accommodate the terminal and a cable port for cable insertion. The inner wall of the pin groove has 0.02-0.05mm 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.

[0014] Furthermore, the terminal spacing is 0.8mm, and it is made of gold-plated phosphor bronze. It includes an upper arm and a lower spring arm. The upper arm cooperates with the hinge of the plastic cover. When it is fastened, it generates a downward force through deformation, so that the ribbon cable contacts and conducts through the lower spring arm. There is a transition arc structure between the upper arm and the lower spring arm, which can disperse stress, prevent the terminal from breaking due to repeated deformation, and improve durability.

[0015] Furthermore, the plastic cover has protrusions on both sides, and the connector body has corresponding fixing plates on both sides. The fixing plates have slots, and the protrusions and slots cooperate to form a locking structure to prevent the plastic cover from loosening. The surface of the protrusions has 0.1mm deep anti-slip textures, which create friction with the inner wall of the slots to further enhance the stability of the lock.

[0016] Furthermore, the plastic 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. The difference in size allows the bottom of the plastic cover to press down on the ribbon cable and make contact with the front end of the terminal.

[0017] Furthermore, the ribbon cable locking structure includes two protrusions located at the ribbon cable port. When the ribbon cable is inserted, the protrusions engage with the grooves on the ribbon cable to lock it in place and prevent the ribbon cable from coming loose.

[0018] Furthermore, the logo label is placed on the outer surface of the plastic cover for easy product traceability and brand identification; the contact number corresponding to the terminal position is placed on the plastic cover to clearly distinguish the signal channels of each terminal and reduce assembly errors.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This utility model, through the design of a 0.8Pitch 1.2H front-insertion, front-flip external snap-fit ​​FPC connector, achieves the following effects: 1. The locking structure of the convex bulge and slot, along with the anti-slip texture design, solves the SMT placement misalignment problem caused by loose plastic caps; the raised ribs on the inner wall of the pin slot enhance the terminal fixation effect, ensuring stable contact impedance (≤40mΩ); 2. The transition arc structure of the terminal disperses the stress during snap-fit, improving durability (≥60 cycles); the boss of the ribbon cable locking structure cooperates with the ribbon cable groove, enabling the ribbon cable pull-out force to reach over 30gf / pin, effectively preventing loosening; 3. The 1.2mm low height design is 25% lower than conventional products (1.6mm), meeting the demand for thinner and lighter electronic devices; the use of polylactic acid biodegradable materials conforms to environmental protection trends; 4. The design of the LOGO label and contact number facilitates product identification and signal correspondence, reducing misoperation during assembly, and is especially suitable for multi-pin scenarios.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are provided. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0033] Example 1

[0034] This embodiment provides a 0.8Pitch1.2H front-mounted, front-flip external snap-fit ​​FPC connector, the structure of which includes connector body 1, plastic cover 2, terminal 3, plastic shell 4, ribbon cable locking structure 5, LOGO label 12 and contact number 13.

[0035] Example 2

[0036] Based on Example 1, this embodiment further defines the core parameters of the connector: the height of the connector body 1 is 1.2mm and the spacing of the terminals 3 is 0.8mm. This size design enables it to adapt to electronic device scenarios with stringent space requirements.

[0037] Example 3

[0038] Based on Embodiment 1, this embodiment further specifies that the connector body 1 has a dedicated pin groove 6 for accommodating the terminal 3 and a ribbon cable port 7 for inserting the ribbon cable. The plastic cover 2, as a key component, has protrusions 8 on both sides, while the connector body 1 has corresponding fixing pieces 9 on both sides. The fixing pieces 9 have slots 10. The protrusions 8 and the slots 10 cooperate to form a stable locking structure, ensuring the stability of the plastic cover 2 in the locked state.

[0039] Example 4

[0040] Based on Embodiment 1, this embodiment further specifies that the plastic cover 2 has a rotating shaft 11 in the middle that cooperates with the terminal 3. By rotating the rotating shaft 11, the cable can be pressed. For easy identification and use, a LOGO label 12 is provided on the outer surface of the plastic cover 2, and the contact number 13 is provided on the plastic cover 2 corresponding to the position of the terminal 3, so that the operator can quickly identify the connection relationship between the terminal and the cable.

[0041] Example 5

[0042] Based on the 0.8Pitch1.2H front-insertion, front-flip external snap-fit ​​FPC connector described in Embodiment 1, this embodiment further defines the ribbon cable locking structure 5. The ribbon cable locking structure 5 includes two protrusions 51 located at the ribbon cable port 7. When the ribbon cable is inserted into the ribbon cable port 7, these two protrusions 51 can precisely cooperate with the grooves on the ribbon cable, thereby locking the ribbon cable and effectively preventing the ribbon cable from loosening or falling off during use, ensuring the reliability of the connection.

[0043] Example 6

[0044] Regarding the 0.8Pitch1.2H front-mounted, front-flip external FPC connector in Embodiment 1, this embodiment focuses on the parameters of the closed / closed state of the plastic cover 2. The gap (GAP) of the plastic cover 2 in the open state is 0.30mm, and the GAP in the closed state is 0.15mm. The ingenious aspect of this size difference design is that when the plastic cover 2 switches from the open state to the closed state, the bottom of the plastic cover 2 generates pressure through the size change, pressing the ribbon cable and making it tightly contact the contact point 31 at the front end of the terminal 3, thereby achieving conductivity and ensuring stable transmission of current or signal.

[0045] Example 7

[0046] Based on Embodiment 1, this embodiment provides a detailed description of the structure of terminal 3. Terminal 3 includes an upper arm and a lower spring arm. The upper arm engages with the rotating shaft 11. When the plastic cover 2 is fastened, the upper arm deforms and generates a downward force. This force causes the ribbon cable to make tight contact with the lower spring arm, thereby achieving conductivity. Furthermore, a transition arc structure is provided between the upper arm and the lower spring arm. This structure effectively disperses stress, preventing terminal 3 from breaking during repeated deformation and extending the terminal's service life.

[0047] Example 8

[0048] For the 0.8Pitch1.2H front-mounted, front-flipping external FPC connector in Embodiment 1, this embodiment optimizes the design of the Pin groove 6 of the connector body 1. The inner wall of the Pin groove 6 of the connector body 1 is provided with raised ribs of 0.02-0.05mm. When the terminal 3 is installed in the Pin groove 6, these raised ribs can fit tightly against the side of the terminal 3. On the one hand, this improves the installation stability of the terminal 3 in the Pin groove 6, preventing the terminal 3 from shaking; on the other hand, it enhances the contact tightness between the two, helping to reduce contact resistance and ensuring the quality of signal transmission.

[0049] Example 9

[0050] Based on the 0.8Pitch1.2H front-insertion, front-flip external snap-fit ​​FPC connector of Embodiment 1, this embodiment improves the convex 8 of the plastic cover 2. The surface of the convex 8 is provided with anti-slip textures with a depth of 0.1mm. When the convex 8 and the slot 10 on the fixing piece 9 cooperate to form a locking structure, the anti-slip textures can generate a large friction force with the inner wall of the slot 10, making the locking structure more secure and preventing the plastic cover 2 from being accidentally opened under vibration, impact and other environments, thus ensuring the normal operation of the connector.

[0051] Example 10

[0052] Based on Example 1, this example specifies the materials used for the connector. The connector body 1 is made of polylactic acid (PLA), a biodegradable material that has good biodegradability, meets environmental protection requirements, and reduces environmental pollution after product disposal. The terminal 3 is made of gold-plated phosphor bronze. The gold plating improves the conductivity and oxidation resistance of the terminal, while the phosphor bronze ensures good elasticity and strength, extending the connector's service life.

[0053] The working process of this utility model is as follows: When using the 0.8Pitch1.2H front-mounted, front-flip external snap-fit ​​FPC connector, the connector is in the open state. At this time, the gap of the plastic cover 2 is 0.30mm, and the protrusion 8 is separated from the slot 10 on the fixing piece 9. The terminal 3 is stably installed inside the connector body 1 through the pin groove 6. The raised ribs on the inner wall of the pin groove 6 are tightly fitted with the side of the terminal 3 to ensure that the terminal 3 is fixed in position. The ribbon cable is aligned with the ribbon cable port 7 and inserted. The two protrusions 51 in the ribbon cable locking structure 5 located in the ribbon cable port 7 are precisely engaged with the grooves on the ribbon cable to achieve initial locking of the ribbon cable and prevent displacement during the insertion of the ribbon cable. The rotating shaft 11 in the middle of the plastic cover 2 is rotated so that the plastic cover 2 rotates towards the connector body 1. During this process, the protrusions 8 on both sides of the plastic cover 2 gradually approach and embed into the slot 10 of the fixing piece 9 to form a locking structure. As the plastic cover 2 rotates, its gap gradually decreases from 0.30mm to 0.15mm. This dimensional difference creates pressure on the ribbon cable from the bottom of the plastic cover 2. When the plastic cover 2 is closed, the upper arm of the terminal 3 deforms in conjunction with the rotating shaft 11, generating a downward force that forces the ribbon cable into close contact with the lower spring arm of the terminal 3. Simultaneously, the ribbon cable is pressed against the contact point 31 at the front end of the terminal 3, ensuring stable current or signal conduction. The transition arc structure between the upper arm and the lower spring arm of the terminal 3 disperses stress, ensuring the structural stability of the terminal 3 during deformation. The connector model can be identified by the LOGO label 12 on the outer surface of the plastic cover 2, and the contact number 13 corresponding to the terminal 3 position facilitates operators in verifying the connection relationship between the ribbon cable and the terminal 3, ensuring accurate connection.

[0054] 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.
