Description

Technical Field

[0001] This utility model relates to the field of camera module technology, and more specifically, to a camera module with an FPC. Background Technology

[0002] In the design and manufacturing process of camera modules, FPC (flexible printed circuit board) serves as an important bridge connecting camera components and the motherboard. Its performance and reliability directly affect the functionality and quality assurance of the entire camera module. There are various FPC interface options, including connectors, plug-in gold fingers, and soldered gold fingers. Among them, soldered gold fingers are widely used in high-end camera modules due to their advantages such as stable connection and high signal transmission efficiency.

[0003] However, soldered gold fingers also have a significant drawback: the gold finger portion is directly exposed, mainly because the tip of the gold finger is flush with the FPC insertion end (i.e., as shown in the image). Figure 4 As shown, Figure 4 (Point A is labeled FPC, and point B is labeled gold fingers). During the operation of the camera module, the tip of the gold fingers is prone to collision with external objects, causing deformation and affecting subsequent connection with the connector. Therefore, we have improved this by proposing a camera module with an FPC. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is that the front end of the gold finger is flush with the FPC insertion end, and the front end is prone to collision and deformation with external objects.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A camera module with an FPC (Flexible Printed Circuit) includes: an FPC body and FPC gold fingers disposed on the FPC body. A protective edging is provided on the front side of the insertion end of the FPC body, and the protective edging is used to protect the tip of the FPC gold fingers. This application, by providing a protective edging at the front end of the insertion end of the FPC body, ensures that the tip of the FPC gold fingers is protected by the edging. During operation, this reduces the likelihood of deformation of the tip of the protective edging due to impacts, thus improving the integrity of the protective edging structure.

[0007] As an improvement of this utility model, the inner side of the protective edging is flush with the FPC gold fingers to ensure a smooth insertion process.

[0008] As an improvement of this utility model, the protective edging is connected to the FPC body by integral molding or adhesive bonding to ensure a firm bond between the protective edging and the FPC body, reducing the possibility of detachment or displacement during operation or transportation.

[0009] As an improvement of this utility model, the front side of the protective edge is on the same horizontal plane as the front side of the FPC gold finger, reducing the impact of the protective edge on the electrical connection between the FPC gold finger and the connector after insertion.

[0010] As an improvement of this utility model, the FPC body and the protective edging are both provided with arc-shaped chamfers; the arc-shaped chamfers increase the damage resistance of the FPC body and the protective edging edges.

[0011] As an improvement of this utility model, a camera module body is provided on the front side of the FPC body away from the FPC gold fingers.

[0012] As an improvement of this utility model, a reinforcement member is provided on the back side of the FPC body away from the FPC gold finger. The reinforcement member is used to reinforce the corresponding positions of the FPC body and the camera module body.

[0013] As an improvement of this utility model, the reinforcing component is a reinforcing plate, which is glued to the back of the FPC body. The glue bonding method is simple to operate, requires no complicated processes and equipment, reduces production costs, and the reinforcing plate can enhance the rigidity of the FPC body, reduce its deformation under stress, and protect the camera module body and internal circuitry.

[0014] As an improvement of this utility model, the shape of the reinforcing plate is adapted to the shape of the area corresponding to the camera module body on the back of the FPC body.

[0015] As an improvement of this utility model, a protective layer is provided on the outer side of the protective edging.

[0016] Compared with the prior art, the embodiments of this utility model have the following main advantages:

[0017] To address the issue in existing technologies where the front end of the gold finger is flush with the FPC insertion end, making it susceptible to deformation from collisions with external objects, this application provides a protective edging at the front end of the FPC insertion end. This protective edging protects the front end of the FPC gold finger, reducing the likelihood of deformation due to impacts during operation and improving the integrity of the protective edging structure. As a critical electrical connection component, the FPC gold finger is subject to insertion and removal operations with the connector and is highly susceptible to external impacts. The protective edging protects the front end of the FPC gold finger, absorbing and dispersing the impact force when it strikes, reducing the concentration of impact on the FPC gold finger and effectively lowering the risk of deformation.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The reference herein to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] As described in the background section, soldered gold fingers also have a significant drawback: the gold finger portion is directly exposed, primarily because the tip of the gold finger is flush with the FPC insertion end (i.e., as shown in the background section). Figure 4 As shown, Figure 4 (Point A is marked as FPC, and point B is marked as gold finger). During the operation of the camera module, the front end of the gold finger is prone to collision with external objects, which can cause the gold finger to deform and affect the subsequent insertion with the connector.

[0026] To solve this technical problem, this utility model provides a camera module with an FPC.

[0027] For details, please refer to Figures 1-3 The camera module with FPC specifically includes:

[0028] The FPC body 1 and the FPC gold finger 101 disposed on the FPC body 1 are provided with a protective edge 2 on the front side of the insertion end of the FPC body 1, and the protective edge 2 is used to protect the front end of the FPC gold finger 101.

[0029] The camera module with FPC provided by this utility model provides a protective edge 2 at the front end of the insertion end of the FPC body 1. This allows the front end of the FPC gold finger 101 to be protected by the protective edge 2. During operation, this reduces the possibility of deformation of the front end of the protective edge 2 due to impacts, and improves the structural integrity of the protective edge 2. As a key electrical connection component, the FPC gold finger 101 needs to be plugged and unplugged with the connector and is extremely susceptible to external impacts. The protective edge 2 can protect the front end of the FPC gold finger 101. When an impact force is received, the protective edge 2 will first bear and disperse these external forces, reducing the impact force concentrated on the FPC gold finger 101, thereby effectively reducing its deformation risk.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] Embodiment 1 of the camera module with FPC of this utility model

[0034] Please refer to Figures 1-3The camera module with FPC of this utility model includes: FPC body 1 and FPC gold finger 101 disposed on FPC body 1. A protective edge 2 is provided on the front side of the insertion end of FPC body 1, and the protective edge 2 is used to protect the front end of FPC gold finger 101.

[0035] This application provides a protective edge 2 at the front end of the insertion end of the FPC body 1, so that the front end of the FPC gold finger 101 can be protected by the protective edge 2. During operation, it can reduce the deformation of the front end of the protective edge 2 due to bumps and impacts, and improve the integrity of the protective edge 2 structure. As a key electrical connection component, the FPC gold finger 101 needs to be plugged and unplugged with the connector and is extremely susceptible to external impact. The protective edge 2 can protect the front end of the FPC gold finger 101. When it is hit by an impact, the protective edge 2 will first bear and disperse these external forces, reducing the impact force concentrated on the FPC gold finger 101, thereby effectively reducing its deformation risk.

[0036] It should be noted that due to the limitations of the application scenarios of FPC gold fingers 101, they must be exposed. The protective edge 2 is only for front-end protection, reducing the possibility of FPC gold fingers 101 being deformed due to bumps and knocks. This does not affect its normal plugging and unplugging and electrical connection functions, and can effectively protect the vulnerable parts.

[0037] Furthermore, such as Figure 1 As shown, the inner side of the protective edge 2 is flush with the FPC gold finger 101 to ensure a smooth insertion process.

[0038] Furthermore, the protective edge 2 is connected to the FPC body 1 by integral molding or adhesive bonding, ensuring a firm bond between the protective edge 2 and the FPC body 1 and reducing the possibility of detachment or displacement during operation or transportation. Because of the integral molding or firm adhesive bonding, the protective edge 2 and the FPC body 1 form a stable whole, and will not easily separate even when subjected to external forces such as vibration or pulling, providing reliable protection for the FPC gold finger 101.

[0039] Furthermore, the front of the protective edge 2 is on the same horizontal plane as the front of the FPC gold finger 101, reducing the impact of the protective edge 2 on the electrical connection between the FPC gold finger 101 and the connector after they are plugged in.

[0040] Furthermore, such as Figure 1 As shown, both the FPC body 1 and the protective edging 2 are provided with arc-shaped chamfers 5. The arc-shaped chamfers 5 increase the damage resistance of the edges of the FPC body 1 and the protective edging 2. Because the arc-shaped chamfers 5 change the direction of the external force, the stress is evenly distributed, reducing the occurrence of cracks and damage due to excessive local stress on the edges, and improving the camera module's resistance to mechanical damage.

[0041] Embodiment 2 of the present invention: a camera module with an FPC.

[0042] The camera module with FPC of this utility model further includes, for example... Figures 1-2 As shown, a camera module body 3 is provided on the front side of the FPC body 1 away from the FPC gold finger 101. By placing the camera module body 3 on the FPC body 1, the flexible and bendable characteristics of the FPC can be used to flexibly arrange the layout, adapt to the space constraints of different devices, and improve the versatility and applicability of the product.

[0043] Furthermore, a reinforcement member is provided on the back side of the FPC body 1 away from the FPC gold finger 101. The reinforcement member is used to reinforce the corresponding positions of the FPC body 1 and the camera module body 3; to enhance the strength of the connection between the FPC body 1 and the camera module body 3, and to reduce the separation of the two or damage to the FPC body 1 caused by external forces.

[0044] Furthermore, such as Figure 2 As shown, the reinforcing component is a reinforcing plate 4, which is glued to the back of the FPC body 1. The glue bonding method is simple to operate, requires no complicated processes and equipment, and reduces production costs. The reinforcing plate 4 can enhance the rigidity of the FPC body 1, reduce its deformation under stress, and protect the camera module body 3 and internal circuits.

[0045] Furthermore, such as Figure 2 As shown, the shape of the reinforcing plate 4 is adapted to the shape of the area corresponding to the camera module body 3 on the back of the FPC body 1; the adapted shape ensures that the reinforcing plate 4 fits the FPC body 1, and under the action of external force, the force can be evenly transmitted to the entire area, reducing excessive local stress and improving the overall reliability of the camera module.

[0046] Embodiment 3 of the present invention: a camera module with an FPC

[0047] Furthermore, the camera module with FPC of this utility model has a protective layer on the outer side of the protective edge 2. The protective layer is used to enhance the wear resistance of the protective edge 2 during long-term use; extend the service life of the protective edge 2; and ensure its continuous and effective protection of the FPC gold fingers 101. During frequent insertion and removal or long-term use of the camera module, the protective layer can resist friction and wear, prevent the surface of the protective edge 2 from being scratched or worn thin, and always maintain good protective performance.

[0048] The protective layer can be made of polytetrafluoroethylene (PTFE). PTFE has an extremely low coefficient of friction, which can significantly reduce friction during insertion and extraction and reduce wear. At the same time, PTFE is chemically stable, resistant to strong acids, strong alkalis and various organic solvents, and can adapt to harsh operating environments. PTFE can be applied to the protective edging 2 by coating, and the thickness of the protective layer is 0.5-1 mm.
