Description

Technical Field

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

[0002] In the camera module industry, the interface design of the plug type is a key link to ensure stable electrical signal transmission between the module and the device. Currently, the ZIF (Zero Insertion Force) interface design widely used in the industry mainly relies on FPC (Flexible Printed Circuit) interface. This design usually includes gold fingers with exposed copper on one side (front) for electrical contact with the connector, and reinforcing material on the other side (back) to enhance the mechanical strength of the FPC. However, existing ZIF interface designs have significant problems during the mating process between the gold fingers and the connector. Because the back of the gold fingers is supported only by reinforcing material, lacking clear positioning and handle designs, it is difficult for employees to accurately control the mating force and angle during actual operation. This often leads to two adverse consequences: first, excessive force or misalignment by the employee results in poor contact between the gold fingers and the connector, thus affecting the stable transmission of electrical signals; second, the gold fingers are subjected to unnecessary mechanical stress during mating and unmating, increasing the risk of damage such as bending, breakage, or wear of the exposed copper layer. Therefore, we propose an improvement to address this issue by developing a camera module. Utility Model Content

[0003] The technical problem to be solved by this utility model embodiment is that the back of the gold finger is only supported by reinforcing material, and there is a lack of obvious positioning and handle design.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A camera module includes: a camera assembly, the camera assembly including an FPC body, an FPC reinforcing plate connected to the FPC body, a positioning reinforcing plate connected to the side of the FPC reinforcing plate away from the FPC body, the area of ​​the positioning reinforcing plate being smaller than the width of the FPC reinforcing plate, and a stepped structure formed between the bottom of the positioning reinforcing plate and the FPC reinforcing plate, the stepped structure being used for positioning during insertion.

[0005] As an improvement of this utility model, the side of the FPC body away from the FPC reinforcing plate is provided with FPC gold fingers. Specifically, the stepped structure is used for positioning when the FPC gold fingers and the connector are inserted, so as to confirm the insertion depth of the FPC gold fingers.

[0006] As an improvement of this utility model, the end of the FPC body away from the FPC gold fingers is connected to a PCB board, and the PCB board is provided with a camera module body.

[0007] As an improvement of this utility model, a reinforcement is provided at the junction of the camera module body, the PCB board and the FPC body.

[0008] As an improvement of this utility model, the reinforcing component is a reinforcing adhesive, which is connected at the junction of the camera module body, the PCB board and the FPC body.

[0009] As an improvement of this utility model, the outer surface of the positioning reinforcement plate is provided with anti-slip texture.

[0010] As an improvement of this utility model, the anti-slip texture is a cross-grid pattern.

[0011] As an improvement of this utility model, the surface of the FPC gold finger is provided with an anti-oxidation coating, which is a gold plating layer.

[0012] As an improvement of this utility model, a heat-conducting layer is provided on the back of the PCB board, and the heat-conducting layer is made of an insulating material, namely aluminum nitride ceramic.

[0013] As an improvement of this utility model, the thermally conductive layer is bonded to the back of the PCB board by a thermally conductive adhesive, wherein the thermally conductive adhesive is an organosilicon thermally conductive adhesive.

[0014] Compared with the prior art, the embodiments of this utility model have the following main advantages: To address the issue that existing technologies rely solely on reinforcing materials for support on the back of the gold fingers, lacking clear positioning and handle designs, this application adds a positioning reinforcing plate to the existing FPC reinforcing plate. The newly added positioning reinforcing plate forms a stepped structure with the original FPC reinforcing plate, facilitating insertion and removal by the user, reducing operational difficulty, and improving work efficiency.

[0017] 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.

[0018] As described in the background section, existing ZIF interface designs have significant problems in the mating process between the gold fingers and the connector. Because the back of the gold fingers is only supported by reinforcing material and lacks obvious positioning and handle design, it is difficult for employees to accurately control the mating force and angle during actual operation. This often leads to two adverse consequences: First, employees use excessive force or insert the gold fingers at an angle, resulting in poor contact between the gold fingers and the connector, which in turn affects the stable transmission of electrical signals; second, the gold fingers are subjected to unnecessary mechanical stress during the mating and unmating process, increasing the risk of damage to the gold fingers, such as bending, breakage, or wear of the exposed copper layer.

[0019] To solve this technical problem, this utility model provides a camera module.

[0020] For details, please refer to Figures 1-4 The camera module specifically includes: The camera assembly 1 includes an FPC body 101, an FPC reinforcing plate 102 connected to the FPC body 101, and a positioning reinforcing plate 2 connected to the side of the FPC reinforcing plate 102 away from the FPC body 101. The area of ​​the positioning reinforcing plate 2 is smaller than the width of the FPC reinforcing plate 102, and a step structure is formed between the bottom of the positioning reinforcing plate 2 and the FPC reinforcing plate 102. The step structure is used for positioning during insertion. The positioning reinforcing plate 2 is connected to the FPC reinforcing plate 102 by welding or bonding.

[0021] The camera module provided by this utility model adds a positioning reinforcement plate 2 to the original FPC reinforcement plate 102. The newly added positioning reinforcement plate 2 and the original FPC reinforcement plate 102 form a stepped structure, which facilitates the user's insertion and removal, reduces the difficulty of operation, and improves work efficiency. The lower edge of the positioning reinforcement plate 2 protrudes and can form a locking position with the connector, which plays a role in assisting the positioning of the FPC gold finger 103 when it is inserted into the connector. This reduces the top damage caused by excessive insertion of the FPC gold finger 103 and also reduces poor contact caused by insufficient insertion.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] Embodiment 1 of the camera module of this utility model Please refer to Figures 1-4 The camera module of this utility model includes: a camera component 1, which includes an FPC body 101, an FPC reinforcing plate 102 connected to the FPC body 101, and a positioning reinforcing plate 2 connected to the side of the FPC reinforcing plate 102 away from the FPC body 101. The area of ​​the positioning reinforcing plate 2 is smaller than the width of the FPC reinforcing plate 102, and a stepped structure is formed between the bottom of the positioning reinforcing plate 2 and the FPC reinforcing plate 102. The stepped structure is used for positioning during insertion. The positioning reinforcing plate 2 is connected to the FPC reinforcing plate 102 by welding or bonding. This application adds a positioning reinforcement plate 2 to the existing FPC reinforcement plate 102. The newly added positioning reinforcement plate 2 forms a stepped structure with the original FPC reinforcement plate 102, which facilitates the user's insertion and removal, reduces the difficulty of operation, and improves work efficiency. The lower edge of the positioning reinforcement plate 2 protrudes and can form a locking position with the connector, which helps to position the FPC gold finger 103 when it is inserted into the connector, reduces the damage to the top caused by excessive insertion of the FPC gold finger 103, and also reduces poor contact caused by insufficient insertion.

[0026] Furthermore, such as Figures 1-2As shown, an FPC gold finger 103 is provided on the side of the FPC body 101 away from the FPC reinforcing plate 102. Specifically, the stepped structure is used for positioning the FPC gold finger 103 and the connector during insertion, so as to confirm the insertion depth of the FPC gold finger 103. That is, the insertion depth of the FPC gold finger 103 is controlled by the stepped structure to ensure that the effective contact area between the FPC gold finger 103 and the internal contacts of the connector meets the design standard, thereby improving the stability and reliability of signal transmission.

[0027] Furthermore, such as Figure 1 As shown, the end of the FPC body 101 away from the FPC gold finger 103 is connected to the PCB board 104, and the PCB board 104 is provided with the camera module body 105. The FPC body 101 realizes the flexible connection between the camera module body 105 and the external circuit, which not only ensures the stability of the signal transmission path, but also provides the flexibility of structural design, making it suitable for miniaturized, high-density electronic device integration.

[0028] Furthermore, such as Figure 1 As shown, a reinforcing member is provided at the junction of the camera module body 105, PCB board 104, and FPC body 101. The reinforcing member is a reinforcing adhesive 106, which is connected at the junction of the camera module body 105, PCB board 104, and FPC body 101. The reinforcing adhesive 106 is epoxy resin adhesive, which is used to reinforce the junction of the camera module body 105, PCB board 104, and FPC body 101, effectively resisting stress concentration under external forces such as vibration and impact, and improving the overall reliability and service life of the camera module.

[0029] Embodiment 2 of the camera module of this utility model Furthermore, the outer surface of the positioning reinforcement plate 2 of this utility model is provided with anti-slip texture to increase the friction between the outer surface of the positioning reinforcement plate 2 and the fingers, making it easier to insert and remove the camera module.

[0030] Furthermore, the anti-slip texture is a cross-grid pattern. The cross-grid pattern increases the roughness of the outer surface of the positioning reinforcement plate 2, thereby increasing the coefficient of friction between the finger and the device. When the user inserts or removes the camera module, the greater friction provides a more stable grip and reduces finger slippage, making it especially suitable for scenarios that require frequent operation or one-handed operation.

[0031] Embodiment 3 of the camera module of this utility model Furthermore, the surface of the FPC gold finger 103 of this utility model is provided with an anti-oxidation coating, which is a gold-plated layer, to improve the conductivity and service life of the FPC gold finger 103. The gold-plated layer has extremely high chemical stability and conductivity, reducing oxidation and corrosion on the surface of the FPC gold finger 103, thereby extending the electrical performance of the camera module.

[0032] Furthermore, such as Figure 5 As shown, a heat-conducting layer 107 is provided on the back of the PCB board 104. The heat-conducting layer 107 is made of insulating material, which is aluminum nitride ceramic. Its thermal conductivity is not less than 170W / (m·K). It can effectively conduct heat away from the PCB board 104 while ensuring insulation performance, thereby reducing the operating temperature of the PCB board 104. The position of the heat-conducting layer 107 mainly corresponds to the position of the camera module body 105.

[0033] Furthermore, the thermally conductive layer 107 is bonded to the back of the PCB board 104 with thermally conductive adhesive, which is an organic silicone thermally conductive adhesive.

The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model.
