Technical Field

[0001] This application relates to the field of electronic device technology, and more specifically, to a connection component, a camera module, and an electronic device. Background Technology

[0002] To enhance the competitiveness of terminal products, specifications and new features are constantly being added, making stable electrical connections between different components a challenge. Since terminal products contain multiple antennas, unstable electrical connections between different components can easily affect the antenna's radio frequency performance, thereby impacting the performance of the terminal product. Utility Model Content

[0003] This application provides a connection component, a camera module, and an electronic device, which enables the connection component to have both structural stability and electrical connection stability.

[0004] In a first aspect, a connecting assembly is provided, including a first connector and a second connector, wherein the first connector and the second connector are metal parts, and an insulating layer is provided on the surface of the first connector and the second connector; the first connector includes a first protrusion and a second protrusion, the first protrusion and the second protrusion being disposed on the side of the first connector near the second connector, the first protrusion having a larger dimension in a first direction than the second protrusion having a dimension in the first direction, the first direction being perpendicular to the circumferential direction of the first connector; the second connector includes a first recess and a second recess, the first recess and the second recess being disposed on the side of the second connector near the first connector, the first recess having a larger dimension in the first direction than or equal to the second recess having a dimension in the first direction, at least a portion of the first protrusion being accommodated in the first recess, at least a portion of the second protrusion being accommodated in the second recess, and the first protrusion and the first recess having a gap in the first direction.

[0005] In the embodiments provided in this application, during the assembly of the first connector and the second connector, the first protrusion and the second connector come into contact with each other and generate friction. The insulating layer on the surface of the first protrusion is prone to wear, while the second protrusion is smaller in size in the first direction than the first protrusion, and there is no contact between the second protrusion and the second connector. When the assembly is complete, the first protrusion is accommodated in the first recess, and there is a gap between the two, which allows the first protrusion and the first recess to be mutually insulated. The surface of the second protrusion is not worn and it can also be mutually insulated with the second recess, thereby enabling the first connector and the second connector to have stable electrical connection performance, that is, enabling the first connector and the second connector to be stably insulated from each other. Furthermore, through the mutual cooperation of the protrusion and the recess, the connecting assembly can have high structural stability and reliability.

[0006] In some examples, the first connector further includes a first body portion, to which a first protrusion and a second protrusion are connected, and the first protrusion and the second protrusion are disposed on the side of the first body portion near the second connector.

[0007] Similarly, the second connector also includes a second body portion, with the first and second recesses located on the side of the second body portion near the first connector. During the assembly of the first and second connectors, the first protrusion comes into contact with the second body portion.

[0008] In conjunction with the first aspect, in some implementations of the first aspect, the first protrusion is connected to the second protrusion, and the first recess is connected to the second recess.

[0009] In the embodiments provided in this application, the first protrusion is connected to the second protrusion, which can improve the structural stability of the first protrusion and the second protrusion and prevent deformation during assembly; the first recess is connected to the second recess, so that the first protrusion and the second protrusion can be respectively accommodated in the first recess and the second recess.

[0010] In conjunction with the first aspect, in some implementations of the first aspect, the dimensional difference between the first protrusion and the second protrusion in the first direction is greater than or equal to 0.1 mm.

[0011] In the embodiments provided in this application, the size difference between the first protrusion and the second protrusion in the first direction is greater than or equal to 0.1 mm, which can further improve the insulation effect between the first connector and the second connector.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, the first connector further includes a third protrusion disposed on the side of the second protrusion away from the first protrusion, the third protrusion having a dimension in the first direction greater than the dimension of the second protrusion in the first direction; the second connector further includes a third recess disposed on the side of the second recess away from the first recess, the third recess having a dimension in the first direction greater than or equal to the dimension of the second recess in the first direction, the third protrusion being accommodated in the third recess, and the third protrusion and the third recess having a gap in the first direction.

[0013] In the embodiments provided in this application, the first connector further includes the third protrusion. During the assembly of the connector assembly, the third protrusion and the first protrusion can jointly protect the second protrusion, further enhancing the protective effect on the second protrusion, preventing wear on the second protrusion during assembly, and improving the insulation effect between the first connector and the second connector. Furthermore, the third protrusion and the first protrusion, respectively disposed on the second protrusion to protect it, can also improve the structural stability of the first, second, and third protrusions, preventing structural deformation during assembly. In addition, when the third protrusion is accommodated in the third recess, a gap exists between the third protrusion and the third recess, enabling mutual insulation between the third protrusion and the third recess.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, the third protrusion is connected to the second protrusion, and the third recess is connected to the second recess.

[0015] In the embodiments provided in this application, the third protrusion is connected to the second protrusion, which can further improve the structural stability of the first protrusion, the second protrusion and the third protrusion and prevent deformation during assembly; the third recess is connected to the second recess, which allows the third protrusion to be accommodated in the third recess.

[0016] In conjunction with the first aspect, in some implementations of the first aspect, the dimensional difference between the third protrusion and the second protrusion in the first direction is greater than or equal to 0.1 mm.

[0017] In the embodiments provided in this application, the dimensional difference between the third protrusion and the second protrusion in the first direction is greater than or equal to 0.1 mm, which can further improve the insulation effect between the first connector and the second connector.

[0018] In conjunction with the first aspect, in some implementations of the first aspect, the dimension of the third protrusion in the first direction is the same as the dimension of the first protrusion in the first direction.

[0019] In the embodiments provided in this application, the third protrusion has the same dimension in the first direction as the first protrusion in the first direction. During the assembly of the connecting component, both the third protrusion and the first protrusion are in contact with the second connector, which makes the force on the first connector more balanced and alleviates the deformation problem of the first protrusion, the second protrusion and the third protrusion during the assembly process. Furthermore, the fact that the third protrusion has the same dimension in the first direction as the first protrusion in the first direction can help simplify the processing steps of the first connector and the second connector.

[0020] In conjunction with the first aspect, in some implementations of the first aspect, the second protrusion and the second recess are fitted together in the first direction.

[0021] In the embodiments provided in this application, the second protrusion and the second recess are fitted together in the first direction, which makes the structure of the connecting component more stable; in addition, the mutual fitting between the second protrusion and the second recess in the first direction can also facilitate the formation of a gap between the first main body and the second main body, prevent unstable electrical connection between the first main body and the second main body, and further alleviate the problem of unstable electrical connection between the first connector and the second connector.

[0022] In conjunction with the first aspect, in some implementations of the first aspect, the first protrusion includes a first end face, which is the end face of the first protrusion close to the first recess in the first direction, and the shape of the first end face matches the shape of the second connector.

[0023] In the embodiments provided in this application, the shape of the first end face matches the shape of the second connector. During the assembly of the connecting component, the first protrusion and the second connector have a large contact area, which can alleviate the wear problem of the main body surface of the first protrusion and the second connector, and further improve the insulation effect between the first connector and the second connector.

[0024] In conjunction with the first aspect, in some implementations of the first aspect, the dimension of the first end face in the circumferential direction of the first connector is less than or equal to the dimension of the end of the first protrusion away from the first end face in the circumferential direction of the first connector.

[0025] In the embodiments provided in this application, the dimension of the first end face in the circumferential direction of the first connector is less than or equal to the dimension of the end of the first protrusion away from the first end face in the circumferential direction of the first connector, which makes it easy for the first protrusion to enter the first recess and realize the fastening of the first connector and the second connector.

[0026] In conjunction with the first aspect, in some implementations of the first aspect, the third protrusion includes a second end face, which is the end face of the third protrusion close to the third recess in the first direction, and the shape of the second end face matches the shape of the second connector.

[0027] In the embodiments provided in this application, the shape of the second end face matches the shape of the second connector. During the assembly of the connecting component, the third protrusion and the second connector have a large contact area, which can alleviate the wear problem on the surface of the third protrusion and further improve the insulation effect between the first connector and the second connector.

[0028] In conjunction with the first aspect, in some implementations of the first aspect, the dimension of the second end face in the circumferential direction of the first connector is less than or equal to the dimension of the end of the third protrusion away from the second end face in the circumferential direction of the first connector.

[0029] In the embodiments provided in this application, the dimension of the second end face in the circumferential direction of the first connector is less than or equal to the dimension of the end of the third protrusion away from the second end face in the circumferential direction of the first connector, which makes it easy for the third protrusion to enter the third recess and realize the fastening of the first connector and the second connector.

[0031] In the embodiments provided in this application, the materials of the first connector and / or the second connector are the aforementioned materials, which can improve the reliability of the connection assembly.

[0032] In conjunction with the first aspect, in some implementations of the first aspect, the connecting component is applied to a camera module, wherein the dimension of the first recess in the optical axis direction of the camera module is greater than the dimension of the second recess in the optical axis direction.

[0033] In the embodiments provided in this application, the size of the first recess in the optical axis direction is larger than the size of the second recess in the optical axis direction. The second recess can prevent the first protrusion from entering the second recess and make contact with the second recess in the first direction, thereby further improving the insulation effect of the connection component.

[0034] In conjunction with the first aspect, in some implementations of the first aspect, the connecting component is applied to a camera module, and the dimension of the third recess in the optical axis direction of the camera module is greater than or equal to the dimension of the second recess in the optical axis direction.

[0035] In the embodiments provided in this application, the dimension of the third recess in the optical axis direction is larger than that of the second recess in the optical axis direction. The second recess can prevent the third protrusion from entering the second recess and making contact with the second recess in the first direction, thereby further improving the insulation effect of the connection component.

[0036] In conjunction with the first aspect, in some implementations of the first aspect, the first connector and the second connector are ring-shaped structures, and the first connector is arranged around the outside of the second connector.

[0050] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0051] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0052] In the various embodiments of this application, the terms "first," "second," etc., are merely to indicate that multiple objects are different. For example, "first connector" and "second connector" are only to indicate different connectors. They should not have any effect on the connectors themselves or their quantity, and the aforementioned "first," "second," etc., should not impose any limitations on the embodiments of this application.

[0053] The terms “including,” “comprising,” “having,” and variations thereof all mean “including but not limited to,” unless otherwise specifically emphasized.

[0054] As mentioned above, stable electrical connections between different components in terminal products pose a challenge to product structural design. Unstable electrical connections can easily affect antenna performance, thereby impacting the usability of the terminal product, for example, causing remote security exposure (RSE) issues. Stable electrical connections between different components can have two possible scenarios: one is stable conduction between the components, and the other is stable mutual insulation between the components.

[0055] Figure 1 This is a structural diagram of a connecting component, such as... Figure 1 As shown, the connecting assembly may include structural component 101 and structural component 102. Structural component 101 and structural component 102 may each be provided with screw holes, and the positions of the screw holes of structural component 101 and structural component 102 may correspond to each other. The external thread of screw 103 may match the thread shape on the screw hole, so that structural component 101 and structural component 102 can be fixedly connected by screwing.

[0056] The structural components 101, 102 and screw 103 can be metal parts. The connection of screw 103 can realize the conduction between structural component 101 and structural component 102, so that structural component 101 and structural component 102 are stably electrically connected.

[0057] Since the screw 103 has a certain size and occupies a large space, it can easily affect the stacking density of the end product. Furthermore, structural components 101 and 102 need to have a large size to accommodate the screw 103. To prevent the screw 103 from being exposed and affecting the aesthetics of the product, structural component 101 also needs to cover the screw 103, resulting in a large size for structural component 101 and affecting the competitiveness of the end product.

[0058] This application provides a connection component, a camera module, and an electronic device, such that the connection component has both structural stability and insulation, that is, it enables different structural components in the connection component to be stably insulated from each other.

[0059] Figure 2 This is a schematic diagram of the rear structure of an electronic device provided in an embodiment of this application, as shown below. Figure 2 As shown, the electronic device may include a back cover 210 and a mid-frame 220, with a space between the back cover 210 and the mid-frame 220 to accommodate electronic components. The electronic device may include a camera module 300, which may be a rear-facing camera module. The rear-facing camera module may be disposed on one side of the back cover 210, and the camera module 300 may be connected to the back cover 210.

[0060] The camera module 300 may include a lens assembly (not shown), which may include multiple lenses for guiding light to an image sensor to convert light signals into electrical signals for imaging. At least a portion of the lens assembly may be disposed within the receiving space formed by the mid-frame 220 and the rear cover 210.

[0061] The camera module 300 may further include a protective cover 330 and a connecting assembly. The protective cover 330 can be connected to the connecting assembly, and the protective cover 330 and the connecting assembly can form a receiving space. At least a portion of the lens assembly can be housed within the receiving space formed by the protective cover 330 and the connecting assembly, and the protective cover 330 and the connecting assembly can be used to protect the lens assembly from damage. The protective cover 330 can be a transparent cover, allowing incident light to pass through the protective cover 330 and enter the lens assembly.

[0062] It should be understood that the back cover 210 and the mid-frame 220 can also be a single piece, and this application does not limit this to that. Furthermore, Figure 2 The camera module in the image is a rear camera module, but it can also be a front camera module.

[0063] Figure 3 for Figure 2 The exploded view of the camera module, specifically the exploded view of the connecting components, is shown below. Figure 3 As shown, the connecting assembly may include a first connector 310 and a second connector 320. Both the first connector 310 and the second connector 320 may be metal components, and their surfaces may be provided with an insulating layer. The first connector 310 and the second connector 320 may be a ring-shaped structure as shown in the figure, with the first connector 310 located on the outer side of the second connector 320. The outer side of the second connector 320 may refer to the side of the second connector 320 away from the center of the structure.

[0064] Figure 4 This is a partial structural diagram of the first connector 310, as shown below. Figure 4 As shown, the first connector 310 may include a first protrusion 311 and a second protrusion 312. The first protrusion 311 and the second protrusion 312 may be disposed on the side of the first connector 310 near the second connector 320, and the dimension of the first protrusion 311 in a first direction is larger than the dimension of the second protrusion 312 in the first direction, which is perpendicular to the circumferential direction of the first connector 310. That is, in the first direction, the first protrusion 311 protrudes more than the second protrusion 312.

[0065] The first connector 310 may further include a first main body portion 314, the first protrusion 311 and the second protrusion 312 may be connected to the first main body portion 314, and the first protrusion 311 and the second protrusion 312 may be disposed on the side of the first main body portion 314 near the second connector 320.

[0066] for Figure 4 The first connector 310 shown can have a first main body 314 that can be a ring structure. The dimension of the first protrusion 311 in the first direction is the dimension of the first protrusion 311 from the end away from the first main body 314 to the surface of the ring structure in the first direction. The dimension of the second protrusion 312 in the first direction is similar.

[0067] When the first connector 310 is a circular structure as shown in the figure, the circumferential direction of the first connector 310 is also the circumferential direction, and the first direction is also the radial direction of the first connector 310. The shape of the first connector 310 can be the same as the shape of the second connector 320, and the circumferential direction of the first connector 310 is also the circumferential direction of the second connector 320.

[0068] Accordingly, Figure 5 This is a partial structural diagram of the second connector 320. Figure 6 and Figure 7 This is a partial cross-sectional structural diagram of the second connector 320. (See diagram below.) Figure 5 As shown, the second connector 320 may include a first recess 321 and a second recess 322, which may be disposed on the side of the second connector 320 near the first connector 310. Figure 6 or Figure 7 As shown, the dimension of the first recess 321 in the first direction can be greater than or equal to the dimension of the second recess 322 in the first direction.

[0069] The dimension of the first recess 321 in the first direction is greater than or equal to the dimension of the second recess 322 in the first direction. This can mean that the maximum dimension of the first recess 321 in the first direction is greater than or equal to the maximum dimension of the second recess 322 in the first direction. In other words, in the first direction, the depth of the first recess 321 is the same as the depth of the second recess 322. Figure 6 Alternatively, the depth of the first recess 321 is greater than the depth of the second recess 322. Figure 7 ).

[0070] The second connector 320 may further include a second main body portion 324, wherein the first recess 321 and the second recess 322 may be disposed on the side of the second main body portion 324 near the first connector 310. The first main body portion 314 and the second main body portion 324 may be disposed opposite to each other along a first direction.

[0071] Similar to the first connector 310, the second connector 320 can also be a ring structure. The first recess 321 and the second recess 322 can be obtained by slotting the surface of the second main body 324. The dimension of the first recess 321 in the first direction can refer to the distance in the first direction between the inner end face of the first recess 321 and the outer surface of the ring structure (that is, the outer surface of the complete ring structure in the unslotted state). The dimension of the second recess 322 in the first direction is similar.

[0072] When the connecting assembly is assembled, at least a portion of the first protrusion 311 can be accommodated in the first recess 321, and at least a portion of the second protrusion 312 can be accommodated in the second recess 322. Figure 8 This is a schematic cross-sectional view of the connecting assembly along the first direction at the locations of the first protrusion 311 and the first recess 321, as shown below. Figure 8 As shown, the first protrusion 311 and the first recess 321 have a distance d between their two end faces that are close to each other in the first direction.

[0073] It should be understood that the first connector 310 includes a first protrusion 311 and a second protrusion 312, and the surfaces of the first protrusion 311 and the second protrusion 312 may also be provided with an insulating layer. Similarly, the second connector 320 includes a first recess 321 and a second recess 322, and the surfaces of the first recess 321 and the second recess 322 may also be provided with an insulating layer.

[0074] During the assembly of the first connector 310 and the second connector 320, the first connector 310 can move along... Figure 5 As the object moves in the direction of the arrow, during this movement, because the first protrusion 311 is larger than the second protrusion 312 in the first direction, the first protrusion 311 will come into contact with the second main body 324. During assembly, the first protrusion 311 and the second main body 324 will rub against each other, and the insulating layer on the surface of the first protrusion 311 is prone to wear. When assembled, the first protrusion 311 is accommodated in the first recess 321. Because there is a gap between the first protrusion 311 and the first recess 321 in the first direction, it can prevent unstable electrical connections caused by wear, and ensure that the first protrusion 311 and the first recess 321 are mutually insulated, preventing unstable electrical connections.

[0075] The first protrusion 311 can protect the second protrusion 312. The second protrusion 312 does not contact the second main body 324 during assembly, so that the insulating layer on the surface of the second protrusion 312 is not easily worn. In this way, when the second protrusion 312 is accommodated in the second recess 322, the second protrusion 312 and the second recess 322 can be insulated from each other, preventing unstable electrical connection problems.

[0076] Furthermore, the first connector 310 and the second connector 320 are made of metal, which improves the reliability of the connection assembly. The first protrusion 311 and the second protrusion 312 are respectively accommodated in the first recess 321 and the second recess 322, which makes it difficult for the first connector 310 to separate from the second connector 320, further improving the reliability of the connection assembly.

[0077] When the second protrusion 312 is accommodated within the second recess 322, there may or may not be a gap between the second protrusion 312 and the second recess 322 in the first direction. For example, the structure of the first recess 321 and the second recess 322 is as follows: Figure 6 In the case of the structure shown, the second recess 322 and the second protrusion 312 may have a gap in the first direction, and the structure of the first recess 321 and the second recess 322 is as follows: Figure 7 In the case of the structure shown, the second recess 322 and the second protrusion 312 can contact each other in the first direction, or they can have a gap.

[0078] For example, Figure 9 This is a schematic diagram of the structure when the first connector 310 and the second connector 320 are engaged with each other. Figure 9 This can be a schematic diagram of a cross-sectional structure along the XY plane. For example... Figure 9 As shown, there may be no gap between the second protrusion 312 and the second recess 322 in the first direction, meaning that the second protrusion 312 and the second recess 322 can fit together in the first direction. In this example, the second recess 322 can provide structural support for the second protrusion 312, making the structure of the first connector 310 more stable. Furthermore, since the second recess 322 provides support for the second protrusion 312, the first protrusion 311 is less likely to come into contact with the first recess 321, ensuring stable insulation between the first protrusion 311 and the first recess 321.

[0079] Furthermore, the second recess 322 provides structural support for the second protrusion 312 and also allows a gap to be formed between the first main body portion 314 and the second main body portion 324 in the first direction. During the assembly of this connecting assembly, the first protrusion 311 and the second main body portion 324 come into contact and rub against each other, and the surface of the second main body portion 324 is also prone to wear. The gap formed between the first main body portion 314 and the second main body portion 324 in the first direction prevents unstable electrical connections between them, thereby further alleviating the problem of unstable electrical connections between the first connector 310 and the second connector 320.

[0080] As described above, in some embodiments, the first main body portion 314 and the second main body portion 324 may have a gap in a first direction. During the assembly of the connector, the first protrusion 311 and the second protrusion 312 may come into contact with the second main body portion 324, and the surface of the second main body portion 324 will also wear under friction, resulting in the peeling off of the insulating layer. The gap between the first main body portion 314 and the second main body portion 324 in the first direction enables the first main body portion 314 and the second main body portion 324 to be mutually insulated, preventing unstable electrical connection problems.

[0081] In this application, the first protrusion 311 and the second protrusion 312 can also be referred to as male buckles, and the first recess 321 and the second recess 322 can also be referred to as female buckles.

[0082] For example, the first connector 310 may also be referred to as a decorative element.

[0083] In some embodiments, the difference between the dimension of the first protrusion 311 in the first direction and the dimension of the second protrusion 312 in the first direction may be greater than or equal to 0.1 mm.

[0084] The difference between the size of the first protrusion 311 and the size of the second protrusion 312 in the first direction is greater than or equal to 0.1 mm, which can improve the protective effect of the first protrusion 311 on the second protrusion 312 during the assembly of the connecting assembly.

[0085] Accordingly, when there is no gap between the second recess 322 and the second protrusion 312 in the first direction, the size of the first recess 321 in the first direction can be larger than the size of the second recess 322 in the first direction, and the difference between the size of the first recess 321 and the second recess 322 in the first direction can also be greater than or equal to 0.1 mm.

[0086] For example, the materials of the first connector 310 and the second connector 320 can be any of the following: aluminum, stainless steel or titanium alloy.

[0087] The first connector 310 and the second connector 320 are metal parts, and the materials of the first connector 310 and the second connector 320 are the aforementioned metal materials, which can improve the structural reliability of the first connector 310 and the second connector 320.

[0088] It should be understood that the material of the first connector 310 is a metallic material, which means that the entire structure of the first connector 310 (including the first main body 314, the first protrusion 311, and the second protrusion 312) can be made of a metallic material. The first protrusion 311 and the second protrusion 312 can be an integral structure with the first main body 314, or they can be fixedly connected to each other. For example, the first protrusion 311 and the second protrusion 312 can also be fixedly connected to the first main body 314 by welding, bonding, or other methods. Correspondingly, the material of the first protrusion 311 and the second protrusion 312 can be the same as or different from the material of the first main body 314. Similarly, the material of the first protrusion 311 and the second protrusion 312 can be the same as or different from the material of the second protrusion. Furthermore, the materials of the first connector 310 and the second connector 320 can also be other metallic materials, such as aluminum alloy, etc., and this application does not limit this.

[0089] For example, the material of the insulating layer can be a ceramic material (such as alumina (Al2O3), titanium dioxide (TiO2)), a polymer material (such as polytetrafluoroethylene, epoxy resin), etc.

[0090] For example, when the material of the first connector 310 and / or the second connector 320 is aluminum, the material of the insulating layer can be aluminum oxide, which can be formed on the surface of the aluminum by anodizing. For example, the aluminum component can be immersed in a specific electrolyte, such as sulfuric acid, oxalic acid, or chromic acid solution, as the anode. When a direct current is applied between the aluminum component (anode) and the cathode, electrons flow from the anode to the power source, causing the aluminum atoms on the anode to lose electrons and become aluminum ions (Al). 3+ An oxidation reaction occurs. Furthermore, aluminum ions combine with oxygen ions in the electrolyte to form an aluminum oxide film on the aluminum surface.

[0091] For example, when the material of the first connector 310 and / or the second connector 320 is stainless steel, the insulating layer can be formed on the surface of the first connector 310 and / or the second connector 320 by a diamond-like carbon (DLC) coating process. The DLC process is a technique for forming an amorphous carbon film with diamond-like properties (such as high hardness, low coefficient of friction, wear resistance, and good chemical stability) on the surface of a structural component. For example, the insulating layer can be formed on the surface of the first connector 310 and / or the second connector 320 by physical vapor deposition (PVD).

[0092] For example, when the material of the first connector 310 and / or the second connector 320 is a titanium alloy, the insulating layer can also be formed by PVD.

[0093] It should be understood that the above-described method of forming the insulating layer is merely an example. The insulating layer can also be formed on the surface of the first connector 310 and / or the second connector 320 by other methods, such as spraying, dip coating, sol-gel method, chemical vapor deposition, etc. This application does not limit its application in this regard. The method of forming the insulating layer on the surface of the first connector 310 can be the same as or different from the method of forming the insulating layer on the surface of the second connector 320. The insulating layer material on the surface of the first connector 310 can be the same as or different from the insulating layer material on the surface of the second connector 320.

[0094] See also Figure 4 In some embodiments of the structure shown, the first protrusion 311 may be connected to the second protrusion 312. Accordingly, see below. Figures 5 to 7 As shown in the structure, the first recess 321 can be connected to the second recess 322.

[0095] The connection between the first protrusion 311 and the second protrusion 312 can mean that there is no gap between the first protrusion 311 and the second protrusion 312. For example, the first protrusion 311 and the second protrusion 312 can be an integral structure.

[0096] Similarly, the connection between the first recess 321 and the second recess 322 can mean that there is no gap between the first recess 321 and the second recess 322. For example, the first recess 321 and the second recess 322 can be integrally formed by cutting or other methods.

[0097] The first protrusion 311 is connected to the second protrusion 312, and the first recess 321 is connected to the second recess 322. During the assembly of the connecting assembly, the first protrusion 311 and the second protrusion 312 can support each other to prevent deformation of the first protrusion 311 and the second protrusion 312.

[0098] In some embodiments, the connection area between the first protrusion 311 and the second protrusion 312 can be an arc-shaped structure. Similarly, the connection area between the first recess 321 and the second recess 322 can also be an arc-shaped structure.

[0099] The connection area between the first protrusion 311 and the second protrusion 312 is an arc-shaped structure, which can alleviate the stress concentration problem on the first connector 310 and facilitate the uniform distribution of the insulating layer on the surfaces of the first protrusion 311 and the second protrusion 312.

[0100] In some embodiments, the first protrusion 311 may include a first end face 3111, which may be one end of the first protrusion 311 that is close to the first recess 321 in a first direction, and the shape of the first end face 3111 may match the shape of the second connector 320.

[0101] For example, such as Figure 2 or Figure 3 In the structure shown, the first connector 310 and the second connector 320 can be annular structures, in which case the first end face 3111 can be an arc surface. Alternatively, the first connector 310 and the second connector 320 can also be rectangular (not shown in the figure), in which case the first end face 3111 can be a plane.

[0102] The shape of the first end face 3111 matches the shape of the second connector 320. During the assembly of the first connector 310 and the second connector 320, the contact area between the first protrusion 311 and the second main body 324 is large, which can alleviate the stress concentration problem on the surface of the second connector 320, thereby alleviating the wear problem on the first end face 3111 and the second connector 320 at the position corresponding to the first end face 3111, and further improving the insulation effect between the first connector 310 and the second connector 320.

[0103] It should be understood that when the second connector 320 is a ring structure, the first end face 3111 can also be a plane, and this application does not limit this.

[0104] In some embodiments, the dimension of the first end face 3111 in the circumferential direction of the first connector 310 may be less than or equal to the dimension of the end of the first protrusion 311 away from the first end face 3111 in the circumferential direction of the first connector 310. The end of the first protrusion 311 away from the first end face 3111 is also the end of the first protrusion 311 that is connected to the first main body portion 314.

[0105] For example, see Figure 10 The enlarged schematic diagram of the first connector 310 shown shows that the side of the first protrusion 311 away from the second protrusion 312 can be an arc surface. The size of the first protrusion 311 along the circumferential direction of the first connector 310 can gradually decrease from the connection position with the first main body 314 to the position of the first end face 3111.

[0106] The dimension of the first end face 3111 in the circumferential direction of the first connector 310 is smaller than the dimension of the end of the first protrusion 311 away from the first end face 3111 in the circumferential direction, which facilitates the assembly of the first connector 310 and the second connector 320, and makes it easier for the first protrusion 311 to enter the first recess 321.

[0107] It should be understood that the side of the first protrusion 311 away from the second protrusion 312 can also be a plane. For example, the dimensions of the first protrusion 311 from the end connected to the first main body 314 to the various positions of the first end face 3111 in the circumferential direction of the first connector 310 can be the same, or they can gradually decrease.

[0108] Accordingly, see also Figure 6 or Figure 7 The partial cross-sectional schematic diagram of the second connector 320 shown shows that, in accordance with the shape of the first protrusion 311, the side of the first recess 321 away from the second recess 322 can also be an arc surface, so that the first protrusion 311 can enter the first recess 321 and be accommodated in the first recess 321.

[0109] See also Figure 5 In some embodiments of the structure shown, the dimension h2 of the second recess 322 in the optical axis direction can be smaller than the dimension h1 of the first recess 321 in the optical axis direction. That is, in the optical axis direction, the second recess 322 can be a convex structure relative to the first recess 321. This optical axis can be an imaginary curve in the optical system, representing the direction in which light is transmitted through the optical system. For symmetrical transmission systems, the optical axis generally coincides with the rotation center line of the optical system. This optical axis direction is also the Z-axis direction shown in the figure.

[0110] The second recess 322 has a dimension h2 in the optical axis direction that is smaller than the first recess 321 has a dimension h1 in the optical axis direction. The second recess 322 can prevent the first protrusion 311 from entering the position of the second recess 322, preventing the first protrusion 311 from contacting the second connector 320 in the first direction, thereby further alleviating the problem of unstable electrical connection of the connector assembly.

[0111] See also Figure 4 In some embodiments of the structure shown, the first connector 310 may further include a third protrusion 313, which may be disposed on the side of the second protrusion 312 away from the first protrusion 311. The dimension of the third protrusion 313 in the first direction may be larger than the dimension of the second protrusion 312 in the first direction. That is, the third protrusion 313 may protrude more than the second protrusion 312.

[0112] Accordingly, see also Figures 5 to 7 As shown in the structure, the second connector 320 may further include a third recess 323, which may be disposed on the side of the second recess 322 away from the first recess 321. The dimension of the third recess 323 in the first direction may be greater than or equal to the dimension of the second recess 322 in the first direction.

[0113] The dimension of the third recess 323 in the first direction is greater than or equal to the dimension of the second recess 322 in the first direction. This can mean that the maximum dimension of the third recess 323 in the first direction is greater than or equal to the maximum dimension of the second recess 322 in the first direction. In other words, in the first direction, the depth of the third recess 323 is the same as the depth of the second recess 322. Figure 6 Alternatively, the depth of the third recess 323 is greater than the depth of the second recess 322. Figure 7 The dimensions of the third protrusion 313 and the third recess 323 in the first direction can be defined similarly to those of the first protrusion 311 and the first recess 321 described above, and will not be repeated here.

[0114] When the connecting assembly is assembled, the third protrusion 313 can be accommodated in the third recess 323, and the third protrusion 313 and the third recess 323 can have a gap in the first direction.

[0115] The first connector 310 also includes a third protrusion 313. During the assembly of the connector assembly, the third protrusion 313 and the first protrusion 311 can jointly protect the second protrusion 312, optimizing the protection effect on the second protrusion 312, preventing wear on the second protrusion 312, and affecting the electrical connection stability between the first connector 310 and the second connector 320. Furthermore, the third protrusion 313 and the first protrusion 311 are respectively disposed on both sides of the second protrusion 312 to protect it, and can also improve the structural stability of the first protrusion 311, the second protrusion 312, and the third protrusion 313, preventing structural deformation during assembly.

[0116] In this example, the third protrusion 313, together with the first protrusion 311 and the second protrusion 312, can be collectively referred to as the male buckle, and the third recess 323, together with the first recess 321 and the second recess 322, can be collectively referred to as the female buckle.

[0117] It should be understood that when the first connector 310 includes a third protrusion 313, the surface of the third protrusion 313 may also be provided with an insulating layer.

[0118] The insulating layer on the surface of the third protrusion 313 can be formed simultaneously with the insulating layers on the surfaces of the first protrusion 311 and the second protrusion 312. For example, the insulating layer can be formed simultaneously on the surfaces of the first protrusion 311, the second protrusion 312 and the third protrusion 313 by the above-mentioned methods such as anodizing, DLC, PVD, etc.

[0119] Similarly, an insulating layer may also be provided on the surface of the third recess 323. The formation method and material of the insulating layer on the surface of the third protrusion 313 and the third recess 323 can be found in the description of the insulating layer above, and will not be repeated here.

[0120] In some embodiments, the difference between the dimension of the third protrusion 313 in the first direction and the dimension of the second protrusion 312 in the first direction may be greater than or equal to 0.1 mm.

[0121] The difference between the dimension of the third protrusion 313 and the dimension of the second protrusion 312 in the first direction is greater than or equal to 0.1 mm, which can improve the protective effect of the third protrusion 313 on the second protrusion 312 during the assembly of the connecting assembly.

[0122] When the first connector 310 includes a third protrusion 313, the dimension of the third protrusion 313 in the first direction may be the same as or different from the dimension of the first protrusion 311 in the first direction. Similarly, the dimension of the third recess 323 in the first direction may be the same as or different from the dimension of the first recess 321 in the first direction.

[0123] When the third protrusion 313 has the same dimension in the first direction as the first protrusion 311 in the first direction, during the assembly of the first connector 310 and the second connector 320, both the first protrusion 311 and the third protrusion 313 can contact the second main body 324, jointly protecting the second protrusion 312. This improves the insulation effect between the first connector 310 and the second connector 320 after assembly, and also enhances the structural stability of the first connector 310, preventing deformation during assembly. Furthermore, the fact that the third protrusion 313 has the same dimension in the first direction as the first protrusion 311 simplifies the processing of the first connector 310, allowing the third protrusion 313 and the first protrusion 311 to be formed simultaneously.

[0124] See also Figure 4 or Figure 10 In some embodiments of the structure shown, the third protrusion 313 may be connected to the second protrusion 312, and correspondingly, the third recess 323 may be connected to the second recess 322.

[0125] The connection between the third protrusion 313 and the second protrusion 312 can mean that there is no gap between the third protrusion 313 and the second protrusion 312. For example, the third protrusion 313, the second protrusion 312, and the first protrusion 311 can be an integral structure.

[0126] Similarly, the connection between the third recess 323 and the second recess 322 can mean that there is no gap between the third recess 323 and the second recess 322. For example, the third recess 323, the second recess 322, and the first recess 321 can be integrally formed by cutting or other means.

[0127] The third protrusion 313 is connected to the second protrusion 312, and the third recess 323 is connected to the second recess 322. During the assembly of the connecting assembly, the third protrusion 313 and the second protrusion 312 can support each other to prevent deformation of the third protrusion 313 and the second protrusion 312.

[0128] The second protrusion 312 can be connected to the first protrusion 311 and the third protrusion 313 respectively, thereby further improving the structural stability of the first protrusion 311, the second protrusion 312 and the third protrusion 313, preventing deformation and affecting the electrical connection stability between the first connector 310 and the second connector 320.

[0129] In some embodiments, the connection area between the third protrusion 313 and the second protrusion 312 can be an arc-shaped structure. Similarly, the connection area between the third recess 323 and the second recess 322 can also be an arc-shaped structure.

[0130] See also Figure 10 In some embodiments of the structure shown, the third protrusion 313 may include a second end face 3131, which may be one end of the third protrusion 313 near the third recess 323 in a first direction, and the shape of the second end face 3131 matches the shape of the second connector 320.

[0131] Similar to the first end face 3111 described above, the first connector 310 and the second connector 320 can be annular as shown in the figure, in which case the second end face 3131 can be an arc surface. Alternatively, the first connector 310 and the second connector 320 can also be rectangular, in which case the second end face 3131 can be a plane.

[0132] The shape of the second end face 3131 matches the shape of the second connector 320. During the assembly of the first connector 310 and the second connector 320, the wear problem of the second end face 3131 and the corresponding position on the second connector 320 can be reduced.

[0133] It should be understood that when the second connector 320 is a ring structure, the second end face 3131 can also be a plane, and this application does not limit this.

[0134] In some embodiments, the dimension of the second end face 3131 in the circumferential direction of the first connector 310 is less than or equal to the dimension of the end of the third protrusion 313 away from the second end face 3131 in the circumferential direction of the first connector 310. The end of the third protrusion 313 away from the first end face 3111 is the end of the third protrusion 313 that is connected to the first main body portion 314.

[0135] For example, see Figure 10The enlarged schematic diagram of the first connector 310 shown shows that the side of the third protrusion 313 away from the second protrusion 312 can be an arc surface. The size of the third protrusion 313 along the circumferential direction of the first connector 310 can gradually decrease from the connection position with the first main body 314 to the position where the second end face 3131 is located.

[0136] The second end face 3131 has a smaller circumferential dimension than the third protrusion 313 at the end away from the second end face 3131 in the circumferential direction, which facilitates the assembly of the first connector 310 and the second connector 320, and makes it easier for the third protrusion 313 to enter the third recess 323.

[0137] It should be understood that the side of the third protrusion 313 away from the second protrusion 312 can also be a plane. For example, the dimensions of the third protrusion 313 from the end connected to the first main body 314 to the various positions of the second end face 3131 in the circumferential direction of the first connector 310 can be the same, or they can gradually decrease.

[0138] Accordingly, see also Figure 6 or Figure 7 The partial cross-sectional schematic diagram of the second connector 320 shown shows that, in accordance with the shape of the third protrusion 313, the side of the third recess 323 away from the second recess 322 can also be an arc surface, so that the third protrusion 313 can enter the third recess 323 and be accommodated in the third recess 323.

[0139] See also Figure 5 In some embodiments of the structure shown, the dimension h2 of the second recess 322 in the optical axis direction may be smaller than the dimension h3 of the third recess 323 in the optical axis direction. That is, in the optical axis direction, the second recess 322 may be a protruding structure relative to the third recess 323.

[0140] The second recess 322 has a dimension h2 in the optical axis direction that is smaller than the third recess 323 has a dimension h3 in the optical axis direction. The second recess 322 can prevent the third protrusion 313 from entering the position of the second recess 322, and prevent the third protrusion 313 from contacting the second connector 320 in the first direction, thereby further alleviating the problem of unstable electrical connection of the connector assembly.

[0141] The above Figures 4 to 10In the described connection assembly, the first connector 310 includes multiple protrusions, and the second connector 320 includes multiple recesses, to improve the structural stability of the connection assembly and prevent deformation or other problems during assembly that could affect the stability of the electrical connection and the reliability of the structure. In this application, the first connector 310 may also include only one protrusion, and correspondingly, the second connector 320 may include only one recess.

[0142] For example, the first connector 310 may include the first protrusion 311 but excludes the second protrusion 312 and the third protrusion 313. Correspondingly, the second connector 320 may include the first recess 321 but excludes the second recess 322 and the third recess 323. When the first protrusion 311 is accommodated within the first recess 321, the first protrusion 311 and the first recess 321 may have a gap in a first direction.

[0143] In this example, during the assembly of the first connector 310 and the second connector 320, the first protrusion 311 comes into contact with the second connector 320. The surface of the first protrusion 311 is prone to wear. When the first protrusion 311 slides to the position of the first recess 321, since there is a gap between the first protrusion 311 and the first recess 321 in the first direction, the first protrusion 311 and the first recess 321 are not prone to unstable electrical connection due to wear.

[0144] In some embodiments, the first connector 310 may include a plurality of male buckles, which may be spaced apart on the side of the first main body 314 near the second connector 320. Similarly, the second connector 320 may include a plurality of female buckles, which may be spaced apart on the side of the second main body 324 near the first connector 310. Alternatively, the first connector 310 may include a plurality of first protrusions 311, second protrusions 312, and third protrusions 313, and the second connector 320 may include a plurality of first recesses 321, second recesses 322, and third recesses 323.

[0145] When the first connector 310 includes multiple male buckles, the multiple male buckles can be evenly distributed on the side of the first main body 314 near the second connector 320. When the second connector 320 includes multiple female buckles, the multiple female buckles can be evenly distributed on the side of the second main body 324 near the first connector 310, and the positions of the multiple female buckles can correspond to the positions of the multiple male buckles, so that the multiple male buckles can be engaged with the multiple female buckles respectively.

[0146] In some embodiments, the side of the first protrusion 311, the second protrusion 312, and the third protrusion 313 away from the back cover in the optical axis direction can be a wedge surface. In other words, the size of the first protrusion 311 in the optical axis direction can gradually decrease from the end of the first protrusion 311 connected to the first main body 314 to the position of the first end face 3111. The second protrusion 312 and the third protrusion 313 are similar.

[0147] During the assembly of the connecting component, when the first connector 310 moves to the position of the first recess 321, the sides of the first protrusion 311, the second protrusion 312, and the third protrusion 313 away from the back cover in the optical axis direction are wedge surfaces, which facilitates the first protrusion 311, the second protrusion 312, and the third protrusion 313 entering the first recess 321, the second recess 322, and the third recess 323 respectively, thereby achieving the engagement of the first connector 310 and the second connector 320.

[0148] In some embodiments, the first connector 310 may further include a platform 315, which, along with the first protrusion 311 and the second protrusion 312, may be respectively disposed at both ends of the first main body 314 along the optical axis, and the projection of the platform 315 along the optical axis may overlap with at least a portion of the second connector 320. When the first connector 310 and the second connector 320 are assembled, the platform 315 may contact one end of the second connector 320 along the optical axis.

[0149] In some embodiments, the first connector 310 and the second connector 320 can also be connected by adhesive bonding to make the connection between the first connector 310 and the second connector 320 more stable.

[0150] For example, the second connector 320 may include a dispensing groove, which may be disposed along the optical axis at one end of the second connector 320 away from the back cover. The projection of the platform 315 along the optical axis may overlap with at least a portion of the dispensing groove. Adhesive may be disposed in the dispensing groove. The first connector 310 may be bonded to the second connector 320 through the platform 315.

[0151] Similarly, the end of the first connector 310 near the rear cover along the optical axis can also be bonded to the second connector 320, or the first connector 310 and the second connector 320 can also be bonded through the first main body portion 314 and the second main body portion 324. This application does not limit this.

[0152] It should be understood that in this application, adhesive can also be applied between the first main body 314 and the second main body 324 to fix the first connector 310 and the second connector 320 to each other, thereby improving the structural stability after fastening. This application does not limit the location of the adhesive application.

[0153] See also Figure 3 In some embodiments of the structure shown, the first connector 310 may further include a first dustproof net 3141, which may be disposed on the first main body 314 along the circumferential direction of the first connector 310. The first dustproof net 3141 may be composed of a plurality of periodically arranged first through holes on the first main body 314.

[0154] The number of the first dustproof net 3141 can be one or more. For example, the number of the first dustproof net 3141 can be one, and the first dustproof net 3141 can be disposed on the entire first main body 314 along the circumferential direction of the first connector 310, or the first dustproof net 3141 can be disposed in a portion of the first main body 314 along the circumferential direction of the first connector 310. As another example, the number of the first dustproof net 3141 can be multiple, and the multiple first dustproof nets 3141 can be disposed at intervals along the circumferential direction of the first connector 310.

[0155] Accordingly, the second connector 320 may include an opening 3241, which may be disposed on the second main body 324 along the circumferential direction of the second connector. The projection of the first dustproof mesh 3141 along the first direction may overlap with at least a portion of the opening 3241, so that heat can be transferred to the outside of the electronic device through the opening 3241 and the first dustproof mesh 3141 respectively. For example, the opening 3241 may be disposed opposite to the first dustproof mesh 3141 along the first direction.

[0156] The number of openings 3241 can be one or more. When there is only one opening 3241, the opening 3241 can be provided in a portion of the second main body 324 in the circumferential direction. When there are multiple openings 3241, the multiple openings 3241 can be spaced apart in the circumferential direction of the second connector 320.

[0157] The first connector 310 includes a first dustproof mesh 3141, and the second connector 320 includes an opening 3241. When this connector is applied to an electronic device, it can optimize the heat dissipation of electronic components in the electronic device and prevent external dust and other contaminants from entering the electronic device and affecting its operation.

[0158] Figure 11 This application provides another structure for a connecting component, such as... Figure 11As shown, in some embodiments, the second connector 320 may include a second dustproof mesh 3242 instead of the aforementioned opening 3241. The second dustproof mesh 3242 may be disposed on the second main body portion 324 along the circumferential direction of the second connector 320. The second dustproof mesh 3242 may be composed of a plurality of periodically arranged second through holes on the second main body portion 324.

[0159] Similar to the first dustproof net 3141, the number of the second dustproof net 3242 can also be one or more. Figure 11 (The number of second dustproof nets 3242 is illustrated as an example of multiple nets).

[0160] When the first connector 310 includes a first dustproof net 3141 and the second connector 320 includes a second dustproof net 3242, the first dustproof net 3141 and the second dustproof net 3242 can be arranged opposite to each other along a first direction. Alternatively, the first through hole and the second through hole can be arranged opposite to each other along the first direction, or they can be staggered along the first direction. The first through hole and the second through hole being arranged opposite to each other along the first direction can mean that the projection of the center of the first through hole onto the second connector 320 along the first direction overlaps with the center of the second through hole; the first through hole and the second through hole being staggered along the first direction can mean that the projection of the center of the first through hole onto the second connector 320 along the first direction has a distance between it and the center of the second through hole.

[0161] The second connector 320 includes a second dustproof net 3242, which can cooperate with the first dustproof net 3141 to optimize the dustproof effect and prevent dust and other external debris from entering the electronic device.

[0162] When the first connector 310 and the second connector 320 include a dustproof net, when applying adhesive between the first main body 314 and the second main body 324, the adhesive can avoid the dustproof net.

[0163] It should be understood that the above Figure 2 , Figure 3 as well as Figure 11 The connecting component shown is a circular ring structure. When this connecting component is used in a camera module, it can also be a rectangular, triangular, or other ring structure; this application does not limit this. When the connecting component is a rectangular structure, the aforementioned first direction can be perpendicular to the sides where the first protrusion 311 and the second protrusion 312 are located. Similarly, when the connecting component is a triangular structure, the first direction can be perpendicular to the sides where the first protrusion 311 and the second protrusion 312 are located.

[0164] Figures 3 to 11In the structure shown, the first connector 310 is disposed outside the second connector 320. The connecting assembly provided in this application can also have the second connector 320 disposed outside the first connector 310. When the second connector 320 is disposed outside the first connector 310, the first recess 321, the second recess 322, and the third recess 323 can be disposed on the side of the second connector 320 near the first connector 310, and the first protrusion 311, the second protrusion 312, and the third protrusion 313 can be disposed on the side of the first connector 310 near the second connector 320.

[0165] When the second connector 320 is disposed outside the first connector 310, in order to achieve a smooth shape for the connecting assembly, the second connector 320 needs to have a large thickness (i.e., the dimension in the first direction) so that the second connector 320 has sufficient space to support the formation of the recess, resulting in the connecting assembly occupying a large structural space. Furthermore, by disposing the first connector 310 outside the second connector 320, and having the first protrusion 311, the second protrusion 312, and the third protrusion 313 extend towards the direction of the second connector 320, the aesthetics of the connecting assembly can be improved, and the structural space occupied by the connecting assembly can be reduced.

[0166] This application also provides a camera module, which may include the above-mentioned connecting component, lens assembly, and protective cover. The protective cover can be connected to the second connector 320, and a portion of the lens assembly can be disposed in the receiving space enclosed by the protective cover and the connecting component.

[0167] The first protrusion 311 and the second protrusion 312 can be disposed along the optical axis at the end of the first connector 310 away from the protective cover plate.

[0168] Accordingly, the first recess 321 and the second recess 322 can be provided at the end of the second connector 320 away from the protective cover plate, so that the first protrusion 311 and the second protrusion 312 can be respectively accommodated in the first recess 321 and the second recess 322.

[0169] Similarly, when the first connector 310 includes a third protrusion 313 and the second connector 320 includes a third recess 323, the third protrusion 313 may also be disposed along the optical axis at the end of the first connector 310 away from the protective cover plate, and the third recess 323 may be disposed along the optical axis at the end of the second connector 320 away from the protective cover plate.

[0170] The first protrusion, the second protrusion 312, and the third protrusion 313 are disposed along the optical axis at one end of the first connector 310 away from the protective cover plate, and the first recess 321, the second recess 322, and the third recess 323 are disposed along the optical axis at one end of the second connector 320 away from the protective cover plate, which can further improve the structural stability of the connecting assembly.

[0171] This application also provides an electronic device that may include the aforementioned camera module and a back cover, wherein the aforementioned second connector 320 may be connected to the back cover. The back cover and the protective cover may be respectively connected to the two ends of the second connector 320 along the optical axis.

[0172] The second connector 320 can be connected to the back cover as two independent structural components, fixedly connected by means of adhesive bonding, welding, or other methods. Alternatively, the second connector 320 and the back cover can be an integral structure. An integral structure between the second connector 320 and the back cover improves the waterproof performance of the electronic device.

[0173] For example, the electronic device can be a mobile phone, tablet computer, laptop computer, large-screen device (such as a TV), wearable device (such as a watch) with photo and / or video recording functions.

[0174] It should be understood that the above-mentioned camera module and electronic device are only examples illustrating the application scenarios of the connection component provided in this application. The connection component can also be applied to other scenarios that require stable electrical connection (such as stable insulation), and this application does not limit it.

[0175] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
