Description

[Technical Field]

[0001] The present embodiment relates to a circuit board fixing device for a camera module and a camera module including the same.

[0002] This embodiment relates to a camera module having a structure capable of preventing degradation of image quality and electromagnetic compatibility (EMC) due to static electricity. [Background technology]

[0003] The following description merely provides background information for the present embodiment and is not intended to describe the prior art.

[0004] Nowadays, not only small IT devices such as smartphones, tablet PCs, and game consoles, but also vehicles are equipped with camera modules for driving records and parking convenience.

[0005] In recent years, camera modules installed in vehicles perform various additional functions in addition to the function of displaying images. As a result, various elements are mounted on the camera module along with the image sensor, and as a result, the size of the circuit board used in the camera module is gradually increasing.

[0006] However, since the size of a camera module is limited, in recent years, a technology has been developed in which multiple small circuit boards are stacked inside a camera module in order to meet both the limited size of the camera module and the required area of ​​the circuit board.

[0007] Korean Patent Publication No. 0-2010-0048101, Camera Module for Automobiles (published on May 11, 2010), discloses a technology in which multiple circuit boards are stacked inside a camera module and each circuit board is connected to a housing with a fastening screw.

[0008] However, in the automotive camera module, the circuit board is connected to the housing by fastening screws, which may result in an increase in the number of assembly steps due to the fastening screws, an increase in production costs due to the fastening screws, a reduction in the component mounting area on the circuit board due to the use of more circuit boards, and warping of the circuit board due to screw fastening.

[0009] Meanwhile, a camera module for various purposes may be installed in a vehicle. For example, when parking a vehicle, a camera module that can ensure a rearward field of view may be installed in the rear of the vehicle.

[0010] Furthermore, camera modules can also be used in automobile black boxes, which are very useful for tracing the circumstances and causes of traffic accidents in recent years. Furthermore, there is a gradual trend toward using camera modules as recognition devices that allow automobile drivers or passengers to clearly and easily grasp the situation in blind spots that are difficult for the naked eye to see.

[0011] In recent years, there has been an increase in the production of so-called smart cars, that is, cars equipped with collision warning systems that detect the possibility of a front or rear collision while the car is moving and prepare for it, and collision avoidance systems that use a control device installed in the car to directly avoid collisions between cars while the car is moving without the driver's help, and there is a tendency for the development of related technologies to increase.

[0012] The use of camera modules as a means of external situational awareness for such smart cars is increasing, and as a result, the production and technological development of automotive camera modules is also on the rise. Summary of the Invention [Problem to be solved by the invention]

[0013] This embodiment provides a circuit board fixing device for a camera module, which prevents an increase in the number of assembly steps, reduces production costs, prevents a reduction in component mounting area on the circuit board, and prevents warping of the circuit board by firmly fixing the circuit board inside the housing without using fastening screws, and a camera module including the same.

[0051] First, the camera modules of the first and second embodiments will be described.

[0052] Fig. 1 is a perspective view of the appearance of a camera module according to the first embodiment, and Fig. 2 is a cross-sectional view taken along line II' in Fig. 1.

[0053] Referring to FIGS. 1 and 2, the camera module 700 of the first embodiment may include a circuit board fixing device 100, an image sensor 200, a lens 300, a lens barrel 400, and a housing 500.

[0054] FIG. 3 is a perspective view illustrating the circuit board fixing device illustrated in FIG.

[0055] Referring to FIG. 3, the circuit board fixing device 100 can include a fixing unit 180 for fixing multiple circuit boards 110 .

[0056] The circuit board 110 according to the first embodiment can be firmly fixed by the fixing unit 180 .

[0057] In this first embodiment, for example, four circuit boards 110 can be fixed to the fixing unit 180 .

[0058] For convenience of explanation, the circuit board 110 will be divided into a first circuit board 112, a second circuit board 114, a third circuit board 116, and a fourth circuit board 118.

[0059] The first through fourth circuit boards 112, 114, 116, and 118 may each include a rigid circuit board.

[0060] In the first embodiment of the present invention, the first circuit board 112, the second circuit board 114, the third circuit board 116 and the fourth circuit board 118 are connected in a row by flexible circuit boards 113, 115 and 117.

[0061] The first and second circuit boards 112, 114, the second and third circuit boards 114, 116, and the third and fourth circuit boards 116, 118 can be electrically connected to each other by flexible circuit boards 113, 115, 117, respectively.

[0062] The first to fourth circuit boards 112, 114, 116, and 118 may have grooves formed therein to prevent the flexible circuit boards 113, 115, and 117 from bending.

[0063] The first to fourth circuit boards 112, 114, 116, and 118 may be stacked in a zigzag pattern. For example, the second circuit board 114 may be arranged on top of the first circuit board 112, the third circuit board 116 may be arranged on top of the second circuit board 114, and the fourth circuit board 118 may be arranged on top of the third circuit board 116.

[0064] The stacked first to fourth circuit boards 112, 114, 116, 118 are spaced apart from one another by a predetermined distance, and the distances between the first to fourth circuit boards 112, 114, 116, 118 may be the same or different from one another.

[0065] On the other hand, the planar area of ​​the third circuit board 116 may be larger than the planar area of ​​the second circuit board 114, and the planar area of ​​the fourth circuit board 118 may be larger than the planar area of ​​the third circuit board 116.

[0066] In this first embodiment, the image sensor 200 can be mounted on the first circuit board 112, and a connector or the like can be mounted on the fourth circuit board 118.

[0067] FIG. 4 is a perspective view illustrating a fixing unit of the circuit board fixing device illustrated in FIG.

[0068] 3 and 4, the fixing unit 180 serves to fix the circuit board 110 including the first to fourth circuit boards 112, 114, 116, and 118 without using screws.

[0069] The fixing unit 180 may include a base portion 120 , a first fixing portion 130 and a second fixing portion 140 .

[0070] In one embodiment of the present invention, the base portion 120, the first fixing portion 130 and the second fixing portion 140 of the fixing unit 180 may be integrally formed, for example.

[0071] Although in one embodiment of the present invention, the base portion 120, the first fixing portion 130, and the second fixing portion 140 are shown and described as being integrally formed, the base portion 120, the first fixing portion 130, and the second fixing portion 140 may be assembled or welded separately from each other.

[0072] The base portion 120 may be formed, for example, in a plate shape, and may be coupled and fixed to a housing 500, which will be described later.

[0073] The shape of the base part 120 is determined by the shape of the housing 500. When the housing 500 is hexahedral, the base part 120 may be formed in the shape of a square plate suitable for being housed in the housing 500, for example.

[0074] An opening 122 may be formed in the center of the base 120 to allow a connector or the like to pass through.

[0075] At least one first fixing portion 130 may extend from the rim of the base portion 120 to one side of the base portion 120 .

[0076] In one embodiment of the present invention, the first fixing portions 130 may extend in a first direction from opposite side frames of the base portion 120 to face each other. The first direction may be, for example, a height direction relative to the base portion 120. The first direction may be a direction perpendicular to the base portion 120, and may be formed by extending in a direction perpendicular to a corner or frame of the base portion 120.

[0077] The first fixing portion 130 may be formed, for example, in a rectangular plate shape. Although the first fixing portion 130 is illustrated and described as having a rectangular plate shape in the first embodiment, the first fixing portion 130 may be formed in various plate shapes.

[0078] The first fixing portion 130 may include support portions 132, 133, and 134 that protrude in a direction perpendicular to a first direction, which is the height direction relative to the base portion 120.

[0079] The support portions 132, 133, and 134 serve to prevent the second to fourth circuit boards 114, 116, and 118 from being separated. The support portions 132, 133, and 134 of the first fixing portion 130 may be referred to as protrusions of the first fixing portion 130. That is, the first fixing portion 130 may include a plurality of protrusions extending in a first direction from the base portion 120 and protruding in a direction perpendicular to the first direction to support one side of each of the plurality of boards 110.

[0080] The number of support portions 132, 133, and 134 is determined by the number of circuit boards 110. In this first embodiment, for example, three support portions 132, 133, and 134 may be formed on the first fixing portion 130 to support one side of the second to fourth circuit boards 114, 116, and 118, excluding the first circuit board 112, arranged on the base portion 120. In this specification, one side of a circuit board may be the upper surface (or lower surface) of the circuit board, and the other side of the circuit board may be the lower surface (or upper surface) of the circuit board.

[0081] The support portions 132 that support the second circuit board 114 can be formed by bending the portions protruding from both side surfaces of the first fixing portion 130 toward the lower surface of the second circuit board 114, for example.

[0082] The support parts 133 that support the third circuit board 116 can be formed by bending the parts protruding from both side surfaces of the first fixing part 130 toward the lower surface of the third circuit board 116, for example.

[0083] The support portion 134 that supports the fourth circuit board 118 can be formed, for example, by cutting out a portion of the first fixing portion 130 and allowing the cut-out portion to protrude from the outside to the inside of the first fixing portion 130.

[0084] In the first embodiment, in order to arrange the second to fourth circuit boards 114, 116, and 118 in a zigzag pattern, the protruding lengths of the support portions 132, 133, and 134 that support the lower surfaces of the second to fourth circuit boards 114, 116, and 118, respectively, may become shorter in a discontinuous manner as they move away from the base portion 120. The size of the boards supported by the support portions 134 may be determined according to the protruding lengths of the support portions 132, 133, and 134. The protruding lengths of the support portions 132, 133, and 134 become shorter as they move away from the base portion 120, and accordingly, the size of the boards in a direction perpendicular to the first direction may also become smaller as they move away from the base portion 120.

[0085] Furthermore, the second to fourth circuit boards 114, 116, and 118 may be formed with relief grooves so that the second to fourth circuit boards 114, 116, and 118 can be coupled without interference with the support portions 132, 133, and 134. The area of ​​the relief groove may be largest in the second circuit board 114 and smallest in the fourth circuit board 118.

[0086] 3 and 4, the second fixing portion 140 prevents the second to fourth circuit boards 114, 116, and 118, respectively supported by the support portions 132, 133, and 134 of the first fixing portion 130, from coming off upward.

[0087] The second fixing portions 140 may be arranged in the first direction, for example, so that a pair of second fixing portions 140 face each other relative to the base portion 120 .

[0088] Therefore, the second fixed portion 140 can be arranged so as to be parallel to the first fixed portion 130 and so as to be perpendicular to the first fixed portion 130 in a plan view.

[0089] When the second fixing portion 140 is arranged in pair with the first fixing portion 130 on the base portion 120, the first and second fixing portions 130, 140 stably fix the second to fourth circuit boards 114, 116, 118 at four points, thereby preventing the second to fourth circuit boards 114, 116, 118 from coming off or moving up and down.

[0090] The second fixing portion 140 can be formed from the frame of the base portion 120 in the first direction.

[0091] The second fixing portion 140 may be formed, for example, in a rectangular plate shape when viewed from the side. Although the first embodiment illustrates and describes the second fixing portion 140 as being formed in a rectangular plate shape, the second fixing portion 140 may have various plate shapes.

[0092] The width of the second fixing portion 140 is narrower than the width of the first fixing portion 10, in order to prevent the portion where the second fixing portion 140 is formed from interfering with the flexible circuit boards 113, 115, and 117 that connect the first to fourth circuit boards 112, 114, 116, and 118.

[0093] The second fixing portion 140 has protrusions 143, 143, and 144 formed along the height direction relative to the base portion 120. The second fixing portion 140 may include a plurality of protrusions extending in a first direction from the base portion 120 to support or contact the other sides of each of the plurality of substrates 110. The first direction may be a direction perpendicular to the base portion 120. The protrusions 142, 143, and 144 are formed at positions corresponding to the second to fourth circuit boards 114, 116, and 118, excluding the first circuit board 112, which are disposed on the upper surface of the base portion 120.

[0094] In this first embodiment, the protrusion 142 formed on the second fixing portion 140 contacts or presses against the upper surface of the second circuit board 114, and the second circuit board 114 is prevented from moving up and down by the support portion 132 of the first fixing portion 130 and the protrusion 142 of the second fixing portion 140.

[0095] The protrusion 142 for fixing the second circuit board 114 can be formed by cutting out a portion of the second fixing portion 140 and then bending the cut-out portion toward the top surface of the second circuit board 114.

[0096] In this first embodiment, the protrusion 143 formed on the second fixing part 140 contacts or presses against the upper surface of the third circuit board 116, and the third circuit board 116 is prevented from moving up and down by the support part 133 of the first fixing part 130 and the protrusion 143 of the second fixing part 140.

[0097] The protrusion 143 for fixing the third circuit board 116 can be formed by cutting out a part of the second fixing part 140 and then bending the cut-out part toward the top surface of the third circuit board 116.

[0098] In this second embodiment, the protrusion 144 formed on the second fixing part 140 contacts or presses against the upper surface of the fourth circuit board 118, and the fourth circuit board 118 is prevented from moving up and down by the support part 134 of the first fixing part 130 and the protrusion 144 of the second fixing part 140.

[0099] The protrusion 144 for fixing the fourth circuit board 118 can be formed by cutting a portion of the second fixing portion 140 and then bending the cut portion toward the top surface of the fourth circuit board 118.

[0100] In this first embodiment, the second to fourth circuit boards 114, 116, and 118 fixed by the protrusions 142, 143, and 144 have gradually increasing planar areas as described above, so that a step portion may be formed between each of the protrusions 142, 143, and 144 in the second fixing part 140 in consideration of the planar areas of the second to fourth circuit boards 114, 116, and 118.

[0101] Figure 5 is a perspective view illustrating a fixing unit for a camera module according to the second embodiment. The fixing unit illustrated in Figure 5 has substantially the same configuration as the fixing units illustrated in Figures 2 to 4, except for the shapes of the support portion and protrusion. Therefore, duplicated descriptions of the same components will be omitted, and the same names and reference numerals will be used for the same components.

[0102] Referring to FIG. 5, the fixing unit 180 may include a base portion 120 , a first fixing portion 130 and a second fixing portion 140 .

[0103] The first fixing portion 130 may include support portions 132 a , 133 a , and 134 a formed along the height direction relative to the base portion 120 .

[0104] The support portions 132a, 133a, and 134a may be formed by cutting out a portion of the first fixing portion 130 and protruding the cut-out portion from the outer surface of the first fixing portion 130 toward the inner surface opposite the outer surface, and the support portions 132a, 133a, and 134a support the lower surfaces of the second to fourth circuit boards 114, 116, and 118.

[0105] The second fixing portion 140 may include protrusions 142 a , 143 a , and 144 a formed along the height direction relative to the base portion 120 .

[0106] The protrusions 142a, 143a, and 144a may be formed by cutting out a portion of the second fixing part 140 and protruding the cut-out portion from the outer surface of the second fixing part 140 toward the inner surface opposite the outer surface, and the protrusions 142a, 143a, and 144a may come into contact with the upper surfaces of the second to fourth circuit boards 114, 116, and 118.

[0107] Fig. 6 is an exploded perspective view illustrating a fixing cap coupled to a fixing unit according to a first embodiment of the present invention, and Fig. 7 is an assembled perspective view of Fig. 6.

[0108] 6 and 7, when the first and second fixing portions 130 and 140 of the fixing unit 180 are opened while the first to fourth circuit boards 112, 114, 116, and 118 are coupled to the first and second fixing portions 130 and 140, the first to fourth circuit boards 112, 114, 116, and 118 can be detached from the first and second fixing portions 130 and 140.

[0109] To prevent this, the fixing unit 180 may include a fixing cap 150. The fixing cap 150 may be coupled to the first and second fixing portions 130, 140 of the fixing unit 180 to prevent the first and second fixing portions 130, 140 from opening.

[0110] The fixing cap 150 can be made of various materials such as a metal material that is highly rigid and easy to process, or a synthetic resin material that is easy to process and can be molded into a complex shape.

[0111] The fixed cap 150 is formed in a lid shape, and may include a side wall 155 and an upper plate 159 .

[0112] The upper plate 159 may be formed in a shape corresponding to the base portion 120 of the fixing unit 180, for example.

[0113] For example, if the base portion 120 is formed in a square plate shape, the upper plate 159 is also formed in a shape corresponding to the base portion 120, and in one embodiment of the present invention, the upper plate 159 may be formed in a square plate shape.

[0114] The upper plate 159 may have an opening 158 formed therein that exposes a connector that is connected to the fourth circuit board 118 fixed to the fixing unit 180 .

[0115] Meanwhile, a detachment prevention portion 157 may be formed around the opening 158 formed in the upper plate 159, which is bent inward of the upper plate 159 to contact or press the upper surface of the fourth circuit board 118 to further prevent or inhibit the detachment of the fourth circuit board 118.

[0116] The frame of the upper plate 159 may be integrally formed with side walls 155, which contact the outer surfaces of the first and second fixing parts 130, 140, respectively, to prevent the first and second fixing parts 130, 140 from opening.

[0117] Meanwhile, the side wall 155 may be formed with a locking portion 151 to be coupled with the first and second fixing portions 130 and 140, for example.

[0118] The locking portion 151 is formed by cutting and bending a portion of the side wall 155, and a through hole 137 may be formed in the first fixing portion 130 corresponding to the locking portion 151 to be coupled to the locking portion 151 in a hook manner.

[0119] The sidewall 155 may have at least one warp prevention rib 152 formed thereon to prevent the sidewall 155 from warping.

[0120] 8 to 10 are diagrams illustrating the order in which the first to fourth circuit boards are assembled to the first and second fixing portions of the fixing unit according to the first embodiment.

[0121] Referring to FIG. 8, a first circuit board 112 can be fixed and coupled to the base portion 120 of the fixing unit 180 .

[0122] Thereafter, as shown in FIG. 9, the second circuit board 114 is coupled to the first and second fixing portions 130 and 140, respectively, so as to face the first circuit board 112, and as shown in FIG. 10, the third circuit board 116 is coupled to the first and second fixing portions 130 and 140, so as to face the second circuit board 114.

[0123] Thereafter, as shown in FIG. 3, the fourth circuit board 118 is coupled to the first and second fixing parts 130 and 140 so as to face the third circuit board 116 .

[0124] Referring again to FIG. 2, the circuit board fixing device 100 including the fixing unit 180 described with reference to FIGS. 3 to 8 is coupled to the inside of the housing 500, and the lens assembly 400 to which the lens 300 is coupled is coupled to the housing 500.

[0125] As described above in detail, the circuit board fixing device for a camera module according to the first and second embodiments and the camera module having the same firmly fix the circuit board inside the housing without using fastening screws, thereby preventing an increase in the number of assembly steps, reducing production costs, preventing a reduction in the component mounting area on the circuit board, and preventing warping of the circuit board.

[0126] The camera module of the third embodiment will now be described.

[0127] Fig. 11 is a perspective view showing a camera module of the third embodiment, Fig. 12 is an exploded perspective view showing a camera module of the third embodiment, and Fig. 13 is a front view showing a camera module of one embodiment.

[0128] The camera module of this third embodiment may include a lens unit 1100, a front body 1200, a base unit 1300, a first fence 1400, a second fence 1500, an image sensor 1700, a fastening mechanism 1810, a sealing member 1820, and a cable connection unit 1830.

[0129] The lens unit 1100 is a portion where external light is incident and may include a lens barrel to which at least one lens is attached. In this case, the lens barrel may be configured with a single lens, or may include multiple lenses aligned in the optical axis direction, i.e., the first direction. In another embodiment, one or multiple lenses may be directly coupled to the front body 1200 without a lens barrel.

[0130] Furthermore, since the lens unit 1100 may be connected to the front body 1200 by screw connection, form fitting, interference fitting, or other methods, a sealing member 1820 may be provided to prevent moisture, dust, and other foreign matter from entering the interior of the camera module through gaps at the connection points between the lens unit 1100 and the front body 1200.

[0131] As shown in FIG. 12, the sealing member 1820 is disposed at a joining portion between the lens part 1100 and the front body 1200, and may be provided in the form of, for example, an O-ring.

[0132] The front body 1200 may be hollow and accommodate the lens unit 1100 in its internal space. The lens unit 1100 may be attached to the front part of the front body 1200. For this purpose, the front body 1200 may have a hollow in which the lens unit 1100 is attached.

[0133] The front body 1200 may be coupled to a housing (not shown). The coupling between the front body 1200 and the housing may be performed, for example, by a coupling mechanism (not shown). To this end, as shown in Figures 11 and 12, a through-hole into which the coupling mechanism is inserted may be formed at a corner of the front body 1200.

[0134] However, this is merely one embodiment, and in other embodiments, the front body 1200 and the housing may be joined by adhesive, form-fitting, or interference fitting without using a joining mechanism.

[0135] The cable connection unit 1830 may serve to connect an external cable to the substrate unit 1300. The camera module may receive power from an external device or transmit and receive electrical signals to and from an external device through an external cable (not shown) electrically connected to the cable connection unit 1830.

[0136] The cable connecting portion 1830 may include a first connecting portion 1831 and a second connecting portion 1832. The first connecting portion 1831 may be coupled to the base portion 1300, and the second connecting portion 1832 may be coupled to the first connecting portion 1831 and the external cable.

[0137] 13, the first connecting portion 1831 may be connected to the third substrate 1313 disposed at the rear end of the substrate unit 1300, the second connecting portion 1832 may be connected to the first connecting portion 1831, and the external cable may be connected to the second connecting portion 1832. With this structure, the substrate unit 1300 and the external cable may be electrically connected to each other.

[0138] The board unit 1300 may be disposed at the rear side of the front body 1200 and may include a plurality of printed circuit boards 1310. The board unit 1300 may include the printed circuit boards 1310 and a connector 1320.

[0139] As shown in Fig. 12, a plurality of printed circuit boards 1310 may be arranged spaced apart from each other in the optical axis direction. A plurality of printed circuit boards 1310 may be arranged facing the lens unit 1100. In Fig. 12, four printed circuit boards 310 are provided as an example, but the number of printed circuit boards 1310 may be less than four or more than four.

[0140] 11 to 13, a substrate unit 1300 including a printed circuit board 1310 according to a third embodiment will be described. The printed circuit board 1310 may include a first substrate 1311, a second substrate 1312, and a third substrate 1313.

[0141] The first substrate 1311 may be disposed to face the lens unit 1100. The third substrate 1313 may be disposed to be spaced apart from the first substrate 1311 in the optical axis direction. The second substrate 1312 may be disposed between the first substrate 1311 and the third substrate 1313 to be spaced apart from the first substrate 1311 and the third substrate 1313, respectively.

[0142] In this case, the second substrate 1312 may include, for example, a second -1 substrate 1312-1 arranged adjacent to the first substrate 1311 and a second -2 substrate 1312-2 arranged adjacent to the third substrate 1313, but is not limited thereto, and the second substrate 1312 may be provided in a form in which one substrate or three or more substrates are arranged in the optical axis direction.

[0143] The first substrate 1311 faces the lens unit 1100, but can be disposed adjacent to the lens unit 1100, and an image sensor 1700 can be mounted on the surface facing the lens unit 1100, i.e., the front surface, and an electromagnetic circuit including various other circuit elements can be formed.

[0144] The image sensor 1700 senses light incident through the lens unit 1100, and the first substrate 1311 converts the sensed image into an electrical signal and transmits it to an external image storage device or image playback device. However, the conversion of the sensed image into an electrical signal can also be performed by a separate substrate.

[0145] The second substrate 1312, including the second-1 substrate 1312-1 and the second-2 substrate 1312-2, is disposed between the first substrate 1311 and the third substrate 1313 and can be electrically connected to the first substrate 1311 and the third substrate 1313 to form an electromagnetic circuit.

[0146] The second -1 substrate 1312-1 and the second -2 substrate 1312-2 may serve as an electrical path to supply the necessary power to the first substrate 1311, and may also serve to transmit the electrical signal for the sensed image transmitted from the first substrate 1311 to an external image storage device or image reproduction device.

[0147] For example, the second -1 board 1312-1 and / or the second -2 board 1312-2 may convert the sensed image transmitted from the first board 1311 into an electrical signal and transmit it to an external image storage device or image playback device, or may rectify the power input from the third board 1313 and transmit it to the first board 1311.

[0148] That is, the second -1 substrate 1312-1 and / or the second -2 substrate 1312-2 may be arranged between the first substrate 1311 and the third substrate 1313 and may partially share the roles performed by the first substrate 1311 and the third substrate 1313.

[0149] The third board 1313 may be disposed behind the second board 1312 and electrically connected to the second board 1312 to form an electromagnetic circuit. As described above, the third board 1313 may be electrically connected to the cable connecting portion 1830 and an external cable.

[0150] The third board 1313 mainly serves to receive power required for the operation of the camera module from the outside and transmit it to the first board 1311 and the second board 1312, and to transmit electrical signals for sensed images transmitted from the first board 1311 and the second board 1312 to an external image storage device or image playback device.

[0151] Therefore, elements such as a capacitor, rectifier, transformer, etc. for supplying power with the appropriate voltage and current required for the operation of the camera module may be mounted on the third board 1313. Furthermore, the cable connection part 1830 may be coupled to the third board 1313 as described above for electrical connection with an external image storage device, image playback device, camera module control device, etc.

[0152] The connector 1320 electrically connects the plurality of printed circuit boards 1310 to each other and may be made of a flexible material. The connector 1320 may serve to electrically connect the printed circuit boards 1310, i.e., the first board 1311, the second-1 board 1312-1, the second-2 board 1312-2, and the third board 1313. Since the connector 1320 electrically connects each board to each other, the number of connectors 1320 may be one less than the number of printed circuit boards 1310.

[0153] In this third embodiment, referring to FIG. 17, the printed circuit board 1310 is provided with a total of four boards, namely, a first board 1311, a second-1 board 1312-1, a second-2 board 1312-2, and a third board 1313, and therefore the number of connectors 1320 can be three, one less than these.

[0154] Referring to Figures 12 and 17, in the embodiment, connectors 1320 that connect each board to each other are provided on the side of each board, but this is not limited to this, and the number and placement positions of the connectors 1320 can be selected taking into consideration the circuit structure of each board and the overall structure of the camera module.

[0155] It is appropriate for the connector 1320 to be made of a flexible material in consideration of the ease of connection to each board and the need to absorb shocks and vibrations applied to the outside of the camera module to prevent damage from such shocks and vibrations. Thus, the connector 1320 can be made of a flexible circuit board.

[0156] However, the present invention is not limited to this, and any sturdy material that is resistant to shock and vibration may be used, and connector 1320 may be formed using a bundle of electric wires.

[0157] Furthermore, soldering, adhesive bonding using an electrically conductive adhesive, etc. may be used to connect the connector 1320 to each board, and such a connector 1320 may serve as a B2B (board to board) connector 1320 that electrically connects each board.

[0158] The first fence 400 may be coupled to the substrate unit 300 and serve to space the printed circuit boards 310 apart from each other in the optical axis direction. The first fence 400 will be described in detail below with reference to the accompanying drawings.

[0159] Fig. 14 is a perspective view showing a portion of a camera module according to a third embodiment. Fig. 15 is a front view of Fig. 14. A second fence 1500 is coupled to the first fence 1400 at the rear side of the first fence 1400 and is electrically connected to the substrate unit 1300 to serve to ground the substrate unit 1300.

[0160] When power is supplied to the camera module from an external power source, static electricity may be generated in the camera module, and in particular, static electricity generated in the substrate unit 1300 may adversely affect the performance of the camera module.

[0161] For example, static electricity generated in the substrate unit 1300 can generate electromagnetic noise, which can cause the captured image to become blurred or the image quality to deteriorate, thereby reducing the electromagnetic compatibility (EMC) of the camera module.

[0162] To solve the above problem, it is necessary to ground the substrate part 1300 to eliminate or reduce static electricity generated in the substrate part 1300, and in this third embodiment, the second fence 1500 can serve as the ground part.

[0163] In order for the second fence 1500 to function as a grounding part, the base part 1300 and the second fence 500 must be electrically connected to each other, and such an electrical connection structure will be described in detail below with reference to the drawings.

[0164] 14, the second fence 1500 may be connected to the first fence 1400 by surrounding the first fence 1400 at the rear side of the first fence 1400. In this case, the second fence 1500 may be detachably connected to the first fence 1400.

[0165] The second fence 1500 may be formed with a hook 1520 that is detachably coupled to the first fence 1400. Furthermore, the first fence 1400 may be formed with a through-hole 1440 to which the hook 1520 is coupled at a position corresponding to the hook 1520.

[0166] Since the hook 1520 is elastically deformable, the hook 1520 is elastically deformed to be attached to or detached from the through-hole 1440, and thus the second fence 1500 can be detachably attached to the first fence 1400.

[0167] 15, the camera module of the embodiment may further include a finger 1600. The finger 1600 may serve to electrically connect the substrate unit 300 and the second fence 1500.

[0168] For example, the fingers 1600 may electrically connect the second fence 1500 and the third substrate 1313. The fingers 1600 may be coupled to the third substrate 1313, and the second fence 1500 may have a pressing portion 1510 formed at a position corresponding to the fingers 1600 to press the fingers 1600.

[0169] With this structure, when the pressure member 1510 presses the fingers 1600, the pressure member 1510 and the fingers 1600 come into contact with each other, thereby electrically contacting the second fence 1500 and the substrate unit 1300 including the third substrate 1313. The specific structures of the fingers 1600 and the pressure member 1510 will be described in detail below with reference to the drawings.

[0170] Meanwhile, the second fence 1500 is preferably formed of a conductive material, for example, a conductive metal material, so that it is electrically connected to the third substrate 1313 and static electricity generated in the substrate unit 1300 flows to the second fence 1500.

[0171] Figure 16 is a view of Figure 15 with the second fence 1500 of one embodiment removed. Figure 17 is a view of Figure 16 rotated around the z-axis. Figure 18 is a perspective view of the first fence 1400 of one embodiment.

[0172] The first fence 1400 may be coupled to the substrate portion 1300 to separate the plurality of printed circuit boards 1310 from each other in the optical axis direction, and may include a body coupling portion 1430, a first protrusion 1410, and a second protrusion 1420.

[0173] A body connector 1430 may be provided on one side, i.e., the front portion, of the first fencer to be connected to the front body 1200. In this case, the body connector 1430 may be disposed between the front body 1200 and the first board 1311 to connect the front body 1200 and the first board 1311.

[0174] At this time, the front body 1200, the body connecting part 1430, and the first board 1311 can be connected to each other by a fastening mechanism 1810 (see FIGS. 12 and 13). With this structure, the board part 1300 including the first board 1311 can be connected to the front body 1200 by the first fence 1400.

[0175] At this time, a through hole may be formed in the body coupling part 1430 as shown in FIG. 18 so that the image sensor 1700 mounted on the entire surface of the first substrate 1311 faces the lens part 1100.

[0176] The first protrusion 1410 may support one surface, such as the front surface, of the printed circuit board 1310. The second protrusion 1420 may support the other surface, such as the rear surface, of the printed circuit board 1310.

[0177] Therefore, the first protrusion 1410 and the second protrusion 1420 can be formed spaced apart in the optical axis direction, and this separation distance can correspond to the thickness of each printed circuit board 1310, i.e., the second board 1312 and the third board 1313.

[0178] The second substrate 1312 and the third substrate 1313 can be coupled to the first fence 1400 by the first protrusion 1410 and the second protrusion 1420 and arranged to be spaced apart in the optical axis direction.

[0179] That is, the second substrate 1312 and the third substrate 1313 can be sandwiched between the first protrusion 1410 and the second protrusion 1420 and connected to the first fence 1400. Meanwhile, the first substrate 1311 can be connected to the body connecting portion 1430 by the fastening mechanism 1810 as described above and not sandwiched between the first protrusion 1410 and the second protrusion 1420.

[0180] With this structure, in the first fence 1400 of this embodiment, the first protrusion 1410 and the second protrusion 1420 can be arranged at three positions spaced apart from each other in the optical axis direction. This is because, in this third embodiment, the second −1 substrate 1312-1, the second −2 substrate 1312-2, and the third substrate 1313 can be sandwiched between the first protrusion and the second protrusion 1420.

[0181] The optical axis direction separation positions between the first substrate 1311, the second -1 substrate 1312-1, the second -2 substrate 1312-2, and the third substrate 1313 can be determined by the optical axis direction separation positions of each of the first protrusion 1410 and the second protrusion 1420.

[0182] In this third embodiment, by using the first fence 1400 including the body connecting portion 1430, the first protrusion 1410 and the second protrusion 1420, it is possible to easily align the multiple printed circuit boards 1310 provided on the substrate portion 1300 of the camera module at set intervals in the optical axis direction.

[0183] Furthermore, the first fence 1400 is provided to surround the substrate unit 1300, thereby partially blocking electromagnetic waves generated from the substrate unit 300.

[0184] 19 is a partial perspective view showing portion A of FIG. 13. The finger 1600 may include a substrate coupling portion 1610 and an elastically deformable portion 1620. The substrate coupling portion 1610 may be coupled to the third substrate 1313. In this case, the substrate coupling portion 1610 and the third substrate 1313 may be coupled to each other by soldering, a conductive adhesive, etc. The elastically deformable portion 1620 extends from the substrate coupling portion 1610 and is elastically deformable.

[0185] The second fence 1500 may be electrically connected to the third substrate 1313 by pressing the elastic deformation portion 1620. In this case, the second fence 1500 may include a pressing portion 1510 that protrudes toward the substrate portion 1300 and presses the finger 1600.

[0186] When the pressure applying portion 1510 contacts the elastic deformation portion 1620 and applies pressure to the elastic deformation portion 1620, the elastic deformation portion 1620 undergoes elastic deformation. This structure allows the pressure applying portion 1510 and the elastic deformation portion 1620 to be electrically connected more reliably, thereby preventing electrical disconnection between the pressure applying portion 1510 and the elastic deformation portion 1620.

[0187] That is, when the second fence 1500 is connected to the first fence 1400, the end of the pressure member 1510 is located further below the upper surface of the elastic deformation member 1620, so that the elastic deformation member 1620 deforms and simultaneously makes secure contact with the pressure member 1510, thereby enabling the pressure member 1510 and the elastic member to be electrically connected more securely without electrical disconnection.

[0188] When the pressure member 1510 and the elastic deformation member 1620 are electrically connected, the second fence 1500 including the pressure member 1510, the finger 1600 including the elastic deformation member 1620, and the substrate member 1300 including the finger 1600 can be electrically connected.

[0189] Therefore, static electricity generated in the substrate part 1300 can flow to the electrically connected second fence 1500, and the second fence 1500 acts as a grounding part, thereby eliminating or significantly reducing static electricity generated in the substrate part 1300.

[0190] In this third embodiment, the substrate part 1300 and the second fence 1500 are electrically connected, and static electricity generated on the substrate part 1300 flows to the second fence 1500, which functions as a grounding part, thereby eliminating or significantly reducing static electricity generated on the substrate part 1300.

[0191] Also, by eliminating or significantly reducing static electricity generated in the substrate unit 1300, it is possible to prevent degradation of image quality of the camera module and degradation of electromagnetic compatibility (EMC) due to static electricity.

[0192] Figure 20 is a perspective view showing third substrate 1313 and fingers 1600 of the third embodiment. Figure 21 is a side view showing fingers 1600 of one embodiment.

[0193] 20, the finger 1600 may be coupled to the rear surface of the third board 1313, which is disposed at the rear end of the printed circuit board 1310. The finger 1600 may be provided at a position facing the pressure portion 1510 formed on the second fence 1500 in the optical axis direction.

[0194] Also, the number of fingers 1600 may be the same as the number of pressure members 1510. Although two fingers 1600 are provided in Fig. 20, the number is not limited thereto, and one, three or more fingers 1600 may be provided.

[0195] In addition, the position of the fingers 1600 is not particularly limited, and the position and number of the fingers 1600 can be appropriately selected in consideration of the detailed structure or the overall structure of the camera module. In this case, the pressing unit 1510 can be provided to correspond to the position and number of the fingers 1600.

[0196] 21, the elastic deformation portion 1620 of the finger 1600 may be provided with an overall S-shape in a side view. However, this is only one example, and the elastic deformation portion 1620 may be in any shape as long as the elastic deformation portion 1620 is elastically deformed by the pressure portion 1510 and can reliably maintain mechanical and electrical contact between the elastic deformation portion 1620 and the pressure portion 1510.

[0197] Meanwhile, it is appropriate that the fingers 1600 are formed of a material having excellent wear resistance, fatigue strength, elastic limit, electrical conductivity, etc. Therefore, the fingers 1600 may be made of, for example, beryllium copper.

[0198] Although several embodiments have been described above, various other implementations are possible. The technical contents of the above-described embodiments can be combined in various ways, as long as they are not mutually incompatible, and thus can be embodied in new embodiments.
