Mode for Carrying Out the Invention

[0009] Hereinafter, in order to explain the present disclosure in more detail, embodiments for carrying out the present disclosure will be described with reference to the accompanying drawings. Embodiment 1. FIG. 1 is a perspective view of a camera module 1 according to the present disclosure. FIG. 2 is a diagram showing the camera module 1 as seen in the direction of arrow A in FIG. 1. FIG. 3 is a partial cross-sectional view of the camera module 1 as seen along the line B-B in FIG. 2. The camera module 1 is an imaging device that images an object and outputs the captured image as image data. Further, the camera module 1 is a so-called camera module with a pigtail cable, and outputs image data to an external device (not shown).

[0010] The camera module 1 shown in FIG. 1 includes a housing 10, an electronic board 20, a connector 30, a cable 40, an external device connection connector 50, a first cable positioning part 60, and a second cable positioning part 70.

[0011] The housing 10 is, for example, box-shaped and has a space inside surrounded by the wall portion 12. The housing 10 has an inner wall surface 12a and an outer wall surface 12b. In FIG. 1, the upper part of the housing 10 of the camera module 1 is open, but the housing 10 includes a lid portion (not shown) for covering the upper part. The housing 10 also has an opening portion 14 in which an opening 13 is formed that penetrates between the inner wall surface 12a and the outer wall surface 12b. The opening 13 is a space for arranging the cable 40 and has the same width as the width of the cable 40. The lid portion (not shown) of the housing 10 is provided with, for example, a lens (not shown) and is configured to take in external light into the housing 10 through the lens. Note that the lens may be provided on the wall portion 12 other than the lid portion in the housing 10.

[0012] Inside the housing 10, a board positioning portion 11 is provided. The board positioning portion 11 is configured to fix the position of the electronic board 20 disposed inside the housing 10 within the housing 10. The board positioning portions 11 shown in FIGS. 1, 2, and 3 are L-shaped and are disposed at the four corners of the electronic board 20. Although not shown, the board positioning portion 11 is configured to position the electronic board 20 also from the direction of the lid portion.

[0013] The electronic board 20 is disposed inside the housing 10 and mounts components such as an imaging element, a circuit, and a connector 30 for causing the camera module 1 to function as an imaging device. Note that the imaging element and the circuit may be an imaging element and a circuit that utilize existing technologies for causing the imaging device to function, and are not shown in the present disclosure. The imaging element images the range of the imaging target and outputs image data by imaging.

[0014] The connector 30 is mounted on the electronic substrate 20 inside the housing 10, is connected to the imaging element via a circuit on the electronic substrate 20, and is connected to the external device connection connector 50 via the cable 40. The connector 30 according to the present disclosure does not have a locking mechanism for preventing the cable 40 from coming off. Accordingly, it is configured not to increase the mounting area on the electronic substrate 20.

[0015] The cable 40 is disposed so as to pass through the opening 13 in the housing 10. One end of the cable 40 is connected to the connector 30 inside the housing 10, and the other end of the cable 40 is connected to the external device connection connector 50. The cable 40 receives image data from the imaging element via the circuit and the connector 30, and sends the image data to the external device connection connector 50. Note that the cable 40 shown in each figure has a circular cross section, but the present disclosure is not limited to a cable having a circular cross section.

[0016] The external device connection connector 50 is a connector for connecting to an external device such as an image processing apparatus. The external device connection connector 50 is connected to the other end of the cable 40. The cable 40 having the external device connection connector 50 is a so-called pigtail cable.

[0017] The first cable positioning portion 60 covers the outer periphery of the cable 40 inside the housing 10, has a width larger than the width of the opening 13, and contacts the inner wall surface 12a of the housing 10.

[0018] The second cable positioning portion 70 covers the outer periphery of the cable 40 outside the housing 10, has a width larger than the width of the opening 13, and contacts the outer wall surface 12b of the housing 10.

[0019] The first cable positioning portion 60 and the second cable positioning portion 70 are each fixed in a state of being attached to the cable 40 so as to sandwich the cable 40 and prevent it from moving in the extending direction of the cable 40. Specifically, the portions of the first cable positioning portion 60 and the second cable positioning portion 70 that contact the outer periphery of the cable 40 are configured to apply a slight pressure to the cable 40. For example, the portions of each cable positioning portion that contact the outer periphery of the cable 40 are formed with a plurality of small protrusions. Also, the first cable positioning portion 60 and the second cable positioning portion 70 are disposed opposite to each other with the opening 14 in the housing 10 therebetween. The first cable positioning portion 60 positions the cable 40 so as not to move in the direction in which the cable 40 is pulled out from the housing 10 of the camera module 1. The second cable positioning portion 70 positions the cable 40 so as not to move in the direction in which the cable 40 is pushed into the housing 10 of the camera module 1. Thereby, in the camera module 1, when suppressing the cable 40 from coming off the connector 30, it is not necessary to provide a locking mechanism for the connector 30, and the area of the substrate can be reduced.

[0020] Here, in the camera module, in order to reduce noise during high-speed transmission of an image from the camera module to an external device, a noise filter may conventionally be mounted on the substrate. In this case, similar to the case where a locking mechanism is provided for the connector, it becomes difficult to reduce the area of the substrate. In contrast, the first cable positioning portion 60 according to the present disclosure is configured to include a noise removal member. Similarly, the second cable positioning portion 70 according to the present disclosure is configured to include a noise removal member. This configuration can prevent the cable 40 from coming off the connector 30 on the electronic substrate 20 as described above even when continuously receiving vibrations during vehicle travel, particularly when the camera module 1 is an in-vehicle camera module for mounting on a vehicle, and can reduce noise. Thus, it contributes to making the camera module 1 implementing these functions smaller. When configured to include a noise removal member, the first cable positioning portion 60 and the second cable positioning portion 70 are configured to cover the surface of the cable 40 in a direction perpendicular to the length direction of the cable 40 in a circular manner. The noise removal member of the first cable positioning portion 60 and the noise removal member of the second cable positioning portion 70 are formed using, for example, ferrite. Alternatively, the noise removal member of the first cable positioning portion 60 and the noise removal member of the second cable positioning portion 70 are formed using, for example, a material obtained by mixing a magnetic material and a resin.

[0021] In the description, a configuration in which both the first cable positioning portion 60 and the second cable positioning portion 70 include a noise removal member is described. However, in the present disclosure, it is sufficient that at least one of the first cable positioning portion 60 or the second cable positioning portion 70 includes a noise removal member. Whether to provide the noise removal member in the first cable positioning portion 60, the second cable positioning portion 70, or both is appropriately designed according to the noise removal function required in the design. Thereby, when configuring the camera module to have a noise removal function, it is possible to obtain a small camera module without mounting a noise filter circuit or the like on the substrate, without increasing the number of components, and while reducing the area of the substrate.

[0022] The first cable positioning portion 60 or the second cable positioning portion 70 has a detachable structure from the cable 40. Specifically, the first cable positioning portion 60 or the second cable positioning portion 70 is composed of a plurality of divided portions divided in a direction perpendicular to the extending direction of the cable 40. In addition, the plurality of divided portions are combined around the cable and have a configuration capable of maintaining the combined state. With such a structure, the first cable positioning portion 60 or the second cable positioning portion 70 is configured to be detachable from the cable 40. A first form of the detachable structure in the cable positioning portion will be described below. Hereinafter, the second cable positioning portion 70 will be described as a representative example. In this description, the second cable positioning portion 70 is simply referred to as the cable positioning portion 70.

[0023] FIG. 4 is a diagram showing a first form of the detachable structure in the cable positioning portion 70 according to the present disclosure. FIG. 5 is a cross-sectional view showing a first form of the detachable structure in the cable positioning portion 70 according to the present disclosure. FIG. 6 is a diagram for explaining a detachment method in the case of the structure shown in FIGS. 4 and 5. In the plurality of divided portions 71, 72 constituting the cable positioning portion 70, a concave portion 72b is formed on the dividing surface 72a of one of the divided portions 72 facing each other, and a convex portion 71b is formed on the dividing surface 71a of the other divided portion 71. The concave portion 72b is formed on the dividing surface of one of the divided portions adjacent to each other among the plurality of divided portions. Further, the concave portion 72b is formed along the extending direction of the cable 40. Further, the concave portion 72b has a T-shaped cross section. The convex portion 71b is formed on the dividing surface of the other divided portion among the divided portions adjacent to each other in the plurality of divided portions. Further, the convex portion 71b is formed along the extending direction of the cable 40. Further, the concave portion 72b has a T-shaped cross section.

[0024] Specifically, the cable positioning portion 70 has, as a plurality of divided portions, for example, two divided portions 71 and 72 shown in FIGS. 4, 5, and 6. The two divided portions 71 and 72 are composed of a first divided portion 71 and a second divided portion 72. As shown in FIGS. 4, 5, and 6, the shapes of the first divided portion 71 and the second divided portion 72 are each a shape obtained by dividing a cylindrical shape approximately in half in the axial direction (in the present disclosure, the axial direction of the cable 40 is also referred to as the extending direction of the cable 40).

[0025] In the first divided portion 71, a convex portion 71b protruding with respect to the dividing surface 71a is formed on the dividing surface 71a of the first divided portion 71. The convex portion 71b of the first divided portion is formed so as to be continuous along the extending direction of the cable 40. The convex portion 71b of the first divided portion has a T-shaped cross section in which the width at the position farthest from the width at the position of the dividing surface 71a in the cross section is large.

[0026] In the second divided portion 72, a concave portion 72b dug down with respect to the dividing surface 72a is formed on the dividing surface 72a of the second divided portion 72. The concave portion 72b of the second divided portion is formed so as to be continuous along the extending direction of the cable 40. The concave portion 72b of the second divided portion has a T-shaped cross section in which the width at the position farthest from the width at the position of the dividing surface 72a in the cross section is large.

[0027] The T-shaped cross section of the convex portion 71b in the first divided portion 71 and the T-shaped cross section of the concave portion 72b in the second divided portion 72 correspond to each other and are formed so as to fit into each other. A method of attaching this cable positioning portion 70 to the cable 40 will be described below.

[0028] First, the first divided portion 71 and the second divided portion 72 are arranged so as to contact the cable 40 at different positions from each other. Next, when the position of the convex portion 71b of the first divided portion 71 coincides with the position of the concave portion 72b of the second divided portion 72, and at least one of the first divided portion 71 or the second divided portion 72 is slid in the extending direction of the cable 40, the convex portion 71b of the first divided portion 71 and the concave portion 72b of the second divided portion 72 fit together as they are slid. In this way, by the complete fitting of the first divided portion 71 and the second divided portion 72, the cable positioning portion 70 is attached to the cable 40.

[0029] In the description, the convex portion 71b of the first divided portion 71 and the concave portion 72b of the second divided portion 72 are described as having a T-shaped cross section respectively, but the convex and concave portions in the present disclosure are not limited to this. The convex and concave portions in the present disclosure may have any shape as long as they can form the first cable positioning portion 60 or the second cable positioning portion 70 attached to the cable 40 by the above attachment method. For example, the convex and concave portions may each have a wedge shape or a substantially V shape in which the width in their cross section increases as it moves away from the position of the dividing surface.

[0030] Also, in the description, the first divided portion 71 is shown as having only the convex portion 71b formed, and the second divided portion 72 is shown as having only the concave portion 72b formed, but the first divided portion 71 and the second divided portion 72 may each have a convex portion and a concave portion formed therein. In this case, the first divided portion 71 and the second divided portion 72 can be made of the same part, and the number of types of parts can be reduced.

[0031] As described above, the camera module according to the present disclosure includes a housing having an inner wall surface and an outer wall surface, the housing having an opening portion formed therethrough between the inner wall surface and the outer wall surface, an electronic substrate disposed inside the housing, a connector mounted on the electronic substrate, a cable disposed to pass through the opening and connected to the connector, a first cable positioning portion covering an outer periphery of the cable inside the housing and having a width larger than a width of the opening and contacting the inner wall surface of the housing, and a second cable positioning portion covering an outer periphery of the cable outside the housing and having a width larger than the width of the opening and contacting the outer wall surface of the housing. The first cable positioning portion and the second cable positioning portion are disposed opposite to each other with the opening portion therebetween, and at least one of the first cable positioning portion or the second cable positioning portion has a noise removing member. As a result, in the camera module, there is an effect that a camera module capable of further reducing the area of the substrate can be provided.

[0032] The camera module according to the present disclosure is further configured such that the first cable positioning portion or the second cable positioning portion has a structure detachable from the cable. As a result, there is an effect that a camera module in which the number of cable positioning portions attached to the cable can be easily changed as required according to the specifications can be provided.

[0033] The camera module according to the present disclosure is further configured such that the first cable positioning portion or the second cable positioning portion is composed of a plurality of divided portions divided in a direction perpendicular to an extending direction of the cable. As a result, there is an effect that a camera module including a cable positioning portion composed of a plurality of divided portions can be provided.

[0034] The camera module according to the present disclosure further has the plurality of divided parts, wherein a concave part having a T-shaped cross section is formed along the extension direction of the cable on the dividing surface of one of the divided parts adjacent to each other, and a convex part having a T-shaped cross section is formed along the extension direction of the cable on the dividing surface of the other of the divided parts adjacent to each other. Accordingly, it is possible to provide a camera module including a cable positioning part in which a plurality of divided parts are slid and attached to the cable in the extension direction of the cable. This has the effect of

Accordingly, it is possible to provide a camera module including a cable positioning part using ferrite as a noise removing member, which has the effect of

[0036] The camera module according to the present disclosure further has the first cable positioning part or the second cable positioning part formed using a material obtained by mixing a magnetic material and resin. Accordingly, it is possible to provide a camera module including a cable positioning part using a material obtained by mixing a magnetic material and resin as a noise removing member, which has the effect of

[0037] The camera module according to the present disclosure is further configured as an in-vehicle camera module for mounting on a vehicle. Accordingly, it is possible to provide an in-vehicle camera module with further reduced size, which has the effect of

[0038] Embodiment 2. Embodiment 2 is a camera module in which the detachable structure in the cable positioning part is in a second form. The camera module of Embodiment 2 is the same as the camera module of Embodiment 1, except that the detachable structure in the cable positioning portion is different. Therefore, in the description, the detachable structure in the cable positioning portion will be described, and the description of the same configuration as the camera module of Embodiment 1 will be omitted as appropriate. The detachable structure in the cable positioning portion according to Embodiment 2 will be described with reference to FIGS. 7, 8, and 9. Hereinafter, in the description of Embodiment 2, the first cable positioning portion 60 and the second cable positioning portion 70 will be simply referred to as the cable positioning portion, unless otherwise described separately.

[0039] FIG. 7 is a diagram showing a second form of the detachable structure in the cable positioning portion 70 according to the present disclosure. FIG. 8 is a cross-sectional view for explaining the second form of the detachable structure in the cable positioning portion 70 according to the present disclosure. FIG. 9 is a diagram for explaining the attaching / detaching method in the case of the structure shown in FIGS. 7 and 8. In the plurality of divided portions 73 constituting the cable positioning portion 70, concave portions 73d are formed on the dividing surface 73c, and convex portions 73b are formed on the dividing surface 73a. The concave portion 73d is formed by being dug down with respect to the dividing surface 73c on the dividing surface 73c of one of the adjacent divided portions 73 among the plurality of divided portions 73. Further, the concave portion 73d is formed along the extension direction of the cable 40. The convex portion 73b is formed so as to protrude with respect to the dividing surface 73a on the dividing surface 73a of the other of the adjacent divided portions 73 among the plurality of divided portions 73. Further, the convex portion 73b is formed along the extension direction of the cable 40. The concave portion 73d and the convex portion 73b are formed to fit into each other. Also, for example, the width of the convex portion 73b is slightly larger than the width of the concave portion 73d, or the width of the concave portion 73d is slightly smaller than the width of the convex portion 73b.

[0040] Specifically, the cable positioning portion 70 has, as a plurality of divided portions, for example, two divided portions 73, 73 shown in FIGS. 7, 8, and 9. The two divided portions 73, 73 are composed of a first divided portion 73 and a second divided portion 73. The shapes of the first divided portion 73 and the second divided portion 73 shown in FIGS. 7, 8, and 9 are each a shape obtained by dividing a cylindrical shape approximately in half in the axial direction (in the present disclosure, the axial direction of the cable 40 is also referred to as the extending direction of the cable 40).

[0041] The divided portion 73 has a convex portion 73b protruding with respect to the dividing surface 73a on the dividing surface 73a with an adjacent other divided portion 73. The convex portion 73b of the divided portion 73 is formed so as to be continuous along the extending direction of the cable 40. The divided portion 73 has a concave portion 73d dug down with respect to the dividing surface 73c on the dividing surface 73c with an adjacent other divided portion 73. The concave portion 73d of the divided portion 73 is formed so as to be continuous along the extending direction of the cable 40.

[0042] The shape of the convex portion 73b in the divided portion 73 and the shape of the concave portion 73d in an adjacent other divided portion 73 correspond to each other and are formed so as to fit into each other. Further, the shape of the convex portion 73b in the divided portion 73 and the shape of the concave portion 73d in an adjacent other divided portion 73 are configured so as not to be easily detached in the fitted state. For example, the width of the convex portion 73b is formed to be slightly larger than the width of the concave portion 73d, or the width of the concave portion 73d is formed to be slightly smaller than the width of the convex portion 73b. A method of attaching this cable positioning portion 70 to the cable 40 will be described below.

[0043] First, the first divided portion 73 and the second divided portion 73 are arranged at positions facing each other via the cable 40. Next, the convex portion 73b of the first divided portion 73 and the concave portion 73d of the second divided portion 73 are aligned and pressed, so that the convex portion 73b and the concave portion 73d are fitted together. In this way, by the convex portion 73b and the concave portion 73d in the first divided portion 73 and the second divided portion 73 adjacent to each other fitting together completely, the cable positioning portion 70 is attached to the cable 40.

[0044] The camera module according to the present disclosure further has a concave portion formed on the dividing surface of one of the divided portions adjacent to each other among the plurality of divided portions, and the concave portion fitting with the concave portion (having a width larger than the width of the concave portion) is formed on the dividing surface of the other of the divided portions adjacent to each other. It is configured as described above. As a result, it is possible to provide a camera module provided with a cable positioning portion in which a plurality of divided portions are attached so as to sandwich the cable with respect to the cable.

[0045] Embodiment 3. Embodiment 3 is a camera module in which the detachable structure in the cable positioning portion is in a third form. The camera module of Embodiment 3 is different from the camera module of Embodiment 1 in the detachable structure in the cable positioning portion, and is otherwise the same as the camera module of Embodiment 1. Therefore, in the description, the detachable structure in the cable positioning portion will be described, and the description of the same configuration as the camera module of Embodiment 1 will be omitted as appropriate. The detachable structure in the cable positioning portion according to Embodiment 3 will be described with reference to FIGS. 10A and 10B.

[0046] FIGS. 10A and 10B are diagrams for explaining a third form of the detachable structure in the cable positioning portion according to the present disclosure. The first cable positioning portion 60 or the second cable positioning portion 70 includes a fixture 75 for bundling a plurality of divided portions 74 on the outer periphery of the first cable positioning portion 60 or the second cable positioning portion 70. The fixture shown in FIGS. 10A and 10B has, for example, the same length as the length of the first cable positioning portion 60 or a slightly shorter length, and is made of an elastic material. The fixture shown in FIGS. 10A and 10B has, for example, the same length as the length of the second cable positioning portion 70 or a slightly shorter length, and is made of an elastic material.

[0047] The cable positioning portion has, as a plurality of divided portions, for example, two divided portions 74 shown in FIG. 10A. The two divided portions 74 are a first divided portion 74 and a second divided portion 74 adjacent to the first divided portion 74. The shapes of the first divided portion 74 and the second divided portion 74 shown in FIG. 10A are each a shape obtained by dividing a cylindrical shape approximately in half in the axial direction (in the present disclosure, the axial direction of the cable 40 is also referred to as the extending direction of the cable 40). A method of attaching this cable positioning portion to a cable will be described below.

[0048] First, pass the fixture 75 through the cable 40. Next, the first divided portion 74 and the second divided portion 74 are arranged at positions facing each other with the cable 40 interposed therebetween. Next, while slightly expanding the fixture 75, shift it to a position covering the first divided portion 74 and the second divided portion 74. The fixture 75 fixes the divided surface of the first divided portion 74 and the divided surface of the second divided portion 74 so as to be in close contact with each other. In this way, the cable positioning portion is attached to the cable 40.

[0049] The camera module according to the present disclosure is further configured such that the first cable positioning portion or the second cable positioning portion includes a fixture for bundling a plurality of divided portions on the outer periphery of the first cable positioning portion or the second cable positioning portion. As a result, there is an effect that the shape of a plurality of divided portions in the cable module can be simplified.

[0050] Embodiment 4. Embodiment 4 is a form in which the first cable positioning portion or the second cable positioning portion is composed of a ferrite core and resin. The camera module of Embodiment 4 is different from the camera module of Embodiment 1 in the configuration of the cable positioning portion, and is otherwise the same as the camera module of Embodiment 1. In the description, the configuration of the cable positioning portion will be described, and the description of the same configuration as that of the camera module of Embodiment 1 will be omitted as appropriate. The camera module according to Embodiment 4 will be described with reference to FIG. 11.

[0051] FIG. 11 is a partial cross-sectional view of the camera module 1A taken along line B-B in FIG. 2 when the cable positioning portion is coated with resin 60b. The camera module 1A shown in FIG. 11 includes a housing 10, an electronic substrate 20, a connector 30, a cable 40, an external device connection connector 50, a first cable positioning portion 60A, and a second cable positioning portion 70A. The housing 10, the electronic substrate 20, the connector 30, the cable 40, and the external device connection connector 50 are the same as the configurations described in other embodiments, and the description thereof will be omitted.

[0052] In the camera module 1A shown in FIG. 11, the first cable positioning portion 60A is composed of a ferrite core 60a and a resin 60b that covers the ferrite core 60a. In the camera module 1A shown in FIG. 11, the second cable positioning portion 70A is composed of a ferrite core 70a and a resin 70b that covers the ferrite core 70a.

[0053] The ferrite core 60a constitutes a plurality of divided portions. The plurality of divided portions are, for example, the plurality of divided portions 73 shown in FIGS. 7, 8, and 9, or the plurality of divided portions 74 shown in FIG. 10A. The resin 60b that covers the ferrite core 60a is connected, for example, at one end of adjacent divided portions among the plurality of divided portions. In other words, the resin 60b that covers the ferrite core 60a integrates the plurality of divided portions. Further, the resin 60b that covers the ferrite core 60a has fitting portions at both ends.
