[0045] Hereinafter, a description will be provided by assuming that the ±X direction illustrated in each drawing is the front-rear direction, the ±Y direction is the width direction, and the ±Z direction is the up-down direction.
Camera Module 10

[0047] The camera module 10 is configured to be connectable to an external connector (not illustrated) constituting a “first connection object” of a connecting portion 10a (see
First Component 11
[0048] A first component 11 includes a first housing 20, an imaging unit 30, and an internal connector 70.
[0049] The first housing 20 is formed of an insulator such as synthetic resin, for example. The first housing 20 has a peripheral wall 20a, a bottom wall 20b, and a lens arrangement portion 20c. The peripheral wall 20a has a substantially square cylinder shape. The lens arrangement portion 20c has a cylinder shape. The bottom wall 20b is formed so as to connect the lower ends of the peripheral wall 20a and the lens arrangement portion 20c.
[0050] The imaging unit 30 includes an internal substrate 31, an imaging element 32, a lens 33, and a retainer 34. The internal substrate 31 is fixed to the first housing 20. The imaging element 32 is disposed on the lower surface of the internal substrate 31. The lens 33 is attached to the internal substrate 31 via the retainer 34 and is disposed on the inside of the lens arrangement portion 20c of the first housing 20.
[0051] The internal connector 70 is attached to the upper surface of the internal substrate 31. As illustrated in
Second Component 12
[0052] The second component 12 includes a second housing 40 constituting a “housing”, a coaxial connector portion 50, and an internal shell 60.
[0053] (Second Housing 40)
[0054] The second housing 40 forms a storage space 15 (see
[0055] The case body 41 is a part that forms the storage space 15 together with the first housing 20.
[0056] The case body 41 has a top wall 41a constituting an upper wall of the storage space 15, and a peripheral wall 41b constituting a wall of the storage space 15 in a direction perpendicular to the up-down direction. As illustrated in
[0057] The external connecting portion 42 is a part that protrudes upward from the top wall 41a of the case body 41, and is configured such that an external connector can be fitted thereto.
[0058] The second housing 40 is configured such that same can be arranged in a state where the coaxial connector portion 50 passes through in the up-down direction. In other words, the second housing 40 has an arrangement hole 40a (see
[0059] The case body 41 has a fitting portion 41c that fits into a fitted portion 20d (see
[0060] The second housing 40 has a holding portion 43 that holds the internal shell 60. As illustrated in
[0061] A plurality of (four) holding portions 43 are formed. Specifically, the ceiling surface 41d of the second housing 40 is formed having a substantially rectangular shape, and four holding portions 43 are formed in positions corresponding to the four corners of the substantially rectangular ceiling surface 41d.
[0062] (Coaxial Connector Portion 50)
[0063] The coaxial connector portion 50 is a part for electrically connecting an external connector and the internal connector 70. As illustrated in
[0064] The inner conductor 51 is a pin-shaped terminal and extends along the up-down direction (first direction).
[0065] The inner conductor 51 electrically connects a signal terminal of an external connector (not illustrated, first connection object) outside the storage space 15 to a signal terminal 71 of an internal connector 70 (second connection object) inside the storage space 15. The inner conductor 51 has, near its lower end, an enlarged-diameter portion 51a. The enlarged-diameter portion 51a has a cylinder shape.
[0066] The outer conductor 52 has a cylindrical shape and covers the inner conductor 51 from a direction perpendicular to the up-down direction (first direction). The outer conductor 52 is formed by casting or cutting. The vicinity of the upper end of the outer conductor 52 makes contact with the ground terminal of the external connector, and the lower end surface of the outer conductor 52 (an outer conductor contact portion 52b1) makes contact with the ground terminal 72 of the internal connector 70.
[0067] The outer conductor 52 has an upper portion 52a and a lower portion 52b. The lower portion 52b has an outer diameter larger than that of the upper portion 52a. A press-fitting protrusion, which is press-fitted into the second housing 40, is formed on the outer peripheral surface of the lower portion 52b.
[0068] The outer conductor 52 has a shell contact portion 52b2 that makes contact with the internal shell 60. The shell contact portion 52b2 is formed at the lower end of the outer peripheral surface of the lower portion 52b of the outer conductor 52.
[0069] The intermediate insulator 53 has a cylindrical shape and is disposed between the inner conductor 51 and the outer conductor 52. The intermediate insulator 53 functions to hold the inner conductor 51 with respect to the outer conductor 52. The intermediate insulator 53 is press-fitted into the cylindrical outer conductor 52. The inner conductor 51 is press-fitted into the cylindrical intermediate insulator 53 from below.
[0070] As illustrated in
[0071] The lower end surface of the outer conductor 52 serves as the outer conductor contact portion 52b1, which makes contact with the ground terminal 72 of the internal connector 70. The outer conductor contact portion 52b1 is a plane which has its normal oriented in the -Z direction, and extends circumferentially so as to surround the inner conductor contact portion 51a1.
[0072] As illustrated in
[0073] That is, the outer conductor contact portion 52b1 of the outer conductor 52, the inner conductor contact portion 51a1 of the inner conductor 51, and the lower surface 541 of the inner sealing portion 54 are formed on the same plane which has its normal oriented in the -Z direction. As a result, the contact portions 51a1, 541 and 52b1 of the coaxial connector portion 50 are formed in a planar shape.
[0074] A gap is formed between the outer conductor 52 and the ceiling surface 41d of the second housing 40. The outer sealing portion 55 is formed, by potting, in this gap. A lower surface 551 of the outer sealing portion 55 is formed on the same plane as the ceiling surface 41d of the second housing 40.
[0075]
[0076] When the second component 12 is attached to the first component 11, the coaxial connector portion 50 of the second component 12 makes contact with the signal terminal 71 and the ground terminal 72 of the internal connector 70 from above. As a result, the signal terminal 71 is elastically deformed, and the ground terminal 72 is elastically displaced downward.
[0077] (Internal Shell 60)
[0078] The internal shell 60 is disposed inside the storage space 15. The internal shell 60 is formed of a conductive material. Specifically, the internal shell 60 is formed by performing punching, bending, and the like on a conductive plate material.
[0079] As illustrated in
[0080] The top plate portion 61 has an opening 61a formed therein. The coaxial connector portion 50 passes through the opening 61a. Accordingly, the contact portions 51a1, 541 and 52b1 of the coaxial connector portion 50 are positioned below the top plate portion 61.
[0081] As illustrated in
[0082] (Spring Piece 62)
[0083] The internal shell 60 has four spring pieces 62 that make elastic contact with the outer conductor 52. The four spring pieces 62 make elastic contact with the outer conductor 52, whereby the internal shell 60 and the outer conductor 52 are electrically connected.
[0084] Each of the four spring pieces 62 has the same structure. Each of the four spring pieces 62 has a contact portion 62a that makes contact with the outer conductor 52, and an elastic support portion 62b that elastically supports the contact portion 62a. The elastic support portion 62b is positioned on the same plane as the top plate portion 61 in a free state. The width of the elastic support portion 62b gradually decreases toward the distal end side. The contact portion 62a is formed by bending the distal end side of the elastic support portion 62b downward.
[0085] As illustrated in
[0086] The four spring pieces 62 are configured from a front spring piece 62, a rear spring piece 62, a right spring piece 62, and a left spring piece 62.
[0087] The elastic support portion 62b of the front spring piece 62 extends toward the center of the opening 61a when taking, as the proximal end, a front position with respect to the center of the opening 61a.
[0088] The elastic support portion 62b of the rear spring piece 62 extends toward the center of the opening 61a when taking, as the proximal end, a rear position with respect to the center of the opening 61a.
[0089] The elastic support portion 62b of the right spring piece 62 extends toward the center of the opening 61a when taking, as the proximal end, a right position with respect to the center of the opening 61a.
[0090] The elastic support portion 62b of the left spring piece 62 extends toward the center of the opening 61a when taking, as the proximal end, a left position with respect to the center of the opening 61a.
[0091] That is, the four elastic support portions 62b of the four spring pieces 62 extend toward the outer conductor 52 from four positions in directions perpendicular to the up-down direction (first direction), and in a mutually perpendicular direction, with respect to the outer conductor 52.

[0093] The two-dot chain line C1 in
[0094] (Side Plate Portion 64)
[0095] As illustrated in
[0096] The side plate portion 64 is formed by bending the edge of the top plate portion 61 downward. Specifically, the side plate portion 64 is configured from four flat plate portions 65, namely, a front plate portion 65A, a rear plate portion 65B, a right plate portion 65C, and a left plate portion 65D. The lower ends of the four flat plate portions 65 constituting the side plate portion 64 are positioned below the lower end of the second housing 40 (see
[0097] The internal shell 60 has a held portion 66 that is held by the second housing 40.
[0098] Specifically, the held portion 66 is a press-fitting protrusion 66 that is formed on the flat plate portion 65 constituting the side plate portion 64. The press-fitting protrusion 66 constituting the held portion 66 is press-fitted into the press-fitting groove 43a (see
[0099] More specifically, the press-fitting protrusion 66 is formed on the front plate portion 65A and the rear plate portion 65B, and a press-fitting protrusion is not formed on the right plate portion 65C or the left plate portion 65D. The press-fitting protrusion 66 is formed at the plate ends, on both sides in the plate width direction (left-right direction), of the front plate portion 65A and the rear plate portion 65B. Positions where the press-fitting protrusion 66 is formed are the upper portions of the plate ends of the front plate portion 65A and the rear plate portion 65B in the plate width direction (both right and left sides), and the press-fitting protrusion 66 is not formed at the lower portions of these plate ends.
[0100] As illustrated in
Actions and Effects
[0101] Next, the actions and effects of the present embodiment will be described.
[0102] In the present embodiment, the second component 12 constituting an “electronic component” includes the second housing 40, the inner conductor 51, the outer conductor 52, and the internal shell 60. The second housing 40 forms the storage space 15 together with the first housing 20 by being attached to the first housing 20. The inner conductor 51 extends along the up-down direction and electrically connects an external connector (the first connection object) outside the storage space 15 to the internal connector 70 inside the storage space 15. The outer conductor 52 has a cylindrical shape and annularly surrounds the inner conductor 51 and extends in the first direction. The internal shell 60 is disposed inside the storage space 15 and electrically connected to the outer conductor 52.
[0103] Here, the internal shell 60 has the spring piece 62 that makes elastic contact with the outer conductor 52. Therefore, it is possible to ensure a favorable electrical connection between the internal shell 60 and the outer conductor 52 without joining the internal shell 60 and the outer conductor 52.
[0104] Furthermore, in the present embodiment, the spring piece 62 has the contact portion 62a that makes contact with the outer conductor 52, and the elastic support portion 62b that supports the contact portion 62a.
[0105] Here, the elastic support portion 62b extends in a direction perpendicular to the up-down direction. Therefore, it is possible to ensure, for the elastic support portion 62b, a spring length necessary for displacement of the contact portion 62a without increasing the size of the internal shell 60 in the up-down direction.
[0106] Here, in the present embodiment, the internal shell 60 has four spring pieces 62. Further, the four elastic support portions 62b of the four spring pieces 62 extend toward the outer conductor 52 from four positions in directions perpendicular to the up-down direction, and in mutually perpendicular directions, with respect to the outer conductor 52.
[0107] Therefore, a favorable electrical connection between the internal shell 60 and the outer conductor 52 can be more reliably ensured.
[0108] Further, in the present embodiment, the contact portion 62a is formed by bending the distal end side of the elastic support portion 62b inward in the first direction (toward the second connection object in the first direction). Therefore, it is easy to attach the internal shell 60 to the outer conductor 52 from the inside in the first direction.
[0109] Further, in the present embodiment, the internal shell 60 has the top plate portion 61 along a plane perpendicular to the up-down direction. Furthermore, the spring piece 62 includes the contact portion 62a that makes contact with the outer conductor 52, and the elastic support portion 62b that supports the contact portion 62a.
[0110] Here, the elastic support portion 62b extends from the top plate portion 61 in a direction perpendicular to the up-down direction. Therefore, the top plate portion 61 and the elastic support portion 62b are located on substantially the same plane.
[0111] Accordingly, when the internal shell 60 has the top plate portion 61, the spring length necessary for displacement of the contact portion 62a can be ensured for the elastic support portion 62b without increasing the size of the internal shell 60 in the up-down direction.
[0112] Furthermore, in the present embodiment, the top plate portion 61 has the opening 61a formed therein through which the outer conductor 52 passes. Here, the contact portion 62a is formed by bending the distal end side of the elastic support portion 62b inward in the first direction. The contact portion 62a and the outer conductor 52 make contact, on the inside in the first direction, relative to the top plate portion 61.
[0113] Therefore, it is not necessary to secure a space for the contact portion 62a and the outer conductor 52 to make contact on the outside (upper side) in the first direction of the top plate portion 61, and the entire second component 12 can be downsized.
[0114] Further, in the present embodiment, the top plate portion 61 has the extension portion 61d that extends from the proximal end of the spring piece 62 toward the opening 61a so as to extend the shielding range.
[0115] Therefore, a wide range can be shielded by the internal shell 60.
[0116] Furthermore, in the present embodiment, the internal shell 60 has the held portion 66 that is held by the second housing 40.
[0117] Therefore, the internal shell 60 is appropriately held in comparison with an embodiment in which the internal shell 60 does not have the held portion 66.
[0118] Note that, because the internal shell 60 is held by the second housing 40, the position of the internal shell 60 is affected by the second housing 40, and the positional relationship between the internal shell 60 and the outer conductor 52 may deviate from the desired positional relationship. However, because the internal shell 60 has the spring piece 62, a favorable electrical connection between the internal shell 60 and the outer conductor 52 is ensured even when the positional relationship between the internal shell 60 and the outer conductor 52 deviates from the desired positional relationship.
[0119] Further, in the present embodiment, the internal shell 60 includes the top plate portion 61 along a plane perpendicular to the up-down direction, and the side plate portion 64 formed by bending an end portion of the top plate portion 61 inward in the first direction. Further, the held portion 66 is formed by forming, on the side plate portion 64, the press-fitting protrusion 66 that is press-fitted into the second housing 40.
[0120] Thus, the internal shell 60 can be held by the second housing 40 while suppressing increased complexity of the shape of the internal shell 60.
