Summary of the Invention

Problems to be Solved by the Invention

[0005] The shield portion of the plug described in Patent Document 1 has a cylindrical body with multiple extruded protrusions formed radially inward by press working so as to contact the outer circumferential surface of the annular recess at the cylindrical end of the first cylindrical shell. These multiple extruded protrusions are arranged at equal intervals in the circumferential direction to correspond to multiple bent pieces. The cylindrical body is in close contact with the outer surface of the cylindrical end, and the ends of the multiple bent pieces are in contact with the inner end surface on the opening side of the housing, thereby locking the shield member to the first cylindrical shell. In this way, the multiple bent pieces are in contact with the housing, and the cylindrical body including the multiple extruded protrusions is in contact with the outer surface of the cylindrical end, so that the housing, the first cylindrical shell, and the shield member are electrically connected in an engaged state. For example, when mounting electronic components such as such plugs in a vehicle, miniaturization and low profile are required from the viewpoint of mounting space in the vehicle and fuel efficiency (electricity consumption).

[0006] Therefore, there is a need for connectors that can be made smaller and have a lower profile. [Means for solving the problem]

[0007] One embodiment of the connector according to the present disclosure is a connector for which a coaxial cable is electrically connected, comprising: a conductive terminal member electrically connectable to the internal conductor of the coaxial cable; an insulating holder that inserts and supports the terminal member; a conductive cylindrical shell electrically connected to the external conductor of the coaxial cable and covering the outside of the holder; and a conductive shielding member that contacts the cylindrical shell to block external electromagnetic waves, wherein the shielding member has a cylindrical body portion positioned opposite the cylindrical shell and a plurality of bent pieces folded radially outward from one end of the cylindrical body portion, the cylindrical shell has a cylindrical body portion covering the holder and an annular flange portion positioned radially outward of the cylindrical body portion, the bent pieces have a cut-out portion at their tip, and the shielding member is held in place by the cylindrical shell by the cut-out portion engaging with the flange portion.

[0008] According to this embodiment, since the bent piece is folded back, the radial length of the shield member does not increase. Furthermore, since the folded tip of the bent piece has a cut-out portion, the axial length of the cylindrical body does not increase. In addition, the shield member can be held in the cylindrical shell by engaging the cut-out portion with the flange portion. In this way, a connector that can be made smaller and lower in profile has been realized.

[0009] In another embodiment of the connector according to the present disclosure, the flange portion of the cylindrical shell is connected to the cylindrical body portion via connecting portions, a plurality of which are arranged at equal intervals along the circumferential direction on the radially outer side of the cylindrical body portion, and the shielding member is electrically connected to the cylindrical shell by the bending piece contacting the connecting portions due to elastic deformation.

[0010] According to this embodiment, the cylindrical body can evenly hold the flange portion in the circumferential direction via the connecting portion, and can also ensure electrical connection between the shielding member and the cylindrical shell.

[0011] In another embodiment of the connector according to this disclosure, each of the plurality of bent pieces of the shielding member is positioned between adjacent connecting portions in the circumferential direction.

[0012] According to this embodiment, the radial length of the connector does not increase due to the attachment of the shielding member, thus preventing the connector from becoming larger. [Brief explanation of the drawing]

[0013] [Figure 1] This figure schematically shows the configuration of a camera unit including a connector according to this embodiment. [Figure 2] This is a vertical cross-sectional view showing the camera module's receptacle mated with the socket's connector. [Figure 3] This is a disassembled perspective view of the socket. [Figure 4] These are the front and top views of the connector. [Figure 5] This is a cross-sectional view taken along the VV line in Figure 4. [Modes for carrying out the invention]

[0014] The embodiments of the connector relating to this disclosure will be described in detail below with reference to the drawings. The embodiments described below are illustrative examples for illustrating the connector and do not limit the connector to these embodiments only. Therefore, the connector can be implemented in various forms without departing from its essence.

[0015] In this embodiment, the socket 100 equipped with the connector 60 is provided on a camera unit U (in-vehicle camera) mounted on a vehicle. The camera unit U can also be used for applications other than in vehicles, such as on bicycles or drones.

[0016] Figure 1 is a schematic diagram showing the configuration of a camera unit U including a connector 60 according to this embodiment. Figure 2 is a longitudinal cross-sectional view showing the state in which the receptacle 47 of the camera module 40 is mated with the connector 60 of the socket 100. Figure 3 is an exploded perspective view showing the socket 100 disassembled into its constituent parts. Figure 4 is a front view of the connector 60. Figure 5 is a cross-sectional view of the connector 60 of Figure 4 taken along the VV line. However, the left half of Figure 5 shows a cross-section passing through the cut-up portion 65d of the cylindrical shell 63, which will be described later, and the right half shows a cross-section passing through the connecting portion 63d of the cylindrical shell 63.

[0017] [Camera unit configuration] As shown in Figure 1, the camera unit U can be electrically connected to a monitoring device (not shown) or an in-vehicle ECU (Electronic Control Unit) via a coaxial cable L.

[0018] The coaxial cable L is a communication cable for transmitting high-frequency signals. The coaxial cable L is configured such that an inner conductor formed of a bundle of copper wires and an outer conductor formed of a mesh-like copper wire covering the periphery of the inner conductor are coaxially arranged with an insulator sandwiched therebetween. The outer conductor functions as a shield to prevent leakage of high-frequency signals and intrusion of radio waves from the outside. The coaxial cable L outputs the high-frequency signal output from the camera unit U to a monitor device or an in-vehicle ECU. Also, the coaxial cable L supplies power from the monitor device or the in-vehicle ECU to the camera unit U. A plug LC is connected to the tip of the coaxial cable L, and the coaxial cable L and the connector 60 of the socket 100 are electrically connected via the plug LC.

[0019] The camera unit U includes a camera case H, a camera module 40 housed in the camera case H, and a socket 100 connected to the camera module 40. The camera case H is made of a conductive metal. The posture in which the camera unit U is used is not particularly limited, but in the following description, the direction of viewing the camera module 40 from the socket 100 is defined as the X1 direction, the opposite direction is defined as the X2 direction, and the direction connecting the X1 direction and the X2 direction is defined as the axial direction X for explanation.

[0020] 〔Configuration of Camera Module〕 As shown in FIG. 1, the camera module 40 includes an optical system 41 including at least one lens for incident light of a subject, an imaging device 42 such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor) that outputs an electrical signal based on the light collected by the optical system 41, and a substrate 43 on which an electronic circuit for driving and controlling the imaging device 42 and processing the electrical signal output from the imaging device 42 is mounted. A receptacle 47 for outputting a high-frequency signal processed by the electronic circuit is mounted on the substrate 43. The receptacle 47 is included in the camera module 40.

[0021] As shown in FIG. 2, the receptacle 47 includes a first contact 47a, a ground contact 47b, and an insulating portion 47c. The first contact 47a transmits a high-frequency signal. The ground contact 47b is electrically connected to a ground wiring formed on the substrate 43. The ground wiring is a wiring at a ground potential. The insulating portion 47c electrically insulates between the first contact 47a and the ground contact 47b.

[0022] 〔Configuration of Connector〕 Next, the configuration of the connector 60 according to the present embodiment will be described with reference to FIGS. 2 to 5. As shown in FIGS. 2 and 3, the socket 100 includes a connector 60 and a housing 10. The housing 10 is made of an insulator such as resin, and has a bottomed rectangular cylindrical tubular body 14 and a cylindrical fitting portion 16 extending in the X2 direction from the bottom of the tubular body 14. The tubular body 14 has a rectangular cylindrical shape in a direction view along the axial direction X (hereinafter also referred to as a plan view). Hereinafter, an axis parallel to the axial direction X passing through the intersection of the diagonals of the rectangle of the tubular body 14 in the plan view is referred to as a central axis Y. Further, the end portion of the tubular body 14 in the X1 direction is referred to as an opening 14b, and the space connected to the opening 14b and partitioned by the tubular body 14 is referred to as an internal space 14a.

[0023] The end portion (bottom portion) in the X2 direction in the internal space 14a of the tubular body 14 of the housing 10 is a first bottom surface 14d. At the center of the first bottom surface 14d, a concave portion 14e that is recessed in a circular shape in the plan view in the X2 direction from the first bottom surface 14d is formed. The end portion (bottom portion) in the X2 direction of the concave portion 14e is a second bottom surface 14f. The fitting portion 16 is disposed in the X2 direction from the second bottom surface 14f. The internal space 14a of the tubular body 14, the concave portion 14e, and the internal space 16a of the fitting portion 16 are connected. In the internal space 16a of the fitting portion 16, an annular plate-shaped first support portion 16b protruding radially inward from the inner peripheral surface 16d of the fitting portion 16 is formed. The connector 60 is disposed inside the housing 10 so as to be coaxial with the central axis Y and penetrate the first support portion 16b across the internal space 14a of the tubular body 14 to the internal space 16a of the fitting portion 16.

[0024] As shown in Figures 2, 3, and 5, the connector 60 comprises a signal terminal 61 (an example of a terminal member), a holder 62, a cylindrical shell 63, a first bush 64, and a connecting member 65 (an example of a shielding member). The signal terminal 61 has a rod shape made of a conductive metal or the like, and is positioned along the axial direction X so as to be coaxial with the central axis Y of the housing 10. The end of the signal terminal 61 in the X1 direction is a first contact end 61a that can be electrically connected to the first contact 47a of the receptacle 47 of the camera module 40, and the end in the X2 direction is a second contact end 61b that can be electrically connected to the internal conductor of the coaxial cable L via a plug LC. The holder 62 is made of resin and is positioned on the outer circumferential surface of the signal terminal 61 in the middle of the axial direction X. It is formed by insert molding and is integrated with the signal terminal 61. That is, the signal terminal 61 is inserted into and supported by the holder 62. The holder 62 has a cylindrical shape with the signal terminal 61 passing through its center. A stopper 62a, which has a relatively larger outer diameter than other parts, is integrally formed near the end of the holder 62 in the X1 direction. The first bush 64 is made of an elastic material such as rubber and has an annular plate shape with a through hole formed in the center along the axial direction X through which the signal terminal 61 can be inserted. By arranging the first bush 64, it is possible to suppress the intrusion of moisture into the inside of the connector 60 from the second contact end 61b side of the signal terminal 61.

[0025] The cylindrical shell 63 is made of a conductive metal and is configured to be electrically connectable to the outer conductor of the coaxial cable L. The cylindrical shell 63 covers the outside of the holder 62. In other words, the holder 62 is inserted (fitted) into the cylindrical shell 63. The cylindrical shell 63 includes a substantially cylindrical cylindrical body portion 63a, an annular plate-shaped flange portion 63b positioned radially outward with respect to the central axis Y relative to the cylindrical body portion 63a, and a connecting portion 63d that connects the cylindrical body portion 63a and the flange portion 63b. The cylindrical body portion 63a and the flange portion 63b are not directly connected, but are connected via the connecting portion 63d. The cylindrical body portion 63a has a small diameter portion 63e to which a plug LC can be connected, and a large diameter portion 63f positioned on the X1 side relative to the small diameter portion 63e and having a larger diameter than the small diameter portion 63e. The length of the small-diameter portion 63e along the axial direction X is longer than the length of the large-diameter portion 63f along the axial direction X, and the boundary between the small-diameter portion 63e and the large-diameter portion 63f is near the end of the cylindrical main body portion 63a in the X1 direction. The boundary between the small-diameter portion 63e and the large-diameter portion 63f is stepped on both the outer and inner sides. Both the outer and inner surfaces 63j of the large-diameter portion 63f are inclined so that they gradually decrease in diameter as they move from the boundary with the small-diameter portion 63e toward the X1 direction (see Figure 5).

[0026] A plate-shaped second support portion 63c is formed radially inward from the inner circumferential surface of the small-diameter portion 63e of the cylindrical main body portion 63a, having a hole in the center through which a signal terminal 61 can be inserted. A first bush 64 is positioned on the X1 side relative to the second support portion 63c so as to be in contact with the second support portion 63c, and a holder 62 is positioned on the X1 side relative to the first bush 64. The outer diameter of the holder 62 is approximately the same as the outer diameter of the first bush 64. On the X2 side relative to the second support portion 63c, the second contact end 61b of the signal terminal 61 is exposed, passing through the second support portion 63c.

[0027] The connecting portion 63d, which connects the cylindrical body portion 63a and the flange portion 63b, extends radially outward from the X2 direction end of the outer circumferential surface of the large diameter portion 63f of the cylindrical body portion 63a, then bends 90 degrees in the X1 direction and extends, connecting at the extended end to the radially innermost part of the upper surface 63h, which is the X2 direction end surface of the flange portion 63b. Multiple connecting portions 63d (eight in this embodiment) are arranged at equal intervals along the circumferential direction of the large diameter portion 63f of the cylindrical body portion 63a. Note that the lower surface 63i, which is the X1 direction end surface of the flange portion 63b, is located slightly closer to the X1 direction than the X1 direction end surface 63g of the large diameter portion 63f (see Figure 5).

[0028] The connecting member 65 is made of an elastic conductive metal and is composed of an annular portion 65a (an example of a cylindrical body portion) formed from a metal plate, a first connecting portion 65b (an example of a bent piece), and a second connecting portion 65c. Multiple first connecting portions 65b are provided at equal intervals along the circumferential direction of the annular portion 65a so as to extend along the axial direction X from the end of the annular portion 65a on the X2 direction side (eight in this embodiment). Multiple second connecting portions 65c are provided at equal intervals along the circumferential direction of the annular portion 65a so as to extend along the axial direction X from the end of the annular portion 65a on the X1 direction (eight in this embodiment). In a plan view, each of the multiple first connecting portions 65b is positioned to overlap with each of the multiple second connecting portions 65c.

[0029] The annular portion 65a is positioned opposite the outer surface of the large-diameter portion 63f of the cylindrical main body portion 63a, with a small gap between them, and the metal plate surface of the annular portion 65a is parallel to the axial direction X. In other words, the annular portion 65a and the large-diameter portion 63f are not in contact. Each of the multiple first connecting portions 65b is folded back approximately 180 degrees radially outward from the end of the annular portion 65a on the X2 direction side. In other words, when viewed in a direction perpendicular to the central axis Y, i.e., along the radial direction, the first connecting portions 65b and the annular portion 65a overlap. At the tip of each of the multiple first connecting portions 65b, there is one cut-out portion 65d that is cut and bent outward radially with respect to the plate surface of the first connecting portion 65b at a slight inclination (for example, 5 to 20 degrees). In other words, eight cut-out portions 65d are formed in the connecting member 65, the same number as the first connecting portions 65b. The annular portion 65a and the large-diameter portion 63f may be configured to be in contact.

[0030] As shown in Figure 4, each of the first connecting portions 65b is positioned to fit snugly between adjacent connecting portions 63d in the circumferential direction of the cylindrical shell 63. The outermost diameter of the first connecting portions 65b, excluding the cut-and-bent portions 65d, is slightly smaller than the inner diameter of the flange portion 63b, and the outermost diameter of the cut-and-bent portions 65d is slightly larger than the inner diameter of the flange portion 63b. The cut-and-bent portions 65d lock the first connecting portions 65b to the flange portion 63b, holding the connecting member 65 against the cylindrical shell 63, thus preventing the connecting member 65 from falling off the cylindrical shell 63. At this time, the radially outer surface of each of the first connecting portions 65b of the connecting member 65 is in contact with the radially inner surface of the connecting portion 63d of the cylindrical shell 63 due to elastic force. As a result, the connecting member 65 is electrically connected to the cylindrical shell 63, and external electromagnetic waves can be blocked.

[0031] Each of the multiple second connecting portions 65c is a plate-shaped member, extending along the axial direction X from the end of the annular portion 65a in the X1 direction as its base end. Specifically, the second connecting portion 65c is curved in a wave-like manner along the axial direction X, curving radially outward from the annular portion 65a, then curving radially inward, and finally curving radially outward again. The radially inward surface of the portion that curves radially inward again from the radially inward side is the fourth contact 65e.

[0032] As shown in Figure 2, when the connector 60 is attached to the housing 10, the second bush 16c, which is in contact with the small-diameter portion 63e and the connecting portion 63d of the cylindrical shell 63, is sandwiched between the connecting portion 63d and the first support portion 16b of the mating portion 16. At this time, the small-diameter portion 63e penetrates the first support portion 16b in the X2 direction. The second bush 16c has an annular plate shape made of an elastic material such as rubber. The connector 60 is fixed to the housing 10 by the elastic deformation of the second bush 16c.

[0033] In the connector 60 of this embodiment, the first connecting portion 65b is folded back 180 degrees and parallel to the axial direction X, so the radial length of the connecting member 65 does not increase. Furthermore, since the folded tip of the first connecting portion 65b has a cut-up portion 65d, the axial length of the annular portion 65a does not increase. In addition, by bringing the cut-up portion 65d and the flange portion 63b into contact, the electrical connection between the connecting member 65 and the cylindrical shell 63 can be made secure. In this way, a connector 60 that can suppress an increase in size while ensuring stable contact performance has been realized.

[0034] Furthermore, in the connector 60 of this embodiment, the flange portion 63b of the cylindrical shell 63 is connected to the cylindrical body portion 63a via connecting portions 63d, and multiple connecting portions 63d are arranged at equal intervals along the circumferential direction on the radially outer side of the cylindrical body portion 63a. This allows the cylindrical body portion 63a to evenly hold the flange portion 63b in the circumferential direction via the connecting portions 63d, and also ensures conductivity between the cylindrical body portion 63a and the flange portion 63b.

[0035] Furthermore, in the connector 60 of this embodiment, each of the multiple first connecting portions 65b of the connecting member 65 is positioned between adjacent connecting portions 63d in the circumferential direction. As a result, the radial length of the connector 60 does not increase in order to attach the connecting member 65, thus preventing the connector 60 from becoming larger.

[0036] [Method of manufacturing sockets] Next, a method for manufacturing the socket 100 including the connector 60 will be described. The signal terminals 61 of the connector 60 are formed by cutting or the like, and then the holder 62 is integrated by insert molding. The cylindrical shell 63 is formed by cutting. The connecting member 65 is formed using a press machine. The housing 10 is molded using a resin molding machine.

[0037] Next, the annular plate-shaped first bush 64 is attached to the cylindrical shell 63 from the X1 direction side so as to contact the second support portion 63c. Then, the signal terminal 61, which is integrated with the holder 62, is attached to the cylindrical shell 63 from the X1 direction side. At this time, the large diameter portion 63f of the cylindrical shell 63 is parallel to the small diameter portion 63e and is not inclined as shown in Figure 5. Therefore, the holder 62 is smoothly inserted into the cylindrical shell 63 without deformation. Upon insertion of the signal terminal 61, the inner circumferential surface of the first bush 64 elastically deforms and comes into close contact with the signal terminal 61, and the surface on the X1 direction side comes into contact with the holder 62. As a result, the first bush 64 is sandwiched between the second support portion 63c and the holder 62 with the surface on the X2 direction side in contact with the second support portion 63c (see Figure 5). In addition, the outer circumferential surface of the first bush 64 elastically deforms and comes into close contact with the inner circumferential surface of the small diameter portion 63e. At this time, the stopper 62a of the holder 62 is in contact with the step 63k on the inner circumference side of the boundary between the small diameter portion 63e and the large diameter portion 63f of the cylindrical shell 63. Subsequently, by plastically deforming the large diameter portion 63f so that it gradually decreases in diameter as it moves toward the X1 direction, the corner portion 62b of the stopper 62a of the holder 62 in the X1 direction comes into line contact with the inner circumference surface 63j which is decreasing in diameter toward the X1 direction (see Figure 5). In other words, the stopper 62a is held between the step 63k and the inner circumference surface 63j. As a result, the signal terminal 61 is held and fixed to the cylindrical shell 63, and the signal terminal 61 will not fall out of the cylindrical shell 63 in the X1 direction.

[0038] Next, the connecting member 65 is attached. The connecting member 65 is positioned such that each of the first connecting portions 65b fits between adjacent connecting portions 63d in the circumferential direction of the cylindrical shell 63 (see Figure 4), and is pushed in from the X1 direction side toward the X2 direction relative to the flange portion 63b. As described above, the outer diameter of the first connecting portion 65b excluding the cut-up portion 65d is slightly smaller than the inner diameter of the flange portion 63b, and the outer diameter of the cut-up portion 65d is slightly larger than the outer diameter of the flange portion 63b. Therefore, the first connecting portion 65b excluding the cut-up portion 65d passes through the flange portion 63b without deformation, and the cut-up portion 65d elastically deforms and passes through the flange portion 63b. Then, after passing through the flange portion 63b, the cut-up portion 65d returns to its original shape and becomes larger than the inner diameter of the flange portion 63b, and contacts the upper surface 63h of the flange portion 63b. This completes the attachment of the connecting member 65 to the cylindrical shell 63, and the assembly of the connector 60 is completed.

[0039] Finally, the second bush 16c is attached so as to contact the small-diameter portion 63e and the connecting portion 63d of the cylindrical shell 63 of the connector 60. At this time, the inner circumferential surface of the second bush 16c elastically deforms to adhere closely to the outer circumferential surface of the small-diameter portion 63e, and the surface on the X1 direction contacts the connecting portion 63d of the cylindrical shell 63. In this state, the connector 60 with the second bush 16c attached is inserted into the housing 10 from the side of the opening 14b toward the mating portion 16. Specifically, the connector 60 is inserted until the small-diameter portion 63e of the cylindrical shell 63 penetrates the first support portion 16b of the mating portion 16, and the upper surface 63h of the flange portion 63b of the cylindrical shell 63 contacts the second bottom surface 14f of the housing 10 (see Figure 2). At this time, the outer circumferential surface of the second bush 16c elastically deforms to adhere closely to the inner circumferential surface 16d of the mating portion 16, fixing the connector 60 to the housing 10. Furthermore, at this time, the second bush 16c is held between the first support portion 16b and the connecting portion 63d, with the surface on the X2 direction in contact with the first support portion 16b of the fitting portion 16. Note that when the connector 60 is attached to the housing 10, the tip of the cylindrical main body portion 63a is located within the internal space 16a of the fitting portion 16 of the housing 10.

[0040] [Other Embodiments] (1) In the above embodiment, eight first connecting portions 65b of the connecting member 65 and eight connecting portions 63d of the cylindrical shell 63 were arranged, but the invention is not limited to this. As long as an electrical connection can be ensured between the connecting member 65 and the cylindrical shell 63, the number of first connecting portions 65b and connecting portions 63d may be seven or fewer, or nine or more.

[0041] (2) In the above embodiment, one cut-up portion 65d is formed for one first connection portion 65b, but the embodiment is not limited thereto. Two or more cut-up portions 65d may be formed for one first connection portion 65b.

[0042] (3) In the above embodiment, the connector 60 was fixed to the housing 10 by elastically deforming the second bush 16c, but the invention is not limited to this. For example, the connector 60 may be fixed to the housing 10 by adhesive or other methods. [Industrial applicability]
