[0003] Patent Document 1: Japanese Patent Application Publication No. 2020-47360 Summary of the Invention The problem that the invention aims to solve

[0004] When the radial offset between a pair of coaxial connectors increases, the tilt of the other coaxial connector relative to the first coaxial connector also increases. In this case, the two coaxial connectors may interfere with each other.

[0009] [Description of embodiments of the present invention] First, embodiments of the present invention will be described.

[0010] The coaxial connector of the present invention is as follows.

[0011] (1) A coaxial connector for connection to a counterpart coaxial connector, the coaxial connector having an inner conductor and an outer conductor surrounding an outer peripheral side of the inner conductor, at least one of the inner conductor and the outer conductor having a cylindrical portion, a counterpart terminal of the counterpart coaxial connector being connected to the cylindrical portion, the cylindrical portion being connected to the counterpart terminal with the counterpart terminal disposed on the inner peripheral side or the outer peripheral side of the cylindrical portion, a portion of the top periphery of the cylindrical portion opposite to the counterpart terminal having an interference avoidance surface, the interference avoidance surface being inclined toward the side away from the counterpart terminal as it moves toward the top side of the cylindrical portion.

[0012] When connecting a coaxial connector to a peer coaxial connector, if the coaxial connector is tilted relative to the central axis of the peer coaxial connector, the top periphery of the barrel may approach the peer terminal. According to this coaxial connector, the portion of the top periphery of the barrel that faces the peer terminal tilts away from the peer terminal as it moves towards the top of the barrel. Therefore, even if the top periphery of the barrel approaches the peer terminal, contact with that peer terminal is prevented. Thus, even if the coaxial connector is tilted relative to the central axis of the peer coaxial connector, interference between the coaxial connector and the peer coaxial connector is less likely.

[0013] (2) In the coaxial connector of (1), the interference avoidance surface may also extend in a ring shape along the top periphery of the cylindrical part.

[0014] In this case, regardless of which direction the coaxial connector is tilted relative to the central axis of the other coaxial connector, the coaxial connector is not likely to interfere with the other coaxial connector.

[0015] (3) In the coaxial connector of (1) or (2), the interference avoidance surface can also guide the elastic sheet of the opposite terminal at the top periphery of the cylindrical part.

[0016] In this case, the elastic sheet can be guided by the interference-avoiding surface and can move smoothly to the inner or outer circumference of the cylinder.

[0017] (4) In any of (1) to (3) coaxial connectors, the interference avoidance surface may be formed on one of the inner and outer circumferential sides of the cylindrical part, and the other side of the inner and outer circumferential sides of the cylindrical part may be formed in a shape where the same diameter portion is continuous along the central axis of the cylindrical part.

[0018] In this case, for example, by chamfering the ends of the cylinder, an interference-avoiding surface can be easily formed.

[0019] (5) In any of the coaxial connectors in (1) to (4), the interference avoidance surface may be formed on one of the inner and outer peripheral sides of the cylindrical part, and the other side of the inner and outer peripheral sides of the cylindrical part may be formed in a shape that is inclined to the same side as the inclination of the interference avoidance surface.

[0020] In this case, for example, by bending the end of the cylinder, an interference-avoiding surface can be easily formed.

[0021] (6) In the coaxial connector of (5), a slit that divides the interference avoidance surface may also be formed at the top periphery of the cylindrical part.

[0022] Therefore, an interference-avoiding surface divided by slits can be easily formed around the top periphery of the cylinder.

[0023] (7) In the coaxial connector of (6), the width of the slit may also be smaller than the width of the elastic sheet of the opposite terminal.

[0024] Thus, the elastic sheet is not embedded in the slit but is smoothly guided to the inner or outer circumference of the cylinder.

[0025] (8) In any of the coaxial connectors in (1) to (7), the inner conductor may include an inner conductor tube portion that serves as the tube portion, the opposite terminal being inserted into the inner conductor tube portion, and an inner interference avoidance surface that serves as the interference avoidance surface is formed in the inner peripheral portion of the top periphery of the inner conductor tube portion.

[0026] Considering that when the counterparty terminal is inserted into the inner conductor cylinder, if the inner conductor is significantly tilted relative to the counterparty terminal, the inner circumferential portion of the top periphery of the inner conductor cylinder is prone to interference with the counterparty terminal. When an inner interference avoidance surface is formed in the inner circumferential portion of the top periphery of the inner conductor cylinder as an interference avoidance surface, even if the inner conductor is significantly tilted relative to the counterparty terminal, the inner circumferential portion of the top periphery of the inner conductor cylinder is less likely to interfere with the counterparty terminal.

[0027] (9) In any of (1) to (8) coaxial connectors, the outer conductor may include an outer conductor tube portion as the tube portion, the outer conductor tube portion being inserted into the opposite terminal, and an outer peripheral portion forming an outer interference avoidance surface as the interference avoidance surface in the outer peripheral portion of the top periphery of the outer conductor tube portion.

[0028] When the outer conductor tube is inserted into the counterpart terminal, if the outer conductor is tilted significantly relative to the counterpart terminal, the outer peripheral portion of the top edge of the outer conductor tube is prone to interference with the counterpart terminal. When an interference-avoiding surface is formed on the outer peripheral portion of the top edge of the outer conductor tube as an interference-avoiding surface, even if the outer conductor is tilted significantly relative to the counterpart terminal, the outer peripheral portion of the top edge of the tube is less likely to interfere with the counterpart terminal.

[0029] Furthermore, the connection structure of the coaxial connector of the present invention is as follows.

[0030] (10) A connection structure for a coaxial connector comprising a coaxial connector of any one of (1) to (9) and the other side coaxial connector, the other side coaxial connector having an other side inner conductor and an other side outer conductor surrounding the outer periphery of the other side inner conductor, the other side inner conductor having an inner elastic sheet that elastically contacts the inner conductor, and the other side outer conductor having an outer elastic sheet that elastically contacts the outer conductor.

[0031] In this configuration, the inner conductor on the opposite side has an inner elastic tab that elastically contacts the inner conductor, and the outer conductor on the opposite side has an outer elastic tab that elastically contacts the outer conductor. Therefore, by elastically deforming the inner and outer elastic tabs, the coaxial connector can be connected to the coaxial connector on the opposite side even if the coaxial connector is tilted relative to the coaxial connector on the opposite side. In this configuration, by avoiding interference surfaces, the coaxial connector is less likely to interfere with the coaxial connector on the opposite side.

[0032] (11) In the connection structure of the coaxial connector in (10), the coaxial connector on the other side may have a dielectric body on the other side located between the base end of the inner conductor on the other side and the base end of the outer conductor on the other side, and the dielectric body on the other side has an annular recess opposite to the coaxial connector.

[0033] In this case, because an annular recess is formed in the dielectric body on the other side, even if the coaxial connector is connected to the coaxial connector on the other side in an inclined state, the outer conductor is not easy to interfere with the dielectric body on the other side.

[0034] [Detailed Description of Embodiments of the Invention] The following description, with reference to the accompanying drawings, illustrates specific examples of the coaxial connector and its connection structure according to the present invention. It should be noted that the present invention is not limited to these examples, but is intended to include all modifications within the meaning and scope equivalent to the claims, as indicated by the claims.

[0035] [Implementation Method] The connection structure of the coaxial connector according to the embodiments will be described below. Figure 1 This is a perspective view of a device 10 equipped with a coaxial connector 70 and a coaxial connector connection structure 28. Figure 2 yes Figure 1 Sectional view along line II-II.

[0036] <Regarding the overall structure of the equipment> Device 10 is, for example, a camera device. The camera device may be, for example, a vehicle-mounted device. Device 10 may also not be a camera device.

[0037] The device 10 includes a housing 12, electrical components 20, and an external coaxial connector 30. The electrical components 20 are housed within the housing 12. The external coaxial connector 30 is a connector used to connect the electrical components 20 to external electrical components. For example, the external coaxial connector 30 is a connector for cables connected to external electrical components.

[0038] The housing 12 includes a first housing 13 and a second housing 14. The first housing 13 and the second housing 14 are formed, for example, from resin. The first housing 13 and the second housing 14 are combined to form a cuboid box-shaped housing 12 for housing the electrical components 20. In the case that the device 10 is a camera device, it is assumed that the first housing 13 has a lens or window for imaging, and the second housing 14 has a coaxial connector 30 for external connection.

[0039] More specifically, a retaining cylinder portion 16 protrudes from the bottom 15 of the housing 12. The retaining cylinder portion 16 is cylindrical and protrudes outward from the center of the bottom 15. The inner opening of the retaining cylinder portion 16 opens inside the second housing 14, and the outer opening of the retaining cylinder portion 16 opens outside the second housing 14. A retaining partition portion 17 is formed at the middle of the retaining cylinder portion 16 along its central axis X. In this embodiment, the retaining partition portion 17 is formed at the middle of the retaining cylinder portion 16 along the central axis X and near the inner opening. The retaining partition portion 17 separates the space on the inner opening side and the space on the outer opening side of the retaining cylinder portion 16. A retaining hole 17h is formed in the retaining partition portion 17, and an external coaxial connector 30 is inserted and held in the retaining hole 17h.

[0040] The coaxial connector 30 for external connection includes an inner conductor 32 for external connection, a dielectric body 34 for external connection, and an outer conductor 36 for external connection.

[0041] The inner conductor 32 for external connection is formed as an elongated rod and is made of a conductive material such as metal. The inner conductor 32 for external connection is an example of a pin-shaped inner conductor on the opposite side that is inserted into and connected to the inner conductor 80 described later. The dielectric body 34 for external connection is formed of an insulator such as resin and surrounds the inner conductor 32 for external connection. The outer conductor 36 for external connection is formed of a conductive material such as metal. The outer conductor 36 for external connection is formed as a cylinder surrounding the dielectric body 34 for external connection. The outer conductor 36 for external connection is an example of an outer conductor on the opposite side that connects to the outer conductor 90.

[0042] Electrical component 20 is, for example, a mounting substrate on which electronic components are mounted. In the case that device 10 is a camera device, it is assumed that electrical component 20 is a circuit board 21 and an imaging element 22 mounted on that circuit board 21. The imaging element 22 is positioned opposite a lens or window for imaging in the first housing 13, and the lens or window is rotated to capture images of the external scenery. Hereinafter, the side of the imaging element 22 facing the first housing 13 is sometimes referred to as the front side, and the side opposite to it, the second housing 14, is referred to as the rear side.

[0043] A coaxial connector connection structure 28 is installed in device 10. The coaxial connector connection structure 28 is a connection structure between the substrate coaxial connector 40 and the coaxial connector 70.

[0044] In this embodiment, a coaxial connector 40 for the substrate is provided on the side of the circuit board 21 opposite to the imaging element 22. The coaxial connector 40 for the substrate is fixed to the circuit board 21. The coaxial connector 40 for the substrate is an example of a coaxial connector on the opposite side that is connected to the coaxial connector 70.

[0045] The coaxial connector 40 for a substrate includes a counterpart inner conductor 50 and a counterpart outer conductor 60 surrounding the outer periphery of the counterpart inner conductor 50. The coaxial connector 40 for a substrate may further include a counterpart dielectric body 42 located between the counterpart inner conductor 50 and the counterpart outer conductor 60.

[0046] The opposing dielectric 42 surrounds the opposing inner conductor 50. The opposing dielectric 42 is formed of an insulator. The opposing outer conductor 60 surrounds the opposing dielectric 42. The base ends of the opposing inner conductor 50 and the opposing outer conductor 60 are fixed to the circuit board 21 by soldering or the like. Thus, the opposing inner conductor 50 and the opposing outer conductor 60 are electrically connected to the circuit board 21 and are fixed in a state protruding from the circuit board 21. The board coaxial connector 40 protrudes from the circuit board 21 toward the external connection coaxial connector 30.

[0047] Coaxial connector 70 is connected to substrate coaxial connector 40. Coaxial connector 70 includes an inner conductor 80, an outer conductor 90 surrounding the outer periphery of the inner conductor 80, and a dielectric body 72 located between the inner conductor 80 and the outer conductor 90. The dielectric body 72 surrounds the inner conductor 80. The dielectric body 72 is made of an insulator. The outer conductor 90 surrounds the dielectric body 72. Coaxial connector 70 is connected to substrate coaxial connector 40 with the inner conductor 50 inserted and connected to the inner conductor 80 on the opposite side, and the outer conductor 90 inserted and connected to the outer conductor 60 on the opposite side. Coaxial connector 70 protrudes further from substrate coaxial connector 40 toward external connection coaxial connector 30. Coaxial connector 70 relays the connection between substrate coaxial connector 40 and external connection coaxial connector 30. Coaxial connector 70 can be connected with varying orientations relative to substrate coaxial connector 40 and external connection coaxial connector 30. Coaxial connector 70 can also be considered as a relay coaxial connector.

[0048] An external coaxial connector 30 is disposed on the side of the second housing 14, i.e., the rear side of the housing 12. Inside the housing 12, a coaxial connector 70 is connected to the external coaxial connector 30. An external electrical component that is the connection object of the cable is connected to the external coaxial connector 30, thereby electrically connecting the external electrical component to the electrical component 20 inside the housing 12.

[0049] Within the housing 12, the circuit board 21 is supported in a fixed position. By design, the position of the coaxial connector 40 for the board relative to the external coaxial connector 30 is set to a fixed position. However, the position of the coaxial connector 40 for the board relative to the external coaxial connector 30 may deviate from the designed position within tolerance limits.

[0050] In this embodiment, the insertion depth of the coaxial connector 70 relative to the coaxial connector 40 on the substrate can be adjusted within a range that allows electrical contact to be maintained between the inner conductor 50 and the inner conductor 80 on the opposite side, and between the outer conductor 60 and the outer conductor 90 on the opposite side. Furthermore, the coaxial connector 70 can be inserted into and connected to the coaxial connector 40 on the substrate and the external connection coaxial connector 30 in an inclined state. Therefore, during the assembly of this device 10 or in its completed state, even if the distance between the external connection coaxial connector 30 and the coaxial connector 40 on the substrate changes, this distance change can be absorbed by adjusting the insertion depth of the coaxial connector 70 relative to the coaxial connector 40 on the substrate. Additionally, even if the external connection coaxial connector 30 deviates from its coaxially opposed position relative to the coaxial connector 40 on the substrate, this positional deviation can be absorbed by tilting the coaxial connector 70 relative to both the coaxial connector 40 and the external connection coaxial connector 30.

[0051] When the tilt of the coaxial connector 70 relative to the coaxial connector 40 for the substrate increases, it is possible that a portion of the top periphery of the circuit board 21 side of the outer conductor 90 approaches the opposite outer conductor 60 and interferes with it. Additionally, it is possible that a portion of the top periphery of the circuit board 21 side of the inner conductor 80 approaches the opposite inner conductor 50 and interferes with it.

[0052] For example, within the tolerance range, when the coaxial connector 70 is closest to the substrate coaxial connector 40 and the external connection coaxial connector 30 is furthest from its coaxially opposed position relative to the substrate coaxial connector 40, the tilt of the coaxial connector 70 relative to the substrate coaxial connector 40 is considered to be at its maximum. When the coaxial connector 70 is at its maximum tilt relative to the substrate coaxial connector 40, the requirement to avoid interference between the coaxial connector 70 and the substrate coaxial connector 40 is very high.

[0053] It should be noted that, assuming the relative positional relationship of the coaxial connectors 40 and 70 can vary within the tolerance range, the inner conductor 80 and outer conductor 90 are designed to ensure reliable connection and achieve the desired communication performance. Therefore, it can be assumed that by shortening the protruding length of the top periphery of the inner conductor 80 and outer conductor 90, the aforementioned interference can be difficult to avoid.

[0054] Based on the connection structure of the coaxial connector 40 and coaxial connector 70 for the substrate, the structure for avoiding the above-mentioned interference will be described.

[0055] <Regarding the connection structure of coaxial connectors> The connection structure 28 of the coaxial connector will be described in more detail. Figure 3 This is a perspective view showing the connection structure 28 of the coaxial connector. Figure 4This is an exploded three-dimensional view showing the same connection structure. Figure 5 yes Figure 3 Enlarged sectional view. Figure 6 This is a perspective view showing the top of the coaxial connector 70. Figure 6 Elastic sheets 56 and 66 are shown in the middle section.

[0056] After a more detailed description of the coaxial connector 40 and coaxial connector 70 for the substrate, a more detailed description of the structure for avoiding interference will be given.

[0057] <About Coaxial Connectors for Substrates> As described above, the coaxial connector 40 for the substrate includes a peer-side inner conductor 50, a peer-side outer conductor 60, and a peer-side dielectric body 42.

[0058] The inner conductor 50 on the opposite side is an elongated conductive component. In this embodiment, the inner conductor 50 on the opposite side is formed by stamping a metal sheet. It should be noted that the inner conductor on the opposite side can also be formed by machining a metal material.

[0059] More specifically, the opposite-side inner conductor 50 includes the opposite-side inner conductor cylindrical portion 52 and the inner elastic sheet 56.

[0060] The inner conductor cylindrical portion 52 on the opposite side is formed in a cylindrical shape, more specifically, in a cylindrical shape. The base end of the inner conductor 50 on the opposite side is housed and held in the dielectric body 42 on the opposite side. It should be noted that in the coaxial connector 40 for the substrate, the top end is the end on the side connected to the coaxial connector 70, and the base end is the end on the opposite side of the top end, which in this case is the end facing the circuit board 21.

[0061] A positioning piece 53 is formed protruding outward from a portion of the base end of the inner conductor cylinder portion 52 on the opposite side. The positioning piece 53 is a plate-shaped portion along the central axis of the inner conductor cylinder portion 52 on the opposite side; in this embodiment, it is a square plate-shaped portion. The positioning piece 53 has a structure of two overlapping plate-shaped portions. In this embodiment, the inner conductor cylinder portion 52 on the opposite side is formed by stamping the plate-shaped portions to form a cylinder. The plate-shaped portions protrude outward from two adjacent edges of the cylinder's seam, and the positioning piece 53 is formed by the overlapping of these two plate-shaped portions.

[0062] An anti-detachment protrusion 53p is formed at the protruding end 53e of the positioning piece 53, and the anti-detachment protrusion 53p hooks onto the bottom of the positioning groove 44 of the opposite dielectric body 42. The anti-detachment protrusion 53p is shaped to hook onto the bottom of the positioning groove 44 so that one of the opposite inner conductor cylinders 52 is not easily detached from the top side relative to the opposite dielectric body 42. Here, the anti-detachment protrusion 53p is formed in the shape of a triangular plate. The edge of the anti-detachment protrusion 53p on the top side of the opposite inner conductor cylinder 52 is more inclined relative to the central axis X than the edge of the anti-detachment protrusion 53p on the base side of the opposite inner conductor cylinder 52. Therefore, the anti-detachment protrusion 53p can be easily pressed into the base side of the opposite inner conductor cylinder 52 relative to the positioning groove 44, and is not easily detached from the top side of the opposite inner conductor cylinder 52. The positioning piece 53 and the anti-detachment protrusion 53p can also be omitted.

[0063] Alternatively, a locking tab 52a may be formed on the inner conductor cylinder portion 52 on the opposite side. The locking tab 52a hooks onto the inner circumferential surface of the dielectric body 42 on the opposite side when it is pressed into the dielectric body 42 on the opposite side. Alternatively, a protruding tab 52b may be provided at the base end of the inner conductor cylinder portion 52 on the opposite side. The protruding tab 52b extends along the main surface of the circuit board 21 and is used for soldering.

[0064] The inner elastic tab 56 protrudes from the top end of the opposite inner conductor tube portion 52. In this embodiment, a plurality of (three in this case) inner elastic tabs 56 extend circumferentially spaced from the top end of the opposite inner conductor tube portion 52. Preferably, the plurality of inner elastic tabs 56 are located at equal intervals around the central axis X of the opposite inner conductor tube portion 52.

[0065] The inner elastic sheet 56 includes: an inclined portion 56a that is inclined outward from the top end of the inner conductor tube portion 52 on the opposite side; and a curved portion 56b that is connected to the top end of the inclined portion 56a to form an outwardly protruding curved shape.

[0066] When multiple inner elastic tabs 56 are inserted into the inner conductor 80, the inclined portion 56a elastically deforms inward, while the outward-facing top of the bent portion 56b elastically presses against the inner circumferential surface of the inner conductor 80. Thus, the inner elastic tabs 56 and the inner conductor 80 are in elastic contact, maintaining an electrical connection between the inner conductor 50 and the inner conductor 80.

[0067] It should be noted that there can be two or more elastic sheets.

[0068] The opposite-side dielectric body 42 is formed into a circular plate shape from resin or the like. The maximum thickness of the opposite-side dielectric body 42 is less than the length of the opposite-side inner conductor cylinder 52. The opposite-side dielectric body 42 is, for example, a molded resin component.

[0069] An insertion hole 43 is formed in the center of the dielectric body 42 on the opposite side, and the base end of the inner conductor 50 on the opposite side, more specifically the base end of the inner conductor cylindrical portion 52 on the opposite side, is inserted into the insertion hole 43. In addition, a positioning groove 44 is formed in which the positioning piece 53 is embedded. The positioning groove 44 is formed as a groove extending from a portion of the circumferential direction of the insertion hole 43 toward the outer peripheral recess and along the central axis X.

[0070] Furthermore, the inner conductor tube 52 on the opposite side is inserted into the insertion hole 43, thereby inserting and holding the inner conductor 50 on the opposite side dielectric body 42. Preferably, the inner conductor tube 52 on the opposite side is pressed in and held in the insertion hole 43.

[0071] If the inner conductor on the opposite side is a machined product, the aforementioned press-fit structure easily and securely holds the inner conductor on the opposite side to the dielectric body. In the case where the inner conductor 50 on the opposite side is a stamped metal sheet, a positioning piece 53 is embedded in the positioning groove 44 to improve holding strength. The positioning piece 53 is held by the inner circumferential surface of the positioning groove 44, thereby easily and securely holding the inner conductor 50 on the opposite side to the dielectric body 42.

[0072] In addition, by hooking the anti-detachment protrusion 53p of the positioning piece 53 into the bottom of the positioning groove 44, the inner conductor 50 on the opposite side is not easily pulled out from the dielectric body 42 on the opposite side, and the inner conductor 50 on the opposite side is held more firmly.

[0073] Furthermore, a retaining annular protrusion 45 is formed in the portion of the dielectric body 42 surrounding the insertion hole 43, protruding in an annular shape toward the top end of the inner conductor 50. By retaining the inner conductor cylindrical portion 52, the inner conductor 50 is held more securely, and the inner conductor 50 is less likely to tilt relative to the dielectric body 42.

[0074] The outer peripheral surface of the opposite-side dielectric 42 is formed into a short cylindrical circumferential shape that can be inserted into the inner peripheral portion of the opposite-side outer conductor 60. An annular protrusion 46 is formed on the outer peripheral portion of the opposite-side dielectric 42 on the opposite-side outer conductor 60 side, protruding in a ring shape towards the tip of the opposite-side inner conductor 50. The outer peripheral surface of the opposite-side dielectric 42 and the annular protrusion 46 are correspondingly wider in the central axis X direction. Therefore, the outer peripheral surface of the opposite-side dielectric 42 can face the inner peripheral surface of the opposite-side outer conductor 60 with a wide area. As a result, the opposite-side dielectric 42 is easily and firmly held to the opposite-side outer conductor 60, and the opposite-side outer conductor 60 is less likely to tilt relative to the opposite-side dielectric 42. Therefore, the opposite-side inner conductor 50 and the opposite-side outer conductor 60 are easily maintained in a coaxial positional relationship.

[0075] In the portion of the dielectric body 42 opposite to the coaxial connector 70, an annular recess 47 is formed between the retaining annular protrusion 45 in the inner periphery of the dielectric body 42 and the outer peripheral annular protrusion 46 in the outer periphery.

[0076] When the coaxial connector 70 is tilted significantly relative to the coaxial connector 40 for the substrate, if the periphery of the top edge of the outer conductor 90 is too close to the dielectric body 42 on the other side, the periphery of the top edge can enter the annular recess 47.

[0077] The outer conductor 60 on the opposite side is formed of a conductive material such as metal and surrounds the dielectric body 42 on the opposite side. Therefore, the dielectric body 42 on the opposite side is a cylindrical member between the inner conductor 50 on the opposite side and the outer conductor 60 on the opposite side. The outer conductor 60 on the opposite side is formed, for example, by stamping a metal sheet.

[0078] In this embodiment, the opposite-side outer conductor 60 includes an opposite-side outer conductor tube portion 62 and an outer elastic sheet 66 protruding from the top end of the opposite-side outer conductor tube portion 62.

[0079] The outer conductor cylindrical portion 62 on the opposite side is formed into a cylindrical shape, more specifically, into a cylindrical shape, so that the dielectric body 42 on the opposite side can be disposed inside. The dielectric body 42 on the opposite side is housed and held at the base end portion of the outer conductor cylindrical portion 62 on the opposite side.

[0080] Alternatively, a locking piece 62a may be formed on the outer conductor tube portion 62 on the opposite side, which hooks onto the outer peripheral surface of the dielectric body 42 on the opposite side when the dielectric body 42 is pressed in.

[0081] Outer elastic tabs 66 protrude from the top end of the opposite-side outer conductor tube portion 62. In this embodiment, a plurality of (eight in this case) outer elastic tabs 66 extend circumferentially spaced from the top end of the opposite-side outer conductor tube portion 62. Preferably, the plurality of outer elastic tabs 66 are located at equal intervals around the central axis X of the opposite-side outer conductor tube portion 62.

[0082] The outer elastic sheet 66 includes: an inclined portion 66a that is inclined inward from the top end of the opposite outer conductor tube portion 62; and a curved portion 66b that is connected to the top end of the inclined portion 66a to form an inwardly protruding curved shape.

[0083] When the multiple outer elastic tabs 66 are embedded in the outer conductor 90, the inclined portion 66a elastically deforms outward, while the inward-facing top of the bent portion 66b elastically presses against the outer peripheral surface of the outer conductor 90. Thus, the outer elastic tabs 66 and the outer conductor 90 are in elastic contact, maintaining an electrical connection between the outer conductor 60 and the outer conductor 90.

[0084] It should be noted that there can be seven or fewer elastic sheets, or nine or more.

[0085] In the X-axis direction, the length of the outer conductor tube 62 on the opposite side is greater than the thickness of the dielectric body 42 on the opposite side. Furthermore, in this embodiment, the length of the outer conductor tube 62 on the opposite side is greater than the length of the inner conductor 50 on the opposite side. Additionally, the base of the outer elastic sheet 66 is located further away from the dielectric body 42 than the base of the inner elastic sheet 56. Further, the tip of the outer elastic sheet 66 is located further away from the dielectric body 42 than the tip of the inner elastic sheet 56. However, the bent portions 56b and 66b can contact the inner conductor 80 or the outer conductor 90 at the same position on the X-axis.

[0086] The coaxial connector 40 for the substrate can also be surrounded by a cylindrical connector retainer 41. The connector retainer 41 is a component formed of resin or the like, which surrounds the substrate with the coaxial connector 40 to prevent contact with other components.

[0087] <About Coaxial Connectors> As described above, the shaft connector 70 includes an inner conductor 80, an outer conductor 90, and a dielectric body 72.

[0088] The inner conductor 80 is an elongated conductive member. In this embodiment, the inner conductor 80 is formed by stamping a metal sheet. More specifically, the inner conductor 80 includes an inner conductor cylindrical portion 82 and an inner conductor extension cylindrical portion 86.

[0089] The inner conductor tube portion 82 is formed in a cylindrical shape, more specifically, in a circular shape. The open end of the inner conductor tube portion 82 faces the coaxial connector 40 for the substrate. The inner conductor tube portion 82 is the portion that connects to the inner conductor 50 on the opposite side.

[0090] More specifically, the inner conductor tube 82 is a tube that is slender along its central axis X. The inner diameter of the inner conductor tube 82 is smaller than the outer diameter of the imaginary circle that connects the tops of the plurality of inner elastic plates 56. The plurality of inner elastic plates 56 can elastically deform inward while elastically contacting the inner circumferential surface of the inner conductor tube 82.

[0091] In the X-axis direction, the inner conductor cylinder 82 is longer than the inner elastic sheet 56. In the X-axis direction, the top of the bent portion 56b of the inner elastic sheet 56 contacts any position on the inner circumferential surface of the inner conductor cylinder 82, thereby enabling connection between the opposing inner conductors 50 and 80. This allows for positional offsets between the opposing inner conductors 50 and 80 in the X-axis direction.

[0092] The inner conductor extension section 86 is located on the side opposite to the coaxial connector 40 for the substrate, relative to the inner conductor section 82 described above. In this embodiment, the inner conductor extension section 86 is thinner than the inner conductor section 82. The inner conductor extension section 86 is connected to the inner conductor section 82 via a tapered portion 81. The tapered portion 81 is a tapered portion that gradually tapers from the inner conductor section 82 toward the inner conductor extension section 86. The inner conductor extension section may also be connected to the inner conductor section via a stepped portion.

[0093] The inner conductor extension tube 86 may also have an elastic sheet 87 protruding towards the top end. The elastic sheet 87 is configured to elastically deform in the inward and outward directions. The outer connection inner conductor 32 is inserted from the top end side of the two elastic sheets 87 towards the space between the two elastic sheets 87. The outer connection inner conductor 32 is sandwiched between the two elastic sheets 87, thereby connecting the inner conductor 80 to the outer connection inner conductor 32.

[0094] Alternatively, a locking piece 86a may be formed in the inner conductor extension tube 86 to lock with the dielectric body 72.

[0095] The dielectric body 72 is formed of resin or the like. The dielectric body 72 is, for example, a molded resin component.

[0096] The dielectric body 72 is formed into a cylindrical shape capable of housing at least a portion of the inner conductor 80. In this embodiment, the dielectric body 72 is formed into a cylindrical shape. The inner conductor extension cylindrical portion 86 is housed within the dielectric body 72. The internal space of the inner conductor extension cylindrical portion 86 is formed to hold the base end of the inner conductor extension cylindrical portion 86 in a press-in state and to allow the elastic sheet 87 to elastically deform in the inward and outward directions to a certain extent.

[0097] By contacting one end of the dielectric body 72 with the tapered portion 81, the dielectric body 72 can be positioned relative to the inner conductor 80. The inner conductor cylindrical portion 82 extends further toward the coaxial connector 40 for the substrate than the dielectric body 72.

[0098] An outer conductor 90 is disposed on the outer periphery of the dielectric body 72. The outer conductor 90 is formed of a conductive material such as metal and surrounds the dielectric body 72. The outer conductor 90 is formed, for example, by stamping a metal plate.

[0099] The outer conductor 90 has an outer conductor cylindrical portion 92 and an outer conductor extension cylindrical portion 96.

[0100] The outer conductor tube portion 92 is formed in a cylindrical shape, more specifically, in a cylindrical shape. The open end of the outer conductor tube portion 92 faces the coaxial connector 40 for the substrate. The outer conductor tube portion 92 is the portion that connects to the opposite outer conductor 60.

[0101] The outer conductor tube portion 92 is located at intervals on the outer periphery of the inner conductor tube portion 82. The outer diameter of the outer conductor tube portion 92 is larger than the outer diameter of the imaginary circle connecting the tops of the plurality of outer elastic plates 66. The plurality of outer elastic plates 66 can elastically deform outward while elastically contacting the outer peripheral surface of the outer conductor tube portion 92.

[0102] In the X-axis direction, the outer conductor cylinder 92 is longer than the outer elastic sheet 66. In the X-axis direction, the top of the bent portion 66b of the outer elastic sheet 66 contacts any position on the outer peripheral surface of the outer conductor cylinder 92, thereby enabling connection to the opposite outer conductor 60 and outer conductor 90. This allows for positional offsets between the opposite outer conductor 60 and outer conductor 90 in the X-axis direction.

[0103] The outer conductor extension tube 96 is located on the side opposite to the coaxial connector 40 for the substrate, relative to the outer conductor tube 92 described above. In this embodiment, the outer conductor extension tube 96 is thinner than the outer conductor tube 92. The outer conductor extension tube 96 is connected to the outer conductor tube 92 via a tapered portion 91. The tapered portion 91 is a tapered portion that gradually tapers from the outer conductor tube 92 toward the outer conductor extension tube 96. The outer conductor extension tube may also be connected to the outer conductor tube via a stepped portion.

[0104] The outer conductor extension tube 96 may also have an elastic sheet 97 protruding towards the top end. The elastic sheet 97 is configured to elastically deform in the inward and outward directions. The outer conductor 36 for external connection is externally fitted from the top end side of the plurality of elastic sheets 97 to the outer periphery of the plurality of elastic sheets 97. The outer conductor 90 is connected to the outer conductor 36 for external connection by the plurality of elastic sheets 97 being elastically pressed against the inner peripheral surface of the outer conductor 36 for external connection.

[0105] Alternatively, a locking piece 96a may be formed in the outer conductor extension tube 96 to lock with the dielectric body 72.

[0106] <Regarding structures used to avoid interference> At least one of the inner conductor 80 and the outer conductor 90 has a cylindrical portion 82, 92, and the opposite-side terminal of the coaxial connector 40 for the substrate is connected to the cylindrical portion 82, 92. In this embodiment, the opposite-side inner conductor 50 of the coaxial connector 40 for the substrate is an example of an opposite-side terminal, and the opposite-side outer conductor 60 is also an example of an opposite-side terminal.

[0107] The inner conductor 80 has an inner conductor cylindrical portion 82 that serves as a cylindrical portion. The inner conductor cylindrical portion 82 is connected to the opposing inner conductor 50, which serves as an opposing terminal, with the opposing inner conductor 50 disposed on the inner circumferential side of the inner conductor cylindrical portion 82.

[0108] The outer conductor 90 has an outer conductor tube portion 92 that serves as a tube portion. The outer conductor tube portion 92 is connected to the opposite-side outer conductor 60, which is disposed on the outer periphery of the outer conductor tube portion 92 as the opposite-side terminal.

[0109] The portions of the top periphery of the cylindrical portions 82 and 92 that are opposite to the opposite-side inner conductor 50 or opposite-side outer conductor 60, which are opposite-side terminals, have interference-avoiding surfaces 83 and 93. The interference-avoiding surfaces 83 and 93 are formed to be inclined away from the opposite-side inner conductor 50 and opposite-side outer conductor 60, which are opposite-side terminals, as they face the top side of the cylindrical portions 82 and 92.

[0110] The explanation will focus on the interference-avoiding surface 83 of the inner conductor tube portion 82. The inner conductor tube portion 82 is located closer to the opposite-side inner conductor 50 than the opposite-side outer conductor 60 between the opposite-side inner conductor 50 and the opposite-side outer conductor 60. Therefore, when the coaxial connector 70 is tilted relative to the coaxial connector 40 for the substrate, the top periphery of the inner conductor tube portion 82 is more likely to contact the opposite-side inner conductor 50 than the opposite-side outer conductor 60.

[0111] Therefore, the interference avoidance surface 83 is formed on the inner peripheral portion of the top periphery of the inner conductor cylinder 82, facing the inner elastic sheet 56. Furthermore, the interference avoidance surface 83 is formed as a surface that slopes away from the inner elastic sheet 56 as it approaches the top of the inner conductor cylinder 82. In other words, the interference avoidance surface 83 is formed in a manner that slopes outwards as it approaches the top of the inner conductor cylinder 82. The interference avoidance surface 83 can also be referred to as the inner interference avoidance surface 83.

[0112] The interference-avoiding surface 83 preferably extends in a ring shape along the top periphery of the inner conductor cylinder 82. In this case, even if the inner conductor cylinder 82 is tilted in all directions relative to the opposite inner conductor 50, interference between the inner conductor cylinder 82 and the opposite inner conductor 50 can be easily avoided.

[0113] Alternatively, a recess 83a may be formed on the interference avoidance surface 83, but not reaching the base of the interference avoidance surface 83. The recess 83a, which does not reach the base of the interference avoidance surface 83, does not negate the continuity of the interference avoidance surface 83, which extends in a ring along the top periphery of the inner conductor cylinder portion 82.

[0114] A slit 83b may also be formed on the interference-avoiding surface 83 to facilitate processing. The slit 83b has a width S1 that is smaller than the width W1 of the inner elastic sheet 56 (see reference). Figure 6 The continuity of the interference avoidance surface 83, which extends in a ring along the top periphery of the inner conductor tube 82, is not denied.

[0115] The interference avoidance surface 83 does not necessarily have to extend in a ring shape along the top periphery of the inner conductor cylinder portion 82. For example, if the inclination direction of the coaxial connector 70 relative to the coaxial connector 40 for the substrate is determined, the interference avoidance surface may also be formed in the portion of the top periphery of the inner conductor cylinder portion 82 that could interfere with the inner conductor on the opposite side due to the inclination.

[0116] The interference avoidance surface 83 is preferably formed at the position where the inner elastic sheet 56 is guided around the top periphery of the inner conductor cylinder portion 82. For example, when the connection posture of the coaxial connector 70 and the substrate coaxial connector 40 is fixed around the central axis X, it is sufficient to form the interference avoidance surface 83 at the same position as the inner elastic sheet around the central axis X.

[0117] If the interference avoidance surface 83 extends in a ring shape along the top periphery of the inner conductor cylinder 82, the interference avoidance surface 83 can guide the inner elastic sheet 56 regardless of the connection posture of the coaxial connector 70 and the coaxial connector 40 for the substrate around the central axis X.

[0118] The interference avoidance surface 83 can be formed simply as an inner circumference of the top periphery of the inner conductor cylinder 82, and its formation method is not limited. For example, the interference avoidance surface 83 can also be formed by cutting off the inner circumference of the top periphery of the inner conductor cylinder 82, or by rolling the top periphery of the inner conductor cylinder 82 into a thinner shape towards the top, or by stamping the top periphery of the inner conductor cylinder 82 to make it bend, or by a combination of these processes.

[0119] In this embodiment, the interference avoidance surface 83 is formed by stamping the periphery of the top end of the inner conductor cylinder 82 to bend it. In this case, both the inner and outer peripheral surfaces of the top end of the inner conductor cylinder 82 are bent in the same direction. Therefore, the outer peripheral surface portion of the inner conductor cylinder 82 on the side opposite to the interference avoidance surface 83 is formed in a shape that is inclined along the interference avoidance surface 83 on the outer peripheral side of the interference avoidance surface 83.

[0120] If the interference avoidance surface 83 is formed by stamping the periphery of the top end of the inner conductor cylinder 82 to make it bend, it is easy to make the interference avoidance surface 83 bend more significantly.

[0121] The explanation will focus on the interference avoidance surface 93 of the outer conductor tube 92.

[0122] The outer conductor tube portion 92 is located closer to the opposite side outer conductor 60 than the opposite side inner conductor 50 between the opposite side inner conductor 50 and the opposite side outer conductor 60. Therefore, when the coaxial connector 70 is tilted relative to the coaxial connector 40 for the substrate, the top periphery of the outer conductor tube portion 92 is more likely to contact the opposite side outer conductor 60 than the opposite side inner conductor 50.

[0123] Therefore, the interference avoidance surface 93 is formed on the outer peripheral portion of the top edge of the outer conductor cylinder 92 facing the outer elastic sheet 66. Furthermore, the interference avoidance surface 93 is formed as a surface that slopes away from the outer elastic sheet 66 as it approaches the top edge of the outer conductor cylinder 92. In other words, the interference avoidance surface 93 is formed as it slopes inward as it approaches the top edge of the outer conductor cylinder 92. The interference avoidance surface 93 can also be referred to as the outer interference avoidance surface 93.

[0124] The interference avoidance surface 93 preferably extends in a ring shape along the top periphery of the outer conductor cylinder 92. In this case, even if the outer conductor cylinder 92 is tilted in all directions relative to the opposite outer conductor 60, interference between the outer conductor cylinder 92 and the opposite outer conductor 60 can be easily avoided.

[0125] Recesses 93a and 93b may also be formed on the interference avoidance surface 93 to a degree that does not reach the base of the interference avoidance surface 93. The recesses 93a and 93b that do not reach the base of the interference avoidance surface 93 do not negate the continuity of the interference avoidance surface 93 that extends in a ring along the top periphery of the outer conductor cylinder portion 92.

[0126] The interference avoidance surface 93 does not necessarily have to extend in a ring shape along the top periphery of the outer conductor cylinder portion 92. For example, if the inclination direction of the coaxial connector 70 relative to the coaxial connector 40 for the substrate is determined, the interference avoidance surface may also be formed in the portion of the top periphery of the outer conductor cylinder portion 92 that could interfere with the opposite outer conductor due to the inclination.

[0127] The interference avoidance surface 93 is preferably formed at the position where the outer elastic sheet 66 is guided at the top periphery of the outer conductor tube portion 92. For example, when the connection posture of the coaxial connector 70 and the substrate coaxial connector 40 is fixed around the central axis X, it is sufficient to form the interference avoidance surface 93 at the same position as the outer elastic sheet around the central axis X.

[0128] If the interference avoidance surface 93 extends in a ring shape along the top periphery of the outer conductor cylinder 92, then the interference avoidance surface 93 can guide the outer elastic sheet 66 regardless of the connection posture of the coaxial connector 70 around the central axis X and the coaxial connector 40 for the substrate.

[0129] The interference avoidance surface 93 can be formed on the outer periphery of the top edge of the outer conductor cylinder 92, and its formation method is not limited. For example, the interference avoidance surface 93 can also be formed by cutting off the outer periphery of the top edge of the outer conductor cylinder 92, or by rolling the top edge of the outer conductor cylinder 92 into a thinner shape towards the top, or by stamping (e.g., deep drawing) the top edge of the outer conductor cylinder 92 to make it bend.

[0130] In this embodiment, an interference-avoiding surface 93 is formed by removing the outer periphery of the top edge of the outer conductor cylinder portion 92. The process of removing the outer periphery of the top edge of the outer conductor cylinder portion 92 to form the interference-avoiding surface 93 can also be referred to as a chamfering process.

[0131] In this case, the inner circumference of the outer conductor cylinder 92 on the side opposite to the interference avoidance surface 93 is formed into a shape in which the same diameter portion is continuous along the central axis X of the outer conductor cylinder 92. That is, the inner circumferential surface of the outer conductor cylinder 92 retains the original shape from when the outer conductor cylinder 92 was machined into a circle.

[0132] If the inner periphery of the outer conductor cylinder 92, on the side opposite to the interference avoidance surface 93, is formed in a shape where the same diameter portion is continuous along the central axis X, the distance between the outer conductor cylinder 92 and the central axis X can be easily kept fixed. This reduces the variation in distance between the inner and outer conductors, and easily maintains the communication performance of the coaxial connector's connection structure 28.

[0133] The larger the angle between the interference avoidance surfaces 83 and 93 and the central axis X, the easier it is to avoid interference at the top periphery of the cylinders 82 and 92. In addition, the longer the length of the interference avoidance surfaces 83 and 93 along the central axis X, the easier it is to avoid interference at the top periphery of the cylinders 82 and 92.

[0134] In this embodiment, the inclination of the interference avoidance surface 83 relative to the central axis X is greater than that of the interference avoidance surface 93 relative to the central axis X. Conversely, the length of the interference avoidance surface 83 along the direction of the central axis X is shorter than the length of the interference avoidance surface 93 along the direction of the central axis X.

[0135] Therefore, appropriate interference-avoidance shapes are formed at the top periphery of the cylindrical portions 82 and 92, respectively.

[0136] Regarding the tilt of the interference-avoiding surfaces 83 and 93 relative to the central axis X and their length along the direction of the central axis X, the maximum tilt angle of the coaxial connector 70 relative to the coaxial connector 40 for the substrate that can be generated within the tolerance range can be set to a value that can avoid interference between the two coaxial connectors 40 and 70.

[0137] <Connector connection action and connection structure under tilt conditions> When the coaxial connector 70 is connected to the coaxial connector 40 for the substrate, a plurality of inner elastic tabs 56 of the opposite inner conductor 50 are inserted into the inner conductor tube 82, and the outer conductor tube 92 is inserted into a plurality of outer elastic tabs 66 of the opposite outer conductor 60.

[0138] At this time, through the contact between the multiple inner elastic pieces 56 and the interference avoidance surface 83 of the inner conductor cylinder 82, the multiple inner elastic pieces 56 are smoothly guided to the inner circumferential surface of the inner conductor cylinder 82 while shifting inwards (see reference). Figure 5 (Arrow P1). Furthermore, by contacting the interference avoidance surface 93 of the outer conductor cylinder 92 with the multiple outer elastic tabs 66, the multiple outer elastic tabs 66 are smoothly guided to the inner outer peripheral surface of the outer conductor cylinder 92 while shifting outwards (see reference). Figure 5 Arrow P2).

[0139] Therefore, multiple inner elastic tabs 56 can be prevented from hooking onto the top periphery of the inner conductor tube portion 82 or multiple outer elastic tabs 66 can be prevented from hooking onto the top periphery of the outer conductor tube portion 92, so that the coaxial connector 70 can be smoothly connected to the coaxial connector 40 for the substrate.

[0140] When the coaxial connector 70 is normally connected to the coaxial connector 40 for the substrate, the central axis X of the coaxial connector 40 for the substrate and the central axis X of the coaxial connector 70 are aligned, and the distance between the coaxial connector 40 for the substrate and the coaxial connector 70 remains at the predetermined design distance (refer to...). Figure 5 ).

[0141] Figure 7 This is a cross-sectional view of the connection structure 28, where the coaxial connector 70 is closest to the coaxial connector 40 for the substrate and the external connection coaxial connector 30 is furthest from the position opposite the coaxial connector 40 for the substrate on the same axis, within the tolerance range. Figure 8 and Figure 9 yes Figure 7 A partial sectional view.

[0142] exist Figure 7 In this design, the distance L2 between the coaxial connector 70 and the coaxial connector 40 on the substrate is smaller than the initial distance L1 by a distance L3. Additionally, the central axis Xa of the coaxial connector 70 is separated from the central axis X of the coaxial connector 40 on the substrate by a distance L4.

[0143] In this case, a portion of the top periphery of the circuit board 21 side of the inner conductor 80 approaches the opposite inner conductor 50. Additionally, a portion of the top periphery of the circuit board 21 side of the outer conductor 90 approaches the opposite outer conductor 60. Therefore, if the top peripheries of the inner conductor cylinder 82 and the outer conductor cylinder 92 still retain their initial shapes without interference-avoiding surfaces, they may come into contact with either the outer conductor 90 or the inner conductor 80 (see reference). Figure 8 and Figure 9 The double-dotted lines indicate parts B1 and B2.

[0144] In this embodiment, since interference avoidance surfaces 83 and 93 are formed in the inner conductor cylinder 82 and the outer conductor cylinder 92 respectively, the top periphery of the inner conductor cylinder 82 and the outer conductor cylinder 92 can be effectively prevented from contacting the outer conductor 90 or the inner conductor 80.

[0145] Furthermore, within tolerance limits, the inner conductor cylinder 82 may be closer to the opposite dielectric body 42. In this case, the top periphery of the inner conductor cylinder 82 can enter the annular recess 47 of the opposite dielectric body 42. This also avoids interference between the inner conductor cylinder 82 and the opposite dielectric body 42.

[0146] It should be noted that, in order to further increase the amount of interference avoidance on surfaces 83 and 93, it is also possible to... Figure 10 The inner conductor cylinder 182 and outer conductor cylinder 192 involved in the modified example shown are similar. That is, slits 183a and 193a along the central axis X are formed in the inner conductor cylinder 182 and outer conductor cylinder 192, respectively. It is sufficient to provide at least one slit 183a and 193a in the inner conductor cylinder 182 and outer conductor cylinder 192, respectively. Multiple slits 183a and 193a may also be provided in the inner conductor cylinder 182 and outer conductor cylinder 192, in which case multiple slits may be provided at equal intervals in the circumferential direction. The number, width, and length of the slits 183a and 193a can be set to a degree that prevents deformation of the inner conductor cylinder 182 and outer conductor cylinder 192 during connection.

[0147] In the inner conductor cylinder 182, the top periphery of the inner conductor cylinder 182 is expanded outwards in a manner that enlarges the slit 183a. The inner periphery of this outwardly expanded portion is formed as an interference avoidance surface 183 corresponding to the interference avoidance surface 83.

[0148] In the outer conductor cylinder 192, the top periphery of the outer conductor cylinder 192 is narrowed inwards by narrowing the slit 193a. The outer periphery of this inwardly narrowed portion is formed as an interference avoidance surface 193 corresponding to the interference avoidance surface 93.

[0149] In these cases, by using slits 183a and 193a, the top periphery of the inner conductor cylinder 182 and the outer conductor cylinder 192 can be expanded outward or narrowed inward, so it is easy to tilt the interference avoidance surfaces 183 and 193 at a large angle and over a wide range, and as a result, it is easy to set the interference avoidance amount to a large value.

[0150] It should be noted that the widths S1 and S2 of the slits 183a and 193a are preferably smaller than the width W1 of the inner elastic piece 56 and the width W3 of the outer elastic piece 66. Therefore, the inner elastic piece 56 and the outer elastic piece 66 will not enter the slits 183a and 193a, but can move smoothly to the inner circumferential surface of the inner conductor cylinder 182 or the outer circumferential surface of the outer conductor cylinder 192.

[0151] <Effects, etc.> According to the coaxial connector 70 and coaxial connector connection structure 28 configured as described above, the portions of the top periphery of the cylindrical portions 82 and 92 that face the opposing inner conductor 50 or the opposing outer conductor 60, which serve as opposing terminals, are inclined away from the opposing inner conductor 50 or the opposing outer conductor 60 as they approach the top of the cylindrical portions 82 and 92. Therefore, even if the top periphery of the cylindrical portions 82 and 92 is close to the opposing inner conductor 50 or the opposing outer conductor 60, contact with the opposing inner conductor 50 or the opposing outer conductor 60 is suppressed. Thus, even if the coaxial connector 70 is inclined relative to the central axis X of the coaxial connector 40 for the substrate, the coaxial connector 70 is less likely to interfere with the coaxial connector 40 for the substrate.

[0152] Furthermore, if interference surfaces 83 and 93 are prevented from extending in a ring shape along the top periphery of the cylindrical portions 82 and 92, then regardless of which direction the coaxial connector 70 is tilted relative to the central axis X of the coaxial connector 40 for the substrate, the coaxial connector 70 is less likely to interfere with the coaxial connector 40 for the substrate.

[0153] Furthermore, if the interference avoidance surfaces 83 and 93 are formed at the position of guiding the inner elastic sheet 56 or the outer elastic sheet 66 at the top periphery of the cylinder 82 and 92, the inner elastic sheet 56 or the outer elastic sheet 66 can be smoothly moved to the inner or outer periphery of the cylinder 82 and 92 by being guided by the interference avoidance surfaces 83 and 93.

[0154] Furthermore, if the inner circumferential portion of the outer conductor cylinder 92 opposite to the interference avoidance surface 93 is formed in a shape where the same diameter portion is continuous along the central axis X of the outer conductor cylinder 92, then the interference avoidance surface 93 can be easily formed by performing chamfering or other processing on the end of the outer conductor cylinder 92.

[0155] Furthermore, if the outer peripheral portion of the inner conductor cylinder 82 opposite to the interference avoidance surface 83 is formed in a shape that is inclined along the interference avoidance surface 83, for example, the interference avoidance surface 83 can be easily formed by bending the end of the inner conductor cylinder 82.

[0156] Furthermore, if slits 83b, 183a, and 193a that divide the interference avoidance surfaces 83, 183, and 193 are formed at the top periphery of the inner conductor cylinder portion 82, 182, or the outer conductor cylinder portion 192, then the divided interference avoidance surfaces 83, 183, and 193 can be easily formed as a whole at the top periphery of the inner conductor cylinder portion 82, 182, or the outer conductor cylinder portion 192.

[0157] In addition, if the widths S1 and S2 of the slits 83b, 183a, and 193a are less than the width W1 of the inner elastic sheet 56 or the width W3 of the outer elastic sheet 66, then the inner elastic sheet 56 or the outer elastic sheet 66 will not be embedded in the slits 83b, 183a, and 193a, but will be smoothly guided to the inner circumference of the inner conductor cylinder 82 and 182 or the outer circumference of the outer conductor cylinder 192.

[0158] Furthermore, since an inner interference avoidance surface 83 is formed in the inner peripheral portion of the top periphery of the inner conductor cylinder 82, even if the inner conductor 80 is tilted significantly relative to the opposite inner conductor 50, the inner peripheral portion of the top periphery of the inner conductor cylinder 82 is not likely to interfere with the opposite inner conductor 50.

[0159] Furthermore, since an outer interference avoidance surface 93 is formed in the outer peripheral portion of the top periphery of the outer conductor cylinder 92, even if the outer conductor 90 is tilted significantly relative to the opposite outer conductor 60, the outer peripheral portion of the top periphery of the outer conductor cylinder 92 is not likely to interfere with the opposite outer conductor 60.

[0160] Furthermore, according to this connection structure 28, the inner conductor 50 on the opposite side has an inner elastic sheet 56, and the outer conductor 60 on the opposite side has an outer elastic sheet 66. Therefore, by elastically deforming the inner elastic sheet 56 and the outer elastic sheet 66, the coaxial connector 70 can be connected to the coaxial connector 40 on the substrate even if the coaxial connector 70 is tilted relative to the coaxial connector 40 on the substrate. In this case, even if the coaxial connector 70 is tilted relative to the coaxial connector 40 on the substrate, interference surfaces 83 and 93 can be avoided, making it less likely for the coaxial connector 70 to interfere with the coaxial connector 40 on the substrate.

[0161] Furthermore, because an annular recess 47 is formed in the dielectric body 42 on the other side, even if the coaxial connector 70 is connected to the coaxial connector 40 for the substrate in an inclined state, the outer conductor tube 92 is not likely to interfere with the dielectric body 42 on the other side.

[0162] Furthermore, because the thickness of the inner and outer circumferences of the opposite side dielectric body 42 can be ensured, the opposite side outer conductor 60 and the opposite side inner conductor 50 are firmly held in the opposite side dielectric body 42.

[0163] It should be noted that the structures described in the above embodiments and variations can be appropriately combined as long as they do not contradict each other. Explanation of reference numerals in the attached figures
