[0009] [Explanation of Embodiments of the Invention] First, an embodiment of the invention will be explained.

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

[0011] (1) A connector provided with a connector conductor, wherein the connector conductor includes a barrel portion and an elastic piece that extends from an opening edge of the barrel portion, the barrel portion has a barrel forming portion that forms a barrel shape, a first end portion in the circumferential direction of the barrel forming portion, a second end portion in the circumferential direction of the barrel forming portion that coincides with the first end portion, and a rivet fixing portion that rivet-fixes the first end portion and the second end portion, and a deformation absorbing opening that penetrates in the radial direction of the barrel portion is formed in the barrel portion.

[0012] It is assumed that the influence of deformation caused by riveting reaches around the rivet fixing portion in the barrel portion when the first end portion and the second end portion are rivet-fixed. In this case, it is possible that the barrel shape of the barrel portion is partially deformed, or the diameter of the barrel portion becomes large. When a deformation absorbing opening is formed in the barrel portion as in this connector, then the influence of deformation caused by riveting is absorbed by the deformation absorbing opening. Therefore, the barrel shape of the barrel portion easily remains in the desired shape. Thus, the support position of the barrel portion to the elastic piece is stable, and a desired contact load is easily obtained when the connector conductor is connected with the counterpart connector.

[0013] (2) In the connector of (1), it is also possible that the barrel forming portion and the first end portion are connected in a manner that forms a barrel shape of the same diameter, the second end portion coincides with the first end portion in the radial direction of the barrel portion, and the deformation absorbing opening is provided at a position closer to the center of the circumferential direction of the barrel forming portion than the position of the rivet fixing portion of the first end portion in the circumferential direction of the barrel portion.

[0014] When the barrel forming portion and the first end portion are connected in a manner that forms a barrel shape of the same diameter, then the influence of riveting on the first end portion is likely to easily reach the barrel forming portion. When the deformation absorbing opening is provided at a position closer to the center of the circumferential direction of the barrel forming portion than the position of the rivet fixing portion of the first end portion, then the influence of riveting on the first end portion does not easily reach the portion close to the second end portion in the barrel forming portion, and the barrel shape of the barrel forming portion easily remains in the desired shape.

[0015] (3) In the connector of (2), the deformation absorbing opening can be located at a boundary between the first end portion and the barrel forming portion in the circumferential direction of the barrel portion.

[0016] Thus, the influence of the riveting on the first end portion is less likely to reach the barrel forming portion, and the barrel shape of the barrel portion is more likely to be maintained as a desired shape.

[0017] (4) In the connector of (2) or (3), the portion of the first end portion on the opening edge side can be continuous with the barrel forming portion.

[0018] In this case, since the portion of the first end portion on the opening edge side is continuous with the barrel forming portion, the elastic piece extending from the opening edge of the barrel forming portion in the vicinity of the first end portion is more likely to be maintained at a certain position.

[0019] (5) In the connector of (4), the elastic piece can include an end portion elastic piece extending from the opening edge at an end portion of the barrel forming portion continuous with the first end portion, the end portion elastic piece having a contact portion contacting the counterpart side conductor, the contact portion being oriented toward one of the inner side and the outer side of the radial direction of the barrel portion, and the second end portion being coincident with the first end portion on a side opposite to the orientation of the contact portion in the radial direction of the barrel portion.

[0020] In this case, the second end portion is coincident with the first end portion on a side opposite to the orientation of the contact portion, and thus the second end portion can receive a force pressing the contact portion against the counterpart side conductor and is more likely to press the contact portion against the counterpart side conductor.

[0021] (6) In the connector of any one of (2) to (5), the second end portion can be coincident with the inner side of the first end portion and protrude inwardly of the barrel forming portion.

[0022] In this way, by making the second end portion protrude inwardly of the barrel forming portion, the second end portion is more likely to be positioned with respect to a member inside the barrel portion.

[0023] (7) In the connector of any one of (2) to (6), the deformation absorbing opening can be formed in a slit-like opening shape.

[0024] In this case, the influence of the deformation caused by the riveting is absorbed in the entire long side direction of the slit-like deformation absorbing opening. Thus, the barrel shape of the barrel portion is more likely to be maintained as a desired shape.

[0025] (8) In the connector of (7), the deformation absorbing opening can extend in a direction intersecting the circumferential direction of the barrel portion.

[0026] Thus, the influence of deformation caused by the caulking is absorbed in the entire long direction of the slit-shaped deformation absorbing opening extending in the direction intersecting the circumference of the cylindrical portion. Therefore, the size of the cylindrical portion or the uniformity of the curvature of the cylindrical shape is not easily affected. The support position of the elastic sheet by the cylindrical portion is stable, and a desired contact load is easily obtained when connecting the connector conductor with the counterpart connector.

[0027] (9) In the connector of (8), it can also be that the deformation absorbing opening extends from the base end side opening edge opposite the opening edge in the cylindrical portion to a position beyond the caulking fixed portion in the direction of the central axis of the cylindrical portion.

[0028] In this case, the deformation absorbing opening extends from the base end side opening edge of the cylindrical portion to a position beyond the caulking fixed portion in the direction of the central axis, so even if the first end portion or the second end portion is deformed by the caulking, the deformation does not easily spread to other portions with the deformation absorbing opening as a boundary. In addition, because the deformation absorbing opening extends to a position beyond the caulking fixed portion, deformation of the first end portion or the second end portion caused by the caulking does not easily spread in the circumferential direction.

[0029] (10) In the connector of any one of (1) to (9), it can also be that an inner conductor is further provided, and an insulator is provided that houses the inner conductor, and the insulator is housed within the cylindrical portion.

[0030] In this case, in the connector having the inner conductor, the insulator that houses the inner conductor, and the connector conductor that is the outer conductor that houses the insulator, the connector conductor and the counterpart conductor can be electrically connected in good condition.

[0031] (11) In the connector of (10), it can also be that a recessed portion is formed in the outer peripheral surface of the insulator, the second end portion is located closer to the inner peripheral side of the cylindrical portion than the first end portion, and the second end portion is embedded in the recessed portion.

[0032] Thus, the outer conductor is easily positioned with respect to the insulator.

[0033] [Details of Embodiments of the Invention] A specific example of the connector of the present invention will be described below with reference to the drawings. Note that the present invention is not limited to these examples, and is shown by the claims, and is intended to include all modifications within the meaning and range equivalent to the claims.

[0034] [Embodiments] The following describes the connector of the embodiment. In the present embodiment, an example in which the connector is a coaxial connector is described. Note that the coaxial connector is a connector in which an outer conductor and an inner conductor inside thereof are located coaxially. The connector is not necessarily a coaxial connector, and may, for example, be a connector in which a plurality of inner conductors are located inside an outer conductor.

[0035] <Overall structure of the device> An example of a device 10 provided with a coaxial connector 60 is described. Figure 1 is a perspective view showing the device 10 provided with the coaxial connector 60. Figure 2 is Figure 1 is a cross-sectional view taken along the line II-II of

[0036] The device 10 is, for example, a camera device. The camera device is, for example, a device for a vehicle. The device 10 can also be other than a camera device.

[0037] The device 10 is provided with a housing 12 and an electrical component 20. The electrical component 20 is housed in the housing 12. The coaxial connector 60 is fixed to the electrical component 20.

[0038] The housing 12 is provided with a first housing 13 and a second housing 14. The first housing 13 and the second housing 14 are formed of, for example, resin. The first housing 13 and the second housing 14 are combined to constitute the housing 12 in the shape of a rectangular parallelepiped that houses the electrical component 20. In the case where the device 10 is a camera device, it is assumed that the first housing 13 has a lens or a window for image pickup, and the second housing 14 has an external connection coaxial connector 30.

[0039] The external connection coaxial connector 30 is a coaxial connector for connecting the electrical component 20 and an electrical component outside. For example, the external connection coaxial connector 30 is a coaxial connector to which a cable connected to an electrical component outside is connected. The cable connected to the external connection coaxial connector 30 is, for example, a coaxial cable.

[0040] More specifically, a holding cylinder portion 16 is provided protruding from a bottom portion 15 of the housing 12. The holding cylinder portion 16 is a cylinder that protrudes outward from a central portion of the bottom portion 15. The inner side of the holding cylinder portion 16 is open in the second housing 14, and the outer side of the holding cylinder portion 16 is open outside the second housing 14. A holding partition portion 17 is formed at an intermediate portion of the holding cylinder portion 16 in the direction along the central axis X (axial direction). In the present embodiment, the holding partition portion 17 is formed at an intermediate portion of the holding cylinder portion 16 in the direction along the central axis X and close to the inner side opening. The holding partition portion 17 separates the space on the inner side opening side and the space on the outer side opening side in the holding cylinder portion 16. A holding hole 17h is formed in the holding partition portion 17, and the external connection coaxial connector 30 is inserted into the holding hole 17h.

[0041] In the present embodiment, a locking protrusion 18a is formed in the outer peripheral portion of the holding cylinder portion 16, and is used to hold a cable connector fitted to the end portion of a cable. It is not necessary to form the locking protrusion 18a.

[0042] The external connection coaxial connector 30 is provided with an external connection inner conductor 32, an external connection insulator 34, and an external connection outer conductor 36.

[0043] The external connection inner conductor 32 is formed in an elongated rod shape, and is formed of an electrically conductive material such as metal. The external connection insulator 34 is formed of an insulator such as resin, and surrounds the periphery of the external connection inner conductor 32. In the present embodiment, the external connection insulator 34 is a dielectric body. The external connection outer conductor 36 is formed of an electrically conductive material such as metal. The external connection outer conductor 36 is formed in a cylindrical shape that surrounds the periphery of the external connection insulator 34.

[0044] The electrical component 20 is, for example, a mounting substrate on which an electronic component is mounted. In the case where the device 10 is a camera device, it is assumed that the electrical component 20 is a circuit substrate 21 and an imaging element 22 mounted to the circuit substrate 21. The imaging element 22 opposes a lens or a window for imaging of the first housing 13, and rotates the lens or the window to perform imaging of the outside scenery. Hereinafter, the side of the first housing 13 toward which the imaging element 22 faces will be referred to as the front side, and the side of the second housing 14 opposite thereto will be referred to as the rear side.

[0045] In the present embodiment, the coaxial connector 60 is located in the face of the circuit substrate 21 on the side opposite the imaging element 22. The coaxial connector 60 is fixed to the circuit substrate 21, and protrudes from the circuit substrate 21 toward the above-described external connection coaxial connector 30. The coaxial connector 60 is a substrate side coaxial connector. The coaxial connector 60 is provided with, for example, an inner conductor 62, an insulator 70, and an outer conductor 80. The inner conductor 62 is connected to the movable side inner conductor 42 described below. The insulator 70 surrounds the periphery of the inner conductor 62. The outer conductor 80 surrounds the periphery of the insulator 70. That is, the inner conductor 62, the insulator 70, and the outer conductor 80 are arranged in a concentric circular shape in that order from the center toward the outer peripheral side.

[0046] The coaxial connector 60 and the external connection coaxial connector 30 are connected via the relay connector 40. The relay connector 40 has, for example, a movable-side inner conductor 42, a movable-side insulator 44, and a movable-side outer conductor 46. The movable-side insulator 44 surrounds the movable-side inner conductor 42. In the present embodiment, the movable-side insulator 44 is a dielectric body. The movable-side outer conductor 46 surrounds the movable-side insulator 44. The movable-side inner conductor 42 is an example of an opposite-side inner conductor to be connected to the inner conductor 62, the movable-side outer conductor 46 is an example of an opposite-side outer conductor to be connected to the outer conductor 80, and the relay connector 40 is an example of an opposite-side coaxial connector to be connected to the coaxial connector 60.

[0047] The relay connector 40 is connected to the coaxial connector 60 in a state in which the movable-side inner conductor 42 is inserted and connected to the inner conductor 62, and the outer conductor 80 is inserted and connected to the movable-side outer conductor 46. In this state, the relay connector 40 further protrudes from the coaxial connector 60 toward the external connection coaxial connector 30. The relay connector 40 is connected to the external connection coaxial connector 30 by the external connection inner conductor 32 being inserted and connected to the movable-side inner conductor 42, and the movable-side outer conductor 46 being inserted and connected to the external connection outer conductor 36. Thus, the relay connector 40 relays the connection between the coaxial connector 60 and the external connection coaxial connector 30.

[0048] Thus, by connecting a cable from the outside to the external connection coaxial connector 30, the electrical component of the outside that is a connection opposite of the cable and the electrical component 20 in the housing 12 are electrically connected.

[0049] In the connected state of the above-described relay connector 40 and the coaxial connector 60, the movable-side inner conductor 42 is inserted and connected to the inner conductor 62 in an inclined state. Also, the outer conductor 80 is inserted and connected to the movable-side outer conductor 46 in an inclined state. That is, the relay connector 40 can be connected to the coaxial connector 60 in an inclined state (see arrow P1 in FIG. 10). Thus, at the time of assembly work of the present device 10 or in the completed state, even if the coaxial connector 60 and the external connection coaxial connector 30 are deviated from the positions that are opposed on the coaxial axis (see arrow P2 in FIG. 10), but by the relay connector 40 being inclined with respect to the coaxial connector 60, the positional deviation can be absorbed. Figure 2 Figure 2

[0050] <Regarding the Coaxial Connector> The coaxial connector 60 will be described in detail. Figure 3 is a perspective view showing the coaxial connector 60. Figure 4 is an exploded perspective view showing the coaxial connector 60. Figure 5 is a bottom view showing the coaxial connector 60.

[0051] ​​As described above, the coaxial connector 60 is provided with, for example, the inner conductor 62, the insulator 70, and the outer conductor 80.

[0052] The inner conductor 62 is an elongated electrically conductive member (see Figure 2 and Figure 4 ). In the present embodiment, the inner conductor 62 is formed by press working a metal plate. More specifically, the inner conductor 62 includes a base end cylindrical portion 64 and a plurality of elastic pieces 66.

[0053] The base end cylindrical portion 64 is formed in a cylindrical shape, more specifically, a circular cylindrical shape. The base end cylindrical portion 64 is housed in the base end side of the insulator 70. Note that, in the coaxial connector 60, the so-called top end is the end on the side to which the movable side inner conductor 42 is connected, and the base end is the end on the side opposite to the top end, which is the end on the side toward the circuit board 21.

[0054] An extension piece 64a is extended from the base end side edge of the base end cylindrical portion 64 toward the inside of the base end cylindrical portion 64. The extension piece 64a is, for example, soldered to the circuit of the circuit board 21.

[0055] The base end cylindrical portion 64 can also have a positioning protrusion 64P that partially protrudes toward the outer peripheral side in the circumferential direction. The positioning of the inner conductor 62 with respect to the insulator 70 can be performed by fitting the positioning protrusion 64P into a recess in the insulator 70.

[0056] A locking protrusion 64b is provided protruding from the base end cylindrical portion 64. The locking protrusion 64b partially protrudes from the outer peripheral portion of the base end cylindrical portion 64. The locking protrusion 64b is formed in a shape in which the protruding dimension gradually increases from the top end of the base end cylindrical portion 64 toward the base end. In a state in which the base end cylindrical portion 64 is inserted into the insulator 70, the locking protrusion 64b is hooked to the inner peripheral portion of the insulator 70, and the inner conductor 62 is held by the insulator 70 in a state in which it is prevented from coming off.

[0057] The plurality of elastic pieces 66 protrude further toward the top end side from the top end side opening of the base end cylindrical portion 64. Preferably, the plurality of elastic pieces 66 are positioned at equal intervals around the central axis X of the cylindrical portion 72. In the present embodiment, two elastic pieces 66 are opposed around the central axis X of the base end cylindrical portion 64.

[0058] The movable side inner conductor 42 of the relay connector 40 is inserted from the top end side of the two elastic pieces 66 toward between the two elastic pieces 66. The movable side inner conductor 42 becomes a state in which it is sandwiched by the two elastic pieces 66, and thus the movable side inner conductor 42 is connected to the inner conductor 62.

[0059] The insulator 70 is formed of resin or the like. The insulator 70 is also a dielectric body, which can be one kind of insulator. The insulator 70 is, for example, a mold-formed resin member.

[0060] The insulator 70 has a cylindrical portion 72 and a tip guide portion 76.

[0061] The cylindrical portion 72 is formed in a cylindrical shape so as to accommodate the inner conductor 62. In the present embodiment, the cylindrical portion 72 is formed in a circular cylindrical shape, and a circular cylindrical space is formed in the inside thereof. The inner conductor is accommodated in the circular cylindrical space.

[0062] The outer peripheral surface of the cylindrical portion 72 is formed in a circumferential surface shape centered on the central axis X. The outer conductor 80 is arranged on the outer peripheral side of the cylindrical portion 72. A recessed portion 72g for positioning is formed in a part of the circumferential direction of the outer peripheral portion of the cylindrical portion 72. The recessed portion 72g has a pair of side surfaces 72gl facing each other in the circumferential direction of the cylindrical portion 72 and a surface 72g2 facing the base end side of the cylindrical portion 72 (see FIG. 6). The second end portion 88 described later is fitted into the recessed portion 72g. In this state, the second end portion 88 is positionally restricted by the pair of side surfaces 72gl and the surface 72g2. Thus, the outer conductor 80 that is fitted to the outside of the insulator 70 is restricted from rotating around the central axis X and moving toward the tip end side with respect to the insulator 70. Figure 4 ) The second end portion 88 described later is fitted into the recessed portion 72g. In this state, the second end portion 88 is positionally restricted by the pair of side surfaces 72gl and the surface 72g2. Thus, the outer conductor 80 that is fitted to the outside of the insulator 70 is restricted from rotating around the central axis X and moving toward the tip end side with respect to the insulator 70.

[0063] A plurality of (four in this case) elongated protrusions 72a are formed in the outer peripheral surface of the cylindrical portion 72. Each of the protrusions 72a extends in parallel with the central axis X. The plurality of protrusions 72a are preferably positioned at equal intervals in the outer peripheral surface of the cylindrical portion 72 around the central axis X. The protrusions 72a contact the inner peripheral surface of the cylindrical portion 82 at positions dispersed in the circumferential direction. A stop portion 82P that is stopped by the insulator 70 can also be formed in the cylindrical portion 82.

[0064] The tip guide portion 76 is located on the tip end side of the cylindrical portion 72. The tip guide portion 76 has an insertion hole 77 into which the movable-side inner conductor 42 can be inserted. The central axis X of the cylindrical portion 72 coincides with the central axis X of the insertion hole 77.

[0065] The inner peripheral surface of the insertion hole 77 is formed in a tapered shape that gradually narrows toward the inside of the cylindrical portion 72. The tip end portion of the movable-side inner conductor 42 is guided toward between the plurality of elastic pieces 66 by the tapered inner peripheral surface of the insertion hole 77.

[0066] In addition, the outer peripheral portion of the tip guide portion 76 protrudes outwardly of the cylindrical portion 72. An outer peripheral side guide surface 78 that gradually widens toward the base end side is formed in the outer peripheral portion of the tip guide portion 76. The outer peripheral side guide surface 78 functions to guide the cylindrical shape portion of the movable-side outer conductor 46 outwardly of the outer conductor 80.

[0067] The annular back surface in the tip guide portion 76 that faces the base end side extends in a manner orthogonal to the central axis X of the cylindrical portion 72. The elastic pieces 90, 96 described later can be elastically deformed in the radial direction of the cylindrical portion 72 on the base end side of the annular back surface.

[0068] The outer conductor 80 is formed of an electrically conductive material such as metal, and surrounds the circumference of the insulator 70. The outer conductor 80 is formed, for example, by press working a metal plate or the like.

[0069] The outer conductor 80 has a cylindrical portion 82 and elastic pieces 90, 96. In the present embodiment, the outer conductor 80 has an end elastic piece 90 and additional elastic pieces 96 as the elastic pieces.

[0070] The cylindrical portion 82 is formed in a cylindrical shape that can accommodate the cylindrical portion 72 inside. The end elastic piece 90 and at least one additional elastic piece 96 project from an opening edge on the tip side in the cylindrical portion 82. The end elastic piece 90 and at least one additional elastic piece 96 are arranged at intervals in the circumferential direction of the cylindrical portion 82. In the present embodiment, the end elastic piece 90 is one, and the additional elastic pieces 96 are seven. These end elastic piece 90 and at least one additional elastic piece 96 are arranged at equal intervals in the circumferential direction of the cylindrical portion 82.

[0071] In a state in which the base end portion of the insulator 70 is accommodated inside the cylindrical portion 82, these end elastic piece 90 and at least one additional elastic piece 96 surround the circumference of the cylindrical portion 72 between the tip guide portion 76 and the cylindrical portion 82.

[0072] The movable-side outer conductor 46 of the relay connector 40 is guided toward the outer peripheral side of the end elastic piece 90 and the additional elastic pieces 96 by the outer peripheral side guide surface 78 of the tip guide portion 76. Thereby, the end elastic piece 90 and the additional elastic pieces 96 come into contact with the movable-side outer conductor 46 from the inner peripheral side, and the outer conductor 80 and the movable-side outer conductor 46 are connected.

[0073] <Concerning the Outer Conductor> The outer conductor 80, which is an example of a connector conductor, will be described in more detail. Figure 6 is a perspective view showing the outer conductor 80. Figure 7 is Figure 5 is a partial cross-sectional view of the VII-VII line of

[0074] As shown in Figures 3 to 7 , the outer conductor 80 has a cylindrical portion 82 and an end elastic piece 90 and additional elastic pieces 96 that project from an opening edge on the tip side of the cylindrical portion 82.

[0075] The cylindrical portion 82 is a portion that is fitted outside the insulator 70. The cylindrical portion 82 is held in a certain position with respect to the insulator 70, and functions to support the outer conductor 80 in a certain position with respect to the insulator 70. In addition, for example, if the base end side opening of the cylindrical portion 82 is soldered to a circuit, such as a ground circuit, of the circuit board 21, it can function to ground the movable-side outer conductor 46 to the ground circuit.

[0076] The cylindrical portion 82 has a first end portion 84, a cylindrical forming portion 86, and a second end portion 88.

[0077] The cylinder forming portion 86 forms a cylindrical shape. The first end portion 84 is connected to one end side in the circumferential direction of the cylinder forming portion 86. In the present embodiment, the cylinder forming portion 86 forms a cylindrical shape of one turn. In addition, the cylinder forming portion 86 also forms a cylindrical shape of one turn in a state connected to the first end portion 84.

[0078] In the present embodiment, the width of one end portion of the cylinder forming portion 86 is formed to be narrower than the other end portion in the direction of the central axis X. More specifically, the one end portion of the cylinder forming portion 86 extends in the circumferential direction only on the side on which the end elastic piece 90 protrudes (the opening edge side). Thus, the one end portion of the cylinder forming portion 86 is formed into a shape that is cut into a square shape on the side opposite to the side on which the end elastic piece 90 protrudes (the opening edge side).

[0079] The first end portion 84 is connected to the one end portion of the cylinder forming portion 86 on the side opposite to the side on which the end elastic piece 90 protrudes (the opening edge side) and protrudes toward the side opposite to the side on which the end elastic piece 90 protrudes (the opening edge side). That is, the portion of the opening edge side in the first end portion 84 is connected to the one end portion of the cylinder forming portion 86. Thus, in a state in which the cylinder forming portion 86 and the first end portion 84 form a cylindrical shape of one turn, the one end portion of the cylinder forming portion 86 and the first end portion 84 can be opposed to the other end portion of the cylinder forming portion 86 in the circumferential direction of the cylinder portion 82.

[0080] The second end portion 88 is connected to the cylinder forming portion 86 on the side opposite to the first end portion 84. The second end portion 88 is the other end portion in the circumferential direction of the cylinder forming portion 86. The second end portion 88 coincides with the first end portion 84 in the radial direction of the cylinder portion 82. That is, the first end portion 84, the cylinder forming portion 86, and the second end portion 88 are formed into a shape of a cylindrical shape of more than one turn, and the both end portions of the cylinder portion 82 coincide with each other corresponding to the more than one turn. One of the coinciding portions is the first end portion 84, and the other is the second end portion 88.

[0081] In the present embodiment, the second end portion 88 protrudes from the portion near the side opposite to the side on which the elastic pieces 90, 96 protrude in the circumferential direction with respect to the other end portion of the cylinder forming portion 86. The width of the first end portion 84 and the second end portion 88 are set to be the same in the direction of the central axis X of the cylinder portion 82. Thus, the second end portion 88 can overlap the first end portion 84. In this state, the second end portion 88 does not coincide with the one end portion 82e of the cylinder portion 82, and the one end portion 82e of the cylinder portion 82 is exposed on the inner circumferential side of the cylinder portion 82.

[0082] The second end portion 88 can overlap the first end portion 84 on the inner circumferential side or on the outer circumferential side. The second end portion 88 is preferably coincided with the first end portion 84 on the side opposite to the direction of the contact portion 93a. In the present embodiment, as described later, the contact portion 93a faces the outer circumferential side. Thus, the second end portion 88 overlaps the inner circumferential side of the first end portion 84.

[0083] In contrast to the above, in a case where the elastic piece contacts the counterpart conductor from the outer peripheral side, that is, in a case where the contact portion is directed toward the inner peripheral side, it is preferable that the second end portion overlap the first end portion on the outer peripheral side.

[0084] In the present embodiment, the first end portion 84 and the cylindrical forming portion 86 are connected in a manner to form a cylindrical shape of the same diameter. That is, the first end portion 84 and the cylindrical forming portion 86 are formed in a shape that forms the same radius of curvature with the center axis X as the center. The second end portion 88 coincides with the inner side of the first end portion 84 and protrudes more inward than the cylindrical forming portion 86. More specifically, one end portion 82e of the cylindrical forming portion 86 and the first end portion 84 trace the same arc when viewed in the direction of the center axis X. A step portion 87 is formed between the cylindrical forming portion 86 and the second end portion 88. The step of the step portion 87 is set to, for example, the thickness of the cylindrical portion 82. The second end portion 88 protrudes more inward than the cylindrical forming portion 86 via this step portion 87. The second end portion 88 protrudes by the thickness of the cylindrical portion 82 toward the inner peripheral side with respect to the first end portion 84 and the cylindrical forming portion 86.

[0085] In a state where the cylindrical portion 72 of the insulator 70 is housed in the cylindrical portion 82, the second end portion 88 is fitted into the positioning recessed portion 72g of the cylindrical portion 72. In this state, in a range where the second end portion 88 contacts either one of a pair of side surfaces 72gl of the recessed portion 72g, the rotation of the outer conductor 80 with respect to the insulator 70 is stopped. The width of the recessed portion 72g in the outer peripheral direction of the insulator 70 can be the same as the width of the second end portion 88 in the same direction, or can be different. By the second end portion 88 contacting the surface 72g2 of the recessed portion 72g, the excessive insertion of the cylindrical portion 72 of the insulator 70 into the cylindrical portion 82 of the outer conductor 80 is suppressed.

[0086] The cylindrical portion 82 also has a rivet fixing portion 83. The rivet fixing portion 83 is a portion that rivet-fixes the coinciding first end portion 84 and the second end portion 88. The rivet fixing portion 83 holds the first end portion 84 and the second end portion 88 in a coinciding state by plastic deformation of at least one of the first end portion 84 and the second end portion 88.

[0087] In the present embodiment, a protrusion 83a is formed in one of the first end portion 84 and the second end portion 88 by plastic deformation, and a recess 83b is formed in the other by plastic deformation. By the protrusion 83a and the recess 83b fitting into each other, the first end portion 84 and the second end portion 88 are held in a coinciding state.

[0088] More specifically, for example, the coinciding first end portion 84 and second end portion 88 are pressed between a punch having a convex portion and a die having a concave portion. Then, a part of the first end portion 84 and the second end portion 88 are pressed against each other from the convex portion of the punch toward the concave portion of the die. The convex portion 83a and the concave portion 83b (refer to Figure 7 ) are simultaneously press-formed into the first end portion 84 and the second end portion 88. For example, the convex portion of the punch is pressed against the outer peripheral surface of the first end portion 84, and the concave portion of the punch is disposed on the inner peripheral surface of the second end portion 88. By the press working, the convex portion 83a projecting toward the inner peripheral side is formed in the first end portion 84. In addition, the concave portion 83b is formed on the outer peripheral surface of the second end portion 88. The convex portion 83a of the first end portion 84 is embedded in the concave portion 83b of the second end portion 88, and the first end portion 84 and the second end portion 88 are held in the coinciding state.

[0089] Such a joining structure can also be a structure called point riveting or a structure called draw lock, for example.

[0090] The cylindrical portion 82 is formed with a deformation absorbing opening 82S penetrating in the radial direction of the cylindrical portion 82. The deformation absorbing opening 82S is an opening for absorbing the influence of the deformation caused by the riveting at the time of forming the rivet fixing portion 83. For example, when the first end portion 84 is compressed by the riveting process, the first end portion 84 can be deformed in an elongated manner by the compression. If this deformation reaches the entire cylindrical portion 82, the cylindrical shape of the cylindrical portion 82 can be deformed, or the diameter of the cylindrical portion 82 can be larger than the designed value. The deformation absorbing opening 82S is an opening for absorbing the deformation caused by the riveting so that the influence of the deformation caused by the riveting does not reach the entire cylindrical portion 82. The deformation absorbing opening 82S preferably has a space of a degree that can accommodate a deformation reaching portion that is elongated or displaced by the local deformation of the cylindrical portion 82.

[0091] The deformation absorbing opening 82S can be formed at any position in the cylindrical portion 82. This is because, regardless of the position at which the deformation absorbing opening 82S is formed in the cylindrical portion 82, the deformed portion is disposed within the deformation absorbing opening, and the deformation from the deformation causing portion in the cylindrical portion 82 can be inhibited from reaching other portions.

[0092] Preferably, as described in the present embodiment, the deformation absorbing opening 82S is provided at a position closer to the center M (refer to Figure 6 ) of the circumferential direction of the tube forming portion 86 than the position of the rivet fixing portion 83 of the first end portion 84. Thus, the deformation caused by the rivet fixing portion 83 of the first end portion 84 can be inhibited from reaching the other end side of the tube forming portion 86. Thus, the cylindrical shape of the cylindrical portion 82 is easily maintained as the predetermined shape without deformation.

[0093] More preferably, as explained in the present embodiment, the deformation absorbing opening 82S is located at the boundary of the first end portion 84 and the tubular portion 82 in the circumferential direction of the tubular portion 82. Thus, the influence of the riveting on the first end portion 84 is less likely to reach the tubular forming portion 86. As a result, the tubular forming portion 86 is easily maintained in the initial cylindrical shape, and the tubular shape of the tubular portion 82 is easily maintained in the predetermined shape without deformation.

[0094] The deformation absorbing opening can also be formed at a position different from the above. For example, the deformation absorbing opening can be formed at a position in the first end portion 84 overlapping the second end portion 88, or at a position in the tubular forming portion 86 not overlapping the second end portion 88. Also, for example, the deformation absorbing opening can be located closer to the circumferential center of the tubular forming portion 86 than the riveting fixing portion 83 of the first end portion 84. Also, the deformation absorbing opening can be located at the boundary of the second end portion and the tubular forming portion 86 in the circumferential direction of the tubular portion 82. Also, the deformation absorbing opening can be located between the riveting fixing portion 83 and the elastic pieces 90, 96 in the direction of the central axis X of the tubular portion 82.

[0095] Also, the deformation absorbing opening 82S only needs to have a space of a degree that can accommodate the deformation reaching portion, and the shape thereof is not particularly limited. The deformation absorbing opening can be, for example, a slit-like opening having a width, or a through opening of a circular, elliptical, or polygonal shape. A plurality of deformation absorbing openings can also be formed in the tubular portion 82. In this case, the plurality of deformation absorbing openings can be arranged in a straight line at intervals, or can be arranged in a scattered manner.

[0096] In the present embodiment, the deformation absorbing opening 82S is formed in a slit-like opening shape. The deformation absorbing opening 82S has a pair of inner surfaces along the long direction thereof, which are opposed to each other at intervals. A space that can accommodate the deformation reaching portion is formed between the pair of inner surfaces.

[0097] The deformation absorbing opening 82S preferably extends in a direction intersecting the circumferential direction of the tubular portion 82. In the present embodiment, the deformation absorbing opening 82S extends in the direction of the central axis X of the tubular portion 82. Thus, the influence of the deformation reaching portion generated by the riveting fixing portion 83 is absorbed in the long direction of the deformation absorbing opening 82S extending in the direction intersecting the circumferential direction of the tubular portion 82 as a whole. As a result, the influence of the deformation reaching portion is less likely to reach the tubular forming portion 86. Note that the deformation absorbing opening 82S can extend in an inclined direction with respect to the direction of the central axis X, or can extend while being bent in the middle.

[0098] Further, the deformation absorbing opening 82S is preferably extended from the base end side opening edge in the cylindrical portion 82 to a position beyond the rivet fixing portion 83 in the direction of the central axis X. Note that the base end side opening edge is the opening edge on the side opposite to the opening edge from which the elastic pieces 90, 96 extend in the cylindrical portion 82.

[0099] The elongation deformation of the first end portion 84 occurs centered on the rivet fixing portion 83. Therefore, the cylindrical portion 82 is considered to be deformed or change in diameter centered on the position of the rivet fixing portion 83 in the direction of the central axis X. When the deformation absorbing opening 82S is extended from the base end side opening edge of the cylindrical portion 82 to a position beyond the rivet fixing portion 83 in the direction of the central axis X, the influence of the elongation deformation of the rivet fixing portion 83 is less likely to reach the circumferential direction of the cylindrical portion 82. Note that the deformation absorbing opening can also be a length that does not extend beyond the rivet fixing portion 83 in the direction of the central axis X.

[0100] The outer conductor 80 includes the end portion elastic piece 90 and the additional elastic piece 96 as elastic pieces.

[0101] The end portion elastic piece 90 extends from the opening edge in the end portion of the cylindrical portion 86 connected to the first end portion 84, i.e., the aforementioned one end portion 82e.

[0102] The end portion elastic piece 90 is a portion that extends from the opening edge on one side of the cylindrical portion 82 and is connected to the movable side outer conductor 46 as the counterpart side terminal.

[0103] That is, on the opening edge side of the cylindrical portion 82, the cylindrical portion 86 forms a cylindrical shape of one turn, and at least a portion of the end portion elastic piece 90 extends from the opening edge in the one end portion 82e of the cylindrical portion 86 to the side of the direction of the central axis X.

[0104] As long as at least a portion of the base end portion of the end portion elastic piece 90 is connected to the one end portion 82e of the cylindrical portion 86. In the present embodiment, the first end portion 84 and the second end portion 88 overlap each other in a region of half or less of the width of the end portion elastic piece 90. Therefore, the one end portion 82e of the cylindrical portion 86 connected to the first end portion 84 is connected to the end portion elastic piece 90 at half or less of the width direction of the base end portion of the end portion elastic piece 90. The end portion elastic piece 90 can also be connected to the one end portion at a greater width.

[0105] The end portion elastic piece 90 has an inclined portion 92, a bulging portion 93, and a tip guide portion 94. The inclined portion 92, the bulging portion 93, and the tip guide portion 94 are connected in this order from the cylindrical portion 82 to the side of the central axis X of the cylindrical portion 82.

[0106] The inclined portion 92 is a plate-shaped portion directly connected to the one end portion 82e and is a plate-shaped portion spaced apart from the adjacent additional elastic piece 96. The inclined portion 92 extends in a manner inclined from the one end portion 82e toward the central axis X (in this case, inclined toward the outer peripheral side). Thus, the end portion elastic piece 90 is elastically deformable mainly in the inner and outer directions of the cylindrical portion 82 at the top end side portion from the boundary of the one end portion 82e and the inclined portion 92.

[0107] The bulging portion 93 forms a curved surface bulging outward from the top end of the inclined portion 92 and toward one side of the central axis X. The portion protruding most outward in the peripheral direction in the bulging portion 93 is a contact portion 93a that is directed outward in the radial direction of the cylindrical portion 82 and contacts the movable-side outer conductor 46.

[0108] The top end guide portion 76 is inclined from the top end of the bulging portion 93 toward the inner peripheral side of one side of the central axis X.

[0109] When the outer conductor 80 is inserted into the movable-side outer conductor 46, the end portion elastic piece 90 is guided toward the inner peripheral side of the movable-side outer conductor 46 by the contact of the top end guide portion 76 with the opening rim of the movable-side outer conductor 46. In the state in which the outer conductor 80 is inserted into the movable-side outer conductor 46, mainly the inclined portion 92 is elastically deformed toward the inner peripheral side. The contact portion 93a is elastically pressed to the inner peripheral surface of the movable-side outer conductor 46 by the elastic force with which the inclined portion 92 returns to the original shape. In this state, a force toward the inner peripheral side acts on the inclined portion 92 of the end portion elastic piece 90. Thus, it is desirable to firmly support the one end portion 82e that supports the inclined portion 92 so as not to be displaced toward the inner peripheral side.

[0110] In the present embodiment, the second end portion 88 overlaps the first end portion 84 connected to the one end portion 82e on the inner side. Thus, the first end portion 84 is firmly supported by the second end portion 88 so as not to be displaced toward the inner peripheral side, and the one end portion 82e connected to the first end portion 84 is also firmly supported so as not to be displaced toward the inner peripheral side.

[0111] The above-described second end portion 88 protrudes toward the inner peripheral side more than the first end portion 84 and the cylindrical forming portion 86. In the state in which the cylindrical portion 72 of the insulator 70 is accommodated in the cylindrical portion 82, the second end portion 88 is fitted into the positioning recessed portion 72g of the cylindrical portion 72. In this state, the rotation of the outer conductor 80 relative to the insulator 70 is regulated in a range in which the second end portion 88 contacts either one of a pair of side surfaces 72gl of the recessed portion 72g.

[0112] Further, the face of the second end portion 88 on the side of the end portion elastic piece 90 is brought into contact with the face 72g2 of the recessed portion 72g, thereby suppressing the excessive insertion of the cylindrical portion 72 of the insulator 70 into the cylindrical portion 82 of the outer conductor 80.

[0113] The bottom face 72gb of the recessed portion 72g is preferably formed at a position that blocks the displacement of the second end portion 88 toward the inner peripheral side.

[0114] In the present embodiment, the bottom surface 72gb is formed as a surface parallel to the central axis X. In a state where the second end portion 88 is disposed in the recessed portion 72g, the inner peripheral side portion of the second end portion 88 is in contact with or opposed to the bottom surface 72gb with a gap. Thus, the bottom surface 72gb can block the second end portion 88 from being displaced toward the inner peripheral side.

[0115] The bottom surface 72gb and the second end portion 88 are not necessarily in contact. For example, a gap of 1 mm or less can be formed between the bottom surface 72gb and the second end portion 88, and the bottom surface 72gb can be configured to block the second end portion 88 from being displaced toward the inner peripheral side by the second end portion 88 being in contact with the bottom surface 72gb by being displaced toward the inner peripheral side.

[0116] As described above, the outer conductor 80 further includes at least one additional elastic piece 96 extending from the opening edge of the cylindrical portion 82. In the present embodiment, the outer conductor 80 includes a plurality of additional elastic pieces 96, specifically, seven additional elastic pieces 96. That is, the outer conductor 80 includes a plurality of elastic pieces 90, 96, more specifically, eight elastic pieces 90, 96.

[0117] The additional elastic pieces 96 are formed in the same shape as the end elastic pieces 90 except for the portions supported by the cylindrical portion 82.

[0118] The plurality of elastic pieces 90, 96 are supported so as to be arranged at equal intervals in the circumferential direction of the cylindrical portion 82. Note that the so-called equal intervals include the same within a range of error (for example, the same within a range of ±5 degrees around the central axis X). When viewed along the central axis X of the cylindrical portion 82, the plurality of elastic pieces 90, 96 are arranged radially around the central axis X of the cylindrical portion 82.

[0119] In a state where the outer conductor 80 is inserted into the movable-side outer conductor 46, the plurality of elastic pieces 90, 96 are in contact with the inner peripheral portion of the movable-side outer conductor 46 at equal intervals in the circumferential direction thereof. Since the plurality of elastic pieces 90, 96 are of the same shape and arranged at equal intervals in the circumferential direction of the cylindrical portion 82, the plurality of elastic pieces 90, 96 are pressed to the movable-side outer conductor 46 under the same conditions. In addition, in a case where the plurality of elastic pieces are supported by a slitted cylindrical member, since the cylindrical member can be elastically deformed in the inward and outward directions around the slits, the force supporting the elastic pieces becomes weak, and the elastic force with which the elastic pieces are pressed to the counterpart conductor can become weak. In the present embodiment, since the first end portion 84 is supported by the second end portion 88, it is easy to support the base end of the end elastic piece 90 at a certain position, and thus it is easy to maintain a state where the end elastic piece 90 is pressed to the movable-side outer conductor 46 at a desired design contact load.

[0120] In addition, the influence of the riveting of the rivet fixing portion 83 is absorbed by the deformation absorbing opening 82S, and is not easily transmitted to other portions. Therefore, the cylindrical shape of the cylindrical portion 82 is not easily partially deformed, or the size of the cylinder is not easily increased, and the cylindrical portion 82 easily maintains the predetermined cylindrical shape. Thus, the plurality of elastic pieces 90, 96 are easily pressed to the movable-side outer conductor 46 under the same conditions.

[0121] <Effects, etc.> According to the coaxial connector 60 configured as described above, when the first end portion 84 and the second end portion 88 are rivet-fixed, it is assumed that the influence of the deformation caused by the riveting is transmitted to the vicinity of the rivet fixing portion 83 in the cylindrical portion 82. In this case, it is possible that the cylindrical shape of the cylindrical portion 82 is partially deformed, or the diameter of the cylindrical portion 82 is increased. When the deformation absorbing opening 82S is formed in the cylindrical portion 82, the deformation transmission portion caused by the riveting is disposed in the deformation absorbing opening 82S, and the transmission of the influence of the deformation is suppressed with the deformation absorbing opening 82S as a boundary. Therefore, the cylindrical shape of the cylindrical portion 82 is easily maintained as a desired shape. Thus, the support position of the cylindrical portion 82 to the elastic pieces 90, 96 is stabilized, the elastic pieces 90, 96 are easily and firmly maintained at a certain position suitable for connection with the counterpart movable-side outer conductor 46, and a desired contact load is easily obtained. In addition, the deformation transmission portion of the rivet fixing portion 83 is not easily transmitted to the cylindrical portion 82, and thus the deformation amount of the rivet fixing portion 83 can be increased, and the first end portion 84 and the second end portion 88 are firmly fixed.

[0122] In addition, if the first end portion 84 and the second end portion 88 are fixed by the rivet fixing portion 83, the outer conductor 80 can be manufactured at a low cost compared to the case where the connector conductor is formed by cutting processing or welding processing of a plate.

[0123] In addition, when the cylindrical forming portion 86 and the first end portion 84 are connected in a manner that the same diameter cylindrical shape is formed, the influence of the riveting on the first end portion 84 can be easily transmitted to the cylindrical forming portion 86. When the deformation absorbing opening 82S is provided at a position closer to the central portion M in the circumferential direction of the cylindrical forming portion 86 than the position of the rivet fixing portion 83 of the first end portion 84 in the circumferential direction of the cylindrical portion 82, the influence of the riveting on the first end portion 84 is not easily transmitted to the second end portion 88 side in the cylindrical forming portion 86, and the cylindrical shape of the cylindrical forming portion 86 is easily maintained as a desired shape.

[0124] In addition, when the deformation absorbing opening 82S is formed at the boundary of the first end portion 84 and the cylindrical forming portion 86, the influence of the riveting on the first end portion 84 is more not easily transmitted to the cylindrical forming portion 86, and the cylindrical shape of the cylindrical forming portion 86 is more easily maintained as a desired shape.

[0125] In addition, since the first end portion 84 is connected to the one end portion 82e of the tube forming portion 86 on the opening edge side, the end portion elastic piece 90 extending from the opening edge of the tube forming portion 86 in the vicinity of the first end portion 84 is easily held in position.

[0126] In addition, the second end portion 88 coincides with the first end portion 84 on the side opposite the direction of the contact portion 93a. Therefore, the second end portion 88 can receive the force that presses the contact portion 93a against the movable side outer conductor 46, and easily presses the contact portion 93a against the movable side outer conductor 46.

[0127] In addition, since the second end portion 88 protrudes toward the inner circumferential side more than the first end portion 84 and the tube forming portion 86, the second end portion 88 is easily positioned with respect to the members inside the tube portion 82, here with respect to the insulator 70.

[0128] In the present embodiment, a recessed portion 72g is formed in the outer circumferential surface of the insulator 70, and the second end portion 88 is embedded in the recessed portion 72g. Therefore, the outer conductor 80 is easily positioned with respect to the insulator 70.

[0129] In addition, since the deformation absorbing opening 82S is formed in a slit-like opening shape, the effects of deformation caused by riveting are absorbed in the entire length direction of the slit-like deformation absorbing opening 82S. Therefore, the tubular shape of the tube portion 82 is more easily maintained in the desired shape.

[0130] In addition, the effects of deformation caused by riveting are absorbed in the entire length direction of the slit-like deformation absorbing opening 82S extending in a direction intersecting the circumferential direction of the tube portion 82. Therefore, the size or uniformity of the tube portion 82 is not easily affected. In addition, the support position of the elastic pieces 90, 96 by the tube portion 82 is stable, and a desired contact load is easily obtained when connecting the outer conductor 80 to the movable side outer conductor 46.

[0131] In addition, the deformation absorbing opening 82S extends from the base end side opening edge on the side opposite the opening edge in the tube portion 82 to a position beyond the riveting fixed portion 83 in the direction of the center axis X. Therefore, even if the first end portion 84 is deformed by riveting, the deformation does not easily spread to other portions with the deformation absorbing opening 82S as a boundary. In addition, because the deformation absorbing opening 82S extends to a position beyond the riveting fixed portion 83, the deformation of the first end portion 84 caused by riveting does not easily spread in the circumferential direction.

[0132] In addition, the coaxial connector 60 is a structure that also has an inner conductor 62 and an insulator 70, and can electrically connect the outer conductor 80 that houses the insulator 70 to the movable side outer conductor 46 with good connection.

[0133] In addition, the second end portion 88 is fitted into the recessed portion 72g of the insulator 70, so that the outer conductor 80 is positioned with respect to the insulator 70 by the second end portion.

[0134] [Modified Example] In the above embodiment, the structure of the cylindrical portion 82 of the outer conductor 80 can also be applied to the cylindrical portion of another connector conductor. For example, the structure of the first end portion and the second end portion of the cylindrical portion 82 can be applied to the base end cylindrical portion 64 of the inner conductor 62 in the above embodiment so as to coincide and fix the first end portion and the second end portion and form the deformation absorbing opening.

[0135] Note that the structures described in the above embodiment and each modified example can be appropriately combined as long as they do not contradict each other. Explanation of Reference Numerals
