DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described.

[0010] The connectors of the present disclosure are as follows.

[0011] (1) A connector having a connector conductor, the connector conductor including a tubular portion and an elastic piece extending from an opening edge of the tubular portion, the tubular portion having a tubular-shaped tube-forming portion, a first circumferential end portion of the tube-forming portion, and a second circumferential end portion of the tube-forming portion, the elastic piece including an end elastic piece, at least a portion of the end elastic piece extending from the opening edge of the first end portion toward one side in a central axis direction of the tubular portion, the first end portion having a first inner circumferential end portion and a first outer circumferential end portion, the second end portion having a second inner circumferential end portion and a second outer circumferential end portion, the first end portion and the second end portion being fixed in a state in which the first inner circumferential end portion is overlapped on an inner circumferential side of the second outer circumferential end portion and the first outer circumferential end portion is overlapped on an outer circumferential side of the second inner circumferential end portion.

[0012] According to this connector, the first inner peripheral end is overlapped on the inner peripheral side of the second outer peripheral end, and the first outer peripheral end is overlapped on the outer peripheral side of the second inner peripheral end, so that the first end is positioned in both the inner peripheral and outer peripheral directions with respect to the second end. Therefore, the cylindrical portion is easily maintained in a constant shape. Therefore, the elastic pieces including the end elastic pieces are easily held firmly in a constant position suitable for connection with the mating connector, and the desired contact load is easily obtained when connecting the connector conductor to the mating connector.

[0013] (2) In the connector of (1), the tubular portion may further have a first fixing portion that keeps the first inner circumference end portion and the second outer circumference end portion in an overlapping state, and a second fixing portion that keeps the first outer circumference end portion and the second inner circumference end portion in an overlapping state.

[0014] In this case, the first inner peripheral end and the second outer peripheral end are kept overlapping by the first fixing portion, and the first outer peripheral end and the second inner peripheral end are kept overlapping by the second fixing portion. This makes it easier to keep the tubular portion in a constant shape more reliably. Therefore, it is easier to obtain a desired contact load when connecting the connector conductor to the mating connector.

[0015] (3) In the connector of (2), the first fixing portion may be a first crimp fixing portion that crimps and fixes the first inner end portion and the second outer end portion, and the second fixing portion may be a second crimp fixing portion that crimps and fixes the first outer end portion and the second inner end portion.

[0016] If the first fixing portion and the second fixing portion are each a crimping fixing portion, the conductor for a connector can be manufactured at low cost compared to a case in which the conductor for a connector is formed by cutting or welding a plate material.

[0017] (4) In the connector of (1) to (3), a slit may be formed between the first inner end and the first outer end and between the second inner end and the second outer end.

[0018] If a slit is formed between the first inner peripheral end and the first outer peripheral end, the first inner peripheral end and the first outer peripheral end can be easily arranged to be overlapped in the circumferential direction of the tube while being shifted to different positions in the radial direction of the tube. If a slit is formed between the second inner peripheral end and the second outer peripheral end, the second inner peripheral end and the second outer peripheral end can be easily arranged to be overlapped in the circumferential direction of the tube while being shifted to different positions in the radial direction of the tube. This makes it easier to set the overlapping portion of the first inner peripheral end and the second outer peripheral end and the overlapping portion of the first outer peripheral end and the second inner peripheral end to positions close to each other in the circumferential direction of the tube, and the first end can be more reliably positioned in both the inner and outer directions relative to the second end.

[0019] (5) In any one of the connectors of (1) to (4), when a region of the first end including the first inner circumference side end and the first outer circumference side end is defined as an overlapping end, the first end may have a base end located closer to the opening edge than the overlapping end, and a base separation slit may be formed between the overlapping end and the base end.

[0020] In this case, since a base separation slit is formed between the overlapping end and the base end, the processing of the overlapping end is unlikely to affect the base end, so that the elastic piece including the end elastic piece is easily held firmly in a fixed position suitable for connection with the mating connector, and the desired contact load is easily obtained.

[0021] (6) A connector according to any one of (1) to (5), wherein the elastic piece further includes at least one additional elastic piece different from the end elastic piece, and the end elastic piece and the at least one additional elastic piece may be arranged at intervals in the circumferential direction of the tubular portion.

[0022] This allows the connector conductor to be satisfactorily electrically connected to the mating conductor.

[0023] (7) A connector according to any one of (1) to (6), further comprising an inner conductor and an insulator in which the inner conductor is housed, the insulator being housed within the tubular portion.

[0024] In this case, in a connector having an inner conductor, an insulator in which the inner conductor is housed, and a connector conductor as an outer conductor housing the insulator, the connector conductor can be satisfactorily electrically connected to the mating conductor.

[0025] (8) In the connector of (7), the first outer peripheral end, the tube forming portion, and the second outer peripheral end are connected to form a tube shape of the same diameter, the first inner peripheral end and the second inner peripheral end each protrude inwardly beyond the tube forming portion, a recess is formed in an outer peripheral surface of the insulator, and the first inner peripheral end and the second inner peripheral end may be fitted into the recess.

[0026] This makes it possible to position the conductor for a connector with respect to the insulator by utilizing the first inner peripheral end portion and the second inner peripheral end portion.

[0027] (9) In a connector according to (7) or (8), the recess may have a position control surface that receives displacement of the first inner peripheral end portion and the second inner peripheral end portion, whichever is closer to the end elastic piece, toward the end elastic piece.

[0028] In this case, when one of the first and second inner peripheral ends, which is closer to the end elastic piece, tries to move toward the end elastic piece, the end comes into contact with the position restricting surface and the displacement is restricted, thereby more reliably positioning the connector conductor relative to the insulator.

[0029] (10) In any one of the connectors (7) to (9), the bottom surface of the recess may be formed in a position to receive displacement of the first inner circumference side end portion or the second inner circumference side end portion toward the inner circumference side.

[0030] With this, the inward displacement of the first inner circumferential end portion and the second inner circumferential end portion is received by the bottom surface of the recess, so that the cylindrical portion is easily maintained in a constant cylindrical shape.

[0031] (11) A connector according to any one of (7) to (10), wherein a first step portion is located between the tube forming portion and the first inner circumferential end portion, a second step portion is located between the tube forming portion and the second inner circumferential end portion, and the recess may have a first side surface facing the first step portion in the circumferential direction of the tube portion, and a second side surface facing the second step portion in the circumferential direction of the tube portion.

[0032] In this case, when the tube portion tries to open, the first step portion comes into contact with the first side surface and the second step portion comes into contact with the second side surface, thereby preventing the tube portion from expanding.

[0033] (12) In any one of the connectors (7) to (11), the insulator may have a receiving surface at a position closer to the end elastic piece than the recess to receive displacement of the connector conductor toward the inner circumference.

[0034] With this, the first inner peripheral end portion and the second inner peripheral end portion can be positioned by the recess, while the receiving surface can suppress the displacement of the connector conductor toward the inner peripheral side.

[0035] [Details of the embodiment of the present disclosure] Specific examples of the connector of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0036] [Embodiment] A connector according to an embodiment will be described below. In this embodiment, an example in which the connector is a coaxial connector will be described. Note that a coaxial connector is a connector in which an outer conductor and an inner conductor therein are positioned coaxially. It is not essential that the connector is a coaxial connector, and for example, multiple inner conductors may be positioned within the outer conductor.

[0037] <Overall configuration of the equipment> A description will be given of an example of a device 10 equipped with a coaxial connector 60. Fig. 1 is a perspective view showing a device 10 equipped with a coaxial connector 60. Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1.

[0038] The device 10 is, for example, a camera device. The camera device is, for example, a device mounted on a vehicle. The device 10 does not have to be a camera device.

[0039] The device 10 includes a case 12 and an electric component 20. The electric component 20 is accommodated in the case 12. A coaxial connector 60 is fixed to the electric component 20.

[0040] The case 12 includes a first case 13 and a second case 14. The first case 13 and the second case 14 are formed of, for example, resin. The first case 13 and the second case 14 are combined to form the rectangular box-shaped case 12 that houses the electric components 20. If the device 10 is a camera device, it is assumed that the first case 13 has a lens or window for capturing images, and the second case 14 has a coaxial connector 30 for external connection.

[0041] The coaxial connector for external connection 30 is a coaxial connector for connecting the electrical component 20 to an external electrical component. For example, the coaxial connector for external connection 30 is a coaxial connector to which a cable connected to the external electrical component is connected. The cable to which the coaxial connector for external connection 30 is connected is, for example, a coaxial cable.

[0042] More specifically, a holding tube portion 16 is provided to protrude from the bottom 15 of the case 12. The holding tube portion 16 is a cylinder and protrudes outward from the center of the bottom portion 15. The inner opening of the holding tube portion 16 opens into the second case 14, and the outer opening of the holding tube portion 16 opens to the outside of the second case 14. A holding partition portion 17 is formed in the middle portion of the holding tube portion 16 in the direction along the central axis X (axial direction). In this embodiment, the holding partition portion 17 is formed in the middle portion of the holding tube portion 16 in the direction along the central axis X, near the inner opening. The holding partition portion 17 divides the space of the holding tube portion 16 into the space on the inner opening side and the space on the outer opening side. A holding hole 17h is formed in the holding partition portion 17, and the coaxial connector 30 for external connection is inserted and held in the holding hole 17h.

[0043] In this embodiment, a locking protrusion 18a for holding a cable connector attached to an end of a cable is formed on the outer periphery of the holding tube portion 16. It is not essential that the locking protrusion 18a is formed.

[0044] The coaxial connector 30 for external connection comprises an inner conductor 32 for external connection, an insulator 34 for external connection, and an outer conductor 36 for external connection.

[0045] The external connection inner conductor 32 is formed in a long and thin rod shape and is made of a conductive material such as metal. The external connection insulator 34 is made of an insulator such as resin and surrounds the periphery of the external connection inner conductor 32. In this embodiment, the external connection insulator 34 is a dielectric. The external connection outer conductor 36 is made of a conductive material such as metal. The external connection outer conductor 36 is formed in a tubular shape that surrounds the periphery of the external connection insulator 34.

[0046] The electric component 20 is, for example, a mounting board on which electronic components are mounted. When the device 10 is a camera device, the electric component 20 is assumed to be a circuit board 21 and an image sensor 22 mounted on the circuit board 21. The image sensor 22 faces an image capturing lens or window in the first case 13, and captures an image of the outside scenery by rotating the lens or window. Hereinafter, the first case 13 side to which the image sensor 22 faces may be referred to as the front side, and the opposite second case 14 side may be referred to as the rear side.

[0047] In this embodiment, the coaxial connector 60 is located on the surface of the circuit board 21 opposite to the imaging element 22. The coaxial connector 60 is fixed to the circuit board 21 and protrudes from the circuit board 21 toward the coaxial connector 30 for external connection. The coaxial connector 60 is a board-side coaxial connector. The coaxial connector 60 includes, for example, an inner conductor 62, an insulator 70, and an outer conductor 80. A movable-side inner conductor 42, which will be described later, is connected to the inner conductor 62. The insulator 70 surrounds the inner conductor 62. The outer conductor 80 surrounds the insulator 70. That is, the inner conductor 62, the insulator 70, and the outer conductor 80 are concentrically arranged in this order from the center toward the outer periphery.

[0048] The coaxial connector 60 and the coaxial connector for external connection 30 are connected via the relay connector 40. The relay connector 40 includes, for example, a movable inner conductor 42, a movable insulator 44, and a movable outer conductor 46. The movable inner conductor 42 is surrounded by the movable insulator 44. In this embodiment, the movable insulator 44 is a dielectric material. The movable outer conductor 46 surrounds the movable insulator 44. The movable inner conductor 42 is an example of a mating inner conductor connected to the inner conductor 62, the movable outer conductor 46 is an example of a mating outer conductor connected to the outer conductor 80, and the relay connector 40 is an example of a mating coaxial connector connected to the coaxial connector 60, and is also an example of a mating connector.

[0049] The relay connector 40 is connected to the coaxial connector 60 with the movable-side inner conductor 42 inserted and connected to the inner conductor 62 and the outer conductor 80 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 coaxial connector for external connection 30. The external connection inner conductor 32 is inserted and connected to the movable-side inner conductor 42 and the movable-side outer conductor 46 is inserted and connected to the external connection outer conductor 36, thereby connecting the relay connector 40 to the coaxial connector for external connection 30. In this way, the relay connector 40 relays and connects the coaxial connector 60 and the coaxial connector for external connection 30.

[0050] As a result, when an external cable is connected to the coaxial connector 30 for external connection, an external electrical component to which the cable is connected is electrically connected to the electrical component 20 inside the case 12 .

[0051] In the connected state of the relay connector 40 and the coaxial connector 60, the movable-side inner conductor 42 is inserted and connected in a tilted state relative to the inner conductor 62. Also, the outer conductor 80 is inserted and connected in a tilted state relative to the movable-side outer conductor 46. That is, the relay connector 40 can be connected in a tilted state relative to the coaxial connector 60 (see arrow P1 in FIG. 2). As a result, even if the coaxial connector 60 and the external-connection coaxial connector 30 are misaligned from their coaxially opposing positions during the assembly work of the device 10 or in the completed state (see arrow P2 in FIG. 2), the misalignment is absorbed by the inclination of the relay connector 40 relative to the coaxial connector 60.

[0052] <About coaxial connectors> The coaxial connector 60 will be described in detail. Fig. 3 is a perspective view showing the coaxial connector 60. Fig. 4 is an exploded perspective view showing the coaxial connector 60. Fig. 5 is a bottom view showing the coaxial connector 60. Fig. 6 is a cross-sectional view taken along line VI-VI in Fig. 3. Fig. 7 is a cross-sectional view taken along line VII-VII in Fig. 5.

[0053] As described above, coaxial connector 60 includes, for example, inner conductor 62, insulator 70, and outer conductor 80.

[0054] The inner conductor 62 is an elongated conductive member (see FIGS. 2 and 4). In this embodiment, the inner conductor 62 is formed by pressing a metal plate. More specifically, the inner conductor 62 includes a base end tube portion 64 and a plurality of elastic pieces 66.

[0055] The base end tubular portion 64 is formed in a tubular shape, more specifically, in a cylindrical shape. The base end tubular portion 64 is accommodated in the base end side of the insulator 70. Note that, in the coaxial connector 60, the tip is the end on the side to which the movable-side inner conductor 42 is connected, and the base end is the end opposite to the tip, in this case, the end on the side facing the circuit board 21.

[0056] An extension piece 64a extends from the base end edge of the base end tubular portion 64 toward the inside of the base end tubular portion 64. The extension piece 64a is soldered to the circuit of the circuit board 21, for example.

[0057] The base end tube portion 64 may have a positioning protrusion 64P that partially protrudes outward in the circumferential direction. The positioning protrusion 64P may be fitted into a recess in the insulator 70, thereby positioning the inner conductor 62 with respect to the insulator 70.

[0058] A locking protrusion 64b is provided on the base end tubular portion 64. The locking protrusion 64b partially protrudes from the outer periphery of the base end tubular portion 64. The locking protrusion 64b is formed in a shape such that the protruding dimension gradually increases from the tip of the base end tubular portion 64 toward the base end. When the base end tubular portion 64 is inserted into the insulator 70, the locking protrusion 64b gets caught on the inner periphery of the insulator 70, and the inner conductor 62 is held in a state where it is prevented from slipping out of the insulator 70.

[0059] The multiple elastic pieces 66 protrude further toward the distal end from the distal opening of the base end tubular portion 64. Preferably, the multiple elastic pieces 66 are positioned at equal intervals around the central axis X of the tubular portion 72. In this embodiment, the two elastic pieces 66 face each other around the central axis X of the base end tubular portion 64.

[0060] The movable-side inner conductor 42 of the relay connector 40 is inserted from the tip side of the two elastic pieces 66 toward between the two elastic pieces 66. The movable-side inner conductor 42 is sandwiched between the two elastic pieces 66, whereby the movable-side inner conductor 42 is connected to the inner conductor 62.

[0061] The insulator 70 is made of resin or the like. A dielectric can be understood as a type of insulator, and the insulator 70 is also a dielectric. The insulator 70 is, for example, a molded resin part.

[0062] The insulator 70 includes a cylindrical portion 72 and a tip guide portion 76 .

[0063] The tubular portion 72 is formed in a tubular shape capable of accommodating the inner conductor 62. In this embodiment, the tubular portion 72 is formed in a cylindrical shape, and a columnar space is formed therein. The inner conductor is accommodated in the columnar space.

[0064] The outer peripheral surface of the cylindrical portion 72 is formed into a circumferential surface shape centered on the central axis X. The outer conductor 80 is disposed on the outer peripheral side of the cylindrical portion 72. A positioning recess 72g is formed in a part of the circumferential direction of the outer peripheral portion of the cylindrical portion 72. The recess 72g has a pair of first side surfaces 72g1a and second side surfaces 72g1b that face each other in the circumferential direction of the cylindrical portion 72, and a position restriction surface 72g2 that faces the base end side of the cylindrical portion 72 (see FIG. 4). A second end portion 88, which will be described later, fits into the recess 72g. In this state, the position of the second end portion 88 is restricted by the pair of side surfaces 72g1a and 72g1b and the position restriction surface 72g2. As a result, the outer conductor 80 fitted on the outside of the insulator 70 is restricted from rotating significantly around the central axis X with respect to the insulator 70 and from moving toward the tip side.

[0065] A plurality of (four in this embodiment) elongated protrusions 72a are formed on the outer circumferential surface of the cylindrical portion 72. Each of the protrusions 72a extends parallel to the central axis X. The plurality of protrusions 72a are preferably positioned at equal intervals around the central axis X on the outer circumferential surface of the cylindrical portion 72. The protrusions 72a contact the inner circumferential surface of the cylindrical portion 82 at positions distributed in the circumferential direction.

[0066] The tip guide portion 76 is located on the tip 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.

[0067] The inner peripheral surface of the insertion hole 77 is formed in a tapered shape that gradually reduces in diameter toward the inside of the cylindrical portion 72. The tip end of the movable-side inner conductor 42 is guided by the tapered inner peripheral surface of the insertion hole 77 toward between the multiple elastic pieces 66.

[0068] In addition, the outer periphery of the tip guide portion 76 protrudes further outward than the tubular portion 72. An outer periphery guide surface 78 that gradually expands in diameter toward the base end side is formed on the outer periphery of the tip guide portion 76. The outer periphery guide surface 78 serves to guide the tubular portion of the movable-side outer conductor 46 to the outside of the outer conductor 80.

[0069] The annular back surface of the tip guide portion 76 facing the base end side extends perpendicular to the central axis X of the tubular portion 72. Elastic pieces 90, 96, which will be described later, can elastically deform in the radial direction of the tubular portion 72 on the base end side of the annular back surface.

[0070] The outer conductor 80 is made of a conductive material such as metal, and surrounds the insulator 70. The outer conductor 80 is formed, for example, by pressing a metal plate.

[0071] The outer conductor 80 includes a tubular portion 82 and elastic pieces 90 and 96. In this embodiment, the outer conductor 80 includes an end elastic piece 90 and an additional elastic piece 96 as the elastic pieces.

[0072] The tubular portion 82 is formed in a tubular shape in which the tubular portion 72 can be disposed. An end elastic piece 90 and at least one additional elastic piece 96 extend from the tip-side opening edge of the tubular portion 82. The end elastic piece 90 and the at least one additional elastic piece 96 are arranged at intervals in the circumferential direction of the tubular portion 82. In this embodiment, there is one end elastic piece 90 and seven additional elastic pieces 96. These end elastic piece 90 and the at least one additional elastic piece 96 are arranged at equal intervals in the circumferential direction of the tubular portion 82.

[0073] With the base end of the insulator 70 housed within the tubular portion 82, these end elastic pieces 90 and at least one additional elastic piece 96 surround the tubular portion 72 between the tip guide portion 76 and the tubular portion 82.

[0074] The movable-side outer conductor 46 of the relay connector 40 is guided by the outer circumferential guide surface 78 of the tip guide portion 76 to the outer circumferential side of the end elastic piece 90 and the additional elastic piece 96. As a result, the end elastic piece 90 and the additional elastic piece 96 come into contact with the movable-side outer conductor 46 from the inner circumferential side, and the outer conductor 80 and the movable-side outer conductor 46 are connected.

[0075] <About the outer conductor> The outer conductor 80, which is an example of a conductor for a connector, will be described in more detail. Fig. 8 is a perspective view showing the outer conductor 80. As shown in Figs. 2 to 8, the outer conductor 80 includes a tubular portion 82 and elastic pieces 90, 96 extending from an opening edge on the tip side of the tubular portion 82. In this embodiment, the elastic piece 90 includes an end elastic piece 90 and an additional elastic piece 96.

[0076] The cylindrical portion 82 is a portion that is fitted onto the insulator 70. That is, the insulator 70 is housed inside the cylindrical portion 82. The cylindrical portion 82 is held at a fixed position relative to the insulator 70, and serves to support the outer conductor 80 at a fixed position relative to the insulator 70. In addition, for example, if the base end opening of the cylindrical portion 82 is soldered to a circuit of the circuit board 21, such as a ground circuit, it can serve to ground the movable outer conductor 46 to the ground circuit.

[0077] The tube portion 82 includes a first end 84 , a tube forming portion 86 , and a second end 88 .

[0078] The tube forming portion 86 has a tube shape, in this case a partial tube shape. The first end portion 84 is continuous with one circumferential end side of the tube forming portion 86. The tube forming portion 86 and the first end portion 84 form a tube shape together. More specifically, the first end portion 84 and the tube forming portion 86 form one circumference of a tube shape. The first end portion 84 is an end portion on one circumferential side of the tube forming portion 86.

[0079] The second end 88 is continuous with the tube forming portion 86 on the opposite side to the first end 84. The second end 88 is the other circumferential end of the tube forming portion 86. The tube forming portion 86 is located between the first end 84 and the second end 88.

[0080] At least a portion of the first end 84 overlaps with the second end 88. In other words, the first end 84, the tube-forming portion 86, and the second end 88 are formed into a shape that exceeds one revolution of a cylinder, and both ends of the tube portion 82 overlap by the amount that exceeds one revolution.

[0081] The first end 84 has a first inner peripheral end 84a and a first outer peripheral end 84b. The second end 88 has a second inner peripheral end 88a and a second outer peripheral end 88b. The first end 84 and the second end 88 are fixed in a state in which the first inner peripheral end 84a overlaps the inner peripheral side of the second outer peripheral end 88b and the second inner peripheral end 88a overlaps the inner peripheral side of the first outer peripheral end 84b.

[0082] More specifically, a slit 84S is formed along the circumferential direction of the tube portion 82 from the circumferential tip to the base end of the first end 84. The slit 84S is located between the first inner circumferential end 84a and the first outer circumferential end 84b, and the slit 84S separates the first inner circumferential end 84a from the first outer circumferential end 84b. The slit 84S may be a slit having a gap where a pair of opposing inner surfaces are separated, or may be a slit like a cut where a pair of opposing inner surfaces are in contact. In this embodiment, the first inner circumferential end 84a is located closer to the elastic pieces 90, 96 than the first outer circumferential end 84b.

[0083] Also, a slit 88S is formed along the circumferential direction of the tube portion 82 from the circumferential tip to the base end of the second end portion 88. The slit 88S is located between the second inner circumferential end portion 88a and the second outer circumferential end portion 88b, and the slit 88S divides the second inner circumferential end portion 88a and the second outer circumferential end portion 88b. The slit 84S and the slit 88S extend in the circumferential direction of the tube portion 82 at the same position in the direction of the central axis X. The slit 88S may be a slit having a gap in which a pair of opposing inner surfaces are separated, or may be a slit like a cut in which a pair of opposing inner surfaces are in contact. In this embodiment, the second inner circumferential end portion 88a is located farther from the elastic pieces 90, 96 than the second outer circumferential end portion 88b.

[0084] The first inner periphery end may be located farther from the elastic piece than the first outer periphery end, and the second inner periphery end may be located closer to the elastic piece than the second outer periphery end.

[0085] The first outer periphery end portion 84b, the tube forming portion 86, and the second outer periphery end portion 88b are connected to each other to form a tube shape of the same diameter. That is, the first outer periphery end portion 84b, the tube forming portion 86, and the second outer periphery end portion 88b are formed to have a shape having the same radius of curvature about the central axis X. The first outer periphery end portion 84b, the tube forming portion 86, and the second outer periphery end portion 88b extend beyond one revolution, and the tip portion of the first outer periphery end portion 84b and the tip portion of the second outer periphery end portion 88b are adjacent to each other in the direction along the central axis X.

[0086] The first inner peripheral end 84a and the second inner peripheral end 88a protrude inward from the tube forming portion 86. In this embodiment, a first step portion 84k is located between the tube forming portion 86 and the first inner peripheral end 84a. The first step portion 84k protrudes inward from the tube forming portion 86, and the first step portion 84k forms a surface that faces the tube forming portion 86 from the first inner peripheral end 84a. In addition, a second step portion 88k is located between the tube forming portion 86 and the second inner peripheral end 88a. The second step portion 88k protrudes inward from the tube forming portion 86, and the second step portion 88k forms a surface that faces the tube forming portion 86 from the second inner peripheral end 88a.

[0087] The first inner peripheral end 84a and the second inner peripheral end 88a protrude inward relative to the first outer peripheral end 84b, the second outer peripheral end 88b and the tube forming portion 86 by the thickness of the tube portion 82.

[0088] It is preferable that at least a portion of the first inner peripheral side end portion 84a and at least a portion of the second inner peripheral side end portion 88a overlap in the circumferential direction of the tubular portion 82.

[0089] With the tubular portion 72 of the insulator 70 housed within the tubular portion 82, the first inner peripheral end 84a and the second inner peripheral end 88a fit into the positioning recess 72g of the tubular portion 72. In this state, rotation of the outer conductor 80 relative to the insulator 70 is prevented within a range in which the first inner peripheral end 84a and the second inner peripheral end 88a contact one of the pair of side surfaces 72g1a, 72g1b of the recess 72g. Rotation may be restricted by the tip surfaces of the first inner peripheral end 84a and the second inner peripheral end 88a contacting the pair of side surfaces 72g1a, 72g1b, or by the stepped portions 84k and 88k contacting the pair of side surfaces 72g1a, 72g1b.

[0090] Furthermore, when the tube portion 82 tries to open, the first step portion 84k and the second step portion 88k move in directions away from each other and come into contact with the first side surface 72g1a or the second side surface 72g1b. This restricts the opening of the tube portion 82.

[0091] The width of the recess 72g in the outer circumferential direction of the insulator 70 may be the same as or different from the maximum width of the first inner circumferential end portion 84a and the second inner circumferential end portion 88a in the same direction.

[0092] In this embodiment, one of the first inner circumference side end portion 84a and the second inner circumference side end portion 88a, the first inner circumference side end portion 84a, contacts the positional control surface 72g2 of the recess 72g, thereby preventing the tubular portion 72 of the insulator 70 from being over-inserted into the tubular portion 82 of the outer conductor 80.

[0093] It is preferable that a bottom surface 72gb of the recess 72g is formed at a position that receives the inward displacement of the first inner circumferential end portion 84a or the second inner circumferential end portion 88a.

[0094] In this embodiment, the bottom surface 72gb is formed on a surface parallel to the central axis X. With the first inner circumferential end portion 84a and the second inner circumferential end portion 88a disposed within the recess 72g, the tip of the first inner circumferential end portion 84a is located closer to one of the pair of side surfaces 72g1a, 72g1b of the recess 72g (for example, the first side surface 72g1a). In this state, the tip of the first inner circumferential end portion 84a contacts the bottom surface 72gb. This allows the bottom surface 72gb to receive the displacement of the first inner circumferential end portion 84a toward the inner circumferential side.

[0095] The bottom surface 72gb may receive the inward displacement of the first inner circumference side end portion 84a or the second inner circumference side end portion 88a by contacting the inward protruding portion of the crimped fixing portions 83a, 83b, or by contacting the step portions 84k, 88k.

[0096] It is not essential that the bottom surface 72gb and the first inner peripheral end 84a or the second inner peripheral end 88a are in contact with each other. For example, a gap of 1 mm or less may be formed between the first inner peripheral end 84a or the second inner peripheral end 88a and the bottom surface 72gb, and the first inner peripheral end 84a or the second inner peripheral end 88a displaced toward the inner peripheral side may come into contact with the bottom surface 72gb, so that the bottom surface 72gb receives the displacement of the first inner peripheral end 84a or the second inner peripheral end 88a toward the inner peripheral side.

[0097] The recess 72g may have a position restriction surface 72g2 that receives the displacement of the end (here, the first inner end 84a) of the first inner end 84a and the second inner end 88a that is closer to the end elastic piece 90 toward the end elastic piece 90. In this embodiment, the surface of the recess 72g on the end elastic piece 90 side is formed as the position restriction surface 72g2 perpendicular to the central axis X. When the first inner end 84a arranged in the recess 72g is displaced toward the end elastic piece 90, the end surface of the first inner end 84a on the end elastic piece 90 side comes into contact with the position restriction surface 72g2 to restrict the displacement of the first inner end 84a toward the end elastic piece 90 side.

[0098] The insulator 70 may have a receiving surface 70f for receiving the displacement of the outer conductor 80 toward the inner periphery at a position closer to the end elastic piece 90 than the recess 72g.

[0099] In this embodiment, the insulator 70 has a receiving surface 70f on the tip side of the recess 72g. The receiving surface 70f protrudes from the bottom surface 72gb by the thickness of the second end 88. Therefore, the receiving surface 70f can be located on the inner surface side of the base end 84c of the outer conductor 80. In this state, the base end 84c contacts the receiving surface 70f. This allows the receiving surface 70f to receive the displacement of the tube portion 82, here the base end 84c, toward the inner circumference side.

[0100] It is not essential that the receiving surface 70f and the base end 84c are in contact with each other. For example, a gap of 1 mm or less may be formed between the receiving surface 70f and the base end 84c, and the base end 84c displaced toward the inner periphery may come into contact with the receiving surface 70f, so that the receiving surface 70f receives the displacement of the base end 84c toward the inner periphery.

[0101] The receiving surface 70f may receive the displacement of the base end of the end elastic piece 90 toward the inner periphery.

[0102] The first inner peripheral end 84a and the second outer peripheral end 88b are held in an overlapping state by the first fixing portion 83a. The first outer peripheral end 84b and the second inner peripheral end 88a are held in an overlapping state by the second fixing portion 83b.

[0103] In this embodiment, the first fixing portion 83a is a first crimping fixing portion 83a, and the second fixing portion 83b is a second crimping fixing portion 83b.

[0104] The first crimping fixing portion 83a is a portion that crimps and fixes the first inner circumference side end portion 84a and the second outer circumference side end portion 88b, and the second crimping fixing portion 83b is a portion that crimps and fixes the first outer circumference side end portion 84b and the second inner circumference side end portion 88a.

[0105] In this embodiment, a convex portion 84p is formed by plastic deformation on one of the first inner peripheral end portion 84a and the second outer peripheral end portion 88b, and a concave portion 84q is formed by plastic deformation on the other of the first inner peripheral end portion 84a and the second outer peripheral end portion 88b. The convex portion 84p fits into the concave portion 84q, thereby maintaining the first inner peripheral end portion 84a and the second outer peripheral end portion 88b in an overlapping state.

[0106] More specifically, for example, the first inner periphery end 84a and the second outer periphery end 88b overlapped with each other are sandwiched between a press die having a convex portion and a press die having a concave portion and pressed. Then, parts of the first inner periphery end 84a and the second outer periphery end 88b are extrusion-pressed from the convex portion of the press die toward the concave portion of the press die. The first inner periphery end 84a and the second outer periphery end 88b are simultaneously press-molded with a convex portion 84p and a concave portion 84q that fit together (see FIG. 7). For example, the convex portion of the press die is pressed against the outer periphery surface of the first inner periphery end 84a, and the concave portion of the press die is disposed on the inner periphery surface of the second outer periphery end 88b. By the press working, the convex portion 84p that protrudes toward the inner periphery side is formed on the first inner periphery end 84a. Also, the concave portion 84q is formed on the outer periphery surface of the second outer periphery end 88b. The convex portion 84p of the first inner periphery end portion 84a fits into the concave portion 84q of the second outer periphery end portion 88b, so that the first inner periphery end portion 84a and the second outer periphery end portion 88b are kept overlapped with each other.

[0107] Such a joining structure may be, for example, a structure called spot swaging or a structure called draw lock.

[0108] Similarly, the first outer periphery side end portion 84b and the second inner periphery side end portion 88a are kept in an overlapping state by a fitting structure of a recess and a protrusion formed by plastic deformation.

[0109] At least a part of the end elastic piece 90 extends from the opening edge of the first end 84 toward one side in the central axis direction in the circumferential direction of the tubular portion 82. More specifically, the end elastic piece 90 extends from the opening edge on one side of the tubular portion 82 and is a portion that is connected to the movable-side outer conductor 46 as the mating terminal. At least a part of the end elastic piece 90 extends from the first end 84 of the opening edge on one side of the tubular portion 82.

[0110] More specifically, the region including the first inner peripheral end 84a and the first outer peripheral end 84b is regarded as the overlapping end 84w.

[0111] In this embodiment, the first end 84 has a base end 84c located closer to the opening edge than the overlapping end 84w, i.e., closer to the end elastic piece 90. A base separation slit 84SS is formed between the overlapping end 84w and the base end 84c. The base separation slit 84SS is a slit that runs along the circumferential direction of the tube portion 82 from the circumferential tip to the base end of the first end 84. The base separation slit 84SS and the slit 84S extend in parallel with a gap therebetween. The edge of the base end 84c on the end elastic piece 90 side, together with the edge of the tube forming portion 86, forms a circular opening edge of the tube portion 82.

[0112] The end elastic piece 90 extends from an opening edge between the base end piece 84c and the tube forming portion 86 toward one side in the direction of the central axis X. Note that the base end piece 84c may be omitted and the end elastic piece may extend from the first inner peripheral end piece. When the first outer peripheral end piece is disposed closer to the end elastic piece, the end elastic piece may extend from the first outer peripheral end piece.

[0113] The end 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 tubular portion 82 toward one side of the central axis X of the tubular portion 82.

[0114] The inclined portion 92 is a plate-like portion that is directly connected to the base end portion 84c and extends further from the base end portion 84c.

[0115] The inclined portion 92 extends from the edge of the base end 84c on the opening side so as to be inclined (here, inclined toward the outer periphery) with respect to the central axis X. Therefore, a bending portion 91V is formed between the inclined portion 92 of the end elastic piece 90 and the base end 84c. The end elastic piece 90 can elastically deform inward and outward directions of the tubular portion 82 mainly at the tip side portion from the bending portion 91V.

[0116] The bulge 93 extends toward one side of the central axis X while forming a curved surface that is convex outward from the tip of the inclined portion 92. The portion of the bulge 93 that protrudes most toward the outer periphery faces outward in the radial direction of the cylindrical portion 82 and is a contact portion 93a that comes into contact with the movable-side outer conductor 46.

[0117] The tip guide portion 76 is inclined from the tip of the bulging portion 93 toward one side of the central axis X toward the inner periphery.

[0118] When the outer conductor 80 is inserted into the movable-side outer conductor 46, the tip guide portion 76 comes into contact with the opening edge of the movable-side outer conductor 46, thereby guiding the end elastic piece 90 to the inner periphery of the movable-side outer conductor 46. When the outer conductor 80 is inserted into the movable-side outer conductor 46, mainly the inclined portion 92 elastically deforms toward the inner periphery. The elastic force of the inclined portion 92 returning to its original shape causes the contact portion 93a to be elastically pressed against the inner periphery of the movable-side outer conductor 46. In this state, a force toward the inner periphery acts on the first end portion 84 connected to the base end of the end elastic piece 90. For this reason, it is desirable to firmly support the first end portion 84 so that it does not displace toward the inner periphery. As described above, both ends of the tube portion 82 are fixed by the overlapping structure of the first inner peripheral end portion 84a and the second outer peripheral end portion 88b, and the overlapping structure of the first outer peripheral end portion 84b and the second inner peripheral end portion 88a, so that the first end portion 84 is firmly supported so as not to be displaced toward the inner peripheral side.

[0119] As described above, the outer conductor 80 further includes at least one additional elastic piece 96 extending from the opening edge of the tubular portion 82. In this 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.

[0120] The additional elastic piece 96 is formed in the same shape as the end elastic piece 90 except for the portion supported by the tubular portion 82 .

[0121] The multiple elastic pieces 90, 96 are supported so as to be aligned at equal intervals in the circumferential direction of the tubular portion 82. Note that "equal intervals" includes uniformity within an error range (for example, the same within a range of ±5 degrees around the central axis X). When viewed along the central axis X of the tubular portion 82, the multiple elastic pieces 90, 96 are aligned radially with the central axis X of the tubular portion 82 as the center.

[0122] When the outer conductor 80 is inserted into the movable outer conductor 46, the elastic pieces 90, 96 contact the inner periphery of the movable outer conductor 46 at equal intervals along the circumferential direction. Since the elastic pieces 90, 96 have the same shape and are arranged at equal intervals along the circumferential direction of the tubular portion 82, the elastic pieces 90, 96 are pressed against the movable outer conductor 46 under the same conditions. In addition, if the elastic pieces are supported by a tubular member with a slit, the tubular member may elastically deform inward and outward near the slit, so that the force supporting the elastic pieces may be weakened and the elastic force pressing the elastic pieces against the mating conductor may be weakened. In this 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 fixed position, and therefore it is easy to keep the end elastic piece 90 pressed against the movable outer conductor 46 with a desired design contact load.

[0123] <Effects, etc.> In the coaxial connector 60 configured as described above, the first inner peripheral end 84a is overlapped on the inner peripheral side of the second outer peripheral end 88b, and the first outer peripheral end 84b is overlapped on the outer peripheral side of the second inner peripheral end 88a, so that the first end 84 is positioned in both the inner peripheral side and the outer peripheral side with respect to the second end 88. This makes it easy to maintain the cylindrical portion 82 in a constant shape. This makes it easy to hold the elastic pieces 90, 96 including the end elastic piece 90 firmly in a constant position suitable for connection with the mating movable-side outer conductor 46, and makes it easy to obtain a desired contact load.

[0124] In addition, the first inner peripheral end 84a and the second outer peripheral end 88b are kept overlapping by the first fixing portion 83a, and the first outer peripheral end 84b and the second inner peripheral end 88a are kept overlapping by the second fixing portion 83b. This makes it easier to keep the cylindrical portion 82 in a constant shape. This makes it easier to obtain a desired contact load when connecting the coaxial connector 60 to the mating movable outer conductor 46.

[0125] Furthermore, since the first fixing portion 83a is the first crimping fixing portion 83a and the second fixing portion 83b is the second crimping fixing portion 83b, the outer conductor 80 can be manufactured at low cost compared to forming the outer conductor 80 by cutting processing or welding processing of plate material.

[0126] Furthermore, since the slit 84S is formed between the first inner peripheral end 84a and the second outer peripheral end 88b, it is easy to set the first inner peripheral end 84a and the first outer peripheral end 84b to overlapping positions in the circumferential direction of the tubular portion 82 while shifting them to different positions in the radial direction of the tubular portion 82. Furthermore, since the slit 84S is formed between the second inner peripheral end 88a and the second outer peripheral end 88b, it is easy to set the second inner peripheral end 88a and the second outer peripheral end 88b to overlapping positions in the circumferential direction of the tubular portion 82 while shifting them to different positions in the radial direction of the tubular portion 82. The slits 84S, 88S make it easier to set the overlapping point of the first inner peripheral end 84a and the second outer peripheral end 88b and the overlapping point of the first outer peripheral end 84b and the second inner peripheral end 88a in close positions in the circumferential direction of the tubular portion 82, thereby more reliably positioning the first end 84 relative to the second end 88 in both the inner and outer peripheral directions.

[0127] The first end 84 has a base end 84c located closer to the opening edge than the overlapping end 84w, and a base separation slit 84SS is formed between the overlapping end 84w and the base end 84c. Therefore, the processing of the overlapping end 84w is unlikely to affect the base end 84c. Therefore, the elastic pieces 90, 96 including the end elastic piece 90 are easily held in a fixed position suitable for connection with the mating movable-side outer conductor 46, and the desired contact load is easily obtained.

[0128] Moreover, the elastic piece 90 includes an end elastic piece 90 and at least one additional elastic piece 96, and the end elastic piece 90 and the at least one additional elastic piece 96 are arranged at intervals in the circumferential direction of the tubular portion 82. Therefore, the multiple elastic pieces 90, 96 are pressed against the movable-side outer conductor 46 at multiple points distributed in the circumferential direction of the tubular portion 82, and the outer conductor 80 is easily electrically connected to the movable-side outer conductor 46 well.

[0129] Furthermore, in the coaxial connector 60, which is provided with an inner conductor 62 and an insulator 70 that houses the inner conductor 62, and in which the insulator 70 is housed within the tubular portion 82, the outer conductor 80 can be electrically connected well to the mating movable side outer conductor 46.

[0130] Additionally, the first inner peripheral end portion 84a and the second inner peripheral end portion 88a protrude further inward than the tube forming portion 86, and the first inner peripheral end portion 84a and the second inner peripheral end portion 88a fit into the recess 72g of the insulator 70. This allows the outer conductor 80 to be positioned relative to the insulator 70 by utilizing the first inner peripheral end portion 84a and the second inner peripheral end portion 88a.

[0131] Furthermore, when the first inner circumferential end portion 84a and the second inner circumferential end portion 88a attempt to displace toward the end elastic piece 90, the end portion of the first inner circumferential end portion 84a and the second inner circumferential end portion 88a that is closer to the end elastic piece 90, in this case the first inner circumferential end portion 84a, comes into contact with the position restriction surface 72g2 of the recess 72g, and the displacement is restricted. This allows the outer conductor 80 to be more reliably positioned relative to the insulator 70.

[0132] Furthermore, when the first inner peripheral end 84a and the second inner peripheral end 88a attempt to move inward, the first inner peripheral end 84a or the second inner peripheral end 88a comes into contact with the bottom surface 72gb of the recess 72g, thereby restricting the movement. This makes it easier for the cylindrical portion 82 to maintain a constant cylindrical shape.

[0133] Further, a first step portion 84k is located between the tube forming portion 86 and the first inner peripheral end portion 84a, and a second step portion 88k is located between the tube forming portion 86 and the second inner peripheral end portion 88a. Therefore, when the tube portion 82 tries to open, the first step portion 84k contacts the first side surface 72g1a of the recess 72g, and the second step portion 88k contacts the second side surface 72g1b of the recess 72g. This prevents the tube portion 82 from expanding.

[0134] From the viewpoint of suppressing the expansion of the tubular portion 82, it is preferable to position each of the side surfaces 172g1a, 172g1b of the recess 172g corresponding to the recess 72g as close as possible to the first step portion 184k of the first inner periphery end portion 184a corresponding to the first inner periphery end portion 84a and the second step portion 188k of the second inner periphery end portion 188a corresponding to the second inner periphery end portion 88a, as in the case of the coaxial connector 160 according to the modified example shown in Fig. 9. For example, each of the side surfaces 172g1a, 172g1b may be positioned within a distance of 1 mm or less from the facing first step portion 184k or second step portion 188k. In this case, the tip faces of the first inner peripheral end portion 184a and the second inner peripheral end portion 188a may be positioned in the circumferential direction of the tubular portion 82 at a position close to the first step portion 184k or the second step portion 188k, or at a position not protruding further than the first step portion 184k or the second step portion 188k.

[0135] Furthermore, since the insulator 70 has the receiving surface 70f at a position closer to the end elastic piece 90 than the recess 72g, the recess 72g positions the first inner peripheral end 84a and the second outer peripheral end 88b, while the receiving surface 70f suppresses displacement of the outer conductor 80 toward the inner peripheral side, so that the tubular portion 82 is more reliably maintained in a tubular shape.

[0136] [Variations] In the above embodiment, an example has been described in which the first fixing portion 83a and the second fixing portion 83b are crimped fixing portions. The fixing portions may be welded portions by laser welding, resistance welding, or the like, or may be soldered fixing portions. The first fixing portion and the second fixing portion may be omitted, and the ends of the tube portion 82 may be fixed by a configuration in which the first inner peripheral end portion 84a and the second outer peripheral end portion 88b, and the second inner peripheral end portion 88a and the second outer peripheral end portion 88b alternately sandwich the ends from the inner and outer peripheral sides.

[0137] In the above embodiment, the first inner peripheral end portion 84a and the second outer peripheral end portion 88b are overlapped with each other, and the first outer peripheral end portion 84b and the second inner peripheral end portion 88a are overlapped with each other. There may be three or more combinations of overlapping inner peripheral end portions and outer peripheral end portions.

[0138] In the above embodiment, the configuration related to the tubular portion 82 of the outer conductor 80 may be applied to the tubular portion of another connector conductor. For example, the base end tubular portion 64 of the inner conductor 62 in the above embodiment may be applied with a configuration in which multiple sets of inner peripheral end portions and outer peripheral end portions are overlapped with the positions of the inner peripheral side and the outer peripheral side alternately changed.

[0139] The configurations described in the above embodiment and modifications can be combined as appropriate as long as they are not mutually inconsistent. [Explanation of symbols]
