[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 protruding end portion at the tube-forming portion, and a second circumferential protruding end portion at the tube-forming portion, the first protruding end portion and the second protruding end portion protruding along a radial direction of the tube-forming portion, and the first protruding end portion and the second protruding end portion being fixed to each other in a circumferentially overlapping state of the tube-forming portion.

[0012] According to this connector, the first and second protruding ends are fixed to each other while overlapping in the circumferential direction of the tube-forming portion, so that the tube portion is unlikely to open or close and is likely to maintain a constant shape. Therefore, the elastic piece is likely to be firmly held in a constant position suitable for connection with the mating connector, and the desired contact load is likely to be obtained when connecting the connector conductor to the mating connector.

[0013] (2) In the connector of (1), the first protruding end portion and the second protruding end portion may protrude outwardly from the outer periphery of the tube forming portion.

[0014] In this case, the first protruding end portion and the second protruding end portion can be easily fixed on the outer circumferential side of the cylindrical portion.

[0015] (3) The connector of (1) or (2) may further include an end fixing member for keeping the first protruding end and the second protruding end in a fixed state, the end fixing member having a fixing groove formed therein, and the first protruding end and the second protruding end being inserted into the fixing groove in an overlapping state.

[0016] In this case, by inserting the first protruding end portion and the second protruding end portion into the fixing groove while the first protruding end portion and the second protruding end portion are overlapped, the first protruding end portion and the second protruding end portion can be easily kept in a fixed state.

[0017] (4) In the connector of (3), the overlapping body of the first protruding end and the second protruding end has an axial edge extending along the central axial direction of the tubular portion, the fixing groove has an axial inner surface that receives the axial edge, an axial positioning convex portion is formed on one of the axial edge and the axial inner surface, and an axial positioning concave portion is formed on the other of the axial edge and the axial inner surface, and when the first protruding end and the second protruding end are inserted into the fixing groove, the axial positioning convex portion may be engaged with the axial positioning concave portion.

[0018] In this case, since the axial positioning protrusions are engaged with the axial positioning recesses, the end fixing member is prevented from moving axially and falling off the cylindrical portion.

[0019] (5) In a connector according to (3) or (4), the overlapping body of the first protruding end and the second protruding end may have a radial edge extending along the radial direction, the fixing groove may have a radial inner surface that receives the radial edge, a radial positioning convex portion may be formed on one of the radial edge and the radial inner surface, and a radial positioning concave portion may be formed on the other of the radial edge and the radial inner surface, and when the first protruding end and the second protruding end are inserted into the fixing groove, the radial positioning convex portion may be engaged with the radial positioning concave portion.

[0020] In this case, since the radial positioning protrusions are engaged with the radial positioning recesses, the end fixing member is prevented from moving in the radial direction and falling off the tubular portion.

[0021] (6) In the connector of (4), the overlapping body may have a radial edge extending along the radial direction, the fixing groove may have a radial inner surface that receives the radial edge, a radial positioning guide convex portion formed on the radial edge, and a radial positioning guide recess formed on the radial inner surface, and the radial positioning guide convex portion may be slidably inserted into the radial positioning guide recess in the central axial direction to a position beyond the axial positioning convex portion.

[0022] In this case, since the radial positioning guide protrusions are slidably inserted into the radial positioning guide recesses in the central axial direction to a position beyond the axial positioning protrusions, the axial positioning protrusions are easily kept locked in the axial positioning recesses, making it difficult for the end fixing member to fall off from the first protruding end and the second protruding end.

[0023] (7) Any one of the connectors (1) to (6) may be provided, wherein the tubular portion has a first circumferential crimped end at the tube forming portion and a second circumferential crimped end at the tube forming portion, the first crimped end being located adjacent to the first protruding end in the central axial direction of the tubular portion, and the second crimped end being located adjacent to the second protruding end in the central axial direction, and the tubular portion may further have a crimp fixing portion that crimps and fixes the first crimped end and the second crimped end in a state in which the first crimped end and the second crimped end are overlapped in the radial direction.

[0024] In this way, since the first crimped end and the second crimped end are fixed by the crimp fixing portion, the ends of the tube-forming portion are less likely to shift radially, so that the tube portion is more likely to maintain a constant shape, and it is easier to obtain a desired contact load when connecting the connector conductor to the mating connector.

[0025] (8) In the connector of (7), a slit may be formed in the tubular portion between the crimped fixing portion and the elastic piece.

[0026] In this case, even if the first crimped end and the second crimped end are firmly fixed by the crimping fixing portion, the processing for the crimping fixation is unlikely to affect the elastic piece, so the elastic piece can be easily held firmly in a fixed position suitable for connection with the mating connector, and the desired contact load can be easily obtained.

[0027] (9) In the connector of (8), the slit may be located in the central axis direction between the overlapping body of the first protruding end and the second protruding end and the crimped overlapping body of the first crimped end and the second crimped end.

[0028] This makes it possible to prevent the influence of crimping from reaching the elastic piece, and the elastic piece can be firmly held by the overlapping body of the first protruding end portion and the second protruding end portion.

[0029] (10) In any one of the connectors (1) to (9), the connector conductor may include a plurality of the elastic pieces, and the plurality of elastic pieces may be arranged at intervals in the circumferential direction of the tubular portion.

[0030] This allows the connector conductor to be satisfactorily electrically connected to the mating conductor.

[0031] (11) The connector according to any one of (1) to (10), further comprising an inner conductor and an insulator in which the inner conductor is housed, the insulator being housed within the tubular portion.

[0032] In this case, in a connector including 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.

[0033] (12) A connector according to any one of (7) to (10), further comprising an inner conductor and an insulator in which the inner conductor is housed, the insulator is housed within the tubular portion, the tubular portion and the first crimped end are connected to form a tubular shape of the same diameter, the second crimped end is overlapped on the inner side of the first crimped end so as to protrude more inwardly than the tubular portion, a recess is formed on the outer peripheral surface of the insulator, and the second crimped end is fitted into the recess.

[0034] This makes it possible to position the connector conductor relative to the insulator by utilizing the second crimping end portion.

[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 (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> A specific description will be given of the coaxial connector 60. Fig. 3 is a perspective view showing the coaxial connector 60. Fig. 4 is an exploded perspective view showing the coaxial connector 60.

[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 in 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 crimped end portion 89, which will be described later, fits into the recess 72g. In this state, the position of the second crimped end portion 89 is restricted by the pair of side surfaces 72g1a and 72g1b and the position restriction surface 72g2. This restricts the outer conductor 80, which is fitted on the outside of the insulator 70, 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. An elastic piece 90, 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 cylindrical portion 82 and an elastic piece 90. In this embodiment, the outer conductor 80 includes a plurality of elastic pieces 90.

[0072] The tubular portion 82 is formed in a tubular shape in which the tubular portion 72 can be disposed inside. An elastic piece 90 extends from the edge of the tip end opening of the tubular portion 82. The elastic pieces 90 are arranged at intervals in the circumferential direction of the tubular portion 82. In the present embodiment, the outer conductor 80 includes eight elastic pieces 90, and the eight elastic pieces 90 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 cylindrical portion 82 , these elastic pieces 90 surround the periphery of the cylindrical portion 72 between the tip guide portion 76 and the cylindrical portion 82 .

[0074] The movable-side outer conductor 46 of the relay connector 40 is guided to the outer periphery of the multiple elastic pieces 90 by the outer periphery guide surface 78 of the tip guide portion 76. As a result, the multiple elastic pieces 90 come into contact with the movable-side outer conductor 46 from the inner periphery 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. 5 is a partially exploded perspective view showing the coaxial connector 60. Fig. 6 is a perspective view showing the outer conductor 80. Fig. 7 is a partial cross-sectional view taken along line VII-VII in Fig. 3. Fig. 8 is a partial cross-sectional view taken along line VIII-VIII.

[0076] As shown in FIGS. 2 to 8, the outer conductor 80 includes a tubular portion 82 and an elastic piece 90 extending from the edge of an opening on the tip side of the tubular portion 82.

[0077] 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.

[0078] The tube portion 82 includes a tube forming portion 86 , a first protruding end portion 84 , and a second protruding end portion 88 .

[0079] The cylinder forming portion 86 has a cylindrical shape, and in this case, has a cylindrical shape that corresponds to one revolution. The first protruding end portion 84 is continuous with one end side of the cylinder forming portion 86 in the circumferential direction.

[0080] The second protruding end 88 is connected to the opposite side of the tube forming portion 86 from the first protruding end 84. The second protruding end 88 is connected to the other circumferential end of the tube forming portion 86. In the circumferential direction of the tube portion 82, the tube forming portion 86 is located between the first protruding end 84 and the second protruding end 88.

[0081] The first protruding end portion 84 and the second protruding end portion 88 protrude along the radial direction of the tube forming portion 86. In the present embodiment, an example is described in which the first protruding end portion 84 and the second protruding end portion 88 protrude toward the outer periphery of the tube forming portion 86 along the radial direction of the tube forming portion 86. The first protruding end portion 84 and the second protruding end portion 88 are plate-shaped portions extending along the radial direction of the tube forming portion 86 and the direction of the central axis X.

[0082] The first protruding end 84 and the second protruding end 88 are overlapped in the circumferential direction of the tube forming portion 86. In this embodiment, the first protruding end 84 and the second protruding end 88 are rectangular plate shapes extending to the same size, and are overlapped with each other in overall surface contact with each other.

[0083] The first protruding end 84 and the second protruding end 88 are fixed to each other. In this embodiment, the first protruding end 84 and the second protruding end 88 are fixed to each other by an end fixing member 95. The configuration for fixing the first protruding end 84 and the second protruding end 88 is not particularly limited. The first protruding end 84 and the second protruding end 88 may be fixed to each other by welding or crimping.

[0084] The end fixing member 95 is a member that keeps the first protruding end 84 and the second protruding end 88 in a fixed state, and may be, for example, a resin molded part.

[0085] A fixing groove 96 is formed in the end fixing member 95. The fixing groove 96 is formed in a groove shape with one end closed. The width of the fixing groove 96 is set to be equal to or smaller than the width of the overlapping body 83 of the first protruding end portion 84 and the second protruding end portion 88. Preferably, the width of the fixing groove 96 is set to be large enough to allow the overlapping body 83 to be press-fitted therein.

[0086] More specifically, the end fixing member 95 is formed in the shape of a rectangular parallelepiped with rounded corners. It is attached to the stacked body 83 with one main surface facing the outer surface of the tube portion 82. The fixing groove 96 opens on the main surface facing the tube portion 82 and on the upper side. The lower side of the fixing groove 96 is closed. In other words, the fixing groove 96 is a groove that opens on the tube portion 82 side and on the upper side. It is preferable that the fixing groove 96 is large enough to accommodate the entire stacked body 83.

[0087] The stack 83 may be press-fitted into the fixing groove 96 so that the end fixing member 95 is kept attached to the stack 83 by friction between the stack 83 and the fixing groove 96 .

[0088] The first protruding end 84 and the second protruding end 88 are overlapped in the circumferential direction of the tube forming portion 86, so that the tube portion 82 is unlikely to deform so as to reduce in diameter. Also, because the overlapping body 83 of the first protruding end 84 and the second protruding end 88 is inserted into the fixing groove 96, the first protruding end 84 and the second protruding end 88 are unlikely to move in the direction away from each other, so that the tube portion 82 is unlikely to deform so as to increase in diameter.

[0089] In order to prevent the end fixing member 95 from falling off, the following configuration may be adopted.

[0090] An edge of the stack 83 extending along the direction of the central axis X of the cylindrical portion 82 is defined as an axial edge 83a. In this embodiment, the outer peripheral edges of the first protruding end portion 84 and the second protruding end portion 88 are the axial edges 83a.

[0091] An inner surface of the fixing groove 96 that receives the axial edge 83a is referred to as an axial inner surface 96a. In this embodiment, an inner surface of the fixing groove 96 that is located on the outer circumferential side of the cylindrical portion 82 and faces the axial inner surface 96a is referred to as an axial inner surface 96a.

[0092] An axial positioning protrusion 83ap is formed on one of the axial edge 83a and the axial inner surface 96a, and an axial positioning recess 96ag is formed on the other of the axial edge 83a and the axial inner surface 96a.

[0093] In this embodiment, an axial positioning protrusion 83ap is formed on the axial edge 83a. The axial positioning protrusion 83ap is formed in a shape such that the protruding dimension gradually increases toward the top along the central axis X, and the protruding dimension gradually decreases toward the apex. In this embodiment, the portion above the apex has a larger angle with respect to the central axis X than the portion below the apex. The axial positioning protrusion may be formed only on the outer peripheral edge of one of the first protruding end portion 84 and the second protruding end portion 88.

[0094] Further, an axial positioning recess 96ag into which the axial positioning protrusion 83ap fits is formed on the axial inner surface 96a.

[0095] With the stacked body 83 fitted in the fixing groove 96, the axial positioning protrusion 83ap fits into the axial positioning recess 96ag, thereby restricting movement of the central axis X of the end fixing member 95 relative to the stacked body 83. In particular, downward movement of the end fixing member 95 relative to the stacked body 83 is restricted.

[0096] Conversely, the axial positioning protrusion may be formed on the axial inner surface, and the axial positioning recess may be formed on the axial edge.

[0097] Further, the overlapping body 83 has an edge extending along the radial direction of the tubular portion 82 as a radial edge 83b. In this embodiment, the edges on the lower sides (opposite the elastic piece 90) of the first protruding end portion 84 and the second protruding end portion 88 are the radial edge 83b.

[0098] The inner surface of the fixing groove 96 that receives the radial edge 83b is referred to as the radial inner surface 96b. In this embodiment, the lower inner surface of the fixing groove 96 that is located on the opposite side to the elastic piece 90 and faces the radial edge 83b is the radial inner surface 96b.

[0099] A radial positioning protrusion 96bp is formed on one of the radial edge 83b and the radial inner surface 96b, and a radial positioning recess 83bg is formed on the other of the radial edge 83b and the radial inner surface 96b.

[0100] In this embodiment, a radial positioning protrusion 96bp is formed on the radial inner surface 96b. The radial positioning protrusion 96bp is formed in a semicircular protrusion shape.

[0101] Further, a radial positioning recess 83bg into which the radial positioning protrusion 96bp fits is formed on the radial edge 83b. The radial positioning recess 83bg may be formed only on the lower edge of one of the first protruding end portion 84 and the second protruding end portion 88.

[0102] With the stacked body 83 fitted in the fixing groove 96, the radial positioning protrusions 96bp fit into the radial positioning recesses 83bg, thereby restricting radial movement of the end fixing member 95 relative to the stacked body 83. In particular, movement of the end fixing member 95 relative to the stacked body 83 toward the outer periphery is restricted.

[0103] Conversely, the radial positioning protrusions may be formed on the radial edges, and the radial positioning recesses may be formed on the radial inner surfaces.

[0104] The tube portion 82 has a first crimped end portion 85 on one side in the circumferential direction of the tube forming portion 86, and a second crimped end portion 89 on the other side in the circumferential direction of the tube forming portion 86.

[0105] The first crimped end 85 is located adjacent to the lower side of the first protruding end 84 in the direction of the central axis X of the tube portion 82. The first crimped end 85 is located more inward than the first protruding end 84 in the circumferential direction of the tube forming portion 86.

[0106] The second crimped end 89 is located adjacent to the lower side of the second protruding end 88 in the direction of the central axis X of the cylindrical portion 82. The second crimped end 89 extends outward beyond the second protruding end 88 in the circumferential direction of the cylindrical portion 86, and overlaps with the first crimped end 85 in the radial direction of the cylindrical portion 82.

[0107] In this embodiment, the first crimped end 85 is connected to the tube forming portion 86 to form a cylindrical shape of one revolution of the same diameter. The second crimped end 89 is overlapped on the inner peripheral side of the first crimped end 85 so as to protrude further inward than the tube forming portion 86.

[0108] The first crimped end 85 and the second crimped end 89 are crimped and fixed by a crimp fixing portion 99. The crimp fixing portion 99 keeps the first crimped end 85 and the second crimped end 89 in an overlapping state by plastic deformation of at least one of the first crimped end 85 and the second crimped end 89.

[0109] In this embodiment, a convex portion 99a is formed by plastic deformation on one of the first crimped end 85 and the second crimped end 89, and a concave portion 99b is formed by plastic deformation on the other (see FIG. 8). The convex portion 99a fits into the concave portion 99b, thereby keeping the first crimped end 85 and the second crimped end 89 in an overlapping state.

[0110] More specifically, for example, the overlapped first crimped end 85 and second crimped end 89 are sandwiched and pressed between a press die having a convex portion and a press die having a concave portion. Then, parts of the first crimped end 85 and the second crimped end 89 are extrusion-pressed from the convex portion of the press die toward the concave portion of the press die. The first crimped end 85 and the second crimped end 89 are simultaneously press-molded with a convex portion 99a and a concave portion 99b that fit together. For example, the convex portion of the press die is pressed against the outer peripheral surface of the first crimped end 85, and the concave portion of the press die is disposed on the inner peripheral surface of the second crimped end 89. By the press process, a convex portion 99a that protrudes toward the inner peripheral side is formed in the first crimped end 85. In addition, a concave portion 99b is formed on the outer peripheral surface of the second crimped end 89. The convex portion 99a of the first crimped end 85 fits into the concave portion 99b of the second crimped end 89, so that the first crimped end 85 and the second crimped end 89 are kept in an overlapping state.

[0111] Such a joining structure may be, for example, a structure called spot swaging or a structure called draw lock.

[0112] A slit 82S is formed in the tubular portion 82 between the crimped fixing portion 99 and the elastic piece 90. The slit 82S is located, in the direction of the central axis X, between the overlapping body 83 of the first protruding end portion 84 and the second protruding end portion 88 and the crimped overlapping body 99W of the first crimped end portion 85 and the second crimped end portion.

[0113] More specifically, the first protruding end 84 is connected to a portion of one circumferential end of the tube forming portion 86 that is closer to the elastic piece 90. The first crimped end 85 is located at a portion of one circumferential end of the tube forming portion 86 that is away from the elastic piece 90. The slit 82S is located between the first crimped end 85 and a portion of one circumferential end of the tube forming portion 86 that is closer to the elastic piece 90 to which the first protruding end 84 is connected. The slit 82S extends from one circumferential end of the tube portion 82 along the circumferential direction of the tube portion 82 to reach the base end of the first crimped end 85.

[0114] Therefore, the slit 82S extends so as to cross between the crimped end 85 and the elastic piece 90. Therefore, the elastic piece 90 is less susceptible to the effects of deformation caused by the crimping of the crimped fixing portion 99. In addition, the second protruding end 88 can be easily bent and deformed toward the outer periphery without affecting the first crimped end 85.

[0115] The second crimped end 89 protrudes radially inward beyond the tube forming portion 86 and the first crimped end 85 by an amount equivalent to its thickness.

[0116] With the tubular portion 72 of the insulator 70 housed within the tubular portion 82, the second crimped end 89 fits 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 the range where the second crimped end 89 contacts one of the pair of side surfaces 72g1a, 72g1b of the recess 72g.

[0117] The surface of the second crimping end 89 on the elastic piece 90 side comes into contact with the position restriction surface 72g2 of the recess 72g, thereby preventing the tubular portion 72 of the insulator 70 from being excessively inserted into the tubular portion 82 of the outer conductor 80.

[0118] It is preferable that a bottom surface 72gb of the recess 72g is formed at a position that can receive the displacement of the second crimped end portion 89 toward the inner periphery side.

[0119] In this embodiment, the bottom surface 72gb is formed in a plane parallel to the central axis X. With the second crimped end 89 disposed in the recess 72g, the inner peripheral portion of the second crimped end 89 is in contact with the bottom surface 72gb or faces the bottom surface 72gb with a gap therebetween. This allows the bottom surface 72gb to receive the displacement of the second crimped end 89 toward the inner peripheral side.

[0120] It is not essential that the bottom surface 72gb and the second crimped end 89 are in contact with each other. For example, a gap of 1 mm or less may be formed between the bottom surface 72gb and the second crimped end 89, and the second crimped end 89 displaced toward the inner periphery may come into contact with the bottom surface 72gb, thereby allowing the bottom surface 72gb to receive the displacement of the second crimped end 89 toward the inner periphery.

[0121] The insulator 70 may be in contact with the inner circumferential surface of the tube-forming portion 86 at a position closer to the elastic piece 90 than the recess 72g is, to receive the displacement of the outer conductor 80 toward the inner circumferential side.

[0122] The multiple elastic pieces 90 extend from an opening edge on one side of the tube forming portion 86 toward one side in the central axis direction of the tube portion 82. The multiple elastic pieces 90 extend from the opening edge on one side of the tube portion 82 and are portions that are connected to the movable-side outer conductor 46 as the mating terminal.

[0123] The 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 toward one side of the central axis X of the cylindrical portion 82.

[0124] The inclined portion 92 is a plate-like portion that is directly connected to the tube forming portion 86 and extends further from the tube forming portion 86 .

[0125] The inclined portion 92 extends from the edge of the opening side of the tube forming portion 86 so as to be inclined (here, inclined toward the outer periphery) with respect to the central axis X. Therefore, a bending point 91V is formed between the inclined portion 92 of the elastic piece 90 and the tube forming portion 86. The elastic piece 90 can elastically deform inward and outward directions of the tube portion 82 mainly in the portion on the tip side from the bending point 91V.

[0126] 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.

[0127] 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.

[0128] When the outer conductor 80 is inserted into the movable outer conductor 46, the tip guide portion 76 comes into contact with the opening edge of the movable outer conductor 46, thereby guiding the elastic piece 90 to the inner periphery of the movable outer conductor 46. When the outer conductor 80 is inserted into the movable outer conductor 46, the inclined portion 92 is mainly elastically deformed toward the inner periphery. The elastic force of the inclined portion 92 returning to its original shape elastically presses the contact portion 93a against the inner periphery of the movable outer conductor 46. In this state, a force toward the inner periphery acts on the portion of the tube-forming portion 86 that is connected to the base end of the elastic piece 90. For this reason, it is desirable to firmly support the tube-forming portion 86, particularly the end portion of the tube-forming portion 86, so that it is not displaced toward the inner periphery. As described above, both ends of the tube-forming portion 86 are fixed by the overlapping and fixing structure of the first protruding end portion 84 and the second protruding end portion 88 and the crimping and fixing structure of the first crimping end portion 85 and the second crimping end portion 89. Therefore, the cylindrical portion 82 is firmly supported so as to be less likely to deform from its initial shape.

[0129] As described above, the multiple elastic pieces 90 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 are aligned radially with the central axis X of the tubular portion 82 as the center.

[0130] When the outer conductor 80 is inserted into the movable outer conductor 46, the elastic pieces 90 contact the inner periphery of the movable outer conductor 46 at equal intervals along the circumferential direction. Since the elastic pieces 90 have the same shape and are arranged at equal intervals along the circumferential direction of the tubular portion 82, the elastic pieces 90 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, and 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, the tubular portion 82 is likely to be kept in a constant shape, and therefore the elastic pieces 90 are likely to be kept pressed against the movable outer conductor 46 under the same conditions with the desired design contact load.

[0131] <Effects> In the coaxial connector 60 configured as described above, the first protruding end 84 and the second protruding end 88 are fixed to each other while overlapping in the circumferential direction of the tube-forming portion 86, so that the tube portion 82 is unlikely to open or close and is likely to maintain a constant shape. Therefore, the multiple elastic pieces 90 are likely to be firmly held in a constant position suitable for connection with the mating movable-side inner conductor 42, and the desired contact load is likely to be obtained.

[0132] Furthermore, since the first protruding end portion 84 and the second protruding end portion 88 protrude toward the outer periphery of the tube forming portion 86, the first protruding end portion 84 and the second protruding end portion 88 can be easily fixed.

[0133] In addition, since the first protruding end 84 and the second protruding end 88 are inserted into the fixing groove 96 of the end fixing member 95 in an overlapping state, the first protruding end 84 and the second protruding end 88 are easily maintained in a fixed state. In addition, the first protruding end 84 and the second protruding end 88 are more reliably held so as not to open up.

[0134] Furthermore, when the first protruding end 84 and the second protruding end 88 are inserted into the fixing groove 96, the axial positioning convex portion 83ap engages with the axial positioning concave portion 96ag, thereby preventing the end fixing member 95 from moving along the direction of the central axis X and falling off from the tubular portion 82.

[0135] Furthermore, when the first protruding end 84 and the second protruding end 88 are inserted into the fixing groove 96, the radial positioning convex portion 96bp engages with the radial positioning concave portion 83bg, thereby preventing the end fixing member 95 from moving outward and falling off from the tubular portion 82.

[0136] In addition, since the first crimped end 85 and the second crimped end 89 are crimped and fixed by the crimp fixing portion 99 while overlapping in the radial direction, both ends of the tube forming portion 86 are unlikely to be displaced in the radial direction. Therefore, the tube portion 82 is likely to be kept in a constant shape, and a desired contact load is easily obtained when the elastic piece 90 is connected to the opposing movable-side outer conductor 46.

[0137] In addition, since a slit 82S is formed between the crimping fixing portion 99 and the elastic piece 90, even if the first crimping end 85 and the second crimping end 89 are firmly fixed by the crimping fixing portion 99, the processing for the crimping is unlikely to affect the elastic piece 90. Therefore, the elastic piece 90 is likely to be firmly held in a fixed position suitable for connection with the mating outer conductor 80, and the desired contact load is likely to be obtained.

[0138] The slit 82S is located in the direction of the central axis X between the overlapping body 83 of the first protruding end 84 and the second protruding end 88 and the crimped overlapping body 99W of the first crimped end 85 and the second crimped end 89. Therefore, the influence of the crimping is unlikely to extend to the elastic piece 90 side, and the overlapping body 99W of the first protruding end 84 and the second protruding end 88 can firmly hold the elastic piece 90.

[0139] Furthermore, since the multiple elastic pieces 90 are arranged at intervals in the circumferential direction of the tubular portion 82, the multiple elastic pieces 90 can be satisfactorily electrically connected to the mating movable-side outer conductor 46.

[0140] 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.

[0141] A recess 72g is formed on the outer peripheral surface of the insulator 70, and the second crimped end 89 fits into the recess 72g, so that the outer conductor 80 can be positioned relative to the insulator 70 by utilizing the second crimped end 89.

[0142] [Variations] In the above embodiment, as in the modified example shown in FIG. 9, the radial positioning guide protrusion 196bp corresponding to the radial positioning protrusion 96bp and the radial positioning guide recess 183bg corresponding to the radial positioning recess 83bg may be formed longer in the direction of the central axis X.

[0143] Specifically, the radial positioning guide protrusion 196bp protrudes more toward the elastic piece 90, and the radial positioning guide recess 183bg is formed deeper toward the elastic piece 90. In the direction of the central axis X, the radial positioning guide protrusion 196bp and the radial positioning guide recess 183bg extend beyond the axial positioning protrusion 83ap.

[0144] Then, the overlapping body 83 of the first protruding end portion 84 and the second protruding end portion 88 is inserted into the fixing groove 96 from above the end fixing member 95. At this time, with the radial positioning guide convex portion 196bp fitted into the radial positioning guide concave portion 183bg, the axial positioning convex portion 83ap engages with the axial positioning concave portion 96ag located on the inner surface of the fixing groove 96. Therefore, the engaged state between the axial positioning convex portion 83ap and the axial positioning concave portion 96ag is easily maintained, and the end fixing member 95 is less likely to fall off.

[0145] The axial positioning recess 96ag may be a recess formed by cutting or deforming the inner surface of the fixing groove 96 with the axial positioning protrusion 83ap.

[0146] The first and second protruding ends may protrude radially toward the inner periphery of the tube forming portion, and in this case, the first and second protruding ends protruding toward the inner periphery of the tube forming portion may be fixed to the inner periphery of the tube portion by an end fixing member.

[0147] The configurations described in the above embodiments and modifications can be combined as appropriate as long as they are not mutually inconsistent. [Explanation of symbols]
