[0026] [Explanation of Embodiments of the Present Disclosure]

[0027] First, an embodiment of the present disclosure will be explained.

[0028] The connector of the present disclosure,

[0029] (1) An inner conductor and an outer conductor that surrounds the inner conductor, the outer conductor having a first outer conductor and a second outer conductor that are electrically connected to each other, the first outer conductor being a member formed in a cylindrical shape by casting or cutting, having a receiving portion into which at least a part of the second outer conductor enters, and a first locking portion provided on the inner side of the receiving portion, the second outer conductor being a member in a plate shape, having a second locking portion that is locked to the first locking portion, the second locking portion being able to be elastically deformed.

[0030] ​​​According to the connector, since the first outer conductor is a member formed in a cylindrical shape by casting or cutting, the first outer conductor can be formed in a manner that a gap is less likely to occur. As a result, the shielding performance of the first outer conductor can be improved.

[0031] In this case, when the second outer conductor is also a member formed in a cylindrical shape by casting or cutting, both the first outer conductor and the second outer conductor are less likely to be deformed, and therefore, it is considered that they are connected to each other by press-fitting. However, when the connection by press-fitting is considered, in order to ensure the electrical connection reliability, the dimensional tolerance of the first outer conductor and the second outer conductor becomes small, and it can be difficult to manufacture the outer conductors. In this regard, according to the connector, the second outer conductor is a member formed in a plate shape, and has a second locking portion that can be deformed in flexure. Therefore, by causing the second locking portion to be deformed in flexure and be engaged with the first locking portion of the first outer conductor, the dimensional tolerance of the first outer conductor and the second outer conductor can be made large, the manufacture of the outer conductors can be made easy, and the connection in a state where the electrical connection reliability is high can be achieved. In addition, by providing the second outer conductor in a plate shape, the outer conductors can be manufactured at a low cost.

[0032] Further, since at least a portion of the second outer conductor enters the accommodation portion, the thinness of the connector in the direction in which the second outer conductor protrudes from the first outer conductor can be achieved.

[0033] (2) Preferably, the first outer conductor has a through-hole formed at a position corresponding to the first locking portion, and a portion of the second outer conductor is disposed at a position that blocks the through-hole in a state where the second outer conductor is fitted into the accommodation portion.

[0034] A through-hole, for example, for pulling out a mold that forms the first locking portion, is formed in the first outer conductor at a position corresponding to the first locking portion. In the structure in which the through-hole is formed in the first outer conductor, the shielding performance can be reduced. However, according to this structure, the through-hole can be blocked by a portion of the second outer conductor, and therefore, the reduction in the shielding performance of the outer conductors can be suppressed.

[0035] (3) Preferably, the second outer conductor has a counterpart connecting portion that elastically contacts a counterpart outer conductor.

[0036] According to this structure, the electrical connection reliability of the second outer conductor and the counterpart outer conductor can be improved. In addition, since the second outer conductor is a member formed in a plate shape, the counterpart connecting portion that elastically contacts can be easily formed.

[0037] (4) Preferably, the accommodation portion of the first outer conductor is formed in an open manner at one end side of the first outer conductor, and a cylindrical portion that connects to a shield layer of an electric wire is formed in an open manner at the other end side of the first outer conductor, and the opening direction of the accommodation portion and the opening direction of the cylindrical portion cross each other.

[0038] According to this structure, the first outer conductor can be connected to the counterpart outer conductor in a direction intersecting the extension direction of the electric wire connected to the barrel portion. Also, in such a structure, at least a part of the second locking portion enters the housing portion, so the expansion of the outer conductor in the above-mentioned intersecting direction can be suppressed. As a result, the thinness of the connector can be achieved.

[0065] Structure of the first outer conductor 41

[0066] The first outer conductor 41 is a member formed in a tubular shape by casting or cutting. By "formed in a tubular shape by casting or cutting" is meant a process of forming in a tubular shape by casting or cutting, and does not mean bending a metal plate that has been cut to form it in a tubular shape. Further, casting includes die casting. As shown in Figs. 1 and 2, the first outer conductor 41 surrounds the first inner conductor 21. As shown in Figs. 1 and 2, the first outer conductor 41 is formed in a tubular shape by casting. Figure 5 Figure 3 Figure 5 As shown in Figs. 1 and 2, the first outer conductor 41 has a receiving portion 43, a tubular portion 44, a conductor-side fitting hole 45, a conductor-side fitting groove 46, a first locking portion 47, a through-hole 48, and a sleeve positioning portion 49.

Figure 3 Figure 5 ​​​​As shown, the receiving portion 43 is formed with an opening at one end of the first outer conductor 41. The opening direction of the receiving portion 43 is forward. The cylindrical portion 44 extends in the vertical direction. The cylindrical portion 44 is formed with an opening at the other end of the first outer conductor 41. The opening direction of the cylindrical portion 44 is downward. That is, the opening direction of the receiving portion 43 and the opening direction of the cylindrical portion 44 intersect (orthogonal in this embodiment) the opening direction of the cylindrical portion 44. The inner space of the first outer conductor 41 is formed in a shape that is orthogonal to the space extending rearward from the opening of the receiving portion 43 and the space extending upward from the opening of the cylindrical portion 44.

[0068] like Figure 3 and Figure 5 As shown, a conductor-side fitting hole 45 is formed inside the receiving portion 43. The conductor-side fitting hole 45 penetrates the peripheral wall of the cylindrical portion 44 and communicates with the inner space of the cylindrical portion 44. The conductor-side fitting hole 45 opens in front of the first outer conductor 41. The conductor-side fitting hole 45 is positioned slightly above the center of the first outer conductor 41 in the vertical direction. A conductor-side fitting groove 46 is formed along the front-rear direction in the inner peripheral surface of the conductor-side fitting hole 45. The conductor-side fitting groove 46 opens at both the front and rear.

The front surface of the first locking part 47 slopes backward toward the center of the receiving part 43 when viewed from the front. The rear surface of the first locking part 47 extends along both the vertical and horizontal directions.

[0070] like Figure 3 and Figure 9 As shown, the through hole 48 is formed at a position corresponding to each of the pair of first locking portions 47. In this embodiment, "position corresponding to the first locking portion" means rearward of the first locking portion 47 (that is, inside the inner side of the receiving portion 43, further inward than the first locking portion 47). The through hole 48 connects the outer space and the inner space of the receiving portion 43. The through hole 48 is a demolding hole formed during the manufacturing of the first outer conductor 41.

[0071] like Figure 2 As shown, the sleeve positioning part 49 is shaped to protrude from the outer peripheral surface of the cylindrical part 44. The sleeve positioning part 49 protrudes from the left and right sides of the cylindrical part 44 respectively. Figure 8 As shown, a sleeve 70 is positioned below the sleeve positioning part 49. The sleeve positioning part 49 restricts the upward movement of the sleeve 70.

[0072] (Structure of the first dielectric 61)

[0073] like Figure 5 ,Figure 6 as well as Figure 10 As shown, the first dielectric 61 is disposed between the first inner conductor 21 and the first outer conductor 41. The first dielectric 61 has a cavity 63, a locking hole 64, an entry hole 65, a guide groove 66, and a stabilizer fitting groove 67.

[0074] like Figure 5 As shown, cavity 63 extends in the vertical direction. Cavity 63 opens below the first dielectric 61.

[0075] like Figure 6 As shown, a locking hole 64 is formed on the inner peripheral surface of the cavity 63 (more specifically, the rear side of the inner peripheral surface). The locking portion 24 of the first inner conductor 21 enters the locking hole 64.

[0076] like Figure 6 As shown, an inlet hole 65 is formed on the inner circumferential surface of cavity 63 (more specifically, the front side of the inner circumferential surface). The inlet hole 65 is formed opposite to the locking hole 64 in the front-rear direction. The second inner conductor 22 enters and is disposed in the inlet hole 65. The locking hole 64 and the inlet hole 65 are coaxially disposed opposite each other across cavity 63.

[0077] like Figure 6 As shown, a guide groove 66 is formed on the inner circumferential surface of the cavity 63. The guide groove 66 is formed along the vertical direction and is connected to the locking hole 64.

[0078] like Figure 10 As shown, a stabilizer fitting groove 67 is formed on the inner peripheral surface of the cavity 63. The stabilizer fitting groove 67 is formed along the vertical direction. The stabilizer fitting groove 67 is formed at a position corresponding to the stabilizer 25 of the first inner conductor 21. The stabilizer 25 of the first inner conductor 21 enters the stabilizer fitting groove 67.

[0079] (Structure of the second inner conductor 22)

[0080] The second inner conductor 22 is a plate-shaped component, formed by bending a metal plate. For example... Figure 4 and Figure 6 As shown, the second inner conductor 22 extends in the front-to-back direction. The second inner conductor 22 has a second inner conductor body 34, an inner conductor side-mounted connecting portion 35, a second connecting portion 36, an inner conductor side-mounted protrusion 37, and an anti-detachment protrusion 38.

[0081] like Figure 4 and Figure 6 As shown, the second inner conductor body 34 is formed in a cylindrical shape (more specifically, a cylindrical shape) extending in the front-back direction.

[0082] like Figure 4 and Figure 6As shown, the inner conductor-side mating connection 35 is positioned forward of the second inner conductor body 34. The inner conductor-side mating connection 35 connects to the mating inner conductor 92 of the mating connector 90 (see reference). Figure 5 Electrical connection.

[0083] like Figure 4 and Figure 6 As shown, the second connecting portion 36 is positioned rearward of the second inner conductor body 34. The second connecting portion 36 is configured as a tab. The second connecting portion 36 protrudes rearward of the rear end of the second dielectric 62. The second connecting portion 36 is electrically connected to the first connecting portion 31 of the first inner conductor 21.

[0084] like Figure 6 As shown, the inner conductor side protrusion 37 is provided on the outer peripheral surface of the second inner conductor body 34 and protrudes upward from the outer peripheral surface. When the second inner conductor 22 is inserted into the second dielectric 62, when the inner conductor side protrusion 37 contacts the rear surface of the second dielectric 62, it can restrict the forward movement of the second inner conductor 22 relative to the second dielectric 62.

[0085] like Figure 9 As shown, anti-detachment protrusions 38 are provided on the left and right sides of the second inner conductor body 34, protruding outwards in the left and right directions. The anti-detachment protrusions 38 prevent the second inner conductor 22, which is properly inserted relative to the second dielectric 62, from falling backwards.

[0086] (Structure of the second outer conductor 42)

[0087] The second outer conductor 42 is a plate-shaped component, formed by bending a metal plate. For example... Figure 6 As shown, the second outer conductor 42 surrounds the second inner conductor 22. The second outer conductor 42 is formed into a cylindrical shape (more specifically, a cylindrical shape) extending in the front-to-back direction. The second outer conductor 42 has openings at the front and back. Figure 3 As shown, the second outer conductor 42 has an outer conductor body 50, a second locking part 51, a protrusion 52, a front stop part 53, and a connecting part 54 for the other side.

[0088] like Figure 3 As shown, the outer conductor body 50 is cylindrical (more specifically, circular).

[0089] like Figure 3 and Figure 9As shown, the second locking part 51 protrudes rearward from the outer conductor body 50. The second locking part 51 is cantilevered and supported on the outer conductor body 50. The second locking part 51 is provided on the left and right sides of the outer conductor body 50. The second locking part 51 is plate-shaped and can be bent and deformed towards the center side (i.e., radially inward) of the second outer conductor 42 when viewed from the front. A locking hole 55 is formed in the second locking part 51. The second locking part 51 is locked onto the first locking part 47 of the first outer conductor 41 by the first locking part 47 being inserted into the locking hole 55.

[0090] like Figure 3 As shown, the protrusion 52 protrudes upward from the upper surface of the outer conductor body 50. The protrusion 52 is provided at the rear end of the outer conductor body 50.

[0091] like Figure 3 As shown, the front stop 53 is positioned forward of the outer conductor body 50. The front stop 53 restricts the movement of the second dielectric 62, which is positioned inside the second outer conductor 42, forward.

[0092] like Figure 3 As shown, the counterpart connection portion 54 is supported on the outer conductor body 50. A portion of the outer conductor body 50 is cut out. The counterpart connection portion 54 is disposed in this cut-out portion. The counterpart connection portion 54 is supported by its rear end, thereby cantileveredly supported on the periphery of the cut-out portion of the outer conductor body 50. The counterpart connection portion 54 is flexible and deformable. The counterpart connection portion 54 connects to the counterpart-side outer conductor 93 of the counterpart-side connector 90 (see reference). Figure 5 The connection is electrically connected to the ground via a flexible contact. The counterpart connection portion 54 has a guiding surface 56 that guides the counterpart outer conductor 93 when connected to it. The guiding surface 56 is formed at the front end of the counterpart connection portion 54. The guiding surface 56 is inclined radially outward as it faces rearward. The guiding surface 56 guides the counterpart outer conductor 93 radially outward from the counterpart connection portion 54. The radially outward side of the counterpart connection portion 54 is electrically connected to the counterpart outer conductor 93.

[0093] (Structure of the second dielectric 62)

[0094] like Figure 6 As shown, the second dielectric 62 is disposed between the second inner conductor 22 and the second outer conductor 42. The second dielectric 62 is cylindrical (more specifically, cylindrical).

[0095] (Other structures)

[0096] Figure 5 The sleeve 70 shown is cylindrical (more specifically, cylindrical). The sleeve 70 is, for example, made of metal. Figure 5The first sealing member 71 and the second sealing member 72 shown are cylindrical (more specifically, cylindrical). The first sealing member 71 and the second sealing member 72 are, for example, made of rubber. The first sealing member 71 is fitted onto the outer periphery of the wire 80. The second sealing member 72 is fitted onto the outer periphery of the inner cover 15 of the housing 11. The anti-detachment member 73 is a member that prevents the first sealing member 71, disposed within the housing 11, from falling off. Figure 1 and Figure 5 As shown, the anti-detachment member 73 has an insertion hole 74 and a second anti-detachment locking part 75. An electric wire 80 is inserted into the insertion hole 74. The second anti-detachment locking part 75 locks into the first anti-detachment locking part 18 of the housing 11.

[0097] (Assembly of connector 10)

[0098] Main reference Figure 5 The following explanation is provided. First, the anti-detachment member 73, the first sealing member 71, and the sleeve 70 are sequentially assembled onto the wire 80, starting from the top side. Then, the sheath 84 is removed from the top of the wire 80 to expose the shielding layer 83. Further up the wire 80, the insulator 82 is removed to expose the inner conductor 81. The exposed inner conductor 81 is crimped to the cylindrical portion 26 of the first inner conductor 21.

[0099] The first inner conductor 21 is inserted into the cavity 63 of the first dielectric 61 from below. The first inner conductor 21 is inserted into the cavity 63 with the stabilizer 25 embedded in the stabilizer fitting groove 67 of the first dielectric 61. During insertion into the cavity 63, the locking portion 24 of the first inner conductor 21 engages with the guide groove 66 formed on the inner circumferential surface of the cavity 63 and slides upward along the guide groove 66. While engaged in the guide groove 66, the locking portion 24 is subjected to a reaction force from the bottom surface of the guide groove 66 and becomes flexed. When the first inner conductor 21 is inserted into the correct insertion position, the locking portion 24, through its own elastic restoring force, enters the locking hole 64 connected to the guide groove 66. Thus, the first inner conductor 21 is locked into the first dielectric 61 and is prevented from falling downward from the cavity 63. When the locking part 24 is inserted into the locking hole 64, the opening between the pair of first connecting parts 31 becomes the state facing the entry hole 65 of the first dielectric 61.

[0100] The first dielectric 61 is inserted into the inner side of the first outer conductor 41 from below. When the first dielectric 61 is inserted into the correct insertion position, the inlet hole 65 and the conductor-side fitting hole 45 of the first outer conductor 41 are arranged in a front-back direction. The exposed shielding layer 83 covers the outer peripheral surface of the cylindrical portion 44 of the first outer conductor 41 and is pressed against the sleeve 70. Thus, the first outer conductor 41 is electrically connected to the shielding layer 83 of the wire 80.

[0101] The first outer conductor 41 is inserted into the housing main body 12 of the housing 11 from below. When the first outer conductor 41 is inserted into a regular insertion position, the conductor-side fitting hole 45 of the first outer conductor 41 is arranged in the front-rear direction with the fitting hole 13 of the housing 11, and the conductor-side fitting groove 46 of the first outer conductor 41 is arranged in the front-rear direction with the fitting groove 14 of the housing 11. As shown in FIG. 3, the first locking portion 47 is arranged so as to face the rear of the fitting hole 13. After the first outer conductor 41 is inserted, the second anti-extraction locking portion 75 of the anti-extraction member 73 is locked to the first anti-extraction locking portion 18 of the housing 11. Figure 9

[0102] The second inner conductor 22 is inserted from the rear to the inner side of the second dielectric body 62. The second inner conductor 22 is restricted from moving in the front-rear direction with respect to the second dielectric body 62 when inserted into a regular insertion position by the inner-conductor-side protrusion 37 and the anti-extraction protrusion 38. The second dielectric body 62 is inserted from the rear to the inner side of the second outer conductor 42. The second dielectric body 62 is restricted from moving in the front direction by coming into contact with the front stop portion 53 of the second outer conductor 42. The second outer conductor 42 is fitted to the fitting hole 13 of the housing 11 from the front with the protrusion 52 fitted to the fitting groove 14 of the housing 11. When the fitting of the second outer conductor 42 is further advanced, the second outer conductor 42 is fitted to the conductor-side fitting hole 45 of the first outer conductor 41, and the protrusion 52 of the second outer conductor 42 is fitted to the conductor-side fitting groove 46 of the first outer conductor 41.

[0103] During the fitting of the second outer conductor 42 to the conductor-side fitting hole 45 in the receiving portion 43, the second locking portion 51 is pressed by the first locking portion 47 and is deformed inwardly. When the fitting is further advanced, the first locking portion 47 is inserted into the locking hole 55 of the second locking portion 51, and the second locking portion 51 is restored to the original shape by the elastic restoring force thereof. Thus, the second locking portion 51 is locked to the first locking portion 47.

[0104] When the second locking portion 51 is locked to the first locking portion 47, the second outer conductor 42 is linked to the first outer conductor 41. The first outer conductor 41 is configured not to be extracted from the fitting hole 13 in the housing main body 12. Therefore, even if the second outer conductor 42 linked to the first outer conductor 41 is pulled in a direction to be extracted from the fitting hole 13, the first outer conductor 41 is hooked in the housing main body 12. That is, the second outer conductor 42 is arranged in the fitting hole 13 in a manner not to be extracted in a state in which the second locking portion 51 is locked to the first locking portion 47.

[0105] ​In the course of the second outer conductor 42 being fitted into the conductor-side fitting hole 45 in the housing portion 43, the second connecting portion 36 of the second inner conductor 22 enters the entry hole 65 of the first dielectric body 61 while the pair of first connecting portions 31 of the first inner conductor 21 are spread apart. In the state in which the second inner conductor 22 is normally connected to the first inner conductor 21, the second inner conductor 22 becomes sandwiched by the pair of first connecting portions 31 of the first inner conductor 21, and the tip end of the second connecting portion 36 of the second inner conductor 22 is disposed inside the concave surface 24B. At this time, the tip end of the second connecting portion 36 of the second inner conductor 22 does not contact the concave surface 24B.

[0106] However, a second outer conductor 42B, which will be described later, that is separate from the second outer conductor 42 can be fitted into the housing portion 43 of the first outer conductor 41. That is, the connector 10 is a structure in which one of a plurality of second outer conductors, in the case of the present embodiment, the second outer conductor 42 and the second outer conductor 42B, is selected to be connected to the first outer conductor 41. The second outer conductor 42B has an outer conductor body 50B, a second locking portion 51B, a protrusion 52B, and a counterpart connecting portion 54B.

[0107] The outer conductor body 50B is formed in a cylindrical shape (more specifically, a circular cylindrical shape) that extends in the front-rear direction. The second locking portion 51B is disposed on the rear side of the outer conductor body 50B.

[0108] The second locking portion 51B is provided on both left and right sides of the second outer conductor 42B. The second locking portion 51B is formed with a second lock hole 55B. The second locking portion 51B is formed in the same shape as the second locking portion 51.

[0109] The protrusion 52B is provided to the outer peripheral surface of the outer conductor body 50B. The protrusion 52B protrudes upward from the upper end portion of the outer peripheral surface of the outer conductor body 50B. The protrusion 52B is formed in the same shape as the protrusion 52.

[0110] The counterpart connecting portion 54B is formed in a shape in which the front end thereof is cantilevered to the outer conductor body 50B and protrudes in the front direction. The counterpart connecting portion 54B is provided with a plurality of (six in the present embodiment) at equal intervals in the circumferential direction. The counterpart connecting portion 54B is elastically deformable. The counterpart connecting portion 54B is electrically connected in elastic contact with the counterpart-side outer conductor 93 (see FIG. 6) of the counterpart-side connector 90. The counterpart connecting portion 54B has an induction surface 56B that induces the counterpart-side outer conductor 93 when connected thereto. Figure 5 ) The counterpart connecting portion 54B is formed in a shape in which the front end thereof is cantilevered to the outer conductor body 50B and protrudes in the front direction. The counterpart connecting portion 54B is provided with a plurality of (six in the present embodiment) at equal intervals in the circumferential direction. The counterpart connecting portion 54B is elastically deformable. The counterpart connecting portion 54B is electrically connected in elastic contact with the counterpart-side outer conductor 93 (see FIG. 6) of the counterpart-side connector 90. The counterpart connecting portion 54B has an induction surface 56B that induces the counterpart-side outer conductor 93 when connected thereto.

[0111] The induction surface 56B is formed to the front end portion of the counterpart connecting portion 54B. The induction surface 56B is inclined to the radial inner side as it goes toward the rear direction. The induction surface 56B induces the counterpart-side outer conductor 93 to the radial inner side of the counterpart connecting portion 54B. The radial inner side of the counterpart connecting portion 54B is electrically connected to the counterpart-side outer conductor 93.

[0112] That is, the second locking portion 51 and the second locking portion 51B are formed in the same shape as each other, and are formed in a shape that is locked in the first locking portion 47, respectively. Therefore, when the second outer conductor 42 and the second outer conductor 42B, which are selected, are fitted in the housing portion 43 of the first outer conductor 41, the second locking portion of the fitted second outer conductor is locked in the first locking portion 47 of the first outer conductor 41, and the second outer conductor is linked to the first outer conductor 41. As a result, the second outer conductor is electrically connected to the first outer conductor 41. On the other hand, the counterpart connecting portion 54 and the counterpart connecting portion 54B are formed in different shapes from each other, and are formed in a shape that is connected to the counterpart connecting portion of the different shape. Therefore, it is possible to fit the counterpart connector corresponding to the second outer conductor linked to the first outer conductor 41 to the connector 10.

[0113] (Effect of the connector 10)

[0114] The connector 10 can form the first outer conductor 41 in a manner that a gap is not easily generated because the first outer conductor 41 is a member formed in a cylindrical shape by casting or cutting processing, and as a result, the shielding performance of the first outer conductor 41 can be improved.

[0115] Here, in a case where the second outer conductor 42 is also a member formed in a cylindrical shape by casting or cutting processing, both the first outer conductor 41 and the second outer conductor 42 are not easily deformed, and therefore, it is considered that they are linked by press-fitting. However, in a case where they are linked by press-fitting, when it is necessary to ensure the electrical connection reliability, the dimensional tolerance of the first outer conductor 41 and the second outer conductor 42 becomes small, and it can be difficult to manufacture the outer conductor 40. In this regard, according to the connector 10, the second outer conductor 42 is a member formed in a plate shape, and has the second locking portion 51 that can be deformed by flexure. Therefore, the second locking portion 51 is locked in the first locking portion 47 of the first outer conductor 41 by being deformed by flexure, and as a result, the dimensional tolerance of the first outer conductor 41 and the second outer conductor 42 is made large, the outer conductor 40 is easily manufactured, and the linking in a state where the electrical connection reliability is high can be achieved. In addition, by providing the second outer conductor 42 in a plate shape, the outer conductor 40 can be manufactured at a low cost.

[0116] Further, because a part of the second outer conductor 42 enters the housing portion 43, the thinness of the connector 10 in a direction in which the second outer conductor 42 protrudes from the first outer conductor 41 can be achieved.

[0117] Further, the second locking portion 51 of the second outer conductor 42 is disposed at a position that blocks the through-hole 48 in a state where the second outer conductor 42 is fitted in the housing portion 43. Therefore, it is possible to suppress the decrease in the shielding performance of the outer conductor 40.

[0118] Further, the second outer conductor 42 has a counterpart connecting portion 54 that contacts a counterpart outer conductor of the counterpart connector 90. Therefore, the connector 10 can improve the electrical connection reliability of the second outer conductor 42 and the counterpart outer conductor 93. In addition, because the second outer conductor 42 is a plate-shaped member, the counterpart connecting portion 54 that elastically contacts can be easily formed.

[0119] Further, the connector 10 is a structure that selects any one of a plurality of second outer conductors 42, 42B to be connected to the first outer conductor 41, and the plurality of second outer conductors 42, 42B have counterpart connecting portions 54, 54B that have different shapes from each other. Therefore, a plurality of connectors that use the first outer conductor 41 as a common component and can be fitted to a plurality of counterpart outer conductors can be manufactured.

[0120] Further, the connector 10 is latched to the latching hole 64 by the latching portion 24, and thus the first inner conductor 21 can be prevented from being detached from the first dielectric body 61. Moreover, the latching portion 24 is a double support beam shape in which the upper and lower end portions are supported by the first inner conductor main body 23. Therefore, according to the connector 10, compared to a structure in which the latching portion is a lance-shaped portion, the impedance of the first inner conductor 21 can be prevented from being reduced.

[0121] Further, the latching portion 24 is bent. Therefore, the connector 10 can reduce the insertion force when the first inner conductor 21 is inserted into the inside of the first dielectric body 61.

[0122] Further, the latching hole 64 and the entry hole 65 of the first dielectric body 61 are arranged coaxially with each other with the cavity 63 interposed therebetween. Therefore, when the connector 10 is manufactured, the same mold that forms the latching hole 64 and the entry hole 65 can be used to perform demolding at the same time.

[0123] Further, in a state in which the second inner conductor 22 is normally connected to the first inner conductor 21, the tip end of the second connecting portion 36 is arranged inside the concave surface 24B. Therefore, in the case where the first inner conductor 21 is in the half-inserted state, the tip end of the second connecting portion 36 comes into contact with the first inner conductor 21. Therefore, it can be easily determined whether the first inner conductor 21 is in the half-inserted state. In particular, in the present embodiment, in a state in which the tip end of the second inner conductor 22 comes into contact with the first inner conductor 21, the second locking portion 51 of the second outer conductor 42 is not latched to the first locking portion 47 of the first outer conductor 41. Therefore, according to the non-latching, it can be more simply determined that the first inner conductor 21 is in the half-inserted state.

[0124] Further, a guide groove 66 is formed in the inner peripheral surface of the cavity 63, and the guide groove 66 is formed along the up-and-down direction and is continuous with the latching hole 64. Therefore, the connector 10 can guide the latching portion 24 of the first inner conductor 21 that is inserted into the cavity 63 to the latching hole 64 using the guide groove 66.

[0125] Further, the first locking portion 47 of the connector 10 is arranged so as to face the inner side of the fitting direction of the second outer conductor 42 in the fitting hole 13 in a state where the first outer conductor 41 is arranged in the normal insertion position. Also, the second locking portion 51 is latched to this first locking portion 47. In a state where the second locking portion 51 is latched to the first locking portion 47, the second outer conductor 42 is arranged in the fitting hole 13 in a manner that is prevented from being removed. Conversely, in the case where the first outer conductor 41 is in the half-inserted state, the positions of the second locking portion 51 and the first locking portion 47 are misaligned with each other, and thus the second locking portion 51 is not latched to the first locking portion 47, and the second outer conductor is removed from the fitting hole. Thus, according to the connector 10, it is possible to suppress the latching of the first outer conductor 41 and the second outer conductor 42 in the case of the half-inserted state.

[0126] Further, the housing 11 has a fitting groove 14 formed in the inner circumferential surface of the fitting hole 13 along the fitting direction of the second outer conductor 42, and the second outer conductor 42 has a protruding portion 52 that is fitted into the fitting groove 14 in the fitting process with respect to the first outer conductor 41. Thus, the connector 10 can perform positioning of the second outer conductor 42 with respect to the circumferential direction of the housing 11.

[0127] Further, the housing 11 is in an L shape, and the first outer conductor 41 and the second outer conductor 42 do not have a housing locking portion that is latched to the housing 11, and thus the first outer conductor 41 and the second outer conductor 42 are easily removed from the housing 11 in a state where they are not connected to each other. Thus, according to this structure, it is easy to confirm whether the first outer conductor 41 and the second outer conductor 42 are properly connected.

[0128] Further, the connector 10 is in a state where the second locking portion 51 is latched to the first locking portion 47, and the protruding portion 52 of the second outer conductor 42 is fitted into the conductor-side fitting groove 46 of the first outer conductor 41, and thus it is possible to perform positioning of the second outer conductor 42 with respect to the circumferential direction of the first outer conductor 41.

[0129] Further, the shield layer 83 of the electric wire 80 is electrically connected to the first outer conductor 41. The first outer conductor 41 is electrically connected to the second outer conductor 42, and the counterpart outer conductor 93 of the counterpart connector 90 is electrically connected to the second outer conductor 42. Also, the second outer conductor 42 extends in a direction that intersects (more specifically, is orthogonal to) the extending direction of the first outer conductor 41. Thus, the connector 10 can change the path in a direction that intersects the extending direction of the electric wire 80.
