[0025] [Description of embodiments of this disclosure]

[0026] First, the implementation methods of this disclosure are listed and explained.

[0027] The connector disclosed herein,

[0028] (1) A connector having a housing, an inner conductor, and an outer conductor, the outer conductor surrounding the inner conductor and disposed in the housing, the outer conductor having a first outer conductor electrically connected to a shield layer of an electric wire, and a second outer conductor electrically connected to the first outer conductor and electrically connected to an opposite-side outer conductor of an opposite-side connector, the housing having an insertion hole into which the second outer conductor is fitted, the first outer conductor having a first locking portion disposed so as to face an inner side of a fitting direction of the second outer conductor in the insertion hole in a state where the first outer conductor is disposed in a normal insertion position, the second outer conductor having a second locking portion latched to the first locking portion in the state where the first outer conductor is disposed in the normal insertion position, the second outer conductor being disposed in the insertion hole in a state where the second locking portion is latched to the first locking portion in a manner that the second outer conductor is prevented from being removed.

[0029] The first locking portion of the connector is disposed so as to face an inner side of a fitting direction of the second outer conductor in the insertion hole in a state where the first outer conductor is disposed in a normal insertion position. Also, the second locking portion is latched to the first locking portion. In a state where the second locking portion is latched to the first locking portion, the second outer conductor is disposed in the insertion hole in a manner that the second outer conductor is prevented from being removed. That is, in a case where the first outer conductor is in a half-inserted state, the mutual positions of the second locking portion and the first locking portion are misaligned, and thus the second locking portion is not latched to the first locking portion, and the second outer conductor is removed from the insertion hole. Therefore, according to the connector, it is possible to suppress the mutual latching of the first outer conductor and the second outer conductor in the half-inserted state.

[0030] (2) Preferably, the housing has a fitting groove formed in an inner peripheral surface of the insertion hole along the fitting direction of the second outer conductor, and the second outer conductor has a protrusion fitted to the fitting groove in a fitting process with respect to the first outer conductor.

[0031] According to this structure, it is possible to perform positioning of the second outer conductor with respect to the circumferential direction of the housing.

[0032] (3) Preferably, the first outer conductor has a conductor-side insertion hole and a conductor-side fitting groove formed in an inner peripheral surface of the conductor-side insertion hole along the fitting direction of the second outer conductor, and the protrusion of the second outer conductor is fitted to the conductor-side fitting groove in a state where the second locking portion is latched to the first locking portion.

[0033] According to this structure, in a state where the second locking portion is latched to the first locking portion, the protrusion of the second outer conductor is fitted to the conductor-side fitting groove of the first outer conductor, and thus it is possible to perform positioning of the second outer conductor with respect to the circumferential direction of the first outer conductor.

[0034] (4) Preferably, the housing is L-shaped, and the first outer conductor and the second outer conductor do not have a housing locking part that is locked to the housing.

[0035] The housing is L-shaped, and neither the first nor the second outer conductor has a locking part that engages with the housing. Therefore, the first and second outer conductors can easily detach from the housing when they are not connected to each other. Thus, with this structure, it is easy to confirm whether the first and second outer conductors are correctly connected.

[0036] (5) Preferably, the first outer conductor is formed into a cylindrical component by casting or machining, the second outer conductor is a plate-shaped component, and the second locking part is flexibly deformable.

[0037] According to this structure, since the first outer conductor is formed into a cylindrical component by casting or machining, it can be formed in a way that minimizes gaps. As a result, the shielding performance of the first outer conductor can be improved. Furthermore, since the second locking part can be flexibly deformed, by flexing and deforming the second locking part and locking it against the first locking part of the first outer conductor, a connection with high electrical connection reliability can be achieved.

[0042] (Summary of Connector 10)

[0043] like Figure 1 As shown, connector 10 is L-shaped. Figure 5As shown, a counterpart connector 90 is fitted into one end of connector 10, and a wire 80 is electrically connected to the other end of connector 10. The wire 80 is a shielded wire, configured as a coaxial cable in this embodiment. The wire 80 has an inner conductor 81, an insulator 82, a shielding layer 83, and a sheath 84.

[0045] (Structure of shell 11)

[0046] The housing 11 is insulating and made of synthetic resin. For example... Figure 1 As shown, the casing 11 is L-shaped. Figure 1 and Figure 5 As shown, the housing 11 has a housing body 12, a fitting hole 13, a fitting groove 14, an inner cover 15, an outer cover 16, a locking arm 17, and a first anti-disengagement locking part 18.

[0047] like Figure 5 As shown, the housing body 12 is formed in a cylindrical shape (more specifically, a square tube shape) extending in the vertical direction. The lower end of the housing body 12 is open at the bottom, and the upper end is closed.

[0048] like Figure 5 As shown, the fitting hole 13 is formed penetrating outward from the inner circumference of the housing body 12. That is, the fitting hole 13 penetrates the wall portion (front wall in this embodiment) of the housing body 12 in the front-rear direction. The fitting hole 13 is open at the front of the housing 11. The fitting hole 13 is located above the center of the housing body 12 in the vertical direction. The outer conductor 40 is fitted into the fitting hole 13.

[0049] like Figure 5 As shown, the fitting groove 14 is formed along the front-to-back direction in the inner peripheral surface of the fitting hole 13. The fitting groove 14 has openings at both the front and back.

[0050] like Figure 5 As shown, the inner cover portion 15 is formed in a cylindrical shape that protrudes forward from the portion of the housing body 12 surrounding the fitting hole 13. The inner cover portion 15 is formed in a cylindrical shape (more specifically, a cylindrical shape) that extends in the front-rear direction. The inner space of the inner cover portion 15 communicates with the fitting hole 13 and is open at the front of the housing 11.

[0051] like Figure 5As shown, the outer cover 16 surrounds the outer periphery of the inner cover 15. The outer cover 16 is formed into a cylindrical shape extending in the front-rear direction. The inner space of the outer cover 16 is open at the front of the housing 11. The front end of the outer cover 16 is positioned further forward than the front end of the inner cover 15.

[0052] like Figure 5 As shown, the locking arm 17 is disposed on the inner side of the outer cover portion 16. The locking arm 17 is shaped to extend in the front-rear direction. The locking arm 17 is supported in such a way that its front end side can swing in the up-down direction. Figure 7 and Figure 8 As shown, the locking arm 17 is supported on the outer cover portion 16. The locking arm 17 is engaged with the opposite-side locking portion 94 of the opposite-side housing 91 in the opposite-side connector 90 (see reference). Figure 5 ).

[0053] like Figure 1 As shown, the first anti-detachment locking portion 18 is shaped to protrude from the outer peripheral surface (left and right sides in this embodiment) of the housing body 12. The first anti-detachment locking portion 18 is provided at the lower end of the housing body 12. The first anti-detachment locking portion 18 can lock the anti-detachment member 73.

[0054] (Summary of inner conductor 20, outer conductor 40, and dielectric 60)

[0055] like Figure 4 As shown, the inner conductor 20 is L-shaped. The inner conductor 20 has a first inner conductor 21 and a second inner conductor 22. The first inner conductor 21 and the second inner conductor 22 are both made of metal and are formed by bending metal plates. The first inner conductor 21 and the second inner conductor 22 are electrically connected to each other.

[0056] like Figure 5 As shown, the outer conductor 40 is L-shaped and surrounds the inner conductor 20. The outer conductor 40 has a first outer conductor 41 and a second outer conductor 42. The first outer conductor 41 and the second outer conductor 42 are both made of metal. The first outer conductor 41 and the second outer conductor 42 are electrically connected to each other.

[0057] Dielectric 60 is insulating and made of synthetic resin. For example... Figure 5 As shown, dielectric 60 is disposed between inner conductor 20 and outer conductor 40. Dielectric 60 has a first dielectric 61 and a second dielectric 62.

[0058] (Structure of the first inner conductor 21)

[0059] The first inner conductor 21 is a plate-shaped component, formed by bending a pair of metal plates. For example... Figure 4 to 6As shown, the first inner conductor 21 has a first inner conductor body 23, a locking portion 24, a stabilizer 25, and a barrel portion 26.

[0060] As shown in Figure 4 , Figure 6 and Figure 10 , the first inner conductor body 23 has a first bottom plate portion 28, a second bottom plate portion 29, a pair of side plate portions 30, a pair of first connecting portions 31, and a pair of inducing portions 32. The first bottom plate portion 28 and the second bottom plate portion 29 are arranged apart from each other in the up-and-down direction. The thickness direction of the first bottom plate portion 28 and the second bottom plate portion 29 is along the front-and-back direction. The pair of side plate portions 30 are formed in a shape that continues to the left and right sides of each of the first bottom plate portion 28 and the second bottom plate portion 29 and protrudes forward. The pair of side plate portions 30 are arranged apart from each other in the left-and-right direction. The pair of first connecting portions 31 extend forward from the front ends of the pair of side plate portions 30. The pair of first connecting portions 31 extend from a part of the front ends of the pair of side plate portions 30 in the up-and-down direction. The minimum interval of the pair of first connecting portions 31 is smaller than the interval of the pair of side plate portions 30. The pair of inducing portions 32 extend forward from the front ends of the pair of first connecting portions 31. The interval of the pair of inducing portions 32 increases as it goes forward.

[0061] As shown in Figure 6 , the locking portion 24 extends in the up-and-down direction. The locking portion 24 is in a double-supported beam shape in which the up-and-down end portions are supported by the first inner conductor body 23. The lower end portion of the locking portion 24 is supported by the upper end portion of the first bottom plate portion 28, and the upper end portion of the locking portion 24 is supported by the lower end portion of the second bottom plate portion 29. The locking portion 24 is in a plate shape and can be flexibly deformed in the front-and-back direction. The thickness direction of the locking portion 24 is along the front-and-back direction. The locking portion 24 protrudes rearward from the first inner conductor body 23. The locking portion 24 is bent. The locking portion 24 has a convex surface 24A that protrudes from the first inner conductor body 23, and a concave surface 24B that is formed on the inner side of the convex surface 24A. That is, the convex surface 24A is formed on the rear surface of the locking portion 24, and the concave surface 24B is formed on the front surface of the locking portion 24.

[0062] As shown in Figure 4 and Figure 10 , the stabilizer 25 is provided at the front end of one of the pair of side plate portions 30 (in this embodiment, the right side plate portion 30). The stabilizer 25 is arranged apart from the pair of first connecting portions 31 in the up-and-down direction. More specifically, the stabilizer 25 is arranged lower than the first connecting portions 31. The stabilizer 25 is bent and protrudes outward in the left-and-right direction.

[0063] As shown in Figure 4 , the barrel portion 26 is crimped to the inner conductor 81 of the electric wire 80 and is electrically connected to the inner conductor 81.

[0064] (Structure of the first outer conductor 41)

[0065] The first outer conductor 41 is a cylindrical component formed by casting or machining. "Formed into a cylindrical shape by casting or machining" refers to the process of forming it into a cylindrical shape through casting or machining, not to bending a machined metal sheet into a cylindrical shape. Furthermore, casting also includes die casting. For example... Figure 5 As shown, the first outer conductor 41 surrounds the first inner conductor 21. Figure 3 and Figure 5 As shown, the first outer conductor 41 has a receiving part 43, a cylindrical part 44, a conductor-side fitting hole 45, a conductor-side fitting groove 46, a first locking part 47, a through hole 48, and a sleeve positioning part 49.

[0066] like Figure 3 and 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.

[0067] 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.

[0068] like Figure 3 and Figure 9 As shown, the first locking part 47 is provided inside the conductor-side fitting hole 45 in the receiving part 43. The first locking parts 47 are provided in pairs on the left and right sides. The first locking part 47 is shaped to protrude inward from the inner circumferential surface of the receiving part 43. 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.

[0069] like Figure 3 and Figure 9As 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.

[0070] 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.

[0071] (Structure of the first dielectric 61)

[0072] 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.

[0073] like Figure 5 As shown, cavity 63 extends in the vertical direction. Cavity 63 opens below the first dielectric 61.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] (Structure of the 2nd inner conductor 22)

[0079] The 2nd inner conductor 22 is a plate-like member formed by bending processing of a metal plate. As shown in Figure 4 and Figure 6 , the 2nd inner conductor 22 extends in the front-rear direction. The 2nd inner conductor 22 has a 2nd inner conductor body 34, an inner conductor side partner connecting portion 35, a 2nd connecting portion 36, an inner conductor side protrusion 37, and a detachment prevention protrusion 38.

[0080] As shown in Figure 4 and Figure 6 , the 2nd inner conductor body 34 is formed in a cylindrical shape (more specifically, a circular cylindrical shape) extending in the front-rear direction.

[0081] As shown in Figure 4 and Figure 6 , the inner conductor side partner connecting portion 35 is disposed on the front side of the 2nd inner conductor body 34. The inner conductor side partner connecting portion 35 is electrically connected to the partner side inner conductor 92 (refer to Figure 5 ) of the partner side connector 90.

[0082] As shown in Figure 4 and Figure 6 , the 2nd connecting portion 36 is disposed on the rear side of the 2nd inner conductor body 34. The 2nd connecting portion 36 is configured as a tab. The 2nd connecting portion 36 protrudes toward the rear of the rear end of the 2nd dielectric body 62. The 2nd connecting portion 36 is electrically connected to the 1st connecting portion 31 of the 1st inner conductor 21.

[0083] As shown in Figure 6 , the inner conductor side protrusion 37 is provided to the outer peripheral surface of the 2nd inner conductor body 34 and protrudes upward from the outer peripheral surface. When the 2nd inner conductor 22 is inserted into the 2nd dielectric body 62, the inner conductor side protrusion 37 is brought into contact with the rear surface of the 2nd dielectric body 62, and the 2nd inner conductor 22 is thereby restricted from moving forward relative to the 2nd dielectric body 62.

[0084] As shown in Figure 9 , the detachment prevention protrusion 38 is provided to both left and right sides of the 2nd inner conductor body 34 and protrudes outward in the left-right direction. The detachment prevention protrusion 38 prevents the 2nd inner conductor 22, which is normally inserted into the 2nd dielectric body 62, from falling backward.

[0085] (Structure of the 2nd outer conductor 42)

[0086] The 2nd outer conductor 42 is a plate-like member formed by bending processing of a metal plate. As shown in Figure 6 , the 2nd outer conductor 42 surrounds the 2nd inner conductor 22. The 2nd outer conductor 42 is formed in a cylindrical shape (more specifically, a circular cylindrical shape) extending in the front-rear direction. The 2nd outer conductor 42 is open in the front-rear direction. As shown in Figure 3As 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.

[0087] like Figure 3 As shown, the outer conductor body 50 is cylindrical (more specifically, circular).

[0088] like Figure 3 and Figure 9 As 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] (Structure of the second dielectric 62)

[0093] like Figure 6As 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).

[0094] (Other structures)

[0095] Figure 5 The sleeve 70 shown is cylindrical (more specifically, cylindrical). The sleeve 70 is, for example, made of metal. Figure 5 The 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.

[0096] (Assembly of connector 10)

[0097] 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.

[0098] 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.

[0099] The first dielectric body 61 is inserted from below to the inside of the first outer conductor 41. When the first dielectric body 61 is inserted to the regular insertion position, the entry hole 65 is disposed in alignment with the conductor-side fitting hole 45 of the first outer conductor 41 in the front-rear direction. The exposed shield layer 83 covers the outer peripheral surface of the cylindrical portion 44 of the first outer conductor 41, and is crimped by the sleeve 70. Thus, the first outer conductor 41 is electrically connected to the shield layer 83 of the electric wire 80.

[0100] The first outer conductor 41 is inserted from below to the inside of the housing main body 12 of the housing 11. When the first outer conductor 41 is inserted to the regular insertion position, the conductor-side fitting hole 45 of the first outer conductor 41 is disposed in alignment with the fitting hole 13 of the housing 11 in the front-rear direction, and the conductor-side fitting groove 46 of the first outer conductor 41 is disposed in alignment with the fitting groove 14 of the housing 11 in the front-rear direction. As shown in FIG. 6, the first locking portion 47 is disposed in a manner facing the rear of the fitting hole 13. After the first outer conductor 41 is inserted, the second anti-removal locking portion 75 of the anti-removal member 73 is locked to the first anti-removal locking portion 18 of the housing 11. Figure 9

[0101] The second inner conductor 22 is inserted from the rear to the inside 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 to the regular insertion position by the inner-conductor-side protrusion 37 and the anti-removal protrusion 38. The second dielectric body 62 is inserted from the rear to the inside 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 in a manner that the protrusion 52 is fitted to the fitting groove 14 of the housing 11 from the front. 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.

[0102] 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 by being flexed. 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.

[0103] ​When the second locking portion 51 is caught in the first locking portion 47, the second outer conductor 42 is linked with the first outer conductor 41. The first outer conductor 41 is configured not to fall out of the housing main body 12 from the fitting hole 13. Therefore, even if the second outer conductor 42 linked with the first outer conductor 41 is pulled in a direction of falling out of 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 of being prevented from falling out in a state where the second locking portion 51 is caught in the first locking portion 47.

[0104] In the course of the second outer conductor 42 being fitted in the conductor-side fitting hole 45 in the housing portion 43, the second connecting portion 36 of the second inner conductor 22 enters the entrance hole 65 of the first dielectric body 61, and advances while spreading the pair of first connecting portions 31. In a state where the second inner conductor 22 is normally connected to the first inner conductor 21, the second inner conductor 22 becomes a state of being 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 arranged 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.

[0105] However, a second outer conductor 42B, which will be described later, separate from the second outer conductor 42 can be fitted in the housing portion 43 of the first outer conductor 41. That is, the connector 10 is a structure of selecting one of a plurality of second outer conductors, and in the case of the present embodiment, selecting either the second outer conductor 42 or the second outer conductor 42B to be linked with the first outer conductor 41. The second outer conductor 42B has an outer conductor main body 50B, a second locking portion 51B, a protrusion 52B, and a counterpart connecting portion 54B.

[0106] The outer conductor main body 50B is formed in a cylindrical shape (more specifically, a circular cylindrical shape) extending in the front-rear direction. The second locking portion 51B is arranged on the rear side of the outer conductor main body 50B.

[0107] 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.

[0108] The protrusion 52B is provided to the outer peripheral surface of the outer conductor main body 50B. The protrusion 52B protrudes upward from the upper end portion of the outer peripheral surface of the outer conductor main body 50B. The protrusion 52B is formed in the same shape as the protrusion 52.

[0109] The counterpart connecting portion 54B is formed in a shape of a cantilever supported to the front end of the outer conductor main body 50B and protruding 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 capable of being flexibly deformed. The counterpart connecting portion 54B is connected to the counterpart-side outer conductor 93 (refer to FIG. 6) of the counterpart-side connector 90.Figure 5 ) elastic contact ground connection. The counterpart connecting portion 54B has an induction surface 56B that induces the counterpart side outer conductor 93 when connected to the counterpart side outer conductor 93.

[0110] The induction surface 56B is formed at the front end of the counterpart connecting portion 54B. The induction surface 56B is inclined toward the radial inner side as it goes toward the rear. The induction surface 56B induces the counterpart side outer conductor 93 toward 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.

[0111] That is, the second locking portion 51 and the second locking portion 51B are formed in the same shape as each other and in a shape that is locked in the first locking portion 47, respectively. Therefore, when the second outer conductor 42 selected from among the second outer conductors 42 and 42B is fitted into 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 in a shape that is connected to the counterpart side connecting portion in a different shape from each other. Therefore, it is possible to fit the counterpart connector corresponding to the second outer conductor linked to the first outer conductor 41 into the connector 10.

[0112] (Effect of the connector 10)

[0113] The connector 10 can form the first outer conductor 41 in a manner in which a gap is less likely to occur because the first outer conductor 41 is a member formed in a cylindrical shape by casting or cutting, and as a result, the shielding performance of the first outer conductor 41 can be improved.

[0114] Here, in the case where the second outer conductor 42 is also a member formed in a cylindrical shape by casting or cutting, both the first outer conductor 41 and the second outer conductor 42 are less likely to be deformed, and therefore it is considered that they are linked to each other by press-fitting. However, in the case where they are linked by press-fitting, when it is necessary to ensure electrical connection reliability, the dimensional tolerance of the first outer conductor 41 and the second outer conductor 42 becomes small, and it can become 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 being flexed. Therefore, the second locking portion 51 is locked in the first locking portion 47 of the first outer conductor 41 by being deformed by being flexed, 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 becomes easy to manufacture, and it is possible to achieve a state in which the electrical connection reliability is high. In addition, by making the second outer conductor 42 a plate shape, it is possible to manufacture it at a low cost.

[0115] Further, since a part of the second outer conductor 42 enters the housing portion 43, thinness of the connector 10 in the direction in which the second outer conductor 42 protrudes from the first outer conductor 41 can be achieved.

[0116] Further, the second locking portion 51 of the second outer conductor 42 is disposed at a position at which the penetration hole 48 is blocked in a state in which the second outer conductor 42 is fitted to the housing portion 43. Therefore, a decrease in the shielding performance of the outer conductor 40 can be suppressed.

[0117] 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, since the second outer conductor 42 is a plate-shaped member, the counterpart connecting portion 54 that elastically contacts can be easily formed.

[0118] Further, the connector 10 is a structure in which any one of a plurality of second outer conductors 42, 42B is selected and connected to the first outer conductor 41, and the plurality of second outer conductors 42, 42B have counterpart connecting portions 54, 54B that differ in shape 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.

[0119] Further, the connector 10 is latched to the latching hole 64 by the latching portion 24, and thus a decrease in the impedance of the first inner conductor 21 can be suppressed. Further, the latching portion 24 is in 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 this connector 10, compared to a structure in which the latching portion is a lance-shaped portion, a decrease in the impedance of the first inner conductor 21 can be suppressed.

[0120] 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.

[0121] Further, the latching hole 64 and the entry hole 65 of the first dielectric body 61 are disposed coaxially with each other with the cavity 63 interposed therebetween. Therefore, when the connector 10 is manufactured, the same mold in a straight line shape that forms the latching hole 64 and the entry hole 65 can be used to simultaneously release the mold.

[0122] Further, in the state where the second inner conductor 22 is normally connected to the first inner conductor 21, the tip of the second connecting portion 36 of the second inner conductor 22 is disposed inside the concave surface 24B. Therefore, in the case where the first inner conductor 21 is in the half-inserted state, the tip of the second connecting portion 36 comes into contact with the first inner conductor 21. Therefore, it is possible to easily determine whether the first inner conductor 21 is in the half-inserted state. In particular, in the present embodiment, in the state where the tip 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 caught by the first locking portion 47 of the first outer conductor 41. Therefore, according to the non-catching, it is possible to more simply determine that the first inner conductor 21 is in the half-inserted state.

[0123] Further, a guide groove 66 is formed in the inner circumferential surface of the cavity 63, and the guide groove 66 is formed along the up-and-down direction and is continuous with the catching hole 64. Therefore, the connector 10 can guide the catching portion 24 of the first inner conductor 21 inserted into the cavity 63 to the catching hole 64 using the guide groove 66.

[0124] Further, the first locking portion 47 of the connector 10 is disposed so as to face the inner side of the fitting direction of the second outer conductor 42 in the fitting hole 13 in the state where the first outer conductor 41 is disposed in the normally inserted position. Also, the second locking portion 51 is caught by the first locking portion 47. In the state where the second locking portion 51 is caught by the first locking portion 47, the second outer conductor 42 is disposed in the fitting hole 13 in a manner that is prevented from being removed. On the contrary, 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 therefore the second locking portion 51 is not caught by the first locking portion 47, and the second outer conductor is removed from the fitting hole. Therefore, according to the connector 10, it is possible to suppress the catching of the first outer conductor 41 and the second outer conductor 42 in the case of the half-inserted state.

[0125] 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. Therefore, the connector 10 can perform positioning of the second outer conductor 42 with respect to the circumferential direction of the housing 11.

[0126] 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 caught by the housing 11, and therefore 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. Therefore, according to this structure, it is easy to confirm whether the first outer conductor 41 and the second outer conductor 42 are properly connected.

[0127] Further, the protrusion 52 of the second outer conductor 42 is fitted into the conductor-side fitting groove 46 of the first outer conductor 41 in the state where the second locking portion 51 is locked to the first locking portion 47, so that the positioning of the second outer conductor 42 in the circumferential direction of the first outer conductor 41 can be performed.

[0128] 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-side 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 intersecting (more specifically, orthogonal to) the extending direction of the first outer conductor 41. Therefore, the connector 10 can change the path in a direction intersecting the extending direction of the electric wire 80.
