[0027] [Description of embodiments of this disclosure]
[0028] First, the implementation methods of this disclosure are listed and explained.
[0029] The connector disclosed herein,
[0030] (1) It has an inner conductor and an outer conductor surrounding the inner conductor, the outer conductor having: a first outer conductor electrically connected to the shielding layer of the wire; and a second outer conductor electrically connected to the first outer conductor and electrically connected to the opposite-side outer conductor of the opposite-side connector, the first outer conductor being formed into a cylindrical member by casting or machining and having a first locking part, the second outer conductor being a plate-shaped member and having a second locking part that engages with the first locking part.
[0031] According to this connector, because 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.
[0032] In this case, where the second outer conductor is also formed into a cylindrical component by casting or machining, both the first and second outer conductors are not easily deformed. Therefore, a press-fit connection is considered. However, with a press-fit connection, the dimensional tolerances of the first and second outer conductors become smaller when ensuring reliable electrical connection, potentially making the manufacture of the outer conductors difficult. In this regard, according to this connector, the second outer conductor is a plate-shaped component with a second locking part that can be flexibly deformed. Therefore, by flexing and deforming the second locking part to engage with the first locking part of the first outer conductor, the dimensional tolerances of the first and second outer conductors are maximized, making the manufacture of the outer conductors easier and achieving a connection with high electrical connection reliability. Furthermore, by making the second outer conductor plate-shaped, it can be manufactured inexpensively.
[0033] Furthermore, when manufacturing multiple connectors in correspondence with multiple counterpart connectors, by preparing multiple second outer conductors in advance in correspondence with the types of counterpart outer conductors of the counterpart connectors, it is possible to manufacture multiple connectors that use the first outer conductor as a common component and can be fitted with multiple counterpart outer conductors.
[0034] (2) Preferably, the connector is a structure that selects any one of the various second outer conductors to connect with the first outer conductor, and the various second outer conductors have connecting portions with different shapes from each other.
[0035] Based on this structure, it is possible to manufacture various connectors that use the first outer conductor as a common component and can be fitted with various opposite outer conductors.
[0036] [Details of the embodiments of this disclosure]
[0037] The following is a reference to the appendix. Figure 1 Specific examples of this disclosure will be described below.

[0052] (Summary of inner conductor 20, outer conductor 40, and dielectric 60)
[0053] 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.
[0054] 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.
[0055] 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.
[0056] (Structure of the first inner conductor 21)
[0057] The first inner conductor 21 is a plate-shaped component, formed by bending a pair of metal plates. For example... Figures 4-6 As shown, the first inner conductor 21 is shaped to extend in the vertical direction. The first inner conductor 21 has a first inner conductor body 23, a locking portion 24, a stabilizer 25, and a cylindrical portion 26.
[0058] like Figure 4 , Figure 6 as well as Figure 10 As shown, the first inner conductor body 23 has a first base plate portion 28, a second base plate portion 29, a pair of side plate portions 30, a pair of first connecting portions 31, and a pair of guide portions 32. The first base plate portion 28 and the second base plate portion 29 are arranged at intervals in the vertical direction. The thickness direction of the first base plate portion 28 and the second base plate portion 29 is along the front-rear direction. The pair of side plate portions 30 are formed to be continuous with the left and right sides of the first base plate portion 28 and the second base plate portion 29 and protrude forward. The pair of side plate portions 30 are arranged at intervals in the left and right direction. The pair of first connecting portions 31 extend forward from the front end of the pair of side plate portions 30. The pair of first connecting portions 31 extend from a portion of the front end of the pair of side plate portions 30 in the vertical direction. The minimum interval between the pair of first connecting portions 31 is smaller than the interval between the pair of side plate portions 30. The pair of guide portions 32 extend forward from the front end of the pair of first connecting portions 31. The spacing between the pair of inductors 32 increases as they face forward.
[0059] like Figure 6 As shown, the locking portion 24 extends in the vertical direction. The locking portion 24 is in the shape of a double-support beam, with its upper and lower ends supported by the first inner conductor body 23. The lower end of the locking portion 24 is supported by the upper end of the first base plate portion 28, and the upper end of the locking portion 24 is supported by the lower end of the second base plate portion 29. The locking portion 24 is plate-shaped and can flex and deform in the forward and backward direction. The thickness direction of the locking portion 24 is along the forward and backward direction. The locking portion 24 extends rearward from the first inner conductor body 23. The locking portion 24 is curved. The locking portion 24 has a convex surface 24A extending from the first inner conductor body 23 and a concave surface 24B 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.
[0060] like Figure 4 and Figure 10As shown, the stabilizer 25 is disposed at the front end of one of the pair of side plate portions 30 (the right side plate portion 30 in this embodiment). The stabilizer 25 is arranged at a vertical distance from the pair of first connecting portions 31. More specifically, the stabilizer 25 is disposed below the first connecting portions 31. The stabilizer 25 protrudes outward in a left-right direction.
[0061] like Figure 4 As shown, the cylindrical portion 26 is crimped to the inner conductor 81 of the wire 80 and is electrically connected to the inner conductor 81.
[0062] (Structure of the first outer conductor 41)
[0063] 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.
[0064] 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.
[0065] 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.
[0066] like Figure 3 and Figure 9As 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.
[0067] 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.
[0068] 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.
[0069] (Structure of the first dielectric 61)
[0070] 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.
[0071] like Figure 5 As shown, cavity 63 extends in the vertical direction. Cavity 63 opens below the first dielectric 61.
[0072] 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.
[0073] 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.
[0074] like Figure 6As 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.
[0075] 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.
[0076] (Structure of the second inner conductor 22)
[0077] 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.
[0078] 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.
[0079] like Figure 4 and Figure 6 As 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.
[0080] 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.
[0081] 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.
[0082] like Figure 9As 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.
[0083] (Structure of the second outer conductor 42)
[0084] 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.
[0085] like Figure 3 As shown, the outer conductor body 50 is cylindrical (more specifically, circular).
[0086] 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.
[0087] 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.
[0088] 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.
[0089] 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 5The 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.
[0090] (Structure of the second dielectric 62)
[0091] 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).
[0092] (Other structures)
[0093] 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.
[0094] (Assembly of connector 10)
[0095] 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.
[0096] 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.
[0097] 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.
[0098] The first outer conductor 41 is inserted into the housing body 12 of the housing 11 from below. When the first outer conductor 41 is inserted into the correct insertion position, the conductor-side fitting hole 45 of the first outer conductor 41 and the fitting hole 13 of the housing 11 are arranged in a front-back direction, and the conductor-side fitting groove 46 of the first outer conductor 41 and the fitting groove 14 of the housing 11 are arranged in a front-back direction. Figure 9 As shown, the first locking part 47 is arranged facing the rear of the fitting hole 13. After the first outer conductor 41 is inserted, the second anti-disengagement locking part 75 of the anti-disengagement member 73 is locked onto the first anti-disengagement locking part 18 of the housing 11.
[0099] The second inner conductor 22 is inserted into the inner side of the second dielectric 62 from the rear. When the second inner conductor 22 is inserted into the correct insertion position, its movement relative to the front-rear direction of the second dielectric 62 is restricted by the inner conductor-side protrusion 37 and the anti-dislodgement protrusion 38. The second dielectric 62 is inserted into the inner side of the second outer conductor 42 from the rear. The second dielectric 62 is restricted from moving forward by contacting the front stop 53 of the second outer conductor 42. The second outer conductor 42 engages with the engagement hole 13 of the housing 11 from the front with its protrusion 52 engaging with the engagement groove 14 of the housing 11. As the engagement of the second outer conductor 42 progresses further, the second outer conductor 42 engages with the conductor-side engagement hole 45 of the first outer conductor 41, and the protrusion 52 of the second outer conductor 42 engages with the conductor-side engagement groove 46 of the first outer conductor 41.
[0100] During the engagement of the second outer conductor 42 with the conductor-side fitting hole 45 in the receiving part 43, the second locking part 51 is pressed by the first locking part 47 and deformed inward. As the engagement progresses further, the first locking part 47 is inserted into the locking hole 55 of the second locking part 51, and the second locking part 51 returns to its original shape through its own elastic restoring force. Thus, the second locking part 51 is locked in place by the first locking part 47.
[0101] When the second locking part 51 is engaged with the first locking part 47, the second outer conductor 42 is connected to the first outer conductor 41. The first outer conductor 41 is configured not to detach from the housing body 12 into the fitting hole 13. Therefore, even if the second outer conductor 42, which is connected to the first outer conductor 41, is pulled in a direction that would cause it to detach from the fitting hole 13, the first outer conductor 41 remains hooked within the housing body 12. In other words, the second outer conductor 42 is positioned in the fitting hole 13 in an anti-detachment manner with the second locking part 51 engaged with the first locking part 47.
[0102] During the engagement of the second outer conductor 42 with the conductor-side fitting hole 45 in the receiving portion 43, the second connecting portion 36 of the second inner conductor 22 enters the entry hole 65 of the first dielectric 61, advancing while widening the pair of first connecting portions 31. When the second inner conductor 22 and the first inner conductor 21 are properly connected, the second inner conductor 22 is sandwiched between the pair of first connecting portions 31 of the first inner conductor 21, and the tip of the second connecting portion 36 of the second inner conductor 22 is positioned inside the concave surface 24B. At this time, the tip of the second connecting portion 36 of the second inner conductor 22 does not contact the concave surface 24B.
[0103] However, the second outer conductor 42B, which is separate from the second outer conductor 42 and will be described later, can be fitted into the receiving portion 43 of the first outer conductor 41. That is, the connector 10 is a structure that selects from various second outer conductors, and in this embodiment, selects either the second outer conductor 42 or the second outer conductor 42B to connect with 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 connecting portion 54B for the opposite side.
[0104] The outer conductor body 50B is formed in a cylindrical shape (more specifically, a cylindrical shape) extending in the front-to-back direction. The second locking part 51B is disposed on the rear side of the outer conductor body 50B.
[0105] The second locking part 51B is provided on the left and right sides of the second outer conductor 42B. A second locking hole 55B is formed in the second locking part 51B. The second locking part 51B has the same shape as the second locking part 51.
[0106] A protrusion 52B is provided on the outer peripheral surface of the outer conductor body 50B. The protrusion 52B protrudes upward from the upper end of the outer peripheral surface of the outer conductor body 50B. The protrusion 52B has the same shape as the protrusion 52.
[0107] The connecting portion 54B is cantilevered and supported at the front end of the outer conductor body 50B, protruding forward. Multiple connecting portions 54B are provided at equal intervals in the circumferential direction (six in this embodiment). The connecting portion 54B is flexible and deformable. The connecting portion 54B connects to the outer conductor 93 of the opposite side connector 90 (see reference). Figure 5 The flexible contact grounding connection is provided. The connecting part 54B for the other party has an induction surface 56B that induces the other party's outer conductor 93 when connected to it.
[0108] A guiding surface 56B is formed at the front end of the counterpart connection portion 54B. The guiding surface 56B is inclined radially inward as it faces rearward. The guiding surface 56B guides the counterpart outer conductor 93 radially inward toward the counterpart connection portion 54B. The radially inward side of the counterpart connection portion 54B is electrically connected to the counterpart outer conductor 93.
[0109] In other words, the second locking part 51 and the second locking part 51B are identical in shape and are respectively locked to the first locking part 47. Therefore, when the selected second outer conductor 42 or the second outer conductor 42B is engaged with the receiving part 43 of the first outer conductor 41, the second locking part of the engaged second outer conductor is locked to the first locking part 47 of the first outer conductor 41, and the second outer conductor is connected 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 connection part 54 and the counterpart connection part 54B are different in shape and are connected to the counterpart side connection part with a different shape. Therefore, the counterpart side connector corresponding to the second outer conductor connected to the first outer conductor 41 can be engaged to the connector 10.
[0110] (Effect of connector 10)
[0111] Since the first outer conductor 41 of the connector 10 is formed into a cylindrical component by casting or machining, the first outer conductor 41 can be formed in a way that does not easily produce gaps, thereby improving the shielding performance of the first outer conductor 41.
[0112] Here, when the second outer conductor 42 is also formed into a cylindrical component by casting or machining, both the first outer conductor 41 and the second outer conductor 42 are not easily deformed, so a press-fit connection is considered. However, in the case of a press-fit connection, when ensuring reliable electrical connection, the dimensional tolerances of the first outer conductor 41 and the second outer conductor 42 become smaller, potentially making the manufacture of the outer conductor 40 difficult. In this regard, according to the connector 10, the second outer conductor 42 is a plate-shaped component with a second locking portion 51 that can be flexibly deformed. Therefore, by flexing and deforming the second locking portion 51 to lock against the first locking portion 47 of the first outer conductor 41, the dimensional tolerances of the first outer conductor 41 and the second outer conductor 42 are obtained more readily, making the manufacture of the outer conductor 40 easier and achieving a connection with high electrical connection reliability. In addition, by making the second outer conductor 42 plate-shaped, it can be manufactured inexpensively.
[0113] Furthermore, since a portion of the second outer conductor 42 enters the receiving portion 43, the connector 10 can be made thinner in the protruding direction of the second outer conductor 42 protruding from the first outer conductor 41.
[0114] Furthermore, the second locking part 51 of the second outer conductor 42 is positioned to block the through hole 48 when the second outer conductor 42 is engaged with the receiving part 43. Therefore, the reduction in the shielding performance of the outer conductor 40 can be suppressed.
[0115] Furthermore, the second outer conductor 42 has a mating connection portion 54 that contacts the mating outer conductor of the mating connector 90. Therefore, the connector 10 can improve the electrical connection reliability between the second outer conductor 42 and the mating outer conductor 93. Additionally, because the second outer conductor 42 is a plate-shaped component, the mating connection portion 54 with elastic contact can be easily formed.
[0116] Furthermore, the connector 10 is a structure in which any of a variety of second outer conductors 42, 42B are selected to connect with the first outer conductor 41, and the various second outer conductors 42, 42B have connecting portions 54, 54B of different shapes to each other. Therefore, it is possible to manufacture various connectors that use the first outer conductor 41 as a common component and can be fitted with various opposing outer conductors.
[0117] Furthermore, the connector 10 is secured to the locking hole 64 by the locking portion 24, thereby preventing the first inner conductor 21 from detaching from the first dielectric 61. Moreover, the locking portion 24 is in the shape of a double-support beam with its upper and lower ends supported by the first inner conductor body 23. Therefore, according to this connector 10, compared to a structure where the locking portion is spear-shaped, the impedance reduction of the first inner conductor 21 can be suppressed.
[0118] Furthermore, the locking portion 24 is bent. Therefore, the connector 10 can reduce the insertion force when inserting the first inner conductor 21 into the inside of the first dielectric 61.
[0119] Furthermore, the locking hole 64 and the entry hole 65 of the first dielectric 61 are coaxially arranged with respect to each other across the cavity 63. Therefore, when manufacturing the connector 10, it can be simultaneously demolded using the same mold that forms the straight line of the locking hole 64 and the entry hole 65.
[0120] Furthermore, when the second inner conductor 22 and the first inner conductor 21 are properly connected, the top end of the second connecting portion 36 of the second inner conductor 22 is disposed inside the concave surface 24B. Therefore, when the first inner conductor 21 is in a semi-inserted state, the top end of the second inner conductor 22 touches the first inner conductor 21. Therefore, it is easy to determine whether the first inner conductor 21 is in a semi-inserted state. In particular, in this embodiment, when the top end of the second inner conductor 22 touches the first inner conductor 21, the second locking portion 51 of the second outer conductor 42 does not lock against the first locking portion 47 of the first outer conductor 41. Therefore, based on the fact that it does not lock, it is easier to determine whether the first inner conductor 21 is in a semi-inserted state.
[0121] Furthermore, a guide groove 66 is formed on the inner circumferential surface of the cavity 63. The guide groove 66 is formed in the vertical direction and is connected to the locking hole 64. Therefore, the connector 10 can use the guide groove 66 to guide the locking portion 24 of the first inner conductor 21 inserted into the cavity 63 towards the locking hole 64.
[0122] Furthermore, when the first outer conductor 41 is in the normal insertion position, the first locking part 47 of the connector 10 is positioned inwards towards the engagement direction of the second outer conductor 42 in the engagement hole 13. The second locking part 51 engages with the first locking part 47. With the second locking part 51 engaged with the first locking part 47, the second outer conductor 42 is positioned within the engagement hole 13 in a way that prevents it from disengaging. Conversely, when the first outer conductor 41 is in a partially inserted state, the positions of the second locking part 51 and the first locking part 47 are offset, so the second locking part 51 does not engage with the first locking part 47, and the second outer conductor disengages from the engagement hole. Therefore, according to this connector 10, it is possible to prevent the first outer conductor 41 and the second outer conductor 42 from engaging in the partially inserted state.
[0123] Furthermore, 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 protrusion 52 that engages with the fitting groove 14 during fitting relative to the first outer conductor 41. Therefore, the connector 10 can position the second outer conductor 42 circumferentially relative to the housing 11.
[0124] Furthermore, the housing 11 is L-shaped, and the first outer conductor 41 and the second outer conductor 42 do not have a housing locking part that locks them into the housing 11. Therefore, the first outer conductor 41 and the second outer conductor 42 can easily detach from the housing 11 when 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 correctly connected.
[0125] Furthermore, when the second locking part 51 is locked in the first locking part 47, the protrusion 52 of the second outer conductor 42 engages with the conductor-side fitting groove 46 of the first outer conductor 41, thus enabling circumferential positioning of the second outer conductor 42 relative to the first outer conductor 41.
[0126] Furthermore, the shielding layer 83 of the 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 opposite-side outer conductor 93 of the opposite-side connector 90 is electrically connected to the second outer conductor 42. Moreover, the second outer conductor 42 extends in a direction that intersects (more specifically, orthogonally) the extending direction of the first outer conductor 41. Therefore, the connector 10 allows the path to change in a direction that intersects the extending direction of the wire 80.
