[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. The connector device of the present disclosure comprises: (1) A connector device includes a first connector having a first terminal portion and mounted on a first circuit board, a second connector having a second terminal portion and mounted on a second circuit board, and an adapter having a pair of connection ends, the first terminal portion and the second terminal portion have contact portions having mutually symmetrical shapes, the pair of connection ends are capable of contacting the contact portions, and are symmetrical with respect to a direction in which the first terminal portion and the second terminal portion face each other, the first terminal portion includes a first dielectric surrounding a first inner conductor, the second terminal portion includes a second dielectric surrounding a second inner conductor, and the first dielectric and the second dielectric are the same component. According to the configuration of the present disclosure, since the pair of connection ends provided on the adapter are symmetrical, it is not necessary to check the orientation of the adapter when connecting the adapter to the first end or the second terminal portion. Therefore, the connector device of the present disclosure has excellent workability during assembly.

[0010] (2) It is preferable that the adapter has a movable inner conductor, a movable dielectric that houses the movable inner conductor, and a movable outer conductor that surrounds the movable dielectric, and that the movable dielectric is exposed on the end face of the connection end. With this configuration, when connecting the connection end of the adapter to the first terminal portion or the second terminal portion, the movable dielectric can be pressed and operated, which improves workability.

[0011] (3) The adapter preferably has a movable dielectric and a cylindrical movable outer conductor surrounding the movable dielectric, a locking groove is formed on the outer periphery of the movable dielectric, an elastically deformable locking claw is formed on the movable outer conductor obliquely protruding toward the inner periphery, and the relative displacement between the movable dielectric and the movable outer conductor is restricted by the locking claw being locked in the locking groove. According to this configuration, in the process of assembling the movable outer conductor to the movable dielectric, the locking claw slides against the outer periphery of the movable dielectric in an elastically deformed state. When the movable outer conductor is assembled to the movable dielectric, the locking claw elastically returns to its original state and is locked in the locking groove, thereby holding the movable dielectric and the movable outer conductor in an assembled state.

[0012] (4) In (3), it is preferable that the pair of locking grooves is formed at two locations spaced apart in the axial direction on the outer peripheral surface of the movable dielectric, the pair of locking claws is arranged spaced apart in the axial direction, and the pair of locking claws protrude obliquely toward the mating locking claw. According to this configuration, in the process of assembling the movable outer conductor to the movable dielectric, the locking claw at the front in the assembling direction passes through the locking groove at the front side in the assembling direction. When the movable outer conductor is assembled to the movable dielectric, the pair of locking claws elastically return to their original position and are individually locked in the pair of locking grooves. Since the pair of locking claws lock in the movable dielectric in opposite directions, the relative displacement of the movable outer conductor and the movable dielectric in two directions, forward and reverse, along the axis is restricted.

[0013] (5) In (3) or (4), it is preferable that the outer peripheral surface of the movable dielectric is formed with a tapered sliding surface that is inclined so that the opposing distance between the inner peripheral surface of the movable outer conductor and the movable dielectric gradually increases toward the connection end. According to this configuration, in the process of assembling the movable outer conductor to the movable dielectric, the locking claws come into sliding contact with the tapered sliding surface, so that there is no risk of the protruding end of the locking claws getting caught on the outer peripheral surface of the movable dielectric.

[0014] (6) In (5), it is preferable that the movable outer conductor has an elastic arm portion that is connected to the first terminal portion or the second terminal portion in a state where it is elastically displaced toward the inner circumference, and the elastic arm portion is disposed in a region facing the tapered sliding surface. With this configuration, the space between the tapered sliding surface and the elastic arm portion functions as a deflection space for allowing the elastic displacement of the elastic arm portion, so that the outer diameter dimension of the movable outer conductor can be kept small.

[0015] In the above configurations (7) and (6), it is preferable that the locking claw is formed in a region different from the elastic arm portion. With this configuration, the rigidity of the elastic arm portion is not reduced by forming the locking claw, and therefore the connection reliability of the elastic arm portion to the first terminal portion and the second terminal portion is high.

[0016] [Details of the embodiment of the present disclosure] [Example 1] A first embodiment of the connector device A of the present disclosure will be described with reference to Figs. 1 to 13. The present invention is not limited to these examples, but is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In this first embodiment, the front and rear directions are defined as the diagonally lower right direction in Figs. 1 to 3. The up and down directions are defined as the directions shown in 1 to 5 and 7 as the upward and downward directions. The left and right directions are defined as the diagonally lower left direction in Figs. 1 to 3.

[0017] As shown in FIG. 7, the connector device A of this embodiment has a first connector 10 mounted on a first circuit board B, a second connector 30 mounted on a second circuit board C, and an adapter 50. The first circuit board B is provided, for example, on a shark fin antenna (not shown) attached to the roof (not shown) of an automobile. The first circuit board B is arranged horizontally with the mounting surface facing downward, i.e., toward the inside of the automobile. The second circuit board C is provided, for example, on an ECU attached to the roof of the automobile, and is arranged horizontally with the mounting surface facing upward, i.e., toward the shark fin antenna. The first circuit board B and the second circuit board C are arranged in a positional relationship in which the mounting surfaces of both are parallel and opposed to each other.

[0018] The first connector 10 and the second connector 30 are electrically connected to each other by bringing the first circuit board B close to the second circuit board C. By connecting the two connectors 10, 30, the first circuit board B and the second circuit board C are connected without a wire harness, and high-speed communication is possible between the first circuit board B and the second circuit board C. Since the assembly tolerance between the roof and the shark fin antenna is relatively large at the mounting portion of the shark fin antenna on the roof of the automobile, a positional deviation may occur between the first circuit board B and the second circuit board C in the horizontal direction intersecting with the fitting direction of the two connectors 10, 30. The connector device A of this embodiment is designed to be able to connect the two connectors 10, 30 while absorbing the positional deviation between the two circuit boards B, C.

[0019] 7, the first connector 10 includes a first housing 11 and a plurality of first terminal portions 16. When the first connector 10 is mounted on a first circuit board B, the upper surface of the first housing 11 is fixed to the first circuit board B, and upper ends of the plurality of first terminal portions 16 are connected to a printed circuit (not shown) of the first circuit board B. The first housing 11 is a single component made of synthetic resin and includes a rectangular first terminal holding portion 12, a square cylindrical interference avoidance portion 75, and a rectangular guiding portion 14.

[0020] The first terminal holding portion 12 is formed with a plurality of first terminal accommodating chambers 13 that penetrate the first terminal holding portion 12 in the vertical direction. The first terminal accommodating chambers 13 open to a front surface 12S (lower surface) of the first terminal holding portion 12. When viewed from below the first connector 10, the first terminal accommodating chambers 13 are circular. The multiple first terminal accommodating chambers 13 are arranged so as to be aligned in the front-rear and left-right directions.

[0021] A tapered guide surface 76 is formed on the opening edge of the first terminal accommodating chamber 13 on the front surface 12S of the first terminal holding portion 12 to guide a tip portion 50T of an adapter 50 (described later) into the first terminal accommodating chamber 13. The radius of curvature of the guide surface 76 on the front surface 12S of the first terminal holding portion 12 is greater than ½ the pitch between adjacent first terminal accommodating chambers 13. Therefore, a partition wall portion 77 separating adjacent first terminal accommodating chambers 13 is recessed in an arc shape with respect to the front surface 12S of the first terminal holding portion 12.

[0022] The interference avoidance portion 75 protrudes downward from the outer peripheral edge of the front surface 12S of the first terminal holding portion 12 at a right angle to the front surface 12S. The interference avoidance portion 75 is continuous around the entire circumference of the first terminal holding portion 12. In a bottom view, the interference avoidance portion 75 surrounds all of the first terminal accommodating chambers 13. The inner peripheral surface of the interference avoidance portion 75 is a surface parallel to the direction in which the first connector 10 and the second connector 30 face each other.

[0023] The guiding portion 14 is located below (on the second connector 30 side) the front surface 12S of the first terminal holding portion 12. The base end 14P (upper end) of the guiding portion 14 is continuous around the entire circumference of the lower end edge of the interference avoiding portion 75. The guiding portion 14 is composed of four inclined wall portions that are inclined so as to widen obliquely downward from the lower end edge of the interference avoiding portion 75. In other words, the guiding portion 14 extends in a tapered shape from the base end 14P (upper end) of the guiding portion 14 toward the tip end 14T (lower end).

[0024] The guiding portion 14 is continuous around the entire circumference of the first terminal holding portion 12. In a bottom view, the guiding portion 14 surrounds all of the first terminal accommodating chambers 13. Within the first housing 11, a space below the front surface 12S of the first terminal holding portion 12 that is surrounded by the interference avoidance portion 75 and the guiding portion 14 functions as a first swing space 15. The first swing space 15 is open downwardly of the first housing 11.

[0025] A plurality of first terminal portions 16 are individually accommodated in the plurality of first terminal accommodating chambers 13. As shown in Figs. 12 and 13, the first terminal portion 16 includes a first inner conductor 17 made of metal, a first dielectric 21 made of synthetic resin, and a first outer conductor 22 made of metal. The first inner conductor 17 is cylindrical with its axis parallel to the fitting direction of the two connectors 10, 30. The first inner conductor 17 has a small diameter portion 18, a claw portion 19 protruding radially from the outer periphery of the small diameter portion 18, and a large diameter portion 20 having a diameter larger than that of the small diameter portion 18. The small diameter portion 18 and the large diameter portion 20 are connected in the axial direction. The first dielectric 21 is disk-shaped with a central hole. The first outer conductor 22 is cylindrical with its axis parallel to the first inner conductor 17 and the first dielectric 21.

[0026] The first terminal portion 16 has a configuration in which the small diameter portion 18 of the first inner conductor 17 is coaxially surrounded by the first dielectric 21, and the first inner conductor 17 and the first dielectric 21 are coaxially surrounded by the first outer conductor 22. The first dielectric 21 is located at the upper end of the first outer conductor 22. The space below the first dielectric 21 in the first outer conductor 22 functions as a connection space 23 that is open downward. In the connection space 23, the large diameter portion 20 of the first inner conductor 17 protrudes downward. Each connection space 23 communicates with the first oscillation space 15. The first inner conductor 17 is disposed only in a region behind (above) the inner end 76E (upper end) of the guide surface 76.

[0027] 2, the second connector 30 includes a second housing 31, a plurality of second terminal portions 43, the same number as the first terminal portions 16, and a plurality of adapters 50, the same number as the second terminal portions 43. When the second connector 30 is mounted on the second circuit board C, the lower surface of the second housing 31 is fixed to the second circuit board C, and the lower ends of the plurality of second terminal portions 43 are connected to a printed circuit (not shown) of the second circuit board C. The second housing 31 is a single component made of synthetic resin and has a rectangular second terminal holding portion 32, a rectangular peripheral wall portion 34, and a pair of holding protrusions 40 that are symmetrical on the left and right.

[0028] The second terminal holding portion 32 is formed with a plurality of second terminal accommodating chambers 33, the same number as the second terminal portions 43. The second terminal accommodating chambers 33 are formed to vertically penetrate the second terminal holding portion 32. In a plan view of the second connector 30 seen from above, the second terminal accommodating chambers 33 are circular. The second terminal accommodating chambers 33, like the first terminal accommodating chambers 13, are arranged to be aligned in the front-rear and left-right directions.

[0029] As shown in FIG. 2, the peripheral wall portion 34 protrudes upward from the outer periphery at the upper end of the second terminal holding portion 32 in parallel with the fitting direction of the two connectors 10, 30. In a plan view, the peripheral wall portion 34 surrounds all of the second terminal accommodating chambers 33. A space in the second housing 31 above the second terminal holding portion 32, which is partitioned by the peripheral wall portion 34, functions as a second swing space 35. The second swing space 35 is open to the upper side of the second housing 31, i.e., toward the first connector 10. A notch 37 is formed in each of the left and right side wall portions 36 constituting the peripheral wall portion 34. The notch 37 is cut out in a substantially rectangular shape downward from the upper end edge of the side wall portion 36.

[0030] The side walls 36 are formed with support walls 38 that cover the notches 37 from the outside in the left-right direction. Both front and rear ends of the support walls 38 are bent and connected to the outer surfaces of the side walls 36. The space partitioned by the support walls 38 functions as a holding space 39 that communicates with the second swing space 35 via the notches 37. The inner surfaces of the left and right support walls 38 are formed with holding protrusions 40. The holding protrusions 40 protrude into the holding space 39 from the center of the support walls 38 in the front-back direction. As shown in FIG. 5, the upper surface of the holding protrusions 40 is formed with a guide slope 41 that slopes downward from the support wall 38 side toward the second swing space 35 side. The lower surface of the holding protrusion 40 functions as a fixed side opposing surface 42 that intersects with the fitting direction of the two connectors 10, 30.

[0031] As shown in FIG. 7, a plurality of second terminals 43 are individually accommodated in the plurality of second terminal accommodating chambers 33. As shown in FIGS. 5 and 8, the second terminal 43 includes a second inner conductor 44 made of metal, a second dielectric 45 made of synthetic resin, and a second outer conductor 46 made of metal. The second inner conductor 44 is the same part as the first inner conductor 17, and has a small diameter portion 18, a claw portion 19, and a large diameter portion 20. The second inner conductor 44 is disposed in the opposite direction to the first inner conductor 17 in the axial direction. The second dielectric 45 is the same part as the first dielectric 21, and is disposed in the opposite direction to the first dielectric 21 in the axial direction. The second outer conductor 46 is cylindrical with its axis parallel to the second inner conductor 44 and the second dielectric 45. The contact portion of the second terminal 43 with the adaptor 50 is vertically symmetrical to the contact portion of the first terminal 16 with the adaptor 50, except for the reduced diameter portion 48.

[0032] The second terminal portion 43 has a configuration in which the small diameter portion 18 of the second inner conductor 44 is coaxially surrounded by the second dielectric 45, and the second inner conductor 44 and the second dielectric 45 are coaxially surrounded by the second outer conductor 46. The second dielectric 45 is located at the lower end of the second outer conductor 46. The space within the second outer conductor 46 above the second dielectric 45 functions as a support space 47 that is open upward. In the support space 47, the large diameter portion 20 of the second inner conductor 44 protrudes upward. Each support space 47 is connected to the second oscillation space 35.

[0033] A continuous reduced diameter portion 48 is formed around the entire circumference of the inner circumference of the upper end of the second outer conductor 46. The reduced diameter portion 48 is disposed in the support space 47, and as shown in FIG. 8, is bent in a V-shape and bulges radially inward in a V-shape. The reduced diameter portion 48 has a receiving portion 78 and a tapered guide portion 79. The receiving portion 78 protrudes from the upper end edge of the second terminal portion 43 all around, obliquely upward toward the inner circumference with respect to the axial direction of the second terminal portion 43. The tapered guide portion 79 protrudes from the protruding end edge of the receiving portion 78 all around, obliquely upward toward the outer circumference with respect to the axial direction of the second terminal portion 43.

[0034] 8, the inclination angle α of the receiving portion 78 with respect to the axial direction of the second terminal portion 43 is larger than the inclination angle β of the tapered guide portion 79 with respect to the axial direction of the second terminal portion 43. The region of the second outer conductor 46 between the second dielectric 45 and the reduced diameter portion 48 is a constant diameter portion 80 that is parallel to the axial direction of the second terminal portion 43 and has a constant inner diameter dimension in the axial direction.

[0035] As shown in Figs. 2 and 9, the adapter 50 has an elongated shape as a whole. The adapter 50 has symmetry such that when both ends in the axial direction are inverted, they have the same shape. As shown in Fig. 9, the adapter 50 is a member including a movable inner conductor 51 made of metal, a movable dielectric 53 made of synthetic resin, and a movable outer conductor 56 made of metal. The adapter 50 is configured such that the movable inner conductor 51 is inserted into an insertion hole 54 of the movable dielectric 53, and the movable outer conductor 56 is fitted to the outer periphery of the movable dielectric 53. The base end 50P and the tip end 50T, which are both ends in the axial direction of the adapter 50, function as a pair of connection ends that can be connected to the first terminal 16 and the second terminal 43. The end faces of the base end 50P and the tip end 50T are exposed. A pair of elastic claw pieces 52 that can be elastically deformed in the radial direction are formed on both ends in the axial direction of the movable inner conductor 51.

[0036] The movable dielectric 53 is made of synthetic resin and has a cylindrical shape coaxial with the axis of the adapter 50. An insertion hole 54 is formed in the center of the movable dielectric 53, coaxially penetrating the movable dielectric 53. Circular accommodating recesses 55 are formed at both axial ends of the movable dielectric 53 by coaxially recessing both end faces of the movable dielectric 53. The accommodating recesses 55 are spaces that constitute both axial ends of the insertion hole 54. The inner diameter of the accommodating recess 55 is larger than the inner diameter of the insertion hole 54. The elastic claw piece 52 of the movable inner conductor 51 is accommodated in the accommodating recess 55.

[0037] A plurality of pairs of locking grooves 81 are formed at equal angular pitches in the circumferential direction on the outer periphery of the movable dielectric 53. The pairs of locking grooves 81 are arranged at positions spaced apart in the axial direction of the movable dielectric 53. A tapered sliding surface 82 is formed in the outer periphery of the movable dielectric 53 in the region on the base end 50P side and the tip end 50T side from the locking groove 81. The tapered sliding surface 82 is gradually reduced in diameter from the axial center of the movable dielectric 53 toward the tip end. The tapered sliding surface 82 on the base end 50P side is inclined so that the facing distance with the inner circumferential surface of the movable outer conductor 56 gradually increases from the axial center toward the base end 50P side. The tapered sliding surface 82 on the tip end 50T side is inclined so that the facing distance with the inner circumferential surface of the movable outer conductor 56 gradually increases from the axial center toward the tip end 50T side.

[0038] The movable outer conductor 56 has a cylindrical shape as a whole. At both axial ends of the movable outer conductor 56, a plurality of pairs of elastic arm portions 57 are formed, which are spaced apart in the circumferential direction. The pairs of elastic arm portions 57 are spaced apart in the axial direction of the adapter 50. The elastic arm portions 57 extend in a cantilevered manner toward the axial end side, and can elastically deform in the radial direction. The elastic arm portions 57 are disposed at a position opposite to the tapered sliding surface 82. The space between the tapered sliding surface 82 and the elastic arm portions 57 functions as a deflection space 59 for elastically displacing the elastic arm portions 57 inward in the radial direction.

[0039] The extended end of the elastic arm 57 is formed with an expanded diameter portion 58. The expanded diameter portion 58 is bent in a V-shape and bulges outward in the radial direction. The expanded diameter portion 58 has a hook portion 83 and a tapered sliding portion 84. The hook portion 83 is in a form that protrudes obliquely toward the outer periphery side with respect to the axial direction of the adapter 50. The tapered sliding portion 84 is in a form that protrudes obliquely from the protruding end edge of the hook portion 83 toward the inner periphery side with respect to the axial direction of the adapter 50. The inclination angle γ of the hook portion 83 with respect to the axial direction of the adapter 50 is smaller than the inclination angle α of the receiving portion 78 with respect to the axial direction of the second terminal portion 43. The inclination angle δ of the tapered sliding portion 84 with respect to the axial direction of the adapter 50 is the same angle as the inclination angle β of the tapered guide portion 79 with respect to the axial line of the second terminal portion 43.

[0040] The movable outer conductor 56 is formed with a plurality of pairs of locking claws 85. The locking claws 85 are formed by partially cutting and raising the movable outer conductor 56, and are elastically deformable in the radial direction. The plurality of pairs of locking claws 85 are arranged at the same pitch as the locking grooves 81 in the circumferential direction. The pair of locking claws 85 are spaced apart in the axial direction of the adapter 50. The locking claws 85 on the base end 50P side protrude obliquely inward toward the tip end 50T side. The locking claws 85 on the tip end 50T side protrude obliquely inward toward the base end 50P side. The locking claws 85 are arranged in a region closer to the center than the elastic arm portion 57 in the axial direction of the adapter 50. When the movable outer conductor 56 and the movable dielectric 53 are assembled, the locking claws 85 are engaged with the locking grooves 81, so that the movable dielectric 53 and the movable outer conductor 56 are held in an assembled state.

[0041] A base end 50P, which is one connection end of the adapter 50, is attached to the second terminal portion 43 in a state where it is inserted into the support space 47 of the second connector 30. In the process of connecting the base end 50P to the second terminal portion 43, the tapered sliding contact portion 84 of the adapter 50 slides against the tapered guide portion 79 of the second terminal portion 43, causing the elastic arm portion 57 to temporarily elastically deform into the deflection space 59. When the enlarged diameter portion 58 passes through the reduced diameter portion 48, the elastic arm portion 57 elastically returns to its original state, and the bent portion of the enlarged diameter portion 58, where the hook portion 83 and the tapered sliding contact portion 84 are connected, elastically contacts the inner circumferential surface of the fixed diameter portion 80 of the second outer conductor 46.

[0042] When the elastic arm portion 57 elastically returns to its original position and the movable outer conductor 56 comes into contact with the second outer conductor 46, the hook portion 83 of the enlarged diameter portion 58 is axially locked to the receiving portion 78 of the reduced diameter portion 48. This locking action prevents the adapter 50 from coming off the second terminal portion 43. Even if the adapter 50 is turned upside down so that it protrudes downward from the second terminal portion 43, the locked state between the enlarged diameter portion 58 and the reduced diameter portion 48 is maintained. The adapter 50 can swing independently, with the contact portion between the base end portion 50P and the second terminal portion 43 as a fulcrum. Even if the adapter 50 swings back and forth or left and right relative to the second terminal portion 43, the locked state between the enlarged diameter portion 58 and the reduced diameter portion 48 is maintained. When the base end 50P is attached to the second terminal portion 43, the large diameter portion 20 of the second inner conductor 44 is accommodated in the accommodating recess 55, and the elastic claw piece 52 of the movable inner conductor 51 elastically contacts the inner circumference of the large diameter portion 20 of the second inner conductor 44.

[0043] The adapter 50 attached to the second terminal portion 43 protrudes upward from the second housing 31. A tip portion 50T of the adapter 50 is adapted to be connected to the first terminal portion 16. Here, since one adapter 50 is supported in a state of contact with only one second terminal portion 43, the multiple adapters 50 can be individually swung in a direction different from the other adapters 50. However, in a state in which the multiple adapters 50 are swung in directions different from each other, when the first connector 10 and the second connector 30 are mated, the tip portions 50T of the multiple adapters 50 cannot be simultaneously connected to the multiple first terminal portions 16.

[0044] As a countermeasure, the second connector 30 is provided with an alignment member 60. The alignment member 60 is a single component made of a metal plate. As shown in FIG. 3, the alignment member 60 has a plate-shaped main body 61 and a pair of elastic holding pieces 68 that are symmetrical on the left and right. The plate-shaped main body 61 is in the shape of a flat plate with its plate thickness direction oriented parallel to the fitting direction of the two connectors 10, 30. The plate-shaped main body 61 has the same shape as the peripheral wall 34 of the second housing 31 in a plan view.

[0045] The plate-shaped main body 61 has a plurality of holes 62 formed in the same arrangement as the plurality of second terminals 43 in a plan view. The holes 62 are circular with an inner diameter dimension larger than the outer diameter of the movable outer conductor 56, and penetrate the plate-shaped main body 61 in the up-down direction. The inner circumference of the holes 62 has a plurality of fixed protrusions 63 formed at intervals in the circumferential direction. The fixed protrusions 63 are formed by closely bending the tip of an extension extending from the inner circumference of the hole 62 toward the center in the radial direction so as to fold it back downward.

[0046] The outer peripheral surface of the protruding end of the fixed protrusion 63 functions as the fixed abutment 64 having a semicircular curved surface. The entire area of ​​the fixed abutment 64 is composed of only non-fractured surfaces that are different from the fractured surfaces generated by the press working on the surface of the alignment member 60. The diameter of the inscribed circle inscribed in the protruding ends of the multiple fixed protrusions 63, i.e., the multiple fixed abutment 64, is the same as or slightly larger than the outer diameter of the movable outer conductor 56. As shown in FIG. 10, a relief recess 86 is formed between the fixed protrusions 63 adjacent to each other in the circumferential direction. The inner diameter of the relief recess 86 is larger than the diameter of a virtual circle (not shown) in contact with the enlarged diameter portion 58 of the elastic arm portion 57.

[0047] A plurality of elastic contact pieces 65 are integrally formed on the plate-shaped main body 61 and arranged so as to overlap the upper surface of the plate-shaped main body 61. The elastic contact pieces 65 are arc-shaped in plan view. Each elastic contact piece 65 extends in a cantilever shape along the opening edge of one hole 62, starting from the outer periphery of the plate-shaped main body 61. A movable protrusion 66 is formed on the extending end of the elastic contact piece 65. The movable protrusion 66 is formed by closely bending the tip of the extending part extending from the inner periphery of the extending end of the elastic contact piece 65 toward the center in the radial direction so as to fold it back upward. The outer periphery of the protruding end of the movable protrusion 66 functions as a movable abutment 67 having a semicircular curved surface. The entire area of ​​the movable abutment 67 is composed of only non-fractured surfaces, similar to the fixed abutment 64.

[0048] As shown in FIG. 3, the elastic holding piece 68 has a pair of front and rear legs 69 extending downward from the side edges of the plate-shaped main body 61 at a right angle to the plate-shaped main body 61, and a locking portion 70 connecting the extending ends of both legs 69. The locking portion 70 is in the form of a plate parallel to the plate-shaped main body 61. As shown in FIGS. 3 and 6, the upper surface of the locking portion 70 is a movable side facing surface 71. The movable side facing surface 71 faces the fixed side facing surface 42 in the up-down direction parallel to the mating direction of the two connectors 10, 30. The elastic holding piece 68 has a guided portion 72 extending obliquely downward from the inner side edge of the locking portion 70.

[0049] The alignment member 60 is attached to the second housing 31 by bringing it close to the second housing 31 from above. During the attachment process, the pair of guided portions 72 slide against the pair of guide inclined surfaces 41, causing the pair of elastic holding pieces 68 to elastically deform in a direction approaching each other. When the guided portions 72 and the locking portions 70 pass the holding projections 40, the pair of elastic holding pieces 68 elastically return to their original state and are housed within the holding space 39. The movable side opposing surface 71 of the elastic holding piece 68 faces the fixed side opposing surface 42 of the second housing 31 from below. This completes the assembly of the alignment member 60 to the second housing 31.

[0050] When the alignment member 60 is attached to the second housing 31, the outer peripheral edge of the plate-shaped main body 61 rests on the upper end surface of the peripheral wall 34, the legs 69 and the locking portions 70 are housed in the retaining spaces 39, and the locking portions 70 slip under the retaining projections 40. The locking portions 70 lock onto the retaining projections 40, thereby preventing the alignment member 60 from coming off the second housing 31. When the outer peripheral edge of the plate-shaped main body 61 is aligned with the peripheral wall 34, clearances are ensured between the legs 69 and the support wall 38 and between the locking portions 70 and the support wall 38.

[0051] Therefore, the alignment member 60 is held in a state in which relative displacement in a direction parallel to the plate-shaped main body 61 is permitted with respect to the second housing 31. The direction parallel to the plate-shaped main body 61 is a direction that intersects at right angles with the mating direction of the two connectors 10, 30, and is a direction in which the positional deviation of the two circuit boards B, C is expected. The relative displacement of the alignment member 60 with respect to the second housing 31 is maximum when the leg 69 or the locking portion 70 abuts against the support wall 38. In the state in which the relative displacement of the alignment member 60 is maximum, at least a part of the movable side opposing surface 71 maintains a state in which it faces at least a part of the fixed side opposing surface 42 in the vertical direction. Therefore, even if the displacement of the alignment member 60 is maximum, the alignment member 60 is held in a state attached to the second housing 31.

[0052] After the alignment member 60 is attached to the second housing 31, the multiple adapters 50 are attached to the second terminal portion 43. When attaching the adapter 50, the base end 50P of the adapter 50 is inserted through the hole 62 and advanced into the second swing space 35, and fitted into the support space 47 of the second terminal portion 43. The alignment member 60 may be attached to the second housing 31 after the adapter 50 is attached to the second terminal portion 43. As shown in FIG. 10, when the tip portion 50T of the adapter 50 passes through the hole 62, the enlarged diameter portion 58 of the elastic arm portion 57 passes through the relief recess 86, so there is no risk of the enlarged diameter portion 58 interfering with the alignment member 60.

[0053] With the adapter 50 and alignment member 60 attached to the second housing 31, the entire outer periphery of the movable outer conductor 56 is surrounded by the hole edge of the hole 62. Since the fixed abutment portion 64 and the movable abutment portion 67 abut against the outer periphery of the movable outer conductor 56, the adapter 50 is held in a state in which relative displacement in a direction parallel to the plate-shaped main body portion 61 is restricted with respect to the alignment member 60. Since the alignment member 60 is conductive, when the fixed abutment portion 64 and the movable abutment portion 67 abut against the outer periphery of the movable outer conductor 56, the alignment member 60 and the multiple adapters 50 are electrically connected to each other so as to be conductive.

[0054] The portion where the alignment member 60 comes into contact with the movable outer conductor 56 is a region between the elastic arm portion 57 on the base end portion 50P side and the elastic arm portion 57 on the tip end portion 50T side in the axial direction of the adapter 50. Therefore, neither the fixed contact portion 64 nor the movable contact portion 67 comes into contact with the elastic arm portion 57. This prevents damage and deformation of the elastic arm portion 57.

[0055] The relative displacement of each adapter 50 with respect to the alignment member 60 is restricted, and the relative displacement between the adapters 50 is restricted by the alignment member 60. When an external force in the swing direction acts on any one of the adapters 50, all the adapters 50 swing in the same direction and by the same angle together with the alignment member 60. Therefore, the positional relationship of the tip ends 50T of all the adapters 50 is kept constant regardless of the swing direction and swing angle of the adapters 50. The kept positional relationship is the same as that of the plurality of first terminals 16. The adapter 50 swings around the connection part between the second terminal 43 and the base end 50P of the adapter 50 as a fulcrum. The swing angle of the adapter 50 is maximum when the adapter 50 abuts against the peripheral wall 34. In other words, when the adapter 50 abuts against the peripheral wall 34, the inclination of the adapter 50 is restricted.

[0056] The amount of displacement of the alignment member 60 when the adapter 50 is tilted increases as the contact position of the alignment member 60 approaches the tip 50T of the adapter 50. When the adapter 50, which is in sliding contact with the guide portion 14, presses the alignment member 60 in the horizontal direction, the pressing force generated between the adapter 50 and the alignment member 60 increases as the contact position of the alignment member 60 approaches the base end 50P of the adapter 50. In this embodiment, since the contact position of the alignment member 60 is an intermediate position between the base end 50P and the tip 50T, it is possible to reduce the pressing force generated between the adapter 50 and the alignment member 60 while suppressing the amount of displacement of the alignment member 60 when the adapter 50 is tilted.

[0057] When the first connector 10 and the second connector 30 are mated, if the first circuit board B and the second circuit board C are displaced relative to each other, the tip 50T of one of the adapters 50 comes into contact with the inner surface of the guide portion 14. When the two connectors 10 and 30 are mated further from this state, the tip 50T of the adapter 50 comes into sliding contact with the inclined inner surface of the guide portion 14, so that the tip portions 50T of all the adapters 50 are guided to the connection position with the first terminal portion 16 while changing the swing angle all at once. During this time, the base end 50P of the adapter 50 swings within the second swing space 35, and the tip portions 50T of the adapters 50 swing within the first swing space 15.

[0058] The tip end of the tip portion 50T protrudes toward the first terminal portion 16 beyond the protruding end of the hook portion 83, which is the contact point with the guiding portion 14, of the expanded diameter portion 58. Therefore, in the process in which the guiding portion 14 guides the tip portion 50T, a part of the tip portion 50T advances upward (toward the first terminal holding portion 12) beyond the base end 14P of the guiding portion 14 before the expanded diameter portion 58 reaches the base end 14P of the guiding portion 14. In particular, when the first connector 10 and the second connector 30 are misaligned on a horizontal plane perpendicular to the opposing direction of both connectors 10, 30, the tip surface of the tip portion 50T becomes inclined with respect to the front surface 12S of the first terminal holding portion 12 of the first connector 10, and the amount of advancement of the tip portion 50T increases.

[0059] However, since the front surface 12S of the first terminal holding portion 12 is located above the base end 14P of the guiding portion 14, the tip portion 50T does not interfere with the front surface 12S of the first terminal holding portion 12. Therefore, the expanded diameter portion 58 can reach the base end 14P of the guiding portion 14 without the tip portion 50T interfering with the front surface 12S of the first terminal holding portion 12. When the expanded diameter portion 58 reaches the base end 14P of the guiding portion 14, the center of the tip portion 50T approaches the axis of the first terminal portion 16 in a plan view.

[0060] Thereafter, as the connection between the tip portion 50T and the first terminal portion 16 progresses, the enlarged diameter portion 58 slides against the guide surface 76, so that the center of the tip portion 50T is arranged coaxially with the first terminal portion 16. As the connection between the tip portion 50T and the first terminal portion 16 progresses, the enlarged diameter portion 58 elastically contacts the inner peripheral surface of the first outer conductor 22, and the movable inner conductor 51 elastically contacts the first inner conductor 17. When the tip portion 50T of the adapter 50 is connected to the first terminal portion 16 as described above, the first connector 10 and the second connector 30 are properly fitted together. When the two connectors 10 and 30 are properly fitted together, the first circuit board B and the second circuit board C are connected together via the first terminal portion 16, the alignment member 60, and the second terminal portion 43.

[0061] The movable inner conductor 51 is inserted with a clearance in the insertion hole 54 of the movable dielectric 53. Therefore, the movable inner conductor 51 can be displaced relatively with its axis tilted with respect to the movable dielectric 53 and the movable outer conductor 56. As a result, even when the adapter 50 swings and the axis of the adapter 50 tilts with respect to the axes of the first terminal portion 16 and the second terminal portion 43, it is possible to achieve both a good contact state of the movable inner conductor 51 with the first inner conductor 17 and the second inner conductor 44 and a good contact state of the movable outer conductor 56 with the first outer conductor 22 and the second outer conductor 46, regardless of the swing angle.

[0062] The connector device A of the first embodiment includes a first connector 10, a second connector 30, and an adapter 50. The first connector 10 has a first terminal portion 16, and is mounted on a first circuit board B. The second connector 30 has a second terminal portion 43, and is mounted on a second circuit board C. The adapter 50 has a base end portion 50P and a tip end portion 50T that function as a pair of connecting ends.

[0063] The first terminal portion 16 and the second terminal portion 43 have a first inner conductor 17 and a second inner conductor 44 as contact portions that are symmetrical to each other, and have a first outer conductor 22 and a second outer conductor 46 as contact portions that are symmetrical to each other. A base end portion 50P and a tip end portion 50T of the adapter 50 are capable of contacting the first inner conductor 17, the first outer conductor 22, the second inner conductor 44, and the second outer conductor 46. The base end portion 50P and the tip end portion 50T are symmetrical with respect to the direction in which the first terminal portion 16 and the second terminal portion 43 face each other.

[0064] According to this configuration, the base end 50P and the tip end 50T of the adapter 50 are symmetrical, so there is no need to check the orientation of the adapter 50 when connecting the adapter 50 to the first terminal 16 or the second terminal 43. Therefore, the connector device A of this embodiment is excellent in workability during assembly.

[0065] The adapter 50 has a movable inner conductor 51, a movable dielectric 53 that houses the movable inner conductor 51, and a movable outer conductor 56 that surrounds the movable dielectric 53. The movable dielectric 53 is exposed at an end face of the base end 50P and an end face of the tip end 50T. With this configuration, when connecting the base end 50P and the tip end 50T to the first terminal 16 or the second terminal 43, the movable dielectric 53 can be pressed and operated, which improves workability.

[0066] At least a pair of locking grooves 81 spaced apart in the axial direction are formed on the outer periphery of the movable dielectric 53. At least a pair of locking claws 85 spaced apart in the axial direction are formed on the movable outer conductor 53. The locking claws 85 obliquely protrude toward the inner periphery and are elastically deformable in the radial direction. In the process of assembling the movable outer conductor 56 to the movable dielectric 53, the locking claws 85 slide against the outer periphery of the movable dielectric 53 in an elastically deformed state. When the movable outer conductor 56 is properly assembled to the movable dielectric 53, the elastically restored locking claws 85 are locked in the locking grooves 81, thereby restricting the relative displacement of the movable dielectric 53 and the movable outer conductor 56 in the axial direction. This allows the movable dielectric 53 and the movable outer conductor 56 to be held in an assembled state.

[0067] The pair of locking claws 85 are formed at two locations spaced apart in the axial direction, and the pair of locking claws 85 protrude in an oblique direction toward the other locking claw 85. According to this configuration, in the process of assembling the movable outer conductor 56 to the movable dielectric 53, the locking claw 85 at the front in the assembling direction passes through the locking groove 81 at the front side in the assembling direction. When the movable outer conductor 56 is properly assembled to the movable dielectric 53, the pair of locking claws 85 elastically return to their original position and are individually locked in the pair of locking grooves 81. Since the pair of locking claws 85 lock the movable dielectric 53 in opposite directions, the relative displacement of the movable outer conductor 56 and the movable dielectric 53 in two directions, forward and reverse, along the axis is restricted.

[0068] The outer peripheral surface of the movable dielectric 53 is formed with a tapered sliding surface 82 that is inclined so that the distance between the inner peripheral surface of the movable outer conductor 56 and the base end 50P side and the tip end 50T side gradually increases. According to this configuration, in the process of assembling the movable outer conductor 56 to the movable dielectric 53, the locking claw 85 slides against the tapered sliding surface 82, so there is no risk of the protruding end of the locking claw 85 getting caught on the outer peripheral surface of the movable dielectric 53. The locking claw 85 is formed in a region different from the elastic arm portion 57 in the axial direction of the adapter 50. According to this configuration, the rigidity of the elastic arm portion 57 is not reduced by forming the locking claw 85, so that the connection reliability of the elastic arm portion 57 to the first terminal portion 16 and the second terminal portion 43 is high.

[0069] The movable outer conductor 56 has a resilient arm portion 57 which is connected to the first terminal portion 16 or the second terminal portion 43 in a state where it is resiliently displaced toward the inner periphery. The resilient arm portion 57 is disposed in a region facing the tapered sliding contact surface 82. According to this configuration, the space between the tapered sliding contact surface 82 and the resilient arm portion 57 functions as a deflection space 59 for allowing the resilient displacement of the resilient arm portion 57, so that the outer diameter dimension of the movable outer conductor 56 can be kept small.

[0070] The adapter 50 has a hook portion 83 formed at the base end 50P and the tip end 50T, which protrudes radially from the movable outer conductor 56. The second terminal portion 43 has a receiving portion 78 formed thereon, which holds the adapter 50 on the second connector 30 by engaging the hook portion 83. With this configuration, the adapter 50 can be held in a suspended state relative to the second connector 30 by engaging the hook portion 83 with the receiving portion 78. Therefore, it is not necessary to support the adapter 50 by hand until the adapter 50 and the first connector 10 are connected. This improves workability.

[0071] The reduced diameter portion 48 of the second terminal portion 43 has a tapered guide portion 79 that guides the base end portion 50P to an engaged state with the receiving portion 78. The inclination angle α of the receiving portion 78 with respect to the connecting direction of the second terminal portion 43 and the base end portion 50P is larger than the inclination angle β of the tapered guide portion 79 with respect to the connecting direction of the connecting end portion of the second terminal portion 43 and the base end portion 50P. With this configuration, it is possible to improve the engaging function between the hook portion 83 and the receiving portion 78 while reducing the resistance when guiding the base end portion 50P to the engaged state with the receiving portion 78.

[0072] The movable outer conductor 56 of the base end 50P is formed with a tapered sliding portion 84 that slides against the tapered guide portion 79 in the process of locking the hook portion 83 into the receiving portion 78. The inclination angle δ of the tapered sliding portion 84 with respect to the connection direction between the second terminal portion 43 and the base end 50P is the same as the inclination angle β of the tapered guide portion 79 with respect to the connection direction between the second terminal portion 43 and the base end 50P. According to this configuration, the tapered sliding portion 84 is guided while being in surface contact with the tapered guide portion 79, so there is no risk of the tapered sliding portion 84 getting caught between the tapered guide portion 79 and the tapered guide portion 79, and the guide function has excellent reliability.

[0073] The receiving portion 78 protrudes radially inward from the inner periphery of the second terminal portion 43. The base end portion 50P has a resilient arm portion 57. The hook portion 83 protrudes radially outward from the resilient arm portion 57. The protruding end of the hook portion 83 is in elastic contact with the inner periphery of the second terminal portion 43. With this configuration, the protruding dimension of the receiving portion 78 from the inner periphery of the second terminal portion 43 is reliably secured as a radial engagement allowance between the receiving portion 78 and the hook portion 83, resulting in excellent contact reliability.

[0074] The hook portions 83 are arranged at a plurality of positions spaced apart in the circumferential direction. A constant diameter portion 80 having a constant inner diameter is formed in an area of ​​the inner circumference of the second terminal portion 43 with which the hook portions 83 can come into contact, and the constant diameter portion 80 is continuous in the direction of connection between the second terminal portion 43 and the base end portion 50P. With this configuration, even if the adapter 50 is tilted with respect to the second connector 30, the plurality of hook portions 83 can reliably come into contact with the constant diameter portion 80 on the inner circumference of the second terminal portion 43.

[0075] The adapter 50 has a movable dielectric 53 and a movable outer conductor 56 surrounding the movable dielectric 53. The movable outer conductor 56 is formed with an elastic arm portion 57 and a locking claw 85. The locking claw 85 is formed in an area of ​​the movable outer conductor 56 other than the elastic arm portion 57, and holds the movable dielectric 53 and the movable outer conductor 56 in an assembled state by being locked in the locking groove 81. With this configuration, the formation of the locking claw 85 does not reduce the rigidity of the elastic arm portion 57, so that the contact reliability between the second terminal portion 43 and the hook portion 83 is high.

[0076] The second connector 30 has a peripheral wall portion 34 that surrounds the adapter 50 with the base end portion 50P connected to the second terminal portion 43. The inclination of the adapter 50 is restricted by contacting the peripheral wall portion 34. According to this configuration, the inclination of the adapter 50 is restricted by the peripheral wall portion 34, so that the hook portion 83 can reliably contact the inner periphery of the second terminal portion 43.

[0077] The first connector 10 has a first terminal portion 16 and is mounted on the first circuit board B. The second connector 30 has a second terminal portion 43 and is mounted on the second circuit board C with the second terminal portion 43 facing the first terminal portion 16. The adapter 50 as a movable terminal portion can swing around the second terminal portion 43 as a fulcrum and has a tip portion 50T as a connection end portion connected to the first terminal portion 16. The first connector 10 has a first terminal holding portion 12 that houses the first terminal portion 16 and a guiding portion 14. The guiding portion 14 is disposed closer to the second connector 30 than the front surface 12S of the first terminal holding portion 12 and extends in a tapered shape from the base end 14P toward the tip end 14T. An interference avoidance portion 75 is interposed between the outer peripheral edge of the front surface 12S of the first terminal holding portion 12 and the base end 14P of the guiding portion 14.

[0078] According to this configuration, in the process of connecting the first connector 10 and the second connector 30, the tip 50T of the adapter 50 is guided by sliding against the guide portion 14 and connected to the first terminal portion 16. If the first connector 10 and the second connector 30 are misaligned in a direction intersecting the opposing direction of the first terminal portion 16 and the second terminal portion 43, the tip 50T reaches the base end 14P of the guide portion 14 while the attitude of the adapter 50 remains tilted with respect to the opposing direction of the two connectors 10 and 30, and the guiding by the guide portion 14 ends. At this time, the tip surface of the tip 50T is inclined with respect to the front surface 12S of the first terminal holding portion 12, so that the tip 50T protrudes toward the front surface 12S of the first terminal holding portion 12 just before reaching the base end 14P of the guide portion 14.

[0079] Here, a space for accommodating the tip portion 50T is secured by the interference avoidance portion 75 between the base end 14P of the guiding portion 14 and the front surface 12S of the first terminal holding portion 12. Therefore, the tip portion 50T reaches the base end 14P of the guiding portion 14 without interfering with the front surface 12S of the first terminal holding portion 12, is guided so as to face the first terminal portion 16, and is connected to the first terminal portion 16. Therefore, the connector device A of this embodiment has high reliability of the connection operation.

[0080] The first terminal holding portion 12 has a first terminal accommodating chamber 13 that opens to a front surface 12S of the first terminal holding portion 12 and accommodates the first terminal portion 16. A tapered guide surface 76 that guides the tip portion 50T into the first terminal accommodating chamber 13 is formed on the opening edge of the first terminal accommodating chamber 13. With this configuration, the tip portion 50T can be reliably guided into the first terminal accommodating chamber 13.

[0081] The first terminal portion 16 has a first inner conductor 17 and a first outer conductor 22 surrounding the first inner conductor 17. The tip portion 50T has a movable inner conductor 51 connected to the first inner conductor 17, a movable dielectric 53 surrounding the movable inner conductor 51, and a movable outer conductor 56 surrounding the movable dielectric 53 and connected to the inner circumference of the first outer conductor 22. The tip surface of the movable dielectric 53 is exposed at the tip surface of the tip portion 50T. The first inner conductor 17 is disposed only in a region behind the inner end 76E of the guiding surface 76.

[0082] According to this configuration, in the process of connecting the tip portion 50T to the first terminal 16, the connection between the movable outer conductor 56 and the first outer conductor 22 starts, so that the tip portion 50T is positioned with respect to the first terminal 16, but at this point, the first inner conductor 17 is not in contact with the tip of the tip portion 50T. Therefore, there is no risk of the movable dielectric 53 interfering with the first terminal 16 in the process of connecting the tip portion 50T to the first terminal 16.

[0083] The cross-sectional shape of the guide surface 76 when cut perpendicularly to the opposing direction of the first terminal portion 16 and the second terminal portion 43 is circular. The radius of curvature of the guide surface 76 on the front surface 12S of the first terminal holding portion 12 is larger than ½ the pitch between adjacent first terminal accommodating chambers 13. With this configuration, the partition wall portion 77 separating adjacent first terminal accommodating chambers 13 is recessed in an arc shape from the front surface 12S of the first terminal holding portion 12. This makes it difficult for the tip portion 50T to interfere with the front surface 12S of the first terminal holding portion 12.
