[Explanation of Embodiments of the present disclosure]
First, the embodiments of the present disclosure will be listed and described.
The connector device of the present disclosure is
(1) A first connector having a first terminal portion and mounted on a first circuit board, and a second terminal portion having the second terminal portion facing the first terminal portion. The first connector is provided with a second connector mounted on a two-circuit board and a movable terminal portion that is swingable with the second terminal portion as a fulcrum and has a connection end portion connected to the first terminal portion. The connector includes a terminal holding portion accommodating the first terminal portion and an induction portion arranged on the second connector side of the front surface of the terminal holding portion and extending in a tapered shape from the base end toward the tip end. An interference avoidance portion is interposed between the outer peripheral edge of the front surface of the terminal holding portion and the base end of the guiding portion.

According to this configuration, in the process of connecting the first connector and the second connector, the connection end portion of the movable terminal portion is guided by sliding contact with the guide portion and is connected to the first terminal portion. When the first connector and the second connector are misaligned in the direction of intersection with respect to the opposite direction of the first terminal portion and the second terminal portion, the posture of the movable terminal portion is tilted with respect to the opposite direction of both connectors. In this state, the connection end reaches the base end of the guide portion, and the guide by the guide portion ends. At this time, since the tip surface of the connection end portion is inclined with respect to the front surface of the terminal holding portion, the connection end portion projects toward the front side of the terminal holding portion immediately before reaching the base end of the guide portion. Here, since a space for accommodating the connection terminal portion is secured between the base end of the guide portion and the front surface of the terminal holding portion by the interference avoiding portion, the connection end portion interferes with the front surface of the terminal holding portion. It reaches the base end of the induction portion without any trouble, is guided so as to face the first terminal portion, and is connected to the first terminal portion. The connector device of the present disclosure has high reliability of connection operation.

(2) The terminal holding portion is formed with a first terminal accommodating chamber that opens in front of the terminal holding portion and accommodates the first terminal portion, and the opening edge portion of the first terminal accommodating chamber is formed. It is preferable that a tapered guide surface is formed to guide the connection end portion into the first terminal accommodating chamber. According to this configuration, the connection end can be reliably invited into the first terminal accommodating chamber.

(3) In (2), the first terminal portion has a first inner conductor and a first outer conductor surrounding the first inner conductor, and the connection end portion is formed on the first inner conductor. It has a movable inner conductor to be connected, a movable dielectric that surrounds the movable inner conductor, and a movable outer conductor that surrounds the movable dielectric and is connected to the inner circumference of the first outer conductor. It is preferable that the tip surface of the dielectric is exposed on the tip surface of the connection end portion, and the first inner conductor is arranged only in a region deeper than the back end of the guide surface. According to this configuration, in the process of connecting the connection end portion to the first terminal portion, the connection end portion is positioned with respect to the first terminal portion by starting the connection between the movable outer conductor and the first outer conductor. However, at this point, the first inner conductor is in non-contact with the tip of the connecting end. Therefore, there is no possibility that the movable dielectric will interfere with the first terminal portion in the process of advancing the connection between the connection end portion and the first terminal portion.

(4) In (2) or (3), the cross-sectional shape of the guide surface when cut at right angles to the opposite direction of the first terminal portion and the second terminal portion is circular, and the terminal holding portion is said to have a circular shape. The radius of curvature of the guide surface on the front surface is preferably larger than 1/2 of the pitch between the adjacent first terminal accommodating chambers. According to this configuration, the partition wall portion that partitions the adjacent first terminal accommodating chambers is formed to be recessed in an arc shape with respect to the front surface of the terminal holding portion. This makes it difficult for the connection end to interfere with the front of the terminal holding portion.

The hole 62 has a circular shape having an inner diameter larger than the outer diameter of the movable outer conductor 56. It is a form that penetrates the plate-shaped main body 61 in the vertical direction. A plurality of fixed protrusions 63 spaced apart from each other in the circumferential direction are formed on the inner circumference of the hole 62. The fixed protrusion 63 is formed by closely bending the tip of the extension extending from the inner circumference of the hole 62 toward the center in the radial direction so as to fold back downward.

The outer peripheral surface of the protruding end of the fixed protrusion 63 functions as a fixed contact portion 64 having a semicircular curved surface. The entire region of the fixed contact portion 64 is composed of only a non-fracture section different from the fracture surface generated by press working on the surface of the alignment member 60. The protruding end of the plurality of fixed protrusions 63, that is, the diameter of the inscribed circle inscribed in the plurality of fixed contact portions 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 the virtual circle (not shown) in contact with the enlarged diameter portion 58 of the elastic arm portion 57.

A plurality of elastic contact pieces 65 arranged so as to overlap the upper surface of the plate-shaped main body 61 are integrally formed on the plate-shaped main body 61. The plan view shape of the elastic contact piece 65 is an arc shape. One elastic contact piece 65 has a form extending in a cantilever shape along the opening edge of one hole 62 with the outer peripheral edge of the plate-shaped main body 61 as a base point. A movable protrusion 66 is formed at the extending end of the elastic contact piece 65. The movable protrusion 66 is formed by closely bending the tip of the extension portion extending from the inner circumference of the extension end portion of the elastic contact piece 65 toward the center in the radial direction so as to fold back upward. The outer peripheral surface of the protruding end of the movable protrusion 66 functions as a movable contact portion 67 having a semicircular curved surface shape. Like the fixed contact portion 64, the entire region of the movable contact portion 67 is composed of only a non-broken cross section.

As shown in FIG. 3, the elastic holding piece 68 includes a pair of front and rear leg portions 69 extending downward at right angles to the plate-shaped main body portion 61 from the side edge of the plate-shaped main body portion 61, and extending ends of both leg portions 69. It has a locking portion 70 that connects the two. The locking portion 70 has a plate shape parallel to the plate-shaped main body portion 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 vertical direction parallel to the fitting direction of both connectors 10 and 30. The elastic holding piece 68 is formed with a guided portion 72 that projects diagonally downward from the inner side edge of the locking portion 70.

The alignment member 60 is attached to the second housing 31 by approaching the second housing 31 from above. In the process of attachment, the pair of guided portions 72 are in sliding contact with the pair of guide slopes 41, so that the pair of elastic holding pieces 68 are elastically deformed in the direction of approaching each other. When the guided portion 72 and the locking portion 70 pass through the holding projection 40, the pair of elastic holding pieces 68 are elastically restored and accommodated in the holding space 39. The movable side facing surface 71 of the elastic holding piece 68 faces the fixed side facing surface 42 of the second housing 31 from below. As described above, the assembly of the alignment member 60 with respect to the second housing 31 is completed.

In a state where the alignment member 60 is attached to the second housing 31, the outer peripheral edge portion of the plate-shaped main body portion 61 is placed on the upper end surface of the peripheral wall portion 34, and the leg portion 69 and the locking portion 70 are housed in the holding space 39. Then, the locking portion 70 slips under the holding protrusion 40. By locking the locking portion 70 to the holding projection 40, the alignment member 60 is restricted from being detached from the second housing 31. In a state where the outer peripheral edge of the plate-shaped main body portion 61 is aligned with the peripheral wall portion 34, a clearance is secured between the leg portion 69 and the support wall portion 38 and between the locking portion 70 and the support wall portion 38.

Therefore, the alignment member 60 is held in a state in which the relative displacement in the direction parallel to the plate-shaped main body 61 is allowed with respect to the second housing 31. The direction parallel to the plate-shaped main body 61 is a direction that intersects the fitting directions of both connectors 10 and 30 at right angles, and is a direction in which misalignment of both circuit boards B and C is assumed. The amount of relative displacement of the alignment member 60 with respect to the second housing 31 is maximum when the leg portion 69 or the locking portion 70 comes into contact with the support wall portion 38. In the state where the relative displacement amount of the alignment member 60 is maximized, at least a part of the movable side facing surface 71 is kept in a state of vertically facing at least a part of the fixed side facing surface 42. Therefore, even if the displacement amount of the alignment member 60 is maximum, the alignment member 60 is held in a state of being attached to the second housing 31.

After attaching the alignment member 60 to the second housing 31, a plurality of adapters 50 are attached to the second terminal portion 43. When attaching the adapter 50, the base end portion 50P of the adapter 50 is inserted into the hole portion 62 and entered into the second swinging space 35, and is 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 portion 62, the diameter-expanded portion 58 of the elastic arm portion 57 passes through the relief recess 86, so that the diameter-expanded portion 58 interferes with the alignment member 60. There is no risk of doing so.

In a state where the adapter 50 and the alignment member 60 are attached to the second housing 31, the outer circumference of the movable outer conductor 56 is surrounded by the hole edge portion of the hole portion 62 over the entire circumference. Since the fixed contact portion 64 and the movable contact portion 67 abut on the outer circumference of the movable outer conductor 56, the adapter 50 is restricted from being displaced relative to the alignment member 60 in the direction parallel to the plate-shaped main body portion 61. It is held in a state of being. Since the alignment member 60 has conductivity, when the fixed contact portion 64 and the movable contact portion 67 come into contact with the outer periphery of the movable outer conductor 56, the alignment member 60 and the plurality of adapters 50 are electrically connected to each other.

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. As a result, damage or deformation of the elastic arm portion 57 is prevented.

By regulating the relative displacement of each adapter 50 with respect to the alignment member 60, the relative displacement between the adapters 50 is regulated 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 are integrally with the alignment member 60 and swing in the same direction and at the same angle. Therefore, the positional relationship of the tip portions 50T of all the adapters 50 is maintained at a constant positional relationship regardless of the swing direction and swing angle of the adapter 50. The maintained positional relationship is the same as that of the plurality of first terminal portions 16. The adapter 50 swings around the connection portion between the second terminal portion 43 and the base end portion 50P of the adapter 50 as a fulcrum. The swing angle of the adapter 50 becomes maximum when the adapter 50 comes into contact with the peripheral wall portion 34. That is, when the adapter 50 comes into contact with the peripheral wall portion 34, the inclination of the adapter 50 is limited.

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 portion 50T of the adapter 50. When the adapter 50 that is in sliding contact with the guide portion 14 pushes the alignment member 60 in the horizontal direction, the pressing force generated between the adapter 50 and the alignment member 60 is such that the contact position of the alignment member 60 is the base end portion of the adapter 50. The closer it is to 50P, the larger it becomes. In this embodiment, since the contact position of the alignment member 60 is an intermediate position between the base end portion 50P and the tip end portion 50T, the adapter 50 and the alignment member 60 can be combined while suppressing the displacement amount of the alignment member 60 when the adapter 50 is tilted. It is possible to reduce the pressing force generated between the two.

If the first circuit board B and the second circuit board C are relatively displaced when the first connector 10 and the second connector 30 are fitted, the tip portion 50T of any of the adapters 50 is the guide portion 14. Contact the inner surface of. When the mating of both connectors 10 and 30 is further advanced from this state, the tip 50T of the adapter 50 slides into contact with the inclined inner surface of the guide portion 14, and the tip 50T of all the adapters 50 shakes all at once. While changing the moving angle, it is guided to the connection position with the first terminal portion 16. During this time, the base end portion 50P of the adapter 50 swings in the second swing space 35, and the tip end portion 50T of the adapter 50 swings in the first swing space 15.

The tip of the tip portion 50T protrudes from the protruding end of the hook portion 83, which is the contact point with the guide portion 14, of the diameter-expanded portion 58, to the first terminal portion 16. Therefore, in the process in which the guiding portion 14 guides the tip portion 50T, a part of the tip portion 50T reaches the base end 14P of the guiding portion 14 before the diameter-expanded portion 58 reaches the base end 14P of the guiding portion 14. It advances to the upper side (the first terminal holding part 12 side). In particular, when the first connector 10 and the second connector 30 are misaligned on a horizontal plane perpendicular to the opposite direction of both connectors 10 and 30, the tip surface of the tip portion 50T is the first terminal of the first connector 10. Since it is slanted with respect to the front surface 12S of the holding portion 12, the amount of advancement of the tip portion 50T becomes large.

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 diameter-expanded portion 58 can reach the base end 14P of the induction portion 14 without the tip portion 50T interfering with the front surface 12S of the first terminal holding portion 12. When the enlarged diameter portion 58 reaches the base end 14P of the guide portion 14, the center of the tip portion 50T approaches the axis of the first terminal portion 16 in a plan view.

After that, when the connection between the tip portion 50T and the first terminal portion 16 progresses, the diameter-expanded portion 58 slides into contact with the guide surface 76, so that the center of the tip portion 50T is arranged coaxially with the first terminal portion 16. To. Further, 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 becomes the first inner conductor 51. Elastically contacts the 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 in a normal mating state. When both connectors 10 and 30 are normally fitted, the first circuit board B and the second circuit board C are connected via the first terminal portion 16, the alignment member 60, and the second terminal portion 43.

The movable inner conductor 51 is inserted through the insertion hole 54 of the movable dielectric 53 with a clearance. Therefore, the movable inner conductor 51 can be relatively displaced with respect to the movable dielectric 53 and the movable outer conductor 56 in such a manner that the axes are tilted. As a result, even when the adapter 50 swings and the axis of the adapter 50 is tilted with respect to the axes of the first terminal portion 16 and the second terminal portion 43, the first inner conductor 17 and the first inner conductor 17 and the second are regardless of the swing angle. 2 It is possible to achieve both a good contact state of the movable inner conductor 51 with respect to the inner conductor 44 and a good contact state of the movable outer conductor 56 with respect to the first outer conductor 22 and the second outer conductor 46.

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 the first circuit board B. The second connector 30 has a second terminal portion 43 and is mounted on the 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 connection ends.

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 having a symmetrical shape with each other, and the first outer conductor 22 as a contact portion symmetrical with each other. And a second outer conductor 46. The base end portion 50P and the tip end portion 50T of the adapter 50 can come into contact with 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 have a shape symmetrical with respect to the direction in which the first terminal portion 16 and the second terminal portion 43 face each other.

According to this configuration, the base end portion 50P and the tip end portion 50T provided on the adapter 50 have a symmetrical shape, so that when the adapter 50 is connected to the first terminal portion 16 or the second terminal portion 43, the orientation of the adapter 50 is changed. No need to check. Therefore, the connector device A of this embodiment is excellent in workability at the time of assembly.

The adapter 50 has a movable inner conductor 51, a movable dielectric 53 accommodating the movable inner conductor 51, and a movable outer conductor 56 surrounding the movable dielectric 53. The movable dielectric 53 is exposed on the end face of the base end portion 50P and the end face of the tip end portion 50T. According to this configuration, when the base end portion 50P and the tip end portion 50T are connected to the first terminal portion 16 or the second terminal portion 43, the movable dielectric 53 can be pushed and operated, so that workability is good.

At least a pair of locking grooves 81 are formed on the outer periphery of the movable dielectric 53 at intervals in the axial direction. The movable outer conductor 53 is formed with at least a pair of locking claws 85 spaced apart from each other in the axial direction. The locking claw 85 projects obliquely toward the inner peripheral side and is elastically deformable in the radial direction. In the process of assembling the movable outer conductor 56 to the movable dielectric 53, the locking claw 85 is in sliding contact with the outer peripheral surface of the movable dielectric 53 in a state of being elastically deformed. When the movable outer conductor 56 is properly assembled to the movable dielectric 53, the elastically restored locking claw 85 is locked in the locking groove 81 in the axial direction between the movable dielectric 53 and the movable outer conductor 56. Relative displacement of is regulated. As a result, the movable dielectric 53 and the movable outer conductor 56 are held in the assembled state.

The paired locking claws 85 are formed at two positions spaced apart from each other in the axial direction, and the paired locking claws 85 project diagonally toward the locking claws 85 on the opposite side of each other. .. According to this configuration, in the process of assembling the movable outer conductor 56 to the movable dielectric 53, the locking claw 85 in front of the assembling direction passes through the locking groove 81 on the front side in the assembling direction. When the movable outer conductor 56 is properly assembled to the movable dielectric 53, the paired locking claws 85 elastically return and individually lock into the paired locking grooves 81. Since the pair of locking claws 85 are locked to the movable dielectric 53 in opposite directions, the movable outer conductor 56 and the movable dielectric 53 are restricted from being displaced relative to each other in two forward and reverse directions along the axis. To.

On the outer peripheral surface of the movable dielectric 53, a tapered sliding contact surface 82 is provided, which is inclined so that the distance between the movable outer conductor 56 and the inner peripheral surface gradually increases toward the base end portion 50P side and the tip end portion 50T side. It is formed. According to this configuration, in the process of assembling the movable outer conductor 56 to the movable dielectric 53, the locking claw 85 is in sliding contact with the tapered sliding contact surface 82, so that the protruding end of the locking claw 85 is the outer periphery of the movable dielectric 53. There is no risk of getting caught on the surface. 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 does not decrease due to the formation of the locking claw 85, so that the connection reliability of the elastic arm portion 57 with respect to the first terminal portion 16 and the second terminal portion 43 is improved. high.

The movable outer conductor 56 has an elastic arm portion 57 connected to the first terminal portion 16 or the second terminal portion 43 in a state of being elastically displaced toward the inner peripheral side. The elastic arm portion 57 is arranged 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 elastic arm portion 57 functions as a bending space 59 for allowing the elastic displacement of the elastic arm portion 57, so that the outside of the movable outer conductor 56 The diameter dimension can be kept small.

A hook portion 83 protruding in the radial direction from the movable outer conductor 56 is formed on the base end portion 50P and the tip end portion 50T of the adapter 50. The second terminal portion 43 is formed with a receiving portion 78 that holds the adapter 50 in the second connector 30 by locking the hook portion 83. According to this configuration, the adapter 50 can be held in a suspended state with respect to the second connector 30 by locking the hooking portion 83 to 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. Therefore, workability is good.

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 a locked state with the receiving portion 78. The inclination angle α of the receiving portion 78 with respect to the connection direction between the second terminal portion 43 and the base end portion 50P is 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 portion 50P connection end portion. Greater angle. According to this configuration, it is possible to enhance the locking function between the hooking portion 83 and the receiving portion 78 while reducing the resistance when the base end portion 50P is guided to the receiving portion 78 in the locked state.

The movable outer conductor 56 of the base end portion 50P is formed with a tapered sliding contact portion 84 that slides into the tapered guide portion 79 in the process of engaging the hook portion 83 with the receiving portion 78. The inclination angle δ of the tapered sliding contact portion 84 with respect to the connection direction between the second terminal portion 43 and the base end portion 50P is the inclination angle δ of the tapered guide portion 79 with respect to the connection direction between the second terminal portion 43 and the base end portion 50P. It is the same angle as β. According to this configuration, the tapered sliding contact portion 84 is guided while in surface contact with the tapered guide portion 79, so that the tapered sliding contact portion 84 and the tapered guide portion 79 may be caught. The guide function is highly reliable.

The receiving portion 78 projects inward in the radial direction from the inner circumference of the second terminal portion 43. The base end portion 50P has an elastic arm portion 57. It projects radially outward from the hook portion 83 and the elastic arm portion 57. The protruding end of the hook portion 83 is in elastic contact with the inner circumference of the second terminal portion 43. According to this configuration, the protrusion dimension of the receiving portion 78 from the inner circumference of the second terminal portion 43 is surely secured as the locking allowance in the radial direction of the receiving portion 78 and the hooking portion 83, so that the contact reliability Is excellent.

The hooking portions 83 are arranged at a plurality of positions spaced apart from each other in the circumferential direction. In the region of the inner circumference of the second terminal portion 43 where the hook portion 83 can be contacted, the inner diameter portion is constant and the constant diameter portion 80 is continuous in the connection direction between the second terminal portion 43 and the base end portion 50P. Is formed. According to this configuration, even if the adapter 50 is tilted with respect to the second connector 30, the plurality of hooking portions 83 can surely come into contact with the fixed diameter portion 80 on the inner circumference of the second terminal portion 43.

The adapter 50 has a movable dielectric 53 and a movable outer conductor 56 that surrounds 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 a region 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 locking in the locking groove 81. .. According to this configuration, the rigidity of the elastic arm portion 57 does not decrease due to the formation of the locking claw 85, so that the contact reliability between the second terminal portion 43 and the hook portion 83 is high.

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 regulated by contacting the peripheral wall portion 34. According to this configuration, since the inclination of the adapter 50 is limited by the peripheral wall portion 34, the hook portion 83 can be reliably contacted with the inner circumference of the second terminal portion 43.

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 in a state where the second terminal portion 43 faces 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 for accommodating the first terminal portion 16 and an guiding portion 14. The guide portion 14 is arranged closer to the second connector 30 than the front surface 12S of the first terminal holding portion 12, and extends from the base end 14P toward the tip end 14T in a tapered shape. An interference avoiding 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.

According to this configuration, in the process of connecting the first connector 10 and the second connector 30, the tip portion 50T of the adapter 50 is guided by sliding contact with the guide portion 14 and is connected to the first terminal portion 16. When the first connector 10 and the second connector 30 are misaligned in a direction intersecting the opposite directions of the first terminal portion 16 and the second terminal portion 43, the posture of the adapter 50 is shifted between the two connectors 10 and 30. The tip portion 50T reaches the base end 14P of the guide portion 14 while being tilted with respect to the opposite direction of the guide portion 14, and the guide by the guide portion 14 ends. At this time, since the tip surface of the tip portion 50T is slanted with respect to the front surface 12S of the first terminal holding portion 12, the first terminal holding portion is immediately before the tip portion 50T reaches the base end 14P of the guiding portion 14. It protrudes to the front 12S side of the twelve.

Here, a space for accommodating the tip portion 50T is secured by the interference avoidance portion 75 between the base end 14P of the induction 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 induction 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 guided so as to face the first terminal portion 16. Connected to. Therefore, the connector device A of this embodiment has high reliability of connection operation.

The first terminal holding portion 12 is formed with a first terminal accommodating chamber 13 that opens in the front surface 12S of the first terminal holding portion 12 and accommodates the first terminal portion 16. A tapered guide surface 76 for guiding the tip portion 50T into the first terminal storage chamber 13 is formed at the opening edge of the first terminal storage chamber 13. According to this configuration, the tip portion 50T can be reliably attracted into the first terminal accommodating chamber 13.

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 surrounds the movable inner conductor 51 connected to the first inner conductor 17, the movable dielectric 53 surrounding the movable inner conductor 51, and the movable dielectric 53 on the inner circumference of the first outer conductor 22. It includes a movable outer conductor 56 to be connected. The tip surface of the movable dielectric 53 is exposed on the tip surface of the tip portion 50T. The first inner conductor 17 is arranged only in a region behind the inner end 76E of the guide surface 76.

According to this configuration, in the process of connecting the tip portion 50T to the first terminal portion 16, the connection between the movable outer conductor 56 and the first outer conductor 22 is started, so that the tip portion 50T is connected to the first terminal portion 16. At this point, the first inner conductor 17 is in non-contact with the tip of the tip 50T. Therefore, there is no possibility that the movable dielectric 53 interferes with the first terminal portion 16 in the process of advancing the connection between the tip portion 50T and the first terminal portion 16.

The cross-sectional shape of the guide surface 76 when cut at right angles to the opposite 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 1/2 of the pitch between the adjacent first terminal accommodating chambers 13. According to this configuration, the partition wall portion 77 that partitions the adjacent first terminal accommodating chambers 13 is formed to be recessed in an arc shape from the front surface 12S of the first terminal holding portion 12. As a result, the tip portion 50T is less likely to interfere with the front surface 12S of the first terminal holding portion 12.
