[0012] Referring to Figure 2, a structure 10 according to an embodiment of the present invention includes a connector assembly 12 and a substrate 16. The substrate 16 extends along a horizontal plane. The connector assembly 12 is connected to the substrate 16. Specifically, the connector assembly 12 is connected to the rear end of the substrate 16 in the front-to-rear direction parallel to the horizontal plane. The connector assembly 12 in Figures 1 to 7 is in a connected state in which the connector assembly 12 is connected to the substrate 16. On the other hand, the connector assembly 12 in Figures 8 and 9 is in a pre-connection state in which the connector assembly 12 is not yet connected to the substrate 16.

[0013] The horizontal plane in this embodiment is the XY plane, and the front-to-rear direction in this embodiment is the X direction. In this embodiment, "forward" is the +X direction, and "rear" is the -X direction. Terms such as horizontal plane and front-to-rear direction do not indicate an absolute positional relationship with respect to the ground, but merely indicate a relative positional relationship when the plane on which the board 16 extends is defined as the horizontal plane and the position of the connector assembly 12 with respect to this board 16 is defined as the rear.

[0014] 8 and 9, the substrate 16 is not particularly limited, and may be a flexible substrate or a rigid substrate.

[0015] 8 and 9, the substrate 16 has an upper surface 70U and a lower surface 70L in the vertical direction perpendicular to the horizontal plane. The upper surface 70U and the lower surface 70L are located at the upper end and the lower end, respectively, of the base body 70. In this embodiment, the vertical direction is the Z direction. In this embodiment, "upper" is the +Z direction, and "lower" is the -Z direction.

[0016] As shown in FIG. 8, two through holes 72 are formed in the substrate 16. Each of the through holes 72 penetrates the substrate 16 in the up-down direction. Each of the through holes 72 has a circular shape in the horizontal plane. As will be described later, the through holes 72 formed in this manner are used when screwing the connector assembly 12 to the substrate 16. The two through holes 72 are spaced apart from each other in the lateral direction, which is perpendicular to both the front-rear direction and the up-down direction, and are located at the same position as each other in the front-rear direction. In this embodiment, the lateral direction is the Y direction. The lateral direction is also the left-right direction. In this embodiment, the "right" is the +Y direction, and the "left" is the -Y direction.

[0017] The through holes 72 in this embodiment are formed as described above. However, the present invention is not limited to this. For example, the shape of each of the through holes 72 is not particularly limited. Furthermore, the number of through holes 72 may be three or more. In this case, two of the through holes 72 may be spaced apart from each other in the lateral direction or may be located at the same position as each other in the front-rear direction.

[0018] 8, a signal line 74, which is a conductive pattern, is formed on the upper surface 70U of the substrate 16. The signal line 74 extends in the front-rear direction and is located between the two through holes 72 in the lateral direction.

[0019] As shown in FIG. 9, a ground layer 78A, which is a conductive pattern, is formed on the lower surface 70L of the substrate 16 so as to cover the entire lower surface 70L.

[0020] Referring to FIG. 3 , the signal line 74 is connected to, for example, an antenna formed at the front end (not shown) of the substrate 16. In this case, the connector assembly 12 in the connected state transmits a signal to the antenna via the signal line 74. The transmitted signal is then transmitted from the antenna. Furthermore, a signal received by the antenna is transmitted to the connector assembly 12 via the signal line 74. The structure 10 of this embodiment is used, for example, as described above. However, the use of the structure 10 of the present invention is not particularly limited.

[0021] The substrate 16 of this embodiment has the above-described structure. However, the structure of the substrate 16 can be modified depending on the application of the structure 10. For example, the ground layer 78A may be formed partially on the lower surface 70L.

[0022] 9, the connector assembly 12 of this embodiment includes a coaxial connector 20, a fixed member 40, and two screws 60.

The number of central conductors in this embodiment is one. Except for the fact that the number of central conductors is one, the structure of the coaxial cable 80 is not particularly limited. For example, the outer conductor may be a braid made of thin metal wires or may be made of metal foil. For example, the coaxial cable 80 may be attached to the rear end of the coaxial connector 20 via a mating connector (not shown) attached to the coaxial cable 80.

[0027] 5, the center terminal 21 of this embodiment extends in the front-rear direction and has a contact portion 214. The contact portion 214 defines the front end of the center terminal 21 in the front-rear direction. When the coaxial connector 20 is attached to the coaxial cable 80, the center terminal 21 is connected to the center conductor of the coaxial cable 80. The center terminal 21 and the center conductor, which are connected to each other, transmit signals between each other.

[0028] As shown in FIG. 12 , the outer terminal 24 of this embodiment includes a front conductive member 242 and a rear conductive member 244. The front conductive member 242 is combined with the rear conductive member 244 and is located in front of the rear conductive member 244. The front conductive member 242 is in contact with the rear conductive member 244. The outer terminal 24 of this embodiment is composed of the two members described above. However, the present invention is not limited to this. For example, the front conductive member 242 and the rear conductive member 244 may be integral members.

[0029] 6, when the coaxial connector 20 is attached to the coaxial cable 80, the outer terminal 24 is connected to the outer conductor of the coaxial cable 80. For example, the rear conductive member 244 of the outer terminal 24 is electrically connected to the outer conductor. The outer terminal 24 and the outer conductor, which are connected to each other, have the same ground potential.

[0030] As shown in FIG. 9, the outer terminal 24 has a flange portion 25 and two protrusions 27.

The contact portion 214 extends forward in the front-rear direction beyond the end surface 26.

[0034] As shown in FIG. 9 , the two protrusions 27 of this embodiment are spaced apart from each other in the lateral direction. The contact portion 214 is located between the two protrusions 27 in the lateral direction. Each of the two protrusions 27 extends forward from the flange portion 25 in the front-rear direction. Each of the two protrusions 27 protrudes forward from the end surface 26. The two protrusions 27 of this embodiment have mirror-symmetric shapes with respect to a plane perpendicular to the lateral direction. That is, the two protrusions 27 are located at the same position in the up-down direction. Each of the protrusions 27 has an upper surface 27U and an upper surface 27U in the up-down direction. Each of the upper surfaces 27U and 27U is a plane parallel to the horizontal plane. The upper surface 27U defines the upper end of the protrusion 27 in the up-down direction. The lower surface 27L defines the lower end of the protrusion 27 in the up-down direction.

[0035] As shown in FIG. 9 , a screw hole 28 is formed in each of the protrusions 27 in this embodiment.

More specifically, the second receiving portion 272 is a part of the rear surface of the second portion 2702 in the front-to-rear direction.

[0045] As shown in Fig. 4, a central hole 29 is formed in the outer terminal 24 of this embodiment. The central hole 29 has a circular shape in the YZ plane. The central hole 29 is located between the two protrusions 27 in the lateral direction. The central terminal 21 is located at the center of the central hole 29 in the YZ plane.

[0046] As shown in FIG. 6, in a connected state in which the connector assembly 12 is connected to the board 16, a portion of the fixed member 40 is located below the board 16 in the up-down direction. With reference to FIGS. 2 and 9, in a connected state in which the connector assembly 12 is connected to the board 16, the fixed member 40 is in contact with the ground layer 78A of the board 16. As shown in FIG. 6, in the connected state, the fixed member 40 is in contact with the outer terminal 24. With reference to FIG. 14, the fixed member 40 is made of metal. More specifically, the fixed member 40 is formed by bending a punched metal plate. Note that the fixed member 40 is preferably subjected to a surface treatment such as gold plating to ensure reliable connection with the board 16 and the outer terminal 24.

[0047] As shown in FIG. 14, the fixed member 40 has a spring portion 43, a first contact portion 432, and two second contact portions 434.

[0048] 14, spring portion 43 in this embodiment is elastically deformable and supports first contact portion 432 and two second contact portions 434. Spring portion 43 defines the rear end of fixed member 40 in the front-rear direction.

[0049] As shown in Fig. 14, the first contact portion 432 of this embodiment faces rearward in the front-rear direction. As shown in Fig. 16, the first contact portion 432 is located rearward of both of the two second contact portions 434 in the front-rear direction. The first contact portion 432 is located between the two second contact portions 434 in the lateral direction. As shown in Fig. 5, in the connected state, the first contact portion 432 is in contact with the first receiving portion 252. That is, in the connected state, the first contact portion 432 and the first receiving portion 252 are electrically connected.

[0050] As shown in Fig. 15, each of the second contact portions 434 in this embodiment faces forward in the front-rear direction. As shown in Fig. 16, the two second contact portions 434 are spaced apart from each other in the lateral direction. With reference to Figs. 6 and 19, the distance in the front-rear direction between the first contact portion 432 and each of the two second contact portions 434 is variable due to elastic deformation of the spring portion 43.

[0051] 6, when the fixed member 40 is attached to the coaxial connector 20, the guide portion 273 guides the second contact portion 434 to the second receiving portion 272. In the connected state, the second contact portion 434 comes into contact with the second receiving portion 272. In the connected state, the second contact portion 434 of the metal fixed member 40 is electrically connected to the second receiving portion 272 of the metal flange portion 25. However, the present invention is not limited to this, and in the connected state, the second contact portion 434 and the second receiving portion 272 do not have to be electrically connected.

[0052] 6, in the connected state, due to elastic deformation of the spring portion 43, the first contact portion 432 is pressed against the first receiving portion 252, and the two second contact portions 434 are pressed against the second receiving portions 272 of the two protrusions 27, respectively. As a result, in the connector assembly 12 of this embodiment, the fixed member 40 is reliably connected to the outer terminal 24 of the coaxial connector 20. Therefore, when the connector assembly 12 of this embodiment is connected to the board 16, the ground layer 78A of the board 16 is electrically connected with high reliability to the first receiving portion 252 of the flange portion 25 of the outer terminal 24 via the fixed member 40. In other words, the connector assembly 12 of this embodiment can stably connect the outer terminal 24 to the ground layer 78A of the board 16, and can reliably improve the reflection characteristics of signals between the board 16 and the connector assembly 12.

[0053] As shown in FIG. 15, the spring portion 43 has a main portion 401 and two spring pieces 404.

[0054] 14, the main portion 401 of this embodiment has a flat plate shape perpendicular to the up-down direction. The main portion 401 defines the rear end of the fixed member 40 in the front-rear direction. The first contact portion 432 is provided on the main portion 401. The first contact portion 432 defines the rear end of the main portion 401 in the front-rear direction. The first contact portion 432 is part of the rear end surface of the main portion 401. As shown in FIG. 17, the main portion 401 has two grooves 406. The two grooves 406 are located at both ends of the main portion 401 in the lateral direction. Each of the grooves 406 extends in the lateral direction. As shown in FIGS. 16 and 17, the main portion 401 has an upper surface 40U and a lower surface 40L.

[0055] As shown in FIG. 15 , each spring piece 404 is provided with a second contact portion 434. The two spring pieces 404 extend upward from both lateral ends of the main portion 401. As shown in FIGS. 14 and 15 , each spring piece 404 is provided with a slit 4042 extending in the vertical direction. The slit 4042 allows the spring piece 404 to be elastically deformable. The two spring pieces 404 correspond to the two grooves 406, respectively. The slits 4042 of each spring piece 404 are connected to the corresponding grooves 406. Referring to FIG. 8 , the two spring pieces 404 correspond to the second receiving portions 272 of the two protrusions 27 of the coaxial connector 20, respectively. The two spring pieces 404 correspond to the guide portions 273 of the two protrusions 27 of the coaxial connector 20, respectively.

[0056] As shown in FIG. 19 , when the fixed member 40 is in a standalone state, the second contact portion 434 and the first contact portion 432 are spaced apart by a second distance D2 in the front-rear direction. That is, in the initial state in which the spring piece 404 is not elastically deformed, the fixed member 40 has the second distance D2 in the front-rear direction between the second contact portion 434 and the first contact portion 432. Referring to FIGS. 12 and 19 , the second distance D2 is greater than the first distance D1. As described above, the distances in the front-rear direction between the first contact portion 432 and each of the two second contact portions 434 are variable due to the elastic deformation of the spring portion 43. As a result, in the connected state, with the spring portion 43 elastically deformed, the spring portion 43 is sandwiched between the first receiving portion 252 and the second receiving portion 272 of the coaxial connector 20 via the first contact portion 432 and the second contact portion 434. 6 and 12, the distance between the second contact portion 434 and the first contact portion 432 in the connected state is equal to the first distance D1.

[0057] As shown in FIG. 14, each of the spring pieces 404 has two third contact portions 405 .

[0058] As shown in FIG. 14 , each of the third contact portions 405 in this embodiment faces inward in the lateral direction. Each of the third contact portions 405 is located lower than the upper end of the spring piece 404 in the vertical direction. Each of the third contact portions 405 is located above the first contact portion 432 in the vertical direction. In each of the spring pieces 404, the slit 4042 is located between the two third contact portions 405 in the front-rear direction. As shown in FIG. 16 , each of the third contact portions 405 is located laterally inward from the upper end of the spring piece 404. Each of the third contact portions 405 is located between the first contact portion 432 and the second contact portion 434 in the front-rear direction. Each of the third contact portions 405 is located forward of the first contact portion 432 in the front-rear direction. Each of the third contact portions 405 is located rearward of the second contact portion 434 in the front-rear direction. 18, each of the third contact portions 405 is located above the second contact portion 434 in the up-down direction. In each of the spring pieces 404, each of the third contact portions 405 is located inside the second contact portion 434 in the lateral direction. With reference to FIGS. 1 and 8, in the connected state, the third contact portion 405 is in contact with the third receiving portion 276 in the lateral direction.

[0059] 14, the fixed member 40 has a pressed portion 42. As will be described later, the pressed portion 42 is a portion that is pressed against the board 16 in the connected state. According to the present embodiment, the intermediate portion in the lateral direction of the upper surface 40U mainly functions as the pressed portion 42.

[0060] As shown in FIG. 16 , the fixed member 40 of this embodiment has two fixing holes 45. Each of the fixing holes 45 penetrates the fixed member 40 in the up-down direction. Each of the fixing holes 45 has a substantially circular shape in the horizontal plane. Referring to FIG. 9 , the fixing holes 45 are provided at positions corresponding to the passage holes 72 of the substrate 16 in the horizontal plane. That is, the two fixing holes 45 are spaced apart from each other in the lateral direction and are at the same position as each other in the front-to-rear direction. Referring to FIG. 17 , the fixing holes 45 correspond to the grooves 406, respectively. Each of the fixing holes 45 is connected to the corresponding groove 406. Two spring pieces 404 correspond to the two fixing holes 45, respectively. The slits 4042 of the spring pieces 404 are connected to the corresponding fixing holes 45 via the corresponding grooves 406. The slit 4042 of one spring piece 404 is not connected to the slit 4042 of the other spring piece 404 .

[0061] The fixed member 40 of this embodiment has the structure described above. However, the present invention is not limited to this. For example, the shape of each of the fixing holes 45 is not particularly limited. Furthermore, the number of fixing holes 45 may be three or more.

[0062] 6, the connector assembly 12 is connected to a substrate 16 to form the structure 10. The substrate 16 of the structure 10 is positioned between the protrusion 27 of the outer terminal 24 and the fixed member 40 in the up-down direction. Referring to FIG. 3, the signal wire 74 of the substrate 16 is pressed from below by the fixed member 40, and is pressed against and comes into contact with the contact portion 214 of the center terminal 21, thereby electrically connecting the contact portion 214 and the signal wire 74. However, the present invention is not limited to this, and the contact portion 214 and the signal wire 74 may also be connected by soldering.

[0063] 9, each of the screws 60 in this embodiment is a right-handed screw 60 made of metal. The screws 60 are provided corresponding to the respective through holes 72 of the substrate 16. The number of screws 60 in this embodiment is two. However, the present invention is not limited to this. For example, three or more screws 60 having different shapes may be provided. Referring to FIGS. 2 and 9, in the connected state, the screws 60 pass through the fixing holes 45 and the through holes 72 and are screwed into the respective screw holes 28 of the protrusion 27. As a result, the screws 60 are fixed to the respective protrusions 27 while pressing the fixed member 40 against the ground layer 78A of the substrate 16.

[0064] The connector assembly 12 of this embodiment is connected to the substrate 16 by the connection method described below. The connection method described below is merely an example and can be modified as necessary.

[0065] Referring to Figures 8 and 9, first, the coaxial connector 20 and the substrate 16 are arranged in the vertical direction so that the lower surface 27L of the protrusion 27 of the coaxial connector 20 and the upper surface 70U of the substrate 16 are in contact with each other in the vertical direction, and the screw hole 28 of the coaxial connector 20 and the through hole 72 of the substrate 16 are in the same position as each other in the horizontal plane.

[0066] Next, the fixed member 40 is positioned vertically relative to the coaxial connector 20 and the substrate 16 so that the lower surface 70L of the substrate 16 and the upper surface 40U of the fixed member 40 face each other in the vertical direction, and so that each of the guide portions 273 of the coaxial connector 20 and the second contact portion 434 of the corresponding spring piece 404 of the fixed member 40 are in the same position relative to each other in the horizontal plane.

[0067] Thereafter, when the fixed member 40 is brought closer to the coaxial connector 20 and the substrate 16 in the vertical direction, the second contact portion 434 of the fixed member 40 comes into contact with the guide portion 273 of the coaxial connector 20, and the third contact portion 405 of the fixed member 40 comes into contact with the protrusion 27 of the coaxial connector 20.

[0068] In this state, the fixed member 40 is brought even closer to the coaxial connector 20 and the board 16 in the vertical direction. Then, the spring portion 43 of the fixed member 40 elastically deforms, and the first contact portion 432 of the fixed member 40 moves onto the first receiving portion 252 of the coaxial connector 20, while the second contact portion 434 of the fixed member 40 climbs over the guide portion 273 of the coaxial connector 20 and onto the corresponding second receiving portion 272 of the coaxial connector 20. At this time, the third contact portion 405 of the fixed member 40 moves onto the third receiving portion 276 of the coaxial connector 20. Furthermore, at this time, the upper surface 40U of the fixed member 40 comes into contact with the lower surface 70L of the board 16 in the vertical direction. Since the guide portion 273 extends upward and rearward as described above, the fixed member 40 can be smoothly attached to the coaxial connector 20.

[0069] In this state, the first contact portion 432 of the fixed member 40 is in contact with the first receiving portion 252 of the coaxial connector 20 in the front-rear direction, the second contact portion 434 of the fixed member 40 is in contact with the corresponding second receiving portion 272 of the coaxial connector 20 in the front-rear direction, and the third contact portion 405 of the fixed member 40 is in contact with the third receiving portion 276 of the coaxial connector 20 in the lateral direction. Also, in this state, due to the elastic deformation of the spring portion 43, the first contact portion 432 is pressed against the first receiving portion 252, and the two second contact portions 434 are pressed against the second receiving portions 272 of the two protrusions 27, respectively.

[0070] Thereafter, the screws 60 are threaded through the fixing holes 45 of the fixed member 40 and the through holes 72 of the board 16 into the screw holes 28 of the protruding portion 27 of the coaxial connector 20. This brings the connector assembly 12 into a connected state with the board 16. In this connected state, the contact portion 214 of the center terminal 21 comes into contact with the signal line 74 of the board 16.

[0071] As shown in FIG. 6, a portion of the fixed member 40 is located below the substrate 16 in the vertical direction in the connected state. Referring to FIGS. 2 and 9, the heads of the screws 60 are pressed against the lower surface 40L of the fixed member 40 in the connected state, applying upward pressure to the fixed member 40. The pressed upper surface 40U of the fixed member 40 presses the substrate 16 against the lower surface 27L of the protruding portion 27. As a result, the substrate 16 is sandwiched between the protruding portion 27 and the fixed member 40. In particular, the pressed portion 42 (see FIG. 8) of the fixed member 40 is pressed against a contact region of the substrate 16 located below the contact portion 214 of the center terminal 21, supporting the contact region from below. In particular, if the substrate 16 is a flexible substrate that easily bends, the contact region of the substrate 16 will not bend even when subjected to a force from above. Furthermore, the fixed member 40 is pressed against the ground layer 78A of the substrate 16 in the connected state.

[0072] That is, in the connected state, the screws 60 pass through the fixing holes 45 and the through holes 72 and are screwed into the screw holes 28 of the protrusions 27, respectively, so that the screws 60 are fixed to the protrusions 27 while pressing the fixed members 40 against the ground layer 78A of the substrate 16.

[0073] 4 and 9, the outer terminal 24 is grounded to the ground layer 78A on the lower surface 70L of the substrate 16 via the protrusion 27, the screw 60, and the fixed member 40 in the connected state.

[0074] As described above, in the outer terminal 24 of the present embodiment, the second receiving portion 272 is part of the rear surface in the front-rear direction of the second portion 2702 of the protruding portion 27, but the present invention is not limited to this. Specifically, the outer terminal 24 may be modified so that a groove or recess that opens downward is provided in the protruding portion 27, and the rearward-facing surface of the inner surface of the groove or recess functions as the second receiving portion 272. In this case, in the connected state, the spring piece 404 of the fixed member 40 is received inside the groove or recess from below, and the second contact portion 434 of the spring piece 404 comes into contact in the front-rear direction with the second receiving portion 272, which is the rearward-facing surface of the inner surface of the groove or recess.

[0075] The configuration of the fixed member 40 of the connector assembly 12 is not limited to the one described above, and for example, the following modifications are possible.

[0076] 20, a fixed member 40A according to the first modified example of the present invention has a spring portion 43A, a first contact portion 432, and two second contact portions 434. Here, the first contact portion 432 and the second contact portion 434 are the same as those in the above-described embodiment, and therefore detailed description thereof will be omitted.

[0077] 20, the spring portion 43A of this modified example is elastically deformable and supports a first contact portion 432 and two second contact portions 434. The spring portion 43A defines the rear end of the fixed member 40A in the front-rear direction.

[0078] 9 and 20 , in a connected state in which a connector assembly (not shown) according to a first modified example of the present invention, which includes a coaxial connector 20, a fixed member 40A, and two screws 60, is connected to a board 16, the first contact portion 432 is pressed against the first receiving portion 252 due to elastic deformation of the spring portion 43A, and the two second contact portions 434 are pressed against the second receiving portions 272 of the two protrusions 27, respectively. As a result, in the connector assembly of this modified example, the fixed member 40A is also reliably connected to the outer terminal 24 of the coaxial connector 20. Therefore, when the connector assembly of this modified example is connected to the board 16, the ground layer 78A of the board 16 is electrically connected with high reliability to the first receiving portion 252 of the flange portion 25 of the outer terminal 24 via the fixed member 40A. In other words, in the connector assembly of this modified example, the outer terminal 24 can also be stably connected to the ground layer 78A of the substrate 16, thereby reliably improving the reflection characteristics of signals between the substrate 16 and the connector assembly.

[0079] 20, the spring portion 43A has a main portion 401A and two spring pieces 404. The spring pieces 404 of this modified example are similar to the spring pieces 404 of the above-described embodiment, and therefore a detailed description thereof will be omitted.

[0080] 20, the main portion 401A of this modified example has a flat plate shape that is perpendicular to the up-down direction. The main portion 401A defines the rear end of the fixed member 40A in the front-to-rear direction. The first contact portion 432 is provided on the main portion 401A. The first contact portion 432 defines the rear end of the main portion 401A in the front-to-rear direction. The first contact portion 432 is a part of the rear end surface of the main portion 401A. Unlike the above-described embodiment, the main portion 401A of this modified example does not have the groove 406.

[0081] 20, when the fixed member 40A is in a standalone state, the second contact portion 434 and the first contact portion 432 are spaced a second distance apart in the front-rear direction. That is, when the fixed member 40A is in an initial state in which the spring pieces 404 are not elastically deformed, the second contact portion 434 and the first contact portion 432 are spaced a second distance apart in the front-rear direction. With reference to FIGS. 12 and 20, the second distance is greater than the first distance D1. As a result, when the spring portion 43A is elastically deformed in the connected state, the spring portion 43A is sandwiched between the first receiving portion 252 and the second receiving portion 272 of the coaxial connector 20 via the first contact portion 432 and the second contact portion 434.

[0082] 20, a fixed member 40A has a pressed portion 42. The pressed portion 42 of this modified example is similar to the pressed portion 42 of the above-described embodiment, and detailed description thereof will be omitted.

[0083] As shown in FIG. 21 , two fixing holes 45A are provided in the fixed member 40A of this modified example. Each of the fixing holes 45A penetrates the fixed member 40A in the up-down direction. Each of the fixing holes 45A has a circular shape in the horizontal plane. Referring to FIGS. 9 and 20 , the fixing holes 45A are provided at positions corresponding to the passage holes 72 of the substrate 16 in the horizontal plane. That is, the two fixing holes 45A are separated from each other in the lateral direction and are in the same position as each other in the front-to-rear direction. The two spring pieces 404 correspond to the two fixing holes 45A, respectively. Note that, as described above, the main portion 401A of this modified example does not have the groove 406, and therefore the slits 4042 of the spring pieces 404 of this modified example are not connected to the corresponding fixing holes 45A.

[0084] 22, a fixed member 40B according to the second modified example of the present invention has a spring portion 43B, a first contact portion 432, and two second contact portions 434. Here, the first contact portion 432 and the second contact portion 434 are the same as those in the above-described embodiment, and therefore detailed description thereof will be omitted.

[0085] 22, the spring portion 43B of this modified example is elastically deformable and supports the first contact portion 432 and two second contact portions 434. The spring portion 43B defines the rear end of the fixed member 40B in the front-rear direction.

[0086] 9 and 22, in a connected state in which a connector assembly (not shown) according to a second modified example of the present invention, which includes a coaxial connector 20, a fixed member 40B, and two screws 60, is connected to a board 16, the first contact portion 432 is pressed against the first receiving portion 252 due to elastic deformation of the spring portion 43B, and the two second contact portions 434 are pressed against the second receiving portions 272 of the two protrusions 27, respectively. As a result, in the connector assembly of this modified example, the fixed member 40B is also reliably connected to the outer terminal 24 of the coaxial connector 20. Therefore, when the connector assembly of this modified example is connected to the board 16, the ground layer 78A of the board 16 is electrically connected with high reliability to the first receiving portion 252 of the flange portion 25 of the outer terminal 24 via the fixed member 40B. In other words, in the connector assembly of this modified example, the outer terminal 24 can also be stably connected to the ground layer 78A of the substrate 16, thereby reliably improving the reflection characteristics of signals between the substrate 16 and the connector assembly.

[0087] 22, the spring portion 43B has a main portion 401B and two spring pieces 404. The spring pieces 404 of this modified example are similar to the spring pieces 404 of the above-described embodiment, and therefore detailed description thereof will be omitted.

[0088] 22, the main portion 401B of this modified example defines the rear end of the fixed member 40B in the front-rear direction. The main portion 401B has a first main portion 4012 and a second main portion 4014. The first main portion 4012 is located rearward of the second main portion 4014 in the front-rear direction. The first main portion 4012 and the second main portion 4014 are separated by a groove 4016. That is, the groove 4016 is located between the first main portion 4012 and the second main portion 4014 in the front-rear direction. The first contact portion 432 is provided on the main portion 401B. Specifically, the first contact portion 432 is provided on the first main portion 4012. The first contact portion 432 defines the rear end of the main portion 401B in the front-rear direction. The first contact portion 432 defines the rear end in the front-rear direction of the first main portion 4012. The first contact portion 432 is part of the rear end surface of the main portion 401B. That is, the first contact portion 432 is part of the rear end surface of the first main portion 4012.

[0089] 22, when the fixed member 40B is in a standalone state, the second contact portion 434 and the first contact portion 432 are spaced a second distance apart in the front-rear direction. That is, when the fixed member 40B is in an initial state in which the spring pieces 404 are not elastically deformed, the second contact portion 434 and the first contact portion 432 are spaced a second distance apart in the front-rear direction. With reference to FIGS. 12 and 22, the second distance is greater than the first distance D1. As a result, when the spring portion 43B is elastically deformed in the connected state, the spring portion 43B is sandwiched between the first receiving portion 252 and the second receiving portion 272 of the coaxial connector 20 via the first contact portion 432 and the second contact portion 434.

[0090] 22, a fixed member 40B has a pressed portion 42. The pressed portion 42 of this modification is similar to the pressed portion 42 of the above-described embodiment, and detailed description thereof will be omitted.

[0091] As shown in FIG. 23 , two fixing holes 45B are provided in the fixed member 40B of this modified example. Each of the fixing holes 45B penetrates the fixed member 40B in the up-down direction. Each of the fixing holes 45B has a circular shape in the horizontal plane. Referring to FIGS. 9 and 22 , the fixing holes 45B are provided at positions corresponding to the passage holes 72 of the substrate 16 in the horizontal plane. That is, the two fixing holes 45B are spaced apart from each other in the horizontal direction and are at the same position as each other in the front-to-rear direction. Two spring pieces 404 correspond to the two fixing holes 45B, respectively. The slits 4042 of the spring pieces 404 of this modified example are not connected to the corresponding fixing holes 45B. The slits 4042 of the two spring pieces 404 are connected to each other in the horizontal direction. That is, the slits 4042 of the two spring pieces 404 are connected to each other via the groove 4016. As a result, the spring portion 43B of this modified example is more easily elastically deformed than the spring portions 43, 43A of the above-described embodiment and first modified example.

[0092] 24, a fixed member 40C according to a third modified example of the present invention has a spring portion 43C having a main portion 401C and two spring pieces 404, a first contact portion 432C, and two second contact portions 434. Here, the spring portion 43C and the second contact portions 434 are the same as those in the above-described embodiment, and therefore detailed description thereof will be omitted.

[0093] As shown in FIG. 24, the first contact portion 432C of this modified example faces rearward in the front-rear direction. The first contact portion 432C is located rearward of both of the two second contact portions 434 in the front-rear direction. The first contact portion 432C is located between the two second contact portions 434 in the lateral direction. The first contact portion 432C is composed of one protrusion 433. The protrusion 433 is located at the center of the fixed member 40C in the lateral direction. The protrusion 433 is supported by the spring portion 43C so as to protrude rearward in the front-rear direction. Referring to FIGS. 24 and 5, in a connected state in which a connector assembly (not shown) according to a third modified example of the present invention, which includes a coaxial connector 20, a fixed member 40C, and two screws 60, is connected to the board 16, the first contact portion 432C contacts the first receiving portion 252. That is, in the connected state, the first contact portion 432C and the first receiving portion 252 are electrically connected. With reference to Fig. 24 and Fig. 3, in the connected state, the convex portion 433 is located between the two protrusions 27 in the horizontal direction. In the connected state, the convex portion 433 is located at the same position as the contact portion 214 of the center terminal 21 in the horizontal direction. In the connected state, the convex portion 433 is located near the contact portion 214 of the center terminal 21.

[0094] 8 and 24, in the connected state, due to elastic deformation of the spring portion 43C, the first contact portion 432C is pressed against the first receiving portion 252, and the two second contact portions 434 are pressed against the second receiving portions 272 of the two protrusions 27, respectively. As a result, in the connector assembly of this modified example, the fixed member 40C is also reliably connected to the outer terminal 24 of the coaxial connector 20. Therefore, when the connector assembly of this modified example is connected to the board 16, the ground layer 78A of the board 16 is electrically connected with high reliability to the first receiving portion 252 of the flange portion 25 of the outer terminal 24 via the fixed member 40C. In other words, in the connector assembly of this modified example, the outer terminal 24 can be stably connected to the ground layer 78A of the board 16, and the reflection characteristics of signals between the board 16 and the connector assembly can be reliably improved.

[0095] Furthermore, as described above, in the connected state, the first contact portion 432C located near the contact portion 214 of the center terminal 21 of the coaxial connector 20 is pressed in the front-rear direction against the first receiving portion 252. As a result, the fixed member 40C of this modified example is always in contact with the flange portion 25 near the contact portion 214 of the center terminal 21 of the coaxial connector 20 in the connected state.

[0096] 25, a fixed member 40D according to a fourth modified example of the present invention has a spring portion 43D having a main portion 401D and two spring pieces 404, a first contact portion 432D, and two second contact portions 434. Here, the spring portion 43D and the second contact portions 434 are the same as those in the above-described embodiment, and therefore detailed description thereof will be omitted.

[0097] As shown in FIG. 25, the first contact portion 432D of this modified example faces rearward in the front-rear direction. The first contact portion 432D is located rearward of both of the two second contact portions 434 in the front-rear direction. The first contact portion 432D is located between the two second contact portions 434 in the lateral direction. The first contact portion 432D is made up of two protrusions 433D. Note that the present invention is not limited to this, and the first contact portion 432D may be made up of at least one protrusion 433D. The two protrusions 433D are arranged mirror-symmetrically with respect to a plane perpendicular to the lateral direction. Each of the protrusions 433D is supported by a spring portion 43D so as to protrude rearward in the front-rear direction. 25 and 5, in a connected state in which a connector assembly (not shown) according to a fourth modification of the present invention, which includes a coaxial connector 20, a fixed member 40D, and two screws 60, is connected to a board 16, the first contact portion 432D is in contact with the first receiving portion 252. That is, in the connected state, the first contact portion 432D and the first receiving portion 252 are electrically connected. With reference to FIGS. 25 and 3, in the connected state, the two protrusions 433D are located on both sides of the contact portion 214 of the center terminal 21 in the lateral direction. In the connected state, each of the protrusions 433D is located around the contact portion 214 of the center terminal 21.

[0098] 25 and 8, in the connected state, due to elastic deformation of the spring portion 43D, the first contact portion 432D is pressed against the first receiving portion 252, and the two second contact portions 434 are pressed against the second receiving portions 272 of the two protrusions 27, respectively. As a result, in the connector assembly of this modified example, the fixed member 40D is also reliably connected to the outer terminal 24 of the coaxial connector 20. Therefore, when the connector assembly of this modified example is connected to the board 16, the ground layer 78A of the board 16 is electrically connected with high reliability to the first receiving portion 252 of the flange portion 25 of the outer terminal 24 via the fixed member 40D. In other words, in the connector assembly of this modified example, the outer terminal 24 can also be stably connected to the ground layer 78A of the board 16, and the reflection characteristics of signals between the board 16 and the connector assembly can be reliably improved.

[0099] Furthermore, as described above, in the connected state, the first contact portion 432D located around the contact portion 214 of the center terminal 21 of the coaxial connector 20 is pressed in the front-rear direction against the first receiving portion 252. This ensures that the fixed member 40D of this modified example always comes into contact with the flange portion 25 around the contact portion 214 of the center terminal 21 of the coaxial connector 20 in the connected state.
