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 portion of the substrate 16 in the front - rear direction parallel to the horizontal plane. The connector assemblies 12 from FIG. 1 to FIG. 7 are in a connected state where the connector assembly 12 is connected to the substrate 16. On the other hand, the connector assemblies 12 in FIGS. 8 and 9 are in a pre - connection state before the connector assembly 12 is connected to the substrate 16.

[0017]

[0018] Referring to FIGS. 8 and 9, the substrate 16 is not particularly limited and may be a flexible substrate or a rigid substrate.

[0019] As shown in FIGS. 8 and 9, the substrate 16 has an upper surface 70U and a lower surface 70L in the up - down direction orthogonal to the horizontal plane. The upper surface 70U and the lower surface 70L are respectively located at the upper end and the lower end of the base body 70. The up - down direction of the present embodiment is the Z direction. In the present embodiment, “upward” is the +Z direction and “downward” is the -Z direction.

[0020] 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 vertical direction. Each of the through holes 72 has a circular shape in the horizontal plane. The through holes 72 formed in this way are used when screwing the connector assembly 12 to the substrate 16, as will be described later. The two through holes 72 are separated from each other in the lateral direction orthogonal to both the front-rear direction and the vertical direction, and are in the same position as each other in the front-rear direction. The lateral direction in the present embodiment is the Y direction. Also, the lateral direction is the left-right direction. In the present embodiment, "rightward" is the +Y direction, and "leftward" is the -Y direction.

[0021] The through holes 72 of the present 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. Also, the number of the through holes 72 may be three or more. In this case, two of the through holes 72 may be separated from each other in the lateral direction and may be in the same position as each other in the front-rear direction.

[0022] As shown in FIG. 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.

[0023] 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.

[0024] Referring to FIG. 3, the signal line 74 is connected to an antenna formed at the front end portion (not shown) of the substrate 16, for example. 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 transmitted from the antenna. Also, the signal received by the antenna is transmitted to the connector assembly 12 via the signal line 74. The structure 10 of the present embodiment is used as described above, for example. However, the use of the structure 10 in the present invention is not particularly limited.

[0025] As shown in FIG. 8, the substrate 16 includes two lands 76X that are conductive patterns. Two via holes 72 penetrate the lands 76X respectively. A plurality of via holes 77X are formed in each of the lands 76X. Each of the via holes 77X penetrates the base body 70 and the land 76X in the vertical direction, whereby each of the lands 76X is electrically connected to the ground layer 78A (see FIG. 9) of the lower surface 70L.

[0026] The substrate 16 of the present embodiment has the above-described structure. However, the structure of the substrate 16 can be deformed according to the use of the structure 10. For example, the ground layer 78A may be partially formed on the lower surface 70L.

[0027] Referring to FIG. 9, the connector assembly 12 of the present embodiment includes a coaxial connector 20, a member to be fixed 40, and two fixing members (screws) 60. The connector assembly 12 of the present embodiment includes only the above-described members. However, the present invention is not limited thereto.

The main body portion 212 is an intermediate portion of the central terminal 21 in the front-rear direction. The contact portion 214 extends forward from the main body portion 212. As shown in FIG. 10, the contact portion 214 is bent downward in the vertical direction after the coaxial connector 20 is assembled. That is, the contact portion 214 extends forward and downward in the pre-connection state before the connector assembly 12 is connected to the substrate 16. The contact portion 214 defines the front end of the central terminal 21 in the front-rear direction. As shown in FIG. 5, the connection portion 218 has a socket shape and extends rearward from the main body portion 212.. The connection portion 218 defines the rear end of the central terminal 21 in the front-rear direction. When the coaxial connector 20 is attached to the coaxial cable 80, the central terminal 21 is connected to the central conductor 82 of the coaxial cable 80. Specifically, the connection portion 218 of the central terminal 21 is electrically connected to the central conductor 82. The mutually connected central terminal 21 and central conductor 82 transmit signals to each other.

[0033] The center terminal 21 of the present embodiment has the above-described structure. However, as long as the center terminal 21 has the contact portion 214 extending along the front-rear direction, the structure of the center terminal 21 can be deformed as necessary.

[0034] As shown in FIG. 5, the outer terminal 24 of the present 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 the present embodiment is composed of the above two members. However, the present invention is not limited thereto. For example, the front conductive member 242 and the rear conductive member 244 may be integrally formed with each other.

[0035] Referring to FIG. 5, when the coaxial connector 20 is attached to the coaxial cable 80, the outer terminal 24 is connected to the outer conductor 86 of the coaxial cable 80. For example, the rear conductive member 244 of the outer terminal 24 is electrically connected to the outer conductor 86. The outer terminal 24 and the outer conductor 86 connected to each other have the same ground potential.

[0036] As shown in FIG. 9, the outer terminal 24 has a flange portion 25 and two protruding portions 27.

[0037] As shown in FIGS. 8 and 9, the flange portion 25 of the present embodiment has a first receiving portion 252 and two second receiving portions 254.

Referring to FIG. 6, as will be described later, when the member 40 to be fixed is attached to the coaxial connector 20, the attracting portion 256 guides the second contact portion 405 to the second receiving portion 254. In the connected state, the second contact portion 405 contacts the second receiving portion 254. In the connected state, the second contact portion 405 of the metal member 40 to be fixed is electrically connected to the second receiving portion 254 of the metal flange portion 25. Note that the present invention is not limited thereto, and in the connected state, the second contact portion 405 and the second receiving portion 254 may not be electrically connected.

[0057] As shown in FIG. 11, the member 40 to be fixed has a first distance D1 between the second contact portion 405 and the first contact portion 402 in the front - rear direction in its single state. That is, the member 40 to be fixed has a first distance D1 between the second contact portion 405 and the first contact portion 402 in the front - rear direction in the initial state where the spring portion 404 is not elastically deformed. When there is one spring portion 404, the member 40 to be fixed only needs to have a first distance D1 between the second contact portion 405 supported by the spring portion 404 and the first contact portion 402 in the front - rear direction in its single state. That is, when at least one of the two second contact portions 405 is supported by the spring portion 404, the member 40 to be fixed only needs to have a first distance D1 between the at least one second contact portion 405 and the first contact portion 402 in the front - rear direction in its single state. Referring to FIGS. 10 and 11, the first distance D1 is smaller than the second distance D2. Thereby, in the connected state, with the spring portion 404 elastically deformed, the flange portion 25 is sandwiched between the first contact portion 402 and the second contact portion 405 of the member 40 to be fixed via the first receiving portion 252 and the second receiving portion 254.

[0058] Referring to FIG. 6, in the connected state, the two spring portions 404 press the two second contact portions 405 against the two second receiving portions 254 respectively. More specifically, in the connected state, the spring portion 404 presses the second contact portion 405 against the second receiving portion 254, and the second contact portion 405 receives a reaction force from the second receiving portion 254 due to the pressing. In the connected state, the first contact portion 402 is pressed against the first receiving portion 252 along the front-rear direction by the reaction force. Thereby, in the connector assembly 12 of the present embodiment, the member 40 to be fixed is reliably connected to the outer terminal 24 of the coaxial connector 20. Therefore, when the connector assembly 12 of the present embodiment is connected to the substrate 16, the ground layer 78A of the substrate 16 is electrically connected to the first receiving portion 252 of the flange portion 25 of the outer terminal 24 via the member 40 to be fixed with high reliability. That is, the connector assembly 12 of the present embodiment can stably connect the outer terminal 24 to the ground layer 78A of the substrate 16, and can surely improve the signal reflection characteristics between the substrate 16 and the connector assembly 12.

[0059] As shown in FIG. 8, the member 40 to be fixed has a portion 42 to be pressed. As will be described later, the portion 42 to be pressed is a portion that is pressed against the substrate 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 portion 42 to be pressed.

[0060] As shown in FIG. 9, two fixing holes 45 are formed in the member 40 to be fixed of the present embodiment. Each of the fixing holes 45 penetrates the member 40 to be fixed in the vertical direction. As shown in FIG. 11, each of the fixing holes 45 has a circular shape in the horizontal plane. Referring to FIG. 8, the fixing holes 45 are provided at positions corresponding to the through holes 72 of the substrate 16 in the horizontal plane respectively. That is, the two fixing holes 45 are separated from each other in the lateral direction and are at the same position as each other in the front-rear direction.

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

[0062] Referring to FIG. 7, the connector assembly 12 is connected to the substrate 16 to form the structure 10. The substrate 16 of the structure 10 is positioned between the protruding portion 27 of the outer terminal 24 and the fixed member 40 in the vertical direction. Referring to FIGS. 3 and 5, the signal line 74 of the substrate 16 is pressed from below by the fixed member 40 and pressed against the contact portion 214 of the center terminal 21 to make contact, and the contact portion 214 and the signal line 74 are electrically connected. Note that the present invention is not limited thereto, and the contact portion 214 and the signal line 74 may be connected by soldering.

[0063] As shown in FIG. 9, the two fixing members 60 of the present embodiment have the same shape as each other. More specifically, each of the fixing members 60 of the present embodiment is a screw 60. That is, a screw (not shown) is cut in each of the fixing members 60. More specifically, each of the fixing members 60 is a right-handed screw 60 made of metal. The fixing members 60 are provided corresponding to the through holes 72 of the substrate 16, respectively. That is, the number of the fixing members 60 of the present embodiment is two. However, the present invention is not limited thereto. For example, three or more fixing members 60 having different shapes from each other may be provided. Referring to FIGS. 2 and 9, each of the fixing members 60 passes through the fixing hole 45 of the fixed member 40 and the through hole 72 of the substrate 16 in the connected state and is screwed into the screw hole 28.

[0064] The connector assembly 12 of the present 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 FIGS. 8 and 9, first, the coaxial connector 20 and the substrate 16 are arranged in the vertical direction such that the lower surface 27L of the protruding portion 27 of the coaxial connector 20 contacts the upper surface 70U of the substrate 16 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 arranged in the vertical direction with respect to the coaxial connector 20 and the substrate 16 such that the lower surface 70L of the substrate 16 faces the upper surface 40U of the fixed member 40 in the vertical direction, and each of the attracting portions 256 of the coaxial connector 20 and the second contact portions 405 of the corresponding spring portions 404 of the fixed member 40 are in the same position as 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 405 of the fixed member 40 contacts the attracting portion 256 of the coaxial connector 20.

[0068] In this state, when the fixed member 40 is further brought closer to the coaxial connector 20 and the substrate 16 in the vertical direction, the second contact portion 405 of the fixed member 40 climbs over the attracting portion 256 of the coaxial connector 20 and rides on the corresponding second receiving portion 254 of the coaxial connector 20, and the upper surface 40U of the fixed member 40 contacts the lower surface 70L of the substrate 16 in the vertical direction.

[0069] In this state, the first contact portion 402 of the fixed member 40 is in contact with the first receiving portion 252 of the coaxial connector 20 in the front-rear direction, and the second contact portion 405 of the fixed member 40 is in contact with the corresponding second receiving portion 254 of the coaxial connector 20 in the front-rear direction. Also, in this state, each of the spring portions 404 presses the corresponding second contact portion 405 against the corresponding second receiving portion 254, and the second contact portion 405 receives a reaction force from the second receiving portion 254 due to the pressing. Further, in this state, the first contact portion 402 is pressed against the first receiving portion 252 along the front-rear direction by the reaction force.

[0070] Thereafter, each of the fixing members 60 is screwed into the screw holes 28 of the protruding portions 27 of the coaxial connector 20 through the fixing holes 45 of the member to be fixed 40 and the through holes 72 of the substrate 16. Thereby, the connector assembly 12 is in a connected state connected to the substrate 16.

[0071] Referring to FIGS. 3 and 5, the contact portion 214 of the center terminal 21 contacts the signal line 74 of the substrate 16 in the connected state. Here, as described above, in the state before connection, the contact portion 214 of the center terminal 21 extends forward and downward, and the lower end of the contact portion 214 is located below the lower surface 27L of the protruding portion 27. Thereby, the contact portion 214 abuts against the signal line 74 of the substrate 16 in the connected state and elastically deforms. The contact portion 214 is pressed against the signal line 74 from above by the restoring force generated due to the elastic deformation.

[0072] As shown in FIG. 5, the member to be fixed 40 is located below the substrate 16 in the vertical direction in the connected state. Referring to FIGS. 5 and 9, the heads of the respective fixing members 60 are pressed against the lower surface 40L of the member to be fixed 40 in the connected state, and the member to be fixed 40 is pressurized upward. The upper surface 40U of the member to be fixed 40 pressurized in this way 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 member to be fixed 40. In particular, the pressed portion 42 (see FIG. 8) of the member to be fixed 40 is pressed against the contact region located below the contact portion 214 of the center terminal 21 of the substrate 16, and supports the contact region from below. In particular, when the substrate 16 is a flexible substrate that is easily bent, the contact region of the substrate 16 does not bend even when receiving a force from above. Further, the member to be fixed 40 is pressed against the ground layer 78A of the substrate 16 in the connected state to make a predetermined plane orthogonal to the vertical direction.

[0073] That is, the two fixing members 60 are fixed to the two protruding portions 27 of the outer terminal 24 through the two through holes 72 of the substrate 16 while pressing the member to be fixed 40 against the ground layer 78A of the substrate 16 to make a predetermined plane orthogonal to the vertical direction in the connected state.

[0074] Referring to FIGS. 4 and 9, in the connected state, 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 fixing member 60, and the member to be fixed 40.

[0075] In addition to the various modifications already described, the structure 10 of the present embodiment can be further modified in various ways. Hereinafter, three modifications of the structure 10 will be described focusing on the differences from the structure 10.

[0076] (First Modification) Comparing FIG. 12 with FIG. 6, the structure 10A according to the first modification includes a connector assembly 12A and a substrate 16. The substrate 16 of this modification is the same as the substrate 16 of the above-described embodiment, and a detailed description thereof will be omitted. The connector assembly 12A is connected to the substrate 16 in the same manner as the connector assembly 12.

[0077] As shown in FIG. 12, the connector assembly 12A of this modification includes a coaxial connector 20, a member to be fixed 40A, and two fixing members 60. The coaxial connector 20 and the fixing member 60 of this modification are the same as the coaxial connector 20 and the fixing member 60 of the above-described embodiment, and a detailed description thereof will be omitted.

[0078] As shown in FIG. 14, the member to be fixed 40A of this modification has a main portion 401A, a first contact portion 402A, two spring portions 404, and two second contact portions 405. The spring portion 404 and the second contact portion 405 of this modification are the same as the spring portion 404 and the second contact portion 405 of the above-described embodiment, and a detailed description thereof will be omitted.

[0079] As shown in FIG. 14, the main portion 401A of this modification extends in a predetermined plane. Specifically, the main portion 401A extends in a predetermined plane as a whole. The main portion 401A has two protruding portions 4012. The protruding portion 4012 of this modification is the same as the protruding portion 4012 of the above-described embodiment, and a detailed description thereof will be omitted.

[0080] As shown in FIG. 14, the first contact portion 402A of this modified example is composed of one convex portion 403. The convex portion 403 is located at the center in the lateral direction of the member 40A to be fixed. The convex portion 403 protrudes rearward in the front-rear direction from the main portion 401A. As shown in FIG. 12, in the connected state where the connector assembly 12A and the substrate 16 are connected, the convex portion 403 is in contact with the first receiving portion 252. That is, in the connected state, the convex portion 403 of the member 40A to be fixed and the first receiving portion 252 of the flange portion 25 are electrically connected. Referring to FIGS. 12 and 3, in the connected state, the convex portion 403 is located between the two protruding portions 27 in the lateral direction. In the connected state, the convex portion 403 is located at the same position as the contact portion 214 of the center terminal 21 in the lateral direction. In the connected state, the convex portion 403 is located in the vicinity of the contact portion 214 of the center terminal 21.

[0081] As shown in FIG. 14, the member 40A to be fixed has a first distance D1 between the second contact portion 405 and the first contact portion 402A in the front-rear direction in a single state. That is, the member 40A to be fixed has a first distance D1 between the second contact portion 405 and the first contact portion 402A in the front-rear direction in the initial state where the spring portion 404 is not elastically deformed. Referring to FIGS. 10 and 14, the first distance D1 is smaller than the second distance D2. Thereby, in the connected state, with the spring portion 404 elastically deformed, the flange portion 25 is sandwiched between the first contact portion 402A and the second contact portion 405 of the member 40A to be fixed via the first receiving portion 252 and the second receiving portion 254.

[0082] Referring to FIG. 12, in the connected state, the two spring portions 404 press the two second contact portions 405 against the two second receiving portions 254 respectively. More specifically, in the connected state, the spring portion 404 presses the second contact portion 405 against the second receiving portion 254, and the second contact portion 405 receives a reaction force from the second receiving portion 254 due to the above pressing. In the connected state, the first contact portion 402A is pressed against the first receiving portion 252 along the front-rear direction by the above reaction force. Thereby, also in the connector assembly 12A of this modification, the member 40A to be fixed is reliably connected to the outer terminal 24 of the coaxial connector 20. Therefore, when the connector assembly 12A of this modification is connected to the substrate 16, the ground layer 78A of the substrate 16 is electrically connected to the first receiving portion 252 of the flange portion 25 of the outer terminal 24 via the member 40A to be fixed with high reliability. That is, the connector assembly 12A of this modification can stably connect the outer terminal 24 of the coaxial connector 20 of the connector assembly 12A to the ground layer 78A of the substrate 16, and can surely improve the signal reflection characteristics between the substrate 16 and the connector assembly 12A.

[0083] Also, as described above, in the connected state, the first contact portion 402A located near the contact portion 214 of the center terminal 21 of the coaxial connector 20 is pressed against the first receiving portion 252 along the front-rear direction. Thereby, the member 40A to be fixed surely contacts the flange portion 25 in the vicinity of the contact portion 214 of the center terminal 21 of the coaxial connector 20 in the connected state.

[0084] On the other hand, in order to improve the signal reflection characteristics between the substrate 16 and the connector assemblies 12, 12A, it has been found that it is preferable that the members 40, 40A to be fixed contact the flange portion 25 in the vicinity of the center terminal 21 of the coaxial connector 20 in the connected state.

[0085] Turning over, as described above, in the connector assembly 12A of this modified example, in the connected state, it always contacts the flange portion 25 in the vicinity of the contact portion 214 of the center terminal 21 of the coaxial connector 20. Thus, even when the contact force between the first contact portion 402A and the first receiving portion 252 is not large, etc., the connector assembly 12A of this modified example can surely improve the signal reflection characteristics between the substrate 16 and the connector assembly 12A in the connected state.

[0086] (Second Modified Example) Comparing FIG. 15 with FIG. 6, the structure 10B according to the second modified example includes a connector assembly 12B and a substrate 16. The substrate 16 of this modified example is the same as the substrate 16 of the above-described embodiment, and a detailed description thereof is omitted. The connector assembly 12B is connected to the substrate 16 in the same manner as the connector assembly 12.

[0087] As shown in FIG. 15, the connector assembly 12B of this modified example includes a coaxial connector 20, a member to be fixed 40B, and two fixing members 60. The coaxial connector 20 and the fixing member 60 of this modified example are the same as the coaxial connector 20 and the fixing member 60 of the above-described embodiment, and a detailed description thereof is omitted.

[0088] As shown in FIG. 17, the member to be fixed 40B of this modified example has a main portion 401B, a first contact portion 402B, two spring portions 404, and two second contact portions 405. The spring portion 404 and the second contact portion 405 of this modified example are the same as the spring portion 404 and the second contact portion 405 of the above-described embodiment, and a detailed description thereof is omitted.

[0089] As shown in FIG. 17, the main portion 401B of this modified example extends in a predetermined plane. Specifically, the main portion 401B extends in a predetermined plane as a whole. The main portion 401B has two protruding portions 4012. The protruding portion 4012 of this modified example is the same as the protruding portion 4012 of the above-described embodiment, and a detailed description thereof is omitted.

[0090] As shown in FIG. 17, the first contact portion 402B of the second modification includes two convex portions 403B. Note that the present invention is not limited to this, and the first contact portion 402B may include at least one convex portion 403B. Each of the convex portions 403B is located near the center in the lateral direction of the member 40B to be fixed. Each of the convex portions 403B protrudes rearward in the front-rear direction from the main portion 401B. As shown in FIG. 15, in the connected state where the connector assembly 12B is connected to the substrate 16, each of the convex portions 403B is in contact with the first receiving portion 252. That is, in the connected state, the convex portion 403B of the member 40B to be fixed and the first receiving portion 252 of the flange portion 25 are electrically connected. Referring to FIGS. 15 and 3, in the connected state, each of the convex portions 403B is located between the two protruding portions 27 in the lateral direction. In the connected state, the two convex portions 403B 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 convex portions 403B is located near the contact portion 214 of the center terminal 21.

[0091] As shown in FIG. 17, the member 40B to be fixed has a first distance D1 between the second contact portion 405 and the first contact portion 402B in the front-rear direction in a single state. That is, the member 40B to be fixed has a first distance D1 between the second contact portion 405 and the first contact portion 402B in the front-rear direction in an initial state where the spring portion 404 is not elastically deformed. Referring to FIGS. 10 and 17, the first distance D1 is smaller than the second distance D2. Thereby, in the connected state, with the spring portion 404 elastically deformed, the flange portion 25 is sandwiched between the first contact portion 402B and the second contact portion 405 of the member 40B to be fixed via the first receiving portion 252 and the second receiving portion 254.

[0092] Referring to FIG. 15, in the connected state, the two spring portions 404 press the two second contact portions 405 against the two second receiving portions 254 respectively. More specifically, in the connected state, the spring portion 404 presses the second contact portion 405 against the second receiving portion 254, and the second contact portion 405 receives a reaction force from the second receiving portion 254 due to the above pressing. In the connected state, the first contact portion 402B is pressed against the first receiving portion 252 along the front-rear direction by the above reaction force. Thereby, also in the connector assembly 12B of this modification, the member 40B to be fixed is surely connected to the outer terminal 24 of the coaxial connector 20. Therefore, when the connector assembly 12B of this modification is connected to the substrate 16, the ground layer 78A of the substrate 16 is electrically connected to the first receiving portion 252 of the flange portion 25 of the outer terminal 24 via the member 40B with high reliability. That is, the connector assembly 12B of this modification can stably connect the outer terminal 24 of the coaxial connector 20 of the connector assembly 12B to the ground layer 78A of the substrate 16, and can surely improve the signal reflection characteristics between the substrate 16 and the connector assembly 12B.

[0093] Also, as described above, in the connected state, the first contact portion 402B located in the vicinity of the contact portion 214 of the center terminal 21 of the coaxial connector 20 is pressed against the first receiving portion 252 along the front-rear direction. Therefore, the member 40B to be fixed surely contacts the flange portion 25 in the vicinity of the contact portion 214 of the center terminal 21 of the coaxial connector 20 in the connected state. Thereby, similar to the first modification, even when the contact force between the first contact portion 402B and the first receiving portion 252 is not large, etc., the connector assembly 12B of this modification can surely improve the signal reflection characteristics between the substrate 16 and the connector assembly 12B in the connected state.

[0094] (Third Modification) Comparing FIG. 20 with FIG. 8, the structure 10C according to the third modification includes a connector assembly 12C and a substrate 16. The substrate 16 in this modification is the same as the substrate 16 in the above-described embodiment, and a detailed description thereof will be omitted.

[0095] Comparing FIG. 20 with FIG. 8, the connector assembly 12C in this modification includes a coaxial connector 20C and a connection member 40C. The connection member 40C is a single metal plate having a bend. According to this modification, a predetermined portion of the connection member 40C functions as a member to be fixed 41C, and the other two portions of the connection member 40C function as fixing members 46C. That is, the connector assembly 12C includes a coaxial connector 20C different from the coaxial connector 20, a member to be fixed 41C different from the member to be fixed 40, and two fixing members 46C different from the fixing member 60. Each of the member to be fixed 41C and the fixing member 46C in this modification is a part of the connection member 40C. That is, the member to be fixed 41C and the two fixing members 46C are integrally formed with each other.

[0096] As shown in FIG. 21, the coaxial connector 20C in this modification has the same structure as the coaxial connector 20, except that it includes an outer terminal 24C different from the outer terminal 24.

The front conductive member 242C has the same structure as the front conductive member 242, except that it has a protrusion 27C different from the protrusion 27.

[0097] Referring to FIG. 18 in combination with FIG. 5, the coaxial connector 20C is attached to the front end of the coaxial cable 80. Referring to FIG. 21, the coaxial connector 20C includes an outer terminal 24C, a center terminal 21, and an insulating member (not shown). The insulating member insulates the outer terminal 24C and the center terminal 21 from each other. The outer terminal 24C has an end face 26 and two protrusions 27C. The two protrusions 27C are separated from each other in the lateral direction and protrude forward from the end face 26.

[0098] As shown in FIG. 21, press-fitting holes 28C are formed in respective protruding portions 27C. The coaxial connector 20C has the same structure as the coaxial connector 20, except that press-fitting holes 28C are formed instead of screw holes 28. Each of the press-fitting holes 28C of this modification penetrates the protruding portion 27C in the vertical direction. Note that the present invention is not limited to this, and each of the press-fitting holes 28C may be a hole with a ceiling. Each of the press-fitting holes 28C is an oblong hole extending in the front-rear direction. The press-fitting holes 28C are provided at positions corresponding to the through holes 72 of the substrate 16 in the horizontal plane. That is, the two press-fitting holes 28C are separated from each other in the lateral direction and are at the same position as each other in the front-rear direction. The number of the press-fitting holes 28C in this modification is two. However, the present invention is not limited to this. For example, two or more press-fitting holes 28C may be formed in each of the protruding portions 27C.

[0099] As shown in FIG. 22, the center terminal 21 has a contact portion 214. The contact portion 214 is located between the two protruding portions 27C in the lateral direction and extends forward beyond the end face 26. Specifically, the contact portion 214 extends forward and downward in the state before connection in which the connector assembly 12C is not connected to the substrate 16.

[0100] As shown in FIG. 22, the connection member 40C has a member to be fixed 41C, a portion to be pressed 42C, and two press-fitting portions (fixing members) 46C. According to this modification, each of the press-fitting portions 46C functions as a fixing member 46C. In other words, each of the fixing members 46C of this modification is a press-fitting portion 46C.

[0101] As shown in FIG. 22, the fixed member 41C has a main portion 401C, a first contact portion 402, two spring portions 404, and two second contact portions 405. Note that the present invention is not limited to this, and the number of spring portions 404 may be one. That is, the fixed member 41C may have a main portion 401C, a first contact portion 402, at least one spring portion 404, and two second contact portions 405. The first contact portion 402, the spring portion 404, and the second contact portion 405 of this modification are the same as those of the first contact portion 402, the spring portion 404, and the second contact portion 405 in the above-described embodiment, and thus detailed description thereof is omitted.

[0102] As shown in FIG. 22, the main portion 401C of this modification extends within a predetermined plane. Specifically, the main portion 401C extends within a predetermined plane as a whole. Note that the present invention is not limited to this, and as long as a part of the main portion 401C extends within a predetermined plane. That is, the main portion 401C may mainly extend within a predetermined plane.

[0103] As shown in FIG. 22, the main portion 401C has a connecting portion 4011 and two protruding portions 4012. The protruding portion 4012 of this modification is the same as the protruding portion 4012 in the above-described embodiment, and thus detailed description thereof is omitted.

[0104] Referring to FIGS. 20 and 21, the connecting portion 4011 has an upper surface 40U and a lower surface 40L. According to this modification, an intermediate portion in the lateral direction of the upper surface 40U of the connecting portion 4011 mainly functions as a portion to be pressed 42C. As shown in FIG. 22, the two press-fitting portions 46C are respectively located on both sides in the lateral direction of the connecting portion 4011. The connecting portion 4011 connects the two press-fitting portions 46C to each other in the lateral direction. Specifically, each of the press-fitting portions 46C is connected to the connecting portion 4011. As shown in FIG. 20, each of the press-fitting portions 46C extends upward beyond the connecting portion 4011.

[0105] Referring to FIGS. 19 and 21, in the connected state where the connector assembly 12C is connected to the substrate 16, the first contact portion 402 of the member to be fixed 41C is in contact with the first receiving portion 252 of the flange portion 25C. That is, in the connected state, the first contact portion 402 of the member to be fixed 41C and the first receiving portion 252 of the flange portion 25C are electrically connected. Referring to FIGS. 18 and 20, in the connected state, the second contact portion 405 of the member to be fixed 41C is in contact with the second receiving portion 254 of the flange portion 25C. That is, in the connected state, the second contact portion 405 of the member to be fixed 41C and the second receiving portion 254 of the flange portion 25C are electrically connected.

[0106] As shown in FIG. 22, in the single state, the member to be fixed 41C has a first distance D1 between the second contact portion 405 and the first contact portion 402 in the front-rear direction. That is, the member to be fixed 41C has a first distance D1 between the second contact portion 405 and the first contact portion 402 in the front-rear direction in the initial state where the spring portion 404 is not elastically deformed. Referring to FIGS. 10 and 22, the first distance D1 is smaller than the second distance D2. Thereby, in the connected state, with the spring portion 404 elastically deformed, the flange portion 25C is sandwiched between the first contact portion 402 and the second contact portion 405 of the member to be fixed 41C via the first receiving portion 252 and the second receiving portion 254.

[0107] Referring to FIGS. 18, 19 and 20, in the connected state, the two spring portions 404 press the two second contact portions 405 against the two second receiving portions 254 respectively. More specifically, in the connected state, the spring portion 404 presses the second contact portion 405 against the second receiving portion 254, and the second contact portion 405 receives a reaction force from the second receiving portion 254 due to the above pressing. Referring to FIGS. 19 and 21, in the connected state, the first contact portion 402 is pressed against the first receiving portion 252 along the front-rear direction by the above reaction force. Thereby, also in the connector assembly 12C of this modification example, the member 41C to be fixed is surely connected to the outer terminal 24C of the coaxial connector 20C. Therefore, when the connector assembly 12C of this modification example is connected to the substrate 16, the ground layer 78A of the substrate 16 is electrically connected to the first receiving portion 252 of the flange portion 25C of the outer terminal 24C via the member 41C to be fixed with high reliability. That is, the connector assembly 12C of this modification example can stably connect the outer terminal 24C to the ground layer 78A of the substrate 16, and can surely improve the signal reflection characteristics between the substrate 16 and the connector assembly 12C.

[0108] Referring to FIGS. 18 and 20, the size of each of the press-fitting holes 28C in the lateral direction is smaller than the size of the press-fitted portion 46C in the lateral direction. Each of the press-fitted portions 46C passes through the through hole 72 of the substrate 16 and is press-fitted into the press-fitting hole 28C in the connected state. As shown in FIG. 20, a hole portion 48C is formed in each of the press-fitted portions 46C. Each of the hole portions 48C extends in the vertical direction and penetrates the press-fitted portion 46C in the front-rear direction. Each of the press-fitted portions 46C in which the hole portion 48C is formed elastically deforms so as to be partially compressed in the lateral direction when receiving a force along the lateral direction. A force directed outward in the lateral direction is generated in each of the elastically deformed press-fitted portions 46C due to the restoring force.

[0109] Note that, as described above, each of the press-fitting holes 28C is an oval hole extending in the front-rear direction. As a result, there is a slight degree of freedom in the front-rear direction for the press-fitting position when press-fitting the press-fitted portion 46C into the press-fitting hole 28C. This enables each of the press-fitted portions 46C to be accurately press-fitted into the press-fitting hole 28C so that the first contact portion 402 of the member to be fixed 41C and the first receiving portion 252 of the flange portion 25C come into reliable contact without creating a gap in the front-rear direction.

[0110] Comparing FIG. 18 with FIG. 1, the connector assembly 12C is connected to the substrate 16 by a press-fitting connection method using the press-fitted portion 46C, rather than the screwing connection method using the screw 60 in the connector assembly 12.

[0111] Specifically, when connecting the connector assembly 12C to the substrate 16, each of the press-fitted portions 46C passes through the through holes 72 of the substrate 16 and is inserted into the press-fitting holes 28C of the coaxial connector 20C. Here, as described above, the size of each of the press-fitting holes 28C in the lateral direction is smaller than the size of the press-fitted portion 46C in the lateral direction. Therefore, each of the press-fitted portions 46C is inserted into the press-fitting hole 28C while being compressed in the lateral direction. The press-fitted portion 46C inserted into each of the press-fitting holes 28C is pressed against the inner wall surface of the press-fitting hole 28C by the restoring force. As a result, the connecting member 40C is fixed to the coaxial connector 20C, and the connector assembly 12C is connected to the substrate 16.

[0112] Referring to FIG. 19, the member 41C to be fixed of the connecting member 40C is located below in the vertical direction of the substrate 16 in the connected state where the connector assembly 12C is connected to the substrate 16. Referring to FIGS. 18 and 20, the two fixing members 46C of the connecting member 40C, in the connected state, press the portion 42C to be pressed of the member 41C to be fixed against the lower surface 70L of the portion of the substrate 16 where the signal line 74 is formed, and pass through the two through holes 72 of the substrate 16 to be respectively fixed to the two protruding portions 27C of the outer terminal 24C. Thereby, the contact portion 214 (see FIG. 21) of the center terminal 21 is pressed against the signal line 74 of the substrate 16 to make contact, and the contact portion 214 and the signal line 74 are electrically connected. Note that the present invention is not limited to this, and the contact portion 214 and the signal line 74 may be connected by soldering.

[0113] According to this modification, each of the press-fitting portions 46C passes through the through hole 72 of the substrate 16 and is press-fitted into the press-fitting hole 28C in the connected state. The connection method by press-fitting can be easily executed in a shorter time compared to the connection method by screwing.

[0114] (Fourth Modification) Comparing FIG. 24 with FIG. 2, the structure 10D according to the fourth modification includes a connector assembly 12D and a substrate 16. The substrate 16 of this modification is the same as the substrate 16 of the above-described embodiment, and a detailed description thereof is omitted. The connector assembly 12D is connected to the substrate 16 in the same manner as the connector assembly 12.

[0117] As shown in FIG. 26, the outer terminal 24D of this modified example includes a front conductive member 242D and a rear conductive member 244. The rear conductive member 244 of this modified example is the same as the rear conductive member 244 of the above-described embodiment, and a detailed description thereof will be omitted.

[0118] As shown in FIG. 25, the outer terminal 24D of this modified example has a flange portion 25D and two protruding portions 27. The protruding portion 27 of this modified example is the same as the protruding portion 27 of the above-described embodiment, and a detailed description thereof will be omitted.

[0119] Referring to FIG. 26, the flange portion 25D of this modified example has a first receiving portion 252D and two second receiving portions 254D.

[0120] As shown in FIG. 25, the first receiving portion 252D faces forward in the front-rear direction that is orthogonal to both the vertical direction and the horizontal direction. The first receiving portion 252D is located near the center of the flange portion 25D in the vertical direction. The first receiving portion 252D is located at the center of the flange portion 25D in the horizontal direction.

[0121] Referring to FIG. 26, each of the two second receiving portions 254D faces rearward in the front-rear direction. Note that the present invention is not limited thereto, and the second receiving portion 254D may face rearward in the front-rear direction and outward in the horizontal direction. That is, each of the two second receiving portions 254D only needs to face at least rearward in the front-rear direction. The second receiving portion 254D is located at both ends of the flange portion 25D in the horizontal direction.

[0122] As shown in FIG. 26, the first receiving portion 252D is located forward in the front-rear direction with respect to the second receiving portion 254D. Note that the present invention is not limited to this. As long as the first receiving portion 252D faces forward and the second receiving portion 254D faces at least rearward, the first receiving portion 252D may be located rearward in the front-rear direction with respect to the second receiving portion 254D. When the first receiving portion 252D and the second receiving portion 254D are configured as in this modification example, it is more preferable because an increase in the size of the flange portion 25D in the front-rear direction can be avoided. The flange portion 25D has a second distance D2 between the first receiving portion 252D and the second receiving portion 254D in the front-rear direction.

[0123] Referring to FIG. 26, the flange portion 25D of this modification example has a flat surface portion 257, an end surface 26D, a guiding portion 256D, two first locking portions 258, and two second locking portions 259.

[0124] As shown in FIG. 26, the flat surface portion 257 of this modification example is a plane parallel to the YZ plane. The flat surface portion 257 defines the lower end of the flange portion 25D in the up-down direction.

[0125] As shown in FIG. 26, the end surface 26D of this modification example is a plane parallel to the YZ plane. The first receiving portion 252D is a part of the end surface 26D of the flange portion 25D. Each of the two protruding portions 27 protrudes forward in the front-rear direction from the end surface 26D. The contact portion 214 of the center terminal 21 is located forward of the end surface 26D. The contact portion 214 extends forward in the front-rear direction beyond the end surface 26D.

[0126] As shown in FIG. 26, the guiding portion 256D of this modification example is obliquely intersecting both the front-rear direction and the up-down direction. The guiding portion 256D is located between the flat surface portion 257 and the first receiving portion 252D in the up-down direction. The guiding portion 256D is located above the flat surface portion 257 in the up-down direction. The guiding portion 256D is located below the first receiving portion 252D in the up-down direction. As shown in FIG. 25, the guiding portion 256D is located below the center hole 29 in the up-down direction.

[0127] Referring to FIG. 26, the first stopper portion 258 of this modified example corresponds to the second receiving portion 254D respectively. Each of the first stopper portions 258 is located below the corresponding second receiving portion 254D in the vertical direction. Each of the first stopper portions 258 faces upward in the vertical direction. Each of the first stopper portions 258 is a surface orthogonal to the vertical direction. The first stopper portion 258 is located below the second stopper portion 259 in the vertical direction.

[0128] Referring to FIG. 26, the second stopper portion 259 of this modified example corresponds to the second receiving portion 254D respectively. Each of the second stopper portions 259 is located above the corresponding second receiving portion 254D in the vertical direction. Each of the second stopper portions 259 faces downward in the vertical direction. Each of the second stopper portions 259 is a surface orthogonal to the vertical direction. The second stopper portion 259 is located above the first stopper portion 258 in the vertical direction.

[0129] As shown in FIGS. 23 and 25, the member 40D to be fixed has a main portion 401B, a first contact portion 402B, two spring portions 404, two second contact portions 405, two first stopper portions 408, and two second stopper portions 409. The main portion 401B, the first contact portion 402B, the spring portion 404, and the second contact portion 405 of this modified example are the same as those of the main portion 401B, the first contact portion 402B, the spring portion 404, and the second contact portion 405 of the member 40B to be fixed in the second modified example, and detailed description thereof is omitted. The second contact portion 405 corresponds to the first stopper portion 258 respectively. The second contact portion 405 corresponds to the second stopper portion 259 respectively.

[0130] Referring to FIGS. 24 and 25, when attaching the member 40D to be fixed to the coaxial connector 20D, the attracting portion 256D guides the first contact portion 402B to the first receiving portion 252D.

[0131] As shown in FIG. 24, in the connected state, each of the convex portions 403B of the first contact portion 402B is in contact with the first receiving portion 252D. That is, in the connected state, the convex portion 403B and the first receiving portion 252D of the flange portion 25D are electrically connected. Referring to FIGS. 24 and 25, in the connected state, each of the convex portions 403B is located between the two protrusions 27 in the lateral direction. In the connected state, the two convex portions 403B 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 convex portions 403B is located in the vicinity of the contact portion 214 of the center terminal 21.

[0132] Referring to FIG. 25, the member 40D to be fixed has a first distance between the second contact portion 405 and the first contact portion 402B in the front-rear direction in a single state. That is, the member 40D to be fixed has a first distance between the second contact portion 405 and the first contact portion 402B in the front-rear direction in an initial state where the spring portion 404 is not elastically deformed. Referring to FIGS. 25 and 26, the first distance is smaller than the second distance D2. Thereby, referring to FIGS. 23 and 24, in the connected state, with the spring portion 404 elastically deformed, the flange portion 25D is sandwiched between the first contact portion 402B and the second contact portion 405 of the member 40D to be fixed via the first receiving portion 252D and the second receiving portion 254D.

[0133] Referring to FIG. 23, in the connected state, the two spring portions 404 press the two second contact portions 405 against the two second receiving portions 254D respectively. More specifically, in the connected state, the spring portion 404 presses the second contact portion 405 against the second receiving portion 254D, and the second contact portion 405 receives a reaction force from the second receiving portion 254D due to the above pressing. Referring to FIG. 24, in the connected state, the convex portion 403B of the first contact portion 402B is pressed against the first receiving portion 252D along the front-rear direction by the above reaction force. Thus, also in the connector assembly 12D of this modified example, the member 40D to be fixed is surely connected to the outer terminal 24D of the coaxial connector 20D. Therefore, when the connector assembly 12D of this modified example is connected to the substrate 16, the ground layer 78A of the substrate 16 is electrically connected to the first receiving portion 252D of the flange portion 25D of the outer terminal 24D via the member 40D to be fixed with high reliability. That is, the connector assembly 12D of this modified example can stably connect the outer terminal 24D of the coaxial connector 20D of the connector assembly 12D to the ground layer 78A of the substrate 16, and can surely improve the signal reflection characteristics between the substrate 16 and the connector assembly 12D.

[0134] Also, as described above, in the connected state, the first contact portion 402B located in the vicinity of the contact portion 214 of the center terminal 21 of the coaxial connector 20D is pressed against the first receiving portion 252D along the front-rear direction. Thus, in the connected state, the member 40D to be fixed surely contacts the flange portion 25D in the vicinity of the contact portion 214 of the center terminal 21 of the coaxial connector 20D. Thus, similar to the second modified example, even when the contact force between the first contact portion 402B and the first receiving portion 252D is not large, etc., the connector assembly 12D of this modified example can surely improve the signal reflection characteristics between the substrate 16 and the connector assembly 12D in the connected state.

[0135] As shown in FIG. 25, the first engaged portions 408 of this modified example respectively correspond to the spring portions 404. Each of the first engaged portions 408 is located at the inner end in the width direction of the second portion 4042 of the corresponding spring portion 404. The first engaged portions 408 face downward in the vertical direction.

[0136] Referring to FIG. 23, the second engaged portions 409 of this modified example respectively correspond to the spring portions 404. Each of the second engaged portions 409 is located at the inner end in the width direction of the second portion 4042 of the corresponding spring portion 404. The second engaged portions 409 face upward in the vertical direction.

[0137] Referring to FIGS. 24 and 25, in the connected state, the two fixing members 60 press the member 40D to be fixed against the ground layer 78A of the substrate 16 to make the predetermined plane orthogonal to the vertical direction, and pass through the two through holes 72 of the substrate 16 and are respectively fixed to the two protrusions 27 of the outer terminal 24D.

[0138] Referring to FIG. 27, the member 40D to be fixed in this modified example can be in a temporarily assembled state temporarily assembled to the coaxial connector 20D. Specifically, referring to FIGS. 25 and 27, while the second contact portion 405 is located between the corresponding first stop portion 258 and the corresponding second stop portion 259, and the convex portion 403B contacts the guiding portion 256D, the spring portion 404 is elastically deformed and the member 40D to be fixed is attached to the coaxial connector 20D. Thereby, the coaxial connector 20D and the member 40D to be fixed are in the temporarily assembled state shown in FIG. 27.

[0139] In this provisional assembly state, the first locking portion 408 of the member 40D to be fixed is in contact with the first locking portion 258 of the coaxial connector 20D, and the convex portion 403B of the member 40D to be fixed is in contact with the attracting portion 256D. Also, in this provisional assembly state, even if the coaxial connector 20D is turned upside down, the second locking portion 409 (see FIG. 23) of the member 40D to be fixed comes into contact with the second locking portion 259 of the coaxial connector 20D, and the convex portion 403B of the member 40D to be fixed comes into contact with the flat portion 257 of the flange portion 25D. Therefore, the member 40D to be fixed does not fall off from the coaxial connector 20D. From these facts, the member 40D to be fixed and the coaxial connector 20D can be transported in the provisional assembly state as it is.

[0140] (Fifth Modification Example) As shown in FIG. 28, the structure 10E according to the first modification example includes a connector assembly 12E and a substrate 16.

The second receiving portions 254E are located at both ends of the flange portion 25E in the lateral direction.

[0147] As shown in FIG. 29, the first receiving portion 252 is located forward of the second receiving portion 254E in the front-rear direction.

[0157] As shown in FIG. 33, the second part 4042E of this modification extends in a direction intersecting the front-rear direction from the first part 4041E. That is, the second part 4042E extends inward in the lateral direction orthogonal to the front-rear direction from the first part 4041E.

[0158] As shown in FIG. 33, the support part 406 of this modification extends from the main part 401E. Specifically, the support part 406 extends rearward in the front-rear direction from the left end of the main part 401E, and then bends and extends inward in the width direction.

[0159] As shown in FIG. 33, the two second contact parts 405E of this modification are located apart from each other in the lateral direction. As shown in FIG. 29, in the connected state, the second contact parts 405E are in contact with the second receiving parts 254E respectively. In the connected state, the second contact parts 405E of the metal fixed member 40E are electrically connected to the second receiving parts 254E of the metal flange part 25E. Note that the present invention is not limited to this, and in the connected state, the second contact parts 405E and the second receiving parts 254E may not be electrically connected.

[0160] As shown in FIG. 33, the two second contact parts 405E include a second main contact part 4051 and a second sub-contact part 4052.

[0161] As shown in FIG. 33, the second main contact part 4051 is located near the inner end in the lateral direction of the second part 4042E. The second main contact part 4051 is located to the right in the left-right direction of the second sub-contact part 4052. The spring part 404E supports the second main contact part 4051. Thereby, the second main contact part 4051 can be displaced within a predetermined plane. Referring to FIG. 29, when the fixed member 40E is attached to the coaxial connector 20E, the guiding part 256E guides the second main contact part 4051 to the second main receiving part 2541. In the connected state, the second main contact part 4051 is in contact with the second main receiving part 2541.

[0162] As shown in FIG. 33, the second secondary contact portion 4052 is located near the lateral inner end of the support portion 406. The support portion 406 supports the second secondary contact portion 4052. The second secondary contact portion 4052 is located to the left in the left-right direction of the second main contact portion 4051. The second secondary contact portion 4052 is located near the left end in the left-right direction of the member 40E to be fixed. As shown in FIG. 29, in the connected state, the second secondary contact portion 4052 contacts the second secondary receiving portion 2542. Referring to FIGS. 32 and 33, the distance between the second secondary contact portion 4052 and the first contact portion 402E in the front-rear direction of the member 40E to be fixed in the single state is substantially equal to the second distance D2.

[0163] As shown in FIG. 33, the member 40E to be fixed has a first distance D1 between the second main contact portion 4051 and the first contact portion 402E in the front-rear direction in the single state. That is, the member 40E to be fixed has a first distance D1 between the second contact portion 405E and the first contact portion 402E in the front-rear direction in the single state. The member 40E to be fixed has a first distance D1 between the second main contact portion 4051 and the first contact portion 402E in the front-rear direction in the initial state where the spring portion 404E is not elastically deformed. Referring to FIGS. 32 and 33, the first distance D1 is smaller than the second distance D2. Accordingly, in the connected state, with the spring portion 404E elastically deformed, the flange portion 25E is sandwiched between the first contact portion 402E and the second main contact portion 4051 of the member 40E to be fixed via the first receiving portion 252 and the second main receiving portion 2541.

[0164] Referring to FIG. 29, in the connected state, the spring portion 404E presses the second main contact portion 4051 against the second main receiving portion 2541, and the second main contact portion 4051 receives a reaction force from the second main receiving portion 2541 due to the pressing. In the connected state, the first contact portion 402E is pressed against the first receiving portion 252 along the front-rear direction by the reaction force. Thus, also in the connector assembly 12E of this modified example, the member to be fixed 40E is surely connected to the outer terminal 24E of the coaxial connector 20E. Therefore, when the connector assembly 12E of this modified example is connected to the substrate 16, the ground layer 78A of the substrate 16 is electrically connected to the first receiving portion 252 of the flange portion 25E of the outer terminal 24E via the member to be fixed 40E with high reliability. That is, the connector assembly 12E of this modified example can stably connect the outer terminal 24E of the coaxial connector 20E of the connector assembly 12E to the ground layer 78A of the substrate 16, and can surely improve the signal reflection characteristics between the substrate 16 and the connector assembly 12E.

[0165] Also, as described above, in the connected state, the first contact portion 402E located in the vicinity of the contact portion 214 of the center terminal 21 of the coaxial connector 20E is pressed against the first receiving portion 252 along the front-rear direction. Thereby, the member to be fixed 40E surely comes into contact with the flange portion 25E in the vicinity of the contact portion 214 of the center terminal 21 of the coaxial connector 20E in the connected state. Thus, similar to the first modified example, even when the contact force between the first contact portion 402E and the first receiving portion 252 is not large, the connector assembly 12E of this modified example can surely improve the signal reflection characteristics between the substrate 16 and the connector assembly 12E in the connected state.

[0166] As shown in FIG. 33, the member to be fixed 40E has a portion to be pressed 42E. As will be described later, the portion to be pressed 42E is a portion that is pressed against the substrate 16 in the connected state (see FIG. 29). According to this modified example, the intermediate portion in the lateral direction of the upper surface 40U mainly functions as the portion to be pressed 42E.

[0167] Referring to FIG. 29, in the connector assembly 12E of this modification, the second auxiliary receiving portion 2542 is located at the left end of the flange portion 25E, and the second auxiliary contact portion 4052 supported by the support portion 406 is located near the left end of the member 40E to be fixed. On the other hand, when one of the fixing members 60, which is the right screw 60, is screwed into the screw hole 28 (see FIG. 30), a force that rotates the member 40E to be fixed clockwise as viewed from below acts on the member 40E to be fixed. However, in the connector assembly 12E of this modification, the second auxiliary receiving portion 2542 and the second auxiliary contact portion 4052 are arranged as described above. Thus, when one of the fixing members 60 is screwed into the screw hole 28, the second auxiliary receiving portion 2542 with which the second auxiliary contact portion 4052 is in contact receives the above force, so that the above rotation of the member 40E to be fixed with respect to the flange portion 25E can be suppressed.

[0168] Although the embodiments and various modifications have been described above, the above-described embodiments and modifications can be further variously modified and can be variously combined.
