Description

Technical Field

[0001] The present invention relates to a connector assembly configured to be connected to a substrate. Background Art

[0002] For example, JPB 6853655 (Patent Document 1) discloses a connector assembly configured to be connected to a substrate.

[0003] Reference Figure 26 and Figure 27 Patent Document 1 discloses a substrate-connector connection structure 900 having a substrate 950 and a connector 910, or connector assembly 910. Specifically, connector assembly 910 is connected to substrate 950. Substrate 950 has a signal pattern 952, or signal line 952, a first ground layer 954, and a plating layer 956. Specifically, plating layer 956 is located directly below signal line 952 and is formed in an area including the end surface of first ground layer 954. Connector assembly 910 includes a coaxial connector 920 and two screws 930, or fixing members 930. Coaxial connector 920 has a center conductor 922, or center terminal 922, and an outer conductor 924, or outer terminal 924. When connector assembly 910 is connected to substrate 950, outer terminal 924 contacts plating layer 956, which is electrically connected to first ground layer 954. With this structure, substrate-connector connection structure 900 of Patent Document 1 is configured to reduce reflection characteristics of signals propagating between substrate 950 and connector assembly 910.

[0004] In the substrate-connector connection structure 900 of Patent Document 1, when the connector assembly 910 is connected to the substrate 950, it is difficult for the external terminal 924 of the coaxial connector 920 to be stably connected to the plating layer 956 of the substrate 950. Therefore, the substrate-connector connection structure 900 of Patent Document 1 may not be able to form a reliable electrical connection between the external terminal 924 and the first ground layer 954. Summary of the Invention

[0005] An object of the present invention is to provide a connector assembly that enables an external terminal of a coaxial connector of the connector assembly to be stably connected to a ground layer of a substrate.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] One aspect of the present invention provides a connector assembly configured to connect to a substrate. The substrate is formed with two through-holes. Each through-hole passes through the substrate in the vertical direction. The substrate has an upper surface and a lower surface in the vertical direction. A signal line is formed on the upper surface of the substrate. The signal line is located between the two through-holes in a lateral direction perpendicular to the vertical direction. A ground layer is formed on the lower surface of the substrate. The connector assembly includes a coaxial connector, a fixing member, and two screws. The coaxial connector is configured to connect to the distal end of a coaxial cable. The coaxial connector includes an outer terminal and a center terminal. The outer terminal has a flange portion and two protrusions. The flange portion has a first receiving portion. The first receiving portion faces forward in a front-to-back direction perpendicular to the vertical and lateral directions. The two protrusions are separated from each other in the lateral direction. Each protrusion extends forward from the flange portion in the front-to-back direction. Each protrusion has a screw hole. Each protrusion is provided with a second receiving portion. The second receiving portion faces at least rearward in the front-to-back direction. The fixing member is made of metal. When the connector assembly is connected to the substrate, a portion of the fixing member is located below the substrate in the vertical direction. When connected, the ground layer of the substrate is electrically connected to the first receiving portion of the flange portion via a fixed member. The fixed member has two fixing holes. Each fixing hole extends vertically through the fixed member. The fixed member includes a spring portion, a first contact portion, and two second contact portions. The spring portion is elastically deformable and supports the first contact portion and the two second contact portions. The first contact portion is located behind each of the two second contact portions in the front-to-back direction. The two second contact portions are spaced apart from each other in the transverse direction. The fixed member has a distance between the first contact portion and each of the two second contact portions in the front-to-back direction. This distance is variable due to the elastic deformation of the spring portion. In the connected state, the elastic deformation of the spring portion causes the first contact portion to be pressed against the first receiving portion, while the two second contact portions are pressed against the second receiving portions of the two protrusions, respectively. In the connected state, screws are screwed through the fixing holes and through-holes into the screw holes of the protrusions, thereby securing each screw to each protrusion and simultaneously pressing the fixed member against the ground layer of the substrate.

[0008] The connector assembly of the present invention is configured such that, when the connector assembly is connected to a substrate, the elastic deformation of the spring portion of the fixed member causes the first contact portion of the fixed member to press against the first receiving portion of the flange portion of the external terminal of the coaxial connector, while the two second contact portions of the fixed member press against the second receiving portions of the two protrusions of the external terminal of the coaxial connector, respectively. Therefore, the connector assembly of the present invention is configured such that the fixed member is securely connected to the external terminal of the coaxial connector. Therefore, when the connector assembly of the present invention is connected to the substrate, the ground layer of the substrate is electrically connected to the first receiving portion of the flange portion of the external terminal via the fixed member in a highly reliable manner. In other words, the connector assembly of the present invention enables the external terminal of the coaxial connector of the connector assembly to be stably connected to the ground layer of the substrate.

[0036] Reference Figure 2 The structure 10 of the embodiment of the present invention includes a connector assembly 12 and a base plate 16. The base plate 16 extends along a horizontal plane. The connector assembly 12 is configured to be connected to the base plate 16. In detail, the connector assembly 12 is configured to be connected to the rear end portion of the base plate 16 in a front-to-rear direction parallel to the horizontal plane. Figures 1 to 7 The connector assembly 12 in FIG. 1 is in a connected state where the connector assembly 12 is connected to the substrate 16. In contrast, Figure 8 and Figure 9 The connector assembly 12 is in a pre-connected state in which the connector assembly 12 has not yet been connected to the substrate 16.

[0037] In this embodiment, the horizontal plane is the XY plane. The front-to-back direction in this embodiment is the X direction. In this embodiment, "forward" refers to the positive X direction, and "rearward" refers to the negative X direction. Terms such as the horizontal plane and the front-to-back direction do not indicate absolute positional relationships relative to the ground. Instead, they simply indicate relative positional relationships, given that the substrate 16 extends on the horizontal plane and the connector assembly 12 is located behind the substrate 16.

[0038] Reference Figure 8 and Figure 9 There is no particular limitation on the substrate 16. The substrate 16 may be a flexible board or a rigid board.

[0039] like Figure 8 and Figure 9 As shown, substrate 16 has an upper surface 70U and a lower surface 70L in a vertical direction perpendicular to a horizontal plane. Upper surface 70U and lower surface 70L are located at the upper and lower ends of base 70, respectively. In this embodiment, the vertical direction is the Z direction. In this embodiment, "upward" refers to the positive Z direction, and "downward" refers to the negative Z direction.

[0040] like Figure 8As shown, the substrate 16 is formed with two through holes 72. Each through hole 72 passes through the substrate 16 in the up-down direction. Each through hole 72 has a circular shape in the horizontal plane. When the connector assembly 12 is screwed onto the substrate 16 as described below, the through holes 72 formed in this way are used. The two through holes 72 are separated from each other in a lateral direction perpendicular to the front-to-back direction and the up-to-down direction, and are located at the same position as each other in the front-to-back direction. The lateral direction of this embodiment is the Y direction. In addition, the lateral direction is also referred to as the left-right direction. In this embodiment, "rightward" refers to the positive Y direction, and "leftward" refers to the negative Y direction.

[0041] The through holes 72 of this embodiment are formed as described above. However, the present invention is not limited thereto. For example, the shape of each through hole 72 is not particularly limited. Furthermore, the number of through holes 72 may be three or more. In this case, two through holes 72 may be separated from each other in the lateral direction and may be located at the same position relative to each other in the front-to-back direction.

[0042] like Figure 8 As shown, a signal line 74 as a conductive pattern is formed on the upper surface 70U of the substrate 16. The signal line 74 extends in the front-to-back direction and is located between the two through-holes 72 in the lateral direction.

[0043] like Figure 9 As shown, a ground layer 78A is formed on the lower surface 70L of the substrate 16 . The ground layer 78A is a conductive pattern and covers the entire lower surface 70L.

[0044] Reference Figure 3 , the signal line 74 of this embodiment is connected to an antenna formed on the front end portion of the substrate 16, not shown. In this case, the connector component 12 transmits a signal to the antenna through the signal line 74 in the connected state. The signal thus transmitted is sent outward from the antenna. On the other hand, the signal received by the antenna is transmitted to the connector component 12 through the signal line 74. The structure 10 of this embodiment is used, for example, as described above. In other words, the structure 10 of this embodiment is an antenna device. However, the use of the structure 10 of the present invention is not specifically limited.

[0045] The substrate 16 of the present embodiment has the above-described configuration. However, the configuration of the substrate 16 may be modified according to the use of the structure 10. For example, the ground layer 78A may be partially formed on the lower surface 70L.

[0046] Reference Figure 9 The connector assembly 12 of this embodiment includes a coaxial connector 20, a fixed member 40, and two screws 60. The connector assembly 12 of this embodiment includes only the aforementioned components. However, the present invention is not limited thereto. For example, the connector assembly 12 may include another component in addition to the aforementioned components.

[0047] Hereinafter, the coaxial connector 20 , the fixed member 40 , and the screw 60 of the present embodiment will be described in sequence.

[0048] Reference Figure 6 The coaxial connector 20 of this embodiment is configured to be connected to the distal end of the coaxial cable 80. Specifically, the coaxial connector 20 is configured to be connected to the front end of the coaxial cable 80. The coaxial connector 20 of this embodiment is a so-called subminiature male (SMA) connector. However, the present invention is not limited thereto and is applicable to various coaxial connectors 20.

[0049] Reference Figure 6 , the coaxial cable 80 shown in dotted lines is a typical coaxial cable and includes a center conductor (not shown) made of a conductor, an inner insulator (not shown) made of an insulator and covering the center conductor, an outer conductor (not shown) made of a conductor and covering the inner insulator, and a sheath 88 made of an insulator and covering the outer conductor. The number of center conductors in this embodiment is one. The structure of the coaxial cable 80 is not particularly limited as long as the number of center conductors is one. For example, the outer conductor can be a braid formed of thin metal wires or can be made of metal foil. For example, the coaxial cable 80 can be connected to the rear end of the coaxial connector 20 via a matching connector (not shown) attached to the coaxial cable 80.

[0050] Reference Figure 9 The coaxial connector 20 of this embodiment includes a center terminal 21 made of metal and an outer terminal 24 made of metal.

[0051] like Figure 3 As shown, the center terminal 21 of this embodiment extends in the front-to-back direction and has a contact portion 214. The contact portion 214 defines the front end of the center terminal 21 in the front-to-back direction. Figure 3 and Figure 6 When the coaxial connector 20 is connected 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 connected to each other transmit signals to each other.

[0052] like Figure 12 As shown, the external 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 contacts the rear conductive member 244. The external terminal 24 of this embodiment is composed of the above two members. However, the present invention is not limited to this. For example, the front conductive member 242 and the rear conductive member 244 can be members formed integrally with each other.

[0053] Reference Figure 6When the coaxial connector 20 is attached to the coaxial cable 80, the external terminal 24 is connected to the external conductor of the coaxial cable 80. Specifically, the rear conductive member 244 of the external terminal 24 is configured to be electrically connected to the external conductor. The external terminal 24 and the external conductor connected to each other have the same ground potential.

[0054] like Figure 9 As shown, the external terminal 24 has a flange portion 25 and two protruding portions 27 .

[0055] like Figure 9 As shown, the flange portion 25 of this embodiment has a first receiving portion 252 .

[0056] like Figure 9 As shown, the first receiving portion 252 faces forward in the front-rear direction perpendicular to the up-down direction and the lateral direction. The first receiving portion 252 is located around the middle of the flange portion 25 in the up-down direction. The first receiving portion 252 is located in the middle of the flange portion 25 in the lateral direction. Figure 2 and Figure 9 In the connected state, the ground layer 78A of the substrate 16 is electrically connected to the first receiving portion 252 of the flange portion 25 via the fixed member 40 .

[0057] like Figure 9 As shown, the flange portion 25 further has an end surface 26. In this embodiment, the end surface 26 is a plane parallel to the YZ plane. The first receiving portion 252 is a portion of the end surface 26 of the flange portion 25. The contact portion 214 of the center terminal 21 is located in front of the end surface 26. The contact portion 214 extends forward beyond the end surface 26 in the front-to-back direction.

[0058] like Figure 9 As shown, the two protrusions 27 of this embodiment are separated from each other in the transverse direction. The contact portion 214 is located between the two protrusions 27 in the transverse direction. Each protrusion 27 extends forward from the flange portion 25 in the front-to-rear direction. Each protrusion 27 protrudes forward from the end surface 26. The two protrusions 27 of this embodiment have mirror-symmetrical shapes relative to a plane perpendicular to the transverse direction. The two protrusions 27 arranged in this way are located at the same position as each other in the vertical direction. Each protrusion 27 has an upper surface 27U and a lower surface 27L in the vertical direction. The upper surface 27U and the lower surface 27L are flat surfaces parallel to the horizontal plane. The upper surface 27U defines the upper end of the protrusion 27 in the vertical direction. The lower surface 27L defines the lower end of the protrusion 27 in the vertical direction.

[0059] like Figure 9As shown, each protrusion 27 of the present embodiment is formed with a screw hole 28. Each screw hole 28 of the present embodiment passes through the protrusion 27 in the up-down direction. Each screw hole 28 is arranged at a position corresponding to the through hole 72 of the substrate 16 on the horizontal plane. Specifically, the two screw holes 28 are separated from each other in the lateral direction and are located at the same position as each other in the front-to-back direction. The number of screw holes 28 in the present embodiment is two. However, the present invention is not limited to this. For example, each protrusion 27 may be formed with two or more screw holes 28. Each screw hole 28 may be a hole with a cap.

[0060] like Figure 10 As shown, each protrusion 27 of this embodiment is formed with a second receiving portion 272 .

[0061] like Figure 8 As shown, the second receiving portion 272 of this embodiment faces rearward in the front-to-back direction. However, the present invention is not limited thereto. Specifically, the second receiving portion 272 should at least face rearward in the front-to-back direction. Figure 10 As shown, the second receiving portion 272 is positioned around the outer end of the protruding portion 27 in the lateral direction. The second receiving portion 272 is located in front of the flange portion 25 in the front-to-rear direction. Figure 10 and Figure 11 , the second receiving portion 272 is located in front of the first receiving portion 252 in the front-to-back direction. Figure 11 As shown, the second receiving portion 272 is located in front of the contact portion 214 along the front-to-back direction. Figure 12 As shown, the coaxial connector 20 has a first distance D1 between the first receiving portion 252 and any one of the second receiving portions 272 in the front-to-rear direction.

[0062] like Figure 12 As shown, each protrusion 27 is provided with a guide portion 273. However, the present invention is not limited thereto, and the protrusion 27 may not be provided with the guide portion 273.

[0063] like Figure 12 As shown, the guide portion 273 is located below the second receiving portion 272 in the vertical direction. The guide portion 273 intersects the front-to-back direction. More specifically, the guide portion 273 is inclined relative to the front-to-back direction. The guide portion 273 intersects the vertical direction. More specifically, the guide portion 273 is inclined relative to the vertical direction. Specifically, the guide portion 273 extends upward and rearward.

[0064] like Figure 12 As shown, each protrusion 27 is provided with a third receiving portion 276. However, the present invention is not limited thereto, and the protrusion 27 may not be provided with the third receiving portion 276.

[0065] like Figure 8As shown, the third receiving portion 276 of this embodiment faces outward in the transverse direction. The third receiving portion 276 is a plane perpendicular to the transverse direction. In each protrusion 27, the third receiving portion 276 is located inside the second receiving portion 272 in the transverse direction. In each protrusion 27, the third receiving portion 276 is located above the second receiving portion 272 in the up-down direction. Figure 9 As shown, the third receiving portion 276 is located in front of the first receiving portion 252 in the front-to-back direction. The third receiving portion 276 is located outside the center terminal 21 in the lateral direction. The third receiving portion 276 is located above the center terminal 21 in the vertical direction. The third receiving portion 276 is located above the first receiving portion 252 in the vertical direction.

[0066] like Figure 9 As shown, each protrusion 27 has a first portion 2701 and a second portion 2702 .

[0067] like Figure 10 As shown, the first portion 2701 of this embodiment extends forward from the flange portion 25 in the front-to-rear direction. The screw hole 28 is provided at the first portion 2701. The third receiving portion 276 is provided on the first portion 2701. More specifically, the third receiving portion 276 is a portion of the outer surface of the first portion 2701 in the transverse direction.

[0068] like Figure 10 As shown, the second portion 2702 of this embodiment protrudes outward in the transverse direction from the first portion 2701. The second portion 2702 defines the outer end of the protrusion 27 in the transverse direction. The second receiving portion 272 is provided on the second portion 2702. More specifically, the second receiving portion 272 is a portion of the rear surface of the second portion 2702 in the front-to-back direction.

[0069] like Figure 4 As shown, the external terminal 24 of this embodiment is formed with a central hole 29. 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.

[0070] like Figure 6 As shown, in the connected state of the connector assembly 12 connected to the substrate 16, a portion of the fixed member 40 is located below the substrate 16 in the up-down direction. Figure 2 and Figure 9 , in the connected state of the connector assembly 12 connected to the substrate 16, the fixed member 40 is in contact with the ground layer 78A of the substrate 16. Figure 6 As shown, the fixed member 40 is in contact with the external terminal 24 in the connected state. Figure 14The fixed member 40 is made of metal. More specifically, the fixed member 40 is formed by stamping a metal plate and then bending the metal plate. It should be noted that the fixed member 40 preferably has a surface treatment, such as gold plating, to ensure reliable contact with the substrate 16 and the external terminal 24.

[0071] like Figure 14 As shown, the fixed member 40 has a spring portion 43 , a first contact portion 432 and two second contact portions 434 .

[0072] Reference Figure 14 The spring portion 43 of this embodiment is elastically deformable and supports the first contact portion 432 and the two second contact portions 434. The spring portion 43 defines the rear end of the fixed member 40 in the front-rear direction.

[0073] like Figure 14 As shown in FIG. 4 , the first contact portion 432 of this embodiment faces rearward in the front-to-back direction. Figure 16 As shown, the first contact portion 432 is located behind any one of the two second contact portions 434 in the front-to-back direction. The first contact portion 432 is located between the two second contact portions 434 in the transverse direction. Figure 5 As shown, the first contact portion 432 contacts the first receiving portion 252 in the connected state. Specifically, the first contact portion 432 and the first receiving portion 252 are electrically connected to each other in the connected state.

[0074] like Figure 15 As shown, each second contact portion 434 of this embodiment faces forward along the front-to-back direction. Figure 16 As shown, the two second contact portions 434 are separated from each other in the lateral direction. Figure 6 and Figure 19 The distance between the first contact portion 432 and any one of the two second contact portions 434 in the front-to-rear direction can be changed by elastic deformation of the spring portion 43 .

[0075] like Figure 6 As shown, 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. The second contact portion 434 contacts the second receiving portion 272 in the connected state. In the connected state, the second contact portion 434 of the fixed member 40, which is made of metal, is electrically connected to the second receiving portion 272 of the flange portion 25, which is made of metal. However, the present invention is not limited to this. Specifically, in the connected state, the second contact portion 434 and the second receiving portion 272 may not be electrically connected to each other.

[0076] Reference Figure 6In the connected state, the elastic deformation of the spring portion 43 causes the first contact portion 432 to press against the first receiving portion 252, while the two second contact portions 434 simultaneously press against the second receiving portions 272 of the two protruding portions 27, respectively. Thus, the connector assembly 12 of this embodiment is configured such that the fixed member 40 is securely connected to the external terminal 24 of the coaxial connector 20. Consequently, when the connector assembly 12 of this 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 external terminal 24 via the fixed member 40 in a highly reliable manner. That is, in the connector assembly 12 of this embodiment, the external terminal 24 can be stably connected to the ground layer 78A of the substrate 16, which can reliably reduce the reflection characteristics of signals propagating between the substrate 16 and the connector assembly 12.

[0077] like Figure 15 As shown, the spring portion 43 includes a main body 401 and two spring pieces 404 .

[0078] Reference Figure 14 , the main body 401 of this embodiment has a flat plate shape perpendicular to the up-down direction. The main body 401 defines the rear end of the fixed member 40 in the front-to-back direction. The first contact portion 432 is provided on the main body 401. The first contact portion 432 defines the rear end of the main body 401 in the front-to-back direction. The first contact portion 432 is a part of the rear end surface of the main body 401. Figure 17 As shown, the main body 401 has two cutouts 406. The two cutouts 406 are located at opposite ends of the main body 401 in the transverse direction. Each cutout 406 extends in the transverse direction. Figure 16 and Figure 17 The main body 401 has an upper surface 40U and a lower surface 40L.

[0079] like Figure 15 As shown, the two spring pieces 404 are respectively provided with a second contact portion 434. The two spring pieces 404 extend upward in the vertical direction from opposite ends of the main body 401 in the horizontal direction. Figure 14 and Figure 15 As shown, each spring piece 404 is provided with a slit 4042 extending in the up-down direction. The slit 4042 enables the spring piece 404 to be elastically deformed. The two spring pieces 404 correspond to the two cutouts 406 respectively. The slit 4042 of each spring piece 404 is connected to the corresponding cutout 406. Figure 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.

[0080] like Figure 19As shown, when the fixed member 40 is observed alone, the fixed member 40 has a second distance D2 in the front-to-back direction between the first contact portion 432 and any second contact portion 434. In other words, in the initial state where there is no elastic deformation of the spring piece 404, the fixed member 40 has a second distance D2 in the front-to-back direction between the first contact portion 432 and any second contact portion 434. Figure 12 and Figure 19 , the second distance D2 is greater than the first distance D1. As described above, the distance between the first contact portion 432 and any one of the two second contact portions 434 in the front-to-back direction can be changed by the elastic deformation of the spring portion 43. Therefore, in the connected state, while the spring portion 43 is elastically deformed, the spring portion 43 is sandwiched between the first receiving portion 252 and any one of the second receiving portions 272 of the coaxial connector 20 via the first contact portion 432 and the second contact portion 434. Figure 6 and Figure 12 In the connected state, the distance between the first contact portion 432 and any second contact portion 434 is equal to the first distance D1.

[0081] like Figure 14 As shown, each spring piece 404 has two third contact portions 405 .

[0082] like Figure 14 As shown, the third contact portion 405 of this embodiment faces inward in the transverse direction. Each third contact portion 405 is located below the upper end of the spring piece 404 in the vertical direction. Each third contact portion 405 is located above the first contact portion 432 in the vertical direction. In each spring piece 404, a slit 4042 is located between two third contact portions 405 along the front-to-back direction. Figure 16 As shown, each third contact portion 405 is positioned inwardly beyond the upper end of the spring piece 404 in the lateral direction. Each third contact portion 405 is located between the first contact portion 432 and the second contact portion 434 in the front-to-back direction. Each third contact portion 405 is located in front of the first contact portion 432 in the front-to-back direction. Each third contact portion 405 is located behind the second contact portion 434 in the front-to-back direction. Figure 18 Each third contact portion 405 is located above the second contact portion 434 in the vertical direction. In each spring piece 404, each third contact portion 405 is located inside the second contact portion 434 in the horizontal direction. Figure 1 and Figure 8 In the connected state, the third contact portion 405 contacts the third receiving portion 276 in the lateral direction.

[0083] like Figure 14As shown, the fixed member 40 has a pressed portion 42. As described below, the pressed portion 42 is a portion pressed against the substrate 16 in the connected state. According to this embodiment, the middle portion of the upper surface 40U in the lateral direction mainly serves as the pressed portion 42.

[0084] like Figure 16 As shown, the fixed member 40 of this embodiment is formed with two fixing holes 45. Each fixing hole 45 passes through the fixed member 40 in the up and down directions. Each fixing hole 45 has a substantially circular shape on the horizontal plane. Figure 9 , each fixing hole 45 is arranged at a position corresponding to each through hole 72 of the base plate 16 on the horizontal plane. The two fixing holes 45 arranged in this way are separated from each other in the lateral direction and are located at the same position as each other in the front-back direction. Figure 17 Each fixing hole 45 corresponds to a corresponding notch 406. Each fixing hole 45 is connected to a corresponding notch 406. The two spring leaves 404 correspond to two fixing holes 45, respectively. The slits 4042 of the spring leaves 404 are connected to the corresponding fixing holes 45 through the corresponding notches 406. It should be noted that the slit 4042 of one spring leaf 404 is not connected to the slit 4042 of the remaining spring leaf 404.

[0085] The fixed member 40 of this embodiment has the above-described configuration. However, the present invention is not limited thereto. For example, the shape of each fixing hole 45 is not particularly limited. In addition, the number of fixing holes 45 may be three or more.

[0086] Reference Figure 6 The connector assembly 12 and the substrate 16 connected thereto together form the structure 10. The substrate 16 of the structure 10 is located between the fixed member 40 and each protrusion 27 of the external terminal 24 in the vertical direction. Figure 3 The signal line 74 of the substrate 16 is pressed from below by the fixing member 40, so that the signal line 74 is pressed against and contacts the contact portion 214 of the center terminal 21. Thus, the contact portion 214 and the signal line 74 are electrically connected to each other. However, the present invention is not limited to this. Specifically, the contact portion 214 and the signal line 74 may be connected to each other by welding.

[0087] Reference Figure 9 , each screw 60 of this embodiment is a right-hand screw 60 made of metal. Each screw 60 is provided to correspond to each through hole 72 of the substrate 16. The number of screws 60 of this embodiment is two. However, the present invention is not limited thereto. For example, the connector assembly 12 may be provided with three or more screws 60 having different shapes from each other. Figure 2 and Figure 9In the connected state, each screw 60 is screwed into the screw hole 28 of each protrusion 27 through the fixing hole 45 and the through hole 72, so that each screw 60 is fixed to each protrusion 27, and at the same time, each screw 60 presses the fixed component 40 against the ground layer 78A of the substrate 16.

[0088] The connector assembly 12 of the present embodiment is configured to be connected to the substrate 16 by the following connection method. The connection method described below is merely an example and may be modified as needed.

[0089] Reference Figure 8 and Figure 9 The coaxial connector 20 and the substrate 16 are first arranged in the up-down 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 contact each other in the up-down direction, and at the same time, the screw hole 28 of the coaxial connector 20 and the through hole 72 of the substrate 16 are located at the same position as each other on the horizontal plane.

[0090] Next, the fixed member 40 is arranged in the up-down direction relative to the coaxial connector 20 and the substrate 16 so that the lower surface 70L of the substrate 16 faces the upper surface 40U of the fixed member 40 in the up-down direction, and at the same time, each guide portion 273 of the coaxial connector 20 and the second contact portion 434 of the corresponding spring piece 404 of the fixed member 40 are located at the same position as each other in the horizontal plane.

[0091] Then, the fixed member 40 is moved so as to approach the coaxial connector 20 and the substrate 16 in the vertical direction. Then, the second contact portion 434 of the fixed member 40 is brought into contact with the guide portion 273 of the coaxial connector 20, and the third contact portion 405 of the fixed member 40 is brought into contact with the protrusion 27 of the coaxial connector 20.

[0092] From this position, the fixed member 40 moves further, vertically approaching the coaxial connector 20 and the substrate 16. Then, as the spring portion 43 of the fixed member 40 elastically deforms, the following occurs: the first contact portion 432 of the fixed member 40 moves above the first receiving portion 252 of the coaxial connector 20; the second contact portion 434 of the fixed member 40 bridges over the guide portion 273 of the coaxial connector 20 and then bridges over 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, the upper surface 40U of the fixed member 40 vertically contacts the lower surface 70L of the substrate 16. As described above, each guide portion 273 extends upward and rearward. Therefore, when the fixed member 40 is connected to the coaxial connector 20, it is smoothly connected to the coaxial connector 20.

[0093] In this state, the first contact portion 432 of the fixed member 40 contacts the first receiving portion 252 of the coaxial connector 20 in the front-to-back direction, the second contact portion 434 of the fixed member 40 contacts the corresponding second receiving portion 272 of the coaxial connector 20 in the front-to-back direction, and the third contact portion 405 of the fixed member 40 contacts the third receiving portion 276 of the coaxial connector 20 in the lateral direction. Similarly, in this state, the elastic deformation of the spring portion 43 causes the first contact portion 432 to press against the first receiving portion 252, while the two second contact portions 434 press against the second receiving portions 272 of the two protruding portions 27, respectively.

[0094] Thereafter, each screw 60 is screwed into the screw hole 28 of the protrusion 27 of the coaxial connector 20 through the fixing hole 45 of the fixed member 40 and the through hole 72 of the substrate 16. Thus, the connector assembly 12 changes its state to a connected state in which the connector assembly 12 is connected to the substrate 16. The contact portion 214 of the center terminal 21 contacts the signal line 74 of the substrate 16 in the connected state.

[0095] like Figure 6 As shown, a portion of the fixed member 40 is located below the base plate 16 in the vertical direction in the connected state. Figure 2 and Figure 9 , in the connected state, the head of each screw 60 presses against the lower surface 40L of the fixed member 40 and presses the fixed member 40 upward. The upper surface 40U of the fixed member 40 thus pressed presses the substrate 16 against the lower surface 27L of the protrusion 27. As a result, the substrate 16 is clamped and held between the fixed member 40 and each protrusion 27. The substrate 16 thus clamped has a contact area located below the contact portion 214 of the center terminal 21. The pressed portion 42 of the fixed member 40 (see Figure 8 ) presses against the contact area of ​​substrate 16 and supports the contact area from below. If substrate 16 is a flexible board, the contact area of ​​substrate 16 will not bend even when force is applied from above. In the connected state, fixed member 40 presses against ground layer 78A of substrate 16.

[0096] That is, in the connected state, each screw 60 is screwed into the screw hole 28 of the protrusion 27 through the fixing hole 45 and the through hole 72, so that each screw 60 is fixed to each protrusion 27, and at the same time, each screw 60 presses the fixed component 40 against the ground layer 78A of the substrate 16.

[0097] Reference Figure 4 and Figure 9 In the connected state, the external terminal 24 is grounded to the ground layer 78A of the lower surface 70L of the substrate 16 via the protrusion 27 , the screw 60 , and the fixed member 40 .

[0098] While the external terminal 24 of this embodiment is configured such that the second receiving portion 272 forms a portion of the rear surface of the second portion 2702 of the protrusion 27 in the front-to-back direction, as described above, the present invention is not limited thereto. Specifically, the external terminal 24 may be modified as follows: the protrusion 27 is provided with a downwardly opening groove or recess; the inner surface of the groove or recess includes a rearward-facing surface; and this surface serves as the second receiving portion 272. In this case, in the connected state, the spring piece 404 of the fixed member 40 is received in the groove or recess from below, while the second contact portion 434 of the spring piece 404 contacts the second receiving portion 272 in the front-to-back direction. The second receiving portion 272 forms a rearward-facing surface of the inner surface of the groove or recess.

[0099] The configuration of the fixed member 40 of the connector assembly 12 is not limited to the above-described embodiment. For example, the fixed member 40 may be modified as follows.

[0100] like Figure 20 As shown, the fixed member 40A of the first modified example of the present invention includes a spring portion 43A, a first contact portion 432, and two second contact portions 434. The first contact portion 432 and the second contact portion 434 have the same structure as the first contact portion 432 and the second contact portion 434 of the above-described embodiment. Therefore, a detailed description thereof will be omitted.

[0101] See also Figure 20 The spring portion 43A of this modification is elastically deformable and supports the first contact portion 432 and the two second contact portions 434. The spring portion 43A defines the rear end of the fixed member 40A in the front-rear direction.

[0102] Reference Figure 9 and Figure 20 In the connected state, a connector assembly (not shown) according to a first variation of the present invention is connected to substrate 16. The connector assembly includes a coaxial connector 20, a fixed member 40A, and two screws 60. The elastic deformation of the spring portion 43A causes the first contact portion 432 to press against the first receiving portion 252, while the two second contact portions 434 press against the second receiving portions 272 of the two protrusions 27, respectively. Consequently, the connector assembly of this variation is also configured so that the fixed member 40A is securely connected to the external terminal 24 of the coaxial connector 20. Consequently, when the connector assembly of this variation is connected to substrate 16, the ground layer 78A of substrate 16 is electrically connected to the first receiving portion 252 of the flange portion 25 of the external terminal 24 via the fixed member 40A in a highly reliable manner. In other words, in this variation, the external terminal 24 can be stably connected to the ground layer 78A of substrate 16, and this can reliably reduce the reflection characteristics of signals propagating between substrate 16 and the connector assembly.

[0103] like Figure 20 As shown, the spring portion 43A includes a main body 401A and two spring pieces 404. The spring pieces 404 of this modification have the same structure as the spring pieces 404 of the previous embodiment. Therefore, a detailed description thereof will be omitted.

[0104] Reference Figure 20 , the main body portion 401A of this modification has a flat plate shape perpendicular to the up-down direction. The main body portion 401A defines the rear end of the fixed member 40A in the front-to-back direction. The first contact portion 432 is provided on the main body portion 401A. The first contact portion 432 defines the rear end of the main body portion 401A in the front-to-back direction. The first contact portion 432 is a portion of the rear end surface of the main body portion 401A. Unlike the above-mentioned embodiment, the main body portion 401A of this modification does not have a cutout 406.

[0105] Reference Figure 20 , when observing the fixed member 40A alone, the fixed member 40A has a second distance between the first contact portion 432 and any second contact portion 434 in the front-to-back direction. In other words, in the initial state where there is no elastic deformation of the spring piece 404, the fixed member 40A has a second distance between the first contact portion 432 and any second contact portion 434 in the front-to-back direction. Figure 12 and Figure 20 Therefore, in the connected state, the spring portion 43A is elastically deformed while being sandwiched between the first receiving portion 252 and any second receiving portion 272 of the coaxial connector 20 via the first contact portion 432 and the second contact portion 434 .

[0106] like Figure 20 As shown in FIG. 1 , the fixed member 40A has a pressed portion 42. The pressed portion 42 of this modified example has the same configuration as that of the pressed portion 42 of the above-described embodiment. Therefore, detailed description thereof will be omitted.

[0107] like Figure 21 As shown, the fixed member 40A of this modification is formed with two fixing holes 45A. Each fixing hole 45A passes through the fixed member 40A in the vertical direction. Each fixing hole 45A is circular in the horizontal plane. Figure 9 and Figure 20 Each fixing hole 45A is positioned horizontally at a position corresponding to each through-hole 72 of the base plate 16. The two fixing holes 45A thus arranged are separated from each other in the transverse direction and are located at the same position in the front-to-back direction. The two spring pieces 404 correspond to the two fixing holes 45A, respectively. As described above, the main body 401A of this variation does not have the cutout 406. Therefore, the slits 4042 of the spring pieces 404 of this variation do not connect to the corresponding fixing holes 45A.

[0108] like Figure 22 As shown, the fixed member 40B of the second modified example of the present invention includes a spring portion 43B, a first contact portion 432, and two second contact portions 434. The first contact portion 432 and the second contact portion 434 have the same structure as the first contact portion 432 and the second contact portion 434 of the above-described embodiment. Therefore, a detailed description thereof will be omitted.

[0109] See also Figure 22 The spring portion 43B of this modification is elastically deformable and supports the first contact portion 432 and the two second contact portions 434. The spring portion 43B defines the rear end of the fixed member 40B in the front-rear direction.

[0110] Reference Figure 9 and Figure 22 In the connected state, a connector assembly (not shown) according to a second variation of the present invention is connected to substrate 16. The connector assembly includes a coaxial connector 20, a fixed member 40B, and two screws 60. The elastic deformation of spring portion 43B causes first contact portion 432 to press against first receiving portion 252, while two second contact portions 434 press against second receiving portions 272 of two protrusions 27, respectively. Consequently, the connector assembly of this variation is also configured such that fixed member 40B is securely connected to external terminal 24 of coaxial connector 20. Consequently, when the connector assembly of this variation is connected to substrate 16, ground layer 78A of substrate 16 is electrically connected to first receiving portion 252 of flange portion 25 of external terminal 24 via fixed member 40B in a highly reliable manner. In other words, in this variation, external terminal 24 can be stably connected to ground layer 78A of substrate 16, which can effectively reduce reflection characteristics of signals propagating between substrate 16 and the connector assembly.

[0111] like Figure 22 As shown, the spring portion 43B includes a main body 401B and two spring pieces 404. The spring pieces 404 of this modification have the same structure as the spring pieces 404 of the previous embodiment. Therefore, a detailed description thereof will be omitted.

[0112] See also Figure 22The main body portion 401B of this modified example defines the rear end of the fixed member 40B in the front-to-back direction. The main body portion 401B has a first main body portion 4012 and a second main body portion 4014. The first main body portion 4012 is located behind the second main body portion 4014 in the front-to-back direction. The first main body portion 4012 and the second main body portion 4014 are separated from each other by a long cutout 4016 interposed therebetween. In other words, the long cutout 4016 is located between the first main body portion 4012 and the second main body portion 4014 in the front-to-back direction. The first contact portion 432 is provided on the main body portion 401B. Specifically, the first contact portion 432 is provided on the first main body portion 4012. The first contact portion 432 defines the rear end of the main body portion 401B in the front-to-back direction. The first contact portion 432 defines the rear end of the first main body portion 4012 in the front-to-back direction. The first contact portion 432 is a portion of the rear end surface of the main body portion 401B. Specifically, the first contact portion 432 is a portion of the rear end surface of the first main body portion 4012.

[0113] Reference Figure 22 , when the fixed member 40B is observed alone, the fixed member 40B has a second distance between the first contact portion 432 and any second contact portion 434 in the front-to-back direction. In other words, in the initial state where there is no elastic deformation of the spring piece 404, the fixed member 40B has a second distance between the first contact portion 432 and any second contact portion 434 in the front-to-back direction. Figure 12 and Figure 22 Therefore, in the connected state, the spring portion 43B is elastically deformed while being sandwiched between the first receiving portion 252 and any second receiving portion 272 of the coaxial connector 20 via the first contact portion 432 and the second contact portion 434 .

[0114] like Figure 22 As shown in FIG. 1 , the fixed member 40B has a pressed portion 42. The pressed portion 42 of this modification has the same configuration as that of the pressed portion 42 of the above-described embodiment. Therefore, detailed description thereof will be omitted.

[0115] like Figure 23 As shown, the fixed member 40B of this modification is formed with two fixing holes 45B. Each fixing hole 45B passes through the fixed member 40B in the up-down direction. Each fixing hole 45B has a circular shape on the horizontal plane. Figure 9 and Figure 22, each fixing hole 45B is arranged at a position corresponding to each through hole 72 of the base plate 16 on the horizontal plane. The two fixing holes 45B arranged in this way are separated from each other in the lateral direction and are located at the same position as each other in the front-to-back direction. The two spring leaves 404 correspond to the two fixing holes 45B respectively. The slits 4042 of the spring leaves 404 of this modification are not connected to the corresponding fixing holes 45B. The slits 4042 of the two spring leaves 404 are connected to each other in the lateral direction. Specifically, the slits 4042 of the two spring leaves 404 are connected to each other through the long slit 4016. Through this structure, the spring portion 43B of this modification is easily elastically deformed compared with the spring portions 43, 43A of the above-mentioned embodiment and the first modification.

[0116] like Figure 24 As shown, the fixed member 40C of the third modified example of the present invention includes a spring portion 43C, a first contact portion 432C, and two second contact portions 434. Specifically, the spring portion 43C includes a main body portion 401C and two spring pieces 404. The spring portion 43C and the second contact portion 434 have the same structure as the spring portion 43 and the second contact portion 434 of the above-described embodiment. Therefore, a detailed description thereof will be omitted.

[0117] like Figure 24 As shown, the first contact portion 432C of this modification faces rearward in the front-to-back direction. The first contact portion 432C is located behind any one of the two second contact portions 434 in the front-to-back direction. The first contact portion 432C is located between the two second contact portions 434 in the lateral direction. The first contact portion 432C includes a single protrusion 433. The protrusion 433 is located in the middle of the fixed member 40C in the lateral direction. The protrusion 433 is supported by the spring portion 43C so that the protrusion 433 protrudes rearward in the front-to-back direction. Figure 24 and Figure 5 In the connection state of the connector assembly (not shown) of the third modification of the present invention connected to the substrate 16, the first contact portion 432C contacts the first receiving portion 252, and the connector assembly includes the coaxial connector 20, the fixed member 40C and the two screws 60. Specifically, the first contact portion 432C and the first receiving portion 252 are electrically connected to each other in this connection state. Figure 24 and Figure 3 In this connected state, the protrusion 433 is located between the two protrusions 27 in the lateral direction. In this connected state, the protrusion 433 is located at the same position in the lateral direction as the contact portion 214 of the center terminal 21. In this connected state, the protrusion 433 is located near the contact portion 214 of the center terminal 21.

[0118] Reference Figure 8 and Figure 24In this connected state, the elastic deformation of the spring portion 43C causes the first contact portion 432C to press against the first receiving portion 252, while the two second contact portions 434 are pressed against the second receiving portions 272 of the two protrusions 27, respectively. Thus, the connector assembly of this modification is also configured so that the fixed member 40C is securely connected to the external terminal 24 of the coaxial connector 20. Therefore, when the connector assembly 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 external terminal 24 via the fixed member 40C in a highly reliable manner. In other words, in this modification as well, the external terminal 24 can be stably connected to the ground layer 78A of the substrate 16, which can effectively reduce the reflection characteristics of the signal propagating between the substrate 16 and the connector assembly.

[0119] As described above, the first contact portion 432C located near the contact portion 214 of the center terminal 21 of the coaxial connector 20 is pressed against the first receiving portion 252 in the front-to-rear direction in this connected state. This allows the fixed member 40C of this modification to always be in contact with the flange portion 25 near the contact portion 214 of the center terminal 21 of the coaxial connector 20 in this connected state.

[0120] like Figure 25 As shown, the fixed member 40D of the fourth modified example of the present invention includes a spring portion 43D, a first contact portion 432D, and two second contact portions 434. Specifically, the spring portion 43D includes a main body portion 401D and two spring pieces 404. The spring portion 43D and the second contact portion 434 have the same structure as the spring portion 43 and the second contact portion 434 of the above-described embodiment. Therefore, a detailed description thereof will be omitted.

[0121] like Figure 25 As shown, the first contact portion 432D of this modification faces rearward in the front-to-back direction. The first contact portion 432D is located behind any one of the two second contact portions 434 in the front-to-back direction. The first contact portion 432D is located between the two second contact portions 434 in the transverse direction. The first contact portion 432D includes two protrusions 433D. However, the present invention is not limited to this. Specifically, the first contact portion 432D may include at least one protrusion 433D. The two protrusions 433D are arranged mirror-symmetrically with respect to a plane perpendicular to the transverse direction. Each protrusion 433D is supported by a spring portion 43D so that each protrusion 433D protrudes rearward in the front-to-back direction. Refer to Figure 25 and Figure 5In the connection state of the connector assembly (not shown) of the fourth modification of the present invention connected to the substrate 16, the first contact portion 432D contacts the first receiving portion 252, and the connector assembly includes the coaxial connector 20, the fixed member 40D and the two screws 60. Specifically, the first contact portion 432D and the first receiving portion 252 are electrically connected to each other in this connection state. Figure 25 and Figure 3 In this connected state, the two protrusions 433D are located on opposite sides of the contact portion 214 of the center terminal 21 in the lateral direction. In this connected state, each protrusion 433D is located around the contact portion 214 of the center terminal 21.

[0122] Reference Figure 25 and Figure 8 In this connected state, the elastic deformation of the spring portion 43D causes the first contact portion 432D to press against the first receiving portion 252, while the two second contact portions 434 simultaneously press against the second receiving portions 272 of the two protrusions 27, respectively. Thus, the connector assembly of this modification is also configured so that the fixed member 40D is securely connected to the external terminal 24 of the coaxial connector 20. Therefore, when the connector assembly 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 external terminal 24 via the fixed member 40D in a highly reliable manner. In other words, in this modification as well, the external terminal 24 can be stably connected to the ground layer 78A of the substrate 16, which can effectively reduce the reflection characteristics of the signal propagating between the substrate 16 and the connector assembly.

[0123] As described above, the first contact portion 432D located around the contact portion 214 of the center terminal 21 of the coaxial connector 20 is pressed against the first receiving portion 252 in the front-to-rear direction in this connected state. This allows the fixed member 40D of this modification to always be in contact with the flange portion 25 around the contact portion 214 of the center terminal 21 of the coaxial connector 20 in this connected state.
