[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-331679 Summary of the Invention [Problem to be solved by the invention]

[0004] In the plug connector and receptacle connector described in Patent Document 1, the first ground terminal and the second ground terminal are in surface contact. However, minute irregularities exist on the surfaces of the first ground terminal and the second ground terminal. In this case, a minute gap is formed between the first ground terminal and the second ground terminal. When such a gap is formed, capacitance is formed between the first ground terminal and the second ground terminal. Furthermore, the first ground terminal and the second ground terminal have an inductance component. The inductance component and capacitance form an LC resonant circuit. Such an LC resonant circuit causes noise generation. In other words, the LC resonant circuit affects the transmission of high-frequency signals between the plug connector and the receptacle connector.

[0005] Therefore, an object of the present invention is to provide a connector set capable of suppressing the influence of an LC resonance circuit caused by the capacitance between a first ground terminal and a second ground terminal on the transmission of a high-frequency signal between a first connector and a second connector.

[0009] (Embodiment) [Structure of Connector Set 1] Hereinafter, a connector set 1 including a first connector 10 and a second connector 110 according to an embodiment of the present invention will be described. FIG. 1 is a perspective view of the connector set 1.

[0010] Hereinafter, as shown in FIG. 1, the downward direction is the direction in which the second connector 110 and the first connector 10 are arranged in this order. Also, the rightward direction is the direction in which the first signal terminals 13a to 13k are arranged in this order in the first connector 10. The vertical axis, the horizontal axis, and the front-rear axis are orthogonal to each other. However, the vertical axis, the horizontal axis, and the front-rear axis in this specification are axes defined for convenience of explanation and do not necessarily coincide with the vertical axis, the horizontal axis, and the front-rear axis when the connector set 1 is in use.

[0011] The connector set 1 is used, for example, to connect two circuit boards. The connector set 1 includes a first connector 10 and a second connector 110 as shown in FIG. 1. When the first connector 10 and the second connector 110 are coupled, the second connector 110 is positioned above the first connector 10.

[0012] [Structure of the First Connector] Next, the structure of the first connector 10 will be described. FIG. 2 is a perspective view of the first connector 10 and the second connector 110.

[0013] The first connector 10 includes a first body member 12, first signal terminals 13a to 13v, a first ground terminal 14r, a second ground terminal 14l, fifth ground terminals 16ra, rb, and sixth ground terminals 16la, 16lb as shown in FIG. 2.

[0014] The first body member 12 includes a protrusion 12a, a frame portion 12b, and a connecting portion 12c as shown in FIG. 2. The protrusion 12a extends in the left-right direction when viewed downward. More specifically, the protrusion 12a has a rectangular parallelepiped shape. The protrusion 12a has two long sides extending in the left-right direction and two short sides extending in the front-rear direction when viewed downward.

[0015] When viewed from below, the frame portion 12b has a ring shape that surrounds the periphery of the protrusion portion 12a. When viewed from below, the frame portion 12b has a rectangular inner edge and a rectangular outer edge. Therefore, the frame portion 12b has front and rear edges extending in the left-right direction and left and right edges extending in the front-to-back direction. When viewed from below, the protrusion portion 12a is located within the area surrounded by the frame portion 12b. The protrusion portion 12a does not contact the frame portion 12b.

[0016] As shown in Fig. 2, the connecting portion 12c is located between the protrusion 12a and the frame portion 12b when viewed from below, and connects the protrusion 12a and the frame portion 12b. In this embodiment, the connecting portion 12c connects the lower portion of the protrusion 12a and the lower portion of the frame portion 12b. The material of the first main body member 12 is an insulating material. The material of the first main body member 12 is, for example, resin.

[0017] The first ground terminal 14r is connected to a ground potential. As shown in FIG. 2, the first ground terminal 14r is supported by the first body member 12. Specifically, the first ground terminal 14r is supported by the right side, front side, and rear side of the frame portion 12b. The structure of the first ground terminal 14r will be described below.

[0018] As shown in FIGS. 2 and 3, the first ground terminal 14r includes a first ground terminal main body portion 14ra, a first ground terminal front portion 14rb, a first ground terminal rear portion 14rc, and a first ground terminal cover portion 14rd. The first ground terminal main body portion 14ra is provided on the left surface, upper surface, and right surface of the right side of the frame portion 12b. A part of the first ground terminal main body portion 14ra is embedded in the right side of the frame portion 12b as shown in FIG. 2. The first ground terminal front portion 14rb is provided on the front surface, upper surface, and rear surface of the right end portion of the front side of the frame portion 12b. A part of the first ground terminal front portion 14rb is embedded in the front side of the frame portion 12b.

The first ground terminal cover portion 14rd is provided at the right end portion of the protrusion portion 12a. A part of the first ground terminal cover portion 14rd is embedded in the right end portion of the protrusion portion 12a.

[0019] The second ground terminal 14l is connected to the ground potential. The second ground terminal 14l is supported by the first main body member 12 as shown in FIG. 2. The second ground terminal 14l is located to the left of the first ground terminal 14r. Since the second ground terminal 14l has a structure symmetric to the first ground terminal 14r, the description thereof is omitted. The second ground terminal 14l is manufactured by bending a metal member. The material of the second ground terminal 14l is, for example, a copper-based material such as phosphor bronze.

[0020] High-frequency signals are input to and output from the first signal terminals 13a to 13v. The first signal terminals 13a to 13v are supported by the first main body member 12. The first signal terminals 13a to 13v are located between the first ground terminal 14r and the second ground terminal 14l in the left-right direction. More specifically, portions of the first signal terminals 13a to 13k are embedded in the rear edge of the frame portion 12b. As a result, the first signal terminals 13a to 13k are supported by the frame portion 12b so as to be aligned in the left-right direction in the area behind the protrusion 12a. The first signal terminals 13a to 13k are aligned in a line from left to right in this order. Portions of the first signal terminals 13l to 13v are embedded in the front edge of the frame portion 12b. The first signal terminals 13l to 13v are supported by the frame portion 12b so as to be aligned in the left-right direction in the area in front of the protrusion 12a. The first signal terminals 13l to 13v are located in front of the first signal terminals 13a to 13k. The first signal terminals 13l to 13v are lined up in a row from left to right. The first signal terminals 13l to 13v are made by bending a rod-shaped metal member. The first signal terminals 13a to 13v are made of a copper-based material such as phosphor bronze.

[0021] The fifth ground terminals 16ra and 16rb are connected to a ground potential. As shown in FIG. 2, the fifth ground terminals 16ra and 16rb are supported by the first body member 12. However, the fifth ground terminal 16rb is not shown because it is not visible. Specifically, the fifth ground terminal 16ra is located between the first ground terminal front portion 14rb and the first signal terminal 13v. The fifth ground terminal 16ra is supported by the front edge of the frame portion 12b. However, the fifth ground terminal 16ra can be elastically deformed in the front-to-rear direction. The fifth ground terminal 16rb is located between the first ground terminal rear portion 14rc and the first signal terminal 13k. The fifth ground terminal 16rb is supported by the rear edge of the frame portion 12b. However, the fifth ground terminal 16rb can be elastically deformed in the front-to-rear direction. The fifth ground terminals 16ra and 16rb are fabricated by bending a rod-shaped metal member. The fifth ground terminals 16ra and 16rb are made of a copper-based material such as phosphor bronze.

[0022] The sixth ground terminals 16la, 16lb are connected to a ground potential. As shown in FIG. 2, the sixth ground terminals 16la, 16lb are supported by the first body member 12. However, since the sixth ground terminal 16lb is not visible, it is not shown in the drawings. The sixth ground terminals 16la, 16lb have a structure symmetrical to the fifth ground terminals 16ra, 16rb, and therefore their description will be omitted. The sixth ground terminals 16la, 16lb are fabricated by bending a metal member. The sixth ground terminals 16la, 16lb are made of a copper-based material such as phosphor bronze.

[0023] The first connector 10 described above is mounted on a first circuit board (not shown) with the bottom surface of the first body member 12 facing the first circuit board. Specifically, portions of the first signal terminals 13a to 13v, the first ground terminal 14r, the second ground terminal 14l, the fifth ground terminals 16ra and 16rb, and the sixth ground terminals 16la and 16lb are exposed from the bottom surface of the first body member 12. Solder is then applied to each of these portions. As a result, the first signal terminals 13a to 13v, the first ground terminal 14r, the second ground terminal 14l, the fifth ground terminals 16ra and 16rb, and the sixth ground terminals 16la and 16lb are connected to electrodes of the first circuit board.

[0024] [Structure of the second connector] Next, a description will be given of the structure of second connector 110. FIG.

[0025] As shown in FIG. 3, the second connector 110 includes a second main body member 112, second signal terminals 113a to 113v, a third ground terminal 114r, and a fourth ground terminal 114l.

[0026] The second main body member 112 includes a bottom surface portion 112a and a frame portion 112b. The frame portion 112b has a ring shape when viewed from above. More specifically, the frame portion 112b has a rectangular outer edge and a rectangular inner edge when viewed from above. Each of the outer edge and the inner edge of the frame portion 112b has two long sides extending in the left-right direction and two short sides extending in the front-rear direction when viewed from above. As shown in FIG. 4, the bottom surface portion 112a covers the upper surface of the area surrounded by the frame portion 112b when viewed from above. The second main body member 112 is made of an insulating material. The second main body member 112 is made of, for example, resin.

[0027] The third ground terminal 114r is connected to a ground potential. The third ground terminal 114r is supported by the second body member 112. Specifically, the third ground terminal 114r is supported by the right side, front side, and rear side of the frame portion 112b. The structure of the third ground terminal 114r will be described below.

[0028] As shown in FIG. 3, the third ground terminal 114r includes a third ground terminal main body 114ra, a third ground terminal front portion 114rb, and a third ground terminal rear portion 114rc. The third ground terminal main body 114ra is provided on the left, top, and right surfaces of the right side of the frame portion 12b. A portion of the third ground terminal main body 114ra is embedded in the right side of the frame portion 112b, as shown in FIG. 4. The third ground terminal front portion 114rb is provided on the front, top, and rear surfaces of the right end of the front side of the frame portion 112b. A portion of the third ground terminal front portion 114rb is embedded in the front side of the frame portion 112b. The third ground terminal rear portion 114rc is provided on the front, top, and rear surfaces of the right end of the rear side of the frame portion 112b. A portion of the third ground terminal rear portion 114rc is embedded in the rear side of the frame portion 112b.

[0029] The fourth ground terminal 114l is connected to a ground potential. As shown in FIG. 3, the fourth ground terminal 114l is supported by the first body member 12. The fourth ground terminal 114l is located to the left of the third ground terminal 114r. The structure of the fourth ground terminal 114l is symmetrical to that of the third ground terminal 114r, and therefore a description thereof will be omitted. The third ground terminal 114r and the fourth ground terminal 114l are fabricated by bending a metal member. The third ground terminal 114r and the fourth ground terminal 114l are made of a copper-based material such as phosphor bronze.

[0030] High-frequency signals are input to and output from the second signal terminals 113a to 113v. The second signal terminals 113a to 113v are supported by the second main body member 112. The second signal terminals 113a to 113v are located between the third ground terminal 114r and the fourth ground terminal 114l in the left-right direction. More specifically, portions of the second signal terminals 113a to 113k are embedded in the rear edge of the frame portion 112b. The second signal terminals 113a to 113k are lined up in this order from left to right. Portions of the second signal terminals 113l to 113v are embedded in the front edge of the frame portion 112b. The second signal terminals 113l to 113v are located in front of the second signal terminals 113a to 113k. The second signal terminals 113l to 113v are lined up in this order from left to right. The second signal terminals 113a to 113v are made by bending a rod-shaped metal member, and are made of a copper-based material such as phosphor bronze.

[0031] In the second connector 110 as described above, the second connector 110 is mounted on a second circuit board (not shown) such that the upper surface of the second body member 112 faces the circuit board. Specifically, a part of the second signal terminals 113a to 113v, a part of the third ground terminal 114r, and a part of the fourth ground terminal 114l are exposed from the bottom surface of the second body member 112. Therefore, solder is applied to each of these parts. As a result, each of the second signal terminals 113a to 113v, the third ground terminal 114r, and the fourth ground terminal 114l is connected to an electrode of the second circuit board.

[0032] [Relationship between the first ground terminal 14r and the third ground terminal 114r] Here, the relationship between the first ground terminal 14r and the third ground terminal 114r will be described. FIG. 4 is a perspective view of the terminals of the connector set 1. FIG. 5 is a cross-sectional view taken along line A-A in FIG. 1. FIG. 6 is a cross-sectional view taken along line B-B in FIG. 1.

[0033] As shown in FIG. 4, each of the first signal terminals 13a to 13v is in contact with the second signal terminals 113a to 113v. Also, the fifth ground terminals 16ra, 16rb are in contact with the third ground terminal 114r while being elastically deformed. The sixth ground terminals 16la, 16lb are in contact with the fourth ground terminal 114la while being elastically deformed.

[0034] The first ground terminal 14r and the third ground terminal 114r may or may not be in contact. In the present embodiment, the first ground terminal 14r and the third ground terminal 114r are not in contact.

[0035] As shown in FIG. 5, the first ground terminal 14r includes a first portion 14raa extending in the vertical direction. The first portion 14raa is a part of the first ground terminal main body 14ra. The first portion 14raa is exposed from the left surface of the right edge of the frame portion 12b. More specifically, the first portion 14raa has a first main surface, a second main surface, and two first side surfaces. The first main surface is exposed from the first body member 12. The second main surface and the two first side surfaces of the first portion 14raa are embedded in the first body member 12, thereby holding the first portion 14raa in place in the first body member 12. This prevents the first portion 14raa from elastically deforming.

[0036] As shown in FIG. 5, the third ground terminal 114r includes a second portion 114raa extending in the vertical direction. The second portion 114raa is a part of the third ground terminal main body 114ra. The second portion 114raa is exposed from the right surface of the right edge of the frame portion 112b. More specifically, the second portion 114raa has a third main surface, a fourth main surface, and two second side surfaces. The third main surface is exposed from the second main body member 112. The fourth main surface and the two second side surfaces of the second portion 114raa are embedded in the second main body member 112, thereby holding the second portion 114raa in place in the second main body member 112. This prevents the second portion 114raa from elastically deforming.

[0037] Here, the first portion 14raa and the second portion 114raa face each other. As a result, a space Sp1 exists between the first portion 14raa and the second portion 114raa. The first portion 14raa is located to the right of the second portion 114raa. Because the first portion 14raa or the second portion 114raa is tilted with respect to the vertical direction, the space Sp1 becomes larger from bottom to top. In this embodiment, the first portion 14raa is tilted with respect to the vertical direction. The upper end of the first portion 14raa is located to the right of the lower end of the first portion 14raa. The second portion 114raa is not tilted with respect to the vertical direction. However, as described below, the first portion 14raa is not in contact with the second portion 114raa.

[0038] The right side of the frame portion 12b of the first main body member 12 contacts the second portion 114raa, so that the first portion 14raa and the second portion 114raa face each other, and a space Sp1 exists between the first portion 14raa and the second portion 114raa. Specifically, the right side of the frame portion 12b of the first main body member 12 has a first surface S1. The first surface S1 faces leftward. The first surface S1 is located to the left of the first portion 14raa. The first surface S1 contacts the second portion 114raa. As a result, the first portion 14raa is not in contact with the second portion 114raa.

[0039] As shown in FIG. 5, the first ground terminal 14r includes a first portion 14rda extending in the vertical direction. The first portion 14rda is a part of the first ground terminal cover portion 14rd. The first portion 14rda is exposed from the right surface of the protrusion 12a. More specifically, the first portion 14rda has a first main surface, a second main surface, and two first side surfaces. The first main surface is exposed from the first main body member 12. The second main surface and the two first side surfaces of the first portion 14rda are embedded in the first main body member 12, thereby holding the first portion 14rda in place in the first main body member 12. This prevents the first portion 14rda from elastically deforming.

[0040] As shown in FIG. 5, the third ground terminal 114r includes a second portion 114rab extending in the vertical direction. The second portion 114rab is a part of the third ground terminal main body 114ra. The second portion 114rab is exposed from the left surface of the right edge of the frame portion 112b. More specifically, the second portion 114rab has a third main surface, a fourth main surface, and two second side surfaces. The third main surface is exposed from the second main body member 112. The fourth main surface and the two second side surfaces of the second portion 114rab are embedded in the second main body member 112, thereby holding the second portion 114rab to the second main body member 112. This prevents the second portion 114rab from elastically deforming.

[0041] Here, the first part 14rda and the second part 114rab face each other. As a result, a space Sp2 exists between the first part 14rda and the second part 114rab. The first part 14rda is located to the left of the second part 114rab. Due to the inclination of the first part 14rda or the second part 114rda with respect to the vertical direction, the space Sp2 becomes larger as going from bottom to top. In this embodiment, the first part 14rda is inclined with respect to the vertical direction. The upper end of the first part 14rda is located to the left of the lower end of the first part 14rda. However, as will be described below, the first part 14rda is not in contact with the second part 114rab.

[0042] When the right end of the protrusion 12a of the first main body member 12 contacts the second part 114rab, the first part 14rda and the second part 114rba face each other, and a space Sp2 exists between the first part 14rda and the second part 114rba. Specifically, the right end of the protrusion 12a of the first main body member 12 has a first surface S11. The first surface S11 faces the right direction. The first surface S11 is located to the right of the first part 14rda. And the first surface S11 is in contact with the second part 114rab. As a result, the first part 14rda is not in contact with the second part 114rab.

[0043] As shown in FIG. 6, the first ground terminal 14r includes a first part 14rba extending in the vertical direction. The first part 14rba is a part of the first ground terminal front part 14rb. The first part 14rba is exposed from the rear surface of the front side of the frame part 12b. More specifically, the first part 14rba has a first main surface, a second main surface, and two first side surfaces. The first main surface is exposed from the first main body member 12. Since the second main surface and the two first side surfaces of the first part 14rba are embedded in the first main body member 12, the first part 14rba is held by the first main body member 12. As a result, the first part 14rba cannot be elastically deformed.

[0044] As shown in FIG. 6, the third ground terminal 114r includes a second portion 114rba that extends in the vertical direction. The second portion 114rba is a part of the front portion 114rb of the third ground terminal. The second portion 114rba is exposed from the front surface of the front side of the frame portion 112b. More specifically, the second portion 114rba has a third main surface, a fourth main surface, and two second side surfaces. The third main surface is exposed from the second main body member 112. Since the fourth main surface and the two second side surfaces of the second portion 114rba are buried in the second main body member 112, the second portion 114rba is held by the second main body member 112. Thereby, the second portion 114rba cannot be elastically deformed.

[0045] Here, the first portion 14rba and the second portion 114rba face each other. Thereby, a space Sp3 exists between the first portion 14rba and the second portion 114rba. The first portion 14rba is located in front of the second portion 114rba. Due to the inclination of the first portion 14rba or the second portion 114rba with respect to the vertical direction, the space Sp3 becomes larger as it goes from bottom to top. In the present embodiment, the first portion 14rba is inclined with respect to the vertical direction. The upper end of the first portion 14rba is located in front of the lower end of the first portion 14rba. However, as will be described below, the first portion 14rba does not contact the second portion 114rba.

[0046] Since the front side of the frame portion 12b of the first main body member 12 contacts the second portion 114rba, the first portion 14rba and the second portion 114rba face each other, and a space Sp3 exists between the first portion 14rba and the second portion 114rba. Specifically, the front side of the frame portion 12b of the first main body member 12 has a first surface S21. The first surface S21 faces backward. The first surface S21 is located behind the first portion 14rba. And the first surface S21 contacts the second portion 114rba. Thereby, the first portion 14rba does not contact the second portion 114rba.

[0047] Note that since the rear part 14rc of the first ground terminal and the rear part 114rc of the third ground terminal have a front-rear symmetric structure with the front part 14rb of the first ground terminal and the front part 114rb of the third ground terminal, the description thereof is omitted. Further, since the second ground terminal 14l and the fourth ground terminal 114l have a left-right symmetric structure with the first ground terminal 14r and the third ground terminal 114r, the description thereof is omitted.

[0048] [Effect] According to the connector set 1, it is possible to suppress the LC resonance circuit caused by the capacitance between the first ground terminal 14r and the third ground terminal 114r from affecting the transmission of the high-frequency signal between the first connector 10 and the second connector 110. More specifically, when the right side of the frame portion 12b of the first main body member 12 contacts the second portion 114raa, the first portion 14raa and the second portion 114raa face each other, and a space Sp1 exists between the first portion 14raa and the second portion 114raa. As a result, the distance between the first portion 14raa and the second portion 114raa increases, so that the capacitance formed between the first ground terminal 14r and the third ground terminal 114r decreases. Therefore, the resonance frequency of the LC resonance circuit increases. As a result, the resonance frequency of the LC resonance circuit is out of the band of the high-frequency signal transmitted through the first connector 10 and the second connector 110. From the above, according to the connector set 1, it is possible to suppress the LC resonance circuit caused by the capacitance between the first ground terminal 14r and the third ground terminal 114r from affecting the transmission of the high-frequency signal between the first connector 10 and the second connector 110.

[0049] According to the connector set 1, even for the following reasons, it is possible to suppress the LC resonance circuit caused by the capacitance between the first ground terminal 14r and the third ground terminal 114r from affecting the transmission of high-frequency signals between the first connector 10 and the second connector 110. More specifically, as shown in FIG. 5, the first ground terminal 14r includes a first portion 14raa extending in the vertical direction. As shown in FIG. 5, the third ground terminal 114r includes a second portion 114raa extending in the vertical direction. The first portion 14raa and the second portion 114raa face each other, and a space Sp1 exists between the first portion 14raa and the second portion 114raa. Since the first portion 14raa or the second portion 114raa is inclined with respect to the vertical direction, the space Sp1 becomes larger as it goes from bottom to top. Thereby, since the distance between the first portion 14raa and the second portion 114raa becomes larger, the capacitance formed between the first ground terminal 14r and the third ground terminal 114r becomes smaller. Therefore, the resonance frequency of the LC resonance circuit becomes higher. As a result, the resonance frequency of the LC resonance circuit is out of the band of the high-frequency signals transmitted through the first connector 10 and the second connector 110. From the above, according to the connector set 1, it is possible to suppress the LC resonance circuit caused by the capacitance between the first ground terminal 14r and the third ground terminal 114r from affecting the transmission of high-frequency signals between the first connector 10 and the second connector 110.

[0050] By the way, the first portion 14raa cannot be elastically deformed by being held by the first main body member 12. The second portion 114raa cannot be elastically deformed by being held by the second main body member 112. Therefore, depending on the state in which the first connector 10 and the second connector 110 are coupled, the first portion 14raa and the second portion 114raa may or may not be in contact with each other. In the present embodiment, the first portion 14raa is not in contact with the second portion 114raa. Therefore, the fifth ground terminals 16ra, 16rb contact the third ground terminal 114r while being elastically deformed. Thereby, the fifth ground terminals 16ra, 16rb are surely brought into contact with the third ground terminal 114r.

[0051] Also, as described above, the first portion 14raa is not in contact with the second portion 114raa. In this case, a capacitance is likely to be formed between the first ground terminal 14r and the third ground terminal 114r. That is, the LC resonance circuit caused by the capacitance between the first ground terminal 14r and the third ground terminal 114r is likely to affect the transmission of the high-frequency signal between the first connector 10 and the second connector 110. Therefore, in the connector set 1, since the first portion 14raa is inclined with respect to the vertical direction, the space Sp1 increases as it goes from bottom to top. Thereby, it is possible to suppress the LC resonance circuit caused by the capacitance between the first ground terminal 14r and the third ground terminal 114r from affecting the transmission of the high-frequency signal between the first connector 10 and the second connector 110.

[0052] (Modification example) Hereinafter, the connector set 1a according to the modification example will be described with reference to the drawings. FIG. 7 is a cross-sectional view of the connector set 1a.

[0053] The connector set 1a is different from the connector set 1 in that the second portion 114raa is in contact with the first ground terminal 14r. More specifically, the direction from the first portion 14rda to the second portion 114rab is defined as the first direction. The first direction is the right direction. The first ground terminal 14r further includes a first portion 14raa (third portion) located on the right (first direction) with respect to the first portion 14rda. The third ground terminal 114r further includes a second portion 114raa (fourth portion) located on the right (first direction) with respect to the second portion 114rab. When the second portion 114rab is pushed in the right direction (first direction) by the first body member 12, the second portion 114raa (fourth portion) is pressed against the first portion 14raa (third portion). Since the other structure of the connector set 1a is the same as that of the connector set 1, the description thereof will be omitted. The connector set 1a can achieve the same effect as the connector set 1.

[0054] (Other embodiments) The connector set according to the present invention is not limited to the connector set 1 and can be changed within the scope of the gist thereof. Further, the structures of the connector set 1 may be arbitrarily combined.

[0055] In addition, when the right side of the frame portion 112b of the second main body member 112 contacts the first portion 14raa, the first portion 14raa and the second portion 114raa face each other, and a space Sp1 may exist between the first portion 14raa and the second portion 114raa. In this case, the second main body member 112 has a second surface S2. The second surface S2 is in contact with the first portion 14raa.

[0056] Note that the number of the first signal terminals may be one or more. Also, the number of the second signal terminals may be one or more.

[0057] Note that the second portion may be inclined with respect to the vertical direction. In this case, the first portion may be inclined with respect to the vertical direction or may not be inclined.
