[0003] [Patent Document 1] Patent Application 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 and a connector that can prevent an LC resonant circuit caused by the capacitance between the first terminal and the second terminal from affecting the transmission of high-frequency signals between the first connector and the second connector.

[0009] (Embodiment) [Connector set 1 structure] A connector set 1 according to one embodiment of the present invention, which includes a first connector 10 and a second connector 110, will be described below. FIG.

[0010] 1, the downward direction is the direction in which the second connector 110 and the first connector 10 are lined up in this order. The rightward direction is the direction in which the first signal terminals 13a to 13e are lined up in this order in the first connector 10. The up-down axis, the left-right axis, and the front-rear axis are perpendicular to one another. However, the up-down axis, the left-right axis, and the front-rear axis in this specification are axes defined for the convenience of explanation, and do not have to coincide with the up-down axis, the left-right 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. As shown in Fig. 1, the connector set 1 includes a first connector 10 and a second connector 110. When the first connector 10 and the second connector 110 are coupled together, the first connector 10 is located below the second connector 110.

[0012] [Structure of the first connector] Next, a description will be given of the structure of the first connector 10. FIG.

[0013] As shown in FIG. 2, the first connector 10 includes a first resin main body member 12, first signal terminals 13a to 13j, and first ground terminals 141a, 141b, 141c, 141a, 141b, and 141c.

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

[0015] When viewed downward, the frame portion 12b has a rectangular ring shape with a front long side 12bf and a rear long side 12bb extending along the left-right axis, and a left short side 12bl and a right short side 12br extending along the front-rear axis. The front long side 12bf is located in front of the rear long side 12bb. The left short side 12bl is located to the left of the right short side 12br. When viewed downward, the frame portion 12b surrounds the periphery of the protrusion 12a. The protrusion 12a does not contact the frame portion 12b.

[0016] 2, the first 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 first 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 resin main body member 12 is an insulating material. The material of the first resin main body member 12 is, for example, resin.

[0017] High-frequency signals are input to and output from the first signal terminals 13a to 13j. The first signal terminals 13a to 13j are supported by the first resin body member 12. More specifically, the first signal terminals 13a to 13e are supported by the rear long side portion 12bb of the frame portion 12b. The first signal terminals 13a to 13e are lined up in a row from left to right. As a result, the first signal terminals 13a to 13e are located behind the protrusion portion 12a.

[0018] The first signal terminals 13f to 13j are supported by the front long side portion 12bf of the frame portion 12b. The first signal terminals 13f to 13j are lined up in a row from left to right. As a result, the first signal terminals 13f to 13j are located in front of the protrusion portion 12a. The first signal terminals 13f to 13j are also located in front of the first signal terminals 13a to 13e. The first signal terminals 13a to 13j are made by bending a rod-shaped metal member. The first signal terminals 13a to 13j are made of a copper-based material such as phosphor bronze.

[0019] The first ground terminals 14ra, 14rb, and 14rc are connected to the ground potential of the first connector 10. 3 Terminal, No. 4 2, the first ground terminals 14ra, 14rb, and 14rc are supported by the first resin main body member 12. The structure of the first ground terminals 14ra, 14rb, and 14rc will be described below.

[0020] The first ground terminal 14ra (first terminal) is supported by the right short side portion 12br. As shown in FIG. 2, a part of the first ground terminal 14ra is embedded in the right short side portion 12br. 3 The first ground terminal 14rb is supported by the right side of the front long side 12bf. As shown in FIG. 2, a part of the first ground terminal 14rb is embedded in the front long side 12bf. 4 The first ground terminal 14rc is supported by the right portion of the rear long side 12bb. A portion of the first ground terminal 14rc is embedded in the rear long side 12bb, as shown in FIG.

[0021] The first ground terminal 14ra (first terminal) and the first ground terminal 14rb (third terminal) are located apart from each other. The first ground terminal 14ra and the first ground terminal 14rb are not in contact with each other. There are no other terminals between the first ground terminal 14ra (first terminal) and the first ground terminal 14rb (third terminal). More specifically, there are no other terminals and the first resin body member 12 or a space is present at the portion where the first ground terminal 14ra and the first ground terminal 14rb are closest to each other. Similarly, the first ground terminal 14ra (first terminal) and the first ground terminal 14rc (fourth terminal) are located apart from each other. The first ground terminal 14ra and the first ground terminal 14rc are not in contact with each other. There are no other terminals between the first ground terminal 14ra (first terminal) and the first ground terminal 14rc (fourth terminal). More specifically, in the area where the first ground terminal 14ra and the first ground terminal 14rc are closest to each other, there is no other terminal and the first resin main body member 12 or a space is present.

[0022] The first ground terminals 141a, 141b, and 141c have a symmetrical structure to the first ground terminals 14ra, 14rb, and 14rc, and therefore a description thereof will be omitted. The first ground terminals 141a, 141b, 141c, ...

[0023] The first connector 10 as described above is mounted on a first circuit board (not shown) with the bottom surface of the first resin body member 12 facing the first circuit board. Specifically, portions of the first signal terminals 13a to 13j and portions of the first ground terminals 14la, 14lb, 14lc, 14ra, 14rb, and 14rc are exposed from the bottom surface of the first resin body member 12. Solder is then applied to each of these portions. As a result, the first signal terminals 13a to 13j and the first ground terminals 14la, 14lb, 14lc, 14ra, 14rb, and 14rc 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 resin main body member 112, second signal terminals 113a to 113j, and second ground terminals 1411a, 1141b, 1141c, 1141ra, 1141rb, and 114rc.

[0026] The second resin body member 112 includes a bottom surface portion 112a and a frame portion 112b. When viewed from above, the frame portion 112b has a rectangular ring shape with a front long side portion 112bf and a rear long side portion 112bb extending along the left-right axis, and a left short side portion 112bl and a right short side portion 112br extending along the front-rear axis. The front long side portion 112bf is located in front of the rear long side portion 112bb. The left short side portion 112bl is located to the left of the right short side portion 112br.

[0027] When viewed from above, bottom surface portion 112a covers the upper surface of the area surrounded by frame portion 112b. Second resin main body member 112 is made of an insulating material. Second resin main body member 112 is made of, for example, resin.

[0028] High-frequency signals are input to and output from the second signal terminals 113a to 113j. The second signal terminals 113a to 113j are supported by the second resin body member 112. More specifically, the second signal terminals 113a to 113e are supported by the rear long side portion 112bb. The second signal terminals 113a to 113e are lined up in a row from left to right in this order.

[0029] The second signal terminals 113f-113j are supported by the front long side portion 112bf. The second signal terminals 113f-113j are located in front of the second signal terminals 113a-113e. The second signal terminals 113f-113j are lined up in a row from left to right. The second signal terminals 113a-113j are made by bending a rod-shaped metal member. The second signal terminals 113a-113j are made of a copper-based material such as phosphor bronze.

[0030] The second ground terminals 114ra, 114rb, and 114rc are connected to the ground potential of the second connector 110. The second ground terminals 114ra, 114rb, and 114rc are supported by the second resin body member 112. The structure of the second ground terminals 114ra, 114rb, and 114rc will be described below.

[0031] The second ground terminal 114ra (second terminal) is supported by the right short side portion 112br. A portion of the second ground terminal 114ra is embedded in the right short side portion 112br, as shown in FIG. 3. The second ground terminal 114rb (fifth terminal) is supported by the right portion of the front long side portion 112bf. A portion of the second ground terminal 114rb is embedded in the front long side portion 112bf, as shown in FIG. 3. The second ground terminal 114rc (sixth terminal) is supported by the right portion of the rear long side portion 112bb. A portion of the second ground terminal 114rc is embedded in the rear long side portion 112bb, as shown in FIG. 3.

[0032] The second ground terminal 114ra and the second ground terminal 114rb are spaced apart. The second ground terminal 114ra and the second ground terminal 114rb are not in contact with each other. There are no other terminals between the second ground terminal 114ra and the second ground terminal 114rb. More specifically, there are no other terminals and the first resin body member 12 or a space is present at the portion where the second ground terminal 114ra and the second ground terminal 114rb are closest to each other. Similarly, the second ground terminal 114ra and the second ground terminal 114rc are spaced apart. The second ground terminal 114ra and the second ground terminal 114rc are not in contact with each other. There are no other terminals and the first resin body member 12 or a space is present at the portion where the second ground terminal 114ra and the second ground terminal 114rc are closest to each other. More specifically, there are no other terminals and the first resin body member 12 or a space is present at the portion where the second ground terminal 114ra and the second ground terminal 114rc are closest to each other.

[0033] The second ground terminals 114la, 114lb, and 114lc have a structure symmetrical to that of the second ground terminals 114ra, 114rb, and 114rc, and therefore will not be described here. The second ground terminals 114la, 114lb, 114lc, 114ra, 114rb, and 114rc are fabricated by bending a metal member. The second ground terminals 114la, 114lb, 114lc, 114ra, 114rb, and 114rc are made of a copper-based material such as phosphor bronze.

[0034] In the second connector 110 described above, the second connector 110 is mounted on a second circuit board (not shown) so that the upper surface of the second resin body member 112 faces the circuit board. Specifically, portions of the second signal terminals 113a-113j and the second ground terminals 114la, 114lb, 114lc, 114ra, 114rb, and 114rc are exposed from the upper surface of the second resin body member 112. Solder is then applied to each of these portions. As a result, the second signal terminals 113a-113j and the second ground terminals 114la, 114lb, 114lc, 114ra, 114rb, and 114rc are connected to electrodes of the second circuit board.

[0035] [Contact between the first ground terminals 14ra, 14rb, and 14rc and the second ground terminals 114ra, 114rb, and 114rc] The contact between the first ground terminals 14ra, 14rb, 14rc and the second ground terminals 114ra, 114rb, 114rc will be described. Fig. 4 is a perspective view of the first signal terminals 13a-13j, the second signal terminals 113a-113j, the first ground terminals 14la, 14lb, 14lc, and the second ground terminals 114ra, 114rb, 114rc. Fig. 5 is a view of the first ground terminal 14ra and the second ground terminal 114ra as viewed from the front. Fig. 6 is a view of the first ground terminal 14lb and the second ground terminal 114lb as viewed from the right.

[0036] 4, when the first connector 10 and the second connector 110 are coupled, the first signal terminals 13a to 13j come into contact with the second signal terminals 113a to 113j, respectively. Furthermore, when the first connector 10 and the second connector 110 are coupled, the first ground terminal 14ra (first terminal) comes into contact with the second ground terminal 114ra (second terminal), the first ground terminal 14rb (third terminal) comes into contact with the second ground terminal 114rb (fifth terminal), and the first ground terminal 14rc (fourth terminal) comes into contact with the second ground terminal 114rc (sixth terminal). When the first connector 10 and the second connector 110 are coupled, the first ground terminal 14la contacts the second ground terminal 114la, the first ground terminal 14lb contacts the second ground terminal 114lb, and the first ground terminal 14lc contacts the second ground terminal 114lc.

[0037] First, the connection between the first ground terminal 14ra and the second ground terminal 114ra will be described. As shown in FIG. 5, the first ground terminal 14ra has an upside-down U-shape. The first ground terminal 14ra (first terminal) includes a first portion 14raa, a second portion 14rab, and a first connecting portion 14rac. The first portion 14raa extends along the vertical axis. The second portion 14rab extends along the vertical axis. The second portion 14rab is located to the left of the first portion 14raa. Therefore, the second portion 14rab is aligned with the first portion 14raa along the horizontal axis (the axis perpendicular to the vertical axis). The first connecting portion 14rac connects the upper end of the first portion 14raa to the upper end of the second portion 14rab.

[0038] The second portion 14rab is in contact with the second ground terminal 114ra (second terminal). The lower end of the first portion 14raa is fixed by solder to the electrode 202a of the first circuit board 200. The lower end of the second portion 14rab is fixed by solder to the electrode 202b of the first circuit board 200. However, the first portion 14raa is not in contact with the second ground terminal 114ra (second terminal).

[0039] Next, the connection between the first ground terminal 14rb and the second ground terminal 114rb will be described. As shown in FIG. 6, the first ground terminal 14rb includes a first portion 14rba, a second portion 14rbb, and a first connecting portion 14rbc. The first portion 14rba extends along the vertical axis. The second portion 14rbb extends along the vertical axis. The second portion 14rbb is located behind the first portion 14rba. Therefore, the second portion 14rbb is aligned with the first portion 14rba along the front-rear axis (an axis perpendicular to the vertical axis). The first connecting portion 14rbc connects the upper end of the first portion 14rba to the upper end of the second portion 14rbb.

[0040] The second portion 14rbb is in contact with the second ground terminal 114rb. The lower end of the first portion 14rba is fixed to the electrode 202c of the first circuit board 200 by soldering. The lower end of the second portion 14rbb is fixed to the electrode 202d of the first circuit board 200 by soldering. However, the first portion 14rba is not in contact with the second ground terminal 114rb (second terminal). Note that the connection between the first ground terminal 14rc and the second ground terminal 114rc is symmetrical to the connection between the first ground terminal 14rb and the second ground terminal 114rb, and therefore a description thereof will be omitted. With the above connections, the first ground terminals 14ra, 14rb, and 14rc (first terminal, third terminal, and fourth terminal) and the second ground terminals 114ra, 114rb, and 114rc are connected to the ground potential.

[0041] [effect] The connector set 1 can prevent an LC resonant circuit caused by capacitance between the first ground terminals 14ra, 14rb, 14rc and the second ground terminals 114ra, 114rb, 114rc from affecting the transmission of high-frequency signals between the first connector 10 and the second connector 110. FIG. 7 is a top view of the first ground terminal 514r and the second ground terminal 614r of a connector set 501 according to a comparative example. FIG. 8 is a top view of the first ground terminals 14ra, 14rb, 14rc and the second ground terminals 114ra, 114rb, 114rc of the connector set 1. FIG. 9 is an equivalent circuit diagram of the connector set 501 according to the comparative example. FIG. 10 is an equivalent circuit diagram of the connector set 1.

[0042] In the connector set 501 according to the comparative example, the first ground terminal 514r has a structure in which the first ground terminals 14ra, 14rb, and 14rc are connected together. The second ground terminal 614r has a structure in which the second ground terminals 114ra, 114rb, and 114rc are connected together. In this case, the inductance value of the first ground terminal 514r is L1, the inductance value of the second ground terminal 614r is L2, and the capacitance values ​​generated between the first ground terminal 514r and the second ground terminal 614r are C0a to C0c. In this case, the resonant frequency f0 of the LC resonant circuit caused by the capacitance between the first ground terminal 514r and the second ground terminal 614r is 1 / (2π√(L1+L2)·C0), where C0=C0a+C0b+C0c.

[0043] On one hand, let the inductance value of the first ground terminal 14ra be L1a, the inductance value of the second ground terminal 114ra be L2a, and the capacitance value generated between the first ground terminal 14ra and the second ground terminal 114ra be C0a. Also, let the inductance value of the first ground terminal 14rb be L1b, the inductance value of the second ground terminal 114rb be L2b, and the capacitance value generated between the first ground terminal 14rb and the second ground terminal 114rb be C0b. Let the inductance value of the first ground terminal 14rc be L1c, the inductance value of the second ground terminal 114rc be L2c, and the capacitance value generated between the first ground terminal 14rc and the second ground terminal 114rc be C0c.

[0044] At this time, the resonance frequency fa of the LC resonance circuit due to the capacitance between the first ground terminal 14ra and the second ground terminal 114ra is 1 / (2π√(L1a + L2a)·C0a). The resonance frequency fb of the LC resonance circuit due to the capacitance between the first ground terminal 14rb and the second ground terminal 114rb is 1 / (2π√(L1b + L2b)·C0b). The resonance frequency fc of the LC resonance circuit due to the capacitance between the first ground terminal 14rc and the second ground terminal 114rc is 1 / (2π√(L1c + L2c)·C0c).

[0045] However, L1 > L1a, L1 > L1b, L1 > L1c, L2 > L2a, L2 > L2b, L2 > L2c hold. Also, C0 > C0a, C0 > C0b, C0 > C0c hold. Therefore, f1 < fa, f1 < fb, f1 < fc hold. As a result, in the connector set 1, the resonance frequencies of the three LC resonance circuits are outside 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 influence of the LC resonance circuit caused by the capacitance between the first ground terminals 14ra, 14rb, 14rc and the second ground terminals 114ra, 114rb, 114rc on the transmission of the high-frequency signal between the first connector 10 and the second connector 110.

[0046] Furthermore, the connector set 1 can also prevent the LC resonant circuit caused by the capacitance between the first ground terminal 14ra and the second ground terminal 114ra from affecting the transmission of high-frequency signals between the first connector 10 and the second connector 110 for the following reasons. More specifically, as shown in FIG. 5 , the second portion 14rab is in contact with the second ground terminal 114ra. The lower end of the second portion 14rab is fixed to the electrode 202b of the first circuit board 200 by soldering. As a result, the length of the current path from the second ground terminal 114ra to the electrode 202b is the distance from the contact portion P of the second portion 14rab to the lower end of the second portion 14rab. Therefore, the current path from the second ground terminal 114ra to the electrode 202b is short. As a result, the inductance value generated in the current path from the second ground terminal 114ra to the electrode 202b is reduced. Therefore, the resonant frequency of the LC resonant circuit caused by the capacitance between the first ground terminal 14ra and the second ground terminal 114ra is increased. As a result, the resonant frequency of the LC resonant circuit is outside the band of the high-frequency signals transmitted through the first connector 10 and the second connector 110. As described above, the connector set 1 can prevent the LC resonant circuit, which is caused by the capacitance between the first ground terminal 14ra and the second ground terminal 114ra, from affecting the transmission of high-frequency signals between the first connector 10 and the second connector 110.

[0047] (Variation) A connector set 1a according to a modified example will be described below with reference to the drawings. Figure 11 is a view of the first ground terminal 14ra and the second ground terminal 114ra of the connector set 1a as viewed from the front.

[0048] The connector set 1a differs from the connector set 1a in the shape of the second ground terminal 114ra. More specifically, the second ground terminal 114ra includes a third portion 114raa, a fourth portion 114rab, and a second connecting portion 114rac. The third portion 114raa extends along the vertical axis. The fourth portion 114rab extends along the vertical axis. The fourth portion 114rab is aligned with the third portion 114raa along an axis perpendicular to the vertical axis.
