Summary of the Invention

Problems to be Solved by the Invention

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

[0013] As shown in FIG. 2, the first connector 10 includes a first resin body member 12, first signal terminals 13a to 13v, and first ground terminals 14l and 14r.

[0014] As shown in FIG. 2, the first resin body member 12 includes a protrusion 12a, a frame portion 12b, and a connecting portion 12c.

[0015] When viewed from below, the frame portion 12b has an annular shape surrounding the periphery of the protruding portion 12a. The frame portion 12b has a rectangular inner edge and a rectangular outer edge when viewed from below. Accordingly, the frame portion 12b has a front side and a rear side extending along the left - right axis and a left side and a right side extending along the front - rear axis.

In the present embodiment, the connecting portion 12c connects the lower part of the protruding portion 12a and the lower part of the frame portion 12b. The material of the first resin body member 12 is an insulating material. The material of the first resin body member 12 is, for example, resin.

[0017] 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 resin body member 12. More specifically, a part of the first signal terminals 13a to 13k is embedded in the rear side of the frame portion 12b. Thereby, the first signal terminals 13a to 13k are supported by the frame portion 12b so as to be arranged along the left - right axis in the region behind the protruding portion 12a. The first signal terminals 13a to 13k are arranged in a row in this order from left to right. A part of the first signal terminals 13l to 13v is embedded in the front side of the frame portion 12b.

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 arranged in a row in this order from left to right. The first signal terminals 13l to 13v are manufactured by bending a rod - shaped metal member. The material of the first signal terminals 13l to 13v is, for example, a copper - based material such as phosphor bronze.

[0018] The first ground terminal 14r is connected to the ground potential. The first ground terminal 14r (the first terminal) is supported by the first resin body member 12 as shown in FIG. 2.

A part of the first ground terminal rear portion 14rc is embedded in the rear side of the frame portion 12b.

[0020] Since the first ground terminal 14l has a structure symmetric to that of the first ground terminal 14r, its description will be omitted. The first ground terminal 14l is manufactured by bending a metal member. The material of the first ground terminal 14l is, for example, a copper-based material such as phosphor bronze.

[0021] In the first connector 10 as described above, the first connector 10 is mounted on a first circuit board (not shown) such that the lower surface of the first resin body member 12 faces the first circuit board. Specifically, a part of the first signal terminals 13a to 13v and a part of the first ground terminals 14l and 14r are exposed from the bottom surface of the first resin body member 12. Therefore, solder is applied to each of these portions. Thereby, each of the first signal terminals 13a to 13v and the first ground terminals 14l and 14r is connected to the electrode of the first circuit board.

[0022] [Structure of the Second Connector] Next, the structure of the second connector 110 will be described. FIG. 4 is a perspective view of the second connector 110.

[0023] As shown in FIG. 4, the second connector 110 includes a second resin body member 112, second signal terminals 113a to 113v, and third ground terminals 114l and 114r.

[0024] The second resin body member 112 includes a bottom surface portion 112a and a frame portion 112b. The frame portion 112b has an annular 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 along the left - right axis and two short sides extending in the front - rear direction when viewed from above. The bottom surface portion 112a closes the upper surface of the region surrounded by the frame portion 112b as shown in FIG. 4. The material of the second resin body member 112 is an insulating material. The material of the second resin body member 112 is, for example, resin.

[0025] High - frequency signals are input and output to and from the second signal terminals 113a to 113v. The second signal terminals 113a to 113v are supported by the second resin body member 112. More specifically, a part of the second signal terminals 113a to 113k is embedded in the rear side of the frame portion 112b. The second signal terminals 113a to 113k are arranged in a row in this order from left to right. A part of the second signal terminals 113l to 113v is embedded in the front side 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 arranged in a row in this order from left to right. The second signal terminals 113a to 113v are manufactured by bending a rod - shaped metal member. The material of the second signal terminals 113a to 113v is, for example, a copper - based material such as phosphor bronze.

[0026] The third ground terminal 114r is connected to the ground potential. The third ground terminal 114r (the second terminal) is supported by the second resin body member 112. Specifically, the third ground terminal 114r is supported by the right side, the front side, and the rear side of the frame portion 112b. Hereinafter, the structure of the third ground terminal 114r will be described.

[0027] As shown in FIG. 4, the third ground terminal 114r includes a third ground terminal main body portion 114ra, a third ground terminal front portion 114rb, and a third ground terminal rear portion 114rc. The third ground terminal main body portion 114ra is provided on the left surface, the upper surface, and the right surface of the right side of the frame portion 12b. A part of the third ground terminal main body portion 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 surface, the upper surface, and the rear surface of the right end portion of the front side of the frame portion 112b. A part 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 surface, the upper surface, and the rear surface of the right end portion of the rear side of the frame portion 112b. A part of the third ground terminal rear portion 114rc is embedded in the rear side of the frame portion 112b.

[0028] Since the structure of the third ground terminal 114l is symmetric to the structure of the third ground terminal 114r with respect to left and right, the description thereof will be omitted. The third ground terminals 114l and 114r are manufactured by bending a metal member. The material of the third ground terminals 114l and 114r is, for example, a copper-based material such as phosphor bronze.

[0029] 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 resin body member 112 faces the circuit board. Specifically, a part of the second signal terminals 113a to 113v and the third ground terminals 114l and 114r is exposed from the bottom surface of the second resin body member 112. Therefore, solder is applied to each of these portions. Thereby, each of the second signal terminals 113a to 113v and the third ground terminals 114l and 114r is connected to the electrode of the second circuit board.

[0030] [Contact between the first ground terminal 14r and the third ground terminal 114r] Here, the contact between the first ground terminal 14r and the third ground terminal 114r will be described. FIG. 5 is a cross-sectional view orthogonal to the front-rear axis of the first ground terminal 14r and the third ground terminal 114r. FIG. 6 is a cross-sectional view orthogonal to the up-down axis of the first ground terminal 14r and the third ground terminal 114r. FIG. 7 is a view showing the contact area A0.

[0031] As shown in FIG. 2, a first recess G1 is provided in the first ground terminal 14r. As shown in FIG. 4, a second recess G2 is provided in the third ground terminal 114r. More specifically, the left surface of the first ground terminal main body portion 14ra faces the right surface of the third ground terminal main body portion 114ra. And a first recess G1 is provided on the left surface of the first ground terminal main body portion 14ra. A second recess G2 is provided on the right surface of the third ground terminal main body portion 114ra. When viewed from the left direction, the first recess G1 and the second recess G2 overlap. The width W1 in the direction along the front-rear axis (the second direction) of the first recess G1 is larger than the width W2 in the direction along the front-rear axis (the second direction) of the second recess G2. Also, the height H1 in the direction along the up-down axis (the first direction) of the first recess G1 is larger than the height H2 in the direction along the up-down axis (the first direction) of the second recess G2.

[0032] As a result, the first ground terminal 14r (first terminal) and the third ground terminal 114r (second terminal) are in contact with each other in a contact region A0 including a first contact region A1, a second contact region A2, a third contact region A3, a fourth contact region A4, a fifth contact region A5, a sixth contact region A6, a seventh contact region A7, and an eighth contact region A8, as shown in FIGS. 5 to 7. The first ground terminal 14r (first terminal) and the third ground terminal 114r (second terminal) are not in contact with each other in a non-contact region A10. Thus, in the non-contact region A10, a first recess G1 is provided in the first ground terminal 14r (first terminal). In the non-contact region A10, a second recess G2 is provided in the third ground terminal 114r (second terminal). Also, the third ground terminal 114r (second terminal) is not located within the first recess G1. Also, the first ground terminal 14r (first terminal) is not located within the second recess G2.

[0033] The first contact region A1, the non-contact region A10, and the second contact region A2 are arranged in a row in the downward direction (first direction) in this order. The first contact region A1 is located above the non-contact region A10. The first contact region A1 is in contact with the non-contact region A10. The second contact region A2 is located below the non-contact region A10. The second contact region A2 is in contact with the non-contact region A10.

[0034] The third contact region A3, the non-contact region A10, and the fourth contact region A4 are arranged in a row in the rearward direction (second direction) in this order. The rearward direction (second direction) is orthogonal to the downward direction (first direction). The third contact region A3 is located in front of the non-contact region A10. The third contact region A3 is in contact with the non-contact region A10. The fourth contact region A4 is located behind the non-contact region A10. The fourth contact region A4 is in contact with the non-contact region A10.

[0035] Further, a fifth contact area A5 is located above and in front of the non-contact area A10. A sixth contact area A6 is located above and behind the non-contact area A10. A seventh contact area A7 is located below and in front of the non-contact area A10. An eighth contact area A8 is located below and behind the non-contact area A10. As a result, the contact area A0 has an annular shape. And the non-contact area A10 is surrounded by the first contact area A1 to the eighth contact area A8.

[0036] Note that the contact between the first ground terminal 14l and the third ground terminal 114l is the same as the contact between the first ground terminal 14r and the third ground terminal 114r, so the description thereof is omitted.

[0037] [Effect] 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 terminal 14r and the third ground terminal 114r on the transmission of high-frequency signals between the first connector 10 and the second connector 110. More specifically, in the non-contact region A10, a first recess G1 is provided in the first ground terminal 14r. In the non-contact region A10, a second recess G2 is provided in the third ground terminal 114r. As a result, as shown in FIGS. 5 to 7, the first ground terminal 14r and the third ground terminal 114r are in contact with each other in the contact region A0 including the first contact region A1, the second contact region A2, the third contact region A3, the fourth contact region A4, the fifth contact region A5, the sixth contact region A6, the seventh contact region A7, and the eighth contact region A8. The first ground terminal 14r and the third ground terminal 114r are not in contact with each other in the non-contact region A10. Thereby, in the non-contact region A10, the distance between the first ground terminal 14r and the third ground terminal 114r becomes large, so the capacitance formed between the first ground terminal 14r and the third ground terminal 114r becomes small. Therefore, the resonance frequency of the LC resonance circuit becomes high. 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 influence of the LC resonance circuit caused by the capacitance between the first ground terminal 14r and the third ground terminal 114r on the transmission of high-frequency signals between the first connector 10 and the second connector 110.

[0038] Also, according to the connector set 1, even if the attachment and detachment between the first connector 10 and the second connector 110 are repeated, the distance between the first ground terminal 14r and the third ground terminal 114r hardly changes. FIG. 8 is a diagram showing the first ground terminal 214 and the third ground terminal 314 according to the comparative example. FIG. 9 is a diagram showing the first ground terminal 14r and the third ground terminal 114r.

[0039] In the case of the first ground terminal 214 and the third ground terminal 314 according to the comparative example, when the attachment and detachment of the two connectors are repeated, the first ground terminal 214 and the third ground terminal 314 are worn. As a result, as shown in FIG. 8, the distances from the first ground terminal 214 and the third ground terminal 314 are likely to vary. On the other hand, even if the first ground terminal 14r and the third ground terminal 114r are worn, as shown in FIG. 9, the distance between the first ground terminal 14r and the third ground terminal 114r is unlikely to change. Accordingly, in the non-contact region A10, since the distance between the first ground terminal 14r and the third ground terminal 114r is maintained, the capacitance formed between the first ground terminal 14r and the third ground terminal 114r is unlikely to decrease.

[0040] (First Modified Example) Hereinafter, the connector set 1a according to the first modified example will be described with reference to the drawings. FIG. 10 is a cross-sectional view perpendicular to the longitudinal axis of the first ground terminal 14r and the third ground terminal 114r of the connector set 1a.

[0041] The connector set 1a is different from the connector set 1 in that the first ground terminal 14r is provided with a first recess G1 and the third ground terminal 114r is not provided with a second recess G2. Since the other structures of the connector set 1a are the same as those of the connector set 1, the description thereof will be omitted. The connector set 1a can achieve the same effects as the connector set 1.

Since the other structures of the connector set 1b are the same as those of the connector set 1, the description thereof is omitted. The connector set 1b can achieve the same effects as the connector set 1.

[0044] (Third modification example) Hereinafter, the connector set 1c according to the third modification example will be described with reference to the drawings. FIG. 12 is a cross-sectional view perpendicular to the front-rear axis of the first ground terminal 14r and the third ground terminal 114r of the connector set 1c.

[0045] The connector set 1c is different from the connector set 1 in that in the non-contact region A10, the first ground terminal 14r is provided with the first through hole h1, and the third ground terminal 114r is provided with the second through hole h2. Since the other structures of the connector set 1c are the same as those of the connector set 1, the description thereof is omitted. The connector set 1c can achieve the same effects as the connector set 1.

[0046] (Fourth modification example) Hereinafter, the connector set 1d according to the fourth modification example will be described with reference to the drawings. FIG. 13 is a view showing the contact region A0 of the connector set 1d.

[0047] The connector set 1d is different from the connector set 1 in that the third contact region A3 and the fourth contact region A4 do not exist. Since the other structures of the connector set 1d are the same as those of the connector set 1, the description thereof is omitted. The connector set 1d can achieve the same effects as the connector set 1.

[0048] (Other embodiments) The connector set according to the present invention is not limited to the connector sets 1, 1a to 1d, and can be changed within the scope of the gist thereof. Also, the structures of the connector sets 1, 1a to 1d may be arbitrarily combined.

[0049] Note that the first terminal may be the first signal terminals 13a to 13v, and the second terminal may be the second signal terminals 113a to 113v.

[0050] 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.
