Description

The present invention relates to a connector set having a first connector and a second connector.

As an example of a conventional invention related to a connector set, a plug connector and a receptacle connector are known, as described in Patent Document 1. The plug connector has a first ground terminal. The receptacle connector has a second ground terminal. The plug connector and the receptacle connector are coupled to each other. At this time, the first ground terminal and the second ground terminal are in surface contact. This electrically connects the first ground terminal and the second ground terminal.

JP 2006-331679 A

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 surface of the first ground terminal and the surface of 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, a 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 the 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.

The object of the present invention is to provide a connector set that can suppress the influence of an LC resonant circuit caused by the capacitance between the first ground terminal and the second ground terminal on the transmission of high-frequency signals between the first connector and the second connector.

In the second connector 110 as described above, the second connector 110 is mounted on a second circuit board (not shown) so that the top surface of the second body member 112 faces the circuit board. Specifically, a portion of the second signal terminals 113a-113v, a portion of the third ground terminal 114r, and a portion of the fourth ground terminal 114l are exposed from the bottom surface of the second body member 112. Solder is then applied to each of these portions. As a result, the second signal terminals 113a-113v, the third ground terminal 114r, and the fourth ground terminal 114l are each connected to an electrode of the second circuit board.

[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.

As shown in FIG. 4, the first signal terminals 13a to 13v are in contact with the second signal terminals 113a to 113v, respectively. The fifth ground terminals 16ra and 16rb are in contact with the third ground terminal 114r while undergoing elastic deformation. The sixth ground terminals 16la and 16lb are in contact with the fourth ground terminal 114la while undergoing elastic deformation.

The first ground terminal 14r and the third ground terminal 114r may or may not be in contact with each other. In this embodiment, the first ground terminal 14r and the third ground terminal 114r are not in contact with each other.

As shown in FIG. 5, the first ground terminal 14r includes a first portion 14raa extending in the up-down 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 side 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 main body member 12. The second main surface and the two first side surfaces of the first portion 14raa are embedded in the first main body member 12, so that the first portion 14raa is held by the first main body member 12. As a result, the first portion 14raa cannot be elastically deformed.

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 portion 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, so that the second portion 114raa is held by the second main body member 112. This prevents the second portion 114raa from elastically deforming.

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. Since the first portion 14raa or the second portion 114raa is inclined in the vertical direction, the space Sp1 becomes larger from bottom to top. In this embodiment, the first portion 14raa is inclined in 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 inclined in the vertical direction. However, as described below, the first portion 14raa is not in contact with the second portion 114raa.

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.

As shown in FIG. 5, the first ground terminal 14r includes a first portion 14rda extending in the up-down 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 portion 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 body member 12. The second main surface and the two first side surfaces of the first portion 14rda are embedded in the first body member 12, so that the first portion 14rda is held by the first body member 12. As a result, the first portion 14rda cannot be elastically deformed.

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 side 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, so that the second portion 114rab is held by the second main body member 112. This prevents the second portion 114rab from elastically deforming.

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

The right end of the protrusion 12a of the first main body member 12 comes into contact with the second portion 114rab, so that the first portion 14rda and the second portion 114rba face each other, and a space Sp2 exists between the first portion 14rda and the second portion 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 to the right. The first surface S11 is located to the right of the first portion 14rda. The first surface S11 comes into contact with the second portion 114rab. As a result, the first portion 14rda is not in contact with the second portion 114rab.

As shown in FIG. 6, the first ground terminal 14r includes a first portion 14rba extending in the up-down direction. The first portion 14rba is a part of the first ground terminal front portion 14rb. The first portion 14rba is exposed from the rear surface of the front edge of the frame portion 12b. More specifically, the first portion 14rba 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 14rba are embedded in the first body member 12, so that the first portion 14rba is held by the first body member 12. This prevents the first portion 14rba from elastically deforming.

As shown in FIG. 6, the third ground terminal 114r includes a second portion 114rba extending in the up-down direction. The second portion 114rba is a part of the third ground terminal front portion 114rb. The second portion 114rba is exposed from the front surface of the front edge 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 body member 112. The fourth main surface and the two second side surfaces of the second portion 114rba are embedded in the second body member 112, so that the second portion 114rba is held by the second body member 112. This prevents the second portion 114rba from elastically deforming.

Here, the first portion 14rba and the second portion 114rba face each other. As a result, 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. Since the first portion 14rba or the second portion 114rba is inclined in the vertical direction, the space Sp3 becomes larger from bottom to top. In this embodiment, the first portion 14rba is inclined in 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 described below, the first portion 14rba is not in contact with the second portion 114rba.

The front edge of the frame portion 12b of the first main body member 12 contacts the second portion 114rba, so that 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 edge of the frame portion 12b of the first main body member 12 has a first surface S21. The first surface S21 faces in the rear direction. The first surface S21 is located behind the first portion 14rba. The first surface S21 contacts the second portion 114rba. As a result, the first portion 14rba is not in contact with the second portion 114rba.

The first ground terminal rear portion 14rc and the third ground terminal rear portion 114rc have a structure that is symmetrical from front to back with the first ground terminal front portion 14rb and the third ground terminal front portion 114rb, so a description thereof will be omitted. Also, the second ground terminal 14l and the fourth ground terminal 114l have a structure that is symmetrical from left to right with the first ground terminal 14r and the third ground terminal 114r, so a description thereof will be omitted.

[effect]
According to the connector set 1, it is possible to suppress the LC resonant 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, 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. 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 resonant frequency of the LC resonant circuit becomes high. As a result, the resonant frequency of the LC resonant circuit is out of 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 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.

The connector set 1 can also suppress the LC resonant 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 for the following reasons. More specifically, 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 as shown in FIG. 5. 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 from bottom to top. As a result, the distance between the first portion 14raa and the second portion 114raa increases, and the capacitance formed between the first ground terminal 14r and the third ground terminal 114r decreases. This increases the resonant frequency of the LC resonant circuit. This causes the resonant frequency of the LC resonant circuit to deviate from the band of the high-frequency signal transmitted through the first connector 10 and the second connector 110. As described above, the connector set 1 can suppress the LC resonant 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.

The first portion 14raa cannot be elastically deformed because it is held by the first body member 12. The second portion 114raa cannot be elastically deformed because it is held by the second body member 112. Therefore, depending on the state in which the first connector 10 and the second connector 110 are connected, the first portion 14raa and the second portion 114raa may or may not be in contact. In this embodiment, the first portion 14raa is not in contact with the second portion 114raa. Therefore, the fifth ground terminals 16ra and 16rb contact the third ground terminal 114r while elastically deforming. This allows the fifth ground terminals 16ra and 16rb to more reliably contact the third ground terminal 114r.

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, an LC resonant circuit caused by the capacitance between the first ground terminal 14r and the third ground terminal 114r is likely to affect the transmission of high-frequency signals between the first connector 10 and the second connector 110. Therefore, in the connector set 1, the first portion 14raa is inclined in the vertical direction, so that the space Sp1 becomes larger from bottom to top. This makes it possible to suppress the LC resonant 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.

(Modification)
A connector set 1a according to a modified example will be described below with reference to the drawings. Fig. 7 is a cross-sectional view of the connector set 1a.

The connector set 1a differs 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 rightward direction. The first ground terminal 14r further includes a first portion 14raa (third portion) located to the right (first direction) of the first portion 14rda. The third ground terminal 114r further includes a second portion 114raa (fourth portion) located to the right (first direction) of the second portion 114rab. The second portion 114rab is pushed to the right (first direction) by the first body member 12, so that the second portion 114raa (fourth portion) is pressed against the first portion 14raa (third portion). The rest of the structure of connector set 1a is the same as connector set 1, so a detailed explanation will be omitted. Connector set 1a can achieve the same effects as connector set 1.

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.
