[0009] [First embodiment] A connector set 1 including a first connector 10 according to a first embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a perspective view of the connector set 1 according to the first embodiment.

[0010] In this specification, directions are defined as follows. As shown in FIG. 1 , the direction from the second connector 110 to the first connector 10 is defined as the downward direction. The opposite direction of the downward direction is defined as the upward direction. As shown in FIG. 2 , the direction in which the first signal terminals 15l are arranged in the first connector 10 is defined as the forward direction. The opposite direction of the forward direction is defined as the rearward direction. The front-rear axis is perpendicular to the up-down axis. An axis perpendicular to the up-down axis and the front-rear axis is defined as the left-right axis. However, the up-down axis, front-rear axis, and left-right axis in this specification are defined for the convenience of explanation and may not coincide with the up-down axis, front-rear axis, and left-right axis when the connector set 1 is in use. Furthermore, in each drawing, the upward direction and the downward direction may be interchanged, the left direction and the right direction may be interchanged, and the front direction and the rear direction may be interchanged.

[0011] In this specification, the positional relationship of the members is defined as follows: The first member to the third member constitute the connector set 1. In this specification, the phrase "the first member is disposed above the second member" refers to the following state: At least a portion of the first member is located directly above the second member. Therefore, when viewed from below, the first member overlaps with the second member. This definition also applies to directions other than the upward direction.

[0012] In this specification, "a first member being positioned above a second member" includes a case where at least a portion of the first member is positioned directly above the second member, and a case where the first member is not positioned directly above the second member but is positioned diagonally above the second member. In this case, the first member does not have to overlap with the second member when viewed from below. "Diagonally above" refers to, for example, the upper left or upper right. This definition also applies to directions other than the upward direction.

[0013] In this specification, unless otherwise specified, the various parts of the first member are defined as follows: The front part of the first member means the front half of the first member. The front end of the first member means the front end of the first member. The front end part of the first member means the front end of the first member and its vicinity. These definitions also apply to directions other than the front direction.

[0014] When any two members in this specification are defined as a first member and a second member, the relationship between any two members has the following meaning. In this specification, "a first member is supported by a second member" includes both a case where the first member is attached to the second member so as to be immovable relative to the second member (i.e., fixed), and a case where the first member is attached to the second member so as to be movable relative to the second member. Furthermore, "a first member is supported by a second member" includes both a case where the first member is attached directly to the second member and a case where the first member is attached to the second member via a third member.

[0015] In this specification, "a first member is held by a second member" includes a case where the first member is attached to the second member so as to be immovable relative to the second member (i.e., fixed), but does not include a case where the first member is attached to the second member so as to be movable relative to the second member. Furthermore, "a first member is held by a second member" includes both a case where the first member is directly attached to the second member and a case where the first member is attached to the second member via a third member.

[0016] In this specification, "the first member and the second member are electrically connected" means that electricity is conducted between the first member and the second member. Therefore, the first member and the second member may be in contact with each other, or may not be in contact with each other. When the first member and the second member are not in contact with each other, a third member having electrical conductivity is disposed between the first member and the second member.

[0017] In this specification, an axis or member extending in the vertical direction refers to an axis or member inclined within a range of ±45° with respect to the vertical direction. Similarly, an axis or member extending in the front-rear direction does not necessarily refer only to an axis or member that is parallel to the front-rear direction. An axis or member extending in the front-rear direction refers to an axis or member inclined within a range of ±45° with respect to the front-rear direction. An axis or member extending in the left-right direction refers to an axis or member inclined within a range of ±45° with respect to the left-right direction.

[0018] 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 mated, the first connector 10 is located below the second connector 110.

[0019] [Structure of First Connector] Next, the structure of the first connector 10 will be described with reference to the drawings. Fig. 2 is a perspective view of the first connector 10 according to the first embodiment. Fig. 3 is a perspective view of the first signal terminals 15l, 15r and the first ground terminals 16b1 to 16b3, 16f1 to 16f3 of the first connector 10 according to the first embodiment.

[0020] 2 and 3, the first connector 10 includes a resin body member 11, first signal terminals 15l and 15r, and first ground terminals 16b1 to 16b3 and 16f1 to 16f3. The resin body member 11, the first signal terminals 15l and 15r, and the first ground terminals 16b1 to 16b3 and 16f1 to 16f3 are integrally molded by insert molding. The first signal terminals 15l and 15r and the first ground terminals 16b1 to 16b3 and 16f1 to 16f3 correspond to "first external connection terminals."

[0021] As shown in FIG. 2 , the resin body member 11 includes a bottom surface portion 11a and a frame portion 11b. The frame portion 11b has a ring shape when viewed from below. More specifically, the frame portion 11b has a rectangular outer edge and a rectangular inner edge when viewed from below. When viewed from below, the outer edge and the inner edge of the frame portion 11b each have left and right sides extending along the front-to-rear axis and front and rear sides extending along the left-to-right axis. When viewed from below, the bottom surface portion 11a covers the lower surface of the area surrounded by the frame portion 11b. The material of the resin body member 11 is an insulating material. The material of the resin body member 11 is, for example, resin.

[0022] High-frequency signals are input to and output from the first signal terminals 15l and 15r. The first signal terminals 15l and 15r are supported by the resin body member 11. More specifically, a portion of the first signal terminal 15l is embedded in the left side of the frame portion 11b. The first signal terminals 15l are aligned in a line along the front-rear axis. The resin body member 11 is present between adjacent first signal terminals 15l. Furthermore, a portion of the first signal terminals 15r is embedded in the right side of the frame portion 11b. The first signal terminals 15r are aligned in a line along the front-rear axis. The resin body member 11 is present between adjacent first signal terminals 15r. The first signal terminals 15l and 15r are fabricated by bending a rod-shaped metal member. The material of the first signal terminals 15l and 15r is, for example, a copper-based material such as phosphor bronze.

[0023] The structures of the first signal terminals 15l and 15r will be described in detail with reference to the drawings. The first signal terminal 15l has a structure symmetrical to that of the first signal terminal 15r, and therefore will not be described here. Fig. 4 is a perspective view of the first signal terminal 15r according to the first embodiment. Fig. 5 is a cross-sectional view of the first signal terminal 15r and the frame portion 11b according to the first embodiment.

[0024] 4 and 5, the first signal terminal 15r includes a main body portion MBa and an exposed portion PE. The main body portion MBa has a first portion P1a, a second portion P2a, a third portion P3a, a first connecting portion PC1a, and a second connecting portion PC2a.

[0025] The first portion P1a has a first left surface SL1a facing leftward, a first right surface SR1a facing rightward, a first rear surface SB1a and a first front surface SF1a aligned in the front-to-rear direction, and a first bottom surface SD1a facing downward. The first left surface SL1a is not in contact with the resin body member 11. Therefore, the first left surface SL1a is exposed from the resin body member 11. The first right surface SR1a, the first rear surface SB1a, the first front surface SF1a, and the first bottom surface SD1a are in contact with the frame portion 11b. Therefore, the first right surface SR1a, the first rear surface SB1a, the first front surface SF1a, and the first bottom surface SD1a are in contact with the resin body member 11. The first portion P1a extends in the up-down direction. In this embodiment, the length of the first portion P1a in the left-to-right direction is uniform.

[0026] The second portion P2a is located above the first portion P1a. The second portion P2a has a second rear surface SB2a and a second front surface SF2a aligned in the front-rear direction, a first upper surface SU1a facing upward, and a second lower surface SD2a facing downward. The first upper surface SU1a is not in contact with the resin body member 11. Therefore, the first upper surface SU1a is exposed from the resin body member 11. The second rear surface SB2a, the second front surface SF2a, and the second lower surface SD2a are in contact with the frame portion 11b. Therefore, the second rear surface SB2a, the second front surface SF2a, and the second lower surface SD2a are in contact with the resin body member 11. The second portion P2a extends in the left-right direction. In this embodiment, the length of the second portion P2a in the up-down direction is uniform.

[0027] The third portion P3a is located below the second portion P2a. The third portion P3a has a second left surface SL2a facing leftward, a second right surface SR2a facing rightward, and a third rear surface SB3a and a third front surface SF3a aligned in the front-to-rear direction. The second right surface SR2a is not in contact with the resin body member 11. Therefore, the second right surface SR2a is exposed from the resin body member 11. The second left surface SL2a, the third rear surface SB3a, the third front surface SF3a, and the second lower surface SD2a are in contact with the frame portion 11b. Therefore, the second left surface SL2a, the third rear surface SB3a, the third front surface SF3a, and the second lower surface SD2a are in contact with the resin body member 11. The third portion P3a extends in the up-down direction. In this embodiment, the length of the third portion P3a in the left-to-right direction is uniform.

[0028] The first connecting portion PC1a physically connects the upper end of the first portion P1a and the left end of the second portion P2a and is curved. The first connecting portion PC1a has a first inner peripheral surface IS1a facing downward and right, a first outer peripheral surface OS1a facing upward and left, and a third rear surface SB3a and a third front surface SF3a aligned in the front-to-rear direction. The first inner peripheral surface IS1a is connected to the first right surface SR1a and the second lower surface SD2a. The first outer peripheral surface OS1a is connected to the first left surface SL1a and the first upper surface SU1a. The third rear surface SB3a is connected to the first rear surface SB1a and the second rear surface SB2a. The third front surface SF3a is connected to the first front surface SF1a and the second front surface SF2a. The first outer peripheral surface OS1a does not contact the resin body member 11. Therefore, the first outer peripheral surface OS1a is exposed from the resin body member 11. The first inner peripheral surface IS1a, the third rear surface SB3a, and the third front surface SF3a are in contact with the frame portion 11b. Therefore, the first inner peripheral surface IS1a, the third rear surface SB3a, and the third front surface SF3a are in contact with the resin body member 11.

[0029] The second connecting portion PC2a physically connects the right end of the second portion P2a and the upper end of the third portion P3a and is curved. The second connecting portion PC2a has a second inner peripheral surface IS2a facing downward and left, a second outer peripheral surface OS2a facing upward and right, and a fourth rear surface SB4a and a fourth front surface SF4a aligned in the front-to-rear direction. The second inner peripheral surface IS2a is connected to the second lower surface SD2a and the second left surface SL2a. The second outer peripheral surface OS2a is connected to the first upper surface SU1a and the second right surface SR2a. The fourth rear surface SB4a is connected to the second rear surface SB2a and the third rear surface SB3a. The fourth front surface SF4a is connected to the second front surface SF2a and the third front surface SF3a. The second outer peripheral surface OS2a does not contact the resin body member 11. Therefore, the second outer peripheral surface OS2a is exposed from the resin body member 11. The second inner peripheral surface IS2a, the fourth rear surface SB4a, and the fourth front surface SF4a are in contact with the frame portion 11b. Therefore, the second inner peripheral surface IS2a, the fourth rear surface SB4a, and the fourth front surface SF4a are in contact with the resin body member 11.

[0030] In this embodiment, as shown in FIG. 4 , the first connecting portion PC1a is provided with a first chamfered portion R1a and a second chamfered portion R2a. The second connecting portion PC2a is provided with a third chamfered portion R3a and a fourth chamfered portion R4a. The second chamfered portion R2a has a front-to-back symmetrical structure with the first chamfered portion R1a. The fourth chamfered portion R4a has a front-to-back symmetrical structure with the third chamfered portion R3a. In this embodiment, the first chamfered portion R1a, the second chamfered portion R2a, the third chamfered portion R3a, and the fourth chamfered portion R4a are not connected to one another. The chamfered portions have shapes such as a flat surface connected by removing the corners, a convex surface connected by removing the corners, or a concave surface connected by removing the corners.

[0031] The third rear surface SB3a is connected to the first inner peripheral surface IS1a via the first chamfered portion R1a. More specifically, the first chamfered portion R1a is recessed toward the left in the front-rear direction. The first chamfered portion R1a is also recessed toward the front in the left-right direction. Therefore, as shown in FIG. 5, the first chamfered portion R1a is recessed from the first inner peripheral surface IS1a toward the first outer peripheral surface OS1a in the front-rear direction. However, as shown in FIG. 4, the first chamfered portion R1a does not reach the third front surface SF3a. The provision of the first chamfered portion R1a reduces the thickness of the rear end of the first connecting portion PC1a. The first chamfered portion R1a contacts the frame portion 11b. Therefore, the first chamfered portion R1a contacts the resin main body member 11.

[0032] The third front surface SF3a is connected to the first inner peripheral surface IS1a via the second chamfered portion R2a. More specifically, the second chamfered portion R2a is recessed toward the left in the front-rear direction. The second chamfered portion R2a is also recessed toward the rear in the left-right direction. Therefore, as shown in FIG. 5, the second chamfered portion R2a is recessed from the first inner peripheral surface IS1a toward the first outer peripheral surface OS1a in the front-rear direction. However, as shown in FIG. 4, the second chamfered portion R2a does not reach the third rear surface SB3a. The provision of the second chamfered portion R2a reduces the thickness of the front end of the first connecting portion PC1a. The second chamfered portion R2a contacts the frame portion 11b. Therefore, the second chamfered portion R2a contacts the resin main body member 11.

[0033] The fourth rear surface SB4a is connected to the second inner peripheral surface IS2a via a third chamfered portion R3a. More specifically, the third chamfered portion R3a is recessed to the right in a front-to-rear view. The third chamfered portion R3a is also recessed to the front in a left-right view. Therefore, as shown in FIG. 5, the third chamfered portion R3a is recessed from the second inner peripheral surface IS2a toward the second outer peripheral surface OS2a in a front-to-rear view. However, as shown in FIG. 4, the third chamfered portion R3a does not reach the fourth front surface SF4a. The provision of the third chamfered portion R3a reduces the thickness of the rear end of the second connecting portion PC2a. The third chamfered portion R3a contacts the frame portion 11b. Therefore, the third chamfered portion R3a contacts the resin main body member 11.

[0034] The fourth front surface SF4a is connected to the second inner peripheral surface IS2a via a fourth chamfered portion R4a. More specifically, the fourth chamfered portion R4a is recessed to the right in a front-to-rear view. The fourth chamfered portion R4a is also recessed to the rear in a left-right view. Therefore, as shown in FIG. 5, the fourth chamfered portion R4a is recessed from the second inner peripheral surface IS2a toward the second outer peripheral surface OS2a in a front-to-rear view. However, as shown in FIG. 4, the fourth chamfered portion R4a does not reach the fourth rear surface SB4a. The fourth chamfered portion R4a reduces the thickness of the front end of the second connecting portion PC2a. The fourth chamfered portion R4a contacts the frame portion 11b. Therefore, the fourth chamfered portion R4a contacts the resin main body member 11.

[0035] The exposed portion PE extends rightward from the lower end of the main body portion MBa. More specifically, the exposed portion PE extends rightward from the lower end of the third portion P3a. As shown in FIG. 5 , the exposed portion PE is exposed from the resin main body member 11.

[0036] The first ground terminals 16b1 to 16b3 and 16f1 to 16f3 are connected to a ground potential. The first ground terminals 16b1 to 16b3 and 16f1 to 16f3 are supported by the resin main body member 11. More specifically, a portion of the first ground terminal 16b1 and a portion of the first ground terminal 16f1 are embedded in the left side of the frame portion 11b. As a result, the first ground terminals 16b1 and 16f1 are aligned in a row from back to front. A portion of the first ground terminal 16b2 is embedded in the rear side of the frame portion 11b. A portion of the first ground terminal 16b3 and a portion of the first ground terminal 16f3 are embedded in the right side of the frame portion 11b. As a result, the first ground terminals 16b3 and 16f3 are aligned in a row from back to front. A portion of the first ground terminal 16f2 is embedded in the front side of the frame portion 11b. The first ground terminals 16b1 to 16b3 and 16f1 to 16f3 are made by bending a plate-shaped metal member, and are made of a copper-based material such as phosphor bronze.

[0037] The structures of the first ground terminals 16b1-16b3 and 16f1-16f3 will be described in detail with reference to the drawings. Because the first ground terminals 16b1-16b3 and 16f1-16f3 have the same shape, a description of the structures of the first ground terminals 16b1-16b3 and 16f1 and 16f2 will be omitted. FIG. 6 is a perspective view of the first ground terminal 16f3 according to the first embodiment. FIG. 7 is a cross-sectional view of the first ground terminal 16f3 and frame 11b according to the first embodiment.

[0038] 6 and 7, the first ground terminal 16f3 includes a main body portion MBb and a support portion PS. The main body portion MBb has a first portion P1b, a second portion P2b, a third portion P3b, a first connecting portion PC1b, and a second connecting portion PC2b.

[0039] The first portion P1b has a first left surface SL1b facing leftward, a first right surface SR1b facing rightward, a first rear surface SB1b and a first front surface SF1b aligned in the front-to-rear direction, and a first bottom surface SD1b facing downward. The first left surface SL1b is not in contact with the resin body member 11. Therefore, the first left surface SL1b is exposed from the resin body member 11. The first right surface SR1b, the first rear surface SB1b, the first front surface SF1b, and the first bottom surface SD1b are in contact with the frame portion 11b. Therefore, the first right surface SR1b, the first rear surface SB1b, the first front surface SF1b, and the first bottom surface SD1b are in contact with the resin body member 11. The first portion P1b extends in the up-down direction. In this embodiment, the length of the first portion P1b in the left-to-right direction is uniform.

[0040] The second portion P2b is located above the first portion P1b. The second portion P2b has a second rear surface SB2b and a second front surface SF2b aligned in the front-rear direction, a first upper surface SU1b facing upward, and a second lower surface SD2b facing downward. The first upper surface SU1b is not in contact with the resin body member 11. Therefore, the first upper surface SU1b is exposed from the resin body member 11. The second rear surface SB2b, the second front surface SF2b, and the second lower surface SD2b are in contact with the frame portion 11b. Therefore, the second rear surface SB2b, the second front surface SF2b, and the second lower surface SD2b are in contact with the resin body member 11. The second portion P2b extends in the left-right direction. In this embodiment, the length of the second portion P2b in the up-down direction is uniform.

[0041] The third portion P3b is located below the second portion P2b. The third portion P3b has a second left surface SL2b facing leftward, a second right surface SR2b facing rightward, and a third rear surface SB3b and a third front surface SF3b aligned in the front-to-rear direction. The second right surface SR2b does not contact the resin body member 11. Therefore, the second right surface SR2b is exposed from the resin body member 11. The second left surface SL2b, the third rear surface SB3b, the third front surface SF3b, and the second lower surface SD2b are in contact with the frame portion 11b. Therefore, the second left surface SL2b, the third rear surface SB3b, the third front surface SF3b, and the second lower surface SD2b are in contact with the resin body member 11. The third portion P3b extends in the up-down direction. In this embodiment, the length of the third portion P3b in the left-to-right direction is uniform.

[0042] The first connecting portion PC1b physically connects the upper end of the first portion P1b and the left end of the second portion P2b and is curved. The first connecting portion PC1b has a first inner circumferential surface IS1b facing downward and to the right, a first outer circumferential surface OS1b facing upward and to the left, and a third rear surface SB3b and a third front surface SF3b aligned in the front-to-rear direction. The first inner circumferential surface IS1b is connected to the first right surface SR1b and the second lower surface SD2b. The first outer circumferential surface OS1b is connected to the first left surface SL1b and the first upper surface SU1b. The third rear surface SB3b is connected to the first rear surface SB1b and the second rear surface SB2b. The third front surface SF3b is connected to the first front surface SF1b and the second front surface SF2b. The first outer circumferential surface OS1b does not contact the resin body member 11. Therefore, the first outer peripheral surface OS1b is exposed from the resin body member 11. The first inner peripheral surface IS1b, the third rear surface SB3b, and the third front surface SF3b are in contact with the frame portion 11b. Therefore, the first inner peripheral surface IS1b, the third rear surface SB3b, and the third front surface SF3b are in contact with the resin body member 11.

[0043] The second connecting portion PC2b physically connects the right end of the second portion P2b and the upper end of the third portion P3b and is curved. The second connecting portion PC2b has a second inner peripheral surface IS2b facing downward and left, a second outer peripheral surface OS2b facing upward and right, and a fourth rear surface SB4b and a fourth front surface SF4b aligned in the front-to-rear direction. The second inner peripheral surface IS2b is connected to the second lower surface SD2b and the second left surface SL2b. The second outer peripheral surface OS2b is connected to the first upper surface SU1b and the second right surface SR2b. The fourth rear surface SB4b is connected to the second rear surface SB2b and the third rear surface SB3b. The fourth front surface SF4b is connected to the second front surface SF2b and the third front surface SF3b. ​​The second outer peripheral surface OS2b does not contact the resin body member 11. Therefore, the second outer peripheral surface OS2b is exposed from the resin body member 11. The second inner peripheral surface IS2b, the fourth rear surface SB4b, and the fourth front surface SF4b are in contact with the frame portion 11b. Therefore, the second inner peripheral surface IS2b, the fourth rear surface SB4b, and the fourth front surface SF4b are in contact with the resin body member 11.

[0044] In this embodiment, as shown in Fig. 4, the first connecting portion PC1b is provided with a first chamfered portion R1b and a second chamfered portion R2b. The second connecting portion PC2b is provided with a third chamfered portion R3b and a fourth chamfered portion R4b. The second chamfered portion R2b has a front-to-back symmetrical structure with the first chamfered portion R1b. The fourth chamfered portion R4b has a front-to-back symmetrical structure with the third chamfered portion R3b. In this embodiment, the first chamfered portion R1b, the second chamfered portion R2b, the third chamfered portion R3b, and the fourth chamfered portion R4b are not connected to one another.

[0045] The third rear surface SB3b is connected to the first inner peripheral surface IS1b via the first chamfered portion R1b. More specifically, the first chamfered portion R1b is recessed toward the left in a front-to-rear view. The first chamfered portion R1b is also recessed toward the front in a left-right view. Therefore, as shown in FIG. 7, the first chamfered portion R1b is recessed from the first inner peripheral surface IS1b toward the first outer peripheral surface OS1b in a front-to-rear view. However, as shown in FIG. 6, the first chamfered portion R1b does not reach the third front surface SF3b. ​​The provision of the first chamfered portion R1b reduces the thickness of the rear end of the first connecting portion PC1b. The first chamfered portion R1b contacts the frame portion 11b. Therefore, the first chamfered portion R1b contacts the resin main body member 11.

[0046] The third front surface SF3b is connected to the first inner circumferential surface IS1b via the second chamfered portion R2b. More specifically, the second chamfered portion R2b is recessed toward the left in a front-to-rear view. The second chamfered portion R2b is also recessed toward the rear in a left-right view. Therefore, as shown in FIG. 7, the second chamfered portion R2b is recessed from the first inner circumferential surface IS1b toward the first outer circumferential surface OS1b in a front-to-rear view. However, as shown in FIG. 6, the second chamfered portion R2b does not reach the third rear surface SB3b. The provision of the second chamfered portion R2b reduces the thickness of the front end of the first connecting portion PC1b. The second chamfered portion R2b contacts the frame portion 11b. Therefore, the second chamfered portion R2b contacts the resin main body member 11.

[0047] The fourth rear surface SB4b is connected to the second inner peripheral surface IS2b via a third chamfered portion R3b. More specifically, the third chamfered portion R3b is recessed to the right in a front-to-rear view. Furthermore, the third chamfered portion R3b is recessed to the front in a left-right view. Therefore, as shown in FIG. 7, the third chamfered portion R3b is recessed from the second inner peripheral surface IS2b toward the second outer peripheral surface OS2b in a front-to-rear view. However, as shown in FIG. 6, the third chamfered portion R3b does not reach the fourth front surface SF4b. The provision of the third chamfered portion R3b reduces the thickness of the rear end of the second connecting portion PC2b. The third chamfered portion R3b contacts the frame portion 11b. Therefore, the third chamfered portion R3b contacts the resin main body member 11.

[0048] The fourth front surface SF4b is connected to the second inner peripheral surface IS2b via a fourth chamfered portion R4b. More specifically, the fourth chamfered portion R4b is recessed to the right in a front-to-rear view. The fourth chamfered portion R4b is also recessed to the rear in a left-right view. Therefore, as shown in FIG. 7, the fourth chamfered portion R4b is recessed from the second inner peripheral surface IS2b toward the second outer peripheral surface OS2b in a front-to-rear view. However, as shown in FIG. 6, the fourth chamfered portion R4b does not reach the fourth rear surface SB4b. The provision of the fourth chamfered portion R4b reduces the thickness of the front end of the second connecting portion PC2b. The fourth chamfered portion R4b contacts the frame portion 11b. Therefore, the fourth chamfered portion R4b contacts the resin main body member 11.

[0049] The support portion PS extends rightward from the lower end of the first portion P1b.

[0050] In the first connector 10 described above, the first connector 10 is mounted on a first circuit board (not shown) so that the underside of the resin body member 11 faces the first circuit board. More specifically, portions of the first signal terminals 15l and 15r and portions of the first ground terminals 16b1, 16b2, 16b3, 16f1, 16f2, and 16f3 are exposed from the underside of the resin body member 11. Solder is then applied to each of these portions. As a result, the portions of the first signal terminals 15l and 15r and the first ground terminals 16b1 to 16b3 and 16f1 to 16f3 are electrically connected to electrodes of the first circuit board.

[0051] In the first connector 10, the exposed portion PE extends rightward from the lower end of the first portion P1a. As a result, the exposed portion PE is located opposite the second portion P2a when viewed from the first portion P1a. The exposed portion PE is the portion to which solder is applied when the first connector 10 is mounted. Meanwhile, the first portion P1a is the portion that is held by the resin body member 11. In this way, by separating the first portion P1a and the exposed portion PE, the first portion P1a is easily fixed to the resin body member 11, and the exposed portion PE is easily fixed to the first circuit board.

[0052] [Structure of Second Connector] Next, the structure of the second connector 110 will be described with reference to the drawings. Fig. 8 is a perspective view of the second connector 110 according to the first embodiment. Fig. 9 is a perspective view of the second signal terminals 115l, 115r and the second ground terminals 116b, 116f of the second connector 110 according to the first embodiment.

[0053] 8 and 9, the second connector 110 includes a resin body member 111, contact terminals 114fl, 114fr, 114bl, and 114br, second signal terminals 115l and 115r, and second ground terminals 116b and 116f. The resin body member 111, the contact terminals 114fl, 114fr, 114bl, and 114br, the second signal terminals 115l and 115r, and the second ground terminals 116b and 116f are integrally molded by insert molding. The second signal terminals 115l and 115r and the second ground terminals 116b and 116f correspond to "second external connection terminals."

[0054] As shown in Fig. 8, the resin body member 111 includes a protrusion 111a, a frame portion 111b, and a connecting portion 111c. The protrusion 111a extends along the front-rear axis when viewed from above. More specifically, the protrusion 111a has a rectangular parallelepiped shape. When viewed from above, the protrusion 111a has two long sides extending along the front-rear axis and two short sides extending along the left-right axis.

[0055] When viewed from above, the frame 111b has a ring shape that surrounds the periphery of the protrusion 111a. The frame 111b has left and right sides that extend along the front-rear axis and front and rear sides that extend along the left-right axis. When viewed from below, the protrusion 111a is located within the area surrounded by the frame 111b. The protrusion 111a does not contact the frame 111b.

[0056] The connecting portion 111c is located between the protruding portion 111a and the frame portion 111b when viewed from above, and connects the protruding portion 111a to the frame portion 111b. The connecting portion 111c connects the upper portion of the protruding portion 111a to the upper portion of the frame portion 111b. The material of the resin main body member 111 is an insulating material. The material of the resin main body member 111 is, for example, resin.

[0057] The contact terminals 114fl, 114fr, 114bl, and 114br are connected to a ground potential. The contact terminals 114fl, 114fr, 114bl, and 114br are supported by the resin body member 111. More specifically, the contact terminal 114fl is supported on the left side of the frame portion 111b. The contact terminal 114fr is supported on the right side of the frame portion 111b. The contact terminal 114bl is supported on the left side of the frame portion 111b. The contact terminal 114br is supported on the right side of the frame portion 111b. The material of the contact terminals 114fl, 114fr, 114bl, and 114br is, for example, a copper-based material such as phosphor bronze.

[0058] High-frequency signals are input to and output from the second signal terminals 115l and 115r. The second signal terminals 115l and 115r are supported by the resin main body member 111. More specifically, a portion of the second signal terminal 115l is embedded in the left side of the frame portion 111b. The second signal terminals 115l are aligned in a row along the front-rear axis. A portion of the second signal terminal 115r is embedded in the right side of the frame portion 111b. The second signal terminals 115r are aligned in a row along the front-rear axis. The second signal terminals 115l and 115r are fabricated by bending a rod-shaped metal member. The second signal terminals 115l and 115r are made of a copper-based material such as phosphor bronze.

[0059] The second ground terminals 116b, 116f are connected to a ground potential. The second ground terminals 116b, 116f are supported by the resin body member 111. More specifically, a portion of the second ground terminal 116b is embedded in the rear end of the frame portion 111b. A portion of the second ground terminal 116b is embedded in the front end of the frame portion 111b. The second ground terminals 116b, 116f are fabricated by bending a rod-shaped metal member. The second ground terminals 116b, 116f are made of a copper-based material such as phosphor bronze.

[0060] In the second connector 110 described above, the second connector 110 is mounted on a second circuit board (not shown) so that the top surface of the resin body member 111 faces the second circuit board. More specifically, portions of the contact terminals 114fl, 114fr, 114bl, and 114br, portions of the second signal terminals 115l and 115r, and portions of the second ground terminals 116b and 116f are exposed from the top surface of the resin body member 11. Solder is then applied to each of these portions. As a result, the contact terminals 114fl, 114fr, 114bl, and 114br, the second signal terminals 115l and 115r, and the second ground terminals 116b and 116f are electrically connected to electrodes of the second circuit board.

[0061] The frame portion 11b of the first connector 10 is inserted into the area surrounded by the frame portion 111b of the second connector 110. At this time, the protrusion portion 111a of the second connector 110 is inserted into the area surrounded by the frame portion 11b of the first connector 10. As a result, when the first connector 10 and the second connector 110 are coupled, the first ground terminals 16b1 to 16b3 come into contact with the second ground terminal 116b and the contact terminals 114bl and 114br. When the first connector 10 and the second connector 110 are coupled, the first ground terminals 16f1 to 16f3 come into contact with the second ground terminal 116f and the contact terminals 114fl and 114fr. When the first connector 10 and the second connector 110 are coupled, each of the first signal terminals 15l comes into contact with each of the second signal terminals 115l. When the first connector 10 and the second connector 110 are mated, each of the first signal terminals 15r comes into contact with each of the second signal terminals 115r.

[0062] [Effect] The first connector 10 can suppress stress concentration on a portion of the terminal when mated with a mating connector. The first signal terminal 15r will be used as an example. As a comparative example, a first signal terminal 25r that does not have the first chamfered portion R1a, the second chamfered portion R2a, the third chamfered portion R3a, and the fourth chamfered portion R4a will be described with reference to the drawings. FIG. 10 is a cross-sectional view showing damage to the resin body member 11 due to contact between the first signal terminal 25r and the second signal terminal 115r. The resin body member 11 is present between adjacent first signal terminals 25r. When the first connector 10 and the second connector 110 are mated, the first signal terminal 25r comes into contact with the second signal terminal 115r. As a result, the first signal terminal 25r receives a force in the right direction from the second signal terminal 115r. As a result, stress is concentrated at the intersection line between the third rear surface SB3a and the first inner circumferential surface IS1a, the intersection line between the third front surface SF3a and the first inner circumferential surface IS1a, the intersection line between the fourth rear surface SB4a and the first inner circumferential surface IS1a, and the intersection line between the fourth front surface SF4a and the first inner circumferential surface IS1a. In this case, there is a possibility that the resin body member 11 may be damaged. As a result, as shown in FIG. 10 , the portion of the resin body member 11 surrounded by the first signal terminal 25r may tilt to the right together with the first signal terminal 15r.

[0063] Therefore, in the first connector 10, the third rear surface SB3a is connected to the first inner circumferential surface IS1a via the first chamfered portion R1a. This shifts the stress concentration point from the intersection (line) between the third rear surface SB3a and the first inner circumferential surface IS1a to the first chamfered portion R1a (surface), thereby dispersing the stress. The third front surface SF3a is connected to the first inner circumferential surface IS1a via the second chamfered portion R2a. This shifts the stress concentration point from the intersection (line) between the third front surface SF3a and the first inner circumferential surface IS1a to the second chamfered portion R2a (surface), thereby dispersing the stress. The fourth rear surface SB4a is connected to the second inner circumferential surface IS2a via the third chamfered portion R3a. As a result, the stress concentration point moves from the intersection line (line) between the fourth rear surface SB4a and the first inner circumferential surface IS1a to the third chamfered portion R3a (surface), thereby dispersing the stress. The fourth front surface SF4a is connected to the second inner circumferential surface IS2a via the fourth chamfered portion R4a. As a result, the stress concentration point moves from the intersection line (line) between the fourth front surface SF4a and the first inner circumferential surface IS1a to the fourth chamfered portion R4a (surface), thereby dispersing the stress. Therefore, with the first connector 10, stress concentration on one part of the terminal can be suppressed when mated with a mating connector.

[0064] Furthermore, the first connector 10 allows the first signal terminal 15r to be miniaturized in the left-right direction. More specifically, the first chamfered portion R1a and the second chamfered portion R2a are each recessed from the first inner circumferential surface IS1a toward the first outer circumferential surface OS1a when viewed in the front-rear direction. The third chamfered portion R3a and the fourth chamfered portion R4a are each recessed from the second inner circumferential surface IS2a toward the second outer circumferential surface OS2a when viewed in the front-rear direction. The first chamfered portion R1a, the second chamfered portion R2a, the third chamfered portion R3a, and the fourth chamfered portion R4a are each in contact with the resin body member 11. This allows the contact area between the first signal terminal 15r and the resin body member 11 to be increased in the region overlapping the first signal terminal 15r when viewed in the up-down direction. Therefore, the first signal terminal 15r can have increased strength against shear stress acting at the contact point between the first signal terminal 15r and the resin body member 11. Therefore, even if the first signal terminal 15r is made smaller in size in the left-right direction, it is possible to ensure strength against shear stress acting at the contact point between the first signal terminal 15r and the resin body member 11. As a result, the first connector 10 allows the first signal terminal to be made smaller in size in the left-right direction.

[0065] Furthermore, the first connector 10 allows for a narrow pitch between the first signal terminals. More specifically, the provision of the first chamfered portion R1a, the second chamfered portion R2a, the third chamfered portion R3a, and the fourth chamfered portion R4a increases the average distance between adjacent first signal terminals 15r in the front-to-rear direction, thereby reducing the capacitance generated between adjacent first signal terminals 15r. This increases the resonant frequency between adjacent first signal terminals 15r. Therefore, even if the pitch between the first signal terminals is narrowed, the impact on the high-frequency characteristics of high-frequency signals input and output to the first signal terminals 15r can be suppressed. As a result, the first connector 10 allows for a narrow pitch between the first signal terminals.

[0066] [First Modification] A first signal terminal 15r according to a first modification of the present invention will be described below with reference to the drawings. Fig. 11 is a perspective view of the first signal terminal 15r according to the first modification. Note that, with regard to the first signal terminal 15r according to the first modification, only the differences from the first signal terminal 15r according to the first embodiment will be described, and the rest will be omitted.

[0067] As shown in FIG. 11, the first signal terminal 15r according to the first modification differs from the first signal terminal 15r according to the first embodiment in that the first chamfered portion R1a is connected to the third chamfered portion R3a, and the second chamfered portion R2a is connected to the fourth chamfered portion R4a.

[0068] More specifically, the first chamfered portion R1a and the third chamfered portion R3a are connected to form the chamfered portion Ra. The chamfered portion Ra includes the first chamfered portion R1a and the third chamfered portion R3a. The second chamfered portion R2a and the fourth chamfered portion R4a are connected to form the chamfered portion Rb. The chamfered portion Rb includes the second chamfered portion R2a and the fourth chamfered portion R4a.

[0069] The second rear surface SB2a is connected to the second lower surface SD2a via a chamfered portion Ra, and the second front surface SF2a is connected to the second lower surface SD2a via a chamfered portion Rb.

[0070] The first connector 10a including the first signal terminal 15r according to the first modified example as described above also achieves the same effects as the first connector 10.

[0071] [Second Modification] A first signal terminal 15r according to a second modification of the present invention will be described below with reference to the drawings. Fig. 12 is a cross-sectional view of the first chamfered portion R1a, the second chamfered portion R2a, the third chamfered portion R3a, and the fourth chamfered portion R4a according to the second modification, viewed from the left. Regarding the first signal terminal 15r according to the second modification, only the differences from the first signal terminal 15r according to the first embodiment will be described, and the rest will be omitted.

[0072] As shown in FIG. 12, the first signal terminal 15r according to the second modified example differs from the first signal terminal 15r according to the first embodiment in that the lengths of the first chamfered portion R1a and the third chamfered portion R3a in the left-right direction are increased toward the rear, and the lengths of the second chamfered portion R2a and the fourth chamfered portion R4a in the left-right direction are increased toward the front.

[0073] The first connector 10b including the first signal terminal 15r according to the second modified example as described above also achieves the same effects as the first connector 10. Furthermore, the first connector 10b can prevent the first signal terminal from coming off the resin body member. The length of the first chamfered portion R1a in the left-right direction increases toward the rear. This allows the first coupling portion PC1 to hook onto the resin body member 11 when the first signal terminal 15r is subjected to a rearward force. The length of the second chamfered portion R2a in the left-right direction increases toward the front. This allows the first coupling portion PC1 to hook onto the resin body member 11 when the first signal terminal 15r is subjected to a forward force. The length of the third chamfered portion R3a in the left-right direction increases toward the rear. This allows the second coupling portion PC2 to hook onto the resin body member 11 when the first signal terminal 15r is subjected to a rearward force. Furthermore, the length of the fourth chamfered portion R4a in the left-right direction increases toward the front. This allows the second connecting portion PC2 to catch on the resin body member 11 when the first signal terminal 15r receives a force in the forward direction. Therefore, the first connector 10b can prevent the first signal terminal from coming off the resin body member.

[0074] [Third Modification] A first signal terminal 15r according to a third modification of the present invention will be described below with reference to the drawings. Fig. 13 is a cross-sectional view of the right end of the first connecting portion PC1a and the frame portion 11b according to the third modification, viewed leftward. Fig. 14 is a cross-sectional view of the left end of the second connecting portion PC2a and the frame portion 11b according to the third modification, viewed leftward. Note that with regard to the first signal terminal 15r according to the third modification, only the differences from the first signal terminal 15r according to the first embodiment will be described, and the rest will be omitted.

[0075] The first signal terminal 15r according to the third modification differs from the first signal terminal 15r according to the first embodiment in that the length of the first inner circumferential surface IS1a in the front-rear direction is shorter than the length of the first outer circumferential surface OS1a and the length of the second inner circumferential surface IS2a in the front-rear direction is shorter than the length of the second outer circumferential surface OS2a. As a result, as shown in FIG. 13 , at the right end of the first connecting portion PC1a, the length of the first inner circumferential surface IS1a in the front-rear direction is shorter than the length of the first outer circumferential surface OS1a. Furthermore, as shown in FIG. 14 , at the left end of the second connecting portion PC2a, the length of the second inner circumferential surface IS2a in the front-rear direction is shorter than the length of the second outer circumferential surface OS2a.

[0076] The first connector 10c including the first signal terminal 15r according to the third modified example as described above also achieves the same effects as the first connector 10. Furthermore, the first connector 10c can further suppress stress concentration on one portion of the terminal when mated with a mating connector.

[0077] [Fourth Modification] A first signal terminal 15r according to a fourth modification of the present invention will be described below with reference to the drawings. Fig. 15 is a cross-sectional view of the right end of the first connecting portion PC1a and the frame portion 11b according to the fourth modification, viewed from the left. Fig. 16 is a cross-sectional view of the left end of the second connecting portion PC2a and the frame portion 11b according to the fourth modification, viewed from the left. Note that with regard to the first signal terminal 15r according to the fourth modification, only the differences from the first signal terminal 15r according to the first embodiment will be described, and the rest will be omitted.

[0078] The first signal terminal 15r according to the fourth modification differs from the first signal terminal 15r according to the first embodiment in that the length of the first inner circumferential surface IS1a in the front-rear direction is shorter than the length of the first outer circumferential surface OS1a, and the length of the second inner circumferential surface IS2a in the front-rear direction is shorter than the length of the second outer circumferential surface OS2a. More specifically, as shown in FIGS. 15 and 16 , the right end of the first inner circumferential surface IS1a has a downwardly protruding arc shape when viewed in the left-right direction. The right end of the second inner circumferential surface IS2a also has a downwardly protruding arc shape when viewed in the left-right direction.

[0079] The first connector 10d including the first signal terminal 15r according to the fourth modified example as described above also achieves the same effects as the first connector 10. Furthermore, the first connector 10d can further suppress the concentration of stress on one portion of the terminal when mated with a mating connector.
