DETAILED DESCRIPTION OF THE INVENTION

[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 15a to 15d are arranged in this order 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. In addition, 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 forward direction and the rearward 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 cases where at least a portion of the first member is positioned directly above the second member, and cases 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 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] 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 connected, the second connector 110 is located above the first connector 10.

[0018] [Structure of the 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 ground terminals 12a-12d, the second ground terminals 13a-13d, the contact terminal 14, the first signal terminals 15a-15d, and the second signal terminals 16a-16d of the first connector 10 according to the first embodiment.

[0019] As shown in Figures 2 and 3, the first connector 10 includes a resin body member 11, first ground terminals 12a to 12d, second ground terminals 13a to 13d, a contact terminal 14, first signal terminals 15a to 15d, and second signal terminals 16a to 16d.

[0020] As shown in Fig. 2, the resin body member 11 includes a protrusion 11a, a frame portion 11b, and a connecting portion 11c. The protrusion 11a extends along the front-rear axis when viewed downward. More specifically, the protrusion 11a has a rectangular parallelepiped shape. When viewed downward, the protrusion 11a has two long sides extending along the front-rear axis and two short sides extending along the left-right axis.

[0021] When viewed from below, the frame 11b has a ring shape that surrounds the periphery of the protrusion 11a. The frame 11b has left and right sides extending along the front-rear axis and front and rear sides extending along the left-right axis. When viewed from below, the protrusion 11a is located within the area surrounded by the frame 11b. The protrusion 11a does not contact the frame 11b.

[0022] When viewed from below, the connecting portion 11c is located between the protrusion 11a and the frame portion 11b, and connects the protrusion 11a and the frame portion 11b. The connecting portion 11c connects the lower portion of the protrusion 11a and the lower portion of the frame portion 11b. The material of the resin main body member 11 is an insulating material. The material of the resin main body member 11 is, for example, resin.

[0023] The first ground terminals 12a-12d and the second ground terminals 13a-13d are connected to a ground potential. The first ground terminals 12a-12d and the second ground terminals 13a-13d are supported by the resin main body member 11. More specifically, portions of the first ground terminals 12a-12d are embedded in the left side of the frame portion 11b. As a result, the first ground terminals 12a-12d are supported by the frame portion 11b so as to be aligned along the front-to-rear axis in the left region of the protrusion portion 11a. The first ground terminals 12a-12d are aligned in a line from rear to front. The first ground terminals 12a-12d are fabricated by bending a rod-shaped metal member. The first ground terminals 12a-12d are made of a copper-based material such as phosphor bronze.

[0024] The second ground terminals 13a to 13d are partially embedded in the right side of the frame 11b. The second ground terminals 13a to 13d are supported by the frame 11b so as to be aligned along the front-to-rear axis in the region to the right of the protrusion 11a. The second ground terminals 13a to 13d are located to the right of the first ground terminals 12a to 12d. The second ground terminals 13a to 13d are aligned in a row from rear to front. The second ground terminals 13a to 13d are fabricated by bending a rod-shaped metal member. The second ground terminals 13a to 13d are made of a copper-based material such as phosphor bronze.

[0025] The contact terminal 14 is connected to a ground potential. The contact terminal 14 is supported by the resin body member 11. More specifically, the contact terminal 14 is supported by the front, rear, left, and right sides of the frame portion 11b. Therefore, when viewed from below, the contact terminal 14 has a ring shape that surrounds the periphery of the protrusion portion 11a. The contact terminal 14 has left and right sides extending along the front-rear axis and front and rear sides extending along the left-right axis. The contact terminal 14 is produced by bending a metal member. The material of the contact terminal 14 is, for example, a copper-based material such as phosphor bronze.

[0026] High-frequency signals are input to and output from the first signal terminals 15a-15d and the second signal terminals 16a-16d. The first signal terminals 15a-15d and the second signal terminals 16a-16d are supported by the resin main body member 11. More specifically, portions of the first signal terminals 15a-15d are embedded in the left portion of the protrusion 11a. As a result, the first signal terminals 15a-15d are supported by the protrusion 11a so as to be aligned along the front-to-rear axis in the left region of the protrusion 11a. The first signal terminals 15a-15d are aligned in a line from rear to front. The first signal terminal 15a, the first ground terminal 12a, the first signal terminal 15b, the first ground terminal 12b, the first signal terminal 15c, the first ground terminal 12c, the first signal terminal 15d, and the first ground terminal 12d are aligned in this order from rear to front. In other words, the first signal terminals 15a-15d and the first ground terminals 12a-12d are aligned on a straight line parallel to the front-to-rear direction when viewed to the right. Also, when viewed to the right, one of the first ground terminals 12a-12d is located between two adjacent first signal terminals. When viewed to the right, one of the first signal terminals 15a-15d is located between two adjacent first ground terminals. The first signal terminals 15a-15d are fabricated by bending a rod-shaped metal member. The first signal terminals 15a-15d are made of a copper-based material such as phosphor bronze.

[0027] Portions of the second signal terminals 16a-16d are embedded in the right portion of the protrusion 11a. As a result, the second signal terminals 16a-16d are supported by the protrusion 11a so as to be aligned along the front-to-rear axis in the right region of the protrusion 11a. Therefore, the second signal terminals 16a-16d are located to the right of the first signal terminals 15a-15d. The second signal terminals 16a-16d are aligned in a line from rear to front. The second ground terminal 13a, the second signal terminal 16a, the second ground terminal 13b, the second signal terminal 16b, the second ground terminal 13c, the second signal terminal 16c, the second ground terminal 13d, and the second signal terminal 16d are aligned in this order from rear to front. In other words, the second signal terminals 16a-16d and the second ground terminals 13a-13d are aligned on a straight line parallel to the front-to-rear direction when viewed from the left. Additionally, when viewed from the left, one of the second ground terminals 13a to 13d is located between two adjacent second signal terminals. When viewed from the left, one of the second signal terminals 16a to 16d is located between two adjacent second ground terminals. The second signal terminals 16a to 16d are made by bending a rod-shaped metal member. The second signal terminals 16a to 16d are made of a copper-based material such as phosphor bronze.

[0028] The first signal terminal 15a, the second signal terminal 16a, the first signal terminal 15b, the second signal terminal 16b, the first signal terminal 15c, the second signal terminal 16c, the first signal terminal 15d, and the second signal terminal 16d are arranged in this order from rear to front. In other words, the first signal terminals 15a-15d and the second signal terminals 16a-16d are arranged on a straight line parallel to the front-to-rear direction when viewed from the right or left. Furthermore, when viewed from the right, one of the second signal terminals 16a-16d is located between two adjacent first signal terminals. Furthermore, when viewed from the left, one of the first signal terminals 15a-15d is located between two adjacent second signal terminals.

[0029] The structures of the first signal terminals 15a to 15d and the second signal terminals 16a to 16d will be described in detail with reference to the drawings, taking the first signal terminal 15a and the second signal terminal 16a as an example. In this embodiment, since the first signal terminals 15a to 15d have the same shape as each other, description of the structure of the first signal terminals 15b to 15d will be omitted. In addition, in this embodiment, since the second signal terminals 16a to 16d have the same shape as each other, description of the structure of the second signal terminals 16b to 16d will be omitted. FIG. 4 is a perspective view of the first signal terminal 15a according to the first embodiment. FIG. 5 is a cross-sectional view of the first signal terminal 15a and the protrusion 11a according to the first embodiment. FIG. 6 is a perspective view of the second signal terminal 16a according to the first embodiment. FIG. 7 is a cross-sectional view of the second signal terminal 16a and the protrusion 11a according to the first embodiment.

[0030] As shown in FIGS. 4 and 5, the first signal terminal 15a includes a first portion P1, a second portion P2, a third portion P3, and a first exposed portion PE1. The first portion P1 extends in the vertical direction. The second portion P2 extends to the right from the upper end of the first portion P1. The third portion P3 extends downward from the right end of the second portion P2. The first exposed portion PE1 extends to the left from the lower end of the first portion P1. The vertical length of the third portion P3 is shorter than the vertical length of the first portion P1. Furthermore, as shown in FIG. 4, the front-to-rear length of the lower portion of the third portion P3 is longer than the front-to-rear length of the upper portion of the third portion P3. As a result, the front-to-rear length of the third portion P3 is longer than the front-to-rear length of the second portion P2.

[0031] As shown in FIGS. 4 and 5, the first signal terminal 15a has a first main surface MS1 and a second main surface MS2 that are parallel to each other, and a first side surface SS1 and a second side surface SS2 that connect the first main surface MS1 and the second main surface MS2. The first main surface MS1 includes the upper main surface of the first exposed portion PE1, the left main surface of the first portion P1, the upper main surface of the second portion P2, and the right main surface of the third portion P3. The second main surface MS2 includes the lower main surface of the first exposed portion PE1, the lower main surface of the first portion P1, the right main surface of the first portion P1, the lower main surface of the second portion P2, and the left main surface of the third portion P3. As shown in FIG. 4, the first side surface SS1 is the rear side surface of the first signal terminal 15a. The second side surface SS2 is the front side surface of the first signal terminal 15a.

[0032] As shown in FIGS. 6 and 7, the second signal terminal 16a includes a fourth portion P4, a fifth portion P5, a sixth portion P6, and a second exposed portion PE2. The fourth portion P4 extends in the vertical direction. The fifth portion P5 extends leftward from the upper end of the fourth portion P4. The sixth portion P6 extends downward from the left end of the fifth portion P5. The second exposed portion PE2 extends rightward from the lower end of the fourth portion P4. The vertical length of the sixth portion P6 is shorter than the vertical length of the fourth portion P4. Furthermore, as shown in FIG. 6, the front-to-rear length of the lower portion of the sixth portion P6 is longer than the front-to-rear length of the upper portion of the sixth portion P6. As a result, the front-to-rear length of the sixth portion P6 is longer than the front-to-rear length of the fifth portion P5.

[0033] As shown in FIGS. 6 and 7, the second signal terminal 16a has a third main surface MS3 and a fourth main surface MS4 that are parallel to each other, and a third side surface SS3 and a fourth side surface SS4 that connect the third main surface MS3 and the fourth main surface MS4. The third main surface MS3 includes the upper main surface of the second exposed portion PE2, the right main surface of the fourth portion P4, the upper main surface of the fifth portion P5, and the left main surface of the sixth portion P6. The fourth main surface MS4 includes the lower main surface of the second exposed portion PE2, the lower main surface of the fourth portion P4, the left main surface of the fourth portion P4, the lower main surface of the fifth portion P5, and the right main surface of the sixth portion P6. As shown in FIG. 6, the third side surface SS3 is the rear side surface of the second signal terminal 16a. The fourth side surface SS4 is the front side surface of the second signal terminal 16a.

[0034] In this embodiment, as shown in FIGS. 4 and 6, the vertical length of the fourth portion P4 is longer than the vertical length of the first portion P1. As a result, the upper end of the right main surface of the third portion P3 is located lower than the lower end of the left main surface of the sixth portion P6. Furthermore, the vertical center of the right main surface of the third portion P3 is located at a different position from the vertical center of the left main surface of the sixth portion P6. More specifically, in this embodiment, the vertical center of the right main surface of the third portion P3 is located lower than the vertical center of the left main surface of the sixth portion P6.

[0035] Any one of the first signal terminals 15a to 15d is defined as the third signal terminal 150. Any one of the second signal terminals 16a to 16d that is closest to the third signal terminal 150 when viewed from below is defined as the fourth signal terminal 160. When the first signal terminal 15a is defined as the third signal terminal 150, the second signal terminal 16a becomes the fourth signal terminal 160. When the first signal terminal 15b is defined as the third signal terminal 150, the second signal terminal 16b becomes the fourth signal terminal 160. When the first signal terminal 15c is defined as the third signal terminal 150, the second signal terminal 16c becomes the fourth signal terminal 160. When the first signal terminal 15d is defined as the third signal terminal 150, the second signal terminal 16d becomes the fourth signal terminal 160. As described above, in this embodiment, there are a plurality of third signal terminals 150 and a plurality of fourth signal terminals 160. In this embodiment, as an example, a case will be described in which the first signal terminal 15a is defined as the third signal terminal 150. In this case, the second signal terminal 16a becomes the fourth signal terminal 160.

[0036] The positional relationship between the third signal terminal 150 and the fourth signal terminal 160 will be described in detail with reference to the drawings. Fig. 8 is a view of the protrusion 11a, the third signal terminal 150, and the fourth signal terminal 160 according to the first embodiment, viewed from below. Fig. 9 is a view of the third signal terminal 150 and the fourth signal terminal 160 according to the first embodiment, viewed from the front.

[0037] As shown in FIG. 8 , no conductor exists between the third signal terminal 150 and the fourth signal terminal 160. The third signal terminal 150 has a first proximity portion PS1 that is the shortest distance from the fourth signal terminal 160 in the left-right direction when viewed from below. In this embodiment, the first proximity portion PS1 is the right principal surface of the third portion P3 of the third signal terminal 150. Therefore, the vertical length of the first proximity portion PS1 is shorter than the vertical length of the third signal terminal 150. Furthermore, the fourth signal terminal 160 has a second proximity portion PS2 that is the shortest distance from the third signal terminal 150 in the left-right direction when viewed from below. In this embodiment, the second proximity portion PS2 is the left principal surface of the sixth portion P6 of the fourth signal terminal 160. Therefore, the vertical length of the second proximity portion PS2 is shorter than the vertical length of the fourth signal terminal 160.

[0038] As described above, in this embodiment, the upper end of the third portion P3 is located lower than the lower end of the sixth portion P6. Therefore, in this embodiment, the upper end of the first proximity portion PS1 is located lower than the lower end of the second proximity portion PS2, as shown in FIG.

[0039] As described above, the vertical position of the center of the right principal surface of the third portion P3 is different from the vertical position of the center of the left principal surface of the sixth portion P6. Therefore, the vertical position of the center O1 of the first proximity portion PS1 is different from the vertical position of the center O2 of the second proximity portion PS2. More specifically, in this embodiment, the vertical center O1 of the first proximity portion PS1 is located below the vertical center O2 of the second proximity portion PS2.

[0040] The left main surface of the sixth portion P6 has a portion located higher than the right main surface of the third portion P3. Therefore, the second nearby portion PS2 has a portion located higher than the first nearby portion PS1. Furthermore, the right main surface of the third portion P3 has a portion located lower than the left main surface of the sixth portion P6. Therefore, the first nearby portion PS1 has a portion located lower than the second nearby portion PS2.

[0041] The first connector 10 described above is mounted on a first circuit board (not shown) with the underside of the resin body member 11 facing the first circuit board. More specifically, portions of the first ground terminals 12a-12d, the second ground terminals 13a-13d, the contact terminal 14, the first signal terminals 15a-15d, and the second signal terminals 16a-16d are exposed from the underside of the resin body member 11. Solder is then applied to each of these portions. As a result, the first ground terminals 12a-12d, the second ground terminals 13a-13d, the contact terminal 14, the first signal terminals 15a-15d, and the second signal terminals 16a-16d are electrically connected to electrodes of the first circuit board.

[0042] In the first connector 10, the first exposed portion PE1 extends leftward from the lower end of the first portion P1. As a result, the first exposed portion PE1 is located opposite the third portion P3 when viewed from the first portion P1. The first exposed portion PE1 is a portion to which solder is applied when the first connector 10 is mounted. In the first connector 10, the second exposed portion PE2 extends rightward from the lower end of the fourth portion P4. As a result, the second exposed portion PE2 is located opposite the sixth portion P6 when viewed from the fourth portion P4. The second exposed portion PE2 is a portion to which solder is applied when the first connector 10 is mounted. On the other hand, the first portion P1 and the fourth portion P4 are portions held by the resin body member 11. In this way, by separating the first portion P1 from the first exposed portion PE1 and separating the fourth portion P4 from the second exposed portion PE2, the first portion P1 and the fourth portion P4 are easily fixed to the resin main body member 11, and the first exposed portion PE1 and the second exposed portion PE2 are easily fixed to the first circuit board.

[0043] [Structure of the second connector] Next, the structure of second connector 110 will be described with reference to the drawings. Fig. 10 is a perspective view of second connector 110 according to the first embodiment. Fig. 11 is a perspective view of ground terminals 112a-112h, contact terminals 114f, 114b, and signal terminals 115a-115h of second connector 110 according to the first embodiment.

[0044] As shown in FIGS. 10 and 11, the second connector 110 includes a resin main body member 111, ground terminals 112a to 112h, contact terminals 114f and 114b, and signal terminals 115a to 115h.

[0045] As shown in FIG. 10 , the resin body member 111 includes a bottom surface portion 111a and a frame portion 111b. The frame portion 111b has a ring shape when viewed from above. More specifically, the frame portion 111b has a rectangular outer edge and a rectangular inner edge when viewed from above. When viewed from above, the outer edge and the inner edge of the frame portion 111b 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 above, the bottom surface portion 111a covers the upper surface of the area surrounded by the frame portion 111b. The material of the resin body member 111 is an insulating material. The material of the resin body member 111 is, for example, resin.

[0046] The ground terminals 112a to 112h are connected to a ground potential. The ground terminals 112a to 112h are supported by the resin main body member 111. More specifically, the ground terminals 112a to 112d are partially embedded in the left side of the frame portion 111b. As a result, the ground terminals 112a to 112d are lined up in a row from back to front. Furthermore, the ground terminals 112e to 112h are partially embedded in the right side of the frame portion 111b. As a result, the ground terminals 112e to 112h are lined up in a row from back to front. The ground terminals 112a to 112h are fabricated by bending a rod-shaped metal member. The ground terminals 112a to 112h are made of a copper-based material such as phosphor bronze.

[0047] The contact terminals 114f and 114b are connected to a ground potential. The contact terminal 114f is supported by the resin main body member 111. A portion of the contact terminal 114f is embedded in the front end of the left side of the frame portion 111b and the front end of the right side of the frame portion 111b. The contact terminal 114f is produced by bending a metal member. The material of the contact terminal 114f is, for example, a copper-based material such as phosphor bronze. Note that the structure of the contact terminal 114b is symmetrical to the structure of the contact terminal 114f from front to back, and therefore a description thereof will be omitted.

[0048] High-frequency signals are input to and output from the signal terminals 115a to 115h. The signal terminals 115a to 115h are supported by the resin main body member 111. More specifically, part of the signal terminals 115a to 115d are embedded in the left side of the frame portion 111b. The signal terminals 115a to 115d are lined up in a row from back to front. As a result, the signal terminal 115a, ground terminal 112a, signal terminal 115b, ground terminal 112b, signal terminal 115c, ground terminal 112c, signal terminal 115d, and ground terminal 112d are lined up in this order from back to front.

[0049] Portions of the signal terminals 115e to 115h are embedded in the right side of the frame portion 111b. Therefore, the signal terminals 115e to 115h are located to the right of the signal terminals 115a to 115d. The signal terminals 115e to 115h are arranged in a row from back to front. The ground terminal 112e, the signal terminal 115e, the ground terminal 112f, the signal terminal 115f, the ground terminal 112g, the signal terminal 115g, the ground terminal 112h, and the signal terminal 115h are arranged in this order from back to front. The signal terminals 115a, the signal terminal 115e, the signal terminal 115b, the signal terminal 115f, the signal terminal 115c, the signal terminal 115g, the signal terminal 115d, and the signal terminal 115h are arranged in this order from back to front. The signal terminals 115a to 115h are made by bending a rod-shaped metal member, and are made of a copper-based material such as phosphor bronze.

[0050] In the second connector 110 described above, the second connector 110 is mounted on a second circuit board (not shown) so that the bottom surface of the resin body member 111 faces the second circuit board. More specifically, portions of the ground terminals 112a-112h, portions of the contact terminals 114f and 114b, and portions of the signal terminals 115a-115h are exposed from the top surface of the resin body member 111. Solder is then applied to each of these portions. As a result, the ground terminals 112a-112h, the contact terminals 114f and 114b, and the signal terminals 115a-115h are electrically connected to electrodes of the second circuit board.

[0051] The frame 111b of the second connector 110 is inserted into the area surrounded by the frame 11b of the first connector 10. At this time, the protrusion 11a of the first connector 10 is inserted into the area surrounded by the frame 111b of the second connector 110. As a result, the first ground terminals 12a-12d come into contact with the ground terminals 112a-112d, respectively. The second ground terminals 13a-13d come into contact with the ground terminals 112e-112h, respectively. The contact terminal 14 comes into contact with the contact terminals 114f and 114b. The first signal terminals 15a-15d come into contact with the signal terminals 115a-115d, respectively. The second signal terminals 16a-16d come into contact with the signal terminals 115e-115h, respectively.

[0052] [effect] The first connector 10 can improve isolation between high-frequency signals. More specifically, the second proximity portion PS2 has a portion located above the first proximity portion PS1. Furthermore, the first proximity portion PS1 has a portion located below the second proximity portion PS2. This reduces the area over which the third signal terminal 150 and the fourth signal terminal 160 face each other. This reduces the capacitance formed between the third signal terminal 150 and the fourth signal terminal 160. This suppresses electromagnetic coupling between the third signal terminal 150 and the fourth signal terminal 160, improving isolation between the high-frequency signals input / output to / from the third signal terminal 150 and the high-frequency signals input / output to / from the fourth signal terminal 160. As a result, the first connector 10 can improve isolation between high-frequency signals.

[0053] The first connector 10 can further improve isolation between high-frequency signals. More specifically, the upper end of the first proximity portion PS1 is located lower than the lower end of the second proximity portion PS2. This prevents the first proximity portion PS1 from facing the second proximity portion PS2. That is, the right principal surface of the third portion P3 of each of the first signal terminals 15a to 15d and the left principal surface of the sixth portion P6 of each of the second signal terminals 16a to 16d do not face each other. Furthermore, the distance between the third signal terminal 150 and the fourth signal terminal 160 can be increased. This can further improve isolation between high-frequency signals inputted / outputted to / from the third signal terminal 150 and the fourth signal terminal 160. As a result, the first connector 10 can further improve isolation between high-frequency signals.

[0054] The first connector 10 can further improve isolation between high-frequency signals. More specifically, when viewed from the right, one of the second signal terminals 16a to 16d is located between two adjacent first signal terminals. Furthermore, when viewed from the left, one of the first signal terminals 15a to 15d is located between two adjacent second signal terminals. Therefore, the first proximity portion PS1 and the second proximity portion PS2 are not aligned on a straight line parallel to the left-right direction when viewed from below. That is, the right principal surface of the third portion P3 of each of the first signal terminals 15a to 15d and the left principal surface of the sixth portion P6 of each of the second signal terminals 16a to 16d do not face each other. Furthermore, the distance between the third signal terminal 150 and the fourth signal terminal 160 can be increased. Therefore, isolation between the high-frequency signals input / output to / from the third signal terminal 150 and the high-frequency signals input / output to / from the fourth signal terminal 160 can be further improved. As a result, the first connector 10 can further improve isolation between high frequency signals.

[0055] [First Modification] The third signal terminal 150 and the fourth signal terminal 160 according to a first modified example of the present invention will be described below with reference to the drawings. Fig. 12 is a view of the third signal terminal 150 and the fourth signal terminal 160 according to the first modified example as viewed from the front. Note that with regard to the third signal terminal 150 and the fourth signal terminal 160 according to the first modified example, only the differences from the third signal terminal 150 and the fourth signal terminal 160 according to the first embodiment will be described, and the rest will be omitted.

[0056] The third signal terminal 150 and the fourth signal terminal 160 according to the first modified example differ from the third signal terminal 150 and the fourth signal terminal 160 according to the first embodiment in that the upper end of the third portion P3 is located above the lower end of the sixth portion P6, as shown in FIG. 12.

[0057] The first proximity portion PS1 and the second proximity portion PS2 are aligned on a straight line L that is parallel to the left-right direction when viewed from the front.

[0058] The vertical distance D2 between the vertical center O1 of the first proximity portion PS1 and the vertical center O2 of the second proximity portion PS2 is greater than or equal to 1 / 3 and less than or equal to 2 times the vertical distance D1 between the vertical center O1 of the first proximity portion PS1 and the lower end of the first proximity portion PS1.

[0059] The first connector 10a including the third signal terminal 150 and the fourth signal terminal 160 according to the first modification as described above also achieves the same effects as the first connector 10. Furthermore, the first connector 10a can improve isolation between high-frequency signals and prevent the first and second connectors from becoming larger in size in the vertical direction. More specifically, the greater the vertical distance between the first proximity portion PS1 and the second proximity portion PS2, the greater the isolation between the high-frequency signals input / output to / from the third signal terminal 150 and the high-frequency signals input / output to / from the fourth signal terminal 160. On the other hand, the greater the vertical distance between the first proximity portion PS1 and the second proximity portion PS2, the larger the first connector becomes in size in the vertical direction. If the vertical size of the second connector remains unchanged, there is a risk that the third signal terminal 150 and the signal terminal 115a will not make contact when the first and second connectors are connected. Therefore, the second connector also needs to be larger in size in the vertical direction. Therefore, the vertical distance D2 between the vertical center O1 of the first proximity portion PS1 and the vertical center O2 of the second proximity portion PS2 is between one-third and two times the vertical distance D1 between the vertical center O1 of the first proximity portion PS1 and the lower end of the first proximity portion PS1. This makes it possible to improve isolation between high-frequency signals input / output to / from the third signal terminal 150 and high-frequency signals input / output to / from the fourth signal terminal 160 while suppressing an increase in the vertical size of each of the first and second connectors. As a result, the first connector 10a improves isolation between high-frequency signals and suppresses an increase in the vertical size of each of the first and second connectors.

[0060] [Second Modification] A first connector 10b according to a second modified example of the present invention will be described below with reference to the drawings. FIG. 13 is a front view of a third signal terminal 150a and a fourth signal terminal 160a according to the second modified example. FIG. 14 is a front view of a third signal terminal 150b and a fourth signal terminal 160b according to the second modified example. FIG. 15 is a front view of a third signal terminal 150c and a fourth signal terminal 160c according to the second modified example. FIG. 16 is a front view of a third signal terminal 150d and a fourth signal terminal 160d according to the second modified example. FIG. 17 is a downward view of the protrusion 11a, the third signal terminals 150a-150d, and the fourth signal terminals 160a-160d according to the second modified example. Note that, with regard to the first connector 10b according to the second modified example, only the differences from the first connector 10 according to the first embodiment will be described, and the rest will be omitted.

[0061] As shown in Figures 13 to 16, the first connector 10b of the second modified example differs from the first connector 10 of the first embodiment in that the positional relationship between the center in the vertical direction of the right main surface of the third portion P3 and the center in the vertical direction of the left main surface of the sixth portion P6 varies depending on the combination of the third signal terminal and the fourth signal terminal.

[0062] In this modification, the first signal terminals 15a to 15d are defined as third signal terminals 150a to 150d. As a result, the second signal terminals 16a to 16d become fourth signal terminals 160a to 160d. The fourth signal terminals 160a to 160d correspond to the third signal terminals 150a to 150d, respectively.

[0063] Furthermore, a combination of the third signal terminal and the fourth signal terminal in which the center O1 of the first proximity portion PS1 in the vertical direction is located below the center O2 of the second proximity portion PS2 in the vertical direction is defined as a first combination C1. Furthermore, a combination of the third signal terminal and the fourth signal terminal in which the center O1 of the first proximity portion PS1 in the vertical direction is located above the center O2 of the second proximity portion PS2 in the vertical direction is defined as a second combination C2.

[0064] As shown in FIG. 13 , the vertical length of the fourth portion P4 of the second signal terminal 16a (fourth signal terminal 160a) is longer than the vertical length of the first portion P1 of the first signal terminal 15a (third signal terminal 150a). As a result, the vertical center of the right principal surface of the third portion P3 of the first signal terminal 15a (third signal terminal 150a) is located below the vertical center of the left principal surface of the sixth portion P6 of the second signal terminal 16a (fourth signal terminal 160a). In other words, the vertical center O1 of the first neighboring portion PS1 of the third signal terminal 150a is located below the vertical center O2 of the second neighboring portion PS2 of the fourth signal terminal 160a. Therefore, the combination of the third signal terminal 150a and the fourth signal terminal 160a is a first combination C1.

[0065] On the other hand, as shown in FIG. 14, the vertical length of the fourth portion P4 of the second signal terminal 16b (fourth signal terminal 160b) is shorter than the vertical length of the first portion P1 of the first signal terminal 15b (third signal terminal 150b). As a result, the vertical center of the right principal surface of the third portion P3 of the first signal terminal 15b (third signal terminal 150b) is located above the vertical center of the left principal surface of the sixth portion P6 of the second signal terminal 16b (fourth signal terminal 160b). In other words, the vertical center O1 of the first neighboring portion PS1 of the third signal terminal 150b is located above the vertical center O2 of the second neighboring portion PS2 of the fourth signal terminal 160b. Therefore, the combination of the third signal terminal 150b and the fourth signal terminal 160b is the second combination C2.

[0066] 15, the vertical length of the fourth portion P4 of the second signal terminal 16c (fourth signal terminal 160c) is longer than the vertical length of the first portion P1 of the first signal terminal 15c (third signal terminal 150c). As a result, the vertical center of the right principal surface of the third portion P3 of the first signal terminal 15c (third signal terminal 150c) is located below the vertical center of the left principal surface of the sixth portion P6 of the second signal terminal 16c (fourth signal terminal 160c). In other words, the vertical center O1 of the first proximity portion PS1 of the third signal terminal 150c is located below the vertical center O2 of the second proximity portion PS2 of the fourth signal terminal 160c. Therefore, the combination of the third signal terminal 150c and the fourth signal terminal 160c is a first combination C1.

[0067] 16, the vertical length of the fourth portion P4 of the second signal terminal 16d (fourth signal terminal 160d) is shorter than the vertical length of the first portion P1 of the first signal terminal 15d (third signal terminal 150d). As a result, the vertical center of the right principal surface of the third portion P3 of the first signal terminal 15d (third signal terminal 150d) is located above the vertical center of the left principal surface of the sixth portion P6 of the second signal terminal 16d (fourth signal terminal 160d). In other words, the vertical center O1 of the first proximity portion PS1 of the third signal terminal 150d is located above the vertical center O2 of the second proximity portion PS2 of the fourth signal terminal 160d. Therefore, the combination of the third signal terminal 150d and the fourth signal terminal 160d is the second combination C2.

[0068] As shown in FIG. 17, the first combination C1 and the second combination C2 are arranged alternately in the front-rear direction.

[0069] The first connector 10b described above also achieves the same effects as the first connector 10. Furthermore, the first connector 10b can more firmly hold the second connector to the first connector. The first combination C1 will be described using the third signal terminal 150a and the fourth signal terminal 160a as an example. The second combination C2 will be described using the third signal terminal 150b and the fourth signal terminal 160b as an example. In the first combination C1, the vertical center O1 of the first proximity portion PS1 is located below the vertical center O2 of the second proximity portion PS2. As a result, the vertical contact distance between the third signal terminal 150a and the signal terminal 115a is smaller than the vertical contact distance between the fourth signal terminal 160a and the signal terminal 115e. Therefore, the frictional force between the third signal terminal 150a and the signal terminal 115a is smaller than the frictional force between the fourth signal terminal 160a and the signal terminal 115e. Here, the frictional force is a force included in the force holding the first connector to the second connector. In the second combination C2, the vertical center O1 of the first proximity portion PS1 is located above the vertical center O2 of the second proximity portion PS2. As a result, the vertical contact distance between the third signal terminal 150b and the signal terminal 115b is shorter than the vertical contact distance between the fourth signal terminal 160b and the signal terminal 115f. Therefore, the frictional force between the third signal terminal 150b and the signal terminal 115b is greater than the frictional force between the fourth signal terminal 160b and the signal terminal 115f. Therefore, in the first connector 10b, the first combination C1 and the second combination C2 are arranged alternately in the front-to-rear direction. This prevents the frictional force from concentrating in one part of the first connector and reduces the difference between the total frictional force in the left part of the first connector and the total holding force in the right part of the first connector. As a result, the first connector 10b can hold the second connector more firmly to the first connector.

[0070] Furthermore, the first connector 10b can prevent the first signal terminals from coming off the resin body member. More specifically, when viewed from the right, one of the first ground terminals 12a-12d is located between two adjacent first signal terminals. This ensures a sufficient distance between the first signal terminals 15a-15d, improving isolation between high-frequency signals input to and output from the first signal terminals 15a-15d. Therefore, the length of the third portion P3 in the front-rear direction is longer than the length of the second portion P2 in the front-rear direction. This allows the resin body member 11 to be located above the third portion P3. Therefore, when a force is applied to the first signal terminals, the third portion P3 is caught on the resin body member 11. As a result, the first connector 10b can prevent the first signal terminals from coming off the resin body member.

[0071] Furthermore, the first connector 10b can prevent the second signal terminals from coming off the resin body member. More specifically, when viewed from the right, one of the second ground terminals 13a-13d is located between two adjacent second signal terminals. This ensures a sufficient distance between the second signal terminals 16a-16d, improving isolation between high-frequency signals input to and output from the second signal terminals 16a-16d. Therefore, the length of the sixth portion P6 in the front-rear direction is longer than the length of the fifth portion P5 in the front-rear direction. This positions the resin body member 11 above the sixth portion P6. Therefore, when a force is applied to the second signal terminals, the sixth portion P6 is caught by the resin body member 11. As a result, the first connector 10b can prevent the second signal terminals from coming off the resin body member.

[0072] [Other embodiments] The first connector according to the present invention is not limited to first connectors 10, 10a, and 10b, and can be modified within the scope of the invention. Furthermore, the structures of first connectors 10, 10a, and 10b may be combined in any manner.

[0073] It is sufficient that there are one or more first signal terminals, and one or more second signal terminals.

[0074] The number of third signal terminals may be one or more, and the number of fourth signal terminals may be one or more.

[0075] The first signal terminals 15a to 15d do not have to have the same shape as one another, and the second signal terminals 16a to 16d do not have to have the same shape as one another.

[0076] The length of the third portion P3 in the front-rear direction may be equal to or less than the length of the second portion P2 in the front-rear direction.

[0077] The length of the sixth portion P6 in the front-rear direction may be equal to or less than the length of the fifth portion P5 in the front-rear direction.

[0078] Note that, when viewed from the right, any one of first ground terminals 12a to 12d does not have to be located between two adjacent first signal terminals, and, when viewed from the left, any one of second ground terminals 13a to 13d does not have to be located between two adjacent second signal terminals.

[0079] The length of the third portion P3 in the front-rear direction does not have to be longer than the length of the second portion P2 in the front-rear direction. Also, the length of the sixth portion P6 in the front-rear direction does not have to be longer than the length of the fifth portion P5 in the front-rear direction.

[0080] Note that the first connectors 10, 10a, 10b do not necessarily have to include the first ground terminals 12a-12d and the second ground terminals 13a-13d. If the first connectors 10, 10a, 10b include first ground terminals, it is sufficient that there be one or more first ground terminals. If the first connectors 10, 10a, 10b include second ground terminals, it is sufficient that there be one or more second ground terminals.

[0081] The first signal terminals 15a to 15d and the second signal terminals 16a to 16d may have the same shape as each other, as long as the second proximity portion PS2 has a portion located above the first proximity portion PS1 and the first proximity portion PS1 has a portion located below the second proximity portion PS2.

[0082] The right principal surface of the third portion P3 may have a portion located higher than the left principal surface of the sixth portion P6. Therefore, the first proximity portion PS1 may have a portion located higher than the second proximity portion PS2. In this case, the left principal surface of the sixth portion P6 may have a portion located lower than the right principal surface of the third portion P3. Therefore, the second proximity portion PS2 may have a portion located lower than the first proximity portion PS1.
