Description

Technical Field

[0001] This invention relates to connectors and connector assemblies. Background Technology

[0002] As an invention concerning conventional connectors, a female connector as described in Patent Document 1 is known, for example. The female connector described in Patent Document 1 is used for transmitting high-frequency signals. The female connector described in Patent Document 1 includes a plurality of internal terminals. The plurality of internal terminals are arranged along their long side direction. In the long side direction, the internal terminals are opposite each other. A protrusion is formed on a portion of each internal terminal. The length of the protrusion in the long side direction is longer than the length of the portion of the internal terminal other than the protrusion in the long side direction (see reference). Figure 4 ).

[0003] Patent Document 1: International Publication No. 2019 / 220930

[0004] With the aforementioned internal terminal configuration, in the longer portion along the long side, the distance between the portion opposite the adjacent internal terminal becomes shorter, resulting in a larger parasitic capacitance between these portions. Conversely, in the shorter portion along the long side, the distance between the portion opposite the adjacent internal terminal becomes longer, resulting in a smaller parasitic capacitance between these portions. Thus, if the parasitic capacitance between the portions opposite the adjacent internal terminals varies depending on their location, impedance mismatch occurs, potentially leading to increased return loss, particularly in applications processing high-frequency signals. Summary of the Invention

[0005] Therefore, the object of the present invention is to provide a connector and connector assembly that can equalize the parasitic capacitance formed between terminals and reduce return loss.

[0006] One embodiment of the present invention relates to a connector comprising:

[0007] The first main component; and

[0008] Multiple first connection terminals, supported on the aforementioned first main body component, are arranged at predetermined intervals along a first straight line parallel to the first direction.

[0009] At least one of the aforementioned first connection terminals is a first signal terminal.

[0010] The aforementioned first signal terminal includes:

[0011] The mounting portion extends, at least a portion of which extends in a second direction orthogonal to the first direction described above;

[0012] The rear portion is connected to the aforementioned mounting portion and extends upward in a third direction orthogonal to the aforementioned first direction and the aforementioned second direction;

[0013] The top portion is connected to the aforementioned back portion and has a first portion extending in the aforementioned second direction; and

[0014] The contact portion, connected to the aforementioned top surface portion, is located at a different position from the aforementioned back surface portion in the aforementioned second direction, and overlaps with the aforementioned back surface portion when viewed in the aforementioned second direction.

[0015] The aforementioned mounting section is electrically connected to the electrodes of other components that are different from the aforementioned connector.

[0016] The aforementioned contact portion contacts the second signal terminal of a second connector that is different from the aforementioned connector.

[0017] The aforementioned back portion has a wide portion that is wider in the first direction compared to the width of the first portion in the first direction.

[0018] The width of at least a portion of the contact portion in the first direction is wider than the width of the first portion in the first direction, or the length of at least a portion of the contact portion in the second direction is longer than the thickness of the first portion in the third direction.

[0019] According to the connectors and connector assemblies of the present invention, parasitic capacitances formed between terminals can be equalized to reduce return loss. Attached Figure Description

[0038] [First Implementation Method]

[0039] The following is a reference to the appendix. Figure 1 The connector group 1, which includes the first connector 10 according to the first embodiment of the present invention, will be described below. Figure 1 This is a perspective view of connector group 1 when the first connector 10 and the second connector 110 are not connected.

[0040] like Figure 1 As shown, the direction from the second connector 110 toward the first connector 10 is defined as the downward direction. Conversely, the opposite direction is defined as the upward direction. The upward and downward directions (vertical and horizontal directions) correspond to the "third direction" of this invention.

[0041] Connector group 1 is used to connect two components. A component may be, for example, a circuit board. Figure 1As shown, connector group 1 includes a first connector 10 and a second connector 110.

[0042] [Construction of the first connector 10]

[0043] While referring to the appendix Figure 1 The structure of the first connector 10 will be described below. Figure 2 This is a perspective view of the first connector 10. Figure 3 This is a three-dimensional view of the first main component 11. Figure 4 This is a perspective view of the first contact terminal 12, the first signal terminals 13a to 13d, and the first grounding terminals 14a to 14c. Figure 5 This is a three-dimensional view of the first signal terminal 13a. Figure 6 This is a cross-sectional view of the first signal terminal 13a.

[0044] like Figure 2 As shown, the direction in which the first signal terminals 13a to 13d are arranged in sequence is defined as the forward direction. The opposite direction of the forward direction is defined as the backward direction. The forward and backward directions are orthogonal to the downward and upward directions. The forward and backward directions (front-back directions) correspond to the "first direction" of the present invention. The direction in which the protrusion 11c and the first signal terminals 13a are arranged in sequence is defined as the right direction. The opposite direction of the right direction is defined as the left direction. The right and left directions are orthogonal to the downward and forward directions. The left and right directions (left-right directions) correspond to the "second direction" of the present invention. However, the downward, upward, forward, backward, right, and left directions in this specification are defined for ease of explanation and may not be consistent with the downward, upward, forward, backward, right, and left directions used when the first connector 10 is in use. In addition, the downward and upward directions, the forward and backward directions, and the right and left directions may be interchanged in the various figures.

[0045] like Figure 2 As shown, the first connector 10 includes a first main body component 11, a first contact terminal 12, first signal terminals 13a-13d, and first ground terminals 14a-14c. Furthermore, the first signal terminals 13a-13d can also be ground terminals connected to a ground potential or power terminals connected to a power supply potential, and the first ground terminals 14a-14c can also be power terminals connected to either the signal terminals or the power supply potential. The first signal terminals 13a-13d and the first ground terminals 14a-14c correspond to the "multiple first connection terminals" of the present invention. The "multiple first connection terminals" of the present invention only need to include at least one first signal terminal. When the first ground terminals 14a-14c are power terminals, the first ground terminals 14a-14c correspond to the "first power terminal" of the present invention.

[0046] like Figure 3 As shown, the first main body component 11 includes a frame portion 11a, a bottom portion 11b, and a protrusion portion 11c. In this embodiment, the material of the first main body component 11 is resin. However, the material of the first main body component 11 is not limited to resin.

[0047] When viewed in the vertical direction, the frame portion 11a has an annular shape surrounding the first signal terminals 13a-13d, the first ground terminals 14a-14c, and the protrusion 11c. The frame portion 11a has a left and right side extending in the front-back direction, and a front and rear side extending in the left-right direction.

[0048] When viewed in the vertical direction, the bottom 11b blocks part of the lower surface of the area surrounded by the frame 11a.

[0049] A protrusion 11c is provided at the bottom 11b. The protrusion 11c protrudes upward from the bottom 11b. Furthermore, the protrusion 11c has a shape extending in the front-rear direction. In this embodiment, the two ends of the protrusion 11c in the front-rear direction are connected to the front and rear sides of the frame portion 11a, respectively. A plurality of recessed grooves are formed across the right surface of the protrusion 11c and the bottom 11b. A portion of each of the first signal terminals 13a-13d and the first ground terminals 14a-14c enters one of the plurality of recessed grooves. Alternatively, the two ends of the protrusion 11c in the front-rear direction may not be connected to the front and rear sides of the frame portion 11a, respectively.

[0050] In this embodiment, the first contact terminal 12 is connected to the ground potential. For example... Figure 4 As shown, when viewed vertically, the first contact terminal 12 has a ring shape surrounding the first signal terminals 13a-13d and the first ground terminals 14a-14c. The first contact terminal 12 is supported on the frame portion 11a of the first main body component 11. Furthermore, the first contact terminal 12 covers a portion of the frame portion 11a of the first main body component 11. The first contact terminal 12 is manufactured by bending a plate-shaped metal component. In this embodiment, the material of the first contact terminal 12 is a copper-based material such as copper phosphate. Furthermore, the first contact terminal 12 is not limited to being connected to a ground potential; it can also be connected to a power source. Additionally, the material of the first contact terminal 12 is not limited to copper-based materials such as copper phosphate.

[0051] High-frequency signals are input and output at the first signal terminals 13a to 13d respectively. The first signal terminals 13a to 13d are arranged at predetermined intervals on a first straight line L1 parallel to the front-back direction.

[0052] In this embodiment, the first grounding terminals 14a to 14c are respectively connected to the grounding potential. The first grounding terminals 14a to 14c are arranged at predetermined intervals on the first straight line L1.

[0053] The first signal terminals 13a-13d and the first ground terminals 14a-14c are arranged at predetermined intervals on the first straight line L1. In this embodiment, the first ground terminals are located between adjacent first signal terminals on the first straight line L1. Alternatively, the first signal terminals may not be located between adjacent first ground terminals on the first straight line L1.

[0054] The construction of the first signal terminals 13a to 13d and the first ground terminals 14a to 14c will be described in detail using the first signal terminal 13a as an example. Furthermore, the first signal terminals 13b to 13d and the first ground terminals 14a to 14c each have the same shape as the first signal terminal 13a, therefore their descriptions are omitted.

[0055] The first signal terminal 13a is manufactured by bending a plate-shaped metal part. In this embodiment, the material of the first signal terminal 13a is a copper-based material such as copper phosphate. However, the material of the first signal terminal 13a is not limited to copper-based materials such as copper phosphate.

[0056] like Figure 5 As shown, in this embodiment, the first signal terminal 13a includes a first mounting portion MP1, a back portion BP, a top portion TP, and a first contact portion CP1. In this embodiment, the thickness T1 of the first signal terminal 13a is uniform. However, the thickness T1 of the first signal terminal 13a may also be non-uniform.

[0057] The first mounting portion MP1 extends in the left-right direction. More specifically, the first mounting portion MP1 has an upper surface and a lower surface arranged in the vertical direction. When the first connector 10 is mounted on a first circuit board (not shown) disposed below the first connector 10, the lower surface of the first mounting portion MP1 is electrically connected to the external electrode of the first circuit board. The lower surface of the first mounting portion MP1 is fixed to the external electrode of the first circuit board, for example, by solder (not shown). Furthermore, the first mounting portion MP1 only needs to have at least a portion extending in the left-right direction. Moreover, the object for mounting the first connector 10 is not limited to the first circuit board. The first circuit board corresponds to the "other components" of the present invention.

[0058] The back portion BP is connected to the first mounting portion MP1 and the top portion TP. In this embodiment, the back portion BP extends vertically from the left end of the first mounting portion MP1. The back portion BP has a wide portion WP. The wide portion WP is pressed into a concave groove formed across the right surface of the protrusion 11c and the bottom 11b. Thus, the wide portion WP is supported on the first main body member 11. Therefore, the first signal terminal 13a is supported on the first main body member 11. Alternatively, the back portion BP may also extend vertically from the right end of the first mounting portion MP1.

[0059] The top surface portion TP has a first end E1 and a second end E2. The first end E1 of the top surface portion TP is connected to the upper end of the back surface portion BP. The second end E2 of the top surface portion TP is connected to the first contact portion CP1. In addition, the top surface portion TP has a first portion P1 extending in the left-right direction. The width WP1 of the first portion P1 in the front-back direction is narrower than the width WWP of the wide portion WP in the front-back direction. In other words, the width WWP of the wide portion WP in the front-back direction is wider than the width WP1 of the first portion P1 in the front-back direction.

[0060] The first contact portion CP1 is connected to the second end E2 of the top portion TP. The first contact portion CP1 is located at a position different from the back portion BP in the left-right direction. When viewed in the left-right direction, the first contact portion CP1 overlaps with the back portion BP. In this embodiment, the first contact portion CP1 has a first protrusion PP1 and a second protrusion PP2. The second protrusion PP2 has a shape that is symmetrical to the first protrusion PP1 front-back.

[0061] The first protrusion PP1 has a second portion P2 extending in a forward direction and a third portion P3 extending to the left from the front end of the second portion P2. Furthermore, the third portion P3 corresponds to the "fourth portion" of the present invention.

[0062] The second protrusion PP2 has a fourth portion P4 extending rearward and a fifth portion P5 extending to the left from the rear end of the fourth portion P4. Furthermore, the fourth portion P4 corresponds to the "third portion" of the present invention.

[0063] like Figure 5 as well as Figure 6 As shown, the first protrusion PP1 has a second portion P2, and the second protrusion PP2 has a fourth portion P4, so that the width WCP in the front-back direction of at least a portion of the first contact portion CP1 is wider than the width WP1 in the front-back direction of the first portion P1.

[0064] like Figure 6As shown, the left-right length LP32 of the third part P3 is longer than the vertical thickness TP1 of the first part P1. Furthermore, the left-right length LP52 of the fifth part P5 is longer than the vertical thickness TP1 of the first part P1. Therefore, at least a portion of the first contact portion CP1 has a left-right length longer than the vertical thickness TP1 of the first part P1.

[0065] In this embodiment, the vertical length LP33 of the third portion P3 is longer than the vertical thickness TP1 of the first portion P1. Furthermore, the vertical length LP53 of the fifth portion P5 is longer than the vertical thickness TP1 of the first portion P1. Additionally, the vertical length LP33 of the third portion P3 may be less than or equal to the vertical thickness TP1 of the first portion P1. Similarly, the vertical length LP53 of the fifth portion P5 may be less than or equal to the vertical thickness TP1 of the first portion P1.

[0066] [Construction of the second connector 110]

[0067] While referring to the appendix Figure 1 The construction of the second connector 110 will be described below. Figure 7 This is a 3D view of the second connector 110. Figure 8 This is a three-dimensional view of the second main component 111. Figure 9 This is a perspective view of the second contact terminal 112, the second signal terminals 113a to 113d, and the second grounding terminals 114a to 114c. Figure 10 This is a perspective view of the second signal terminal 113a. Furthermore, as... Figures 7 to 10 As shown, the second connector 110 has a shape that is approximately symmetrical to the first connector 10 in both the left and right and in both the top and bottom. Therefore, only the parts that are different from the first connector 10 will be described and omitted thereafter.

[0068] like Figure 7 As shown, the second connector 110 includes a second main body component 111, a second contact terminal 112, second signal terminals 113a-113d, and second ground terminals 114a-114c. Furthermore, the second signal terminals 113a-113d can each be either ground terminals connected to a ground potential or power terminals connected to a power supply potential, and the second ground terminals 114a-114c can each be either signal terminals or power terminals connected to a power supply potential. It is sufficient that at least one of the second signal terminals 113a-113d and the second ground terminals 114a-114c is a signal terminal. When the second ground terminals 114a-114c are power terminals, they correspond to the "second power terminal" of this invention.

[0069] like Figure 8As shown, the second main body component 111 includes a frame portion 111a, a bottom portion 111b, and a protrusion portion 111c. In this embodiment, the material of the second main body component 111 is resin. Furthermore, the two ends of the protrusion portion 111c in the front-rear direction may not be connected to the front and rear sides of the frame portion 111a, respectively. Additionally, the material of the second main body component 111 is not limited to resin.

[0070] In this embodiment, the second contact terminal 112 is connected to a ground potential. The second contact terminal 112 is manufactured by bending a plate-shaped metal component. In this embodiment, the material of the second contact terminal 112 is a copper-based material such as copper phosphate. Furthermore, the second contact terminal 112 is not limited to being connected to a ground potential; it can also be connected to a power source. Additionally, the material of the second contact terminal 112 is not limited to copper-based materials such as copper phosphate.

[0071] The second signal terminals 113a-113d and the second ground terminals 114a-114c have the same shape as the first signal terminal 13a. The second signal terminals 113a-113d and the second ground terminals 114a-114c are configured to be symmetrical about the left and right, and vertically, with respect to the first signal terminals 13a-13d and the first ground terminals 14a-14c when the first connector 10 and the second connector 110 are connected. High-frequency signals are input and output at the second signal terminals 113a-113d. Figure 9 As shown, the second signal terminals 113a to 113d are arranged at predetermined intervals on a third straight line L3 that is parallel to the front-back direction.

[0072] In this embodiment, the second grounding terminals 114a to 114c are respectively connected to the grounding potential. The second grounding terminals 114a to 114c are arranged at predetermined intervals on the third straight line L3.

[0073] In this embodiment, the second grounding terminal is located between adjacent second signal terminals on the third straight line L3. Alternatively, the second signal terminals are located between adjacent second grounding terminals on the third straight line L3. Furthermore, the second grounding terminal may not be located between adjacent second signal terminals on the third straight line L3. Additionally, the first signal terminal may not be located between adjacent second grounding terminals on the third straight line L3.

[0074] The second signal terminal 113a is manufactured by bending a plate-shaped metal component. In this embodiment, the material of the second signal terminal 113a is a copper-based material such as copper phosphate. However, the material of the second signal terminal 113a is not limited to copper-based materials such as copper phosphate.

[0075] like Figure 10As shown, in this embodiment, the second signal terminal 113a includes a second mounting portion MP2, a back portion BP, a top portion TP, and a second contact portion CP2. In this embodiment, the thickness T2 of the second signal terminal 113a is uniform. However, the thickness T2 of the second signal terminal 113a may also be non-uniform.

[0076] When the second connector 110 is mounted on a second circuit board (not shown) disposed above the second connector 110, the upper surface of the second mounting portion MP2 of the second signal terminal 113a is electrically connected to the external electrode of the second circuit board. The upper surface of the second mounting portion MP2 of the second signal terminal 113a is fixed to the external electrode of the second circuit board, for example, by solder (not shown).

[0077] [Construction of Connector Group 1]

[0078] While referring to the appendix Figure 1 The structure of connector group 1 will be described below. Figure 11 This is a perspective view showing the connection between the first signal terminal 13a and the second signal terminal 113a.

[0079] like Figure 1 As shown, when the second connector 110 is viewed vertically, the first main body component 11 of the first connector 10 is inserted into the area surrounded by the frame portion 111a of the second connector 110. The first connector 10 is connected to the second connector 110 in the vertical direction. When the first connector 10 and the second connector 110 are connected, the second connector 110 is located above the first connector 10. At this time, the frame portions 11a of the first connector 10 and the frame portions 111a of the second connector 110 do not overlap when viewed vertically. In addition, the protrusions 11c of the first connector 10 and the protrusions 111c of the second connector 110 do not overlap when viewed vertically.

[0080] When connecting the first connector 10 to the second connector 110, the first signal terminals 13a-13d and the first ground terminals 14a-14c of the first connector 10 are respectively connected to the second signal terminals 113a-113d and the second ground terminals 114a-114c of the second connector 110. When connecting the first connector 10 to the second connector 110, for example, as... Figure 11As shown, the first contact portion CP1 of the first signal terminal 13a contacts the second contact portion CP2 of the second signal terminal 113a. At this time, the first contact portion CP1 and the second contact portion CP2 of the second signal terminal 113a make contact at a point on the right surface of the first contact portion CP1. In addition, the first contact portion CP1 is pressed to the left by the second contact portion CP2, thereby causing the first contact portion CP1 to elastically deform to the left relative to the second contact portion CP2. By balancing the leftward force received from the second contact portion CP2 with the rightward elastic force of the first contact portion CP1, the first contact portion CP1 is supported by the second contact portion CP2. Thus, the first signal terminal 13a and the second signal terminal 113a are connected. Similarly, the first signal terminals 13b to 13d and the first ground terminals 14a to 14c are connected to the second signal terminals 113b to 113d and the second ground terminals 114a to 114c, respectively.

[0081] [Effect]

[0082] According to the first connector 10, parasitic capacitance formed between terminals can be equalized to reduce return loss. The first signal terminal 13a and the first ground terminal 14a will be described as examples. On a first straight line L1 parallel to the front-rear direction, the first signal terminal 13a is located adjacent to the first ground terminal 14a. The first signal terminal 13a includes a first mounting portion MP1, a back portion BP, a top portion TP, and a first contact portion CP1. The first contact portion CP1 is located at a different position from the back portion BP in the left-right direction. The back portion BP has a wide portion WP for pressing into a concave groove formed in the first body member 11. The top portion TP has a first portion P1 extending in the left-right direction. The width WWP of the wide portion WP in the front-rear direction is wider than the width WP1 of the first portion P1 in the front-rear direction. Therefore, the distance in the front-rear direction between the wide portion WP of the first signal terminal 13a and the first ground terminal 14a is shorter than the distance in the front-rear direction between the first portion P1 of the first signal terminal 13a and the first ground terminal 14a. Therefore, the parasitic capacitance formed between the wide portion WP of the first signal terminal 13a and a portion of the first ground terminal 14a opposite the wide portion WP of the first signal terminal 13a in the front-back direction is relatively large. On the other hand, the parasitic capacitance formed between the top portion TP of the first signal terminal 13a and a portion of the first ground terminal 14a opposite the top portion TP of the first signal terminal 13a in the front-back direction is relatively small. Assuming that the first contact portion CP1 of the first signal terminal 13a exists only on the imaginary extension line of the top portion TP of the first signal terminal 13a, the parasitic capacitance formed between the first contact portion CP1 of the first signal terminal 13a and a portion of the first ground terminal 14a opposite the first contact portion CP1 of the first signal terminal 13a in the front-back direction also becomes smaller. In this case, because the first signal terminal 13a has a wide portion WP, the value of the parasitic capacitance formed between the first signal terminal 13a and a portion of the first ground terminal 14a due to the change in position in the left-right direction is relatively large.

[0083] However, in this embodiment, in the first connector 10, the front-rear width WCP of at least a portion of the first contact portion CP1 of the first signal terminal 13a is wider than the front-rear width WP1 of the first portion P1. Therefore, the front-rear distance between the first contact portion CP1 of the first signal terminal 13a and the first ground terminal 14a is shorter than the front-rear distance between the first portion P1 of the first signal terminal 13a and the first ground terminal 14a. Consequently, the parasitic capacitance formed between the first contact portion CP1 of the first signal terminal 13a and a portion of the first ground terminal 14a opposite to the first contact portion CP1 in the front-rear direction is larger. Therefore, the value of the parasitic capacitance formed between the first contact portion CP1 of the first signal terminal 13a and a portion of the first ground terminal 14a opposite to the first contact portion CP1 in the front-rear direction can be made close to the value of the parasitic capacitance formed between the wide portion WP of the first signal terminal 13a and the portion of the first ground terminal 14a opposite to the wide portion WP in the front-rear direction. Therefore, compared to the case where the first contact CP1 of the first signal terminal 13a exists only on the imaginary extension line of the top surface TP of the first signal terminal 13a, the change in the value of the parasitic capacitance formed between the first signal terminal 13a and a portion of the first ground terminal 14a due to changes in position in the left-right direction can be reduced. Therefore, according to the first connector 10, the parasitic capacitance formed between the terminals can be equalized. As a result, impedance mismatch can be suppressed, and return loss can be reduced.

[0084] Furthermore, in the first connector 10, at least a portion of the left-right length of the first contact portion CP1 of the first signal terminal 13a is wider than the vertical thickness TP1 of the first portion P1. Parasitic capacitance is not limited to a shorter distance between the terminals; it also increases as the area between the terminals increases. Therefore, in this case, the value of the parasitic capacitance formed between the first contact portion CP1 of the first signal terminal 13a and a portion of the first ground terminal 14a opposite the first contact portion CP1 of the first signal terminal 13a in the front-back direction is larger. Therefore, according to the first connector 10, since at least a portion of the left-right length of the first contact portion CP1 of the first signal terminal 13a is wider than the vertical thickness TP1 of the first portion P1, the parasitic capacitance formed between the terminals can also be balanced.

[0085] Furthermore, in the first connector 10, the first contact portion CP1 of the first signal terminal 13a overlaps with the back portion BP when viewed in the left-right direction. This allows the vertical length of the first signal terminal 13a to be shortened. Therefore, the vertical length of the first connector 10 can be shortened.

[0086] Furthermore, according to the first connector 10, return loss can be further reduced. More specifically, when the first signal terminals for high-frequency signal input / output are adjacent on the first straight line L1, return loss occurs due to the mutual inductance between the first signal terminals and the high-frequency signals flowing in the adjacent first signal terminals. Therefore, in the first connector 10, the first signal terminals are located between adjacent first ground terminals or first power terminals on the first straight line L1. As a result, the first ground terminals or first power terminals suppress the influence of the high-frequency signals flowing in the first signal terminals, further reducing return loss.

[0087] Furthermore, according to the first connector 10, the first signal terminal can make more reliable contact with the second signal terminal of the second connector 110. More specifically, the first protrusion PP1 of the first contact portion CP1 has a second portion P2 extending forward from the top portion TP. Additionally, the second protrusion PP2 of the first contact portion CP1 has a fourth portion P4 extending rearward from the top portion TP. In connector assembly 1, the first signal terminal contacts the second signal terminal on the right surface of the first contact portion CP1. Because the first protrusion PP1 of the first contact portion CP1 has the second portion P2, and the second protrusion PP2 of the first contact portion CP1 has the fourth portion P4, the area of ​​the right surface of the first contact portion CP1 is increased. Therefore, according to the first connector 10, the first signal terminal can make more reliable contact with the second signal terminal of the second connector 110.

[0088] Furthermore, according to the first connector 10, the parasitic capacitance formed between the terminals can be more reliably equalized. More specifically, the first protrusion PP1 of the first contact portion CP1 has a third portion P3 extending to the left from the second portion P2. Additionally, the second protrusion PP2 of the first contact portion CP1 has a fifth portion P5 extending to the left from the fourth portion P4. This increases the area of ​​the first contact portion CP1 of the first signal terminal 13a and a portion of the first ground terminal 14a facing each other in the front-rear direction. Therefore, the value of the parasitic capacitance formed between the first contact portion CP1 of the first signal terminal 13a and the portion of the first ground terminal 14a facing the first contact portion CP1 of the first signal terminal 13a in the front-rear direction can be further increased. Therefore, according to the first connector 10, the parasitic capacitance formed between the terminals can be more reliably equalized.

[0089] Furthermore, the first protrusion PP1 and the second protrusion PP2 of the first contact portion CP1 can also be pressed into the first main body component 11. In this case, the first signal terminal is more reliably supported on the first main body component 11.

[0100] High-frequency signals are input and output at the fourth signal terminals 113e to 113h, respectively. For example... Figure 13 As shown, the fourth signal terminals 113e to 113h are arranged at predetermined intervals on the fourth straight line L4, which is parallel to the front-back direction.

[0101] In this modified example, the fourth grounding terminals 114d to 114f are respectively connected to the grounding potential. The fourth grounding terminals 114d to 114f are arranged at predetermined intervals on the fourth straight line L4.

[0102] The fourth signal terminals 113e-113h and the fourth ground terminals 114d-114f are arranged at predetermined intervals on the fourth straight line L4. In this modified example, the fourth ground terminals are located between adjacent fourth signal terminals on the fourth straight line L4.
