Abstract
Description
Technical Field
[0001] The present disclosure relates to connectors. Background Art
[0002] Japanese Patent Application Publication No. 11-339921 discloses an invention of a terminal impedance adjustment method and structure. The terminal is arranged inside a connector and has a partially cut-away shape. Thus, the capacitance of the terminal can be reduced to increase the impedance.
[0003] However, in the structure disclosed in Japanese Patent Publication No. 11-339921, since the terminal is partially cut off in the width direction of the terminal, when mating with another connector, the contact area with the terminal of the mating connector cannot be fully ensured, or the terminal of the mating connector is embedded in the cut-off portion of the terminal, and there is a possibility that the electrical conduction state cannot be ensured. Therefore, the technology involved in Japanese Patent Publication No. 11-339921 still has room for improvement in this regard. Summary of the invention
[0004] The present disclosure achieves a connector which is excellent in connection reliability with a mating terminal and can increase the impedance of the terminal.
[0005] The first mode of the present disclosure is a connector, comprising: a first connector, having a fitting portion and a first terminal arranged in the fitting portion; and a second connector, having: an fitted portion, which can be fitted in the fitting portion of the first connector; and a second terminal, which is arranged in the fitted portion and extends along the fitting direction and is electrically in contact with the first terminal when the fitted portion is fitted in the fitting portion of the first connector, and the second terminal is formed with a wide portion on the front end side of the fitted portion, and the dimension of the wide portion in the in-plane direction of the surface of the second terminal in contact with the first terminal and in a direction orthogonal to the fitting direction of the fitted portion is set to be larger than that of a normal portion, and the first terminal is in contact with the wide portion of the second terminal from the state where the fitted portion of the second connector begins to fit in the fitting portion of the first connector to the state where the fitted portion cannot be further fitted.
[0006] According to the first method described above, a wide portion is formed in the second terminal provided in the engaged portion of the second connector. The wide portion is provided on the front end side of the engaged portion of the second connector in the second terminal, and the dimension in the in-plane direction of the surface in contact with the first terminal in the second terminal and in the direction orthogonal to the engagement direction of the engaged portion with the engaging portion of the first connector (hereinafter referred to as the "width direction") is set to be larger than the width direction dimension of the ordinary portion. In addition, from the state where the engaged portion of the second connector begins to engage with the engaging portion of the first connector to the state where the engaged portion cannot be further engaged, the first terminal contacts the wide portion of the second terminal. Therefore, the first terminal does not contact the ordinary portion in the second terminal, and therefore, with respect to the width direction dimension of the ordinary portion, there is no need to consider the contact area with the first terminal, etc. Therefore, in order to increase the impedance, the width direction dimension of the ordinary portion can be reduced.
[0007] Furthermore, when the engaged portion of the second connector cannot be further engaged with the engaging portion of the first connector, the first terminal contacts the wide portion of the second terminal whose width dimension is larger than the normal portion, thereby easily ensuring the contact area. In other words, the electrical conduction state can be ensured.
[0008] The second mode of the present disclosure is a connector. In the above-mentioned first mode, a guiding inclined portion is provided on the first terminal, and the guiding inclined portion is inclined from the first terminal contact portion which is the portion in contact with the second terminal in the mating direction toward the direction away from the second terminal as it moves toward the second connector side. In a state where the mated portion of the second connector cannot be further mated with the mating portion of the first connector, at least a portion of the guiding inclined portion is arranged at a position corresponding to the common portion of the second terminal when viewed from a direction perpendicular to the surface of the second terminal in contact with the first terminal.
[0009] According to the second method, by providing a guiding inclined portion on the first terminal, when the first connector having the first terminal is mated with the second connector, the guiding inclined portion can be said to be a guide, so that the contact portion of the first terminal can be stably contacted with the second terminal. Since the guiding inclined portion is inclined in a direction away from the second terminal as it moves toward the second connector side in the mating direction from the contact portion of the first terminal, the guiding inclined portion does not contact the second terminal when the contact portion of the first terminal contacts the second terminal. In other words, when the mated portion of the second connector cannot further engage with the mating portion of the first connector, when the surface of the second terminal in contact with the first terminal is observed in a perpendicular direction, the portion of the second terminal that overlaps with at least a portion of the guiding inclined portion of the first terminal becomes a dead space where the first terminal does not contact. That is, since the common portion is arranged in the dead space, the space can be effectively utilized and the impedance can be increased.
[0010] The connector of the third embodiment of the present invention is a connector, in which, in the above-mentioned first embodiment or second embodiment, an inclined portion is provided between the wide portion and the ordinary portion in the second terminal, and the inclined portion smoothly connects the wide portion and the ordinary portion when viewed from a direction perpendicular to the surface of the second terminal in contact with the first terminal.
[0011] According to the third embodiment, an inclined portion is provided between the wide portion and the common portion in the second terminal, and the inclined portion smoothly connects the wide portion and the common portion when viewed from a direction perpendicular to the surface of the second terminal in contact with the first terminal. Therefore, reflection of the electrical signal can be suppressed at the boundary between the wide portion and the common portion.
[0012] The fourth mode of the present disclosure is a connector, in which in any mode from the first mode to the third mode, the common portion of the second terminal is formed to have a substantially constant dimension in the in-plane direction of the surface of the second terminal in contact with the first terminal and in a direction orthogonal to the mating direction of the mated portion.
[0013] According to the fourth aspect, since the dimension of the wide portion in the width direction is formed to be substantially constant, it is possible to suppress reflection of electric signals compared to a structure in which a cutout or the like is partially provided in order to increase impedance.
[0014] A fifth aspect of the present disclosure is a connector, wherein in any one of the first to fifth aspects, the second terminal is formed of a plate material, and a thickness direction of the plate material is a surface perpendicular to a surface of the second terminal in contact with the first terminal.
[0015] According to the fifth embodiment, since the second terminal is formed of a plate material, the thickness direction of the plate material is the perpendicular direction of the surface of the second terminal in contact with the first terminal, and therefore, the wide portion and the ordinary portion are formed so that the width direction dimensions of the respective plates are different. That is, since the wide portion and the ordinary portion are formed by processing the plate material in the width direction, the dimensional accuracy can be improved compared to the case where the plate material is processed in the thickness direction. Therefore, the shape deviation of the second terminal can be reduced.
[0016] As described above, the connector in the present disclosure can excel in connection reliability with a mating terminal and increase the impedance of the terminal. BRIEF DESCRIPTION OF THE DRAWINGS

In the following description, the fitting direction Z is sometimes referred to as the "up-down direction". The connector 10 is formed into a symmetrical shape in the front-back direction and the left-right direction.
[0034] (First connector)
[0035] The first connector 12 is a so-called movable (floating) connector, and includes a movable housing 18 that is fitted with the second connector 14 as a connection object, and a fixed housing 20 that is fixed to a circuit board (not shown). The fixed housing 20 has a pair of side wall portions 22 and 24 that are arranged on both sides of the terminal arrangement direction (arrow Y direction) that is orthogonal to the fitting direction (arrow Z direction) of the second connector 14 with respect to the movable housing 18.
[0036] In addition, the first connector 12 includes a plurality of first terminals 26, which are arranged between the movable housing 18 and the pair of side wall portions 22 and 24 along the installation direction (arrow X direction) and arranged in the fitting direction Z and the terminal arrangement direction Y (refer to Figure 4 ).
[0037] like Figure 4 As shown, the movable housing 18 is formed into a bottomed substantially rectangular tube (substantially cuboid) having a fitting portion 30 opened upward. The movable housing 18 is made of an insulating material such as synthetic resin. In addition, the movable housing 18 in this embodiment is formed into an elongated shape with the left-right direction as the long side, but the left-right dimension of the movable housing 18 is configured to be appropriately changed according to the number of the first terminals 26.
[0038] A plurality of first terminal insertion holes 34 extending in the vertical direction are formed in parallel at equal intervals in the left-right direction on the bottom wall 32 constituting a part of the fitting portion 30. The first terminal insertion holes 34 are open in the vertical direction. In addition, the lower ends of the first terminal insertion holes 34 are opposite to the opposed convex portions 36 ( Figure 4 The opposing surface 38 (only one side is shown in the figure) that is opposite to the circuit substrate is provided on the upper side.
[0039] A fixed housing 20 is provided around the movable housing 18, and the fixed housing 20 has a rectangular through hole 42 that penetrates in the up-down direction and is formed in a substantially rectangular frame shape. The fixed housing 20 is made of an insulating material such as a synthetic resin. In addition, the fixed housing 20 in the present embodiment is formed into an elongated shape with the left-right direction as the long side, but the size of the fixed housing 20 in the left-right direction is configured to be appropriately changed according to the number of the first terminals 26. In addition, a pair of side wall portions 44 and 46 in the front-back direction of the fixed housing 20 are respectively installed with a shielding shell 48 made of metal.
[0040] The movable housing 18 is disposed inside the through hole 42 of the fixed housing 20. Between the inner peripheral surface of the through hole 42 of the fixed housing 20 and the outer peripheral surface of the movable housing 18, a gap 50 having a substantially rectangular ring shape is formed when viewed from the top and bottom.
[0041] A pair of left and right positioning protrusions 40 protruding downward are formed on the fixed housing 20. Each positioning protrusion 40 is fitted into a positioning hole (not shown) formed on the circuit board.
[0042] (First terminal)
[0043] The plurality of first terminals 26 are manufactured by stamping a conductive metal plate into a predetermined shape, and constitute a pair of front and rear terminal rows 52, 54. The front and rear terminal rows 52, 54 are respectively configured to have a plurality of first terminals 26 arranged at equal intervals in the left-right direction. The plurality of first terminals 26 of the front terminal row 52 and the plurality of first terminals 26 of the rear terminal row 54 are formed into the same shape, and are arranged in a posture facing each other in the front-to-back direction. The plurality of first terminals 26 of the front terminal row 52 are arranged between the side wall portion 44 of the front side of the fixed housing 20 and the movable housing 18 along the front-to-back direction, and the plurality of first terminals 26 of the rear terminal row 54 are arranged between the side wall portion 46 of the rear side of the fixed housing 20 and the movable housing 18 along the front-to-back direction.
[0044] Each first terminal 26 includes: a first contact portion 60, which is held by the movable housing 18, elastically deformed toward the outside in the front-rear direction, and electrically contacted with a second terminal 64 described later and provided on the second connector 14; a first elastic portion 62, which extends from the first contact portion 60 toward the outside in the front-rear direction and is capable of elastic deformation; and a first connecting portion 66, which extends from the end of the first elastic portion 62 on the side opposite to the first contact portion 60 toward the outside in the front-rear direction and is held by the fixed housing 20, and is fixed to the circuit substrate.
[0045] The first contact portion 60 is formed in a long and narrow plate shape with the left-right direction as the plate thickness direction and the up-down direction as the longitudinal direction, and is inserted into the first terminal insertion hole 34 of the movable housing 18 from the lower side. The substantially lower half of the first contact portion 60 serves as a first retaining portion 68 inserted (pressed) into the first terminal insertion hole 34 of the movable housing 18. The first retaining portion 68 is provided with a plurality of claws 70 protruding toward the center side in the front-back direction of the movable housing 18 in a vertically aligned manner. The first retaining portion 68 is retained by the movable housing 18 by the plurality of claws 70 biting into the inner peripheral surface of the first terminal insertion hole 34.
[0046] The upper half of the first contact portion 60 is formed as a first terminal elastic portion 72 extending in the vertical direction. The first terminal elastic portion 72 is arranged in the fitting portion 30 of the movable housing 18 and can be elastically deformed in the front-to-back direction. A first terminal contact portion 74 (see FIG. 1 ) is formed on the upper end side of the first terminal elastic portion 72 and protrudes into the fitting portion 30 of the movable housing 18. Fig. 9 ). The first terminal contact portion 74 contacts the second terminal 64 provided on the second connector 14. Thus, the first terminal 26 and the second terminal 64 are electrically connected.
[0047] A guide inclined portion 76 is provided on the upper side of the first terminal contact portion 74 in the first terminal elastic portion 72. The guide inclined portion 76 has an inclined surface that is inclined toward the front-rear direction outer side as it goes upward from the first terminal contact 74. In other words, it is inclined in a manner that it is away from the second terminal 64 as it goes toward the front end side in the first terminal elastic portion 72 from the first terminal contact portion 74.
[0048] The first connecting portion 66 includes: a first press-in portion 80, which is inserted (pressed) into a first terminal insertion hole 82 formed in the fixed housing 20 from the lower side; a first connecting piece 86, which extends outward in the front and rear directions from the lower end of the first press-in portion 80 and is inserted into a groove portion 84 of the first terminal insertion hole 82 (see Figure 2 ), the first connection portion 66 is formed in a substantially L-shape when viewed from the left and right directions. A claw portion 70 is formed on the upper portion of the first press-in portion 80, which protrudes toward the center side in the front-to-back direction of the fixed housing 20. The first press-in portion 80 is held in the fixed housing 20 by the claw portion 70 hooking on the inner peripheral surface of the first terminal insertion hole 82. The first connection piece 86 protrudes further outward in the front-to-back direction than the fixed housing 20. The first connection piece 86 is fixed (electrically connected) to the circuit substrate by welding or other methods.
[0049] The first elastic portion 62 constitutes the middle portion of the first terminal 26 in the front-to-back direction, and extends integrally from the lower end of the first contact portion 60 toward the outer side in the front-to-back direction. The first connecting portion 66 extends integrally from the end of the first elastic portion 62 on the side opposite to the first contact portion 60. The first elastic portion 62 has a first spring portion 88 that is convex and bent upward (in the direction of removal of the second connector 14) as the middle portion in the front-to-back direction. The first spring portion 88 is in an inverted U-shape with the lower side open when viewed from the left-right direction.
[0050] (Second connector)
[0051] The second connector 14 is provided with a second housing 90 and a plurality of second terminals 64. The second housing 90 is formed into a substantially rectangular cylindrical shape (substantially a rectangular parallelepiped shape). The second housing 90 is made of an insulating material such as a synthetic resin. In addition, the second housing 90 in the present embodiment is formed into an elongated shape with the left-right direction as the long side, but the left-right dimension of the second housing 90 is configured to be appropriately changed according to the number of the second terminals 64.
[0052] The second housing 90 has an engaged portion 92 at the bottom thereof. The engaged portion 92 is disposed approximately at the center of the bottom surface 94 of the second housing 90 in the front-rear direction and the left-right direction, and protrudes downward from the bottom surface 94. Figure 1 As shown, the engaged portion 92 is formed into a substantially rectangular parallelepiped shape with the left-right direction as the long side direction, and a pair of side walls 104 in the front-back direction are formed with a plurality of groove-like portions 96 arranged side by side at equal intervals in the left-right direction. The groove-like portions 96 extend in the up-down direction and have a cross-sectional shape orthogonal to the long side direction and are open toward the outside in the front-back direction (see Figure 6 ), the upper end and the second terminal insertion hole 102 (refer to Figure 4 ), the second terminal insertion hole 102 is connected in the up-down direction from the bottom surface 94 to the bottom wall 100 of the recess 98 provided on the upper side of the second housing 90. In addition, a pair of side wall portions 106 of the recess 98 are formed with a plurality of groove-like portions 108 extending in the up-down direction at equal intervals in the left-right direction at positions corresponding to the second terminal insertion hole 102. In addition, a pair of upper wall portions 110 of the recess 98 are also formed with groove-like portions 112 extending in the front-rear direction at equal intervals in the left-right direction at positions corresponding to the groove-like portions 108.
[0053] A pair of extended wall portions 114 are provided on the left and right outer sides of the fitted portion 92. The extended wall portions 114 extend from the bottom surface 94 (see Figure 4 ) protrudes downward in the left-right direction. The protrusion amount of the extended wall portion 114 relative to the bottom surface 94 is greater than the protrusion amount of the engaged portion 92 relative to the bottom surface 94.
[0054] A pair of shielding shells 120 are provided in the front-rear direction on the side walls 116 and 118 of the second housing 90. The shielding shells 120 are made of a metal plate and are inserted from the bottom into deep grooves 122 (see FIG. 1 ) formed on the side walls 116 and 118 of the second housing 90 and opening downward. Figure 4 ) In addition, the shielding shell 120 is formed symmetrically in the front-rear direction, thereby forming a substantially square tube shape in which the fitted portion 92 and the extended wall portion 114 are accommodated.
[0055] like Figure 2 As shown, a plurality of abutment portions 126 are formed on the outer sides of the side walls 116 and 118 in the front-rear direction relative to the shield shell 120. The abutment portions 126 are configured such that when the second connector 14 is fitted into the first connector 12, the bottom wall portion 128 (see Figure 1 ) are respectively opposed to the upper end portions of the side wall portions 44 and 46 in the fixed housing 20 of the second connector 14.
[0056] In addition, abutment portions 130 are formed on the side walls 116 and 118 on the outer side in the left-right direction relative to the shield shell 120. The abutment portions 130 are configured such that, when the second connector 14 is fitted to the first connector 12, the abutment portions 130 are inserted from above into a pair of fitting grooves 132 formed on the outer side in the left-right direction of the fixed housing 20 and open upward, and the bottom wall portion 134 (see Figure 1 ) is opposite to the bottom wall portion 136 of the fitting groove 132.
[0057] In addition, when the second connector 14 is fitted into the first connector 12, the lower end portion of the shield shell 120 of the first connector 12 and the extended wall portion 114 (see Figure 5 ) is inserted into the gap 50 of the first connector 12, and the engaged portion 92 of the second connector 14 is engaged with the engaging portion 30 of the first connector 12. Figure 4 As shown in FIG. 1 , when the engaged portion 92 of the second connector 14 is engaged with the engaging portion 30 of the first connector 12, the top wall portion 138 (see FIG. 1 ) of the engaged portion 92 is Figure 1 ) is opposite to the bottom wall 32 of the fitting portion 30.
[0058] (Second terminal)
[0059] The plurality of second terminals 64 are manufactured by stamping a conductive metal plate into a predetermined shape, and constitute a pair of front and rear terminal rows 140, 142. The front and rear terminal rows 140, 142 are respectively configured such that the plurality of second terminals 64 are arranged side by side at equal intervals in the left and right directions along the thickness direction of the second terminal 64 along the front and rear directions (see Figure 5The plurality of second terminals 64 of the front terminal array 140 and the plurality of second terminals 64 of the rear terminal array 142 are formed in the same shape, but are arranged in a posture facing each other in the front-to-back direction. The plurality of second terminals 64 of the front terminal array 140 are provided on the side wall portion 104 on the front side of the engaged portion 92 (see Figure 1 ), the plurality of second terminals 64 of the rear terminal row 142 are provided on the side wall portion 104 on the rear side of the engaged portion 92 (see Figure 1 ).
[0060] like Figure 4 As shown, each second terminal 64 is held in the engaged portion 92 and has: an exposed portion 144, located between the engaged portion 92 and the shielding shell 120; a second retaining portion 146, extending upward from the exposed portion 144 and partially inserted into the second terminal insertion hole 102 and the groove portion 108; a second connecting portion 148, extending outward in the front and rear directions from the end of the second retaining portion 146 on the opposite side of the exposed portion 144 and arranged in the groove portion 112 of the second shell 90, and fixed to the circuit substrate.
[0061] like Figure 5 As shown, in the exposed portion 144, a portion of the lower end side of the second terminal 64 is exposed to the outside, and the exposed portion 144 has: a wide portion 150 (see Figure 8 ), electrically contacting the first terminal 26 provided on the first connector 12; a common portion 152, extending upward from the wide portion 150; and an inclined portion 154, provided between the wide portion 150 and the common portion 152.
[0062] The wide portion 150 is provided on the front end side of the engaged portion 92, and Figure 8 As shown, the thickness direction of the second terminal 64 is perpendicular to the first terminal contact portion 74 (see Fig. 9 The width dimension of the contact surface 156 of the surface in contact with the wide portion 150 is set to be larger than the width dimension of the ordinary portion 152. In addition, a guide portion 158 is formed at the front end of the wide portion 150, and the guide portion 158 is formed with an inclined surface whose dimensions in the width direction and the plate thickness direction increase as it goes upward.
[0063] Tapered portions 160 are formed at a pair of end portions in the left-right direction of the contact surface 156 of the wide portion 150. Figure 6 As shown, the tapered portion 160 is formed to face the chamfered portion 162 in the cross-sectional shape of the groove-shaped portion 96 .
[0064] like Fig.10As shown, the wide portion 150 is configured such that the first terminal contact portion 74 of the first terminal 26 contacts the contact surface 156 of the wide portion 150 when the second connector 14 cannot be further fitted (inserted) into the first connector 12. Figure 2 In the normal mating state of the first connector 12 and the second connector 14 shown in FIG. Fig. 9 As shown in FIG. 1 , the first terminal contact portion 74 of the first terminal 26 contacts the wide portion 150 of the second terminal 64. In this state, if the second connector 14 is further fitted into the first connector 12, as shown in FIG. Figure 3 As shown, the bottom wall portion 134 (see Figure 1 ) abuts against the bottom wall portion 136 of the fitting groove 132 of the first connector 12. Similarly, the bottom wall portion 128 (see Figure 1 ) abuts against the upper ends of the side walls 44 and 46 of the second connector 14. As a result, the second connector 14 is no longer able to be further engaged with the first connector 12. In this state, Fig.10 As shown, the second terminal 64 moves downward, but the vertical range of the wide portion 150 is set so that the first terminal contact portion 74 of the first terminal 26 does not contact the inclined portion 154 and the normal portion 152 of the second terminal 64 .
[0065] like Figure 7 As shown, the normal portion 152 is set to have a smaller width dimension than the wide portion 150 and the width dimension is substantially constant. Figure 8 As shown in the figure, the inclined portion 154 is provided with a pair of left and right inclined surfaces 168, and the inclined surfaces 168 are connected to the side wall portion 153 of the general portion 152 from the upper end of the side wall portion 151 of the wide portion 150 while heading upward. As an example, the inclination angle of the inclined surface 168 relative to the up-down direction is set to an acute angle so as to smoothly connect the wide portion 150 and the general portion 152.
[0066] (Effect)
[0067] Next, the effects of this embodiment will be described.
[0068] In the present embodiment, the wide portion 150 is formed in the second terminal 64 provided in the fitted portion 92 of the second connector 14. The wide portion 150 is provided on the front end side of the fitted portion 92 of the second connector 14 in the second terminal 64, and the width direction dimension of the wide portion 150 is set to be larger than the width direction dimension of the general portion 152. In addition, from the state where the fitted portion 92 of the second connector 14 begins to be fitted in the fitting portion 30 of the first connector 12 to the state where the fitted portion 92 cannot be further fitted (refer to Figure 3 ) Fig.10As shown, the first terminal 26 contacts the wide portion 150 of the second terminal 64. Therefore, since the first terminal 26 does not contact the common portion 152 of the second terminal 64, the contact area with the first terminal 26 does not need to be considered with respect to the width direction dimension of the common portion 152. Therefore, in order to increase the impedance, the width direction dimension of the common portion 152 can be reduced.
[0069] Furthermore, when the engaged portion 92 of the second connector 14 cannot be further engaged in the engaging portion 30 of the first connector 12, the first terminal 26 is in contact with the wide portion 150 of the second terminal 64, which is larger in width than the ordinary portion 152, so that the contact area is easily ensured. In other words, the electrical conduction state can be ensured. As a result, the impedance of the terminal can be increased while the connection reliability with the mating terminal is excellent.
[0070] In addition, if Fig. 9 As shown in the figure, by providing the guide inclined portion 76 on the first terminal 26, when the first connector 12 having the first terminal 26 is mated with the second connector 14, the guide inclined portion 76 can be said to be a guide and can stably contact the second terminal 64. Since the guide inclined portion 76 is inclined in a direction away from the second terminal 64 along the mating direction Z from the first terminal contact portion 74 toward the second connector 14 side, the guide inclined portion 76 does not contact the second terminal 64 when the first terminal contact portion 74 contacts the second terminal 64. In other words, when the mated portion 92 of the second connector 14 cannot be further mated into the mating portion 30 of the first connector 12, when viewed from a direction perpendicular to the surface of the contact surface 156 of the second terminal 64 that contacts the first terminal 26, the portion of the second terminal 64 that at least partially overlaps with the guide inclined portion 76 of the first terminal 26 becomes a dead zone where the first terminal 26 does not contact. That is, since the common portion 152 is arranged in this dead zone, the space can be effectively used and the impedance can be increased.
[0071] In addition, an inclined portion 154 is provided between the wide portion 150 and the normal portion 152 in the second terminal 64, and the inclined portion 154 smoothly connects the wide portion 150 and the normal portion 152 when viewed from a direction perpendicular to a contact surface 156 in the second terminal 64 that contacts the first terminal 26. Therefore, reflection of the electrical signal can be suppressed at the boundary between the wide portion 150 and the normal portion 152.
[0072] Furthermore, since the width dimension of the common portion 152 is formed to be substantially constant, reflection of electric signals can be suppressed compared to a structure in which a cutout or the like is partially provided in order to increase impedance.
[0073] In addition, since the second terminal 64 is formed of a plate material whose surface perpendicular to the contact surface 156 in contact with the first terminal 26 is in the thickness direction, the wide portion 150 and the ordinary portion 152 are formed so that the width direction dimensions of the respective plates are different. In other words, since the wide portion 150 and the ordinary portion 152 are formed by processing the plate material in the width direction, the dimensional accuracy can be improved compared to the case where the plate material is processed in the thickness direction. Therefore, the shape deviation of the second terminal 64 can be reduced.
[0074] (Variation Example)
[0075] In addition, if Figure 8 As shown in FIG. 1 , although the tapered portion 160 is provided at a pair of end portions in the left-right direction of the contact surface 156 of the second terminal 64, the present invention is not limited thereto. Fig.11 As shown in FIG. 1 , the tapered portion 160 may not be provided at a pair of end portions in the left-right direction of the contact surface 182 of the second terminal 180. Fig.12 As shown, since the corners 184 of a pair of ends in the left-right direction of the contact surface 182 of the second terminal 180 interfere with the chamfered portion 162 of the groove-shaped portion 96, the second terminal 180 applies a force to the inside in the front-rear direction, so that the second terminal 180 can be properly arranged in the groove-shaped portion 96 during assembly. Therefore, when the first connector 12 is mated, the first terminal 26 and the second terminal 180 can be stably contacted.
[0076] As mentioned above, although embodiment of this disclosure was described, this disclosure is not limited to the above, and it is a matter of course that various deformation|transformation other than the above-mentioned can be performed within the range which does not deviate from the summary.
