Description

[Technical Field]

[0001] The present disclosure relates to connectors. [Background technology]

[0002] The connector of Patent Document 1 includes terminals and a housing. The terminals have portions (exposed portions) that are exposed from the housing. Since the impedance of the exposed portions is likely to increase, the exposed portions are formed to be wide to achieve impedance matching. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-35352 [Patent Document 2] Patent Publication No. 2021-26874 Summary of the Invention [Problem to be solved by the invention]

[0004] However, if the width of the exposed portions (the dimension in the direction in which the multiple exposed portions are arranged) is made too large, the distance between adjacent exposed portions becomes narrow, which may cause short-circuiting between the terminals. Therefore, there is a limit to how much the impedance of the exposed portions can be reduced by increasing the width of the exposed portions.

[0005] The problem to be solved by the present disclosure is to reduce the impedance of the exposed portion while preventing short circuits between terminals. [Means for solving the problem]

[0006] The connector of the first aspect is a connector comprising a plurality of terminals and a housing, wherein the terminals have exposed portions exposed from the housing, the exposed portions have impedance adjustment portions, the impedance adjustment portions extend in the same direction as the impedance adjustment portions of other terminals at positions adjacent to each other, and the impedance adjustment portions have a convex portion protruding in a direction toward the adjacent impedance adjustment portion, and a concave portion provided at a position corresponding to the convex portion of the adjacent impedance adjustment portion and recessed in a direction away from the adjacent impedance adjustment portion.

[0007] In this aspect, the connector includes a plurality of terminals and a housing. Each of the plurality of terminals has an exposed portion. The exposed portion has an impedance adjustment portion. The impedance adjustment portion extends in the same direction as the impedance adjustment portions of the other terminals and at a position adjacent to the impedance adjustment portions of the other terminals.

[0008] Here, the impedance adjustment section has a convex section that protrudes in a direction toward the adjacent impedance adjustment section, and a concave section that is recessed in a direction away from the adjacent impedance adjustment section. Therefore, compared to a configuration in which the opposing surfaces of adjacent impedance adjustment units extend parallel to the extension direction, the surface area of ​​the opposing surfaces of adjacent impedance adjustment units increases, and the impedance of the impedance adjustment units decreases. As a supplementary note, when inductance is L and capacitance is C, in the high frequency range, impedance is a value close to √L / C. This C is proportional to the surface area of ​​the two conductors lined up side by side. In other words, if the surface area of ​​the two conductors lined up can be increased, the impedance will decrease.

[0009] Furthermore, the recesses of the impedance adjustment portions are provided at positions corresponding to the protrusions of the adjacent impedance adjustment portions. Therefore, compared to an embodiment in which the convex portion of the impedance adjustment portion is provided at a position corresponding to the convex portion of an adjacent impedance adjustment portion, there are fewer locations where the gap between adjacent impedance adjustment portions is small, and as a result, short-circuiting between terminals is prevented.

[0010] As described above, according to this aspect, it is possible to reduce the impedance of the exposed portion while preventing short circuits between terminals.

[0011] In the embodiment described below, an example will be described in which the "plurality of terminals" refers to all of the terminals provided in the connector. However, the "plurality of terminals" in this embodiment is not limited to this. The "plurality of terminals" in this embodiment may be two or three of the many terminals provided in the connector. In other words, the connector in this embodiment may be provided with terminals other than the "plurality of terminals" in this embodiment. In the embodiment described below, an example will be described in which the impedance adjustment portion extends linearly, but the impedance adjustment portion of this embodiment is not limited to this. In the embodiment described below, an example will be described in which the thickness direction of the impedance adjustment portion is perpendicular to both the arrangement direction and the extension direction. However, the impedance adjustment portion of this embodiment is not limited to this, and may be one in which the thickness direction is not assumed (for example, a terminal is not made of a plate material). In the embodiment described below, an example in which the exposed portion is exposed to air will be described. However, the exposed portion of this embodiment is not limited to this and may be disposed in, for example, a gel or liquid substance.

[0012] The connector according to a second aspect is the connector of the first aspect, wherein the convex portion and the concave portion are formed by cut surfaces.

[0013] In this embodiment, the protrusions and recesses are formed by the cut surfaces. Therefore, the projections and recesses can be easily formed.

[0014] One possible method for manufacturing a connector of this type is to form multiple terminals together by punching and bending, and then hold the formed multiple terminals in a housing while they are connected by a carrier. In this method, if there are any locations where the gap between the terminals is small, a problem arises in the strength of the press die used to form the gap. However, in this aspect, as described above, the gap between adjacent impedance adjustment portions is unlikely to be small, and therefore the above problem is unlikely to occur. Therefore, the connector of this aspect is suitable for the above-mentioned manufacturing method. Patent Document 2 discloses a technique in which multiple terminals connected to a carrier are held in a housing in two separate steps (paragraph 0187). However, this technique requires multiple assembly steps, resulting in poor productivity.

[0015] A connector according to a third aspect is the connector of the first or second aspect, which is attached to an object to be attached and used, the housing has a fixed housing fixed to the object to be attached, the terminal has a connection portion connected to the object to be attached and a fixed side held portion held by the fixed housing, and the impedance adjustment portion is formed between the connection portion and the fixed side held portion.

[0016] When a terminal has a connection portion and a fixed-side held portion, and there is an exposed portion between them, the exposed portion tends to have a higher impedance than the connection portion and the fixed-side held portion. Therefore, in this aspect, the impedance adjusting portion is formed between the connecting portion and the fixed-side held portion. Therefore, it is possible to match the impedance between the connection portion, the fixed-side held portion, and the exposed portion therebetween.

[0017] A connector according to a fourth aspect is the connector of the first or second aspect, which is attached to an object to be attached and used, the housing has a fixed housing fixed to the object to be attached and a movable housing movable relative to the fixed housing, the terminals have a fixed side held portion held by the fixed housing and a movable side held portion held by the movable housing, and the impedance adjustment portion is formed between the fixed side held portion and the movable side held portion.

[0018] When a terminal has a fixed-side held portion and a movable-side held portion with an exposed portion between them, the exposed portion tends to have higher impedance than the fixed-side held portion and the movable-side held portion. Therefore, in this aspect, the impedance adjusting portion is formed between the fixed-side held portion and the movable-side held portion. Therefore, it is possible to match the impedance between the fixed-side held portion, the movable-side held portion, and the exposed portion therebetween.

[0019] The connector of the fifth aspect is any one of the first to fourth aspects, wherein the average width dimension of the impedance adjustment portion is larger than the width dimension of the portion connected to one end of the impedance adjustment portion and larger than the width dimension of the portion connected to the other end of the impedance adjustment portion.

[0020] The width dimension means the dimension in the direction in which the impedance adjustment portions are adjacent.

[0021] In this aspect, the average width of the impedance adjustment portion is larger than the width of the portion connected to one end of the impedance adjustment portion, and is larger than the width of the portion connected to the other end of the impedance adjustment portion. This allows the impedance of the impedance adjusting section to be further reduced.

[0022] The connector of the sixth aspect is any one of the first to fifth aspects, wherein the convex portion has an arc-shaped edge that is convex in a direction toward the adjacent impedance adjustment portion, and the concave portion has an arc-shaped edge that is convex in a direction away from the adjacent impedance adjustment portion.

[0023] In the present disclosure, the term "arc-shaped" includes not only a strict arc-shaped shape but also a shape close to an arc-shaped shape (for example, a sinusoidal curve shape).

[0024] In this aspect, the convex portion has an arc-shaped edge that is convex in a direction toward the adjacent impedance adjustment portion, and the concave portion has an arc-shaped edge that is convex in a direction away from the adjacent impedance adjustment portion. Therefore, when the protrusions and recesses are formed by cutting surfaces, the protrusions and recesses are easily formed. In other cases, the protrusions and recesses are also easily formed.

[0025] A connector according to a seventh aspect is the connector of any one of the first to sixth aspects, wherein the convex portion and the concave portion are formed continuously.

[0026] In this embodiment, the convex portions and the concave portions are formed continuously, i.e., there is no part extending linearly in the extension direction between the convex portions and the concave portions. Therefore, the protrusions and recesses are efficiently arranged, and the number of protrusions and recesses can be increased to efficiently increase the surface area.

[0028] Hereinafter, a first connector 100 and a second connector 200, which are embodiments of connectors according to the present disclosure, will be described.

[0029] The arrow X shown in each figure may be referred to as the front-to-back direction of the connector, the arrow Y as the width direction of the connector, and the arrow Z as the up-to-down direction of the connector.

[0030] (Connector set 100, 200) 1 to 3 show a connector set 100, 200 consisting of a first connector 100 and a second connector 200. FIG. The first substrate B1 and the second substrate B2 can be connected by attaching the first connector 100 to the first substrate B1, attaching the second connector 200 to the second substrate B2, and connecting the first connector 100 and the second connector 200. The first substrate B1 and the second substrate B2 are arranged parallel to each other. The first connector 100 is a floating connector, and the second connector 200 is not a floating connector.

[0031] (first connector 100) The first connector 100 includes first housings 10, 20 and a plurality of first terminals 30. The first housings 10, 20 include a fixed housing 10 and a movable housing 20.

[0032] The fixed housing 10 is a housing that is fixed to the first board B1, which is an object to which the first connector 100 is attached. The fixed housing 10 is fixed to the first board B1 via a plurality of first terminals 30.

[0033] The movable housing 20 is a housing that is provided so as to be movable relative to the fixed housing 10. The movable housing 20 is supported by a plurality of first terminals 30 in a floating state.

[0034] The fixed housing 10 and the movable housing 20 are made of an insulating material such as synthetic resin.

[0035] The first terminal 30 connects the first substrate B1 and the second terminal 50 of the second connector 200. The first terminal 30 is made by subjecting a conductive plate material to punching, bending, and other processes. The first terminals 30 each have the same shape.

[0036] The plurality of terminals 30 are composed of a plurality of terminals 30 (four in the figure) on the front side and a plurality of terminals 30 (four in the figure) on the rear side. The front terminals 30 and the rear terminals 30 form a pair of terminals 30 (see FIG. 4), and the pair of terminals 30 can also be understood as being arranged in the Y direction. The pair of terminals 30 are arranged opposite each other so that their contact portion side directions (the direction in which the contact portion 35b is located relative to the connection portion 31 when viewed from the Z direction) face inward in the X direction.

[0037] Next, the first terminal 30 will be described in detail.

[0038] As shown in FIG. 4, the first terminal 30 has a connecting portion 31, a fixed-side held portion 32, a middle portion 33, a movable-side held portion 34, and a tip portion 35 in this order.

[0039] The connection portion 31 is a portion that is connected to the first substrate B1, which is the attachment object. The connection portion 31 extends outward in the X direction, which is a direction along the surface of the first substrate B1, from the fixed-side held portion 32. The connection portion 31 is soldered to the surface of the first substrate B1.

[0040] The fixed-side held portion 32 is a portion that is held by the fixed housing 10 . The fixed-side held portion 32 is held in the fixed housing 10 by being press-fitted into the fixed housing 10 with the +Z direction as the press-fit direction. The fixed-side held portion 32 extends in the +Z direction with its plate width direction facing the Y direction, which is the terminal arrangement direction. The fixed-side held portion 32 has press-fit protrusions. The press-fit protrusions are formed on both sides of the fixed-side held portion 32 in the plate width direction.

[0041] The intermediate portion 33 is a portion that connects the fixed-side held portion 32 and the movable-side held portion 34, and is formed to be deformable so that the movable-side held portion 34 can be displaced relative to the fixed-side held portion 32. The intermediate portion 33 is a portion that is not held by either housing, and is exposed from the first housings 10, 20. Hereinafter, the intermediate portion 33 may be referred to as the exposed portion 33. The intermediate portion 33 has, in this order, a curved portion 33a on one end side, a straight portion 33b, and a curved portion 33c on the other end side.

[0042] The one-end curved portion 33a converts the Z-direction component of the extending direction of the first terminal 30 from positive to negative.

[0043] The straight portion 33b is a portion whose extension direction is linear. The extension direction of the straight portion 33b is the -Z direction and a diagonal direction inward in the X direction. The plate width direction of the straight portion 33b faces the Y direction, which is the terminal arrangement direction. The straight portion 33b does not have a portion bent in the plate thickness direction. An impedance adjustment portion 60 is formed in the straight portion 33b. The impedance adjustment portion 60 will be described later.

[0044] The other end curved portion 33c converts the Z direction component of the extending direction of the first terminal 30 from negative to positive.

[0045] The movable-side held portion 34 is a portion that is held by the movable housing 20 . The movable-side held portion 34 is held by the movable housing 20 by being press-fitted into the movable housing 20 with the +Z direction as the press-fit direction. The movable-side held portion 34 extends in the +Z direction, with its plate width direction facing the Y direction, which is the terminal arrangement direction. The movable-side held portion 34 has press-fit protrusions. The press-fit protrusions are formed on both sides of the movable-side held portion 34 in the plate width direction.

[0046] The tip portion 35 is a portion located on the one end side of the movable held portion 34 . The tip portion 35 has a contact portion 35b and an elastic support portion 35a.

[0047] The contact portion 35b is a portion that comes into contact with a mating terminal (not shown) of a mating connector (not shown). The contact portion 35b is bent in the thickness direction so as to be convex inward in the X direction, which is the direction in which the contact portion 35b comes into contact with the second terminal 50.

[0048] The elastic support portions 35a are portions that elastically support the contact portions 35b. When a mating connector (not shown) is connected to the connector 100, the elastic support portions 35a are elastically deformed so that the contact portions 35b are displaced outward in the X direction.

[0049] The width direction of the first terminal 30 faces the Y direction regardless of the location. The extension direction of the first terminal 30 is a direction in a plane perpendicular to the Y direction regardless of the location. The width direction means a direction perpendicular to both the extension direction and the thickness direction.

[0050] (Fixed housing 10) Next, the stationary housing 10 will be described in detail.

[0051] 6, the fixed housing 10 includes a front terminal holding portion 11 and a rear terminal holding portion 11. The front terminal holding portion 11 and the rear terminal holding portion 11 have the same structure. Hereinafter, when there is no need to distinguish between the two, they will simply be referred to as the terminal holding portion 11.

[0052] The terminal holding portion 11 has a plurality of arrangement direction walls 12 . The arrangement direction walls 12 are located on both sides of the fixed-side held portion 32 of the terminal 30 in the arrangement direction and the Y direction, which is the plate width direction. The fixed-side held portion 32 is press-fitted into the space between adjacent arrangement direction walls 12 among the multiple arrangement direction walls 12. This space is open on the inside in the X direction. This allows the middle portion 33 of the terminal 30 (specifically, the one-end curved portion 33a) to pass through the open portion when the fixed-side held portion 32 is press-fitted.

[0053] The terminal holder 11 has an outer wall 13 . The outer wall 13 is located outward in the X direction from the fixed-side held portion 32. The outer wall 13 is connected to outer ends of the multiple arrangement direction walls 12 in the X direction.

[0054] The terminal holder 11 has a top wall 14 . The top wall 14 is located in the +Z direction relative to the fixed-side held portion 32 and part of the intermediate portion 33. The top wall 14 is connected to the +Z direction sides of the multiple arrangement direction walls 12. The top wall 14 extends inward in the X direction from the +Z direction end of the outer wall 13.

[0055] (movable housing 20) Next, the movable housing 20 will be described in detail.

[0056] As shown in FIG. 7, the movable housing 20 has a plurality of arrangement direction walls 21. The arrangement direction walls 21 are located on both sides in the Y direction, which is the arrangement direction, of some of the terminals 30. The arrangement direction walls 21 have guide surfaces 21b2 that guide the second connector 200, which is the mating connector, to an appropriate position in the X direction.

[0057] The arrangement direction wall 21 has a lower arrangement direction wall 21a and an upper arrangement direction wall 21b. The lower arrangement direction wall 21a corresponds to the movable-side held portion . The upper arrangement direction wall 21b corresponds to the tip portion 35. The upper arrangement direction wall 21b is divided into a front portion and a rear portion. A space into which a part of the second connector 200, which is a mating connector, is inserted is formed between the front upper arrangement direction wall 21b and the rear upper arrangement direction wall 21b. The lower arrangement direction wall 21a has a front portion and a rear portion that are integrally formed.

[0058] The movable housing 20 has a pair of outer walls 22, one at the front and one at the rear. The outer wall 22 is located outward in the X direction from a portion of the terminals 30. The outer wall 22 connects the multiple arrangement direction walls 21 at their outer portions in the X direction. The outer wall 22 has a guide surface 22b1 that guides the second connector 200, which is the mating connector, to an appropriate position in the X direction.

[0059] The outer wall 22 has a lower outer wall 22a and an upper outer wall 22b. The lower outer wall 22a corresponds to the movable-side held portion . The upper outer wall 22b corresponds to the tip portion 35.

[0060] The movable housing 20 has an arrangement direction connecting wall 23 . The arrangement direction connecting wall 23 connects the plurality of lower arrangement direction walls 21a in the arrangement direction. The space between the arrangement direction connecting wall 23 and the lower outer wall 22a is a space through which the tip end 35 of the terminal 30 passes when the terminal 30 is assembled to the movable housing 20, and through which the movable-side held portion 34 is disposed. The movable-side held portion 34 is press-fitted between adjacent lower arrangement direction walls 21a.

[0061] The movable housing 20 has a top wall 24. The top wall 24 extends inward in the X direction from the upper end of the outer wall 22.

[0062] (Second connector 200) 1, the second connector 200 includes a second housing 40 and a plurality of second terminals 50. The second housing 40 includes only a fixed housing and does not include a movable housing.

[0063] The second housing 40 is fixed to a second board B2, which is an object to which the second connector 200 is attached. The second housing 40 is fixed to the second board B2 via a plurality of second terminals 50. The second housing 40 is formed of an insulating material such as synthetic resin.

[0064] The second terminal 50 connects the second substrate B2 and the first terminal 30 of the first connector 100. The second terminal 50 is made by subjecting a conductive plate material to punching, bending, and other processes. The second terminals 50 each have the same shape.

[0065] The plurality of second terminals 50 includes a plurality of second terminals 50 (four in the figure) on the front side and a plurality of second terminals 50 (four in the figure) on the rear side. The front second terminal 50 and the rear second terminal 50 form a pair of second terminals 50 (see FIG. 8), and the pair of second terminals 50 can also be understood as being arranged with the Y direction as the terminal arrangement direction. The pair of second terminals 50 are arranged opposite each other with their contact portion sides facing inward in the X direction.

[0066] (Second terminal 50) Next, the second terminal 50 will be described in detail.

[0067] The second terminal 50 has a connecting portion 51, a held portion 53, and a tip portion 54 in this order.

[0068] The connection portion 31 is a portion that is connected to the second substrate B2. The connection portion 31 extends outward in the X direction, which is a direction along the surface of the second substrate B2, and is soldered to the surface of the second substrate B2.

[0069] The held portion 53 is a portion that is held by the second housing 40 . The held portion 53 is press-fitted into the second housing 40 with the -Z direction as the press-fit direction, and is thereby held in the second housing 40. The held portion 53 has press-fit protrusions 53a. The press-fit protrusions 53a are formed on both sides of the held portion 53 in the plate width direction.

[0070] The tip portion 54 is a portion on the other end side of the held portion 53 . The tip portion 54 is connected to the held portion 53 without any curved portion therebetween and extends linearly in the −Z direction, so that the held portion 53 and the tip portion 54 extend linearly in the −Z direction. The tip portion 54 has a connecting portion 54a and a contact portion 54b.

[0071] The connecting portion 54a is a portion that connects the held portion 53 and the contact portion 54b. The contact portion 54b is a portion that comes into contact with the first terminal 30 of the first connector 100. The surface of the contact portion 54b that comes into contact with the first terminal 30 is the surface on the outer side in the X direction.

[0072] The second terminal 50 has a relay portion 52 between the connecting portion 51 and the held portion 53 . The relay portion 52 connects the connecting portion 51 and the held portion 53 in the X direction. The relay portion 52 has, from the connecting portion 51 side, a one-end curved portion 52a, a straight portion 52b, and an other-end curved portion 52c.

[0073] The one-end curved portion 52a connects the connecting portion 51 and the straight portion 52b. The bending angle of the one-end curved portion 52a is 45 degrees or less. The linear portion 52b extends linearly inward in the X direction. The other end curved portion 52c connects the straight portion 52b and the held portion 53 together.

[0074] The one-end curved portion 52a is press-fitted into and held in the fixed housing 10. Hereinafter, this portion may be referred to as the additional held portion 52a. As a result, the straight portion 52b and the other-end curved portion 52c, which are portions of the relay portion 52 closer to the fixed-side held portion 32 than the additional held portion 52a, are exposed from the second housing 40. Hereinafter, the straight portion 52b and the other-end curved portion 52c may be referred to as the exposed portions 52b, 52c.

[0075] The straight portion 52b is formed with an impedance adjusting portion 60. The impedance adjusting portion 60 will be described later.

[0076] (Second housing 40) The second housing 40 has a base 41 .

[0077] A terminal press-fit hole 42 is formed in the base 41. The terminal press-fit hole 42 is a hole that penetrates the base 41 in the Z direction, and is a hole into which the held portion 53 of the second terminal 50 is press-fitted and held.

[0078] The second housing 40 has a terminal arrangement wall 43 .

[0079] A terminal placement groove 44 is formed in the terminal placement wall 43. The terminal placement groove 44 is a groove that linearly continues from the terminal press-fit hole 42, and is a groove in which the tip portion 54 of the second terminal 50 is placed.

[0080] An adjustment groove 45 is formed inside the terminal press-fit hole 42 and the terminal arrangement groove 44, extending along the terminal press-fit hole 42 and the terminal arrangement groove 44. The adjustment groove 45 is formed to adjust the impedance of the second terminal 50. The adjustment groove 45 is a groove whose depth direction is inward in the X direction.

[0081] The second housing 40 has a plurality of arrangement direction walls 46 located on both sides in the Y direction of the one-end curved portion 52a (additional held portion 52a) of the second terminal 50. The additional held portion 52a is press-fitted between adjacent arrangement direction walls 46 with the -Z direction as the press-fit direction. The arrangement direction walls 46 protrude in the +Z direction from the base 41. However, the distance between adjacent arrangement direction walls 46 may be set to a distance that does not hold the one-end curved portion 52a. Note that if the one-end curved portion 52a is not to be held by the arrangement direction walls 46, the arrangement direction walls 46 themselves may be omitted.

[0082] (Impedance adjustment section) Next, the impedance adjusting section 60 will be described.

[0083] The extending direction of the impedance adjusting portion 60 of the first terminal 30 is the −Z direction and a diagonal direction inward in the X direction. The extending direction of the impedance adjusting portion 60 of the second terminal 50 is inward in the X direction. The arrangement direction of the impedance adjustment portions 60 of the first terminal 30 and the arrangement direction of the impedance adjustment portions 60 of the second terminal 50 are both the Y direction.

[0084] The impedance adjusting portion 60 of the first terminal 30 and the impedance adjusting portion 60 of the second terminal 50 have the same structure, and therefore will be described together below.

[0085] FIG. 10 is a diagram showing a plurality of impedance adjustment parts 60 arranged in the arrangement direction and extending in the extension direction, viewed from a direction perpendicular to both the extension direction and the arrangement direction. The thickness direction of the impedance adjusting portion 60 is oriented in a direction perpendicular to both the extending direction and the arranging direction. The impedance adjusting portion 60 has a pair of cut surfaces 61. The pair of cut surfaces 61 are outer surfaces of the impedance adjusting portion 60 in the plate width direction, and are cut surfaces formed by cutting the plate material from which the terminals 30 are made.

[0086] The pair of cut surfaces 61 each have a shape in which concaves and convexes are repeated along the extension direction when viewed from the plate thickness direction. Specifically, the cut surfaces 61 have a shape similar to a sine curve when viewed from the plate thickness direction, and are smoothly curved. The cut surface 61 of one impedance adjustment section 60 faces the cut surface 61 of another adjacent impedance adjustment section 60 in the arrangement direction. As a result, in the impedance adjustment section 60, convex sections 61a protruding in a direction toward the adjacent impedance adjustment section 60 and concave sections 61b recessed in a direction away from the adjacent impedance adjustment section 60 are formed alternately along the extension direction.

[0087] The impedance adjusting section 60 has a convex portion 61a and a concave portion 61b on one side in the arrangement direction (left side in FIG. 10), and a convex portion 61a and a concave portion 61b on the other side in the arrangement direction (right side in FIG. 10). The protrusions 61a on one side of the arrangement direction are formed at the same positions in the extension direction as the recesses 61b on the other side of the arrangement direction. Also, the recesses 61b on one side of the arrangement direction are formed at the same positions in the extension direction as the protrusions 61a on the other side of the arrangement direction. Impedance adjusting portions 60 of the same shape are arranged in the arrangement direction. As a result, the recess 61b formed on the cut surface 61 of a certain impedance adjustment section 60 is provided at a position corresponding to the protrusion 61a of the opposing cut surface 61 of the adjacent impedance adjustment section 60.

[0088] <Action and effect> Next, the effects of this embodiment will be described.

[0089] In this embodiment, the connector 100 includes a plurality of terminals 30 and housings 10 and 20. Each of the plurality of terminals 30 has an exposed portion 33. The exposed portion 33 has an impedance adjustment portion 60. The impedance adjustment portion 60 extends in the same direction as the impedance adjustment portions 60 of other terminals 30 at a position adjacent to them. Moreover, in this embodiment, the connector 200 includes a plurality of terminals 50 and a housing 40. Each of the plurality of terminals 50 has an exposed portion 52b. The exposed portion 52b has an impedance adjustment portion 60. The impedance adjustment portion 60 extends in the same direction as the impedance adjustment portions 60 of the other terminals 50 at a position adjacent to them.

[0090] Here, the impedance adjustment section 60 has a convex section 61a that protrudes in a direction toward the adjacent impedance adjustment section 60 and a concave section 61b that is recessed in a direction away from the adjacent impedance adjustment section 60. Therefore, compared to a configuration in which the opposing surfaces (cut surfaces 61) of adjacent impedance adjustment sections 60 extend parallel to the extension direction, the surface area of ​​the opposing surfaces (cut surfaces 61) of adjacent impedance adjustment sections 60 increases, and the impedance of the impedance adjustment sections 60 decreases. As a supplementary note, when inductance is L and capacitance is C, in the high frequency range, impedance is a value close to √L / C. This C is proportional to the surface area of ​​the two conductors lined up side by side. In other words, if the surface area of ​​the two conductors lined up can be increased, the impedance will decrease.

[0091] Furthermore, the recessed portion 61b of the impedance adjusting portion 60 is provided at a position corresponding to the protruding portion 61a of the adjacent impedance adjusting portion 60. Therefore, compared to an embodiment in which the convex portion 61a of the impedance adjustment portion 60 is provided at a position corresponding to the convex portion 61a of an adjacent impedance adjustment portion 60, there are less likely to be small gaps between adjacent impedance adjustment portions 60. As a result, short-circuiting between the terminals 30 is prevented.

[0092] As described above, according to this embodiment, it is possible to reduce the impedance of the exposed portions 33, 52b while preventing short-circuiting between the terminals 30 and between the terminals 50.

[0093] In this embodiment, the convex portion 61a and the concave portion 61b are formed by the cut surface 61. This makes it easy to form the convex portions 61a and the concave portions 61b.

[0094] Incidentally, one method of manufacturing the connectors 100, 200 of this embodiment is to form multiple terminals 30, 50 together by punching and bending processes, and then hold the formed multiple terminals 30, 50 in the housing 10, 20, 40 while they are connected by a carrier (connecting portion). In this method, if there is a small gap between the terminals 30 and 50, a problem arises in the strength of the press die used to form the gap. However, in this embodiment, as described above, since there are less likely to be small gaps between adjacent impedance adjustment units 60, the above problem is less likely to occur. Therefore, the connectors 100 and 200 of this embodiment are suitable for the manufacturing method described above. However, the connectors disclosed herein are not limited to those manufactured by this manufacturing method.

[0095] However, as shown in Figure 8, when terminal 50 has connection portion 51 and fixed side held portion 53, and there is exposed portion 52b between the two, exposed portion 52b tends to have a higher impedance than connection portion 51 and fixed side held portion 53. Therefore, in this embodiment, the impedance adjusting portion 60 is formed between the connecting portion 51 and the fixed-side held portion 53 . Therefore, it is possible to match the impedance between the connection portion 51, the fixed-side held portion 53, and the exposed portion 52b therebetween.

[0096] However, as shown in Figure 4, when terminal 30 has fixed side held portion 32 and movable side held portion 34, and there is exposed portion 33 between them, exposed portion 33 tends to have a higher impedance than fixed side held portion 32 and movable side held portion 34. Therefore, in this embodiment, the impedance adjusting portion 60 is formed between the fixed-side held portion 32 and the movable-side held portion . Therefore, it is possible to match the impedance between the fixed-side held portion 32, the movable-side held portion 34, and the exposed portion 33 therebetween.

[0097] Furthermore, in this embodiment, as shown in FIG. 4, the average width of the impedance adjustment section 60 is larger than the width of the portion (one-end curved portion 33a) connected to one end of the impedance adjustment section 60, and is larger than the width of the portion (other-end curved portion 33c) connected to the other end of the impedance adjustment section 60. Therefore, the impedance of the impedance adjusting section 60 can be further reduced.

[0098] In addition, in this embodiment, as shown in FIG. 10, the convex portion 61a has an arc-shaped edge that is convex in the direction toward the adjacent impedance adjustment portion 60, and the concave portion 61b has an arc-shaped edge that is convex in the direction away from the adjacent impedance adjustment portion 60. Therefore, when the protrusions 61 a and the recesses 61 b ​​are formed by cutting surfaces as in this embodiment, the protrusions and recesses are easily formed. Furthermore, in other cases, the protrusions 61 a and the recesses 61 b ​​are easily formed. Examples of other cases include when the thickness direction of the impedance adjustment section 60 is roughly aligned with the arrangement direction, and the protrusions and recesses are formed by curving the thickness direction in a wave-like manner along the extension direction.

[0099] In this embodiment, the convex portion 61a and the concave portion 61b are formed continuously, that is, there is no part extending linearly in the extension direction between the convex portion 61a and the concave portion 61b. Therefore, compared to an embodiment in which there is a portion extending linearly in the extension direction between the convex portion 61a and the concave portion 61b (for example, the second modified example described below), the convex portion 61a and the concave portion 61b are arranged efficiently, and the number of concaves and convexes can be increased, thereby efficiently increasing the surface area.

[0100] In this embodiment, the cut surface 61 is formed in a smooth shape without corners when viewed in the thickness direction. Therefore, it is easy to form the convex portion 61a and the concave portion 61b by the cut surface 61.

[0101] When the distance in the arrangement direction between one recess 61b and the other recess 61b of the impedance adjustment section 60 is W1 and the distance in the arrangement direction between one protrusion 61a and the other protrusion 61a is W2, the value of W1 / W2 is not particularly limited. However, as shown in Fig. 10, the value of W1 / W2 is preferably 60% or more.

[0102] Furthermore, when the distance in the arrangement direction between the convex portion 61a of one impedance adjustment section 60 and the convex portion 61a of an adjacent impedance adjustment section 60 is defined as D1, the value of D1 is not particularly limited. However, as shown in Fig. 10, D1 is preferably 30% or less of the average width dimension of the impedance adjustment sections 60. Note that D1 may be a negative value.

[0103] The shortest distance D2 in the arrangement direction between adjacent impedance adjustment parts 60 is greater than D1. The value of D2 is not particularly limited, but is preferably equal to or greater than the plate thickness (e.g., 120 μm) of the terminals 30, 50. This is because if the value of D2 is small, when multiple terminals 30, 50 are collectively formed by punching and bending, the strength of the die used for punching may not be ensured, and the terminals may be damaged.

[0104] (Variation) 11 to 13 show impedance adjusting sections of first to third modified examples.

[0105] FIG. 11 shows an impedance adjusting section 60A of a first modified example. The cut surface 61 of the impedance adjusting portion 60A is not a smooth curve when viewed in the thickness direction.

[0106] FIG. 12 shows an impedance adjusting section 60B of a second modified example. In the impedance adjusting section 60B, the protrusions 61a are rectangular, and the recesses 61b are also rectangular, with the extension dimension of the recesses 61b being greater than the extension dimension of the protrusions 61a.

[0107] FIG. 13 shows an impedance adjusting section 60C of a third modified example. In impedance adjusting section 60C, the value of W1 / W2 is 30% or less, and the value of D1 is zero.

[0108] These modified impedance adjustment sections also reduce the impedance of the impedance adjustment section, and can short-circuit the terminals 30 together.
