［本開示の実施形態の説明］
　最初に本開示の実施態様を列挙して説明する。 [Description of embodiments of the present disclosure]
First, embodiments of the present disclosure will be listed and described.
（１）本開示のプレスフィット端子は、回路基板に設けられるスルーホールに挿入されるプレスフィット端子であって、前記プレスフィット端子の挿入方向に延在する基部と、前記基部よりも前記挿入方向における先端側に配されるプレスフィット部と、前記プレスフィット部に対して前記挿入方向と反対側に配されるショルダー部と、を備え、前記プレスフィット部は、一対の弾性接触部と、前記一対の弾性接触部によって囲まれて構成されるスリットと、を有し、前記一対の弾性接触部のそれぞれは、前記スルーホールの内壁に接触して弾性変形可能とされ、前記スリットは、前記挿入方向及び前記基部の幅方向の双方に直交する前記基部の厚さ方向に開口し、前記ショルダー部は、前記挿入方向に交差するとともに前記基部の幅方向に交差する方向に前記基部から突出している。 (1) The press-fit terminal of the present disclosure is a press-fit terminal inserted into a through hole provided in a circuit board, and includes a base extending in the insertion direction of the press-fit terminal, and a base extending in the insertion direction from the base. a press-fit portion disposed on the distal end side of the press-fit portion, and a shoulder portion disposed on the opposite side of the insertion direction with respect to the press-fit portion; the press-fit portion includes a pair of elastic contact portions; a slit surrounded by a pair of elastic contact parts, each of the pair of elastic contact parts being able to be elastically deformed by contacting an inner wall of the through hole, and the slit being surrounded by a pair of elastic contact parts; The shoulder portion is opened in the thickness direction of the base that is perpendicular to both the insertion direction and the width direction of the base, and the shoulder portion protrudes from the base in a direction that intersects with the insertion direction and the width direction of the base. .
　このような構成によると、基部の厚さ方向にプレスフィット端子を並べることにより、プレスフィット端子間の空間距離を確保しつつ、狭いピッチでプレスフィット端子を配置することができる。 According to such a configuration, by arranging the press-fit terminals in the thickness direction of the base, the press-fit terminals can be arranged at narrow pitches while ensuring the spatial distance between the press-fit terminals.
　ショルダー部は挿入方向に交差するとともに基部の幅方向に交差する方向に基部から突出しているから、プレスフィット端子を基部の厚さ方向に並べる場合でも、ショルダー部を治具等により押さえることができる。 The shoulder part protrudes from the base in a direction that intersects the insertion direction and the width direction of the base, so even when press-fit terminals are arranged in the thickness direction of the base, the shoulder part can be held down with a jig, etc. .
（２）前記一対の弾性接触部のそれぞれは、前記挿入方向に直交する前記基部の幅方向に弾性変形可能とされていることが好ましい。 (2) It is preferable that each of the pair of elastic contact portions is elastically deformable in the width direction of the base portion perpendicular to the insertion direction.
　プレスフィット端子をスルーホールに圧入する際、弾性接触部からスルーホールの内壁に対して過大な力が作用して、スルーホールの周縁の回路基板にクラック等が生じる場合がある（回路基板の白化）。隣接するスルーホール間のピッチが狭い場合、回路基板の白化によって、隣接するスルーホール間の絶縁性能が低下することがある。 When press-fitting a press-fit terminal into a through-hole, excessive force is applied from the elastic contact part to the inner wall of the through-hole, which may cause cracks on the circuit board around the through-hole (whitening of the circuit board). ). If the pitch between adjacent through holes is narrow, the insulation performance between adjacent through holes may deteriorate due to whitening of the circuit board.
　上記の構成によれば、プレスフィット部の各弾性接触部は基部の幅方向に弾性変形可能とされるため、プレスフィット端子をスルーホールに挿入する際、回路基板の白化が生じた場合、基部の幅方向について回路基板が損傷しやすくなっている。よって、プレスフィット端子を、基部の幅方向に直交する基部の厚さ方向に並べることにより、回路基板の白化によるプレスフィット端子間の絶縁性能の低下を抑制しやすくなる。したがって、プレスフィット端子を狭ピッチで配置しやすい。 According to the above configuration, each elastic contact part of the press-fit part can be elastically deformed in the width direction of the base, so if whitening of the circuit board occurs when inserting the press-fit terminal into the through-hole, the base The circuit board is more likely to be damaged in the width direction. Therefore, by arranging the press-fit terminals in the thickness direction of the base that is perpendicular to the width direction of the base, it becomes easier to suppress a decrease in insulation performance between the press-fit terminals due to whitening of the circuit board. Therefore, it is easy to arrange the press-fit terminals at a narrow pitch.

　このような構成によると、第１ショルダー部と第２ショルダー部とが設けられることにより、プレスフィット端子をスルーホールに挿入する際に治具等で押さえる面積を確保しやすい。 According to such a configuration, by providing the first shoulder portion and the second shoulder portion, it is easy to secure an area to be pressed with a jig or the like when inserting the press-fit terminal into the through hole.
（４）前記第１ショルダー部は、前記基部の厚さ方向における一方側に前記基部から突出し、前記第２ショルダー部は、前記基部の厚さ方向における他方側に前記基部から突出していることが好ましい。 (4) The first shoulder portion may protrude from the base on one side in the thickness direction of the base, and the second shoulder portion may protrude from the base on the other side in the thickness direction of the base. preferable.
　このような構成によると、プレスフィット端子をスルーホールに挿入する際に、治具等により第１ショルダー部及び第２ショルダー部を安定して押さえることができる。 According to such a configuration, when inserting the press-fit terminal into the through hole, the first shoulder portion and the second shoulder portion can be stably pressed using a jig or the like.
（５）前記第１ショルダー部と前記第２ショルダー部とは、前記基部の幅方向について異なる位置に配されていることが好ましい。 (5) The first shoulder portion and the second shoulder portion are preferably arranged at different positions in the width direction of the base portion.
　このような構成によると、第１ショルダー部と第２ショルダー部とは基部の幅方向について異なる位置に配されるため、プレスフィット端子を基部の厚さ方向に並べた場合にプレスフィット端子間の空間距離を確保しやすい。よって、プレスフィット端子をより一層狭ピッチで配置しやすくなる。 According to such a configuration, since the first shoulder part and the second shoulder part are arranged at different positions in the width direction of the base, when the press-fit terminals are arranged in the thickness direction of the base, the distance between the press-fit terminals is It is easy to ensure spatial distance. Therefore, it becomes easier to arrange the press-fit terminals at even narrower pitches.
（６）前記第１ショルダー部と前記第２ショルダー部とは、前記挿入方向について異なる位置に配されていることが好ましい。 (6) The first shoulder portion and the second shoulder portion are preferably arranged at different positions in the insertion direction.
　このような構成によると、第１ショルダー部と第２ショルダー部とは挿入方向について異なる位置に配されるため、プレスフィット端子を基部の厚さ方向に並べた場合にプレスフィット端子間の空間距離を確保しやすい。よって、プレスフィット端子をより一層狭ピッチで配置しやすくなる。 According to such a configuration, the first shoulder part and the second shoulder part are arranged at different positions in the insertion direction, so when the press-fit terminals are arranged in the thickness direction of the base, the spatial distance between the press-fit terminals is Easy to secure. Therefore, it becomes easier to arrange the press-fit terminals at even narrower pitches.
（７）前記第１ショルダー部と前記第２ショルダー部とは、前記挿入方向について同じ位置に配されていることが好ましい。 (7) The first shoulder portion and the second shoulder portion are preferably arranged at the same position in the insertion direction.
　このような構成によると、第１ショルダー部と第２ショルダー部とは挿入方向について同じ位置に配されるため、プレスフィット端子を挿入方向について小型化しやすい。 According to such a configuration, since the first shoulder portion and the second shoulder portion are arranged at the same position in the insertion direction, it is easy to downsize the press-fit terminal in the insertion direction.
（８）前記基部に接続され、前記基部の幅方向に延びる端子接続部をさらに備えることが好ましい。 (8) Preferably, the device further includes a terminal connecting portion connected to the base and extending in the width direction of the base.
　このような構成によると、端子接続部が基部の幅方向に延びて設けられるから、プレスフィット端子を基部の厚さ方向に並べることができる。 According to such a configuration, since the terminal connection portion is provided extending in the width direction of the base, the press-fit terminals can be arranged in the thickness direction of the base.

　図４に示すように、基部１１は板状をなしている。本実施形態では、基部１１の厚さ方向は左右方向とされ、基部１１の幅方向は前後方向とされている。基部１１の厚さ方向の寸法は、基部１１の幅方向の寸法に比べて小さくなっている。図３に示すように、延設部１２の前側部分は端子接続部１２Ａとされている。端子接続部１２Ａは、フード部３内において前方に突出して配されている。図示しないが、端子接続部１２Ａは、相手コネクタの相手端子が有する筒状の接続筒部内に挿入されるようになっている。 As shown in FIG. 4, the base 11 has a plate shape. In this embodiment, the thickness direction of the base 11 is the left-right direction, and the width direction of the base 11 is the front-rear direction. The dimension of the base 11 in the thickness direction is smaller than the dimension of the base 11 in the width direction. As shown in FIG. 3, the front portion of the extension portion 12 is a terminal connection portion 12A. The terminal connection portion 12A is disposed within the hood portion 3 so as to protrude forward. Although not shown, the terminal connecting portion 12A is inserted into a cylindrical connecting tube portion of a mating terminal of a mating connector.
［プレスフィット部］
　図４及び図６に示すように、プレスフィット部１３は、一対の弾性接触部１５と、一対の弾性接触部１５により囲まれるスリット１６と、を有する。各弾性接触部１５は、概ね細い角棒状をなしている。一対の弾性接触部１５は、挿入方向と直交する基部１１の幅方向（前後方向）について互いに離間するように広がっており、山形状に形成されている。スリット１６は、基部１１の厚さ方向（左右方向）に開口している。スリット１６は上下方向に長い長孔とされている。 [Press fit section]
As shown in FIGS. 4 and 6, the press-fit portion 13 includes a pair of elastic contact portions 15 and a slit 16 surrounded by the pair of elastic contact portions 15. Each elastic contact portion 15 is generally in the shape of a thin rectangular bar. The pair of elastic contact portions 15 extend apart from each other in the width direction (front-back direction) of the base portion 11 orthogonal to the insertion direction, and are formed in a mountain shape. The slit 16 is open in the thickness direction (left-right direction) of the base 11. The slit 16 is a long hole that is vertically long.
　一対の弾性接触部１５は、前後方向について互いに近づく方向に弾性変形可能となっている。前後方向における、自然状態の一対の弾性接触部１５の最大の差し渡し寸法は、スルーホール２３の直径よりも大きく設定されている。図９に示すように、プレスフィット部１３がスルーホール２３に挿入された状態では、一対の弾性接触部１５は互いに近づくように弾性変形し、スルーホール２３の内壁に形成された導体層２４に圧接する。これにより、回路基板２０に対してプレスフィット端子１０が保持されるとともに、回路基板２０とプレスフィット端子１０とが電気的に接続される。 The pair of elastic contact portions 15 can be elastically deformed in a direction toward each other in the front-back direction. The maximum dimension across the pair of elastic contact portions 15 in the natural state in the front-rear direction is set to be larger than the diameter of the through hole 23 . As shown in FIG. 9, when the press-fit portion 13 is inserted into the through hole 23, the pair of elastic contact portions 15 are elastically deformed to approach each other, and the conductor layer 24 formed on the inner wall of the through hole 23 is Pressure contact. Thereby, the press-fit terminal 10 is held on the circuit board 20, and the circuit board 20 and the press-fit terminal 10 are electrically connected.
　図８及び図９に示すように、プレスフィット部１３の下方には、プレスフィット端子１０の挿入方向における端部（下端部）とされる先端部１７が設けられている。先端部１７は、挿入方向に延びており、プレスフィット部１３をスルーホール２３へガイドするべく先細状とされている。 As shown in FIGS. 8 and 9, a tip portion 17 is provided below the press-fit portion 13 and serves as an end portion (lower end portion) of the press-fit terminal 10 in the insertion direction. The distal end portion 17 extends in the insertion direction and is tapered to guide the press fit portion 13 into the through hole 23.
［ショルダー部］
　図５に示すように、本実施形態のショルダー部１４は、第１ショルダー部１４Ａと、第２ショルダー部１４Ｂと、から構成されている。第１ショルダー部１４Ａ及び第２ショルダー部１４Ｂは矩形状をなしている。第１ショルダー部１４Ａ及び第２ショルダー部１４Ｂは、挿入方向に直交するとともに基部１１の幅方向に交差する方向について基部１１から突出している。図７に示すように、第１ショルダー部１４Ａと基部１１とのなす角度Ａ１、及び第２ショルダー部１４Ｂと基部１１とのなす角度Ａ２は、１８０°未満の範囲で規定され、０°及び１８０°のいずれとも異なる有限の角度となっている。これにより、プレスフィット端子１０が基部１１の幅方向（前後方向）に延びる延設部１２を備える場合でも、ショルダー部１４を治具等（図示せず）により押さえることができる。例えば、第１ショルダー部１４Ａと基部１１とのなす角度Ａ１、及び第２ショルダー部１４Ｂと基部１１とのなす角度Ａ２は、９０°とすることができる。 [Shoulder part]
As shown in FIG. 5, the shoulder portion 14 of this embodiment includes a first shoulder portion 14A and a second shoulder portion 14B. The first shoulder portion 14A and the second shoulder portion 14B have a rectangular shape. The first shoulder portion 14A and the second shoulder portion 14B protrude from the base 11 in a direction perpendicular to the insertion direction and intersecting the width direction of the base 11. As shown in FIG. 7, the angle A1 between the first shoulder portion 14A and the base 11 and the angle A2 between the second shoulder portion 14B and the base 11 are defined in a range of less than 180°, and between 0° and 180°. It is a finite angle that is different from any of the degrees. Thereby, even when the press-fit terminal 10 includes the extending portion 12 extending in the width direction (front-back direction) of the base portion 11, the shoulder portion 14 can be held down by a jig or the like (not shown). For example, the angle A1 between the first shoulder portion 14A and the base 11 and the angle A2 between the second shoulder portion 14B and the base 11 can be 90°.
　第１ショルダー部１４Ａは、基部１１から右方（基部１１の厚さ方向における一方側）に突出している。第２ショルダー部１４Ｂは、基部１１から左方（基部１１の厚さ方向における他方側）に突出している。図６に示すように、第１ショルダー部１４Ａは、基部１１の後側かつ下側の端部から延びている。第２ショルダー部１４Ｂは、基部１１の前側の端部であって、下側の端部よりも上側の位置から延びている。第１ショルダー部１４Ａは、第２ショルダー部１４Ｂより下方かつ後方に配されている。 The first shoulder portion 14A protrudes from the base 11 to the right (one side in the thickness direction of the base 11). The second shoulder portion 14B protrudes from the base 11 to the left (the other side in the thickness direction of the base 11). As shown in FIG. 6, the first shoulder portion 14A extends from the rear and lower end of the base portion 11. As shown in FIG. The second shoulder portion 14B is the front end of the base 11 and extends from a position above the lower end. The first shoulder portion 14A is disposed below and rearward of the second shoulder portion 14B.
　プレスフィット端子１０をスルーホール２３に挿入する際には、図８に示すように、プレスフィット端子１０の先端部１７をスルーホール２３に位置合わせした状態で、ショルダー部１４の上面に治具等（図示せず）を押し当てて、先端部１７を上方からスルーホール２３の内部に挿入する。 When inserting the press-fit terminal 10 into the through-hole 23, as shown in FIG. (not shown) and insert the tip 17 into the through hole 23 from above.
　図１及び図１０に示すように、本実施形態の基板用コネクタ１では、複数のプレスフィット端子１０が基部１１の厚さ方向（左右方向）に並んで配置されている。詳細には、複数の第１プレスフィット端子１０Ａが左右方向に一列に並ぶとともに、複数の第２プレスフィット端子１０Ｂが左右方向に一列に並んでいる。また、第１プレスフィット端子１０Ａと第２プレスフィット端子１０Ｂとは基部１１の幅方向（前後方向）に並んでいる。左右方向に並ぶ第１プレスフィット端子１０Ａの列は、左右方向に並ぶ第２プレスフィット端子１０Ｂの列より後方に配されている。 As shown in FIGS. 1 and 10, in the board connector 1 of this embodiment, a plurality of press-fit terminals 10 are arranged side by side in the thickness direction (horizontal direction) of the base 11. Specifically, the plurality of first press-fit terminals 10A are lined up in a line in the left-right direction, and the plurality of second press-fit terminals 10B are lined up in a line in the left-right direction. Further, the first press-fit terminal 10A and the second press-fit terminal 10B are lined up in the width direction (front-back direction) of the base 11. The row of first press-fit terminals 10A arranged in the left-right direction is arranged behind the row of second press-fit terminals 10B arranged in the left-right direction.
　図３に示すように、第１プレスフィット端子１０Ａの基部１１は、第２プレスフィット端子１０Ｂの基部１１よりも上下方向に長い。第１プレスフィット端子１０Ａの延設部１２は、第２プレスフィット端子１０Ｂの延設部１２よりも前後方向に長い。その他の部材については、第１プレスフィット端子１０Ａと第２プレスフィット端子１０Ｂとは同様に構成されている。ハウジング２において、第１プレスフィット端子１０Ａは上段に配置され、第２プレスフィット端子１０Ｂは下段に配置されている。 As shown in FIG. 3, the base 11 of the first press-fit terminal 10A is longer in the vertical direction than the base 11 of the second press-fit terminal 10B. The extending portion 12 of the first press-fit terminal 10A is longer in the front-rear direction than the extending portion 12 of the second press-fit terminal 10B. Regarding other members, the first press-fit terminal 10A and the second press-fit terminal 10B are configured in the same manner. In the housing 2, the first press-fit terminal 10A is arranged at the upper stage, and the second press-fit terminal 10B is arranged at the lower stage.
　図１０に示すように、本実施形態では、複数のプレスフィット端子１０は基部１１の厚さ方向（左右方向）に並んで配置されるから、隣接するプレスフィット端子１０間の空間距離Ｄ１を確保しやすい。よって、プレスフィット端子１０を左右方向に狭ピッチで配置することができる。 As shown in FIG. 10, in this embodiment, the plurality of press-fit terminals 10 are arranged side by side in the thickness direction (left-right direction) of the base 11, so that the spatial distance D1 between adjacent press-fit terminals 10 is ensured. It's easy to do. Therefore, the press-fit terminals 10 can be arranged at narrow pitches in the left-right direction.
　また、基部１１から突出する第１ショルダー部１４Ａと第２ショルダー部１４Ｂとは、挿入方向及び基部１１の幅方向についてそれぞれ異なる位置に配されているから、隣接するプレスフィット端子１０のショルダー部１４同士を離間させやすい。この結果、隣接するプレスフィット端子１０間の空間距離Ｄ１を確保しやすくなるため、プレスフィット端子１０を左右方向により一層狭ピッチで配置しやすくなる。 Further, since the first shoulder portion 14A and the second shoulder portion 14B protruding from the base 11 are arranged at different positions in the insertion direction and the width direction of the base 11, the shoulder portion 14 of the adjacent press-fit terminal 10 Easy to separate them. As a result, it becomes easier to ensure the spatial distance D1 between adjacent press-fit terminals 10, and therefore it becomes easier to arrange the press-fit terminals 10 at a narrower pitch in the left-right direction.
　一般にプレスフィット端子１０を狭ピッチで配置すると、プレスフィット端子１０のスルーホール２３への挿入により回路基板２０の白化が生じた場合に、隣接するスルーホール２３間の絶縁性能が低下して、プレスフィット端子１０同士が短絡することがありうる。本実施形態では、プレスフィット端子１０のプレスフィット部１３は基部１１の幅方向（前後方向）について弾性変形する一対の弾性接触部１５を備えるため、一対の弾性接触部１５は、スルーホール２３の孔縁部の回路基板２０に対して、前後方向に有限の大きさを持った力を及ぼす（図９参照）。このため、回路基板２０の白化によって回路基板２０の絶縁性能が低下する方向は、主として前後方向であると考えられる。基板用コネクタ１において、プレスフィット端子１０は、前後方向に直交する方向（左右方向）に狭ピッチで並べられているため、回路基板２０の白化に起因して回路基板２０の絶縁性能が低下した場合に、プレスフィット端子１０間が短絡しにくくなっている（図１０参照）。 Generally, if the press-fit terminals 10 are arranged at a narrow pitch, if the circuit board 20 becomes white due to the insertion of the press-fit terminals 10 into the through-holes 23, the insulation performance between adjacent through-holes 23 will deteriorate and the press-fit terminals will The fit terminals 10 may be short-circuited. In the present embodiment, the press-fit portion 13 of the press-fit terminal 10 includes a pair of elastic contact portions 15 that are elastically deformed in the width direction (front-back direction) of the base portion 11; A force having a finite magnitude is exerted in the front-rear direction on the circuit board 20 at the edge of the hole (see FIG. 9). Therefore, it is considered that the direction in which the insulation performance of the circuit board 20 deteriorates due to whitening of the circuit board 20 is mainly in the front-back direction. In the board connector 1, the press-fit terminals 10 are arranged at a narrow pitch in the direction perpendicular to the front-rear direction (left-right direction), so the insulation performance of the circuit board 20 has deteriorated due to whitening of the circuit board 20. In this case, the press-fit terminals 10 are less likely to be short-circuited (see FIG. 10).
　なお、図１０に示すように、基板用コネクタ１において前後方向（基部１１の幅方向）におけるプレスフィット端子１０間の間隔Ｓ２は、左右方向（基部１１の厚さ方向）におけるプレスフィット端子１０間の間隔Ｓ１よりも大きく設定されている。これにより、回路基板２０の白化が生じた場合でも、前後方向に並ぶプレスフィット端子１０間での短絡が抑制されるようになっている。 As shown in FIG. 10, in the board connector 1, the distance S2 between the press-fit terminals 10 in the front-rear direction (width direction of the base 11) is the distance S2 between the press-fit terminals 10 in the left-right direction (thickness direction of the base 11). is set larger than the interval S1. Thereby, even if whitening of the circuit board 20 occurs, short circuits between the press-fit terminals 10 arranged in the front-rear direction are suppressed.
＜実施形態１と比較例との比較＞
　次に、本実施形態との比較のために、従来から知られる比較例にかかるプレスフィット端子１１０及び基板用コネクタ１０１について図１１から図１４を参照しつつ説明する。基板用コネクタ１０１は、図１３に示すように、ハウジング１０２と、複数のプレスフィット端子１１０と、を備え、実施形態１と同じ回路基板２０に接続されるように構成されている。以下、実施形態１と同様の部材、配置については説明を省略する場合がある。 <Comparison between Embodiment 1 and Comparative Example>
Next, for comparison with this embodiment, a press-fit terminal 110 and a board connector 101 according to a conventionally known comparative example will be described with reference to FIGS. 11 to 14. As shown in FIG. 13, the board connector 101 includes a housing 102 and a plurality of press-fit terminals 110, and is configured to be connected to the same circuit board 20 as in the first embodiment. Hereinafter, descriptions of members and arrangements similar to those in Embodiment 1 may be omitted.
　図１４に示すように、複数のプレスフィット端子１１０は、複数の第１プレスフィット端子１１０Ａと、複数の第２プレスフィット端子１１０Ｂと、を含む。複数の第１プレスフィット端子１１０Ａは左右方向に一列に並んで配置されている。複数の第２プレスフィット端子１１０Ｂは左右方向に一列に並んで配置されている。第１プレスフィット端子１１０Ａは第２プレスフィット端子１１０Ｂの後方に配されている。 As shown in FIG. 14, the plurality of press-fit terminals 110 include a plurality of first press-fit terminals 110A and a plurality of second press-fit terminals 110B. The plurality of first press-fit terminals 110A are arranged in a line in the left-right direction. The plurality of second press-fit terminals 110B are arranged in a line in the left-right direction. The first press-fit terminal 110A is arranged behind the second press-fit terminal 110B.
　図１３に示すように、プレスフィット端子１１０は、基部１１１と、基部１１１から前方に延びる延設部１１２と、プレスフィット部１１３（図１１参照）と、ショルダー部１１４（図１１参照）と、を備える。図１１に示すように、比較例では、基部１１１の厚さ方向は前後方向とされ、基部１１１の幅方向は左右方向とされている。 As shown in FIG. 13, the press-fit terminal 110 includes a base 111, an extending portion 112 extending forward from the base 111, a press-fit portion 113 (see FIG. 11), and a shoulder portion 114 (see FIG. 11). Equipped with As shown in FIG. 11, in the comparative example, the thickness direction of the base 111 is the front-rear direction, and the width direction of the base 111 is the left-right direction.
　プレスフィット部１１３は、一対の弾性接触部１１５と、スリット１１６と、を有する。図１２に示すように、プレスフィット部１１３の一対の弾性接触部１１５は、左右方向に弾性変形可能とされ、左右方向についてスルーホール２３の内壁に圧接する。スリット１１６は前後方向に開口している。プレスフィット部１１３の下方には先細状の先端部１１７が設けられている。 The press fit part 113 has a pair of elastic contact parts 115 and a slit 116. As shown in FIG. 12, the pair of elastic contact portions 115 of the press-fit portion 113 are elastically deformable in the left-right direction, and press against the inner wall of the through-hole 23 in the left-right direction. The slit 116 is open in the front-rear direction. A tapered tip portion 117 is provided below the press-fit portion 113.
　図１１に示すように、ショルダー部１１４は、基部１１１の下端部から右方に突出する第１ショルダー部１１４Ａと、基部１１１の下端部から左方に突出する第２ショルダー部１１４Ｂと、を備える。 As shown in FIG. 11, the shoulder portion 114 includes a first shoulder portion 114A that protrudes to the right from the lower end of the base 111, and a second shoulder portion 114B that protrudes to the left from the lower end of the base 111. .
　図１４に示すように、比較例にかかる基板用コネクタ１０１では、左右方向において狭ピッチでプレスフィット端子１１０を並べる場合、プレスフィット端子１１０間の空間距離Ｄ２が小さくなりやすい。一方、実施形態１によれば、プレスフィット端子１０間の空間距離Ｄ１（図１０参照）を、比較例にかかるプレスフィット端子１１０間の空間距離Ｄ２の２倍程度とすることができる。 As shown in FIG. 14, in the board connector 101 according to the comparative example, when the press-fit terminals 110 are arranged at a narrow pitch in the left-right direction, the spatial distance D2 between the press-fit terminals 110 tends to become small. On the other hand, according to the first embodiment, the spatial distance D1 (see FIG. 10) between the press-fit terminals 10 can be approximately twice the spatial distance D2 between the press-fit terminals 110 according to the comparative example.
　比較例においては、弾性接触部１１５は左右方向について弾性変形するから、弾性接触部１１５によりスルーホール２３の孔縁部の回路基板２０にかかる力は左右方向に有限の大きさを持つ（図１２参照）。したがって、回路基板２０の白化が生じた場合には回路基板２０の絶縁性能が低下する方向は主として左右方向となる。したがって、左右方向に狭ピッチでプレスフィット端子１１０を並べると、回路基板２０の白化が生じた場合に隣接するスルーホール２３間の短絡が起きやすい（図１４参照）。一方、実施形態１では、前記したように回路基板２０の白化の方向（前後方向）と直交する方向（左右方向）に、プレスフィット端子１０が並んでいるから、左右方向におけるプレスフィット端子１０間のピッチを狭くしやすくなっている（図１０参照）。 In the comparative example, since the elastic contact portion 115 is elastically deformed in the left-right direction, the force applied by the elastic contact portion 115 to the circuit board 20 at the edge of the through-hole 23 has a finite magnitude in the left-right direction (FIG. 12 reference). Therefore, when whitening of the circuit board 20 occurs, the direction in which the insulation performance of the circuit board 20 deteriorates is mainly in the left-right direction. Therefore, when press-fit terminals 110 are arranged at a narrow pitch in the left-right direction, short circuits between adjacent through holes 23 are likely to occur when whitening of the circuit board 20 occurs (see FIG. 14). On the other hand, in the first embodiment, since the press-fit terminals 10 are lined up in the direction (left-right direction) perpendicular to the whitening direction (front-back direction) of the circuit board 20 as described above, the distance between the press-fit terminals 10 in the left-right direction is This makes it easier to narrow the pitch (see Figure 10).
［実施形態１の作用効果］
　実施形態１によれば、以下の作用、効果を奏する。
　実施形態１にかかるプレスフィット端子１０は、回路基板２０に設けられるスルーホール２３に挿入されるプレスフィット端子１０であって、プレスフィット端子１０の挿入方向（下方）に延在する基部１１と、基部１１よりも挿入方向における先端側に配されるプレスフィット部１３と、プレスフィット部１３に対して挿入方向と反対側（上方）に配されるショルダー部１４と、を備え、プレスフィット部１３は、一対の弾性接触部１５と、一対の弾性接触部１５によって囲まれて構成されるスリット１６と、を有し、一対の弾性接触部１５のそれぞれは、スルーホール２３の内壁に接触して弾性変形可能とされ、スリット１６は、挿入方向及び基部１１の幅方向（前後方向）の双方に直交する基部１１の厚さ方向（左右方向）に開口し、ショルダー部１４は、挿入方向に交差するとともに基部１１の幅方向に交差する方向に基部１１から突出している。 [Operations and effects of Embodiment 1]
According to the first embodiment, the following actions and effects are achieved.
The press-fit terminal 10 according to the first embodiment is a press-fit terminal 10 that is inserted into a through hole 23 provided in a circuit board 20, and includes a base 11 that extends in the insertion direction (downward) of the press-fit terminal 10; The press-fit part 13 includes a press-fit part 13 disposed on the distal end side in the insertion direction from the base part 11 and a shoulder part 14 disposed on the opposite side (upper side) of the press-fit part 13 in the insertion direction. has a pair of elastic contact parts 15 and a slit 16 surrounded by the pair of elastic contact parts 15, and each of the pair of elastic contact parts 15 is in contact with the inner wall of the through hole 23. The slit 16 is elastically deformable, and the slit 16 opens in the thickness direction (horizontal direction) of the base 11 that is orthogonal to both the insertion direction and the width direction (front-back direction) of the base 11, and the shoulder part 14 is opened in the thickness direction (left-right direction) that is perpendicular to both the insertion direction and the width direction (front-back direction) of the base 11. At the same time, it protrudes from the base 11 in a direction intersecting the width direction of the base 11.
　このような構成によると、基部１１の厚さ方向にプレスフィット端子１０を並べることにより、プレスフィット端子１０間の空間距離Ｄ１を確保しつつ、狭いピッチでプレスフィット端子１０を配置することができる。 According to such a configuration, by arranging the press-fit terminals 10 in the thickness direction of the base 11, the press-fit terminals 10 can be arranged at narrow pitches while ensuring the spatial distance D1 between the press-fit terminals 10. .
　ショルダー部１４は挿入方向に交差するとともに基部１１の幅方向に交差する方向に基部１１から突出しているから、プレスフィット端子１０を基部１１の厚さ方向に並べる場合でも、ショルダー部１４を治具等により押さえることができる。 Since the shoulder portion 14 protrudes from the base portion 11 in a direction that intersects the insertion direction and the width direction of the base portion 11, even when the press-fit terminals 10 are arranged in the thickness direction of the base portion 11, the shoulder portion 14 can be attached to a jig. It can be suppressed by etc.
　実施形態１では、一対の弾性接触部１５のそれぞれは、挿入方向に直交する基部１１の幅方向に弾性変形可能とされている。 In the first embodiment, each of the pair of elastic contact portions 15 is elastically deformable in the width direction of the base portion 11 orthogonal to the insertion direction.
　プレスフィット端子１０をスルーホール２３に圧入する際、弾性接触部１５からスルーホール２３の内壁に対して過大な力が作用して、スルーホール２３の周縁の回路基板２０にクラック等が生じる場合がある（回路基板の白化）。隣接するスルーホール２３間のピッチが狭い場合、回路基板２０の白化によって、隣接するスルーホール２３間の絶縁性能が低下することがある。 When press-fitting the press-fit terminal 10 into the through-hole 23, excessive force may be applied from the elastic contact portion 15 to the inner wall of the through-hole 23, and cracks may occur on the circuit board 20 at the periphery of the through-hole 23. Yes (whitening of circuit board). If the pitch between adjacent through holes 23 is narrow, the insulation performance between adjacent through holes 23 may deteriorate due to whitening of circuit board 20.
　上記の構成によれば、プレスフィット部１３の各弾性接触部１５は基部１１の幅方向に弾性変形可能とされるため、プレスフィット端子１０をスルーホール２３に挿入する際、回路基板２０の白化が生じた場合、基部１１の幅方向について回路基板２０が損傷しやすくなっている。よって、プレスフィット端子１０を、基部１１の幅方向に直交する基部１１の厚さ方向に並べることにより、回路基板２０の白化によるプレスフィット端子１０間の絶縁性能の低下を抑制しやすくなる。したがって、プレスフィット端子１０を狭ピッチで配置しやすい。 According to the above configuration, since each elastic contact part 15 of the press-fit part 13 is elastically deformable in the width direction of the base part 11, when the press-fit terminal 10 is inserted into the through hole 23, the circuit board 20 becomes white. If this occurs, the circuit board 20 is likely to be damaged in the width direction of the base 11. Therefore, by arranging the press-fit terminals 10 in the thickness direction of the base 11 that is perpendicular to the width direction of the base 11, it becomes easier to suppress a decrease in insulation performance between the press-fit terminals 10 due to whitening of the circuit board 20. Therefore, it is easy to arrange the press-fit terminals 10 at narrow pitches.
　実施形態１では、ショルダー部１４は、第１ショルダー部１４Ａと、第１ショルダー部１４Ａとは異なる第２ショルダー部１４Ｂと、を備える。 In the first embodiment, the shoulder portion 14 includes a first shoulder portion 14A and a second shoulder portion 14B different from the first shoulder portion 14A.

＜実施形態２＞
　本開示の実施形態２について、図１５から図２０を参照しつつ説明する。実施形態２では、プレスフィット端子２１０のプレスフィット部２１３及びショルダー部２１４の構成が実施形態１と異なっている。実施形態２のその他の構成、作用効果については、実施形態１と同様であるから、同一の部材に同一の符号を付して詳細な説明を省略する。 <Embodiment 2>
Embodiment 2 of the present disclosure will be described with reference to FIGS. 15 to 20. In the second embodiment, the configurations of a press-fit portion 213 and a shoulder portion 214 of a press-fit terminal 210 are different from those in the first embodiment. The other configurations and effects of the second embodiment are the same as those of the first embodiment, so the same members are given the same reference numerals and detailed explanations will be omitted.
　プレスフィット端子２１０は、金属板材をプレス加工することで形成されている。金属板材としては、銅、銅合金等、任意の金属が選択される。図２０に示すように、プレスフィット端子２１０の表面には、スズ、ニッケル等の金属を含むメッキ層２１０Ｃが形成されている。本実施形態では、金属板材がプレス加工される前に、金属板材の裏表両面にメッキ処理が施される。すなわち、プレスフィット端子２１０は、基部１１の厚さ方向両側の面にメッキ層２１０Ｃを有する。 The press-fit terminal 210 is formed by pressing a metal plate material. Any metal such as copper or copper alloy is selected as the metal plate material. As shown in FIG. 20, a plating layer 210C containing metal such as tin and nickel is formed on the surface of the press-fit terminal 210. In this embodiment, before the metal plate material is pressed, plating treatment is performed on both the front and back sides of the metal plate material. That is, the press-fit terminal 210 has a plating layer 210C on both sides of the base 11 in the thickness direction.
　また、プレス加工時において剪断刃が金属板材の表面から基部１１の厚さ方向中央に入り込んでいくことによって、金属板材表面のメッキ層が金属板材の表面から内側に引き込まれることが想定される。このため、プレスフィット端子２１０のうち、基部１１の厚さ方向両側の面に連なる、丸みを帯びた角部にも、メッキ層２１０Ｃが存在することが想定される。プレスフィット端子２１０の切断面となる側面、特に、側面における基部１１の厚さ方向中央領域にはメッキ層２１０Ｃが無く、母材が露出していることが想定される。 Furthermore, it is assumed that the plating layer on the surface of the metal plate is drawn inward from the surface of the metal plate as the shearing blade enters the center of the base 11 in the thickness direction from the surface of the metal plate during press working. Therefore, it is assumed that the plating layer 210C is also present in the rounded corners of the press-fit terminal 210 that are continuous with both sides of the base 11 in the thickness direction. It is assumed that there is no plating layer 210C on the side surface of the press-fit terminal 210 that is the cut surface, particularly in the central region in the thickness direction of the base 11 on the side surface, and that the base material is exposed.
［プレスフィット部］
　図１５及び図１７に示すように、プレスフィット部２１３は、一対の弾性接触部２１５と、一対の弾性接触部２１５により囲まれるスリット１６と、を有する。一対の弾性接触部２１５は、基部１１の幅方向（前後方向）及び基部１１の厚さ方向（左右方向）について互いに離間するように広がって形成されている。詳細には、一対の弾性接触部２１５は、図１７に示すように、側面視で全体として前後方向に離間している。さらに、一対の弾性接触部２１５の上下方向中央部は、図１６に示すように、前後方向から見て左右方向に離間して山形状に広がる突出部２１５Ａとされている。 [Press fit section]
As shown in FIGS. 15 and 17, the press-fit portion 213 includes a pair of elastic contact portions 215 and a slit 16 surrounded by the pair of elastic contact portions 215. The pair of elastic contact portions 215 are formed to spread apart from each other in the width direction (front-back direction) of the base 11 and the thickness direction (left-right direction) of the base 11 . Specifically, as shown in FIG. 17, the pair of elastic contact portions 215 are generally separated from each other in the front-rear direction when viewed from the side. Furthermore, as shown in FIG. 16, the vertical center portions of the pair of elastic contact portions 215 are formed into protruding portions 215A that are spaced apart in the left-right direction when viewed from the front-rear direction and widen into a mountain shape.
　プレスフィット部２１３は、挿入方向に直交する方向における、自然状態の一対の弾性接触部２１５の差し渡し寸法が、スルーホール２３の直径よりも大きくなる部分を有している。これにより、図１９に示すように、プレスフィット部２１３がスルーホール２３に挿入された状態では、一対の弾性接触部２１５は互いに近づくように弾性変形し、スルーホール２３の内壁に形成された導体層２４に圧接する。これにより、回路基板２０に対してプレスフィット端子２１０が保持されるとともに、回路基板２０とプレスフィット端子２１０とが電気的に接続される。 The press-fit portion 213 has a portion in which the width of the pair of elastic contact portions 215 in the natural state in the direction perpendicular to the insertion direction is larger than the diameter of the through hole 23 . As a result, as shown in FIG. 19, when the press-fit portion 213 is inserted into the through hole 23, the pair of elastic contact portions 215 are elastically deformed to approach each other, and the conductor formed on the inner wall of the through hole 23 The layer 24 is pressed against the layer 24. Thereby, the press-fit terminals 210 are held on the circuit board 20, and the circuit board 20 and the press-fit terminals 210 are electrically connected.
　前後方向における、自然状態の一対の弾性接触部２１５の差し渡し寸法は、プレスフィット部２１３の挿入方向の両端部を除く領域で、スルーホール２３の直径よりも大きく設定されている（図１７参照）。このため、プレスフィット部２１３をスルーホール２３に挿入すると、スルーホール２３の内壁からプレスフィット部２１３に、前後方向にプレスフィット部２１３を圧縮する力が加えられる。 The width across the pair of elastic contact parts 215 in the natural state in the front-rear direction is set larger than the diameter of the through-hole 23 in the region excluding both ends of the press-fit part 213 in the insertion direction (see FIG. 17). . Therefore, when the press-fit portion 213 is inserted into the through-hole 23, a force is applied from the inner wall of the through-hole 23 to the press-fit portion 213 in the front-rear direction to compress the press-fit portion 213.
　また、図１６に示すように、左右方向における、自然状態の一対の弾性接触部２１５の差し渡し寸法は、突出部２１５Ａの挿入方向中央位置において最大となっている。左右方向における差し渡し寸法の最大値は、スルーホール２３の直径よりも大きく設定されている。このため、プレスフィット部２１３をスルーホール２３に挿入すると、スルーホール２３の内壁から突出部２１５Ａに、左右方向に突出部２１５Ａを圧縮する力が加えられる。 Further, as shown in FIG. 16, the width across the pair of elastic contact parts 215 in the natural state in the left-right direction is maximum at the center position in the insertion direction of the protrusion 215A. The maximum value of the across dimension in the left-right direction is set to be larger than the diameter of the through hole 23. Therefore, when the press-fit portion 213 is inserted into the through hole 23, a force is applied from the inner wall of the through hole 23 to the protrusion 215A in the left-right direction to compress the protrusion 215A.
　図２０は、スルーホール２３に挿入されたプレスフィット端子２１０を、挿入方向における突出部２１５Ａの位置において、挿入方向に直交する方向に切断した断面を示す図である。図２０に示すように、自然状態にある一対の突出部２１５Ａ（図２０の二点鎖線）は前後方向及び左右方向においてスルーホール２３の直径よりも大きい差し渡し寸法を有するため、プレスフィット端子２１０がスルーホール２３に挿入されると、一対の突出部２１５Ａは前後方向及び左右方向の双方と交差する斜め方向に互いに近づくように弾性変形する。よって、突出部２１５Ａの角部とスルーホール２３の内壁とを接触させやすい。突出部２１５Ａの角部にはメッキ層２１０Ｃが設けられているから、プレスフィット端子２１０とスルーホール２３の内壁の導体層２４との電気的な接続を良好にすることができる。 FIG. 20 is a cross-sectional view of the press-fit terminal 210 inserted into the through-hole 23, cut in a direction perpendicular to the insertion direction at the position of the protrusion 215A in the insertion direction. As shown in FIG. 20, the pair of protrusions 215A (double-dot chain lines in FIG. 20) in their natural state have a width dimension larger than the diameter of the through hole 23 in the front-rear direction and left-right direction, so that the press-fit terminal 210 When inserted into the through hole 23, the pair of protrusions 215A are elastically deformed so as to approach each other in an oblique direction that intersects both the front-rear direction and the left-right direction. Therefore, the corner of the protrusion 215A can easily come into contact with the inner wall of the through hole 23. Since the plating layer 210C is provided at the corner of the protrusion 215A, good electrical connection between the press-fit terminal 210 and the conductor layer 24 on the inner wall of the through hole 23 can be achieved.
　図１７に示すように、各弾性接触部２１５は、挿入方向中央部において基部１１の幅方向の内方に凹む凹部２１５Ｂを有する。換言すると、前後方向における、自然状態の一対の弾性接触部２１５の差し渡し寸法は、挿入方向中央部よりも先端部１７寄りの位置と、挿入方向中央部よりも基部１１寄りの位置と、において最大となっており、突出部２１５Ａを含む挿入方向中央部においてやや小さくなっている。凹部２１５Ｂが設けられることにより、各弾性変形部２１５の挿入方向中央部は前後方向（図１７の図示左右方向）に圧縮され、左右方向（図１７の紙面垂直方向）に押し広げられた状態となるから、突出部２１５Ａの左右方向の寸法を大きくすることができる。よって、突出部２１５Ａを左右方向に突出させやすくなる。 As shown in FIG. 17, each elastic contact portion 215 has a recess 215B that is recessed inward in the width direction of the base 11 at the center in the insertion direction. In other words, the across dimension of the pair of elastic contact parts 215 in the natural state in the front-rear direction is maximum at a position closer to the distal end 17 than the center in the insertion direction, and at a position closer to the base 11 than the center in the insertion direction. , and is slightly smaller at the center portion in the insertion direction including the protruding portion 215A. By providing the recess 215B, the center portion of each elastic deformation portion 215 in the insertion direction is compressed in the front-rear direction (left-right direction in FIG. 17) and expanded in the left-right direction (perpendicular to the plane of the paper in FIG. 17). Therefore, the horizontal dimension of the protrusion 215A can be increased. Therefore, the protruding portion 215A can be easily protruded in the left-right direction.
［ショルダー部］
　図１５及び図１８に示すように、ショルダー部２１４は、第１ショルダー部２１４Ａと、第２ショルダー部２１４Ｂと、を備える。第１ショルダー部２１４Ａは、基部１１から右方（基部１１の厚さ方向における一方側）に突出している。第２ショルダー部２１４Ｂは、基部１１から左方（基部１１の厚さ方向における他方側）に突出している。図１５に示すように、第１ショルダー部２１４Ａは、基部１１の後側かつ下側の端部から延びている。第２ショルダー部２１４Ｂは、基部１１の前側かつ下側の端部から延びている。図１６に示すように、第１ショルダー部２１４Ａは、第２ショルダー部２１４Ｂと、上下方向（挿入方向）について同じ位置に配されている。 [Shoulder part]
As shown in FIGS. 15 and 18, the shoulder section 214 includes a first shoulder section 214A and a second shoulder section 214B. The first shoulder portion 214A protrudes from the base 11 to the right (one side in the thickness direction of the base 11). The second shoulder portion 214B protrudes from the base 11 to the left (the other side in the thickness direction of the base 11). As shown in FIG. 15, the first shoulder portion 214A extends from the rear and lower end of the base portion 11. As shown in FIG. The second shoulder portion 214B extends from the front and lower end of the base portion 11. As shown in FIG. 16, the first shoulder portion 214A is arranged at the same position as the second shoulder portion 214B in the vertical direction (insertion direction).
