　本発明は、圧接コンタクトに関する。 The present invention relates to a pressure contact.
　近年、電子機器に内蔵される２つの基板を電気的に接続する手段として、基部と、接点部と、基部及び接点部を連結する弾性部と、を備えた圧接コネクタが利用されている。圧接コネクタの基部を一方の基板の接点に接続し、圧接コネクタの接点部を他方の基板の接点に圧接させることにより、２つの基板を電気的に接続することができる。 In recent years, as a means for electrically connecting two substrates built in an electronic device, a press-connecting connector including a base, a contact portion, and an elastic portion connecting the base and the contact portion has been used. The two substrates can be electrically connected by connecting the base of the press-connecting connector to the contact of one substrate and pressing the contact of the press-connecting connector to the contact of the other substrate.
　従来、圧接コネクタの弾性部として、圧接コネクタの伸縮方向に延びる螺旋形状のものが利用されている。また、圧接コンタクトの展開形状を小型化するために、折り返し部分を有する弾性部も提案されている。 Conventionally, a helical connector extending in the direction of expansion and contraction of the press-connecting connector is used as the elastic portion of the press-connecting connector. Further, an elastic portion having a folded portion has been proposed in order to reduce the developed shape of the press contact.

　図１に示すように、圧接コンタクト１００は、接点部１と、基部２と、弾性部３（図１の第２弾性部３２及び図２の第１弾性部３１）と、を備える。圧接コンタクト１００は、上側（Ｚ２方向側）に配置された上基板と、下側（Ｚ１方向側）に配置された下基板と、の間に実装される。より詳細には、圧接コンタクト１００は、接点部１が上基板の接点に接触し、基部２が下基板の接点に接続され、弾性部３がＺ方向に圧縮された状態で実装される。これにより、接点部１は上基板の接点に圧接されるため、上基板及び下基板の導通を確実に確保することができる。 As shown in FIG. 1, the press contact 100 includes a contact portion 1, a base 2, and an elastic portion 3 (the second elastic portion 32 in FIG. 1 and the first elastic portion 31 in FIG. 2). The pressure contact 100 is mounted between an upper substrate disposed on the upper side (Z2 direction side) and a lower substrate disposed on the lower side (Z1 direction side). More specifically, the press contact 100 is mounted with the contact portion 1 in contact with the contact on the upper substrate, the base 2 connected to the contact on the lower substrate, and the elastic portion 3 compressed in the Z direction. Thereby, the contact portion 1 is pressed against the contact of the upper substrate, so that conduction between the upper substrate and the lower substrate can be reliably ensured.
　接点部１は、弾性部３に支持され、弾性部３の伸縮に伴って移動する可動接点であり、上基板の接点に圧接される。接点部１は、第１接点部１１と、第２接点部１２と、第１カバー部１３と、第２カバー部１４と、を有する。 The contact portion 1 is a movable contact supported by the elastic portion 3 and moved as the elastic portion 3 expands and contracts, and is pressed against the contact on the upper substrate. The contact part 1 has a first contact part 11, a second contact part 12, a first cover part 13, and a second cover part 14.
　第１接点部１１は、上基板の接点に接触し、圧接コンタクト１００の接点として機能する部分である。第１接点部１１は、後述する底板部２１と平行な平板状であり、後述する第１弾性部３１の上端部（Ｚ２方向の端部）からＸ２方向に延びるように形成される。第１接点部１１は、図８に示すように、Ｚ２方向から見た形状が略矩形であり、Ｘ方向と平行な対向する一対の辺と、Ｙ方向と平行な対向する一対の辺と、を有する。なお、本明細書において、略矩形は、矩形と、矩形の一部を切り欠いた形状と、を含むものとする。略矩形の辺とは、矩形の辺に対応する部分のことをいう。 The first contact portion 11 is a portion that contacts the contact on the upper substrate and functions as the contact of the press contact 100. The first contact portion 11 has a flat plate shape parallel to a bottom plate portion 21 described later, and is formed to extend in the X2 direction from an upper end portion (end portion in the Z2 direction) of a first elastic portion 31 described later. As shown in FIG. 8, the first contact portion 11 has a substantially rectangular shape when viewed from the Z2 direction, and has a pair of opposed sides parallel to the X direction, a pair of opposed sides parallel to the Y direction, Having. In this specification, a substantially rectangular shape includes a rectangular shape and a shape obtained by cutting out a part of the rectangular shape. The substantially rectangular side refers to a portion corresponding to the rectangular side.
　第２接点部１２は、弾性部３の圧縮時において、第１接点部１１と接触し、第１接点部１１と共に圧接コンタクト１００の接点として機能する部分である。第２接点部１２は、底板部２１と平行な平板状であり、後述する第２弾性部３２の上端部（Ｚ２方向側の端部）からＸ１方向に延びるように形成される。第２接点部１２は、Ｚ２方向から見た形状が略矩形であり、Ｘ方向と平行な対向する一対の辺と、Ｙ方向と平行な対向する一対の辺と、を有する。第２接点部１２は、第１接点部１１とＺ方向から見て重複するように、第１接点部１１の下側（Ｚ１方向側）に配置される。第２接点部１２は、Ｘ１方向側の辺と、第１接点部１１を支持する第１弾性部３１の上端部と、が衝突しないように形成される。 The second contact portion 12 is a portion that contacts the first contact portion 11 when the elastic portion 3 is compressed, and functions as a contact of the press contact 100 together with the first contact portion 11. The second contact portion 12 has a flat plate shape parallel to the bottom plate portion 21 and is formed to extend in the X1 direction from an upper end portion (an end portion on the Z2 direction side) of a second elastic portion 32 described later. The second contact portion 12 has a substantially rectangular shape when viewed from the Z2 direction, and has a pair of opposing sides parallel to the X direction and a pair of opposing sides parallel to the Y direction. The second contact portion 12 is arranged below the first contact portion 11 (Z1 direction side) so as to overlap with the first contact portion 11 when viewed from the Z direction. The second contact portion 12 is formed such that the side on the X1 direction side does not collide with the upper end of the first elastic portion 31 that supports the first contact portion 11.
　なお、弾性部３の非圧縮時において、第１接点部１１及び第２接点部１２は、接触していてもよいし、離間していてもよい。いずれの場合も、弾性部３のＺ方向の圧縮時には、第１接点部１１が下方（Ｚ１方向）に移動することにより、第１接点部１１及び第２接点部１２は接触する。上述の通り、圧接コンタクト１００は、弾性部３が圧縮された状態で実装されるため、圧接コンタクト１００の実装時には、第１接点部１１及び第２接点部１２は接触している。したがって、圧接コンタクト１００を利用することにより、上基板及び下基板を、第１接点部１１及び第１弾性部３１を通る経路と、第２接点部１２及び第２弾性部３２を通る経路と、の２つの経路を介して電気的に接続することができる。 When the elastic portion 3 is not compressed, the first contact portion 11 and the second contact portion 12 may be in contact with each other or may be separated from each other. In any case, when the elastic portion 3 is compressed in the Z direction, the first contact portion 11 moves downward (Z1 direction), so that the first contact portion 11 and the second contact portion 12 come into contact with each other. As described above, since the press contact 100 is mounted with the elastic portion 3 compressed, the first contact portion 11 and the second contact portion 12 are in contact with each other when the press contact 100 is mounted. Therefore, by using the press contact 100, the upper substrate and the lower substrate can be divided into a path passing through the first contact part 11 and the first elastic part 31, a path passing through the second contact part 12 and the second elastic part 32, Can be electrically connected via the two paths.
　第１カバー部１３は、圧接コンタクト１００の組み立て時や実装時に、作業者の指や軍手（以下「指等」という。）が第１接点部１１及び第２接点部１２のＹ２方向側の辺に引っ掛ることを抑制するための部分である。第１カバー部１３は、図４及び図６に示すように、第２接点部１２のＹ２方向側の辺よりＹ２方向側に位置し、第１接点部１１のＹ２方向側の辺の少なくとも一部からＹ２方向（外向き）に延びるとともに、徐々に下方（Ｚ１方向）へ傾斜するように形成される。第１接点部１１は、第１カバー部１３が第２接点部１２のＹ２方向側の辺よりＹ２方向側に位置するように形成される。具体的には、第１接点部１１のＹ２方向側の辺が、第２接点部１２のＹ２方向側の辺と同じ位置、又は第２接点部１２のＹ２方向側の辺よりＹ２方向側に位置するように、第１接点部１１は形成される。第１カバー部１３は、図５に示すように、Ｙ２方向から見た形状が略矩形であり、Ｘ方向と平行な対向する一対の辺と、Ｚ方向と平行な対向する一対の辺と、を有する。第１カバー部１３を設けることにより、作業者の指等が第１接点部１１及び第２接点部１２のＹ２方向側の辺に触れにくくなるため、圧接コンタクト１００の組み立て時や実装時に、作業者の指等が第１接点部１１及び第２接点部１２のＹ２方向側の辺に引っ掛ることを抑制することができる。なお、第１カバー部１３は、第１接点部１１のＸ１方向側の辺に設けられてもよいし、第１接点部１１のＸ２方向側の辺に設けられてもよいし、２つ以上の辺にそれぞれ設けられてもよい。いずれの場合も、第１カバー部１３は、第１接点部１１の辺の少なくとも一部から外向きに延びるとともに、徐々に下方へ傾斜するように形成される。これにより、作業者の指等を、第１接点部１１及び第２接点部１２における、第１カバー部１３が設けられた辺に触れにくくすることができる。 When assembling or mounting the press contact 100, the first cover 13 is used by a worker's finger or work glove (hereinafter referred to as “finger or the like”) on the Y2 direction side of the first contact portion 11 and the second contact portion 12. This is a part for suppressing the hooking on the device. As shown in FIGS. 4 and 6, the first cover portion 13 is located on the Y2 direction side of the Y2 direction side of the second contact portion 12 and has at least one of the Y2 direction sides of the first contact portion 11. It is formed so as to extend from the portion in the Y2 direction (outward) and to gradually incline downward (Z1 direction). The first contact portion 11 is formed such that the first cover portion 13 is located on the Y2 direction side of the Y2 direction side of the second contact portion 12. Specifically, the side of the first contact portion 11 on the Y2 direction side is located at the same position as the side of the second contact portion 12 on the Y2 direction side, or closer to the Y2 direction side than the side of the second contact portion 12 on the Y2 direction side. The first contact portion 11 is formed so as to be located. As shown in FIG. 5, the first cover portion 13 has a substantially rectangular shape when viewed from the Y2 direction, and has a pair of opposed sides parallel to the X direction, a pair of opposed sides parallel to the Z direction, Having. The provision of the first cover 13 makes it difficult for the operator's finger or the like to touch the sides of the first contact portion 11 and the second contact portion 12 on the Y2 direction side. It is possible to prevent a finger or the like from being caught on the side of the first contact portion 11 and the second contact portion 12 on the Y2 direction side. The first cover portion 13 may be provided on the X1 direction side of the first contact portion 11, may be provided on the X2 direction side of the first contact portion 11, or may be two or more. May be provided on each side. In either case, the first cover portion 13 is formed so as to extend outward from at least a part of the side of the first contact portion 11 and to be gradually inclined downward. Thereby, it is possible to make it difficult for the worker's finger or the like to touch the side of the first contact portion 11 and the second contact portion 12 where the first cover portion 13 is provided.
　第２カバー部１４は、圧接コンタクト１００の組み立て時や実装時に、作業者の指等が第１接点部１１及び第２接点部１２のＹ１方向側の辺に引っ掛ることを抑制するための部分である。第２カバー部１４は、図４及び図６に示すように、第１接点部１１のＹ１方向側の辺よりＹ１方向側に位置し、第２接点部１２のＹ１方向側の辺の少なくとも一部からＹ１方向（外向き）に延びるとともに、徐々に下方（Ｚ１方向）へ傾斜するように形成される。第２接点部１２は、第２カバー部１４が第１接点部１１のＹ１方向側の辺よりＹ１方向側に位置するように形成される。具体的には、第２接点部１２のＹ１方向側の辺が、第１接点部１１のＹ１方向側の辺と同じ位置、又は第１接点部１１のＹ１方向側の辺よりＹ１方向側に位置するように、第２接点部１２は形成される。第２カバー部１４は、図３に示すように、Ｙ１方向から見た形状が略矩形であり、Ｘ方向と平行な対向する一対の辺と、Ｚ方向と平行な対向する一対の辺と、を有する。第２カバー部１４を設けることにより、作業者の指等が第１接点部１１及び第２接点部１２のＹ１方向側の辺に触れにくくなるため、圧接コンタクト１００の組み立て時や実装時に、作業者の指等が第１接点部１１及び第２接点部１２のＹ１方向側の辺に引っ掛ることを抑制することができる。なお、第２カバー部１４は、第２接点部１２のＸ１方向側の辺に設けられてもよいし、第２接点部１２のＸ２方向側の辺に設けられてもよいし、２つ以上の辺にそれぞれ設けられてもよい。いずれの場合も、第２カバー部１４は、第２接点部１２の辺の少なくとも一部から外向きに延びるとともに、徐々に下方へ傾斜するように形成される。これにより、作業者の指等を、第１接点部１１及び第２接点部１２における、第２カバー部１４が設けられた辺に触れにくくすることができる。 The second cover part 14 is a part for suppressing a worker's finger or the like from being caught on the Y1 direction side of the first contact part 11 and the second contact part 12 when the press contact 100 is assembled or mounted. It is. As shown in FIGS. 4 and 6, the second cover portion 14 is located on the Y1 direction side of the Y1 direction side of the first contact portion 11 and at least one of the Y1 direction sides of the second contact portion 12. It is formed so as to extend from the portion in the Y1 direction (outward) and to gradually incline downward (Z1 direction). The second contact portion 12 is formed such that the second cover portion 14 is located on the Y1 direction side of the Y1 direction side of the first contact portion 11. Specifically, the side of the second contact portion 12 on the Y1 direction side is at the same position as the side of the first contact portion 11 on the Y1 direction side or on the Y1 direction side of the side of the first contact portion 11 on the Y1 direction side. The second contact portion 12 is formed so as to be located. As shown in FIG. 3, the second cover portion 14 has a substantially rectangular shape when viewed from the Y1 direction, and has a pair of opposed sides parallel to the X direction, a pair of opposed sides parallel to the Z direction, Having. The provision of the second cover portion 14 makes it difficult for a worker's finger or the like to touch the sides of the first contact portion 11 and the second contact portion 12 on the Y1 direction side. It is possible to prevent a finger or the like from being caught on the Y1 direction side of the first contact portion 11 and the second contact portion 12. The second cover portion 14 may be provided on a side of the second contact portion 12 on the X1 direction side, may be provided on a side of the second contact portion 12 on the X2 direction side, or may be two or more. May be provided on each side. In any case, the second cover portion 14 is formed so as to extend outward from at least a part of the side of the second contact portion 12 and to be gradually inclined downward. Thereby, it is possible to make it difficult for the operator's finger or the like to touch the side of the first contact portion 11 and the second contact portion 12 where the second cover portion 14 is provided.
　なお、接点部１の構成は、図の例に限られない。例えば、第１接点部１１上に上基板と嵌合する凸部が設けられてもよい。凸部と上基板とを嵌合させることにより、上基板に対する接点部１のＸＹ方向の位置ずれを抑制できる。また、第１カバー部１３及び第２カバー部１４を備えない構成も可能である。また、第１接点部１１、第２接点部１２、第１カバー部１３、及び第２カバー部１４の形状は略矩形に限られず、任意に設計可能である。 構成 The configuration of the contact section 1 is not limited to the example shown in the figure. For example, a convex portion that fits on the upper substrate may be provided on the first contact portion 11. By fitting the convex portion and the upper substrate, displacement of the contact portion 1 in the XY directions with respect to the upper substrate can be suppressed. A configuration without the first cover 13 and the second cover 14 is also possible. Further, the shapes of the first contact portion 11, the second contact portion 12, the first cover portion 13, and the second cover portion 14 are not limited to a substantially rectangular shape, and can be arbitrarily designed.
　基部２は、下基板に固定される固定接点であり、下基板の接点に接続される。基部２は、底板部２１と、スペーサ部２２と、を有する。 The base 2 is a fixed contact fixed to the lower substrate, and is connected to a contact on the lower substrate. The base 2 has a bottom plate 21 and a spacer 22.
　底板部２１は、弾性部３を支持する部分であり、第１接点部１１及び第２接点部１２と平行な平板状である。底板部２１は、図７に示すように、Ｚ１方向から見た主面の形状が略矩形であり、Ｘ方向と平行な対向する一対の辺Ｅ１，Ｅ２と、Ｙ方向と平行な対向する一対の辺Ｅ３，Ｅ４と、を有する。辺Ｅ１（第１辺）はＹ２方向側の辺であり、辺Ｅ２（第２辺）はＹ１方向側の辺であり、辺Ｅ３（第３辺）はＸ１方向側の辺であり、辺Ｅ４（第４辺）はＸ２方向側の辺である。辺Ｅ１，Ｅ２と辺Ｅ３，Ｅ４とは直交する。 The bottom plate portion 21 is a portion that supports the elastic portion 3 and is a flat plate parallel to the first contact portion 11 and the second contact portion 12. As shown in FIG. 7, the bottom plate portion 21 has a substantially rectangular main surface viewed from the Z1 direction, and a pair of opposing sides E1 and E2 parallel to the X direction and a pair of opposing sides parallel to the Y direction. And sides E3 and E4. Side E1 (first side) is a side on the Y2 direction side, side E2 (second side) is a side on the Y1 direction side, side E3 (third side) is a side on the X1 direction side, and a side E4 (Fourth side) is a side on the X2 direction side. The sides E1, E2 are orthogonal to the sides E3, E4.
　底板部２１は、Ｙ方向と平行な複数のスリット２３を有する。複数のスリット２３は、辺Ｅ１及び辺Ｅ２からＹ方向（Ｚ１方向に対して垂直な方向）に互い違いに延びるように形成される。より詳細には、複数のスリット２３は、それぞれＸ方向の位置が異なるように形成され、辺Ｅ１から延びるスリット２３と、辺Ｅ２から延びるスリット２３と、がＸ方向に交互に並ぶように配置される。図の例では、底板部２１は、４つのスリット２３を有するが、スリット２３の数は任意である。スリット２３を設けることにより、底板部２１は、スリット２３の先端を支点としてＺ方向に弾性変形可能となる。これにより、底板部２１のＺ方向の弾性力が高くなるため、圧接コンタクト１００のＺ方向の弾性力を高めることができる。 The bottom plate 21 has a plurality of slits 23 parallel to the Y direction. The plurality of slits 23 are formed so as to alternately extend in the Y direction (direction perpendicular to the Z1 direction) from the sides E1 and E2. More specifically, the plurality of slits 23 are formed so as to have different positions in the X direction, and are arranged such that the slits 23 extending from the side E1 and the slits 23 extending from the side E2 are alternately arranged in the X direction. You. In the illustrated example, the bottom plate 21 has four slits 23, but the number of slits 23 is arbitrary. By providing the slit 23, the bottom plate portion 21 can be elastically deformed in the Z direction using the tip of the slit 23 as a fulcrum. Accordingly, the elastic force in the Z direction of the bottom plate portion 21 increases, so that the elastic force of the press contact 100 in the Z direction can be increased.

Further, the slit 23 may be inclined with respect to the Y direction. Further, the length of each slit 23 is preferably longer than half of the length of sides E3 and E4. Thereby, the fulcrum of elastic deformation of the bottom plate 21 (the tip of the slit 23) moves away from the point of action (sides E1, E2), so that the bottom plate 21 is more easily elastically deformed, and the elastic force of the bottom plate 21 in the Z direction. Can be further increased.

It has a U-shape having a folded portion and an upper portion extending in the Y2 direction from the upper end of the folded portion. The fourth portion 31d is formed such that the end of the lower portion in the Y2 direction is located closer to the Y2 direction than the end of the upper portion in the Y2 direction. In addition, the turned-back portion of the fourth portion 31d is lightened in a substantially circular shape.

　以上のような構成により、第１弾性部３１に荷重が加わると、第３部分３１ｃ及び第５部分３１ｅが下方に移動することにより、第１弾性部３１が圧縮されると共に、第１部分３１ａを介して、底板部２１の辺Ｅ１に荷重が加わる。この結果、底板部２１における、第１部分３１ａと辺Ｅ１との接続部分の周辺部が、当該接続部分に隣接するスリット２３の先端を支点として弾性変形する。このように、第１弾性部３１と共に底板部２１を弾性変形させることにより、圧接コンタクト１００の弾性力を高めることができる。 With the above-described configuration, when a load is applied to the first elastic portion 31, the third portion 31c and the fifth portion 31e move downward, so that the first elastic portion 31 is compressed and the first portion 31a. , A load is applied to the side E1 of the bottom plate portion 21.

Similarly, the fifth portion 31e does not overlap with the third portion 31c when viewed from the Z direction. Therefore, when a load is applied to the first elastic portion 31, the fifth portion 31e can move downward without colliding with the third portion 31c. As described above, by increasing the distance that the third portion 31c and the fifth portion 31e can move downward, the stroke of the first elastic portion 31 in the Z direction can be increased.

　以上のような構成により、第２弾性部３２に荷重が加わると、第３部分３２ｃ及び第５部分３２ｅが下方に移動することにより、第２弾性部３２が圧縮されると共に、第１部分３２ａを介して、底板部２１の辺Ｅ２に荷重が加わる。この結果、底板部２１における、第１部分３２ａと辺Ｅ２との接続部分の周辺部が、当該接続部分に隣接するスリット２３の先端を支点として弾性変形する。このように、第２弾性部３２と共に底板部２１を弾性変形させることにより、圧接コンタクト１００の弾性力を高めることができる。 With the above configuration, when a load is applied to the second elastic portion 32, the third portion 32c and the fifth portion 32e move downward, so that the second elastic portion 32 is compressed and the first portion 32a , A load is applied to the side E2 of the bottom plate portion 21. As a result, the periphery of the connection portion between the first portion 32a and the side E2 in the bottom plate portion 21 is elastically deformed with the tip of the slit 23 adjacent to the connection portion as a fulcrum.

　弾性部３が螺旋形状である場合、弾性部３の展開形状が直線的に延びる長い帯状となり、圧接コンタクト１００の展開形状が大型化する（展開形状の最大寸法が大きくなる）。これに対して、本実施形態では、弾性部３が折り返し部分を有する形状とすることにより、図９に示すように、弾性部３の展開形状が折り返し部分を有する帯状（Ｓ字状）とし、圧接コンタクト１００の展開形状を小型化（展開形状の最大寸法を小さく）することができる。 (4) When the elastic portion 3 has a spiral shape, the expanded shape of the elastic portion 3 becomes a long strip extending linearly, and the expanded shape of the press contact 100 increases (the maximum dimension of the expanded shape increases). On the other hand, in the present embodiment, by forming the elastic portion 3 into a shape having a folded portion, as shown in FIG. 9, the developed shape of the elastic portion 3 becomes a band shape (S-shaped) having a folded portion, The developed shape of the press contact 100 can be reduced (the maximum dimension of the developed shape can be reduced).

At this time, the developed shapes may be punched out one by one from the metal plate, or each of the developed shapes may be cut off after punching out a shape in which a plurality of developed shapes are connected from the metal plate.
　次に、曲げ加工により、脚部２４及び接続部２５を曲げ、スペーサ部２２を形成する（ステップＳ１０２）。具体的には、図９における底板部２１から接続部２５までに含まれる曲げ部分を曲げることにより、スペーサ部２２が形成される。 Next, the leg portion 24 and the connection portion 25 are bent by bending to form the spacer portion 22 (step S102). Specifically, the spacer portion 22 is formed by bending a bent portion included from the bottom plate portion 21 to the connection portion 25 in FIG.
　続いて、曲げ加工により、弾性部３を組み立てる（ステップＳ１０３）。具体的には、図９における第１部分３１ａから第６部分３１ｆまでに含まれる曲げ部分を曲げることにより、第１弾性部３１が組み立てられ、第１部分３２ａから第６部分３２ｆまでに含まれる曲げ部分を曲げることにより、第２弾性部３２が組み立てられる。また、第６部分３１ｆから第１カバー部１３までに含まれる曲げ部分を曲げることにより、第１接点部１１及び第１カバー部１３が組み立てられ、第６部分３２ｆから第２カバー部１４までに含まれる曲げ部分を曲げることにより、第２接点部１２及び第２カバー部１４が組み立てられる。 Next, the elastic part 3 is assembled by bending (step S103). Specifically, the first elastic portion 31 is assembled by bending a bent portion included in the first portion 31a to the sixth portion 31f in FIG. 9 and included in the first portion 32a to the sixth portion 32f. By bending the bent portion, the second elastic portion 32 is assembled. In addition, the first contact portion 11 and the first cover portion 13 are assembled by bending a bent portion included from the sixth portion 31f to the first cover portion 13, and the first contact portion 11 and the first cover portion 13 are assembled from the sixth portion 32f to the second cover portion 14. By bending the included bending portion, the second contact portion 12 and the second cover portion 14 are assembled.
　弾性部３の組み立て後、曲げ加工により、第２弾性部３２を立ち上げる（ステップＳ１０４）。具体的には、図９における第１部分３２ａと底板部２１との間の曲げ部分を曲げる。これにより、第２接点部１２、第２カバー部１４、及び第２弾性部３２が形成される。 (4) After the assembly of the elastic part 3, the second elastic part 32 is started up by bending (step S104). Specifically, a bent portion between the first portion 32a and the bottom plate portion 21 in FIG. 9 is bent. Thereby, the second contact portion 12, the second cover portion 14, and the second elastic portion 32 are formed.
　その後、曲げ加工により、第１弾性部３１を立ち上げる（ステップＳ１０５）。具体的には、図９における第１部分３１ａと底板部２１との間の曲げ部分を曲げる。これにより、第１接点部１１、第１カバー部１３、及び第１弾性部３１が形成される。第１接点部１１、第１カバー部１３、及び第１弾性部３１は、第１弾性部３１を立ち上げる際に、第２接点部１２、第２カバー部１４、及び第２弾性部３２と衝突しないように形成される。 Thereafter, the first elastic portion 31 is started up by bending (step S105). Specifically, a bent portion between the first portion 31a and the bottom plate portion 21 in FIG. 9 is bent. Thereby, the first contact portion 11, the first cover portion 13, and the first elastic portion 31 are formed. When the first contact portion 11, the first cover portion 13, and the first elastic portion 31 rise the first elastic portion 31, the second contact portion 12, the second cover portion 14, and the second elastic portion 32 It is formed so as not to collide.
　以上により、圧接コンタクト１００が完成する。なお、圧接コンタクト１００の製造方法は、図１０の例に限られない。例えば、スペーサ部２２は、弾性部３の組み立て後、又は弾性部３の形成後に行ってもよい。また、第２接点部１２、第２カバー部１４、及び第２弾性部３２の形成後に、第１接点部１１、第１カバー部１３、及び第１弾性部３１を組み立ててもよい。 Thus, the pressure contact 100 is completed. The method of manufacturing the press contact 100 is not limited to the example of FIG. For example, the spacer portion 22 may be formed after the elastic portion 3 is assembled or after the elastic portion 3 is formed. Further, after forming the second contact portion 12, the second cover portion 14, and the second elastic portion 32, the first contact portion 11, the first cover portion 13, and the first elastic portion 31 may be assembled.
　完成した圧接コンタクト１００は、上基板及び下基板の間に実装される。具体的には、圧接コンタクト１００は、スペーサ部２２を下基板の接点に接続され、接点部１が上基板の接点に接触した状態で圧縮される。これにより、接点部１が上基板の接点に圧接されるため、上基板及び下基板の導通を確実に確保することができる。 (4) The completed pressure contact 100 is mounted between the upper substrate and the lower substrate. Specifically, the press contact 100 is compressed with the spacer portion 22 connected to the contact on the lower substrate and the contact portion 1 in contact with the contact on the upper substrate. Thereby, the contact portion 1 is pressed against the contact of the upper substrate, so that conduction between the upper substrate and the lower substrate can be reliably ensured.
　以上説明した通り、本実施形態によれば、底板部２１に複数のスリット２３が形成され、底板部２１の下側に、下基板と底板部２１との間の隙間を確保するスペーサ部２２が設けられる。このような構成により、底板部２１は、スリット２３の先端を支点としてＺ方向に弾性変形可能となる。これにより、底板部２１のＺ方向の弾性力が高くなるため、圧接コンタクト１００のＺ方向の弾性力を高めることができる。すなわち、本実施形態によれば、高い弾性力を有する圧接コンタクト１００を提供することができる。 As described above, according to the present embodiment, the plurality of slits 23 are formed in the bottom plate portion 21, and the spacer portion 22 that secures a gap between the lower substrate and the bottom plate portion 21 is provided below the bottom plate portion 21. Provided. With such a configuration, the bottom plate portion 21 can be elastically deformed in the Z direction with the tip of the slit 23 as a fulcrum. Accordingly, the elastic force in the Z direction of the bottom plate portion 21 increases, so that the elastic force of the press contact 100 in the Z direction can be increased. That is, according to the present embodiment, it is possible to provide the press contact 100 having high elastic force.
　また、Ｙ１方向に延びる第２カバー部１４が第１接点部１１に設けられている場合、第１弾性部３１を立ち上げる際に、第２カバー部１４と第２接点部１２とが衝突するため、第１弾性部３１の立ち上げが困難になる。同様に、Ｙ２方向に延びる第１カバー部１３が第２接点部１２に設けられている場合、第１弾性部３１を立ち上げる際に、第１カバー部１３と第１接点部１１とが衝突するため、第１弾性部３１の立ち上げが困難になる。これに対して、本実施形態によれば、第１カバー部１３が第１接点部１１に設けられ、第２カバー部１４が第２接点部１２に設けられているため、上記のような衝突が生じず、第１弾性部３１の立ち上げが容易である。この結果、圧接コンタクト１００を容易に製造することができる。 Further, when the second cover portion 14 extending in the Y1 direction is provided on the first contact portion 11, when the first elastic portion 31 is raised, the second cover portion 14 and the second contact portion 12 collide. Therefore, it is difficult to raise the first elastic portion 31. Similarly, when the first cover portion 13 extending in the Y2 direction is provided on the second contact portion 12, when the first elastic portion 31 is started, the first cover portion 13 and the first contact portion 11 collide. Therefore, it is difficult to start up the first elastic portion 31. On the other hand, according to the present embodiment, since the first cover portion 13 is provided on the first contact portion 11 and the second cover portion 14 is provided on the second contact portion 12, the collision as described above occurs. Does not occur, and the rising of the first elastic portion 31 is easy. As a result, the press contact 100 can be easily manufactured.
　なお、上記実施形態に挙げた構成等に、その他の要素との組み合わせなど、ここで示した構成に本発明が限定されるものではない。これらの点に関しては、本発明の趣旨を逸脱しない範囲で変更可能であり、その応用形態に応じて適切に定めることができる。 Note that the present invention is not limited to the configurations shown here, such as combinations of the configurations described in the above embodiment with other elements. These points can be changed without departing from the spirit of the present invention, and can be appropriately determined according to the application form.
