Description

本発明は、圧接コンタクトに関する。   The present invention relates to a pressure contact.

電子機器に内蔵される複数の基板間の電気的接続を実現する手段として、圧接コンタクトを用いた接続構造が従来から提供されている。この接続構造は、弾性変形可能な接触部を備えた圧接コンタクトを一方の基板上に実装し、接触部に対向させて他方の基板の導電部を押し付けることにより、電気的接続を図るものである。   A connection structure using a pressure contact has conventionally been provided as a means for achieving electrical connection between a plurality of substrates incorporated in an electronic device. In this connection structure, a pressure contact having an elastically deformable contact portion is mounted on one of the substrates, and electrical connection is achieved by opposing the contact portion and pressing the conductive portion of the other substrate. .

下記の特許文献１には、上側平板部と、下側平板部と、第１ばね部と、第２ばね部と、を備えた圧接コネクタが開示されている。この圧接コネクタにおいて、第１ばね部は、上側平板部の一端と下側平板部の一端とを連結し、第２ばね部は、上側平板部の下方に位置する補助板と下側平板部の他端とを連結する。第１ばね部と第２ばね部とは、同じ方向に巻回され、伸縮した際に互いに干渉しない位置に配置されている。この構成において、上側平板部は、下側に僅かに移動すると補助板に接し、さらに下側に移動すると補助板とともに下方に移動する。そのため、上側平板部の下方への移動に伴って、上側平板部に繋がる第１ばね部と補助板に繋がる第２ばね部との双方が圧縮されて大きな圧力が発生する。   Patent Document 1 below discloses a pressure-connecting connector provided with an upper flat portion, a lower flat portion, a first spring portion, and a second spring portion. In this pressure-connecting connector, the first spring portion connects one end of the upper flat plate portion to one end of the lower flat plate portion, and the second spring portion is an auxiliary plate located below the upper flat plate portion and the lower flat plate portion. Connect with the other end. The first spring portion and the second spring portion are wound in the same direction, and are arranged at positions where they do not interfere with each other when expanded or contracted. In this configuration, the upper flat plate portion contacts the auxiliary plate when moving slightly downward, and moves downward with the auxiliary plate when moving further downward. Therefore, with the downward movement of the upper flat plate, both the first spring connected to the upper flat and the second spring connected to the auxiliary plate are compressed to generate a large pressure.

近年、電子機器の小型化、構成部品の高集積化等に伴い、圧接コンタクトの微細化が進んでいる。また、圧接コンタクトに振動や衝撃が加わった場合でも、電気的接続の信頼性が高い圧接コンタクトが求められている。ところが、場合によっては圧接コンタクトに外力が加わった際に塑性変形が生じるおそれがある。このような事情から、外力が加わった際に塑性変形しにくい圧接コンタクトの実現が望まれている。   In recent years, with miniaturization of electronic devices and high integration of component parts, etc., miniaturization of pressure-contacts has progressed. In addition, even when vibration or impact is applied to the pressure contact, a pressure contact having high reliability of the electrical connection is required. However, in some cases, plastic deformation may occur when an external force is applied to the pressure contact. Under such circumstances, it is desirable to realize a pressure contact which is less likely to be plastically deformed when an external force is applied.

本発明の一つの態様は、上記の課題を解決するためになされたものであって、電気的接続の信頼性を確保しつつ、塑性変形しにくい圧接コンタクトを実現することを目的の一つとする。   SUMMARY OF THE INVENTION One aspect of the present invention is made to solve the above-mentioned problems, and it is an object of the present invention to realize a pressure contact which is less likely to be plastically deformed while securing the reliability of electrical connection. .

上記の目的を達成するために、本発明の一つの態様の圧接コンタクトは、第１面と第２面とを有する第１板部と、前記第１板部に設けられ、前記第１板部の前記第１面の側に位置する脚部と、伸縮方向が前記第１板部と交差するように設けられた第１ばね部と、前記第１ばね部に設けられた接触部と、を備え、前記第１ばね部の第１端部が、前記脚部と一体的に形成され、前記第１ばね部の第２端部が、前記第１板部の前記第２面の側の空間に延在し、前記接触部が、前記第１ばね部の前記第２端部に設けられ、前記第１ばね部が、前記伸縮方向に平行な仮想軸の周りに巻回された板体で構成され、前記第１ばね部を構成する前記板材の板面は、少なくとも一部が前記第１板部の端面と対向して配置されている。   In order to achieve the above object, the pressure contact according to one aspect of the present invention is provided on a first plate portion having a first surface and a second surface, and the first plate portion, wherein the first plate portion is provided. A leg portion positioned on the side of the first surface, a first spring portion provided so that the expansion / contraction direction intersects the first plate portion, and a contact portion provided on the first spring portion The first end portion of the first spring portion is integrally formed with the leg portion, and the second end portion of the first spring portion is a space on the second surface side of the first plate portion. And the contact portion is provided at the second end of the first spring portion, and the first spring portion is a plate wound around a virtual axis parallel to the expansion and contraction direction.

As a result, the spring span of the first spring portion can be easily lengthened, and the first spring portion is easily displaced. Therefore, the reliability of the electrical connection can be ensured even when vibration or an impact is applied.

水平板部２は、板面が水平面（ｘｙ平面）と平行に設けられ、下面２ａ（第１面）と上面２ｂ（第２面）とを有する。図３に示すように、水平板部２は、上面２ｂの法線方向から見て、中央に開口部２ｈを有し、開口部２ｈを隔てて対向する２枚の水平板部から構成されている。これら２枚の水平板部を区別して説明する際には、適宜、第１水平板部２１、第２水平板部２２と称することもある。第１水平板部２１と第２水平板部２２とは、後述する仮想軸Ｃを中心として回転対称の形状を呈し、各々はｘ軸方向を長手方向、ｙ軸方向を短手方向とする細長い形状に形成されている。   The horizontal plate portion 2 is provided with a plate surface in parallel with a horizontal plane (xy plane), and has a lower surface 2a (first surface) and an upper surface 2b (second surface). As shown in FIG. 3, the horizontal plate 2 has an opening 2h at the center as viewed in the normal direction of the upper surface 2b, and is composed of two horizontal plates facing each other across the opening 2h. There is. When the two horizontal plate portions are distinguished and described, they may be referred to as the first horizontal plate portion 21 and the second horizontal plate portion 22 as appropriate. The first horizontal plate portion 21 and the second horizontal plate portion 22 have a rotationally symmetrical shape with a virtual axis C described later as a center, and each has a longitudinal direction in the x-axis direction and a short direction in the y-axis direction. It is formed in shape.

図１および図２に示すように、垂直板部３は、水平板部２の両端に設けられた第１垂直板部３１（第１脚板部）と第２垂直板部３２（第２脚板部）とで構成されている。第１垂直板部３１および第２垂直板部３２は、板面が垂直面（ｙｚ平面）と平行に設けられている。第１垂直板部３１は、長手方向がｙ軸方向を向くように、第１水平板部２１の一端と第２水平板部２２の一端にわたって延びている。同様に、第２垂直板部３２は、長手方向がｙ軸方向を向くように、第１水平板部２１の他端と第２水平板部２２の他端にわたって延びている。このように、開口部２ｈの周囲に連続して設けられた第１水平板部２１、第１垂直板部３１、第２水平板部２２、および第２垂直板部３２によって、変形しにくい強固な固定部分が形成される。   As shown in FIGS. 1 and 2, the vertical plate portion 3 includes a first vertical plate portion 31 (first leg plate portion) and a second vertical plate portion 32 (second leg plate portion) provided at both ends of the horizontal plate portion 2. And consists of. The plate surfaces of the first vertical plate portion 31 and the second vertical plate portion 32 are provided in parallel with the vertical surface (yz plane). The first vertical plate portion 31 extends over one end of the first horizontal plate portion 21 and one end of the second horizontal plate portion 22 so that the longitudinal direction is in the y-axis direction. Similarly, the second vertical plate portion 32 extends over the other end of the first horizontal plate portion 21 and the other end of the second horizontal plate portion 22 so that the longitudinal direction is in the y-axis direction. As described above, the first horizontal plate portion 21, the first vertical plate portion 31, the second horizontal plate portion 22, and the second vertical plate portion 32 continuously provided around the opening 2 h are not easily deformed. The fixed part is formed.

第１垂直板部３１の一端の下面側には、第１垂直板部３１から下面側に略直角に折り曲げられた折曲部３１１が設けられている。同様に、第２垂直板部３２の一端の下面側には、第２垂直板部３２から下面側に略直角に折り曲げられた折曲部３２１が設けられている。図３に示すように、第１垂直板部３１の折曲部３１１と第２垂直板部３２の折曲部３２１とは、水平板部２の上面２ｂの法線方向から見たとき、圧接コンタクト１の同じ対角線上の両端に位置している。折曲部３１１および折曲部３２１は、図示を省略した回路基板の回路パターンに半田付けされて取り付けられる。   On the lower surface side of one end of the first vertical plate portion 31, a bent portion 311 bent at a substantially right angle from the first vertical plate portion 31 to the lower surface side is provided. Similarly, on the lower surface side of one end of the second vertical plate portion 32, a bent portion 321 bent at a substantially right angle from the second vertical plate portion 32 to the lower surface side is provided. As shown in FIG. 3, when the bent portion 311 of the first vertical plate portion 31 and the bent portion 321 of the second vertical plate portion 32 are viewed from the normal direction of the upper surface 2 b of the horizontal plate portion 2, They are located at the same diagonal end of contact 1. The bent portion 311 and the bent portion 321 are attached by soldering to a circuit pattern of a circuit board (not shown).

図４および図５に示すように、第１ばね部４は、伸縮方向Ｆが水平板部２の下面２ａおよび上面２ｂと交差して設けられている。第１ばね部４は、伸縮方向Ｆに平行な仮想軸Ｃの周りに巻回された板体で構成されている。第１ばね部４は板体で構成されているため、図５に示すように、第１ばね部４の巻回方向に垂直な断面の形状は長方形である。板体は、上記の断面形状である長方形の長手方向が仮想軸Ｃと平行になるように、螺旋状に巻回されている。第１ばね部４は、螺旋状に巻回された板体で構成されているため、ばねスパンを長く取ることができ、へたりにくい等のばね特性の向上を図れる。また、第１ばね部４の伸縮方向Ｆの寸法を大きく取れるため、第１ばね部４が撓んだ際に大きなばね荷重を接触部６に加えることができる。   As shown in FIGS. 4 and 5, the first spring portion 4 is provided such that the expansion and contraction direction F intersects the lower surface 2 a and the upper surface 2 b of the horizontal plate portion 2. The first spring portion 4 is formed of a plate wound around a virtual axis C parallel to the expansion and contraction direction F. Since the first spring portion 4 is formed of a plate, as shown in FIG. 5, the shape of the cross section perpendicular to the winding direction of the first spring portion 4 is rectangular. The plate is spirally wound so that the longitudinal direction of the rectangle having the above-mentioned cross-sectional shape is parallel to the imaginary axis C. Since the first spring portion 4 is formed of a spirally wound plate, the spring span can be made long, and spring characteristics such as being hard to set can be improved. Further, since the dimension of the first spring portion 4 in the expansion and contraction direction F can be increased, a large spring load can be applied to the contact portion 6 when the first spring portion 4 is bent.

第１ばね部４の下端部４ｂ（第１端部）は、第１垂直板部３１の折曲部３１１が設けられた側と反対側の側端部（ｙ方向の端部）から、水平板部２の下方の第１垂直板部３１および第２垂直板部３２が形成されていない外縁に向けて、延在して形成されている。第１垂直板部３１と第１ばね部４とは、ともに板面が仮想軸Ｃと平行になっているため、簡単な折り曲げだけで容易に形成でき、かつ、スペース効率良く配置することができる。   The lower end 4b (first end) of the first spring 4 is horizontal from the side end (end in the y direction) opposite to the side where the bent portion 311 of the first vertical plate 31 is provided. The first vertical plate portion 31 and the second vertical plate portion 32 below the plate portion 2 are formed to extend toward the outer edge not formed. Both of the first vertical plate portion 31 and the first spring portion 4 have plate surfaces parallel to the imaginary axis C, so they can be easily formed by simple bending and can be arranged with good space efficiency. .

また、第１ばね部４の中央部は水平板部２の開口部２ｈを貫通し 第１ばね部４の上端部４ｔ（第２端部）は、水平板部２の上面２ｂ側の空間に延在している。
なお、本発明において、水平板部２（第１板部）の上面２ｂ側は、水平板部２を基準として上側の空間を意味し、水平板部２（第１板部）の下面２ａ側は、水平板部２を基準として下側の空間を意味する。 Further, the central portion of the first spring portion 4 penetrates the opening 2 h of the horizontal plate portion 2, and the upper end portion 4 t (second end portion) of the first spring portion 4 is in the space on the upper surface 2 b side of the horizontal plate portion 2. It is extended.
In the present invention, the upper surface 2b side of the horizontal plate portion 2 (first plate portion) means an upper space with reference to the horizontal plate portion 2, and the lower surface 2a side of the horizontal plate portion 2 (first plate portion) Means the lower space with reference to the horizontal plate portion 2.

図３に示すように、水平板部２の上面２ｂの法線方向から見たとき、第１ばね部４は、下端部４ｂ側から上端部４ｔ側に向けて、仮想軸Ｃを略中心として反時計回りに巻回されている。第１ばね部４は、角部が曲面状に丸められた矩形状に巻回されている。   As shown in FIG. 3, when viewed in the normal direction of the upper surface 2 b of the horizontal plate portion 2, the first spring portion 4 is directed substantially from the lower end 4 b to the upper end 4 t with the virtual axis C substantially centered It is wound counterclockwise. The first spring portion 4 is wound in a rectangular shape whose corner is rounded in a curved shape.

上板部５は、第１ばね部４の上端部４ｔ（第２端部）に設けられている。図４および図５に示すように、上板部５は、平坦部５１と、曲面部５２と、を有する。平坦部５１は、上板部５の中央部に位置し、水平板部２と平行に設けられた部分である。曲面部５２は、平坦部５１の周囲のうち、第１ばね部４の上端部４ｔの折曲箇所の近傍を除く部分に設けられ、平坦部５１から下方に向けて曲面状に延びた部分である。上板部５は、第１ばね部４の弾性変形により、後述する接触部６とともに上下方向に移動可能となっている。   The upper plate portion 5 is provided at an upper end portion 4 t (second end portion) of the first spring portion 4. As shown in FIGS. 4 and 5, the upper plate portion 5 has a flat portion 51 and a curved surface portion 52. The flat portion 51 is a portion located at the central portion of the upper plate portion 5 and provided in parallel to the horizontal plate portion 2. The curved surface portion 52 is provided at a portion of the periphery of the flat portion 51 excluding the vicinity of the bent portion of the upper end portion 4 t of the first spring portion 4 and is a portion extending in a curved shape downward from the flat portion 51 is there. The upper plate portion 5 is vertically movable along with a contact portion 6 described later by elastic deformation of the first spring portion 4.

図３に示すように、接触部６は、上板部５の平坦部５１の略中央に設けられている。したがって、接触部６の位置は仮想軸Ｃの位置と概ね一致している。図４に示すように、接触部６は、上板部５の平坦部５１から上方に突出して設けられている。これにより、接触部６は、圧接コンタクト１の上方に設けられる回路基板との電気的接点として作用する。   As shown in FIG. 3, the contact portion 6 is provided substantially at the center of the flat portion 51 of the upper plate portion 5. Therefore, the position of the contact portion 6 substantially coincides with the position of the virtual axis C. As shown in FIG. 4, the contact portion 6 is provided so as to project upward from the flat portion 51 of the upper plate portion 5. Thus, the contact portion 6 acts as an electrical contact with the circuit board provided above the pressure contact 1.

第２ばね部７は、第１ばね部４と同様、伸縮方向が水平板部２の下面２ａおよび上面２ｂと交差するように設けられている。第２ばね部７は、第１ばね部４と同じ仮想軸Ｃの周りに巻回された板体で構成されている。第２ばね部７は板体で構成されており、図５に示すように、第２ばね部７の巻回方向に垂直な断面の形状は長方形である。板体は、上記の断面形状である長方形の長手方向が仮想軸Ｃと平行になるように、螺旋状に巻回されている。そのため、第２ばね部７においても、第１ばね部４と同様の理由により、ばね特性の向上が図れ、接触部６に大きなばね荷重を加えることができる。   Similar to the first spring portion 4, the second spring portion 7 is provided so that the expansion and contraction direction intersects the lower surface 2 a and the upper surface 2 b of the horizontal plate portion 2. The second spring portion 7 is formed of a plate wound around the same imaginary axis C as the first spring portion 4. The second spring portion 7 is formed of a plate, and as shown in FIG. 5, the shape of the cross section perpendicular to the winding direction of the second spring portion 7 is rectangular. The plate is spirally wound so that the longitudinal direction of the rectangle having the above-mentioned cross-sectional shape is parallel to the imaginary axis C. Therefore, also in the second spring portion 7, the spring characteristics can be improved for the same reason as the first spring portion 4, and a large spring load can be applied to the contact portion 6.

図３に示すように、第２ばね部７の下端部７ｂ（第１端部）は、第２垂直板部３２の折曲部３２１が設けられた側と反対側の側端部（−ｙ方向の端部）から、水平板部２の下方の第１垂直板部３１、第２垂直板部３２および第１ばね部４が形成されていない外縁に向けて、延在して形成されている。第１ばね部４と同様、第２垂直板部３２と第２ばね部７とは、ともに板面が仮想軸Ｃと平行になっているため、簡単な折り曲げだけで容易に形成でき、かつ、スペース効率良く配置することができる。   As shown in FIG. 3, the lower end portion 7 b (first end portion) of the second spring portion 7 is a side end portion (−y) opposite to the side where the bent portion 321 of the second vertical plate portion 32 is provided. Extending from the end of the direction toward the outer edge where the first vertical plate portion 31, the second vertical plate portion 32 and the first spring portion 4 below the horizontal plate portion 2 are not formed There is. Similar to the first spring portion 4, the second vertical plate portion 32 and the second spring portion 7 can be easily formed only by simple bending because the plate surfaces are both parallel to the imaginary axis C, and Space can be arranged efficiently.

第２ばね部７の中央部は水平板部２の開口部２ｈを貫通し 第２ばね部７の上端部７ｔ（第２端部）は、水平板部２の上面２ｂ側の空間に延在している。水平板部２の上面２ｂの法線方向から見たとき、第２ばね部７は、下端部７ｂ側から上端部７ｔ側に向けて、仮想軸Ｃを略中心として反時計回りに巻回されている。第２ばね部７は、角部が曲面状に丸められた矩形状に巻回されている。第１ばね部４の下端部４ｂと第２ばね部７の下端部７ｂとは、水平板部２の上面２ｂの法線方向から見たとき、圧接コンタクト１の同じ対角線上に位置している。   The central portion of the second spring portion 7 passes through the opening 2 h of the horizontal plate portion 2, and the upper end portion 7 t (second end portion) of the second spring portion 7 extends in the space on the upper surface 2 b side of the horizontal plate portion 2. doing. When viewed from the normal direction of the upper surface 2b of the horizontal plate portion 2, the second spring portion 7 is wound counterclockwise from the lower end 7b side to the upper end 7t side substantially about the virtual axis C. ing. The second spring portion 7 is wound in a rectangular shape whose corner is rounded in a curved shape. The lower end portion 4b of the first spring portion 4 and the lower end portion 7b of the second spring portion 7 are located on the same diagonal of the pressure contact 1 when viewed from the normal direction of the upper surface 2b of the horizontal plate portion 2. .

補助板部８は、第２ばね部７の上端部７ｔ（第２端部）に設けられている。図５に示すように、補助板部８は、平坦な板材で構成され、水平板部２と平行に設けられている。補助板部８は、上板部５と所定の間隔をおいて、平坦部５１と対向して平行に配置されている。補助板部８は、第２ばね部７の弾性変形により、上下方向に移動可能となっている。第１ばね部４と第２ばね部７とは、各々が独立したばねで構成されている。そのため、第１ばね部４と一体的に形成された上板部５と、第２ばね部７と一体的に形成された補助板部８とは、独立して移動する構成となっている。   The auxiliary plate 8 is provided at the upper end 7 t (second end) of the second spring 7. As shown in FIG. 5, the auxiliary plate portion 8 is formed of a flat plate material and is provided in parallel to the horizontal plate portion 2. The auxiliary plate portion 8 is disposed in parallel to the flat portion 51 at a predetermined distance from the upper plate portion 5. The auxiliary plate 8 is movable in the vertical direction by the elastic deformation of the second spring 7. The first spring portion 4 and the second spring portion 7 are each constituted by an independent spring. Therefore, the upper plate portion 5 integrally formed with the first spring portion 4 and the auxiliary plate portion 8 integrally formed with the second spring portion 7 are configured to move independently.

図６は、圧接コンタクト１を回路基板間に実装した状態を示す断面図である。
以下、圧接コンタクト１の使用形態の一例について図６を用いて説明する。ここでは、上下方向に並べられた２枚の回路基板の電気的接続を行う例を挙げて説明するが、使用形態はこれに限定されない。 FIG. 6 is a cross-sectional view showing a state in which the pressure contact 1 is mounted between circuit boards.
Hereinafter, an example of usage of the pressure contact 1 will be described with reference to FIG. Here, although an example in which two circuit boards arranged in the vertical direction are electrically connected will be described, the use mode is not limited to this.

圧接コンタクト１を用いて２枚の回路基板の電気的接続を行う際には、図６に示すように、第１回路基板１０１の配線パターン１０３上に圧接コンタクト１を任意の方法により接合する。ここで、第１垂直板部３１および第２垂直板部３２の下端の折曲部３１１，３１２が配線パターン１０３に半田付けされることにより、圧接コンタクト１と配線パターン１０３とが電気的に接続される。また、第２回路基板１０２を圧接コンタクト１の上方に配置し、第２回路基板１０２の配線パターン１０４を圧接コンタクト１の接触部６に当接させる。このとき、第２回路基板１０２を、２枚の回路基板１０１，１０２間の距離Ｄ１が、通常（荷重が加わっていない状態）の圧接コンタクト１の高さＴ１（図５参照）より、上板部５と補助板部８との間隔Ｓ１（図５参照）以上低くなる位置まで、圧接コンタクト１に押し付けて配置する。   When electrically connecting two circuit boards using the pressure contact 1, as shown in FIG. 6, the pressure contact 1 is joined on the wiring pattern 103 of the first circuit board 101 by an arbitrary method. Here, by bending the bent portions 311 and 312 at the lower ends of the first vertical plate portion 31 and the second vertical plate portion 32 to the wiring pattern 103, the pressure contact 1 and the wiring pattern 103 are electrically connected. Be done. Further, the second circuit board 102 is disposed above the pressure contact 1, and the wiring pattern 104 of the second circuit board 102 is brought into contact with the contact portion 6 of the pressure contact 1. At this time, the distance D1 between the two circuit boards 101 and 102 of the second circuit board 102 is the upper plate from the height T1 (see FIG. 5) of the pressure-contact 1 in a normal state (state without load applied). The pressure-contacting contact 1 is pressed and disposed to a position where it is lowered by a distance S1 (see FIG. 5) or more between the portion 5 and the auxiliary plate portion 8.

ここで、第２回路基板１０２により上板部５が押し下げられることにより、第１ばね部４が圧縮される。上板部５が間隔Ｓに相当する距離だけ押し下げられると、上板部５が補助板部８に当接する。上板部５がさらに押し下げられると、補助板部８が上板部５によって押し下げられることにより、第２ばね部７も圧縮される。よって、第１ばね部４および第２ばね部７の反力Ｈにより、上板部５が第２回路基板１０２に押し付けられる。このようにして、圧接コンタクト１と第１回路基板１０１の配線パターン１０３および第２回路基板１０２の配線パターン１０４とが電気的に安定して接続される。   Here, when the upper plate portion 5 is pushed down by the second circuit board 102, the first spring portion 4 is compressed. When the upper plate portion 5 is pushed down by a distance corresponding to the distance S, the upper plate portion 5 abuts on the auxiliary plate portion 8. When the upper plate portion 5 is further depressed, the auxiliary plate portion 8 is depressed by the upper plate portion 5 so that the second spring portion 7 is also compressed. Accordingly, the upper plate portion 5 is pressed against the second circuit board 102 by the reaction force H of the first spring portion 4 and the second spring portion 7. Thus, the pressure contact 1 and the wiring pattern 103 of the first circuit board 101 and the wiring pattern 104 of the second circuit board 102 are electrically and stably connected.

以下、本実施形態の圧接コンタクト１の効果について説明する。
圧接コンタクト１は、板面がｚ方向（伸縮方向Ｆ）に対して垂直な方向を向いた板体からなる第１ばね部４と、第１ばね部４の上端に設けられた上板部５と、を備えている。そのため、圧接コンタクト１においては、例えば板面が水平方向を向いた板体からなるばね部を備えた比較例の圧接コンタクトに比べて、水平方向の荷重に対する第１ばね部４の反力が小さく、上板部５が水平方向（ｘｙ面内の任意の方向）において変位しやすい。そのため、例えば図６の第２回路基板１０２が水平方向に振動したときに、上板部５および接触部６が第２回路基板１０２の動きに追従しやすく、接触部６と配線パターン１０４の接触点が変わらない。その結果、圧接コンタクト１と第１回路基板１０１および第２回路基板１０２との電気的接続の信頼性が確保できる、という効果を奏する。 Hereinafter, the effects of the pressure contact 1 of the present embodiment will be described.
The pressure contact 1 has a first spring portion 4 formed of a plate whose plate surface is directed in a direction perpendicular to the z direction (stretching direction F), and an upper plate portion 5 provided on the upper end of the first spring portion 4. And have. Therefore, in the pressure contact 1, for example, the reaction force of the first spring portion 4 against the load in the horizontal direction is smaller than that of the pressure contact in the comparative example provided with a spring portion consisting of a plate whose plate surface is directed horizontally. The upper plate portion 5 is easily displaced in the horizontal direction (arbitrary direction in the xy plane). Therefore, for example, when the second circuit board 102 in FIG. 6 vibrates in the horizontal direction, the upper plate portion 5 and the contact portion 6 easily follow the movement of the second circuit board 102, and the contact portion 6 and the wiring pattern 104 contact The point does not change. As a result, the reliability of the electrical connection between the pressure contact 1 and the first circuit board 101 and the second circuit board 102 can be ensured.

ところが、上板部５が水平方向に変位しやすいことで、例えば電子機器の組立工程等において、例えば、誤って作業者の指が上板部５に引っ掛かった場合、第１ばね部４に塑性変形が生じ、圧接コンタクト１の機能が低下するおそれがあった。   However, when the upper plate portion 5 is easily displaced in the horizontal direction, the plasticity of the first spring portion 4 is caused, for example, when an operator's finger is accidentally caught on the upper plate portion 5 in an assembly process of an electronic device. There is a risk that deformation may occur and the function of the pressure contact 1 may deteriorate.

上記の課題に対して、圧接コンタクト１は、下端が第１垂直板部３１と一体的に形成され、中央部が水平板部２の開口部２ｈを貫通し、上端が上方空間に延在する第１ばね部４を備えている。第１ばね部４をこのような構成としたことにより、図５に示すように、第１ばね部４を構成する板材の板面４ｄが第２水平板部２２の端面２２ｃと対向する。   In order to solve the above problems, the pressure contact 1 has a lower end integrally formed with the first vertical plate portion 31, a central portion passing through the opening 2h of the horizontal plate portion 2, and an upper end extending to the upper space A first spring portion 4 is provided. By making the 1st spring part 4 into such composition, as shown in Drawing 5, board surface 4d of the board material which constitutes the 1st spring part 4 counters end face 22c of the 2nd horizontal board part 22. As shown in FIG.

これにより、図７に示すように、例えば指Ｙが上板部５の端部に引っ掛かった場合、水平方向（図７の右から左に向く矢印Ｊの方向）の荷重を受けて上板部５が通常の位置（２点鎖線で示す）から左側に変位するとともに、第１ばね部４も通常の位置（２点鎖線で示す）から左側に変位する。このとき、ある距離以上変位が大きくなると、第１ばね部４の板面４ｄが第２水平板部２２の端面２２ｃに当接し、第１ばね部４はそれ以上変位することがない。すなわち、水平板部２は、第１ばね部４の所定距離以上の移動を規制するストッパーとして機能する。   Thus, as shown in FIG. 7, when the finger Y is caught on the end of the upper plate 5, for example, the upper plate receives a load in the horizontal direction (the direction of the arrow J from right to left in FIG. 7). While 5 is displaced to the left from the normal position (indicated by a two-dot chain line), the first spring portion 4 is also displaced to the left from the normal position (indicated by a two-dot chain line). At this time, when the displacement becomes larger than a certain distance, the plate surface 4d of the first spring portion 4 abuts on the end face 22c of the second horizontal plate portion 22, and the first spring portion 4 is not displaced further. That is, the horizontal plate portion 2 functions as a stopper that restricts the movement of the first spring portion 4 by a predetermined distance or more.

上記の課題の他の対策案として、例えば、第１ばね部４の外側にストッパーを、第１ばね部４の板面とストッパーの板面とが対向するように設ける構成も考えられる。しかしながら、この場合には、第１ばね部４からの水平方向の荷重をストッパーの板面で受けることになるため、荷重が大きくなると、ストッパーの強度が不足し、場合によっては第１ばね部４がストッパーごと塑性変形する懸念がある。これに対し、本実施形態の圧接コンタクト１の場合、第１ばね部４からの水平方向の荷重を第２水平板部２２の端面２２ｃで受けるため、荷重がある程度大きくなったとしても、第２水平板部２２は第１ばね部４の変位を十分に規制することができる。すなわち、本実施形態によれば、電気的接続の信頼性を確保しつつ、塑性変形しにくい圧接コンタクト１を実現することができる。   As another countermeasure for the above problem, for example, a configuration in which a stopper is provided on the outside of the first spring portion 4 so that the plate surface of the first spring portion 4 and the plate surface of the stopper face each other can be considered. However, in this case, since the load in the horizontal direction from the first spring portion 4 is received by the plate surface of the stopper, if the load is increased, the strength of the stopper is insufficient, and in some cases, the first spring portion 4 However, there is a concern that the stopper plastically deforms. On the other hand, in the case of the pressure-contacting contact 1 of the present embodiment, the load in the horizontal direction from the first spring portion 4 is received by the end face 22c of the second horizontal plate portion 22. The horizontal plate portion 22 can sufficiently restrict the displacement of the first spring portion 4. That is, according to the present embodiment, it is possible to realize the pressure contact 1 which is less likely to be plastically deformed while securing the reliability of the electrical connection.

さらに、圧接コンタクト１は、下端が第２垂直板部３２と一体的に形成され、中央部が水平板部２の開口部２ｈを貫通し、上端が上方空間に延在する第２ばね部７を備えている。第２ばね部７をこのような構成としたことにより、図５に示すように、第２ばね部７を構成する板材の板面７ｄが第１水平板部２１の端面２１ｃと対向する。   Furthermore, the second contact 7 has a lower end formed integrally with the second vertical plate 32, a central portion passing through the opening 2 h of the horizontal plate 2, and an upper end extending into the upper space. Is equipped. By making the 2nd spring part 7 into such composition, as shown in Drawing 5, board surface 7d of the board material which constitutes the 2nd spring part 7 counters end face 21c of the 1st horizontal board part 21. As shown in FIG.

これにより、上板部５に対して図７に示す方向Ｊと逆方向（図７の左から右）に荷重が加わったとしても、第２ばね部７の板面７ｄが第１水平板部２１の端面２１ｃに当接し、第２ばね部７はそれ以上変位することがない。そのため、図７に示す方向Ｊと逆方向の荷重に対しても塑性変形しにくい圧接コンタクト１を実現することができる。   Thus, even if a load is applied to the upper plate portion 5 in the direction (left to right in FIG. 7) opposite to the direction J shown in FIG. 7, the plate surface 7d of the second spring portion 7 is the first horizontal plate portion. It abuts on the end face 21c of 21 and the second spring portion 7 is not displaced further. Therefore, it is possible to realize the pressure-contacting contact 1 which is less likely to be plastically deformed even in the direction opposite to the direction J shown in FIG.

また、第１ばね部４および第２ばね部７の下部（水平板部２より下の部分）は、大径であるが、周囲を水平板部２と垂直板部３とに囲まれた形態となるため、第１ばね部４および第２ばね部７の下部がこれらの板部によって保護され、横方向あるいは上方向から、指等がぶつかりにくい構成となっている。この作用によっても、塑性変形しにくい圧接コンタクト１を実現することができる。さらに、水平板部２によって、図３に示す、平面視した際の最大外形から第１ばね部４あるいは第２ばね部７までの距離を確保することができる。そのため、第１ばね部４あるいは第２ばね部７に横方向から指等が当たりにくくすることができる。また、水平板部２は第１ばね部４あるいは第２ばね部７の高さ方向の略中間に位置するため、横方向から指等が当たりにくくすることができる。   In addition, although the lower portions of the first spring portion 4 and the second spring portion 7 (portions lower than the horizontal plate portion 2) have a large diameter, the form is surrounded by the horizontal plate portion 2 and the vertical plate portion 3 Therefore, the lower portions of the first spring portion 4 and the second spring portion 7 are protected by these plate portions, and a finger or the like does not easily collide in the lateral direction or the upper direction. Also by this action, it is possible to realize the pressure contact 1 which is less likely to be plastically deformed. Furthermore, the horizontal plate portion 2 can ensure the distance from the maximum outer shape in plan view shown in FIG. 3 to the first spring portion 4 or the second spring portion 7. Therefore, it is possible to make it difficult for a finger or the like to hit the first spring portion 4 or the second spring portion 7 in the lateral direction. Further, since the horizontal plate portion 2 is positioned approximately in the middle in the height direction of the first spring portion 4 or the second spring portion 7, it is possible to make it difficult for a finger or the like to hit in the lateral direction.

また、圧接コンタクト１においては、第１ばね部４の上端部４ｔに上板部５が設けられ、接触部６は上板部５の平坦部５１に設けられている。この構成によれば、例えば上板部５が設けられていない場合と比べて、接触部６の面積を確保しやすく、電気的接続の信頼性を高めることができる。   In the pressure contact 1, the upper plate 5 is provided on the upper end 4 t of the first spring 4, and the contact 6 is provided on the flat portion 51 of the upper plate 5. According to this configuration, compared to, for example, the case where the upper plate portion 5 is not provided, the area of the contact portion 6 can be easily secured, and the reliability of the electrical connection can be improved.

また、圧接コンタクト１は、第２ばね部７と、第２ばね部７の上端部７ｔに上板部５の平坦部５１と対向して設けられた補助板部８と、を備えている。この構成によれば、上板部５と補助板部８とが接触した状態において、上板部５に加わった荷重が第１ばね部４と第２ばね部７の双方に加わるため、第１ばね部４と第２ばね部７の姿勢が安定し、所定の反力を確保することができる。これにより、電気的接続の信頼性を高めることができる。   Further, the pressure contact 1 includes a second spring portion 7 and an auxiliary plate portion 8 provided on the upper end portion 7 t of the second spring portion 7 so as to face the flat portion 51 of the upper plate portion 5. According to this configuration, when the upper plate portion 5 and the auxiliary plate portion 8 are in contact with each other, the load applied to the upper plate portion 5 is applied to both the first spring portion 4 and the second spring portion 7. The postures of the spring portion 4 and the second spring portion 7 are stabilized, and a predetermined reaction force can be secured. This can enhance the reliability of the electrical connection.

また、圧接コンタクト１においては、垂直板部３が、水平板部２の両端から下方に延びる第１垂直板部３１と第２垂直板部３２とで構成されている。この構成によれば、他の支持部材等を用いることなく、圧接コンタクト１を第１回路基板１０１上に安定して支持することができる。   Further, in the pressure contact 1, the vertical plate portion 3 is configured of a first vertical plate portion 31 and a second vertical plate portion 32 extending downward from both ends of the horizontal plate portion 2. According to this configuration, the pressure contact 1 can be stably supported on the first circuit board 101 without using another support member or the like.

さらに、圧接コンタクト１においては、第１ばね部４の下端部４ｂが第１垂直板部３１と一体的に形成され、第２ばね部７の下端部７ｂが第２垂直板部３２と一体的に形成されている。この構成によれば、第１ばね部４と第２ばね部７とが干渉することなく、独立して動作することができる。これにより、合理的な二重ばね構造を有する圧接コンタクト１を実現することができる。   Furthermore, in the pressure contact 1, the lower end portion 4b of the first spring portion 4 is integrally formed with the first vertical plate portion 31, and the lower end portion 7b of the second spring portion 7 is integrally formed with the second vertical plate portion 32. Is formed. According to this configuration, the first spring portion 4 and the second spring portion 7 can operate independently without interference. Thus, the pressure contact 1 having a rational double spring structure can be realized.

なお、本発明の技術範囲は上記実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において種々の変更を加えることが可能である。
例えば上記実施形態の構成に代えて、以下の（１）〜（６）の構成を採用してもよい。 The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention.
For example, instead of the configuration of the above embodiment, the following configurations (1) to (6) may be adopted.

（１）上記実施形態では、圧接コンタクト１が第１ばね部４、第２ばね部７の２つのばね部を備えた例を示したが、本発明の圧接コンタクトは、接触部を有する第１ばね部を備えていればよく、必ずしも第２ばね部を備えていなくてもよい。また、補助板部を備えていなくてもよい。 (1) In the above-described embodiment, the pressure contact 1 includes the two spring portions of the first spring portion 4 and the second spring portion 7. However, the pressure contact of the present invention has the first portion having the contact portion. As long as the spring portion is provided, the second spring portion may not necessarily be provided. Further, the auxiliary plate may not be provided.

（２）上記実施形態では、圧接コンタクト１が上板部５を備えた例を示したが、本発明の圧接コンタクトは、上板部を備えていなくてもよい。例えば、第１ばね部の上端部に上方に突出する接触部が直接設けられていてもよい。 (2) Although the pressure contact 1 has the upper plate portion 5 in the above embodiment, the pressure contact according to the present invention may not have the upper plate portion. For example, a contact portion projecting upward may be provided directly on the upper end portion of the first spring portion.

（３）上記実施形態では、圧接コンタクト１が第１垂直板部３１、第２垂直板部３２の２つの垂直板部を備えた例を示したが、垂直板部の数は必ずしも２でなくてもよく、１〜４のいずれであってもよい。また、２つの垂直板部を備えた場合であっても、垂直板部の位置は、上記実施形態のように必ずしも水平板部の対向する２辺でなくてもよく、隣り合う２辺であってもよい。 (3) In the embodiment described above, the pressure contact 1 has the two vertical plate portions of the first vertical plate portion 31 and the second vertical plate portion 32. However, the number of vertical plate portions is not necessarily two. It may be any of 1 to 4. Further, even in the case where two vertical plate portions are provided, the position of the vertical plate portion may not necessarily be the two opposing sides of the horizontal plate portion as in the above embodiment, but two adjacent sides. May be
