Description

本発明は、２つの接触対象物の間に介在し、２つの接触対象物間の電気的な導通を図る接触端子に関するものである。   The present invention relates to a contact terminal that is interposed between two contact objects to achieve electrical conduction between the two contact objects.

従来、産業用、自動車用などの電力制御からモータ制御まで、幅広い分野に使用される省エネルギー化のキーデバイスとして、パワーモジュールが挙げられる。このパワーモジュールは、複数の半導体チップが積載された基板と、その基板上の各半導体チップにそれぞれ接触されて電力の入出力を行う複数の接触端子と、を備える。   Conventionally, a power module is a key device for energy saving used in a wide range of fields from power control to motor control for industrial use and automobile use. The power module includes a substrate on which a plurality of semiconductor chips are stacked, and a plurality of contact terminals that are in contact with each semiconductor chip on the substrate and input and output power.

接触端子においては、外部の回路基板とパワーモジュールの基板との間の確実な電気的導通が求められる。この要望に対し、弾性変形可能な接触ばねを用いて、接触対象の各基板と接触するとともに、基板間に弾性力を作用させることによって電気的に導通することが可能な接触端子が開示されている（例えば、特許文献１〜４を参照）。この接続端子によれば、接触ばねを用いることによって、導体間距離のばらつき、温度変化、基板の反り等による導体間距離変動を吸収し、２つの接触対象物間の接触状態を維持することができる。   In the contact terminal, a reliable electrical connection between the external circuit board and the power module board is required. In response to this demand, there is disclosed a contact terminal that uses an elastically deformable contact spring to come into contact with each substrate to be contacted and can be electrically connected by applying an elastic force between the substrates. (For example, see Patent Documents 1 to 4). According to this connection terminal, by using the contact spring, it is possible to absorb the variation in the distance between the conductors due to the variation in the distance between the conductors, the temperature change, the warp of the substrate, etc., and maintain the contact state between the two contact objects. it can.

さらに、屈曲した２つの梁が、端部同士で接触し、接触対象の基板から加わる荷重に応じて、この接触部分が互いに摺動することによって伸縮可能な接触端子が開示されている（例えば、特許文献５を参照）。   Further, a contact terminal is disclosed in which two bent beams are brought into contact with each other at the ends, and the contact portions can be expanded and contracted by sliding with each other in accordance with a load applied from a substrate to be contacted (for example, (See Patent Document 5).

ところで、近年、パワーモジュールを用いる電機部品は小型化および高効率化が望まれ、小型でありながら、大電流を流すことができて抵抗の発熱の少ない接触端子が求められている。特に、自動車等に搭載するパワーモジュールの接触端子の場合には、大きな電流が流れ、振動が生じた場合であっても安定して電気的導通を実現する必要がある。   Incidentally, in recent years, electrical parts using a power module are desired to be downsized and highly efficient, and there is a demand for a contact terminal that can flow a large current and generate less heat while being small. In particular, in the case of a contact terminal of a power module mounted on an automobile or the like, it is necessary to stably realize electrical conduction even when a large current flows and vibration occurs.

しかしながら、特許文献１〜４が開示する従来の接触端子では、小型化への対応のために接触端子の基板と接触する方向の距離を短くしたり、接触端子間の距離（ピッチ）を小さく（狭く）したりすると、接触端子が弾性変形するためのスペースを十分に確保することができず、端子の導体間距離変動に十分に追従できなくなるおそれがあった。また、弾性変形を確保するために接触端子の厚みを薄くすると、導通部の断面積が小さくなって、抵抗が大きくなり、抵抗による発熱量が大きくなって接触端子周囲の温度が上昇し、場合によっては、基板等が熱変形するおそれがあった。   However, in the conventional contact terminals disclosed in Patent Documents 1 to 4, the distance between the contact terminals in contact with the substrate is shortened or the distance (pitch) between the contact terminals is reduced in order to cope with downsizing ( In other words, the space for the contact terminal to be elastically deformed cannot be sufficiently secured, and there is a possibility that the variation in the distance between the conductors of the terminal cannot be sufficiently followed. If the thickness of the contact terminal is reduced to ensure elastic deformation, the cross-sectional area of the conducting part decreases, the resistance increases, the amount of heat generated by the resistance increases, and the temperature around the contact terminal increases. Depending on the case, the substrate or the like may be thermally deformed.

また、特許文献５が開示する接触端子は、弾性変形させるための領域を確保しつつ、接触端子の基板と接触する方向の距離を短くすることが可能であるものの、接触端子を伸縮させる距離に応じて摺動距離を確保しなければならず、装置の小型化には適していなかった。加えて、電流の導通経路が２つの梁を通過する経路であるために抵抗値が高く、抵抗による発熱量が大きくなって接触端子周囲の温度が上昇するおそれがあった。   Moreover, although the contact terminal which patent document 5 discloses can secure the area | region for elastically deforming and can shorten the distance of the direction which contacts the board | substrate of a contact terminal, it is the distance which expands and contracts a contact terminal. Accordingly, a sliding distance has to be ensured, which is not suitable for downsizing the apparatus. In addition, since the current conduction path is a path that passes through the two beams, the resistance value is high, and the amount of heat generated by the resistance increases, which may increase the temperature around the contact terminal.

本発明は、上記に鑑みてなされたものであって、弾性および導通性等の要求特性を維持しながら小型化を実現することができる接触端子を提供することを目的とする。   The present invention has been made in view of the above, and an object of the present invention is to provide a contact terminal that can achieve downsizing while maintaining required characteristics such as elasticity and conductivity.

第１導通部材２１は、湾曲形状をなす先端部２１ａ（第１接触部）と、各々が先端部２１ａの端部から湾曲形状に沿ってそれぞれ帯状をなして延び、弾性変形可能な複数の弾性部２１ｂ（第１弾性部）と、弾性部２１ｂの端部のうち、先端部２１ａに連なる側と異なる側の端部に設けられ、弾性部２１ｂが向かい合う方向に湾曲した弧状をなして延び、先端面が、基端で繋がっている弾性部２１ｂと向かい合う弧状部２１ｃ（第１弧状部）と、を有する。また、第１導通部材２１は、幅方向からみた側面が略Ｖ状をなし、弾性部２１ｂによって、このＶの横方向（弾性部２１ｂが向かい合う方向）に伸縮可能である。先端部２１ａは、上述した電極１０１と接触する。なお、複数の弾性部２１ｂは、上述した平面Ｓに対して連続的に拡径する斜面をなす。また、本発明において、高さ方向とはＶ字の上下方向を指す。   The first conducting member 21 has a curved tip end portion 21a (first contact portion) and a plurality of elastically deformable elastic members each extending from the end portion of the tip end portion 21a along a curved shape. Of the end portion of the portion 21b (first elastic portion) and the elastic portion 21b, it is provided at an end portion on a side different from the side continuous with the tip portion 21a, and extends in an arc shape curved in a direction in which the elastic portion 21b faces. The distal end surface has an arcuate part 21c (first arcuate part) facing the elastic part 21b connected at the base end. Further, the side surface of the first conductive member 21 viewed from the width direction is substantially V-shaped, and can be expanded and contracted in the lateral direction of V (the direction in which the elastic portion 21b faces) by the elastic portion 21b. The tip portion 21a is in contact with the electrode 101 described above. In addition, the some elastic part 21b makes the slope which expands continuously with respect to the plane S mentioned above. In the present invention, the height direction refers to the vertical direction of the V shape.

第２導通部材２２は、上述した第１導通部材２１と同一形状をなし、湾曲形状をなす先端部２２ａ（第１先端部）と、各々が先端部２２ａの端部から湾曲形状に沿ってそれぞれ帯状をなして延び、弾性変形可能な複数の弾性部２２ｂ（第２弾性部）と、弾性部２２ｂの端部のうち、先端部２２ａに連なる側と異なる側の端部に設けられ、弾性部２２ｂが向かい合う方向に弧状をなして延び、先端面が、基端で繋がっている弾性部２２ｂと向かい合う弧状部２２ｃ（第２接触部）と、を有する。また、第２導通部材２２は、幅方向からみた側面が略Ｖ状をなし、弾性部２２ｂによって、このＶの横方向（弾性部２２ｂが向かい合う方向）に伸縮可能である。各弧状部２２ｃは、上述した電極２０１とそれぞれ接触する。なお、複数の弾性部２２ｂは、上述した平面Ｓに対して連続的に拡径する斜面をなす。   The second conducting member 22 has the same shape as the first conducting member 21 described above, and has a curved distal end portion 22a (first distal end portion), each extending from the end of the distal end portion 22a along the curved shape. A plurality of elastic portions 22b (second elastic portions) that extend in a band shape and can be elastically deformed, and are provided at an end portion of the elastic portion 22b on the side different from the side continuous with the tip portion 22a. 22b extends in an arc shape in the facing direction, and the distal end surface has an arc-shaped portion 22c (second contact portion) facing the elastic portion 22b connected at the base end. The side surface of the second conductive member 22 viewed from the width direction is substantially V-shaped, and can be expanded and contracted in the lateral direction of V (the direction in which the elastic portion 22b faces) by the elastic portion 22b. Each arcuate portion 22c is in contact with the electrode 201 described above. In addition, the some elastic part 22b makes the slope which expands continuously with respect to the plane S mentioned above.

接触端子２は、第１導通部材２１と第２導通部材２２とが、弾性部２１ｂ，２２ｂの板面が揃うようにＶ字の上下方向に重ねられ、弧状部２１ｃが弾性部２２ｂに接触することで連結している。このとき、先端部２１ａおよび／または弧状部２２ｃから荷重が加わった場合に、弧状部２１ｃが弾性部２２ｂに対して摺動することで、各弾性部２１ｂ間の距離（ギャップ）が、弾性部２２ｂに沿って拡大して第２導通部材２２を第１導通部材２１のＶ字の内部空間に収容する。これにより、接触端子２は、先端部２１ａおよび先端部２２ａを通過する軸線方向に伸縮可能となる。具体的には、第１導通部材２１における先端部２１ａおよび先端部２２ａを通過する軸線方向の弾性変形と、この軸線方向に直交する方向（ピッチ方向）の弾性変形とを、第２導通部材２２の弾性部２２ｂの傾斜によって接触端子２の軸線方向の弾性変形、すなわち撓みに変換することが可能となる。   In the contact terminal 2, the first conducting member 21 and the second conducting member 22 are overlapped in the vertical direction of the V shape so that the plate surfaces of the elastic portions 21b and 22b are aligned, and the arc-shaped portion 21c contacts the elastic portion 22b. Are connected. At this time, when a load is applied from the distal end portion 21a and / or the arc-shaped portion 22c, the arc-shaped portion 21c slides with respect to the elastic portion 22b, so that the distance (gap) between the elastic portions 21b becomes the elastic portion. The second conducting member 22 is accommodated in a V-shaped internal space of the first conducting member 21 by expanding along 22 b. Thereby, the contact terminal 2 can be expanded and contracted in the axial direction passing through the distal end portion 21a and the distal end portion 22a. Specifically, the elastic deformation in the axial direction passing through the distal end portion 21a and the distal end portion 22a in the first conductive member 21 and the elastic deformation in the direction (pitch direction) orthogonal to the axial direction are defined as the second conductive member 22. By the inclination of the elastic portion 22b, it is possible to convert the contact terminal 2 into elastic deformation in the axial direction, that is, bending.

接触端子ホルダ３は、樹脂やマシナブルセラミックなどの絶縁性材料を用いて形成され、略板状をなし、接触端子２を所定パターンで保持するためのホルダ孔３１を有する。ホルダ孔３１は、段付き形状をなす断面を有する空間であって、配設する接触端子２に対応して設けられ、接触端子２の端部が接触端子ホルダ３の上面から突出するように接触端子２を内部で保持する。   The contact terminal holder 3 is formed using an insulating material such as resin or machinable ceramic, has a substantially plate shape, and has a holder hole 31 for holding the contact terminal 2 in a predetermined pattern. The holder hole 31 is a space having a stepped cross section, is provided corresponding to the contact terminal 2 to be disposed, and contacts so that the end of the contact terminal 2 protrudes from the upper surface of the contact terminal holder 3. The terminal 2 is held inside.

すなわち、ホルダ孔３１は、接触端子ホルダ３の板厚方向に貫通している。ホルダ孔３１は、接触端子ホルダ３の下端面に開口を有する第１大径部３１ａと、第１大径部３１ａの連結部において、第１大径部３１ａより小さい径であって、この第１大径部３１ａ側から拡径する孔をなす拡径部３１ｂと、拡径部３１ｂに連なり、この拡径部３１ｂに連なる側の径と同等の径で柱状に延びる孔をなす孔部３１ｃと、孔部３１ｃと連結し、第１大径部３１ａの径と略同等の径であって、接触端子ホルダ３の上端面に開口を有する第２大径部３１ｄと、からなる（図３，４参照）。第１大径部３１ａ、拡径部３１ｂおよび第２大径部３１ｄは、互いの軸線（中心線）が一致するように形成されている。なお、第１大径部３１ａおよび第２大径部３１ｄは、それぞれ収容する電極の大きさに応じて形成される。   That is, the holder hole 31 penetrates in the plate thickness direction of the contact terminal holder 3. The holder hole 31 is smaller in diameter than the first large diameter portion 31a in the connecting portion between the first large diameter portion 31a having an opening on the lower end surface of the contact terminal holder 3 and the first large diameter portion 31a. A diameter-enlarging portion 31b that forms a hole that expands from the one large-diameter portion 31a side, and a hole portion 31c that forms a hole extending in a columnar shape with a diameter that is the same as the diameter on the side connected to the diameter-expanding portion 31b. And a second large-diameter portion 31d connected to the hole portion 31c and having a diameter substantially equal to the diameter of the first large-diameter portion 31a and having an opening on the upper end surface of the contact terminal holder 3 (FIG. 3). , 4). The 1st large diameter part 31a, the enlarged diameter part 31b, and the 2nd large diameter part 31d are formed so that a mutual axis line (center line) may correspond. The first large-diameter portion 31a and the second large-diameter portion 31d are formed according to the size of the accommodated electrode.

また、拡径部３１ｂの収縮している側の径は、先端部２１ａの径より大きい。また、孔部３１ｃの径は、第２導通部材２２の弧状部２２ｃの各外縁を結ぶ径より大きい。   Moreover, the diameter of the contracted side of the enlarged diameter portion 31b is larger than the diameter of the distal end portion 21a. Further, the diameter of the hole 31 c is larger than the diameter connecting the outer edges of the arc-shaped portion 22 c of the second conducting member 22.

本実施の形態１にかかる接触端子ユニット１は、第１導通部材２１の弾性部２１ｂが拡径部３１ｂに当接することで接触端子ホルダ３からの抜止機能を有する。また、接触端子ユニット１が基板１００上に載置されることで、電極１０１の上面と先端部２１ａとが当接し、弧状部２２ｃが接触端子ホルダ３の上面から突出する。   The contact terminal unit 1 according to the first embodiment has a function of preventing the contact terminal holder 3 from being removed by the elastic portion 21b of the first conducting member 21 coming into contact with the enlarged diameter portion 31b. Further, since the contact terminal unit 1 is placed on the substrate 100, the upper surface of the electrode 101 and the tip portion 21 a come into contact with each other, and the arc-shaped portion 22 c protrudes from the upper surface of the contact terminal holder 3.

図５は、本実施の形態１にかかる接触端子２および接触端子ホルダ３の構成であり、基板実装前後の状態を模式的に示す部分断面図であって、先端部２１ａまたは弧状部２２ｃに荷重が加わる前後の状態を示す部分断面図である。図５に示すように、先端部２１ａが基板１００の電極１０１と接触した状態で、弧状部２２ｃに対して基板２００から荷重が加わると、第２導通部材２２からの押圧によって弾性部２１ｂが弾性変形することで、各弾性部２１ｂ間の径が、弾性部２２ｂ間の径に沿って拡径する。このとき、弧状部２１ｃが弾性部２２ｂの板面に対して摺接しながら第２導通部材２２を第１導通部材２１のＶ字の内部空間に収容する。これにより、接触端子２は、第２接触部２２ａおよび第１接触部２１ｂを通過する軸線方向に縮小する。ここで、破線Ｐ０は、基板２００から荷重が加わっていない状態での接触端子２の位置を示している（図３参照）。なお、各導通部材（第１導通部材２１および第２導通部材２２）において、このときに流れる電流は、先端部２１ａから各弾性部２１ｂ，２２ｂを介して弧状部２１ｃ，２２ｃを結ぶ経路の両方の経路に流れる。導通部材は複数の経路により電流を流すため、大きな導通断面積を確保することができ、多くの電流を流すことが可能となる。FIG. 5 is a configuration of the contact terminal 2 and the contact terminal holder 3 according to the first embodiment, and is a partial cross-sectional view schematically showing the state before and after mounting on the substrate, with the load applied to the tip portion 21a or the arc-shaped portion 22c. It is a fragmentary sectional view which shows the state before and behind adding. As shown in FIG. 5, when a load is applied from the substrate 200 to the arcuate portion 22 c in a state where the tip portion 21 a is in contact with the electrode 101 of the substrate 100, the elastic portion 21 b is elastic due to the pressing from the second conductive member 22. By deforming, the diameter between the elastic portions 21b expands along the diameter between the elastic portions 22b. At this time, the second conductive member 22 is accommodated in the V-shaped internal space of the first conductive member 21 while the arc-shaped portion 21 c is in sliding contact with the plate surface of the elastic portion 22 b. Thereby, the contact terminal 2 contracts in the axial direction passing through the second contact portion 22a and the first contact portion 21b. Here, the broken line P 0 indicates the position of the contact terminal 2 in a state where no load is applied from the substrate 200 (see FIG. 3). In each conducting member (the first conducting member 21 and the second conducting member 22), the current flowing at this time is both on the path connecting the arcuate portions 21c and 22c from the distal end portion 21a via the elastic portions 21b and 22b. Flowing in the path. Since the conducting member allows current to flow through a plurality of paths, a large conducting cross-sectional area can be ensured and a large amount of current can be passed.

また、接触端子２は、基板２００から荷重を受け、先端部２１ａおよび先端部２２ａを通過する軸線方向に縮小している際、弾性部２１ｂが元の形状に戻ろうとする力を加えるため、軸線方向に縮小する一方で、先端部２１ａと先端部２２ａとが離れる方向に荷重が加わる。すなわち、接触端子２は、軸線方向に縮小する一方で、先端部２１ａおよび先端部２２ａがそれぞれ基板２００，１００側に荷重を加えた状態（基板に対して付勢した状態）となっている。この付勢状態により、振動が生じて、基板１００，２００間の距離が変化した場合であっても接触端子２は、その変化に追従して基板間の導通状態を維持する。   Further, when the contact terminal 2 receives a load from the substrate 200 and contracts in the axial direction passing through the tip portion 21a and the tip portion 22a, the contact terminal 2 applies a force to return the elastic portion 21b to the original shape. While shrinking in the direction, a load is applied in a direction in which the tip 21a and the tip 22a are separated. That is, the contact terminal 2 is contracted in the axial direction, while the distal end portion 21a and the distal end portion 22a are in a state in which a load is applied to the substrate 200, 100 side (a state in which the contact terminal 2 is urged against the substrate). Even if the vibration is generated by this biased state and the distance between the substrates 100 and 200 is changed, the contact terminal 2 follows the change and maintains the conductive state between the substrates.

このとき、対向する２つの弾性部２１ｂ（２２ｂ）の板面がなす角度θは、ｔａｎ（θ／２）≧μとなる関係を満たす（図６参照）。ここで、μは、弾性部２１ｂ（２２ｂ）および弧状部２１ｃ（２２ｃ）の接触部分における摩擦係数である。例えば、接触端子２として銅系材料を用いて形成され、その摩擦係数μがμ＝０．２である場合、角度θは、ｔａｎ（θ／２）≧０．２から、θ≧２２．８°（θ／２≧１１．４°）を満たす数値となる。   At this time, the angle θ formed by the plate surfaces of the two opposing elastic portions 21b (22b) satisfies the relationship of tan (θ / 2) ≧ μ (see FIG. 6). Here, μ is a friction coefficient at the contact portion of the elastic portion 21b (22b) and the arc-shaped portion 21c (22c). For example, when the contact terminal 2 is formed using a copper-based material and the friction coefficient μ is μ = 0.2, the angle θ is from tan (θ / 2) ≧ 0.2 to θ ≧ 22.8. It is a numerical value satisfying ° (θ / 2 ≧ 11.4 °).

なお、θ≦２２．８の場合、弾性部２２ｂが元の形状に戻ろうとする際に弧状部２１ｃが弾性部２２ｂに対して加える荷重が、弧状部２１ｃと弾性部２２ｂとの間の摩擦力より小さくなる。これにより、第２導通部材２２の弾性部２２ｂが、第１導通部材２１の弧状部２１ｃの間で固定された状態となり、基板（電極）側に対して付勢した状態を維持できなくなる。その結果、振動等による基板の動きに追従できなくなるおそれがあるため、θは、３０°以上（１８０°未満）であることが好ましい。   When θ ≦ 22.8, the load applied by the arc-shaped portion 21c to the elastic portion 22b when the elastic portion 22b attempts to return to the original shape is a frictional force between the arc-shaped portion 21c and the elastic portion 22b. Smaller. Thereby, the elastic part 22b of the 2nd conduction member 22 will be in the state fixed between the arc-shaped parts 21c of the 1st conduction member 21, and it will become impossible to maintain the state urged | biased with respect to the board | substrate (electrode) side. As a result, θ may not be able to follow the movement of the substrate due to vibration or the like, and therefore θ is preferably 30 ° or more (less than 180 °).

本実施の形態によれば、導電性の部材を用いて形成される接触端子２が、第２導通部材２２を第１導通部材２１の内部空間に収容することによって先端部２１ａおよび先端部２２ａを通過する軸線方向に伸縮するようにしたので、弾性および導通性等の要求特性を維持しながら小型化を実現することができる。   According to the present embodiment, the contact terminal 2 formed using a conductive member accommodates the second conducting member 22 in the internal space of the first conducting member 21, so that the distal end portion 21 a and the distal end portion 22 a are accommodated. Since it extends and contracts in the direction of the passing axis line, it is possible to achieve downsizing while maintaining required characteristics such as elasticity and conductivity.

第１導通部材２１および第２導通部材２２は、帯状の部材を用いて形成されているため、板面に直交する方向の断面積を大きく取ることができる。また、先端部２１ａ（２２ａ）の湾曲に沿って複数の弾性部２１ｂ（２２ｂ）が設けられており、導通経路が２方向となるため、通電用の断面積を一段と大きく取ることが可能となる。これにより、導体抵抗が小さくなり、大電流を流すことができるとともに、抵抗による発熱量を小さくすることができる。   Since the 1st conduction member 21 and the 2nd conduction member 22 are formed using a belt-shaped member, the cross-sectional area of the direction orthogonal to a plate surface can be taken large. Moreover, since the some elastic part 21b (22b) is provided along the curve of the front-end | tip part 21a (22a) and a conduction path becomes 2 directions, it becomes possible to take the cross-sectional area for electricity supply much larger. . As a result, the conductor resistance is reduced, a large current can flow, and the amount of heat generated by the resistance can be reduced.

また、第１導通部材２１および第２導通部材２２は、弧状部２１ｃと弾性部２２ｂとが摺接することで接触し、連結している。このとき、弾性部２２ｂは、弧状部２１ｃに対してくさび状に入り込んだ状態で接触している。このくさび状に連結した状態によって、平面同士を突き当てて接触した接触状態と比して、接触抵抗を小さくすることができる。   Moreover, the 1st conduction | electrical_connection member 21 and the 2nd conduction | electrical_connection member 22 contact and are connected because the arc-shaped part 21c and the elastic part 22b contact. At this time, the elastic portion 22b is in contact with the arc-shaped portion 21c in a wedge shape. The contact resistance can be reduced by the state of being connected in a wedge shape as compared with the contact state in which the flat surfaces are brought into contact with each other.

なお、第１導通部材２１および第２導通部材２２の各弾性部２１ｂ，２２ｂは、第１導通部材２１および第２導通部材２２の接触導通が確保できれば、各先端部２１ａ，２２ａから湾曲形状に沿って延びる弾性部２１ｂ，２２ｂの形状が互いに同じ形状であってもよいし、異なる形状（例えば、板厚が異なる、先端部から延びる長さが異なる）であってもよい。なお、湾曲形状に沿って延びる形状が互いに同じ形状とは、第１導通部材２１と第２導通部材２２とが連結した状態において、先端部２１ａおよび先端部２２ａを通過する軸線に対して対称な形状である。また、同じ形状とは、設計上同一の形状をなすものであり、製造上の誤差を含む。   In addition, each elastic part 21b, 22b of the 1st conduction member 21 and the 2nd conduction member 22 will be curved from each front-end | tip part 21a, 22a, if the contact conduction of the 1st conduction member 21 and the 2nd conduction member 22 can be ensured. The elastic portions 21b and 22b extending along the same shape may be the same shape or different shapes (for example, different plate thicknesses and different lengths extending from the tip portion). Note that the shapes extending along the curved shape are the same as each other when the first conducting member 21 and the second conducting member 22 are connected to each other with respect to the axis passing through the tip portion 21a and the tip portion 22a. Shape. Further, the same shape means the same shape in design and includes manufacturing errors.

また、第１導通部材２１および第２導通部材２２は、帯状をなすものとして説明したが、その幅は同等であってもよいし、異なっていてもよい。なお、例えば第１接触部において、幅を小さくして、接触面積を小さくすることによって抵抗値を低下させることができるため好ましく、成形性を向上させることも可能となる。ここで、第１導通部材２１（第２導通部材２２）の各弾性部２１ｂ（２２ｂ）は、各弾性部２１ｂ（２２ｂ）に流れる電流を安定させるために、同一の断面積であることが好ましい。断面積の調節は、幅方向および板厚方向の長さを適宜調整することで対応可能である。   Moreover, although the 1st conduction | electrical_connection member 21 and the 2nd conduction | electrical_connection member 22 were demonstrated as what makes a strip | belt shape, the width | variety may be equivalent and may differ. For example, in the first contact portion, the resistance value can be reduced by reducing the width and reducing the contact area, and it is possible to improve the moldability. Here, each elastic part 21b (22b) of the first conductive member 21 (second conductive member 22) preferably has the same cross-sectional area in order to stabilize the current flowing through each elastic part 21b (22b). . The cross-sectional area can be adjusted by appropriately adjusting the lengths in the width direction and the plate thickness direction.

また、第１導通部材２１（第２導通部材２２）の各弾性部２１ｂ（２２ｂ）が、先端部２１ａ（２２ａ）から湾曲形状に沿って延びる形状が同じ形状である場合、各弾性部２１ｂ（２２ｂ）の抵抗が等しく、各弾性部２１ｂ（２２ｂ）に流れる電流も等しくなるため、より多くの電流を流すことが可能となる。また、各弾性部２１ｂ（２２ｂ）が同じ形状であれば、第１導通部材２１（第２導通部材２２）の伸縮動作が円滑になり、接触端子２の一層安定した伸縮動作を得ることが可能となる。   Moreover, when each elastic part 21b (22b) of the 1st conduction | electrical_connection member 21 (2nd conduction | electrical_connection member 22) is the same shape extended along a curve shape from the front-end | tip part 21a (22a), each elastic part 21b ( Since the resistance of 22b) is equal and the current flowing through each elastic portion 21b (22b) is also equal, more current can be passed. Moreover, if each elastic part 21b (22b) is the same shape, the expansion-contraction operation | movement of the 1st conduction | electrical_connection member 21 (2nd conduction | electrical_connection member 22) will become smooth, and it can obtain the more stable expansion-contraction operation | movement of the contact terminal 2. It becomes.

図７は、本実施の形態の変形例１にかかる接触端子の構成を模式的に示す模式図である。変形例１においても、接触端子２ａが、長手方向の両端で電極１０１および基板２００の電極２０１とそれぞれ接触することによって電極１０１と電極２０１との間を電気的に導通させる。接触端子２ａは、導電性部材を用いて形成され、電極１０１と接触する第１導通部材２３と、第１導通部材２３と接触して連結し、電極２０１と接触する第２導通部材２４と、を有する。接触端子２ａは、例えば純銅または、ばね性を有する銅系材料等を用いて形成される。   FIG. 7 is a schematic diagram schematically showing the configuration of the contact terminal according to the first modification of the present embodiment. Also in the modified example 1, the contact terminal 2a is electrically connected between the electrode 101 and the electrode 201 by contacting the electrode 101 and the electrode 201 of the substrate 200 at both ends in the longitudinal direction. The contact terminal 2a is formed using a conductive member, a first conductive member 23 that contacts the electrode 101, a second conductive member 24 that contacts and is connected to the first conductive member 23, and contacts the electrode 201; Have The contact terminal 2a is formed using, for example, pure copper or a copper-based material having spring properties.

第１導通部材２３は、凸状の湾曲形状をなし、この凸の先端で上述した電極１０１と接触する先端部２３ａ（第１接触部）と、各々が先端部２３ａの端部から湾曲形状に沿ってそれぞれ帯状をなして延び、弾性変形可能な複数の弾性部２３ｂ（第１弾性部）と、弾性部２３ｂの端部のうち、先端部２３ａに連なる側と異なる側の端部に設けられ、弾性部２３ｂが向かい合う方向と反対方向に湾曲し、弧状をなして延びる弧状部２３ｃ（第１弧状部）と、を有する。また、第１導通部材２３は、幅方向からみた側面が略Ｖ字状をなし、弾性部２３ｂによって、このＶの横方向（弾性部２３ｂが向かい合う方向）に伸縮可能である。   The first conducting member 23 has a convex curved shape, and the distal end portion 23a (first contact portion) that contacts the above-described electrode 101 at the convex distal end, and each of the first conductive member 23 is curved from the end portion of the distal end portion 23a. A plurality of elastic portions 23b (first elastic portions) that extend in a belt shape and can be elastically deformed, and the end portions of the elastic portions 23b are provided at end portions that are different from the side that is continuous with the tip portion 23a. And an arcuate part 23c (first arcuate part) that curves in a direction opposite to the direction in which the elastic part 23b faces and extends in an arc shape. Further, the side surface of the first conductive member 23 viewed from the width direction is substantially V-shaped, and can be expanded and contracted in the lateral direction of V (the direction in which the elastic portion 23b faces) by the elastic portion 23b.
