Description

圧接端子Pressure contact terminal
　本発明は、例えば、基板と基板との間に圧縮状態で配置される圧接端子に関する。 The present invention relates to, for example, a pressure contact terminal arranged in a compressed state between a substrate and a substrate.
　従来、部材間に配置される圧接端子として、例えば、導電性の金属板を打ち抜き、更に折り曲げ加工をして形成されたアースターミナルがある（特許文献１参照）。 Conventionally, as a pressure contact terminal disposed between members, for example, there is an earth terminal formed by punching a conductive metal plate and further bending it (see Patent Document 1).
　前記アースターミナルは、板状体からなり、底面がプリント回路基板ＰＣＢに取付けられる取付部を形成するベース部２と、ベース部２の対向する両辺からそれぞれ上方へ延設され、中間部には係止孔３１が穿設されるストッパ受け部３と、ベース部２の他の一辺からベース部２上面と対向する側に延設され、延設部分から弾性変形可能な接触部４と、接触部４の対向する両辺からベース部２側にそれぞれ延設され、先端部はストッパ受け部３の係止孔３１と係止される係止部５１を形成し、係止孔３１との係止により上方への移動が規制されるストッパ５とから成る。 The ground terminal is formed of a plate-like body, and the bottom surface is extended upward from both opposing sides of the base portion 2 and the base portion 2 forming a mounting portion to be attached to the printed circuit board PCB, and the intermediate portion is connected to the intermediate portion. A stopper receiving portion 3 in which a stop hole 31 is formed, a contact portion 4 extending from the other side of the base portion 2 to the side facing the upper surface of the base portion 2 and elastically deformable from the extended portion, and a contact portion 4 is extended from both opposing sides to the base part 2 side, and the tip part forms a locking part 51 to be locked with the locking hole 31 of the stopper receiving part 3. The stopper 5 is restricted from moving upward.
特開２００３－６９２５０号公報JP 2003-69250 A
　しかし、前記アースターミナルは、その図１に示すように、ベース部２の湾曲部４１に直線部４２を介して平行部４３が片持ち支持されているだけであるので、前記湾曲部４１に応力が集中して破損し易く、耐久性に乏しいという問題がある。また、ストッパ受け部３とストッパ５とを設けるので、製造コストが増加するという問題がある。 However, in the ground terminal, as shown in FIG. 1, the parallel portion 43 is simply cantilevered via the straight portion 42 on the curved portion 41 of the base portion 2. However, there is a problem that it is easy to break due to concentration and poor durability. Moreover, since the stopper receiving part 3 and the stopper 5 are provided, there exists a problem that manufacturing cost increases.
　本発明は前記従来の問題点に鑑みてなされたもので、製造コストを削減すると共に、応力の集中を防止して耐久性を高め、寿命の長い圧接端子を提供することを課題とする。 The present invention has been made in view of the above-mentioned conventional problems, and it is an object of the present invention to provide a press contact terminal that reduces manufacturing costs, prevents stress concentration, improves durability, and has a long life.
　本発明は、
　第１部材と第２部材との間に挟持される圧接端子であって、
　前記第１部材に固定される支持部と、
　前記支持部の一端から、前記支持部に沿って離間する方向に延びる弾性腕部と、
　前記弾性腕部の先端部に設けられ、前記第２部材に圧接する圧接部と、
　を備えた。 The present invention
A press contact terminal sandwiched between the first member and the second member,
A support portion fixed to the first member;
An elastic arm portion extending from one end of the support portion in a direction away from the support portion;
A pressure contact portion provided at a distal end portion of the elastic arm portion and in pressure contact with the second member;
Equipped with.
　支持部と弾性腕部と圧接部のみから圧接端子を構成するので、圧接端子の構成を簡単にし、製造コストを削減できる。 Since the press contact terminal is composed only of the support portion, the elastic arm portion, and the press contact portion, the configuration of the press contact terminal can be simplified and the manufacturing cost can be reduced.
　前記弾性腕部は、
　前記支持部から延在する第１腕部と、
　前記第１腕部の一端から鈍角を形成するように、前記支持部から離間する方向に延在する第２腕部と、
　を備えることが好ましい。 The elastic arm is
A first arm portion extending from the support portion;
A second arm portion extending in a direction away from the support portion so as to form an obtuse angle from one end of the first arm portion;
It is preferable to provide.
　圧接部を支持部に向かって押圧すると、まず第１腕部が弾性変形し、第１腕部の端部が支持部に向かって変位する。そして第１腕部の端部が支持部に当接すると、第２腕部が弾性変形し、圧接部が支持部に向かって変位する。このように弾性腕部が２段階で弾性変形することで、弾性腕部の一部への応力の集中を防止して耐久性を高め、寿命を長くできる。 When the pressure contact portion is pressed toward the support portion, the first arm portion is first elastically deformed, and the end portion of the first arm portion is displaced toward the support portion. When the end portion of the first arm portion comes into contact with the support portion, the second arm portion is elastically deformed, and the press contact portion is displaced toward the support portion. By elastically deforming the elastic arm portion in two stages in this way, stress concentration on a part of the elastic arm portion can be prevented, durability can be improved, and the life can be extended.
　前記支持部の両端部から一対の前記弾性腕部が、内方に向かってそれぞれ延び、
　前記弾性腕部の先端に位置する一対の前記圧接部が、所定の間隔を隔てて対向することが好ましい。 A pair of the elastic arm portions respectively extend inward from both ends of the support portion,
It is preferable that a pair of said press-contact part located in the front-end | tip of the said elastic arm part opposes at predetermined intervals.
　弾性腕部を一対設けることで、一方の弾性腕部への応力の集中を防止して耐久性を高め、寿命を長くできる。 By providing a pair of elastic arm portions, stress concentration on one elastic arm portion can be prevented, durability can be improved, and life can be extended.
　前記弾性腕部が前記支持部の一端から延在する一方、
　前記支持部の他端から延在する補助腕部の先端部が、対向する前記支持部と前記圧接部との間に位置することが好ましい。 While the elastic arm portion extends from one end of the support portion,
It is preferable that a distal end portion of an auxiliary arm portion extending from the other end of the support portion is located between the support portion and the pressure contact portion facing each other.
　圧接部を押圧すると、支持部に向かって弾性変形する弾性腕部がまず、補助腕部と当接する。更に圧接部を押圧すると、弾性腕部と補助腕部とが一体となって上下方向に圧縮されるように弾性変形する。これにより、応力が弾性腕部と補助腕部とに分散され、弾性腕部のみへの応力の集中を防止して耐久性を高め、寿命を長くできる。 When the pressure contact portion is pressed, the elastic arm portion that is elastically deformed toward the support portion first comes into contact with the auxiliary arm portion. When the pressure contact portion is further pressed, the elastic arm portion and the auxiliary arm portion are integrally deformed so as to be compressed in the vertical direction. As a result, the stress is distributed to the elastic arm portion and the auxiliary arm portion, and concentration of the stress only on the elastic arm portion is prevented, thereby improving durability and extending the life.
　前記支持部、前記弾性腕部および前記圧接部のうち、少なくともいずれか１つの少なくとも一部の断面積を、アスペクト比２以上とすることが好ましい。
　アスペクト比を２以上とすることで、弾性変形しやすい圧接端子を得ることができる。 It is preferable that at least a part of at least one of the support portion, the elastic arm portion, and the pressure contact portion has an aspect ratio of 2 or more.
By setting the aspect ratio to 2 or more, a press contact terminal that is easily elastically deformed can be obtained.
　電鋳法により形成し、前記弾性腕部の厚みに対して、前記弾性腕部の幅を大きくすることが好ましい。
　これにより、圧接部を支持部に向かって押圧したときに、弾性腕部に捩れが生じることなく、安定した弾性変形を得ることが可能になる。 Preferably, the elastic arm portion is formed by electroforming, and the width of the elastic arm portion is increased with respect to the thickness of the elastic arm portion.
As a result, when the pressure contact portion is pressed toward the support portion, it is possible to obtain a stable elastic deformation without twisting the elastic arm portion.
　電鋳法により形成し、前記弾性腕部を電鋳法による電圧印加方向と垂直な方向に弾性変形可能とすることが好ましい。

　以下、本発明に係る圧接端子の実施形態を添付図面の図１ないし図１１に従って説明する。 Hereinafter, an embodiment of a pressure contact terminal according to the present invention will be described with reference to FIGS. 1 to 11 of the accompanying drawings.
　（第１実施形態）
　第１実施形態の圧接端子１０は、図１および図２に示すように、金属からなる幅狭の板状体で形成されている。圧接端子１０は、その断面積をアスペクト比２以上、好ましくは３以上としているので弾性変形しやすくなる。圧接端子１０は、支持部１１と弾性腕部１３と圧接部１２とを備え、第１部材１と第２部材２との間に挟持される。 (First embodiment)
As shown in FIGS. 1 and 2, the press contact terminal 10 of the first embodiment is formed of a narrow plate-like body made of metal. Since the cross-sectional area of the press contact terminal 10 is 2 or more, preferably 3 or more, it is easily elastically deformed. The press contact terminal 10 includes a support portion 11, an elastic arm portion 13, and a press contact portion 12, and is sandwiched between the first member 1 and the second member 2.
　支持部１１は圧接端子１０の下端部に設けられた長板状であり、第１部材である基板１に半田付して固定される。 The support portion 11 is a long plate provided at the lower end portion of the press contact terminal 10 and is fixed to the substrate 1 as the first member by soldering.
　図３に示すように、弾性腕部１３は、支持部１１の端部から支持部１１に沿って離間する方向に延び、先端部の圧接部１２を支持部１１から離間するように上方向に付勢する。弾性腕部１３は、支持部１１側の第１腕部１４と圧接部１２側の第２腕部１７とを備え、圧接部１２を片持ち支持している。 As shown in FIG. 3, the elastic arm portion 13 extends from the end portion of the support portion 11 in a direction away from the support portion 11, and upwards so that the press contact portion 12 at the distal end portion is separated from the support portion 11. Energize. The elastic arm portion 13 includes a first arm portion 14 on the support portion 11 side and a second arm portion 17 on the pressure contact portion 12 side, and supports the pressure contact portion 12 in a cantilever manner.
　第１腕部１４は、支持部１１の端部から延在し、側方に向かって凸状となる横向きＵ字形状の第１屈曲部１５と、第１屈曲部１５の上側端部から支持部１１に沿って平行に延びる第１延在部１６とを有している。 The first arm portion 14 extends from the end portion of the support portion 11 and is supported from the laterally U-shaped first bent portion 15 that is convex toward the side and the upper end portion of the first bent portion 15. And a first extending portion 16 extending in parallel along the portion 11.
　第２腕部１７は、圧接部１２と第１腕部１４との間に配置されている。そして、第２腕部１７は第１腕部１４に対して鈍角をなす第２屈曲部１８と、第２屈曲部１８から斜め上方に直線状に延びる第２延在部１９とを有している。 The second arm portion 17 is disposed between the press contact portion 12 and the first arm portion 14. The second arm portion 17 has a second bent portion 18 that forms an obtuse angle with respect to the first arm portion 14, and a second extending portion 19 that extends linearly obliquely upward from the second bent portion 18. Yes.
　圧接部１２は弾性腕部１３の先端部に設けられ、支持部１１の端部の上方に配置されている。圧接部１２は、上方に向かって凸状となるように湾曲し、正方形状の基板（第２部材）２に圧接する。 The pressure contact portion 12 is provided at the distal end portion of the elastic arm portion 13 and is disposed above the end portion of the support portion 11. The pressure contact portion 12 is curved so as to be convex upward, and is in pressure contact with the square substrate (second member) 2.
　以上のように、支持部１１、圧接部１２および弾性腕部１３から圧接端子１０を構成するので、圧接端子１０の構成が簡単であり、製造コストを削減できる。 As described above, since the press contact terminal 10 is constituted by the support portion 11, the press contact portion 12, and the elastic arm portion 13, the configuration of the press contact terminal 10 is simple, and the manufacturing cost can be reduced.
　支持部１１の第１屈曲部１５側の端部には、圧接端子１０を基板２に取り付ける際に、治具に保持される取付保持部１０ａが連設されている。支持部１１と取付保持部１０ａとの間には、板厚の薄い薄肉部１０ｂが形成されている。 At the end of the support portion 11 on the first bent portion 15 side, an attachment holding portion 10a that is held by a jig when the press contact terminal 10 is attached to the substrate 2 is continuously provided. A thin portion 10b having a small plate thickness is formed between the support portion 11 and the attachment holding portion 10a.
　図４に示すように、圧接部１２を支持部１１に向かって下方に押圧すると、まず第１腕部１４が弾性変形し、第２屈曲部１８が支持部１１に向かって変位する。そして、図５に示すように、第２屈曲部１８が支持部１１に当接すると、第２腕部１７が弾性変形し、圧接部１２が支持部１１に向かって変位する。このように弾性腕部１３が２段階で弾性変形することにより、弾性腕部１３への応力の集中を防止でき、耐久性を高め、寿命を長くできる。 As shown in FIG. 4, when the pressure contact portion 12 is pressed downward toward the support portion 11, the first arm portion 14 is first elastically deformed, and the second bent portion 18 is displaced toward the support portion 11. Then, as shown in FIG. 5, when the second bent portion 18 comes into contact with the support portion 11, the second arm portion 17 is elastically deformed, and the press contact portion 12 is displaced toward the support portion 11. As described above, the elastic arm portion 13 is elastically deformed in two stages, whereby stress concentration on the elastic arm portion 13 can be prevented, durability can be improved, and the life can be extended.
　図６に、圧接端子１０の圧接部１２に負荷される荷重に対する圧接部１２の変位量を示す。圧接部１２に荷重を負荷すると、第１腕部１４が支持部１１に向かって弾性変形し、荷重に比例して圧接部１２の変位量が大きくなる。ついで、第２屈曲部１８が支持部１１に当接するＡ点を超えて荷重を負荷すると、第２腕部１７が支持部１１に向かって弾性変形し、荷重に比例して圧接部１２の変位量が大きくなる。第１腕部１４と第２腕部１７とに同じ荷重を負荷しても、第２腕部１７の変位量が第１腕部１４よりも少ないことが分かる。 FIG. 6 shows a displacement amount of the press contact portion 12 with respect to a load applied to the press contact portion 12 of the press contact terminal 10. When a load is applied to the pressure contact portion 12, the first arm portion 14 is elastically deformed toward the support portion 11, and the displacement amount of the pressure contact portion 12 increases in proportion to the load. Subsequently, when a load is applied beyond the point A where the second bent portion 18 contacts the support portion 11, the second arm portion 17 is elastically deformed toward the support portion 11, and the displacement of the press contact portion 12 is proportional to the load. The amount increases. It can be seen that even when the same load is applied to the first arm portion 14 and the second arm portion 17, the displacement amount of the second arm portion 17 is smaller than that of the first arm portion 14.
　次に、圧接端子１０の製造方法を説明する。 Next, a method for manufacturing the press contact terminal 10 will be described.
　図７（Ａ）に示すように、圧接端子１０を成形するために、正方形板状で絶縁性の型枠４と、型枠４の下側に配設され、かつ、型枠４と同じ形状の導電性基材６とを用いる。型枠４には、圧接端子１０と同一平面形状のキャビティ５が作製されている。図７（Ｂ）に示すように、キャビティ５は型枠４を貫通しているので、キャビティ５の底部から導電性基材６が露出している。 As shown in FIG. 7A, in order to mold the press contact terminal 10, it is a square plate-shaped insulating mold 4, and is disposed below the mold 4 and has the same shape as the mold 4. The conductive substrate 6 is used. A cavity 5 having the same planar shape as that of the press contact terminal 10 is formed in the mold 4. As shown in FIG. 7B, since the cavity 5 penetrates the mold 4, the conductive substrate 6 is exposed from the bottom of the cavity 5.
　圧接端子１０は、型枠４と導電性基材６とを母型とし、以下の工程からなる電鋳法により成形される。電鋳法における電着工程では、母型を電解槽（図示せず）の電解液内に配置し、導電性基材６と、導電性基材６に対向するように配置された対向電極（図示せず）との間に直流電源で電圧を印加し、電解液に電流を流す。通電を開始すると、電解液中の金属イオンが導電性基材６の表面に電着し、金属が析出する。このとき、型枠４の露出する表面は絶縁性であるので、電流を遮断する。このため、母型と対向電極との間に電圧を印加しても、型枠４には直接金属が電着しない。この結果、図８（Ａ）および（Ｂ）に示すように、キャビティ５の内部にはその底面から矢印で示す電圧印加方向に沿って金属層７が成長し、この金属層７により圧接端子１０が成形される。 The press contact terminal 10 is formed by an electroforming method including the following steps using the mold 4 and the conductive base 6 as a mother mold. In the electrodeposition process in the electroforming method, the matrix is placed in an electrolytic solution of an electrolytic cell (not shown), and the conductive substrate 6 and a counter electrode (so as to face the conductive substrate 6) ( A voltage is applied with a direct current power source between them (not shown) and a current is passed through the electrolyte. When energization is started, metal ions in the electrolytic solution are electrodeposited on the surface of the conductive substrate 6, and metal is deposited. At this time, since the exposed surface of the mold 4 is insulative, the current is interrupted. For this reason, even if a voltage is applied between the mother die and the counter electrode, the metal is not directly electrodeposited on the mold 4. As a result, as shown in FIGS. 8A and 8B, the metal layer 7 grows from the bottom surface along the voltage application direction indicated by the arrow in the cavity 5, and the press contact terminal 10 is formed by the metal layer 7. Is formed.
　圧接端子１０が形成されると、図９（Ａ）および（９）に示すように、エッチング等によって型枠４を剥離させることで、導電性基材６の上面には、圧接端子１０素子が取り外し可能な状態で残存する。このようにして成形された圧接端子１０は、電鋳法における電圧印加方向と垂直な方向に弾性変形可能な弾性腕部１３と、その弾性腕部１３の弾性力によって外部導体に圧接可能な圧接部１２とを備えているため、小型で変位量の大きい圧接端子１０が実現できる。 When the press contact terminal 10 is formed, the press contact terminal 10 element is formed on the upper surface of the conductive substrate 6 by peeling the mold 4 by etching or the like, as shown in FIGS. Remains removable. The press contact terminal 10 thus molded includes an elastic arm portion 13 that can be elastically deformed in a direction perpendicular to the voltage application direction in electroforming, and a press contact that can be press contacted to an external conductor by the elastic force of the elastic arm portion 13. Since the portion 12 is provided, the press contact terminal 10 having a small size and a large displacement can be realized.
　また、圧接端子１０を電鋳法で形成することによって、キャビティ５の幅に対して、キャビティ５の深さを大きくすることができる（図８（Ｂ）参照）ため、圧接端子１０の厚みに対して圧接端子１０の幅を大きくできる（図９（Ｂ）参照）。具体的には、弾性腕部１３の厚みに対して、弾性腕部１３の幅を大きくでき、圧接部１２を支持部１１に向かって押圧したときに、弾性腕部１３に捩れが生じることなく、安定した弾性変形を得ることが可能になる。さらに、支持部１１の厚みに対して、支持部１１の幅を大きくでき、支持部１１を基板１（図１参照）に安定して固定することが可能になる。なお、弾性腕部１３および支持部１１の厚みに対するそれぞれの幅は２倍以上（アスペクト比２以上）が好ましい。 Further, by forming the press contact terminal 10 by electroforming, the depth of the cavity 5 can be made larger than the width of the cavity 5 (see FIG. 8B). On the other hand, the width of the press contact terminal 10 can be increased (see FIG. 9B). Specifically, the width of the elastic arm portion 13 can be increased with respect to the thickness of the elastic arm portion 13, and the elastic arm portion 13 is not twisted when the pressure contact portion 12 is pressed toward the support portion 11. It becomes possible to obtain a stable elastic deformation. Furthermore, the width of the support portion 11 can be increased with respect to the thickness of the support portion 11, and the support portion 11 can be stably fixed to the substrate 1 (see FIG. 1). In addition, each width | variety with respect to the thickness of the elastic arm part 13 and the support part 11 is preferable 2 times or more (aspect ratio 2 or more).

The elastic arm portion 24 includes a bent portion 25 and an extending portion 26 and supports the pressure contact portion 23 in a cantilever manner. The bent portion 25 is connected to the end portion of the support portion 21 and has a lateral V shape extending in a front view toward the side. The extending portion 26 extends obliquely upward from the upper end portion of the bent portion 25 inward.
　一対の圧接部２３，２３は、弾性腕部２４，２４の先端部に設けられ、間隔を隔てて互いに対向するように配置されている。圧接部２３，２３の間の距離は、取付保持部２２の支持部２１に平行な距離よりも長い。圧接部２３，２３は、後述する延在部２６が延びる方向と直交する半円柱形状である。 The pair of pressure contact portions 23, 23 are provided at the distal end portions of the elastic arm portions 24, 24, and are disposed so as to face each other with a gap therebetween. The distance between the press contact portions 23, 23 is longer than the distance parallel to the support portion 21 of the attachment holding portion 22. The press contact portions 23, 23 have a semi-cylindrical shape orthogonal to a direction in which an extension portion 26 described later extends.
　そして、図１０（Ｃ）に示すように、圧接部２３，２３を下方に押圧すると、弾性腕部２４，２４が支持部２１に向かって弾性変形する、具体的には、弾性腕部２４の屈曲部２５を中心に圧接部２３が下方に向かって変位し、延在部２６が湾曲して支持部２１に当接する。圧接部２３と弾性腕部２４とをそれぞれ一対設けることで、一方の弾性腕部２４への応力の集中を防止でき、耐久性を高めて寿命を長くできる。 Then, as shown in FIG. 10C, when the pressure contact portions 23, 23 are pressed downward, the elastic arm portions 24, 24 are elastically deformed toward the support portion 21. Specifically, the elastic arm portions 24 The press contact portion 23 is displaced downward around the bent portion 25, and the extending portion 26 is curved and comes into contact with the support portion 21. By providing a pair of the pressure contact portion 23 and the elastic arm portion 24, stress concentration on one elastic arm portion 24 can be prevented, durability can be increased, and the life can be extended.
