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.
　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。 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.

　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１０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 10 of the accompanying drawings.
　（第１実施形態）
　図１および図２（Ａ），（Ｂ）に示すように、第１実施形態の圧接端子１０は、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は正面視が環状であり、対向する位置に支持部１１と圧接部１３とを配置すると共に、前記支持部１１と圧接部１３とを一対の弾性腕部１６ａ，１６ｂとでそれぞれ接続している。 (First embodiment)
As shown in FIG. 1 and FIGS. 2A and 2B, the press contact terminal 10 of the first embodiment is formed of a narrow plate-like body made of metal. The pressure contact terminal 10 has an annular shape when viewed from the front, and a support portion 11 and a pressure contact portion 13 are disposed at opposing positions, and the support portion 11 and the pressure contact portion 13 are connected to each other by a pair of elastic arm portions 16a and 16b. is doing.
　前記支持部１１は圧接端子１０の下端部に設けられた長板状であり、正方形の基板（第１部材）１に半田付けして固定される。 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 square substrate (first member) 1 by soldering.
　前記圧接部１３は、前記支持部１１と対向する上端部に設けられ、その両端部には、圧接端子１０の外周方向に沿って一対の圧接突起１４，１４が形成されている。圧接突起１４は周方向と直交する半円柱形状であり、圧接端子１０の径方向に突出している。 The pressure contact portion 13 is provided at an upper end portion facing the support portion 11, and a pair of pressure contact projections 14 and 14 are formed along the outer peripheral direction of the pressure contact terminal 10 at both ends thereof. The press contact protrusion 14 has a semi-cylindrical shape orthogonal to the circumferential direction, and protrudes in the radial direction of the press contact terminal 10.
　弾性腕部１６ａは外方に湾曲する半円形状であり、支持部１１の一端と圧接部１３の一端とを接続している。前記弾性腕部１６ｂは外方に湾曲する半円形状であり、支持部１１の他端と圧接部１３の他端とを接続している。そして、弾性腕部１６ａ，１６ｂは、支持部１１と圧接部１３とを両端支持している。 The elastic arm portion 16 a has a semicircular shape that curves outward, and connects one end of the support portion 11 and one end of the pressure contact portion 13. The elastic arm portion 16 b has a semicircular shape that curves outwardly, and connects the other end of the support portion 11 and the other end of the press contact portion 13. The elastic arm portions 16a and 16b support the support portion 11 and the pressure contact portion 13 at both ends.
　図２（Ｃ）に示すように、圧接部１３を支持部１１に向かって下方に押圧すると、弾性腕部１６ａ，１６ｂは外方に広がるように撓んで弾性変形する。このとき、弾性腕部１６ａ，１６ｂが支持部１１と圧接部１３とを両端支持しているので、圧接部１３を押圧する負荷が弾性腕部１６ａ，１６ｂで２分割される。このため、応力集中を防止して耐久性を高め、寿命を長くできる。 As shown in FIG. 2C, when the pressure contact portion 13 is pressed downward toward the support portion 11, the elastic arm portions 16a and 16b are bent and elastically deformed so as to spread outward. At this time, since the elastic arm portions 16a and 16b support the support portion 11 and the press contact portion 13 at both ends, the load for pressing the press contact portion 13 is divided into two by the elastic arm portions 16a and 16b. For this reason, stress concentration can be prevented, durability can be enhanced, and the life can be extended.
　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３（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と同一形状のキャビティ５が作製されている。図３（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. 3 (A), in order to mold the press contact terminal 10, a square plate-like insulating mold 4 is provided on the lower side of the mold 4 and has the same shape as the mold 4 The conductive substrate 6 is used. A cavity 5 having the same shape as the press contact terminal 10 is formed in the mold 4. As shown in FIG. 3B, 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４（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 mold 4 is insulative, the current is cut off. 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. 4A and 4B, a metal layer 7 grows in the cavity 5 along the voltage application direction indicated by an arrow from the bottom surface thereof, and the metal layer 7 causes the press contact terminal 10 to grow. Is formed.
　圧接端子１０が形成されると、図５（Ａ）および（Ｂ）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、電鋳法によ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１６ａ，１６ｂと、その弾性腕部１６ａ，１６ｂの弾性力によって外部導体に圧接可能な圧接部１３とを備えるため、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, as shown in FIGS. 5A and 5B, the press contact terminal 10 is removed from the upper surface of the conductive substrate 6 by peeling the mold 4 by etching or the like. Remain in a possible state. The press contact terminal 10 formed in this way is formed into an external conductor by elastic arm portions 16a and 16b that can be elastically deformed in a direction perpendicular to the direction of voltage application by electroforming, and the elastic force of the elastic arm portions 16a and 16b. Since the press-contact portion 13 that can be press-contacted 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４（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５（Ｂ）参照）。具体的には、弾性腕部１６ａ，１６ｂの厚みに対して弾性腕部１６ａ，１６ｂの幅を大きくできので、圧接部１３を支持部１１に向かって押圧したときに、弾性腕部１６ａ，１６ｂ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。 Further, by forming the press contact terminal 10 by electroforming, the depth of the cavity 5 can be increased with respect to the width of the cavity 5 (see FIG. 4B). Thus, the width of the press contact terminal 10 can be increased (see FIG. 5B). Specifically, since the width of the elastic arm portions 16a and 16b can be increased with respect to the thickness of the elastic arm portions 16a and 16b, the elastic arm portions 16a and 16b are pressed when the pressing portion 13 is pressed toward the support portion 11. It is possible to obtain a stable elastic deformation without twisting. Furthermore, the width of the support part 11 can be increased with respect to the thickness of the support part 11, and the support part 11 can be stably fixed to the substrate 1 (see FIG. 1).

The press contact terminal 20 has a substantially elliptical shape in a front view with a short side being a straight line L1 connecting between the pair of support portions 11a and 11b and the center of the press contact portion 13. With this configuration, the distance between the support portions 11a and 11b and the press contact portion 13 is shortened, and the press contact terminal 20 having a short height is obtained.
　弾性腕部２２ａは側方に向かって凸状となる横向きの略Ｖ字形状であり、支持部１１ａの外側端部と圧接部１３の一端とを接続している。また、弾性腕部２２ｂは側方に向かって凸状となる横向きの略Ｖ字形状であり、支持部１１ｂの外側端部と圧接部１３の他端とを接続している。そして、弾性腕部２２ａ，２２ｂは、その両端で支持部１１ａ，１１ｂと圧接部１３とを支持している。更に、弾性腕部２２ａ，２２ｂは、その略中央部を折り曲げた屈曲部２４と、屈曲部２４から圧接部１３まで斜め上方に延びる第１腕部２５と、前記屈曲部２４から支持部１１ａ，１１ｂまで斜め下方に延びる第２腕部２６とを備えている。
　なお、図２の第１実施形態と同一の要素には同一の符号を付して説明を省略する。以下の各実施形態においても同様である。 The elastic arm portion 22a has a substantially V-shape in a lateral direction that is convex toward the side, and connects the outer end portion of the support portion 11a and one end of the press contact portion 13. Further, the elastic arm portion 22b has a substantially V-shape that is convex in the lateral direction, and connects the outer end portion of the support portion 11b and the other end of the press contact portion 13. The elastic arm portions 22a and 22b support the support portions 11a and 11b and the press contact portion 13 at both ends thereof. Further, the elastic arm portions 22a and 22b include a bent portion 24 obtained by bending the substantially central portion thereof, a first arm portion 25 extending obliquely upward from the bent portion 24 to the press contact portion 13, and the support portion 11a, And a second arm portion 26 extending obliquely downward to 11b.
