Description

本発明は、プレスフィット端子およびプレスフィット端子の製造方法に関し、詳しくはスルーホールへの圧入後の端子の保持力を向上できると共に、製造過程における端子の成形性を向上させるようにしたものである。   The present invention relates to a press-fit terminal and a method for manufacturing a press-fit terminal, and more specifically, can improve the holding force of a terminal after press-fitting into a through hole and improve the formability of the terminal in the manufacturing process. .

従来、プリント回路基板のスルーホールに挿入されてその内周に形成された接点部との間で電気的接続を取るために用いられる端子として、半田付けを行わずにスルーホールに圧入して接触固定するようにしたプレスフィット端子が知られている。一例として、特許文献１に記載のものは、図５（Ａ）に示すように、ニードルアイ形状とも称されるものであって、一対の弾性当接部２ａ、２ｂが、中央の撓み空間３を挟んで外側へ膨出形成されることで、径方向へ弾性変形可能な構造となっている。そして、このプレスフィット端子１は、両側の弾性当接部２ａ、２ｂが内方へ閉じるように弾性変形しつつプリント回路基板４のスルーホール５に挿入され、その開き方向への弾発力によりスルーホール５内周面に押し付けられて、抜け止めが図られると共に、スルーホール５の接点部６との電気的接続が取られるようになっている。
特公平６−２８１７４号公報 Conventionally, as a terminal used to establish electrical connection with a contact portion that is inserted into a through hole of a printed circuit board and formed on the inner periphery of the printed circuit board, the contact is made by press-fitting the through hole without soldering. A press-fit terminal that is fixed is known. As an example, the device described in Patent Document 1 is also referred to as a needle eye shape as shown in FIG. 5 (A), and a pair of elastic contact portions 2a and 2b are provided in the central bending space 3. As a result of bulging outwardly across the surface, the structure is elastically deformable in the radial direction. The press-fit terminal 1 is inserted into the through hole 5 of the printed circuit board 4 while being elastically deformed so that the elastic contact portions 2a and 2b on both sides are closed inward, and the elastic force in the opening direction is It is pressed against the inner peripheral surface of the through hole 5 to prevent it from coming off and to be electrically connected to the contact portion 6 of the through hole 5.
Japanese Examined Patent Publication No. 6-28174

一般に上記のようなニードルアイ形状のプレスフィット端子１において、スルーホール５に対する保持力を高めるには、弾性当接部２ａ、２ｂの反力を強める必要がある。即ち、弾性当接部２ａ、２ｂは両持ち梁として構成されているため、梁の計算式に当てはめた場合ｗ＝Ｗｌ3／４８ＥＩ（ｗ：撓み、Ｗ：反力、ｌ：梁の長さ、Ｅ：ヤング率、Ｉ：断面二次モーメント）となり、弾性当接部２ａ、２ｂの反力Ｗを高めるには、断面二次モーメントＩを大きくする必要がある。この断面二次モーメントＩは、Ｉ＝ａｈ3／１２（ｈ：撓み方向の梁の高さ、ａ：梁の幅）となり、弾性当接部２ａ、２ｂの撓み方向の厚みを確保することが反力を高めるのに効果的であることが判る。 Generally, in the needle eye-shaped press-fit terminal 1 as described above, in order to increase the holding force with respect to the through hole 5, it is necessary to increase the reaction force of the elastic contact portions 2a and 2b. That is, since the elastic contact portions 2a and 2b are configured as doubly supported beams, when applied to the beam calculation formula, w = Wl 3 / 48EI (w: deflection, W: reaction force, l: beam length) E: Young's modulus, I: sectional secondary moment), and in order to increase the reaction force W of the elastic contact portions 2a, 2b, the sectional secondary moment I needs to be increased. The moment of inertia of area I is, I = ah 3/12 ( h: deflection direction of the beam height, a: beam width), and the elastic contacting portion 2a, to ensure the deflection direction of the thickness of 2b It turns out that it is effective in increasing the reaction force.

しかしながら、ニードルアイ形状のプレスフィット端子１における圧接部の撓み空間３は、プレス成形による打ち抜きによって形成されるが、圧接部は細幅で肉厚となっているため、撓み空間３の幅をより細くして弾性当接部２ａ、２ｂの撓み方向の高さ寸法を確保するように打ち抜き形成することは成形性がわるく非常に困難であるという問題があった。   However, the bending space 3 of the press contact portion in the needle eye-shaped press-fit terminal 1 is formed by punching by press molding. However, since the press contact portion is thin and thick, the width of the flex space 3 is further increased. There is a problem that it is very difficult to form by punching so that the elastic contact portions 2a and 2b are thin and ensure the height dimension in the bending direction.

本発明は上記した問題に鑑みてなされたもので、プレスフィット端子における細幅、肉厚の圧接部に対し、弾性当接部の反力を増強すべくその撓み空間となる開口部の幅をより細くしたプレスフィット端子およびその製造方法を提供することを課題としている。   The present invention has been made in view of the above-described problems, and the width of the opening serving as a flexure space is increased in order to enhance the reaction force of the elastic contact portion with respect to the narrow and thick press contact portion in the press-fit terminal. It is an object of the present invention to provide a press-fit terminal that is thinner and a manufacturing method thereof.

上記課題を解決するため、本発明は、プリント回路基板のスルーホールに圧入されることで該スルーホールの内周に形成された接点部と電気的に接触可能な圧接部を備え、該圧接部は中心部に形成した縦長の開口部を撓み空間として弾性的に変形可能な一対の弾性当接部からなるプレスフィット端子において、
上記開口部は上記弾性当接部の撓み方向と直交する厚み方向の両側から中心部へ向かって凹部が対向してプレス成形されると共に、該凹部によって薄肉とされた底部をプレスによって打ち抜くことで形成されていることを特徴とするプレスフィット端子を提供している。 In order to solve the above-described problems, the present invention includes a pressure contact portion that can be brought into electrical contact with a contact portion formed on the inner periphery of the through hole by being press-fitted into the through hole of the printed circuit board. Is a press-fit terminal composed of a pair of elastic contact portions that can be elastically deformed with a vertically long opening formed in the center as a bending space,
The opening is press-molded with the recesses facing each other from both sides of the thickness direction orthogonal to the bending direction of the elastic contact portion toward the center, and the bottom portion made thin by the recesses is punched out by pressing. There is provided a press-fit terminal characterized by being formed.

上記構成によれば、弾性当接部の撓み空間となる開口部は凹部によって薄肉にされた部分に形成されているため、プレスによる打ち抜き加工が容易となり弾性当接部の撓み空間としての必要最小限の幅に設定することができる。よって、従来のものに比し各弾性当接部の撓み方向の高さ寸法を大きくして、その反力を高めることができる。   According to the above configuration, since the opening serving as the bending space of the elastic contact portion is formed in the thinned portion by the recess, punching by a press is facilitated, and the minimum necessary space as the bending space of the elastic contact portion. It can be set to a limit width. Therefore, the reaction force can be increased by increasing the height dimension of each elastic contact portion in the bending direction as compared with the conventional one.

上記凹部は上記弾性当接部の厚み方向の両側から中心部へ向かうに従い細幅となる台形状に凹設するのが好ましい。
このようにすれば、圧接部に対する凹部の成形過程において開口部の打ち抜きに必要な部分のみ深く凹設することができるため、弾性当接部の強度を低下させることなく撓み方向の高さ寸法を確保して反力を高めることができる。 The recess is preferably recessed in a trapezoidal shape that becomes narrower from both sides of the elastic contact portion in the thickness direction toward the center.
In this way, since only the portion necessary for punching the opening can be deeply recessed in the process of forming the recess with respect to the press contact portion, the height dimension in the bending direction can be reduced without reducing the strength of the elastic contact portion. It can be secured to increase the reaction force.

また、他の発明では、プリント回路基板のスルーホールに圧入されることで該スルーホールの内周に形成された接点部と電気的に接触可能な圧接部を備え、該圧接部は中心部に形成した縦長の開口部を撓み空間として弾性的に変形可能な一対の弾性当接部からなるプレスフィット端子の製造方法であって、
上記開口部は互いに対向する断面台形状のパンチおよびダイによって上記弾性当接部の撓み方向と直交する厚み方向の両側から中心部へ向かうに従い細幅となる台形状の凹部を対向してプレス成形する工程と、該凹部によって細幅の薄肉とされた底部をプレスによって打ち抜く工程とを含むことを特徴とするプレスフィット端子の製造方法を提供している。 According to another aspect of the present invention, a pressure contact portion that can be brought into electrical contact with a contact portion formed on an inner periphery of the through hole by being press-fitted into the through hole of the printed circuit board is provided at the center portion. A method of manufacturing a press-fit terminal comprising a pair of elastic contact portions that can be elastically deformed with the formed vertically long opening as a bending space,
The opening is press-molded with a trapezoidal concave portion that becomes narrower from both sides in the thickness direction perpendicular to the bending direction of the elastic contact portion toward the center by a trapezoidal punch and die having a cross-section facing each other. And a method of manufacturing a press-fit terminal, comprising: a step of punching out a bottom portion which is thinned by the concave portion by pressing.

上記工程によれば、弾性当接部の撓み空間として機能する開口部を必要最小限の細幅に打ち抜き成形するプレス加工の加工性を向上させることができる。これにより従来のニードルアイ形状のプレスフィット端子より弾性当接部の反力を高くしたプレスフィット端子をプレス成形により量産することが可能となる。   According to the said process, the workability of the press work which punches and shape | molds the opening part which functions as a bending space of an elastic contact part to the minimum width required can be improved. As a result, it is possible to mass-produce press-fit terminals whose reaction force of the elastic contact portion is higher than that of a conventional needle-eye press-fit terminal by press molding.

以上の説明より明らかなように、本発明のプレスフィット端子およびプレスフィット端子の製造方法によれば、弾性当接部の反力を高めてスルーホールに対する保持力を強化することができると共に、その加工性も向上することができる。   As is clear from the above description, according to the press-fit terminal and the method of manufacturing the press-fit terminal of the present invention, the reaction force of the elastic contact portion can be increased and the holding force against the through hole can be enhanced. Workability can also be improved.

以下、本発明の実施形態を図面を参照して説明する。
図１〜図４は、本発明のプレスフィット端子１１の実施形態を示し、このプレスフィット端子１１は、プリント回路基板２１のスルーホール２２に圧入されるもので、導電性の金属線をプレス加工することにより、断面長方形の細長い角棒状に形成されている。一方、図４に示すように、プリント回路基板２１の表面には所要の導電路（図示せず）が形成されると共に、この導電路の所要個所に多数のスルーホール２２が開口形成され、各スルーホール２２の内周面にはメッキ処理等によって全周にわたり導電性の接点部２３が形成されている。プレスフィット端子１１はこのスルーホール２２に挿入されることで接点部２３を介して対応する導電路と電気的な接触が得られるようになっている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 4 show an embodiment of a press-fit terminal 11 according to the present invention. The press-fit terminal 11 is press-fitted into a through hole 22 of a printed circuit board 21 and presses a conductive metal wire. By doing so, it is formed in an elongated rectangular bar shape having a rectangular cross section. On the other hand, as shown in FIG. 4, a required conductive path (not shown) is formed on the surface of the printed circuit board 21, and a large number of through holes 22 are formed at required portions of the conductive path. A conductive contact portion 23 is formed on the inner peripheral surface of the through hole 22 over the entire periphery by plating or the like. The press-fit terminal 11 is inserted into the through-hole 22 so that electrical contact with the corresponding conductive path can be obtained through the contact portion 23.

プレスフィット端子１１は一端を他の端子等と接続される端子接続部（図示せず）とし、他端をプリント回路基板２１の接点部２３に圧接される基板接続部１２としている。この基板接続部１２には挿入方向先端部にスルーホール２２への挿入を案内するための先細り状の案内部１３を形成すると共に、この案内部１３の手前位置にはスルーホール２２の深さ寸法より長い領域にわたってスルーホール２２に対する圧接部１４を形成している。この圧接部１４の中心部には長さ方向に延びる縦長の開口部１５を形成し、この開口部１５を撓み空間として弾性的に変形可能な左右一対の弾性当接部１６ａ、１６ｂを形成している。   One end of the press-fit terminal 11 is a terminal connection part (not shown) connected to another terminal or the like, and the other end is a board connection part 12 pressed against the contact part 23 of the printed circuit board 21. The board connection portion 12 is formed with a tapered guide portion 13 for guiding insertion into the through hole 22 at the distal end in the insertion direction, and the depth dimension of the through hole 22 is located at a position in front of the guide portion 13. The pressure contact portion 14 with respect to the through hole 22 is formed over a longer region. A vertically long opening 15 extending in the length direction is formed at the center of the pressure contact portion 14, and a pair of left and right elastic contact portions 16a and 16b that can be elastically deformed with the opening 15 as a bending space is formed. ing.

各弾性当接部１６ａ、１６ｂは、肉厚の両持ち梁構造をなし、開口部１５を挟んで外方へ弧状に膨出形成し、その外面間の寸法はスルーホール２２の内径より大きい寸法とされている。これにより、弾性当接部１６ａ、１６ｂからなる圧接部１４をスルーホール２２内へ挿入したとき、開口部１５を撓み空間として各弾性当接部１６ａ、１６ｂが内方へ弾性的に撓み変形することで、その外面がスルーホール２２内周の接点部２３に圧接されるようになっている。   Each of the elastic contact portions 16a and 16b has a thick double-supported beam structure, bulges outward in an arc shape across the opening 15, and the dimension between the outer surfaces is larger than the inner diameter of the through hole 22. It is said that. As a result, when the pressure contact portion 14 composed of the elastic contact portions 16a and 16b is inserted into the through hole 22, the elastic contact portions 16a and 16b are elastically bent and deformed inward with the opening 15 as a bending space. Thus, the outer surface is brought into pressure contact with the contact portion 23 on the inner periphery of the through hole 22.

開口部１５の中心部では、は図１（Ｃ）に示すように、内周部分が薄肉、細幅とされた断面形状を有している。図２に示すように、この開口部１５を形成するには、先ず形成すべき開口部１５の長さより若干長く圧接部１４の上下両側面、即ち弾性当接部１６ａ、１６ｂの撓み方向と直交する厚み方向の両側から中心部へ向かうに従い細幅となる断面台形状のパンチ３１およびダイ３２を対向させる。次いで、パンチ３１とダイ３２との間にプレスフィット端子１１の圧接部１４を配置して両者間でプレス成形することで両面に断面台形状の凹部１５ａを形成する。両面に形成された凹部１５ａの底部１５ｂ間の厚みは、弾性当接部１６ａ、１６ｂの厚みの略半分となり、その幅も凹部１５ａの基部幅の略半分となる。なお、図５（Ｃ）に示すように、従来のプレスフィット端子１では、撓み空間３の幅寸法が上記実施形態における開口部１５の基部側の幅寸法と略同じ広い寸法となっている。   As shown in FIG. 1C, the central portion of the opening 15 has a cross-sectional shape in which the inner peripheral portion is thin and narrow. As shown in FIG. 2, in order to form the opening 15, first, it is slightly longer than the length of the opening 15 to be formed and is perpendicular to both the upper and lower side surfaces of the pressure contact portion 14, that is, the bending direction of the elastic contact portions 16 a and 16 b. The punch 31 and the die 32 having a trapezoidal cross section that becomes narrower from both sides in the thickness direction to the center are opposed to each other. Subsequently, the press-contact portion 14 of the press-fit terminal 11 is disposed between the punch 31 and the die 32 and press-molded between the both, thereby forming the concave portions 15a having a trapezoidal cross section on both surfaces. The thickness between the bottom portions 15b of the concave portions 15a formed on both surfaces is substantially half of the thickness of the elastic contact portions 16a and 16b, and the width is also substantially half of the base width of the concave portions 15a. As shown in FIG. 5C, in the conventional press-fit terminal 1, the width dimension of the flex space 3 is substantially the same as the width dimension on the base side of the opening 15 in the above embodiment.

次いで、図３（Ａ）（Ｂ）に示すように、一方の凹部１５ａに対応する第２のダイ３３上に圧接部１４を配置すると共に、底部１５ｂを貫通してスリット１５ｃを形成するための第２のパンチ３４を対向させ、プレスにより底部１５ｂを打ち抜き形成することで細幅のスリット１５ｃを形成する。スリット１５ｃの打ち抜き形成に際しては、底部１５ｂが凹部１５ａの形成により前工程で薄肉にされているため、弾性当接部１６ａ、１６ｂ全体の厚み寸法分を打ち抜き形成する場合に比し極めて小さな力で打ち抜くことができる。このため、開口部１５のスリット１５ｃは弾性当接部１６ａ、１６ｂの撓みに必要な最小限の幅寸法Ｘとすることができる。   Next, as shown in FIGS. 3A and 3B, the press contact portion 14 is disposed on the second die 33 corresponding to the one recess 15a, and the slit 15c is formed through the bottom portion 15b. A narrow slit 15c is formed by making the second punch 34 face each other and punching and forming the bottom portion 15b by pressing. When the slit 15c is punched, the bottom 15b is thinned in the previous process by forming the recess 15a. Therefore, the force is extremely small compared to the case of punching and forming the entire thickness of the elastic contact portions 16a, 16b. Can be punched out. For this reason, the slit 15c of the opening 15 can be set to the minimum width dimension X necessary for the bending of the elastic contact portions 16a and 16b.

図１（Ｃ）に示すように、開口部１５のスリット１５ｃの幅寸法Ｘが小さくなれば、弾性当接部１６ａ、１６ｂの撓み方向の高さ寸法ｈ１を、図５（Ｃ）に示す従来のもの（ｈ）より大きくすることができるので、前述の式より断面２次モーメントＩが大きくなり、よって弾性当接部１６ａ、１６ｂの反力Ｗを従来のものより大きくすることができる。   As shown in FIG. 1C, when the width dimension X of the slit 15c of the opening 15 is reduced, the height dimension h1 of the elastic contact portions 16a and 16b in the bending direction is shown in FIG. Therefore, the secondary moment I of the cross section is larger than that of the above formula, and therefore the reaction force W of the elastic contact portions 16a and 16b can be larger than that of the conventional one.

次に、プリント回路基板２１のスルーホール２２へプレスフィット端子１１を挿入して接点部２３と電気的に接続するには、図４（Ａ）（Ｂ）に示すように、スルーホール２２に挿入すべきプレスフィット端子１１を位置決めした後、受部１７を機械的に押圧する。これにより、プレスフィット端子１１は先端の案内部１３からスルーホール２２内に挿入され、続いて圧接部１４が接点部２３に接触しながら圧入される。このとき、圧接部１４を構成する弾性当接部１６ａ、１６ｂは接点部２３との接触により開口部１５側へ撓み変形して、その弾発力によって接点部２３に圧接される。前述のように弾性当接部１６ａ、１６ｂは大きな反発力を発揮することができるので弾性当接部１６ａ、１６ｂの外面による接点部２３への圧接力が高くなり電気的接続信頼性を向上できると共に、プレスフィット端子１１自体の保持力を向上することができ、長期間にわたり安定した接続状態を維持することができる。   Next, in order to insert the press-fit terminal 11 into the through hole 22 of the printed circuit board 21 and electrically connect it to the contact portion 23, insert into the through hole 22 as shown in FIGS. After positioning the press-fit terminal 11 to be pressed, the receiving portion 17 is mechanically pressed. As a result, the press-fit terminal 11 is inserted into the through hole 22 from the guide portion 13 at the tip, and then the press contact portion 14 is press-fitted while being in contact with the contact portion 23. At this time, the elastic contact portions 16 a and 16 b constituting the pressure contact portion 14 are bent and deformed toward the opening portion 15 by contact with the contact portion 23, and are brought into pressure contact with the contact portion 23 by the elastic force. As described above, since the elastic contact portions 16a and 16b can exhibit a large repulsive force, the pressure contact force to the contact portion 23 by the outer surface of the elastic contact portions 16a and 16b is increased, and the electrical connection reliability can be improved. At the same time, the holding force of the press-fit terminal 11 itself can be improved, and a stable connection state can be maintained over a long period of time.
