Description

本発明は、プリント基板のスルーホールに挿入されて、スルーホール内面の導電性膜に電気的に接続される接続端子及びこれを用いた電気部品に関する。   The present invention relates to a connection terminal that is inserted into a through hole of a printed circuit board and is electrically connected to a conductive film on the inner surface of the through hole, and an electrical component using the connection terminal.

従来の接続端子を特許文献１に基づいて説明すると、図８に示すように、プリント基板２１には、所定の孔径のスルーホール２２が貫通形成され、このスルーホール２２の内面に導電性膜２３が形成され、この導電性膜２３に、所定形状の配線パターン２４が接続して引き回し形成されている。
このような、プリント基板２１のスルーホール２２に挿入して接続可能な従来の接続端子３０は、所定厚さの金属板からなり、所定の幅寸法の端子部３１と、この端子部３１の一端部側に接続部３２が一体形成されている。
そして、接続部３２は、プリント基板２１のスルーホール２２に挿入されて電気的に導通可能な形状になっている。 A conventional connection terminal will be described with reference to Patent Document 1. As shown in FIG. 8, a through hole 22 having a predetermined hole diameter is formed through a printed circuit board 21, and a conductive film 23 is formed on the inner surface of the through hole 22. A wiring pattern 24 having a predetermined shape is connected to the conductive film 23 so as to be routed.
Such a conventional connection terminal 30 that can be inserted and connected to the through hole 22 of the printed circuit board 21 is made of a metal plate having a predetermined thickness, and has a terminal portion 31 having a predetermined width dimension and one end of the terminal portion 31. The connection part 32 is integrally formed on the part side.
The connecting portion 32 is inserted into the through hole 22 of the printed board 21 and has a shape that allows electrical connection.

前記接続部３２は、二股状に分かれており、二股状に分かれた部分を、それぞれ樋状にカールさせて一対の弾性片３３が形成されている。
前記一対の弾性片３３は、樋状にカールさせたその凹面側を内側にして、互いに対向形成されて、根元側が片持ち支持されて先端部が自由端状になっている。
前記一対の弾性片３３は、互い外向きに屈曲させて屈曲頂部３４が形成され、この屈曲頂部３４がプリント基板２１のスルーホール２２内面の導電性膜２３に弾接して電気的に導通するようになっている。 The connecting portion 32 is divided into two forks, and a pair of elastic pieces 33 is formed by curling the forks into portions.
The pair of elastic pieces 33 are formed so as to face each other with the concave surface curled in a bowl shape inside, the root side is cantilevered, and the tip part is a free end.
The pair of elastic pieces 33 are bent outwardly to form a bent top 34, and the bent top 34 is elastically contacted with the conductive film 23 on the inner surface of the through hole 22 of the printed circuit board 21 so as to be electrically connected. It has become.

また、一対の弾性片３３は、スルーホール２２に挿入する前は、先端部が開いており、スルーホール２２に挿入されると、それぞれの先端部が閉じて圧接され、弾性片３３の屈曲頂部３４がスルーホール２２の導電性膜２３に強く圧接されるようになっている。
また、端子部３１の一端部側である、接続部３２の根元部分には、円弧状の切り欠き部３５が互いに対向する位置に一対形成されている。
前記切り欠き部３５によって、弾性片３３を樋状にカールさせる時の歪みが端子部３１に伝わることがなく、端子部３１に反り等が発生しないようになっている。
特開２００３−３３８３３３号公報 The pair of elastic pieces 33 are open at the front end portions before being inserted into the through holes 22, and when inserted into the through holes 22, the respective front end portions are closed to be in pressure contact with each other. 34 is strongly pressed against the conductive film 23 of the through hole 22.
A pair of arc-shaped cutout portions 35 are formed at the base portion of the connection portion 32 on one end side of the terminal portion 31 at positions facing each other.
The notch 35 prevents the distortion when the elastic piece 33 is curled like a bowl from being transmitted to the terminal portion 31, so that the terminal portion 31 is not warped.
JP 2003-338333 A

しかし、従来の接続端子３０は、端子部３１の一端部側で接続部３２の根元部分に一対の切り欠き部３５を形成したので、弾性片３３をスルーホール２２に挿入する時に、切り欠き部３５に応力が集中して、切り欠き部３５を形成した部分から変形するおそれがあった。
また、接続部３２は、弾性片３３を樋状にカールさせるために、その加工が複雑となり、カールさせる前の弾性片を形成した部分の幅寸法（ブランク寸法）を、端子部３１の幅寸法より広くしなければならなかった。
そのために、金属材料をプレス等で打ち抜きして、従来の接続端子３０を形成する時に、接続端子３０間のピッチ寸法が広くなって、材料歩留まりが悪くなりコストアップになる問題があった。 However, since the conventional connection terminal 30 has a pair of cutout portions 35 formed at the base portion of the connection portion 32 on one end side of the terminal portion 31, the cutout portion is inserted when the elastic piece 33 is inserted into the through hole 22. There is a possibility that stress concentrates on the portion 35 and the portion where the cutout portion 35 is formed is deformed.
Further, since the connecting portion 32 curls the elastic piece 33 like a bowl, the processing becomes complicated, and the width dimension (blank dimension) of the portion where the elastic piece before curling is formed is the width dimension of the terminal portion 31. Had to be wider.
Therefore, when the conventional connection terminals 30 are formed by punching a metal material with a press or the like, the pitch dimension between the connection terminals 30 is widened, resulting in a problem that the material yield is deteriorated and the cost is increased.

Circuit, and by connecting the elastic contact portion of the connection terminal into the through hole of the printed circuit board, the wiring pattern of the printed circuit board and the circuit are electrically connected through a plurality of elastic contact portions. And

As an eleventh means for solving the above-mentioned problem, the terminal portion of the connection terminal is pulled out from the side surface of the housing and bent at a substantially right angle, and the elastic contact portion passes through the printed circuit board. It can be inserted into a hole.

本発明の接続端子の接続部は、スルーホールの挿入方向に所定長さで形成したスリットによって細長状に分割され、スリットを挟んで隣り合う細長状の分割部分を、金属板の板厚方向に対して互いに異なる方向に屈曲させて、スルーホールの内面に弾接可能な複数の弾接部を形成したので、接続部をスルーホールに挿入する際に、端子部の一部に応力が集中して端支部に変形が発生するのを抑制することができる。また、複数の断絵粒が、金属板の板厚方向に屈曲されることから、材料歩留まりが良く、接続端子を複数本並べて用いる場合に、それぞれの接続端子間の狭ピッチ化が可能となる。
また、接続部がスルーホールに挿入されると、複数の弾接部がスルーホール内面の導電性膜に強く弾接して、接続部を半田付け等でプリント基板に固着しなくても、接続部をプリント基板の配線パターンに電気的に確実に導通させることができる。更に、接続部をプリント基板に半田付けしなくても良いので、組み立て効率を向上できる。
また、スリットは、接続部に所定の間隔を有して２本形成され、この２本のスリットによって弾接部が３つ形成され、この３つの弾接部が互い違いの方向に屈曲形成されているので、３つの弾接部をスルーホール内で３点支持させて、３ケ所でスルーホール内面に各弾接部を確実に強く弾接することができ、よって、接続端子とスルーホール内面の導電性膜との接続信頼性を向上させることができる。 The connection portion of the connection terminal of the present invention is divided into elongated shapes by slits formed in a predetermined length in the through hole insertion direction, and the adjacent elongated divided portions sandwiching the slits in the thickness direction of the metal plate. On the other hand, it was bent in different directions to form a plurality of elastic contact parts that could be elastically contacted with the inner surface of the through hole, so stress was concentrated on a part of the terminal part when the connection part was inserted into the through hole. Thus, deformation of the end support can be suppressed. In addition, since a plurality of cut-off grains are bent in the thickness direction of the metal plate, the material yield is good, and when a plurality of connection terminals are used side by side, it is possible to reduce the pitch between the connection terminals. .
In addition, when the connection part is inserted into the through hole, the plurality of elastic contact parts strongly elastically contact the conductive film on the inner surface of the through hole, so that the connection part does not have to be fixed to the printed circuit board by soldering or the like. Can be electrically and reliably conducted to the wiring pattern of the printed circuit board. Furthermore, since it is not necessary to solder the connecting portion to the printed circuit board, assembly efficiency can be improved.
In addition, two slits are formed at a predetermined interval in the connection portion, and three elastic contact portions are formed by the two slits, and the three elastic contact portions are bent and formed in alternate directions. As a result, the three elastic contact portions are supported at three points in the through hole, and each elastic contact portion can be firmly and firmly in contact with the inner surface of the through hole at three locations. The connection reliability with the conductive film can be improved.

また、３つの弾接部は、２本のスリットに挟まれた部分に形成した第１弾接部と、この第１弾接部の外側に形成した一対の第２弾続部とからなり、第１弾接部は、第２弾続部より幅広に形成されているので、第１弾接部の強度をアップさせて、第１、第２弾接部が導電性膜に弾接する弾接力を高めることができると共に、弾接バランスを良くすることができ、スルーホール内面の導電性膜に対する接続部の電気的な導通を安定させることができる。
また、第１弾続部の長手方向には、スルーホールの内面に弾接可能な凸状のリブが形成されているので、更に第１弾接部を強度アップできる。 Further, the three elastic contact portions are composed of a first elastic contact portion formed in a portion sandwiched between two slits, and a pair of second elastic connection portions formed outside the first elastic contact portion, Since the first elastic contact portion is formed wider than the second elastic connection portion, the strength of the first elastic contact portion is increased, and the elastic force that causes the first and second elastic contact portions to elastically contact the conductive film. In addition, the elastic contact balance can be improved, and the electrical conduction of the connecting portion to the conductive film on the inner surface of the through hole can be stabilized.
Moreover, since the convex rib which can be elastically contacted to the inner surface of the through hole is formed in the longitudinal direction of the first elastic portion, the strength of the first elastic contact portion can be further increased.

また、複数の弾接部は、長手方向の両端部がそれぞれつながって両持ち状になっているので、弾接部の弾性力が大きくなって、スルーホールに弾接部を挿入して嵌合させたときの弾接力を大きくでき、接続の信頼性を向上させることができる。また、複数の弾接部の先端部側がまとまっているので、接続部をスルーホールに挿入しやすくできる。
また、端子部の一端部側には、段部が形成されて端子部が接続部より幅広になっているので、接続部をスルーホールに挿入するときに端子部に曲がり等の変形が発生するのを防止できる。 In addition, the multiple elastic contact parts are connected to each other at both ends in the longitudinal direction, so the elastic force of the elastic contact parts is increased, and the elastic contact parts are inserted into the through holes and fitted. It is possible to increase the elastic contact force when it is applied and to improve the reliability of connection. Moreover, since the front end side of the plurality of elastic contact portions is gathered, the connection portion can be easily inserted into the through hole.
In addition, since a step portion is formed on one end portion side of the terminal portion and the terminal portion is wider than the connection portion, deformation such as bending occurs in the terminal portion when the connection portion is inserted into the through hole. Can be prevented.

また、複数の弾接部は、それぞれ両端部に傾斜部が形成されると共に、これら傾斜部の間に略平坦状の頂部を有する山形状に屈曲形成されているので、接続部をスルーホールに挿入したときに、導電性膜に対する弾接部の弾接面積を大きくすることができ、接続部とスルーホールの導電性膜との電気的な導通を確実にすることができる。
また、傾斜部のスルーホールへの挿入方向に対する傾斜角度が、先端部側が端子部側より小さくなっているので、接続部を無理なくスルーホールに挿入でき、挿入作業性に優れている。 In addition, each of the plurality of elastic contact portions is formed with an inclined portion at both ends, and is bent into a mountain shape having a substantially flat top portion between the inclined portions. When inserted, the elastic contact area of the elastic contact portion with respect to the conductive film can be increased, and electrical connection between the connection portion and the conductive film of the through hole can be ensured.
In addition, since the inclination angle of the inclined portion with respect to the insertion direction into the through hole is smaller on the tip end side than on the terminal portion side, the connecting portion can be inserted into the through hole without difficulty, and the insertion workability is excellent.

また、本発明の電気部品は、請求項１乃至８のいずれかに記載の接続端子と、筐体内に形成されて接続端子に接続される所定の回路とを備え、接続端子の弾接部をプリント基板のスルーホールに挿入することにより、プリント基板の配線パターンと回路とが、複数の弾接部を介して電気的に接続されるので、接続端子をプリント基板に半田付けしなくても、電気的に確実に導通させることができる。
そして、接続端子をプリント基板に半田付けしなくても良いので、本発明の接続端子を用いた電気部品側の筐体を、低コストの熱可塑性樹脂等を用いることができ、電気部品のコストダウンが可能となる。
更に、接続端子とプリント基板との半田付け工程が不要になるので、組立効率を向上できる。また、接続端子の複数の弾接部が金属板の板厚方向に屈曲されたものであるため、複数の接続端子間の狭ピッチ化に対応できる電気製品を提供することができる。
また、所定の回路は、所定形状の固定接点と可動接点とを有し、固定接点と接続端子とが１枚の金属板で一体形成されているので、接続端子を固定接点にカシメあるいは半田付け等で接続しなくて良く、組立効率を更に向上できる。
また、接続端子の端子部は、筐体の側面から引き出され略直角状に折り曲げられ、弾接部がプリント基板のスルーホールに挿入可能になっているので、プリント基板に固着前の仮止め時の電気部品に、外部から衝撃等が加わった場合に、接続端子は、直角状の折り曲げ部から弾性変形する。
そのために、スルーホールに挿入した弾接部が変形するのを防止できる。 An electrical component of the present invention includes the connection terminal according to any one of claims 1 to 8 and a predetermined circuit formed in the housing and connected to the connection terminal, and an elastic contact portion of the connection terminal is provided. By inserting into the through hole of the printed circuit board, the wiring pattern of the printed circuit board and the circuit are electrically connected via a plurality of elastic contact portions, so even if the connection terminal is not soldered to the printed circuit board, Electrical conduction can be ensured.
Since the connection terminals do not have to be soldered to the printed circuit board, a low-cost thermoplastic resin or the like can be used for the housing on the electrical component side using the connection terminals of the present invention. Down is possible.
Furthermore, since the soldering process between the connection terminal and the printed circuit board is not necessary, the assembly efficiency can be improved. Further, since the plurality of elastic contact portions of the connection terminal are bent in the thickness direction of the metal plate, an electrical product that can cope with a narrow pitch between the plurality of connection terminals can be provided.
In addition, the predetermined circuit has a fixed contact and a movable contact having a predetermined shape, and the fixed contact and the connection terminal are integrally formed of a single metal plate, so that the connection terminal is caulked or soldered to the fixed contact. The assembly efficiency can be further improved without the need to connect them with the like.
The terminal part of the connection terminal is pulled out from the side of the housing and bent at a substantially right angle, and the elastic contact part can be inserted into the through hole of the printed circuit board. When an impact or the like is applied to the electrical component from the outside, the connection terminal is elastically deformed from the right-angled bent portion.
Therefore, it is possible to prevent the elastic contact portion inserted into the through hole from being deformed.
