Description

本発明は、主に振動用アクチュエータ等の電子部品を電子機器筐体等の基板以外の箇所に取り付ける際に使用する電子部品接続用端子及びそれを使用した電子部品の取付け構造に関する。   The present invention mainly relates to an electronic component connecting terminal used when an electronic component such as a vibration actuator is attached to a location other than a substrate such as an electronic device casing, and an electronic component mounting structure using the same.

従来、振動アクチュエータ等の電子部品の取付け構造としては、電子機器内に収容された実装基板上に振動アクチュエータ等の電子部品を配置し、その端子を実装基板上のパターンに半田付けすることにより実装基板に電子部品を直接取り付ける構造(表面実装)が広く知られている。   Conventionally, the mounting structure of electronic parts such as vibration actuators is mounted by placing electronic parts such as vibration actuators on a mounting board housed in electronic equipment and soldering the terminals to the pattern on the mounting board. A structure (surface mounting) in which an electronic component is directly attached to a substrate is widely known.

一方、電子部品の取付け構造には、ヒューズクリップ等のように導電性金属板材をプレス加工することにより形成されたクリップ型端子を使用し、このクリップ型端子を電子機器の所望の位置に固定し、一対のバネ状の挟持片からなるクリップ部に電子部品の接続端子を挟持させることにより、実装基板やその他の箇所に半田に依らず電子部品を取り付けるようにしたものも知られている(例えば、特許文献1を参照)。   On the other hand, the electronic component mounting structure uses a clip-type terminal formed by pressing a conductive metal plate material such as a fuse clip, and this clip-type terminal is fixed at a desired position of the electronic device. In addition, it is also known that an electronic component is attached to a mounting board or other location without depending on solder by holding a connection terminal of the electronic component in a clip portion formed of a pair of spring-like holding pieces (for example, , See Patent Document 1).

次に、本発明に係る電子部品接続用端子の実施の態様を図1、図2に示した実施例に基づいて説明する。   Next, an embodiment of the electronic component connecting terminal according to the present invention will be described based on the embodiment shown in FIGS.

この電子部品接続用端子1は、弾性を有する導電性金属製の端子用線材を曲げ加工、即ち、ワイヤーフォーミングすることにより一体に形成され、端子用線材を折り返し状に曲げてなるリード線接続部11と、リード線接続部11の端より螺旋状に連続したコイル部12と、コイル部12より前方に延出した一対の弾性接触部13,13とを備えている。   This electronic component connecting terminal 1 is formed integrally by bending a wire for terminal made of conductive metal having elasticity, that is, wire forming, and a lead wire connecting portion formed by bending the wire for terminal into a folded shape. 11, a coil portion 12 that is spirally continuous from the end of the lead wire connecting portion 11, and a pair of elastic contact portions 13 and 13 that extend forward from the coil portion 12.

リード線接続部11は、端子用線材の略中央部分を折り返し状に曲げてU字状に形成され、その折り返し部分にリード線2の先端を引っ掛け、半田付けするようになっている。   The lead wire connecting portion 11 is formed in a U shape by bending a substantially central portion of the terminal wire in a folded shape, and the tip of the lead wire 2 is hooked on the folded portion and soldered.

尚、本実施例では、リード線接続部11をU字状に折り返した例について説明したが、折り返し状は、リード線接続部11を構成する端子用線材の両端断面が同じ向き、且つ、互いに水平方向で間隔おいて位置するように曲げられた状態であればよく、U字状に限定されず、V字状、W字状等のその他の形状であってもよい。   In addition, although the present Example demonstrated the example which folded the lead wire connection part 11 in the U shape, the both ends cross-section of the wire material for terminals which comprises the lead wire connection part 11 is the same direction, and it is mutually As long as it is bent so as to be positioned at intervals in the horizontal direction, it is not limited to a U shape, and may be other shapes such as a V shape and a W shape.

コイル部12は、端子用線材をリード線接続部11の端より旋回半径方向を略水平に向けた螺旋状に曲げて形成され、終端側が上側反時計回りに旋回する上コイル121と、終端側が下側時計回りに旋回する下コイル122とを備え、上下各コイル121,122が上下(コイル中心軸方向)に重なりあって一つのコイル部12を形成している。   The coil portion 12 is formed by bending a terminal wire from the end of the lead wire connecting portion 11 into a spiral shape whose turning radius direction is substantially horizontal, and the end side turns counterclockwise on the upper side, and the end side is A lower coil 122 that turns clockwise is provided, and the upper and lower coils 121 and 122 overlap in the vertical direction (coil central axis direction) to form one coil portion 12.

従って、コイル部12全体は、上から下に向けて時計回りに旋回した螺旋状を成し、リード線接続部11は、そのコイル部12の一部(中間部)を外側に向けて折り返し状(U字状)に引き出した構造になっている。   Accordingly, the entire coil portion 12 has a spiral shape that turns clockwise from top to bottom, and the lead wire connecting portion 11 is folded back with a part (intermediate portion) of the coil portion 12 facing outward. It has a structure that is drawn out (U-shaped).

本実施例では、上下各コイル121,122の巻き数をそれぞれ1としているが、この電子部品接続用端子1では、コイル部12の巻き数は変更可能であって、上下各コイル121,122の巻き数を変更することにより弾性接触部13,13の接触バネ圧を調整できるようになっている。   In this embodiment, the number of turns of each of the upper and lower coils 121 and 122 is set to 1, but in this electronic component connecting terminal 1, the number of turns of the coil portion 12 can be changed. The contact spring pressure of the elastic contact portions 13 and 13 can be adjusted by changing the number of turns.

上下各コイル121,122の終端は、それぞれ相反する外向きに延出し、その終端より端子用線材を前方に曲げることによりコイル部12の両端より前方に延出した一対の両弾性接触部13,13が形成されている。   The ends of the upper and lower coils 121 and 122 extend outwardly opposite to each other, and a pair of elastic contact portions 13 extended forward from both ends of the coil portion 12 by bending the terminal wire forward from the ends. 13 is formed.

弾性接触部13,13は、図2(b)(c)に示すように、各コイル121,122の終端から前方に向けて曲げられたバネ基部131と、バネ基部131の先端より前方に向けて延出する延出部132と、延出部132の先端部に内向きに膨出した円弧状の接点部133とを備えている   As shown in FIGS. 2B and 2C, the elastic contact portions 13 and 13 include a spring base portion 131 bent forward from the end of each coil 121 and 122, and a forward direction from the tip of the spring base portion 131. And an arcuate contact portion 133 that bulges inwardly at the distal end of the extension portion 132.

各バネ基部131は、それぞれ上下コイル121,122の終端より上下方向(コイル軸方向)中央側に向けて傾斜するように曲げられ、両接点部133,133の上下位置が一致するように形成されている。   Each spring base 131 is bent so as to incline toward the center in the vertical direction (coil axial direction) from the terminal ends of the upper and lower coils 121 and 122, and is formed so that the vertical positions of both contact portions 133 and 133 coincide. ing.

接点部133は、端子用線材を延出部132の先端部より内側に向けて円弧状又は山形状に曲げるとともに、その先端側を外側上向きに傾けて曲げることにより接続端子案内部134が形成されている。   The contact portion 133 is formed with a connection terminal guide portion 134 by bending the terminal wire in an arc shape or a mountain shape toward the inner side from the distal end portion of the extending portion 132 and bending the distal end side to be inclined upward outward. ing.

このように構成された電子部品接続用端子1は、プレス金型を必要としない線材曲げ加工により一体に形成されているため、電子部品3の接続端子32を挟持する一対の弾性接触部13,13と、リード線を接続するためのループ状のリード線接続部11とが一体化された複雑な端子形状であっても、初期導入費用を安く抑えられ、設計変更等にも容易に対応することができる。   Since the electronic component connecting terminal 1 configured in this way is integrally formed by wire bending which does not require a press die, a pair of elastic contact portions 13 sandwiching the connection terminal 32 of the electronic component 3, 13 and a complicated terminal shape in which a loop-like lead wire connecting portion 11 for connecting a lead wire is integrated, the initial introduction cost can be kept low, and a design change can be easily handled. be able to.

また、この電子部品接続用端子1では、リード線接続部11の端より螺旋状に連続したコイル部12を備えたことにより、弾性接触部13,13の接触バネ圧を均一且つ所望のバネ圧に設定することができる。   Further, the electronic component connecting terminal 1 includes the coil portion 12 that is spirally continuous from the end of the lead wire connecting portion 11, so that the contact spring pressure of the elastic contact portions 13, 13 is uniform and desired spring pressure. Can be set to

更に、この電子部品接続用端子1は、上下コイル121,122の中心軸が互いにずれないようにコイル部12を固定することにより、弾性接触部13に作用する接続端子32からの反力をコイル部12で吸収し、弾性接触部13,13の弾性変形によるリード線接続部11の変形を防止でき、安定したリード線接続状態を維持することができる。   Further, the electronic component connecting terminal 1 is configured to fix the coil portion 12 so that the central axes of the upper and lower coils 121 and 122 are not displaced from each other, thereby generating a reaction force from the connecting terminal 32 acting on the elastic contact portion 13. Absorbed by the portion 12, deformation of the lead wire connecting portion 11 due to elastic deformation of the elastic contact portions 13, 13 can be prevented, and a stable lead wire connecting state can be maintained.

次に、この電子部品接続用端子1を使用した電子部品の取付け構造を図3〜図5に基づいて説明する。尚、上述の実施例と同様の構成には同一符号を付して説明する。   Next, an electronic component mounting structure using the electronic component connection terminal 1 will be described with reference to FIGS.
