Description

【0001】
【発明の属する技術分野】
本発明は、電子部品を搭載するプリント配線板において、その電気回路の電源、または信号出力ラインを簡易的にON・OFFしたりするための接続用のピンヘッダーに関するものである。
【0002】
【従来の技術】
電子部品を多数搭載するプリント配線板での簡易的な電子回路の電源、または信号出力ラインのON・OFFを簡易的に行う従来の技術について、図6及び図7を用いて説明する。
【0003】
図6に示すように、プリント配線板31の表面上に設けた、パターン32上の銅箔の露出した一定のピッチd33を保ったパッド33aとパッド33b間を半田付けしたり、半田を外したりするためのショートランドを設置して対応していた。また図7において、角ピン34a,34bや丸ピン(図示せず)を専用の自動挿入機(図示せず)でプリント配線板31上のパターン32に設けた取り付け穴35へ挿入し、その間を導電性の良い、金属板よりなるクリップ(図示せず)などで角ピン34a、34bの間をショートさせ、通電していた。またスライドスイッチやトグルスイッチ(共に図示せず)といった機械的接触によって、通電させていた。
【0004】
【発明が解決しようとする課題】
しかしながら、従来のプリント配線板上のショートランドでの半田付けによる電源、または信号出力ラインのON・OFFは、半田付け作業時に、半田クズを発生させ、周囲の電子部品接続回路をショートさせることが多い。また、ショートランド部分の銅箔パターンが剥がれてしまい、そしてショートランドによる電気的接続は、半田付け作業でしか対応できないといった課題があった。
【0005】
また、電気的接続を機械的に行なう手段があるが、これは、スライドスイッチやトグルスイッチなどと呼ばれるものである。これらのスイッチは、電気的接続のON・OFFは、確実に行えるものの、比較的大きなものが多く、プリント配線板上に実装する際、余分なスペースを要するといった課題があった。
【0006】
一方、複数の角ピン、または丸ピンをプリント配線板上に実装する方法では、自動挿入機に制約が有るため、角ピンまたは丸ピンを取り付けるピッチが、一定の間隔以下では、実装不可能であった。すなわち、ピンを実装するための専用の自動実装機が必要となり、一般的に使用されるアキシャル、ラジアル部品に対応した自動実装機では、対応できないばかりか、ピン間が一定の距離以下にならないため、ピン間の接続をする際、導電性の良い金属板などで製作した接続用のクリップなどが、新たに必要になるといった課題があった。
【0007】
【課題を解決するための手段】
本発明は、上記課題を解決するために、所定の形状に曲げられた複数の導電性ピンの導電端に間隔を狭くする圧延部を設け、この導電性ピンを自動実装機の規格に合わせた所定のピッチ樹脂ケースにて固定保持するものである。
【0008】
上記発明によれば、電気的に接続が必要となる導電性ピンの間隔が、任意の間隔で設定でき、電気的接続が特別に導電性のクリップなどを用意せずとも、間隔が狭ければ、導電性ピンの弾性を利用することにより、該当する電気回路を容易にON・OFFすることが可能となる。
【0009】
【発明の実施の形態】
本発明は、所定間隔で平行に穿孔された保持穴を有する樹脂ケースと、前記保持穴に圧入して上部に導電端を突出し、下部に露出した取付脚の少なくとも一方を前記所定間隔とは異なる取付間隔になるように曲げ加工した導電性ピンとで構成し、前記導電端間を狭くする圧延部を設け、前記保持穴の所定間隔を前記取付間隔より小さくしたものである。
【0010】
また前記取付脚の取付ピッチを自動実装機の規格に合わせた導電性ピンと、前記保持穴の所定間隔を取付ピッチより小さくしたものである。
【0012】
また、前記取付脚の取付ピッチを自動実装機の規格に合わせ、前記樹脂ケース上部に突出した導電端の先端はエッジを廃した形状の導電性ピンとしたものである。
【0013】
また、前記導電端の所定の箇所に導電端の径より部分的に細くした絞り部を有する導電性ピンとで構成したものである。
【0014】
また、前記導電性ピンの樹脂ケースへの圧入部分の一部を細径化した絞り部とし、かつ前記取付脚はクランク状に曲げ加工し、樹脂ケースの底面に沿う前記取付脚の並行部が嵌合する溝を樹脂ケースに備えたものである。
【0015】
また、所定間隔に並行して穿孔した保持穴を有する樹脂ケースと、前記保持穴の下端間を仕切る壁を前記樹脂ケース底面より突出させた絶縁壁と、前記導電端の一部に導電端間を狭くする圧延部と、保持穴に圧入して上部に導電端を突出し、下部に露出した取付脚の一方、または双方を前記所定間隔とは異なる取付ピッチに曲げ加工した導電性ピンとで構成したものである。
【0016】
また、前記樹脂ケースは、自動実装機の規格により定められる導電性ピンの取り付けピッチよりも大きくしたものである。
【0017】
また、前記樹脂ケースの導電性ピンの保持穴は、樹脂ケース底面よりの入口形状は、間口を広くしたすり鉢形状とし、所定の距離までは、導電性ピン径よりも大きく、所定の距離から樹脂ケース上側までの保持穴は、導電性ピン径と同径、または、狭くしたものである。
【0018】
以下、本発明のピンヘッダーの実施例について、図面を参照して説明する。
(実施例1)
図1(1)、(2)は本発明の実施例1のピンヘッダーの正面図及び側面図である。また、図2はその断面図である。
【0019】
図1、図2において、所定の形状に曲げられた一対の導電性ピン1は、所定の形状と同一のやや細い径の保持穴2aを持ったABSなどの絶縁性の高い樹脂よりなり、樹脂ケース2に圧入されて固定保持されている。
【0020】
また、導電性ピン1は、樹脂ケース2によって固定される部分の所定の位置に、部分的に線径を細く加工した絞り部3を設けることにより、圧入による樹脂の歪みが、絞り部3の細径部への膨れとして現れるために、導電性ピン1と樹脂ケース2との嵌合力が強まり、導電性ピン1が、容易に樹脂ケース2から外れることを防止することができる。
【0021】
なお、本実施例では、導電性ピン1を2本とし、両方共に、所定の形状に曲げたものとしたが、導電性ピン1の一方は、所定の形状に曲げず、ストレートの状態でも構わない。
【0022】
また、導電性ピン1の先端部分Cの形状をピン径r1より小さくすることにより、不用意に導電性ピン1どうしが、接触することを防止することができる。
【0023】
なお、本実施例では、導電性ピン1の断面形状を丸ピンとしたが、角ピンでも構わない。
【0024】
そして、導電性ピン1は、樹脂ケース2によって、自動実装が可能なように、自動実装機の規格に従い定められた、5mmピッチや7.5mmピッチなどで取り付けピッチd1に固定される。これにより、一般のラジアル部品対応の自動実装機による実装が可能となる。
【0025】
また、樹脂ケース2より上側の導電性ピン1の先端までの間d3における導電性ピン1どうしの間隔d2は、樹脂ケース2より下側の導電性ピン1の間隔d1よりも狭く、かつ、導電性ピン1が互いに間隔d2を保った平行な状態で、樹脂ケース2により固定保持する。
【0026】
このことにより、図1に示したA方向→←、B方向→←の何れの方向からでも、導電性ピン1どうしを金属片などで簡単に接続が可能となり、また、導電性ピン1の間隔d2を容易に半田こてにより、直接に半田付けし、確実に導電性ピン1どうしを接続をすることができる。
【0027】
(実施例2)
図3は、本発明の実施例2のピンヘッダーの正面図である。
【0028】
図3において、樹脂ケース2より上側の導電性ピン1aの導電端の一部に、例えば、導電性ピン1aの先端から樹脂ケース2により固定された根元との間d5の中間部分d4に圧延部4を設ける。
【0029】
このことにより、導電性ピン1aどうしのピッチdpは、樹脂ケース2を成型する際成型上で制約されるが、このピッチdp以下のピン間隔を設定できるため、導電性ピン1aどうしを直接半田付けする必要がある場合半田の流れが向上し、良好な半田付けが可能となると共に、確実に導電性ピン1aどうしの接続をすることができる。
【0030】
また、導電性ピン1a間を直接に半田付けせずとも、導電性ピン1aの間隔dpを狭く設定しているため、導電性ピン1aの有する弾性を利用し、必要な時は導電性ピン1aの間隔dpに軽い応力を印加し、導電性ピン1aどうしを接触させ、必要が無くなれば応力の印加を中止すれば、導電性ピン1aの有する弾性により、導電性ピン1aどうしの接触は解除され、通電状態はON状態からOFF状態に簡単に移行できる。
【0031】
(実施例3)
図4(1)は、本発明の実施例3のピンヘッダーの樹脂ケースの断面図、図4(2)は樹脂ケースの導電性ピンを取り付けるための穴形状図、図5は、樹脂ケースを下面から見た図である。図4(1)において、5は導電性ピン1aを取り付けるための導電性ピン取付穴であり、図4Bに導電性ピン1aを取り付けるための導電性ピン取付穴5の詳細図を示す。図4(1)、(2)を用いて、説明する。まず、樹脂ケース2内の所定の区間d11の穴径d7は、導電性ピン1aと同径または、導電性ピン1aの径よりも若干、小さい径とすることで、樹脂ケース2より上側に突き出る導電性ピン1aのピッチは、安定した状態とすることができる。
【0032】
また、E方向から樹脂ケース2へ導電性ピン1aを取り付けるが、その際、入口からの所定の区間d9が導電性ピン1aの径よりも大きく、かつ入口に向かってすり鉢形状とすることで、導電性ピン1aを取り付け時の挿入が簡単にできることとなる。
【0033】
また、樹脂ケース2へ導電性ピン1aを取り付ける際、樹脂ケース2の下側に導電性ピン1aの接触を防止するための接触防止壁6を設けることにより、不用意なショート状態を避けることが可能となる。
【0034】
さらに、導電性ピン1aをクランク状に曲げることにより樹脂ケース2と接触防止壁6との密着度が向上し、これと同時に嵌合力も強まると共に絶縁性も向上させることができる。
【0035】
そして、樹脂ケース2内の所定の区間d11と、入口からの所定の区間d9に挟まれた区間d10は導電性ピン1aの径よりも若干、大きい径とすることで、樹脂ケース2内の所定の区間d10までは、導電性ピン1aの取り付けが、スムーズとなり、樹脂ケース2内の所定の区間d11の穴径d7は、導電性ピン1aと同径または、導電性ピン1aの径よりも若干、小さい径とすることで、樹脂ケース2より上側に突き出る導電性ピン1aのピッチは保たれ、精度の高い構成とすることができる。
【0036】
【発明の効果】
以上の説明から明らかなように、本発明のピンヘッダーによれば、次の効果が得られる。
【0037】
所定間隔に並行して穿孔した保持穴を有する樹脂ケースと、保持穴に圧入して上部に導電端を突出し、下部に露出した取付脚の一方、または、双方を所定間隔とは異なる取付ピッチに曲げ加工した導電性ピンとを備えたことにより、導電性ピンを樹脂ケースに圧入するだけで組立固定でき、導電端の間隔と取付脚の取付けピッチを各々、自由に設定することができる。
【0038】
また、取付脚の取付ピッチを自動実装機の規格に合わせ、保持穴の所定間隔を取付ピッチより小さくすることにより、自動実装機による自動組立を可能にすることができると共に、導電性ピンの導電端の間隔を取付脚のピッチより狭くでき、例えば半田付による導電端間を容易に短絡することができる。
【0039】
また、樹脂ケースの上部に突出した導電端の一部に導電端間を狭くする圧延部を設けた導電性ピンと、この導電性ピンを固定する樹脂ケースの保持穴の間隔を取付ピッチよりも小さくすることにより、樹脂ケースの成型上で制約される保持穴のピッチよりも導電性ピンどうしの間隔を狭くして設定することが可能となるばかりでなく、導電性ピンの有する弾性を利用することにより、手で軽く応力を印加するだけで導電端間を短絡させることができ、応力の印加を中止することにより、導電端間の短絡を解放可能することができる。
【0040】
また、導電性ピンの樹脂ケースより突出した導電端の先端のエッジを廃した形状とすることにより、導電端どうしが不用意に接触することを避けることができる。
【0041】
また、樹脂ケースの保持穴内部に保持穴径より部分的に小さくした突出部と、導電端の所定の箇所に導電端の径より部分的に細くした絞り部を有することで、樹脂ケースと導電性ピンとの嵌合力は強まることになり、したがって導電性ピンが樹脂ケースから脱落することが防止でき、導電端のガタツキが少なくなり、さらに不必要な導電端間の短絡を避けることが可能となる。
【0042】
また、樹脂ケース下部に接触防止壁を設け、導電性ピンをクランク形状とすることにより、絶縁性と嵌合力を向上させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a connection pin header for easily turning ON / OFF a power supply or a signal output line of an electric circuit in a printed wiring board on which an electronic component is mounted.
[0002]
[Prior art]
A conventional technique for simply turning on / off a power source of a circuit or a signal output line on a printed wiring board on which a large number of electronic components are mounted will be described with reference to FIGS.
[0003]
As shown in FIG. 6, between the pad 33a and the pad 33b provided on the surface of the printed wiring board 31 and maintaining the constant pitch d33 where the copper foil on the pattern 32 is exposed is soldered or removed. A short land was set up for this purpose. In FIG. 7, square pins 34a, 34b and round pins (not shown) are inserted into the mounting holes 35 provided in the pattern 32 on the printed wiring board 31 with a dedicated automatic insertion machine (not shown). The square pins 34a and 34b were short-circuited with a clip (not shown) made of a metal plate having good conductivity and energized. In addition, power was supplied by mechanical contact such as a slide switch and a toggle switch (both not shown).
[0004]
[Problems to be solved by the invention]
However, ON / OFF of the power supply or signal output line by soldering in the short land on the conventional printed wiring board may cause solder scraps and short circuit the surrounding electronic component connection circuit during the soldering operation. Many. In addition, the copper foil pattern of the short land portion is peeled off, and the electrical connection by the short land has a problem that it can be dealt with only by a soldering operation.
[0005]
There is also a means for mechanically connecting the electrical connection, which is called a slide switch or a toggle switch. Although these switches can surely turn on / off the electrical connection, there are many relatively large switches, and there is a problem that an extra space is required when mounted on a printed wiring board.
[0006]
On the other hand, in the method of mounting a plurality of square pins or round pins on a printed wiring board, there are restrictions on the automatic insertion machine. Therefore, mounting is not possible if the pitch for mounting the square pins or round pins is below a certain interval. there were. In other words, a dedicated automatic mounting machine for mounting pins is required, and automatic mounting machines that support commonly used axial and radial parts are not compatible, and the distance between pins does not fall below a certain distance. When connecting pins, there is a problem that a connection clip made of a highly conductive metal plate or the like is newly required.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a rolling part that narrows the interval at the conductive ends of a plurality of conductive pins bent into a predetermined shape, and matches the conductive pins to the standard of the automatic mounting machine. it is intended to fix and hold a resin case with a predetermined pitch.
[0008]
According to the above-described invention, the interval between the conductive pins that need to be electrically connected can be set at an arbitrary interval, and the electrical connection is not limited to a special conductive clip or the like. By utilizing the elasticity of the conductive pin, the corresponding electric circuit can be easily turned ON / OFF.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
According to the present invention, at least one of a resin case having a holding hole drilled in parallel at a predetermined interval, a conductive end protruding from the upper portion by pressing into the holding hole, and an exposed mounting leg exposed at the lower portion is different from the predetermined interval. It is composed of conductive pins that are bent so as to have an attachment interval, a rolled portion that narrows the gap between the conductive ends is provided, and a predetermined interval of the holding holes is made smaller than the attachment interval .
[0010]
In addition, the predetermined interval between the conductive pin and the holding hole in which the mounting pitch of the mounting leg matches the standard of the automatic mounting machine is made smaller than the mounting pitch.
[0012]
In addition, the mounting pitch of the mounting legs is adjusted to the standard of the automatic mounting machine, and the tip of the conductive end protruding above the resin case is a conductive pin having a shape in which the edge is eliminated.
[0013]
In addition, the conductive pin includes a conductive pin having a narrowed portion that is partially thinner than the diameter of the conductive end at a predetermined portion of the conductive end.
[0014]
Further, a part of the press-fitted portion of the conductive pin into the resin case is a narrowed portion, and the mounting leg is bent into a crank shape, and the parallel part of the mounting leg along the bottom surface of the resin case is A groove for fitting is provided in the resin case.
[0015]
A resin case having a holding hole perforated in parallel with a predetermined interval; an insulating wall in which a wall separating the lower ends of the holding hole is protruded from the bottom surface of the resin case; and a portion of the conductive end between the conductive end And a conductive portion in which one or both of the mounting legs exposed at the lower portion are bent to a mounting pitch different from the predetermined interval are pressed into the holding hole and protruded from the conductive end. Is.
[0016]
Further, the resin case is made larger than the mounting pitch of the conductive pins determined by the standard of the automatic mounting machine.
[0017]
In addition, the holding hole of the conductive pin of the resin case has a mortar shape in which the entrance from the bottom of the resin case has a wide opening, and is larger than the conductive pin diameter up to a predetermined distance, and the resin from a predetermined distance. The holding hole up to the upper side of the case has the same diameter as the conductive pin diameter or is narrowed.
[0018]
Hereinafter, embodiments of the pin header of the present invention will be described with reference to the drawings.
Example 1
1 (1) and 1 (2) are a front view and a side view of a pin header according to a first embodiment of the present invention. FIG. 2 is a sectional view thereof.
[0019]
1 and 2, a pair of conductive pins 1 bent into a predetermined shape are made of a highly insulating resin such as ABS having a holding hole 2a having a slightly narrow diameter that is the same as the predetermined shape. The case 2 is press-fitted and fixedly held.
[0020]
Further, the conductive pin 1 is provided with a throttle portion 3 that is partially processed to have a thin wire diameter at a predetermined position of the portion fixed by the resin case 2, so that the resin distortion due to press-fitting can be reduced. Since it appears as a bulge to the small diameter portion, the fitting force between the conductive pin 1 and the resin case 2 is increased, and the conductive pin 1 can be prevented from being easily detached from the resin case 2.
[0021]
In this embodiment, there are two conductive pins 1 and both are bent into a predetermined shape. However, one of the conductive pins 1 may be in a straight state without being bent into a predetermined shape. Absent.
[0022]
Moreover, by making the shape of the tip portion C of the conductive pin 1 smaller than the pin diameter r1, it is possible to prevent the conductive pins 1 from inadvertently contacting each other.
[0023]
In the present embodiment, the cross-sectional shape of the conductive pin 1 is a round pin, but a square pin may be used.
[0024]
The conductive pins 1 are fixed to the mounting pitch d1 by the resin case 2 at a 5 mm pitch or a 7.5 mm pitch determined according to the standard of the automatic mounting machine so that automatic mounting is possible. Thereby, mounting by an automatic mounting machine compatible with general radial components becomes possible.
[0025]
Further, the distance d2 between the conductive pins 1 in the distance d3 from the resin case 2 to the tip of the conductive pin 1 on the upper side is narrower than the distance d1 between the conductive pins 1 on the lower side than the resin case 2, and the conductive The flexible pins 1 are fixed and held by the resin case 2 in a parallel state with the distance d2 maintained.
[0026]
As a result, the conductive pins 1 can be easily connected to each other with a metal piece or the like from any of the A direction → ← and the B direction → ← shown in FIG. d2 can be easily soldered directly by a soldering iron, and the conductive pins 1 can be reliably connected to each other.
[0027]
(Example 2)
FIG. 3 is a front view of the pin header according to the second embodiment of the present invention.
[0028]
In FIG. 3, a rolled part is formed at a part of the conductive end of the conductive pin 1 a above the resin case 2, for example, at an intermediate part d 4 between d 5 and the root fixed by the resin case 2 from the tip of the conductive pin 1 a. 4 is provided.
[0029]
As a result, the pitch dp between the conductive pins 1a is limited in molding when molding the resin case 2. However, since the pin interval below this pitch dp can be set, the conductive pins 1a are soldered directly. When it is necessary to do so, the flow of solder is improved, good soldering is possible, and the conductive pins 1a can be reliably connected to each other.
[0030]
Further, since the distance dp between the conductive pins 1a is set narrow without directly soldering between the conductive pins 1a, the elasticity of the conductive pins 1a is utilized, and when necessary, the conductive pins 1a are used. When a light stress is applied to the gap dp to bring the conductive pins 1a into contact with each other, and the application of the stress is stopped when it is not necessary, the contact between the conductive pins 1a is released by the elasticity of the conductive pins 1a. The energized state can be easily shifted from the ON state to the OFF state.
[0031]
(Example 3)
4 (1) is a sectional view of the resin case of the pin header according to the third embodiment of the present invention, FIG. 4 (2) is a hole shape diagram for attaching the conductive pins of the resin case, and FIG. It is the figure seen from the lower surface. 4 (1), 5 is a conductive pin mounting hole for mounting the conductive pin 1a, and FIG. 4B shows a detailed view of the conductive pin mounting hole 5 for mounting the conductive pin 1a. This will be described with reference to FIGS. First, the hole diameter d7 of the predetermined section d11 in the resin case 2 protrudes upward from the resin case 2 by being the same diameter as the conductive pin 1a or slightly smaller than the diameter of the conductive pin 1a. The pitch of the conductive pins 1a can be made stable.
[0032]
In addition, the conductive pin 1a is attached to the resin case 2 from the E direction. At that time, the predetermined section d9 from the entrance is larger than the diameter of the conductive pin 1a and has a mortar shape toward the entrance. The conductive pin 1a can be easily inserted when attached.
[0033]
Further, when the conductive pin 1a is attached to the resin case 2, an inadvertent short-circuit state can be avoided by providing the contact prevention wall 6 for preventing the conductive pin 1a from contacting the lower side of the resin case 2. It becomes possible.
[0034]
Furthermore, by bending the conductive pin 1a in a crank shape, the degree of adhesion between the resin case 2 and the contact prevention wall 6 can be improved. At the same time, the fitting force can be increased and the insulation can be improved.
[0035]
The predetermined interval d11 in the resin case 2 and the interval d10 sandwiched between the predetermined interval d9 from the entrance are slightly larger than the diameter of the conductive pin 1a, so that the predetermined interval in the resin case 2 is obtained. Until the section d10, the mounting of the conductive pin 1a is smooth, and the hole diameter d7 of the predetermined section d11 in the resin case 2 is the same as the conductive pin 1a or slightly larger than the diameter of the conductive pin 1a. By making the diameter small, the pitch of the conductive pins 1a protruding upward from the resin case 2 is maintained, and a highly accurate configuration can be achieved.
[0036]
【The invention's effect】
As is clear from the above description, the following effects can be obtained according to the pin header of the present invention.
[0037]
A resin case having a holding hole drilled in parallel with a predetermined interval, and one or both of the mounting legs that are press-fitted into the holding hole and projecting the conductive end at the upper portion and exposed at the lower portion at a mounting pitch different from the predetermined interval By providing the bent conductive pins, the conductive pins can be assembled and fixed simply by press-fitting into the resin case, and the distance between the conductive ends and the mounting pitch of the mounting legs can be set freely.
[0038]
In addition, by adjusting the mounting pitch of the mounting legs to the standard of the automatic mounting machine and making the predetermined distance between the holding holes smaller than the mounting pitch, automatic assembly by the automatic mounting machine can be enabled, and the conductive pin conductive The distance between the ends can be narrower than the pitch of the mounting legs, and for example, the conductive ends by soldering can be easily short-circuited.
[0039]
In addition, the interval between the conductive pin provided with a rolled part that narrows the gap between the conductive ends in a part of the conductive end protruding above the resin case and the holding hole of the resin case for fixing the conductive pin is smaller than the mounting pitch. This makes it possible not only to set the interval between the conductive pins narrower than the pitch of the holding holes, which is restricted in molding the resin case, but also to use the elasticity of the conductive pins. Accordingly, the conductive ends can be short-circuited only by lightly applying a stress by hand, and the short-circuit between the conductive ends can be released by stopping the application of the stress.
[0040]
In addition, by making the shape of the tip of the conductive end protruding from the resin case of the conductive pin abolished, it is possible to prevent the conductive ends from inadvertently contacting each other.
[0041]
Also, the resin case has a conductive part that has a protruding part that is partially smaller than the diameter of the holding hole and a throttle part that is partially thinner than the diameter of the conductive end at a predetermined part of the conductive end. Therefore, it is possible to prevent the conductive pin from falling off the resin case, to reduce the backlash of the conductive end, and to avoid unnecessary short-circuiting between the conductive ends. .
[0042]
