【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、コンピュータ等の電子機器に使用される小型
コネクタに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a small connector used in electronic equipment such as computers.
従来のコネクタの接触子は、１対の接触部分が雌雄構造
をなして、非対称構造でなるものが多い。Many of the contacts of conventional connectors have an asymmetrical structure, with a pair of contact portions having a male and female structure.
また、１対の接触部分を、対称構造としたものには、第
３図に示すようなものがある。Further, there is a structure in which a pair of contact portions have a symmetrical structure as shown in FIG.
これは、１対の接触子（Ａ）（Ａ）は、弾性変形の生じ
難い角柱状の基部導体（Ｂ）と、接触部を弧状になして
、弧面を角柱の１側方に向けた接点部（Ｃ）と、基部導
体（Ｂ）と接点部（Ｃ）の間にあって、接点部（Ｃ）に
弾性変形を与えるために、基部導体（Ｂ）の断面積より
も断面積を小としたバネ部（Ｄ）とからなっている。This is because a pair of contacts (A) (A) is connected to a prismatic base conductor (B) that is unlikely to undergo elastic deformation, and the contact portion is in an arc shape, with the arc surface facing one side of the prism. The contact part (C) is located between the base conductor (B) and the contact part (C), and has a cross-sectional area smaller than that of the base conductor (B) in order to give elastic deformation to the contact part (C). It consists of a spring part (D).
最近の電子装置は、高密度化され、それに伴い。 Recent electronic devices have become denser and accordingly.
コネクタの形状も、一般的な２．５４ｍピッチのものに
比して、ｌ／２ピツチとしたハーフサイズのものが要求
されている。The shape of the connector is also required to be half-sized, 1/2 pitch, compared to the general 2.54 m pitch.
ハーフサイズのコネクタは、端子間ピッチが標準ピッチ
（２，５４ｍ）の半分（１，２７ｍ）になるとともに。For half-size connectors, the pitch between terminals is half (1.27 m) of the standard pitch (2.54 m).
コネクタの軸線方向の断面積が標準サイズの１７４にな
り、大幅に小形化される。The axial cross-sectional area of the connector is 174 mm, which is the standard size, making it significantly smaller.
端子間ピッチがハーフサイズになると、従来の雌雄１対
式の接触子構造は、単に形状を小さくするだけでは、コ
ネクタとして機能しなくなるものがあり、また、接触子
の形状を小さくすることが不可能なものもある。When the pitch between terminals becomes half size, the conventional one-male and one-male contact structure may no longer function as a connector simply by making the shape smaller, and it is also impossible to make the contact smaller. Some things are possible.
特に、雌側の接触子は、雄側の接触子に比較して、小さ
くすることが困難である。In particular, it is difficult to make the female contact smaller than the male contact.
標準サイズのコネクタの各寸法を、全体に１７２にして
ハーフサイズのコネクタを形成する場合、各接触子の組
み立てや、組付けの容易性、及び組み立て精度に問題が
ある。When forming a half-sized connector by changing the dimensions of a standard-sized connector to 172, there are problems with the assembly of each contact, the ease of assembly, and the accuracy of assembly.
さらに、第３図に示すように、１対の接触子が同一構造
のものには、以下のような問題点がある。Furthermore, as shown in FIG. 3, a pair of contacts having the same structure has the following problems.
図示のような接触子（Ａ）（Ａ）を加工するには、平板
材から打ち抜き加工するのが、最も容易で安価な方法で
ある。To process the contacts (A) (A) as shown, the easiest and cheapest method is to punch them from a flat plate.
しかし、小形の接触子（Ａ）（Ａ）に使用される導電性
弾性材は、ベリリューム鋼等の高価な材料であるため、
抜き加工では、多くの切屑を出して、材料の利用率が低
くなり、接触子（Ａ）の価格は高価となる。However, since the conductive elastic material used for the small contactor (A) (A) is an expensive material such as beryllium steel,
In the punching process, a lot of chips are produced, the utilization rate of the material is low, and the price of the contact (A) is high.
本発明においては、断面が円形をなす棒状の弾性電導体
の端部近くに、該電導体を軸線方向に圧縮して、直径を
径方向に膨出させた、拡径接触部を形成するとともに、
この拡径接触部を備えた弾性電導体１対を、拡径接触部
が設けられた端部を向き合せ、かつ一方の拡径接触部が
他方の弾性電導体の基部外周面に接するように、相互の
軸線を若干偏らせて、端部同士を重ね合わせることによ
り、上述の課題は解決される。In the present invention, near the end of a rod-shaped elastic conductor having a circular cross section, an enlarged diameter contact portion is formed by compressing the conductor in the axial direction and expanding the diameter in the radial direction. ,
A pair of elastic conductors each having an expanded diameter contact portion are arranged so that the ends provided with the expanded diameter contact portion face each other, and one expanded diameter contact portion is in contact with the outer peripheral surface of the base of the other elastic conductor. The above-mentioned problem can be solved by overlapping the ends with their mutual axes slightly deviated.
基部導体の直径よりも拡径された接触部が、互いに相手
側の基部導体の外周に弾性的に圧接し、その際の弾性力
は、互いの基部導体の軸線に対して、相互に求心的に働
き、確実な接触を、２個所の拡径接触部と基部導体間で
得ることができる。The contact parts whose diameter is larger than the diameter of the base conductor are elastically pressed against the outer periphery of the base conductor on the other side, and the elastic force at that time is mutually centripetal with respect to the axis of the base conductor. A reliable contact can be obtained between the two enlarged diameter contact portions and the base conductor.
