ンに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to electrical contact pins for printed circuit boards, and more particularly, electrical contact pins are inserted into holes in a printed circuit board, with the pins protruding from each side of the base to provide electrical contacts. It relates to an electrical contact pin which serves as a terminal element onto which a connector is pushed or around which a conductor wire is wound.
印刷回路盤のメッキ被覆穴に電気的端子ピンを挿入する
さいの損傷を低減するために、いくつかの種類の押込み
嵌合ピンがすでに提案されてきた。Several types of push-fit pins have been proposed to reduce damage when inserting electrical terminal pins into plated holes in printed circuit boards.
前記ピンの装着部分は、例えば１９７４年１月１日付で
特許された米国特許第３．７８３，４３３号に示される
ように、挿入時に弾性変形される。The mounting portion of the pin is elastically deformed upon insertion, as shown, for example, in U.S. Pat. No. 3,783,433, issued January 1, 1974.
外側に曲げられかつ穴への挿入時に弾性変形される２箇
の脚をつくるように縦軸にそって装着部分を分割するこ
とは知られている。It is known to divide the mounting part along the longitudinal axis to create two legs that are bent outwards and are elastically deformed upon insertion into the hole.
この場合、ピンの挿入および保持力が２つの接触点だけ
で作用することがわかった。直接の電気的接触は、ピン
に加えられる力がメッキ被覆穴の包囲材料に伝達される
これら２つの接触点につくられる。In this case it was found that the pin insertion and retention forces act at only two contact points. Direct electrical contact is made at these two contact points where the force applied to the pin is transmitted to the surrounding material of the plated hole.
接触表面は非常に小さいので、前記の包囲材料に加えら

の材料に有害な影響を与える。さらに、前記の割り型三
脚ピンは挿入されたとき、ピンをねじったり不整合にす
る非対称断面形状を通常はしている。Since the contact surfaces are very small, the local stresses exerted on the surrounding material are high and have a detrimental effect on the material at these contact points. Furthermore, the split tripod pins described above typically have an asymmetrical cross-sectional shape that causes the pin to twist or become misaligned when inserted.
ピンはまた、１９７８年１月３日付で特許された米国特
許第４，０６６．３２６号に開示されているような３箇
の弾性脚を有するように製造される。The pin is also manufactured with three resilient legs as disclosed in U.S. Pat. No. 4,066.326, issued January 3, 1978.
この場合、これらの脚は印刷回路盤の穴にピンを挿入し
たさいに対称形状にはなってはいるが、３つの接触点だ
けがつくられ、それらの脚が恒久的な反作用を発生させ
るように互いに作用はしな℃１゜
印刷回路盤へのピンの装着面積は貴金属層（Ａｕ。In this case, these legs are symmetrical when the pin is inserted into the hole in the printed circuit board, but only three points of contact are created and the legs are designed to create a permanent reaction. The mounting area of the pin on the printed circuit board is a precious metal layer (Au).

It has been found that lateral effects occur in special applications where the coating is coated by plating (&-lead).

わたって延びるような状態で外層の被覆剥れを生じ、ま
た、好ましくない接触を生じる。Insertion of a solder-plated pin into a plated trough hole causes stripping of the outer layer and undesirable contact with the deposit extending some distance from the hole. .

けされる。Based on the thickness of the solder plating, the pin is used in two special embodiments. In the first embodiment,
The pin mounting area is coated with a thin solder layer (5-10μ). In this case, the contact pins provided on the printed circuit board are soldered by heating with or without a separate solder.

剥れは第Ｊ実施例の場合よりも小さいが、しかし、パネ
ルを振動させたさいにその剥れがピンから分離され、こ
れによって好ましくない短絡を生じる。Due to the large contact area between the pin and the hole, the solder material is stripped off during insertion, and the solder feathers on the free side of the pin and the inner surface of the hole flow together during the soldering process. In the second embodiment, the thickness of the solder layer on the mounting part of the pin is less critical, being 1-3μ, to ensure a dry connection with the hole in the printed circuit board. The peeling is smaller than in the J embodiment, but when the panel is vibrated, the peeling separates from the pins, thereby causing an undesirable short circuit.
剥れの形成は、３箇の弾性脚のうちの内側脚の外側と穴
の内側との間の大きな接触面積において重要になる。Separation formation becomes important at large contact areas between the outside of the inner leg of the three elastic legs and the inside of the hole.
