Abstract
Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は、リベット型接点の改良に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to improvements in rivet-type contacts.
（従来の技術）
リベット型接点は、一般に貴金属又は貴金属合金の無垢
の接点であるが、近年貴金属の使用量を少なくする為に
、頭部上側に貴金属又は貴金属合金の接点材を配し、頭
部下側及び脚部にＣｕを配したクラッドの接点が使用さ
れている。(Prior art) Rivet-type contacts are generally solid contacts made of precious metals or precious metal alloys, but in recent years, in order to reduce the amount of precious metals used, a contact material made of precious metals or precious metal alloys is arranged on the upper side of the head. Clad contacts with Cu on the lower side and legs are used.
（発明が解決しようとする課題）
ところで、無垢のリベット型接点もクラッドのリベット
型接点も共に接点材は、接点線材を所要の長さに切断し
、無垢の場合は直ちにリベット型に予備成形し、然る後
所要のリベット型に仕上げ成形し、クラッドの場合は所
要の長さに切断した接点材を、ベース線材を所要の長さ
に切断して得たベース材に圧接すると同時にリベット型
に予備成形し、然る後所要のリベット型に仕上げ成形し
ていたが、頭部の厚さが薄い場合、もしくは増面率が高
い場合、頭部の下側周囲に割れが発生し易く、また楕円
状に成形され、ぼり等が発生するという問題があった。(Problem to be Solved by the Invention) By the way, the contact material for both solid rivet type contacts and clad rivet type contacts is obtained by cutting the contact wire material to the required length, and in the case of solid material, immediately preforming it into a rivet type. After that, it is finished formed into the required rivet mold, and in the case of cladding, the contact material cut to the required length is pressed against the base material obtained by cutting the base wire material to the required length, and at the same time it is formed into the rivet mold. It was preformed and then finished formed into the required rivet shape, but if the thickness of the head is thin or the area increase rate is high, cracks tend to occur around the bottom of the head. There was a problem in that it was formed into an elliptical shape, causing burrs and the like.
特に接点材が焼結合金より成る場合は、頭部の厚さが薄
い場合、増面率が高い場合に成形時に割れが発生した。In particular, when the contact material is made of a sintered alloy, cracks occur during molding when the thickness of the head is thin or when the area increase rate is high.
一方、割れを防止する為に、頭部の厚さを厚くし、増面
率を低くすると、接点材とベース材との接合強度が低く
なるものである。On the other hand, if the thickness of the head is increased and the area increase rate is decreased in order to prevent cracking, the bonding strength between the contact material and the base material will decrease.
そこで本発明は、ばね材の接点取付穴に挿入し、かしめ
止めした際、かしめ量を少なくして、増面率を低くする
事にて割れが発生せず、また楕円状成形やばりが生ぜず
、しかも十分な接点材とベース材の接合強度を有するリ
ベット型接点を提供しようとするものである。Therefore, when the spring material is inserted into the contact mounting hole and caulked, the present invention reduces the amount of caulking and lowers the area increase rate, thereby preventing cracking and preventing elliptical formation and burrs. First, it is an object of the present invention to provide a rivet type contact having sufficient bonding strength between the contact material and the base material.
（！ｌｌｔ！を解決するための手段）
上記課題を解決するための本発明のリベット型接点は、
頭部をベース材となし、脚部及び頭部下面中央の脚部の
付け根を接点材となしたことを特徴とするものである。(Means for solving !llt!) The rivet type contact of the present invention for solving the above problems is as follows:
The head is a base material, and the legs and the base of the legs at the center of the lower surface of the head are contact materials.
（作用）
上記の如く構成されたリベット型接点は、ばね材の接点
取付穴に接点材の脚部を挿入し、接点取付穴の周縁にか
しめ止めすると、接点材の脚部の増面率が低いので、割
れが発生しないものである。(Function) In the rivet type contact configured as described above, when the leg of the contact material is inserted into the contact mounting hole of the spring material and caulked to the periphery of the contact mounting hole, the area increase rate of the leg of the contact material increases. Since it is low, cracks do not occur.
また増面率が低い為、接点材が楕円状に成形されること
も無く、接点材の周縁にばつが生じることも無い。In addition, since the area increase rate is low, the contact material is not formed into an elliptical shape, and no burrs occur on the periphery of the contact material.

A contact wire made of 11.7% n02 with a length of 0.85au
Contact material 1 obtained by cutting into g, diameter 1.9fl]Ill
The base material 2 obtained by cutting a base wire made of Cu into a length of 0.7+nIl was cold-welded to the base material 2 as shown in Figure 1, and at the same time, the base material 2 was turned into a ribbed/ ) shape with the base material 2 side as the head. After preforming, the head diameter is 3.5 m as shown in Figure 1C.

．． It was finished and molded into a 5mm rivet mold.

１′に成形した。The rivet type contact 3 of the embodiment thus manufactured was heat treated and polished to a width of 12 mm as shown in FIG. 2a.
The leg of the contact material 1 of the rivet type contact 3 is placed upward in the contact mounting hole 5 with a diameter of 2.0 mm at the tip of the spring material 4 made of phosphor bronze with a thickness of 0.15w and a length of 30 mm as shown in Fig. 2. The leg portion of the contact material 1 is caulked to the periphery of the contact mounting hole 5 as shown in FIG. 2C, and the diameter is 2. '! m
The contact material 1' was molded into a circular arc surface with a top surface of 8 mmH and a thickness of 0.3 mm.
こうしてかしめ止めして成形された接点材１′は、熱処
理（アニール）された接点材１は、増面率が低いので、
割れが全く発生しなかった。また増面率が低い為、接点
材１′が楕円状に成形されず、円形で、しかも周縁に全
くばつが生じなかった。The contact material 1' formed by caulking in this manner is heat-treated (annealed) because the area increase rate is low.
No cracking occurred. Further, since the area increase rate was low, the contact material 1' was not formed into an elliptical shape, but was circular, and there was no flaw in the periphery.
一般にＣｕの据込加工に於いては、径の１．８倍以上の

った。In general, when upsetting Cu, buckling occurs if the length is 1.8 times the diameter or more, but the contact material 1 has an expanded diameter of 2.0 + nm and a leg length of 0.0 nm. Since the thickness was 1.8 times or less as described above at 5 inches, there was no concern that buckling would occur at all.

When the contact material is stopped, the area increase rate of the contact material is low, so there is no cracking, no elliptical formation, and no burrs.
