本発明は、リベツト型複合接点の製造方法の改
良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a method for manufacturing a rivet-type composite contact.
従来、リベツト型複合接点を作るには、第１図
ａに示す複合接点条材１を所要の長さに切断して
仝図ｂに示す如き角柱状の複合接点材２を作り、
次にこの複合接点材２の上半部を圧潰して仝図ｃ
に示す如く予備成形し、次いで仝図ｄに示す如く
リベツト型に仕上げ成形して複合接点３を得てい
る。 Conventionally, in order to make a rivet type composite contact, a composite contact strip 1 shown in FIG. 1a is cut to a required length to make a prismatic composite contact material 2 as shown in FIG.
Next, the upper half of this composite contact material 2 is crushed and
The composite contact 3 is obtained by preforming as shown in FIG.
然し乍ら、かかる製造方法では複合接点材２の
切断面がひびり、これがリベツト型に仕上げ成形
した複合接点３の外周面に第２図ａに示す如く残
つてばり４となるものである。 However, in such a manufacturing method, the cut surface of the composite contact material 2 cracks, which remains as a burr 4 on the outer peripheral surface of the composite contact 3 finished into a rivet type, as shown in FIG. 2a.
これは複合接点条材１が軟らかすぎると複合接
点材２の切断面にだれ及びばりが発生する為、硬
い状態にて切断する結果切断面がひびるからに他
ならない。 This is because if the composite contact strip 1 is too soft, sag and burrs will occur on the cut surface of the composite contact material 2, and as a result of cutting in a hard state, the cut surface will crack.
また上記の製造方法では硬い状態の複合接点材
２を予備成形し、仕上げ成形することになるの
で、第２図ｂに示す如く得られるリベツト型複合
接点３の上下両面の接点金属１６の厚みが不均一
となつたり、第２図ｃに示す如くリベツト頭部３
ａとリベツト脚部３ｂが芯ずれしたりすることが
多々あつた。 In addition, in the above manufacturing method, the composite contact material 2 in a hard state is preformed and then final molded, so that the thickness of the contact metal 16 on both the upper and lower surfaces of the resulting rivet type composite contact 3 is reduced as shown in FIG. 2b. If the rivet head 3 becomes uneven, as shown in Figure 2c,
There were many cases where the center of the rivet leg 3b was misaligned with the rivet leg 3b.
本発明はかかる問題点を解消すべくなされたも
のであり、外周面にひびり跡によるばりの発生が
無く、接点金属の厚みが均一で、リベツト頭部と
リベツト脚部が芯ずれしないリベツト型複合接点
の製造方法を提供せんとするものである。 The present invention has been made to solve these problems, and provides a rivet type in which there is no burr caused by crack marks on the outer peripheral surface, the thickness of the contact metal is uniform, and the rivet head and rivet leg are not misaligned. The present invention aims to provide a method for manufacturing a composite contact.

ることを特徴とするものである。 The method for manufacturing a rivet type composite contact of the present invention involves cutting the composite contact strip 1 shown in FIG. This composite contact material 2 was placed in a non-oxidizing atmosphere.
The composite contact material 2 is heat treated at 300 to 500°C, then the upper half of the composite contact material 2 is crushed and preformed as shown in Figure c, and then finished formed into a rivet mold as shown in Figure d. It is something to do.

に於いて、予備成形前に複合接点材２を300〜500
℃で熱処理する理由は、硬い複合接点材２を或る
程度軟かくして加工し易くする為で、300℃未満
ではベース金属（Cu又はCu合金）にその効果が
現われず、500℃を超えると複合接点材２の接点
金属（Au、Ag等）同志が粘着し、またベース金
属がもろくなるからである。 In the method for manufacturing a rivet type composite contact of the present invention, the composite contact material 2 is heated to 300 to 500 ml before preforming.
The reason for heat treatment at ℃ is to soften the hard composite contact material 2 to a certain extent and make it easier to process. Below 300℃, the effect will not appear on the base metal (Cu or Cu alloy), and if it exceeds 500℃, the composite will deteriorate. This is because the contact metals (Au, Ag, etc.) of the contact material 2 stick together, and the base metal becomes brittle.
また非酸化性雰囲気中で熱処理する理由は、ベ
ース金属の酸化を防止する為である。 Further, the reason for heat treatment in a non-oxidizing atmosphere is to prevent oxidation of the base metal.
尚熱処理時間は複合接点材２の寸法、材質にも
よるが大概20〜30分で充分である。 Although the heat treatment time depends on the dimensions and material of the composite contact material 2, 20 to 30 minutes is usually sufficient.
