本発明は、電気接点材料に係り、特にＡｇ−Ｃｄ０より
成る電気接点材料の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to electrical contact materials, and particularly to improvements in electrical contact materials made of Ag-Cd0.
Ａｇ−Ｃｄ０より成る電気接点材料は、継電器の接触力
、開離力の大きい場合、耐溶着性に優れ、接触抵抗が安
定している為、広く多用されている。Electrical contact materials made of Ag-Cd0 are widely used because they have excellent adhesion resistance and stable contact resistance when the contact force and separation force of relays are large.
昨今、継電器の小型化に伴い接触力、開離力の低下、接
点の小型化、接点ギャップの狭小化に伴い耐溶着性に問
題が生じてきた。この為、耐溶着性に優れた電気接点材
が要望されている。Recently, as relays have become smaller, contact force and separation force have decreased, contacts have become smaller, and contact gaps have become narrower, resulting in problems with welding resistance. For this reason, there is a demand for electrical contact materials with excellent welding resistance.

は耐アーク性。The reason why the component composition of the electrical contact materials of the present invention is limited as described above is as follows.As is well known, Cd is necessary for maintaining excellent welding resistance and stable contact resistance, and Cd is necessary for maintaining excellent welding resistance and stable contact resistance. If the amount is less than 1%, good welding resistance cannot be obtained, and if it exceeds 20% by weight, the abrasion resistance deteriorates even if elements that improve the abrasion resistance are added.
0 to 20% by weight is preferred. Mn is for welding resistance -L
It is necessary for Since it cannot be suppressed by adding Bi, which will be described later, 0.5 to 5
City plastic% is preferred. 'I''e is necessary for improving sublimation drop welding resistance when the oxide opens and closes the contact, and if it is less than 0.5% by weight, it has no effect, and if it exceeds 5% by weight, the wear resistance deteriorates. , 0.5 to 5% by weight is suitable.1
In the case of 3i, the oxide is brittle and easily decomposed, so it improves the welding resistance when the contact force and separation force are small, and the Mn oxide precipitates in a 1-like form during internal oxidation, resulting in poor contact resistance and temperature- Necessary to prevent the rise in temperature from increasing, 0.1% by weight.
If it is not 11ζ, it will not have this effect, and if it exceeds 3% by weight, the melting point of the alloy will be extremely lowered and internal oxidation at high temperature will become impossible, so 0.1 to 3% by weight is preferable. Fe group elements are arc resistant.

A contact opening/closing test was conducted under the following test conditions using a fixed contact with a thickness of 1 mm and a movable contact with a straight line of 1 line and 4 lines, a thickness of 1.1 mm, and 5H, and the results were shown in the right column of the table below. The results were as shown in iυ.

The electrical contact made of the electrical contact material No. 7 has a higher number of openings and closings before welding occurs than the electrical contact made of the electrical contact material No. 7, and has excellent welding resistance, and has an equally low contact resistance. Moreover, it can be seen that the variation is small and stable. It can be seen that the arc consumption of the electrical contacts made of the electrical contact material H of Examples 1 to 7 is equal to or less than that of the electrical contacts made of the electrical contact material of Conventional Examples 1.2.

It has a stable contact resistance equivalent to that of the conventional electrical contact material made of Ag-Cd0, and has significantly improved melting foil resistance, so it is suitable for the electrical contact material made of conventional Ag-Cd0. It can be said to be an epoch-making product that can be replaced.
