Definitions
- a connector terminal according to the present invention has a contact portion in electrical contact with another conductive member, a silver layer, and the silver layer in contact with a solution containing thiol and benzotriazole.
- the gist is to have a coating layer comprising a film to be formed.
- thiol is octadecanethiol
- a high lubricating effect can be imparted to the contact portion.
- the base material 1 serves as a base material for the connector terminal, and may be made of any metal material. However, the base material 1 exemplifies a case of copper or a copper alloy most commonly used as the base material of the connector terminal. be able to. Further, on the surface of the base material 1, an intermediate layer may be appropriately formed in the lower layer of the silver layer 2 for the purpose of improving the adhesion between the silver layer 2 and the base material 1 or imparting heat resistance. Good. As such an intermediate layer, a nickel layer can be exemplified, and when the base material 1 is made of copper or a copper alloy, it plays a role of preventing diffusion of copper atoms from the base material 1 to the silver layer 2.
- the silver layer 2 may be composed of either a hard silver layer or a soft silver layer. Preferably, it is a soft silver layer that has a large friction coefficient reducing effect and has low resistance and high heat resistance reliability. Silver has a relatively low resistivity among various metals, and oxidation of the surface does not proceed so much, so that it exhibits a low contact resistance value on the surface.
- the thickness of the silver layer 2 is preferably in the range of 1 to 10 ⁇ m. If it is thinner than this range, the effect of reducing the contact resistance is reduced. On the other hand, if it is thicker than this range, the friction coefficient of the surface is hardly reduced effectively even if the lubricating layer 3 is formed on the surface due to the softness of silver.
- the silver layer 2 may be formed by any method, but is preferably formed by an electrolytic plating method from the viewpoint of productivity and manufacturing cost reduction.
- the solvent forming the solution may be any solvent as long as it can dissolve thiol and benzotriazole, but water is preferably used. This is because water easily evaporates in the atmosphere, and the solvent does not remain on the terminal surface as in the case of using an organic solvent, and the handleability of the connector terminal is not lowered. Moreover, by using water as a solvent, the solution can be easily handled and discarded in the production process, and the waste liquid does not adversely affect the environment.
Abstract
Description
板状の銅合金母材の表面に、厚さ5μmの軟質銀層を電解めっき法にて形成した。この銀めっき板を、オクタデカンチオール(C18SH)とベンゾトリアゾール(BTA)の混合水溶液(ケミカル電子社製「CE9500W」)に52℃にて1分間浸漬し、取り出し後、自然乾燥させた。
実施例1と同様に作成した銀めっき板を濃度0.025%のベンゾトリアゾール水溶液に52℃にて1分間浸漬し、取り出し後、自然乾燥させた。
実施例1と同様に作成した銀めっき板を濃度1mMのオクタデカンチオール水溶液に52℃にて1分間浸漬し、取り出し後、エタノールを用いて洗浄し、乾燥させた。
(摩擦係数の評価)
端子の挿入力の指標として、実施例1及び比較例1、2にかかる試料片について、動摩擦係数を評価した。つまり、平板状の試料片と半径3mmのエンボス状にした試料片を鉛直方向に接触させて保持し、ピエゾアクチュエータを用いて鉛直方向に5Nの荷重を印加しながら、10mm/min.の速度でエンボス状のめっき部材を水平方向に引張り、ロードセルを使用して(動)摩擦力を測定した。摩擦力を荷重で割った値を摩擦係数とした。各試料片について、5回の独立した測定を行った。
飛行時間型二次イオン質量分析法(TOF-SIMS)を用いて、実施例1及び比較例2にかかる試料片について、表面に存在する化学種の分析を行った。
表1に、各試料片についての摩擦係数の測定結果を示す。
