连接器的材料通常可分为以下三种:接触面底层金属、电镀层及塑料绝缘体。用于连接器接触面底层的材料,必须有良好的弹性,能够容易地精密成形,并具有一定的抗腐蚀性和较好的电传导性。黄铜是一种具有良好电传导性的廉价材料,但不能经受多次插拨的循环作用。会因老化而逐渐失去弹性。在重复应力下,易产生晶化,因而降低导电系数。然而黄铜适用于很多非临界的小接触力的场合。此外,容易成型并可进行钎焊、焊接和锌铜合金钎 Connector materials can usually be divided into the following three: the contact surface of the underlying metal, plating and plastic insulators. The material used for the bottom layer of the contact surface of the connector must have good elasticity, can be easily formed with precision, and has certain corrosion resistance and good electrical conductivity. Brass is a cheap material with good electrical conductivity, but can not withstand the effects of multiple insert cycles. Will gradually lose its elasticity due to aging. In repeated stress, easy to produce crystallization, thus reducing the conductivity. However brass is suitable for many non-critical small contact forces. In addition, easy to shape and can be brazed, welded and zinc-copper alloy brazing
