    • A connector which has bellows type contacts of spring metal and a holder which has a bottom, a longitudinal slot for receiving a circuit panel, a cavity for housing the bellows type contact, a hollow formed at upper portion of the cavity and partition wall for separating the adjacent contacts. The bellows type contact consists of a lower end portion, an attached portion, a first bent portion, a second bent portion, a straight portion, a third bent portion and an upper end portion. The straight portion is the portion contacting the panel circuit. The contact has a spring substrate which consists of phosphor bronze, a contact metal of tin or tin-lead alloy, and a layer of copper between the substrate and the contact metal. With the improved shape and material of the contact, there is provided better contact performance even for a contact of tin or tin-lead alloy which is very cheap compared to the conventional gold contact and it is thus advantageous for use in consumer type electric equipment.
    • 具有弹簧金属的波纹管型触点的连接器和具有底部的保持器,用于容纳电路板的纵向槽,用于容纳波纹管型触头的空腔,形成在空腔上部的中空部分和分隔壁 相邻的接触。 波纹管型触点由下端部,安装部,第一弯曲部,第二弯曲部,直线部,第三弯曲部和上端部构成。 直线部分是接触面板电路的部分。 接触件具有由磷青铜,锡或锡铅合金的接触金属以及衬底和接触金属之间的铜层组成的弹簧衬底。 随着接触的形状和材料的改进,即使对于与常规金接触相比非常便宜的锡或锡铅合金的接触也提供了更好的接触性能,因此有利于在消费型电气设备中使用。
