    • A memory card connector includes a main body and mounted on the body for receiving a memory card therebetween. The card is insertable to a fully mated position, and the cover is mounted for movement on the body from an inoperative position to an eject position. An eject device includes a single spring mounted on the body and having a first portion. Operatively associated with the cover to bias the cover toward its inoperative position. A second portion of the single spring is operatively associated with the memory card for biasing the card in an eject direction away from its mated position.
    • 存储卡连接器包括主体并安装在主体上用于在其间接收存储卡。 卡可插入完全配合的位置,并且盖被安装成用于在从不工作的位置到排出位置的身体上移动。 弹出装置包括安装在主体上并具有第一部分的单个弹簧。 操作地与盖相关联以将盖偏置到其不工作位置。 单个弹簧的第二部分与存储卡可操作地相关联,用于使排出方向上的卡偏离其配合位置。

    • An intermediate connector for engaging a surface mount connector and a cable connector contains conductive terminals in a body portion. The body portion is cooperatively defined by distinct and separate terminal contact support portions that are affixed to opposite ends of the connector terminals. The support portions may be affixed to the connector terminals from different directions and thus eliminates the need for a complex, molded connector housing. The support portions and the terminals are held together and aligned together by a retainer and a spacer is provided to maintain a desired spacing between the terminals of the connector.
    • 用于接合表面安装连接器和电缆连接器的中间连接器包括主体部分中的导电端子。 主体部分由固定到连接器端子的相对端的不同且分开的端子触头支撑部分协作地限定。 支撑部分可以从不同方向固定到连接器端子,因此不需要复杂的模制连接器壳体。 支撑部分和端子被保持在一起并且通过保持器对齐在一起,并且设置间隔件以保持连接器的端子之间的期望间隔。
