    • A memory cartridge for convenient manual attachment of a RAM memory with battery back-up to an I/O module in a programmable controller system is inserted through an opening in a side cover of the I/O module and connected to a main circuit board. The housing has a pair of clip members on opposite ends with grooves running transversely across the ends to receive the edges of mounting flanges extending inward at upper and lower ends of an opening in the side cover. The clip members are yieldable in the longitudinal direction of the cartridge housing--to squeezed between a thumb and fingers of one hand--and when the cartridge is inserted through the side cover opening to a certain depth, the clip members are released to secure the cartridge between the mounting flanges.

    • A protective package for use with a printed circuit board having mounted thereon at least one semiconductive device susceptible to deleterious effects of variance of potential across the terminals of the device or the presence of static electric discharges. The package provides, in one embodiment, a single piece, insulating case supporting and enclosing the entire circuit board and its components and a shorting member having integrally formed, spring biased contact fingers in normal engagement with the termination pads of the board. The contact fingers are separable from engagement with the termination pads upon insertion of the circuit board into an edge connector. Another illustrated embodiment provides a holder or support for a shorting member which may enclose only a portion of a printed circuit board and only a portion including termination pads.
    • 一种与印刷电路板一起使用的保护性封装件,其上安装有至少一个半导体器件,易受器件端子上的电位变化的有害影响或静电放电的影响。 该封装在一个实施例中提供了一个单件绝缘壳体,其支撑和封闭整个电路板及其部件,以及具有与板的端接垫正常接合的具有整体形成的弹簧偏置接触指的短路构件。 当将电路板插入到边缘连接器中时,接触指与分离垫不会接合。 另一示例性实施例提供了一种用于短路构件的保持器或支撑件,其可以仅包围印刷电路板的一部分,并且仅包括包括端接垫的部分。
