Abstract: A safety adaptor for a male electrical connector housing having at least one male terminal is provided. A body member having a space therein of a configuration to receive the electrical connector housing while operatively supporting a cantilevering of the male terminal from the body member is utilized. A cover member can be flexibly linked to the body member for locking the safety adaptor to the electrical connector housing. A pair of parallel prongs can extend from the body member and can be positioned for limiting the size of a complementary female connector capable of operatively receiving the male terminal member.

Abstract: An electrical connector device comprising male and female housings and terminal seating detecting means. Each of the housings includes retaining means protruding in the form of a cantilever from each of partition walls, which define terminal chambers arranged in the form of a matrix composed of a plurality of rows and columns, and resiliently bendable in a flexure space. As male terminals, contained individually in the terminal chambers, and female terminals, adapted to be connected to the male terminals, engage the retaining means, the terminals are prevented from slipping out of the chambers. The terminal seating detecting means is fitted into the flexure space of the retaining means when the terminals are contained in their corresponding terminal chambers so that they normally engage the retaining means.

The module is detachably mounted to the support members such that the electrical connectors are aligned with and coupled to the electrical leads on the printed circuit cards in the mainframe card cage when the arms are moved from a first position to a second position.

Abstract: A vacuum tight electrical feedthru is disclosed for use where electrical leads must pass through the walls of a container in which a high vacuum must be maintained. It is useful in conjunction with infrared sensors, as well as for security, fire detection, rescue, night vision and medical applications. The feedthru includes a ceramic circuit ring with electrical traces deposited on one side. A ceramic seal ring partially covers the traces and is fired down to the main ceramic ring forming a hermetic seal. Metal rings are brazed to the seal ring and the ceramic circuit ring to allow welding to a housing. Spring loaded pads load a resilient pad onto the cables forcing gold plated dots to make contact to the pads on the ceramic circuit ring. This feedthru provides 180 conductors, 90 on each side. The ribbon cables are etched to expose the wires, which are then pressed on the gold dots.
