Abstract: A plug-in interconnection for optical and avioptic cables for connecting those cables into equipment such as circuit boards having fiber optic circuitry running in a plane normal to the axis of the plug-in interconnection. In the interconnection, a male connector having the end of the optical fiber means of the cable projecting from the end thereof is plugged into an on-axis female receptacle. In the receptacle, an aperture normal to its axis receives either the end or light from the end of the optical fiber circuit means in the equipment being interconnected. Reflecting means in the bore of the female receptacle aligned with the axis of optical fiber means in the male plug-in connector, when plugged in, reflects light signals between the optical fiber means in the connector and the circuit means in the equipment. An embodiment in which the light signal reflecting means is in the male connector is also disclosed.

Abstract: A circuit card having the capability for the high-density packaging of electronic components thereon for use in high power-density card racks in computer and other electronic and avionic systems. The card has an all metal construction with an elongated planar body portion for the mounting of electronic components on the opposite sides thereof and has a heat pipe located along the edges of one elongated side and the two ends. A connector for making the required electrical connections to the electronic components is provided along the edge of the second elongated side. Edge tabs on the ends of the card permit the card to be installed into a card rack in electronic equipment. The elongated portion of the heat pipe serves as the evaporator region thereof and the two end portions act as the condensing regions.
