Abstract: This invention provides an optical fiber connector in which axially aligned, inwardly tapering openings are provided in opposite sides of a member and interconnected at their inner ends, a quantity of matching optical fluid is positioned within the openings and cylindrical optical fibers are pressed axially into the openings so that their end corners engage the tapered walls of the openings to align the fibers and position their end faces in close adjacency. The fibers displace some of the optical fluid as they enter the openings so that the fluid occupies the space between their end faces. The fiber alignment principle may be used as well in connecting a fiber to a light source or a fiber to a detector.

Abstract: This invention provides an arrangement for optical coupling, including interconnecting optical fibers, coupling a source to the fiber and coupling a fiber to a detector. The connector may comprise an objective lens and an immersion lens provided by opposed cavities in a transparent medium, each containing an index of refraction material, with the optical fibers to be connected inserted into the opposed cavities. Cavities also are used in source-to-fiber and fiber-to-detector coupling, being defined by surfaces of revolution and providing an aligning and positioning means. By appropriate selection of the indices of refraction of the index of refraction material and the transparent medium, the light from the emitting device is refracted and transmitted to the receiving device, resulting in low-loss light transmission. Means may be provided for changing the emittance angle so as to cause the light to be within the acceptance angle of the receiving device.

Abstract: An electrical connector arrangement including individual modules which may be assembled in a side-by-side relationship in a supporting device having spaced, opposed, inwardly inclined resilient spring fingers engageable with shoulders on the modules for holding them in place, each module including a dielectric body having cavities therein within which are pin contacts that enter socket contacts at the ends of wires inserted into the cavities. An optional lateral wire support attachment has flanges fitting within grooves in the sides of the modules. The modules are removable from the support rail by a bifurcated tool which pries the resilient fingers outwardly to free the modules, the same tool being usable to deflect the flanges of the wire support away from the grooves and allow removal of that component.

Abstract: This invention provides a connector for optical fibers which includes two connector sections each of which has a means for holding an optical fiber, one of the sections having an inclined surface engaged by the end portions of both of the fibers where their end faces abut. One of the fibers is bent to its position of engagement with the inclined surface as held in one section of the connector. The other of the optical fiber is bent by the inclined surface as the two connector sections are brought together to a mated position.

Abstract: An arrangement for forming an electrical connection to a thin, deflectable conductor, such as in a printed circuit tape, in which a pin is forced through an opening in the conductor to expand the opening to cause the conductor to overlie and bear against the surface of the pin, the conductor being held between dielectric members adjacent the pin to limit the part deflected. Adapters allow a single pin assembly to engage several tapes, while the pins may have ends that either directly engage conventional socket contacts or intermediate contacts which, in turn, mate with conventional contacts connected to wires.

Abstract: A connector for optical fibers including in each connector section a shell containing a ferrule having an opening receiving a plurality of optical fibers positioned in abutting relationship in predetermined locations, one of the connector sections including a rotatable member coupled to the other connector section for selectively rotationally adjusting the positions of the mating connector sections so as to optimize alignment of individual glass fibers in the two connector sections. The optical fibers of each connector section are assembled in the ferrule and shell before being finished to present a collective flat perpendicular end surface at a predetermined location.
