Abstract: The plug shell and receptacle of an electrical connector have registration keys and keyways that are alignable in a single rotational position. A coupling ring mounted for rotation on a plug shell has a mating set of keys and keyways that must be aligned with the registration elements of the plug shell and receptacle for insertion of the receptacle into the plug shell. After such insertion has been accomplished, the coupling ring is rotated to further draw the receptacle and plug shell together and to prevent axial separation of the plug shell and receptacle. In order to positively prevent precocking of the coupling ring prior to insertion of the receptacle into the plug shell, a locking finger is resiliently pivoted to the plug shell, having one part entering a locking recess of the coupling ring and a second part entering the plug shell bore into which the receptacle is to be inserted.

Abstract: This invention provides a filter pin connector having two capacitor disc assemblies, each with a plurality of openings receiving the connector pins and held within a connector shell. Each capacitor disc includes a plurality of laminations of conductive material formed by providing conductive ink on layers of ceramic tape which are fused together to form a unit. The laminations are in two sets and alternately arranged to provide opposed capacitor plates. The laminations of one set are connected to the pins and those of the other are connected to the shell.

Abstract: This invention provides an optical fiber connector that includes a tubular receptacle with a lens at its central portion and fiber termination units extending into its opposite ends. Each of the fiber termination units includes two elements, one telescopingly received in the other and resiliently biased toward the lens. A nut engages either end of the receptacle and the outer element of the fiber termination unit, biasing the latter element against a positive stop which limits its axial travel toward the lens. A single seal at each nut engages the receptacle and the fiber termination unit to preclude entry of foreign matter. The fibers are gripped by resilient members compressed around the fibers by crimped portions of the fiber holding units. An elongated tool, with spaced shoulders, positions the lens and its retention springs at the center of the receptacle.

Abstract: The present apparatus and method make it extremely easy for a worker, even when located in a manhole or on a telephone pole, to rapidly achieve a perfect break in an optical fiber and at a precisely predetermined position relative to a connector means. The breaking is the same, regardless of the upright, inverted or inclined position of the tool. Only a single motion of the blade is required at any desired speed, and there is no necessity for the blade to contact the fiber at a pressure within certain limits. These and other major results are obtained by clamping an optical connector element to the optical fiber before breaking is effected, and then removably securing the connector element to the breaker at a precisely known position which is correlated to the location of the scoring blade and to the characteristics of the connector.

Abstract: This invention provides a light coupling device capable of selectively dividing a light signal and controlling its transmission from an emitter to receiving elements. The device includes a light-transmissive member with two pairs of opposite lens cavities for receiving light emitting and receiving devices such as optical fibers. A partial mirror is positioned between the cavities so that extensions of the axes of the cavities intersect at the partial mirror and make equal acute angles with the partial mirror. Part of the light from an emitting device in one cavity will be transmitted through the partial mirror to the opposite lens cavity while the remainder will be reflected to a third lens cavity. The fourth cavity receives none of the light. Light from each of the lens cavities will be reflected to a different lens cavity from that of any of the others, which enables various light coupling combinations to be selected. Three lens cavities may be provided in lieu of four lens cavities.

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.
