Abstract: This invention provides a connector for optical fibers which includes a receptacle within which is a lens member, with plugs being connected to the opposite ends of the receptacle so that optical fibers carried by the two plugs are in a light-transmissive relationship at the lens member. The plugs include forward tapered surfaces which are biased by resilient forces against tapered surfaces of the lens member for directly aligning the plugs with the lens member. Each of the plugs includes a back shell carrying a clamping member in which resilient pads are biased against the fiber to grip it without damaging it. Within the front shell the optical fiber is caused to bow in a predetermined direction which enables compensation to be made for any offset in the axes of the cavities in the lens member.

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: 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.
