D-2245 OPTICAL CABLE CONNECTOR ABSTRACT OF THE DISCLOSURE An optical cable connector includes a fiber connector plug and a mating connector receptacle. The plug, which receives an assembly including sheath and optical fiber, includes a generally cylin- drical optical pin, a compression spring, a spring retainer nut, and a pin housing. The pin has an axial passageway including a large portion for receiving the assembly, and a small portion for receiving the fiber. The pin has a nominal outer diameter with a medial circular flange. The inner diameter of the spring is sufficient to receive the pin nominal outer diameter but not the flange. The nut has an inner passageway with a diameter greater than the nominal outer diameter, hut smaller than the flange. The nut has an external male thread. The pin housing has an axial passageway having an internal female threaded end portion which engages with the nut external thread, a medial portion which receives the pin with its medial flange for axial reciprocation therewithin, and an opposing end portion which is sufficient to receive the nominal outer diameter but not the flange. The mating connector receptacle includes a housing, a circular shim, a photodiode housing assembly, and a retainer cap. The housing includes an outer cylindrical shell, a flanged base, a photodiode chip affixed to the base, electrical leads extending through the base to the chip, and a transparent light pipe affixed to the chip and extending axially with the shell, the light pipe having a diameter substantially larger than the diameter of the fiber. The shim has a central hole. The photodiode housing assembly, which has an outer thread, has an axial passageway having a medial portion D-22245 -15- large enough for the nominal outer diameter portion of the pin to reciprocate therewithin, a first tapered end portion for engaging the medial portion, and an opposing larger end portion for receiving the shim and a substantial portion of the outer cylindrical shell of the housing, but not the base. The cap has an inner thread adapted to engage with the outer thread of the photodiode housing assembly and has an inner portion adapted to engage the flanged base of the housing.
