Patent ID: 7744290

Claim:
An optical fiber connector comprising a connector housing having a splice assembly therein, for abutting an end surface of a plain fiber portion, obtained by removing an outer cover and a multi-layered inner cover from an optical fiber cable, to an end surface of a mating plain fiber portion and optically connecting plain fiber portions to each other, and an end cap, attached to one end of said connector housing, from which a primary coating portion, obtained by removing the outer cover of said optical fiber cable while leaving the inner cover thereof, is led out, wherein a boundary formed on said primary coating portion, between a portion of said primary coating portion, obtained by removing an outer coating while leaving an inner coating of the inner cover, and a portion leaving the outer coating of the inner cover, is located in an interior of said connector housing, wherein said end cap is provided in the interior thereof with a tubular portion and an extension extending from an end of said tubular portion, said tubular portion including an insert hole for an insertion of said primary coating portion approximately coaxially with a guiding hole formed in said splice assembly accommodated in said connector housing for guiding said primary coating portion leading out from said splice assembly, said extension including a strain-control hole, communicating with said insert hole, for receiving said boundary of said primary coating portion, and for controlling stress at said boundary.
