Abstract
Abstract An optical fiber connection apparatus includes a pair of mating connector halves each accommodating at least one optical fiber. A plug half is insertable into a receptacle half to provide optical connection between the fibers therein. The receptacle portion includes a movable cover supported thereon. The cover is movable from a first position covering the receptale and thereby protecting the fiber therein to a second position opening the receptacle to allow for insertion of the plug. The cover is also movable to lock the plug into the receptacle.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
331 words
A connection apparatus for mechanically and optically connecting optical cables comprising: an elongate receptacle including a first end for accommodating a first optical cable, an open second end and a pair of side walls between said first and second ends defining a channel for interconnection access to said receptacle, each said side wall further including a projection extending therefrom, adjacent said open second end; an elongate plug including a first end for accommodating a second optical cable and a second end being insertable into said channel of said receptacle to place said first and second cables in optical connection; a cover moveably supported on said receptacle adjacent said open second end of said receptacle, said cover including a cover surface for covering said open second end of said receptacle and depending mounting surfaces each disposed in contact with one of said side walls of said receptacle, each mounting surface including an L-shaped guideway therein which accommodates one of said projections of said side walls of said receptacle for providing moveable support of said cover relative to said receptacle, said cover being moveable from a first position wherein said cover surface covers said open second end of said receptacle to a second position uncovering said open second end of said receptacle thereby rendering accessible said channel for optical connection of said first and second cables and further being moveable to a third position in locking engagement with said plug to thereby lock said plug in said channel of said receptacle, said cover being moveable among said three positions by movement of said cover along said L-shaped guideways about said projections, said mounting surfaces being formed of resiliently deformable material such that upon application of an external force to said plug when said cover is in said third position, said force is transferred to said mounting surfaces thereby causing resilient deformation of said mounting surfaces and disengagement of said projections from said guideways, placing said cover out of locking engagement with said plug.
Claim 2
Dependent Claim
331 words
A connection apparatus for mechanically and optically connecting optical cables comprising: an elongate receptacle including a first end for accommodating a first optical cable, an open second end and a pair of side walls between said first and second ends defining a channel for interconnection access to said receptacle, each said side wall further including a projection extending therefrom, adjacent said open second end; an elongate plug including a first end for accommodating a second optical cable and a second end being insertable into said channel of said receptacle to place said first and second cables in optical connection; a cover moveably supported on said receptacle adjacent said open second end of said receptacle, said cover including a cover surface for covering said open second end of said receptacle and depending mounting surfaces each disposed in contact with one of said side walls of said receptacle, each mounting surface including an L-shaped guideway therein which accommodates one of said projections of said side walls of said receptacle for providing moveable support of said cover relative to said receptacle, said cover being moveable from a first position wherein said cover surface covers said open second end of said receptacle to a second position uncovering said open second end of said receptacle thereby rendering accessible said channel for optical connection of said first and second cables and further being moveable to a third position in locking engagement with said plug to thereby lock said plug in said channel of said receptacle, said cover being moveable among said three positions by movement of said cover along said L-shaped guideways about said projections, said mounting surfaces being formed of resiliently deformable material such that upon application of an external force to said plug when said cover is in said third position, said force is transferred to said mounting surfaces thereby causing resilient deformation of said mounting surfaces and disengagement of said projections from said guideways, placing said cover out of locking engagement with said plug.
Claim 3
Dependent Claim
61 words
A connection apparatus of claim 1 wherein each of said L-shaped guideways includes a first leg and a second leg each extending from a common vertex, said guideways being positioned in said first and third positions, with said projections disposed in said first leg and said guideways being positioned in said second position with said projections disposed in said second leg.
Claim 4
Dependent Claim
14 words
A connection apparatus of claim 1 wherein said cover is formed of frangible material.
