Universal cable socket apparatus particularly adapted for use with fiber optic cables

An adjustable connector apparatus for accomodating various diameter fiber optic cable assemblies to be exposed to a source of light contained within a housing upon which said connector apparatus is mounted comprising:

• (a) a first housing section having an aperture and having on a top surface a plurality of transverse slots each communicating with said aperture and each extending transverse thereto, said housing having a threaded outer peripheral portion,
• (b) a plurality of clamp members, each having a sloping back wall and having an internal hollow contiguous with an open bottom end, each separate one positioned within an associated one of said slots with said back wall facing the outer periphery of said first housing section with a spring in each hollow,
• (c) means located in each slot and adapted to coact with each spring in said slot to compress the same when the associated clamp member is moved towards said aperture,
• (d) a second housing section having an aperture coaxial with said aperture in said first housing and having a downwardly depending circular sloping flange positioned about said aperture, with the inner periphery of said housing threaded so that when emplaced upon said first housing said second housing can rotatably move towards or away from said slots, with said flange coacting with the back wall of each clamp member to push said members into said aperture for one direction of rotation and to allow said clamp members as biased by said springs to move out of said aperture for the oppposite direction of rotation.
