Abstract

Abstract A fiber optic connector assembly wherein two individual fiber optic connectors are retained in a side-by-side arrangement which enables relative freedom of movement therebetween so as to facilitate positioning of the retained two (also called a duplex) within a common housing. Such movement accommodates for manufacturing tolerances within the housing and/or connectors, while still assuring successful insertion within the common housing. An adapter, having two clamping portions (one for each connector) interconnected by a resilient portion, assures this movement.

Claims Analysis

Total Claims: 25
Claim 1
Independent Claim 128 words
An adapter for holding two individual fiber optic connectors of the push-pull variety in a predetermined manner of alignment prior to positioning said connectors within a corresponding connector housing, said adapter comprising: first and second clamp members, each of said clamp members adapted for clamping onto a respective one of said fiber optic connectors to hold said fiber optic connectors in a substantially side-by-side relationship; and resilient means interconnecting said first and second clamp members and oriented substantially therebetween for enabling said clamp members to move in at least four different orientations relative to each other while holding said connectors in said substantially side-by-side relationship to enable movable alignment between said clamp members prior to said positioning of said connectors within said connector housing, thereby facilitating said positioning.
Claim 2
Dependent Claim 128 words
An adapter for holding two individual fiber optic connectors of the push-pull variety in a predetermined manner of alignment prior to positioning said connectors within a corresponding connector housing, said adapter comprising: first and second clamp members, each of said clamp members adapted for clamping onto a respective one of said fiber optic connectors to hold said fiber optic connectors in a substantially side-by-side relationship; and resilient means interconnecting said first and second clamp members and oriented substantially therebetween for enabling said clamp members to move in at least four different orientations relative to each other while holding said connectors in said substantially side-by-side relationship to enable movable alignment between said clamp members prior to said positioning of said connectors within said connector housing, thereby facilitating said positioning.
