Abstract
Abstract A fiber optic drawer connector assembly comprises an insert having an inner cavity for the insertion of an optical lens assembly and an associated ferrule fiber holder. The insert is at least partially surrounded by a shroud and the shroud in turn positioned in the interior of a housing so that a flange at the end of the shroud comes into abutment with a stopping member at one end of the housing. The housing, as well as subassemblies enclosed thereby, is designed to be inserted into and through an aperture in a wall until an intermediate flange extending from the exterior surface of the housing comes into contact with a surface on one side of the wall. A cap is threaded over an open end of the housing and into abutment with an insert flange. Springs are provided so that the insert is maintained in secure relationship to the housing and shroud and so that the lens and ferrule are secure within the insert.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
346 words
A fiber optic drawer connector assembly, the assembly comprising: a unitary, generally cylindrical insert having a radially outwardly extending flange portion at one end and a radially inwardly extending flange portion at the other end, said insert providing an inner cavity for accommodating a lens assembly and an associated ferrule, a unitary, generally cylindrical shroud surrounding at least a portion of the insert and having a flange portion at one end, a housing surrounding at least a portion of the shroud and a portion of the insert and having a cylindrical contour with an interior surface and a threaded exterior surface, a flangelike member extending radially outwardly at an intermediate point on the exterior surface of the housing, and a radially inwardly extending stopping portion at one end for abutment with the flange portion of the shroud, and a cap characterized by an angular U-shaped cross-section and having a threaded inner surface for engagement with the threaded surface of the housing, a first spring inserted into the cavity of the insert, and a second spring surrounding the insert and disposed between the insert radially outwardly extending flange portion and the flange portion of the shroud, and retaining means surrounding the outer surface of the housing for maintaining the housing in a substantially fixed relationship with a planar surface through which the housing is inserted, whereby a lens assembly and associated ferrule may be inserted into the shroud, the shroud into the housing so that the flange portion of the shroud tends to abut the stopping portion of the housing, the housing inserted through a complementary opening in a plane so that the housing flangelike member tends to abut a first surface of the plane, the retaining means positioned around the housing into contact with a second surface of the plane and the cap mated to the housing so that a central segment of the cap comes into contact with the radially outwardly extending flange portion of the insert whereby the first spring maintains the lens and associated ferrule in a secure position within the insert cavity.
