Optical fiber connector

Abstract

Various exemplary embodiments of an optical fiber connector having a one-piece housing are shown and described. The housing includes a tailpiece which extends rearward from a housing body. The tailpiece provides a location for securing strength members which may be associated with an optical fiber or optical fiber cable attached to the optical fiber connector. The tailpiece is integral formed with the housing. Thus, stress applied to the optical fiber at an angle to the longitudinal axis of the connector will not result in a degradation of the connector mechanical or optical performance. The optical fiber connector components are advantageously inserted in the connector housing through the forward end of the housing and retained with a retainer.

Description

FIELD OF THE INVENTION [0001] The invention relates generally to an optical fiber connector, and more particularly to an optical fiber connector having a one-piece housing. TECHNICAL BACKGROUND [0002] Optical fibers are widely used in a variety of applications, including the telecommunications industry in which optical fibers are employed in a number of telephony and data transmission applications. Due, at least in part, to the extremely wide bandwidth and the low noise operation provided by optical fibers, the use of optical fibers and the variety of applications in which optical fibers are used are continuing to increase. For example, optical fibers no longer serve as merely a medium for long distance signal transmission, but are being increasingly routed directly to the home or, in some instances, directly to a desk or other work location. [0003] With the ever increasing and varied use of optical fibers, it is apparent that efficient methods of coupling optical fibers, such as to...

Benefits of technology

[0007] According to the present embodiment, a subassembly comprising a ferrule holder, a ferrule and a lead-in tube, the ferrule and the lead-in tube are disposed within the ferrule holder and the subassembly is inserted into the housing passage through the housing first end. A spring element is disposed between a shoulder within the housing passage and a flange on the ferrule holder and a retainer is inserted into the housing passage through the housing first end for retaining the subassembly within the housing. Preferably, the optical fiber connector housing further comprises a latching arm for latching the optical fiber connector to an optical fiber connector adapter or other piece of optical fiber hardware. The insertion of such components as the subassembly, spring element and retainer into the housing passage through the forward, first end of the housing advantageously permits the optical fiber connector of the present invention to exhibit a very small form.

[0008] The optical fiber connector according to the present embodiment preferably further comprising a trigger member. The trigger member, for example, may minimize snagging of the connector latching arm when the connectorized optical fiber is pulled in a backward direction, and is intended to ease operation of the latching arm. The trigger member latching arms preferably engage with recesses on the housing body. A clamping element may be used to secure strength members which may be associated with an optical fiber to which the optical fiber connector may be attached.

[0011] According to the present embodiment of the invention, the ferrule holder may include a flange. The flange preferably also has a keyway for slidably engaging with a key within the retainer for providing correct orientation of the ferrule holder within the retainer. Alternatively, the key and keyway may be reversed, with the key located on the ferrule holder and the keyway disposed within the retainer. Preferably, the ferrule holder includes a generally conical portion. The conical portion may be used to provide self-centering capability for the ferrule holder within the retainer.

Problems solved by technology

If the stress angle is large enough, the high stress level at the attachment member / housing joint may cause the joint to fail and the attachment member to separate from the rest of the connector assembly.

The failure of the attachment member may degrade the transmission performance of the optical fiber, or in the worst case, cause the optical fiber to fail altogether.
