This is the non-provisional application of U.S. Application Ser. No. 62/884,520, filed Aug. 8, 2019, entitled PUSH PULL MECHANISM FOR OUTDOOR RATED HYBRID CONNECTOR, the entire contents of which is incorporated herein by reference.
The present disclosure relates generally to fiber optic connectors and connector assemblies, and specifically to an outdoor rated connector assembly ingress protected from moisture and debris.
The reliability of communication infrastructure depends on secure connections between components, such as cable segments, network equipment, and communication devices. Such connections are continually exposed to dust, dirt, moisture, and/or other contaminants that may infiltrate the connections and degrade performance or even sever the connection between components. Conventional connection assemblies, such as typical fiber optic connectors, are generally not capable of providing an adequate seal to fully prevent the ingress of unwanted fluids (for instance, water) or solid contaminants. Fiber optic network segments are particularly vulnerable because fiber optic connections require extremely precise termination and alignment between connected components and cable segments that maybe damaged by the presence of fluid or solid contaminants. As such, fiber optic network segments connected using conventional technology are very susceptible to performance and/or availability degradation over time. Accordingly, telecommunication network providers would benefit from a connection assembly capable of maintaining a sealable and secure connection configured to prevent the ingress of unwanted materials into a connector assembly with a reduced number of parts and ease of separating the connector assembly to access internal components.
Corresponding reference numbers indicate corresponding parts throughout the figures.
An outdoor rated connector deploying a lockable collar nut prevents disconnecting a connector and mating connector is disclosed in U.S. Pat. No. 9,477,049 B2, Gniadek et al., Lockable Connectors and Connection Assemblies, granted Oct. 25, 2016, and assigned to the owner of the present invention, and included by reference in its entirety. Gniadek does not disclose a displaceable collar nut in a longitudinal direction to unlock the connector and the mating connector, which is an improvement of the present invention.
The present invention discloses an outdoor rated connector assembly, with environmental seals, formed by a first connector and a mating connector releasably secured or locked by a ring or lock ring. A user can unlock or unmate the first connector and mating connector by pulling an outer collar nut in a rearward direction, to gain access to the internal components to service the connector assembly.
The connector assembly has opposing fiber optic connectors that are not rated for operating outside without additional protection, and a key indicator is provided to align a wing with a slot in the mating connector to ensure the opposing connectors are in the correct polarity to ensure optical and/or electrical transmission.
The present invention solves the problem of limited physical access to the separate the connector assembly into a first connector and a mating connector to access internal components for servicing. Due to the limited space between connector assemblies, a user may not be able to rotate the collar nut to unlock the connector assembly, as disclosed in Gniadek. This and other improvements over the prior art are disclosed and claimed in the present invention.
The foregoing, as well as additional objects, features and advantages of the present disclosure is apparent from the following detailed description, which proceeds with reference to the accompanying drawings Detailed Description:
This disclosure is not limited to the particular systems, devices and methods described, as these may vary. The terminology used in the description describes particular versions or embodiments only, and does not limit the scope of the present invention.
As used in this document, the singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art. Nothing in this disclosure is an admission that the embodiments described in this disclosure are not entitled to antedate such disclosure by virtue of prior invention. As used in this document, the term “comprising” means “including, but not limited to.”
As used herein, the term “optical fiber” is intended to apply to all types of single mode and multi-mode light waveguides, including one or more bare optical fibers, coated optical fibers, loose-tube optical fibers, tight-buffered optical fibers, ribbonized optical fibers, bend performance optical fibers, bend insensitive optical fibers, nanostructured optical fibers or any other expedient for transmitting light signals. The term optical fiber cable may further include multi-fiber optic cables having a plurality of the optical fibers.
A “fiber optic cable” or an “optical cable” refers to a cable containing one or more optical fibers for conducting optical signals in beams of light. The optical fibers can be constructed from any suitable transparent material, including glass, fiberglass, and plastic. The cable can include a jacket or sheathing material surrounding the optical fibers. In addition, the cable maybe connected to a connector on one end or on both ends of the cable.
For connection of cables together or with other fiber optic devices, the terminal ends of a cable may include a connector. A “connector,” as used herein, refers to a device and/or components thereof that connects a first optical fiber cable to a second optical fiber cable. The connector maybe configured for fiber optic transmission or electrical signal transmission, or both. The connector may be any suitable type now known or later developed, such as, for example, a ferrule connector (FC), a fiber distributed data interface (FDDI) connector, an LC connector, a mechanical transfer (MT) connector, a square connector (SC) connector, an SC duplex connector, a straight tip (ST) connector, or a behind-the-wall (BTW) connector. The connector assembly maybe defined by a connector housing body with a fiber optic connector therein. In some embodiments, the housing body may incorporate any or all of the connector assembly components described the present application.
Without departing from the scope of the invention, and included by reference in its entirety, U.S. Pat. No. 9,755,382 B2, Gniadek, titled “Connector System with Interchangeable Connector Module for Optical Fibers, Electrical Conductors, or Both”, granted Sep. 5, 2017, discloses an electrical transmission line can be combined with a fiber optic transmission line.
Referring to
As depicted in
In the above detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not limiting. Other embodiments may be used, and other changes maybe made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein.
The present disclosure is not to be limited in terms of the particular embodiments described in this application, which are illustrations of various aspects. The present disclosure is to be limited only by the terms of the appended claims, along with the full scope of equivalents to which such claims are entitled. It is to be understood that this disclosure is not limited to particular methods, reagents, compounds, compositions or biological systems, which can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (for example, bodies of the appended claims) are generally intended as “open” terms (for example, the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” et cetera). For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (for example, “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations.
