ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a kit for converting optical fiber retaining clip for use in connection with fiber optic conversion kits. The kit for converting optical fiber retaining clip has particular utility in connection with conversion kit for converting fiber optic retainer from biconic to subscription channel connector.
2. Description of the Prior Art
Kit for converting optical fiber retaining clips are desirable for converting older biconic connectors to modern subscription channel (SC) connectors a single connector at a time. This invention allows limited service interruption and the ability to use older biconic six pack connectors with newer SC connectors.
The use of fiber optic conversion kits is known in the prior art. For example, U.S. Pat. No. 4,715,251 to Margolin, et al discloses a fiber optic cable preparation tool of preparing fiber optic cable for termination with a fiber optic connector for cables of the type having a concentric arrangement, from the exterior of the center thereof, an outer protective cover, a layer of strength members and a buffer layered cover fiber. A longitudinally extending first member of the tool includes a longitudinal passage extending therethrough and the cable is mountable therein with a predetermined length extending from the front thereof. The front of the member is a frusto-conical shape on the exterior thereof and the cable is clamped within the member. A second clamp member also having a longitudinal passage therethrough is of a size such that the second clamp member can be received on the exterior of the frusto-conical end of the first member such as to hold strength members of the fiber optic cable securely against the outer surface of the frusto-conical end when the strength members are folded thereover. A sleeve press member then serves to force an inner sleeve which is mounted over the buffer covered end of the fiber into the region between the strength members and the buffered sleeve. The sleeve press member is of a predetermined length such that when engaged against the front end of the two previously described members, defines the length of fiber of the cable to be left with the buffer layer thereon so that the remaining fiber extending therefrom can have the buffer layer stripped. The disclosure also relates to a method of using the tool to prepare a fiber optic cable. However, the Margolin, et al. '251 patent does not have the ability to punch a square hole in an existing circular hole for receiving an SC connector, does not have an elongate shaft and spring loaded cutter clement, and does not have an upstanding flange for receiving and positioning cable whereby a cutting element having pivotal rotating cutters is provided.
Similarly, U.S. Pat. No. 5,321,917 to Franklin, et al discloses a tool for finishing terminated fiber optic cable that is a fixture for positioning and holding fiber optic cables for polishing. The fixture includes a cable clamping mechanism consisting of a pair of links that are pivotally attached to movable portions of a nest that receives and holds the terminated end of the cable. A holding member is positioned above the nests to steady and hold the cables in rough position while the nest accurately positions the fiber optic end for polishing. A dovetail member is provided to accurately attach the fixture to the polishing machine. The fixture is arranged to not contact the abrasive material during polishing. However, the Franklin, et al. '917 patent does not have the ability to punch a square hole in an existing circular hole for receiving an SC connector, does not have an elongate shaft and spring loaded cutter element, and does not have an upstanding flange for receiving and positioning cable whereby a cutting element having pivotal rotating cutters is provided.
Lastly, U.S. Pat. No. 5,793,921 to Wilkins, et al discloses a kit for converting a conductive cable closure to a fiber optic cable closure that has two end plate assemblies, and a closure base and a closure cover attached to the end plate assemblies. An adapter is secured within a cable entrance port in the end plate assembly to alter the end plate opening to accommodate a fiber optic cable. The adapter restrains the cable sheath against axial forces and provides a seal between the optical fiber cable, the adapter and the end plate assembly. A bracket assembly is provided to anchor the optical fiber cable strength member to the end plate assembly. The closure provides a mounting bar secured to said end plate assemblies proximate the closure base and a mounting platform secured to the mounting bar. However, the Wilkins, et al. '921 patent does not have the ability to punch a square hole in an existing circular hole for receiving an SC connector, does not have an elongate shaft and spring loaded cutter element, and does not have an upstanding flange for receiving and positioning cable whereby a cutting element having pivotal rotating cutters is provided.
While the above-described devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a kit for converting optical fiber retaining clip that allows conversion kit for converting fiber optic retainer from biconic to subscription channel connector. The Margolin, et al. '251, Franklin, et al. '917 and Wilkins, et al. '921 patents make no provision for the ability to punch a square hole in an existing circular hole for receiving an SC connector, does not have an elongate shaft and spring loaded cutter element, and does not have an upstanding flange for receiving and positioning cable whereby a cutting element having pivotal rotating cutters is provided.
Therefore, a need exists for a new and improved kit for converting optical fiber retaining clip which can be used for conversion kit for converting fiber optic retainer from biconic to subscription channel connector. In this regard, the present invention substantially fulfills this need. In this respect, the kit for converting optical fiber retaining clip according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of conversion kit for converting fiber optic retainer from biconic to subscription channel connector.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of fiber optic conversion kits now present in the prior art, the present invention provides an improved kit for converting optical fiber retaining clip, and overcomes the above-mentioned disadvantages and drawbacks of the prior art. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved kit for converting optical fiber retaining clip which has all the advantages of the prior art mentioned heretofore and many novel features that result in a kit for converting optical fiber retaining clip which is not anticipated, rendered obvious, suggested, or even implied by the prior art, either alone or in any combination thereof.
To attain this, the present invention essentially comprises a tab shaver portion that has two parallel shaver blades connected to a tab shaver handle that is slidably connected to a tab shaver retainer platform. The parallel shaver blades are for shaving off a retaining clip tab and a retaining clip threaded shoulder. A square hole punch portion has a rectangular blade connected to a square hole punch handle. The square hole punch handle is slidably connected to a square hole punch press platform. The rectangular blade is for punching out a square hole section from the retaining clip. A notch cutter portion has a plurality of rotatable cutters pivotally connected to a notch cutter platform. A notch cutter handle is slidably connected to a notch cutter platform. The rotatable cutters are for cutting a plurality of retaining notches into the retaining clip.
