Abstract
Description
- This invention relates to a cleaning apparatus for fiber optic connectors.
- Optical fibers are quickly replacing wires for the transmission of data in the electronics industry. Not only are the fibers small, but light data transmission rates are very high in comparison to those of wire connections. Fiber optic cables may contain one or more of these optical fibers. Connectors are used to mate several optical fibers or cables as well as connect such cables to backplanes and system cards of computer and telecommunication systems.
- Such optical fiber connectors are shown in PCT publication WO/98/00741 and in FIG. 1 on the present application. Within this
connector 100, a ferrule 112 precisely positions a plurality of optical fibers 108 for mating with fibers in a similar ferrule of a mating connector. The ferrule end faces are finely polished to minimize distance between the fibers on each ferrule 112. A spring in eachmating connector 100 biases the ferrules 112 together. Optionally, one of the twomating connectors 100 may contain alignment pins 106 on opposite sides the ferrule 112. - A problem exists with these connectors in that dust and debris deposited between mating ferrules can contaminate the connectors and reduce or prohibit the transmission of light therebetween. Accordingly, there is a need to clean optical fiber connectors, but cleaning the connectors may be difficult especially when a cable needs to be removed from the system to perform the cleaning procedure.
- For example, in large telecommunication systems an entire backplane supports attachment of numerous optical fiber cables. System cards are slid on rails and then plugged into the backplane assembly. Many of these cards contain one or more system card optical connector housings to connect the optical fiber cables mounted on the backplane to the system card. Not only are many of these cables in the backplane difficult to access, but removal of a cable is time consuming and therefore may prove financially prohibitive.
- Therefore, there is a need for a cleaning tool that can remove dust and debris from a fiber optic cable connector particularly where removal of the cable is difficult. Further, there is a need to clean multiple optical fiber optic connectors mounted on a backplane simultaneously. There is also a need to clean similar fiber optic connectors on system cards.
- It is therefore an object of this invention to provide a cleaning tool for removing debris and dust from a connector.
- It is further object of the invention to remove small pieces of debris and dust from an optical connector using a cleaning assembly which is a matable to a contaminated optical connector.
- Another object of the invention is to provide a cleaning kit to clean optical fiber cables attached to a system backplane.
- These and other objects have been achieved by providing a cleaning insert for use in a cleaning assembly. The cleaning insert has a main body with a cleaning pad secured on one end and a latching mechanism on the opposite end. A cleaning agent is applied to the cleaning pad and the cleaning insert is secured in a housing to form a cleaning assembly. The cleaning assembly is matable with an optical connector to be cleaned.
- Other objects and advantages of the cleaning assembly and method will become apparent to those skilled in the art upon reading the detailed description.
- The invention will now be described by way of example with reference to the accompanying drawings of which:
- FIG. 1 is a three-dimensional view of a prior art optical connector.
- FIG. 2 is a three-dimensional view of the cleaning assembly and cleaning insert of the present invention.
- FIG. 3 is a cross-sectional view taken along the line3-3 of FIG. 2 showing the cleaning apparatus of the present invention.
- FIG. 4 is a three-dimensional view of an alternative embodiment of the cleaning insert.
- FIG. 5 is a three-dimensional view of a daughter card cleaning kit.
- FIG. 6 is a three-dimensional view of an alternate daughter card cleaning kit.
- An embodiment of the present invention will be described with reference to the drawing figures where like numerals represent like elements throughout. Although the embodiment illustrates cleaning a particular type of optical fiber connector, the present invention is applicable to other connectors by minor modifications.
- The invention will first be described generally with reference to FIG. 2. A
cleaning assembly 10 being matable with and having features similar to theconnector 100 of FIG. 1 contains aninsert holder 20 in place of the ferrule 112. Theinsert holder 20 is biased toward themating end 12. An opening 22 is formed in theinsert holder 20. A cleaning insert 30 fits within the opening 22. - Each of the major components will now be described in greater detail with reference to FIGS. 2 and 3. Beginning with the
cleaning assembly 10 and referring first to FIG. 3, the major components include anouter housing 40, andinner housing 50, aninsert holder 20, a spring 60, and arear plug 70. Referring to FIG. 2, theouter housing 40 features agrip portion 42 extending from arear end 44 toward themating end 12. A plurality ofcams 46 are positioned around awindow 48. Theinner housing 50 is slidingly positioned within theouter housing 40 and projects from thewindow 48 and themating end 12. Theinner housing 50 features a first latchingshoulder 52 positioned near themating end 12 and a second latching shoulder 54 positioned within thewindow 48. A latch 56 also extends from theinner housing 50 at themating end 12. Returning to FIG. 3, aninsert stop 58 extends inward near themating end 12 and a pair of openings 59 are disposed near therear end 44. - The
insert holder 20 has an opening 22 which extends rearward from themating end 12. As best shown in FIG. 3, a pair ofprojections 24 extend inward fromside walls 26 and are positioned within the opening 22. Eachprojection 24 has arear shoulder 28. A wide portion 29 is disposed at the rear end 27 of theinsert holder 20. A spring 60 is positioned against the rear end 27 of theinsert holder 20. It should be understood by those reasonably skilled in the art that while a coil spring is shown here, other shaped springs or biasing devices which are well-known in the art could be substituted. Therear plug 70 features a narrow portion 72 and awide portion 74. Anopening 76 extends through both the narrow andwide portions 72,74. A pair oflatching projections 78 extend outward from the narrow portion 72. Ashoulder 79 is positioned on an outer surface at the transition between the wide andnarrow portions 74,72. - The
cleaning insert 30 will now be described in greater detail with reference to FIGS. 2 and 3. Projecting rearward from a main body 31 are a pair ofresilient legs 32. Eachresilient leg 32 has aprojection 34 extending outward near afree end 37. Ataper 38 extends from thefree end 37 to theprojection 34. Thecleaning pad 36 is positioned on the main body 31 opposite theresilient legs 32. Thecleaning pad 36 is formed of a resilient/compliant material to conform to the mating surface of a ferrule 112 to be cleaned. The material selected should not apply undue pressure on that mating surface. A suitable material for thecleaning pad 36 is acrylic foam. Depending upon thecleaning agent 37 used, another suitable material for thecleaning pad 36 is a low residue felt. A cleaningagent 37 is applied to thecleaning pad 36 opposite the main body 31 and aprotective cover 39 is positioned over the cleaningagent 37. Thecleaning agent 37 is preferably a slightly tacky adhesive material such as White PET 550 Adhesive. The material selected should have the ability to lift debris from the surface to be cleaned yet not leave any residue. Alternate materials such as isopropyl alcohol with afelt cleaning pad 36 could be utilized as a cleaning agent as long as the material is capable of capturing debris without leaving a residue. - Assembly of the major components will now be described in greater detail again with reference to FIG. 3. First, the
inner housing 50 is inserted into theouter housing 40. Next, theinsert holder 20 is inserted into theinner housing 50 until the wide portion 29 engages theinsert stop 58. The spring 60 is inserted against the rear end 27 of theinsert holder 20. Therear plug 70 is inserted such that the latchingprojections 78 reside within openings 59 and theshoulder 79 is positioned adjacent to rear end of theinner housing 50. - The
cleaning insert 30 is preferably molded such that the main body 31 andresilient legs 32 are integral. Next, thecleaning pad 36 is fixed to the main body 31 preferably utilizing an adhesive. Thecleaning pad 36 could be applied utilizing other methods known to those skilled in the art such as a tongue and grove joint. Next, the cleaningagent 37 is applied to the end of thecleaning pad 36. Thecleaning agent 37 is preferably another adhesive which is less tacky than the adhesive utilized to fix thecleaning pad 36 to the main body 31. Alternate cleaning agents include fluids such as alcohol or distilled water. Those skilled in the art will appreciate that thecleaning agent 37 should be selected to be compatible with the material selected for the cleaning pad 36.The completedcleaning insert 30 is then inserted into theopening 22 of theinsert holder 20 from themating end 12. Thetapers 38 first engage theprojections 24 of theinsert holder 20 to urge theresilient legs 32 of thecleaning insert 30 toward each other during insertion. The cleaninginsert 30 is further urged intoopening 22 untilprojections 34 pass overprojections 24 and lock behindrear shoulders 28. - An
alternate cleaning insert 130 is shown in FIG. 4. Thiscleaning insert 130 is similar to the embodiment of FIG. 2 except thatpin receiving passageways 132 extend through themain body 131 andslits 134 are formed in thecleaning pad 136. Theslits 134 are aligned with thepin receiving passageways 132. Each of thepin receiving passageways 132 is preferably tapered to be largeradjacent cleaning pad 136 and smaller adjacent the resilient legs. - In use, either a
cleaning insert 30 or analternate cleaning insert 130 is inserted into theinsert holder 20 of a cleaningassembly 10. Theprotective cover 39 is then removed from thecleaning pad 36. Next, the cleaningassembly 10 is mated with anoptical connector 100 such as the one shown in FIG. 1. In this particular case, analternate cleaning insert 130 should be utilized to receive alignment pins 106. It should be understood however that thealternate cleaning insert 130 could be utilized to clean either a connector with alignment pins 106 or a connector without alignment pins 130. Thecleaning pad 36 contacts the end face of the ferrule 112. Upon unmating, any debris present on the ferrule 112 will stick to thecleaning pad 36 and removed with the cleaningassembly 10. It should be understood by those reasonably skilled in the art that while thecleaning insert 30 and cleaningassembly 10 are shown as being generally rectangular, this concept is equally adaptable to other optical connectors. For example, a cleaning insert utilizing the concepts of this invention could be adapted for use in other commercially available optical connectors such as those having round or other shaped cross sections. - The cleaning
assembly 10 is adaptable for use in cleaning optical connectors mounted within a backplane assembly. Daughter cards are typically insertable into a backplane assembly along guide rails. Each daughter card may be configured to mate with several optical connectors mounted within the backplane assembly. One example of the daughtercard cleaning kit 600 is shown in FIG. 5. Here, acoupling housing 604 is mounted along an edge of adaughter card 602. The cleaningassembly 10 is secured within thecoupling housing 604. The cleaninginsert 30 is inserted into the mating end of the cleaningassembly 10 as described above. A plurality of spare cleaning inserts 606 are mounted to thedaughter card 602. The cleaninginsert 30 may be removed and replaced by one of the spare cleaning inserts 606. - Another example of the daughter
card cleaning kit 700 is shown in FIG. 6.
