- guide grooves 34 are 12.5 mm long and 3.0 mm wide.
- Guide ribs 50 are 2.0 mm wide so that a close fit is provided between the guide ribs and the guide grooves.
- the ribs have lengths of approximately the same lengths as the guide grooves so that the ribs bottom-out in the guide grooves as seen in FIG. 3. Therefore, with this close fit, plug 28 of plug connector 12 cannot be inserted into receptacle 16 at a sufficiently severe angle as shown in FIG. 8, because the tips of guide ribs 50 must enter guide grooves 34 and, with the close fit between the ribs and the grooves along with the lengths of the ribs and grooves, this intermitting relationship will cause plug connector 12 to “straighten-out” on insertion into receptacle 16 . As a result, the straightened plug connector will cause alignment pins 30 to be aligned with and enter guide holes 72 without engaging mating face 44 or damaging ferrules 48 and the terminated optical fibers.
- a redundant dimensional relationship exists between plug 28 and alignment pins 30 , along with receptacle 16 , to also prevent plug connector 12 from being inserted into receptacle 16 at a severe angle, i.e., without straightening the plug connector so that the alignment pins are aligned with guide holes 72 .

- Double-headed arrow 86 in FIG. 4 represents the “Y” or minor dimension of plug 28 and is 20.0 mm. Therefore, it can be seen that the dimensions (46.0 mm ⁇ 20.0 mm) of plug 28 establishes a close fit within receptacle 16 which has very slightly larger dimensions (46.5 mm ⁇ 20.75 mm).
- receptacle 16 has a depth as represented by double-headed arrow 88 in FIG. 5 in relation to the combined length of plug 28 and the projecting alignment pins 30 , as indicated by double-headed arrow 90 in FIG. 8, to prevent the alignment pins from engaging mating face 44 within the receptacle.
- the depth of receptacle 16 in a “Z” direction as represented by double-headed arrow 88 in FIG. 5, is on the order of 25.75 mm.
- the combined length of plug 28 and projecting alignment pins 30 in the “Z” direction as indicated by double-headed arrow 90 in FIG. 8, is on the order of 25.85 mm.
- the alignment pins are prevented from engaging mating face 44 at the bottom of the receptacle before the pins are aligned with guide holes 72 in mating face 44 .
- This positional relationship is a redundant dimensional relationship in addition to that of guide ribs 50 and guide grooves 34 , to ensure that the alignment pins do not ever engage mating face 44 of ferrules 48 during mating of plug connector 12 and adapter assembly 18 .
Abstract
A fiber otic connector assembly includes a receptacle for receiving a fiber optic connector along an optic axis. A housing has an open end for receiving the fiber optic connector. A pair of shutter members are pivotally mounted on the housing at opposite sides of the open end for pivotal movement toward and away from each other to close and open the open end. One of the shutter members is shorter than the other shutter member so that the one shutter member closes before the other shutter member and, thereby, prevents binding therebetween. The receptacle has a bottom mating face, and the fiber optic connector has a plurality of alignment pins insertable into guide holes in the mating face. The fiber optic connector assembly include particular dimensional relationships to prevent the alignment pins from engaging the mating face rather than entering the guide holes.
Description
- This invention generally relates to the art of fiber optic connectors and, particularly, to a fiber optic connector which includes a pair of shutter members, and a connector assembly which is particularly dimensioned to prevent alignment pins of one connector from damaging an internal mating face of a second connector.
- Fiber optic connectors of a wide variety of designs have been employed to terminate optical fiber cables and to facilitate connection of the cables to other cables or other optical fiber transmission devices. A typical optic fiber connector includes a ferrule which mounts and centers an optical fiber or fibers within the connector. The ferrule may be fabricated of such material as ceramic. A ferrule holder or other housing component of the connector embraces the ferrule and may be fabricated of such material as molded plastic. A spring may be disposed within the housing or ferrule holder such that the ferrule is yieldably biased forwardly for engaging another fiber-mounting ferrule of a mating connecting device.
- A plurality of fiber optic connectors often are mated in an adapter with another connector or connectors, with the adapter aligning the fibers to provide low insertion losses. The adapter couples the mating connectors together so that their encapsulated fibers connect end-to-end. The adapter may be an in-line component, or the adapter can be designed for mounting in an opening in a panel, backplane, circuit board or the like.
- Various problems are encountered when terminating optical fibers in fiber optic connectors versus terminating electrical conductors in electrical connectors, when situations arise wherein a fiber end of an “active” fiber optic connector is exposed. A typical situation might arise when one of the fiber optic connectors at one end of an adapter is removed, leaving the other “active” fiber optic connector or connectors in the adapter.
- In particular, an exposed fiber end may be damaged by adverse environmental hazards, and the accumulation of dust and dirt may impair the optical transmission capabilities of the fiber. Another very important problem is to protect an operator's eyes from dangerous light beams from the exposed end of an active optical fiber. For instance, an operator's eyes may be damaged from dangerous light beams exiting an unprotected receptacle or adapter.
- Heretofore, dust covers, end caps or spring-loaded shutter members have been used to close an open end of an adapter to, thereby, cover the exposed fiber ends to protect the fiber ends from adverse environmental hazards and to prevent light energy from the fiber ends from exiting the adapter. One such spring-loaded shutter member is pivotally mounted on the adapter adjacent the open end thereof and is pivotally movable to close and open the open end. The shutter member extends across the optic axis of the connector/adapter assembly when the shutter member is closed. The shutter member may be pivotable away from the optic axis to its open condition.
- In some connector assemblies, a pair of opposing shutter members are used, versus a single shutter member. The pair of shutter members are pivotally mounted at opposite sides of the connector receptacle, and the use of a pair of opposing shutter doors has a number of advantages. First, the two shutter members save considerable axial space which otherwise would be required to accommodate the full pivoting action of a single shutter member which would be approximately twice the size of a pair of shutter members. Second, it is easier to open the two smaller shutter members because smaller springs can be provided. When a mating connector has alignment pins, the pins generally are at the center of the connector and, thereby, most forces are applied near the edges of the pair of shutter members, whereas with a single shutter member a large force is required on one side of the centerline than the other side. Third, the wiping surface of either of the pair of shutter members is one-half the wiping surface of a single shutter member. With the single shutter member, dust collected on the outside of the shutter member is carried all the way into the interface area between the connectors. With a pair of shutter members, any dust which accumulates on the outer surfaces thereof will be deposited away from the mating interface rather than being carried further inwardly.
- However, the use of a pair of opposing shutter members continue to create problems in being able to completely close an open end of a receptacle without causing binding between the shutter members. The present invention is directed to solving this problem by a simple arrangement whereby one shutter member is shorter than the other shutter member and, thereby, the shorter shutter member closes before the longer shutter member and there can be no binding.
- The invention herein is directed to solving other problems in mating such fiber optic connectors by providing specific dimensional relationships between a receptacle and a plug of a connector assembly to prevent alignment pins on the plug from damaging the mating interface within the receptacle.
- An object, therefore, of the invention is to provide a new and improved fiber optic connector assembly of the character described.
- According to one aspect of the invention, a connector receptacle is provided for receiving a fiber optic connector along an optic axis. The receptacle includes a housing having an open end for receiving the fiber optic connector inserted thereinto on the optic axis. A pair of shutter members are pivotally mounted on the housing at opposite sides of the open end for pivotal movement toward and away from each other toward and away from the optic axis to close and open the open end. One of the shutter members is shorter than the other shutter member in a direction radially of the axis so that the one shutter member closes before the other shutter member and, thereby, prevents binding therebetween.
- In the exemplary embodiment of the invention, the shutter members are generally planar and rectangular for closing a generally rectangular open end of the housing. An inner edge of the longer shutter member overlaps an inner edge of the shorter shutter member when the shutter members are closed. A spring is operatively associated between each shutter member and the housing to bias the respective shutter member toward its closed positions. The springs have generally equal spring constants to apply a generally equal spring force on each shutter member.
- According to another aspect of the invention, a fiber optic connector assembly includes a first connector having a housing with a receptacle defining an optic axis. A bottom of the receptacle defines a mating face with a pair of transversely spaced pin-receiving guide holes. A second connector includes a housing forming a plug insertable into the receptacle of the first connector on the optic axis. The second connector has a pair of transversely spaced alignment pins projecting axially from the plug for insertion into the guide holes in the mating face at the bottom of the receptacle of the first connector. The plug and the receptacle have respective cross-dimensions such as to provide a sufficiently close fit, and the receptacle is of sufficient depth in relation to the length of the plug and the projecting alignment pins, to prevent the alignment pins from engaging the mating face at the bottom of the receptacle rather than entering the guide holes in the mating face.
- According to still another aspect of the invention, an elongated guide rib is provided on one of the outside of the plug of the second connector or the inside of the receptacle of the first connector, insertable into an elongated groove in the other of the outside of the plug or the inside of the receptacle when the plug is inserted into the receptacle. The rib and the groove extend generally parallel to the optic axis. The rib has a sufficiently close fit in the groove, and the rib and groove have sufficient lengths in relation to the length of the alignment pins, to prevent the alignment pins from engaging the mating face at the bottom of the receptacle rather than entering the guide holes in the mating face.
- Other objects, features and advantages of the invention will be apparent from the following detailed description taken in connection with the accompanying drawings.
- The features of this invention which are believed to be novel are set forth with particularity in the appended claims. The invention, together with its objects and the advantages thereof, may be best understood by reference to the following description taken in conjunction with the accompanying drawings, in which like reference numerals identify like elements in the figures and in which:

Each guide rib is approximately 2.0 mm wide and substantially the same length asguide grooves 34. - FIG. 5 shows a feature of the invention which comprises a pair of shutter members or
doors adapter assembly 18 withinreceptacle 16. The shutter members are pivotally movable toward and away from each other and toward and away fromoptic axis 14 to close andopen end 16 a ofreceptacle 16. FIGS. 5 and 7 show the shutter members in their closed condition. FIG. 4 shows the shutter members in their open condition, having been moved thereto byplug 28 ofplug connector 12. - FIG. 6 shows that each
shutter member pivot shaft 68 at each opposite end thereof. The pivot shaft is journalled in opposite minor side walls offront housing part 36 ofadapter assembly 18. Atorsion spring 70 is wrapped around the pivot shaft at each opposite end of each shutter member. As seen in FIG. 5, each torsion spring has oneend 70 a abutting the back side of one of the shutter members and anopposite end 70 b abutting an inside wall offront housing part 36 of the adapter assembly. The torsion springs, thereby, bias the shutter members to their closed positions shown in FIG. 5. The torsion springs are fabricated to have equal spring constants to apply generally equal forces to each opposite end of each shutter member. - The invention contemplates a unique arrangement to prevent binding of
shutter members shutter member 60 is shorter thanshutter member 62. Therefore, theshorter shutter member 60 will close before thelonger shutter member 62 because of the smaller length and smaller turning or pivoting radius. The shutter members are generally rectangular as best seen in FIG. 7, and the free edge of the longer shutter member overlaps the free edge of the shorter shutter member as seen in FIG. 5, when the shutter members are closed. - FIG. 8 represents a situation when an operator may attempt to insert
plug 28 ofplug connector 12 intoreceptacle 16 ofadapter assembly 18 at an angle or skewed orientation which could cause problems if alignment pins 30 could engagemating face 44 at the bottom ofreceptacle 16 before the alignment pins are aligned with a pair of pin-receiving guide holes 72 in the mating face ofrear housing part 38 of the adapter assembly. Distal ends 32 a ofjack screws 32 are threaded into internally threadedholes 74, but the projecting ends of the jack screws are shorter than the projecting ends of the alignment pins, so the jack screws would not create any problems. If alignment pins 30 were able to engage mating facing 44 before the pins are aligned with guide holes 72, the alignment pins could damageferrules 48 ofterminal modules 40, along with the ends of the optical fibers which are terminated by the ferrules. The alignment pins also could damage any one of a plurality of smaller guide pins 76 which project from the ferrules. - In order to ensure that alignment pins30 are aligned with guide holes 72 (FIG. 8), a redundant dimensional system is provided between
plug connector 12 andadapter assembly 18, particularlyfront housing part 36 of the adapter assembly which definesreceptacle 16. First of all, guideribs 50 withinreceptacle 16 and guidegrooves 34 onplug connector 12 have a sufficiently close fit and are of sufficient lengths to preventalignment pins 30 from engagingmating face 44 at the bottom ofreceptacle 16 before the alignment pins are aligned with guide holes 72. Specifically, as stated above, guidegrooves 34 are 12.5 mm long and 3.0 mm wide.Guide ribs 50 are 2.0 mm wide so that a close fit is provided between the guide ribs and the guide grooves. The ribs have lengths of approximately the same lengths as the guide grooves so that the ribs bottom-out in the guide grooves as seen in FIG. 3. Therefore, with this close fit, plug 28 ofplug connector 12 cannot be inserted intoreceptacle 16 at a sufficiently severe angle as shown in FIG. 8, because the tips ofguide ribs 50 must enterguide grooves 34 and, with the close fit between the ribs and the grooves along with the lengths of the ribs and grooves, this intermitting relationship will causeplug connector 12 to “straighten-out” on insertion intoreceptacle 16. As a result, the straightened plug connector will cause alignment pins 30 to be aligned with and enterguide holes 72 without engagingmating face 44 ordamaging ferrules 48 and the terminated optical fibers. - A redundant dimensional relationship exists between
plug 28 and alignment pins 30, along withreceptacle 16, to also preventplug connector 12 from being inserted intoreceptacle 16 at a severe angle, i.e., without straightening the plug connector so that the alignment pins are aligned with guide holes 72. Specifically, double-headedarrow 80 in FIG. 3 represents the major or “X” dimension ofreceptacle 16 and double-headedarrow 82 in FIG. 4 represents the minor or “Y” dimension ofreceptacle 16. In the illustrated embodiment, the major or “X”dimension 80 is 46.6 mm, whereas the “Y” orminor dimension 82 is 20.75 mm. Still referring to FIGS. 3 and 4, double-headedarrow 84 represents the “X” or major dimension ofplug 28 and is 46.0 mm. Double-headedarrow 86 in FIG. 4 represents the “Y” or minor dimension ofplug 28 and is 20.0 mm. Therefore, it can be seen that the dimensions (46.0 mm×20.0 mm) ofplug 28 establishes a close fit withinreceptacle 16 which has very slightly larger dimensions (46.5 mm×20.75 mm). - In addition,
receptacle 16 has a depth as represented by double-headedarrow 88 in FIG. 5 in relation to the combined length ofplug 28 and the projecting alignment pins 30, as indicated by double-headedarrow 90 in FIG. 8, to prevent the alignment pins from engagingmating face 44 within the receptacle. Specifically, the depth ofreceptacle 16 in a “Z” direction as represented by double-headedarrow 88 in FIG. 5, is on the order of 25.75 mm. The combined length ofplug 28 and projecting alignment pins 30 in the “Z” direction as indicated by double-headedarrow 90 in FIG. 8, is on the order of 25.85 mm. Therefore, with the sufficiently close fit betweenplug 28 andreceptacle 16 as described above, along withreceptacle 16 being of a sufficient depth in relation to the length ofplug 28 and the projecting alignment pins 30, the alignment pins are prevented from engagingmating face 44 at the bottom of the receptacle before the pins are aligned with guide holes 72 inmating face 44. This positional relationship is a redundant dimensional relationship in addition to that ofguide ribs 50 and guidegrooves 34, to ensure that the alignment pins do not ever engagemating face 44 offerrules 48 during mating ofplug connector 12 andadapter assembly 18. - It will be understood that the invention may be embodied in other specific forms without departing from the spirit or central characteristics thereof. The present examples and embodiments, therefore, are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein.
