Abstract
Description
- The present invention relates generally to telecommunications cable connections. More specifically, the present invention relates to adapters more connecting fiber optic telecommunications cables and removable mounts for such adapters.
- In telecommunications installations and expansions of services, it is becoming more and more common to include optical fiber cables in the transmission infrastructure. These optical fiber cables may be connected to each other using a fiber optic adapter. To connect cables with an adapter, the cables need to be terminated with a connector configured to be received within opposite ends of the adapter. A variety of adapter and connector formats are available for use in connecting such cables.
- Existing adapters are often mounted within openings in bulkheads and held in place by spring loaded clips extending from the sides of the adapter and opposed by flanges. These clips do hold the adapters securely within the opening in the bulkhead but may be difficult or inconvenient to release if the adapter needs to be removed or replaced. It is sometimes desirable to access both ends of the adapter, for instance, to clean the ends of the optical path through the adapter or a connector inserted in the rear of the adapter. Access to both sides of the bulkhead or mounting location may be restricted, so that existing adapter mounting devices do not permit access to a rear connector. Alternatively, these adapters may be held in place by screws or other fasteners extending through the flanges. The screws do securely hold the adapter to the opening but require a tool to remove.
- Improvement of existing adapters is desirable.
- The present invention relates generally to a clip arm for holding a fiber optic adapter at a mounting location. The clip arm includes a ramped outer surface which engages sides of the mounting location and cooperate with flanges of the adapter to releasably hold the adapter at the mounting location. Pulling on a first end of the adapter causes the side of the mounting location to engage the ramped outer surface of the clip arms and deflect the clip arms inward. The deflection of the clip arms is sufficient to permit an outermost point of each clip arm to pass between the sides of the mounting location and allow the adapter to be removed from the mounting location. The present invention also relates to a fiber optic adapter assembly including a clip arm with a ramped outer surface for releasably engaging and holding the adapter at a mounting location. The present invention further relates to a method of removing a fiber optic adapter from a mounting location.

- Referring now to FIGS. 1 to 3, a prior
art adapter assembly 10 includes ahousing 12 with afirst end 14 and an oppositesecond end 16. Each of theends assembly 10 may align and orient two such connectors, one positioned in each end, so that optical signals may be transmitted between the two cables. Often such adapter assemblies are mounted to an opening in a bulkhead, telecommunications panel or other device as part of a telecommunications circuit. - To secure
assembly 10 to the opening in the device, aretainer clip 18 is mounted tohousing 12 and includes a pair ofclip arms 20 extending away from a pair ofsides 22 ofhousing 12. Eachclip arm 20 includes adistal end 26 and eachside 22 includes an outwardly extendingflange 24. Eachdistal end 26 cooperates with anopposing face 30 of one of the flanges to aid in securingassembly 10 to the opening in the device. As can be seen inFIG. 3 ,distal ends 26 are spaced apart from opposingfaces 30 to receive aside 32 of an opening inbulkhead 34. To releaseassembly 10 frombulkhead 34, access to both faces ofbulkhead 34 are preferable, asspring arms 20 must be depressed adjacent one face whileassembly 10 is withdrawn from the other face. Since both sides ofbulkhead 34 may not be easily accessible, it is desirable thathousing 12 be provided with a releasable device for mounting tobulkhead 34 which may be released and removed from only one side ofbulkhead 34. It is desirable that a new adapter assembly be provided which allows for removal from a mounting location with access from only one side of the mounting location and without the need for tools or the direct actuation of any portion of the retaining clip by a user. - Referring now to FIGS. 4 to 7, an
adapter assembly 100 in accordance with the present invention includes ahousing 112 and aretainer clip 118.Housing 112 includes afirst end 114 and asecond end 116, each withopenings 128 for receiving fiber optic connectors.Retainer clip 118 includesclip arms 120 extending alongsides 122 ofhousing 112.Sides 122 each include aflange 124 with aface 130 that cooperates withclip arm 120 to holdassembly 100 to a mounting location. Whilehousings 12 ofassembly assembly 100 are similar in construction and purpose,retainer clip 118 withclip arms 120permits assembly 100 to be mounted and removed without requiring access to both faces of a mounting location.Clip arms 120 are positioned betweenflange 124 andsecond end 116, and configured to permitsecond end 116 to be inserted at a mounting location. -
Assembly 100 may be mounted within an opening or other mounting location by insertingsecond end 116 through a front face of the mounting location so thatclip arms 120 pass through the opening and engage a rear face of the mounting location.Assembly 100 may be removed by pulling onfirst end 114 in a direction generally opposite the direction of insertion without the user needing to actuate a portion of retainingclip 118 directly, or requiring access to the rear face to depress any portion ofclip arms 120.Assembly 100 can also be removed from the mounting location without the use of any tools. As shown inFIG. 6 ,sides 32 ofbulkhead 34 are captured betweensecond ramps 152 and opposingfaces 130 offlanges 124.Assembly 100 may be held relatively fixed betweensecond ramps 152 and opposingfaces 130, withsecond ramps 152engaging sides 32. Alternatively,assembly 100 may be held more loosely, with some space betweensides 32 andsecond ramps 152 and opposing faces 130. -
Retainer clip 118 is preferably made of a resilient material such as spring steel or a metal of similar properties that will tend to return to its original shape when flexed. Alternatively,spring arms 120 could be formed integrally withhousing 112 and aseparate retainer clip 118 would not be needed. In this alternative, the spring arms and the housing may be made of a plastic or similar molded material which provides the necessary rigidity and strength forhousing 112 and the desired resilient characteristics needed forspring arms 120. - As shown in FIGS. 4 to 7,
adapter 12 is configured to receive LC format fiber optic connectors in each of the first and second ends. It is anticipated that adapters configured to receive different format fiber optic connectors may be used with the present invention. It is also anticipated that adapters which may be configured to receive connectors of different formats in each end may be used with the present invention. - FIGS. 8 to 11
show retainer clip 118 and cliparms 120 including a first ramped portion orramp 150 and a second ramped portion orramp 152. Afirst end 158 offirst ramp 150 is attached or formed integrally with aside 156 and extends fromfirst end 158 to asecond end 160.Second end 160 is also the point of furthest extension away from anouter wall 157 ofside 156.Second ramp 152 is connected to or formed integrally withfirst ramp 150 atsecond end 160, which also defines a point of furthest extension ofclip arm 120 fromside 156.Second ramp 152 extends from point offurthest extension 160 to adistal end 162adjacent side 156. As shown,distal end 162 extends beyond aninner wall 166 ofside 156. Whenretainer clip 118 is placed about ahousing 112,distal end 162 will preferably rest againstside 122 and may be deflected slightly outboard byside 122, asside 122 engagesinner wall 166. As shown in FIGS. 4 to 7,sides 156 ofclip arm 118 andsides 122 ofhousing 112 lie directly adjacent each other and are generally parallel. As shown inFIG. 9 ,clip arm 120 may be formed integrally withside 156 from a portion of material removed to form anopening 164 about three sides ofclip arm 120. -
Second end 160 offirst ramp 150 is deflected out fromside 156 so thatfirst ramp 150 forms an angle with respect toside 156.Second ramp 152 extends from second end and point offurthest extension 160 todistal end 162 at or inboard with respect toside 156. An angle 250 (shown inFIG. 12 ) betweenfirst ramp 150 andside 156 is relatively shallow and engagessides 32 ofbulkhead 34 or other mounting location assecond end 116 is inserted for mounting at the mounting location. Assides 32 engagefirst ramps 150, cliparms 120 are deflected inward to permit second end and point offurthest extension 160 to pass between sides 32. Once second end and point offurthest extension 160 has passed through and beyondsides 32, cliparms 120 are urged to their original undeformed positions.Sides 32 of the mounting opening are captured betweenpoint 160 andinner wall 130 offlange 124, with anouter face 168 ofsecond ramp 152 angled frompoint 160 towardside 122 ofhousing 112. - To remove assembly 100 from within a mounting location such as the opening between
sides 32, a force is exerted onfirst end 114 ofassembly 100. By pulling in a direction generally perpendicular to the opening of the mounting location, sides 32 engageouter face 168 ofsecond ramp 152 and deflectclip arms 120 inward. This moves points 160 close enough tosides 122 to permitassembly 100 be moved from betweensides 32 of the opening and removed from the mounting location. An angle 252 (shown inFIG. 12 ) defined betweenouter face 168 andside 156 of clip arm 120 (and alsoside 122 of housing 112) is preferably steeper thanangle 250. This difference in angles promotes an easier insertion ofassembly 100 into the mounting location and a greater force being required to remove assembly 100 from the mounting location. - It is desirable that
assembly 100 requires a force equal to or greater than about two pounds and up to five pounds to be removed from betweensides 32 of the mounting location. This resistance to removal may be generated by a combination of the physical characteristics of the material from which cliparms 120 are formed and the geometry ofsecond ramp 152 of theclip arms 120. Preferably, the angle ofsecond ramp 152 with respect to side 156 (as shown byangle 250 inFIG. 12 ) orside 122 is between about 19 degrees and about 22 degrees. Preferably, the angle formed byfirst ramp 150 and side 156 (as shown byangle 252 inFIG. 12 ) orside 122 is between about 9 degrees and about 11 degrees. Within these ranges,angle 250 is preferably about 20 degrees andangle 252 is preferably about 10.3 degrees. - When one of the
spring arms 120 is deflected inward,distal end 162 may engagesides 122 ofhousing 112. Ifdistal end 162 does engageside 122 asclip arm 120 is deflected,second ramp 152 may provide additional resistance to deflection and additional resistance to insertion and removal ofassembly 100 from betweensides 32 of the mounting location. Alternatively,clip arm 120 may be formed integrally withside 122 ofhousing 112. To aid in the retention and removal ofassembly 100 betweensides 32 of the mounting location,second ramp 152,distal end 162 is preferably at least flush with an outer face ofside 122 and may be recessed with respect toside 122. -
FIG. 13 shows assembly 100 in position for insertion into a mountinglocation 202 of anadapter mount 200.Adapter mount 200 includes two mountinglocations 202 andassembly 100 is positioned for insertion into the lower mounting location. Adjacent each mountinglocation 202 are opposing sides 204 with a first face 208. Opposite first faces 208 on either side of mountinglocations 202 areapertures 206 for receivingclip arms 120. Asassembly 100 is moved from the position shown inFIG. 12 to the mounted position shown inFIGS. 13 and 14 , first faces 208 engagefirst portions 150 ofclip arms 120 and deflectclip arms 120 inward untiloutermost point 160 passes between sides 204 and intoapertures 206. - Once
assembly 100 has been inserted at mountinglocation 202, as shown inFIGS. 14 and 15 , cliparms 120 return to their non-defected positions withinaperture 206.Outermost point 160 returns to its position defining a width greater than a width defined between sides 204.Outer face 168 ofsecond ramp 152 engages a second face 210 of side 204 whileflange 124 engages first face 208 of side 204. The cooperation of these features holds assembly 100 within mountinglocation 202. Mountinglocation 202 also includes anopening 212 through whichsecond end 116 ofassembly 100 are accessible so that fiber optic connectors may be inserted withinopenings 128. - Removal of
assembly 100 from mountinglocation 202 is effected by exerting a force onassembly 100 to move it from mountinglocation 202 towardfirst end 114. As force is exerted onassembly 100, second faces 210 engageouter faces 168 and deflects cliparms 120 inward so thatoutermost point 160 can slide between sides 204 and out ofapertures 206. Due to the preferable difference in geometry offirst ramp 150 andsecond ramp 152, the insertion ofassembly 100 into mountinglocation 202 should be easier to accomplish than the removal ofassembly 100 from mountinglocation 202. However, as long asassembly 100 provides adequate resistance to removal from mounting location, the relationship of the geometry and shape oframps - The embodiments of the inventions disclosed herein have been discussed for the purpose of familiarizing the reader with novel aspects of the present invention. Although preferred embodiments have been shown and described, many changes, modifications, and substitutions may be made by one having skill in the art without unnecessarily departing from the spirit and scope of the present invention.
