Description

Fiber optic splice organizers

Background of the present invention

1. the field of the invention

The present invention relates generally to the article that can support and gather all interconnection devices, be particularly related to a kind of set part (organizer) or set part inserts, it is suitable for storing a plurality of fibre-optical splices, described inserts have a plurality of arrange can form a plurality of can receiving optical fiber the support arm of groove of joints.

2. the description of prior art

Such as in telecommunication employed like that, people often the end of two optical cables must be coupled together with prolong described fiberoptic cable system, with optical cable in addition branch or repairing damaged optical cable.No matter be aerial optical cable, plow-in optical cable, optical cable, or subterranean cable (cable station or hand-hole) on the ground, people use all boxes to protect all joints usually.Normally one of two types in described all boxes, i.e. in-line arrangement or open joint formula.Adopt in the situation of open joint at optical fiber cable, it all is to adopt a kind of domed shape that several box design are arranged, that is, one is elongated substantially and have a connector box body of a blind end and an open end.In U.S. Patent No. 4,927,227,5,222,183,5,249,253 and 5,278,933 and PCT application No.GB93/00157 in several such designs have been described.

These connector boxs have used that all wire clamps, bolt, optical cable are buckled etc. optical cable is fixed near the open end of described connector box.Can be referring to U.S. Patent No. 5,097,529,5,280,556 and 5,288,946 and PCT application No.US93/05742, GB93/01120 and GB93/01942.These members can provide strain relief to resist because of the move optical cable stress that causes of external cable with respect to described connector box.Being subjected to axial pulling or propelling, twisting or crooked optical cable must accomplish and this motion can not be passed to the cable jacket that is exposed to connector box inside.But, because all including, the design of prior art has the hardware that can damage the sharp edges limit of nuditing fiber and its coating, therefore, they all not too are applicable to optical cable.These designs also need a lot of parts, have therefore increased the cost of connector box, and have also needed specific purpose tool to install sometimes.Owing to used too many interconnecting member, therefore also increased the time of installing.

The optical fiber cable termination of some prior arts has used all shielded joint connector (shield bondconnector) with further fixing described cable sheath, and by using wire sheathing to provide electric continuity as the ground connection sheath.These connectors all have an interior clamping element that is arranged on cable sheath inside usually, with one can grip the outer clamping element that the cable sheath outside surface is stated in the residence, and one is used for making described two members to combine described cable sheath is clamped in bolt or other device therebetween.For example, can be referring to U.S. Patent No. 3,787,797,4,895,525,5,097,529, PCT application No.US94/04198 and Deutsche Bundespatent No.4,231,181.These designs are owing to be unsuitable for handling all intensity members that can run in all optical cables, such as lead or polyarylamide optical cable, so the described cable sheath that they all are unsuitable for being used for optical fiber and copper cable intactly couples together.Really, can be very useful if can have a kind of connector that can easily the copper shield joint be transformed into the optical fiber shielded joint.

In aforesaid several designs, the optical fiber storage support such as adapter bracket be supported by strain relief member or connector box body or be attached thereto.Described storage support generally includes all guide wall so that all optical fiber keeps minimum profile curvature radius.Aforesaid ' 227, ' 183 and ' 253 patents in, and in U.S. Patent No. 5,323,480 and 5, in 363,466, stacked several adapter bracket all are to be articulated in a common pedestal in stepped mode mutually in storage, U.S. Patent No. 5,071,220 and PCT application No.US94/04121 show all in-line arrangement connector boxs, they all have all support that is articulated in a common pedestal in this way.In U.S. Patent No. 5,323, in 478, all supports are with all pin-joint pieces and stacked mutually.These articulated mountings still can allow all optical cables move between the adjacent head bracket thereby turn round hinge when described support is lifted, thereby can make optical fiber produce the microbend loss.Because the geometrical property that ladder had, so they do not utilize the space best yet.

The optical fiber that is routed between all supports usually is to be protected in spiral winding pipe or the cylindrical tube to prevent that all optical fiber is subjected to physical injury and prevents that optical fiber from the bending less than its minimum radius-of-curvature taking place.For cylindrical tube, because all optical fiber must pass described pipe, and for the spirality winding pipe, must around all optical fiber, reel with hand, therefore cylindrical tube and spirality winding pipe all need to expend the considerable time and install, if the length of optical fiber is very long, that is exactly very because of the thing of difficulty.Adopt spiral canoe, when an optical fiber is wrapped, the described optical fiber of also very easy clamping.The optical fiber bifurcated pipe of prior art does not have any effect to the twisting that prevents optical fiber ribbon cable.

All used all the joint carriage (cradle) that can hold a plurality of joint member in several adapter bracket shown in above-mentioned all patents.See also U.S. Patent No. 4,793,681,4,840,449 and 4,854,661.The described feature that holds can directly be molded in the rack surface, as U.S. Patent No. 5,074, disclosed in 635 like that.All joint inserts can be connected in described all supports removably, and all features that holds are the forms that is the flexible cantilever breech lock, cooperate so that can do quick click clatter; To this; Can be referring to U.S. Patent No. 4,489,830,4,679,896 and 5,375,185.If in adjacent grooves, have a lot of members, owing to form the described mobile and cumulative limit that holds the material of feature, so these breech locks can not always be clamped all joint member tightly.Use all joint inserts also can weaken all retaining structures repeatedly or for a long time.In view of the above problems, especially in view of those problems relevant with the connector box that is used for optical cable, people wish to design a kind of fibre-optical splice box with the suitable member that can overcome aforementioned disadvantages.

The description of preferred embodiment

Now see also each accompanying drawing, see also Fig. 1 and Fig. 2 especially, there is shown an embodiment 10 of connector box of the present invention.Though this connector box is particularly suitable for using with optical cable,, describe and a lot of features required for protection as long as slight variations or do not do any variation and just can be used in other application scenarios in addition, such as being used for copper or concentric cable.Usually, all embodiment that disclosed can generally use in the occasion of the optical cable in loop, and it comprises pedestal, case, hand hole, twisted wire pillar or uses on electric pole.These application scenarios can comprise that the video node (videonode) that is used in hybrid fiber/coaxial cable net locates to introduce connector box, the wiring tab box of optical fiber or be used for the fiber-to-the-curb net or the optical fiber of fiber-to-the-home front yard net is introduced connector box.

Connector box 10 generally includes a shell and an inner frame, described shell comprises an elongated dome body 12, described body has one first blind end and one second open end, the one tubular base 14 that links to each other with the open end of described dome body 12, the one breech lock steel wire 16 that is used for body 12 is fixed in releasedly base 14, and a base plate that in Fig. 1, is covered or a strain relief member 18 by pre-stretched tube (PST) 20.Except strain relief member 18, the structure of this shell be used for the copper cash joint, 3M company can reentrant dome connector box (Reenterable Dome Closure) structure be similar.In all accompanying drawings, have two optical cables 22 and 24 to insert connector box 10, but the radical of optical cable can change.In the embodiment that is disclosed, strain relief member 18 has six optical cable mouths that can hold the different optical cable of diameter, and if the diameter of these optical cables less, the optical cable more than can be placed in the independent mouth.

Dome body 12, base 14 and strain relief member 18 can be made by any suitable durable material, but are preferably made such as polyacrylic thermoplasticity (but injection molding) polymkeric substance by a kind of.Described this structure is a kind of distribution piller that is used for open joint.PST 20 is preferably made by a kind of elastic body, such as EPDM, and is collapsed type prestrain in the heart certainly one, and makes its one or both ends to turning up, and promptly reels backward on himself.After all optical cables are fixed in strain relief member 18, base 14 suitable location are being tight against strain relief member 18, with PST 20 be arranged on this two member around discharging its core, even it collapses around base 14 and strain relief member 18 certainly, thereby between their contact interface, form the effect of a kind of waterproof sealing closely.Outside surface along base 14 is provided with all ribs to be meshed with PST20.Also can use such as in U.S. Patent No. 5,258 the gel end seal that is disclosed in 578.After this, with using breech lock 16 that dome body 12 is disassembled from base 14, just can touch the inside of connector box 10, the best breech lock of being made by stainless steel 16 links to each other with base 14 with pin 26 places that described base forms one pivotly at two.All hair clip shapes of breech lock 16 partly are stuck on all respective pins 28 that is formed on the body 12.The choice of location of hair clip shape part and pin 76,28 must make body 12 be against also to form with it on the base 14 sealing function closely, described sealing function can be further enhanced by O shape circle 30, described O shape circle be arranged near base 14 tops, in the ring groove 32 that is formed on the base outer surface.The diameter of described O shape circle 30 and the width of groove 32 are complementary so that a performance enhanced seal effect to be provided.

See also Fig. 3 again, strain relief member 18 of the present invention has adopted a kind of novel designs, and it can provide strain relief for the optical cable (all optical cables) that inserts in the connector box 10, and quick for installation, simple.Strain relief member 18 comprises a flat board 34, and described flat board has several recesses, and described recess takes the shape of the letter U substantially, forms all optical cable mouths 36, and all optical cables can be arranged on strain relief member 18 sides, does not promptly need to make optical cable pass an opening.Described flat board has several outside surfaces 38 between adjacent optical cable mouth 36, these outside surfaces are consistent with the shape of base 14 inside surfaces, therefore strain relief member 18 partly can be arranged on base 14 inside, and have one between surface and the outside surface 38 within it and closely cooperate.Around the root edge that a series of beads that form along outside surface 38 or finger piece 40 tightly are stuck in base 14 to obtain a kind of firm connection effect.Dull and stereotyped 34 also have anchor clamps 42, and described anchor clamps are used for accepting described support, support plate (backplate), terminal block etc., are used for supporting and storing all optical fiber (or electric wire) and relevant interconnection device.In an illustrated embodiment, anchor clamps 42 extend perpendicular to dull and stereotyped 34 substantially, and have one within it and be used for accepting the tang on the described support or the slit of tab.Described slit can be crooked, perhaps for making connection more solid, several additional slot can also be set again.

A part of inside surface of all optical cable mouths is provided with several row projections or tusk 44, and they can be nipped in described cable jacket or the fabricated material so that tighten described optical cable more firmly.Near these tusks, along the inside surface of all optical cable mouths 36, be provided with two can accept all optical cables buckle 48 (referring to Fig. 2 and Fig. 6) with further fixing described optical cable enter slit or opening 46, and two are used for the exit slot 50 that described optical cable is buckled.Each to slit 46 and 50 by being formed on all in optical cable mouth 36 walls from guiding groove and interconnecting.More slit can be set buckle with all the optical cable that is used to add, perhaps only an optical cable is buckled, but two optical cables are buckled and are considered to best.This structure can be installed to most of optical cable on the strain relief member 18 apace with three easy steps.At first, all optical cables are buckled 48 penetrate in the opening 46 and push ahead until have one section sufficiently long length from export extend out 50 till.Then, if desired, by zone to be tightened being wrapped up so that described optical cable is eliminated strain with a kind of suitable fabricated material such as vinyl tape.At last, when described optical cable in an optical cable mouth 36 behind the installation in position, utilize all pliers or an optical cable to buckle rifle and all optical cables are buckled 48 fasten.With all optical cables all fixing like this after, strain relief member 18 is fixed in the base 14, at this moment, all finger pieces 40 tightly are pressed against on the root edge of base 14.Also can use one to prevent that such as those end seals of making by foamed material sealing enters.

Described cable jacket also can further be fixed in the connector box 10, for example, utilizes the conventional clamping apparatus of the device comprise the electric continuity that those can provide cross-over connection ground connection sheath, with cable jacket directly be installed in anchor clamps 42 on supporting member link to each other.If described optical cable also is provided with reinforcement (such as thick metal cords or high strength polyarylamide optical fiber) in addition, the modified shielded joint strain connector 52 shown in Fig. 4 and Fig. 5 also can be used to fix these reinforcements so.Connector 52 has used two the traditional clamping elements 54 and 56 that can fix described cable jacket 58.Interior clamping element 56 has pin or the latch 60 that passes the hole 62 on the outer clamping element 54.All have a plurality of projections or tusk 64 on two clamping elements 54 and 56 to clamp sheath 58.Comprise that an a series of tongue pieces center skewer 66, that be formed on interior clamping element 56 upper ends or skewer are being tight against complementary all skewers 68.

The improvements of connector 52 are two additional member 70 and 72, and this two member is to be used for extending described shielded joint and to provide strain relief for optical cable reinforcement 74.Have three holes 76,78 and 80 in the shielded joint extension 70.Hole 76 is formed in the narrow end 82 of extension 70, and when connector 52 is assembled up (narrow end 82 outside clamping element 54 and outside between the clamping element 56) time can hold bolt 60.Hole 78 holds the skewer 66 of clamping element 56, and described clamping element can be firmly fixed at extension 70 on clamping element 54 and 56 with hole 76.Hole 80 is suitable for holding another and is formed on the bolt 84 that extends on the clamping plate 72, therefore described all reinforcements 74 can be fixed between plate 72 and the extension 70.When being fixed in clamping element 54 its bearing of trend and bolt 60 identical bolts 84 with 56 time, extension 70 can be directly fixed on the supporting member (or anchor clamps) in the connector box 10.One bead 86 that is formed on clamping plate 72 ends can be with a positive stop being provided and further stablizing the described effect that is connected with the frictional fit of extension 70 upper limbs 88.All sides of clamping plate 72 are also in addition crooked, the bead that meshes similarly with all sides that form with extension 70.Can have two indentures in the clamping plate 72, so that all reinforcements can be crossed described clamping plate to the back bending in described all indentures, with the strain relief that obtains to assist, and can be for example additional flange be set with all bent wire of strangulation narrow of extension 70.Clamping plate 72 and extension 70 preferably all are to be made by a kind of metal material, such as aldary, and brass for example, and preferably have one deck tin coating.

Connector 52 has several big advantages.At first, it can handle various types of reinforcements, for example lead or polyarylamide optical fiber.Because all reinforcements and optical cable protective layer opening keep to such an extent that only separate a bit of distance, so it can not allow all reinforcements crooked or curve (for example owing to thermal cycle).This characteristic is useful especially in fiber optic applications.Connector 52 can be connected in various dissimilar existing shielded joint connectors so that the tube shielded joint is transformed into the optical fiber shielded joint.Because near the sheath opening, therefore, can be at an easy rate that it and connector box 10 is interior optical fiber aggregate device insulate mutually and separates with reinforcement terminating for it.At last, because the copper shield joint connector of it and prior art is similar, therefore, concerning the professional, will be fairly simple with the copper transition to optical fiber.

See also Fig. 2 again, the inner frame of connector box 10 can present various forms, but preferably comprises a backboard or transition bracket 92; One or more adapter bracket or then hold in the palm part 94, each adapter bracket all has a cover plate 96; And one or more joint inserts 98 that are used for holding all joints 100, interconnection multifiber 102.Term " joint " typically refers to the permanent interconnection of two transmission lines, and " connector " typically refers to a device that can connect, dismantle and be connected repeatedly if desired again.But because device and the interim device that be connected of the present invention's while to be used in permanent connection, therefore, these terms should not be interpreted as only limiting to those meanings used herein.

Though only show two adapter bracket 94, in the bigger embodiment of connector box 10, more adapter bracket can be set.Clearly show that transition bracket 92 among Fig. 6, described transition bracket is elongated, and at one end has a connecting clamp 104, is used for carrying out removable the connection with the assembling jig 42 of strain relief member 18.Transition bracket 92 has a base plate 106, and on described base plate, be formed with two right cylinders or bobbin 108, they are used for accepting optical fiber reserve piece (optical fiber slack), such as the hypervelocity optical fiber (express fiber) that does not use (connection) at this place.Another arcwall 110 guides to one of them adapter bracket 94 with an optical fiber bifurcated pipe 112.All bobbins 108 and arcwall 110 remain on its minimum profile curvature radius with all optical fiber.All tongue pieces 114 can be used for all optical fiber is remained in the described support.If enough spaces are arranged in dome body 12, fiber optic buffer tube can be wound on to buckle on the base plate outer peripheral edges and with optical cable so and fix.For single pipe, described pipe be stop in the porch and buckle with optical cable and to fix, loose optical fiber then is stored at transition bracket 92 inside.For the hypervelocity ribbon fiber, adopt 8 word modes to store to eliminate all ribbon fibers the twisting phenomenon to occur.Support 92 is preferably enough dark so that can hold the ribbon fiber of a plurality of intersections.One foam block can be connected in the dorsal part of described support 92, and such as being positioned at molded upper bobbin 108 and the cylindrical inside that forms, dome body 12 unloads and all support levels can support all supports when extending when opening with the described connector box of box lunch.Another foam element a such as foam ring (foam donut) can be arranged on around the free end of support or set in advance blind end inside at body 12 so that the performance of anti-vibration and anti-external impact to be provided.

Fig. 7 shows a kind of by-pass tube (split tube) of novelty, and it can be used for all optical fiber is delivered to adapter bracket 94 from transition bracket 92, perhaps delivers to another adapter bracket from an adapter bracket.Similar with prior art, fiber optic cloth spool 116 can be protected all optical fiber in order to avoid be subjected to substantive the damage, and can prevent that optical fiber from bending and less than its minimum profile curvature radius.With cylindrical tube or spiral hold the pipe different, pipe 116 is specially adapted to ribbon fiber; All fibre ribbons fitly are stacked in the inner chamber that xsect is a rectangle, and this shape can prevent all ribbon fiber generation twisting phenomenons.In addition, but with using an interlocking release type seam, hold with cylindrical tube or spiral and compare, it can be installed on all optical fiber more quickly, described seam comprises a vertical keyway 118 that extends and a complementary groove 120 on the total length of described seam.Keyway 118 most advanced and sophisticated extended or be mushroom, complementary groove 120 has the zone that a width reduces, so that the quick cooperation of a bird's nest groove or click clatter one can be provided, therefore can make all wall expansions that form complementary groove 120 and keyway 118 is entered in the complementary groove 120 and along its joint seal fully and lives pipe 116 but the material of making pipe 116 has enough elasticity (such as a kind of EPDM/ polypropylene miser).No matter use which type of pipe, it can both move below the support pivotal point, thereby all optical fiber is freely moved and can not be stuck on any hinge, and can be relaxed to their minimum stress state.

Now see also Fig. 8 and Fig. 9, adapter bracket 94 is essentially identical with the shape and the size of transition bracket 92, and has similar structure, comprise all optical fiber that is used for leading arcwall 122, be used for maintaining the tongue piece 124 of these optical fiber, and be used for tightly clamping the groove 126 of all optical fiber bifurcated pipes.All adapter bracket 94 also preferably have enough degree of depth so that can hold the ribbon fiber of a plurality of intersections.All grooves 126 can have the quick mating feature of a click clatter with fixing all pipes, perhaps buckle with all optical cables and use.All adapter bracket 94 also have one or more base region or recesses 128 that are used for holding all connection inserts 98.One intermediate plate 130 can be set so that can removably adjacent head bracket 94 be fixed on its restoration position on the transition bracket 92, all adapter bracket 94 also can be provided with similar intermediate plate 132.The all stacked tongue piece 134 that is formed on all adapter bracket 94 sides helps to make all supports to pile up neatly.But transition bracket 92 and adapter bracket 94 preferably all are by molded the forming of thermoplastic polymer such as the injection molding of polycarbonate.When with other above-mentioned thermoplastic member (body 12, base 14 and strain relief member 18) when using, definitely without any hardware is to be exposed in the connector box 10, this to store all medium optical cables, the protective metal shell optical cable is comparatively ideal.Connector 52 can wrap up with for example vinyl tape, does not therefore have any exposed metal part.

But the use of injection moulding mold material makes stand hinge mechanism to make one with transition bracket 92 and all adapter bracket 94.Specifically, all trunnions 136 and 138 are formed on the upper surface of transition bracket 92, and similarly trunnion 140 and 142 is formed on the upper surface of all adapter bracket 94.These trunnions are installed in all hubs (hub) of the lower surface relevant position of all adapter bracket.Because these trunnions and hub all are formed in a common terminal place of all supports, therefore can touch them and do not need twisting to be positioned near this end all optical fiber.All hubs have an outer wall, it and have an irregular shape or the outer wall of claw (detent), this claw is to be used for described support deflected into leaving the locational of 60 ° of storage (putting down) inclined position, as shown in Figure 9.All trunnions are enclosed within the socket (socket), and described socket has an inside surface, and have one identical with described hub outer wall irregularly shaped.This feature makes people freely to touch optical fiber in all supports below a last optical fiber with hand, and integrally molded all pins can make all supports pivot, and can twisting or break the optical fiber that enters and pass described support.For an adapter bracket 94 back being moved and aligning with other support, perhaps put down and supporting transition bracket 92, can unclamp described locked mechanism as long as push two buttons 144.

Figure 10 A-10C shows several embodiment of the new-type joint inserts 98 that uses with the present invention.Though inserts 98 is suitable for holding fusion splice or mechanical splice, no matter for discrete type optical fiber or ribbon fiber, they all are suitable for holding similar optical component, such as all unitors, shunt and attenuator.Inserts 98a among Figure 10 A can use with a large amount of fusion splices, and comprise a base or pedestal 146, the shape of described base is corresponding substantially with the shape of all recesses 128 in being formed on all adapter bracket 94, and in preferred embodiment, its shape is rectangular or parallelogram.The all lugs 148 that are formed on the end of pedestal 146 are complementary with the corresponding all recesses of shape that are formed in the adapter bracket 94, thereby help inserts 98a is remained in the recess 128.Can also adopt other method that all pedestals are connected on all supports, such as the pressure sensitive tackifier.Inserts 98a has a plurality of finger pieces or support arm 150a, and these finger pieces are arranged to such an extent that can form the groove cave of series of parallel or groove to hold each joint member.All support arm 150a are interlaced, and all support arm 150a are preferably made by a kind of resilient material so that a multiple spot load to be provided on all joint member, such as natural and synthetic rubber, and polyurethane, EPDM (or with polyacrylic potpourri), neoprene latex or nitrile.All have a flange or uncinus 152 on each support arm 150a, and all uncinuses replace ground towards opposite direction along the given top-cross of a joint member; Therefore, each side of described joint member is provided with among the described embodiment of three support arms, one given joint member be by two at place, its two ends, towards the uncinus of equidirectional, and be positioned at the center, clamping towards rightabout the 3rd uncinus by one.

Figure 10 B shows another kind and is suitable for the joint inserts 98b that uses with the discrete mechanical adapter such as FIBRLOK joint 154 (FIBRLOK is a trade mark of 3M company).Support arm 50b and support arm 150a are similar, but thinner than support arm 150a, and all uncinuses are so unobvious yet.In Figure 10 C, joint inserts 98c is suitable for using with discrete fusion splice member 156, and the xsect of its all support arm 150c is approximately triangle, and has lacked an inferior horn to form described uncinus feature.Two layer scattering fusion splices can be stacked in all grooves of inserts 98c so that its capabilities double, thereby can hold 12 adapter pieces in described embodiment.

The present invention no longer needs to resemble and need be used to be shifted the additional reduced pressure zone of rubber the joint inserts of prior art, and avoided because of eliminating the tolerance increase problem that these reduced pressure zones bring, thereby can also reduce the overall dimension of described inserts, and can strengthen and balanced joint member on stopping function power.This is by providing all support arms that are crisscross arranged to realize, described all support arms also are flexible, and its hardness is preferably in the 60-80 Shore A scope, and is more preferably about 70 ShoreA in 30 Shore A to 50 Shore D scope.The structure of inserts 98a-98c is convenient to the described joint member of dismounting, and can not damage all optical fiber of described joint member or interconnection.
