Description

Dome case for the optical fiber use

Technical background of the present invention

1. the field of the invention

The present invention relates generally to a kind of cover box that mechanical protection and storage are provided for the cable that uses in the telecommunication for example; be particularly related to a kind of ground case for the optical fiber use; tagblock and connector, this case have hinged optical fiber storage disks and the guiding fiber passes pipe from a fiber that coils another dish.

2. the introduction of prior art

In telecommunications engineering, usually need the end of two cables is coupled together, to prolong cable system, tell additional cable, or repair impaired cable.Usually no matter use the cover box to protect the junction, be aloft, directly embedding, on the ground or at underground (inserting hole or inspecting hole).This cover box often be two types, the series connection or the butt joint in a kind of.In the optical fiber cable of butt joint, some cover boxes are designed to dome-shaped, and promptly housing generally is elongated, has a blind end and an openend.United States Patent (USP) the 4th, 927, No. 227, the 5th, 222, No. 183, the 5th, 249, No. 253 and the 5th, 278, No. 933, and PCT application GB93/00157 has described some this structures.

These cases use various clips, screw rod, and frenulums etc. are fixed on cable near the openend of case.See United States Patent (USP) the 5th, 097, No. 529, the 5th, 280, No. 556 and the 5th, 288, No. 946, and PCT application US93/05742, GB93/01120 and GB93/01942.These parts are for providing strain relief by external cable relative to the cable stress that case moves generation.Axially spurred or promotion, knot or crooked cable must not be transferred to this motion cable cover(ing) opening in case.Yet structure of the prior art seldom is applicable to optical fiber cable, because they comprise the metal parts with sharp edges, these sharp edges may be damaged the fiber of exposure and their coating.These structures also need many annexes, thereby have increased the cost of case, and also need special instrument to install sometimes.The use of many interconnected parts has also additionally increased the set-up time.

Cable termination uses the shielding joint connector in some prior aries, so that utilize metal tape additional fastening cable sleeve, and provides the electrical continuity across the ground connection sheath.These connectors generally have the outer clamping element that an interior clamping element and that is installed in the cable sleeve inboard is caught the cable cover(ing) outside surface, and a screw rod and or other device so that force two clamping elements together sheath to be clipped in the middle.For example, see United States Patent (USP) the 3rd, 787, No. 797, the 4th, 895, No. 525 and the 5th, 097, No. 529, No. the 4th, 231,181, PCT application US94/04198 and Deutsche Bundespatent.These structures are not suitable for realizing again being used for the integrality of the cable cover(ing) of optical fiber and copper cabling because (for example) they can not suitably handle the strength member that in optical fiber cable, can see, such as tinsel or aramid fibre.Really, it is very useful having connector, because this will allow to be attached to from the copper cash shielding the convenient conversion of fiber shielding combination.

In above-mentioned several structures, the optical fiber storage disks, such as patching panel by strain relief or over body case supporting or fixing.Storage disks generally includes the guide wall that makes fiber keep minimum bending radius.At above-mentioned the 4th, 927, No. 227, the 5th, 222, No. 183 and the 5th, 249, in No. 253 patents, and United States Patent (USP) the 5th, 323, No. 480 and the 5th, 363, in No. 466, some patching panels that are superimposed together in storage process are hinged on the common base plate with the stair step form.United States Patent (USP) the 5th, 071, No. 220 and PCT application US94/04232 has shown the tandem case, they have the dish that is hinged on by this way on the common base plate.At United States Patent (USP) the 5th, 323, in No. 478, dish is superimposed together by hinged band.These articulated structures still allow fiber to move between adjacent patching panel, thereby knot can occur when the lifting dish, cause the microbend loss in the fiber.And since the geometry of stair step, the space that they also can the most advantageously not use.

The fiber that is directed between dish usually by spiral winding pipe or cylindrical tube protection, is subjected to mechanical damage to prevent fiber, and hinders the minimum bending radius of the bending of fiber less than it.Cylindrical tube and spiral winding pipe will be installed with a certain amount of time, this be because, for cylindrical tube, fiber must pass through this pipe, and twines for spiral, twines and must manual be coiled on the fiber, very long as fruit fiber, this may be difficult.When using spiral to twine, when parcel, also be easy to clamped fibers.Fiber of the prior art passes pipe at all can not prevent the ribbon-like fibre excessive distortion.

Several patching panels that show in above-mentioned patent use the tagblock support of the many tagblock parts of supporting.See United States Patent (USP) the 4th, 793, No. 681, the 4th, 840, No. 449 and the 4th, 854, No. 661.These keep function directly to be molded on the panel surface, and as United States Patent (USP) the 5th, 074, No. 635 disclosed.The tagblock socket can be fixed on the dish with being disassembled, and it has with pliable and tough cantilever latch form carries out the maintenance function that clamping is installed, and sees United States Patent (USP) the 4th, 489, and No. 830, the 4th, 679, No. 896 and the 5th, 375, No. 185.If many parts are arranged in adjacent groove, keep moving of materials with function to increase owing to form with tolerance, these breech locks are not always clamped the tagblock part securely.The tagblock socket repeatedly and long-time use also may cause the function of keeper to die down.From all these problems, particularly, preferably provide a kind of optical fiber case to overcome above-mentioned restriction with suitable part with the relevant problem of using for optical fiber cable of case.

Dome body 12, bottom 14 and strain relief 18 can be by durable materials, preferably use the thermoplastic polymer (injection moldable) such as polypropylene to form.Structure described here is a kind of ground case that is used to splice.PST20 is preferably by elastic body, form such as EPDM (ethylene-propylene-diene rubber), and is contained in advance on the folding fuse, and outwards overturn in its one or two end, promptly be wrapped in backward from one's body.After cable is fixed on the strain relief 18, bottom 14 suitably is resisted against on the strain relief 18, and around these two parts installation PST20 and the fuse release that makes wherein, it is folded around bottom 14 and strain relief 18, thereby forms a firm waterproof sealing along their interphase.Some ribs are arranged, so that mesh with PST20 on the outside surface of bottom 14.Also can use such as United States Patent (USP) the 5th, 258 No. 578 described gel end sealings.Then, by unloading the inside that dome body 12 can enter case 10 from the bottom 14 that utilizes clamping tinsel 16.Clamping tinsel 16 (preferably stainless steel) is pivotably mounted on two pins 26 that are formed at bottom 14.The hair clip shape part that clamps tinsel 16 be formed at dome body 12 on 28 clampings of corresponding pin.Select the position of hair clip shape part and the position of pin 26 and 28, make dome body 12 be forced to be resisted against on the bottom 14, and between them, form a firm sealing, sealing also can further be strengthened by an O type circle 30, and this O type circle 30 be installed in one near 14 upper ends, bottom, be formed at 32 li of the annular groove of bottom on 14 outside surfaces.The diameter of O type circle 30 cooperates with the width of groove 32, so that improved sealing to be provided.

Referring to Fig. 3, strain relief 18 of the present invention has been used the structure of a novelty below, and it provides strain relief for the cable that enters case 10, and can carry out simple fast the installation.Strain relief 18 comprises a plate 34, and it has some openings, roughly is the U type, forms cable passage 36, and allows cable from laterally being installed on the strain relief 18, that is, do not need to make cable pass the hole.This plate has some outside surfaces 38 between adjacency channel 36, and they are identical with the shape of bottom 14 inside surfaces, so strain relief 18 can partly be installed in the bottom 14, and closely cooperates between 38 on its inside surface and surface.38 series of flanges that form or protrusion 40 are around the lower limb closure of bottom 14, so that firm connection surfacewise.Plate 34 also has sectional fixture 42, so as the admittance dish, back plate, terminal block etc., its supports and stores each fiber (or tinsel) and relevant interconnect device.In described embodiment, sectional fixture 42 is generally perpendicular to plate 34 and extends, and has a slot, so that be received in the tang on the dish or connect a sheet.This slot can be bent, or for additional slot fixedly is provided more firmly.

The part of the inside surface of passage is provided with the outstanding and tooth 44 of several rows, and they snap in cable sleeve or assembled material, so that catch cable more firmly.Near these teeth, there are two to enter slot or opening 46 along the inside surface of passage 36, they accept cable tie 48 (seeing Fig. 2 and 6), so that further attached cable, and two outlet slots of using for frenulum 50.Relevant a pair of slot 46 is connected by the bootstrap groove that is formed in passage 36 walls with 50.Can provide more slot for other cable tie usefulness, perhaps have only one, but two are considered to best.This structure allows in three steps a large amount of cables to be quick installed on the strain relief 18.At first, make cable tie 48 pass opening 46 and promote it, until there being enough length to extend through outlet slot 50.Then, if necessary, by with a suitable fabricated material, be wrapped in clamped place such as the vinyl plastics band, making cable is that strain relief is got ready.At last, when cable is positioned at 36 li in a passage, utilize a pliers or a cable tie rifle to tighten frenulum 48 firmly.After all cables were so fixing, with strain relief 18 bottom 14 of packing into, wherein, protrusion 40 was compressing the lower limb of bottom 14 firmly.Can use one such as the end seal of making by polyfoam, so that water-proof function to be provided.

In addition, by directly being fixed on the supporting member that is installed on the anchor clamps 42, can further cable sleeve be fixed in the case 10, this can use traditional clamp device, and those devices that can provide across the electrical continuity of ground connection sheath are provided.If strength member (such as heavy wire or high tenacity aramid fibers) is provided extraly for cable, so, the improved shielding shown in the Figure 4 and 5 can be used to fix these strength members in conjunction with strain connector 52.Connector 52 uses two traditional clamping elements 54 and 56, is used for fixing cable sleeve 58.Interior clamping element 56 has a pin or screw rod 60, and it is passed in the hole 62 on the outer clamping element 54.Two clamping elements 54 and 56 have many tang or tooth 64, so that clamp sleeve pipe 58.A series of tab clamping element 56 upper ends, that comprise center prong 66 or prongs of being formed at match with complementary prong 68.

The improvement of connector 53 is to prepare two additional parts 70 and 72, and they are used for extending the shielding combination, and strain relief is provided for cable strength member 74.Shielding has three holes 76,78 and 80 in conjunction with extension 70.Hole 76 is formed on the narrow end 82 of extension 70, and assembling accept during connector 52 screw rod 60 (narrow end 82 interior clamping element 54 and outside between the clamping element 56).The prong 66 on the clamping element 56 is accepted in hole 78, and prong 66 is used to together extension 70 added securely in company with hole 76 and is connected on clamping element 54 and 56.Hole 80 is suitable for accepting to be formed at extending another screw rod 84 on the clamping plate 72, strength member 74 can be fixed between plate 72 and the extension 70 thus.When extension 70 being added when being connected on clamping element 54 and 56, screw rod 84 extends along the direction identical with screw rod 60, and screw rod 84 can directly be fixed on the supporting member (or sectional fixture) in the case 10.Be formed at flange 86 on clamping plate 72 ends by reliable braking being provided and can further stablizing this connection with the frictional fit of the coboundary 88 of extension 70.The side 90 of clamping plate 72 also is bent and forms flange, and they similarly mesh with the side of extension 70.Clamping plate 72 can have two recesses, make strength member can above this plate backward bending enter in this recess, the strain relief for additional also can provide additional flange, for example on the narrow of extension 70, so that the tinsel of about beam bending.Clamping plate 72 and extension 70 preferably use the metal material such as aldary to make, and for example brass preferably has tin coating.

Connector 52 has some advantages.At first, it can be used for the strength member of any kind of, for example tinsel or aramid fibre.Its not crooked or distortion (for example, because the circulation change of temperature) of proof strength part is because they remain on from the short distance of cable cover(ing) opening.This feature is meaningful especially in optical fiber is used.Connector 52 can be fixed on dissimilar existing shielding joint connectors, so that shield combination from copper cash in conjunction with being transformed into fiber.Because it stops strength member near ferrule openings, therefore, it can be isolated with the fiber controller of 10 li of cases easily.At last, because it is similar to copper cash shielding joint connector of the prior art, therefore for the skilled person, the conversion from the copper cash to the fiber will be eaily.

Referring again to Fig. 2, the interior framework of case 10 can adopt various forms, but preferably comprise a back card/back board or transition disc 92 and one or a few patching panel 94, patching panel 94 respectively has cover plate 96 and one or several tagblock socket 98, and the tagblock socket is used for admitting the tagblock 100 that is connecting many optical fibers 102.Term " tagblock " usually relates to the permanent connection between two transmission lines, and different with " connector " that comprise the device that can be connected, separate, connect (repeating if desired) usually.But,, therefore, just should not use the restrictive sense here to explain these terms because the present invention can similarly be used for the device and the provisional device that is connected of permanent connection.

Though only drawn two patching panels 94, in the embodiment of big case 10, also can use more patching panel 94.Transition disc 92 is preferably referring to Fig. 6, and it is elongated, at one end has a stationary fixture 104, can removably be connected with the sectional fixture 42 on the strain relief 18.Transition disc 92 has base plate 106, is formed with two cylinders or bobbin 108 on it, so that admit the wire turn of optical fiber reserve piece, does not for example use the extrusion fiber (express fiber) of (connection) on this position.Another arcuate walls 110 passes pipe 112 with a fiber and guides to a patching panel 94.Bobbin 108 and wall 110 make optical fiber keep the bending radius of a minimum.Teat 114 can be used to make fiber retention in dish.If enough spaces are arranged in dome body 12, the separator tube fiber can be wound on the periphery of plate, and fixes with cable tie.For single pipe, this pipe ends at import and fixes with cable tie at this, and loose fibres is stored in 92 li of transition discs.For the extruding ribbon-like fibre, store any knot that to eliminate belt in 8 font modes.Transition disc 92 preferably has the degree of depth of the belt that can hold multiple intersection.One foam-plastic blocks can be fixed on the rear side of dish 92,,, and flatly stretch all dishes so that opening case, supporting all dishes when promptly unloading dome body 12 such as in molded upper bobbin 108 formed cylinders.Another piece polyfoam can be installed around the free end or the precalculated position in the blind end of dome body 12 of dish such as a ring-shaped foam body, so that the ability of vibration proof and external impact is provided.

Fig. 7 has described a kind of new Ying's division formula pipe 116, and it can be used to guide fiber from transition disc 92 to patching panel 94, or from a patching panel to another patching panel.Identical with goods of the prior art, fiber guide pipe 116 can prevent that fiber is subjected to mechanical damage, prevents fiber bending extremely less than its minimum bending radius.Different with cylindrical tube or spiral winding, pipe 116 is particularly suitable for ribbon-like fibre; Article 12, fabric strip fitly is stacked on the inboard that xsect is a rectangle, and this shape does not allow the belt distortion.In addition, by using interlocking, and the threaded off seam of forming by vertical spline 118 that extends along the total length of seam and complementary groove 120, can mode be installed on the fiber with twining faster than cylindrical tube and spiral.Spline 118 is extended or one-tenth mushroom-shaped at its top, and groove 120 has the zone of a reduced width, so that provide a dovetail groove or clamping to cooperate, but the material of pipe 116 has enough elasticity (such as EPDM/ polypropylene mixture), wall expansion with the groove 120 that allow to form, allow spline 118 to enter groove 120 fully, and along its joint seal pipe 116.No matter use which type of pipe, it can move below the pivotal point of dish easily, so that allow fiber freely to move, and can not be stuck at any turning point place, and can make them lax to minimum stress state.

Referring now to Fig. 8 and 9,, the patching panel 94 preferably total shape and size with transition disc 92 is identical, and has similar structure, comprises the arcuate walls 122 that guides fiber, keeps the teat 124 of fiber and the guide groove 126 that about bundle fiber passes pipe.Patching panel 94 preferably also has the degree of depth of the belt that is large enough to hold multiple intersection.Guide groove 126 can have the clamping function, so that (or use with cable tie) fixes this pipe.Patching panel 94 also has one or several filling area or recess 128 of admitting tagblock socket 98.One intermediate plate 130 can be set on transition disc 92,, and on the patching panel 94 identical intermediate plate 132 can be set so that releasedly adjacent patching panel 94 is fixed on its storage location.The bonding jumper 134 that is formed at patching panel 94 sides helps the neatly superimposed of all dishes.Transition disc 92 and patching panel 94 are preferably with the thermoplastic polymer of injection moldable, make such as polycarbonate.When using other thermoplastic component recited above (dome body 12, bottom 14 and strain relief 18), have metal parts anything but and be exposed in the case, this storage and metal sheathed cable for all insulated cables is desirable.Connector 52 can wrap up with (for example) vinyl plastics band, thereby does not have the metal of exposure.

Use injection molding material also to allow linkwork with transition disc 92 and patching panel 94 integrally formed dishes.Specifically, make pivot pin 136 and 138 be formed at the upper surface of transition disc 92, and similarly pivot pin 140 and 142 is formed at the upper surface of patching panel 94.These pins cooperations are installed in the sleeve that is positioned at accordingly on patching panel 94 lower surfaces.Because these pins and sleeve shaped are formed on the same end of all dishes, so they can pass in and out (inclination) and not need the fiber twisting together and be directed around this end.Sleeve has the outer wall with irregularly shaped or pallet, so that dish is biased into the position of 60 ° of relative storage (straight) inclined position, as shown in Figure 9.Pivot pin is socketed in the socket, and this socket has an erose inside surface identical with sleeve outer wall.This feature allows hand freely near the fiber in the dish below the top, and integrally moulded pin permission dish pivots and can knot or fracture and enter and leave the fiber of dish.For mobile patching panel 94 backward, it is alignd with other dish, or straight ground transition disc 92 relatively, can promote two buttons 144 so that locking mechanism discharges.

Embodiment some new Yings, that be used for tagblock socket 98 of the present invention is shown in Figure 10 A-10C.Though socket 98 is suitable for admitting tagblock fusion or machinery, for discontinuous or banded fiber usefulness, they are equally applicable to admit such as similar optical element such as unitor, separation vessel and attenuator.Socket 98a shown in Figure 10 A can use with many fusion tagblocks, and it comprises a base plate or backing plate 146, and backing plate 146 has and the depression 128 overall corresponding shape that are formed on the patching panel 94, and in preferred embodiment, it is rectangle or parallelogram.The lug 148 that is formed at backing plate 146 ends be formed at patching panel 94 on the corresponding breach of shape cooperate so that socket 98 is installed in 128 li of depressions.Other means also can be provided, backing plate be fixed on the dish such as pressure-sensitive adhesive.Socket 98a has many finger pieces or support 150a, owing to their position forms the jack or the groove of series of parallel, so that admit each tagblock part.Support 150a is staggered, so that butted line piece part provides the multiple spot load, they are preferably made by resilient material, such as natural or synthetic rubber, and polyurethane, EPDM (or with polyacrylic mixture), neoprene or nitrile rubber.Each support has flange formed thereon and hook 152, along the hook of a certain side of tagblock part alternately towards reverse direction; Like this, shown in embodiment in, provide three supports in each side of tagblock part, catch a certain element in its end face to unidirectional two hooks, and catch the central part of element towards rightabout the 3rd hook.

Figure 10 B has described another tagblock socket 98b, and it is applicable to discontinuous mechanical tagblock, such as FIBRLOK (trade mark of 3M company) tagblock 154.Support 150b is similar to support 150a, but they are thinner than support 150a, and its hook is unconspicuous.In Figure 10 C, tagblock socket 98c is suitable for using with discontinuous fusion tagblock part 156, and the xsect of its support 150c almost is leg-of-mutton, and does not have following angle to form the hook function.Two-layer discontinuous fusion tagblock can be stacked in the groove of socket 98c, makes its capabilities double, shown in embodiment in can place 12 parts.

The present invention has eliminated the needs of tagblock socket of the prior art additional release areas for mobile rubber, and the problem of having avoided the tolerance relevant to increase with eliminating these release areas, reduced the overall dimension of socket thus, strengthen and balance act on maintenance energy on the tagblock element.This obtains by staggered support is provided, and these supports are pliable and tough, has in the hardness of 30 Shore A in the 50 Shore D scopes the preferably hardness in 60-80 Shore A scope, preferably about 70 Xiao A hardness.The structure of socket 98a-98c is that the insertion and the taking-up of tagblock all is easier to, and can not damage the fiber of element or interconnection
