Definitions

  • the present invention relates to the formation of optical fibre mechanical splices, and particularly relates to a tool and a kit for facilitating the quick and reliable assembly of an optical fibre connector.
  • the invention provides a tool for holding and manipulating at least part of an optical fibre connector, the tool comprising a shank having holding means at a first end thereof opposite a second end thereof, by which holding means an optical fibre connector or part thereof may be held, and a sleeve at least partly surrounding the shank, wherein the sleeve is retractable with respect to the shank between an extended position in which the sleeve extends along at least part of the shank at least as far as the holding means thereby to protect a connector or connector part held by the tool in use, and a retracted position in which the holding means is more exposed thereby to facilitate the attachment or removal of the connector or part thereof to, or from, the holding means.
  • the invention has the advantage that because the tool includes a sleeve at least partly surrounding the shank which can extend at least as far as the holding means, an optical fibre connector (or a connector par) held and manipulated by the tool may be protected by the sleeve. Even more advantageously, however, because the sleeve is retractable, the attachment of the connector (or connector part) to the tool, or its removal from the tool, is facilitated.
  • the sleeve in its extended position, extends along at least part of the shank and beyond the holding means.
  • the holding means is exposed.
  • the sleeve is slidable along the shank continuously between its intended and retracted positions.
  • the tool is arrange to facilitate a protected and reliable attachment of an optical fibre connector part held by the tool, to a connector body of an optical fibre connector.
  • a second aspect of the invention provides a kit comprising a tool according to the first aspect of the invention, and a support for an optical fibre connector body, wherein the sleeve of the tool is arranged to fit with the support such that an optical fibre connector part held by the tool in use may be attached to a connector body held by the support, by retraction of the sleeve with respect to the shank of the tool.
  • the sleeve of the tool is substantially rigid.
  • the sleeve may be formed from metal (e.g. steel) or a plastics material, for example.
  • the sleeve preferably forms a sliding fit around at least part of the shank of the tool, preferably between its extended and retracted positions. More preferably, the sleeve is biased to adopt its extended position by means of a resiliently compressible component of the tool. In order to adopt its retracted position, the sleeve preferably must be urged against the resilience of the resiliently compressible component. Consequently, in its relaxed state the sleeve preferably adopts its extended position.
  • the resiliently compressible component preferably comprises a spring, more preferably a helical spring, advantageously located around the shank of the tool.
  • the tool includes a handle, and more preferably the handle is located at the second end of the shank (i.e. at the opposite end to the holding means).
  • the holding means of the tool may generally comprise any means suitable for holding an optical fibre connector part.
  • the holding means comprises one or more elongate holding members (preferably a plurality of elongate holding members).
  • the elongate holding members are arranged to interlock (preferably via an axial sliding fit) with elongate members of a connector part which the tool is specifically arranged to hold and manipulate.
  • the kit according to the invention preferably includes one or more optical fibre connector parts which the tool (and more especially the holding means) is specifically arranged to hold and manipulate.
  • the or each connector part is a holder/ferrule assembly as described and illustrated herein.
  • the sleeve of the tool preferably is arranged to fit with a support for an optical fibre connector body such that an optical fibre connector part held by the tool may be attached to a connector body held by the support, by retraction of the sleeve with respect to the shank of the tool.
  • attachment is carried out by moving the shank, and therefore the holding means, of the tool towards the connector body held by the support while the sleeve (which has been fitted to the support) remains substantially motionless relative to the connector body and the support but is retracted with respect to the shank. Consequently the connector part held by the tool is attached to the connector body held by the support in a controlled and protected manner within the sleeve of the tool.
  • an end of the sleeve which extends at least as far as the holding means (when the sleeve is in its extended position) is arranged to fit with the support.
  • the fit is a mating fit.
  • the end of the sleeve has a generally flared shape.
  • a corresponding part of the support is generally frusto-conical in shape, such that the (female) flared end of the sleeve is arranged to form a mating fit with the (male) frusto- conical part of the support.
  • the connector part held by the tool may be securely attached to the connector body held by the support by means of a bayonet-style attachment (or the like). Consequently, once the connector part has formed an initial attachment to the connector body (e.g. by simple axial insertion), the shank of the tool preferably is twisted (i.e. rotated about its axis) thereby to secure the connector part to the connector body.
  • the sleeve of the tool includes an open slot extending along at least part of its length from the end of the sleeve (which is preferably flared) in order to allow an optical fibre extending from a connector part held by the tool to extend out of the sleeve.
  • the shank includes a corresponding slot for the same purpose.

Between the sections 3' and 3" is a frusto-conical transition section 4 of the bore.
  • the narrow diameter section 3" of the axial bore extends from a front end 5 of the ferrule 1, and the wide diameter section 3 ' extends from a rear end 7 of the ferrule 1.
  • the circumferential external surface 8 of the ferrule includes a pair of diametrically-opposed projections 9, the purpose of which will be explained below.
  • the circumferential external surface includes a circumferential N-groove 11 which may be used, for example, in an optical fibre cleaving tool for positioning the ferrule with respect to a cleaving mechanism when the ferrule is fixed to an optical fibre extending through the ferrule.
  • Figure 1 does not show an important aspect of the ferrule 1, namely a part of the circumferential external surface of the ferrule which causes the ferrule to be receivable in a connector body of a connector according to the invention in only a single pre-set orientation about the axis of the ferrule.
  • this feature is shown in Figure 4, and comprises a cut-away flat surface part 15 of the circumferential external surface 8 extending from the front end 5 of the ferrule.
  • Figure 2 shows schematic top and side views of two ferrules 1 according to the invention having optical fibres 13 extending therethrough.
  • both ferrules 1 (which are identical to each other) have such a cut-away flat surface part 15 of their circumferential external surface 8 which is at a fixed orientation with respect to a cleaved non-perpendicular end face 17 of the respective optical fibre 13 extending through the ferrule. This was achieved as follows.
  • An end section of an optical fibre 13 had its buffer jacket stripped to expose the primary coating, and the end of the fibre was threaded through the axial bore 3 of a ferrule 1 from the rear end 7 until the buffer jacket of the fibre abutted the transition section 4 of the bore. A sufficient length of the buffer jacket of the optical fibre 13 was stripped to ensure that a significant length of the stripped fibre extended from the front end 5 of the ferrule 1.
  • the ferrule 1 (containing the fibre 13) was then inserted into a crimping and cleaving tool which is the subject of a co-pending UK patent application of the present applicant. The tool was used firstly to crimp a rear section for the ferrule 1 (i.e.
  • the tool was used to cleave a portion of the optical fibre extending from the front end 5 of the ferrule, such that a non-perpendicular end face 17 of the fibre was produced.
  • the cut- ay flat surface part 15 of the ferrule 1 was used in the tool to orient the ferrule (about its axis) with respect to the cleaving mechanism of the tool, such that the non-perpendicular cleaved end face 17 of the fibre has a pre-set orientation with respect to the fiat surface part 15 of the ferrule 1. Because the ferrule is firmly crimped in place on the fibre, this pre-set orientation is a fixed orientation.

  • the connector body 19 has a hollow, generally cylindrical shape and preferably is formed from polymer and/or metal, preferably PPS (polyphenylene sulphide) containing a glass filler.
  • the connector body 19 has an elongate aperture 21 extending axially throughout its entire length between opposite open ends 23 and 25. Each open end 23, 25 is arranged to receive a respective ferrule 1 in a single pre-set orientation about the axis of the ferrule, with respect to the connector body.
  • each of two opposite end sections of the aperture which are intended to receive respective ferrules 1 having a cross-sectional shape corresponding to the external circumferential shape of a front portion of a ferrule 1, with a flat surface part (not shown) corresponding to the flat surface part 15 of the ferrule and arranged at a position (around the axis of the connector body 19) so as to achieve a desired orientation of its respective ferrule 1.
  • the two ferrules 1 received by the connector body 19 are substantially identical to each other, and therefore the flat surface parts of the aperture 21 preferably are situated on diametrically opposite sides of the aperture 1 from each other, in order to provide a relative orientation between the two ferrules as shown in the "Top view" of Figure 2.
  • the two opposing ferrules 1, when received in the aperture 21 of the connector body 19 preferably are arranged such that their front ends 5 face each other and their orientations about their axes (which are coaxial with the aperture 21) are diametrically opposed.
  • the non-perpendicular cleaved end faces 17 of the optical fibres (to which the ferrules 1 are fixed) have been formed in an identical way, such that their orientations relative to their respective ferrules are identical, then mere insertion of the two ferrules in the connector body 19 results in a correct opposing orientation of the two end faces 17 (as shown in Figure 2), so that an intimate contact between the two end faces over substantially their entire surfaces is possible.
  • the aperture 21 narrows at frusto-conical transition regions 29 to provide a narrow central region of the aperture 21.

  • the tool 48 comprises a handle 51 from which a central elongate shank and a surrounding protective elongate sleeve 53 extend.
  • the end of the central shank of the tool 48 (not shown in detail) opposite to the end attached to the handle 51 has elongate holding members which are arranged to interlock (via an axial sliding fit) with the elongate members 48 of the holder 39 of the assembly 40, so that the assembly 40 may be held and manipulated by means of the tool.
  • the elongate protective sleeve 53 has an open slot 54 extending along at least part of its length from a flared open end 55 of the sleeve, in order to allow the optical fibre 13 extending from the rear end 47 of the holder 39 to extend out of the sleeve 53, as shown in views (b) and (c) of Figure 5.
  • the protective sleeve 53 is retractable with respect to the central shank of the tool, in a direction towards the handle 51.
  • a helical spring 56 Between the handle 51 and the sleeve 53 is a helical spring 56 which, in its relaxed state, causes the sleeve to adopt an extended position away from the handle 51 such that it surrounds and extends beyond the ferrule/holder assembly 40 held by the shank of the tool.
  • the tool is arranged such that when the sleeve 53 is in its fully extended position the sleeve extends beyond, and therefore protects, the exposed cleaved optical fibre 13 extending from the front end 5 of the ferrule 1 of the assembly 40. In this way, the cleaved optical fibre end section is protected from damage during manipulation of the assembly prior to its insertion in the connector body 19.

  • View (b) of Figure 5 shows the subsequent operation whereby the handle 51 of the tool 48 is pushed forwards towards the connector body 19 as indicated by arrow A. This motion of the handle causes the central shank of the ool, and hence the ferrule/holder assembly 40 held by the shank, to move towards the
  • the protective sleeve 53 of the tool remains motionless relative to the connector body 19 and the support 50, but it is retracted (by compression of the helical spring 56) relative to the shank and the handle 51 of the tool, as indicated by arrow B. Consequently the ferrule 1 and the cleaved end 17 of the optical fibre 13 to which the ferrule is fixed are inserted in a controlled and protected manner into the connector body 19.
  • each holder 39 includes a resiliently compressible member (as shown, a spring 41) situated between the respective ferrule 1, and the rear retaining wall of the holder.

  • the first of the two ferrule/holder assemblies 40 to be pushed onto the connector body 19 i.e. the assembly 40 already attached to the connector body, as shown in Figure 5) is immediately secured to the connector body 19 by twisting the tool 48 (and hence the holder 39 of the assembly 40) with respect to the connector body 19 so that slots 43 of the holder 39 interlock with lugs 42 in a bayonet-style attachment.
  • the holder 39 When the holder 39 is twisted with respect to he connector body 19 it is also twisted with respect to the ferrule 1 which it holds, because the ferrule has been inserted into the connector body and is unable to rotate due to its keyed orientation in the connector body (i.e. due to the corresponding flat surface parts of the ferrule 1 and the connector body 19).
  • This twisting motion of the holder 39 with respect to its ferrule 1 causes the projections 9 at the rear end of the ferrule to dig into the material of the holder 39 (which preferably is formed from a plastics material, more preferably PBT, i.e. polybutylene teraphthalate) so that the ferrule is locked in position axially with respect to the holder.
  • the resiliently compressible spring member 41 of the assembly will accommodate any so-called "fibre repel" between the fibres to be spliced. Fibre repel may occur due to cleavage tolerances, and results from the combined length of exposed fibre between the two ferrules being too great. This is accommodated by the resiliently compressible spring member 41 of the second assembly 40 compressing to allow the ferrule 1 of the second assembly to move rearwardly away from the opposite ferrule, so that a good splicing contact between the two optical fibres may be achieved. The resilience of the spring member 41 ensures, however, that there is a good contact between the cleaved end faces of the fibres.
