Abstract
A distributor for optical cable connections, such as those for connections of cables containing fibre optics comprises the incoming transmission line 1 within which is sheathed several optical fibre 7 housed within transmission line duct 2 that is detachably retained in the distributor 4 by insertion into the slide-in adaptor 3 and so for the purposes of in-service revision to the fibres enables temporary access to the optical fibre 7.
Description
<p>Distributor for Optical Cable Connections The present invention relates
to the field of distributors for optical cable connections, such as those for connections of cables containing fibre optics where one or more fibres within an incoming transmission line cable housed within a transmission line duct then break out the individual optical fibres within the distributor for routing within discrete tubing or sheathing for the outgoing transmission line. Such arrangements of distributor are known; in particular a UK Patent GB 2166563 B describes such a device. This prior art declares a distributor having two body portions, the first body portion retaining plastic tube enclosed incoming transmission line and the second body portion housing discrete plastic sleeved outgoing transmission line, the two body portions are retained within a cover member and the said tubes are fixedly retained by adhesive bonding or by mechanical or other means to the body portions. An optical fibre manifold as declared in the prior art of UK Patent GB 2292010 B also describes a device for the break out of individual fibres from a multi-fibre bundle carried by a single cable element tube wherein following fibre placement within the body it is locked closed, thereby preventing further access to inlet and outlet channels.</p>
<p>The present invention overcomes a primary problem with both these examples of the prior art and the known field in that because of the fixed retention and closure of the component parts it is not practicable to make any revisions to the transmission line, for example an upgrade to increase capacity, change in bandwidth or change in mode from single to multimode.</p>
<p>The present invention provides a distributor for optical cable connections primarily but not exclusively manufactured from plastic mouldings. It is composed of an anchor plate for retention of said distributor to a predefined surface, a base that is attachable to said anchor plate by moulded in plastic clips, a tray that is attachable to said base by moulded in plastic clips, a slide-in adaptor for receiving the transmission line duct in which runs the incoming transmission line cable that is locked into the tray by fore and aft plastic clips, one or more sub-assemblies of crimp inner, crimp outer and rubber boot for retention of the individual optical fibres of the outgoing transmission line, this configuration of parts may then be closed by clipping on the lid that is attachable to said tray by moulded in plastic clips or alternatively by utilising another second said configuration stacked on top and thereby attaching to the first tray by moulded in plastic clips of the second tray.</p>
<p>The retention of the transmission line duct is by insertion into the slide-in adaptor, the preferred method of retention being through use of a commonly available, generically named "Press-in Fitting" where in angled metal barbs concentric to a circular transmission line duct prevent withdrawal of said transmission line duct by partial local penetration of metal barbs into the duct circumference. This provides a reversible fixture because the barbs may be withdrawn by pressing upon a collet, thus with this arrangement access to the interior of the transmission line duct and so also to the transmission line cable can be made.</p>
<p>Alternatively the detachable location of the transmission line duct to the adaptor may be achieved by use of a compression fitting or other mechanical means.</p>
<p>The transmission line duct is commonly, but not limited to, generally circular tube of a diameter in the range 3mm to 16mm.</p>
<p>Following the user's revision to the fibres within the transmission line duct the distributor is returned to the original format by re-insertion of the transmission line duct into the slide-in adaptor. Access to the entry end of the outgoing transmission line may also be made by un-clipping the lid or stacked distributor and subsequently lifting the associated rubber booted crimp assembly out of the tray.</p>
<p>The present invention therefore resolves the said problem of the prior art by providing a distributor that enables temporary access to the optical fibre for revision purposes such as upgrade to increase capacity, change in bandwidth or change in mode from single to multimode.</p>
<p>One embodiment of a distributor according this invention is now described by reference to the drawings for which; Figure 1 provides an isometric view of an assembled distributor with cabling.</p>
<p>Figure 2 provides an exploded view of the distributor.</p>
<p>Figure 3 provides an isometric view of an assembled distributor without cabling.</p>
<p>Figure 4 provides an isometric view of booted stripped back fibre.</p>
<p>Figure 5 provides an isometric view of booted stripped back fibre with crimped inner.</p>
<p>Figure 6 provides an isometric view of stacked lower and upper assembled distributors.</p>
<p>For a distributor requiring revision to the transmission line, for example an upgrade to increase capacity, change in bandwidth or change in mode from single to multimode then temporary access to the optical fibres within the distributor is necessary.</p>
<p>Figure 1 comprises the incoming transmission line 1 within which is sheathed several optical fibre 7 housed within transmission line duct 2 that is detachably retained in the distributor 4 by insertion into the slide-in adaptor 3. The various outgoing transmission line 6 exit the distributor 4 via rubber boot 5.</p>
<p>Figure 2 provides in exploded view the component parts of the distributor 4. The transmission line duct 2 is shown concentrically in line with the collet 8 and 0 ring 9 and barb carrier 10. When the transmission line duct 2 is inserted into the slide-in adaptor 3 concentric to it also locates the collet 8 and 0 ring 9 and barb carrier that fit within the slide-in adaptor 3 and utilising the 0 ring 9 seal between the outside diameter of the transmission line duct 2 and the inside diameter 11 of the slide-in adaptor 3. The barb carrier 10 also provides retention of the transmission line duct 2 by locally indenting into the outer surface of the transmission line duct 2. By pushing the collet 8 into the slide-in adaptor 3 a temporary withdrawal of the barbs of the barb carrier 10 is effected which enables the transmission line duct 2 to be withdrawn from the distributor 4. This action enables access to the optical fibre 7 housed within transmission line duct 2.</p>
<p>The slide-in adaptor 3 locates to the tray 14 by alignment and insertion of locators 12 into cores 13. The tray 14 is clipped to the base 17 by way of moulded in tray female clip 22 to base male clip 16. The anchor plate 18 may be screwed to any suitable surface, usually the interior of a cabinet, by screwing via anchor plate holes 21. The base 17 is clipped to the anchor plate 18 by fore anchor plate clip 19 and rear anchor plate clip 20. Thus by a sequence of polymeric clips and screws in the anchor plate the tray 14 is fixed in position. Into the outlet side of the distributor locates one or more rubber boot 5 into which fit the transmission outlet line 6. Rubber boot 5 is located into the tray 14 that also houses a crimp inner 24 and a crimp outer 25, for purposes of access to the optical fibre 7 these may be temporarily lifted out for revision to the fibre layout.</p>
<p>The lid 26 clips to the tray 14 by way of male tray clip 15 to female lid clip 27.</p>
<p>This arrangement comprises the component parts of this embodiment of the invention.</p>
<p>Figure 3 provides an isometric view of an assembled distributor 4 without cabling, where in the tray 14 is clipped using lower tray clip 29 to the base 17 and also upper tray clip 28 to the lid 26.</p>
<p>In Figure 4 two examples of the transmission outlet line 6 are shown fitted with rubber boot 5. A portion of the transmission outlet line 6 projects through the rubber boot 5 with the stripped end of the transmission outlet line 6 providing retention elements 30.</p>
<p>In Figure 5 the retention elements 30 are shown folded back along the crimp inner 24. The crimp outer 25 is slid over the inner crimp 24 thereby trapping the retention element 30 and eftecting secure retention of the transmission outlet line 6 to the tray 14 when this sub assembly of components is placed into the outlet end of the tray 4.</p>
<p>Figure 6 shows an alternative configuration where in place of using a lid 26 to close off the top of the lower distributor 31 a stacked distributor arrangement is created by clipping the upper distributor 32 onto the lower distributor 31. This arrangement may also be repeated sequentially so that a stack of more than two distributor 4 is enabled.</p>
