Description

Cable guide
The invention relates to a cable guide comprising: a passage for guiding at least a portion of at least one cable between a proximal end and a distal end of said passage, and - at least one cable tie for mounting said cable to said cable guide .
US 6,134,370 discloses a fibre optical cable guide for removable placement on a fibre optical cable. The cable guide comprises extensions configured to wrap around at least a portion of the cable. The cable can be released from the cable guide by pulling the cable such that it is freed from the extensions . The cable guide has a first end with a hook portion for attaching the cable guide to a boot of the fibre optical cable. However, the cable guide according to the prior art comprises several limitations with regard to installability in the field, such as a significant danger of damage or breakage of the optical fibres when pulling the cable out of the rigid extensions of the cable guide and limited flexibility with regard to flat fibre optical cables.
It is an object of the invention to provide a cable guide with an improved field installability.
This object is achieved by providing a cable guide characterised in that said at least one cable tie is movable with respect to said cable guide for releasably attaching said cable to said cable guide. Preferably the cable tie comprises a hinged member or a releasable member or a rotating member, which member can be moved or replaced, with respect to the cable guide. By providing such a cable tie the passage of the cable guide can be made available for accommodating or releasing a cable, such as a flat fibre optical cable. During such an operation, no substantial pulling forces have to be applied to the cable and therefore chances of damage or breakage of the optical fibres of the cable are substantially reduced. In a preferred embodiment of the invention the passage of the cable guide is curved. Such a cable guide may e.g. be used for routing or re-routing of the cable. It is well known that fibre optical cables are susceptible to mechanical stress in that the signal transmission quality may significantly decrease if these stresses are too high. However, optical cables need to be guided or routed in various directions in spaces that are often severely limited or restricted, such as behind a backpanel . As a result significant curvature or bending of these optical cables is often unavoidable. The curve of the passage thus may not have a curvature beneath the minimum bend radius resulting in significant degradation of the cable.
In a preferred embodiment the cable guide comprises a housing at the proximal end providing a further passage for the cable that is substantially aligned with the passage of the cable guide. This housing may be adapted to be mounted to a connector. The housing and/or cable guide may comprise hinging means for making available the passage or passage and further passage for said cable.
It should be appreciated that the embodiments, or aspects thereof, may be combined.
The invention also relates to a cable comprising a cable guide as described above. Cables may be provided, with cable guides that are releasably mounted to these cables by the cable tie means, as a result of which a guide or routing direction does not have to be decided upon prior to installing the cable. Moreover, re-routing of cables is less complex. These cables may e.g. be flat fibre optical cables. The invention also relates to a method for guiding a cable using a cable guide as described above .
The invention also relates to a method for guiding a cable from a first direction to a second direction using a cable guide as described above, comprising the steps of: - releasing said cable pointing in said first direction from said cable tie; orienting said cable guide or a second cable guide such that said distal end points in said second direction; attaching said cable by said cable tie in accordance with said passage .
. The embodiments of the invention will be described into more detail below with reference to the attached drawing of which
Figs . 1A-H show a cable guide according to an embodiment of the invention in various stages of use;
Fig. 2 shows a backpanel wherein various cable guides are employed; Figs. 1A-H show a cable guide 1 according to an embodiment of the invention in various stages of use.
As shown in Fig. 1A a cable guide 1, that may comprise parts 1' and 1", comprises a passage 2 extending between a proximal end 3 and a distal end 4, and a housing 5 (see Fig. IC) . Housing 5 is located at the proximal end 3 of the passage 2. Housing 5 comprises a first part 6 and a second part 7 that are connected via hinging means 8. In Fig. 1A housing 5 is shown in an opened state . Housing 5 provides a further passage 9 substantially aligned to the passage 2. The cable guide 1 comprises a cable tie 10 connected via a hinge 11. It is noted that the cable tie 10 can alternatively be connected to the cable guide 1 as a rotating member, wherein the passage 2 can be made accessible or available by first moving cable tie 10 in the z-direction and afterwards e.g. rotate the cable tie 10 substantially in the x-y plane. In yet another alternative the cable tie 10 is adapted to be entirely released from the cable guide 1. The cable tie 10 may be closed by applying locking means 12, such as a pin adapted to co-operate with the cable tie 10. The entire cable guide 1 may be closed and locked by employing the locking means 13.
It is noted that alternatively the part 1" may alone constitute the cable guide and that the cable tie function is performed by the part 1' for releasably attaching a cable. In such a case the cable tie 1' is movable via the hinging means 8 with regard to the cable guide 1" providing the passage 2. The cable tie 1' can be locked by employing the locking means In Fig. IB a cable guide 1 is shown, wherein the hinging means 8 are located in a different position compared to the embodiment shown in Fig. 1A. Fig. IC shows a closed cable guide 1. The handling member 14 can be used for e.g. pushing the cable guide during installation.
Fig. ID shows a cable guide 1 as shown already in Fig. 1A, but yet with a cable 15 attached. Cable tie 10 is employed to attach the cable 15 to the cable guide 1. According to an aspect of the invention the cable 15 can be attached to the cable guide 1 without prior knowledge of the preferred direction, for cable tie 10 is adapted to easily release and subsequently attach again the cable 15 to the cable guide 1 in the preferred direction.
Fig. IE shows the situation wherein the cable guide 1 is closed by employing the hinging means 8 while having a cable 15 attached. The curve of the passage 2 is such that it does not have a curvature beneath the minimum bend radius that results in significant degradation of the cable 15. Cable 15 is represented here as a flat fibre optical cable. In Fig. IF housing 5 is shown in abutting position against a connector 16 of cable 15. The connector 16 comprises a body 17 containing a ferrule with guide pins 18. Housing 6 is adapted to be mounted to the connector 15, by e.g. closing housing 5 using the hinging means 8 and subsequent mechanical locking to the connector 16.
In Figs. 1G and 1H the situation is shown wherein the bent cable guide 1 is employed to guide the cable 15 in a first direction 19 and a second direction 20. According to an aspect of the invention the cable 15 can be easily re-routed from the first direction 19 to the second direction 20 by releasing the cable 15 from the cable guide 1 by employing the cable tie 10.
In Fig. 2 a backpanel 21 is shown with MPO connectors comprising coupling sleeve means 22. The coupling sleeve means 22 have been provided with a plurality of cable guides 1, none of them comprising a cable 15 here. The distal ends 4 of the cable guides 1 point in various directions. As a result,, cables 15 may be guided or routed in these various directions by employing these bent cable guides 1 without degradation of the cable caused by severe bending. Note that in Fig. 2 only the passages 2 of the cable guides 1 are visibly and that other cables guides are shown on the backpanel 21 as well. MPO connectors (not visible) with mounted cable guides 1 are inserted into the housings 23 of the back panel 21, wherein the handling means 14 can be used.
For the purpose of teaching the invention, preferred embodiments of the cable guide have been described above. It will be apparent for the person skilled in the art that other alternative and equivalent embodiments of the invention can be conceived and reduced to practice without departing from the true spirit of the invention, the scope of the invention being only limited by the claims.
