Description
W 095/lOOS9 PCT/GB94/02082 Descri~tion Device for receiving splice cassettes for optical waveouides, e~eciallY in cable sleeves The inv~nti~n relates to a device for receiving splice cassettes for optical waveguides, especially in cable sleeves.
Various designs of splice cassettes are kncwn, for example fram EP-A-0 288 808, EP-A-O 531 628, DE-B-0 216 073, EP-A-0 101 970 or fram the two German laid-open specifications 34 05 309 and 34 13 401.
It is also kncwn to stack a plurality of such cassettes one above another in cable sleeves, as is disclosed, for example, in PCT/GB
92/02350 of the ~pllr~nt, in which the individual cassettes are stacked one above another, located in d~L~liate guides and fastened to one another, for example ky a central screw arrangement. A device that forms the generic type is known from EP-A0 204 581.
A disadvantage with the known sslllti~n is that individual cassettes car~lot be individually adapted to the different inst~ t;~n requirements, the device cannot be used in a variety of systems with different cassettes, and necessary reserve cable cannot readily be ~ccnmm~te~ in the kn3wn cable sleeve.
The inv~nti~n allows a single ~ n of device to be used with ease in a variety of ~plic~t-~n~ irrespective of the type of cassettes used.
Thus, the present invention provides a device for housing splice cassettes for optical waveguides, ccmprising a receiving housing and splice cassettes arranged therein preferably in manner of drawers, and comprising openings for the entry and exit of ~optical waveguides, cable conductors or the like, characterised in that the splice cassettes are auL~lged on cassette carrying W 095/10059 ~ ~ 7 ~ 3 4 8 - 2 - PCT/GB94/02082 plates which are located in the receiving housing in such a m~nner that they can be slid and/or rotated, prefera~hly by simply pushing or pulling by hand, in and out.
With the device according to the invention, it is possihle by using the cassette carrying plates which can be moved in the manner of drawers to em~loy the same construction in different systems for electronic data tr~n~mi~s;~n te~hni~ues, which makes it easier to m~nllf~ture the latter econ~mic~lly.
In the construction of the invention, provision is made for the cassette carrying plates to be provided with fixing PlPm~ntS in order to form coiled reserves of cable in addition to the coiled reserves of cable on the cassettes.
As a result of this pos~ihility of providing a place for hln~he.
or a place for cables on the cassette carrying plates in addition, it is ~o~.sihle to m~nipulate the cassettes at a relatively great distance from a sleeve equipped in that m~nner, since because of the additional coiled reserves the cassette itself can be removed from the device and placed, for example, on a work-bench.
In c~ L~ction, provision is made according to the invention for a ~L~k~L~ion of the cassette carrying plates which can be pushed into the housing to be s~ti~lly offset in the housing from another proportion of the push-in cassette carrying plates, so that h~n~l;ng is again made easier, since different positi~ning spaces are produced for the necessary reserve loops of the in~ming and olltgo;n~ optical waveguides.
In addition to the ~os.~;hility of e~ in~ the housing with frontal fastening PlPmPnt.~ for msunting purposes, the invention also provides that the cassette carrying plates are guided in the housing in the manner of drawers, it being possible to fix at least the c~m~let~ly pushed-in position and/or the pulled-out position by a catch or the like, that is to say, each cassette carrying plate is advantageously held individually in its pushed-WO9S/10059 _ 3 2 1 7 ~ 3 4 8 PCT/GB94/02082 in position, so that if a housing is in an in~linP~.7 position, forexample, when work is being carried out, the cassettes that are not being worked on are prevented from f;711ing out even if further pulled-out positions are fixed, for e ~ nple the half pulled-out position or the virtually completely pulled-out position, the locking being effected in such a m~nner that complete re7noval of that individual cassette carrying plate from the housing is also made pos.~ih1e. C;7t~ , slide elements or the like can be provided in this case.
It is also advantageous for a potPnt;~1 eql7~ ;n~ plate for the fixing of the shields of the in~min~ and outgoing cables to be ~ign~ to the housing in the position of use in order to e~ e the potPnt;~l, as is also provided by the invention.
The invention is suitable in pr;n~;p1P for every kind of housing, both for a switch ~1pho~rd and for cable sleeves, one especially advantageous arrangement of the housing being within a so-called butt closure, formed for e~nple from a dome-ended sleeve, that is to say, the cassette carrying plates lie one hPsi~P another in the longit1l~;n~1 direction in an upright position. For that purpose, the invention provides that, in order to arrange the housing in an upright position inside a pot sleeve with cables entering and leaving at one end, the housing is equipped with supporting feet which can be m~unted on the base plate or side plate of the sleeve.
The housing may be m~mlfactured from a wide variety of materials, one p~ihility being to con~struct at least regions of it from profiled sheet metal.
The invPnt;~n is described in detail by way of e~nple below with reference to the drawings in which:
-Fig. 1 is a simrlified three-~impn~;onal view of a base plate of a pot sleeve with the device according to the invention, Fig. 2 is a side view appro~;m~tPly according to arrow II in Fig. l, ~ ~ 7 - 4 - PCT/GB94/02082 Fig. 3 is a side view appro~im~t~ly according to arrow III in Fig. 1, and Fig. 4 is a side view of a cassette outside the housing with ;n~ming and outgoing conductor bunches.
, A housing designated 3 is fastened by means of upright feet 4 inside a pot sleeve, generally ~ci~n~ted 1, on which the actual pot, which is fastened to a base plate ~ign~t~ 2, is not shown in Fig. 1. In the example shown, the upright feet 4 carry a rot~ti~n~1ly symmetrical housing made of profiled sheet metal parts 5 to 7 which, as shcwn in Fig. 2, are so arranged in r~l~ti~n to one another that compdLL~ Ls are formed into which the cassette carrying plates designated 8, which carry the cassettes ~ci~n~ted 8a, are inserted in the m~nner of drawers.
In the example shown, the ~l~m~ntc of the receiving housing 3 are equipped at their lower edge with flanges 9 which form drawer-runners for the cassette carrying plates 8, the shape being such that slot openings 10 for the passage of the optical waveguides, cable h mrh~s or the like entering and leaving the splice cassettes are formed at the lower edge with the neighb3uring wall. The in~m;ng and olltg~in~ optical waveguides and conductor hln~h~c are generally designated 11 in the Figures, irrespective of whether they are h m~h~c of m~ny or few conductors or are single cable conductors or the like.
As will be seen, for example, from Fig. 3 and Fig. 4, each cassette carrying plate 8 has a plurality of ~l~m~ing projections 12 h~hin~ which the in~ming and outgoing fibre hln~h~ or cables 11 can be laid in large reserve loops in such a manner that, for example in Fig. 4, downwardly oriented loops lla are formed which, however, depending upon the position of the cassette 8, could also be formed at the top.
As will be seen especially from Fig. 1, there is ~Csi~n~ to the device 3 a so-called potential ~ licin~ plate 13 to which all W o 95/10059 PCT/GB9~/02082 ~ - 5 - 2171348 the shields of the ;nc~mi~ and outgoing cables may be connected for the purpose of ~lAl;cin~ the potential. If desired, an earthing cable (not shcwn) can also be contacted there.
The described en~xxl~nent of the invention can, of course, still be mo~ifie~ in m~ny respects withc~t departing from the underlying concept. For example, in partic~ r, as has already keen m~nti~ne~ above, the invention is not limited to a pot sleeve ~ n and a hori~nt~l arrangement can be provided in the same m~nner, for example in a through-sleeve, there may be many different s~;n~ between adjacent cassette carYying plates, and so on.
Various designs of splice cassettes are kncwn, for example fram EP-A-0 288 808, EP-A-O 531 628, DE-B-0 216 073, EP-A-0 101 970 or fram the two German laid-open specifications 34 05 309 and 34 13 401.
It is also kncwn to stack a plurality of such cassettes one above another in cable sleeves, as is disclosed, for example, in PCT/GB
92/02350 of the ~pllr~nt, in which the individual cassettes are stacked one above another, located in d~L~liate guides and fastened to one another, for example ky a central screw arrangement. A device that forms the generic type is known from EP-A0 204 581.
A disadvantage with the known sslllti~n is that individual cassettes car~lot be individually adapted to the different inst~ t;~n requirements, the device cannot be used in a variety of systems with different cassettes, and necessary reserve cable cannot readily be ~ccnmm~te~ in the kn3wn cable sleeve.
The inv~nti~n allows a single ~ n of device to be used with ease in a variety of ~plic~t-~n~ irrespective of the type of cassettes used.
Thus, the present invention provides a device for housing splice cassettes for optical waveguides, ccmprising a receiving housing and splice cassettes arranged therein preferably in manner of drawers, and comprising openings for the entry and exit of ~optical waveguides, cable conductors or the like, characterised in that the splice cassettes are auL~lged on cassette carrying W 095/10059 ~ ~ 7 ~ 3 4 8 - 2 - PCT/GB94/02082 plates which are located in the receiving housing in such a m~nner that they can be slid and/or rotated, prefera~hly by simply pushing or pulling by hand, in and out.
With the device according to the invention, it is possihle by using the cassette carrying plates which can be moved in the manner of drawers to em~loy the same construction in different systems for electronic data tr~n~mi~s;~n te~hni~ues, which makes it easier to m~nllf~ture the latter econ~mic~lly.

As a result of this pos~ihility of providing a place for hln~he.
or a place for cables on the cassette carrying plates in addition, it is ~o~.sihle to m~nipulate the cassettes at a relatively great distance from a sleeve equipped in that m~nner, since because of the additional coiled reserves the cassette itself can be removed from the device and placed, for example, on a work-bench.

In addition to the ~os.~;hility of e~ in~ the housing with frontal fastening PlPmPnt.~ for msunting purposes, the invention also provides that the cassette carrying plates are guided in the housing in the manner of drawers, it being possible to fix at least the c~m~let~ly pushed-in position and/or the pulled-out position by a catch or the like, that is to say, each cassette carrying plate is advantageously held individually in its pushed-WO9S/10059 _ 3 2 1 7 ~ 3 4 8 PCT/GB94/02082 in position, so that if a housing is in an in~linP~.7 position, forexample, when work is being carried out, the cassettes that are not being worked on are prevented from f;711ing out even if further pulled-out positions are fixed, for e ~ nple the half pulled-out position or the virtually completely pulled-out position, the locking being effected in such a m~nner that complete re7noval of that individual cassette carrying plate from the housing is also made pos.~ih1e. C;7t~ , slide elements or the like can be provided in this case.
It is also advantageous for a potPnt;~1 eql7~ ;n~ plate for the fixing of the shields of the in~min~ and outgoing cables to be ~ign~ to the housing in the position of use in order to e~ e the potPnt;~l, as is also provided by the invention.
The invention is suitable in pr;n~;p1P for every kind of housing, both for a switch ~1pho~rd and for cable sleeves, one especially advantageous arrangement of the housing being within a so-called butt closure, formed for e~nple from a dome-ended sleeve, that is to say, the cassette carrying plates lie one hPsi~P another in the longit1l~;n~1 direction in an upright position. For that purpose, the invention provides that, in order to arrange the housing in an upright position inside a pot sleeve with cables entering and leaving at one end, the housing is equipped with supporting feet which can be m~unted on the base plate or side plate of the sleeve.
The housing may be m~mlfactured from a wide variety of materials, one p~ihility being to con~struct at least regions of it from profiled sheet metal.
The invPnt;~n is described in detail by way of e~nple below with reference to the drawings in which:
-Fig. 1 is a simrlified three-~impn~;onal view of a base plate of a pot sleeve with the device according to the invention, Fig. 2 is a side view appro~;m~tPly according to arrow II in Fig. l, ~ ~ 7 - 4 - PCT/GB94/02082 Fig. 3 is a side view appro~im~t~ly according to arrow III in Fig. 1, and Fig. 4 is a side view of a cassette outside the housing with ;n~ming and outgoing conductor bunches.
, A housing designated 3 is fastened by means of upright feet 4 inside a pot sleeve, generally ~ci~n~ted 1, on which the actual pot, which is fastened to a base plate ~ign~t~ 2, is not shown in Fig. 1. In the example shown, the upright feet 4 carry a rot~ti~n~1ly symmetrical housing made of profiled sheet metal parts 5 to 7 which, as shcwn in Fig. 2, are so arranged in r~l~ti~n to one another that compdLL~ Ls are formed into which the cassette carrying plates designated 8, which carry the cassettes ~ci~n~ted 8a, are inserted in the m~nner of drawers.
In the example shown, the ~l~m~ntc of the receiving housing 3 are equipped at their lower edge with flanges 9 which form drawer-runners for the cassette carrying plates 8, the shape being such that slot openings 10 for the passage of the optical waveguides, cable h mrh~s or the like entering and leaving the splice cassettes are formed at the lower edge with the neighb3uring wall. The in~m;ng and olltg~in~ optical waveguides and conductor hln~h~c are generally designated 11 in the Figures, irrespective of whether they are h m~h~c of m~ny or few conductors or are single cable conductors or the like.
As will be seen, for example, from Fig. 3 and Fig. 4, each cassette carrying plate 8 has a plurality of ~l~m~ing projections 12 h~hin~ which the in~ming and outgoing fibre hln~h~ or cables 11 can be laid in large reserve loops in such a manner that, for example in Fig. 4, downwardly oriented loops lla are formed which, however, depending upon the position of the cassette 8, could also be formed at the top.
As will be seen especially from Fig. 1, there is ~Csi~n~ to the device 3 a so-called potential ~ licin~ plate 13 to which all W o 95/10059 PCT/GB9~/02082 ~ - 5 - 2171348 the shields of the ;nc~mi~ and outgoing cables may be connected for the purpose of ~lAl;cin~ the potential. If desired, an earthing cable (not shcwn) can also be contacted there.
The described en~xxl~nent of the invention can, of course, still be mo~ifie~ in m~ny respects withc~t departing from the underlying concept. For example, in partic~ r, as has already keen m~nti~ne~ above, the invention is not limited to a pot sleeve ~ n and a hori~nt~l arrangement can be provided in the same m~nner, for example in a through-sleeve, there may be many different s~;n~ between adjacent cassette carYying plates, and so on.
