Definitions
- the invention relates to a device for receiving splice cassettes for optical waveguides, especially in cable sleeves.
- a disadvantage with the known solution is that individual cassettes cannot be individually adapted to the different installation requirements, the device cannot be used in a variety of systems with different cassettes, and necessary reserve cable cannot readily be accommodated in the known cable sleeve.
- the invention allows a single design of device to be used with ease in a variety of applications irrespective of the type of cassettes used.
- the present invention provides a device for housing splice cassettes for optical waveguides, comprising a receiving housing and splice cassettes arranged therein preferably in manner of drawers, and co ⁇ prising openings for the entry and exit of optical waveguides, cable conductors or the like, characterised in that the splice cassettes are arranged on cassette carrying plates which are located in the receiving housing in such a manner that they can be slid and/or rotated, preferably by simply pushing or pulling by hand, in and out.
- the cassette carrying plates In the construction of the invention, provision is made for the cassette carrying plates to be provided with fixing elements in order to form coiled reserves of cable in addition to the coiled reserves of cable on the cassettes.
- 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 corrpletely 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- in position, so that if a housing is in an inclined position, for exa ⁇ ple, when work is being carried out, the cassettes that are not being worked on are prevented from falling out even if further pulled-out positions are fixed, for exa ⁇ ple the half pulled-out position or the virtually completely pulled-out position, the locking being effected in such a manner that complete removal of that individual cassette carrying plate from the housing is also made possible. Catches, slide elements or the like can be provided in this case.
- a potential equalising plate for the fixing of the shields of the incoming and outgoing cables to be assigned to the housing in the position of use in order to equalise the potential, as is also provided by the invention.
- the invention is suitable in principle for every kind of housing, both for a switch cupboard and for cable sleeves, one especially advantageous arrangement of the housing being within a so-called butt closure, formed for exa ⁇ ple from a dome-ended sleeve, that is to say, the cassette carrying plates lie one beside another in the longitudinal direction in an upright position.
- 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 mounted on the base plate or side plate of the sleeve.
- the housing may be manufactured from a wide variety of materials, one possibility being to construct at least regions of it from profiled sheet metal.
- Fig. 1 is a sirtplified three-dimensional view of a base plate of a pot sleeve with the device according to the invention
- Fig. 2 is a side view approximately according to arrow II in Fig. 1
- Fig. 3 is a side view approximately according to arrow III in Fig. 1
- Fig. 2 is a side view approximately according to arrow II in Fig. 1
- Fig. 3 is a side view approximately according to arrow III in Fig. 1
- Fig. 2 is a side view approximately according to arrow II in Fig. 1
- Fig. 3 is a side view approximately according to arrow III in Fig. 1
- Fig. 4 is a side view of a cassette outside the housing with incoming and outgoing conductor bunches.
- a housing designated 3 is fastened by means of upright feet 4 inside a pot sleeve, generally designated 1, on which the actual pot, which is fastened to a base plate designated 2, is not shown in Fig. 1.
- the upright feet 4 carry a rotationally symmetrical housing made of profiled sheet metal parts 5 to 7 which, as shown in Fig. 2, are so arranged in relation to one another that compartments are formed into which the cassette carrying plates designated 8, which carry the cassettes designated 8a, are inserted in the manner of drawers.
- the elements 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 bunches or the like entering and leaving the splice cassettes are formed at the lower edge with the neighbouring wall.
- the incoming and outgoing optical waveguides and conductor bunches are generally designated 11 in the Figures, irrespective of whether they are bunches of many or few conductors or are single cable conductors or the like.
- each cassette carrying plate 8 has a plurality of clamping projections 12 behind which the incoming and outgoing fibre bunches or cables 11 can be laid in large reserve loops in such a manner that, for exa ⁇ ple in Fig. 4, downwardly oriented loops 11a are formed which, however, depending upon the position of the cassette 8, could also be formed at the top.
- a so-called potential equalising plate 13 to which all the shields of the incoming and outgoing cables may be connected for the purpose of equalising the potential.
- an earthing cable (not shown) can also be contacted there.
- the described embodiment of the invention can, of course, still be modified in many respects without departing from the underlying concept.
- the invention is not limited to a pot sleeve design and a horizontal arrangement can be provided in the same manner, for exa ⁇ ple in a through-sleeve, there may be many different spacings between adjacent cassette carrying plates, and so on.
