a 1 Abstract Universal sleeve with longitudinally divided sleeve tube and sealing bodies at its end faces.

The invention is a cable sleeve consisting of a longitudinally divided sleeve tube (MR) having a sealing system on its longitudinal side and sealing bodies (DK) at its end faces. The sealing bodies (DK) have at least one projecting entry fitting at least one of the entry fittings (ES) having two longitudinal divisions made in the direction of the longitudinal axis. Uncut cables can be introduced, even subsequently, through the sealing body sector cut-outs (DKS1, DKS2, DKS3) which o thus arise. The seal between the entry fitting (ES) and the cable introduced in each case is made with a diameter-compensating seal element, preferably with heatshrinkable objects.

0000 0 oua 0 oD 0 04 0 0 0D0 0 The invention relates to a cable sleeve consisting of a longitudinally divided sleeve cylinder having a sealing system on its longitudinal side and sealing bodies at its end faces, in which sealable entry holes are arranged.

German Patent 2,427,677 discloses sealing bodies consisting of plastic for cable sleeves of the abovementioned type. The necessary entry holes for cables are cut in according to requirements and with the necessary -15 diameter. Sealing occurs with the aid of a plastic sealing compound. Since the entry holes are arranged there along the dividing plane of the sealing body, only a few entries per side of the cable sleeve are possible.

Furthermore, the diameter must be matched and cut to the cable to be inserted in each case taking into account the introduced sealing compound in each case. In addition, special pull-relief devices for the cable are to be provided since, as a. result of the plastic sealing compound, a movement can occur in the sealing area when ,25 the cable is subjected to tensile and compression loading.

0440 0 0 a 0 4 t II It is the object of the invention to provide a universal sleeve with which an uncomplicated diameter matching is possible, it being intended to make easier the clamping of the cable while maintaining the already known advantages of such cable sleeves. The present object is now achieved witih a cable sleeve of the type described at the beginning in that at least one of the sealing bodies has at least one projecting entry fitting, in that preferably one of the entry fittings has two longitudinal divisions made in the direction of the longitudinal axis as far as the sealing body so that in each case two complementary sealing body sector cut-outs L I I A V 2 I 2 are formed, in that seals are arranged in the longitudinal dividing planes of the entry fitting and of the sealing body and in that diameter-compensating seal element is arranged at" the free end of each entry fitting.

The advantages of the cable sleeve according to the invention are to be seen particularly in the fact that, seen as a whole, with the simplest type of installation in the entry areas, further problems relating to the mechanical clamping, the diameter transition between entry holes and cable are also solved in a simple way.

Furthermore, it is advantageous that subsequent changes in an entry area can also be made whilst the remaining seals of the same sealing body remain unaffected by this.

0 15 With the sealing elements in the form of heat-shrinkable o hoses or collars on the entry fittings, in addition 0 0 branchings can also be made so that, also in this way, an advantageous variant is produced. Moreover, the cable entries, hitherto known per se, according to the state of the art mentioned at the beginning can also be integrated into the entry systems according to the invention, which means that, in addition to the entry fittings, entry holes with matched diameters can also be cut into the o0o0 sealing bodies. For example, it is particularly suitable .01:0o25 initially to make conventional entry holes and then in the event of later extensions to use the entry holes in o the entry fittings according to the invention. In this way, the original sealing areas can remain unaffected since the new entry holes and seals are made separately according to the invention.

The invention is now explained in greater detail with reference to twenty figures listed below: Figure 1 shows a cable sleeve according to the invention in section.

Figure 2 shows an exemplary embodiment of a first sealing body sector cut-out.

Figure 3 shows the sealing body sector cut-out which completes the exemplary embodiment according to Figure 2.

0000 0 0 o °'°25 0r 00 Figure Figure 0 0 0 000 Figure 18 .00* 30 a Ob 0 0 Figure 19 Figure 20 t_ I i r -4- 4 Figure 1 shows a cable sleeve consisting of a sleeve cylinder MR and two laterally arranged sealing bodies DK. The sealing bodies DK consist, in a known way, of plastic and have, not shown here, a lamellar structure for example on the inside, which means there are lamellas arranged one behind the other in the entry direction, between which in each case intermediate spaces are located as is known from the mentioned state of the art.

This structure is then particularly important if additional cable entries are provided which are matched to the respective diameter and produced by making a circular cut-out. In Figure 1, for the sake of clarity, this type of entry known per se is not shown. Thus, the possibilities are indicated here which are particularly suitable in Ono 15 a design with formed-on entry fittings ES, according to the invention, on the sealing body DK. Thus, each sealing o 0 on body DK has here one or two entry fittings ES which in o this case are directed outwards. In theory, the entry o "ofittings can also be directed into the sleeve. These a2 o 0 entry fittings ES have an inner diameter which is larger than the introduced cable K. The invention envisages inter alia that the seal between the end of the cable entry fitting ES and the introduced cables K is made with aO o a diameter-compensating seal element. For this purpose, a oa"*25 in this case heat-shrinkable elements are used which can no a be constructed according to requirements. DiameteroC a compensating seal elements consisting of elastic material can also be used and would be for example advantageous as temporary seals when perforraing repairs. When sealing uncut cables a heat-shrinkable hose SS can be pushed on for example even before the introduction of the cable K.

When introducing uncut or already introduced cables K, in each case a heat-shrinkable collar SM is used which is laid around and then sealed with a longitudinal seal V.

Furthermore, the possibility is indicated that the plurality of cables K can be led out of or into an entry fitting ES. Sealing then also occurs with the aid of a heat-shrinkable hose SS or a heat-shrinkable collar SM, an additional sealing element in the form of a i- c~i II- distributor element VE, for example in the form of a clip, being arranged between the cables. After the heatshrinkable sealing elements have been arranged, they can be shrunk tightly onto one another, in general these seal elements being provided with an inner coating consisting of a thermoplastic adhesive, by means of which the sealing effect is increased. As can be easily recognized, each entry hole is treated independently of the other entry holes, which is particularly advantageous on making subsequent changes. However, problems are encountered due to the fact that when treating individual entry holes the other seals are supposed to remain undamaged. This is then only particularly easy if a longitudinal incision or a longitudinal division is made in the relevant entry 15 hole in each case. In the diagrammatical representation 0,0; of Figure 1 shown here, for the sake of simplification and illustration, incisions are made in all the antry S4 holes. The special properties of the invention having partially divided sealing bodies with suitable angular cut-outs are explained in greater detail below. Since sealing according to the invention occurs with the aid of a diameter-compensating seal element, in particular with heat-shrinkable elements, in contrast to previous soluoo tions the cable clamping devices can be made simpler and 25 even be completely dispensed with with corresponding aa dimensioning. The material and the strength of the heatshrinkable sealing elements SS or SM can be selected in such a way that the mechanical strength is sufficient to take up or to span mechanical loads occurring on the cables. By using solid sealing means, such as for example slip-free thermoplastic adhesives, which are solid at normal operating temperatures, no more longitudinal movements can occur in the sealing area as is the case with plastic sealing means. These movements have up to now required additional securing measures for the cables.

This can at least to a large extent be dispensed with since a rigid connection exists between the cable and the entry fitting via the rigid, shrunk-on seal element.

Figures 2 and 3 show the division of a sealing i

Jh C C 6 body DK into two sealing body sector cut-outs DKSI and DKS2, the two cutting planes through the entry fitting ES and the sealing body DK being positioned in relation to one another at such an angle that the cable to be introduced into the entry hole ESO can be introduced after removing the outer sealing body sector cut-out DKS2 in the remaining sealing body sector cut-out DKS1. The cutting planes are preferably positioned in such a way that triangular cut-out parts are produced. A diameter matching is not necessary here since this matching is carried out with the aid of the heat-shrinkable hose, to be put on at the end, or of the heat-shrinkable collar by means of heat shrinking. It can be recognized here that, for example, the sealing body sector cut-out DKS1 according to Figure 2 encloses a larger angular range than the 0' a a sealing body sector cut-out DKS2, which fits it, accoro ding to Figure 3. Moreover, the sealing areas of the o longitudinal seal LD consisting for example of groovero spring systems, in the entry fitting part ESl and the ring seal of the actual sealing body DK are to be provided with seal lips DL, the actual design being of less importance for the overall design of the invention.

Furthermore, it is indicated here that the seal zones DZ in the sealing body extension DKA1 can have a lamellar 0 25 structure, as is already known per se. Thus, with such a design additional cable entries can be produced by 4 appropriate cutting out. As will be shown later, the 0404 cable entry fittings ES do not have to be arranged centrally in the sealing body so that many different 30 kindA of variants are available. In addition, in the sealing zones DZ other mechanical guiding or bracing devices can be provided which on being placed together ensure mutual guiding and holding. The cross-sectional shape of the entry fitting ES is also not compulsorily predetermined. For e -ample, oval designs are also con-

I,

ceivable particularly with branching entries since then a plurality of, cables can be led next to one another into one entry hole. Sealing of a branch occurs in the way already described in Figure 1.

'R I, 7 1 -rI.

-7- Figure 4 shows a possible way of securing the two sealing body sector cut-outs DKSl diid DKS2, which have been placed together, with the aid of retaining straps SB, one of these retaining straps SB being arranged on the sealing body extensions DKAl and DKA2 and another being arranged approximately at the end of the entry fitting ESI and ES2. Basically, the heat-shrinkable object pulled on later is sufficient here for securing.

The representation is simplified and does not indicate into what sizes of angle the units entry fitting sealing bodies are divided. It is possible to divide the latter into two equal halves, into unequal angles, in the centre and also outside the centre in the entry area of the sealing body. This applies for all embodiments. In a 00 0 15 preferred manner the entry fittings are arranged outside o00 the centre since smaller partial cut-outs are then 0 o 0o.°produced and also since in the inner region additional 0 entry holes can be better arranged by cutting out.

o .o Figure 5 shows securing of the two sealing body o 00 0 0 o 20 sector cut-outs DKS1 and DKS2 with the aid of a joint G, which is arranged at the outer ends of the entry fitting parts ESI and ES2 in such a way that the two parts which have been brought together in an articulated manner can o be tilted until they touch one another along the sealing 0° :25 plane. This tilting movement is represented by the arrow.

The joint G is expediently formed in such a way that it 0 00 o. permits the two parts to separate from one another. In the longitudinal sealing plane DE, as in all other exemplary embodiments sealing inserts of any kind can be "30 arranged.

-a Figure 6 shows a further example of securing of the two sealing body sector cut-outs DKS1 and DKS2 with the aid of locking elements RE which, on the two parts being pressed perpendicularly against one another, bring about a mutual bracing.

Figure 7 shows the mutual connection of sealing body sector cut-outs DKS1 and DKS2 with a slide mechanism. In the sealing planes DE sliding guides SF are arranged, by means of which both parts are secured in one i I i i II LIL---L-^I 8 another at the same time.

In Figure 8 the design of the sealing planes DE between the entry fittings DS is illustrated, the wall of the entry fitting Es being of such a thickness here that the guiding and also seal elements can take the form of a spring and a groove within the width of the wall.

Figure 9 on the other hand shows an exemplary embodiment for relatively thin-walled entry fittings ES, in which in the region of the sealing planes DE an extension of the wall is then formed on one side orp as sho,.-n here, on two sides so that the construction of the sealing elements becomes also possible here. In the preferred one-sided inward extension of the entry fitting a surface which is smooth towards the outside is then o 15 produced so that no transition elevation is formed here.

a o ooo As sealing inserts both elastic and plastic materials 0: known perse can be considered, even a combination of the two materials being possible. A sealing system which is .es constructed with a groove on each side is also possible 0 so that a closed sealing groove is produced, into which a packing cord can be laid. Here, in addition a lateral guide is then to be provided to prevent lateral displacement.

00*0 0 0 0000 00 0 o 00 *000 Figure 10 shows in a sketch how the longitudinal 25 securing of the entry fitting parts ESI and ES2 can also be provided with lateral flanges or shoulders. One longitudinal side here is provided with a joint-like guide groove GN whilst the opposite side is provided with a thickened guide spring GF. In this way, the entry fitting part S2 to be inserted can be brought into position in a guided manner. The second longitudinal side is provided with flanges, into which screw elements SE are inserted for final securing.

Figure 11 shows a similar design to that of Figure 10, the same construction with flanges being selected here on the two longitudinal sides.

Figure 12 illustrates once more in a simple manner the assembled combination consisting of the two longitudinal parts ESl and ES2 of the entry fitting ES .I i _i -9which is formed via a shoulder slope AS onto the actual sealing body DK of the cable sleeve. Here too it must be added that the division of the longitudinal direction can occur at any desired dividing angles appropriate for the circumstances. Referred to the centre point of an entry fitting ES for the sealing body sector cut-outs which can be pulled off outwards, angular ranges from 100 to 1800, preferably from 900 to 1800, are suitable for universal application.

Figures 13 and 17 serve to explain the construction of the entry fittings ES, a simple diagrammatic representation being selected.

Figure 13 illustrates a cylindrical entry fitting ESZ on the sealing body DK, in which in addition on the o 0 15 outer end of the entry fitting a terminating wall SAA was arranged whilst in the exemplary embodiment according to Oo Figure 14 such a terminating wall SAI is used on the oo 0 inner end of the entry fitting ESZ. Such a terminating 00 0 .o wall is then useful if initially no cable entry is made 0 *0 0 o o"20 through this entry fitting. In this way, the sealing body DK can be tightly sealed off from the outset without particular measures. When required, this terminating wall SAA or SAI can be removed. However, such a terminating 0 wall could also be made by means of an elastic or even a o0 25 heat-shrunk cap which is placed over the outer end of the entry fitting and can be removed when required.

0o0 0 Figure 15 shows an exemplary embodiment in which an approximate diameter preselection can be made so that the diameter differences between the hole and the cable to be introduced can be approximately matched to one another. For this purpose, stepped shoulders ESA are selected and the preselection is made by separating off at the appropriate step, Figure 16 shows a conical design of an entry fitting ESK so that, here too, an approximate initial matching of the entry diameter can occur.

In Figure 17 the conical embodiment is supplemented with stepped shoulders ESA so that, here too, an approximate matching can occur. Otherwise the cylindrical

A

10 and conical embodiments are identical.

Figure 18 shows how, with a further embodiment according to the invention, either large diameter differences are distributed over the entire circumference or support can be provided for diameter-compensating seal elements such as heat-shrinkable articles only in certain areas requiring support such as for example beneath a longitudinal seal consisting of heat-shrinkable collars SM. Thus, one or more tongue-like formed-on pieces can be attached as diameter-compensating elements with a supporting effect DA to the end of an entry fitting ESl and/or ES2, which formed-on pieces can then be bent over inwards along an annular bending line until they rest on the cable K. These diameter-compensating elements DA are, when required, also held together with a retaining o 0 element DAE so that the resulting conical shape is o0 SoOOo secured as the figure shows. By the representation with dots and dashes it is indicated that a plurality of such diameter-compensating elements DA can be arranged. They °20 serve with the heat-shrinkable collars SM, particularly in the under region of the longitudinal seal as a counter-brace, it then being sufficient depending on circumstances if only one entry fitting part ES2 has such a o 0 tongue-like extension. The diameter-compensating element oo 0,25 DA can also be shortened along its length depending on the heat-shrinkable object used. The retaining element .o0 DAE can also be used additionally as a securing element and also as a centering element for the introduced cable K so that in this way the cable K is at the same time 130 mounted centrally in the entry fitting ES. Independently fit of this, separate annular centering pieces with matched diameters can also be arranged inside the entry fitting ES for the purpose of centering the cables K.

Figure 19 shows a separate support element SE which can be used for supporting the diameter-compensating seal elements, for example the heat-shrinkable collar. This support element SE has a rectangular part on which tongues Z are formed which come to a point via a bending line KL. During installation, the support element i 1 __aA p.-

~I

i 11 SE with its rectangular part is shaped round the entry fitting and secured.

The flexible tongues Z are bent over, for the purpose of diameter-compensation, along the bending line KL as far as the cable which is to be introduced and are then fixed in position at least with the aid of a heatshrinkable object. In this way, one more or less closed support arrangement is produced depending on the diameter-compensation.

In Figure 20 all the possible entries on the end face of a sealing body DK are represented in an overview.

Thus, this sealing body DK is divided in two along the dividing line THL. Along this dividing plane, cable entries EO can be cut in according to the previously

PO

0ooo 15 known method depending on requirement and to the ap- 0. propriate size. Furthermore, it is indicated that an oo 0 .0o uncut entry fitting ESU is permanently formed on for oo example in the upper sealing body part DKSl. Expediently, 0e o 0 0.0 this entry fitting ESU has a terminating wall according 0 0 o 20 to the described type and can thus be opened when required. The possible cable entries have been discussed in detail. In addition, in the lower sealing body part DKS2 a cut entry fitting ESl-ES2 is arranged and to be precise *000 the approximately triangular sealing body sector cut-out DKS3 can here be removed outwards so that in this way even uncut cables can be introduced and to be precise then independently from the other seals so that the latter remain unaffected. Then, in the dividing planes TLS the longitudinal sealing occurs in the described 30 manner. Furthenrmore, it can be recognised that the entire sealing body DK with its circumferential lip seal DL is clamped tightly inside the sleeve tube MR which has a wedge-shaped longitudinal seal with wedge elevations KW and a locking bar KS.

The function of forming a seal to the cable can be improved when required in the heat-shrinkable area of the seal element by an additional annular plastic sealing insert.

The sealing body consists of plastic and can also L, .i 12 be provided with flame pro 2ction. The entry fittings can be formed onto the sealing body or be inserted tightly as a tube into a cut-out entry hole. In such a case, the tube can even consist of metal.

To sum up, the following advantages over the state of the art can be identified: Thanks to the multiplicity of possible entry holes, practically all conventional cases can be covered and indeed using both cut and uncut cables.

A mechanical cable clamping device which was customary until now can be to a large extent dispensed with due to the rigid seal at the ends of the entry fittings so that no further additional elements are required.

Thanks to the various division variants, possible 0o0,, ways are obtained of reopening and closing individual cable entries without damaging the seals 0°I which are not affected by this.

The seals are simple and thus not prone to faults.

',20 The installation technology is simple and can be carried out with commercially available tools.

Subsequent introduction of cables is possible without opening the sealing body.
