Designation: "Cable sleeve"

909845/00

The invention relates to a cable sleeve with an insert which envelops the splice, over which and which open out Cable ends a shrink tube is shrinkable.

In known cable sleeves of this type, this insert consists of two essentially rigid aluminum shell halves with toothed and tapered ends to adapt to the cable ends (Brochure from Raychem XAGA 800). However, these rigid shell halves are only for cable sleeves or splices of certain sizes can be used, so that a large number of molded shell inserts of this type must be manufactured and kept in stock.

It has therefore already been proposed that the splice wrapping insert made of dry crepe paper rolls to be wound (prospectus from Raychem XSMG). It has been found to be disadvantageous that the Crepe paper absorbs humidity during processing, which improves the quality of the insulation in the splice area is decreased. Furthermore, deposits formed in this way have to be removed when reopening becomes necessary of the splice proved very difficult in that the one on the inside of the shrunk-on tube located adhesive enters into an intimate connection with the crepe paper, so that when the insert is cut open Pieces of crepe paper on hands and tools are almost indispensable.

tend to stick in a tangled way. In addition, cable sleeves with such inserts tend to shrink over the Shrink tubing too bulky sagging, which is perceived as annoying in many cases. Also is through the soft crepe paper insert only provides a low level of mechanical protection for the splice against impact loads and the like and, finally, the splice area is also applied when the shrink tubing is shrunk on transfer a lot of heat, which is also disadvantageous for the insulation materials in the splice area.

The object of the invention is to provide a solution ₃ which in usability for arbitrarily large splices good insulation against humidity, mechanical stress and heat transfer ensured _s and allows a schnelüaiund clean access to the splice when reopening of the sleeve, and also a dimensionally stable uniform exterior of the sleeve according to the ensures that the shrink tubing is covered.

In a cable joint of the above kind referred to this object of the invention is achieved, according to _s that the insert of a to _s extending over the entire length of the sleeve around the splice ^ ickelbaren roll of stiff., Feuchtigkeitsisoliertem material is formed _s with the side edges for adjustment are formed slotted at the cable ends opening.

909845/0001

Because of this training, it is dimensioned accordingly for a long time Roll an effortless adaptation to any size splice possible and also to a different one Number of leading cable ends. Furthermore, when the cable sleeve is reopened, it is cut open the shrink tube a quick and clean access for splicing possible by simply unwinding the insert in one piece. Furthermore, the Use of the stiff, moisture-insulated material ensures that there is no air humidity during processing can get into the socket. In addition, the stiff material results in a good mechanical and Thermal insulation protection and the cable sleeve is given an overall uniform, generally cylindrical configuration.

To make it easier to adapt to the cable ends, it is advisable to make the slots conical on the side edges, so that there is sufficient play for the adjustment of the toothed edges that remain is present at one or more leading cable ends.

The insert can expediently be formed from moisture-insulated rigid cardboard. You can also do this place an aluminum foil inside the box, creating a further improved effect of the insert results, in particular also as a water vapor barrier.

Furthermore, you can use the insert to increase the longitudinal stability provided with longitudinal folds or longitudinal corrugations. At the same time, these longitudinal folds or Longitudinal corrugations then also improve the rollability even if the insert is entirely off consists of relatively stiff material.

Finally, the insert can also be radial at the inner end of the slots in the side edges Pal tongues provide j in such a way that there is a clear orientation for the beginning of the tapered socket ends results.

The invention is explained in more detail below with reference to the drawing, for example. This shows in

Pig. I a perspective view of an insert according to the invention in the partially rolled-up state, and in

Fig. 2 Detail A of Fig. 1 in an enlarged view.

In the illustration according to FIG. 1, an insert made of moisture-insulated cardboard, denoted overall by 1, is shown in the state partially already wrapped around a cable splice, a cable 2 opening into this cable splice at one end and two cables 3 and M at the other end.

The panel 1 is composed as shown in Detail A (Fig. 2) is visible ₃ consists of two insulated moisture cardboard layers 5 and 6 with an interposed aluminum foil 7 ·

The two longitudinal edges of the insert 1 are formed with outwardly widening slots 8, wherein Radial tongues 9 are provided at the inner end of the slots in the side edges. Furthermore, the insert is with Longitudinal folds 10 provided.

Because of this design it can be seen that the insert 1 is wrapped around a finished splice and the edges can taper well adapt to the cable ends 2 to 4, regardless of how many cable ends each end at one end of the sleeve.

Of course, the exemplary embodiment described can be modified in many ways without the basic idea to leave the invention. For example, the / longitudinal edges could be simple, i.e. not facing outwards widening slots be provided. Instead of the longitudinal folds, the entire insert could be designed to be corrugated and an aluminum foil as an intermediate layer could possibly be dispensed with and the like.
