Cable sleeve

The invention relates to a cable sleeve for connecting inserted Individual lengths of cables, consisting of two plastic half-shells with connecting flanges resting against each other on both sides.

Cable sleeves are known which are designed as cast sleeves. Such cast sleeves often do not seal properly because the © flat connecting flanges do not fit tightly against each other. In addition, there are signs of corrosion that open

make such cast sleeves considerably more difficult and at least with strong Corrosion do not allow their reuse. Finally, the high weight of cast sleeves is a disadvantage. To avoid this Disadvantages have therefore been developed from plastic cable sleeves, e.g. B. made of polyester, however, in terms of their sealing effect also not yet satisfactory. In fact, the previously known cable sleeves made of plastic half-shells need regularly additional inner shells as a vapor barrier, although the connecting flanges have grooves in which a sealing cord inserted and permanently plastic sealing compound is used. The invention aims to avoid these disadvantages.

The invention is based on the object of creating a generic cable sleeve made of two plastic half-shells which is characterized by a perfect sealing effect and can do without additional inner shells as vapor barriers.

The invention solves this problem with a generic one Cable sleeve characterized in that the one connecting flange of one plastic half-shell has at least two extending in the longitudinal direction of the sleeve Tongues with a groove arranged in between and, accordingly, the associated connecting flange of the other plastic half-shell has at least two grooves extending in the longitudinal direction of the sleeve with a tongue arranged between them, and that these Tongue / groove arrangement is reversed in the two other mutually associated connecting flanges and when closed Plastic shells all the tongues and grooves interlock. - These measures of the invention have the consequence that

despite the implementation of two tongues and one groove on the one hand and two grooves and one tongue on the other hand the four connecting flanges of the two plastic half-shells these plastic half-shells remain interchangeable. Esp. however, it becomes a meander-shaped tongue and groove connection produced between the connecting flanges, from which a multiple seal results, so that perfect Sealing effect is guaranteed. In combination with the claimed measures, but also independent of them, is special Meaning that the springs have a polygonal cross-section and the grooves have a channel cross-section and thus a sealing means located between the connecting flanges, See e.g. sealing compound or sealing tape, non-sagging or non-slip pinch between them. Depending on the meander-shaped or wave-shaped design of the tongue and groove cross-section ^ the sealant cross-sections are thus also formed in a meandering or undulating manner. This is already an increased Barrier effect against the ingress of gaseous or liquid Media reached. This locking effect is reinforced by the fact that the springs are designed as a polygonal cross-section, in The sealant is therefore subject to increased specific surface pressures in the area of its edges. So that the sealant is properly received by the tongue and groove connection, it is provided that the springs with the respective intermediate Groove external overflow channels are assigned and the rest the groove cross-section is selected to be larger than the tongue cross-section. These measures of the invention have the consequence that the connecting flanges in spite of the interposition of the sealant, they are always in perfect contact with one another.

Further features essential to the invention are listed below. The invention provides that the connecting flanges

have sack recesses running transversely to the longitudinal direction of the socket, which form break-open openings when the connecting flanges lie against one another. Is z. B. the cable sleeve according to the invention realized as a mere adhesive socket, then the adhesive connection can be made by simply inserting a screwdriver into the Bag recesses and then turning the screwdriver are broken open as it were.

The invention teaches that the plastic half-shells can be broken out j Sealing plugs to create compression openings for the

The special advantage of the TSG plastic half-shells lies in the high rigidity - based on weight and material consumption - which is due to the specific density- ' distribution is effected. The extensive freedom from orientation and tension as well as the low tendency to warp are guaranteed the result is a flawless cable sleeve with exactly abutting one another Connecting flanges.

The advantages achieved by the invention are substantial it can be seen that a cable sleeve made of plastic half-shells is realized, which is characterized by optimal sealing effect in the area Their connecting flanges are characterized by dispensing with the otherwise necessary inner shells as vapor barriers. The cable sleeve according to the invention can also be used as a casting sleeve. It is in the embodiment as Screwed sleeve is just as conceivable as an adhesive sleeve. If you want to be able to open the coupling sleeve again, it is recommended the use of a silicone adhesive that is surprisingly easy to peel off and reapply. It is recommended to use it of plastic cable clamps during the time that the silicone adhesive needs to build up the adhesive effect. Always the sealing means is pressed or clamped in the groove / tongue arrangement on both sides of the connecting flanges in such a way that Leaks are excluded.
