The invention will be explained in more detail below with reference to FIGS. Show it

1 a schematic sectional view of a cable composite strand with a single-wound connecting device; and

2 a schematic sectional view of a cable composite strand with a multi-wound connecting device.

The 1 and 2 show a schematic sectional view of a Cable composite strand 110 with a connection device 100 , wherein the cable composite strand 110 in the illustrated embodiment, several strand-like elements 120 includes. As string-like elements 120 In particular, cables, hoses, pipes or the like come into question. These elements 120 are by means of a connecting element 130 connected in the circumferential direction, being used as a connecting element 130 a cable tie is used. Alternatively, as connecting elements 130 also another connecting element 130 such as clamps, twine, hose binders, rope ties or the like may be used, wherein the use of a cable tie the connecting device 100 for producing a cable composite strand 110 simple, inexpensive and flexible to use.

Between the elements 120 and the connecting element 130 is a sleeve-like structure 140 arranged, the structure 140 a central first area 142 that of a second area 144 and a third area 146 is surrounded. Both the first area 142 , as well as the second area 144 and the third area 146 can each form windings, wherein the strand-like elements 120 from the windings in the 1 illustrated embodiment are simply wrapped.

In the figures it is clearly shown that the first area 142 such at its edge regions through the second region 144 and the third area 146 it is limited that the first area 142 a kind of circumferential groove for receiving the connecting element 130 formed.

Both the second area 144 as well as the third area 146 be directly on the string-like elements by means of the self-adhesive bottom during assembly 120 fixed. Further, in this way and by the overlap of the second area 142 and the third areas 146 at the edge areas of the first area 142 also the first area 142 fixed to the elements, so that an axial or radial displacement of the entire sleeve-like structure 140 not possible.

Also the first area 142 can be designed as a winding. Whereby this winding of the first area 142 the strand-like elements 120 in the circumferential direction at least simple, alternatively wrapped several times. It must be independent of the number of windings of the first area 142 always make sure that the second area 144 and the third area 146 the first area 142 limit such that an axial displacement of the connecting element 130 can be prevented.

In an alternative embodiment, the first region 142 be designed as a sleeve. A sleeve has the advantage that it has a smooth surface structure without bumps, regardless of their background, whereby a very good rotatable in the circumferential direction, connection between the connecting element 130 and the string-like elements 120 can be guaranteed. The second area overlapped 144 and the third area 146 the sleeve at the edge areas, whereby the sleeve and thus the first area 142 on the one hand limited on both sides and on the other to the elements 120 is fixed. And also the first area 142 may have a self-adhesive bottom. This has the advantage that the first area is independent of the second area 144 and the third area 146 on the elements 120 is fixed, whereby the attachment of the sleeve-like structure 140 on the string-like elements 120 more durable and stable.

In the in 2 illustrated possible embodiment wrap the windings of the first area 142 , the second area 144 and the third area 146 the string-like elements 120 triple, whereby in principle the number of windings is variable and can be adapted to the respective situation. For example, the first area 142 only have a single winding, whereas the windings of the second region 144 and the third area 146 are wound several times, creating the second area 144 and the third area 146 each would be much thicker than the first area 142 (not shown). That way, the first area could be 142 , the second area 144 and the third area 146 For example, have the same materials with a similar or even the same surface finish and yet would the first area 142 through the second area 144 and the third area 146 be bounded on both sides so that a circumferential groove would be formed, which prevents axial displacement of the connecting element.

In addition to the described and illustrated embodiments, further embodiments are conceivable which may include further modifications and combinations of features.
