Abstract

A bundle of tubes or microtubes, in particular optical cable guards and liquid media guides, is formed by individual tubes or microtubes and a connecting sleeve. The bundle (2) of the bundle (1) is formed by the jacket (4) of the individual tubes or the microtubes (3), wherein the sheaths (4) are joined together by connecting lugs (5). The connecting lugs (5) are preferably connected tangentially to the jacket tube (4) of the individual tubes or microtubes (3) so that the bundle is oriented in the original shape in one plane. Furthermore, the connecting lugs (5) are preferably flexible and each of the individual tubes or microtubes (3) is slidable in its housing (4) of the bundle (2) of the bundle (1).

Description

Bundle of tubes or micro tubes

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a bundle of tubes or micro tubes, and more particularly to fiber optic cable protectors and fluid media conduits.

BACKGROUND OF THE INVENTION

With respect to bundles of tubes or micro tubes for protecting optical cables or fluid media lines, embodiments are currently known in which bundles are formed by joining tubes or micro tubes by means of bridges that are rigidly connected directly to each tube or micro tube. The main disadvantage of these solutions is that the circumferences of the individual pipes are never perfectly smooth at the point of eventual removal of the bridges - the remnants of the bridges remain. This then causes problems, for example, when joining pipes with waterproof couplings and the like. In this embodiment, the bridges (due to manufacturing reasons) also have a relatively high thickness, which results in higher rigidity, respectively. less flexibility of the microtube bundle around the longitudinal axis and the associated more difficult handling.

For these reasons, it seems more advantageous from the application point of view to connect the smooth tubes to the bundle with a common envelope. In this respect, for example, a multiple bundle of seven microtubes arranged around a central cable connected by an outer halo of a rounded corner shape is known - U.S. Patent Application Publication No. 2005224124.

Furthermore, a bundle of a plurality (19) of micro tubes together in a hexagonal outer shell with rounded corners is known - United Kingdom Patent No. 2408393.

These bundles are more convenient for handling than directly bonded microtube bridges. On the other hand, the problem is that the outer casing connects a relatively large number of microtubes and if one or more of them are released - for example, to branch out from the central direction (so-called branching), the bundle completely disintegrates and complicates subsequent handling .

From this point of view, the solution according to European Patent No. 0939262 is somewhat more advantageous, in which the microtubes are connected two by two in the outer sheaths, wherein the outer sheaths of the pair of tubes are then joined into a bundle by bridges situated along the transverse axis of the tube profiles. However, even this solution does not reliably ensure trouble-free branching of individual • • ♦ • ··

* tubes. In addition, the compact coupling of the tubes in pairs increases the rigidity of the bundle and complicates the work if it is necessary to adapt its overall profile to a certain external shape.

SUMMARY OF THE INVENTION

To a large extent, the bundle of tubes or micro-tubes according to the invention, formed (like the above-mentioned bundles), consists of individual tubes or micro-tubes and a connection sleeve, to a large extent contribute to the elimination of the above-mentioned drawbacks.

The invention is based on the fact that the bundle of the bundle is formed by sheaths of individual tubes or microtubes, the sheaths being joined together by connecting bridges.

From the point of view of shape, these connecting bridges are preferably connected tangentially to the sheaths of individual tubes or microtubes - so that the bundle is oriented in one plane in its original shape.

Furthermore, it is advantageous if the connecting webs are flexible and each of the individual tubes or micro tubes is slidably mounted in its bundle of the bundle.

The main benefit of the bundle according to the invention is its flexibility and the possibility of shape adaptation, which are associated with a smooth possibility of branching even with individual tubes while fully maintaining the compactness of the bundle as a whole.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS The drawings in which the bundle of microtubes in the exemplary embodiment is shown in cross-section are explained in more detail.

Example of practical implementation

The bundle of microtubes - fiber optic cable protectors in the exemplary embodiment (see Fig.) Consists of five individual microtubes and a connection sleeve. The connecting sleeve 2 of the bundle 1 is formed by sheaths 4 of individual micro-tubes 3, these sheaths 4 being joined together by connecting bridges 5.

The connecting bridges 5 are connected tangentially to the sheaths 4 of the individual micro-tubes 3 so that the bundle is oriented in one plane in its original shape; the connecting bridges 5 are flexible.

Each of the individual micro tubes 3 is slidably mounted in its jacket 4 of the bundle 2.
