Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The present invention is further explained below with reference to an exemplary embodiment and with the aid of the drawing, in which:

(2) FIG. 1 illustrates a cross-section through a conventional data transmission cable that comprises an inner separating element in the shape of a cross; and

(3) FIG. 2 illustrates a cross-section through a data transmission cable that comprises a central supporting element and a plurality of bundles of supporting element threads in accordance with the invention.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

(4) The data transmission cable illustrated in FIG. 1 is configured in accordance with ISO/IEC 11801-2002 and comprises a plurality of core pairs 101 having twisted, non-shielded cores. The core pairs 101 are fixed in position with respect to one another in a defined spacing via an inner synthetic material separating element 102 that is cross-shaped. The individual core pairs 101 are each arranged in a groove of the synthetic material separating element 102. The defined spacing between the core pairs 101 reduces in particular any cross-talk between the core pairs 101. All the core pairs 101 and the synthetic material separating element 102 are surrounded in a radial manner by an inner sheath 103 that is in turn encased by a braid shield 104. The braid shield 104 is in turn surrounded by an outer sheath 105 of the data transmission cable.

(5) The data transmission cable that is illustrated in FIG. 1 does in fact render it possible to strip a section of the outer sheath 105 and at the same time to strip a section of the braid shield 104 at intervals that are offset by approximately 5 mm. However, it is necessary to splice the synthetic material separating element 102 close to the line end using a separate tool after stripping a section of the outer sheath 105 and a section of the braid shield 104. It is therefore not possible to rapidly customize the conventional data transmission cable illustrated in FIG. 1. In other words, it is difficult to customize the cable at the respective place of use and at the same time it is not very practical with respect to the adjustments required at the respective place of use when guiding through an already pre-customized cable.

(6) For the above reasons, a synthetic material separating element is not provided in the case of the data transmission cable that is illustrated in FIG. 2. This data transmission cable in the present exemplary embodiment is configured as a cat-6A cable in accordance with ISO/IEC 11801 and comprises 4 core pairs 201 that each comprise a pair of cores that are twisted with one another. Furthermore, a central supporting element 202 is provided that is surrounded by the core pairs 201 and lies against the core pairs, and the central supporting element 202 orients the core pairs 201 with respect to one another. The central supporting element 202 acts as a position fixing element together with the total 4 bundles 203 of supporting element threads that are arranged offset with respect to one another in the peripheral direction in each case by 90 around the core pairs 201. The central supporting element 202 and the supporting element threads may be configured, for example, from polyvinyl chloride, polyethylene or aramid. Each bundle 203 of supporting element threads is arranged lying against two respective core pairs 201 that are adjacent to one another. Consequently, the core pairs 201 are fixed with respect to one another, on the one hand, by the central supporting element 202 and, on the other hand, by the bundles 203 of supporting threads. In this manner, it thus is possible to forego a synthetic material separating element between the core pairs 201.

(7) An inner sheath 204 that is configured from an insulating material and encases the core pairs 201 and the bundles 203 of supporting element threads acts as an additional fixing element for the core pairs 201. The inner sheath 204 is surrounded by a braid shield 205 that is configured, for example, from copper or aluminum and in turn is surrounded by an insulating foil. The foiled braid shield 205 is finally encased by an outer sheath 206 of the data transmission cable. The outer sheath is preferably configured from a polyvinyl chloride, polyethylene or aramid.

(8) Fundamentally, the core pairs 201 may each comprise a separate shielding arrangement 208 that is formed, for example, by an aluminum foil, a metal braid, in particular a copper braid, or an aluminum-covered synthetic material foil. In addition, the core pairs 201 may each be embedded in an insulating filling mass 210 that is surrounded by the shielding arrangement 208 of the respective core pair.

(9) In order to strip a section of the data transmission cable that is illustrated in FIG. 2, it is possible, for example, to use the blade cassette, Siemens 6GK1901-1GB01 as a stripping or customizing tool. Initially, a length of line that is to be a stripped of insulation is measured at the stripping tool and the data transmission cable that has a corresponding length is placed in the stripping tool. The stripping tool is subsequently tensioned and rotated repeatedly about its longitudinal axis so as to strip a section of the data transmission cable. As a consequence, a cut is made in the peripheral direction into the outer sheath and the braid shield at positions that are predetermined by the stripping tool. By virtue of a pulling movement of the stripping tool in the longitudinal direction towards the cable end, parts of the outer sheath and braid shield that are to be separated are stripped from the remaining data transmission cable. Subsequently, the cores are revealed and fanned out, with the result that it is possible to cut off the central supporting element 202 and the bundles 203 of supporting element threads. Finally, the section of the data transmission cable that has been stripped is inserted with its cores for customization into the plug connector housing and the housing is locked.
