Definitions
- the sheath of an electrical or optical communication cable is intended to protect the cable core consisting of the stranding elements (optical fiber cores, copper cores, dummy elements), the support and tension elements as well as the existing winding, if any, from mechanical, thermal and chemical influences and from moisture.
- the sheath usually consists of soot-blackened polyethylene (with or without a barrier layer), since this easy-to-process plastic has almost constant dielectric properties over a wide temperature range and it withstands all the mechanical and chemical loads that usually occur.
- the marking of the cable jacket with numbers, letters, characters etc. can be done during the jacket extrusion, for example using a marking wheel. With the help of the marking wheel, a white plastic powder with a distribution corresponding to the desired marking is applied to the still hot, soot-blackened plastic jacket and fused with it by the residual heat still present.
- Plastics can be marked much faster and more flexibly by irradiation with a laser probe (see for example [l] - [2]). Depending on the laser power, the outer plastic layer is locally melted, foamed or evaporated and its surface or structure changed accordingly.
- a change in color occurs in the irradiated area when a pigment added to the plastic is used with the help of a 2 selectively destroys or burns an absorption maximum of the pigment-matched laser probe (see, for example, [3] and [4]).
- the invention relates to a sheath which can be marked, in particular laser-marked, by irradiation with photons, for example for elongated or strand-shaped objects (cable cores of all types, in particular cores of power cables or electrical or optical communication cables).
- the casing should be such that a clearly recognizable, abrasion-resistant marking can be produced without contact on its surface.
- Sheaths with the features specified in patent claims 1 and 11 have this property. Advantageous further developments and refinements of the casings are the subject of the dependent claims.
- cable sheaths with a high soot content of up to 2.5 ⁇ 0.5% by weight have hitherto been provided with a white, but less abrasion-resistant marking using a marking wheel.
- the principle of laser marking which can also be used in principle, results in material removal and thus damage to the cable sheath.
- the engraving generated is difficult to recognize due to the lack of contrast.
- the disadvantages described can be avoided by using the casing according to the invention as a soul shell. Since the comparatively thin outer layer of the sheathing, which has a lower proportion of soot, completely absorbs the incident laser radiation, the inner layer underneath, which takes on the protective function, remains intact. The abrasion-resistant marking created in the outer layer appears as a white structure against a black background.
- FIG. 1 shows a communication cable for outdoor use and FIG. 2 shows the laser-markable sheath of the outer cable
- the core of the communication cable 1 shown in cross section in FIG. 1 consists of the steel or glass fiber reinforced plastic central element 2 (kink protection and / or strain relief), the stranding elements 3/4/5 arranged concentrically in a position around the central element 2 and the winding 6.
- a mass filling the gusset of the soul (petrolatum) ensures that penetrating water does not spread in the longitudinal direction of the cable 1.
- the cable core has a so-called copper quad 3, a blind element 4 made of polyethylene (PE), for example, and three loose tubes 5 as stranding elements.
- Each of the loose tubes 5 consists of a plastic sheath and a plurality of optical waveguide fibers 7 arranged therein and fixed by a thixtropic gel.
- Aramid yarns 8 are used in particular as tension-absorbing / tension-relieving elements. They are arranged between the soul winding 6 and the black cable jacket 9.
- the sheath 9 of the communication cable 1 is constructed in layers.
- a carbon blackened polyethylene in particular a polyethylene copolymer (polyethylene-ethylene-vinyl acetate), the carbon black content of which is, for example, 1-3% by weight, in particular 2.5 + 0 , 5% by weight.
- preferred 4 wise 0.05-0.2 mm, in particular 0.1 mm thick outer layer 11 are polyethylene or polypropylene (PP) m adhering well to the polyethylene inner layer 10.
- Carbon black as a dye is also added to the outer cladding layer 11 serving as the marking area, the carbon black content being in the range from 0.2 to 0.8% by weight, in particular 0.2 to 0.5% by weight, preferably in the range from 0.3 - 0.4% by weight.
- Both black-colored jacket layers 10/11 are applied to the cable core by coextrusion and welded together. If the layers 10/11 serving as cable sheath 9 consist of different materials, an adhesion promoter or a melt or reaction adhesive ensures their firm connection.
- a computer-controlled deflection unit and imaging optics are assigned (see for example [1/2]).
- the deflection unit can in particular consist of two to be orthogonal
- Axes rotatable mirrors and corresponding control electronics exist.
- the content of soot and the thickness of the outer cladding layer 11 are selected so that they completely absorb the incident laser radiation. The laser radiation therefore does not reach the cladding layer 10 on the soul side, so that its mechanical stability and tightness are retained.
- the outer cladding material melts in the area of the laser focus. Since the carbon contained in the soot burns to C0 2 at the same time, a largely soot-free, foam-like structured area is created, 5 which scatters incident light very strongly.
- the area of the outer cladding layer 11 scanned with the laser probe thus appears as a white surface against a black background.
- - make the inside layer of the casing layered; - coat a cable sheath, a coaxial cable or a wire with a well-adhering material that contains the stated proportion of carbon black or graphite and then mark this material by irradiation with photons; - Provide the sheathing with tension-relieving and / or tension-absorbing elements (aramid yarns, steel wires, etc.);
- the inner layer of the suitably sized and sufficiently thick casing does not necessarily contain carbon black or graphite;
- HDPE high, medium or low density polyethylene
- MDPE low density polyethylene
- LDPE low density polyethylene
- polypropylene use another plastic which is transparent or at least translucent for radiation with a wavelength of 500 nm ⁇ ⁇ 1200 nm; 6
