DE3513620A1 - Electrical cable with a pattern - Google Patents

Abstract

In order to be able to provide an electrical cable having a transparent sheath and having at least two insulated wires with a large number of coloured essentially longitudinally running patterns, at least one wire insulating coating is covered by a second coating coloured as desired and sticks more strongly to the sheath than to the wire insulating coating so that it is also removed when the sheathing is stripped off the cable. <IMAGE>

Description

Patterned electric wire.

The invention relates to an electrical line after the master access of claim 1.

Such lines are e.g. in the form of flat cables through the DE-AS 20 53 628 became known.

The invention is based on the object of an electrical line with a transparent coat, the appearance of which comes in a variety of two- or multi-colored patterns can be designed, but after stripping the original insulating layer of each wire is exposed.

This object is achieved by the invention according to claim 1. Advantageous refinements of the invention are characterized in the subclaims and the following example description can be found.

The invention enables the line to have any stripe pattern to be provided, which preferably run helically or in the manner of an S-Z stranding. While the core insulation layer after stripping e.g. the standardized color - e.g. blue, brown and green-yellow - and can be connected in accordance with standards, can the external appearance of the cable suit the taste or

can be adapted to the wishes of the user or customer.

The invention can be used particularly advantageously in the case of device feed lines or device connection lines, especially in the case of heat-resistant lines of these Kind of with an outer jacket made of braided or braided glass fibers or glass yarns were provided. Such lines are due to the relatively slow Spinning or lace-making technology is labor-intensive to produce. Using new heat-resistant and thermoplastically processable and cross-linkable plastics these conventional lines are becoming less and less important.

The conventional fiberglass-braided cables, e.g. for irons, however, they are usually patterned, e.g. in black and white.

The new plastic-insulated cables tend to get dirty, especially if they are used in an appropriate environment. There are too Bracket connection lines have become known whose plastic sheath with longitudinal Stripes are provided so that, for example, a white-gray pattern results. It exists however, there is a need for further patterns, e.g. the or the Colors of the respective electrical device can be adapted. This need can are largely satisfied by a line according to the invention.

Beyond that aspect, the second layer is on the vein, though it is designed to be conductive, can be used as an auxiliary or monitoring conductor, e.g. -for lawn mowers, hedge trimmers or the like. The continue to serve proposed guiding passages. Both, second shifts and Beillauf, then not only have a decorative function, sonesern usa? I also have one Safety function.

In the drawing, two exemplary embodiments of the invention are shown.

In Figure 1, the color sequence is blue-heather violet, dreirna over distributed around the circumference, in the form of helical strips that run through the Stranding of the cores result.

After stripping the sheath, the core insulation layers are visible in accordance with the standard.

In Figure 2, the wire insulation layers are with a second layer in the colors black, red, gold (yellow).

Here, too, the stripping of the sheath turns the core insulation layer into the standard color exposed. The line shows helical stripes in the colors black, red, gold.

The stronger adhesion of the second layer to the jacket can be achieved by known Measures can be achieved, e.g. by applying a release agent (talc) between Core insulation layer and the second layer. In the simplest embodiment are all materials for core insulation, second layer and jacket made of a PVC that for heat-resistant applications, e.g. be crosslinked by means of electron irradiation can. In this case, all layers can be extruded, so that a uniform Manufacturing process is used.
