Magnetic anti-tangle sleeve for cables

Abstract

Magnetic sheath to prevent cable tangling, consisting of an elastic material with an integrated magnetized core, characterized by that the outer surface of the magnetized core carries the same magnetic pole over its entire length, so that several such shells repel each other.

Description

Technical field

[0001] The invention relates to a device for preventing cable tangling, particularly in the case of electrical charging, audio or data cables that are frequently stored or transported together. State of the art

[0002] Common solutions, such as cable ties, spiral sleeves or magnetic clips, only prevent several cables from collapsing uncontrollably, but do not create an active separation or repulsion.

[0003] Other systems require the complete threading of the cable or the use of fixed fasteners and are therefore cumbersome and inflexible to handle. Object of the invention

[0004] The aim is to provide a simple, flexible, and reusable device that prevents multiple cable sections from becoming entangled. The solution should be able to be retrofitted to existing cables as well as integrated into cables at the factory. Solution to the task

[0005] The problem is solved by a shell consisting of an elastic material with a magnetized core, wherein the outer surface of the magnetized core has the same magnetic pole over its entire length, so that several such shells repel each other.

[0006] The invention includes both sheaths that can be subsequently applied to a cable, as well as those that are permanently attached to the cable or are an integral part of the cable insulation.

[0007] Optionally, the casing can have a longitudinal structure that facilitates cable insertion. This can, for example, be designed as a... • open slot, • overlapping stretch zone, • elastic membrane, • Constraint or expansion joint or • an overlapping lip may be formed.

[0008] Additionally, the inner surface of the casing may have an adhesion-enhancing or microstructured coating, to increase the friction between the cable and the casing and to ensure a stable, but not permanent, connection. Advantages of the invention • Active prevention of cable tangling through magnetic repulsion. • Suitable for both retrofitted and permanently integrated cables. • Flexible, easy application without tools. • Optional adhesive inner surface for better grip. • Reusable, lightweight, electrically safe. • Suitable for mass production and cost-effective to manufacture. Example of implementation

[0009] A tubular element made of elastic silicone with an internal magnetized strip or magnetic particle core.

[0010] The outer surface has the same polarity along its entire length.

[0011] Optionally, the casing can have an overlapping, elastic longitudinal structure that opens when pressed and encloses the cable.

[0012] The inner surface can be coated with a tacky silicone coating that increases the coefficient of friction without leaving residue.

[0013] Several such sheaths repel each other due to their aligned magnetization, automatically keeping the cables apart.

Claims

Magnetic sheath for preventing cable tangling, consisting of an elastic material with an integrated magnetized core, characterized in that the outer surface of the magnetized core carries the same magnetic pole over its entire length, so that several such sheaths repel each other. Sheath according to claim 1, characterized in that it is firmly connected to a cable section or is an integral part of the cable insulation. Sheath according to claim 1, characterized in that it has a continuous longitudinal structure in the form of an open slit, an overlapping expansion zone, an elastic membrane, a predetermined breaking or expansion seam or an overlapping lip which facilitates the insertion of a cable section. Sheath according to one of the preceding claims, characterized in that the inner surface has an adhesion-enhancing or microstructured coating which increases the adhesion between the sheath and the cable and ensures a non-permanent, detachable connection.
