    The invention relates to a cable reel cable according to the preamble of claim 1.
    It is known that in order to save space, electrical cables to avoid tangling of the cable and / or for the purpose of easier handling, are wound up on cable reels. In devices in which the required cable length of such a cable drum cable for power supply and / or data transmission often varies, for example, input devices for a computer or household appliances, such as vacuum cleaners, often cable drums are used, which have a return device and the cable reel cable can wind themselves again. This can be done continuously, whereby the cable drum cable always has a certain voltage, or be controlled by a control. Since such devices usually have no devices that bring about an orderly winding of the cable in layers, these cable reel cables are rather chaotically wound.
    The disadvantage is that such cable reel cables require a greater expenditure of force for winding or unwinding, and / or there is occasionally a blockade of the unwinding and / or winding process. In this case, under certain circumstances, further unwinding and / or winding up of the cable drum cable without intervention from the outside may no longer be possible. Furthermore, by the unexpected blockage of the unwinding and / or Aufwickelungsvorganges damage to the device itself or an external installation, such as the socket to which the cable reel cable is connected, arise because, for example, the user often for convenience, the cable reel cable not manually handle, but the Device, such as a vacuum cleaner, pull behind him.
    The object of the invention is therefore to provide a cable reel cable of the type mentioned, with which the mentioned disadvantages can be avoided, with which the winding behavior of the cable reel cable can be improved.
    This is achieved by the features of claim 1 according to the invention.
    This results in the advantage that the cable reel cable with less effort and continuously off and / or can be wound up. Furthermore, the likelihood of blockage of the unwinding and / or winding operation, or jamming of the cable drum cable in the cable drum is reduced by the lower adhesive force and the associated adhesion between the individual layers of the cable drum cable. As a result, the handling of a device having this cable reel cable, greatly simplified. Furthermore, such unexpected blockages can prevent damage to the device itself or to an external electrical installation arrangement, for example a socket on which the cable reel cable is plugged. Such damaged electrical installation arrangements pose a high safety risk. In addition, the unexpected jerking of the cable reel cable prevents other objects from being affected, for example when vacuuming due to unexpected jerking of the cable reel cable caused by blockage of the cable reel. a valuable vase is overturned. By a simpler unwinding and / or winding of the cable drum cable further a possible return device of the cable drum is spared, and thus ensures a longer proper functioning of this reset device. Furthermore, this can have a restoring device a lower restoring force, whereby the handling of the device is further improved.
    The invention further relates to a method for producing a cable drum cable
    The object of this method is to produce a cable reel cable with the above-mentioned advantages with little effort and high reproducibility.
    This is achieved by the features of claim 11 according to the invention.
    This can be produced in a particularly advantageous manner, a cable reel cable with improved winding behavior and the above advantages.
    The subclaims relate to further advantageous embodiments
    3 of the invention.
    It is expressly referred to the wording of the claims, whereby the claims are hereby incorporated by reference into the description and are considered to be reproduced verbatim.
    The invention will be described in more detail with reference to the accompanying drawings, in which only preferred embodiments are shown by way of example. Showing:
    1 shows a first preferred embodiment of the cable drum cable in cross section. and
    Fig. 2 shows the detail B of Fig. 1 in an enlarged view.
    1 and 2 show a cable drum cable 1 comprising at least two electrical conductors 2 with an insulating layer 3, wherein the at least two electrical conductors 2 are embedded in a plastic sheath 4, wherein an outer surface 5 of the plastic sheath 4 at least partially surface structure elements 6 to improve the winding behavior having.
    This results in the advantage that the cable reel cable 1 with less effort and continuously off and / or can be wound up. Furthermore, due to the lower adhesive force and the associated adhesion between the individual layers of the cable drum cable 1
    Likelihood of a blockade of the unwinding and / or winding process, or a jamming of the cable drum cable 1 in the cable drum reduced. As a result, the handling of a device having this cable drum cable 1, greatly simplified. Furthermore, such unexpected blockages can prevent damage to the device itself or to an external electrical installation arrangement, for example a socket on which the cable reel cable 1 is connected. Such damaged electrical installation arrangements pose a high security risk.
    In addition, it is avoided that by the unexpected jerky tensioning of the cable drum cable 1 other objects are affected, for example, when vacuuming by an unexpected jerky tensioning of the cable drum cable 1, which by blocking the
    Cable drum was caused, a valuable vase is overturned. An easier return and / or Aufwicketn the cable reel cable 1 is further a possible return device of the. By a · Cable drum spared, and thus ensures a longer proper functioning of this reset device. Furthermore, this can have a restoring device a lower restoring force, whereby the handling of the device is further improved.
    A cable reel cable 1 is an electrical cable which is intended to be wound up and unwound several times on a cable reel. The cable reel cable 1 can preferably fulfill special requirements. The cable reel cable 1 preferably has no memory effect. This leads to a reduced looping. The cable reel cable 1 may further preferably have a tensile strength which corresponds to the tensile force requirement that occurs by the complete unwinding, and / or pulling the cable reel cable 1 until it stops. Furthermore, it is preferably provided that the cable reel cable 1 is very flexible. Thereby, a long life of a connection of the cable drum cable 1 can be achieved with a plug.
    The cable reel cable 1 comprises at least two electrical conductors 2 with an insulation layer 3.
    For example, silver and / or copper may be used as the material for the electrical conductors 2, in order to ensure a high electrical conductivity and at the same time high flexibility.
    The electrical conductor 2 may further be formed as a single wire or preferably as a stranded wire.
    Each of these at least two electrical conductors 2 is surrounded by an insulating layer 3 in order to prevent a short circuit. As a material for the insulating layer 3 plastics are particularly preferably used, since plastics ensure good insulation with high flexibility.
    The at least two electrical conductors 2, each surrounded by an insulating layer 3, are further embedded in a plastic casing 4. This plastic sheath 4 forms from the at least two electrical conductors 2, for example, a unit. Furthermore, this plastic sheath 4 offers these at least two electrical conductors 2 additional protection
    As plastic for the plastic casing 4, a plastic is preferably selected which is soft and flexible. Furthermore, an abrasion-resistant plastic is preferably selected.
    It has been found that the winding behavior of the cable drum cable 1 depends strongly on the surface properties of the outer surface 5 of the plastic casing 4, since the outer surface of the plastic casing 4 also represents the outer boundary surface of the cable drum cable 1.
    As a surface property, plastics on the one hand have the mechanical friction, which is generated by the microscopic mechanical interlocking of two surfaces and is determined by the roughness of the surfaces. Furthermore, adhesion from one plastic surface, especially from a soft plastic, to another surface, by the adhesion of the surface molecules of the plastic to the surface molecules of the other surface, plays an important role, which causes a plastic surface to adhere better to another surface and / or sticks. The adhesion depends on how close the different surface molecules come to each other. Thus, in contrast to mechanical friction, the adhesion force is greatest with two smooth surfaces, because with two smooth surfaces, the actual contact area at which the two surfaces touch is greatest. For soft materials, such as soft plastic, the actual contact area is further increased because the surface of a soft material conforms better to the shape of another surface. While the high adhesive strength of a plastic surface is advantageous in some applications, such as better grip of tires on roads or adhesive-free pressure-sensitive adhesive films, high adhesion force has a negative effect on the winding performance of a cable drum cable 1.
    Adhere by the adhesion force of the outer surface 5 of the plastic sheath 4 of the cable drum cable 1 and / or stick the individual layers of a wound cable drum cable 1 together, * * * · · t · · «· • ♦ · · * ···« ««
    ····· ♦ · * I 6 especially when these layers are still heavily compressed, which in turn leads to a higher force when unwinding the cable drum cable 1. Furthermore, by the adhesion force of the outer surface 5, the lubricity of the cable drum cable 1 is reduced, whereby, for example, when winding a cable drum cable 1 to the fact that just wound up the
    Kabeltrommelkabels 1 does not slide to a point of the cable drum on which still very little cable is wound, but adheres to that layer of the wound cable reel cable 1, which is just wound up the position of
    Cable reel cable 1 touched. This results in a fairly loose and chaotic winding a wound cable reel cable 1, which has an increased space requirement due to the loose winding. This chaotic and / or loose winding can in turn lead to a blockage of the winding process, for example, if the space in the cable drum is insufficient, and / or come to a blockage of the unwinding process, for example, if the unwound layer through the chaotic winding of others Layers is pinched.
    In order to improve the winding behavior, it is provided that an outer surface 5 of the plastic casing 4 at least in some areas has surface structure elements 6 for improving the winding behavior.
    These surface structure elements 6 are preferably designed to reduce the actual contact surface of the outer surface 5 of the plastic casing 4.
    These surface structure elements 6 can be bulges and / or indentations in various forms. For example, the bulges and / or indentations may be acicular, linear, wavy, and / or planar, and / or may have a more complex pattern, such as a grid pattern or other pattern. Thereby, the contact surface of the outer surface 5 is reduced with a different surface, and concomitantly the adhesion force, since the outer surface 5 either rests on a bulge and / or the surface of a recess does not contribute to the contact surface.
    As an example of surface structure elements 6, which are formed as linear indentations, grooves may be mentioned,
    7 which, for example, can extend transversely or parallel to the longitudinal axis of the cable drum cable 1, or helically around the longitudinal axis of the cable drum cable 1.
    According to the first particularly preferred embodiment of the invention in Fig. 1 and Fig. 2 it can be provided that the
    Surface structure elements 6 include a plurality of longitudinal grooves 7 in the direction of the longitudinal axis of the cable drum cable 1. As a result, on the one hand the winding behavior of the cable drum cable 1 is improved, since the contact surface of the outer surface 5 is smaller, on the other hand, there is no additional mechanical friction between the outer surface 5 and ground when the cable drum cable 1 is looped along the longitudinal axis of the cable drum cable 1 on a substrate.
    According to the first preferred embodiment of the invention in Fig. 1 it can be provided that the longitudinal grooves 7 are distributed over the circumference of the outer surface 5 substantially equal. This results in a uniformly distributed over the outer surface 5 reduction of adhesion forces, which is why the force required to unroll the cable drum cable 1 is more uniform, whereby the winding behavior of the cable drum cable 1 is further improved.
    The profile of the cross section of the outer surface 5 is preferably formed such that the contact surface of the outer surfaces 5 of two adjacent along the longitudinal axis cable drum cables 1 is very low. Weiniger advantageous appears a sinusoidal profile of the cross section of the outer surface 5, since in this case the outer surfaces 5 of two adjacent along their longitudinal axis cable drum cables 1 engage and thus increase the contact surface.
    According to the first preferred embodiment of the invention in Fig. 1 it can be provided that the longitudinal grooves 7 have a substantially V-shaped profile. Thereby, a meshing of the longitudinal grooves 7 is prevented by adjacent the longitudinal axis adjacent cable drum cables 1, whereby a good winding behavior can be achieved.
    It can preferably be provided that the tip of the substantially V-shaped profile of the longitudinal grooves 7 is flattened, as shown in FIG. 2 is apparent. As a result, on the one hand the deposition of dirt and dirt in the longitudinal grooves 7 is prevented, on the other hand, the risk of cracking, which is given at a tapered groove, prevented, whereby the cable reel cable 1 has a longer life.
    The contact surface of the outer surface 5 of the cable drum cable 1 with a surface which is formed like this outer surface 5, further depends on the profile of the intermediate regions 8 of the longitudinal grooves 7. The intermediate areas 8 of the longitudinal grooves 7 may be formed, for example, trapezoidal. However, it has been found that a convex shape of the profile of the intermediate regions 8 of the longitudinal grooves 7 is advantageous, since the contact surface of two cable drum cables 1 resting along their longitudinal axis is thereby small.
    Since the material of the plastic casing 4 is yielding, it is particularly advantageous that those regions of the profile of the intermediate regions 8 of the longitudinal grooves 7, which are provided so that two closely adjacent cable drum cables 1 touch along their longitudinal axis, have the highest possible convex curvature , As a result, the contact surface of the outer surface 5, even if the two cable drum cables 1 are strongly pressed together and the outer surface 5 deformed because of this, remains low.
    According to the first preferred embodiment of the invention in Fig. 1 it can be provided that between two adjacent longitudinal grooves 7 intermediate regions 8 are arranged with a rounded profile. As a result, on the one hand a strong abrasion of these intermediate regions 8 is prevented, on the other hand, the mechanical friction is reduced by the renunciation of edges.
    These intermediate regions 8 with a rounded profile are preferably convexly convex towards the outside according to FIG.
    Preferably, it may further be provided that - seen along the circumference of the outer surface 5 - at least 30, in particular at least 50 longitudinal grooves 7 are arranged. As a result, an optimal reduction of the contact surface can be achieved.
    In a development of the invention, it can be provided that the depth of the longitudinal grooves 7, as seen from the highest point of the intermediate region 8, is "*
    • * * * * · l '· · I «I * * * ·,. Is at least 50 μm, in particular at least 100 μm, and particularly preferably at least 200 μm. As a result, an optimal balance between the improvement of the winding behavior and a sufficient minimum thickness of the plastic casing 4 can likewise be achieved.
    There are cable drums known which have a rotatably mounted around a Abspulachse drum core.
    In such a cable drum it is preferably provided that a cable reel cable 1, according to the subject invention, is arranged on the drum core. As a result, this cable drum has an improved winding behavior.
    Preferably, it can further be provided that the cable drum comprises an electrical connection element for the positionally fixed contacting of the cable drum cable 1. Such connection elements may be, for example, slip rings or abrasive bristles. As a result, an electrical contacting of the cable drum cable 1 by a device in which the cable drum is arranged, possible without the electrical contact between the device and cable reel cable is interrupted by an intended unwinding and / or winding.
    Furthermore, it is preferably provided that the rotation of the drum core is operatively connected to the Abspulachse with a spring element. Such a spring element may preferably be part of a restoring device which rewinds the cable reel cable 1 continuously or after actuation of a control element onto the cable reel.
    There are known household appliances, which have cable drums. As examples may be mentioned vacuum cleaners, toasters, mixers or irons, which may have a cable drum for easier handling. In such household appliances is provided in the final assembled state that the cable reel cable 1 is repeatedly off and wound up.
    Preferably, a household appliance with a cable drum, according to the subject invention, be provided. As a result, the advantages of the cable drum cable 1 according to the invention can be achieved in this household appliance.
    Methods are known for making cable reel cable 1, • * * »« < I φ φ φ * * * ίό ίό ίό ίό ίό ίό ίό ίό ίό ίό ίό ίό ίό wenigstens wenigstens wenigstens wenigstens wenigstens wenigstens wenigstens wenigstens wenigstens wenigstens wenigstens wenigstens wenigstens wenigstens wenigstens wenigstens wenigstens wenigstens wenigstens wenigstens 2 are provided with an insulating layer 3 in an extrusion step with a plastic sheath 4.
    For example, cable reel cable 1 in this
    Extrusion step by means of an extrusion die, which produces a profile of the outer surfaces 5 in the extrusion step, are provided with surface structure elements 6.
    To produce a cable drum cable 1, it is preferably provided that after the extrusion step, the outer surface 5 of the plastic casing 4 is at least partially provided with surface structure elements 6 for improving the winding behavior. Thus, the process parameters of the extrusion step, regardless of the way of applying the
    Surface structure elements 6 are selected.
    Particularly preferably, it is provided that the surface structure elements 6 are applied by means of at least one embossing wheel. As a result, existing production plants can be converted without much effort. As a result, the production between conventional cable drum cables 1 and those with surface structure elements 6 can be changed without effort and interruptions. Furthermore, the fast interchangeability of embossing wheels between a plurality of different and tailored to the application surface structure elements 6 can be changed quickly. Furthermore, burr-free outer surfaces 5 can be produced by stamping wheels with high reproducibility. Furthermore, embossing wheels offer the possibility of applying surface structure elements 6 with complex shapes in comparison to an extrusion die.
    Particularly preferred is further provided that a plurality of staggered embossing wheels are used. As a result, surface structure elements 6, for example in the form of longitudinal grooves 7, can advantageously be distributed essentially uniformly over the circumference of the outer surface.
    Furthermore, it is particularly preferably provided that the temperature of the outer surface 5 in the application of the surface structure elements 6 at least 100 ° C, in particular 150 ° C, is selected. As a result, the outer surface 5 is still soft and can be molded well and permanently.
    Furthermore, the surface structure elements 6 can thereby be applied immediately after the extrusion step, whereby the process takes less time.
    Further embodiments according to the invention have only a part of the features described, wherein each feature combination, in particular also of various described embodiments, can be provided.
