The invention also relates to a fastening arrangement (2) having such a cable (1).

Description

The invention relates to a cable with the features of claim 1. Furthermore, the invention relates to a fastening arrangement with the features of claim 8.

Cable looms are to be attached in a motor vehicle, in particular in a motor vehicle, to the body and / or to another motor vehicle component so that the cable looms are not loose or undefined in the vehicle, which could cause them to move in an uncontrolled manner. On the one hand, this serves to maintain the defined position of the cable harnesses in order to ensure a functioning package and proper installation and handling. This also prevents damage to the respective cable loom, the contacts and plugs, the seals and the surrounding components due to uncontrolled movements of the respective cable loom. Other requirements, such as avoidance of acoustic problems (NVH: Noise Vibration Harshness), compliance with EMC limit values (EMC: electromagnetic compatibility), ensuring freedom of movement of components, etc., also play a role.

Nowadays, cable harnesses in vehicle construction, in particular series vehicle production, are fastened by fastening semi-finished products (clips, holders, etc.) to the respective cable harness, by means of which the cable harness is then fastened to the body or to the motor vehicle component. The respective semi-finished fastening product is usually attached to the cable loom by means of cable ties, wrapping tapes, clamps and / or even by clamping the cable loom between (screwable) clamping jaws.

• - wie bereits weiter oben beschrieben - zu besonders hohen Einschnürungskräften bzw. Einklemmkräften, was das Risiko der Beschädigung des Kabelstrangs weiter erhöht. Zugleich sind dann die Befestigungshalbzeuge besonders hohen Haltekräften ausgesetzt, sodass die Befestigungshalbzeuge massiver und infolgedessen materialintensiver herzustellen sind. In weiterer Folge sind aufzuwendende Montagekräfte besonders hoch und das mit den herkömmlichen Befestigungshalbzeugen ausgerüstete Kraftfahrzeug ist besonders schwer. Analog sind die Befestigungsmittel, die die Verbindung zwischen den Befestigungshalbzeugen und dem Kabelstrang realisieren, ebenfalls besonders stabil und dadurch entsprechend masseintensiv auszubilden.

With the solutions known nowadays, however, it is disadvantageous that the semi-finished fastening products or their fastening means (cable ties, wrapping tapes, etc.) apply a clamping force and / or a constriction force to the cable loom, so that there is a risk of damage to the cable loom due to those forces. Furthermore, the assembly effort in connection with the conventional fastening semi-finished products is particularly high, since the respective cable loom is to be fastened to the motor vehicle component by means of a multiplicity of fastening elements. In addition, it is only possible using the conventional fastening semi-finished products to produce punctual connections between the cable harness and the motor vehicle component, so that the respective cable harness is only held punctually and not over its entire length on the motor vehicle component or on the motor vehicle components. Correspondingly, higher holding forces are also implemented at the individual fastening points in order to ensure a secure fit of the cable loom. This in turn leads to the respective semi-finished fastening product

• - as already described above - to particularly high constriction forces or trapping forces, which further increases the risk of damage to the cable loom. At the same time, the fastening semi-finished products are then exposed to particularly high holding forces, so that the fastening semi-finished products are more massive and consequently more material-intensive to manufacture. As a further consequence, the assembly forces to be expended are particularly high and the motor vehicle equipped with the conventional fastening semi-finished products is particularly heavy. Similarly, the fastening means, which establish the connection between the fastening semifinished products and the cable loom, are also to be particularly stable and therefore correspondingly massive.

Furthermore, due to manufacturing and joining tolerances - both in the production of individual parts and in assemblies - it can be a disadvantage if the fastening semi-finished products are firmly connected to the cable harness, i.e. cannot be moved or do not provide any compensation for such tolerances. This further complicates the assembly of the respective cable loom in the motor vehicle and / or requires very strict adherence to tolerances in all components of the motor vehicle and in the assembly and / or joining processes in the manufacture of the motor vehicle.

the DE 25 30 235 A1 discloses a self-adhesive cable and cable fasteners. Here, an outer sheath of the cable is provided with an adhesive layer tailored in terms of its properties to the intended use, duration of use of the cable and the intended mounting surface, this adhesive layer being supported by a peelable film against premature drying and setting of the adhesive. However, the production of such a conventional self-adhesive cable is particularly complex. Furthermore, once activated, the adhesive is subject to a constant aging process, whereby the adhesive loses its adhesive strength. In other words, the adhesive connection between the cable and the component to which the component is adhered is limited to the durability of the adhesive and, in particular, is inferior to a mechanical connection with regard to durability.

the DE 103 15 316 A1 discloses a flat cable fastening arrangement with a substantially planar fastening structure part and a flat cable comprising a number of parallel spaced apart conductors embedded in insulating material, wherein for fastening the flat cable on the fastening structure part, a plurality of in each has an opening in the insulating material of the flat cable engaging fastening bumps. In this conventional flat cable fastening arrangement, the fastening bumps of the fastening structural part extend completely through a cross section of the flat cable, weak points being created in the insulating material of the flat cable.

The object of the invention is to provide a cable that can be used in a particularly versatile manner and can be securely held, as well as a fastening arrangement with such a cable that can be used in a particularly versatile manner, in particular in each case for motor vehicle construction.

This object is achieved by a cable with the features specified in claim 1 and by a fastening arrangement with the features specified in claim 8. Features, advantages and advantageous configurations of the cable according to the invention are to be regarded as features, advantages and advantageous configurations of the fastening arrangement according to the invention and vice versa.

According to the invention, a cable with a core and with a sheathing is provided, which can be rigid or bendable or pliable as intended. Here, the sheathing surrounds the core along a direction of longitudinal extent in such a way that the core is completely enclosed by the sheathing in a cross-sectional figure of the cable arranged perpendicular to the direction of longitudinal extent. In other words, the soul is embedded in a material of the sheath. In particular, the core and the casing can then be materially connected to one another. The cable further has a fastening element formed on the sheath.

The cable can have more than one soul, especially one via number 2 outgoing multitude of souls, so that the soul is then embedded in the material of the casing or the souls are embedded in the material of the casing. The sheathing then encompasses the core or cores along the longitudinal direction of the core (s) or the cable. Optionally, the cable can have a shielding element which, in particular, together with the core or cores, can be encompassed by the sheathing or embedded in it.

In order to make the cable particularly versatile and securely holdable, the invention provides that the fastening element is integrated into the sheath and protrudes from an outer surface of the sheath and corresponds to the fastening of the cable to a holding element.

The holding element - not belonging to the cable - can be arranged, for example, on a component of a motor vehicle, so that the cable can be fastened to the motor vehicle component by means of the fastening element during manufacture of the motor vehicle. In other words, the fastening element and the holding element together form a fastening device when the fastening element and the holding element are fastened to one another. In order to form the fastening device, the fastening element and the holding element can be positively connected to one another, for example, by means of respective form-fitting elements, they can engage or engage behind one another, and / or be non-positively connected to one another, e.g.

The force fit and / or form fit also enables the fastening device to be opened as intended and non-destructive, for example for maintenance / repair purposes, although the holder between the fastening element and the holding element are particularly efficiently secured against unintentional loosening from one another when the fastening device is closed. In other words, through the force fit and / or form fit, the fastening device offers the possibility of releasably fixing the cable and the holding element to one another, wherein the fastening element or the cable and the holding element are non-destructive, i.e. with no material separation (cutting, etc.) , are detachable from each other.

Since the fastening element is integrated into the sheathing, fastening semi-finished products separate from the cable and from the holding element are obsolete. This makes handling the cable and processing it, such as installing it in the motor vehicle, particularly simple, since a worker or fitter does not need to handle and / or position the semi-finished fastening products during or before handling the cable. The fastening of the cable to the holding element or to the motor vehicle component is particularly efficient, as a result of which a cycle time for the cable fastening, for example in a series production of vehicles, is advantageously reduced. Furthermore, the cable can be held particularly securely on the holding element, since the fastening element is integrated into the sheathing of the cable.

A respective shape of the cross-sectional figure of the casing and the core (s) can - but need not - be the same. For example, the cable can be given a desired external shape and / or surface quality by using the Shape of the cross-sectional figure of the jacket is selected accordingly. This is especially true if, for example due to boundary conditions in the manufacture of the soul (s), there are limits to a choice of the cross-sectional shape of the soul (s).

In a further embodiment of the cable, the fastening element and the sheathing are materially connected to one another, preferably formed in one piece with one another. This ensures a particularly secure and permanent connection between the fastening element and the casing. There is particularly little risk of the fastening element and the casing becoming detached from one another. With regard to the motor vehicle - especially manufactured in series vehicle construction - in which the use of the cable is preferred, this is of particular advantage, since a particularly favorable NVH quality (Noise Vibration Harshness) of the motor vehicle is taken into account. In addition, a particularly long shelf life of that NVH quality is guaranteed.

It can furthermore be provided that a material of the fastening element and a material of the casing have the same material properties. The respective material properties, such as the surface properties, resistance to bending, resistance to elongation, resistance to breakage, resistance to torsion, etc., of the fastening element and the sheathing correspond to one another and do not interfere with one another. Accordingly, the cable is particularly easy to process, for example built-in.

In particular, the fastening element and the casing can be formed from the same material. This enables a particularly simple and efficient production of the cable, since only a few different materials need to be used, namely one for each core and a common one for the sheathing and the fastening element. If, in the simplest case, the cable only has exactly one core, the cable can then be produced using only two different materials.

As an alternative to the same material properties, it can be provided that the material of the fastening element and the material of the casing have different material properties from one another. For the manufacture of the cable, in particular with the sheathing and the fastening element formed integrally with one another, it is advantageous if the material of the fastening element and the material of the sheathing are the same, but different material properties, in particular different materials, do not preclude that the fastening element and the casing are made in one piece with one another.

The different material properties of the fastening element and those of the sheathing can complement one another. If, for example, two material properties desired for the cable are mutually exclusive in the material of the sheath, for example resistance to bending and an electrical insulation effect, the material of the sheath can be designed according to one of the desired material properties (in the example a high electrical insulation effect). The other - still missing or only inadequately implemented - material property (in the example a high resistance to bending) can then be imparted to the cable by means of the material of the fastening element.

As already mentioned above, the fastening element and the casing can be formed integrally with one another even if these two are different materials.

In a further embodiment of the cable, the fastening element has a form-fit element which corresponds to a form-fit element of the holding element. In this way, the form-fit element of the cable or of the fastening element and the form-fit element of the holding element form a form fit with one another when the fastening element and the holding element are fastened to one another. As a result of this form fit between the holding element and the fastening element, the cable and the holding element hold one another particularly reliably. The risk that the cable will inadvertently detach itself from the holding element or from the motor vehicle component is particularly low, which again has a favorable effect on the particularly long durability of the NVH quality.

In addition, the cable can have a further fastening element, hereinafter referred to as “second fastening element”, which corresponds to the first fastening element, which is the fastening element described above. In particular, a plurality of fastening elements beyond the number 2 is provided on a single cable.

“Corresponding to one another” is understood on the one hand to mean that the first fastening element and the second fastening element - each taken individually - can be fastened to one another in a non-positive and / or positive manner in a predefined manner or form a fastening device with one another. This means that if there are two or more cables or cable sections, these can be special can be securely fastened to one another simply and with little effort by means of the fastening elements, as a result of which a particularly stable cable harness can be formed which can have two or a plurality of cables exceeding two. The cables are attached to one another in a particularly advantageous manner.

As an alternative or in addition, “corresponding to one another” is understood to mean that the first fastening element and the second fastening element are of identical design. In other words, the single cable then has at least two fastening elements that are spaced apart from one another and, in particular, can be of the same shape.

In a further embodiment of the cable, the fastening element protrudes therefrom in a fastening region of the sheathing, which is formed along at least a portion of a longitudinal extension of the cable by at least a portion of the outer jacket surface. If both the first and the second fastening element are present, the first fastening element and the second fastening element protrude therefrom in a respective fastening area of the sheathing, which is each formed along at least a respective part of the longitudinal extension of the cable by at least a respective part of the outer jacket surface. This means that the casing or its outer jacket surface has the fastening area and at least one free area, so that the outer jacket surface is formed by the fastening area and the free area. In particular, it is provided that the fastening area is arranged along the direction of longitudinal extent or parallel thereto and directly or immediately adjoins the free area. In other words, the free area and the fastening area merge, in particular seamlessly, into one another.

The fastening area can have a longitudinal dimension (or a length) along the longitudinal extension direction of the cable which corresponds to a longitudinal extension (or a length) of the cable or cable section. In other words, the fastening area extends continuously over the entire length of the cable. The cable can thus be fastened to the holding element particularly reliably or securely over its entire length.

Alternatively, it can be provided that the fastening area is interrupted by at least one free area along the longitudinal extension of the cable. Furthermore, the fastening area can be interrupted by more than one free area, in particular regularly. If both at least one first and at least one second fastening element are formed on the cable, it can be provided that the first and the second fastening elements are arranged alternately along the longitudinal extension direction of the cable. The first and the second fastening elements share a common fastening area.

In this way, the cable can be manufactured in a particularly material-efficient manner, so that the cable can ultimately be designed to be particularly efficient in terms of mass. If the cable configured in this way is then used or installed in the motor vehicle, the motor vehicle is particularly light as a result. This means that the motor vehicle can be operated in a particularly energy-efficient or fuel-efficient manner and / or with low emissions.

The invention also relates to a fastening arrangement which has a cable and a holding element. The cable has a core and a sheathing, the core being encompassed by the sheathing along a longitudinal extension direction of the core, in such a way that in a cross-sectional figure of the cable arranged perpendicular to the longitudinal extension direction, the core is completely enclosed by the sheathing, with the cable continuing a having a fastening element formed on the sheathing, which is integrated into the sheathing and protrudes from an outer circumferential surface of the sheathing and corresponds therewith for fastening the cable to the holding element. The holding element of the fastening arrangement corresponds to the fastening element of the cable, the fastening element of the cable and the holding element of the fastening arrangement forming a fastening device by means of which the cable and the holding element are fastened to one another, in particular along the (respective) longitudinal extension direction of the cable or the Fasteners.

In this way, a particularly versatile fastening arrangement is created in which the cable is securely held.

In a further embodiment of the fastening arrangement, the holding element is arranged on a component for a motor vehicle, in particular connected to the component in a materially bonded manner, preferably formed in one piece with it. This results in a particularly stable connection between the cable and the motor vehicle component.

The fastening arrangement can comprise a further cable, hereinafter referred to as “second cable”, this and the cable, which is the first cable, being fastened to one another via their respective fastening element, in particular along the respective longitudinal extension direction of the cables. That means that the fastening element of the first cable and the fastening element of the second cable correspond to one another. This makes it possible to mechanically connect cable to cable to one another, as a result of which, for example, a particularly stable cable harness can be formed which has more than a single cable, in particular a multiplicity of cables. Furthermore, holding elements can be saved in this way, which further supports a particularly mass-efficient production of the motor vehicle. In this case, the cables are positioned and held parallel to one another / to one another at least in some areas along their respective longitudinal extension direction.

The invention also includes the combinations of the features of the described embodiments.

Furthermore, the described embodiment can also be supplemented by further features of the invention that have already been described.

In the figures, functionally identical elements are each provided with the same reference symbols.

The following are a cable 1 and a mounting arrangement 2 described together with each other.

1 Figure 3 shows a sectional view of the cable 1 with fasteners 3 and a holding element corresponding therewith 4th . This in 1 shown cables 1 has a soul 5 on as well as a sheath 6th . A longitudinal direction 7th of the cable 1 or the soul 5 stands perpendicular to the plane of the drawing and is in 11 as in 12th recognizable. In the in 1 cross-sectional figure shown 8th of the cable 1 can be seen that the sheathing 6th the soul 5 along the longitudinal direction 7th so embraces that the soul 5 completely from the sheath 6th is enclosed.

The fastener 3 is in the sheath 6th integrated and jumps from an outer circumferential surface 9 the sheath 6th emerged. For fastening or fastening the cable 1 on the holding element 4th that is not about the cable 1 belongs, correspond to the holding element 4th and the fastener 3 together. The outer jacket surface 9 or a contour of the same can be within a material of the sheathing 6th get lost. In other words, one can come from outside the cable 1 visible contour of the outer surface 9 continue in an interior of the sheath (imaginary).

Is the cable 1 for example designed as an electric cable, forms the soul 5 a current conducting element, for example made of a metallic material. In this case, the sheathing 6th commonly called "isolation".

The cable is used for data transmission 1 suitable if it is designed as a data cable. Then the soul is 5 designed as the current conducting element (as described above) or as an optical waveguide.

The sheath 6th and the soul 5 can be formed integrally with one another, then forms an outer layer of the cable 1 the sheath 6th for an inner layer of the cable that is encompassed by the outer layer and directly bonded to the outer layer 1 . This is the case, for example, when the cable 1 comprises the optical waveguide, which can be made from a glass and / or from a plastic, wherein the The outer layer and the inner layer, that is, the soul 5 and the sheath 6th , can even be formed from the same material.

The cable 1 can also be designed as a hose or an at least partially bendable tube. The soul 5 is then a channel element, i.e. a material-free space. The channel element that is covered by the sheath 6th surrounded and thereby limited, can be flowed through by a flow material, such as a fluid and / or (powder-like) bulk material, etc.

Alternatively, an elongated tension element can be formed in the channel element, which extends along the longitudinal direction 7th of the cable 1 in relation to the sheath 6th is movable. In other words, the sheathing 6th and the soul forming the elongate tension element 5 together form a Bowden cable.

The cable 1 can be made rigid at least in some areas. Alternatively or additionally, the cable 1 be designed to be flexible or at least bendable or deformable in a non-destructive manner, as intended, at least up to a breaking or tearing limit.

The cable 1 can be more than one soul 5 have (see 4th , 5 , 6th ), especially a multitude of souls 5 , being the souls 5 then from the sheath 6th are edged together. It is conceivable to have different types of cores, for example an elongated tension element and a current conducting element separate therefrom, with one another in a common casing 6th to arrange. May the souls 5 in the common sheath 6th do not touch each other, for example to short-circuit the individual souls 5 to exclude are the souls 5 in the common sheath 6th transversely to their respective longitudinal direction 7th spaced from each other, for example via the material of the sheath 6th isolated from each other. That means that between souls 5 the material of the sheath 6th is arranged.

In a first embodiment of the fastening element 3 this has a groove 11 on, the two groove walls 10 includes. The groove walls 10 are in the sheath 6th integrated and jump from the outer surface 9 the sheath 6th emerged. The groove walls form 10 the groove 11 that are used to attach the cable 1 on which not to the cable 1 belonging holding element 4th corresponds with this.

Alternatively or additionally, the fastening element comprises 3 at least one in the sheath 6th integrated and from the outer jacket surface 9 the sheath 6th protruding spring 12th . Assigns the fastener 3 both the at least one groove 11 as well as the at least one feather 12th on, it is provided that the groove 11 and the pen 12th correspond with each other. Is there another or second cable that is the same as the cable 1 is formed, the cable can 1 and the at least one further cable over the respective fastening elements 3 or via the grooves 11 and the feathers 12th be attached to each other. Such a feather 12th is for the first time in 2 shown.

A respective outer circumference 13th the sheath 6th and a respective outer circumference 14th can be in the cross-sectional figure 8th as an oval, in particular an oval without a symmetry axis, as an ellipse, as a circle, etc. Furthermore, the respective outer circumference 13th , 14th the sheath 6th or the soul 5 or souls 5 , in the cross-sectional figure 8th as a closed and not overturned, in particular regular polygon, for example as a triangle, as a rectangle (in particular rectangle or square), as a pentagon, as a hexagon and so on. The outer perimeter arises 13th the sheath 6th as a flat rectangle, as in 1 , 2 and 3 shown is the cable 1 designed as a so-called flat cable.

The respective shape of the cross-sectional figure 8th or the type of outer circumferential lines 13th , 14th the sheath 6th and the soul (s) 5 can - but do not have to - be the same.

The fastener 3 and the sheath 6th are cohesively connected to one another, in the present case formed in one piece with one another. It can be provided, for example, that the casing 6th and the fastener 3 fused, welded, glued to one another, joined by means of vulcanization, etc. and / or connected to one another in some other way. Are the fastener 3 and the sheath 6th formed in one piece with one another, as in the present case, it is possible - but not mandatory - that the components formed in one piece with one another have the same material. In other words, the components formed in one piece with one another, for example the fastening element 3 and the sheath 6th , be of different material.

A generating or manufacturing of the fastening element 3 along with the sheath 6th can for example take place by means of coextrusion. It is also conceivable that the cable 1 is made by means of a single extrusion by the soul 5 or souls 5 the sheath 6th and the fastener 3 are coextruded with each other. When coextruding it is possible - but not mandatory - for the components coextruded with one another to have the same material. The components coextruded with one another, for example the fastener 3 , the soul or souls 5 as well as the sheathing 6th can each be of different material.

In 1 , 2 and 3 is also a shielding element 15th shown that together with the soul 5 or with the souls 5 into the sheath 6th or is embedded in the material.

As the material for the sheathing 6th For example, a plastic such as a thermoplastic, a thermosetting plastic, an elastomer or a mixed material comprising at least two of the three may be considered. The same applies to the material of the fastening element 3 . It can be provided that the material of the fastening element 3 and the material of the sheath 6th have the same material properties, in particular the fastening element 3 and the sheath 6th be made of the same material. Alternatively, it can be provided that the material of the fastening element 3 and the material of the sheath 6th have mutually different material properties, in particular the material of the fastening element 3 and the material of the sheath 6th different materials from each other.

In a further embodiment it is provided that the fastening element 3 a form-fit element 16 having that with a form-fitting element 17th of the holding element 4th corresponds. Are the cables 1 and the holding element 4th to the in 3 mounting arrangement shown 2 put together, the form-fitting elements grip 16 , 17th into each other, whereby the form-locking elements 16 , 17th form a form fit with each other, via which the cable 1 by means of the corresponding fastening element 3 on and / or in the holding element 4th is held. In other words, the interlocking elements convey 16 , 17th in the mounting arrangement 2 a form fit between the cable 1 and the holding element 4th .

In 1 it is also shown that the cable 1 Another fastening element, hereinafter referred to as “second fastening element” 18th having that with the first fastening element 3 corresponds. That means the second fastener 18th and the first fastener 3 can be designed the same. In this case, the second fastening element 18th the groove 11 on when the first fastener 3 the groove 11 having. However, the first fastener has 3 the feather 12th so also has the second fastening element 18th the feather 12th on. In an alternative embodiment, the fastening elements 3 , 18th be designed differently from each other. Such a case is for example in 2 shown. It can be seen that the first fastening element 3 the feather 12th comprises, whereas the second fastening element 18th the groove 11 includes.

Is there another cable 19th before, the same as the cable 1 is formed, are the cable 1 and the other cable 19th , especially in the mounting arrangement 2 , by means of the respective fastening elements 3 , 18th attached to one another or attachable, as the fastening elements 3 , 18th of the cable 1 and the fasteners 3 , 18th of the other cable 19th correspond with each other. In particular, the respective form-fit elements correspond 16 of the cable 1 and that of the other cable 19th .

At the in 3 The fastening arrangement shown can also be seen that the cable 1 between the further or second cable 19th and yet another, e.g. third, cable 20th is arranged. This is where the cable functions 1 between the second cable 19th and the third cable 20th as an adapter as the cables 19th , 20th facing fasteners 3 , 18th which are incompatible with one another or do not correspond to one another. With appropriate selection of the fastening elements 3 , 18th of the cable 1 so the further or second cable 19th and the further or third cable 20th associate.

2 shows the cable in a sectional view 1 and the holding element 4th , which are each formed in a further embodiment. This in 2 shown cables 1 differs from the one in 1 shown cable 1 in that there are two differently designed fastening elements 3 , 18th having. This in 2 shown holding element 4th differs from the one in 1 shown holding element 4th in that there is another form-locking element 17th has as the holding element 4th the 1 .

In 3 Figure 3 is a sectional view of the mounting arrangement 2 with the cable 1 , with the (further or second) cable 19th and / or with the holding element 4th as well as with the (still further or third) cable 20th shown. It can be seen that the form-locking elements 16 , 17th of the cable 1 and the holding element 4th form the form fit with each other, whereby the cable 1 and the holding element 4th are securely attached to each other. In the case of the holding element 4th it is in particular a component for a motor vehicle which can be designed as a motor vehicle, that is to say a passenger vehicle and / or a truck. In particular, it is provided that the motor vehicle has an electrical energy storage device and an electrical drive unit, for example an electric motor, the electrical energy storage device, which comprises at least one electrical accumulator, and the electric motor via cables, in particular via at least the cable 1 , are connected or connectable to one another. Accordingly, the electrically drivable motor vehicle or motor vehicle can be a so-called high-voltage vehicle (BEV: Battery Electric Vehicle, PHEV: Plug-in Hybrid Electric Vehicle, HEV: Hybrid Electric Vehicle, FCEV: Fuel Cell Electric Vehicle, etc.) . That means the cable 1 or the fastening arrangement 2 is used or can be used to convey high voltage or high voltage and / or (high) current between the electrical energy storage device and the electric motor. Furthermore, the cable 1 or the fastening arrangement 2 for conveying medium voltage or medium voltage (48 volts) or low voltage or low voltage ( 12th Volts, 24 volts).
