Definitions

  • the invention relates to a protective jacket for wiring harnesses of motor vehicles, with at least one flexible carrier.

  • Such protective sheathing is generally not connected to the cable harness in question and to be bundled in order to maintain the required flexibility of the cable harness when it is installed in the motor vehicle, although in practice some connections also occur.
  • vibrations, rattling noises, signs of abrasion, etc. can be avoided, the individual cables of the cable harness also being mutually fixed in the form of loose bundling.
  • the known protective sheaths have proven themselves in principle, but there is room for improvement in terms of their assembly on the cable harness to be assembled. This is mostly due to the fact that they are inflexible or have too little dimensional stability to ensure processing by hand.
  • mounting aids are increasingly used in practice, e.g. back in the form of double-sided self-adhesive mounting strips. This is intended to achieve a first fixation on or on the cable set. The freedom of movement of the cable set is restricted for certain applications or is even completely excluded.
  • there is additional processing effort because masking papers of the mounting strips have to be removed and disposed of.
  • the installation space available for the cable harnesses decreases from vehicle generation to vehicle generation because more and more additional units have to be accommodated in the vehicle body. At the same time, this increases the number of cables to be processed and their length. In order to be able to meet these conflicting requirements, it is necessary to flexibly wrap the protective sheath around the cable harness or the cables to be bundled.
  • the problem is a generic protective sheath for wiring harnesses of motor vehicles according to the invention characterized in that the carrier has at least one manually plastically deformable fastening element for its comprehensive attachment to the respective wiring harness.
  • the manually plastically deformable fastening element consequently assumes a shape during the assembly of the protective casing according to the invention, which is given to it (the fastening element) by an assembly worker.
  • the manually achievable plastic deformation ensures this. This means that the fastening element can already be plastically deformed with forces of a few Newtons, which can usually be applied by hand, so it does not return elastically to its initial state.
  • the fastening element generally has a manually plastically deformable core as well as a covering that receives the core. It goes without saying that the fastening element can also do without a sheath and, for example, uses a multi-layer flexible core.

  • a metal wire or metal strip of small diameter has proven to be favorable.
  • the core can be made from one or more copper wires with one Represent diameters of approx. 1 mm, which have the necessary bendability by hand. As a result, there is already a practical, manually plastically deformable fastening element.

  • Additional (not plastically deformable) fastening elements can be added to these fastening elements according to the invention, e.g. Velcro straps, cable ties, etc.
  • the respective fastening elements are each connected to the carrier in transverse extension, i.e. they run across the cable harness or the cables to be bundled and the carrier.
  • the fastening elements can be fixed adhesively, although other types of connection such as a riveted connection, a (plastic) welded connection, etc. are also conceivable.
  • the fastening elements are mainly arranged transversely to the longitudinal extent of the flat flexible carrier, specifically on the side of the carrier facing the cable harness or on its side facing away from the cable harness.
  • fastening elements it is also within the scope of the invention to insert individual fastening elements on the facing side and individual on the opposite side of the carrier To be compared to the wiring harness. For reasons of simple and inexpensive production, however, the decision will mostly be made for only one side, and in most cases the inside of the carrier facing the wiring harness.
  • the sheath that receives the core of the fastener if it completely encloses the core, ensures that the core does not come into contact with the cable harness to be protected. Damage to the cable harness from the fastening element provided according to the invention can therefore be ruled out as a result of the covering.

  • the protective sheath described can already be properly fixed to the wiring harness by the manually plastically deformable fastening element, it is advisable for individual applications to provide a closure device in addition to the fastening element at least in some areas.
  • This closure device may be designed as a region-specific Velcro fastener. But a zipper, snap fastener or comparable soluble connections are also conceivable and are covered. Characterized in that the protective sheath according to the invention due to the manually plastically deformable fastening element a pre-fixation on Cable bundle, the handling of the optional locking device is considerably simplified. This represents a further advantage over the known and initially described embodiments.
  • the closure device can be simply defined by equipping the carrier on at least one longitudinal edge with associated hooks on the inside.
  • These hooks can be part of a micro-Velcro tape, which is designed as a two-dimensional film made of plastic with adhesive hooks formed in one go. This means that the hooks responsible for the Velcro effect in the third dimension are produced in an integrated process step during the extrusion process, so that such a micro-Velcro tape carrier can be realized extremely inexpensively.
  • the invention also relates to an associated production method for such a protective sheath, as described in claims 9ff.
  • a protective jacket is made available that is easy to produce and is particularly convincing due to its uncomplicated assembly. This is ensured by the manually plastically deformable fastening element, with the help of which the protective sheath is fixed around the respective cable harness. Additional assembly aids are not required. Because the protective sheath is not connected to the cable harness, even demanding laying work, such as tight bending radii, and the protective sheath can also be moved in the longitudinal direction of the cable harness if this should be necessary.
  • the carrier and the cover are designed as interconnected flat structures made of, for example, velor, fabric, fleece, felt, foil, etc. Both fabrics can be made of the same or different materials. Because the fastening element is accommodated between the carrier and the cover, it is accommodated in a protected manner.
  • the manually plastically deformable fastening element can be opened by the same force as when it is applied around it and with it the protective sheath, if this should be necessary. This is facilitated by the fact that the optional locking device is also designed to be detachable or apparently.

  • the carrier 2 has at least one fastening element 3.
  • the fastening element 3 can be plastically deformed manually, ie can be brought into a desired shape by an operator by hand. Because the fastening element 3 is connected to the carrier 2, the carrier 2 follows the shape predetermined by the fastening element 3. The same applies to the protective casing as a whole.
  • a plurality of fastening elements 3 are connected to the carrier 2 in the longitudinal direction. This can be done by an adhesive 4.
