Definitions

  • the invention relates to a method for producing self-sealing sections in line arrangements, in particular in on-board networks, as well as a multi-wire line arrangement.
  • WO 96/16415 longitudinally watertight sections in predetermined areas of multi-core cable sets are produced in that the interspaces (gussets) present between the individual housings are filled in the sections to be sealed with a sealing compound which hardens after a heat and / or pressure treatment.
  • a wiring harness for example, a commonly used in the automotive industry
  • the bündiförmige wiring set fanned so that the individual wires of the electrical system are first isolated and then fanned out parallel to each other, whereupon an adhesive tape with a sticky layer transverse to the longitudinal direction of fanned out Single cores is glued to the fanned lines.
  • the material of the adhesive layer of the adhesive tape penetrates between the individual wires and forms after completion of the process a watertight block in the respective treated areas of the electrical system.
  • On-board electrical systems are used in vehicles to distribute electrical energy and electrical signals. These on-board electrical systems are predominantly made to customer specifications, which means that the respective on-board electrical systems are tailored to the wishes of the respective car buyer.
  • the electrical system-forming is almost exclusively manual work, whereby for reasons of rationalization, high value is placed on the respective components of a vehicle electrical system before assembly to provide time and type exactly. These components are, for example, single cores, cables, connectors, housings and connectors.
  • Forming of the vehicle electrical system is usually carried out on sloping mobile mounting boards of about 2 m in height and up to 12 m in length.
  • wiring harnesses depend on the scope and design of how much electrical wiring between the power source and consumers in each vehicle are required. Just imagine what consequences a moistened electrical system exerts on the transmission of electrical impulses (on-board computers). Depending on the customer's requirements, vehicles of the same type can require very different on-board electrical systems, depending on the special requests of the motor vehicle customer. On-board electrical systems are usually mounted on suitable mounting boards, the individual wires of a vehicle electrical system, which have been cut to the required lengths, are routed by hand according to a wiring diagram available for each vehicle electrical system.
  • Another disadvantage of the known method is that they provide for longitudinal water-tightness only at a finished vehicle electrical system. Assuming a multi-year life of a provided with such a harness vehicle, so there is a risk that after several years by mechanical effects, chemical agents or other effects, the initially achieved longitudinal water resistance is impaired or even destroyed. Occurs, for example, in the final phase of the useful life of such a vehicle on an event that requires a high longitudinal water-tightness, such a mechanically or chemically impaired sealing system can no longer fulfill its task.
  • SAP superabsorbent polymers referred to as SAP are based in many cases on weakly cross-linked polyacrylates, such as partially neutralized with sodium acrylic acid.
  • Liquid, solvent-free, cross-linking polyacrylates are available for the production of swellable cable components. These allow swellable coatings of different support materials such as fabrics, films, fibers and game, wherein the liquid system forms a homogeneous, water-blocking layer that has good sealing properties in the swollen state.
  • the invention is therefore an object of the invention to provide a method for producingsab Whynder sections in multicore cable arrangements, in particular in on-board networks, which runs regardless of the care and / or the skill of a human worker quality assured and leads to line arrangements, especially on-board networks whose sealing points over long periods of time are safe.
  • the invention is also directed to such a conduit arrangement.
  • Water-swelling polymers are the same and can be used all substances or processes that block by chemical and / or physical effects against water penetration.
  • Water-swelling polymers result in the same substances and / or processes that seal against water z.
  • the achievable with the present invention progress results from the fact that dimensionally fixed sealing points on previously precisely defined sections of individual wires with the help of a water-swelling material are brought about by automated means, in such a way that after completion of an individual wiring harness (wiring harness, line arrangement) the treated Sections meet. If an attack of moisture occurs on a line set equipped in this way, the water-swellable materials enveloping each individual vein over a given section in their longitudinal dimension absorb the attacking water with a strong increase in volume. The interaction of adjacent sealing points thus, so to speak, automatically forms a sealing block penetrating the entire bundle of cables (wiring harness), which effectively prevents the spreading of moisture (water).
  • the aforementioned mode of operation makes it possible to characterize the longitudinally watertight sealing points as "self-sealing systems in cable bundles and components of land, air and water vehicles."
  • Commercial SAP powders can have swelling volumes of more than 500 times their original volume to reach.
  • the water-swelling polymer can be used in a variety of forms, for example powdery, liquid, emulsified, as a gel or as a thermoplastic.
  • the water-swelling polymer can be used without carrier material or with carrier material for Use come, are preferred as the carrier material tapes, yarns, fibers or nonwovens.

  • racks For the manufacture of a vehicle electrical system, goods sold by the meter are taken from the ring or barrel or a drum and cut to the required dimensions for the individual cores. Before the individual wires made of the sold by the meter are combined into a vehicle electrical system, it is ensured that these individual wires are assembled on at least one end, ie stripped or prepared with plugs or otherwise for further use.

  • the automatic coating of the individual cores takes place at predetermined spatial positions which correspond to the sections provided for the longitudinal water seals.
  • the location of these automatically applied polymer coatings is chosen so that in the finished electrical system coated with the water-swelling polymer portions are adjacent to each other. Consequently, in the finished vehicle electrical system, the coated sections of all the individual wires are arranged in correspondence with one another in the same local position (position), namely the sealing point of the vehicle electrical system to be produced.

Abstract

L'invention concerne un procédé pour produire des réseaux de bord dont les unités monofibres sont automatiquement pourvues d'un revêtement constitué d'une quantité prédéterminée d'un polymère gonflant dans l'eau, au niveau d'une zone prédéterminée, avant l'achèvement du réseau de bord. Les revêtements polymères d'un réseau de bord achevé se trouvent à des emplacements correspondants et forment au moins un système autoétanchéifiant et hydrobloquant en présence d'humidité. Des ouvertures et surfaces séparatrices de douilles divisées et fermées sont obturées au moyen d'un polymère gonflant dans l'eau. Des polymères gonflant dans l'eau sont également employés pour réaliser le revêtement intérieur de coffrets de commande et d'autres logements, et servent ainsi à assurer une protection contre l'eau de condensation et à former des garnitures d'étanchéité d'urgence.
