Definitions

  • the invention relates to a connector with cable, a method of making the connector with cable, and a tool for making a cable connector.
  • the increasing variety of electrically or electronically controlled devices requires the use of cables that include a plurality of conductors. It is essential that the conductors are still well insulated from each other, to avoid crosstalk. When using such cables in automobiles, a further problem is to achieve a precise connection of the cables with connectors, which is stable against mechanical vibrations and vibrations.
  • Such connectors are known in a variety, while the connectors are designed for receiving flat cables containing a plurality of conductor strips.
  • the connectors often include two types of connections, one of which serves to electrically connect the connector to a conductor of the cable and the second connection is a mechanical connection. This mechanical connection is essentially the train protection and causes even the smallest movements of the contact against the conductor can be avoided or can be completely ruled out.
  • Such mechanical connections can be achieved, for example, by bonding the jacket made of an insulating material of the cable to the dielectric housing of the connector. It is also known to weld the jacket of a cable to a connector housing. In addition, there are also punched joints, where one not penetrated by a conductor part of the cable is connected to the housing of the connector. For example, a rivet is knocked into the connector housing by the cable. All of the mentioned types of connection of connectors, in particular connector housings and cables require due to the achievable precision of the electrically conductive connection of the conductor to the contact also a high degree of accuracy in the manufacture of the connector and in the generation of the cable end, with the Connector to be connected.
  • the manufacture of the connector and the production of the cable end to be used for connection is carried out under high quality standards with largely automated machines. As a result, a high quality of the connection of plug and cable can be achieved.
  • the connectors are often used in widely branched cable connections, where they are used both in central cable strands and in branched side arms.
  • the connectors are preferably designed as a connector, so that the corresponding cable branches are easily connected to each other or can be branched off from a main strand.
  • Connectors are used in the automotive industry, for example, to connect the components of the electronically controlled ignition system with each other or to control the security elements such as airbags electrically. Furthermore, they find use in the entire electrical system, and in particular in the controlled by the battery of the automobile and the alternator of the automobile lighting system. All arranged on the steering column elements are substantially electrically connected to the parts driven by them.
  • the array density in the steering column which is typically a cable harness containing numerous cables, makes it difficult to make a necessary repair perform. In order not to have to replace the entire wire harness, which is very costly, the cables are cut in case of failure of a cable or a connector damage and locally replaced the faulty spot either by bypass lines or a new connector attached. Here, there is the problem that these repairs can be carried out essentially only manually in poorly accessible places.
  • connection arrangement for connecting a flat cable with connections is known.
  • the conductors of the flat cable are held by a lower layer of the flat cable and the conductors are connected to terminals of an external component.
  • several conductors are connected to a plurality of terminals of the external component.
  • miniaturized conductors and connections can be interconnected.
  • pre-positioning accuracy is achieved by mutually locking cutouts attached to the flat cable and protrusions on the external component. The relative positions of the conductors of the flat cable and the terminals of the external component are thus exactly predetermined.
  • connection arrangement thus allows the replacement of a defective flat cable or a no longer functional component without a manual connect, such as a manual soldering process. Also in this connection arrangement, the difficulty is that they can be used only at the points for connecting flat cables and a defective and thus to be replaced connector or component, which are accessible to the necessary welding device. At Inaccessible positions in the engine compartment of an automobile, for example, the use of such a connection arrangement thus provides no advantages.
  • connection with another cable it is also possible, instead of the connection with another cable, to rivet or caulk the uncovered ends of the conductors with connection pins, with the turned-back ends of the cover films serving as reinforcing underlay. A direct connection of the conductor of the first cable and another cable is not provided.

  • the invention has the advantage that a connector or a flat cable can be connected together in an electrical unit so that the connection corresponds to the standard in the factory first connection of both parts.
  • Another advantage of the invention is to be considered that the replacement of a connector and / or a cable in an electrical unit can be done quickly and easily and thus cost.
