Definitions

  • the subject matter relates to the connection of an electrical cable formed from a plurality of wires or strands with a connection part, in particular for the electrical system of a motor vehicle, with a support sleeve.
  • the support sleeve for receiving an end portion of the cable is formed and surrounds it.
  • the wires or strands are held in the support sleeve, wherein the front side of the cable formed from the individual wires or strands is welded to the connecting part by means of an at least frontal weld.
  • connection of electrical cables with connector parts is commonplace in the automotive industry in particular.
  • the cost pressure is enormous, so that the supplier industry is always looking for process-reliable, durable, but cost-effective connection technologies.
  • EP 2 131 448 A1 is a connection between a cable and a tubular connector known.
  • the cable is welded to a contact element via a support sleeve 4.
  • the contact element is inserted into the tubular connection element in order to be crimped in the manner of a plug in the tube of the connection element.
  • EP 1 032 077 B1 is for example a connection of an aluminum cable with a connecting part, which may be formed of copper known.
  • a connecting part which may be formed of copper known.
  • the end of the aluminum cable, in particular the stripped end of the aluminum cable is pressed by means of a sleeve, so that the strands of the cable are miteihander pressed.
  • the thus-pressed end of the cable is connected to a connection part by a friction welding process.
  • connection parts since for the first time the possibility was created to connect aluminum process-reliable and permanently with other joining partners, in particular copper or brass.
  • the sleeve ensures that the strands of the aluminum cable do not splice during the welding process. This ensures that a good intermetallic connection is created between the end faces of the strands and the connection part. This is an important prerequisite for a permanent, electrically good conductive connection.
  • connection part is formed of a solid material. On the one hand, this is difficult and therefore no longer up to date in the context of the necessary weight reduction in vehicle construction. On the other hand, such a connection part is expensive, since the use of material is considerable. Finally, the connection part is also complex to produce, since it must be made available as a forged part usually, which is expensive to manufacture.
  • the object was the object to provide a connection of a cable with a connector available, which is on the one hand process reliable, on the other hand, however, material and weight savings.
  • connection part is preferably formed from a sheet metal or strip, which has a bearing surface / connection surface facing the support sleeve and the end region of the cable.
  • the fact that the connection part is hollow on the side opposite the weld results in weight and material savings.
  • the connector may provide at one end a crimping shoe, a bore, a bolt, a threaded connection or the like, via which the connection with a copper cable is made possible.
  • the connecting part On the side facing the cable, the connecting part has a preferably circular connection surface, which is preferably flat.
  • the cable together with the support sleeve can be attached to this connection surface and welded to it.
  • Both pad and cable preferably have circular cross sections, but other cross sections are also possible and within the scope of what is claimed objectually.
  • Hollow in the sense of the article is to be understood in that on the opposite side of the weld, a space defined by walls of the connection part is formed. This room can be open on one side, but also completely closed.
  • hollow means that an at least partially circumferential wall is provided along the circumference of the weld.
  • An end region of the cable is in particular the region of the cable which is stripped.
  • the end face of the cable is preferably formed by the ends of the wires or strands.
  • the cable has been cut or cut so that a flat as possible end side of the cable is formed.
  • the strands thus end preferably in a plane, in which case a tolerance range of +/- 1 to 2 mm is possible.
  • connection part is tubular.
  • the connection part has a bottom, which forms the connection surface for the weld seam.
  • the floor is welded to the cable along the weld. It is also possible that the weld extends beyond the cable to the support sleeve. In this case, the pad is welded to the support sleeve as well as the end face of the wires or strands.
  • the floor is formed integrally from the walls of the connection part.
  • a tubular connecting part is formed. Subsequently, the ends of the tube are bent toward the center of the tubular connection part so that the bottom forms.
  • the bottom is formed from a lid arranged at the end of the tube of the connecting part.
  • the lid is preferably inserted in the tube or placed on the tube.
  • the lid is crimped in the tube.
  • the lid has a step-shaped cross section, such that a first Diameter corresponds to the inner diameter of the connecting part and a second diameter at least equal to the outer diameter of the connecting part, but at least greater than the inner diameter. Then, the first diameter of the lid can be inserted into the tube of the connecting part, wherein the second diameter rests against the end face of the tube. Subsequently, the lid can be pressed in the tube. It is also possible that the lid is welded to the tube. Finally, it is possible that the lid is soldered or glued to the pipe. Other connection technologies are also possible as long as there is an electrical connection between the cover and the connection part. The pipe surface facing away from the lid then forms the connection surface.
  • the wall of the connecting part is deformed forming the bottom at its end.
  • the wall of the connection part can be bent inwards, in particular in the region of the front end.
  • the wall is preferably bent to the center of the tubular connection part.
  • connection part in the region of the bottom is a drawn, in particular deep-drawn, cup.
  • the connection part may for example be a flat part, which is formed in a drawing process so that it forms a tubular, U-shaped, unilaterally open connection part at least at the end.
  • the outwardly facing surface of the cup serves as a connection surface for the weld.
  • connection part can be formed from a flat part. Then, for example, in a first processing step of a sheet or a strip, the flat part are punched, which has the necessary developments. Subsequently, the flat part can be deformed, in particular bent at the ends tubular, in which case the soil can be formed. Finally, the objective connection part is then formed from the flat part.
  • the mutually facing end faces are positively connected to each other, in particular schwalbenschwänzig engage behind each other.
  • a region of the flat part may, for example, be rectangular.
  • the respectively opposite end faces of the flat part can have corresponding projections and recesses, in particular dovetailed projections and recesses.
  • a circular extension is formed, which forms the bottom in the deformed state.
  • the flat part may be rectangular in a development in a first region. This area can be deformed tubular.
  • a circular extension can be arranged on the rectangle, on a long end face.
  • the flat part can be formed, for example by stamping so that both the rectangle, and the extension is punched directly from a sheet.
  • the extension after the tube has been formed, be bent so that it rests or rests on the end face of the tube. Then it can be welded, soldered or glued to the front of the pipe.
  • connection part can be formed particularly cost-effectively if it is a tubular cable lug.
  • a tubular cable lug is available as a mass-produced particularly favorable.
  • To form the objective connection part it is only necessary to deform the front ends of the open region of the tubular cable lug into a base or to place a cover thereon.
  • connection between the support sleeve, the cable and the connection part is advantageously realized via the weld.
  • This is advantageously a friction weld, a Rotationsreibsch spanaht, a resistance weld, a laser weld or a Ultrasonic weld.

  • the cable can be made of aluminum or an aluminum alloy.
  • the connection part may be formed from a conductive, preferably formable material.
  • non-ferrous metals such as copper or copper alloys such as brass or bronze are suitable here.
