Definitions

  • the invention relates to a battery terminal cable with one strand a variety of fine wires and another part with a hole for a screw, the other part being the multitude of fine wires is welded together, a process for the manufacture of a Battery pole connection cable and a device for producing a such cable.
  • Battery terminal cables are mainly used to galvanically connect battery cells to each other.
  • the strand usually consists of copper wires that are twisted into a strand with a cross section of approximately 50 mm 2 .
  • thicker and thinner strands are also used.
  • Battery poles In order to prevent the screws from loosening, known ones Battery poles a plastic part, such as preferably a plastic ball, in Thread area arranged between the screw and the battery pole. This ball deforms when the screw is screwed in and has an effect loosen the screw.
  • a generic battery pole connection is from EP-A-0 707 321 known.
  • the end of the manufactured by spot welding In practice, cable strands do not lead to the required Strength values of the cable end, so that the cables described have not proven themselves as battery pole cables.
  • the invention is based, an inexpensive task Connection between battery pole connection cable and battery pole to be provided, even in the event of severe vibration or Thermal expansion of the battery terminal cable on the system Battery pole guaranteed.
  • This task is done with a generic Battery pole connection cable loosened, in which the strand is at least partially is insulated and the other part is attached to the end of the strand.
  • the invention is based on the knowledge that the problem of Loosen the screw in the battery pole not primarily on insufficient ones Hold the screw in the battery pole.
  • the cause in itself Loosening screws is that the contact piece of the Battery pole connection cable temporarily higher due to the flowing currents Temperatures occur. With changing temperatures, the fine wires inside the button sleeve sometimes stronger pressed together and then remain in the more compressed form. This will result in repeated temperature fluctuations originally tightened screw opposing less force, so that the screw is looser in the thread. A loosening of the screw can then only prevented with the plastic part described above become.
  • the plastic part prevents the screw from loosening, the fact that the screw temporarily less pressure on the Exercises contact piece is not prevented by the plastic part. On constant pressure on the contact piece is, however, required to achieve a to ensure constant good current flow.
  • another part is attached to the end of the strand.
  • This further part can serve as a contact piece and is in various ways with the welded to a solid material Connectable at the end of the line.
  • a particularly preferred embodiment of a Battery terminal cable is created when the other part at the end of the Stranges is welded.
  • a particularly cheaply shaped one Contact piece can be used. This enables, above all, that Reduce the weight of the battery terminal cable.
  • the further one - preferably as a contact piece trained - part is made of copper.
  • the connecting cables in the Practice often very strongly curved.
  • the angular arrangement of the further part to the axis of the battery terminal cable reduced in many Cases the necessary bend of the cable and allows it above out using shorter cables.
  • the arrangement described leads thus that the cables are protected and the use of materials can be reduced.
  • the angular arrangement described is also independent of those previously Features described for battery terminal cables of large Significance and can therefore also be used, for example, for clamp connections can be used advantageously between the cable harness and another part.
  • the object of the invention is also achieved with a method for Manufacture of a battery pole connection cable solved in which one strand is ultrasonically welded from a large number of fine wires and the strand to a contact piece or with a contact piece is welded.
  • EP-A-0 671 790 does indeed use ultrasound Making electrical connections known. The welding of the Strands to a contact piece or with a contact piece is this slogan, however, cannot be found.
  • a sonotrode a Strand feeder, a contact piece feeder and one Has printing cylinder, which is arranged so that the strand with it and the contact piece can be pressed together.
  • Act according to the invention movable jaws perpendicular to the axis of the impression cylinder on the strand.
  • This device allows an automatic, fast production of the Battery pole connection cable.
  • movable jaws arranged transverse to the axis of the impression cylinder act on the strand.
  • the battery terminal cable 1 shown in Figures 1 and 2 consists in Essentially from a strand 2 of a large number of fine wires, which in a middle area is surrounded by insulation 3. His at both ends is the strand 2 to a flattened end 4 or 5 pressed together. At this flattened end there is a contact piece 6 or 7 welded.
  • the contact pieces 6 and 7 have one in the Thickness reduced area 8 or 9, in which the flattened part 4th or 5 of the strand 2 by means of an ultrasonic welding process is welded on.
  • At the reduced part 8 of the Contact piece 6 closes an area 10 which is somewhat thicker in thickness or 11 with a central bore 12 or 13.
  • the holes 12 13 serve the contact piece via a plugged into the bore Attach the screw (not shown) to a battery post (not shown).
  • the areas 4 and 5 of the strand 2 are through the welding process at least partially relatively homogeneous, since the large number of fine wires in it Area is fused into a solid piece of metal.
  • the wires and the contact piece are made of copper.
  • the contact piece can also be made from brass.
  • the battery pole connecting cable prepared in this way is, as shown in FIG. then at its ends in a known manner with a Insulation material 14 encapsulated.
  • the strand 2 and in particular the end 5 completely surrounded with insulation material.
  • On the Top 15 of the contact piece 7 is a contact surface for the Screw head (not shown) is provided and on the underside 16 of the Contact piece 7 is a contact surface for contact piece 9 a battery post (not shown).
  • a sonotrode 17 made of titanium the end 5 of the strand 2 of the multitude of fine wires and above the contact piece 7 is positioned so that the end 5 at narrower area 9 of the contact piece 7 is present. Then with Pressure a cylinder 18 to the sonotrode 17 move so that between the cylinder 18 and the sonotrode 17, the narrower end 9 of the Contact piece 7 and the end 5 of the strand of fine wires be pressed together.
  • Sonotrode on the one hand the fine wires of the end 5 with each other welded and on the other hand at the same time with the contact piece welded.
  • the top view shown in FIG. 5 shows the entire device 19 movable jaws 20 and 21, which are before the compression of Contact piece 7 and strand 2 are brought up to strand 2 so that when compressing the wires by means of the pressure cylinder 18 individual wires cannot dodge to the side.
  • the shape of the jaws 21, 22 to the shape of the narrower End 9 of the contact piece 7 adapted.
  • the entire process can be done, as the above explanations show, easily automate the strand 2 with a Strand feed device (not shown) and the contact piece 7 with a Contact piece feeder (not shown) led to the sonotrode 17 and then there by means of the jaws 20, 21 and the cylinder 18 are held while the sonotrode 17 is the wires of the strand 2 welded to the contact piece 7. Then the Holder devices 18, 20 and 21 loosened, the finished welded Battery terminal cable removed and the next parts fed. The The battery pole connection cable removed is ultimately, as shown in FIG. 3, surrounded at its ends with an insulation layer 14.
  • the method described allows rapid automated production of battery pole connection cables and increases the quality of the cables as a result of the homogeneous connection of the individual wires with each other a loosening of the used battery pole screw is prevented. More accurate calculations also allow the amount of metal used, such as in particular to reduce the copper used.
  • Figures 6 to 9 show different variants for the arrangement of the Contact piece 7 on the harness 2.
  • the other part 4 has together with the contact piece 7 a longitudinal extension in the direction of the axis 22, the in the present case at an angle of 90 ° to the longitudinal axis 23 of the Harness 2 runs.
  • Figures 8 and 9 show two different ways that To weld individual cables to the contact piece at an angle. While in 8 the strand end 2 in the direction of the course of the contact piece 7 is bent, the wires of the strand 2 run in the embodiment in Figure 9 in the direction of the axis 23 of the strand 2 and thus in one Angle to the longitudinal axis 22 of the contact piece 7.
