Definitions

  • the subject matter relates to a motor vehicle power line, in particular a battery line of a motor vehicle, having a first battery-side end and a second end, wherein the motor vehicle power line comprises a metallic flat conductor and an insulation surrounding the metallic flat conductor, and wherein the motor vehicle power line is formed in a region as a Fremdstartstütztician ,
  • the subject also relates to the use of such a motor vehicle power line in a motor vehicle.
  • a third party start device for a battery of a motor vehicle is known. It is proposed to integrate a T-shaped support member in a flexible ground cable. On the support part, a brass sleeve is screwed, which forms the connection for a Polzange a Fremdstart advocatess. Due to the flexibility of the ground cable the Fremdstartstützddling can be released from a holder and rotated in an accessible position of use.
  • the proposed solution has several disadvantages.
  • the solution can only be implemented in conjunction with conventional flexible cables consisting of ground wires; the use of flat conductors with larger cross-sectional area is difficult because of the higher rigidity.
  • the production of the external launching device is complex, since a separate carrier part must be integrated into the ground cable.
  • the brass sleeve which is likewise designed as a separate component, must be screwed onto the carrier part.
  • a motor vehicle power conductor which may be formed as a flat conductor. It is suggested as Foreign starter base to connect a connecting bolt with the flat conductor.
  • the connecting bolt has at one end a pin with a thread which can be screwed into a hole provided for this purpose in the flat conductor.
  • the complex production is disadvantageous. Since the connecting bolt is designed as a separate component and is to be screwed to the flat conductor, a thread must be produced both in the flat conductor and on the connecting bolt. In addition, depending on the bolt material used, contact corrosion as well as loosening of the screw connection can occur.
  • the object is therefore the object of the initially described and previously described in detail motor vehicle power line in such a way and further, that in a simple and cost-effective manner, a connection option for a starting aid device is created.
  • the object is achieved in that the second end is a free end, and that the motor vehicle power line is formed in the region of the second end as a bent Fremdstartstütztician.
  • Automotive power lines are lines that not only transmit signals or the like, but are suitable for transmitting very high currents and power.
  • Motor vehicle power lines are used in particular as a battery cable, so as a connection between a vehicle battery and a generator / starter and must therefore have a very high current carrying capacity.
  • Charging currents or starting currents in vehicles are regularly 100 amperes and more, often even several hundred amperes.
  • a part of the motor vehicle power line itself as a foreign start support point, ie as a contact point for connecting a third-party start device, it is possible to dispense with separate connection parts such as bolts, sleeves or the like. It can therefore be dispensed with elaborate joining methods that would be necessary for attaching separate parts.
  • the jump starting point can be formed as an insulation-free contact point by the insulation of the metallic flat conductor is removed in a defined range.
  • the metallic flat conductor can not be provided with insulation in a defined region during production. In this way, a third-party starting device, in particular a Polzange or Fremdstartzange a jumper cable, be clamped directly to the bare metallic flat conductor.
  • the jump starting point is arranged as a bare contact point between the first and the second end of the motor vehicle power line.
  • a bare contact point is a point at which the metallic flat conductor is free of insulation and therefore directly accessible.
  • the jump starting point in the region of the direct and immediate connection between the first end and the second end of the motor vehicle power line is arranged and is not arranged in a branch or on another arm.
  • Vehicles are regularly equipped with a wide network of electrical wiring, also referred to as a wiring harness. In modern vehicles, the wiring harness may be of considerable mass and complexity.
  • This embodiment has the advantage that the motor vehicle power line does not have to have any further ends, arms or branches, so that the mass and complexity of the line system is not further increased.
  • the jump starting point be arranged between two adjacent isolated sections of the motor vehicle power line.
  • the jump starting point By removing the insulation of the motor vehicle power line only locally in the area of the jump starting point, it may be possible to arrange the jump starting point at almost any point of a motor vehicle power line. Complete removal of the insulation is possible but not required. It is also possible, although not required, to completely remove the insulation from the launching support point to an end of the motor vehicle power line.
  • the claimed subject matter provides that the second end is a free end, and that the motor vehicle power line is formed in the region of the second end as a bent jump starting point.
  • a free end is understood to mean an area of the motor vehicle power line to which no producer or consumer is connected.
  • One free end may be intended for connection of a third party start device.
  • the metallic flat conductor is U-shaped in the region of the external starting support point.
  • the flat conductor can be bent in the form of a hook or in the form of an S or Z contour in the region of the foreign launching support point.
  • Flat conductors are usually characterized by a cross section with a small height and a significantly greater width. The connection of a Polzange a starting aid device may be difficult due to this cross-sectional shape.
  • Conventional pole tongs have a metal spring whose clamping force increases with increasing opening angle of the pole tongs. In other words, the clamping force of the pole tongs is low when the pole tongs are only slightly opened. With very wide open pliers, the clamping force is high.
  • the problem may arise that the low height of the flat conductor causes too little clamping force in the pole. In particular, in the case of moisture or vibration, there is therefore the risk that the pole tongues slip off the foreign launch base.
  • the large width of flat conductors leads to the fact that the Polzange is very difficult to create, since the opening angle of Polzangen is structurally limited.
  • This problem can be solved by transforming the motor vehicle power line in the region of the jump starting point, in particular bent over, so that a U-shaped contact point is formed. Under a U-shape is understood in particular a form in which the metallic flat conductor is bent for example by at least 180 °.
  • the Fremdstartstütztician has a clamping width which is greater than the height of the flat conductor, which is smaller than that Width of the flat conductor.
  • the motor vehicle power line has a third, free end and that the motor vehicle power line is formed in the region of the third, free end as a foreign launch base.
  • the jump starting point can be arranged even more variable in the engine compartment.
  • the end region of the free end may be formed as a foreign start support point.
  • the free end may branch off from the direct connection between the first end and the second end or, for example, from a potential bar.
  • a good electrical conductivity can be achieved according to a further embodiment by the metallic flat conductor is formed of aluminum or copper.
  • Aluminum also has the advantage of a particularly low density, whereby the mass of the motor vehicle power line can be reduced. Pure aluminum 99.5% EN AW1050A or 99.7% EN AW1070A has proven particularly suitable due to its very good conductivity.
  • the metallic flat conductor has a rectangular cross section. Rectangular profiles can be made particularly simple and therefore inexpensive. A particularly high flexibility of the metallic flat conductor can be achieved if the height of the flat conductor in relation to its width is particularly low. In practice, width / height ratios of 2 to 1 to 12 to 1 have proven successful; Width / height ratios of 2.5 to 1 to 6 to 1 are preferred. Particularly in the case of aluminum flat conductors, the width of the metallic flat conductor can be at least three times its height, so that the quotient of the width of the metallic flat conductor and the height of the metallic flat conductor is greater than or equal to three.
  • the cross-sectional area is preferably in the range between 16 mm 2 and 160 mm 2 , in particular in the range between 50 mm 2 and 120 mm 2 .
  • cross-sectional areas in the range between 30 mm 2 and 75 mm 2 are preferred.
  • a further embodiment provides that the cross-sectional area of the metallic flat conductor in the region of the foreign starting support point is identical or smaller than in the other regions of the metallic flat conductor.
  • the advantage of a smaller cross-sectional area lies in a better contact between foreign launching pliers and flat conductor.
  • An identical cross-sectional area has the advantage of a constant current conductivity and a uniform heating.
  • the width of the metallic flat conductor in the region of the jump starting point is identical or lower than in the other areas of the metallic flat conductor.
  • the width may preferably be reduced to such an extent that the width and the height of the metallic flat conductor are approximately identical in the region of the jump starting point.
  • the cross-sectional area of the metallic flat conductor may be square in the area of the jump starting point.
  • the motor vehicle power line has a removable, electrically insulating cover in the region of the external starting support point.
  • An electrically insulating cover protects the jump starting point from accidental contact and an associated short circuit.
  • the cover also provides protection against dust and moisture.
  • the cover is removable.
  • the cover is manually, so removable without tools.
  • the cover is designed as a protective cap, in particular as a pivotable plastic protective cap.
  • a pivotable protective cap has the advantage that the protective cap can be opened and closed again without falling into the engine compartment or on the ground.
  • the protective cap is thus permanently connected to the motor vehicle power line.
  • the connection may in particular be formed by a film hinge or a hinge.
  • the use of plastic has the advantage of very good electrical insulation properties and favorable manufacturability, such as by injection molding.
  • a particularly simple and secure connection of a starting aid device can be achieved by the cover according to a further embodiment having a polarity marking, in particular a color marking and / or a symbol.
  • a polarity marking in particular a color marking and / or a symbol.
  • marking the polarity such as a plus or minus symbol, even less experienced users can reliably detect whether the plus or the minus pole must be connected to the jump start point.
  • starter cables are also color coded, with the cable for the positive pole being red and the cable for the negative pole being black.
