Definitions

  • the present invention relates to a process for forming a compact-stranded wire conductor and in particular to forming acompact-stranded wire conductor to be used in wire harnesses for motor vehicles.
  • Wire harnesses are typically used in the various electrical systems of motor vehicles, and with the growing advancement in the technology of such electrical systems, the number and complexity of associated wirings has had to increase accordingly. This increase in complexity is especially evident for the-growing number of electrical systems that operate on low electrical currents, such as indicator lights and the like. For this reason, the current trend has been to try to reduce the overall weight of the wire harness by reducing the diameter of the individual wire conductors comprising the wire harness.
  • a compact-stranded wire conductor 1 comprises a central element wire 2 and peripheral element wires 3 provided around the central element wire 2, with spaces 4 and 4' existing between the element wires 3 and the central element wire 2 and between the element wires 3 themselves, respectively.
  • Fig. 1 further illustrates that the element wires 2 and 3, having originally been circular in cross section, become deformed when they are circularly compressed, such as by die drawing, to form the the compact-stranded wire conductor 1.
  • the spaces 4 and 4' are reduced in size relative to what they were before the element wires 2 and 3 were circulary compressed, thus leading to reduction in the overall size of the wire conductor 1.
  • both the central element wire 2 and the peripheral element wires 3 undergo deformation and thereby take on somewhat random shapes, which in turn causes the spaces 4 and 4' to become a little scattered and also take on somewhat random patterns.
  • the compact-stranded wire conductor so produced does not possess sufficient overall strength if its diameter is made relatively small, and it is even possible that the electrical conductivity of one or more of the element wires could be adversely affected due to such deformations.
  • the slightly random nature of the deformations tends to give rise to a loss in the overall circularity of the wire conductor, which necessitates the provision of a thicker layer of insulating material in order to properly cover the wire conductor.
  • GB-A-2 160 554 describes a method of producing a compact conductor by laying-up pre-shaped wires around a circular central conductor.
  • It is still a further object of the present invention provide a method of forming a compact-stranded wire conducto in which only the peripheral element wires undergo substantial deformation when the compact-stranded wire conductor is manufactured.
  • a process for forming a compact stranded wire comprising: providing a central element wire enclosing the central element wire with a plurality of peripheral element wires; and compressing the peripheral element wires against the central element wire to reduce the size of the spaces between the wires characterized by providing a central element wire with a hardness greater than that of the peripheral element wires.
  • Fig. 1 is a cross-sectional view of a prior art compact-stranded wire conductor.
  • Fig. 2 is a cross-sectional view of a compact-stranded wire conductor according to the present invention.
  • Fig. 3 is a graph showing the associated limiting currents for the various diameters of the same wire conductors shown in Fig. 4.
  • Fig. 4 is a graph showing the associated breaking loads for various diameters of two compact-stranded wire conductors according to the present invention in comparison with defined standards.
  • a compact-stranded wire conductor 1 comprises a central element wire 2 and peripheral element wires 3 concentrically placed around the central element wire 2.
  • either single or stranded wires can be employed for both the central element wire 2 and the peripheral element wires 3, but any and all choices made must be such that the central element wire 2 has a higher hardness than that of the peripheral element wires 3.
  • the use a wire having both high hardness and high strength for the central element wire 2 is preferred, such as a wire made from stainless steel, copper alloy or the like.
  • a wire made from stainless steel, copper alloy or the like it should be noted that the choice should be made even at the sacrifice of a small loss in the limiting current, because for low currect electrical systems such a minor loss will have no adverse effect.
  • peripheral element wires 3 soft or hard copper wires or copper alloy wires may be used so long as they have hardnesses smaller than that of the wire chosen for the central element wire 2. However, it is recommended that wires having slightly high hardnesses, such as stainless steel wires, be used for the peripheral element wires 3 when a high-hardness copper alloy wire is being employed for the central element wire 2.
  • limiting currents of examples A and B and standards C and D are shown for various diameters, with the dashed line P indicating a minimum limiting current of 3 amperes re quired for wire conductors which are to be used in wire harnesses for motor vehicles.
  • the maximum temperature and the ambient tem perature of the conductor during use were 80°C and 60°C, respectively.
  • L represents a minimum breaking load a 10kgf that must be achieved in order for the wire conductor to be considered to have adequate strength characteristics.
