Abstract
A double busbar device for a vehicle includes a first busbar unit, a second busbar unit, and a summation shielding unit. The first busbar unit includes an insulating first sheath layer element. The second busbar unit includes an insulating second sheath layer element. The first and second busbar units are arranged insulated from one another at least by means of the first and second sheath layer elements and follow a course of the double busbar device. The summation shielding unit includes a tubular shielding element made of solid metal. In a cross-section transverse to the course of the double busbar device, the first and the second busbar units each have their outer surface in mechanical contact with an inner surface of the summation shielding unit over a large area.

A double busbar device for a vehicle, the double busbar device comprising:
- a first busbar unit including an insulating first sheath layer element;
- a second busbar unit including an insulating second sheath layer element, the first and second busbar units arranged insulated from one another at least by the first and second sheath layer elements and following a course of the double busbar device;
- and
- a summation shielding unit including a tubular shielding element made of solid metal, the first and the second busbar units each having their outer surface in mechanical contact with an inner surface of the summation shielding unit over a large area in a cross-section transverse to the course of the double busbar device.
A method for producing a double busbar device for a vehicle, the double busbar device including a first busbar unit with an insulating first sheath layer element, and a second busbar unit insulated from the first busbar unit with an insulating second sheath layer element, and a summation shielding unit with a tubular shielding element made of solid metal, the method comprising:
- providing the first and second busbar units;
- inserting the first and second busbar units into the tubular shielding element made of solid metal, there being a clearance between the first and second busbar units and the tubular shielding element;
- first rolling of the tubular shielding element onto the first and second busbar units, in which play between the first and second busbar units and the tubular shielding element is reduced to zero in at least one direction, so that in a cross-section transverse to a course of the double busbar device, a first part of an inner surface of the summation shielding unit bears against the first and second busbar units;
- and
- second rolling of the tubular shielding element against the first and second busbar units, in which a further part of the inner surface of the summation shielding unit, which differs from the first part, is brought into contact with the first and second busbar units.
