A holding apparatus (15) for current and signal conductors of a traction battery of a motor vehicle has a plate-like base body with longitudinal sides (16), transverse ends (17) and a top (18) and bottom (19) extending between the longitudinal sides (16) and transverse ends (17). Elements (20) are arranged on the top (18) and the bottom (19) for guiding and fixing current conductors (12) of the traction battery, and elements (21) are arranged on the other of the top (18) and the bottom (19) for guiding and fixing at least one signal conductor (14) of the traction battery. The base body provides EMC shielding of the signal conductor (14) from the current conductors (12). The plate-like base body has on the opposite longitudinal sides (16) and/or on the opposite transverse sides (17) sections (22) for securing and grounding the holding apparatus on a frame of the motor vehicle.

The outer layer is peeled exactly a predetermined length from the end portion of the electromagnetic shielding tube. That is, the metal layer is exposed exactly a predetermined range at the end portion of the electromagnetic shielding tube. A flexible conductor is connected to the exposed metal layer. A separated portion is provided in the inner layer. The separated portion is formed along the length direction of the electromagnetic shielding tube. Additionally, a depth of the separated portion is the same value as the thickness of the inner layer. As such, the inner surface of the metal layer is exposed at the separated portion. It is preferable that the separated portion be formed at a plurality of locations in the circumferential direction. The inner layer is divided into a plurality of sections in the circumferential direction by the separated portion. The separated portion is a terminal processed portion, which mitigates the effects caused by differences in the physical properties of the inner layer and the metal layer.

A flexible flat cable (FFC) includes a first insulation layer, at least one pair of conductors, a plurality of low-k dielectric layers, two second insulation layers, and at least one shielding layer. The pair of conductors is located within the first insulation layer. Each pair of conductors includes a plurality of first conductors, and the first conductors are axially extending and arranged in parallel. The low-k dielectric layers are embedded in the first insulation layer. Each of the pair of conductors or each of the first conductors is covered and surrounded with one low-k dielectric layer. The two second insulation layers are located on two surfaces of the first insulation layer. The shielding layer is located on the two second insulation layers opposite to the first insulation layer.

A shielded harness is simply constructed such that covered wires are fitted into a groove of a molded body, and then an opening of the groove is covered with a metal casing. This simple structure allows noise to be released to the metal casing, which functions as a ground, via a metal plate constituting the molded body when the noise is generated at a control system unit or comes from an external device. The metal casing of the shielded harness can be used as a housing of a device, such as a power converter, and therefore, a fixing tool is not required for wiring, and the wiring is made easy. Moreover, compared with a conventional shielded wire, this shielded harness has a small number of parts and is produced by an easy method, thereby allowing reduction in production cost.
